2.6.30-rc7: Reported regressions from 2.6.29

2.6.30-rc7: Reported regressions from 2.6.29

[Rafael J. Wysocki]

[NOTE:
 Bug entries for which I know there are working patches get the
 RESOLVED / PATCH_ALREADY_AVAILABLE status in the Bugzilla, which
 makes it easier to check if the patches have been merged before sending
 out the list.  For this reason, please let me know of working patches
 for any of the regression list items or (better) change the status of the bug
 entries in case you know of a working patch (in which case please also add
 a link to the patch to the appropriate bug entry).]

This message contains a list of some regressions from 2.6.29, for which there
are no fixes in the mainline I know of.  If any of them have been fixed already,
please let me know.

If you know of any other unresolved regressions from 2.6.29, please let me know
either and I'll add them to the list.  Also, please let me 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.

I've tested on the latest rc7 kernel and can now boot into the X with
KMS enabled. I believe that's probably good enough for this regression
to be cleared.

I still have some issues with KMS enabled which means it shouldn't be
made a default for intel just yet however I'm not sure where the
problem lie between kernel, X and apps. Compared to a none KMS system
(same xorg.conf, same kernel):

1. GDM gets confused about screen sizes and comes up 1440x900 instead
of stretching the screen to 1680x1050. However the X session itself
gets the right size.

2. Full screen video freezes X. At this point I cannot switch to VT
and need to ssh in to kill and restore X. The logs/dmesg are fairly
mute as to why though.

3. Performance seems to be lower. The compiz benchmark happily report
120fps without KMS on my normal display and around 60FPS with it
enabled. Some displays (like the big wall plugin) the difference is
less marked (14FPS to 9FPS).

I've also seen some oopses occur while running:

sorry for not mentioning this before, but it looks like this regression
was introduced between .28 and .29

The proposed patch has yet to be ACKed by the maintainer/merged, so
yes, this regression should still be listed.

Bug was present in 2.6.29, so its a regression from 2.6.28

It is solved and available in David tree (net-2.6), and scheduled for stable submission

commit 1ddbcb005c395518c2cd0df504cff3d4b5c85853
net: fix rtable leak in net/ipv4/route.c

Alexander V. Lukyanov found a regression in 2.6.29 and made a complete
analysis found in http://bugzilla.kernel.org/show_bug.cgi?id=13339
Quoted here because its a perfect one :

begin_of_quotation
 2.6.29 patch has introduced flexible route cache rebuilding. Unfortunately the
 patch has at least one critical flaw, and another problem.

 rt_intern_hash calculates rthi pointer, which is later used for new entry
 insertion. The same loop calculates cand pointer which is used to clean the
 list. If the pointers are the same, rtable leak occurs, as first the cand is
 removed then the new entry is appended to it.

 This leak leads to unregister_netdevice problem (usage count > 0).

 Another problem of the patch is that it tries to insert the entries in certain
 order, to facilitate counting of entries distinct by all but QoS parameters.
 Unfortunately, referencing an existing rtable entry moves it to list beginning,
 to speed up further lookups, so the carefully built order is destroyed.

 For the first problem the simplest patch it to set rthi=0 when rthi==cand, but
 it will also destroy the ordering.
end_of_quotation

Problematic commit is 1080d709fb9d8cd4392f93476ee46a9d6ea05a5b
(net: implement emergency route cache rebulds when gc_elasticity is exceeded)

Trying to keep dst_entries ordered is too complex and breaks the fact that
order should depend on the frequency of use for garbage collection.

A possible fix is to make rt_intern_hash() simpler, and only makes
rt_check_expire() a litle bit smarter, being able to cope with an arbitrary
entries order. The added loop is running on cache hot data, while cpu
is prefetching next object, so should be unnoticied.
