kernel weekly news – 31.12.2011

Posted: December 31, 2011 in kernel

Hello and welcome to the last edition of the year!

-Arnaldo Carvalho de Melo has perf/core improvements and fixes, David
Miller has a few bug fixes for sparc and networking, and Linus announces
the seventh and last release candidate :

There it is, likely the last -rc in before final 3.2, so please do
check it out in between your holiday festivities.

Most of the changes are faily simple one-liners, but some qla4xxx
driver updates stand out and in fact account for about 40% of the diff
(“qla4xxx: fix flash/ddb support”). That, together with a VMWare DRI
driver update and some dvb updates and the regular random driver fixes
means that 80+% of the changes are in drivers.

Some net updates, some SH updates, and then a (tiny) smattering of
other stuff. The appended shortlog gives the (fairly boring) details,

-Dave Airlie has drm fixes, one for radeon and another for vmwgfx,
Avi Kivity has quite important KVM fixes and David Miller updates
networking:

1) AF_PACKET bind() can leak a netdevice reference, from Wei Yongjun.

2) netem erroneously calls vfree() under spinlock and soft interrupt
disable, fix from Eric Dumazet.

3) ctnetlink_get_expect() can make nfnetlink loop forever when it
returns -EAGAIN in situations where it should not, fix from
Pablo Neira Ayuso.

4) Autoloading connection tracking helpers cannot be done with
spinlocks held because that operation sleeps, fix also from Pablo.

-Ben Myers has an XFS update for 3.2, Sage Weil has ceph fixes, also
for 3.2, and…this is it for this edition, good folks. May you have a happy
new year and see you next year!
