      scsi: mpt3sas: Fix unlock imbalance · cb551b8d
      Damien Le Moal authored 
      In BRM_status_show(), if the condition "!ioc->is_warpdrive" tested on entry
to the function is true, a "goto out" is called. This results in unlocking
ioc->pci_access_mutex without this mutex lock being taken.  This generates
the following splat:

      scsi: iscsi: Change iSCSI workqueue max_active back to 1 · 1a982620
      Bob Liu authored 
      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.

      scsi: mptscsih: Fix read sense data size · afe89f11
      Tomas Henzl authored 
      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.

      scsi: zfcp: Fix panic on ERP timeout for previously dismissed ERP action · 936e6b85
      Steffen Maier authored 
      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

      scsi: qla2xxx: Keep initiator ports after RSCN · 632f24f0
      Roman Bolshakov authored 
      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.

      scsi: qla2xxx: Set NVMe status code for failed NVMe FCP request · ef2e3ec5
      Daniel Wagner authored 
      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.

      The SafeSetID LSM uses the security_task_fix_setuid hook to filter
set*uid() syscalls according to its configured security policy. In
preparation for adding analagous support in the LSM for set*gid()

statements in the security_task_fix_setgid hook and seeing them get hit
during kernel boot.

      Revert "btrfs: switch to iomap_dio_rw() for dio" · 55e20bd1
      David Sterba authored 
      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.

      net: ethernet: ti: ale: fix allmulti for nu type ale · bc139119
      Grygorii Strashko authored 
      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().

  The big news is two new drivers (Nuvoton NPCM and Qualcomm CCI),
  larger refactoring of the Designware, Tegra, and PXA drivers, the
  Cadence driver supports being a slave now, and there is support to
  instanciate SPD eeproms for well-known cases (which will be
  user-visible because the i801 driver supports it), and some
  devm_platform_ioremap_resource() conversions which blow up the
  diffstat.

  Note that I applied the Nuvoton driver quite late, so some minor fixup
  patches arrived during the merge window. I chose to apply them right
  away because they were trivial"
