git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timers and timekeeping updates from Thomas Gleixner: - Improve the VDSO build time checks to cover all dynamic relocations VDSO does not allow dynamic relocations, but the build time check is incomplete and fragile. It's based on architectures specifying the relocation types to search for and does not handle R_*_NONE relocation entries correctly. R_*_NONE relocations are injected by some GNU ld variants if they fail to determine the exact .rel[a]/dyn_size to cover trailing zeros. R_*_NONE relocations must be ignored by dynamic loaders, so they should be ignored in the build time check too. Remove the architecture specific relocation types to check for and validate strictly that no other relocations than R_*_NONE end up in the VSDO .so file. - Prefer signal delivery to the current thread for CLOCK_PROCESS_CPUTIME_ID based posix-timers Such timers prefer to deliver the signal to the main thread of a process even if the context in which the timer expires is the current task. This has the downside that it might wake up an idle thread. As there is no requirement or guarantee that the signal has to be delivered to the main thread, avoid this by preferring the current task if it is part of the thread group which shares sighand. This not only avoids waking idle threads, it also distributes the signal delivery in case of multiple timers firing in the context of different threads close to each other better. - Align the tick period properly (again) For a long time the tick was starting at CLOCK_MONOTONIC zero, which allowed users space applications to either align with the tick or to place a periodic computation so that it does not interfere with the tick. The alignement of the tick period was more by chance than by intention as the tick is set up before a high resolution clocksource is installed, i.e. timekeeping is still tick based and the tick period advances from there. The early enablement of sched_clock() broke this alignement as the time accumulated by sched_clock() is taken into account when timekeeping is initialized. So the base value now(CLOCK_MONOTONIC) is not longer a multiple of tick periods, which breaks applications which relied on that behaviour. Cure this by aligning the tick starting point to the next multiple of tick periods, i.e 1000ms/CONFIG_HZ. - A set of NOHZ fixes and enhancements: * Cure the concurrent writer race for idle and IO sleeptime statistics The statitic values which are exposed via /proc/stat are updated from the CPU local idle exit and remotely by cpufreq, but that happens without any form of serialization. As a consequence sleeptimes can be accounted twice or worse. Prevent this by restricting the accumulation writeback to the CPU local idle exit and let the remote access compute the accumulated value. * Protect idle/iowait sleep time with a sequence count Reading idle/iowait sleep time, e.g. from /proc/stat, can race with idle exit updates. As a consequence the readout may result in random and potentially going backwards values. Protect this by a sequence count, which fixes the idle time statistics issue, but cannot fix the iowait time problem because iowait time accounting races with remote wake ups decrementing the remote runqueues nr_iowait counter. The latter is impossible to fix, so the only way to deal with that is to document it properly and to remove the assertion in the selftest which triggers occasionally due to that. * Restructure struct tick_sched for better cache layout * Some small cleanups and a better cache layout for struct tick_sched - Implement the missing timer_wait_running() callback for POSIX CPU timers For unknown reason the introduction of the timer_wait_running() callback missed to fixup posix CPU timers, which went unnoticed for almost four years. While initially only targeted to prevent livelocks between a timer deletion and the timer expiry function on PREEMPT_RT enabled kernels, it turned out that fixing this for mainline is not as trivial as just implementing a stub similar to the hrtimer/timer callbacks. The reason is that for CONFIG_POSIX_CPU_TIMERS_TASK_WORK enabled systems there is a livelock issue independent of RT. CONFIG_POSIX_CPU_TIMERS_TASK_WORK=y moves the expiry of POSIX CPU timers out from hard interrupt context to task work, which is handled before returning to user space or to a VM. The expiry mechanism moves the expired timers to a stack local list head with sighand lock held. Once sighand is dropped the task can be preempted and a task which wants to delete a timer will spin-wait until the expiry task is scheduled back in. In the worst case this will end up in a livelock when the preempting task and the expiry task are pinned on the same CPU. The timer wheel has a timer_wait_running() mechanism for RT, which uses a per CPU timer-base expiry lock which is held by the expiry code and the task waiting for the timer function to complete blocks on that lock. This does not work in the same way for posix CPU timers as there is no timer base and expiry for process wide timers can run on any task belonging to that process, but the concept of waiting on an expiry lock can be used too in a slightly different way. Add a per task mutex to struct posix_cputimers_work, let the expiry task hold it accross the expiry function and let the deleting task which waits for the expiry to complete block on the mutex. In the non-contended case this results in an extra mutex_lock()/unlock() pair on both sides. This avoids spin-waiting on a task which is scheduled out, prevents the livelock and cures the problem for RT and !RT systems * tag 'timers-core-2023-04-24' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: posix-cpu-timers: Implement the missing timer_wait_running callback selftests/proc: Assert clock_gettime(CLOCK_BOOTTIME) VS /proc/uptime monotonicity selftests/proc: Remove idle time monotonicity assertions MAINTAINERS: Remove stale email address timers/nohz: Remove middle-function __tick_nohz_idle_stop_tick() timers/nohz: Add a comment about broken iowait counter update race timers/nohz: Protect idle/iowait sleep time under seqcount timers/nohz: Only ever update sleeptime from idle exit timers/nohz: Restructure and reshuffle struct tick_sched tick/common: Align tick period with the HZ tick. selftests/timers/posix_timers: Test delivery of signals across threads posix-timers: Prefer delivery of signals to the current thread vdso: Improve cmd_vdso_check to check all dynamic relocations

git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull user work thread updates from Christian Brauner: "This contains the work generalizing the ability to create a kernel worker from a userspace process. Such user workers will run with the same credentials as the userspace process they were created from providing stronger security and accounting guarantees than the traditional override_creds() approach ever could've hoped for. The original work was heavily based and optimzed for the needs of io_uring which was the first user. However, as it quickly turned out the ability to create user workers inherting properties from a userspace process is generally useful. The vhost subsystem currently creates workers using the kthread api. The consequences of using the kthread api are that RLIMITs don't work correctly as they are inherited from khtreadd. This leads to bugs where more workers are created than would be allowed by the RLIMITs of the userspace process in lieu of which workers are created. Problems like this disappear with user workers created from the userspace processes for which they perform the work. In addition, providing this api allows vhost to remove additional complexity. For example, cgroup and mm sharing will just work out of the box with user workers based on the relevant userspace process instead of manually ensuring the correct cgroup and mm contexts are used. So the vhost subsystem should simply be made to use the same mechanism as io_uring. To this end the original mechanism used for create_io_thread() is generalized into user workers: - Introduce PF_USER_WORKER as a generic indicator that a given task is a user worker, i.e., a kernel task that was created from a userspace process. Now a PF_IO_WORKER thread is just a specialized version of PF_USER_WORKER. So io_uring io workers raise both flags. - Make copy_process() available to core kernel code - Extend struct kernel_clone_args with the following bitfields allowing to indicate to copy_process(): - to create a user worker (raise PF_USER_WORKER) - to not inherit any files from the userspace process - to ignore signals After all generic changes are in place the vhost subsystem implements a new dedicated vhost api based on user workers. Finally, vhost is switched to rely on the new api moving it off of kthreads.

git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux Pull selinux updates from Paul Moore: - Stop passing the 'selinux_state' pointers as function arguments As discussed during the end of the last development cycle, passing a selinux_state pointer through the SELinux code has a noticeable impact on performance, and with the current code it is not strictly necessary. This simplifies things by referring directly to the single selinux_state global variable which should help improve SELinux performance. - Uninline the unlikely portions of avc_has_perm_noaudit() This change was also based on a discussion from the last development cycle, and is heavily based on an initial proof of concept patch from you. The core issue was that avc_has_perm_noaudit() was not able to be inlined, as intended, due to its size. We solved this issue by extracting the less frequently hit portions of avc_has_perm_noaudit() into a separate function, reducing the size of avc_has_perm_noaudit() to the point where the compiler began inlining the function. We also took the opportunity to clean up some ugly RCU locking in the code that became uglier with the change. - Remove the runtime disable functionality After several years of work by the userspace and distro folks, we are finally in a place where we feel comfortable removing the runtime disable functionality which we initially deprecated at the start of 2020. There is plenty of information in the kernel's deprecation (now removal) notice, but the main motivation was to be able to safely mark the LSM hook structures as '__ro_after_init'. LWN also wrote a good summary of the deprecation this morning which offers a more detailed history: https://lwn.net/SubscriberLink/927463/dcfa0d4ed2872f03 - Remove the checkreqprot functionality The original checkreqprot deprecation notice stated that the removal would happen no sooner than June 2021, which means this falls hard into the "better late than never" bucket. The Kconfig and deprecation notice has more detail on this setting, but the basic idea is that we want to ensure that the SELinux policy allows for the memory protections actually applied by the kernel, and not those requested by the process. While we haven't found anyone running a supported distro that is affected by this deprecation/removal, anyone who is affected would only need to update their policy to reflect the reality of their applications' mapping protections. - Minor Makefile improvements Some minor Makefile improvements to correct some dependency issues likely only ever seen by SELinux developers. I expect we will have at least one more tweak to the Makefile during the next merge window, but it didn't quite make the cutoff this time around. * tag 'selinux-pr-20230420' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: ensure av_permissions.h is built when needed selinux: fix Makefile dependencies of flask.h selinux: stop returning node from avc_insert() selinux: clean up dead code after removing runtime disable selinux: update the file list in MAINTAINERS selinux: remove the runtime disable functionality selinux: remove the 'checkreqprot' functionality selinux: stop passing selinux_state pointers and their offspring selinux: uninline unlikely parts of avc_has_perm_noaudit()

This adds a driver based on serdev driver for the NXP BT serial protocol based on running H:4, which can enable the built-in Bluetooth device inside an NXP BT chip. This driver has Power Save feature that will put the chip into sleep state whenever there is no activity for 2000ms, and will be woken up when any activity is to be initiated over UART. This driver enables the power save feature by default by sending the vendor specific commands to the chip during setup. During setup, the driver checks if a FW is already running on the chip by waiting for the bootloader signature, and downloads device specific FW file into the chip over UART if bootloader signature is received..

2023-04-24MAINTAINERS: replace maintainer of FireWire subsystemTakashi Sakamoto
In the last few years, I have reviewed patches for FireWire subsystem and requested sound subsystem maintainer to sent them to mainline, since FireWire subsystem maintainer has been long absent. This situation is not preferable since we have some user of sound hardware in IEEE 1394 bus. I will stand for the maintainer, and work for FireWire core functions and 1394 OHCI driver, as well as sound drivers. This commit replaces the corresponding entry. As you know, IEEE 1394 is enough legacy. I would like to schedule the end of my work in the subsystem. My effort will last next 6 years. In 2026, I will start strong announcement for users to migrate their work load from IEEE 1394 bus (e.g. by purchasing alternative devices in USB and hardening system for them), then in 2029 let me resign the maintainer and close Linux 1394 project. My current work focuses on real time data (sampling data) transmission protocol in packet-oriented communication, thus I would provide less help to implementations for the other type of protocol; i.e. IPv4/IPv6 over IEEE 1394 bus (firewire-net), SCSI transport protocol over IEEE 1394 bus (firewire-sbp2) and iSCSI target (sbp-target). If receiving few objections from developers, I will start my work to send fixes for v6.3 prepatch, and PR for future v6.4 or later. I'm pleased if getting any help until the end.

In the old days where each device had a custom kernel, the android config fragments were useful to provide the required and reccomended options expected by userland. However, these days devices are expected to use the GKI kernel, so these config fragments no longer needed, and out of date, so they seem to only cause confusion. So lets drop them.

2023-04-19net/handshake: Create a NETLINK service for handling handshake requestsChuck Lever
When a kernel consumer needs a transport layer security session, it first needs a handshake to negotiate and establish a session. This negotiation can be done in user space via one of the several existing library implementations, or it can be done in the kernel. No in-kernel handshake implementations yet exist. In their absence, we add a netlink service that can: a. Notify a user space daemon that a handshake is needed. b. Once notified, the daemon calls the kernel back via this netlink service to get the handshake parameters, including an open socket on which to establish the session. c. Once the handshake is complete, the daemon reports the session status and other information via a second netlink operation. This operation marks that it is safe for the kernel to use the open socket and the security session established there. The notification service uses a multicast group. Each handshake mechanism (eg, tlshd) adopts its own group number so that the handshake services are completely independent of one another. The kernel can then tell via netlink_has_listeners() whether a handshake service is active and prepared to handle a handshake request. A new netlink operation, ACCEPT, acts like accept(2) in that it instantiates a file descriptor in the user space daemon's fd table. If this operation is successful, the reply carries the fd number, which can be treated as an open and ready file descriptor. While user space is performing the handshake, the kernel keeps its muddy paws off the open socket. A second new netlink operation, DONE, indicates that the user space daemon is finished with the socket and it is safe for the kernel to use again. The operation also indicates whether a session was established successfully. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-04-16media: nxp: Add i.MX8 ISI driverLaurent Pinchart
The Image Sensing Interface (ISI) combines image processing pipelines with DMA engines to process and capture frames originating from a variety of sources. The inputs to the ISI go through Pixel Link interfaces, and their number and nature is SoC-dependent. They cover both capture interfaces (MIPI CSI-2 RX, HDMI RX) and memory inputs.
