We have two reports of failed memory allocation in btrfs' code which is calling into report zones. Both of these reports have the following signature coming from __vmalloc_area_node(): kworker/u17:5: vmalloc error: size 0, failed to allocate pages, mode:0x10dc2(GFP_KERNEL|__GFP_HIGHMEM|__GFP_NORETRY|__GFP_ZERO), nodemask=(null),cpuset=/,mems_allowed=0 Further debugging showed these where allocations of one sector (512 bytes) and at least one of the reporter's systems where low on memory, so going through the overhead of allocating a vm area failed. Switching the allocation from __vmalloc() to kvzalloc() avoids the overhead of vmalloc() on small allocations and succeeds. Note: the buffer is already freed using kvfree() so there's no need to adjust the free path.

If the sg_copy_buffer() call returns less than sdebug_sector_size, then we drop out of the copy loop. However, we still report that we copied the full expected amount, which is not proper. Fix by keeping a running total and return that value.

A sanity check on phy_mask was added in commit 3668651def2c ("scsi: mpi3mr: Sanitise num_phys"). This causes warning messages when more than 64 phys are detected and devices connected to phys greater than 64 are dropped. The phy_mask bitmap is only needed for controller phys and not required for expander phys. Controller phys can go up to a maximum of 64 and therefore u64 is good enough to contain phy_mask bitmap. To suppress those warnings and allow devices to be discovered as before the offending commit, restrict the phy_mask setting and lowest phy setting only to the controller phys.

The only input fc_rport_set_marginal_state() currently accepts is "Marginal" when port_state is "Online", and "Online" when the port_state is "Marginal". It should also allow setting port_state to its current state, either "Marginal or "Online".

scsi: wd33c93: Don't use stale scsi_pointer value

2024-10-04T01:48:08Z

A regression was introduced with commit dbb2da557a6a ("scsi: wd33c93: Move the SCSI pointer to private command data") which results in an oops in wd33c93_intr(). That commit added the scsi_pointer variable and initialized it from hostdata->connected. However, during selection, hostdata->connected is not yet valid. Fix this by getting the current scsi_pointer from hostdata->selecting.

scsi: fnic: Move flush_work initialization out of if block

2024-10-04T01:45:11Z

After commit 379a58caa199 ("scsi: fnic: Move fnic_fnic_flush_tx() to a work queue"), it can happen that a work item is sent to an uninitialized work queue. This may has the effect that the item being queued is never actually queued, and any further actions depending on it will not proceed. The following warning is observed while the fnic driver is loaded: kernel: WARNING: CPU: 11 PID: 0 at ../kernel/workqueue.c:1524 __queue_work+0x373/0x410 kernel: kernel: queue_work_on+0x3a/0x50 kernel: fnic_wq_copy_cmpl_handler+0x54a/0x730 [fnic 62fbff0c42e7fb825c60a55cde2fb91facb2ed24] kernel: fnic_isr_msix_wq_copy+0x2d/0x60 [fnic 62fbff0c42e7fb825c60a55cde2fb91facb2ed24] kernel: __handle_irq_event_percpu+0x36/0x1a0 kernel: handle_irq_event_percpu+0x30/0x70 kernel: handle_irq_event+0x34/0x60 kernel: handle_edge_irq+0x7e/0x1a0 kernel: __common_interrupt+0x3b/0xb0 kernel: common_interrupt+0x58/0xa0 kernel: It has been observed that this may break the rediscovery of Fibre Channel devices after a temporary fabric failure.
