open-iscsi/0015-Remove-iscsiuio-source-code.patch
Wenchao Hao 6648d72aeb Remove unnecessary tool iscsiuio 
iscsiuio is used in conjunction with specific linux driver to
improve performance, such as QLogic NetXtreme II or QLogic CNIC driver.
It is not a necessary tool of open-iscsi.

What's more, iscsiuio used a package uio which is out of maintain now,
which would introduce CVEs unhandled. So I want to remove this tool
from open-iscsi.

Subject: [PATCH 2/3] Remove iscsiuio source code
iscsiuio is to be used in conjunction with specific linux driver to
improve performance, such as QLogic NetXtreme II or QLogic CNIC driver.
It is not a necessary tool of open-iscsi.
What's more, iscsiuio used a package uio which is out of maintain now,
which would introduce CVEs unhandled. So I want to remove this tool

-Installation Instructions
-*************************
-
-Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
-2006, 2007, 2008 Free Software Foundation, Inc.
-
- This file is free documentation; the Free Software Foundation gives
-unlimited permission to copy, distribute and modify it.
-
-Basic Installation
-==================
-
- Briefly, the shell commands `./configure; make; make install' should
-configure, build, and install this package. The following
-more-detailed instructions are generic; see the `README' file for
-instructions specific to this package.
-
- The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation. It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions. Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
- It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring. Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.
-
- If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release. If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
- The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'. You need `configure.ac' if
-you want to change it or regenerate `configure' using a newer version
-of `autoconf'.
-
-The simplest way to compile this package is:
-
- 1. `cd' to the directory containing the package's source code and type
- `./configure' to configure the package for your system.
-
- Running `configure' might take a while. While running, it prints
- some messages telling which features it is checking for.
-
- 2. Type `make' to compile the package.
-
- 3. Optionally, type `make check' to run any self-tests that come with
- the package.
-
- 4. Type `make install' to install the programs and any data files and
- documentation.
-
- 5. You can remove the program binaries and object files from the
- source code directory by typing `make clean'. To also remove the
- files that `configure' created (so you can compile the package for
- a different kind of computer), type `make distclean'. There is
- also a `make maintainer-clean' target, but that is intended mainly
- for the package's developers. If you use it, you may have to get
- all sorts of other programs in order to regenerate files that came
- with the distribution.
-
- 6. Often, you can also type `make uninstall' to remove the installed
- files again.
-
-Compilers and Options
-=====================
-
- Some systems require unusual options for compilation or linking that
-the `configure' script does not know about. Run `./configure --help'
-for details on some of the pertinent environment variables.
-
- You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment. Here
-is an example:
-
- ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
- *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
- You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory. To do this, you can use GNU `make'. `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script. `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
- With a non-GNU `make', it is safer to compile the package for one
-architecture at a time in the source code directory. After you have
-installed the package for one architecture, use `make distclean' before
-reconfiguring for another architecture.
-
- On MacOS X 10.5 and later systems, you can create libraries and
-executables that work on multiple system types--known as "fat" or
-"universal" binaries--by specifying multiple `-arch' options to the
-compiler but only a single `-arch' option to the preprocessor. Like
-this:
-
- ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
- CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
- CPP="gcc -E" CXXCPP="g++ -E"
-
- This is not guaranteed to produce working output in all cases, you
-may have to build one architecture at a time and combine the results
-using the `lipo' tool if you have problems.
-
-Installation Names
-==================
-
- By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc. You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX'.
-
- You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
- In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files. Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
- If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
- Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System). The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
- For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Particular systems
-==================
-
- On HP-UX, the default C compiler is not ANSI C compatible. If GNU
-CC is not installed, it is recommended to use the following options in
-order to use an ANSI C compiler:
-
- ./configure CC="cc -Ae"
-
-and if that doesn't work, install pre-built binaries of GCC for HP-UX.
-
- On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
-parse its `<wchar.h>' header file. The option `-nodtk' can be used as
-a workaround. If GNU CC is not installed, it is therefore recommended
-to try
-
- ./configure CC="cc"
-
-and if that doesn't work, try
-
- ./configure CC="cc -nodtk"
-
-Specifying the System Type
-==========================
-
- There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on. Usually, assuming the package is built to be run on the
-_same_ architectures, `configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-`--build=TYPE' option. TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
- CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
- OS KERNEL-OS
-
- See the file `config.sub' for the possible values of each field. If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
- If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
- If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
- If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists. Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
- Variables not defined in a site shell script can be set in the
-environment passed to `configure'. However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost. In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'. For example:
-
- ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf bug. Until the bug is fixed you can use this workaround:
-
- CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-`configure' Invocation
-======================
-
- `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
- Print a summary of all of the options to `configure', and exit.
-
-`--help=short'
-`--help=recursive'
- Print a summary of the options unique to this package's
- `configure', and exit. The `short' variant lists options used
- only in the top level, while the `recursive' variant lists options
- also present in any nested packages.
-
-`--version'
-`-V'
- Print the version of Autoconf used to generate the `configure'
- script, and exit.
-
-`--cache-file=FILE'
- Enable the cache: use and save the results of the tests in FILE,
- traditionally `config.cache'. FILE defaults to `/dev/null' to
- disable caching.
-
-`--config-cache'
-`-C'
- Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
- Do not print messages saying which checks are being made. To
- suppress all normal output, redirect it to `/dev/null' (any error
- messages will still be shown).
-
-`--srcdir=DIR'
- Look for the package's source code in directory DIR. Usually
- `configure' can determine that directory automatically.
-
-`--prefix=DIR'
- Use DIR as the installation prefix. *Note Installation Names::
- for more details, including other options available for fine-tuning
- the installation locations.
-
-`--no-create'
-`-n'
- Run the configure checks, but stop before creating any output
- files.
-
-`configure' also accepts some other, not widely useful, options. Run
-`configure --help' for more details.

-Iscsiuio Userspace Tool
-Version 0.7.8.6
-Jun 27, 2019
-------------------------------------------------------
-
-This tool is to be used in conjunction with the QLogic NetXtreme II Linux
-driver (Kernel module name: 'bnx2' and 'bnx2x'), QLogic CNIC driver,
-and the QLogic iSCSI driver (Kernel module name: 'bnx2i').
-This user space tool is used in conjunction with the following
-QLogic Network Controllers:
- bnx2: BCM5706, BCM5708, BCM5709 devices
- bnx2x: BCM57710, BCM57711, BCM57711E, BCM57712, BCM57712E,
- BCM57800, BCM57810, BCM57840 devices
-
-This utility will provide the ARP and DHCP functionality for the iSCSI offload.
-The communication to the driver is done via Userspace I/O (Kernel module name
-'uio').
-
-There is one component to this application:
-
-1. 'iscsiuio' - This is the daemon which aids in creating iSCSI offloaded
- connections.
-
-Dependencies:
-=======================================
-
-Linux Kernel Dependencies:
-1. QLogic CNIC driver (cnic)
-1. QLogic iSCSI offload driver (bnx2i)
-2. Userspace I/O driver (uio)
-
-Directory Structure of this Package:
-=======================================
-
-<root>
- |
- +-doc (documentation directory: man pages)
- |
- +-src
- |
- +- uip - the uIP stack
- |
- +- unix - iscsiuio source
-
-
-
-Compiling / Installing
-=======================================
-
-1. Please untar the tarball.
-2. Run the configure script. This will create the Makefiles and proper
- header files needed for the build.
-3. Run 'make'. This will create the binary, 'iscsiuio'
-4. Run 'make install' to place the binaries in their installed location.
- (The default location is '/sbin')
-
-iscsid IFACE Configuration File:
-=======================================
-The network interface configuration files are driven by the iscsid iface
-files. The configuration data is parsed by iscsid and passed to the uIP
-stack when the connection is established.
-
-One can use the following iscsiadm commands to create/set the configuration
-using the iface files:
-
-1. Create the iface file:
-
- iscsiadm -m iface -I <iface name> --op=new
-
-2. Discover the targets associated with the new iface
-
- iscsiadm -m discovery -t st -p <iSCSI target IP address> -I <iface name>
-
-3. Update the iface file:
-
- To use a static IPv4 address:
- iscsiadm -m iface -I <iface name> --op=update --name=iface.ipaddress --value=<static IPv4 address ie: 192.168.0.1>
-
- To use a DHCP address:
- iscsiadm -m iface -I <iface name> --op=update --name=iface.ipaddress --value=0.0.0.0
-
- The following values are required.
-
- To specify the bnx2i as the transport:
- iscsiadm -m iface -I <iface name> --op=update --name=iface.transport_name --value=bnx2i
-
- To specify the network interface to offload with:
-
- a. Specify the physical network interface name <ie. eth0, eth1, eth2 ...>
- iscsiadm -m iface -I <iface name> --op=update --name=iface.net_ifacename --value=<network interface name>
-
- b. Specify the iSCSI MAC address of the iSCSI HBA
- iscsiadm -m iface -I <iface name> --op=update --name=iface.hwaddress --value=<MAC address of the iSCSI HBA>
-
-4. Now all the settings should be set so that one could connect to their
- desired iSCSI target.
-
- iscsiadm -m node -p <iSCSI target IP address> -T <target name> -I <iface name> --login
-
-bnx2 Limitations:
-=======================================
-* RX iSCSI ring:
- * default ring size is 3 entries
- * default buffer size is 0x400 bytes
-* TX iSCSI ring:
- * default ring size of 1 entry
- * default buffer size is 0x400 bytes
-
-bnx2x Limitations:
-=======================================
-* RX iSCSI ring:
- * default ring size is 15 entries
- * default buffer size is 0x400 bytes
-* TX iSCSI ring:
- * default ring size of 1 entry
- * default buffer size is 0x400 bytes
-
-Other Limiations:
-
-Any packets larger then the buffer size will not be sent/received by the
-hardware and will be dropped.
-
-IPv6 support:
-
-IPv6 NDP (neighbor discovery protocol), DHCPv6 and Static IPv6 are now
-supported. The IPv6 address used for the connection will be matched against
-the DHCPv6/static IPv6 address, the RA (router advertise) address, and the
-assigned link local address.
-
-VLAN support:
-
-VLAN support is only supported when using static IP addresses.
-Also, currently only 1 VLAN is supported per physical network interface.
-Either non-VLAN offloaded traffic is allowed or VLAN offloaded traffic
-is allowed. The current implementation does not support both at the
-same time.
-
-Currently there is no explicit VLAN attributes in the iface file.
-To configure the VLAN offload, the iface.hwaddress attribute or
-physical net_ifacename (without the VLAN identifier) must be used
-to specify the HBA device. For the proper CNIC routing, the
-corresponding L2 interface which has the associated VLAN interface must
-have an IP address on the same subnet.
-
-The following attributes need to be filled when offloading via the
-VLAN interface:
-
- iface.iscsi_ifacename = <name of this iface file>
- iface.hwaddress = XX:XX:XX:XX:XX:XX
- iface.ipaddress = XX.XX.XX.XX
- iface.transport_name = bnx2i
-
-Setting IP address:
-
-On RHEL5.4, RHEL5.5+, RHEL6.0+, and SLES11SP1 distributions,
-discovery login is done over the Linux TCP/IP stack and L2 network
-interface. The ethx interface corresponding to the HBA must
-therefore be in the same IP subnet in order to reach the iSCSI
-target during discovery. However, the HBA's IP address should not
-be the same as the L2 ethx's IP address.
-
-Starting with RHEL6.1 and all other newer distributions, discovery
-using SendTargets is done over the HBA interface, so there is no
-need for the HBA and L2 network to be on the same subnet. However,
-if VLAN is used on the HBA, they still have to be on the same subnet
-as described above.
-
-
-Setting Netmask and Gateway addresses:
-
-With the current limitations of the iface file, there are no entries
-to allow the user to enter a netmask or gateway IP address.
-
-The only way to explicitly configure these options is to use DHCP
-addressing. Then the netmask/gateway are set on the DHCP server.
-These settings are then sent to uIP via the DHCPOFFERs.
-
-If the netmask is not defined then the netmask are automatically
-generated depending on the destination IP address.
-
-Debugging:
-=======================================
-
-By default, the iscsiuio daemon does not output any messages to the log file,
-'/var/log/iscsiuio.log'. Message logging is only enabled when the daemon is
-run under debug mode.
-
-To run the daemon in debug mode please pass the parameter '-d <debug level>'
-
-where the following debug levels are defined:
-
-DEBUG 4 - Print all messages
-INFO 3 - Print messages needed to follow the uIP code (default)
-WARN 2 - Print warning messages
-ERROR 1 - Only print critical errors
-
-A sample banner message:
-
-INFO [Mon Jun 20 11:23:14 2011]Started iSCSI uio stack: Ver 0.7.0.6
-INFO [Mon Jun 20 11:23:14 2011]Build date: Mon Jun 20 11:22:05 PDT 2011
-INFO [Mon Jun 20 11:23:14 2011]Debug mode enabled
-
-These messages can be used to help debug any issues.
-
-When debugging issues like the iscsid, the iscsiuio daemon can be run
-in the foreground and the maximum debugging level should be used.
-
-To place the daemon in foreground mode please pass the parameter '-f'
-
-Note: The messages to the log file are not flushed unless debugging is enabled.
-
-Note: If the daemon iscsiuio is running, one will not be able to
- trample over the existing binary. One might see the following message:
-
- 'cannot create regular file `/sbin/iscsiuio': Text file busy'
-
- The solve this, please stop the iscsid service and then install.
-
-Warning: If full debug is enabled, this may quickly fill the partition
-containing the iscsiuio logs. This is because full debugging will log
-packet activity which on a busy network will quickly fill the logs.
-
-Note: If the bnx2i and cnic drivers are unloaded, then iscsiuio will also
-need to be restarted so that it can determine the iscsid version.

-=======================================================
- Fixes:
- -------
- 1. Problem: OS fails to boot after one path is
- disconnected from iSCSI MPIO config.
- Change: In the event of DHCP failure, killing of enable_nic_thread did
- not process any iscsid requests leading to error,
- iscsistart: Could not broadcast to uIP after 5 tries
- and login failure of active path.
- Added fix to not kill enable_nic_thread and allow further
- processing of iscsid requests and performing login
- to next active path.
- Impact: All

-=======================================================
- Fixes
- -----
- 1. Problem: Cont00065768 - RHEL5.X iscsiuio segfault possible
- if there is a specific 1024 byte size broadcast
- packet
- Cause: This is another corner case where the packet size
- is also exactly 1024 bytes + padding that exceeded
- the DMA rx buffer. The previous fix was not
- sufficient
- Change: Ensure that the packet size + padding do not
- exceed this limit.
- Impact: 10G only. 1G already has the guard against it.
-

- tagged vlan with IPv6 failed
- Cause: The new net param support changes has prevented
- the old vconfig method from execising the IPv6
- acquisition engine properly
- Change: Ensure that this old vconfig method to run the IPv6
- acquisition engine properly and to its entirety
- Impact: IPv6 + VLAN using the network VLAN configuration
- method
-
- 2. Problem: Cont00065768 - RHEL5.X iscsiuio segfault possible
- if there is a specific 1024 byte size broadcast
- packet
- Cause: This is a corner case where the packet size is
- exactly 1024 bytes + padding that exceeded the
- DMA rx buffer. This has been there since day 1.
- Change: Ensure that the packet size + padding do not
- exceed this limit.

- Impact: 577XX/578XX
-
-
-uIP v0.7.4.2j (Jul 18, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00064665 - Linux iSCSI connects via gateway address
- on the wrong subnet
- Cause: The gateway address used was not checked against the
- subnet mask specified before the ARP requests. Since
- this behavior deters from how L2 operates, therefore,
- a change was made to correct this.
- Change: Added check of the gateway specified against the subnet
- specified.
- Impact: Static IPv4 operation
-
- 2. Problem: Cont00064722 - Linux iSCSI unable to force IPv6 LL
- override (advanced iface parameters)
- Cause: The override LL address was not being populated to the
- IPv6 address database correctly
- Change: Added this correctly to the IPv6 initialization
- Impact: Static/DHCP IPv6 LL address override only
-
-
-uIP v0.7.4.2i (Jul 11, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00064604 - Fails to connect to routed IPv6 target
- via RA
- Cause: The default router IPv6 address was not being retrieved
- correctly.
- Change: Fixed the default router IPv6 address read
- Impact: All
-
-
-uIP v0.7.4.2h (Jun 15, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00063863 - can't boot into offload image
- when VLAN is enabled
- Cause: During the iSCSI login exchange, certain iSCSI targets
- will send an ARP request even though the TCP connection
- has been made. The bug was in this ARP reply where
- the local MAC was corrupted when VLAN is enabled.
- Change: Fixed the ARP reply packet
- Impact: All
-
-
-uIP v0.7.4.2g (Jun 08, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00063816 - The initiator is not able to connect
- to the iSCSI targets over VLAN
- Cause: The process packet routine did not consider the PCP
- of the VLAN tag to be non-zero. This created a
- mismatch when this VLAN tag was compared against the
- nic_iface->vlan_id which doesn't include the PCP.
- Change: Added the consideration of non-zero PCP
- Impact: All
-
-
-uIP v0.7.4.2f (Jun 04, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00063626 - Static IPv6 does not connect when
- the prefix len is not set explicitly
- Cause: The IPv6 prefix length was not set correctly
- for Static IPv6 operation when CIDR notation is
- not specified
- Change: Fixed the default prefix length
- Impact: Static IPv6
-
- 2. Problem: Cont00063651 - Cannot connect to iSCSI targets
- HP PTM/SF
- Cause: Switch-Dependent mode + invalid Outer VLAN was
- not supported
- Change: Allow SD+invalid OV to fallback to SF operation mode
- Impact: 5771X/578XX
-
-
-uIP v0.7.4.2e (May 30, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00063443 - Compilation error on SLES11sp1
- Cause: The iface_num field was not defined
- Change: Fixed all references to iface_num
- Impact: SLES11sp1
-
- 2. Problem: Cont00063518 - HBA fails to connect across router
- using iface.gateway address
- Cause: The gateway override code did not populate the
- address into the lower level engine
- Change: Fixed the gateway override code
- Impact: IPv4 Static IP operation
-
- 3. Problem: Cont00063567 - IPv6 LL and RA override does not work
- Cause: The IPv6 LL/RA override addresses were overwritten
- by the NDP engine
- Change: Fixed the LL/RA override code
- Impact: IPv6 operation
-
- Enhancements
- ------------
- 1. Added support for jumbo MTU (independent from the L2 MTU)
-
-
-uIP v0.7.4.2d (May 21, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00063421 - Static IPv6 cannot connect via RA/LL
- Cause: The router advertise and the linklocal address
- were corrupted due to the override capabilities
- added for the newer open-iscsi util
- Change: Fixed the address override code
- Impact: Static IPv6
-
- Enhancements
- ------------
- 1. Allow VLAN tag = 1 (router management) to connect offload
-
-
-uIP v0.7.4.2c (May 09, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: RHEL BZ 734010/804580 - issues found by the Coverity
- scan
- Cause: 10 code issues were flagged for revision
- Change: Fixed all area of concern
- Impact: All
-
- 2. Problem: Cont00063177 - IPv4 DHCP with VLAN specification in
- iface file gets wrong address
- Cause: The DHCPv4 handler was not discriminating the VLAN tag
- associated with the DHCP offers from multiple DHCP
- servers
- Change: Changed the DHCPv4 handler to drop DHCP offer packets
- that doesn't match the VLAN tag of the intended DHCP
- discovery packet
- Impact: DHCPv4 operation
-
-
-uIP v0.7.4.2b (May 01, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00062993 - IPv6 DHCP with VLAN specification in
- iface file gets wrong address
- Cause: The DHCPv6 request was using the same DUID as always
- so the non-VLAN DHCP server responded to our broadcast
- instead
- Change: Changed the DHCPv6 request DUID to link address + time
- instead of link address alone
- Impact: DHCPv6 operation
-
-
-uIP v0.7.4.1j (Apr 24, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00062805 - Cannot login to iSCSI targets on RHEL6.3
- Cause: The problem was caused by a change made to the iface_rec
- structure in the RHEL6.3 inbox open-iscsi util
- Change: The new changes is now incorporated
- Impact: All
-
-
-uIP v0.7.4.1i (Apr 16, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00062660 - Unable to login with VLAN iscsiuio
- on RHEL6.2
- Cause: The open-iscsi util in RHEL6.2 has a bug which
- does not pass the correct iface_num to iscsiuio
- Change: Added workaround to fall back to do the legacy
- VLAN support if iface_num and vlan_id = 0
- Impact: RHEL6.2
-
-
-uIP v0.7.4.1h (Apr 13, 2012)
-=======================================================
- Enhancements
- ------------
- 1. Added support for the new iface_num field in the iscsi_uevent
- path
-
- 2. Fixed bug in the nic_iface search engine based on iface_num
-
-
-uIP v0.7.4.1g (Mar 22, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00061869 - Unable to setup an offload iSCSI
- connection with FLR/NPAR under ESX5.0:PDA
- Cause: The physical function ID was previously extracted
- from the sysfs of the VM which might not be consistent
- to the actual physical setup due to the function
- remapping in the hypervisor
- Change: Read the physical function ID directly from the BAR0
- ME register
- Impact: All
-
- 2. Problem: Cont00062170 - IPv6 login/logout stress fails
- Cause: The packet interrupt was lost after running the test
- for a much longer period of time. A bug in the
- packet processing routine was found to exit prematurely
- Change: Fixed the packet processing routine to process all
- packets before exiting
- Impact: All
-
-
-uIP v0.7.4.1f (Mar 19, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00062170 - IPv6 login/logout stress fails
- Cause: The packet buffer routine for IPv6 did not take
- network order <-> host order into consideration
- Change: Added a htons call to compensate for the ntohs pair
- Impact: All
-
-
-uIP v0.7.4.1e (Mar 08, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00061978 - Load/unload stress test fails
- Cause: The bnx2x open request was failing due to the module
- request procedure. However, the open failure was
- not being handled correctly.
- Change: Fixed the device open error handling
- Impact: 5771X/578XX
-
-
-uIP v0.7.4.1d (Mar 02, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00061708 - Unable to log into target after running
- driver load/unload
- Cause: A bug was introduced in the previous bug fix (CQ61459)
- where a pthread_cond_broadcast call was erroneously
- enabled
- Change: Restored this back
- Impact: All
-
-
-uIP v0.7.4.1c (Feb 16, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00061529 - Unable to connect to target after an
- initial failed login attempt until iscsi service is
- restarted
- Cause: Upon a failed DHCPv4 acquisition due to the wrong VLAN
- tag in the initial iface setup, any iscsid connect request
- from the same NIC will get dropped due to a bug.
- Change: Fixed the bug which prevented new iscsid connect requests
- from getting honored
- Impact: All
-
- Enhancements
- ------------
- 1. Updated README
-
-
-uIP v0.7.4.1b (Feb 08, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00061513 - Unable to connect to target over VLAN
- interface
- Cause: The VLAN id was not properly passed back to the CNIC
- driver for the offload request
- Change: Fixed the VLAN id being passed back to the CNIC driver
- Impact: All
-
-
-uIP v0.7.4.1a (Feb 01, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00049383 - No mechanism in iface file to support
- gateway/routing
- Change: Added support for the additional network parameters
- as passed from the newer iscsi-util.
- These parameters include:
- IPv4: subnet_mask, gateway
- IPv6: ipv6_linklocal, ipv6_router,
- ipv6_autocfg, linklocal_autocfg, router_autocfg
- VLAN: vlan_id, vlan_priority, vlan_state
- Other: mtu, port
- Impact: All
-
- 2. Problem: Cont00060806 - Unable to connect target using DHCP over
- tagged VLAN
- Change: DHCP+VLAN is a new feature enhancement that was added
- alongside all other new iface parameters.
- Impact: All
-
-
- Enhancements
- ------------
- 1. Lock iscsid's connect request with path_req so connect requests
- with DHCP/Static will no longer override each other
-
- 2. Fixed the if_down handler from global to nic specific
-
- 3. Fixed various synchronization issues
-
-
-uIP v0.7.2.1e (Jan 05, 2012)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00060734 - ifupdown-mtu change stress with active
- session causes iscsiuio to fail
- Change: Fixed a race condition between the nic enable thread
- and when DHCP fails
- Impact: All
-
-
-uIP v0.7.2.1d (Dec 28, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00060368 - segfault observed after failing both
- mpio paths
- Change: Various memory leaks were identified and resolved in
- the nic cleanup path
- Impact: All
-
-
-uIP v0.7.2.1c (Dec 16, 2011)
-=======================================================
- Enhancements
- ------------
- 1. Change: Disable HP SD mode
-
-
-uIP v0.7.2.1b (Dec 14, 2011)
-=======================================================
- Enhancements
- ------------
- 1. Change: Default iscsiuio logging to off. Use the '-d'
- option to enable
-
-
-uIP v0.7.0.14g (Oct 25, 2011)
-=======================================================
- Enhancements
- ------------
- 1. Change: Fixed the compilation under RHEL6.2
- 2. Change: Added oom_adjust call to prevent OOM Killer from killing
- iscsiuio when memory is low
- 3. Change: Added mlockall setting to prevent page swap
-
-
-uIP v0.7.0.14f (Oct 20, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00058994 - DOS vulnerability in uip during UDP flood
- Cause: The warning messages from the UDP handler was logging
- at a rate faster than the log file logrotate rate
- Therefore, the system's OOM eventually got kicked in to
- start terminating running processes which includes iscsiuio
- Change: Moved several UDP warning messages from the default log
- level to the debug log level
- Impact: All (minor)
-
- 2. Problem: Cont00059288 - Show segfault w/ SLES11 SP1 Xen kernel
- Cause: The bnx2x chip_id was not read correctly from the PCIe BAR1
- under the Xen kernel. The error was in the mmap area.
- Change: Corrected the mmapping of the PCI MMIO space.
- Impact: Xen kernels
-
- Enhancements
- ------------
- 1. Change: Changed the log file open error to a warning and let
- the daemon progress. This was only observed under iSCSI boot
-
-
-uIP v0.7.0.14e (Sep 19, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00058678 - Can not iboot target from ipv6 path
- using VLAN
- Cause: A bug was found in the path request path where the vlan
- iface's protocol family was not used correctly in the
- iface search
- Change: This has been corrected
-
-
-uIP v0.7.0.14d (Sep 16, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00058602 - Can't iboot using IPv6 offload path
- Cause: The bug was exposed by a fix in 0.7.0.14c where the
- IPv6 router solicitation timeout exceeded the nic
- enable thread timeout.
- Change: The IPv6 router solicitation timeout has been adjusted
-
-
-uIP v0.7.0.14c (Sep 01, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00058256 - Sessions fail after loginstress to via
- simultaneous ipv4 and ipv6 dhcp
- Cause: Switching between DHCPv4/v6 coupled with VLAN exposed
- a drawback in our nic_iface architecture design where
- VLAN is not specified by iscsid.
- Change: The code was optimized and improved the performance when
- switching between DHCPv4/v6+VLAN. However, the ultimate
- fix is to make use of the net config parameters introduced
- in the newer open-iscsi util which will identify the
- specific VLAN nic_iface to use.
-
- Enhancements
- ------------
- 1. Change: Added support for bnx2x-1.71.00
-
-
-uIP v0.7.0.14b (Aug 23, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00057840 - RHEL6.2 inbox: Unable to connect to
- targets with 5709
- Cause: For cases when the bnx2/bnx2x driver gets removed, the
- uio database that was built by cnic would have the device
- ->net reference removed. This has caused an unnecessary
- timeout of 5s for each stale uio entry in the database.
- Change: Adjusted the routine which seeks the device->net entry
- to include more logic instead of hard waiting for 5s.
-
- Enhancements
- ------------
- 1. Change: Added support for RHEL6.2 for out-of-box release
- 2. Change: Updated the man page with -h and -p info
- 3. Change: Updated the -h info
-
-
-uIP v0.7.0.13 (Aug 10, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00057768 - iscsiuio logrotate causes daemon failure
- Cause: The logrotate script will send a SIGUSR1 signal to notify
- the iscsiuio daemon of such action. However, the daemon
- wasn't programmed to catch this signal.
- Change: Restored the catching of this signal
-
-
-uIP v0.7.0.12 (Aug 04, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00050634 - brcm_iscsiuio Tainted: running IoZone,
- Iometer and receiving a UDP flood on 3260
- Cause: Upon iscsiuio termination, because of the UDP flood,
- the nic thread will be busy servicing those UDP packets
- while the signal handling thread will free up all nic
- resources. The two threads were not in sync.
- Change: Added a nic_remove_all routine to destroy all nic threads
- before the nic resources get freed.
-
- Enhancements
- ------------
- 1. Change: Fixed all warnings as reported by RHELS' Coverity testing.
-
-
-uIP v0.7.0.11 (Aug 02, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Erroneous VLAN tag was being passed by iscsid for connect
- request
- Cause: The iscsid's iface_rec_t ipc message does not contain this
- vlan field. This field was added in uIP for future vlan
- support. Since the buffer allocated to receive such message
- in uIP didn't get initialized, therefore, garbled up VLAN
- tag was getting used.
- Change: Added the initialization of this buffer.
-
-
-uIP v0.7.0.10 (Jul 26, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Can't offload when switching from Static to DHCP then back to
- Static IPv4 when connecting through a VLAN interface
- Cause: The VLAN processing code did not reinstall the IP address
- from the default nic_iface to the associated VLAN nic_iface.
- This was only done on the very first time when the VLAN
- interface was created and not on subsequent instances.
- Change: Added code to mirror the default nic_iface IP/netmask/ip_config
- on the VLAN nic_iface on every new connection request.
-
-
-uIP v0.7.0.9 (Jul 19, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Can't offload to 57810 NPAR NIC
- Cause: The MF/VF variant of the PCI IDs were not supported previously
- Change: Added support for the MF/VF variants for 57800/57810/57840
-
-
-uIP v0.7.0.8 (Jun 30, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00056522 - Unable to connect to iSCSI target using
- netxtreme2 package 7.0.9
- Cause: The iSCSI L2 ring's CID has changed from 17 to 49
- Change: The code now gets L2 iSCSI ring CID from the l2_buf directly.
- This will work with any version of the cnic driver because
- the location is a zero before this change.
-
-
-uIP v0.7.0.7 (Jun 23, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00056460 - iSCSI Offload boot RHEL5u5 x64 dropped tagged
- packets with iSCSI Offload Boot with untagged
- Cause: The ICMP echo replies to the target was corrupted in both
- 1g and 10g mode
- Change: The code will now handle both VLAN stripped and no VLAN stripped
- incoming packets correctly. Also modified the transmit routine
- to strip out any inline VLAN tag before setting up the hw to
- insert VLAN tag.
-
-
-uIP v0.7.0.6 (Jun 21, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00056231 - DHCPv4 not working with iSCSI HBA w/
- linux-nx2 v7.0.7
- Cause: The 10g L2 FW HSI has been modified for PCIe performance
- enhancement in the 7.0.7 package (FW 1.70.20) which uIP
- has not adapted to.
- Change: The eth_rx_cqe size has been increased from 32B to 64B.
-
- Enhancements
- ------------
- 1. Change: The utility name has changed from brcm_iscsiuio to iscsiuio
- as preparation for upstream submission.
- 2. Change: Updated README
-
-
-uIP v0.7.0.5 (Jun 02, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00055915 - iSCSI does not connect on 57800 in 4-port mode
- Cause: The 4-port mode was not being determined correctly
- Change: Fixed the PORT4MODE register offset and the QZONE_ID macros
-
-
-uIP v0.7.0.4 (May 24, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00055832 - linux iscsiboot can not login to target using
- offload path (57800)
- Cause: The device ID comparison routine did not take care of the case
- when one device ID is bitwise superset of another.
- Change: Fixed the device ID comparison routine.
-
-
-uIP v0.7.0.3 (May. 19, 2011)
-=======================================================
- Enhancements
- ------------
- 1. Change: Updated all fixes to match the released uIP 0.6.4.17
-
- 2. Change: Modified source and Copyright info as preparation for upstream
- submission
-
-
-uIP v0.7.0.2 (May. 03, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00048972 - brcm-iscsi.log has no max size and would grow
- to consume all free space on hard disk
- Cause: There was no mechanism to rotate the log
- Change: Added logrotate entry and SIGUSR1 signal handling for log rotate
- action
-
- 2. Problem: Cont00054996 - Multi-session, multi-protocol mtu stress
- does not recover all sessions
- Cause: A segfault was observed during the load/unload module. The
- problem was caused by an illegal dereference of a pointer
- when IPv6 couldn't find the longest match address from
- the ARP (Neighbor) table.
- Change: Fixed the dereferencing error
-
- 3. Problem: Cont00054900 - Linux uIP - Please add ability to connect
- to routed target with static iface IPv6
- Cause: Static IPv6 never runs the IPv6 NDP router sol/adv engine.
- Change: IPv6 NDP router sol/adv has now been added to static IPv6
- operation.
-
- 4. Problem: Cont00054996 - Multi-session, multi-protocol mtu stress
- does not recover all sessions
- Cause: Segfaults were observed caused by the accessing of the IPv6
- NDP structure while the nic is undergoing a reset either
- due to a DHCPv4 request from iscsid or the handling of
- if_down due to the NL handler from CNIC.
- Change: The fix involves the following:
- - Fixed the handling of staggered IPv4/v6 DHCP/static requests
- - Fixed memory leak due to reallocation of IPv4 and IPv6
- DHCP structs
- - Fixed the pthread join stuck problem in the handling
- of the if_down NL message
-
- 5. Problem: Cont00054810 - Linux NMI - bnx2x_init_hw_common:PXP2 CFG
- failed running iSCSI MTU stress test
- Cause: This only happens in DHCPv4 mode. The problem was caused
- by contention between the elongated window of performing
- DHCP in the enable_nic thread while receiving the asynchronous
- if_down NL message (from the MTU change event) from the
- CNIC NL thread. The problem occurs when the enable_nic
- thread tries to call bnx2x_open while the other thread
- calls the bnx2x_close routine.
- Change: Fixed mutex lock bugs for the enable_nic thread. Also
- extended the nic_disable timeout to 10s to compensate for
- the DHCP operation.
-
- 6. Problem: Cont00054818 - RH6.0 - Unable to logout of iSCSI session
- after running PQA baseline scripts
- Cause: This was caused by the call to cancel the enable_nic
- thread when disabling the nic but failed to unlock the
- nic mutex that the enable_nic thread held.
- Change: Wake up the enable_nic thread and wait for it to complete
- instead of canceling it in the nic_disable path.
-
- 7. Problem: Cont00054725 - Previous static HBA IP will be used after
- a new static HBA IP has been created
- Cause: There was an assumption in the code where if the same
- nic_iface structure was found based on the nic/vlan pair,
- the specified IP address would not be used. Instead, it
- will continue to use the previous defined IP address.
- Change: The previous IP address will now be compared against the
- the specified IP address before finishing the parce
- iface request from iscsid. If different, the current
- nic will be disabled and then re-enabled with the newly
- specified IP address.
-
- 8. Problem: Cont00054571 - Unable to connect to routed ipv6 target
- with RA address and iface DHCPv6
- Cause: The default router address was not being employed for
- the IPv6 neighbor negotiation. Additionally, the return
- address of our neighbor advertisement was incorrect as
- it should use the best matched src address instead.
- Change: Fixed both the IPv6 neighbor solicitation and advertisement
- transmission and handling.
-
- 9. Problem: Cont00054510 - fails to login to 32 session with blanket
- login IPv6
- Cause: A bug was introduced in uIP 0.6.4.6 where the NIC_RUNNING
- flag might not be set when entering the main loop under
- certain situations depending on the nic bring up.
- Change: A new NIC_STARTED_RUNNING flag is now defined to fix CQ53511.
-
- 10. Problem: Cont00053807 - RA and link local are unable to connect if DHCPv6
- fails
- Cause: The host link local address was not being searched as one of
- the host address to be replied to CNIC for the connect request.
- Change: The path reply now includes the search of host link local
- address as well.
-
- 11. Problem: Cont00054236 - iSCSI service must be restarted before an IPv6
- connection can be made to the Equalogic target
- Cause: The problem was intermittent as it depends on which IPv6 address
- the target was redirecting to. Since uIP was only extracting
- the target's IPv6 address + MAC from the target's neighbor
- advertisement packet itself and not from the ICMPv6 option, so
- the wrong or no MAC address will get send down to CNIC for the
- connection establishment; hence the no connect.
- Change: Added the updating of the neighbor discovery table to also use
- the Target IPv6 address + MAC specified in the incoming neighbor
- advertisement's ICMPv6 option field.
-
- 12. Problem: Cont00053255 - bnx2x panic dump logging into multiple
- discovered IPv6 nodes (Equalogic IPv6 target)
- Cause: The bnx2x panic was fixed in the 10g fw 6.4.29.
- A IPv6 connectivity issue was then found and led to different
- kernel/uIP crashes. This was caused by the same IPv6
- connectivity problem mentioned above.
- Change: Same as above
-
- 13. Problem: Cont00053728 - Sessions never recover after doing initiator-side
- cable pull test with IPv6 traffic against Equalogic targets
- Cause: It was discovered that the Equalogic would send out periodic
- neighbor solicitation to maintain the connection to the
- initiator. Since uIP was responding with the assigned IPv6
- link local address in the neighbor advertisement
- unconditionally, the target was observed to stop transmitting on
- the connection specified.
- Change: The neighbor advertisement generated will now use the dst IPv6
- address from the input neighbor solicitation packet instead of
- the assigned IPv6 link local address for both the packet and the
- ICMPv6 source IPv6 address.
-
- 14. Problem: Compile error under 32-bit OS
- Cause: A bug was introduced in the previous release 0.6.4.6 which
- caused a compilation error in 32-bit OS (64-bit compiles
- fine)
- Change: Fixed the bug
-
- 15. Problem: Cont00053807 - RA and Link local are unable to connect if dhcpv6
- fails
- Cause: There was a bug in the nl reply where the RA address will never
- be sent back to CNIC for the connection request
- Change: The best matched address to the dst will now be sent back to
- CNIC in the path rsp.
-
- Enhancements
- ------------
- 1. Change: Updated README to remove the 57713/E references
-
- 2. Change: Allow the ICMP option field in the IPv6 Neighbor Advertisement
- response to be included without discrimination. This fixes
- an issue connecting against the EQL via RA for DHCPv6.
-
- 3. Change: Updated README for the IPv6 operation, VLAN, and discovery.
-
-
-uIP v0.7.0.1 (Mar. 29, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00053511 - bnx2x panic dump during ifup/down stress with
- iSCSI traffic
- Cause: The panic dump was resolved by the driver's rq dbell size fix.
- After that, uIP crashed due to the asynchronous if_down event
- that took the chip resources away while the nic thread is still
- continuing to try to send DHCP request.
- Change: Added synchronization between the two threads so proper clean up
- of the threads can occur.
-
- Enhancements
- ------------
- 1. Change: Added support for E3 (57800, 57810, and 57840)
-
-
-uIP v0.6.4.5 (Mar. 23, 2011)
-=======================================================
- Enhancements
- ------------
- 1. Change: Optimized the double VLAN fix of CQ53870 to match
- what will be submitted for RHELS5.7 and RHELS6.1 inbox
-
-
-uIP v0.6.4.4 (Mar. 17, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00053870 - Unable to login to iSCSI target via offload
- through a Nexus 5020 switch with DCBx enabled
- Cause: Double VLAN tagging was observed due to DCBx enabled.
- The chip actually adds a VLAN tag if the txbd does not have
- VLAN tag enabled under the DCBx environment for PRI setting.
- Since uIP does not make use of hw assisted VLAN tagging,
- 2 VLAN tag was observed in the data stream.
- Change: Enabled hw assisted VLAN tagging in uIP for both 1g and 10g.
-
- 2. Problem: Cont00053792 - maxconnections intermittently fail and
- recover using iface DHCPv4
- Cause: The DHCPv4 engine erroneously keeps on requesting for a
- new lease which tremendously hamper normal path_req
- operation. The problem is that the lease time parameter
- has overflowed when converted to ticks count.
- Change: Expanded the lease timer ticks count parameter from 16 to
- 32 bits.
-
- 3. Problem: Cont00053807 - RA and link local are unable to connect if
- DHCPv6 fails
- Cause: The DHCPv6 engine does not have the failover to use RA
- mechanism
- Change: Expanded to use best match address instead regardless of
- DHCPv6 success or not, or using static v6.
-
- Enhancements
- ------------
- 1. Change: Cont00051823 - Added man page for brcm_iscsiuio
-
-
-uIP v0.6.4.3 (Mar. 15, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00053719 - intermittent logging into targets that
- are not in the same subnet as defined in the iface
- Cause: The default route was used erroneously due to a miscompare
- Change: Fixed this comparison so if the requested dst is not in
- in the same subnet, uIP would not even ARP out.
-
- 2. Problem: Cont00053580 - Unable to do iSCSI boot into Linux OS using
- 57710 adapters
- Cause: The E1 iro USTORM_RX_PROD_OFFSET doesn't match the t6.4 fw
- Change: This is now fixed
-
-
-uIP v0.6.4.2 (Feb. 24, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00050343 - HBA does not follow RFC2131 spec for IPv4
- DHCP lease expiration
- Cause: The dhcp engine did not have this feature implemented
- Change: Added lease time tracking and renewal
-
- 2. Problem: Cont00050801 - Unable to connect to target after switching
- between DHCPv4 to static v4
- Cause: The configuration flags got corrupted when switching between
- dhcp and static or vice versa.
- Change: Fixed the flag handling. Also needed to zero out the static
- ip address in the host memory when switching to dhcp.
- Otherwise, the static ip address will get used mistakenly.
-
- Enhancements
- ------------
- 1. Change: Cont00051936 - Added IPv6 NDP and DHCPv6 support.
-
-
-uIP v0.6.4.1 (Jan. 27, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00049766 - segfault seen while stopping iscsi service
- Cause: The logger output routine was accessing the log resource
- while another thread calls fini_logger to free the same
- resources
- Change: Added pthread mutex lock to the logger routine to exclude
- the initializer, user, and finisher
-
- Enhancements
- ------------
- 1. Change: Added new t6.4 HSI and 57713 support.
-
-
-uIP v0.6.2.13 (Jan. 04, 2011)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00049665 - iscsiboot:linux failed to boot into iscsi
- boot image in offload path after 5 iterations
- Cause: The hw consumer index for the uIP ring got out of sync
- with the producer index. This has led to the xmit mutex
- lock be held forever so subsequent ARP requests will not
- get transmitted to the wire
- Change: Added this out of sync detection and rescue the xmit mutex
- lock
-
-uIP v0.6.2.12 (Dec. 21, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: Cont00051820 - Session fails to reconnect after gateway
- fallback
- Cause: Under the HSRP test scenario, it was found that an ARP
- request from the SUT is required in order for the HSRP
- router to begin sending packets downstream to the SUT.
- The default ARP age was originally set to 20 minutes
- before a new ARP request will get sent,
- Change: Changed the ARP age default to Linux default at 5 minutes
-
-uIP v0.6.2.11 (Dec. 17, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: For IPv4, the gateway route was not being utilized
- when the subnet mask given or calculated does not
- match. This resulted in many unwanted connection
- attempts.
- Cause: A bug was found in the default gateway calculation
- logic which prevented the gateway address from being
- used.
- Change: Fixed the default gateway logic
-
- 2. Problem: For IPv6, there are scenarios where it won't connect
- Cause: The IPv6 subnet mask as extracted from the CIDR
- format might contain garbage data. This garbage data
- was then used as part of the subnet mask which would
- prevent the correct address mask.
- Change: Fixed the subnet mask
-
-uIP v0.6.2.10 (Dec. 15, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: IPv6 does not connect for non-CIDR iface.ipaddress
- specification
- Cause: A bug where all ones was used as the IPv6 netmask
- instead of all zeroes. This prevented all IPv6
- path requests from being honored
- Change: Fixed the subnet mask used
-
-uIP v0.6.2.9 (Dec. 14, 2010)
-=======================================================
- Enhancements
- ------------
- 1. Change: Added IP address CIDR notation support for the
- iface.ipaddress field in the iface file.
- This will allow subnet mask to be defined and used.
-
-uIP v0.6.2.8 (Dec. 9, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: ipv6 + ifup/down fails to reconnect
-
- Cause: There were 2 problems found:
- - the xmit_mutex lock was being held indefinitely
- - the nl_process_if_down flag for 10g doorbell ringing
- did not get reinitialized
-
- Change: Fixed the xmit_mutex deadlock via trylock
- Added nl_process_if_down initialization in the IF_DOWN
- process
-
- 2. Problem: Added fix for the NPAR disabled for 57712
-
- Cause: The mac address was not handled correctly
-
- Change: Fixed the mac address handling. Also requires corresponding
- kernel component for the complete fix
-
-uIP v0.6.2.7 (Dec. 7, 2010)
-=======================================================
- Enhancements
- ------------
- 1. Change: Use the gateway address from the DHCP server the
- destination IP address is not in the current subnet.
-
-uIP v0.6.2.6 (Nov. 16, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: Warning message seen in the kernel logs,
- "uio uio2: uevent: unsupported action string"
-
- Cause: The improper string was echo'ed into the UIO trigger
- field. With an improper string, this message would
- appear in the kernel logs.
-
- Change: uIP will now write the string "online" to the UIO
- trigger field. This is the string expected by the
- Linux kernel base driver.
-
- 2. Problem: uIP would segfault during a heavily login/logout
- iSCSI subsystem reset senario
-
- Cause: A double free occurred in the logging portion of the
- uIP code, but this was root cause to a double free when
- manipulating the NetLink buffers.
-
- Change: Properly look at the return code from the routine which
- will read NetLink messages. Also only free buffers
- if they are allocated.
-
- Enhancements
- ------------
- 1. Change: Add ability to print kernel version and machine
- architecture to further help debug problems.
-
- 2. Change: Apply the netmask from DHCP if provided.
-
-uIP v0.6.2.5 (Nov. 10, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: iscsid would try to conenct with unintended iSCSI
- targets
-
- Cause: uIP would blindly return the iSCSI target MAC address
- regardless if the iSCSI target is reachable via the
- given port.
-
- Change: uIP will try to filter the requests coming from CNIC
- by automatically generating a network mask based off
- the configured IP addressed. Then this netmask is
- masked with the destination IP address. If there is
- a match, then the path_req is allowed through.
-
- 2. Problem: Problems reconnecting back to the target when running
- MTU stress tests.
-
- Cause: cnic/bnx2i and uIP could possibly get out of sync when
- an if_down message is sent.
-
- Change: uIP will now immediately react to the if_down message,
- and flush all the path req's and then to process to
- if_close.
-
- Enhancements
- ------------
- 1. Change: Fix compile warnings for src/unix/nic_nl.c,
- and src/unix/main.c
-
-uIP v0.6.2.4 (Nov. 4, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: iSCSI HBA: brcm_iscsiuio segfault during ifdown
- with many active sessions
-
- Cause: uIP will segfault when traversing the error path when
- an iSCSI connection is starting but the sysfs entries
- have not been created yet.
-
- Change: Use the errno value rather then the one from the file
- descriptor because the file descriptor will be NULL and
- the NULL dereference will cause a segfault.
-
- Enhancements
- ------------
- 1. Change: Added initial changes for iSCSI multi-function support for
- 10G NIC's.
- 2. Change: Add more detailed messages for error pathes in nic_utils
-
-uIP v0.6.2.3 (October 28, 2010)
-=======================================================
- Enhancements
- ------------
- 1. Change: Add support for bnx2x-1.62.x drivers
-
-uIP v0.6.2.2 (October 18, 2010)
-=======================================================
- Enhancements
- ------------
- 1. Change: Only allow iSCSI connections with known bnx2x HSI's.
-
-uIP v0.6.2.1 (October 7, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: After multiple MTU changes, the ethtool IOCTL used to
- determine the bnx2x driver version fails and eventually
- iSCSI connections would not reconnect.
-
- Cause: The socket file descriptor used during the ethtool IOCTL
- call was never closed and leaked.
-
- Change: On the error path when calling the ethtool IOCTL, the
- file descriptor is now properly closed.
-
-uIP v0.5.39 (September 15, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: Could not offload IPv4 VLAN connection when the target tries
- to ARP the iSCSI initiator
-
- Cause: In the ARP reply, the ether field was incorrect.
-
- Change: Properly set the ether field to 802.1Q type (0x8100)
-
-uIP v0.5.38 (September 14, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: uIP would cause a panic dump when the NIC was going down
-
- Cause: uIP and CNIC where not synchonized on NIC state
-
- Change: Check if the RX BD's which are zero'ed by CNIC when the
- NIC is going down. If the BD addresses are zero, then
- uIP will drop the TX packets.
-
-uIP v0.5.37 (August 21, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: uIP would segfault on ifup/ifdown stress test when using
- DHCP to determine local IP address.
-
- Cause: The uIP would use a NULL buffer during data transmission.
-
- Change: Drop packets when there are no buffer avaliable.
-
-uIP v0.5.36 (August 21, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: iSCSI boot would not completely login after the pivot
- root operation.
-
- Cause: The uIP would not properly start the NIC interface.
-
- Change: uIP should only check the NIC state to determine whether
- to start the NIC thread or not.
-
- 2. Problem: uIP would segfault during if'up if'down testing.
-
- Cause: The uIP would improperly start 2 NIC threads for the
- same NIC interface.
-
- Change: uIP should properly lock the NIC list when disabling/removing
- the NIC threads.
-
-
-uIP v0.5.35 (August 20, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: Sessions would hang with ethtool self-test
-
- Cause: The uIP would hang because the socket layer was stuck
- because there is much contention for that socket. This
- would hang the CNIC thread.
-
- Change: Remove any IOCTL calls in uIP which may colide with
- the ethtool self test. The driver version is only
- capture during uIP initialization.
-
- 2. Problem: There were session recovery issue when using DHCP
- if up/down tests.
-
- Cause: The uIP would hang because the DHCP requests would
- timeout if the network interface is downed which would
- hang all the other uIP threads.
-
- Change: Ensure that the DHCP state machine had exit points
- if the network interface was down'ed.
-
-
-uIP v0.5.34 (August 18, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: Sessions would not recover with ethtool self-test
-
- Cause: The uIP would hang because either the NetLink buffer is
- full or that any socket operations used to manipulate
- multicast addresses would block.
-
- Change: Ensure that the socket used for multicast addressing is
- set to nonblocking. Drain the NetLink buffer without
- using the eventing, but with a more aggressive poll routine.
-
- 2. Problem: Sessions would not recover with L2 driver load/unload on
- RHEL 6.0 SS9
-
- Cause: The uIP would close the NIC thread too early and would
- deadlock on cloing the NIC thread.
-
- Change: Ensure that the NIC thread is canceled/closed only in one
- location, in the NIC remove routine.
-
-
-uIP v0.5.33 (August 17, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: Error message seen from the uIP stack for valid packets.
-
- Cause: The uIP was incorrectly marking logging messages for valid
- packets as errors because it didn't know how to parase them.
-
- Change: Changed the following from error to debug message
- ipv6: invalid version
- ipv4: invalid version or header length.
- icmpv6: unknown ICMP message.
- ip: neither tcp nor icmp
- Changed the following from error to warn message
- udp: bad checksum
- tcp: bad checksum
- tcp: got reset, aborting connection.
-
- 2. Problem: After multiple iterations the loading and unloading of
- the Broadcom Linux drivers with active connections
- would not cause the sessions to recover on RHEL 6.0
- snapshot 9.
-
- Cause: There was a deadlock in the nic mutex
-
- Change: Lock ordering for the nic mutex and nic list mutex must
- be inforced.
-
- 3. Problem: After multiple iterations of running the ethtool selftest
- the Broadcom Linux drivers with active connections
- would not cause the sessions to recover on RHEL 5.5.
-
- Cause: The Netlink buffer between uIP and CNIC would get full.
-
- Change: Poll more regularly for packets in the Netlink buffer
- from 4 times a second to 100 times a 1 second.
- Drain packets during the PATH_REQ packet pull.
-
-
-uIP v0.5.32 (August 14, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: Error message 'nic eth0: Didn't find type 0xaa bb' seen.
-
- Cause: Valid non-DIX Ethernet packets as being passed to the
- uIP. uIP will drop these packets but should be logged
- correctly.
-
- Change: These packets are valid, and should only be logged for
- debugging purposes.
-
- 2. Problem: Error message 'Dropped previous transmitted packet' seen.
-
- Cause: The TX ring is full, and here uIP is trying to transmit a
- packet which will be dropped. This is a valid state but
- the log message is marked incorrectly
-
- Change: These messages are not warnings and should be logging when
- debugging is enabled.
-
- 3. Problem: Error message: "iscsi_ipc eth0 Transport name is not
- equal expected: got: bnx2i" seen.
-
- Cause: The iface_rec structure is different between iscsid version.
- For RHEL 5.5, iscsid is versioned 871, for RHEL 6.0 is
- versioned 872.
-
- Change: Allow uIP to compile against a different version of iscsid.
-
-
-uIP v0.5.31 (August 12, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: Softlock would occur showing that the NetLink table
- lock was taken but never released.
-
- Cause: NetLink socket buffer would fill with constant PATH_REQ
- messages preventing PATH_REQ response from libiscsi
-
- Change: Now uIP will drain the NetLink buffer while looking for
- a response.
-
- Enhancements
- ------------
- 1. Change: Add documentation for VLAN configuration and restrictions.
-
-
-uIP v0.5.30 (August 6, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: iscsid thread will stall if closing the uio files nodes
- is stuck
-
- Cause: uIP would indefinitely block waiting for the mutex shared
- by the close routine.
-
- Change: Now uIP will try and poll a bit for the mutex. If it can't
- get this mutex in the iscsid thread then an error is return
- rather then hold the thread.
-
- 2. Problem: IPv6 Unicast Neighbor Adveriserments would have the
- ICMPv6 option header specifying a MAC.
-
- Cause: uIP should use the source IPv6 address to detmine whether
- to strip the option header or not and not the target address
- in the ICMPv6 field.
-
- Change: The uIP stack return a unicast IPv6 Neighbor Advertisement
- without the ICMPv6 option as a response to unicast
- IPv6 Neighbor Solicitations.
-
- 3. Problem: There would be TCP SYN packets with improper MAC address.
-
- Cause: A zero'ed MAC address was not passed to CNIC to indicate an
- error or if the IP address didn't resolve.
-
- Change: The uIP stack will now return a zero'ed MAC address if it
- can't find any entries.
-
-
-uIP v0.5.29 (August 6, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: "uip udp: no matching connection found: lport: 35072"
- seen numerous times in the brcm_iscsiuio log file
-
- Cause: This message was incorrectly marked as an error
-
- Change: These messages are valid log entries especially if the
- packet was a broadcast UDP packet not destined for the SUT
- I will change the code to mark these logs entries as debug.
-
-
-uIP v0.5.28 (August 5, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: Can't login into a redirected Equilogic Target
-
- Cause: The Equilogic Target uses a unicast IPv6 Neighbor
- Solicitation to test if the host is up. The uIP stack
- would return a Neighbor Advertisement with an unneeded
- ICMPv6 option.
-
- Change: Only have the uIP stack return a unicast IPv6 Neighbor
- Advertisement without the ICMPv6 option.
-
- 2. Problem: With older bnx2/bnx2x/cnic/bnx2i driver combinations
- uIP would segfault when these drivers were unloaded.
-
- Cause: When the older drivers were removed, the underlying uio
- instance was removed causing uIP to have a stale file handle.
- When uIP finally closes using this stale file handle, either
- uIP would segfault, or there would be an error in the
- uio_release() path.
-
- Change: Only have the uIP close if the UIO file node exists.
-
-
-uIP v0.5.27 (July 31, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: iSCSI HBA: Unable to use DHCP address for iSCSI interface
- if a connection was previously made with a static address
- on bnx2 devices.
-
- Cause: Because the device is closed and reopen'ed the TX consumer
- indexes were not persisted
-
- Change: Only discard the TX consumer indexes only when the devices
- will be discarded or closed
-
- Enhancements
- ------------
- 1. Change: Change CNIC references to bnx2 in the bnx2 user space
- driver.
-
-
-uIP v0.5.26 (July 30, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: iSCSI HBA: Unable to use DHCP address for iSCSI interface
- if a connection was previously made with a static address on
- bnx2x devices.
-
- Cause: Because the device is closed and reopen'ed the TX consumer
- indexes were not persisted
-
- Change: Only discard the TX consumer indexes only when the devices
- will be discarded
-
- 2. Problem: IPv6 using VLAN's didn't login
-
- Cause: The uIP code used to determine if the packet was an IPv6
- or not was not working. This VLAN packets for IPv6 were
- being mis-interpreted.
-
- Change: Make the function is_ipv6() VLAN aware
-
- 3. Problem: Persistant targets was not loggin in during boot
-
- Cause: If udev was slow and the /dev/uio* were creatly slowly
- uIP would fail.
-
- Change: Poll uIP waiting for /dev/uio* file nodes.
-
-uIP v0.5.25 (July 27, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: When using IPv4 DHCP, there are no initial DHCP Discover
- packets were not seen on the wire.
-
- Cause: Packets generated from the app handler from the uIP stack
- were not placed on the wire.
-
- Change: Packets originating from the uIP stack are now always placed
- on the wire.
-
-uIP v0.5.24 (July 25, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: One would see invalid packet packets flow through the
- uIP stack, where the logs would indicate there is a packet
- with an invalid length
-
- Cause: The BD and CQE consumer indexes were not properly incremented
- and masked.
-
- Change: The BD index is now properly masked. The CQE index is not
- incremented using the CQE index rather the mistaken BD index.
-
- Impact: 10G only
-
- 2. Problem: uIP would segfault during the booting of the machine.
-
- Cause: uIP was using a NULL data pointer because there was an
- incorrect packet passed to the stack.
-
- Change: Only allow uIP to process data if the packet exists.
-
- 3. Problem: uIP would stop processing packets
-
- Cause: The uIP code would not properly drain the CQE ring causing
- it to eventually be full
-
- Change: Consume all the CQE elements even if they are ethernet types
- or not.
-
- Impact: 10G only
-
- 4. Problem: uIP would stop after if/down of the network interface.
-
- Cause: uIP was not kick starting the NIC loop thread properly.
-
- Change: Ensure that the NIC loop thread is started by when iscsid
- request that the interface start the offload. Mark the NIC
- only if the thread is truly canceled.
-
-
-uIP v0.5.23 (July 20, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: Segfault during brcm_iscsiuio initialization
-
- Cause: uIP was using a NULL data pointer, because a different
- thread re-initialized the uIP stack
-
- Change: Properly synchronize the initialization of the stack
-
- 2. Problem: Deadlock during the printing of heavy debug messages
-
- Cause: The variable macro structures would point to invalid
- data
-
- Change: With each invocation of va_copy() a corresponding
- invocation of va_end() in the same function for the proper
- cleanup
-
- 3. Problem: uIP would hang when the interface could go up/down
-
- Cause: uIP would get out of sync with the state of the network
- interface
-
- Change: Instead of detriving state from the UIO file nodes, uIP
- will take direction from iscsid on when interfaces will be
- started.
-
-uIP v0.5.22 (July 15, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: Unable to reconnect via iSCSI offload after
- ifup/ifdown
-
- Cause: uIP was stuck on the thread when closing the NIC main
- loop
-
- Change: Properly synchronize the NetLink CNIC and uevent threads
-
- 2. Problem: uIP would crash during boot up.
-
- Cause: uIP would overwrite a memory location which was already
- freed during nic_remove().
-
- Change: Since the NIC is freed there is no need to write to
- update the NIC flags
-
- Enhancements
- ------------
-
- 1. Change: Added IPv6 Link Local support
-
-
-uIP v0.5.21 (July 5, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: Unable to connect via iSCSI offload after
- changing L2 address
-
- Cause: uIP didn't notice the network inferface going down
-
- Change: Allow uIP to persist the stack's IP address after
- a reset
-
- 2. Problem: Unable to connect via IPv4 and IPv6 concurrently
-
- Cause: uIP didn't notice the network inferface going down
-
- Change: Allow uIP to persist the stack's IP address after
- a reset and properly bring up the interface
-
- 3. Problem: Unable to connect via VLAN
-
- Cause: IP address was no persisted after a device reset
-
- Change: When CNIC requests a path request, uIP will use the
- VLAN passed by the CNIC.
-
-
-uIP v0.5.20 (June 24, 2010)
-
-
-uIP v0.5.20 (June 24, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: Certain IPv6 addresses are not repsonded to by
- the target.
-
- Cause: The MAC was generated from the target's IPv6
- address not the deterived multicast IPv6 address.
-
- Change: The destination MAC address should be deterived
- from the packet's destination IPv6 address and
- not the target.
-
- 2. Problem: brcm_iscsiuio would segfault when L2 interface is
- bought up and down after being logged into
-
- Cause: The NIC thread was not stopped properly
-
- Change: When the UIO device is remove and when the
- cooresponding NIC tracked by brcm_iscsiuio, the
- daemon would properly wait for the NIC thread to
- stop.
-
-
-uIP v0.5.19 (June 22, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: Can't login after boot
-
- Cause: If NIC interfaces are brough up and down quickly
- uIP wait on an invalid NIC thread
-
- Change: Only wait for the NIC thread if the NIC thread
- exists.
-
-uIP v0.5.18 (June 21, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: Does not compile on SLES 11 SP1
-
- Cause: Automake cached files were included as part of the
- uIP-0.5.17 package
-
- Change: Remove automake cached files, and allow these files
- to be generated each time the source is compiled
-
- 2. Problem: Does not always receive multicast packets
-
- Cause: Multicast bit was not set in SORT USER 2 register
-
- Change: brcm_iscsiuio will now set the SORT USER 2 registers
- with both the broadcast and multicast bits.
-
- 3. Problem: Existing iSCSI connections do not reconnect after
- operations which require equivalent driver
- load/unload operations
-
- Cause: Multiple path requests would trample NIC configurations
-
- Change: Allow only one path request at a time
-
-uIP v0.5.17 (June 16, 2010)
-=======================================================
- Fixes
- -----
- 1. Problem: IPv6 neighbor solicitations from brcm_iscsiuio could
- not be responded to
-
- Cause: The IPv6 neighbor solicitation packet had an invalid
- multicast MAC address
-
- Change: Properly set the MAC address multicast bit and OR
- with the IPv6 destination address
-
- 2. Problem: NIC state was not properly synchronized and noticed
- by Shyam Iyer <shiyer@redhat.com>
-
- Change: Properly lock the NIC device when changing state
-
- Enhancements
- ------------
-
- 1. Change: Listen for iscsid before daemonizing to close a timing
- gap which might allow iscsid to start before uIP is
- completely initialized.
-
-uIP v0.5.16 (June 2, 2010)
-=======================================================
-
- Enhancements
- ------------
-
- 1. Change: Formally add IPv6 support. Only a static IPv6 address
- is supported.
-
-uIP v0.5.15 (May 20, 2010)
-=======================================================
-
- Fixes
- -----
- 1. Problem: brcm_iscsiuio would echo packets off the wire
-
- Cause: Stale packets from the uIP stack could potentially
- make it onto the wire causing a network flood
-
- Change: Only place on the wire packets uIP intended to place
- on the wire. Drop all other packets.
-
-uIP v0.5.14 (May 18, 2010)
-=======================================================
-
- Fixes
- -----
- 1. Problem: brcm_iscsiuio would crash when offloading using a
- bnx2x device /dev/mem could not be
- opened, (ie. SE Linux enabled)
-
- Cause: /dev/mem could not be opened, (ie. SE Linux enabled)
- and then the NIC would be improperly initialized.
-
- Change: If /dev/mem is not able to be opened, then the device
- is closed
-
- 2. Problem: brcm_iscsiuio would crash when brcm_iscsiuio is
- being shutdown
-
- Cause: The NIC mutex was deferenced imporperly when the NIC
- is being closed
-
- Change: Take the NIC mutex lock only when the NIC is closed.
-
-uIP v0.5.13 (May 16, 2010)
-=======================================================
-
- Fixes
- -----
- 1. Problem: brcm_iscsiuio would crash with heavy traffic directed
- at the iSCSI traffic
-
- Cause: Packets which are sized between 1006-1024 bytes would
- crash brcm_iscsiuio because brcm_iscsiuio is not sized
- to handle such large packets
-
- Change: Drop large packets, properly hold the NIC mutex lock
- for the duration when NIC fields are being used.
-
-
-uIP v0.5.12 (May 13, 2010)
-=======================================================
-
- Fixes
- -----
- 1. Problem: brcm_iscsiuio could crash on when L2 interface is
- ifdown'ed
-
- Cause: The local NIC pointer was not initialized properly
- in the routine parse_iface()
-
- Change: Properly initialize the NIC pointer
-
- 2. Problem: Documentation referred to older admin_client which
- doesn't exist any more because brcm_iscsiuio uses
- the iscsid iface file
-
- Change: Remove the stale references
-
-
-uIP v0.5.11 (May 11, 2010)
-=======================================================
-
- Fixes
- -----
- 1. Problem: brcm_iscsiuio could crash on invalid packet sizes
-
- Cause: The hardware BD could be a large value because of a
- hardware error
-
- Change: Limit the size of the packet dumped to the MTU size
-
- Enhancements
- ------------
-
- 1. Change: During the running of the configure script now
- the script will check for ar and ranlib binaries
-
-
-uIP v0.5.10 (May 03, 2010)
-=======================================================
-
- Fixes
- -----
- 1. Problem: BCM57712 not recognized
-
- Cause: The PCI ID's in the bnx2x file were missing.
-
- Change: Added proper BCM57712, BCM57712E, BCM57713, BCM57713E
- PCI ID's
-
- 2. Problem: (CQ 47481) brcm_iscsiuio not installed in correct location
-
- Cause: Default install path for autoconf is /usr/local
-
- Change: Change the default prefix to '/' so the brcm_iscsiuio
- binary is installed to /sbin/
-
- Enhancements
- ------------
-
- 1. Change: Remove dependency on Yacc and Lex
-
-
-uIP v0.5.9 (April 28, 2010)
-=======================================================
-
- Fixes
- -----
- 1. Problem: bnx2x T6.0 driver would not login
-
- Cause: The bnx2x code was not using the T6.0 HSI offsets
-
- Change: Determine to bnx2x driver version eariler to properly use the
- T4.8 or T6.0 HSI
-
- Enhancements
- ------------
-
- 1. Change: Collapse all the various locks to use the NIC lock to shrink
- memory footprint
-
- 2. Change: Consolidate upper layer checksumming code
-
-

- iface before logging in
-
-uIP v0.5.6 (Mar 05, 2009)
-=======================================================
- Fixes
- -----
- 1. Problem: bnx2x panic dump would be seen when sending
- traffic to uIP
-
- Cause: The TX producer index was not properly
- incrementing when the wrapping occured
-
- Change: Do not skip the last TX producer index like the
- TX BD's
-
- Impact: None.

- NIC thread is destroyed when the host network
- interface is brought down.
-
- Impact: None.
-
-
-uIP v0.5.1 (Dec 9, 2009)
-=======================================================
- Fixes
- -----

-* A new API: protosockets that are similar to BSD sockets but does not
- require any underlying multithreading system.
-
-* Very rudimentary IPv6 support
-
-* New application: DHCP client. Web server rewritten with protosockets.
-
-* Removed uIP zero-copy functionality in order to simplify uIP device
- driver coding: outbound packets are now *always* stored in full in
- the uip_buf buffer.
-
-* Checksum computation is now part of uip.c, but it still is possible
- to implement them in assembly code by specifying a configuration
- option. Checksum code now runs on architectures with 2-byte alignment.
-
-* Added TCP persistent timer.
-
-* Made all IP address representations use the new uip_ipaddr_ip
- datatype for clarity.
-
-* Updated window behavior so that sending to a host with a small open
- window works better now.
-
-* UDP API change: uip_udp_new() now takes port numbers in network byte
- order like TCP functions.
-
-* Allow reception of packets when no IP address is configured to make
- DHCP work.
-
-* Moved Ethernet address into main uIP module from ARP module.
-
-* Made constants explicit #defines and moved them out of the code
- (header sizes, TCP options, TCP header length field).
-
-* If uip_len is less than that reported by the IP header, the packet
- is discarded. If uip_len is greater than the length reported by the
- IP header, uip_len is adjusted.
-
-* Moved header size definitions into header file.
-
-* Added uIP call for polling an application without triggering any
- timer events. Removed redundant assignments of uip_len and uip_slen.
-
-* Removed compiler warning about icmp_input label being defined when
- UIP_PINGADDRCONF was not used.
-
-* Added UIP_APPDATA_SIZE macro that holds the available buffer size
- for user data.
-
-* Added uip_udp_bind() call.
-
-* Moved checksum code into main uIP module.
-
-* Switched the TCP, UDP and IP header structures to be structs rather
- than typedefs.
-
-* Prefixed TCP state names with UIP_ to avoid name space
- contamination.
-
-* Changed declarations of uip_appdatap and friends to void * to avoid
- explicit typecasts.
-
-* Bugfixes
-
- o TCP: Fixed bug with high byte of peer window size.
-
- o TCP: Fixed bug that in some cases prevented concurrent reception and
- transmission of TCP data.
-
- o TCP: uip_connect() didn't correctly calculate age of TIME_WAIT
- connections.
-
- o TCP: Array index for uip_conns[] array was out of bounds in
- comparison. Comparison changed to make index within bounds.
-
- o TCP: if the remote host crashes and tries to reestablish an old
- connection, uIP should respond with an ACK with the correct
- sequence and acknowledgment numbers, to which the remote host
- should respond with an ACK. uIP did not respond with the correct
- ACK.
-
- o TCP: Fixed check for SYNACK segment: now checks only relevant TCP
- control flags and discards flags reserved for future expansion.
-
- o TCP: Fixed bug where uIP did not inform application that a connection
- had been aborted during an active open.
-
- o TCP: FIN segment was accepted even though application had stopped
- incoming data with uip_stop().
-
- o TCP: A FINACK segment would not always correctly acknowledge data.
-
- o UDP: checksums are now calculated after all fields have been
- filled in.
-
- o UDP: network byte order on lastport in uip_udp_new().
-
- o IP: memset() bugs in IP fragment reassembly code fixed.

-/**
- * \defgroup psock Protosockets library
- * @{
- *
- * The protosocket library provides an interface to the uIP stack that is
- * similar to the traditional BSD socket interface. Unlike programs
- * written for the ordinary uIP event-driven interface, programs
- * written with the protosocket library are executed in a sequential
- * fashion and does not have to be implemented as explicit state
- * machines.
- *
- * Protosockets only work with TCP connections.
- *
- * The protosocket library uses \ref pt protothreads to provide
- * sequential control flow. This makes the protosockets lightweight in
- * terms of memory, but also means that protosockets inherits the
- * functional limitations of protothreads. Each protosocket lives only
- * within a single function. Automatic variables (stack variables) are
- * not retained across a protosocket library function call.
- *
- * \note Because the protosocket library uses protothreads, local
- * variables will not always be saved across a call to a protosocket
- * library function. It is therefore advised that local variables are
- * used with extreme care.
- *
- * The protosocket library provides functions for sending data without
- * having to deal with retransmissions and acknowledgements, as well
- * as functions for reading data without having to deal with data
- * being split across more than one TCP segment.
- *
- * Because each protosocket runs as a protothread, the protosocket has to be
- * started with a call to PSOCK_BEGIN() at the start of the function
- * in which the protosocket is used. Similarly, the protosocket protothread can
- * be terminated by a call to PSOCK_EXIT().

- * uIP is a small implementation of the IP, UDP and TCP protocols (as
- * well as some basic ICMP stuff). The implementation couples the IP,
- * UDP, TCP and the application layers very tightly. To keep the size
- * of the compiled code down, this code frequently uses the goto
- * statement. While it would be possible to break the uip_process()
- * function into many smaller functions, this would increase the code
- * size because of the overhead of parameter passing and the fact that
- * the optimier would not be as efficient.
- *
- * The principle is that we have a small buffer, called the uip_buf,
- * in which the device driver puts an incoming packet. The TCP/IP
- * stack parses the headers in the packet, and calls the
- * application. If the remote host has sent data to the application,
- * this data is present in the uip_buf and the application read the
- * data from there. It is up to the application to put this data into
- * a byte stream if needed. The application will not be fed with data
- * that is out of sequence.
- *
- * If the application whishes to send data to the peer, it should put
- * its data into the uip_buf. The uip_appdata pointer points to the
- * first available byte. The TCP/IP stack will calculate the
- * checksums, and fill in the necessary header fields and finally send
- * the packet back to the peer.

- * This file handles different qedi NIC operations,
- * qedi_open - initializes all hardware resources under NIC device
- * qedi_close - closes the NIC device
- * qedi_read - reads data to the hardware
- * qedi_write - writes data to the hardware
- * qedi_start_xmit - sends a pkt of data on NIC device
- * qedi_get_tx_pkt - gets a Tx pkt from NIC
- * qedi_clear_tx_intr - clears the Tx interrupt
- * NOTE: nic_t is used as NIC device,
- * qedi is not attached to netdev hence it is not mandatory
- * for netdev to be upd
