If a socket starts out on a non-TSO route, and then switches to a TSO route, then the tail on the tx queue can morph into a TSO packet, causing mischief because the rest of the stack does not expect a partially linear TSO packet. This patch fixes this by ensuring that skb->ip_summed is set to CHECKSUM_PARTIAL before declaring a packet as TSO.

When NAT helpers change the TCP packet size, the highest seen sequence number needs to be corrected. This is currently only done upwards, when the packet size is reduced the sequence number is unchanged. This causes TCP conntrack to falsely detect unacknowledged data and decrease the timeout. Fix by updating the highest seen sequence number in both directions after packet mangling. Tested-by: NKrzysztof Piotr Oledzki <ole@ans.pl> Signed-off-by: NPatrick McHardy <kaber@trash.net>

While testing the driver on PPC, we ran into a crash with LRO, Jumbo frames. With CONFIG_PPC_64K_PAGES configured (a default in PPC), MAX_SKB_FRAGS drops to 3 and we were crossing the array limits on skb_shinfo(skb)->frags[]. Now we coalesce the frags from the same physical page into one slot in skb_shinfo(skb)->frags[] and go to the next index when the frag is from different physical page. This patch is against the net-2.6 tree. Signed-off-by: NAjit Khaparde <ajitk@serverengines.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

When NAPI is disabled while we're in net_rx_action, we end up calling __napi_complete without flushing GRO packets. This is a bug as it would cause the GRO packets to linger, of course it also literally BUGs to catch error like this :) This patch changes it to napi_complete, with the obligatory IRQ reenabling. This should be safe because we've only just disabled IRQs and it does not materially affect the test conditions in between.

RCU barriers, rcu_barrier(), is inserted two places. In nf_conntrack_expect.c nf_conntrack_expect_fini() before the kmem_cache_destroy(). Firstly to make sure the callback to the nf_ct_expect_free_rcu() code is still around. Secondly because I'm unsure about the consequence of having in flight nf_ct_expect_free_rcu/kmem_cache_free() calls while doing a kmem_cache_destroy() slab destroy. And in nf_conntrack_extend.c nf_ct_extend_unregister(), inorder to wait for completion of callbacks to __nf_ct_ext_free_rcu(), which is invoked by __nf_ct_ext_add(). It might be more efficient to call rcu_barrier() in nf_conntrack_core.c nf_conntrack_cleanup_net(), but thats make it more difficult to read the code (as the callback code in located in nf_conntrack_extend.c).

This reverts commit ae0e8e82. This change had two problems: 1) Since it frees the stats in the drivers' close method, we can OOPS in the transmit routine. 2) stats are no longer remembered across ifdown/ifup which disagrees with how every other device operates.

* 'futexes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: futex: Fix the write access fault problem for real
-
由 Thomas Gleixner 提交于
commit 64d1304a (futex: setup writeable mapping for futex ops which modify user space data) did address only half of the problem of write access faults. The patch was made on two wrong assumptions: 1) access_ok(VERIFY_WRITE,...) would actually check write access. On x86 it does _NOT_. It's a pure address range check. 2) a RW mapped region can not go away under us. That's wrong as well. Nobody can prevent another thread to call mprotect(PROT_READ) on that region where the futex resides. If that call hits between the get_user_pages_fast() verification and the actual write access in the atomic region we are toast again. The solution is to not rely on access_ok and get_user() for any write access related fault on private and shared futexes. Instead we need to fault it in with verification of write access. There is no generic non destructive write mechanism which would fault the user page in trough a #PF, but as we already know that we will fault we can as well call get_user_pages() directly and avoid the #PF overhead. If get_user_pages() returns -EFAULT we know that we can not fix it anymore and need to bail out to user space. Remove a bunch of confusing comments on this issue as well.
