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. Signed-off-by:

Change get_tx_queues, drop unsused arg/return value real_tx_queues, and use return by value (with error) rather than call by reference. Probably bonding should just change to LLTX and the whole get_tx_queues API could disappear! Signed-off-by:

In ancient times it was necessary to manually initialize the bus field of an spi_driver to spi_bus_type. These days this is done in spi_driver_register() so we can drop the manual assignment.

The comparison operators were backwards in both garp_attr_lookup and garp_attr_create, so the entire GID rbtree was in reverse order. (There was no practical side effect to this though, except that PDUs were sent with attributes listed in reverse order, which is still valid by the protocol. This change is only for clarity.)

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.) Signed-off-by:

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.

We already synthesize events in register_netdevice_notifier and synthesizing events in unregister_netdevice_notifier allows to us remove the need for special case cleanup code. This change should be safe as it adds no new cases for existing callers of unregiser_netdevice_notifier to handle. Signed-off-by:

Added strict checking of PadN, as PadN can be used to increase header size and thus push the protocol header into the 2nd fragment. 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. RFC 4942 recommends to actively check the "payload" itself and ensure that it contains only zeroes. See also RFC 4942 section 2.1.9.5. Signed-off-by:

Pull networking fixes from David Miller: 1) Fix bluetooth userland regression reported by Keith Packard, from Gustavo Padovan. 2) Revert ath9k PS idle change, from Sujith Manoharan. 3) Correct default TCP memory limits (again), from Eric Dumazet. 4) Fix tcp_rcv_rtt_update() accidental use of unscaled RTT, from Neal Cardwell. 5) We made a facility for layers like wireless to say how much tailroom they need in the SKB for link layer stuff such as wireless encryption etc., but TCP works hard to fill every SKB out to the end defeating this specification. This leads to every TCP packet getting reallocated by the wireless code in order to have the right amount of tailroom available. Fix TCP to only fill SKBs out to the real amount of data area it asked for during the allocation, this way it won't eat into the slack added for the device's tailroom needs. Reported by Marc Merlin and fixed by Eric Dumazet. 6) Leaks, endian bugs, and new device IDs in bluetooth from Santosh Nayak, João Paulo Rechi Vita, Cho, Yu-Chen, Andrei Emeltchenko, AceLan Kao, and Andrei Emeltchenko. 7) OOPS on tty_close fix in bluetooth's hci_ldisc from Johan Hovold. 8) netfilter erroneously scales TCP window twice, fix from Changli Gao. 9) Memleak fix in wext-core from Julia Lawall. 10) Consistently handle invalid TCP packets in ipv4 vs. ipv6 conntrack, from Jozsef Kadlecsik. 11) Validate IP header length properly in netfilter conntrack's ipv4_get_l4proto(). * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (39 commits) NFC: Fix the LLCP Tx fragmentation loop rtlwifi: Add missing DMA buffer unmapping for PCI drivers rtlwifi: Preallocate USB read buffers and eliminate kalloc in read routine tcp: avoid order-1 allocations on wifi and tx path net: allow pskb_expand_head() to get maximum tailroom bridge: Do not send queries on multicast group leaves MAINTAINERS: Mark NATSEMI driver as orphan'd. tcp: fix tcp_rcv_rtt_update() use of an unscaled RTT sample tcp: restore correct limit Revert "ath9k: fix going to full-sleep on PS idle" rt2x00: Fix rfkill_polling register function. bcma: fix build error on MIPS; implicit pcibios_enable_device netfilter: nf_conntrack: fix incorrect logic in nf_conntrack_init_net netfilter: nf_ct_ipv4: packets with wrong ihl are invalid netfilter: nf_ct_ipv4: handle invalid IPv4 and IPv6 packets consistently net/wireless/wext-core.c: add missing kfree rtlwifi: Fix oops on rate-control failure mac80211: Convert WARN_ON to WARN_ON_ONCE rtlwifi: rtl8192de: Fix firmware initialization nl80211: ensure interface is up in various APIs ... -
