[IPSEC] flow: Fix potential memory leak

2007-01-24T04:25:39+00:00

When old flow cache entries that are not at the head of their chain
trigger a transient security error they get unlinked along with all
the entries preceding them in the chain.  The preceding entries are
not freed correctly.

This patch fixes this by simply leaving the entry around.  It's based
on a suggestion by Venkat Yekkirala.

[PKTGEN]: Convert to kthread API.

Based upon a suggestion from Christoph Hellwig.

This fixes various races in module load/unload handling
too.

[PATCH] netpoll: fix netpoll lockup

2006-12-12T16:37:51+00:00

current -git doesnt boot on my laptop due to netpoll not unlocking the
tx lock in the else branch.

booted this up on my laptop with lockdep enabled and there are no
locking complaints and it works fine.

Herbert sayeth:

  Normally networking isn't invoked with interrupts turned off, but I
  suppose we don't have a choice here.  This is unique being a place where you
  can get called with BH on, off, or IRQs off.

  Given that this is only used for printk, the easiest solution is probably
  just to disable local IRQs instead of BH.

[NETPOLL]: make arp replies through netpoll use mac address of sender

2006-12-09T01:19:28+00:00

Back in 2.4 arp requests that were recevied by netpoll were processed
in netconsole_receive_skb, where they were responded to using the src
mac of the request sender.  In the 2.6 kernel arp_reply is responsible
for this function, but instead of using the src mac address of the
incomming request, the stored mac address that was registered for the
netconsole application is used.  While this is usually ok, it can lead
to failures in netpoll in some situations (specifically situations
where a network may have two gateways, as arp requests from one may be
responded to using the mac address of the other).  This patch reverts
the behavior to what we had in 2.4, in which all arp requests are sent
back using the src address of the request sender.

[NET]: Convert hh_lock to seqlock.

2006-12-09T01:19:20+00:00

The hard header cache is in the main output path, so using
seqlock instead of reader/writer lock should reduce overhead.

[PATCH] hotplug CPU: clean up hotcpu_notifier() use

2006-12-07T16:39:39+00:00

There was lots of #ifdef noise in the kernel due to hotcpu_notifier(fn,
prio) not correctly marking 'fn' as used in the !HOTPLUG_CPU case, and thus
generating compiler warnings of unused symbols, hence forcing people to add
#ifdefs.

the compiler can skip truly unused functions just fine:

    text    data     bss     dec     hex filename

[PATCH] lockdep: annotate nfs/nfsd in-kernel sockets

2006-12-07T16:39:30+00:00

Stick NFS sockets in their own class to avoid some lockdep warnings.  NFS
sockets are never exposed to user-space, and will hence not trigger certain
code paths that would otherwise pose deadlock scenarios.
