Pull networking fixes from David Miller: "A moderately sized pile of fixes, some specifically for merge window introduced regressions although others are for longer standing items and have been queued up for -stable. I'm kind of tired of all the RDS protocol bugs over the years, to be honest, it's way out of proportion to the number of people who actually use it. 1) Fix missing range initialization in netfilter IPSET, from Jozsef Kadlecsik. 2) ieee80211_local->tim_lock needs to use BH disabling, from Johannes Berg. 3) Fix DMA syncing in SFC driver, from Ben Hutchings. 4) Fix regression in BOND device MAC address setting, from Jiri Pirko. 5) Missing usb_free_urb in ISDN Hisax driver, from Marina Makienko. 6) Fix UDP checksumming in bnx2x driver for 57710 and 57711 chips, fix from Dmitry Kravkov. 7) Missing cfgspace_lock initialization in BCMA driver. 8) Validate parameter size for SCTP assoc stats getsockopt(), from Guenter Roeck. 9) Fix SCTP association hangs, from Lee A Roberts. 10) Fix jumbo frame handling in r8169, from Francois Romieu. 11) Fix phy_device memory leak, from Petr Malat. 12) Omit trailing FCS from frames received in BGMAC driver, from Hauke Mehrtens. 13) Missing socket refcount release in L2TP, from Guillaume Nault. 14) sctp_endpoint_init should respect passed in gfp_t, rather than use GFP_KERNEL unconditionally. From Dan Carpenter. 15) Add AISX AX88179 USB driver, from Freddy Xin. 16) Remove MAINTAINERS entries for drivers deleted during the merge window, from Cesar Eduardo Barros. 17) RDS protocol can try to allocate huge amounts of memory, check that the user's request length makes sense, from Cong Wang. 18) SCTP should use the provided KMALLOC_MAX_SIZE instead of it's own, bogus, definition. From Cong Wang. 19) Fix deadlocks in FEC driver by moving TX reclaim into NAPI poll, from Frank Li. Also, fix a build error introduced in the merge window. 20) Fix bogus purging of default routes in ipv6, from Lorenzo Colitti. 21) Don't double count RTT measurements when we leave the TCP receive fast path, from Neal Cardwell." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (61 commits) tcp: fix double-counted receiver RTT when leaving receiver fast path CAIF: fix sparse warning for caif_usb rds: simplify a warning message net: fec: fix build error in no MXC platform net: ipv6: Don't purge default router if accept_ra=2 net: fec: put tx to napi poll function to fix dead lock sctp: use KMALLOC_MAX_SIZE instead of its own MAX_KMALLOC_SIZE rds: limit the size allocated by rds_message_alloc() MAINTAINERS: remove eexpress MAINTAINERS: remove drivers/net/wan/cycx* MAINTAINERS: remove 3c505 caif_dev: fix sparse warnings for caif_flow_cb ax88179_178a: ASIX AX88179_178A USB 3.0/2.0 to gigabit ethernet adapter driver sctp: use the passed in gfp flags instead GFP_KERNEL ipv[4|6]: correct dropwatch false positive in local_deliver_finish l2tp: Restore socket refcount when sendmsg succeeds net/phy: micrel: Disable asymmetric pause for KSZ9021 bgmac: omit the fcs phy: Fix phy_device_free memory leak bnx2x: Fix KR2 work-around condition ...

2013-03-03ax88179_178a: ASIX AX88179_178A USB 3.0/2.0 to gigabit ethernet adapter driverFreddy Xin3-0/+1467
This is a resubmission. Added kfree() in ax88179_get_eeprom to prevent memory leakage. Modified "__le16 rxctl" to "u16 rxctl" in "struct ax88179_data" and removed pointless casts. Removed asix_init and asix_exit functions and added "module_usb_driver(ax88179_178a_driver)". Fixed endianness issue on big endian systems and verified this driver on iBook G4. Removed steps that change net->features in ax88179_set_features function. Added "const" to ethtool_ops structure and fixed the coding style of AX88179_BULKIN_SIZE array. Fixed the issue that the default MTU is not 1500. Added ax88179_change_mtu function and enabled the hardware jumbo frame function to support an MTU higher than 1500. Fixed indentation and empty line coding style errors. The _nopm version usb functions were added to access register in suspend and resume functions. Serveral variables allocted dynamically were removed and replaced by stack variables. ax88179_get_eeprom were modified from asix_get_eeprom in asix_common. This patch adds a driver for ASIX's AX88179 family of USB 3.0/2.0 to gigabit ethernet adapters. It's based on the AX88xxx driver but the usb commands used to access registers for AX88179 are completely different. This driver had been verified on x86 system with AX88179/AX88178A and Sitcomm LN-032 USB dongles. Signed-off-by: Freddy Xin <freddy@asix.com.tw> Signed-off-by: David S. Miller <davem@davemloft.net>

Pull MIPS updates from Ralf Baechle: o Add basic support for the Mediatek/Ralink Wireless SoC family. o The Qualcomm Atheros platform is extended by support for the new QCA955X SoC series as well as a bunch of patches that get the code ready for OF support. o Lantiq and BCM47XX platform have a few improvements and bug fixes. o MIPS has sent a few patches that get the kernel ready for the upcoming microMIPS support. o The rest of the series is made up of small bug fixes and cleanups that relate to various parts of the MIPS code. The biggy in there is a whitespace cleanup. After I was sent another set of whitespace cleanup patches I decided it was the time to clean the whitespace "issues" for once and and that touches many files below arch/mips/. Fix up silly conflicts, mostly due to whitespace cleanups. * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (105 commits) MIPS: Quit exporting kernel internel break codes to uapi/asm/break.h MIPS: remove broken conditional inside vpe loader code MIPS: SMTC: fix implicit declaration of set_vi_handler MIPS: early_printk: drop __init annotations MIPS: Probe for and report hardware virtualization support.

2013-02-28phy: Fix phy_device_free memory leakPetr Malat1-4/+6
Fix memory leak in phy_device_free() for the case when phy_device* returned by phy_device_create() is not registered in the system. Bug description: phy_device_create() sets name of kobject using dev_set_name(), which allocates memory using kvasprintf(), but this memory isn't freed if the underlying device isn't registered properly, because kobject_cleanup() is not called in that case. This can happen (and actually is happening on our machines) if phy_device_register(), called by mdiobus_scan(), fails. Patch description: Embedded struct device is initialized in phy_device_create() and it counterpart phy_device_free() just drops one reference to the device, which leads to proper deinitialization including releasing the kobject name memory.

2013-02-27hlist: drop the node parameter from iteratorsSasha Levin11-60/+50
I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually. The semantic patch which is mostly the work of Peter Senna Tschudin is here: @@ iterator name hlist_for_each_entry, hlist_for_each_entry_continue, hlist_for_each_entry_from, hlist_for_each_entry_rcu, hlist_for_each_entry_rcu_bh, hlist_for_each_entry_continue_rcu_bh, for_each_busy_worker, ax25_uid_for_each, ax25_for_each, inet_bind_bucket_for_each, sctp_for_each_hentry, sk_for_each, sk_for_each_rcu, sk_for_each_from, sk_for_each_safe, sk_for_each_bound, hlist_for_each_entry_safe, hlist_for_each_entry_continue_rcu, nr_neigh_for_each, nr_neigh_for_each_safe, nr_node_for_each, nr_node_for_each_safe, for_each_gfn_indirect_valid_sp, for_each_gfn_sp, for_each_host; type T; expression a,c,d,e; identifier b; statement S; @@ -T b; <+... when != b ( hlist_for_each_entry(a, - b, c, d) S | hlist_for_each_entry_continue(a, - b, c) S | hlist_for_each_entry_from(a, - b, c) S | hlist_for_each_entry_rcu(a, - b, c, d) S | hlist_for_each_entry_rcu_bh(a, - b, c, d) S | hlist_for_each_entry_continue_rcu_bh(a, - b, c) S | for_each_busy_worker(a, c, - b, d) S | ax25_uid_for_each(a, - b, c) S | ax25_for_each(a, - b, c) S | inet_bind_bucket_for_each(a, - b, c) S | sctp_for_each_hentry(a, - b, c) S | sk_for_each(a, - b, c) S | sk_for_each_rcu(a, - b, c) S | sk_for_each_from -(a, b) +(a) S + sk_for_each_from(a) S | sk_for_each_safe(a, - b, c, d) S | sk_for_each_bound(a, - b, c) S | hlist_for_each_entry_safe(a, - b, c, d, e) S | hlist_for_each_entry_continue_rcu(a, - b, c) S | nr_neigh_for_each(a, - b, c) S | nr_neigh_for_each_safe(a, - b, c, d) S | nr_node_for_each(a, - b, c) S | nr_node_for_each_safe(a, - b, c, d) S | - for_each_gfn_sp(a, c, d, b) S + for_each_gfn_sp(a, c, d) S | - for_each_gfn_indirect_valid_sp(a, c, d, b) S + for_each_gfn_indirect_valid_sp(a, c, d) S | for_each_host(a, - b, c) S | for_each_host_safe(a, - b, c, d) S | for_each_mesh_entry(a, - b, c, d) S ) ...+> [akpm@linux-foundation.org: drop bogus change from net/ipv4/raw.c] [akpm@linux-foundation.org: drop bogus hunk from net/ipv6/raw.c] [akpm@linux-foundation.org: checkpatch fixes] [akpm@linux-foundation.org: fix warnings] [akpm@linux-foudnation.org: redo intrusive kvm changes] Tested-by: Peter Senna Tschudin <peter.senna@gmail.com> Acked-by: Paul E.

2013-02-27ath9k_hw: improve reset reliability after errorsFelix Fietkau1-1/+3
On many different chips, important aspects of the MAC state are not fully cleared by a warm reset. This can show up as tx/rx hangs, those annoying "DMA failed to stop in 10 ms..." messages or other quirks. On AR933x, the chip can occasionally get stuck in a way that only a driver unload/reload or a reboot would bring it back to life. With this patch, a full reset is issued when bringing the chip out of FULL-SLEEP state (after idle), or if either Rx or Tx was not shut down properly. This makes the DMA related error messages disappear completely in my tests on AR933x, and the chip does not get stuck anymore.

The ath9k commit 2ef167557c0a26c88162ecffb017bfcc51eb7b29 (ath9k: fix signal strength reporting issues) fixed an issue where the reported per-frame signal strength reported to mac80211 was being overwritten with an internal average. The same issue is also present in ath9k_htc. In addition to preventing the driver from overwriting the value, this commit also ensures that the internal average (which is used for ANI) only tracks beacons of the AP that we're connected to.

This USB ethernet adapter was purchased in anodyne packaging from the computer store adjacent to linux.conf.au 2013 in Canberra (Australia). A web search shows other recent purchasers in Lancaster (UK) and Seattle (USA). Just like an emergent virus, our age of e-commerce and airmail allows underdocumented hardware to spread around the world instantly using the vector of ridiculously low prices. Paige Thompson, infected via eBay, discovered that the HG20F9 is a copy of the Asix 88772B; many viruses copy the RNA of other viruses. See Paige's work at <https://github.com/paigeadele/HG20F9>. This patch uses her discovery to update the restructured Asix driver in the current kernel. Just as some viruses inhabit seemingly-healthy cells, the HG20F9 uses the Vendor ID 0x066b assigned to Linksys Inc. For the present there is no clash of Product ID 0x20f9.

2013-02-26iwlwifi: mvm: fix AP/GO mode station removalJohannes Berg1-5/+14
When stations are removed while packets are in the queue, we drain the queues first, and then remove the stations. If this happens in AP mode while the interface is removed the MAC context might be removed from the firmware before we removed the station(s), resulting in a SYSASSERT 3421. This is because we remove the MAC context from the FW in stop_ap(), but only flush the station drain work later in remove_interface(). Refactor the code a bit to have a common MAC context removal preparation first to solve this.

2013-02-26iwlwifi: always copy first 16 bytes of commandsJohannes Berg3-23/+71
The FH hardware will always write back to the scratch field in commands, even host commands not just TX commands, which can overwrite parts of the command. This is problematic if the command is re-used (with IWL_HCMD_DFL_NOCOPY) and can cause calibration issues. Address this problem by always putting at least the first 16 bytes into the buffer we also use for the command header and therefore make the DMA engine write back into this. For commands that are smaller than 16 bytes also always map enough memory for the DMA engine to write back to.

2013-02-26sfc: Detach net device when stopping queues for reconfigurationBen Hutchings1-4/+12
We must only ever stop TX queues when they are full or the net device is not 'ready' so far as the net core, and specifically the watchdog, is concerned. Otherwise, the watchdog may fire *immediately* if no packets have been added to the queue in the last 5 seconds. The device is ready if all the following are true: (a) It has a qdisc (b) It is marked present (c) It is running (d) The link is reported up (a) and (c) are normally true, and must not be changed by a driver. (d) is under our control, but fake link changes may disturb userland. This leaves (b). We already mark the device absent during reset and self-test, but we need to do the same during MTU changes and ring reallocation. We don't need to do this when the device is brought down because then (c) is already false. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

In addition, add a few safety checks, such as: * Verifying the PD of a new MPT matches the VF. * Making sure binding memory window isn't enabled for FMRs, and that new memory windows are not FMR themselves.
