Pull networking updates from David Miller: "Much more accumulated than I would have liked due to an unexpected bout with a nasty flu: 1) AH and ESP input don't set ECN field correctly because the transport head of the SKB isn't set correctly, fix from Li RongQing. 2) If netfilter conntrack zones are disabled, we can return an uninitialized variable instead of the proper error code.

2013-01-27mfd: da9052/53 lockup fixAshish Jangam
An issue has been reported where the PMIC either locks up or fails to respond following a system Reset. This could result in a second write in which the bus writes the current content of the write buffer to address of the last I2C access. The failure case is where this unwanted write transfers incorrect data to a critical register. This patch fixes this issue to by following any read or write with a dummy read to a safe register address. A safe register address is one where the contents will not affect the operation of the system.

2013-01-22ptrace: introduce signal_wake_up_state() and ptrace_signal_wake_up()Oleg Nesterov
Cleanup and preparation for the next change. signal_wake_up(resume => true) is overused. None of ptrace/jctl callers actually want to wakeup a TASK_WAKEKILL task, but they can't specify the necessary mask. Turn signal_wake_up() into signal_wake_up_state(state), reintroduce signal_wake_up() as a trivial helper, and add ptrace_signal_wake_up() which adds __TASK_TRACED. This way ptrace_signal_wake_up() can work "inside" ptrace_request() even if the tracee doesn't have the TASK_WAKEKILL bit set.

2013-01-16module, async: async_synchronize_full() on module init iff async is usedTejun Heo
If the default iosched is built as module, the kernel may deadlock while trying to load the iosched module on device probe if the probing was running off async. This is because async_synchronize_full() at the end of module init ends up waiting for the async job which initiated the module loading. async A modprobe 1. finds a device 2. registers the block device 3. request_module(default iosched) 4. modprobe in userland 5. load and init module 6. async_synchronize_full() Async A waits for modprobe to finish in request_module() and modprobe waits for async A to finish in async_synchronize_full(). Because there's no easy to track dependency once control goes out to userland, implementing properly nested flushing is difficult. For now, make module init perform async_synchronize_full() iff module init has queued async jobs as suggested by Linus. This avoids the described deadlock because iosched module doesn't use async and thus wouldn't invoke async_synchronize_full(). This is hacky and incomplete. It will deadlock if async module loading nests; however, this works around the known problem case and seems to be the best of bad options.

2013-01-15cpuidle: remove the power_specified field in the driverDaniel Lezcano
We realized that the power usage field is never filled and when it is filled for tegra, the power_specified flag is not set causing all of these values to be reset when the driver is initialized with set_power_state(). However, the power_specified flag can be simply removed under the assumption that the states are always backward sorted, which is the case with the current code. This change allows the menu governor select function and the cpuidle_play_dead() to be simplified. Moreover, the set_power_states() function can removed as it does not make sense any more. Drop the power_specified flag from struct cpuidle_driver and make the related changes as described above. As a consequence, this also fixes the bug where on the dynamic C-states system, the power fields are not initialized.

2013-01-14tun: fix LSM/SELinux labeling of tun/tap devicesPaul Moore
This patch corrects some problems with LSM/SELinux that were introduced with the multiqueue patchset. The problem stems from the fact that the multiqueue work changed the relationship between the tun device and its associated socket; before the socket persisted for the life of the device, however after the multiqueue changes the socket only persisted for the life of the userspace connection (fd open). For non-persistent devices this is not an issue, but for persistent devices this can cause the tun device to lose its SELinux label. We correct this problem by adding an opaque LSM security blob to the tun device struct which allows us to have the LSM security state, e.g. SELinux labeling information, persist for the lifetime of the tun device. In the process we tweak the LSM hooks to work with this new approach to TUN device/socket labeling and introduce a new LSM hook, security_tun_dev_attach_queue(), to approve requests to attach to a TUN queue via TUNSETQUEUE. The SELinux code has been adjusted to match the new LSM hooks, the other LSMs do not make use of the LSM TUN controls. This patch makes use of the recently added "tun_socket:attach_queue" permission to restrict access to the TUNSETQUEUE operation. On older SELinux policies which do not define the "tun_socket:attach_queue" permission the access control decision for TUNSETQUEUE will be handled according to the SELinux policy's unknown permission setting.

2013-01-14[libata] replace sata_settings with devslp_timingShane Huang
NCQ capability was used to check availability of SATA Settings page from Identify Device Data Log, which contains DevSlp timing variables. It does not work on some HDDs and leads to error messages. IDENTIFY word 78 bit 5(Hardware Feature Control) can't work either because it is only the sufficient condition of Identify Device data log, not the necessary condition. This patch replaced ata_device->sata_settings with ->devslp_timing to only save DevSlp timing variables(8 bytes), instead of the whole SATA Settings page(512 bytes).

2013-01-12netfilter: nf_conntrack: fix BUG_ON while removing nf_conntrack with netnsPablo Neira Ayuso
canqun zhang reported that we're hitting BUG_ON in the nf_conntrack_destroy path when calling kfree_skb while rmmod'ing the nf_conntrack module. Currently, the nf_ct_destroy hook is being set to NULL in the destroy path of conntrack.init_net. However, this is a problem since init_net may be destroyed before any other existing netns (we cannot assume any specific ordering while releasing existing netns according to what I read in recent emails).

After alloc_netdev*() call, some cfg80211 drivers provide they own ethtool_ops, but some do not. For them, wireless core provide generic cfg80211_ethtool_ops, which is assigned in NETDEV_REGISTER notify call: if (!dev->ethtool_ops) dev->ethtool_ops = &cfg80211_ethtool_ops; But after Eric's commit, dev->ethtool_ops is no longer NULL (on cfg80211 drivers without custom ethtool_ops), but points to &default_ethtool_ops.

2013-01-11lib/rbtree.c: avoid the use of non-static __always_inlineMichel Lespinasse
lib/rbtree.c declared __rb_erase_color() as __always_inline void, and then exported it with EXPORT_SYMBOL. This was because __rb_erase_color() must be exported for augmented rbtree users, but it must also be inlined into rb_erase() so that the dummy callback can get optimized out of that call site. (Actually with a modern compiler, none of the dummy callback functions should even be generated as separate text functions). The above usage is legal C, but it was unusual enough for some compilers to warn about it. This change makes things more explicit, with a static __always_inline ____rb_erase_color function for use in rb_erase(), and a separate non-inline __rb_erase_color function for use in rb_erase_augmented call sites.

2013-01-11mm: compaction: partially revert capture of suitable high-order pageMel Gorman
Eric Wong reported on 3.7 and 3.8-rc2 that ppoll() got stuck when waiting for POLLIN on a local TCP socket. It was easier to trigger if there was disk IO and dirty pages at the same time and he bisected it to commit 1fb3f8ca0e92 ("mm: compaction: capture a suitable high-order page immediately when it is made available"). The intention of that patch was to improve high-order allocations under memory pressure after changes made to reclaim in 3.6 drastically hurt THP allocations but the approach was flawed. For Eric, the problem was that page->pfmemalloc was not being cleared for captured pages leading to a poor interaction with swap-over-NFS support causing the packets to be dropped. However, I identified a few more problems with the patch including the fact that it can increase contention on zone->lock in some cases which could result in async direct compaction being aborted early. In retrospect the capture patch took the wrong approach. What it should have done is mark the pageblock being migrated as MIGRATE_ISOLATE if it was allocating for THP and avoided races that way. While the patch was showing to improve allocation success rates at the time, the benefit is marginal given the relative complexity and it should be revisited from scratch in the context of the other reclaim-related changes that have taken place since the patch was first written and tested. This patch partially reverts commit 1fb3f8ca0e92 ("mm: compaction: capture a suitable high-order page immediately when it is made available").

This avoids issues where people want the audit defines and userland ptrace api. Including both the kernel ptrace and the userland ptrace headers can easily lead to failure.

2013-01-11audit: create explicit AUDIT_SECCOMP event typeKees Cook
The seccomp path was using AUDIT_ANOM_ABEND from when seccomp mode 1 could only kill a process. While we still want to make sure an audit record is forced on a kill, this should use a separate record type since seccomp mode 2 introduces other behaviors. In the case of "handled" behaviors (process wasn't killed), only emit a record if the process is under inspection. This change also fixes userspace examination of seccomp audit events, since it was considered malformed due to missing fields of the AUDIT_ANOM_ABEND event type.

In some cases, free_irq_cpu_rmap() is called while holding a lock (eg rtnl). This can lead to deadlocks, because it invokes flush_scheduled_work() which ends up waiting for whole system workqueue to flush, but some pending works might try to acquire the lock we are already holding. This commit uses reference-counting to replace irq_run_affinity_notifiers(). It also removes irq_run_affinity_notifiers() altogether.
