ARCH_HAS_NMI_WATCHDOG is a macro defined by arch, but config HARDLOCKUP_DETECTOR depends on it. This is wrong, ARCH_HAS_NMI_WATCHDOG has to be a Kconfig config, and arch's need it should select it explicitly. Signed-off-by:

As described in commit e6fa16ab ("signal: sigprocmask() should do retarget_shared_pending()") the modification of current->blocked is incorrect as we need to check whether the signal we're about to block is pending in the shared queue. Also, use the new helper function introduced in commit 5e6292c0 ("signal: add block_sigmask() for adding sigmask to current->blocked") which centralises the code for updating current->blocked after successfully delivering a signal and reduces the amount of duplicate code across architectures. In the past some architectures got this code wrong, so using this helper function should stop that from happening again. Acked-by:

Pull networking fixes from David Miller: 1) L2TP doesn't get autoloaded when you try to open an L2TP socket due to a missing module alias, fix from Benjamin LaHaise. 2) Netlabel and RDS should propagate gfp flags given to them by callers, fixes from Dan Carpeneter. 3) Recursive locking fix in usbnet wasn't bulletproof and can result in objects going away mid-flight due to races, fix from Ming Lei. 4) Fix up some confusion about a bool module parameter in netfilter's iptable_filter and ip6table_filter, from Rusty Russell. 5) If SKB recycling is used via napi_reuse_skb() we end up with different amounts of headroom reserved than we had at the original SKB allocation. Fix from Eric Dumazet. 6) Fix races in TG3 driver ring refilling, from Michael Chan. 7) We have callbacks for IPSEC replay notifiers, but some call sites were not using the ops method and instead were calling one of the implementations directly. Oops. Fix from Steffen Klassert. 8) Fix IP address validation properly in the bonding driver, the previous fix only works with netlink where the subnet mask and IP address are changed in one atomic operation. When 'ifconfig' ioctls are used the IP address and the subnet mask are changed in two distinct operations. Fix from Andy Gospodarek. 9) Provide a sky2 module operation to work around power management issues with some BIOSes. From Stephen Hemminger. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: usbnet: consider device busy at each recieved packet bonding: remove entries for master_ip and vlan_ip and query devices instead netfilter: remove forward module param confusion. usbnet: don't clear urb->dev in tx_complete usbnet: increase URB reference count before usb_unlink_urb xfrm: Access the replay notify functions via the registered callbacks xfrm: Remove unused xfrm_state from xfrm_state_check_space RDS: use gfp flags from caller in conn_alloc() netlabel: use GFP flags from caller instead of GFP_ATOMIC l2tp: enable automatic module loading for l2tp_ppp cnic: Fix parity error code conflict tg3: Fix RSS ring refill race condition sky2: override for PCI legacy power management net: fix napi_reuse_skb() skb reserve

It's also nice to have some features which support other subsystems building infrastructure on top of regmap. Highlights include: - Support for padding between the register and the value when interacting with the device, sometimes needed for fast interfaces. - Support for applying register updates to the device when restoring the register state. This is intended to be used to apply updates supplied by manufacturers for tuning the performance of the device (many of which are to undocumented registers which aren't otherwise covered). - Support for multi-register operations on cached registers. - Support for syncing only part of the register cache. - Stubs and parameter query functions intended to make it easier for other subsystems to build infrastructure on top of the regmap API. plus a few driver updates making use of the new features which it was easier to merge via this tree." * tag 'regmap-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: (41 commits) regmap: Fix future missing prototype of devres_alloc() and friends regmap: Rejig struct declarations for stubbed API regmap: Fix rbtree block base in sync regcache: Make sure we sync register 0 in an rbtree cache regmap: delete unused module.h from drivers/base/regmap files regmap: Add stub for regcache_sync_region() mfd: Improve performance of later WM1811 revisions regmap: Fix x86_64 breakage regmap: Allow drivers to sync only part of the register cache regmap: Supply ranges to the sync operations regmap: Add tracepoints for cache only and cache bypass regmap: Mark the cache as clean after a successful sync regmap: Remove default cache sync implementation regmap: Skip hardware defaults for LZO caches regmap: Expose the driver name in debugfs mfd: wm8400: Convert to devm_regmap_init_i2c() mfd: wm831x: Convert to devm_regmap_init() mfd: wm8994: Convert to devm_regmap_init() mfd/ASoC: Convert WM8994 driver to use regmap patches mfd: Add __devinit and __devexit annotations in wm8994 ...

It also inhibits cpufreq scaling drivers to load so that only the hypervisor can make power management decisions - fixing a weird perf bug. There is one thing in the Kconfig that you won't like: "default y if (X86_ACPI_CPUFREQ = y || X86_POWERNOW_K8 = y)" (note, that it all depends on CONFIG_XEN which depends on CONFIG_PARAVIRT which by default is off).

The following patch aimed to resolve an issue where secondary, tertiary, etc. addresses added to bond interfaces could overwrite the bond->master_ip and vlan_ip values. commit 917fbdb3 Author: Henrik Saavedra Persson <henrik.e.persson@ericsson.com> Date: Wed Nov 23 23:37:15 2011 +0000 bonding: only use primary address for ARP That patch was good because it prevented bonds using ARP monitoring from sending frames with an invalid source IP address. Unfortunately, it didn't always work as expected. When using an ioctl (like ifconfig does) to set the IP address and netmask, 2 separate ioctls are actually called to set the IP and netmask if the mask chosen doesn't match the standard mask for that class of address. The first ioctl did not have a mask that matched the one in the primary address and would still cause the device address to be overwritten. The second ioctl that was called to set the mask would then detect as secondary and ignored, but the damage was already done. This was not an issue when using an application that used netlink sockets as the setting of IP and netmask came down at once. The inconsistent behavior between those two interfaces was something that needed to be resolved. While I was thinking about how I wanted to resolve this, Ralf Zeidler came with a patch that resolved this on a RHEL kernel by keeping a full shadow of the entries in dev->ifa_list for the bonding device and vlan devices in the bonding driver. I didn't like the duplication of the list as I want to see the 'bonding' struct and code shrink rather than grow, but liked the general idea. As the Subject indicates this patch drops the master_ip and vlan_ip elements from the 'bonding' and 'vlan_entry' structs, respectively. This can be done because a device's address-list is now traversed to determine the optimal source IP address for ARP requests and for checks to see if the bonding device has a particular IP address. This code could have all be contained inside the bonding driver, but it made more sense to me to EXPORT and call inet_confirm_addr since it did exactly what was needed. I tested this and a backported patch and everything works as expected. Ralf also helped with verification of the backported patch. Thanks to Ralf for all his help on this. v2: Whitespace and organizational changes based on suggestions from Jay Vosburgh and Dave Miller. v3: Fixup incorrect usage of rcu_read_unlock based on Dave Miller's suggestion.

It used to be an int, and it got changed to a bool parameter at least 7 years ago. It happens that NF_ACCEPT and NF_DROP are 0 and 1, so this works, but it's unclear, and the check that it's in range is not required. Reported-by:

avc_audit() did a lot of jumping around and had a big stack frame, all for the uncommon case. Split up the uncommon case (which we really can't make go fast anyway) into its own slow function, and mark the conditional branches appropriately for the common likely case. This causes avc_audit() to no longer show up as one of the hottest functions on the branch profiles (the new "perf -b" thing), and makes the cycle profiles look really nice and dense too. The whole audit path is still annoyingly very much one of the biggest costs of name lookup, so these things are worth optimizing for. I wish we could just tell people to turn it off, but realistically we do need it: we just need to make sure that the overhead of the necessary evil is as low as possible. Signed-off-by:

URB unlinking is always racing with its completion and tx_complete may be called before or during running usb_unlink_urb, so tx_complete must not clear urb->dev since it will be used in unlink path, otherwise invalid memory accesses or usb device leak may be caused inside usb_unlink_urb.

Commit 4231d47e(net/usbnet: avoid recursive locking in usbnet_stop()) fixes the recursive locking problem by releasing the skb queue lock, but it makes usb_unlink_urb racing with defer_bh, and the URB to being unlinked may be freed before or during calling usb_unlink_urb, so use-after-free problem may be triggerd inside usb_unlink_urb. The patch fixes the use-after-free problem by increasing URB reference count with skb queue lock held before calling usb_unlink_urb, so the URB won't be freed until return from usb_unlink_urb.

We call the wrong replay notify function when we use ESN replay handling. This leads to the fact that we don't send notifications if we use ESN. Fix this by calling the registered callbacks instead of xfrm_replay_notify(). Signed-off-by:

The xfrm_state argument is unused in this function, so remove it. Also the name xfrm_state_check_space does not really match what this function does. It actually checks if we have enough head and tailroom on the skb. So we rename the function to xfrm_skb_check_space. Signed-off-by:

We should be using the gfp flags the caller specified here, instead of GFP_KERNEL. I think this might be a bugfix, depending on the value of "sock->sk->sk_allocation" when we call rds_conn_create_outgoing() in rds_sendmsg(). Otherwise, it's just a cleanup. Signed-off-by:

This function takes a GFP flags as a parameter, but they are never used. We don't take a lock in this function so there is no reason to prefer GFP_ATOMIC over the caller's GFP flags. There is only one caller, cipso_v4_map_cat_rng_ntoh(), and it passes GFP_ATOMIC as the GFP flags so this doesn't change how the code works. It's just a cleanup. Signed-off-by:

While doing the fs/namei.c cleanups, I ran sparse on it, and it pointed out other large integers and a couple of cases of us using '0' instead of the proper 'NULL'. Sparse still doesn't understand some of the conditional locking going on, but that's no excuse for not fixing up the trivial stuff. Signed-off-by:
