2006-04-19RPCSEC_GSS: fix leak in krb5 code caused by superfluous kmallocJ. Bruce Fields
I was sloppy when generating a previous patch; I modified the callers of krb5_make_checksum() to allocate memory for the buffer where the result is returned, then forgot to modify krb5_make_checksum to stop allocating that memory itself. The result is a per-packet memory leak. This fixes the problem by removing the now-superfluous kmalloc(). Signed-off-by: J.

2006-04-18[IPV6] XFRM: Fix decoding session with preceding extension header(s).YOSHIFUJI Hideaki
We did not correctly decode session with preceding extension header(s). This was because we had already pulled preceding headers, skb->nh.raw + 40 + 1 - skb->data was minus, and pskb_may_pull() failed. We now have IP6CB(skb)->nhoff and skb->h.raw, and we can start parsing / decoding upper layer protocol from current position.

2006-04-18[TCP]: Fix truesize underflowHerbert Xu
There is a problem with the TSO packet trimming code. The cause of this lies in the tcp_fragment() function. When we allocate a fragment for a completely non-linear packet the truesize is calculated for a payload length of zero. This means that truesize could in fact be less than the real payload length. When that happens the TSO packet trimming can cause truesize to become negative. This in turn can cause sk_forward_alloc to be -n * PAGE_SIZE which would trigger the warning. I've copied the code DaveM used in tso_fragment which should work here. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-04-17[IPV4]: ip_route_input panic fixStephen Hemminger
This fixes http://bugzilla.kernel.org/show_bug.cgi?id=6388 The bug is caused by ip_route_input dereferencing skb->nh.protocol of the dummy skb passed dow from inet_rtm_getroute (Thanks Thomas for seeing it).

2006-04-14[ATM]: clip causes unregister hangStephen Hemminger
If Classical IP over ATM module is loaded, its neighbor table gets populated when permanent neighbor entries are created; but these entries are not flushed when the device is removed. Since the entry never gets flushed the unregister of the network device never completes. This version of the patch also adds locking around the reference to the atm arp daemon to avoid races with events and daemon state changes.

This closes a race where an ipq6hashfn() caller could get a hash value and race with the cycling of the random seed.

for_each_cpu() actually iterates across all possible CPUs.
