kernel weekly news – 17.03.2012

Posted: March 17, 2012 in kernel

Howdy everyone. This week we start with

-Rafael J. Wysocki has renesas SoC updates, and quite a lot, including fixes, L2 cache support for the
r8a7779, and other improvements.

-Linus announces -rc7, as below:

I had been hoping that -rc6 would be the last -rc, but no such luck.
Things just haven’t calmed down sufficiently for me to feel comfy
doing a final 3.3 release without another -rc, so here we are: 3.3-rc7
is out.

Now, none of the fixes here are all that scary in themselves, but
there were just too many of them, and across various subsystems.
Networking, memory management, drivers, you name it. And instead of
having fewer commits than in -rc6, we have more of them. So my hope
that things would calm down simply just didn’t materialize.

I really would prefer not having an -rc8, though. And I do think we’re
in fairly good shape, I just didn’t think we were quite there yet for
a release. Thus this will hopefully *really* be the final -rc.

-Al Viro has vfs updates, Paul Mundt rmobile and sh fixes for -rc8,
Matthew Garrett has platform driver updates for 3.3, Greg KH announces
kernels 3.2.10 and 3.0.24, plus 3.2.11, as a fix for a small bug unnoticed
for .10, John W. Linville has wireless updates in a pull request and
Chris Metcalf has a arch/tile update for 3.3 .

-David Miller has networking updates:

The most important bit here is the TCP syncookies issue, which seems
to have been busted for some time. That fix has been verified in
production by the reporter.

1) Persistent TUN devices erroneously hold on to the network
namespace in such a way that it cannot be shutdown. Fix
from Stanislav Kinsbursky with help from Eric Dumazet.

2) TCP SYN cookies have been broken for a while due to how the route
lookup flow key is managed, connections can be delayed by as much
as 20 seconds due to this bug. Fix from Eric Dumazet.

3) Missing jiffies.h include in lib/dynamic_queue_limits.c can break
the build, from Tom Herbert.

4) Add USB device ID for Sitecom LN-031, from Joerg Neikes.

5) Fix OOPS in delayed workqueue in iwlegacy, from Stanislaw Gruszka.

6) rt2x00 TX queue can be disabled forever due to races, fix by
synchronizing pause/unpause with a lock. Also from Stanislaw

7) Statistics and endian fix in bnx2x driver from Yuval Mintz,
Eilon Greenstein, and Ariel Elior.

-Jens Axboe has block fixes for 3.3, Steven Rostedt has tracing
updates, Arnaldo Carvalho de Melo fixes perf/urgent,
Mauro Carvalho Chehab has 3.3-aimed media fixes and John
Stultz has time/clocksource/rtc fixes.

-That’s it for this week. Have a nice weekend.
