2008-08-18netfilter: ctnetlink: sleepable allocation with spin lock bhPablo Neira Ayuso
This patch removes a GFP_KERNEL allocation while holding a spin lock with bottom halves disabled in ctnetlink_change_helper(). This problem was introduced in 2.6.23 with the netfilter extension infrastructure.

2008-08-18netfilter: ctnetlink: fix double helper assignation for NAT'ed conntracksPablo Neira Ayuso
If we create a conntrack that has NAT handlings and a helper, the helper is assigned twice. This happens because nf_nat_setup_info() - via nf_conntrack_alter_reply() - sets the helper before ctnetlink, which indeed does not check if the conntrack already has a helper as it thinks that it is a brand new conntrack. The fix moves the helper assignation before the set of the status flags. This avoids a bogus assertion in __nf_ct_ext_add (if netfilter assertions are enabled) which checks that the conntrack must not be confirmed. This problem was introduced in 2.6.23 with the netfilter extension infrastructure. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: Patrick McHardy <kaber@trash.net>

2008-08-18dccp: Fix panic caused by too early termination of retransmission mechanismGerrit Renker
Thanks is due to Wei Yongjun for the detailed analysis and description of this bug at http://marc.info/?l=dccp&m=121739364909199&w=2 The problem is that invalid packets received by a client in state REQUEST cause the retransmission timer for the DCCP-Request to be reset. This includes freeing the Request-skb ( in dccp_rcv_request_sent_state_process() ). As a consequence, * the arrival of further packets cause a double-free, triggering a panic(), * the connection then may hang, since further retransmissions are blocked. This patch changes the order of statements so that the retransmission timer is reset, and the pending Request freed, only if a valid Response has arrived (or the number of sysctl-retries has been exhausted). Further changes: ---------------- To be on the safe side, replaced __kfree_skb with kfree_skb so that if due to unexpected circumstances the sk_send_head is NULL the WARN_ON is used instead.

2008-08-18pkt_sched: Don't hold qdisc lock over qdisc_destroy().David S. Miller
Based upon reports by Denys Fedoryshchenko, and feedback and help from Jarek Poplawski and Herbert Xu. We always either: 1) Never made an external reference to this qdisc. or 2) Did a dev_deactivate() which purged all asynchronous references. So do not lock the qdisc when we call qdisc_destroy(), it's illegal anyways as when we drop the lock this is free'd memory. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-18pkt_sched: Add lockdep annotation for qdisc locksJarek Poplawski
Qdisc locks are initialized in the same function, qdisc_alloc(), so lockdep can't distinguish tx qdisc lock from rx and reports "possible recursive locking detected" when both these locks are taken eg. while using act_mirred with ifb. This looks like a false positive. Anyway, after this patch these locks will be reported more exactly.

But, we must not forget to set the skb's data pointers into the same state in which it was initialized by p54u_init_urbs. Otherwise we either end up with 16 bytes less on every requeue, or if a new frame is worthy enough to be accepted, the data is in the wrong place (urb->transfer_buffer wasn't updated!) and mac80211 has a hard time to recognize it...

2008-08-15loopback: Drop obsolete ip_summed settingHerbert Xu
Now that the network stack can handle inbound packets with partial checksums, we should no longer clobber the ip_summed field in the loopback driver. This is because CHECKSUM_UNNECESSARY implies that the checksum field is actually valid which is not true for loopback packets since it's only partial (and thus complemented). This allows packets from lo to then be SNATed to an external source while still preserving the checksum's validity. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2008-08-15tg3: Fix firmware event timeoutsMatt Carlson
The git commit 7c5026aa9b81dd45df8d3f4e0be73e485976a8b6 ("tg3: Add link state reporting to UMP firmware") introduced code that waits for previous firmware events to be serviced before attempting to submit a new event. Unfortunately that patch contained a bug that cause the driver to wait 2.5 seconds, rather than 2.5 milliseconds as intended. This patch fixes that bug. This bug revealed that not all firmware versions service driver events though. Since we do not know which versions of the firmware do and don't service these events, the driver needs some way to minimize the effects of the delay. This patch solves the problem by recording a jiffies timestamp when it submits an event to the hardware. If the jiffies counter shows that 2.5 milliseconds have already passed, a wait is not needed and the driver can proceed to submit a new event.
