Pull networking update from David Miller: 1) Checkpoint/restarted TCP sockets now can properly propagate the TCP timestamp offset. From Andrey Vagin. 2) VMWARE VM VSOCK layer, from Andy King. 3) Much improved support for virtual functions and SR-IOV in bnx2x, from Ariel ELior. 4) All protocols on ipv4 and ipv6 are now network namespace aware, and all the compatability checks for initial-namespace-only protocols is removed. Thanks to Tom Parkin for helping deal with the last major holdout, L2TP. 5) IPV6 support in netpoll and network namespace support in pktgen, from Cong Wang. 6) Multiple Registration Protocol (MRP) and Multiple VLAN Registration Protocol (MVRP) support, from David Ward. 7) Compute packet lengths more accurately in the packet scheduler, from Eric Dumazet. 8) Use per-task page fragment allocator in skb_append_datato_frags(), also from Eric Dumazet. 9) Add support for connection tracking labels in netfilter, from Florian Westphal. 10) Fix default multicast group joining on ipv6, and add anti-spoofing checks to 6to4 and 6rd. From Hannes Frederic Sowa. 11) Make ipv4/ipv6 fragmentation memory limits more reasonable in modern times, rearrange inet frag datastructures for better cacheline locality, and move more operations outside of locking. From Jesper Dangaard Brouer. 12) Instead of strict master <--> slave relationships, allow arbitrary scenerios with "upper device lists". From Jiri Pirko. 13) Improve rate limiting accuracy in TBF and act_police, also from Jiri Pirko. 14) Add a BPF filter netfilter match target, from Willem de Bruijn. 15) Orphan and delete a bunch of pre-historic networking drivers from Paul Gortmaker. 16) Add TSO support for GRE tunnels, from Pravin B SHelar. Although this still needs some minor bug fixing before it's %100 correct in all cases. 17) Handle unresolved IPSEC states like ARP, with a resolution packet queue. From Steffen Klassert. 18) Remove TCP Appropriate Byte Count support (ABC), from Stephen Hemminger. This was long overdue. 19) Support SO_REUSEPORT, from Tom Herbert. 20) Allow locking a socket BPF filter, so that it cannot change after a process drops capabilities. 21) Add VLAN filtering to bridge, from Vlad Yasevich. 22) Bring ipv6 on-par with ipv4 and do not cache neighbour entries in the ipv6 routes, from YOSHIFUJI Hideaki. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1538 commits) ipv6: fix race condition regarding dst->expires and dst->from. net: fix a wrong assignment in skb_split() ip_gre: remove an extra dst_release() ppp: set qdisc_tx_busylock to avoid LOCKDEP splat atl1c: restore buffer state net: fix a build failure when !CONFIG_PROC_FS net: ipv4: fix waring -Wunused-variable net: proc: fix build failed when procfs is not configured Revert "xen: netback: remove redundant xenvif_put" net: move procfs code to net/core/net-procfs.c qmi_wwan, cdc-ether: add ADU960S bonding: set sysfs device_type to 'bond' bonding: fix bond_release_all inconsistencies b44: use netdev_alloc_skb_ip_align() xen: netback: remove redundant xenvif_put net: fec: Do a sanity check on the gpio number ip_gre: propogate target device GSO capability to the tunnel device ip_gre: allow CSUM capable devices to handle packets bonding: Fix initialize after use for 3ad machine state spinlock bonding: Fix race condition between bond_enslave() and bond_3ad_update_lacp_rate() ...

Revert "of: use platform_device_add"

2013-02-17T20:03:27Z

This reverts commit aac73f34542bc7ae4317928d2eabfeb21d247323. That commit causes two kinds of breakage; it breaks registration of AMBA devices when one of the parent nodes already contains overlapping resource regions, and it breaks calls to request_region() by device drivers in certain conditions where there are overlapping memory regions. Both of these problems can probably be fixed, but it is better to back out the commit and get a proper fix designed before trying again. Signed-off-by: Grant Likely

of: Create function for counting number of phandles in a property

2013-02-13T10:09:31Z

This patch creates of_count_phandle_with_args(), a new function for counting the number of phandle+argument tuples in a given property. This is better than the existing method of parsing each phandle individually until parsing fails which is a horribly slow way to do the count. Tested on ARM using the selftest code. v3: - Rebased on top of selftest code cleanup patch v2: - fix bug where of_parse_phandle_with_args() could behave like _count_. - made of_gpio_named_count() into a static inline regardless of CONFIG_OF_GPIO Tested-by: Andreas Larsson Signed-off-by: Grant Likely Cc: Linus Walleij Cc: Rob Herring

of/base: Clean up exit paths for of_parse_phandle_with_args()

2013-02-13T10:05:58Z

Some of the exit paths were not correctly releasing the node. Fix it by creating an 'err' label for collecting the error paths and releasing the node. Cc: Rob Herring Signed-off-by: Grant Likely

of/selftest: Use selftest() macro throughout

2013-02-13T10:05:58Z

Some of the selftests are open-coded. Others use the selftest() macro defined in drivers/of/selftest.c. The macro makes for cleaner selftest code, so refactor the of_parse_phandle_with_args() tests to use it. Cc: Rob Herring Signed-off-by: Grant Likely

of/selftest: Fix GPIOs selftest to cover the 7th case

2013-02-13T10:05:57Z

The of_gpio_named_count() self test doesn't hit the out-of-range condition even though it is coded. Fix the bug by increasing the for loop range by one. Reported-by: Andreas Larsson Cc: Rob Herring Signed-off-by: Grant Likely

of: fix recursive locking in of_get_next_available_child()

2013-02-13T10:05:24Z

of_get_next_available_child() acquires devtree_lock, then calls of_device_is_available() which calls of_get_property() which calls of_find_property() which tries to re-acquire devtree_lock, thus causing deadlock. To avoid this, create a new __of_device_is_available() which calls __of_get_property() instead, which calls __of_find_property(), which does not take the lock,. Update of_get_next_available_child() to call the new __of_device_is_available() since it already owns the lock. Signed-off-by: Stephen Warren Signed-off-by: Grant Likely

OF: convert devtree lock from rw_lock to raw spinlock

2013-02-08T23:02:40Z

With the locking cleanup in place (from "OF: Fixup resursive locking code paths"), we can now do the conversion from the rw_lock to a raw spinlock as required for preempt-rt. The previous cleanup and this conversion were originally separate since they predated when mainline got raw spinlock (in commit c2f21ce2e31286a "locking: Implement new raw_spinlock"). So, at that point in time, the cleanup was considered plausible for mainline, but not this conversion. In any case, we've kept them separate as it makes for easier review and better bisection.
