Me too. Message on server console when trying to ssh from clinet. sshd[1409]: segfault at ffffffff830b7830 ip 00007f9881a8dc58 sp 00007fffd3faddd0 error 4 in libaudit.so.1.0.0[7f9881a87000+16000] Problem goes away with downgrade to: openssh-5.6p1-8.fc15.x86_64.rpm Doesn't seem to happen on i686. *** This bug has been marked as a duplicate of bug 639048 *** |
Created attachment 450772 [details] strace of the segfaulting process Description of problem: sshd crashes before asking for password. Looks to be working with -8/-7 or older. Version-Release number of selected component (if applicable): openssh-5.6p1-9.fc15.x86_64 audit-libs-2.0.4-4.fc14.x86_64 How reproducible: always Steps to Reproduce: 1. ssh localhost 2. accept unknown key warning Actual results: no password prompt, sshd[4441]: segfault at 58258880 ip 00007feb565a8c58 sp 00007fff81415520 error 4 in libaudit.so.1.0.0[7feb565a2000+16000] Additional info: I was unable to grab a backtrace, attaching to sshd and setting "set follow-fork-mode child" won't stop on segfault and I only get "Program exited with code 0377." No abrt here (various reasons), debugging hints welcome, already reported the gdb issue to jkratochvil. So attaching a strace report instead.
