2020-03-26scsi: ufs: fix uninitialized tx_lanes in ufshcd_disable_tx_lcc()Stanley Chu
In ufshcd_disable_tx_lcc(), if ufshcd_dme_get() or ufshcd_dme_peer_get() get fail, uninitialized variable "tx_lanes" may be used as unexpected lane ID for DME configuration. Fix this issue by initializing "tx_lanes".

2020-03-26scsi: iscsi: Report connection state in sysfsGabriel Krisman Bertazi
If an iSCSI connection happens to fail while the daemon isn't running (due to a crash or for another reason), the kernel failure report is not received. When the daemon restarts, there is insufficient kernel state in sysfs for it to know that this happened. open-iscsi tries to reopen every connection, but on different initiators, we'd like to know which connections have failed. There is session->state, but that has a different lifetime than an iSCSI connection, so it doesn't directly reflect the connection state.

2020-03-26scsi: target: core: add task tag to trace eventsViacheslav Dubeyko
Trace events target_sequencer_start and target_cmd_complete (include/trace/events/target.h) are ready to show NAA identifier, LUN ID, and many other important command details in the system log: TP_printk("%s -> LUN %03u %s data_length %6u CDB %s (TA:%s C:%02x)", However, it's still hard to identify command on the initiator and command on the target in the real life output of system log. For that purpose SCSI provides a command identifier or task tag (term used in previous standards). This patch adds tag ID in the system log's output: TP_printk("%s -> LUN %03u tag %#llx %s data_length %6u CDB %s (TA:%s C:%02x)", kworker/1:1-35 [001] .... 1392.989452: target_sequencer_start: naa.5001405ec1ba6364 -> LUN 001 tag 0x1 SERVICE_ACTION_IN_16 data_length 32 CDB 9e 10 00 00 00 00 00 00 00 00 00 00 00 20 00 00 (TA:SIMPLE C:00) kworker/1:1-35 [001] .... 1392.989456: target_cmd_complete: naa.5001405ec1ba6364 <- LUN 001 tag 0x1 status GOOD (sense len 0) SERVICE_ACTION_IN_16 data_length 32 CDB 9e 10 00 00 00 00 00 00 00 00 00 00 00 20 00 00 (TA:SIMPLE C:00) Link: https://lore.kernel.org/r/226e01deaa9baf46d6ff3b8698bc9fe881f7dfc1.camel@dubeyko.com Reviewed-by: Roman Bolshakov <r.bolshakov@yadro.com> Reviewed-by: Konstantin Shelekhin <k.shelekhin@yadro.com> Reviewed-by: Bart van Assche <bvanassche@acm.org> Signed-off-by: Viacheslav Dubeyko <v.dubeiko@yadro.com> Signed-off-by: Martin K.

2020-03-26scsi: target: iscsi: calling iscsit_stop_session() inside ↵Maurizio Lombardi
iscsit_close_session() has no effect iscsit_close_session() can only be called when nconn is zero (otherwise a kernel panic is triggered). If nconn is zero then iscsit_stop_session() does nothing and exits, so calling it makes no sense. We still need to call iscsit_check_session_usage_count() because this function will sleep if the session's refcount is not zero and we don't want to destroy the session structure if it's still being referenced.

2020-03-26scsi: target: fix hang when multiple threads try to destroy the same iscsi ↵Maurizio Lombardi
session A number of hangs have been reported against the target driver; they are due to the fact that multiple threads may try to destroy the iscsi session at the same time. This may be reproduced for example when a "targetcli iscsi/iqn.../tpg1 disable" command is executed while a logout operation is underway. When this happens, two or more threads may end up sleeping and waiting for iscsit_close_connection() to execute "complete(session_wait_comp)". Only one of the threads will wake up and proceed to destroy the session structure, the remaining threads will hang forever. Note that if the blocked threads are somehow forced to wake up with complete_all(), they will try to free the same iscsi session structure destroyed by the first thread, causing double frees, memory corruptions etc... With this patch, the threads that want to destroy the iscsi session will increase the session refcount and will set the "session_close" flag to 1; then they wait for the driver to close the remaining active connections. When the last connection is closed, iscsit_close_connection() will wake up all the threads and will wait for the session's refcount to reach zero; when this happens, iscsit_close_connection() will destroy the session structure because no one is referencing it anymore.

2020-03-26afs: Fix unpinned address list during probingDavid Howells
When it's probing all of a fileserver's interfaces to find which one is best to use, afs_do_probe_fileserver() takes a lock on the server record and notes the pointer to the address list. It doesn't, however, pin the address list, so as soon as it drops the lock, there's nothing to stop the address list from being freed under us. Fix this by taking a ref on the address list inside the locked section and dropping it at the end of the function.

2020-03-26IB/iser: Always check sig MR before putting it to the free poolSergey Gorenko
libiscsi calls the check_protection transport handler only if SCSI-Respose is received. So, the handler is never called if iSCSI task is completed for some other reason like a timeout or error handling. And this behavior looks correct. But the iSER does not handle this case properly because it puts a non-checked signature MR to the free pool. Then the error occurs at reusing the MR because it is not allowed to invalidate a signature MR without checking. This commit adds an extra check to iser_unreg_mem_fastreg(), which is a part of the task cleanup flow. Now the signature MR is checked there if it is needed.

2020-03-26RDMA/rxe: Set sys_image_guid to be aligned with HW IB devicesZhu Yanjun
The RXE driver doesn't set sys_image_guid and user space applications see zeros. This causes to pyverbs tests to fail with the following traceback, because the IBTA spec requires to have valid sys_image_guid. Traceback (most recent call last): File "./tests/test_device.py", line 51, in test_query_device self.verify_device_attr(attr) File "./tests/test_device.py", line 74, in verify_device_attr assert attr.sys_image_guid != 0 In order to fix it, set sys_image_guid to be equal to node_guid.

2020-03-26RISC-V: Only select essential drivers for SOC_VIRT configAnup Patel
The kconfig select causes build failues for SOC_VIRT config becaus we are selecting lot of VIRTIO drivers without selecting all required dependencies. Better approach is to only select essential drivers from SOC_VIRT config option and enable required VIRTIO drivers using defconfigs.

2020-03-26cpufreq: intel_pstate: Simplify intel_pstate_cpu_init()Rafael J. Wysocki
The initial policy value set by intel_pstate_cpu_init() depends on whether or not CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is set, but that is not necessary, because the core will set the policy to "performance" in cpufreq_init_policy() if the default governor is "performance" anyway. Accordingly, change intel_pstate_cpu_init() to always set policy to CPUFREQ_POLICY_POWERSAVE initially to provide a valid fallback value to cpufreq_init_policy() in case the default cpufreq governor is neither "powersave" nor "performance".

from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>: When two (or more) amplifiers are on the same link, the integrator may: a) assign dedicated slots for each of the amplifiers. b) provide the same configuration to all amplifiers, and rely on additional controls/processing in the amplifier to generate different outputs. case a) was the initial direction for SoundWire and is required for amplifiers with limited capabilities, but to deal with orientation or 'posture' changes it's easier to implement case b) when the amplifier can deal with multiple channels. This patchset suggest the use of the set_tdm_slot() API to define which of the channels will be consumed by what amplifiers. This maps well with SoundWire's 'ChannelEnable' registers. The notion of slot_width is however irrelevant here and ignored, and SoundWire ports are typically single direction, so only one of the two masks shall be used.
