Subject: [PATCH] multipath-tools tests: fix stringop-overflow build errors
|
||
|
|
with gcc 11
|
||
|
|
|
||
|
|
gcc-11 throws an error compiling alias.c and dmevents.c:
|
||
|
|
|
||
|
|
In file included from ../libmultipath/checkers.h:4,
|
||
|
|
from ../libmultipath/prio.h:7,
|
||
|
|
from ../libmultipath/structs.h:8,
|
||
|
|
from dmevents.c:29:
|
||
|
|
../multipathd/dmevents.c: In function 'dmevent_loop':
|
||
|
|
../multipathd/dmevents.c:357:17: error: '__sigsetjmp' accessing 200 bytes in a region of size 72 [-Werror=stringop-overflow=]
|
||
|
|
357 | pthread_cleanup_push(cleanup_lock, &waiter->vecs->lock);
|
||
|
|
| ^~~~~~~~~~~~~~~~~~~~
|
||
|
|
../multipathd/dmevents.c:357:17: note: referencing argument 1 of type 'struct __jmp_buf_tag *'
|
||
|
|
/usr/include/pthread.h:734:12: note: in a call to function '__sigsetjmp'
|
||
|
|
734 | extern int __sigsetjmp (struct __jmp_buf_tag *__env, int __savemask) __THROWNL;
|
||
|
|
| ^~~~~~~~~~~
|
||
|
|
|
||
|
|
The reason seems to be a mismatch between the __sigsetjmp() prototype
|
||
|
|
in <setjmp.h> and <pthread.h>. The error is encountered iUntil this is fixed in the toolchain,
|
||
|
|
work around it by including <pthread.h> before <setjmp.h>.
