2020-04-13scsi: target: tcmu: reset_ring should reset TCMU_DEV_BIT_BROKENBodo Stroesser1-0/+1
In case command ring buffer becomes inconsistent, tcmu sets device flag TCMU_DEV_BIT_BROKEN. If the bit is set, tcmu rejects new commands from LIO core with TCM_LOGICAL_UNIT_COMMUNICATION_FAILURE, and no longer processes completions from the ring. The reset_ring attribute can be used to completely clean up the command ring, so after reset_ring the ring no longer is inconsistent. Therefore reset_ring also should reset bit TCMU_DEV_BIT_BROKEN to allow normal processing.

2020-04-13scsi: target: fix PR IN / READ FULL STATUS for FCBodo Stroesser1-1/+1
Creation of the response to READ FULL STATUS fails for FC based reservations. Reason is the too high loop limit (< 24) in fc_get_pr_transport_id(). The string representation of FC WWPN is 23 chars long only ("11:22:33:44:55:66:77:88"). So when i is 23, the loop body is executed a last time for the ending '\0' of the string and thus hex2bin() reports an error.

2020-04-13scsi: target: Write NULL to *port_nexus_ptr if no ISIDBodo Stroesser1-1/+2
This patch fixes a minor flaw that could be triggered by a PR OUT RESERVE on iSCSI, if TRANSPORT IDs with and without ISID are used in the same command. In case an ISCSI Transport ID has no ISID, port_nexus_ptr was not used to write NULL, so value from previous call might persist. I don't know if that ever could happen, but with the change the code is cleaner, I think.

2020-04-13opp: Manage empty OPP tables with clk handleRajendra Nayak1-0/+14
With OPP core now supporting DVFS for IO devices, we have instances of IO devices (same IP block) which require an OPP on some platforms/SoCs while just needing to scale the clock on some others. In order to avoid conditional code in every driver which supports such devices (to check for availability of OPPs and then deciding to do either dev_pm_opp_set_rate() or clk_set_rate()) add support to manage empty OPP tables with a clk handle. This makes dev_pm_opp_set_rate() equivalent of a clk_set_rate() for devices with just a clk and no OPPs specified, and makes dev_pm_opp_set_rate(0) bail out without throwing an error.

rbd_dev->opts is used to distinguish between the image that is being mapped and a parent. However, because we no longer establish watch for read-only mappings, this test is imprecise and results in unnecessary rbd_unregister_watch() calls.

2020-04-13rbd: call rbd_dev_unprobe() after unwatching and flushing notifiesIlya Dryomov1-4/+4
rbd_dev_unprobe() is supposed to undo most of rbd_dev_image_probe(), including rbd_dev_header_info(), which means that rbd_dev_header_info() isn't supposed to be called after rbd_dev_unprobe(). However, rbd_dev_image_release() calls rbd_dev_unprobe() before rbd_unregister_watch(). This is racy because a header update notify can sneak in: "rbd unmap" thread ceph-watch-notify worker rbd_dev_image_release() rbd_dev_unprobe() free and zero out header rbd_watch_cb() rbd_dev_refresh() rbd_dev_header_info() read in header The same goes for "rbd map" because rbd_dev_image_probe() calls rbd_dev_unprobe() on errors. In both cases this results in a memory leak.

2020-04-13rbd: avoid a deadlock on header_rwsem when flushing notifiesIlya Dryomov1-4/+13
rbd_unregister_watch() flushes notifies and therefore cannot be called under header_rwsem because a header update notify takes header_rwsem to synchronize with "rbd map". If mapping an image fails after the watch is established and a header update notify sneaks in, we deadlock when erroring out from rbd_dev_image_probe(). Move watch registration and unregistration out of the critical section. The only reason they were put there was to make header_rwsem management slightly more obvious.

The addition of the support for reading the temperature of ATA drives as per commit 5b46903d8bf3 ("hwmon: Driver for disk and solid state drives with temperature sensors") lists in the respective Kconfig section the name of the module to be optionally built as "satatemp". However, building the kernel modules with "CONFIG_SENSORS_DRIVETEMP=m", does not generate a file named "satatemp.ko". Instead, the rest of the original commit uses the term "drivetemp" and a file named "drivetemp.ko" ends up in the kernel's modules directory. This file has the right ingredients: $ strings /path/to/drivetemp.ko | grep ^description description=Hard drive temperature monitor and modprobing it produces the expected result: # drivetemp is not loaded $ sensors -u drivetemp-scsi-4-0 Specified sensor(s) not found! $ sudo modprobe drivetemp $ sensors -u drivetemp-scsi-4-0 drivetemp-scsi-4-0 Adapter: SCSI adapter temp1: temp1_input: 35.000 temp1_max: 60.000 temp1_min: 0.000 temp1_crit: 70.000 temp1_lcrit: -40.000 temp1_lowest: 20.000 temp1_highest: 36.000 Fix Kconfig by referring to the true name of the module.

The negotiation of flow control / pause frame modes was broken since commit fcf1f59afc67 ("net: phy: marvell: rearrange to use genphy_read_lpa()") moved the setting of phydev->duplex below the phy_resolve_aneg_pause call. Due to a check of DUPLEX_FULL in that function, phydev->pause was no longer set. Fix it by moving the parsing of the status variable before the blocks dealing with the pause frames. As the Marvell 88E1510 datasheet does not specify the timing between the link status and the "Speed and Duplex Resolved" bit, we have to force the link down as long as the resolved bit is not set, to avoid reporting link up before we even have valid Speed/Duplex.

2020-04-10x86/Hyper-V: Unload vmbus channel in hv panic callbackTianyu Lan2-8/+16
When kdump is not configured, a Hyper-V VM might still respond to network traffic after a kernel panic when kernel parameter panic=0. The panic CPU goes into an infinite loop with interrupts enabled, and the VMbus driver interrupt handler still works because the VMbus connection is unloaded only in the kdump path. The network responses make the other end of the connection think the VM is still functional even though it has panic'ed, which could affect any failover actions that should be taken. Fix this by unloading the VMbus connection during the panic process. vmbus_initiate_unload() could then be called twice (e.g., by hyperv_panic_event() and hv_crash_handler(), so reset the connection state in vmbus_initiate_unload() to ensure the unload is done only once.
