Devlink instance lifetime was linked to qed_dev object. That caused devlink to be recreated on each recovery. Change it by making higher level driver (qede) responsible for lifetime management. This way devlink survives recoveries. qede now stores devlink structure pointer as a part of its device object, devlink private data contains a linkage structure, qed_devlink.

The driver neglects to check the result of platform_get_irq()'s call and blithely passes the negative error codes to request_irq() (which takes *unsigned* IRQ #s), causing it to fail with -EINVAL (overridden by -ENODEV further below).

The debugfs snapshot should be executed before the reset occurs to ensure that the register contents are saved properly. As such, it is incorrect to queue the debugfs dump when running a reset as the reset will occur prior to the snapshot work item is handler. Therefore, directly snapshot registers in the reset work handler. Link: https://lore.kernel.org/r/1617709711-195853-5-git-send-email-john.garry@huawei.comSigned-off-by:

The for-loop iterates with a u8 loop counter i and compares this with the loop upper limit of pm8001_ha->max_q_num which is a u32 type. There is a potential infinite loop if pm8001_ha->max_q_num is larger than the u8 loop counter. Fix this by making the loop counter the same type as pm8001_ha->max_q_num. [mkp: this is purely theoretical, max_q_num is currently limited to 64] Link: https://lore.kernel.org/r/20210407135840.494747-1-colin.king@canonical.com Fixes: 65df7d19 ("scsi: pm80xx: Fix chip initialization failure") Addresses-Coverity: ("Infinite loop") Reviewed-by:

The mpi_uninit_check() takes longer for inbound doorbell register to be cleared. Increase the timeout substantially so that the driver does not fail to load. Previously, the inbound doorbell wait time was mistakenly increased in the mpi_init_check() instead of mpi_uninit_check(). It is okay to leave the mpi_init_check() wait time as-is as these are timeout values and if there is a failure, waiting longer is not an issue.

Change tcmu to support DATA_BLOCK_SIZE being a multiple of PAGE_SIZE. There are two reasons why one would like to have a bigger DATA_BLOCK_SIZE: 1) If userspace - e.g. due to data compression, encryption or deduplication - needs to have receive or transmit data in a consecutive buffer, we can define DATA_BLOCK_SIZE to the maximum size of a SCSI READ/WRITE to enforce that userspace sees just one consecutive buffer. That way we can avoid the need for doing data copy in userspace. 2) Using a bigger data block size can speed up command processing in tcmu. The number of free data blocks to look up in bitmap is reduced substantially. The lookup for data pages in radix_tree can be done more efficiently if there are multiple pages in a data block. The maximum number of IOVs to set up is lower so cmd entries in the ring become smaller. Link: https://lore.kernel.org/r/20210324195758.2021-4-bostroesser@gmail.comSigned-off-by: -

Rename some variables and definitions as a first preparation for DATA_BLOCK_SIZE != PAGE_SIZE and add the new DATA_PAGES_PER_BLK definition containing the number of pages per data block. Rename tcmu_try_get_block_page() to tcmu_try_get_data_page(). Keep name tcmu_get_block_page() since it will go away in a following commit when there is only one caller left. Subsequent commits will then add full support for DATA_PAGES_PER_BLK != 1, which also means DATA_BLOCK_SIZE = DATA_PAGES_PER_BLK * PAGE_SIZE Link: https://lore.kernel.org/r/20210324195758.2021-3-bostroesser@gmail.comSigned-off-by:

Some definitions and members of struct tcmu_dev had misleading names. Examples: - ring_size was used for the size of mailbox + cmd ring + data area - CMDR_SIZE was used for size of mailbox + cmd ring I added the new definition MB_CMDR_SIZE (mailbox + command ring), changed CMDR_SIZE to hold the size of the command ring only and replaced in struct tcmu_dev the member ring_size with mmap_pages, because the member is now used in tcmu_mmap() only, where we need page count, not size. I also added the new struct tcmu_dev member 'cmdr' which is used to replace some occurences of '(void *)mb + CMDR_OFF' with 'udev->cmdr' for better readability.

The problem is that the original code is trying to copy data into a bunch of struct members adjacent to each other in a single call to memcpy(). Now that a new struct _upiu_req_ enclosing all those adjacent members is introduced, memcpy() doesn't overrun the length of &treq.req_header, because the address of the new struct object _upiu_req_ is used as the destination, instead. The same problem is present when memcpy() overruns the length of the source &treq.rsp_header; in this case the address of the new struct object _upiu_rsp_ is used, instead. Also, this helps with the ongoing efforts to enable -Warray-bounds and avoid confusing the compiler.

While diag reset is in progress there is short duration where all access to controller's PCI config space from the host needs to be blocked. This is due to a hardware limitation of the IOC controllers. Block all access to controller's config space from userland applications by calling pci_cfg_access_lock() while diag reset is in progress and unlocking it again after the controller comes back to ready state.
