2020-03-26devlink: add function to take snapshot while lockedJacob Keller
A future change is going to add a new devlink command to request a snapshot on demand. This function will want to call the devlink_region_snapshot_create function while already holding the devlink instance lock. Extract the logic of this function into a static function prefixed by `__` to indicate that it is an internal helper function. Modify the original function to be implemented in terms of the new locked function.

2020-03-26devlink: trivial: fix tab in function documentationJacob Keller
The function documentation comment for devlink_region_snapshot_create included a literal tab character between 'future analyses' that was difficult to spot as it happened to only display as one space wide.

2020-03-26devlink: convert snapshot destructor callback to region opJacob Keller
It does not makes sense that two snapshots for a given region would use different destructors. Simplify snapshot creation by adding a .destructor op for regions. This operation will replace the data_destructor for the snapshot creation, and makes snapshot creation easier.

2020-03-26devlink: prepare to support region operationsJacob Keller
Modify the devlink region code in preparation for adding new operations on regions. Create a devlink_region_ops structure, and move the name pointer from within the devlink_region structure into the ops structure (similar to the devlink_health_reporter_ops). This prepares the regions to enable support of additional operations in the future such as requesting snapshots, or accessing the region directly without a snapshot. In order to re-use the constant strings in the mlx4 driver their declaration must be changed to 'const char * const' to ensure the compiler realizes that both the data and the pointer cannot change.

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.

Both skbedit and pedit actions are actually recognized by flow_offload.h, but do not implement these callbacks.

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: 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.

2020-03-26bpf: Factor out attach_type to prog_type mapping for attach/detachAndrii Nakryiko
Factor out logic mapping expected program attach type to program type and subsequent handling of program attach/detach. Also list out all supported cgroup BPF program types explicitly to prevent accidental bugs once more program types are added to a mapping. Do the same for prog_query API.

2020-03-26bpf: Factor out cgroup storages operationsAndrii Nakryiko
Refactor cgroup attach/detach code to abstract away common operations performed on all types of cgroup storages. This makes high-level logic more apparent, plus allows to reuse more code across multiple functions.

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.

2020-03-26selftests: 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>

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.
