The above occurs when using the "strict" policy. Using "targeted" it is likely to work without problems although I have not yet tested this. In any case using "targeted" will give different symptoms if it fails. Looks like the openssh-selinux.patch wasn't properly updated for openssh-3.9p1, and unfortunately it happened to compile nonetheless. In sshpty.c, the -selinux patch is referencing "ttyname" whereas the function parameter is now named "tty". It happens to compile (albeit with warnings) because ttyname is defined in global scope for ttyname(3), so I guess we are passing a _function pointer_ here rather than the tty name. s/ttyname/tty/g please in the openssh-selinux.patch. This should be fixed in 3.9p1-2 and later. Please reopen if you find that this is not the case. Thanks! |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (compatible; Konqueror/3.3; Linux) (KHTML, like Gecko) Description of problem: After upgrading my server to openssh-server-3.9p1-1 I could not login any more. The sshd was not relabelling the terminal device node to the new SE Linux context, so the context remained as sshd_devpts_t instead of being correctly set to user_devpts_t or staff_devpts_t. The previous version worked well. I can give you administrative access to a SE Linux test machine running the latest rawhide to duplicate this if necessary. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: Upgrade a SE Linux machine to the latest rawhide and observe that you can't login. Actual Results: The below message appears in /var/log/messages and the session is terminated. avc: denied { read write } for pid=18055 exe=/bin/bash path=/dev/pts/1 dev=devpts ino=3 scontext=root:staff_r:staff_t tcontext=root:object_r:sshd_devpts_t tclass=chr_file Additional info:
