2.6.33-rc7: Reported regressions from 2.6.32
Rafael J. Wysocki
Maciej Rutecki has generously volunteered to work on the tracking of kernel
regressions with me, so now there are two people doing this and I'm going
to call us "the tracking team". Please be friendly to Maciej, he's doing his
best to help. If you have any information about kernel regressions you want
to share with us, please feel free to contact Maciej as well as me.]
This message contains a list of some regressions from 2.6.32,
for which there are no fixes in the mainline known to the tracking team.
If any of them have been fixed already, please let us know.
If you know of any other unresolved regressions from 2.6.32, please let us
know either and we'll add them to the list. Also, please let us know
if any of the entries below are invalid.
Each entry from the list will be sent additionally in an automatic reply
to this message with CCs to the people involved in reporting and handling
the issue.

This type of lock dependency is always going to exist whenever a write to
a sysfs file causes the kernel to remove its dirent. In this case,
writing to /sys/devices/block/xxx/queue/scheduler takes sd->dep_map and
sd->parent->dep_map via sysfs_get_active_two() to pin both via
sysfs_write_file(). The call to kobject_del() removes its directory
from the hierarchy which takes sd->dep_map in sysfs_deactivate() because
of 846f99749a. Eric, do we need to preempt the rwsem from being acquired
here when the dirent is already pinned because of a store to one of its
files?

Yes, it's still present in -rc7.

Hmm. The bug is in net/dccp/ccid.c, so it looks like something for the
networking guys to merge.
Any chance to send a singed-off version of the patch do David?

The regression compared to 2.6.32 is solved in 2.6.33-rc7 for the
specific test mentioned in the Bugzilla entry. The regression compared
to 2.6.28 is not yet solved though, so I'm not sure what should happen
with this bug entry.

I guess it's better to move it to the list of regressions from 2.6.28.

Fixes for this are already in my net-2.6 tree, will send them
off to Linus later today, I was waiting for some netfilter
fixes which I just received:
commit 1386be55e32a3c5d8ef4a2b243c530a7b664c02c
Author: Gerrit Renker <ger...@erg.abdn.ac.uk>
Date: Tue Feb 2 20:16:56 2010 +0000
dccp: fix auto-loading of dccp(_probe)
This fixes commit (38ff3e6bb987ec583268da8eb22628293095d43b) ("dccp_probe:
Fix module load dependencies between dccp and dccp_probe", from 15 Jan).
It fixes the construction of the first argument of try_then_request_module(),
where only valid return codes from the first argument should be returned.
What we do now is assign the result of register_jprobe() to ret, without
the side effect of the comparison.

commit 8ed030dd0aa400d18c63861c2c6deb7c38f4edde
Author: Gerrit Renker <ger...@erg.abdn.ac.uk>
Date: Mon Feb 1 02:12:19 2010 +0000
dccp: fix bug in cache allocation
This fixes a bug introduced in commit de4ef86cfce60d2250111f34f8a084e769f23b16
("dccp: fix dccp rmmod when kernel configured to use slub", 17 Jan): the
vsnprintf used sizeof(slab_name_fmt), which became truncated to 4 bytes, since
slab_name_fmt is now a 4-byte pointer and no longer a 32-character array.
This lead to error messages such as
FATAL: Error inserting dccp: No buffer space available
>> kernel: [ 1456.341501] kmem_cache_create: duplicate cache cci
generated due to the truncation after the 3rd character.
Fixed for the moment by introducing a symbolic constant. Tested to fix the bug.
