The following bug has been logged online: Bug reference: 5121 Logged by: Ryan Douglas Email address: rdoug...@arbinet.com PostgreSQL version: 8.4.1 Operating system: Fedora 11 Description: Segmentation Fault when using pam w/ krb5 Details:
Whenever I use psql to remotely connect to the database the server crashes (see log below). If I use psql with the '-W' option then it's fine. I also tested with pam_tacplus.so and in both cases the db didn't crash. It just complained about not having credentials to authenticate when the -W option is not used. I can reproduce at will so let me know if you need more information. ----- pam configuration auth sufficient pam_krb5.so no_user_check account required pam_permit.so session required pam_permit.so -------- postgresql log -with krb5 configured in pam ------ <[unkno...@[unknown] 2009-10-15 16:21:11.939 EDT>LOG: connection received: host=10.0.20.38 port=42662 <rdoug...@tacacs 10.0.20.38(42662) 2009-10-15 16:21:11.982 EDT>LOG: could not receive data from client: Connection reset by peer <@ 2009-10-15 16:21:11.987 EDT>LOG: server process (PID 16978) was terminated by signal 11: Segmentation fault <@ 2009-10-15 16:21:11.987 EDT>LOG: terminating any other active server processes <@ 2009-10-15 16:21:11.989 EDT>LOG: all server processes terminated; reinitializing <@ 2009-10-15 16:21:12.109 EDT>LOG: database system was interrupted; last known up at 2009-10-15 16:21:07 EDT <@ 2009-10-15 16:21:12.109 EDT>LOG: database system was not properly shut down; automatic recovery in progress <@ 2009-10-15 16:21:12.110 EDT>LOG: record with zero length at 3/B7C396B8 <@ 2009-10-15 16:21:12.110 EDT>LOG: redo is not required <@ 2009-10-15 16:21:12.137 EDT>LOG: database system is ready to accept connections <@ 2009-10-15 16:21:12.137 EDT>LOG: autovacuum launcher started -------- postgresql log -with tacplus configured in pam ------ <[unkno...@[unknown] 2009-10-15 16:41:01.544 EDT>LOG: connection received: host=10.0.20.38 port=58894 <rdoug...@tacacs 10.0.20.38(58894) 2009-10-15 16:41:01.575 EDT>LOG: could not receive data from client: Connection reset by peer <rdoug...@tacacs 10.0.20.38(58894) 2009-10-15 16:41:01.576 EDT>LOG: pam_authenticate failed: Insufficient credentials to access authentication data <rdoug...@tacacs 10.0.20.38(58894) 2009-10-15 16:41:01.576 EDT>FATAL: PAM authentication failed for user "rdouglas" <[unkno...@[unknown] 2009-10-15 16:41:05.298 EDT>LOG: connection received: host=10.0.20.38 port=58895 <rdoug...@tacacs 10.0.20.38(58895) 2009-10-15 16:41:05.681 EDT>LOG: connection authorized: user=rdouglas database=tacacs ---- /var/log/messages ---- Oct 15 16:21:07 va-mp-db02 kernel: postgres[16971]: segfault at 0 ip 0000000000559624 sp 00007fff43dbe180 error 4 in postgres[400000+439000] Oct 15 16:21:11 va-mp-db02 kernel: postgres[16978]: segfault at 0 ip 0000000000559624 sp 00007fff43dbe180 error 4 in postgres[400000+439000] - -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
