inotify was supposed to have a dmesg printk ratelimitor which would cause inotify to only emit one message per boot. The static bool was never set so it kept firing messages. This patch correctly limits warnings in multiple places. Signed-off-by: Eric Paris <eparis@redhat.com>

Prior to 2.6.31 inotify would not reuse watch descriptors until all of them had been used at least once. After the rewrite inotify would reuse watch descriptors. The selinux utility 'restorecond' was found to have problems when watch descriptors were reused. This patch reverts to the pre inotify rewrite behavior to not reuse watch descriptors.

fsnotify event initialization is done entry by entry with almost everything set to either 0 or NULL. Use kmem_cache_zalloc and only initialize things that need non-zero initialization. Also means we don't have to change initialization entries based on the config options. Signed-off-by: Eric Paris <eparis@redhat.com>

inotify_free_mark casts directly from an fsnotify_mark_entry to an inotify_inode_mark_entry. This works, but should use container_of instead for future proofing. Signed-off-by: Eric Paris <eparis@redhat.com>

Currently fsnotify defines a static fsnotify event which is sent when a group overflows its allotted queue length. This patch just allocates that event from the event cache rather than defining it statically. There is no known reason that the current implementation is wrong, but this makes sure the event is initialized and created like any other. Signed-off-by: Eric Paris <eparis@redhat.com>

Audit watch init and fsnotify init both use subsys_initcall() but since the audit watch code is linked in before the fsnotify code the audit watch code would be using the fsnotify srcu struct before it was initialized. This patch fixes that problem by moving audit watch init to device_initcall() so it happens after fsnotify is ready.

Audit watch should depend on CONFIG_AUDIT_SYSCALL and should select FSNOTIFY. This splits the spagetti like mixing of audit_watch and audit_filter code so they can be configured seperately. Signed-off-by: Eric Paris <eparis@redhat.com>

This patch allows a task to add a second fsnotify mark to an inode for the same group. This mark will be added to the end of the inode's list and this will never be found by the stand fsnotify_find_mark() function. This is useful if a user wants to add a new mark before removing the old one. Signed-off-by: Eric Paris <eparis@redhat.com>

deleting audit watch rules is not currently done under audit_filter_mutex. It was done this way because we could not hold the mutex during inotify manipulation. Since we are using fsnotify we don't need to do the extra get/put pair nor do we need the private list on which to store the parents while they are about to be freed. Signed-off-by: Eric Paris <eparis@redhat.com>

fsnotify can handle mutexes to be held across all fsnotify operations since it deals strickly in spinlocks. This can simplify and reduce some of the audit_filter_mutex taking and dropping. Signed-off-by: Eric Paris <eparis@redhat.com>

Audit currently uses inotify to pin inodes in core and to detect when watched inodes are deleted or unmounted. This patch uses fsnotify instead of inotify. Signed-off-by: Eric Paris <eparis@redhat.com>

Fix the logic while writing new date/time to the chip. The driver incorrectly wrote back register values to different registers and even with wrong mask. The patch adds clearing of the VLF register, which should be cleared if all date/time values are set.

The command echo "file ec.c +p" >/sys/kernel/debug/dynamic_debug/control causes an oops. Move the call to ddebug_remove_module() down into free_module().

We should use perf_sample_data_init() to initialize struct perf_sample_data. As explained in the description of commit dc1d628a ("perf: Provide generic perf_sample_data initialization"), it is possible for userspace to get the kernel to dereference data.raw, so if it is not initialized, that means that unprivileged userspace can possibly oops the kernel. Using perf_sample_data_init makes sure it gets initialized to NULL. This conversion should have been included in commit dc1d628a, but it got missed.

The PCC cpufreq driver unmaps the mailbox address range if any CPUs fail to initialise, but doesn't do anything to remove the registered CPUs from the cpufreq core resulting in failures further down the line. We're better off simply returning a failure - the cpufreq core will unregister us cleanly if we end up with no successfully registered CPUs. Tidy up the failure path and also add a sanity check to ensure that the firmware gives us a realistic frequency - the core deals badly with that being set to 0.
