The _scsih_pci_mmio_enabled called if scsih_pci_error_detected returns PCI_ERS_RESULT_CAN_RECOVER, at this point, read/write to the device still works, no need to reset slot. Or the mpt3sas_base_map_resources in scsih_pci_slot_reset will fail, and iounamp ioc->chip, then we will meet issue when read ioc->chip in mpt3sas_base_get_iocstate from _base_fault_reset_work.

qla2xxx first calls request_irq() and then does the setup of the queue entry data needed in the interrupt handlers in when using MSI-X. This could lead to a NULL pointer dereference when an IRQ fires between the request_irq() call and the assignment of the qentry data structure to the rsp->msix field. A possible case for such a race would be in the kdump case when the HBA's IRQs are still enabled but the driver is undergoing a new initialisation and thus is not aware of already activated IRQs in the HBA.

There was an issue reported by Lucz Geza on Dell Perc 6i. As per issue reported, megaraid_sas driver goes into an infinite error reporting loop as soon as there is a change in the status of one of the arrays (degrade, resync online etc ). Below are the error logs reported continuously- Jun 25 08:49:30 ns8 kernel: [ 757.757017] megaraid_sas 0000:02:00.0: DCMD failed/not supported by firmware: megasas_get_pd_list 4115 Jun 25 08:49:30 ns8 kernel: [ 757.778017] megaraid_sas 0000:02:00.0: DCMD failed/not supported by firmware: megasas_get_pd_list 4115 Jun 25 08:49:30 ns8 kernel: [ 757.799017] megaraid_sas 0000:02:00.0: DCMD failed/not supported by firmware: megasas_get_pd_list 4115 Jun 25 08:49:30 ns8 kernel: [ 757.820018] megaraid_sas 0000:02:00.0: DCMD failed/not supported by firmware: megasas_get_pd_list 4115 Jun 25 08:49:30 ns8 kernel: [ 757.841018] megaraid_sas 0000:02:00.0: DCMD failed/not supported by firmware: megasas_get_pd_list 4115 This issue is very much specific to controllers which do not support DCMD- MR_DCMD_PD_LIST_QUERY. In case of any hotplugging/rescanning of drives, AEN thread will be scheduled by driver and fire DCMD- MR_DCMD_PD_LIST_QUERY and if this DCMD is failed then driver will fail this event processing and will not go ahead for further events. This will cause infinite loop of same event getting retried infinitely and causing above mentioned logs. Fix for this problem is: not to fire DCMD MR_DCMD_PD_LIST_QUERY for controllers which do not support it and send DCMD SUCCESS status to AEN function so that it can go ahead with other event processing.

In the receive path libfc extracts a cpu number from the ox_id in the fiber channel header and uses that to do a per_cpu_ptr conversion. If, for some reason, a frame is received with an invalid ox_id, per_cpu_ptr will return an invalid pointer and the libfc receive path will panic the system trying to use it. I'm currently looking at such a case, and I don't yet know why a cpu number > nr_cpu_ids is appearing in an exchange id. But adding a sanity check in libfc prevents a system panic, and seems like good idea when dealing with frames coming in from the network. Signed-off-by:

The driver creates its own per-CPU threads which are updated based on CPU hotplug events. It is also possible to use kworkers and remove some of the kthread infrastrucure. The code checked ->thread to decide if there is an active per-CPU thread. By using the kworker infrastructure this is no longer possible (or required). The thread pointer is saved in `kthread' instead of `thread' so anything trying to use thread is caught by the compiler. Currently only the bnx2fc driver is using struct fcoe_percpu_s and the kthread member. After a CPU went offline, we may still enqueue items on the "offline" CPU. This isn't much of a problem. The work will be done on a random CPU. The allocated crc_eof_page page won't be cleaned up. It is probably expected that the CPU comes up at some point so it should not be a problem. The crc_eof_page memory is released of course once the module is removed. This patch was only compile-tested due to -ENODEV. Cc: Vasu Dev <vasu.dev@intel.com> Cc: "James E.J.

Enabling format checking in dprintk() shows that wd7000_biosparam uses an incorrect format string for sector_t: drivers/scsi/wd7000.c: In function 'wd7000_biosparam': drivers/scsi/wd7000.c:1594:21: error: format '%d' expects argument of type 'int', but argument 3 has type 'sector_t {aka long long unsigned int}' [-Werror=format=] As sector_t can be 32-bit wide, this adds a cast to 'u64' and prints that with the correct format. The change to use no_printk() generally helps with finding this kind of hidden format string bug, and I found that when building with "-Wextra", which warned about an empty else clause in } else dprintk("ok!\n"); Signed-off-by:Arnd Bergmann <arnd@arndb.de> Signed-off-by:

The fc_get_host_stats() function contains a complex conversion from jiffies to timespec to seconds. As we try to get rid of uses of struct timespec, we can clean this up and replace it with a simpler computation. Simply dividing the difference in jiffies by HZ is not only much more efficient, it also avoids a problem that causes the seconds_since_last_reset value to be incorrect if jiffies has overrun since the 'boot_time' value was recorded.

Some CXL Flash cards need notification of device shutdown in order to flush pending I/Os. A PCI notification hook for shutdown has been added where the driver notifies the card and returns. When the device is removed in the PCI remove path, notification code will wait for shutdown processing to complete. Signed-off-by:

Device dependent flags are needed to support functions that are specific to a particular device. One such case is - some CXL Flash cards need to be notified of device shutdown. For other CXL devices, this feature does not prove to be useful yet. Such distinct features need to be identified in the driver to bypass or invoke specific functionality. In this patch, a member 'flags' has been added to device dependent values. These flags will be used and expanded in the future to support various device specific functions. Signed-off-by:

While running 'sg_reset -H' in a loop with a user-space application active, hit the following exception: cpu 0x2: Vector: 300 (Data Access) pc: : afu_attach+0x50/0x240 [cxlflash] lr: : cxlflash_afu_recover+0x3dc/0x7d0 [cxlflash] pid = 20365, comm = run_block_fvt Linux version 4.5.0-491-26f710d+ cxlflash_afu_recover+0x3dc/0x7d0 [cxlflash] cxlflash_ioctl+0x5a8/0x6f0 [cxlflash] scsi_ioctl+0x3b0/0x4c0 sd_ioctl+0x110/0x190 blkdev_ioctl+0x28c/0xc20 block_ioctl+0xa4/0xd0 do_vfs_ioctl+0xd8/0x8c0 SyS_ioctl+0xd4/0xf0 system_call+0x38/0xb4 The problem here is that the problem space area is unmapped while the application issues the DK_CXLFLASH_RECOVER_AFU ioctl. This is the order I observe: proc1 proc2 1) sg_reset 2) ioctl(DK_CXLFLASH_RECOVER_AFU) 3) sg_reset again causing a PSA unmap 4) continues RECOVER_AFU processing The resolution to this problem is to have the reset handler drain all outstanding user space initiated ioctls before proceeding. It is safe to drain after the state has been changed to STATE_RESET. Also since drain_ioctls() was static, it had to be moved up a bit to be before cxlflash_eh_host_reset_handler(). Signed-off-by: -

In this post: http://www.spinics.net/lists/linux-scsi/msg97124.html the author shows some kernel infrastructure complaining about a sleep in an invalid context. Remove offending call to vmalloc(). Instead of using kzalloc() which reviewers didn't like, use a bucket system (64 bytes on the stack) and potentially multiple calls to sg_pcopy_from_buffer() to construct the 'data-in' buffer for the SCSI REPORT LUNS command.
