Description Kirill Pisman 2004-07-07 17:52:51 UTC

Description of problem:

We had utility that uses quotactl syscall. It's broken after upgrade
from kernel-2.4.22-1.2115.nptl to kernel-2.4.22-1.2197.nptl.

Syscall is stalled during operation. strace output fragment:

quotactl(0xff800003 /* Q_??? */|USRQUOTA, "/dev/sda1", 0, NULL) = -1
ESRCH (No s
uch process)
quotactl(0xff800002 /* Q_??? */|USRQUOTA, "/dev/sda1", 2,

after this utility is stalled.

How reproducible:

quotaon qutaoff in loop.

  
Actual results:

 Sometime after quotaon or qutaoff  will stall silently.
quotacheck will not run in this time, so quouta subsystem are fulyy
stalled.
 Additionaly when i try to reboot machine reboot script is stops with
message about quotactl process not found, or someting like this during
turning quotas off, so without a physical access to machine it's
impossible to make it alive again.
 
Expected results:

Infinit loop of enabling and disabling quota.

Additional info:

I dont know affected other kernel versions(patches ) or not, maybe
this bug is apper in earlier kernel updates to.

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/

Comment 2 Kirill Pisman 2004-09-30 08:12:02 UTC

 I am personaly knows about existance of Fedora Leagcy, but many
customers a not satisfied with usage of Fedora Legacy instead of
fedora's own repository. RHEL are not suitaable for those customers as
to expencive systems for this moment. You a loosing popularity with so
frequent and full end of life's of your products.
 But anyway i am cannot do anythig here, and i know Fedora 1 is not
supported anymore.

 Bug is seems to be less agressive in 2.4.22-1.2199.nptl.
