Pull networking fixes from David Miller: "Some holiday bug fixes for 3.13... There is still one bug I'd like to get fixed before 3.13-final. The vlan code erroneously assignes the header ops of the underlying real device to the VLAN device above it when the real device can hardware offload VLAN handling. That's completely bogus because header ops are tied to the device type, so they only expect to see a 'dev' argument compatible with their ops. The fix is the have the VLAN code use a special set of header ops that does the pass-thru correctly, by calling the underlying real device's header ops but _also_ passing in the real device instead of the VLAN device. That fix is currently waiting some testing. Anyways, of note here: 1) Fix bitmap edge case in radiotap, from Johannes Berg. 2) Fix oops on driver unload in rtlwifi, from Larry Finger. 3) Bonding doesn't do locking correctly during speed/duplex/link changes, from Ding Tianhong. 4) Fix header parsing in GRE code, this bug has been around for a few releases. From Timo Teräs. 5) SIT tunnel driver MTU check needs to take GSO into account, from Eric Dumazet. 6) Minor info leak in inet_diag, from Daniel Borkmann. 7) Info leak in YAM hamradio driver, from Salva Peiró. 8) Fix route expiration state handling in ipv6 routing code, from Li RongQing. 9) DCCP probe module does not check request_module()'s return value, from Wang Weidong. 10) cpsw driver passes NULL device names to request_irq(), from Mugunthan V N. 11) Prevent a NULL splat in RDS binding code, from Sasha Levin. 12) Fix 4G overflow test in tg3 driver, from Nithin Sujir. 13) Cure use after free in arc_emac and fec driver's software timestamp handling, from Eric Dumazet. 14) SIT driver can fail to release the route when iptunnel_handle_offloads() throws an error. From Li RongQing. 15) Several batman-adv fixes from Simon Wunderlich and Antonio Quartulli. 16) Fix deadlock during TIPC socket release, from Ying Xue. 17) Fix regression in ROSE protocol recvmsg() msg_name handling, from Florian Westphal. 18) stmmac PTP support releases wrong spinlock, from Vince Bridgers" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (73 commits) stmmac: Fix incorrect spinlock release and PTP cap detection. phy: IRQ cannot be shared net: rose: restore old recvmsg behavior xen-netback: fix guest-receive-side array sizes fec: Do not assume that PHY reset is active low tipc: fix deadlock during socket release netfilter: nf_tables: fix wrong datatype in nft_validate_data_load() batman-adv: fix vlan header access batman-adv: clean nf state when removing protocol header batman-adv: fix alignment for batadv_tvlv_tt_change batman-adv: fix size of batadv_bla_claim_dst batman-adv: fix size of batadv_icmp_header batman-adv: fix header alignment by unrolling batadv_header batman-adv: fix alignment for batadv_coded_packet netfilter: nf_tables: fix oops when updating table with user chains netfilter: nf_tables: fix dumping with large number of sets ipv6: release dst properly in ipip6_tunnel_xmit netxen: Correct off-by-one errors in bounds checks net: Add some clarification to skb_tx_timestamp() comment. arc_emac: fix potential use after free ...

We've seen so many instances of people invoking skb_tx_timestamp() after the device already has been given the packet, that it's worth being a little bit more verbose and explicit in this comment. Signed-off-by: David S. Miller

Pull libata fixes from Tejun Heo: "There's one interseting commit - "libata, freezer: avoid block device removal while system is frozen". It's an ugly hack working around a deadlock condition between driver core resume and block layer device removal paths through freezer which was made more reproducible by writeback being converted to workqueue some releases ago. The bug has nothing to do with libata but it's just an workaround which is easy to backport. After discussion, Rafael and I seem to agree that we don't really need kernel freezables - both kthread and workqueue. There are few specific workqueues which constitute PM operations and require freezing, which will be converted to use workqueue_set_max_active() instead. All other kernel freezer uses are planned to be removed, followed by the removal of kthread and workqueue freezer support, hopefully. Others are device-specific fixes. The most notable is the addition of NO_NCQ_TRIM which is used to disable queued TRIM commands to Micro M500 SSDs which otherwise suffers data corruption" * 'for-3.13-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: libata, freezer: avoid block device removal while system is frozen libata: implement ATA_HORKAGE_NO_NCQ_TRIM and apply it to Micro M500 SSDs libata: disable a disk via libata.force params ahci: bail out on ICH6 before using AHCI BAR ahci: imx: Explicitly clear IMX6Q_GPR13_SATA_MPLL_CLK_EN libata: add ATA_HORKAGE_BROKEN_FPDMA_AA quirk for Seagate Momentus SpinPoint M8

aio/migratepages: make aio migrate pages sane

2013-12-21T22:56:08+00:00

The arbitrary restriction on page counts offered by the core migrate_page_move_mapping() code results in rather suspicious looking fiddling with page reference counts in the aio_migratepage() operation. To fix this, make migrate_page_move_mapping() take an extra_count parameter that allows aio to tell the code about its own reference count on the page being migrated. While cleaning up aio_migratepage(), make it validate that the old page being passed in is actually what aio_migratepage() expects to prevent misbehaviour in the case of races.

pstore: Don't allow high traffic options on fragile devices

2013-12-20T21:12:01+00:00

Some pstore backing devices use on board flash as persistent storage. These have limited numbers of write cycles so it is a poor idea to use them from high frequency operations. Signed-off-by: Tony Luck Signed-off-by: Linus Torvalds

mm: do not allocate page->ptl dynamically, if spinlock_t fits to long

2013-12-20T20:25:45+00:00

In struct page we have enough space to fit long-size page->ptl there, but we use dynamically-allocated page->ptl if size(spinlock_t) is larger than sizeof(int). It hurts 64-bit architectures with CONFIG_GENERIC_LOCKBREAK, where sizeof(spinlock_t) == 8, but it easily fits into struct page. Signed-off-by: Kirill A.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to net, ixgbe and e1000e. David provides compiler fixes for e1000e. Don provides a fix for ixgbe to resolve a compile warning. John provides a fix to net where it is useful to be able to walk all upper devices when bringing a device online where the RTNL lock is held. In this case, it is safe to walk the all_adj_list because the RTNL lock is used to protect the write side as well. This patch adds a check to see if the RTNL lock is held before throwing a warning in netdev_all_upper_get_next_dev_rcu(). ==================== Signed-off-by: David S. Miller

mm: numa: guarantee that tlb_flush_pending updates are visible before page table updates

2013-12-19T03:04:51+00:00

According to documentation on barriers, stores issued before a LOCK can complete after the lock implying that it's possible tlb_flush_pending can be visible after a page table update. As per revised documentation, this patch adds a smp_mb__before_spinlock to guarantee the correct ordering. Signed-off-by: Mel Gorman Acked-by: Paul E.
