Commit 3ce41966 ("scsi: iscsi: Register sysfs for iscsi workqueue") enabled 'cpumask' support for iSCSI workqueues. However, it is unnecessary to set max_active = 2 since 'cpumask' can still be modified when max_active is 1. This patch sets max_active to 1 so as to keep the same behaviour as before.

The mpt fusion driver still uses the legacy PCI DMA API which hardcodes atomic allocations. This caused the driver to fail to load on some powerpc VMs with incoherent DMA and small memory sizes. Switch to use the modern DMA API and sleeping allocations for large allocations instead. This is not a full cleanup of the PCI DMA API usage yet, but just enough to fix the regression caused by reducing the default atomic pool size.

The sense data buffer in sense_buf_pool is allocated with size of MPT_SENSE_BUFFER_ALLOC(64) (multiplied by req_depth) while SNS_LEN(sc)(96) is used when reading the data. That may lead to a read from unallocated area, sometimes from another (unallocated) page. To fix this, limit the read size to MPT_SENSE_BUFFER_ALLOC.

Suppose that, for unrelated reasons, FSF requests on behalf of recovery are very slow and can run into the ERP timeout. In the case at hand, we did adapter recovery to a large degree. However due to the slowness a LUN open is pending so the corresponding fc_rport remains blocked. After fast_io_fail_tmo we trigger close physical port recovery for the port under which the LUN should have been opened. The new higher order port recovery dismisses the pending LUN open ERP action and dismisses the pending LUN open FSF request. Such dismissal decouples the ERP action from the pending corresponding FSF request by setting zfcp_fsf_req->erp_action to NULL (among other things) [zfcp_erp_strategy_check_fsfreq()]. If now the ERP timeout for the pending open LUN request runs out, we must not use zfcp_fsf_req->erp_action in the ERP timeout handler. This is a problem since v4.15 commit 75492a51 ("s390/scsi: Convert timers to use timer_setup()"). Before that we intentionally only passed zfcp_erp_action as context argument to zfcp_erp_timeout_handler(). Note: The lifetime of the corresponding zfcp_fsf_req object continues until a (late) response or an (unrelated) adapter recovery. Just like the regular response path ignores dismissed requests [zfcp_fsf_req_complete() => zfcp_fsf_protstatus_eval() => return early] the ERP timeout handler now needs to ignore dismissed requests. So simply return early in the ERP timeout handler if the FSF request is marked as dismissed in its status flags. To protect against the race where zfcp_erp_strategy_check_fsfreq() dismisses and sets zfcp_fsf_req->erp_action to NULL after our previous status flag check, return early if zfcp_fsf_req->erp_action is NULL. After all, the former ERP action does not need to be woken up as that was already done as part of the dismissal above [zfcp_erp_action_dismiss()]. This fixes the following panic due to kernel page fault in IRQ context: Unable to handle kernel pointer dereference in virtual kernel address space Failing address: 0000000000000000 TEID: 0000000000000483 Fault in home space mode while using kernel ASCE.

The driver performs SCR (state change registration) in all modes including pure target mode. For each RSCN, scan_needed flag is set in qla2x00_handle_rscn() for the port mentioned in the RSCN and fabric rescan is scheduled. During the rescan, GNN_FT handler, qla24xx_async_gnnft_done() deletes session of the port that caused the RSCN. In target mode, the session deletion has an impact on ATIO handler, qlt_24xx_atio_pkt(). Target responds with SAM STATUS BUSY to I/O incoming from the deleted session. qlt_handle_cmd_for_atio() and qlt_handle_task_mgmt() return -EFAULT if they are not able to find session of the command/TMF, and that results in invocation of qlt_send_busy(): qlt_24xx_atio_pkt_all_vps: qla_target(0): type 6 ox_id 0014 qla_target(0): Unable to send command to target, sending BUSY status Such response causes command timeout on the initiator. Error handler thread on the initiator will be spawned to abort the commands: scsi 23:0:0:0: tag#0 abort scheduled scsi 23:0:0:0: tag#0 aborting command qla2xxx [0000:af:00.0]-188c:23: Entered qla24xx_abort_command. qla2xxx [0000:af:00.0]-801c:23: Abort command issued nexus=23:0:0 -- 0 2003. Command abort is rejected by target and fails (2003), error handler then tries to perform DEVICE RESET and TARGET RESET but they're also doomed to fail because TMFs are ignored for the deleted sessions. Then initiator makes BUS RESET that resets the link via qla2x00_full_login_lip(). BUS RESET succeeds and brings initiator port up, SAN switch detects that and sends RSCN to the target port and it fails again the same way as described above. It never goes out of the loop. The change breaks the RSCN loop by keeping initiator sessions mentioned in RSCN payload in all modes, including dual and pure target mode.

The qla2xxx driver knows when request was processed successfully or not. But it always sets the NVMe status code to 0/NVME_SC_SUCCESS. The upper layer needs to figure out from the rcv_rsplen and transferred_length variables if the request was transferred successfully. This is not always possible, e.g. when the request data length is 0, the transferred_length is also set 0 which is interpreted as success in nvme_fc_fcpio_done(). Let's inform the upper layer (nvme_fc_fcpio_done()) when something went wrong. nvme_fc_fcpio_done() maps all non-NVME_SC_SUCCESS status codes to NVME_SC_HOST_PATH_ERROR. There isn't any benefit to map the QLA status code to the NVMe status code. Therefore, use NVME_SC_INTERNAL to indicate an error which aligns it with the lpfc driver.

This reverts commit a43a67a2. This patch reverts the main part of switching direct io implementation to iomap infrastructure. There's a problem in invalidate page that couldn't be solved as regression in this development cycle. The problem occurs when buffered and direct io are mixed, and the ranges overlap. Although this is not recommended, filesystems implement measures or fallbacks to make it somehow work. In this case, fallback to buffered IO would be an option for btrfs (this already happens when direct io is done on compressed data), but the change would be needed in the iomap code, bringing new semantics to other filesystems. Another problem arises when again the buffered and direct ios are mixed, invalidation fails, then -EIO is set on the mapping and fsync will fail, though there's no real error. There have been discussions how to fix that, but revert seems to be the least intrusive option. Link: https://lore.kernel.org/linux-btrfs/20200528192103.xm45qoxqmkw7i5yl@fiona/Signed-off-by:

On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow unregistered mcast packets to pass. This happens, because ALE VLAN entries on these SoCs do not contain port masks for reg/unreg mcast packets, but instead store indexes of ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for reg/unreg mcast packets. This path was missed by commit 9d1f6447 ("net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled"). Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti(). Fixes: 9d1f6447 ("net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled") Signed-off-by:
