2012-02-03rbd: fix safety of rbd_put_client()Alex Elder1-2/+4
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: Alex Elder <elder@dreamhost.com> Signed-off-by: Sage Weil <sage@newdream.net>

2012-02-02drm/radeon/kms/blit: fix blit copy for very large buffersIlija Hadzic1-10/+25
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.

2012-02-01drm/radeon: Set DESKTOP_HEIGHT register to the framebuffer (not mode) height.Michel Dänzer1-2/+2
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 .

2012-01-31IB/mlx4: pass SMP vendor-specific attribute MADs to firmwareJack Morgenstein1-5/+2
In the current code, vendor-specific MADs (e.g with the FDR-10 attribute) are silently dropped by the driver, resulting in timeouts at the sending side and inability to query/configure the relevant feature. However, the ConnectX firmware is able to handle such MADs. For unsupported attributes, the firmware returns a GET_RESPONSE MAD containing an error status. For example, for a FDR-10 node with LID 11: # ibstat mlx4_0 1 CA: 'mlx4_0' Port 1: State: Active Physical state: LinkUp Rate: 40 (FDR10) Base lid: 11 LMC: 0 SM lid: 24 Capability mask: 0x02514868 Port GUID: 0x0002c903002e65d1 Link layer: InfiniBand Extended Port Query (EPI) vendor mad timeouts before the patch: # smpquery MEPI 11 -d ibwarn: [4196] smp_query_via: attr 0xff90 mod 0x0 route Lid 11 ibwarn: [4196] _do_madrpc: retry 1 (timeout 1000 ms) ibwarn: [4196] _do_madrpc: retry 2 (timeout 1000 ms) ibwarn: [4196] _do_madrpc: timeout after 3 retries, 3000 ms ibwarn: [4196] mad_rpc: _do_madrpc failed; dport (Lid 11) smpquery: iberror: [pid 4196] main: failed: operation EPI: ext port info query failed EPI query works OK with the patch: # smpquery MEPI 11 -d ibwarn: [6548] smp_query_via: attr 0xff90 mod 0x0 route Lid 11 ibwarn: [6548] mad_rpc: data offs 64 sz 64 mad data 0000 0000 0000 0001 0000 0001 0000 0001 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 # Ext Port info: Lid 11 port 0 StateChangeEnable:...............0x00 LinkSpeedSupported:..............0x01 LinkSpeedEnabled:................0x01 LinkSpeedActive:.................0x01 Signed-off-by: Jack Morgenstein <jackm@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Acked-by: Ira Weiny <weiny2@llnl.gov> Cc: <stable@vger.kernel.org> Signed-off-by: Roland Dreier <roland@purestorage.com>

1) Setting link attributes can modify the size of the attributes that would be reported on a subsequent getlink netlink operation, therefore min_ifinfo_dump_size needs to be adjusted. From Stefan Gula. 2) Resegmentation of TSO frames while trimming can violate invariants expected by callers, namely that the number of segments can only stay the same or decrease, never increase. If MSS changes, however, we can trim data but then end up with more segments. Fix this by only segmenting to the MSS already recorded in the SKB. That's the simplest fix for now and if we want to get more fancy in the future that's a more involved change. This probably explains some retransmit counter inaccuracies.

2012-01-30Revert "drm/i810: cleanup reclaim_buffers"Daniel Vetter3-13/+11
This reverts commit 87499ffdcb1c70f66988cd8febc4ead0ba2f9118. Where is that paper bag ... ah here. I've failed to take an odd interaction between my other cleanups and this reclaim_buffers patch into account and also failed to properly test it. Looks like there are more dragons and hidden trapdoors in the drm release path than actual lines of code. Until I get a clue, let's just revert this.

2012-01-27RDMA/ucma: Discard all events for new connections until acceptedSean Hefty1-1/+4
After reporting a new connection request to user space, the rdma_ucm will discard subsequent events until the user has associated a user space idenfier with the kernel cm_id. This is needed to avoid reporting a reject/disconnect event to the user for a request that they may not have processed. The user space identifier is set once the user tries to accept the connection request. However, the following race exists in ucma_accept(): ctx->uid = cmd.uid; <events may be reported now> ret = rdma_accept(ctx->cm_id, ...); Once ctx->uid has been set, new events may be reported to the user. While the above mentioned race is avoided, there is an issue that the user _may_ receive a reject/disconnect event if rdma_accept() fails, depending on when the event is processed. To simplify the use of rdma_accept(), discard all events unless rdma_accept() succeeds. This problem was discovered based on questions from Roland Dreier <roland@purestorage.com>.
