2008-07-22ipv6: icmp6_dst_gc return changeStephen Hemminger2-8/+5

2008-07-22ipv6: use round_jiffiesStephen Hemminger1-2/+3
This timer normally happens once a minute, there is no need to cause an early wakeup for it, so align it to next second boundary to safe power. It can't be deferred because then it could take too long on cleanup or DoS. Signed-off-by: Stephen Hemminger <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2008-07-21ipv6: use timer pendingStephen Hemminger1-6/+6
This fixes the bridge reference count problem and cleanups ipv6 FIB timer management. Don't use expires field, because it is not a proper way to test, instead use timer_pending(). Signed-off-by: Stephen Hemminger <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2008-07-19tcp: Fix MD5 signatures for non-linear skbsAdam Langley1-44/+83
Currently, the MD5 code assumes that the SKBs are linear and, in the case that they aren't, happily goes off and hashes off the end of the SKB and into random memory. Reported by Stephen Hemminger in [1]. Advice thanks to Stephen and Evgeniy Polyakov. Also includes a couple of missed route_caps from Stephen's patch in [2].

2008-07-08ipv6: fix race between ipv6_del_addr and DAD timerAndrey Vagin1-2/+2
Consider the following scenario: ipv6_del_addr(ifp) ipv6_ifa_notify(RTM_DELADDR, ifp) ip6_del_rt(ifp->rt) after returning from the ipv6_ifa_notify and enabling BH-s back, but *before* calling the addrconf_del_timer the ifp->timer fires and: addrconf_dad_timer(ifp) addrconf_dad_completed(ifp) ipv6_ifa_notify(RTM_NEWADDR, ifp) ip6_ins_rt(ifp->rt) then return back to the ipv6_del_addr and: in6_ifa_put(ifp) inet6_ifa_finish_destroy(ifp) dst_release(&ifp->rt->u.dst) After this we have an ifp->rt inserted into fib6 lists, but queued for gc, which in turn can result in oopses in the fib6_run_gc. Maybe some other nasty things, but we caught only the oops in gc so far. The solution is to disarm the ifp->timer before flushing the rt from it.

2008-06-27inet fragments: fix race between inet_frag_find and inet_frag_secret_rebuildPavel Emelyanov2-1/+4
The problem is that while we work w/o the inet_frags.lock even read-locked the secret rebuild timer may occur (on another CPU, since BHs are still disabled in the inet_frag_find) and change the rnd seed for ipv4/6 fragments. It was caused by my patch fd9e63544cac30a34c951f0ec958038f0529e244 ([INET]: Omit double hash calculations in xxx_frag_intern) late in the 2.6.24 kernel, so this should probably be queued to -stable.

Large Receive Offload (LRO) is only appropriate for packets that are destined for the host, and should be disabled if received packets may be forwarded. It can also confuse the GSO on output. Add dev_disable_lro() function which uses the appropriate ethtool ops to disable LRO if enabled. Add calls to dev_disable_lro() in br_add_if() and functions that enable IPv4 and IPv6 forwarding.
