      write_lock(&current->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.

      do_execve() must not clear fs->in_exec if it was set by another thread · 8c652f96
      Oleg Nesterov 提交于
      If do_execve() fails after check_unsafe_exec(), it clears fs->in_exec

      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.

      cfq-iosched: cache prio_tree root in cfqq->p_root · f2d1f0ae
      Jens Axboe 提交于
      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.

      cfq-iosched: fix bug with aliased request and cooperation detection · 3ac6c9f8
      Jens Axboe 提交于
      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.

      block: fix intermittent dm timeout based oops · 17d5c8ca
      Hannes Reinecke 提交于
      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.

      umem: fix request_queue lock warning · f3c737de
      Sage Weil 提交于
      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.
