2016-07-12net: ethoc: Correctly pad short packetsFlorian Fainelli
Even though the hardware can be doing zero padding, we want the SKB to be going out on the wire with the appropriate size. This fixes packet truncations observed with e.g: ARP packets. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-07-12net: ethoc: Fix early error pathsFlorian Fainelli
In case any operation fails before we can successfully go the point where we would register a MDIO bus, we would be going to an error label which involves unregistering then freeing this yet to be created MDIO bus. Update all error paths to go to label free which is the only one valid until either the clock is enabled, or the MDIO bus is allocated and registered. This fixes kernel oops observed while trying to dereference the MDIO bus structure which is not yet allocated. Fixes: a1702857724f ("net: Add support for the OpenCores 10/100 Mbps Ethernet MAC.")

2016-07-12fcoe: convert to kworkerSebastian Andrzej Siewior
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.

2016-07-12scsi: libfc: fix seconds_since_last_reset calculationArnd Bergmann
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.

2016-07-12cxlflash: Add device dependent flagsUma Krishnan
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.

2016-07-12cxlflash: Fix to drain operations from previous resetManoj N. Kumar
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().

2016-07-12libfc: Update rport reference countingHannes Reinecke
Originally libfc would just be initializing the refcount to '1', and using the disc_mutex to synchronize if and when the final put should be happening. This has a race condition as the mutex might be delayed, causing other threads to access an invalid structure. This patch updates the rport reference counting to increase the reference every time 'rport_lookup' is called, and decreases the reference correspondingly. This removes the need to hold 'disc_mutex' when removing the structure, and avoids the above race condition.

2016-07-12pmem: kill __pmem address spaceDan Williams
The __pmem address space was meant to annotate codepaths that touch persistent memory and need to coordinate a call to wmb_pmem(). Now that wmb_pmem() is gone, there is little need to keep this annotation.

2016-07-12nvme: Limit command retriesKeith Busch
Many controller implementations will return errors to commands that will not succeed, but without the DNR bit set. The driver previously retried these commands an unlimited number of times until the command timeout has exceeded, which takes an unnecessarilly long period of time. This patch limits the number of retries a command can have, defaulting to 5, but is user tunable at load or runtime. The struct request's 'retries' field is used to track the number of retries attempted. This is in contrast with scsi's use of this field, which indicates how many retries are allowed.
