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 5c5a7680 ("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.

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. Signed-off-by:

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. Co-developed-by:

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. Link: https://lore.kernel.org/r/20231129165832.224100-1-hare@kernel.orgSigned-off-by:

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. Signed-off-by:

We should set the status to FC_TIMED_OUT when a timeout error is passed to fc_fcp_rec_error(). Signed-off-by:

Hannes Reinecke authored
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. Signed-off-by:

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 471d7ff8 ("powerpc/64s: Remove POWER4 support"). So drop the check. That makes the "testmode" module parameter unused, so remove it as well. Signed-off-by:

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.

strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated[1]. Additionally, it returns the size of the source string, not the resulting size of the destination string. In an effort to remove strlcpy() completely[2], replace strlcpy() here with strscpy(). Overflow should be impossible here, but actually check for buffer sizes being identical with BUILD_BUG_ON(), and include a run-time check as well.
