Subject: [PATCH] net/dump.c: Suppress spurious compiler warning
|

MIME-Version: 1.0

Compiling with gcc version 11.2.0 (Ubuntu 11.2.0-13ubuntu1) results in
|
||
a (spurious) warning:
|
||
|
||
In function ‘dump_receive_iov’,
|
||
inlined from ‘filter_dump_receive_iov’ at ../net/dump.c:157:5:
|
||
../net/dump.c:89:9: error: ‘writev’ specified size 18446744073709551600
|
||
exceeds maximum object size 9223372036854775807 [-Werror=stringop-overflow=]
|
||
89 | if (writev(s->fd, dumpiov, cnt + 1) != sizeof(hdr) + caplen) {
|
||
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
In file included from /home/ptomsich/qemu/include/qemu/osdep.h:108,
|
||
from ../net/dump.c:25:
|
||
../net/dump.c: In function ‘filter_dump_receive_iov’:
|
||
/usr/include/x86_64-linux-gnu/sys/uio.h:52:16: note: in a call to function
|
||
‘writev’ declared with attribute ‘read_only (2, 3)’
|
||
52 | extern ssize_t writev (int __fd, const struct iovec *__iovec, int
|
||
__count)
|
||
| ^~~~~~
|
||
cc1: all warnings being treated as errors
|
||
|
||
This change helps that version of GCC to understand what is going on
|
||
and suppresses this warning.
