2015-12-22resolv: fix gethostbyname2_r to match gethostbyname_r, fixing bugs with AAAA ↵Waldemar Brodkorb
lookups The latter half of gethostbyname2_r (doing AAAA queries) is rather dramatically different from the corresponding portion of gethostbyname_r (doing A queries). This leads to problems like calls to getaddrinfo only returning one IPv6 address, even when multiple exist. Seems to be entirely a case of divergent evolution -- a half-decade of fixes for the IPv4 code but no love for IPv6. Until now. ;) DNS behaviour for IPv6 is really no different than for IPv4 -- beyond the difference in address sizes, there's no need for the functions to be so different. Consequently, this patch really is almost just a cut-and-paste of gethostbyname_r, with the appropriate substitutions of in6_addr, AF_INET6, etc; while holding on to the few extra bits that actually belong in there (eg #ifdef __UCLIBC_HAS_IPV6__).

This reverts commit 4a05ed87ceb946608100642121c32e642b58cd0d. This breaks SSP detection for gcc, which might be problematic for some projects. Revert it after some discussion with buildroot and openembedded people.

2015-12-17Fix syslog messages lost if syslogd is temporary busyVladislav Grishenko
Commit 4139fe5aec935ba3f462dcaf6aafb6e5eadf1ab9 fixes SIGSTOPed syslogd issue. but introduced new one - messages will be lost when socket buffer gets full, not only if syslogd is stalled, but even if it accepts message slower than someone sends and possibly leads to security hole, when important messages get lost as result of attacker flooding. Patch adds 1 second waiting for socket buffer can accept the message, helps when syslogd is working hard. If it's stalled/SIGSTOPed, message will be sent to errout as before. After that, further non-blocking /dev/log connect attempts will fail immediately with EAGAIN error until syslogd reads some from it. function old new delta openlog_intern 259 355 +96 static.tv - 8 +8 .rodata 151 159 +8 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 2/0 up/down: 112/0) Total: 112 bytes Signed-off-by: Vladislav Grishenko <themiron@mail.ru>
