scsi: advansys: Fix kernel pointer leak

2021-11-26T10:58:42Z

[ Upstream commit d4996c6eac4c81b8872043e9391563f67f13e406 ] Pointers should be printed with %p or %px rather than cast to 'unsigned long' and printed with %lx. Change %lx to %p to print the hashed pointer. Link: https://lore.kernel.org/r/20210929122538.1158235-1-qtxuning1999@sjtu.edu.cn Signed-off-by: Guo Zhi Signed-off-by: Martin K.

scsi: lpfc: Fix list_add() corruption in lpfc_drain_txq()

2021-11-26T10:58:42Z

[ Upstream commit 99154581b05c8fb22607afb7c3d66c1bace6aa5d ] When parsing the txq list in lpfc_drain_txq(), the driver attempts to pass the requests to the adapter. If such an attempt fails, a local "fail_msg" string is set and a log message output. The job is then added to a completions list for cancellation. Processing of any further jobs from the txq list continues, but since "fail_msg" remains set, jobs are added to the completions list regardless of whether a wqe was passed to the adapter. If successfully added to txcmplq, jobs are added to both lists resulting in list corruption. Fix by clearing the fail_msg string after adding a job to the completions list. This stops the subsequent jobs from being added to the completions list unless they had an appropriate failure.

scsi: qla2xxx: Turn off target reset during issue_lip

2021-11-26T10:58:41Z

[ Upstream commit 0b7a9fd934a68ebfc1019811b7bdc1742072ad7b ] When user uses issue_lip to do link bounce, driver sends additional target reset to remote device before resetting the link. The target reset would affect other paths with active I/Os. This patch will remove the unnecessary target reset.

scsi: csiostor: Uninitialized data in csio_ln_vnp_read_cbfn()

2021-11-26T10:58:40Z

[ Upstream commit f4875d509a0a78ad294a1a538d534b5ba94e685a ] This variable is just a temporary variable, used to do an endian conversion. The problem is that the last byte is not initialized. After the conversion is completely done, the last byte is discarded so it doesn't cause a problem. But static checkers and the KMSan runtime checker can detect the uninitialized read and will complain about it.

scsi: core: Put LLD module refcnt after SCSI device is released

2021-11-12T12:17:07Z

commit f2b85040acec9a928b4eb1b57a989324e8e38d3f upstream. SCSI host release is triggered when SCSI device is freed. We have to make sure that the low-level device driver module won't be unloaded before SCSI host instance is released because shost->hostt is required in the release handler. Make sure to put LLD module refcnt after SCSI device is released. Fixes a kernel panic of 'BUG: unable to handle page fault for address' reported by Changhui and Yi.

[ Upstream commit 4e28550829258f7dab97383acaa477bd724c0ff4 ] ISCSI_NET_PARAM_IFACE_ENABLE belongs to enum iscsi_net_param instead of iscsi_iface_param so move it to ISCSI_NET_PARAM.
