pscsi_map_sg() uses the variable nr_pages as a hint for bio_kmalloc() how many vector elements to allocate. If nr_pages is < BIO_MAX_PAGES, it will be reset to 0 after successful allocation of the bio. If bio_add_pc_page() fails later for whatever reason, pscsi_map_sg() tries to allocate another bio, passing nr_vecs = 0. This causes bio_add_pc_page() to fail immediately in the next call. pci_map_sg() continues to allocate zero-length bios until memory is exhausted and the kernel crashes with OOM. This can be easily observed by exporting a SATA DVD drive via pscsi. The target crashes as soon as the client tries to access the DVD LUN. In the case I analyzed, bio_add_pc_page() would fail because the DVD device's max_sectors_kb (128) was exceeded. Avoid this by simply not resetting nr_pages to 0 after allocating the bio. This way, the client receives an I/O error when it tries to send requests exceeding the devices max_sectors_kb, and eventually gets it right. The client must still limit max_sectors_kb e.g. by an udev rule if (like in my case) the driver doesn't report valid block limits, otherwise it encounters I/O errors.

Calling vha->hw->tgt.tgt_ops->free_cmd() from qlt_xmit_response() is wrong since the command for which a response is sent must remain valid until the SCSI target core calls .release_cmd(). It has been observed that the following scenario triggers a kernel crash: - qlt_xmit_response() calls qlt_check_reserve_free_req() - qlt_check_reserve_free_req() returns -EAGAIN - qlt_xmit_response() calls vha->hw->tgt.tgt_ops->free_cmd(cmd) - transport_handle_queue_full() tries to retransmit the response Fix this crash by reverting the patch that introduced it.

During MQ enablement of the ibmvfc driver ibmvfc_wait_for_ops() was missed. This function is responsible for waiting on commands to complete that match a certain criteria such as LUN or cancel key. The implementation as is only scans the CRQ for events ignoring any sub-queues and as a result will exit successfully without doing anything when operating in MQ channelized mode. Check the MQ and channel use flags to determine which queues are applicable, and scan each queue accordingly. Note in MQ mode SCSI commands are only issued down sub-queues and the CRQ is only used for driver specific management commands. As such the CRQ events are ignored when operating in MQ mode with channels.

For various EH activities the ibmvfc driver uses ibmvfc_wait_for_ops() to wait for the completion of commands that match a given criteria be it cancel key, or specific LUN. With recent changes commands are completed outside the lock in bulk by removing them from the sent list and adding them to a private completion list. This introduces a potential race in ibmvfc_wait_for_ops() since the criteria for a command to be outstanding is no longer simply being on the sent list, but instead not being on the free list. Avoid this race by scanning the entire command event pool and checking that any matching command that ibmvfc needs to wait on is not already on the free list.

A live partition migration (LPM) results in a CRQ disconnect similar to a hard reset. In this LPM case the hypervisor mostly preserves the CRQ transport such that it simply needs to be reenabled. However, the capabilities may have changed such as fewer channels, or no channels at all. Further, its possible that there may be sub-CRQ support, but no channel support. The CRQ reenable path currently doesn't take any of this into consideration. For simplicity release and reinitialize sub-CRQs during reenable, and set do_enquiry and using_channels with the appropriate values to trigger channel renegotiation.

The H_FREE_SUB_CRQ hypercall can return a retry delay return code that indicates the call needs to be retried after a specific amount of time delay. The error path to free a sub-CRQ in case of a failure during channel registration fails to capture the return code of H_FREE_SUB_CRQ which will result in the delay loop being skipped in the case of a retry delay return code. Store the return code result of the H_FREE_SUB_CRQ call such that the return code check in the delay loop evaluates a meaningful value. Also, use the rtas_busy_delay() to check the rc value and delay for the appropriate amount of time.

A non-zero return code for H_REG_SUB_CRQ is currently treated as a failure resulting in failing sub-CRQ setup. The case of H_CLOSED should not be treated as a failure. This return code translates to a successful sub-CRQ registration by the hypervisor, and is meant to communicate back that there is currently no partner VIOS CRQ connection established as of yet. This is a common occurrence during a disconnect where the client adapter can possibly come back up prior to the partner adapter. For non-zero return code from H_REG_SUB_CRQ treat a H_CLOSED as success so that sub-CRQs are successfully setup.

A hard reset results in a complete transport disconnect such that the CRQ connection with the partner VIOS is broken. This has the side effect of also invalidating the associated sub-CRQs. The current code assumes that the sub-CRQs are perserved resulting in a protocol violation after trying to reconnect them with the VIOS. This introduces an infinite loop such that the VIOS forces a disconnect after each subsequent attempt to re-register with invalid handles. Avoid the aforementioned issue by releasing the sub-CRQs prior to CRQ disconnect, and driving a reinitialization of the sub-CRQs once a new CRQ is registered with the hypervisor.

If ibmvfc_init_sub_crqs() fails ibmvfc_probe() simply parrots registration failure reported elsewhere, and futher vhost->scsi_scrq.scrq == NULL is indication enough to the driver that it has no sub-CRQs available. The mq_enabled check can also be moved into ibmvfc_init_sub_crqs() such that each caller doesn't have to gate the call with a mq_enabled check. Finally, in the case of sub-CRQ setup failure setting do_enquiry can be turned off to putting the driver into single queue fallback mode. The aforementioned changes also simplify the next patch in the series that fixes a hard reset issue, by tying a sub-CRQ setup failure and do_enquiry logic into ibmvfc_init_sub_crqs().

Sergei and John both reported that ia64 failed to boot in 5.11, and it was related to signals. Turns out the ia64 signal handling is a bit odd, it doesn't check the return value of get_signal() for whether there's a signal to deliver or not. With the introduction of TIF_NOTIFY_SIGNAL, then task_work could trigger it. Fix it by only calling handle_signal() if we actually have a real signal to deliver. This brings it in line with all other archs, too. Fixes: b269c229 ("ia64: add support for TIF_NOTIFY_SIGNAL") Reported-by:

Commit 78d3bb44 ("kbuild: Fix <linux/version.h> for empty SUBLEVEL or PATCHLEVEL") fixed the build error for empty SUBLEVEL or PATCHLEVEL by prepending a zero. Commit 9b82f13e ("kbuild: clamp SUBLEVEL to 255") re-introduced this issue. This time, we cannot take the same approach because we have C code: #define LINUX_VERSION_PATCHLEVEL $(PATCHLEVEL) #define LINUX_VERSION_SUBLEVEL $(SUBLEVEL) Replace empty SUBLEVEL/PATCHLEVEL with a zero.

'make -s' should be really silent. However, 'make -s V=1' prints noisy log messages from some shell scripts. Of course, such a combination is odd, but the build system needs to do the right thing even if a user gives strange input. If -s is given, KBUILD_VERBOSE should be forced to 0. Signed-off-by:
