commit f8020794aea5d4feb38683fc8301ee04a4fc4759
Author: Florian Weimer <fweimer>
Date: Wed May 4 14:45:17 2016 +0200
getnameinfo: Return EAI_OVERFLOW in more cases [BZ #19787]
The AF_LOCAL and AF_INET/AF_INET6 non-numerci service conversion
did not return EAI_OVERFLOW if the supplied buffer was too small,
silently returning truncated data. In the AF_INET/AF_INET6
numeric cases, the snprintf return value checking was incorrect.
(cherry picked from commit 066746783d6c6c0f61b39c741177e24a9b398a20)
commit 05d2606fa110a8afd85419d969a6d55bf88efb0f
Author: Florian Weimer <fweimer>
Date: Wed May 4 14:35:23 2016 +0200
getnameinfo: Avoid calling strnlen on uninitialized buffer
In the numeric AF_INET/AF_INET6 case, if inet_ntop fails
as the result of a short host buffer, we used to call strnlen
on the uninitialized host buffer.
(cherry picked from commit 1c3490d4b29fc5b3f30dd6b13082046aee94443d)
commit c5aae1035cac6305a111e3461af23a924914d9f5
Author: Florian Weimer <fweimer>
Date: Wed May 4 14:35:12 2016 +0200
getnameinfo: Reduce line length and add missing comments
(cherry picked from commit c9b0e6a432e827b61f12eb52c2aaeadc77b64461)
commit e5bcbfc23b356b62ebfcd1943655eab45a9ca87c
Author: Florian Weimer <fweimer>
Date: Fri Apr 29 17:08:06 2016 +0200
getnameinfo: Refactor and fix memory leak [BZ #19642]
Split getnameinfo into separate functions for host and service
lookups, and for different address families.
(cherry picked from commit 2dce81a319601e1ee110f7316f705b48c5686e72)
commit 42a496388d00a6eb781e0b1c6754ae1f38790531
Author: Florian Weimer <fweimer>
Date: Thu Apr 28 17:41:49 2016 +0200
getnameinfo: Do not preserve errno
POSIX does not require it, the companion getaddrinfo implementation
does not do it, and this behavior is not documented in the manual
page, either.
(cherry picked from commit 2b54cbce2c363ab6ae89d10657d7465858116d7a)
