e7f7b6f38a scsi: lpfc: change snprintf to scnprintf for possible overflow
Change snprintf to scnprintf. There are generally two cases where using
snprintf causes problems.

1) Uses of size += snprintf(buf, SIZE - size, fmt, ...)
In this case, if snprintf would have written more characters than what the
buffer size (SIZE) is, then size will end up larger than SIZE. In later
uses of snprintf, SIZE - size will result in a negative number, leading
to problems. Note that size might already be too large by using
size = snprintf before the code reaches a case of size += snprintf.

2) If size is ultimately used as a length parameter for a copy back to user
space, then it will potentially allow for a buffer overflow and information
disclosure when size is greater than SIZE. When the size is used to index
the buffer directly, we can have memory corruption. This also means when
size = snprintf... is used, it may also cause problems since size may become
large.  Copying to userspace is mitigated by the HARDENED_USERCOPY kernel
configuration.

The solution to these issues is to use scnprintf which returns the number of
characters actually written to the buffer, so the size variable will never
exceed SIZE.

c2fe742ff6 scsi: mpt3sas: Fix kernel panic during expander reset
During expander reset handling, the driver invokes kernel function
scsi_host_find_tag() to obtain outstanding requests associated with the
scsi host managed by the driver. Driver loops from tag value zero to hba
queue depth to obtain the outstanding scmds. But when blk-mq is enabled,
the block layer may return stale entry for one or more requests. This may
lead to kernel panic if the returned value is inaccessible or the memory
pointed by the returned value is reused.

Reference of upstream discussion:

	https://patchwork.kernel.org/patch/10734933/

Instead of calling scsi_host_find_tag() API for each and every smid (smid
is tag +1) from one to shost->can_queue, now driver will call this API (to
obtain the outstanding scmd) only for those smid's which are outstanding at
the driver level.

Driver will determine whether this smid is outstanding at driver level by
looking into it's corresponding MPI request frame, if its MPI request frame
is empty, then it means that this smid is free and does not need to call
scsi_host_find_tag() for it.  By doing this, driver will invoke
scsi_host_find_tag() for only those tags which are outstanding at the
driver level.

Driver will check whether particular MPI request frame is empty or not by
looking into the "DevHandle" field. If this field is zero then it means
that this MPI request is empty. For active MPI request DevHandle must be
non-zero.

Also driver will memset the MPI request frame once the corresponding scmd
is processed (i.e. just before calling
scmd->done function).

7f5203c13b scsi: ibmvscsi: Fix empty event pool access during host removal
The event pool used for queueing commands is destroyed fairly early in the

scsi_remove_host() it is possible for further calls to queuecommand to be

The kernel buffer log is overfilled with this log:

[11261.952732] ibmvscsi: found no event struct in pool!

This patch reorders the operations during host teardown. Start by calling
the SRP transport and Scsi_Host remove functions to flush any outstanding
work and set the host offline. LLDD teardown follows including destruction
of the event pool, freeing the Command Response Queue (CRQ), and unmapping
any persistent buffers. The event pool destruction is protected by the
scsi_host lock, and the pool is purged prior of any requests for which we
never received a response. Finally, move the removal of the scsi host from
our global list to the end so that the host is easily locatable for
debugging purposes during teardown.

In commit ffb1c820b8 ("scsi: hisi_sas: remove the check of sas_dev status

We need to always follow an internal abort with a software reset, as per HW
programming flow, so add this.

Commit 7f147f9bfd ("scsi: qla2xxx: Fix N2N target discovery with Local

used for FC-AL discovery as well. Added check to make sure we are bypassing
area and domain check only in N2N topology for target discovery.

17605afaae scsi: core: Avoid that a kernel warning appears during system resume
Since scsi_device_quiesce() skips SCSI devices that have another state than
RUNNING, OFFLINE or TRANSPORT_OFFLINE, scsi_device_resume() should not
complain about SCSI devices that have been skipped. Hence this patch.  This
patch avoids that the following warning appears during resume:
