2023-04-28Merge tag 'modules-6.4-rc1' of ↵Linus Torvalds1-10/+3
git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux Pull module updates from Luis Chamberlain: "The summary of the changes for this pull requests is: - Song Liu's new struct module_memory replacement - Nick Alcock's MODULE_LICENSE() removal for non-modules - My cleanups and enhancements to reduce the areas where we vmalloc module memory for duplicates, and the respective debug code which proves the remaining vmalloc pressure comes from userspace. Most of the changes have been in linux-next for quite some time except the minor fixes I made to check if a module was already loaded prior to allocating the final module memory with vmalloc and the respective debug code it introduces to help clarify the issue. Although the functional change is small it is rather safe as it can only *help* reduce vmalloc space for duplicates and is confirmed to fix a bootup issue with over 400 CPUs with KASAN enabled. I don't expect stable kernels to pick up that fix as the cleanups would have also had to have been picked up. Folks on larger CPU systems with modules will want to just upgrade if vmalloc space has been an issue on bootup. Given the size of this request, here's some more elaborate details: The functional change change in this pull request is the very first patch from Song Liu which replaces the 'struct module_layout' with a new 'struct module_memory'. The old data structure tried to put together all types of supported module memory types in one data structure, the new one abstracts the differences in memory types in a module to allow each one to provide their own set of details. This paves the way in the future so we can deal with them in a cleaner way. If you look at changes they also provide a nice cleanup of how we handle these different memory areas in a module. This change has been in linux-next since before the merge window opened for v6.3 so to provide more than a full kernel cycle of testing. It's a good thing as quite a bit of fixes have been found for it. Jason Baron then made dynamic debug a first class citizen module user by using module notifier callbacks to allocate / remove module specific dynamic debug information. Nick Alcock has done quite a bit of work cross-tree to remove module license tags from things which cannot possibly be module at my request so to: a) help him with his longer term tooling goals which require a deterministic evaluation if a piece a symbol code could ever be part of a module or not. But quite recently it is has been made clear that tooling is not the only one that would benefit. Disambiguating symbols also helps efforts such as live patching, kprobes and BPF, but for other reasons and R&D on this area is active with no clear solution in sight. b) help us inch closer to the now generally accepted long term goal of automating all the MODULE_LICENSE() tags from SPDX license tags In so far as a) is concerned, although module license tags are a no-op for non-modules, tools which would want create a mapping of possible modules can only rely on the module license tag after the commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"). Nick has been working on this *for years* and AFAICT I was the only one to suggest two alternatives to this approach for tooling. The complexity in one of my suggested approaches lies in that we'd need a possible-obj-m and a could-be-module which would check if the object being built is part of any kconfig build which could ever lead to it being part of a module, and if so define a new define -DPOSSIBLE_MODULE [0]. A more obvious yet theoretical approach I've suggested would be to have a tristate in kconfig imply the same new -DPOSSIBLE_MODULE as well but that means getting kconfig symbol names mapping to modules always, and I don't think that's the case today. I am not aware of Nick or anyone exploring either of these options. Quite recently Josh Poimboeuf has pointed out that live patching, kprobes and BPF would benefit from resolving some part of the disambiguation as well but for other reasons. The function granularity KASLR (fgkaslr) patches were mentioned but Joe Lawrence has clarified this effort has been dropped with no clear solution in sight [1]. In the meantime removing module license tags from code which could never be modules is welcomed for both objectives mentioned above. Some developers have also welcomed these changes as it has helped clarify when a module was never possible and they forgot to clean this up, and so you'll see quite a bit of Nick's patches in other pull requests for this merge window. I just picked up the stragglers after rc3. LWN has good coverage on the motivation behind this work [2] and the typical cross-tree issues he ran into along the way. The only concrete blocker issue he ran into was that we should not remove the MODULE_LICENSE() tags from files which have no SPDX tags yet, even if they can never be modules. Nick ended up giving up on his efforts due to having to do this vetting and backlash he ran into from folks who really did *not understand* the core of the issue nor were providing any alternative / guidance. I've gone through his changes and dropped the patches which dropped the module license tags where an SPDX license tag was missing, it only consisted of 11 drivers. To see if a pull request deals with a file which lacks SPDX tags you can just use: ./scripts/spdxcheck.py -f \ $(git diff --name-only commid-id | xargs echo) You'll see a core module file in this pull request for the above, but that's not related to his changes. WE just need to add the SPDX license tag for the kernel/module/kmod.c file in the future but it demonstrates the effectiveness of the script. Most of Nick's changes were spread out through different trees, and I just picked up the slack after rc3 for the last kernel was out. Those changes have been in linux-next for over two weeks. The cleanups, debug code I added and final fix I added for modules were motivated by David Hildenbrand's report of boot failing on a systems with over 400 CPUs when KASAN was enabled due to running out of virtual memory space. Although the functional change only consists of 3 lines in the patch "module: avoid allocation if module is already present and ready", proving that this was the best we can do on the modules side took quite a bit of effort and new debug code. The initial cleanups I did on the modules side of things has been in linux-next since around rc3 of the last kernel, the actual final fix for and debug code however have only been in linux-next for about a week or so but I think it is worth getting that code in for this merge window as it does help fix / prove / evaluate the issues reported with larger number of CPUs. Userspace is not yet fixed as it is taking a bit of time for folks to understand the crux of the issue and find a proper resolution. Worst come to worst, I have a kludge-of-concept [3] of how to make kernel_read*() calls for modules unique / converge them, but I'm currently inclined to just see if userspace can fix this instead" Link: https://lore.kernel.org/all/Y/kXDqW+7d71C4wz@bombadil.infradead.org/ [0] Link: https://lkml.kernel.org/r/025f2151-ce7c-5630-9b90-98742c97ac65@redhat.com [1] Link: https://lwn.net/Articles/927569/ [2] Link: https://lkml.kernel.org/r/20230414052840.1994456-3-mcgrof@kernel.org [3] * tag 'modules-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: (121 commits) module: add debugging auto-load duplicate module support module: stats: fix invalid_mod_bytes typo module: remove use of uninitialized variable len module: fix building stats for 32-bit targets module: stats: include uapi/linux/module.h module: avoid allocation if module is already present and ready module: add debug stats to help identify memory pressure module: extract patient module check into helper modules/kmod: replace implementation with a semaphore Change DEFINE_SEMAPHORE() to take a number argument module: fix kmemleak annotations for non init ELF sections module: Ignore L0 and rename is_arm_mapping_symbol() module: Move is_arm_mapping_symbol() to module_symbol.h module: Sync code of is_arm_mapping_symbol() scripts/gdb: use mem instead of core_layout to get the module address interconnect: remove module-related code interconnect: remove MODULE_LICENSE in non-modules zswap: remove MODULE_LICENSE in non-modules zpool: remove MODULE_LICENSE in non-modules x86/mm/dump_pagetables: remove MODULE_LICENSE in non-modules ...

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "Core: - Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the default value allows for better BIG TCP performances - Reduce compound page head access for zero-copy data transfers - RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when possible - Threaded NAPI improvements, adding defer skb free support and unneeded softirq avoidance - Address dst_entry reference count scalability issues, via false sharing avoidance and optimize refcount tracking - Add lockless accesses annotation to sk_err[_soft] - Optimize again the skb struct layout - Extends the skb drop reasons to make it usable by multiple subsystems - Better const qualifier awareness for socket casts BPF: - Add skb and XDP typed dynptrs which allow BPF programs for more ergonomic and less brittle iteration through data and variable-sized accesses - Add a new BPF netfilter program type and minimal support to hook BPF programs to netfilter hooks such as prerouting or forward - Add more precise memory usage reporting for all BPF map types - Adds support for using {FOU,GUE} encap with an ipip device operating in collect_md mode and add a set of BPF kfuncs for controlling encap params - Allow BPF programs to detect at load time whether a particular kfunc exists or not, and also add support for this in light skeleton - Bigger batch of BPF verifier improvements to prepare for upcoming BPF open-coded iterators allowing for less restrictive looping capabilities - Rework RCU enforcement in the verifier, add kptr_rcu and enforce BPF programs to NULL-check before passing such pointers into kfunc - Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and in local storage maps - Enable RCU semantics for task BPF kptrs and allow referenced kptr tasks to be stored in BPF maps - Add support for refcounted local kptrs to the verifier for allowing shared ownership, useful for adding a node to both the BPF list and rbtree - Add BPF verifier support for ST instructions in convert_ctx_access() which will help new -mcpu=v4 clang flag to start emitting them - Add ARM32 USDT support to libbpf - Improve bpftool's visual program dump which produces the control flow graph in a DOT format by adding C source inline annotations Protocols: - IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value indicates the provenance of the IP address - IPv6: optimize route lookup, dropping unneeded R/W lock acquisition - Add the handshake upcall mechanism, allowing the user-space to implement generic TLS handshake on kernel's behalf - Bridge: support per-{Port, VLAN} neighbor suppression, increasing resilience to nodes failures - SCTP: add support for Fair Capacity and Weighted Fair Queueing schedulers - MPTCP: delay first subflow allocation up to its first usage.

This is needed for BIT TCP support - The iptables 32bit compat interface isn't compiled in by default anymore - Move ip(6)tables builtin icmp matches to the udptcp one. This has the advantage that icmp/icmpv6 match doesn't load the iptables/ip6tables modules anymore when iptables-nft is used - Extended netlink error report for netdevice in flowtables and netdev/chains. Allow for incrementally add/delete devices to netdev basechain. Allow to create netdev chain without device Driver API: - Remove redundant Device Control Error Reporting Enable, as PCI core has already error reporting enabled at enumeration time - Move Multicast DB netlink handlers to core, allowing devices other then bridge to use them - Allow the page_pool to directly recycle the pages from safely localized NAPI - Implement lockless TX queue stop/wake combo macros, allowing for further code de-duplication and sanitization - Add YNL support for user headers and struct attrs - Add partial YNL specification for devlink - Add partial YNL specification for ethtool - Add tc-mqprio and tc-taprio support for preemptible traffic classes - Add tx push buf len param to ethtool, specifies the maximum number of bytes of a transmitted packet a driver can push directly to the underlying device - Add basic LED support for switch/phy - Add NAPI documentation, stop relaying on external links - Convert dsa_master_ioctl() to netdev notifier.

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 Sakamoto1-2/+3
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.

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.

2023-04-20net/handshake: Create a NETLINK service for handling handshake requestsChuck Lever1-0/+9
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>
