2020-03-26scsi: ufs: Enable block layer runtime PM for well-known logical unitsCan Guo
Block layer RPM is enabled for the genernal UFS SCSI devices when they are probed by their driver. However block layer RPM is not enabled for UFS well-known SCSI devices. As UFS SCSI devices have their corresponding BSG char devices, accessing a BSG char device via IOCTL may send requests to its corresponding SCSI device through its request queue. If BSG IOCTL sends a request to a well-known SCSI device when HBA is not runtime active, due to block layer RPM not being enabled for the well-known SCSI devices, the HBA, which is at the top of a SCSI device's parent chain, will not be resumed. This change enables block layer RPM for the well-known SCSI devices so that block layer can handle RPM for the well-known SCSI devices just like for the general SCSI devices.

2020-03-26Merge branch 'Implement-stats_update-callback-for-pedit-and-skbedit'David S. Miller
Petr Machata says: ==================== Implement stats_update callback for pedit and skbedit The stats_update callback is used for adding HW counters to the SW ones. Both skbedit and pedit actions are actually recognized by flow_offload.h, but do not implement these callbacks. As a consequence, the reported values are only the SW ones, even where there is a HW counter available. Patch #1 adds the callback to action skbedit, patch #2 adds it to action pedit. Patch #3 tweaks an skbedit selftest with a check that would have caught this problem. The pedit test is not likewise tweaked, because the iproute2 pedit action currently does not support JSON dumping. This will be addressed later. ==================== Signed-off-by: David S.

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.

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.

2020-03-26MAINTAINERS: fix bad file patternLinus Torvalds
Testing 'parse-maintainers' due to the previous commit shows a bad file pattern for the "TI VPE/CAL DRIVERS" entry in the MAINTAINERS file. There's also a lot of mis-ordered entries, but I'm still a bit nervous about the inevitable and annoying merge problems it would probably cause to fix them up. The MAINTAINERS file is one of my least favorite files due to being huge and centralized, but fixing it is also horribly painful for that reason.

2020-03-26parse-maintainers: Do not sort section content by defaultJoe Perches
Add an --order switch to control section reordering. Default for --order is off. Change the default ordering to a slightly more sensible: M: Person acting as a maintainer R: Person acting as a patch reviewer L: Mailing list where patches should be sent S: Maintenance status W: URI for general information Q: URI for patchwork tracking B: URI for bug tracking/submission C: URI for chat P: URI or file for subsystem specific coding styles T: SCM tree type and location F: File and directory pattern X: File and directory exclusion pattern N: File glob K: Keyword - patch content regex Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2020-03-26selftests: enforce local header dependency in lib.mkShuah Khan
Add local header dependency in lib.mk. This enforces the dependency blindly even when a test doesn't include the file, with the benefit of a simpler common logic without requiring individual tests to have special rule for it.

2020-03-26selftests: Fix memfd to support relocatable build (O=objdir)Shuah Khan
Fix memfd to support relocatable build (O=objdir). This calls out source files necessary to build tests and simplfies the dependency enforcement. Tested the following: Note that cross-build for fuse_mnt has dependency on -lfuse. make all make clean make kselftest-install O=/arm64_build/ ARCH=arm64 HOSTCC=gcc \ CROSS_COMPILE=aarch64-linux-gnu- TARGETS=memfd Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
2020-03-26selftests: Fix seccomp to support relocatable build (O=objdir)Shuah Khan
Fix seccomp relocatable builds. This is a simple fix to use the right lib.mk variable TEST_GEN_PROGS. Local header dependency is addressed in a change to lib.mk as a framework change that enforces the dependency without requiring changes to individual tests. The following use-cases work with this change: In seccomp directory: make all and make clean From top level from main Makefile: make kselftest-install O=objdir ARCH=arm64 HOSTCC=gcc \ CROSS_COMPILE=aarch64-linux-gnu- TARGETS=seccomp Signed-off-by: Shuah Khan <skhan@linuxfoundation.org> Acked-by: Kees Cook <keescook@chromium.org> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
2020-03-26selftests/harness: Handle timeouts cleanlyKees Cook
When a selftest would timeout before, the program would just fall over and no accounting of failures would be reported (i.e. it would result in an incomplete TAP report). Instead, add an explicit SIGALRM handler to cleanly catch and report the timeout. Before: [==========] Running 2 tests from 2 test cases. [ RUN ] timeout.finish [ OK ] timeout.finish [ RUN ] timeout.too_long Alarm clock After: [==========] Running 2 tests from 2 test cases. [ RUN ] timeout.finish [ OK ] timeout.finish [ RUN ] timeout.too_long timeout.too_long: Test terminated by timeout [ FAIL ] timeout.too_long [==========] 1 / 2 tests passed.

2020-03-26selftests/harness: Move test child waiting logicKees Cook
In order to better handle timeout failures, rearrange the child waiting logic into a separate function. This is mostly a copy/paste with an indentation change. To handle pid tracking, a new field is added for the child pid. Also move the alarm() pairing into the function.
