      scsi: qedf: fixup locking in qedf_restart_rport() · 6d1368e8
      Hannes Reinecke authored
      fc_rport_create() needs to be called with disc_mutex held.  And we should
      re-assign the 'rdata' pointer in case it got changed.

      scsi: qedf: missing kref_put in qedf_xmit() · 4262d35c
      Hannes Reinecke authored
      qedf_xmit() calls fc_rport_lookup(), but discards the returned rdata
      structure almost immediately without decreasing the refcount.  This leads
      to a refcount leak and the rdata never to be freed.

      scsi: qedf: Add missing fc_disc_init call after allocating lport · 0cbd0075
      Chad Dupuis authored
      When receiving an unsolicited frame we could crash on a list traversal in
      fc_rport_lookup while searching the rport which is associated with our
      lport.
      
      Initialize the lport's discovery node after allocating the lport in
      __qedf_probe().

      Chad Dupuis authored
       - If a TMF and cleanup are issued at the same time they could cause a call
         trace if issued against the same xid as the io_req->tm_done completion

      scsi: qedf: Modify abort and tmf handler to handle edge condition and flush · 69ef2c69
      Saurav Kashyap authored
      An I/O can be in any state when flush is called, it can be in abort,
      waiting for abort, RRQ send and waiting or TMF send.
      
       - HZ can be different on different architecture, correctly set abort
         timeout value.
      
       - Flush can complete the I/Os prematurely, handle refcount for aborted
         I/Os and for which RRQ is pending.
      
       - Differentiate LUN/TARGET reset, as cleanup needs to be send to firmware
         accordingly.
      
       - Add flush mutex to sync cleanup call from abort and flush routine.
      
       - Clear abort/outstanding bit on timeout.

      scsi: qedf: Modify flush routine to handle all I/Os and TMF · 5d5e5565
      Shyam Sundar authored
      The purpose of flush routine is to cleanup I/Os to the firmware and
      complete them to scsi middle layer. This routine is invoked before
      connection is uploaded because of rport going away.
      
       - Don't process any I/Os, aborts, TMFs coming when flush in progress.
      
       - Add flags to handle cleanup and release of I/Os because flush can
         prematurely complete I/Os.
      
       - Original command can get completed to driver when cleanup for same is
         posted to firmware, handle this condition.
      
       - Modify flush to handle I/Os in all the states like abort, TMF, RRQ and
         timeouts.

      scsi: qedf: Simplify s/g list mapping · 3e2c11b3
      Chad Dupuis authored
      When mapping the pages from a scatter/gather list from the SCSI layer we
      only need to follow these rules:
      
       - Max SGEs for each I/O request is 256
       - No size limit on each SGE
       - No need to split OS provided SGEs to 4K before sending to firmware.
       - Slow SGE is applicable only when:
         - There are > 8 SGEs and any middle SGE is less than a page size (4K)
      
      Make necessary changes so that driver follows these rules. Applicable only
      for Write requests (not for Read requests). No need to check SGE address
      alignment requirements (first, middle or last) before declaring slow SGE.

      scsi: qla2xxx: Simplify conditional check again · 46333ceb
      Nathan Chancellor authored
      Clang warns when it sees a logical not on the left side of a conditional
      statement because it thinks the logical not should be applied to the whole
      statement, not just the left side:
      
      drivers/scsi/qla2xxx/qla_nx.c:3703:7: warning: logical not is only
      applied to the left hand side of this comparison
      [-Wlogical-not-parentheses]
      
      This particular instance was already fixed by commit 0bfe7d3c ("scsi:
      qla2xxx: Simplify conditional check") upstream but it was reintroduced by
      commit 3695310e ("scsi: qla2xxx: Update flash read/write routine") in
      the 5.2/scsi-queue.

      scsi: sd: Rely on the driver core for asynchronous probing · 21e6ba3f
      Bart Van Assche authored
      As explained during the 2018 LSF/MM session about increasing SCSI disk
      probing concurrency, the problems with the current probing approach are as
      follows:
      
      - The driver core is unaware of asynchronous SCSI LUN probing.
        wait_for_device_probe() waits for all asynchronous probes except
        asynchronous SCSI disk probes.
      
      - There is unnecessary serialization between sd_probe() and sd_remove().
        This can lead to a deadlock.
      
      Hence this patch that modifies the sd driver such that it uses the driver
      core framework for asynchronous probing. The async domains and
      get_device()/put_device() pairs that became superfluous due to this change
      are removed.
      
      This patch does not affect the time needed for loading the scsi_debug
      kernel module with parameters delay=0 and max_luns=256.
      
      This patch depends on commit ef0ff683 ("driver core: Probe devices
      asynchronously instead of the driver") that went upstream in kernel version
      v5.1-rc1.

      scsi: libcxgbi: remove uninitialized variable len · 83785733
      Colin Ian King authored
      The variable len is not being inintialized and the uninitialized value is
      being returned. However, this return path is never reached because the
      default case in the switch statement returns -ENOSYS.  Clean up the code by
      replacing the return -ENOSYS with a break for the default case and
      returning -ENOSYS at the end of the function.  This allows len to be
      removed.
