[Bug 236216] New: unhelpful error if /proc is mounted read-only
https://bugzilla.novell.com/show_bug.cgi?id=236216 Summary: unhelpful error if /proc is mounted read-only Product: openSUSE 10.2 Version: RC 5 Platform: Other OS/Version: Other Status: NEW Severity: Minor Priority: P5 - None Component: Basesystem AssignedTo: mc@novell.com ReportedBy: mls@novell.com QAContact: qa@suse.de CC: kukuk@novell.com Somehow /proc got remounted ro on my system. This resulted that all ssh login attempts failed without displaying any error message and a console login just printed "Cannot make/remove an entry for the specified session". Not helpful at all. Even root can no longer log in. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

D.o.S, not even the root can login 3. only solution for the problem is restart the computer. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=236216 ------- Comment #2 from mls@novell.com 2007-01-19 04:22 MST ------- A likely cause is the build script from build.rpm. It contained 'mount -oro -n -tproc none $BUILD_ROOT/proc'. This was no issue with old kernel versions, where the proc mounts were not shared. With the current kernel, a read-only re-mount will also change the mount options of /proc... You should change the -oro to -orw... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

A likely cause is the build script from build.rpm. It contained 'mount -oro -n -tproc none $BUILD_ROOT/proc'.
It **still contains** ;) hopefully somebody comes with an update for that... This was no issue with
old kernel versions, where the proc mounts were not shared. With the current kernel, a read-only re-mount will also change the mount options of /proc...
You should change the -oro to -orw...
Thank you mls . that might do the trick ;) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

The application cannot print another error message, but the real problem is logged to syslog(). So everything is ok/cannot be changed. required is what all distributions are using and was in the initial spec for the audit stuff. Only the security/audit experts can answer this. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

It should at least contain the errno message ("read only filesystem"). Please fix your package. And I don't see why the application can't use pam_strerror and print an error message. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
