Uwe Kleine-König <u.kleine-koenig@pengutronix.de> says:
Hello,
this series converts all drivers below drivers/scsi to struct
platform_driver::remove_new(). See commit 5c5a7680e67b ("platform:
Provide a remove callback that returns no value") for an extended
explanation and the eventual goal.
All conversations are trivial, because all .remove() callbacks returned
zero unconditionally.
Best regards
Uwe

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
In the error path emit an error message replacing the (less useful)
message by the core. Apart from the improved error message there is no
change in behaviour.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The driver now supports SGLs for BSG data transfer. Upon loading, the
driver pre-allocates SGLs in chunks of 8k, results in a total of 256 * 8k,
equal to 2MB. These pre-allocated SGLs are reserved for handling BSG
commands and are deallocated during driver unload.

Hannes Reinecke <hare@kernel.org> says:
Hi all,
when testing command timeout with the help of XDP I found that
scsi_try_to_abort_cmd() would always return 'SUCCESS' for FCoE, even
if no commands could be sent over the wire. Which is not only
surprising, but also can lead to data corruption as commands were
never aborted. Root cause was that aborts had been sent twice, once
from FC error recovery and once from SCSI EH, with the former inducing
the latter to assume that the command was already aborted.
As usual, comments and reviews are welcome.

When an exchange is completed with FC_TIMED_OUT we should map it to
DID_TIME_OUT to inform the SCSI midlayer that this was a command timeout;
DID_BUS_BUSY implies that the command was never sent which is not the case
here.

The current FC error recovery is sending up to three REC (recovery) frames
in 10 second intervals, and as a final step sending an ABTS after 30
seconds for the command itself. Unfortunately sending an ABTS is also the
action for the SCSI abort handler, and the default timeout for SCSI
commands is also 30 seconds. This causes two ABTS to be scheduled, with the
libfc one slightly earlier. The ABTS scheduled by SCSI EH then sees the
command to be already aborted, and will always return with a 'GOOD' status
irrespective on the actual result from the first ABTS. This causes the
SCSI EH abort handler to always succeed, and SCSI EH never to be engaged.
Fix this by not issuing an ABTS when a SCSI command is present for the
exchange, but rather wait for the abort scheduled from SCSI EH. And warn
if an abort is already scheduled to avoid similar errors in the future.

aic7770_config() returns both negative and positive error codes. It's
better to make aic7770_probe() only return negative error codes.
A previous commit made ahc_linux_register_host() return negative error
codes, which makes sure aic7770_probe() returns negative error codes.

ahc_linux_register_host() can return an error code in case of failure. So
ahc_linux_pci_dev_probe() should return the value of
ahc_linux_register_host() rather than zero.
An earlier commit made ahc_linux_register_host() return negative error
codes, which makes sure ahc_linux_pci_dev_probe() returns negative error
codes.

The IPR driver has a routine to check whether it's running on certain CPU
versions and if so whether the adapter is supported on that CPU.
But none of the CPUs it checks for are supported by Linux anymore.
The most recent CPU it checks for is Power4+ which was removed in commit
471d7ff8b51b ("powerpc/64s: Remove POWER4 support").
So drop the check. That makes the "testmode" module parameter unused, so
remove it as well.

strncpy() is deprecated for use on NUL-terminated destination strings [1]
and as such we should prefer more robust and less ambiguous string
interfaces.
We expect partition_name to be NUL-terminated based on its usage with
format strings:
| dev_info(hostdata->dev, "host srp version: %s, "
| "host partition %s (%d), OS %d, max io %u\n",
| hostdata->madapter_info.srp_version,
| hostdata->madapter_info.partition_name,
| be32_to_cpu(hostdata->madapter_info.partition_number),
| be32_to_cpu(hostdata->madapter_info.os_type),
| be32_to_cpu(hostdata->madapter_info.port_max_txu[0]));
...
| len = snprintf(buf, PAGE_SIZE, "%s\n",
| hostdata->madapter_info.partition_name);
Moreover, NUL-padding is not required as madapter_info is explicitly
memset to 0:
| memset(&hostdata->madapter_info, 0x00,
| sizeof(hostdata->madapter_info));
Considering the above, a suitable replacement is strscpy() [2] due to the
fact that it guarantees NUL-termination on the destination buffer without
unnecessarily NUL-padding.

strncpy() is deprecated for use on NUL-terminated destination strings [1]
and as such we should prefer more robust and less ambiguous string
interfaces.
We expect these fields to be NUL-terminated as the property names from
which they are derived are also NUL-terminated.
Moreover, NUL-padding is not required as our destination buffers are
already NUL-allocated and any future NUL-byte assignments are redundant
(like the ones that strncpy() does).
ibmvfc_probe() ->
| struct ibmvfc_host *vhost;
| struct Scsi_Host *shost;
...
| shost = scsi_host_alloc(&driver_template, sizeof(*vhost));
... **side note: is this a bug? Looks like a type to me ^^^^^**
...
| vhost = shost_priv(shost);
... where shost_priv() is:
| static inline void *shost_priv(struct Scsi_Host *shost)
| {
| return (void *)shost->hostdata;
| }
.. and:
scsi_host_alloc() ->
| shost = kzalloc(sizeof(struct Scsi_Host) + privsize, GFP_KERNEL);
And for login_info->..., NUL-padding is also not required as it is
explicitly memset to 0:
| memset(login_info, 0, sizeof(*login_info));
Considering the above, a suitable replacement is strscpy() [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.
