Fixes a segfault in nscd when using nss-myhostname. Nscd expects that an NSS module's gethostbyname4_r function returns its first result in the pre-allocated gaih_addrtuple denoted by **pat. (See nscd/aicache.c in the Glibc sources.) However, nss-myhostname doesn't fill in **pat but allocates the first result in ‘buffer’, then sets *pat. So nscd crashes (e.g. when running ‘getent ahosts my-machine’). Hard to tell if this is a bug in nscd, since there doesn't seem to be a proper API spec for gethostbyname4_r. But in any case, this patch fixes the crash by copying the first result to **pat. |
