--- Comment #13 from Ryan Tandy <[email protected]> --- I may have set up my environment incorrectly for this, but I don't see how the patch fixes the issue described, since getaddrinfo() is also backed by NSS. With the patch applied (note getaddrinfo() at #7) I still see nss_ldap deadlocking with itself: (gdb) bt #0 0x00007ffff7d1329c in __lll_lock_wait () from /lib/x86_64-linux-gnu/libpthread.so.0 #1 0x00007ffff7d0c714 in pthread_mutex_lock () from /lib/x86_64-linux-gnu/libpthread.so.0 #2 0x00007ffff7dd8683 in _nss_ldap_enter () at ldap-nss.c:595 #3 0x00007ffff7dd9fbc in _nss_ldap_getbyname (args=args@entry=0x7fffffffc500, result=0x7fffffffc650, buffer=0x7fffffffc8c0 "\377\002", buflen=1024, errnop=0x7ffff7fcb4c0, filterprot=0x7ffff7dee980 <_nss_ldap_filt_gethostbyname> "(&(objectClass=ipHost)(cn=%s))", sel=LM_HOSTS, parser=0x7ffff7ddc5e0 <_nss_ldap_parse_hostv4>) at ldap-nss.c:3509 #4 0x00007ffff7ddc645 in _nss_ldap_gethostbyname2_r (af=<optimized out>, h_errnop=0x7ffff7fcb524, errnop=<optimized out>, buflen=<optimized out>, buffer=<optimized out>, result=<optimized out>, name=<optimized out>) at ldap-hosts.c:287 #5 _nss_ldap_gethostbyname2_r (name=<optimized out>, af=<optimized out>, result=<optimized out>, buffer=<optimized out>, buflen=<optimized out>, errnop=<optimized out>, h_errnop=0x7ffff7fcb524) at ldap-hosts.c:269 #6 0x00007ffff7eebfb7 in ??
