Issue: Request queue count holds the information about free space in request queue which has to be manipulated based on request in and out pointer. But in driver response path, this count was incremented unconditionally, which could move req_in pointer beyond req_out pointer. This scenario leads fw hang during IO. Solution: Request queue count manipulation has to be done in IO path only, keeping req_in and req_out pointer two IOCB count away Signed-off-by:

Problem Description: Disabling pause frames might cause hardware wedging needing a power cycle. This might happen if the Eport is not initialized and is in reset. Solution: Before disabling pause frames ensure that eport is out of reset. Signed-off-by:

For the stpg_endio path we are not evaluating the sense. The bug is that 1. The error value is set to -EIO when there is sense, so we hit the first error check and always return SCSI_DH_IO. 2. h->senselen is set to zero in submit_stpg. It is not later set to req->sense_len like in the synchrounous exection paths, so we must check the req->sense_len field. Signed-off-by:

If a result of the SMP discover function is PHY VACANT, the content of discover response structure (dr) is not valid. It sometimes happens that dr->attached_sas_addr can contain even SAS address of other phy. In such case an invalid phy is created, what causes NULL pointer dereference during destruction of expander's phys. So if a result of SMP function is PHY VACANT, the content of discover response structure (dr) must not be copied to phy structure. This patch fixes the following bug: BUG: unable to handle kernel NULL pointer dereference at 0000000000000030 IP: [<ffffffff811c9002>] sysfs_find_dirent+0x12/0x90 Call Trace: [<ffffffff811c95f5>] sysfs_get_dirent+0x35/0x80 [<ffffffff811cb55e>] sysfs_unmerge_group+0x1e/0xb0 [<ffffffff813329f4>] dpm_sysfs_remove+0x24/0x90 [<ffffffff8132b0f4>] device_del+0x44/0x1d0 [<ffffffffa016fc59>] sas_rphy_delete+0x9/0x20 [scsi_transport_sas] [<ffffffffa01a16f6>] sas_destruct_devices+0xe6/0x110 [libsas] [<ffffffff8107ac7c>] process_one_work+0x16c/0x350 [<ffffffff8107d84a>] worker_thread+0x17a/0x410 [<ffffffff81081b76>] kthread+0x96/0xa0 [<ffffffff81464944>] kernel_thread_helper+0x4/0x10 Signed-off-by:

This patch fixes a reference count bug in the SCSI tape driver which can be reproduced with the following: * Boot with slub_debug=FZPU, tape drive attached * echo 1 > /sys/devices/... tape device pci path .../remove * Wait for device removal * echo 1 > /sys/kernel/slab/blkdev_queue/validate * Slub debug complains about corrupted poison pattern In commit 523e1d39 (block: make gendisk hold a reference to its queue) add_disk() and disk_release() were modified to get/put an additional reference on a disk queue to fix a reference counting discrepency between bdev release and SCSI device removal. The ST driver never calls add_disk(), so this commit introduced an extra kref put when the ST driver frees its struct gendisk. Attempts were made to fix this bug at the block level [1] but later abandoned due to floppy driver issues [2].

Commit 130549fe ("netfilter: reset nf_trace in nf_reset") added code to reset nf_trace in nf_reset(). This is wrong and unnecessary. nf_reset() is used in the following cases: - when passing packets up the the socket layer, at which point we want to release all netfilter references that might keep modules pinned while the packet is queued. nf_trace doesn't matter anymore at this point. - when encapsulating or decapsulating IPsec packets. We want to continue tracing these packets after IPsec processing. - when passing packets through virtual network devices. Only devices on that encapsulate in IPv4/v6 matter since otherwise nf_trace is not used anymore. Its not entirely clear whether those packets should be traced after that, however we've always done that. - when passing packets through virtual network devices that make the packet cross network namespace boundaries. This is the only cases where we clearly want to reset nf_trace and is also what the original patch intended to fix. Add a new function nf_reset_trace() and use it in dev_forward_skb() to fix this properly. Signed-off-by:
