aoe: reserve enough headroom on skbs

2013-04-05T17:16:53Z

[ Upstream commit 91c5746425aed8f7188a351f1224a26aa232e4b3 ] Some network drivers use a non default hard_header_len Transmitted skb should take into account dev->hard_header_len, or risk crashes or expensive reallocations. In the case of aoe, lets reserve MAX_HEADER bytes. David reported a crash in defxx driver, solved by this patch.

aoe: do not call bdi_init after blk_alloc_queue

2013-01-17T16:43:57Z

commit 0a41409c518083133e79015092585d68915865be upstream, but doesn't apply, so this version is different for older kernels than 3.7.x blk_alloc_queue has already done a bdi_init, so do not bdi_init again in aoeblk_gdalloc. The extra call causes list corruption in the per-CPU backing dev info stats lists. Affected users see console WARNINGs about list_del corruption on percpu_counter_destroy when doing "rmmod aoe" or "aoeflush -a" when AoE targets have been detected and initialized by the system. The patch below applies to v3.6.11, with its v47 aoe driver. It is expected to apply to all currently maintained stable kernels except 3.7.y. A related but different fix has been posted for 3.7.y.

aoe: assert AoE packets marked as requiring no checksum

2012-10-12T20:28:08Z

[ Upstream commit 8babe8cc6570ed896b7b596337eb8fe730c3ff45 ] In order for the network layer to see that AoE requires no checksumming in a generic way, the packets must be marked as requiring no checksum, so we make this requirement explicit with the assertion.

drivers/block/aoe/Makefile: replace the use of -objs with -y

2011-01-19T15:25:02Z

Change Makefile to use -y instead of -objs because -objs is deprecated and should now be switched. According to (documentation/kbuild/makefiles.txt). Signed-off-by: Tracey Dent Cc: "Ed L. Cashin" Signed-off-by: Andrew Morton Signed-off-by: Jens Axboe

block: remove REQ_HARDBARRIER

2010-11-10T13:54:09Z

REQ_HARDBARRIER is dead now, so remove the leftovers. What's left at this point is: - various checks inside the block layer. - sanity checks in bio based drivers. - now unused bio_empty_barrier helper. - Xen blockfront use of BLKIF_OP_WRITE_BARRIER - it's dead for a while, but Xen really needs to sort out it's barrier situaton. - setting of ordered tags in uas - dead code copied from old scsi drivers. - scsi different retry for barriers - it's dead and should have been removed when flushes were converted to FS requests. - blktrace handling of barriers - removed. Someone who knows blktrace better should add support for REQ_FLUSH and REQ_FUA, though. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

aoe: remove dev_base_lock use from aoecmd_cfg_pkts()

2010-11-08T21:50:07Z

dev_base_lock is the legacy way to lock the device list, and is planned to disappear. (writers hold RTNL, readers hold RCU lock) Convert aoecmd_cfg_pkts() to RCU locking. Signed-off-by: Eric Dumazet Cc: "Ed L. Cashin" Signed-off-by: David S. Miller

drivers/block/aoe/aoeblk.c: ratelimit a warning printk

aoe: don't use flush_scheduled_work()
