* scsi: ufs: ufs-qcom: Fix race conditions caused by ufs_qcom_testbus_config()Can Guo2020-10-291-5/+0
| | | | | | | | | | | | | | | | | | [ Upstream commit 89dd87acd40a44de8ff3358138aedf8f73f4efc6 ] If ufs_qcom_dump_dbg_regs() calls ufs_qcom_testbus_config() from ufshcd_suspend/resume and/or clk gate/ungate context, pm_runtime_get_sync() and ufshcd_hold() will cause a race condition. Fix this by removing the unnecessary calls of pm_runtime_get_sync() and ufshcd_hold().

* scsi: qedi: Fix list_del corruption while removing active I/ONilesh Javali2020-10-291-4/+11
| | | | | | | | | | | | | | | | | | | | [ Upstream commit 28b35d17f9f8573d4646dd8df08917a4076a6b63 ] While aborting the I/O, the firmware cleanup task timed out and driver deleted the I/O from active command list. Some time later the firmware sent the cleanup task response and driver again deleted the I/O from active command list causing firmware to send completion for non-existent I/O and list_del corruption of active command list. Add fix to check if I/O is present before deleting it from the active command list to ensure firmware sends valid I/O completion and protect against list_del corruption.

* scsi: qla2xxx: Warn if done() or free() are called on an already freed srbDaniel Wagner2020-10-292-0/+15
| | | | | | | | | | | | | | | | | | | | | | [ Upstream commit c0014f94218ea3a312f6235febea0d626c5f2154 ] Emit a warning when ->done or ->free are called on an already freed srb. There is a hidden use-after-free bug in the driver which corrupts the srb memory pool which originates from the cleanup callbacks. An extensive search didn't bring any lights on the real problem. The initial fix was to set both pointers to NULL and try to catch invalid accesses. But instead the memory corruption was gone and the driver didn't crash. Since not all calling places check for NULL pointer, add explicitly default handlers. With this we workaround the memory corruption and add a debug help.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In iscsci driver, iscsi_tcp_segment_map() uses the following code to check whether the page should or not be handled by sendpage: if (!recv && page_count(sg_page(sg)) >= 1 && !PageSlab(sg_page(sg))) The "page_count(sg_page(sg)) >= 1 && !PageSlab(sg_page(sg)" part is to make sure the page can be sent to network layer's zero copy path.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When CONFIG_BLK_DEV_ZONED is disabled, allow using host-aware ZBC disks as regular disks. In this case, ensure that command completion is correctly executed by changing sd_zbc_complete() to return good_bytes instead of 0 and causing a hang during device probe (endless retries). When CONFIG_BLK_DEV_ZONED is enabled and a host-aware disk is detected to have partitions, it will be used as a regular disk. In this case, make sure to not do anything in sd_zbc_revalidate_zones() as that triggers warnings. Since all these different cases result in subtle settings of the disk queue zoned model, introduce the block layer helper function blk_queue_set_zoned() to generically implement setting up the effective zoned model according to the disk type, the presence of partitions on the disk and CONFIG_BLK_DEV_ZONED configuration.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initial FLOGIs are failing with the following message: lpfc 0000:13:00.1: 1:(0):0820 FLOGI Failed (x300). BBCredit Not Supported In a prior patch, the READ_SPARAM command was re-ordered to post after CONFIG_LINK as the driver is expected to update the driver's copy of the service parameters for the FLOGI payload. If the bb-credit recovery feature is enabled, this is fine. But on adapters were bb-credit recovery isn't enabled, it would cause the FLOGI to fail. Fix by restoring the original command order (READ_SPARAM before CONFIG_LINK), and after issuing CONFIG_LINK, detect bb-credit recovery support and reissuing READ_SPARAM to obtain the updated service parameters (effectively adding in the fix command order).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It was discovered that sdparm will fail when attempting to disable write cache on a SATA disk connected via libsas. In the ATA command set the write cache state is controlled through the SET FEATURES operation. This is roughly corresponds to MODE SELECT in SCSI and the latter command is what is used in the SCSI-ATA translation layer. A subtle difference is that a MODE SELECT carries data whereas SET FEATURES is defined as a non-data command in ATA. Set the DMA data direction to DMA_NONE if the requested ATA command is identified as non-data.

During pt2pt login, the driver completes its FLOGI request with the remote device having WWN precedence. The remote device issues its own (delayed) FLOGI after accepting the driver's and, upon transmitting the FLOGI, immediately recognizes it has already processed the driver's FLOGI thus it transitions to sending a PLOGI before waiting for an ACC to its FLOGI. In the driver, the FLOGI is received and an ACC sent, followed by the PLOGI being received and an ACC sent. The issue is that the PLOGI reception occurs before the response from the adapter from the FLOGI ACC is received. Processing of the PLOGI sets state flags to perform the REG_RPI mailbox command and proceed with the rest of discovery on the port. The same completion routine used by both FLOGI and PLOGI is generic in nature. One of the things it does is clear flags, and those flags happen to drive the rest of discovery. So what happened was the PLOGI processing set the flags, the FLOGI ACC completion cleared them, thus when the PLOGI ACC completes it doesn't see the flags and stops. Fix by modifying the generic completion routine to not clear the rest of discovery flag (NLP_ACC_REGLOGIN) unless the completion is also associated with performing a mailbox command as part of its handling. For things such as FLOGI ACC, there isn't a subsequent action to perform with the adapter, thus there is no mailbox cmd ptr. PLOGI ACC though will perform REG_RPI upon completion, thus there is a mailbox cmd ptr.
