Internally used portconfig array for storing port bandwidth params starts from offset zero. However port zero is not really used and we also copy the bus parameters to offset zero. So basically we endup with a code which has to subtract 1 from port number to get to port parameters. This is bit confusing to the reader so, make this bit more obvious by only copying the parameters to offset 1 instead of zero. This will avoid doing -1 every time when we try to get port params. Similar thing has been recently done with din/dout_port_mask. Signed-off-by:

currently the internal bitmask used for allocating ports starts with offset 0. This is bit confusing as data port numbers on Qualcomm controller are valid from 1 to 14. So adjust this bit mask accordingly, this will also help while adding static port map support. Signed-off-by:

Some of the SoundWire device ports are statically mapped to Controller ports during design, however there is no way to expose this information to the controller. Controllers like Qualcomm ones use this info to setup static bandwidth parameters for those ports. A generic port allocation is not possible in this cases! So this patch adds a new member m_port_map to struct sdw_slave to expose this static map. Signed-off-by:

For each device, the nosy driver allocates a pcilynx structure. A use-after-free might happen in the following scenario: 1. Open nosy device for the first time and call ioctl with command NOSY_IOC_START, then a new client A will be malloced and added to doubly linked list. 2. Open nosy device for the second time and call ioctl with command NOSY_IOC_START, then a new client B will be malloced and added to doubly linked list. 3. Call ioctl with command NOSY_IOC_START for client A, then client A will be readded to the doubly linked list. Now the doubly linked list is messed up. 4. Close the first nosy device and nosy_release will be called. In nosy_release, client A will be unlinked and freed. 5. Close the second nosy device, and client A will be referenced, resulting in UAF. The root cause of this bug is that the element in the doubly linked list is reentered into the list. Fix this bug by adding a check before inserting a client. If a client is already in the linked list, don't insert it.

Pull io_uring fixes from Jens Axboe: "Nothing really major in here, and finally nothing really related to signals. A few minor fixups related to the threading changes, and some general fixes, that's it. There's the pending gdb-get-confused-about-arch, but that's more of a cosmetic issue, nothing that hinder use of it. And given that other archs will likely be affected by that oddity too, better to postpone any changes there until 5.13 imho" * tag 'io_uring-5.12-2021-04-02' of git://git.kernel.dk/linux-block: io_uring: move reissue into regular IO path io_uring: fix EIOCBQUEUED iter revert io_uring/io-wq: protect against sprintf overflow io_uring: don't mark S_ISBLK async work as unbounded io_uring: drop sqd lock before handling signals for SQPOLL io_uring: handle setup-failed ctx in kill_timeouts io_uring: always go for cancellation spin on exec

Pull ACPI fixes from Rafael Wysocki: "These fix an ACPI tables management issue, an issue related to the ACPI enumeration of devices and CPU wakeup in the ACPI processor driver. Specifics: - Ensure that the memory occupied by ACPI tables on x86 will always be reserved to prevent it from being allocated for other purposes which was possible in some cases (Rafael Wysocki). - Fix the ACPI device enumeration code to prevent it from attempting to evaluate the _STA control method for devices with unmet dependencies which is likely to fail (Hans de Goede). - Fix the handling of CPU0 wakeup in the ACPI processor driver to prevent CPU0 online failures from occurring (Vitaly Kuznetsov)" * tag 'acpi-5.12-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: processor: Fix CPU0 wakeup in acpi_idle_play_dead() ACPI: scan: Fix _STA getting called on devices with unmet dependencies ACPI: tables: x86: Reserve memory occupied by ACPI tables
