write_lock(¤t->fs->lock) guarantees we can't wrongly miss LSM_UNSAFE_SHARE, this is what we care about. Use rcu_read_lock() instead of ->siglock to iterate over the sub-threads. We must see all CLONE_THREAD|CLONE_FS threads which didn't pass exit_fs(), it takes fs->lock too. With or without this patch we can miss the freshly cloned thread and set LSM_UNSAFE_SHARE, we don't care.

由 Oleg Nesterov 提交于
If do_execve() fails after check_unsafe_exec(), it clears fs->in_exec unconditionally. This is wrong if we race with our sub-thread which also does do_execve: Two threads T1 and T2 and another process P, all share the same ->fs. T1 starts do_execve(BAD_FILE). It calls check_unsafe_exec(), since ->fs is shared, we set LSM_UNSAFE but not ->in_exec. P exits and decrements fs->users. T2 starts do_execve(), calls check_unsafe_exec(), now ->fs is not shared, we set fs->in_exec. T1 continues, open_exec(BAD_FILE) fails, we clear ->in_exec and return to the user-space. T1 does clone(CLONE_FS /* without CLONE_THREAD */). T2 continues without LSM_UNSAFE_SHARE while ->fs is shared with another process. Change check_unsafe_exec() to return res = 1 if we set ->in_exec, and change do_execve() to clear ->in_exec depending on res. When do_execve() suceeds, it is safe to clear ->in_exec unconditionally. It can be set only if we don't share ->fs with another process, and since we already killed all sub-threads either ->in_exec == 0 or we are the only user of this ->fs. Also, we do not need fs->lock to clear fs->in_exec.

Currently we look it up from ->ioprio, but ->ioprio can change if either the process gets its IO priority changed explicitly, or if cfq decides to temporarily boost it. So if we are unlucky, we can end up attempting to remove a node from a different rbtree root than where it was added. Fix this by using ->org_ioprio as the prio_tree index, since that will only change for explicit IO priority settings (not for a boost). Additionally cache the rbtree root inside the cfqq, then we don't have to add code to reinsert the cfqq in the prio_tree if IO priority changes. Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

cfq_prio_tree_lookup() should return the direct match, yet it always returns zero. Fix that. cfq_prio_tree_add() assumes that we don't get a direct match, while it is very possible that we do. Using O_DIRECT, you can have different cfqq with matching requests, since you don't have the page cache to serialize things for you. Fix this bug by only adding the cfqq if there isn't an existing match. Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

Very rarely under stress testing of dm, oopses are occuring as something tampers with an old stack frame. This has been traced back to blk_abort_queue() leaving a timeout_list pointing to the stack. The reason is that sometimes blk_abort_request() won't delete the timer (if the request is marked as complete but before the timer has been removed, a small race window). Fix this by splicing back from the ususally empty list to the q->timeout_list. Signed-off-by: NHannes Reinecke <hare@suse.de> Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

The umem driver issues two warnings on boot, due to blk_plug_device() and blk_remove_plug() being called without q->queue_lock held. Starting with e48ec690 (block: extend queue_flag bitops), the queue_flag_* functions warn if q->queue_lock doesn't appear to be locked. In fact, q->queue_lock is NULL (though that apparently isn't otherwise a problem as the driver is using card->lock for everything). Although blk_init_queue() with take a request_fn_proc and spinlock_t*, there isn't a corresponding init helper that takes a make_request_fn. Setting queue_lock to &card->lock explicitly seems to work fine for me. The warning goes away and the device appears to behave.

This simplifies I/O stat accounting switching code and separates it completely from I/O scheduler switch code. Requests are accounted according to the state of their request queue at the time of the request allocation. There is no need anymore to flush the request queue when switching I/O accounting state.

Bugfixes noted by checking the code against the controller documentation (TI document number SPRUE21): - Remove declarations for eight non-existent registers (!); and remove accesses to two of them. - Remove access to various non-existent bitfields in some of the registers which *do* exist (those fields must-be-zero). - Provide comment to replace bogus reset logic (removed above, it relied on non-existent bitfields). Resets require GPIO help; this driver doesn't currently know about that. With some minor cleanup: relocate a comment, avoid an extra lookup of the PIO timings.

Always omit frame pointers on s390. They aren't too useful for the kernel since we have already the kernel stack backchain which allows us to walk the kernel stack. So eleminate the extra code for frame pointers. Only allow the extra code for the function tracer since the gcc compile options -pg and -fomit-frame-pointer are incompatible.

The cpu idle field in the output of /proc/stat is too small for cpus that have been idle for more than a tick. Add the architecture hook arch_idle_time that allows to add the not accounted idle time of a sleeping cpu without waking the cpu. The s390 implementation of arch_idle_time uses the already existing s390_idle_data per_cpu variable to find the sleep time of a neighboring idle cpu.

The appldata_ops callbacks are called with a spin_lock held. But the appldata_mem callback then calls all_vm_events(), which calls get_online_cpus(), which might sleep. This possible deadlock is fixed by using a mutex instead of a spin_lock. Signed-off-by: NGerald Schaefer <gerald.schaefer@de.ibm.com> Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

GFS2 has a goal block associated with each inode indicating the search start position for future block allocations (in fact there are two, but thats for backward compatibility with GFS1 as they are set to identical locations in GFS2). In some circumstances, depending on the ordering of updates to the inode it was possible for the goal block settings to not be updated on disk. This patch ensures that the goal block will always get updated, thus reducing the potential for searching the same (already allocated) blocks again when looking for free space during block allocation.
