Handle out-of-memory case in svc_tcp.c/svc_unix.c:rendezvous_request.

2020-12-10T10:11:20Z

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

These functions should eventually have the same type, so it makes sense to declare them together. Tested-by: Carlos O'Donell Reviewed-by: Carlos O'Donell

Move from sunrpc to inet

2020-07-17T13:19:35Z

Restore as an installed header. Delete the dummy header resolv/rpc/netdb.h because inet is not an optional glibc component (so its is always available). Fixes commit acb527929d0c2b3bb0798472c42ddb3203729708 ("Move non-deprecated RPC-related functions from sunrpc to inet") in combination with commit 5500cdba4018ddbda7909bc7f4f9718610b43cf0 ("Remove --enable-obsolete-rpc configure flag").

Remove --enable-obsolete-nsl configure flag

2020-07-08T15:25:57Z

this means that *always* libnsl is only built as shared library for backward compatibility and the NSS modules libnss_nis and libnss_nisplus are not built at all, libnsl's headers aren't installed. This compatibility is kept only for architectures and ABIs that have been added in or before version 2.28. Replacement implementations based on TIRPC, which additionally support IPv6, are available from . This change does not affect libnss_compat which does not depended on libnsl since 2.27 and thus can be used without NIS. libnsl code depends on Sun RPC, e.g. on --enable-obsolete-rpc (installed libnsl headers use installed Sun RPC headers), which will be removed in the following commit.

sunrpc: Remove hidden aliases for global data symbols (bug 26210)

2020-07-08T06:39:39Z

It is generally not possible to add hidden aliases for global data symbols: If the main executable contains a copy relocation against the symbol, the hidden aliases keep pointing to the glibc-internal copy of the symbol, instead of the symbol actually used by the application.
