2018-12-19scsi: lpfc: Adding ability to reset chip via pci bus resetJames Smart
This patch adds a "pci_bus_reset" option to the board_mode sysfs attribute. This option uses the pci_reset_bus() api to reset the PCIe link the adapter is on, which will reset the chip/adapter. Prior to issuing this option, all functions on the same chip must be placed in the offline state by the admin. After the reset, all of the instances may be brought online again. The primary purpose of this functionality is to support cases where firmware update required a chip reset but the admin did not want to reboot the machine in order to instantiate the firmware update. Sanity checks take place prior to the reset to ensure the adapter is the sole entity on the PCIe bus and that all functions are in the offline state.

2018-12-19scsi: lpfc: Fix discovery failure when PLOGI is deferedJames Smart
When a target's link dropped, an RSCN was received to communicate the change. The driver detected the loss of the target and issued and UNREG_RPI mailbox command. While that was being processed, another RSCN was received to communicate the port coming back. The driver deferred the PLOGI to the port until the mailbox command finishes. When the mailbox command completed it saw the pending port and called the routines to issue the PLOGI. However, it forgot to clear the UNREG_INP state flag, so the PLOGI xmt routine nooped the PLOGI request assuming it needed to wait for the mailbox command. At this point, login would never be re-attempted. Clear UNREG_INP before issuing the deferred PLOGI.

2018-12-19scsi: lpfc: update fault value on successful trunk events.James Smart

2018-12-19scsi: mpt3sas: fix memory ordering on 64bit writesStephan Günther
With commit 09c2f95ad404 ("scsi: mpt3sas: Swap I/O memory read value back to cpu endianness"), 64bit writes in _base_writeq() were rewritten to use __raw_writeq() instad of writeq(). This introduced a bug apparent on powerpc64 systems such as the Raptor Talos II that causes the HBA to drop from the PCIe bus under heavy load and being reinitialized after a couple of seconds. It can easily be triggered on affacted systems by using something like fio --name=random-write --iodepth=4 --rw=randwrite --bs=4k --direct=0 \ --size=128M --numjobs=64 --end_fsync=1 fio --name=random-write --iodepth=4 --rw=randwrite --bs=64k --direct=0 \ --size=128M --numjobs=64 --end_fsync=1 a couple of times. In my case I tested it on both a ZFS raidz2 and a btrfs raid6 using LSI 9300-8i and 9400-8i controllers. The fix consists in resembling the write ordering of writeq() by adding a mandatory write memory barrier before device access and a compiler barrier afterwards. The additional MMIO barrier is superfluous.

2018-12-19scsi: qla2xxx: deadlock by configfs_depend_itemAnatoliy Glagolev
The intent of invoking configfs_depend_item in commit 7474f52a82d51 ("tcm_qla2xxx: Perform configfs depend/undepend for base_tpg") was to prevent a physical Fibre Channel port removal when virtual (NPIV) ports announced through that physical port are active. The change does not work as expected: it makes enabled physical port dependent on target configfs subsystem (the port's parent), something the configfs guarantees anyway. Besides, scheduling work in a worker thread and waiting for the work's completion is not really a valid workaround for the requirement not to call configfs_depend_item from a configfs callback: the call occasionally deadlocks. Thus, removing configfs_depend_item calls does not break anything and fixes the deadlock problem.

Biao Huang says: ==================== add ethernet binding and modify ethernet driver for mt2712 changes in v3: resend this series base on the latest net-next tree. changes in v2 as comments from Sean: 1. fix typo. 2. use capital letters for RMII/MII/RGMII in driver and bindings. v1: This new series is the result of discussion in: http://lkml.org/lkml/2018/12/13/1007 http://lkml.org/lkml/2018/12/14/53 1. ethernet binding file move to this series. 2. remove fine tune property in device tree 3. remove fine tune flow in ethernet driver 4. set rgmii timing according to the value in device tree, and don't care whether phy insert internal delay or not. ==================== Signed-off-by: David S.

2018-12-19gro_cell: add napi_disable in gro_cells_destroyLorenzo Bianconi
Add napi_disable routine in gro_cells_destroy since starting from commit c42858eaf492 ("gro_cells: remove spinlock protecting receive queues") gro_cell_poll and gro_cells_destroy can run concurrently on napi_skbs list producing a kernel Oops if the tunnel interface is removed while gro_cell_poll is running.
