Stefan Liebler 4b2e40a925 Handle out-of-memory case in svc_tcp.c/svc_unix.c:rendezvous_request. ... If glibc is build with -O3 on at least 390 (-m31) or x86 (-m32), gcc 11 dumps this warning: svc_tcp.c: In function 'rendezvous_request': svc_tcp.c:274:3: error: 'memcpy' offset [0, 15] is out of the bounds [0, 0] [-Werror=array-bounds] 274 | memcpy (&xprt->xp_raddr, &addr, sizeof (addr)); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors In out-of-memory case, if one of the mallocs in makefd_xprt function returns NULL, a message is dumped, makefd_xprt returns NULL and the subsequent memcpy would copy to NULL. Instead of a segfaulting, we delay a bit (see also __svc_accept_failed and Bug 14889 (CVE-2011-4609) - svc_run() produces high cpu usage when accept() fails with EMFILE (CVE-2011-4609). The same applies to svc_unix.c. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>		2020-12-10 11:11:20 +01:00
