The rbd_client structure uses a kref to arrange for cleaning up and freeing an instance when its last reference is dropped. The cleanup routine is rbd_client_release(), and one of the things it does is delete the rbd_client from rbd_client_list. It acquires node_lock to do so, but the way it is done is still not safe. The problem is that when attempting to reuse an existing rbd_client, the structure found might already be in the process of getting destroyed and cleaned up. Here's the scenario, with "CLIENT" representing an existing rbd_client that's involved in the race: Thread on CPU A | Thread on CPU B --------------- | --------------- rbd_put_client(CLIENT) | rbd_get_client() kref_put() | (acquires node_lock) kref->refcount becomes 0 | __rbd_client_find() returns CLIENT calls rbd_client_release() | kref_get(&CLIENT->kref); | (releases node_lock) (acquires node_lock) | deletes CLIENT from list | ...and starts using CLIENT... (releases node_lock) | and frees CLIENT | <-- but CLIENT gets freed here Fix this by having rbd_put_client() acquire node_lock. The result could still be improved, but at least it avoids this problem. Signed-off-by: NAlex Elder <elder@dreamhost.com> Signed-off-by: NSage Weil <sage@newdream.net>

This fixes the race in process_vm_core found by Oleg (see http://article.gmane.org/gmane.linux.kernel/1235667/ for details). This has been updated since I last sent it as the creation of the new mm_access() function did almost exactly the same thing as parts of the previous version of this patch did. In order to use mm_access() even when /proc isn't enabled, we move it to kernel/fork.c where other related process mm access functions already are.

Lockdep was reporting a possible circular lock dependency in dentry_lease_is_valid(). That function needs to sample the session's s_cap_gen and and s_cap_ttl fields coherently, but needs to do so while holding a dentry lock. The s_cap_lock field was being used to protect the two fields, but that can't be taken while holding a lock on a dentry within the session. In most cases, the s_cap_gen and s_cap_ttl fields only get operated on separately. But in three cases they need to be updated together. Implement a new lock to protect the spots updating both fields atomically is required. Signed-off-by: NAlex Elder <elder@dreamhost.com> Reviewed-by: NSage Weil <sage@newdream.net>

Initializing debufs under monc->mutex introduces a lock dependency for sb->s_type->i_mutex_key, which (combined with several other dependencies) leads to an annoying lockdep warning. There's no particular reason to do the debugfs setup under this lock, so move it out. It used to be the case that our first monmap could come from the OSD; that is no longer the case with recent servers, so we will reliably set up the client entry during the initial authentication. We don't have to worry about racing with debugfs teardown by ceph_debugfs_client_cleanup() because ceph_destroy_client() calls ceph_msgr_flush() first, which will wait for the message dispatch work to complete (and the debugfs init to complete).

Evergreen and NI blit copy was broken if the buffer maps to a rectangle whose one dimension is 16384 (max dimension allowed by these chips). In the mainline kernel, the problem is exposed only when buffers are very large (1G), but it's still a problem. The problem could be exposed for smaller buffers if anyone modifies the algorithm for rectangle construction in r600_blit_create_rect() (the reason why someone would modify that algorithm is to tune the performance of buffer moves). The root cause was in i2f() function which only operated on range between 0 and 16383. Fix this by extending the range of i2f() function to 0 to 32767. While at it improve the function so that the range can be easily extended in the future (if it becomes necessary), cleanup lines over 80 characters, and replace in-line comments with one strategic comment that explains the crux of the function. Credits to michel@daenzer.net for pointing out the root cause of the bug. v2: Fix I2F_MAX_INPUT constant definition goof and warn only once if input argument is out of range. Edit the comment a little bit to avoid some linguistic confusion and make it look better in general.

VIA codecs have several different power-saving features, and one of them is the analog low-current mode. But it turned out that the ALC mode causes pop-noises at each on/off time on some machines. As a quick workaround, disable the ALC when another power-saving feature, the dynamic pin power-control, is turned off, too, since the dynamic power-control is already exposed as a mixer enum element so that user can turn it on/off freely.

Once /proc/pid/mem is opened, the memory can't be released until mem_release() even if its owner exits. Change mem_open() to do atomic_inc(mm_count) + mmput(), this only pins mm_struct. Change mem_rw() to do atomic_inc_not_zero(mm_count) before access_remote_vm(), this verifies that this mm is still alive. I am not sure what should mem_rw() return if atomic_inc_not_zero() fails. With this patch it returns zero to match the "mm == NULL" case, may be it should return -EINVAL like it did before e268337d. Perhaps it makes sense to add the additional fatal_signal_pending() check into the main loop, to ensure we do not hold this memory if the target task was oom-killed.

This patch fixes merge conflict resolution breakage introduced by merge d3712b9d ("Merge tag 'for-linus' of git://github.com/prasad-joshi/logfs_upstream"). The commit changed 'mtd_can_have_bb()' function and made it always return zero, which is incorrect. Instead, we need it to return whether the underlying flash device can have bad eraseblocks or not. UBI needs this information because it affects how it handles the underlying flash. E.g., if the underlying flash is NOR, it cannot have bad blocks and any write or erase error is fatal, and all we can do is to switch to R/O mode. We do not need to reserve a pool of good eraseblocks for bad eraseblocks handling, and so on. This patch also removes 'mtd_can_have_bb()' invocations from Logfs to ensure correct Logfs behavior. I've tested that with this patch UBI works on top of NOR and NAND flashes emulated by mtdram and nandsim correspondingly. This patch is based on patch from Linus Torvalds.

The value of this register is transferred to the V_COUNTER register at the beginning of vertical blank. V_COUNTER is the reference for VLINE waits and goes from VIEWPORT_Y_START to VIEWPORT_Y_START+VIEWPORT_HEIGHT during scanout, so if VIEWPORT_Y_START is not 0, V_COUNTER actually went backwards at the beginning of vertical blank, and VLINE waits excluding the whole scanout area could never finish (possibly only if VIEWPORT_Y_START is larger than the length of vertical blank in scanlines). Setting DESKTOP_HEIGHT to the framebuffer height should prevent this for any kind of VLINE wait. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=45329 .
