From 723adb650a31859d7cc45832cb8adca0206455ed Mon Sep 17 00:00:00 2001
From: Sandra Loosemore <sandra@codesourcery.com>
Date: Thu, 25 Apr 2019 07:27:02 -0700
Subject: [PATCH] Detect invalid length field in debug frame FDE header.
GDB was failing to catch cases where a corrupt ELF or core file
contained an invalid length value in a Dwarf debug frame FDE header.
It was checking for buffer overflow but not cases where the length was
negative or caused pointer wrap-around.
In addition to the additional validity check, this patch cleans up the
multiple signed/unsigned conversions on the length field so that an
unsigned representation is used consistently throughout.
This patch fixes CVE-2017-9778 and PR gdb/21600.
2019-04-25 Sandra Loosemore <sandra@codesourcery.com>
Kang Li <kanglictf@gmail.com>
PR gdb/21600
* dwarf2-frame.c (read_initial_length): Be consistent about using
unsigned representation of length.
(decode_frame_entry_1): Likewise. Check for wraparound of
end pointer as well as buffer overflow.

Use get_remote_packet_size in download_tracepoint
This patch changes the remote target to use the remote packet size to
build QTDP packets, and to check if there is enough room for the
packet.
I changed the function to raise an error if the packet is too small,
instead of aborting gdb (through xsnprintf). It isn't clear if gdb
will be in a consistent state with respect to the stub after this,
since it's possible that some packets will be sent but not others, and
there could be an incomplete tracepoint on the stub.
The char array used to build the packets is changed to a
gdb::char_vector and sized with the result from
get_remote_packet_size.
When checking if the buffer is large enough to hold the tracepoint
condition agent expression, the length of the expression is multiplied
by two, since it is encoded with two hex digits per expression
byte. For simplicity, I assume that the result won't overflow, which
can happen for very long condition expressions.
gdb/ChangeLog:
2018-08-06 Pedro Franco de Carvalho <pedromfc@linux.ibm.com>
* remote.c (remote_target::download_tracepoint): Remove BUF_SIZE.
Replace array buf with gdb::char_vector buf, of size
get_remote_packet_size (). Replace references to buf and
BUF_SIZE to buf.data () and buf.size (). Replace strcpy, strcat
and xsnprintf with snprintf. Raise errors if the buffer is too
small.

commit 4277c4b87addb5354cc47b98d7a73e44cfaf22c2
Author: Pedro Franco de Carvalho <pedromfc@linux.ibm.com>
Date: Mon Aug 6 16:24:55 2018 -0300
Use remote register numbers in tracepoint mask
Currently, tracepoint register masks in the QTDP packets include both
internal and remote register numbers, as well as pseudo-register
numbers.
This patch changes this so that the mask only includes remote register
numbers.
Register numbers from agent expressions are already set in the mask
using remote numbers. Other tracepoint actions used internal numbers,
e.g. "collect $regs" or "collect $<pseudoreg>". To handle pseudoreg
numbers, an empty agent expression is created and ax_reg_mask is
called for this expression and the pseudoreg. This will cause the ax
to set its mask with the corresponding remote raw register
numbers (using ax_regs_mask, which calls
gdbarch_ax_pseudo_register_collect).
If ax_regs_mask and gdbarch_ax_pseudo_register_collect also generate
more ax bytecode, the ax is also appended to the collection list. It
isn't clear that this was the original intent for
gdbarch_ax_pseudo_register_collect, and none of the arches seem to do
this, but if this changes in the future, it should work.
The patch also refactors the code used by validate_action line to
validate axs into a function that is now called from every place that
generates axs. Previously, some parts of tracepoint.c that generated
axs didn't check if the ax length was greater than MAX_AGENT_EXPR_LEN.

Variable size for regs mask in collection list
This patch changes collection_list to allow larger register masks.
The mask is changed from an array to a vector and is initialized to
hold the maximum possible remote register number. The stringify
method is updated to resize temp_buf if needed.
gdb/ChangeLog:
2018-08-06 Pedro Franco de Carvalho <pedromfc@linux.ibm.com>
* tracepoint.h (collection_list) <m_regs_mask>: Change type to
std::vector<unsigned char>.

m_regs_mask initializer from initializer list. Resize
m_regs_mask using the largest remote register number.
(collection_list::add_remote_register): Remove size check on
m_regs_mask. Use at to access element.
(collection_list::stringify): Change type of temp_buf to
gdb::char_vector. Update uses of temp_buf. Resize if needed to
stringify the register mask. Use pack_hex_byte for the register
mask.

Allow larger regblock sizes when saving tracefiles
The tracefile.c:trace_save function assumes trace_regblock_size won't
be larger than the MAX_TRACE_UPLOAD constant, used to size the buffer
which holds trace data. This can cause buffer overruns when this is
not the case. This patch changes this function so that the larger
size is used to size the buffer.
