Commit 76cde7e4 (PCI / PM: Make PCIe PME interrupts wake up from suspend-to-idle) went too far with preventing pcie_pme_work_fn() from clearing the root port's PME Status and re-enabling the PME interrupt which should be done for PMEs to work correctly after system resume. The failing scenario is as follows: 1. pcie_pme_suspend() finds that the PME IRQ should be designated for system wakeup, so it calls enable_irq_wake() and then sets data->suspend_level to PME_SUSPEND_WAKEUP. 2. PME interrupt happens at this point. 3. pcie_pme_irq() runs, disables the PME interrupt and queues up the execution of pcie_pme_work_fn(). 4. pcie_pme_work_fn() runs before pcie_pme_resume() and breaks out of the loop right away, because data->suspend_level is not PME_SUSPEND_NONE, and it doesn't re-enable the PME interrupt for the same reason. 5. pcie_pme_resume() runs and simply calls disable_irq_wake() without re-enabling the PME interrupt (because data->suspend_level is not PME_SUSPEND_NONE), so the PME interrupt remains disabled and the PME Status remains set. To fix this notice that there is no reason why pcie_pme_work_fn() should behave in a special way during system resume if the PME interrupt is not disabled by pcie_pme_suspend() and partially revert commit 76cde7e4 and restore the previous (and correct) behavior of pcie_pme_work_fn().

Commit dc15e71e (PCI / PM: Restore PME Enable if skipping wakeup setup) introduced a mechanism by which the PME Enable bit can be restored by pci_enable_wake() if dev->wakeup_prepared is set in case it has been overwritten by PCI config space restoration. However, that commit overlooked the fact that on some systems (Dell XPS13 9360 in particular) the AML handling wakeup events checks PME Status and PME Enable and it won't trigger a Notify() for devices where those bits are not set while it is running. That happens during resume from suspend-to-idle when pci_restore_state() invoked by pci_pm_default_resume_early() clears PME Enable before the wakeup events are processed by AML, effectively causing those wakeup events to be ignored. Fix this issue by restoring the PME Enable configuration right after pci_restore_state() has been called instead of doing that in pci_enable_wake().

With a shared policy in place, when one of the CPUs in the policy is hotplugged out and then brought back online, sugov_stop() and sugov_start() are called in order. sugov_stop() removes utilization hooks for each CPU in the policy and does nothing else in the for_each_cpu() loop. sugov_start() on the other hand iterates through the CPUs in the policy and re-initializes the per-cpu structure _and_ adds the utilization hook. This implies that the scheduler is allowed to invoke a CPU's utilization update hook when the rest of the per-cpu structures have yet to be re-inited. Apart from some strange values in tracepoints this doesn't cause a problem, but if we do end up accessing a pointer from the per-cpu sugov_cpu structure somewhere in the sugov_update_shared() path, we will likely see crashes since the memset for another CPU in the policy is free to race with sugov_update_shared from the CPU that is ready to go. So let's fix this now to first init all per-cpu structures, and then add the per-cpu utilization update hooks all at once.

When the minimum performance limit percentage is set to the power-up default, it is possible that minimum performance ratio is off by one. In the set_policy() callback the minimum ratio is calculated by applying global.min_perf_pct to turbo_ratio and rounding up, but the power-up default global.min_perf_pct is already rounded up to the next percent in min_perf_pct_min(). That results in two round up operations, so for the default min_perf_pct one of them is not required. It is better to remove rounding up in min_perf_pct_min() as this matches the displayed min_perf_pct prior to commit c5a2ee7d (cpufreq: intel_pstate: Active mode P-state limits rework) in 4.12. For example on a platform with max turbo ratio of 37 and minimum ratio of 10, the min_perf_pct resulted in 28 with the above commit. Before this commit it was 27 and it will be the same after this change.

Commit ac6424b9 ("sched/wait: Rename wait_queue_t => wait_queue_entry_t") had scripted the renaming incorrectly, and didn't actually check that the 'wait_queue_t' was a full token. As a result, it also triggered on 'wait_queue_token', and renamed that to 'wait_queue_entry_token' entry in the autofs4 packet structure definition too. That was entirely incorrect, and not intended. The end result built fine when building just the kernel - because everything had been renamed consistently there - but caused problems in user space because the "struct autofs_packet_missing" type is exported as part of the uapi. This scripts it all back again: git grep -lw wait_queue_entry_token | xargs sed -i 's/wait_queue_entry_token/wait_queue_token/g' and checks the end result.

Assigning pos for usage early messes up in append mode, where the pos is re-assigned in generic_write_checks(). Assign pos later to get the correct position to write from iocb->ki_pos. Since check_can_nocow also uses the value of pos, we shift generic_write_checks() before check_can_nocow(). Checks with IOCB_DIRECT are present in generic_write_checks(), so checking for IOCB_NOWAIT is enough. Also, put locking sequence in the fast path. This fixes a user visible bug, as reported: "apparently breaks several shell related features on my system. In zsh history stopped working, because no new entries are added anymore.

The AFS_ACE_READ and AFS_ACE_WRITE permission bits should not be used to make access decisions for the directory itself. They are meant to control access for the objects contained in that directory. Reading a directory is allowed if the AFS_ACE_LOOKUP bit is set. This would cause an incorrect access denied error for a directory with AFS_ACE_LOOKUP but not AFS_ACE_READ. The AFS_ACE_WRITE bit does not allow operations that modify the directory. For a directory with AFS_ACE_WRITE but neither AFS_ACE_INSERT nor AFS_ACE_DELETE, this would result in trying operations that would ultimately be denied by the server.

The retry logic for netlink_attachskb() inside sys_mq_notify() is nasty and vulnerable: 1) The sock refcnt is already released when retry is needed 2) The fd is controllable by user-space because we already release the file refcnt so we when retry but the fd has been just closed by user-space during this small window, we end up calling netlink_detachskb() on the error path which releases the sock again, later when the user-space closes this socket a use-after-free could be triggered. Setting 'sock' to NULL here should be sufficient to fix it.

Pull ext4 updates from Ted Ts'o: "The first major feature for ext4 this merge window is the largedir feature, which allows ext4 directories to support over 2 billion directory entries (assuming ~64 byte file names; in practice, users will run into practical performance limits first.) This feature was originally written by the Lustre team, and credit goes to Artem Blagodarenko from Seagate for getting this feature upstream. The second major major feature allows ext4 to support extended attribute values up to 64k. This feature was also originally from Lustre, and has been enhanced by Tahsin Erdogan from Google with a deduplication feature so that if multiple files have the same xattr value (for example, Windows ACL's stored by Samba), only one copy will be stored on disk for encoding and caching efficiency.

This patch adds to support plain user/group quota. Change Note by Jaegeuk Kim. - Use f2fs page cache for quota files in order to consider garbage collection. so, quota files are not tolerable for sudden power-cuts, so user needs to do quotacheck. - setattr() calls dquot_transfer which will transfer inode->i_blocks. We can't reclaim that during f2fs_evict_inode(). So, we need to count node blocks as well in order to match i_blocks with dquot's space. Note that, Chao wrote a patch to count inode->i_blocks without inode block. (f2fs: don't count inode block in in-memory inode.i_blocks) - in f2fs_remount, we need to make RW in prior to dquot_resume. - handle fault_injection case during f2fs_quota_off_umount - TODO: Project quota Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
