2021-03-23USB: core: rename usb_driver_claim_interface() data parameterJohan Hovold
It's been almost twenty years since the interface "private data" pointer was removed in favour of using the driver-data pointer of struct device. Let's rename the driver-data parameter of usb_driver_claim_interface() so that it better reflects how it's used.

Commit 9fe61450972d ("namei: introduce struct renamedata") introduces a new struct for vfs_rename() and makes the vfs_rename() kernel-doc argument description out of sync.

2021-03-23fs: document and rename fsid helpersChristian Brauner
Vivek pointed out that the fs{g,u}id_into_mnt() naming scheme can be misleading as it could be understood as implying they do the exact same thing as i_{g,u}id_into_mnt(). The original motivation for this naming scheme was to signal to callers that the helpers will always take care to map the k{g,u}id such that the ownership is expressed in terms of the mnt_users. Get rid of the confusion by renaming those helpers to something more sensible. Al suggested mapped_fs{g,u}id() which seems a really good fit. Usually filesystems don't need to bother with these helpers directly only in some cases where they allocate objects that carry {g,u}ids which are either filesystem specific (e.g. xfs quota objects) or don't have a clean set of helpers as inodes have.

2021-03-22lsm: separate security_task_getsecid() into subjective and objective variantsPaul Moore
Of the three LSMs that implement the security_task_getsecid() LSM hook, all three LSMs provide the task's objective security credentials. This turns out to be unfortunate as most of the hook's callers seem to expect the task's subjective credentials, although a small handful of callers do correctly expect the objective credentials. This patch is the first step towards fixing the problem: it splits the existing security_task_getsecid() hook into two variants, one for the subjective creds, one for the objective creds. void security_task_getsecid_subj(struct task_struct *p, u32 *secid); void security_task_getsecid_obj(struct task_struct *p, u32 *secid); While this patch does fix all of the callers to use the correct variant, in order to keep this patch focused on the callers and to ease review, the LSMs continue to use the same implementation for both hooks. The net effect is that this patch should not change the behavior of the kernel in any way, it will be up to the latter LSM specific patches in this series to change the hook implementations and return the correct credentials.

2021-03-22dm table: Fix zoned model check and zone sectors checkShin'ichiro Kawasaki
Commit 24f6b6036c9e ("dm table: fix zoned iterate_devices based device capability checks") triggered dm table load failure when dm-zoned device is set up for zoned block devices and a regular device for cache. The commit inverted logic of two callback functions for iterate_devices: device_is_zoned_model() and device_matches_zone_sectors(). The logic of device_is_zoned_model() was inverted then all destination devices of all targets in dm table are required to have the expected zoned model. This is fine for dm-linear, dm-flakey and dm-crypt on zoned block devices since each target has only one destination device. However, this results in failure for dm-zoned with regular cache device since that target has both regular block device and zoned block devices. As for device_matches_zone_sectors(), the commit inverted the logic to require all zoned block devices in each target have the specified zone_sectors. This check also fails for regular block device which does not have zones. To avoid the check failures, fix the zone model check and the zone sectors check. For zone model check, introduce the new feature flag DM_TARGET_MIXED_ZONED_MODEL, and set it to dm-zoned target. When the target has this flag, allow it to have destination devices with any zoned model. For zone sectors check, skip the check if the destination device is not a zoned block device. Also add comments and improve an error message to clarify expectations to the two checks.

2021-03-22rcu: Provide polling interfaces for Tree RCU grace periodsPaul E. McKenney
There is a need for a non-blocking polling interface for RCU grace periods, so this commit supplies start_poll_synchronize_rcu() and poll_state_synchronize_rcu() for this purpose. Note that the existing get_state_synchronize_rcu() may be used if future grace periods are inevitable (perhaps due to a later call_rcu() invocation). The new start_poll_synchronize_rcu() is to be used if future grace periods might not otherwise happen. Finally, poll_state_synchronize_rcu() provides a lockless check for a grace period having elapsed since the corresponding call to either of the get_state_synchronize_rcu() or start_poll_synchronize_rcu(). As with get_state_synchronize_rcu(), the return value from either get_state_synchronize_rcu() or start_poll_synchronize_rcu() is passed in to a later call to either poll_state_synchronize_rcu() or the existing (might_sleep) cond_synchronize_rcu().

2021-03-22soundwire: add master quirks for bus clash and parityBard Liao
Currently quirks are only allowed for Slave devices. This patch describes the need for two quirks at the Master level. a) bus clash The SoundWire specification allows a Slave device to report a bus clash with the in-band interrupt mechanism when it detects a conflict while driving a bitSlot it owns. This can be a symptom of an electrical conflict or a programming error, and it's vital to detect reliably. Unfortunately, on some platforms, bus clashes are randomly reported by Slave devices after a bus reset, with an interrupt status set even before the bus clash interrupt is enabled. These initial spurious interrupts are not relevant and should optionally be filtered out, while leaving the interrupt mechanism enabled to detect 'true' issues. This patch suggests the addition of a Master level quirk to discard such interrupts. The quirk should in theory have been added at the Slave level, but since the problem was detected with different generations of Slave devices it's hard to point to a specific IP. The problem might also be board-dependent and hence dealing with a Master quirk is simpler. b) parity Additional tests on a new platform with the Maxim 98373 amplifier showed a rare case where the parity interrupt is also thrown on startup, at the same time as bus clashes. This issue only seems to happen infrequently and was only observed during suspend-resume stress tests while audio is streaming. We could make the problem go away by adding a Slave-level quirk, but there is no evidence that the issue is actually a Slave problem: the parity is provided by the Master, which could also set an invalid parity in corner cases.

2021-03-22media: uapi: move VP8 stateless controls out of stagingEzequiel Garcia
Until now, the VP8 V4L2 API was not exported as a public API, and only defined in a private media header (media/vp8-ctrls.h). The reason for this was a concern about the API not complete and ready to support VP8 decoding hardware accelerators. After reviewing the VP8 specification in detail, and now that the API is able to support Cedrus and Hantro G1, we can consider this ready.
