The SET_PORT functions are implemented in port.c, which is part of mlx4_core, these functions are exported. The functions are in use by the mlx4_en module (were originally part of mlx4_en). Their declaration remained in mlx4_en module, moving the declaration to the right location. Signed-off-by:

The keys used for the hardware RSS topelitz hash are of type __be32 where the values provided by the driver are from array of u32, this triggered sparse warning on incorrect type in assignment as of different base types. Since these values are picked randomly, the fix is to transform the key to __be32 by executing cpu_to_be_32() Signed-off-by:

Localized the pdev->dev, and using dma_map instead of pci_map There are multiple map/unmap operations on data path, optimizing those by saving redundant pointer access. Those places were identified as hot-spots when running kernel profiling during some benchmarks. The fixes had most impact when testing packet rate with small packets, reducing several % from CPU load, and in some case being the difference between reaching wire speed or being CPU bound.

Dave Jones reports a few Fedora users hitting the BUG_ON(mm->nr_ptes...) in exit_mmap() recently. Quoting Hugh's discovery and explanation of the SMP race condition: "mm->nr_ptes had unusual locking: down_read mmap_sem plus page_table_lock when incrementing, down_write mmap_sem (or mm_users 0) when decrementing; whereas THP is careful to increment and decrement it under page_table_lock. Now most of those paths in THP also hold mmap_sem for read or write (with appropriate checks on mm_users), but two do not: when split_huge_page() is called by hwpoison_user_mappings(), and when called by add_to_swap(). It's conceivable that the latter case is responsible for the exit_mmap() BUG_ON mm->nr_ptes that has been reported on Fedora." The simplest way to fix it without having to alter the locking is to make split_huge_page() a noop in nr_ptes terms, so by counting the preallocated pagetables that exists for every mapped hugepage. It was an arbitrary choice not to count them and either way is not wrong or right, because they are not used but they're still allocated. Reported-by:

Hugh Dickins authored
When moving tasks from old memcg (with move_charge_at_immigrate on new memcg), followed by removal of old memcg, hit General Protection Fault in mem_cgroup_lru_del_list() (called from release_pages called from free_pages_and_swap_cache from tlb_flush_mmu from tlb_finish_mmu from exit_mmap from mmput from exit_mm from do_exit). Somewhat reproducible, takes a few hours: the old struct mem_cgroup has been freed and poisoned by SLAB_DEBUG, but mem_cgroup_lru_del_list() is still trying to update its stats, and take page off lru before freeing. A task, or a charge, or a page on lru: each secures a memcg against removal. In this case, the last task has been moved out of the old memcg, and it is exiting: anonymous pages are uncharged one by one from the memcg, as they are zapped from its pagetables, so the charge gets down to 0; but the pages themselves are queued in an mmu_gather for freeing. Most of those pages will be on lru (and force_empty is careful to lru_add_drain_all, to add pages from pagevec to lru first), but not necessarily all: perhaps some have been isolated for page reclaim, perhaps some isolated for other reasons. So, force_empty may find no task, no charge and no page on lru, and let the removal proceed. There would still be no problem if these pages were immediately freed; but typically (and the put_page_testzero protocol demands it) they have to be added back to lru before they are found freeable, then removed from lru and freed. We don't see the issue when adding, because the mem_cgroup_iter() loops keep their own reference to the memcg being scanned; but when it comes to mem_cgroup_lru_del_list(). I believe this was not an issue in v3.2: there, PageCgroupAcctLRU and PageCgroupUsed flags were used (like a trick with mirrors) to deflect view of pc->mem_cgroup to the stable root_mem_cgroup when neither set. 38c5d72f ("memcg: simplify LRU handling by new rule") mercifully removed those convolutions, but left this General Protection Fault. But it's surprisingly easy to restore the old behaviour: just check PageCgroupUsed in mem_cgroup_lru_add_list() (which decides on which lruvec to add), and reset pc to root_mem_cgroup if page is uncharged. A risky change? just going back to how it worked before; testing, and an audit of uses of pc->mem_cgroup, show no problem. And there's a nice bonus: with mem_cgroup_lru_add_list() itself making sure that an uncharged page goes to root lru, mem_cgroup_reset_owner() no longer has any purpose, and we can safely revert 4e5f01c2 ("memcg: clear pc->mem_cgroup if necessary"). Calling update_page_reclaim_stat() after add_page_to_lru_list() in swap.c is not strictly necessary: the lru_lock there, with RCU before memcg structures are freed, makes mem_cgroup_get_reclaim_stat_from_page safe without that; but it seems cleaner to rely on one dependency less.

debugobjects is now printing a warning when a fixup for a NOTAVAILABLE object is run. This causes the selftest to fail like: ODEBUG: selftest warnings failed 4 != 5 We could just increase the number of warnings that the selftest is expecting to see because that is actually what has changed. But, it turns out that fixup_activate() was written with inverted logic and thus a fixup for a static object returned 1 indicating the object had been fixed, and 0 otherwise. Fix the logic to be correct and update the counts to reflect that nothing needed fixing for a static object. Signed-off-by:

We have forgotten the rules of lock nesting: the irq-safe ones must be taken inside the non-irq-safe ones, otherwise we are open to deadlock: CPU0 CPU1 ---- ---- lock(&(&pc->lock)->rlock); local_irq_disable(); lock(&(&zone->lru_lock)->rlock); lock(&(&pc->lock)->rlock); <Interrupt> lock(&(&zone->lru_lock)->rlock); To check a different locking issue, I happened to add a spin_lock to memcg's bit_spin_lock in lock_page_cgroup(), and lockdep very quickly complained about __mem_cgroup_commit_charge_lrucare() (on CPU1 above). So delete __mem_cgroup_commit_charge_lrucare(), passing a bool lrucare to __mem_cgroup_commit_charge() instead, taking zone->lru_lock under lock_page_cgroup() in the lrucare case. The original was using spin_lock_irqsave, but we'd be in more trouble if it were ever called at interrupt time: unconditional _irq is enough. And ClearPageLRU before del from lru, SetPageLRU before add to lru: no strong reason, but that is the ordering used consistently elsewhere.

check_hung_uninterruptible_tasks()->rcu_lock_break() introduced by "softlockup: check all tasks in hung_task" commit ce9dbe24 looks absolutely wrong. - rcu_lock_break() does put_task_struct(). If the task has exited it is not safe to even read its ->state, nothing protects this task_struct. - The TASK_DEAD checks are wrong too. Contrary to the comment, we can't use it to check if the task was unhashed. It can be unhashed without TASK_DEAD, or it can be valid with TASK_DEAD. For example, an autoreaping task can do release_task(current) long before it sets TASK_DEAD in do_exit(). Or, a zombie task can have ->state == TASK_DEAD but release_task() was not called, and in this case we must not break the loop. Change this code to check pid_alive() instead, and do this before we drop the reference to the task_struct. Note: while_each_thread() under rcu_read_lock() is not really safe, it can livelock. This will be fixed later, but fortunately in this case the "max_count" logic saves us anyway. Signed-off-by:

Make vfork() killable. Change do_fork(CLONE_VFORK) to do wait_for_completion_killable(). If it fails we do not return to the user-mode and never touch the memory shared with our child. However, in this case we should clear child->vfork_done before return, we use task_lock() in do_fork()->wait_for_vfork_done() and complete_vfork_done() to serialize with each other. Note: now that we use task_lock() we don't really need completion, we could turn task->vfork_done into "task_struct *wake_up_me" but this needs some complications. NOTE: this and the next patches do not affect in-kernel users of CLONE_VFORK, kernel threads run with all signals ignored including SIGKILL/SIGSTOP. However this is obviously the user-visible change. Not only a fatal signal can kill the vforking parent, a sub-thread can do execve or exit_group() and kill the thread sleeping in vfork(). Signed-off-by:

It will opportunistically allocate kiocbs, and then trim back the list of iocbs when there is not enough room in the completion ring to hold all of the events. In the case above, what happens is that the pruning back of events ends up freeing up the last active request and the context is marked as dead, so it is thus responsible for waking up waiters. Unfortunately, the code does not check for this condition, so we end up with a hung task. Signed-off-by:Jeff Moyer <jmoyer@redhat.com> Reported-by:

Since commit 04c6862c ("kmsg_dump: add kmsg_dump() calls to the reboot, halt, poweroff and emergency_restart paths"), kmsg_dump() gets run on normal paths including poweroff and reboot. This is less than ideal given pstore implementations that can only represent single backtraces, since a reboot may overwrite a stored oops before it's been picked up by userspace. In addition, some pstore backends may have low performance and provide a significant delay in reboot as a result. This patch adds a printk.always_kmsg_dump kernel parameter (which can also be changed from userspace). Without it, the code will only be run on failure paths rather than on normal paths. The option can be enabled in environments where there's a desire to attempt to audit whether or not a reboot was cleanly requested or not. Signed-off-by:

Production GMA3600/3650 hardware turns out to be subtly different to the development platforms. This combined with a minor driver bug is causing the kernel to hang on these platforms. This patch does the following - turn down a couple of messages that were meant to be debug and are causing much confusion - ensure the hotplug interrupt is disabled on Cedartrail systems. - fix a bug where gtt roll mode called psbfb_sync, which tries to sync the 2D engine. On other devices it is harmless as the 2D engine is present but not in use when in gtt roll mode, on Cedartrail it causes a hang Without these changes 3.3-rc hangs on boot on Cedartrail based systems.

Pull per-cpu patches from Tejun Heo: "This pull request contains four patches. One replaces manual clearing with bitmap_clear(), two fix generic definition of __this_cpu ops so that they don't choose unnecessarily strict arch version. One makes _this_cpu definition use raw_local_irq_*() so that it doesn't end up wrecking irq on/off state tracking when used from inside lockdep. Of the four patches, the raw_local_irq_*() update is the most important, so please feel free to cherry pick only that one patch and ignore the rest if you want to - commit e920d597 'percpu: use raw_local_irq_* in _this_cpu op'." * 'for-3.3-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu: percpu: fix __this_cpu_{sub,inc,dec}_return() definition percpu: use raw_local_irq_* in _this_cpu op percpu: fix generic definition of __this_cpu_add_and_return() percpu: use bitmap_clear
