Most machines dont use UDP encapsulation (L2TP) Adds a static_key so that udp_queue_rcv_skb() doesnt have to perform a test if L2TP never setup the encap_rcv on a socket. Idea of this patch came after Simon Horman proposal to add a hook on TCP as well. If static_key is not yet enabled, the fast path does a single JMP . When static_key is enabled, JMP destination is patched to reach the real encap_type/encap_rcv logic, possibly adding cache misses.

The comparison operators were backwards in both garp_attr_lookup and garp_attr_create, so the entire GID rbtree was in reverse order.

We discovered that PPPoATM has an excessively deep transmit queue. A queue the size of the default socket send buffer (wmem_default) is maintained between the PPP generic core and the ATM device. Fix it to queue a maximum of *two* packets. The one the ATM device is currently working on, and one more for the ATM driver to process immediately in its TX done interrupt handler. The PPP core is designed to feed packets to the channel with minimal latency, so that really ought to be enough to keep the ATM device busy. While we're at it, fix the fact that we were triggering the wakeup tasklet on *every* pppoatm_pop() call. The comment saying "this is inefficient, but doing it right is too hard" turns out to be overly pessimistic... I think :) On machines like the Traverse Geos, with a slow Geode CPU and two high-speed ADSL2+ interfaces, there were reports of extremely high CPU usage which could partly be attributed to the extra wakeups. (The wakeup handling could actually be made a whole lot easier if we stop checking sk->sk_sndbuf altogether. Given that we now only queue *two* packets ever, one wonders what the point is. As it is, you could already deadlock the thing by setting the sk_sndbuf to a value lower than the MTU of the device, and it'd just block for ever.)

This was allowing there to be cases when phonenet was not initialized and the phonet net_generic was not set for a network namespace when network device events were being reported on the netdevice_notifier for a network namespace leading to the oops above. 2) phonet_exit_net was implementing a confusing and special case of handling all network devices from going away that it was hard to see was correct, and would only occur when the phonet module was removed. Now that unregister_netdevice_notifier has been modified to synthesize unregistration events for the network devices that are extant when called this confusing special case in phonet_exit_net is no longer needed.

PadN is used to align the options within the Hop-by-Hop or Destination Options header to 64-bit boundaries. The maximum valid size is thus 7 bytes.

Commit 6e6f0a1f ("panic: don't print redundant backtraces on oops") causes a regression where no stack trace will be printed at all for the case where kernel code calls panic() directly while not processing an oops, and of course there are 100's of instances of this type of call. The original commit executed the check (!oops_in_progress), but this will always be false because just before the dump_stack() there is a call to bust_spinlocks(1), which does the following: void __attribute__((weak)) bust_spinlocks(int yes) { if (yes) { ++oops_in_progress; The proper way to resolve the problem that original commit tried to solve is to avoid printing a stack dump from panic() when the either of the following conditions is true: 1) TAINT_DIE has been set (this is done by oops_end()) This indicates and oops has already been printed. 2) oops_in_progress > 1 This guards against the rare case where panic() is invoked a second time, or in between oops_begin() and oops_end() Signed-off-by: NJason Wessel <jason.wessel@windriver.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: <stable@vger.kernel.org> [3.3+] Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
