* [Bug nscd/11928] New: nscd does not account for 'multi on' in /etc/host.conf when ai-resolving hosts @ 2010-08-19 20:15 pasky at suse dot cz 2010-08-19 20:23 ` [Bug nscd/11928] " pasky at suse dot cz 2010-08-22 14:42 ` pasky at suse dot cz 0 siblings, 2 replies; 3+ messages in thread From: pasky at suse dot cz @ 2010-08-19 20:15 UTC (permalink / raw) To: glibc-bugs When nscd is handling getaddrinfo() resolution requests, it fails to properly initialize its resolver options state and ignores /etc/host.conf. An easy way to reproduce this is by putting 'multi on' in /etc/host.conf and cat >>/etc/host.conf <<EOT 1.2.3.4 test 1.2.3.5 test EOT Then, with nscd stopped: $ getent ahosts test 1.2.3.4 STREAM test 1.2.3.4 DGRAM 1.2.3.4 RAW 1.2.3.5 STREAM 1.2.3.5 DGRAM 1.2.3.5 RAW However, with nscd running: $ getent ahosts test 1.2.3.4 STREAM test 1.2.3.4 DGRAM 1.2.3.4 RAW -- Summary: nscd does not account for 'multi on' in /etc/host.conf when ai-resolving hosts Product: glibc Version: 2.12 Status: NEW Severity: normal Priority: P2 Component: nscd AssignedTo: drepper at redhat dot com ReportedBy: pasky at suse dot cz CC: glibc-bugs at sources dot redhat dot com http://sourceware.org/bugzilla/show_bug.cgi?id=11928 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ^ permalink raw reply [flat|nested] 3+ messages in thread

However, this would not be enough since nscd has its own _res_hconf due to nscd/res_hconf.c; _res_hconf_init() would work on different _res_hconf instance than the NSS routines. We just need to make sure nscd and glibc share the same _res_hconf instance - this should not be a problem since users should run matching versions of glibc and nscd anyway. -- http://sourceware.org/bugzilla/show_bug.cgi?id=11928 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ^ permalink raw reply [flat|nested] 3+ messages in thread
