sched/fair: Prevent dead task groups from regaining cfs_rq's
Kevin is reporting crashes which point to a use-after-free of a cfs_rq in update_blocked_averages(). Initial debugging revealed that we've live cfs_rq's (on_list=1) in an about to be kfree()'d task group in free_fair_sched_group(). However, it was unclear how that can happen. His kernel config happened to lead to a layout of struct sched_entity that put the 'my_q' member directly into the middle of the object which makes it incidentally overlap with SLUB's freelist pointer. That, in combination with SLAB_FREELIST_HARDENED's freelist pointer mangling, leads to a reliable access violation in form of a #GP which made the UAF fail fast. Michal seems to have run into the same issue[1]. He already correctly diagnosed that commit |

sched/core: Mitigate race cpus_share_cache()/update_top_cache_domain()
Nothing protects the access to the per_cpu variable sd_llc_id. When testing
the same CPU (i.e. this_cpu == that_cpu), a race condition exists with
update_top_cache_domain(). One scenario being:
CPU1 CPU2
==================================================================
per_cpu(sd_llc_id, CPUX) => 0
partition_sched_domains_locked()
detach_destroy_domains()
cpus_share_cache(CPUX, CPUX) update_top_cache_domain(CPUX)
per_cpu(sd_llc_id, CPUX) => 0
per_cpu(sd_llc_id, CPUX) = CPUX
per_cpu(sd_llc_id, CPUX) => CPUX
return false
ttwu_queue_cond() wouldn't catch smp_processor_id() == cpu and the result
is a warning triggered from ttwu_queue_wakelist().
Avoid a such race in cpus_share_cache() by always returning true when
this_cpu == that_cpu.
Fixes:

Pull exit cleanups from Eric Biederman: "While looking at some issues related to the exit path in the kernel I found several instances where the code is not using the existing abstractions properly. This set of changes introduces force_fatal_sig a way of sending a signal and not allowing it to be caught, and corrects the misuse of the existing abstractions that I found. A lot of the misuse of the existing abstractions are silly things such as doing something after calling a no return function, rolling BUG by hand, doing more work than necessary to terminate a kernel thread, or calling do_exit(SIGKILL) instead of calling force_sig(SIGKILL). In the review a deficiency in force_fatal_sig and force_sig_seccomp where ptrace or sigaction could prevent the delivery of the signal was found. I have added a change that adds SA_IMMUTABLE to change that makes it impossible to interrupt the delivery of those signals, and allows backporting to fix force_sig_seccomp And Arnd found an issue where a function passed to kthread_run had the wrong prototype, and after my cleanup was failing to build." * 'exit-cleanups-for-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (23 commits) soc: ti: fix wkup_m3_rproc_boot_thread return type signal: Add SA_IMMUTABLE to ensure forced siganls do not get changed signal: Replace force_sigsegv(SIGSEGV) with force_fatal_sig(SIGSEGV) exit/r8188eu: Replace the macro thread_exit with a simple return 0 exit/rtl8712: Replace the macro thread_exit with a simple return 0 exit/rtl8723bs: Replace the macro thread_exit with a simple return 0 signal/x86: In emulate_vsyscall force a signal instead of calling do_exit signal/sparc32: In setup_rt_frame and setup_fram use force_fatal_sig signal/sparc32: Exit with a fatal signal when try_to_clear_window_buffer fails exit/syscall_user_dispatch: Send ordinary signals on failure signal: Implement force_fatal_sig exit/kthread: Have kernel threads return instead of calling do_exit signal/s390: Use force_sigsegv in default_trap_handler signal/vm86_32: Properly send SIGSEGV when the vm86 state cannot be saved. signal/vm86_32: Replace open coded BUG_ON with an actual BUG_ON signal/sparc: In setup_tsb_params convert open coded BUG into BUG signal/powerpc: On swapcontext failure force SIGSEGV signal/sh: Use force_sig(SIGKILL) instead of do_group_exit(SIGKILL) signal/mips: Update (_save|_restore)_fp_context to fail with -EFAULT signal/sparc32: Remove unreachable do_exit in do_sparc_fault ... |

In order to activate core scheduling the caller is expected to specify the scope of the new core scheduling domain. For example, passing 2 in the 4th argument of prctl(PR_SCHED_CORE, PR_SCHED_CORE_CREATE, <pid>, 2, 0); would indicate that the new core scheduling domain encompasses all tasks in the process group of <pid>. Specifying 0 would only create a core scheduling domain for the thread identified by <pid> and 2 would encompass the whole thread-group of <pid>. Note, the values 0, 1, and 2 correspond to PIDTYPE_PID, PIDTYPE_TGID, and PIDTYPE_PGID. A first version tried to expose those values directly to which I objected because: - PIDTYPE_* is an enum that is kernel internal which we should not expose to userspace directly. - PIDTYPE_* indicates what a given struct pid is used for it doesn't express a scope. But what the 4th argument of PR_SCHED_CORE prctl() expresses is the scope of the operation, i.e. the scope of the core scheduling domain at creation time. So Eugene's patch now simply introduces three new defines PR_SCHED_CORE_SCOPE_THREAD, PR_SCHED_CORE_SCOPE_THREAD_GROUP, and PR_SCHED_CORE_SCOPE_PROCESS_GROUP. They simply express what happens. This has been on the mailing list for quite a while with all relevant scheduler folks Cced. I announced multiple times that I'd pick this up if I don't see or her anyone else doing it. None of this touches proper scheduler code but only concerns uapi so I think this is fine. With core scheduling being quite common now for vm managers (e.g. moving individual vcpu threads into their own core scheduling domain) and container managers (e.g. moving the init process into its own core scheduling domain and letting all created children inherit it) having to rely on raw numbers passed as the 4th argument in prctl() is a bit annoying and everyone is starting to come up with their own defines" * tag 'kernel.sys.v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: uapi/linux/prctl: provide macro definitions for the PR_SCHED_CORE type argument |

The two most recent additions have probably been the ability to use pidfds in bpf maps and the usage of pidfds in mm-based syscalls such as process_mrelease() and process_madvise(). The same pattern to turn a pidfd into a struct task exists in two places. One of those places used PIDTYPE_TGID while the other one used PIDTYPE_PID even though it is clearly documented in all pidfd-helpers that pidfds __currently__ only refer to thread-group leaders (subject to change in the future if need be). This isn't a bug per se but has the potential to be one if we allow pidfds to refer to individual threads. If that happens we want to audit all codepaths that make use of them to ensure they can deal with pidfds refering to individual threads. This adds a simple helper to turn a pidfd into a struct task making it easy to grep for such places. Plus, it gets rid of code-duplication" * tag 'pidfd.v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: mm: use pidfd_get_task() pid: add pidfd_get_task() helper |

remoteproc updates for v5.16
The remoteproc repo is moved to a new path on git.kernel.org, to allow Mathieu push access to the branches. Support for the Mediatek MT8195 SCP was added, the related DeviceTree binding was converted to YAML and MT8192 SCP was documented as well. Amlogic Meson6, Meson8, Meson8b and Meson8m2 has an ARC core to aid in resuming the system after suspend, a new remoteproc driver for booting this core is introduced. A new driver to support the DSP processor found on NXP i.MX8QM, i.MX8QXP, i.MX8MP and i.MX8ULP is added. The Qualcomm modem and TrustZone based remoteproc drivers gains support for the modem in SC7280 and MSM8996 gains support for a missing power-domain. Throughout the Qualcomm drivers, the support for informing the always-on power coprocessor about the state of each remoteproc is reworked to avoid complications related to our use of genpd and the system suspend state. Lastly a number of small fixes are found throughout the drivers and framework. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmGJYF8bHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3FIb0P/2Zw4zPf+sHIUaJs1QtD nI+EElRoC1pSj8jV2pqekBMLECenj/oR0uU0t+JXkyj/LStuJfTOcpnBrstTFXmO rpW2wdK+V7L8TRwVsRZKMCDxK0wX6GBvu47fMsNpy98t19JT66dytliHaauiKlYr QCuMKoY6nw0twuh4mtKKamA6XvjjbH8QdQK74vSrmIzgBskeCkvhBX3gRMEdev6m G8ZbusaauIrYnnf1s9uwkHT8HDZAtWw9qHI3xuzi9o+p2K+8YjPRDnOEZkHoVPo4 BfcLRGIX0DAmVdUBONANzQAXUhJHc/Y209ev4oKE6sAa2A8I2z1q3LLjOGa7cHaH a/RqdJWm8sHBqgalgVaN0dxLQ5ifv18dVW6kg905OjZJJma6I/W35wz+44o8UWG8 5rZEeAs2/zKiHPsxH0ss6zEBo7H8YtLHmU0Z08tSfZimokFkEWoqcHXYF3mSWL/M HUWQ4Kv51dWBDsZEeVLyiaTg6HX6ilK39RZC84dNEbKUY5PbndLfPpuP6Eg3HjFe z+NwTLG5nPlJExFPVvl3I2j3iEZRb24f8qMR5oDI6Qiq2CXZqEVrwt0zCLYHaejE 54rbtNH+8Rh8nn8MTV2hS+s3ORpFrNKxvTnNTZZp1kAhodoT23E57LyX/Nqqhn1+ A4pQRLLDn/QGQ9wWl5lCm5jl =i0ql -----END PGP SIGNATURE----- Merge tag 'rproc-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux Pull remoteproc updates from Bjorn Andersson: "The remoteproc repo is moved to a new path on git.kernel.org, to allow Mathieu push access to the branches.

rpmsg updates for v5.16
For the GLINK implementation this adds support for splitting outgoing messages that are too large to fit in the fifo, it introduces the use of "read notifications", to avoid polling in the case where the outgoing fifo is full and a few bugs are squashed. The return value of rpmsg_create_ept() for when RPMSG is disabled is corrected to return a valid error, the Mediatek rpmsg driver is updated to match the DT binding and a couple of cleanups are done in the virtio rpmsg driver. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmGJXMkbHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3F1tgP/RNK/m+bsWHDVRvMww1z SCC+E4b8vJIceifqvXataO5vMErFyQdTi9ijFNogqIlJF+ouVp/sHmfCCwFG4urw /IccreIcBWMoY8+efjomLVvCMEzd1RlSG484yKs4p8Jz7hDgGeDHzQOwe0CsTY/L b2Qi6fV6i1/sfK1vlf4dHFA7Y66KwjknvNCasCWkadBSJnJeali9QeRsDYaQCaJL C2QirxX7V2rxJZH248MOuG+E0e1oVgccvp9dACbsasfOrsekWc7Twizaqvdl+RxF q2YXH82WVClOQgyp09tZ8zk4IIVzzxKZlWL/so7sdiEI009HHNc7YhGkRUdzhzma neWPJ6emVUD4Gwgkr2OAkc14wR99iSgdjvN2CcZjOHgBKos2AvjN/JsrGLswVdDU PZs4EXzvgw98hOOTpw0X1E8TZvtt3wcUyoXpWop2+pXOs9rajR0lyorlW8ubXhLN TpC2Yypy8vY4kBn3Ob/sJlu5CNasMg3a4TFhJBCWIrmS+5MxwOtvAi+i4Omg6754 075zhFuxXuFdszWqtJHBukHpmhYkK1shexEnkLdPiCwpG2Q9159ILD2TKVIjAOQy 112o8KSCWcPR0VNoenTunqfw/YiOYmEeIGQBRfsxrFUurmPQMICN+xfei/8vQftg D9hxikFXc7JJl+OahXnvSUZv =jGA6 -----END PGP SIGNATURE----- Merge tag 'rpmsg-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux Pull rpmsg updates from Bjorn Andersson: "For the GLINK implementation this adds support for splitting outgoing messages that are too large to fit in the fifo, it introduces the use of "read notifications", to avoid polling in the case where the outgoing fifo is full and a few bugs are squashed.

selftests/kselftest/runner/run_one(): allow running non-executable files
When running a test program, 'run_one()' checks if the program has the execution permission and fails if it doesn't. However, it's easy to mistakenly lose the permissions, as some common tools like 'diff' don't support the permission change well[1]. Compared to that, making mistakes in the test program's path would only rare, as those are explicitly listed in 'TEST_PROGS'. Therefore, it might make more sense to resolve the situation on our own and run the program. For this reason, this commit makes the test program runner function still print the warning message but to try parsing the interpreter of the program and to explicitly run it with the interpreter, in this case.

virtio-mem: disallow mapping virtio-mem memory via /dev/mem
We don't want user space to be able to map virtio-mem device memory directly (e.g., via /dev/mem) in order to have guarantees that in a sane setup we'll never accidentially access unplugged memory within the device-managed region of a virtio-mem device, just as required by the virtio-spec. As soon as the virtio-mem driver is loaded, the device region is visible in /proc/iomem via the parent device region. From that point on user space is aware of the device region and we want to disallow mapping anything inside that region (where we will dynamically (un)plug memory) until the driver has been unloaded cleanly and e.g., another driver might take over. By creating our parent IORESOURCE_SYSTEM_RAM resource with IORESOURCE_EXCLUSIVE, we will disallow any /dev/mem access to our device region until the driver was unloaded cleanly and removed the parent region. This will work even though only some memory blocks are actually currently added to Linux and appear as busy in the resource tree. So access to the region from user space is only possible a) if we don't load the virtio-mem driver. b) after unloading the virtio-mem driver cleanly. Don't build virtio-mem if access to /dev/mem cannot be restricticted -- if we have CONFIG_DEVMEM=y but CONFIG_STRICT_DEVMEM is not set.

kernel/resource: disallow access to exclusive system RAM regions
virtio-mem dynamically exposes memory inside a device memory region as system RAM to Linux, coordinating with the hypervisor which parts are actually "plugged" and consequently usable/accessible. On the one hand, the virtio-mem driver adds/removes whole memory blocks, creating/removing busy IORESOURCE_SYSTEM_RAM resources, on the other hand, it logically (un)plugs memory inside added memory blocks, dynamically either exposing them to the buddy or hiding them from the buddy and marking them PG_offline. In contrast to physical devices, like a DIMM, the virtio-mem driver is required to actually make use of any of the device-provided memory, because it performs the handshake with the hypervisor. virtio-mem memory cannot simply be access via /dev/mem without a driver. There is no safe way to: a) Access plugged memory blocks via /dev/mem, as they might contain unplugged holes or might get silently unplugged by the virtio-mem driver and consequently turned inaccessible. b) Access unplugged memory blocks via /dev/mem because the virtio-mem driver is required to make them actually accessible first. The virtio-spec states that unplugged memory blocks MUST NOT be written, and only selected unplugged memory blocks MAY be read. We want to make sure, this is the case in sane environments -- where the virtio-mem driver was loaded. We want to make sure that in a sane environment, nobody "accidentially" accesses unplugged memory inside the device managed region. For example, a user might spot a memory region in /proc/iomem and try accessing it via /dev/mem via gdb or dumping it via something else. By the time the mmap() happens, the memory might already have been removed by the virtio-mem driver silently: the mmap() would succeeed and user space might accidentially access unplugged memory. So once the driver was loaded and detected the device along the device-managed region, we just want to disallow any access via /dev/mem to it. In an ideal world, we would mark the whole region as busy ("owned by a driver") and exclude it; however, that would be wrong, as we don't really have actual system RAM at these ranges added to Linux ("busy system RAM"). Instead, we want to mark such ranges as "not actual busy system RAM but still soft-reserved and prepared by a driver for future use." Let's teach iomem_is_exclusive() to reject access to any range with "IORESOURCE_SYSTEM_RAM | IORESOURCE_EXCLUSIVE", even if not busy and even if "iomem=relaxed" is set. Introduce EXCLUSIVE_SYSTEM_RAM to make it easier for applicable drivers to depend on this setting in their Kconfig. For now, there are no applicable ranges and we'll modify virtio-mem next to properly set IORESOURCE_EXCLUSIVE on the parent resource container it creates to contain all actual busy system RAM added via add_memory_driver_managed().

kernel/resource: clean up and optimize iomem_is_exclusive()
Patch series "virtio-mem: disallow mapping virtio-mem memory via /dev/mem", v5. Let's add the basic infrastructure to exclude some physical memory regions marked as "IORESOURCE_SYSTEM_RAM" completely from /dev/mem access, even though they are not marked IORESOURCE_BUSY and even though "iomem=relaxed" is set. Resource IORESOURCE_EXCLUSIVE for that purpose instead of adding new flags to express something similar to "soft-busy" or "not busy yet, but already prepared by a driver and not to be mapped by user space". Use it for virtio-mem, to disallow mapping any virtio-mem memory via /dev/mem to user space after the virtio-mem driver was loaded. This patch (of 3): We end up traversing subtrees of ranges we are not interested in; let's optimize this case, skipping such subtrees, cleaning up the function a bit. For example, in the following configuration (/proc/iomem): 00000000-00000fff : Reserved 00001000-00057fff : System RAM 00058000-00058fff : Reserved 00059000-0009cfff : System RAM 0009d000-000fffff : Reserved 000a0000-000bffff : PCI Bus 0000:00 000c0000-000c3fff : PCI Bus 0000:00 000c4000-000c7fff : PCI Bus 0000:00 000c8000-000cbfff : PCI Bus 0000:00 000cc000-000cffff : PCI Bus 0000:00 000d0000-000d3fff : PCI Bus 0000:00 000d4000-000d7fff : PCI Bus 0000:00 000d8000-000dbfff : PCI Bus 0000:00 000dc000-000dffff : PCI Bus 0000:00 000e0000-000e3fff : PCI Bus 0000:00 000e4000-000e7fff : PCI Bus 0000:00 000e8000-000ebfff : PCI Bus 0000:00 000ec000-000effff : PCI Bus 0000:00 000f0000-000fffff : PCI Bus 0000:00 000f0000-000fffff : System ROM 00100000-3fffffff : System RAM 40000000-403fffff : Reserved 40000000-403fffff : pnp 00:00 40400000-80a79fff : System RAM ... We don't have to look at any children of "0009d000-000fffff : Reserved" if we can just skip these 15 items directly because the parent range is not of interest.

kcov: replace local_irq_save() with a local_lock_t
The kcov code mixes local_irq_save() and spin_lock() in kcov_remote_{start|end}(). This creates a warning on PREEMPT_RT because local_irq_save() disables interrupts and spin_lock_t is turned into a sleeping lock which can not be acquired in a section with disabled interrupts. The kcov_remote_lock is used to synchronize the access to the hash-list kcov_remote_map. The local_irq_save() block protects access to the per-CPU data kcov_percpu_data. There is no compelling reason to change the lock type to raw_spin_lock_t to make it work with local_irq_save(). Changing it would require to move memory allocation (in kcov_remote_add()) and deallocation outside of the locked section. Adding an unlimited amount of entries to the hashlist will increase the IRQ-off time during lookup. It could be argued that this is debug code and the latency does not matter. There is however no need to do so and it would allow to use this facility in an RT enabled build. Using a local_lock_t instead of local_irq_save() has the befit of adding a protection scope within the source which makes it obvious what is protected. On a !PREEMPT_RT && !LOCKDEP build the local_lock_irqsave() maps directly to local_irq_save() so there is overhead at runtime. Replace the local_irq_save() section with a local_lock_t.

kcov: avoid enable+disable interrupts if !in_task()
kcov_remote_start() may need to allocate memory in the in_task() case (otherwise per-CPU memory has been pre-allocated) and therefore requires enabled interrupts. The interrupts are enabled before checking if the allocation is required so if no allocation is required then the interrupts are needlessly enabled and disabled again. Enable interrupts only if memory allocation is performed.
