As a user of bsg-lib the SAS transport should not poke into request internals but use the bsg_job fields instead. Signed-off-by:

We already support 256 or more segments as long as the architecture supports SG chaining (all the ones that matter do), so removed the weird playing with limits from the job handler. Signed-off-by:

In some environments, user can choose to not enable SCSI-MQ but wants to use FC-NVMe feature of the driver. Since driver relies on Q-Pairs to allocate FC-NVMe resources, use existing module parameter to create Q-Pairs when FC-NVMe is enabled. Signed-off-by:

If we discovered a topology that is N2N then we will issue a login to the target. If our WWPN is bigger than the target's WWPN then we will initiate login, otherwise we will just wait for the target to initiate login. [mkp: many whitespace errors] Signed-off-by:

The MBC_GET_PORT_DATABASE command normally checks the port state information. This patch allows it to save that info in the fcport structure and ignore the check if the query flag is set. [mkp: typo] Signed-off-by:

The ! has higher precedence than the & operation. I've added parenthesis so this works as intended. Fixes: 952c303b ("scsi: lpfc: Ensure io aborts interlocked with the target.") Signed-off-by:

Functions ahc_devlimited_syncrate and ahc_linux_initialize_scsi_bus are declared static in their prototypes but are missing in their definitions, so add the missing static. Cleans up sparse warnings: symbol 'ahc_devlimited_syncrate' was not declared. Should it be static? symbol 'ahc_linux_initialize_scsi_bus' was not declared. Should it be static? Signed-off-by:

gcc-8 points out a logic error that has existed since the start of the git history: drivers/scsi/nsp32.c: In function 'nsp32_selection_autoscsi': drivers/scsi/nsp32.c:607:27: error: bitwise comparison always evaluates to false [-Werror=tautological-compare] if(((phase & BUSMON_BSY) == 1) || (phase & BUSMON_SEL) == 1) { ^~ Presumably the author intended to check if one of two bits was set, so that's what I'm changing the code to. This will obviously change the behavior of the code, hopefully to do the right thing, but I have not tested this or checked if the new "(phase & BUSMON_BSY) || (phase & BUSMON_SEL)" condition should indeed be treated as a fatal error.

We could allocate less memory than intended because we do: bfad->regdata = kzalloc(len << 2, GFP_KERNEL); The shift can overflow leading to a crash. This is debugfs code so the impact is very small. I fixed the network version of this in March with commit 13e2d518 ("bna: integer overflow bug in debugfs"). Fixes: ab2a9ba1 ("[SCSI] bfa: add debugfs support") Signed-off-by:

In case of mgmt cmds, task->hdr is dereferenced after transmitting the pdu in iscsi_tcp_task_xmit(). To handle this case current code increments the Tx skb reference count and frees the skb in cxgbi_cleanup_task(). In some error cases this results in skb leak. To fix this in case of mgmt cmds, allocate a separate buffer for iSCSI hdr and free this buffer in cxgbi_cleanup_task(). Signed-off-by:

scsi: mpt3sas: Fix IO error occurs on pulling out a drive from RAID1 volume created on two SATA drive Whenever an I/O for a RAID volume fails with IOCStatus MPI2_IOCSTATUS_SCSI_IOC_TERMINATED and SCSIStatus equal to (MPI2_SCSI_STATE_TERMINATED | MPI2_SCSI_STATE_NO_SCSI_STATUS) then return the I/O to SCSI midlayer with "DID_RESET" (i.e. retry the IO infinite times) set in the host byte. Previously, the driver was completing the I/O with "DID_SOFT_ERROR" which causes the I/O to be quickly retried. However, firmware needed more time and hence I/Os were failing. Signed-off-by:

For Dev Handles whose value is less than HBA's phys count number, driver would return HBA's SAS address value. As a result, for a Virtual SES device the driver was returning the HBA's SAS address. Updated the driver to return Virtual SES' SAS address. [mkp: clarified commit message] Signed-off-by:

To reduce the memory footprint of the driver in the kdump kernel, we apply the following settings when reset_devices is set: 1. Use single MSI-x vector. 2. Disable RDPQ mode. 3. Set sg_table_size to 32 by default. 4) Set SCSI IO Queue depth to 200. [mkp: fixed commit message] Signed-off-by:

While removing Expander devices, we are removing expander device entry from the list before freeing its child devices. While freeing child device we are finding its parent device node as NULL and therefore we are not freeing the child device's allocated data structures. Updated the driver to remove the expander device from the list only after freeing all its child devices. [mkp: clarified commit message] Signed-off-by:

Earlier Active Cable Exception event with reason code "Cable Degraded (0x02))" was added only for Active Cable. Now this event is extended to Passive cable too. Re-arranged display message accordingly. Also added Cable Exception Event event for SAS3008 & SAS3108 HBAs (i.e. MPI 2.5 spec supporting HBAs). Previously, this event was enabled only for MPI 2.6 spec supporting HBA devices. [mkp: typos] Signed-off-by:
