commit 19221e3 upstream. The tegra_powergate_power_up() has a typo in the error code path where it will try to disable clocks twice, fix it. In practice that error never happens, so this is a minor correction.

…EVEL commit a923a26 upstream.

This is due to MIPS_ISA_ARCH_LEVEL downgrading the assembly architecture to `r4000' i.e. MIPS III for MIPS64r2 configurations, while there is a block of code containing a DINS MIPS64r2 instruction conditionalized on MIPS_ISA_REV >= 2 within the scope of the downgrade. The assembly architecture override code pattern has been put there for LL/SC instructions, so that code compiles for configurations that select a processor to build for that does not support these instructions while still providing run-time support for processors that do, dynamically switched by non-constant `cpu_has_llsc'. It went in with linux-mips.org commit aac8aa7 ("Enable a suitable ISA for the assembler around ll/sc so that code builds even for processors that don't support the instructions. Plus minor formatting fixes.") back in 2005. Fix the problem by wrapping these instructions along with the adjacent SYNC instructions only, following the practice established with commit cfd54de ("MIPS: Avoid move psuedo-instruction whilst using MIPS_ISA_LEVEL") and commit 378ed6f ("MIPS: Avoid using .set mips0 to restore ISA"). Strictly speaking the SYNC instructions do not have to be wrapped as they are only used as a Loongson3 erratum workaround, so they will be enabled in the assembler by default, but do this so as to keep code consistent with other places.

commit eeb1b55 upstream. When non-fatal error like line-reset happens, ufshcd_err_handler() starts to abort tasks by ufshcd_try_to_abort_task().

commit a52f8a5 upstream. Clang has never correctly compiled the FORTIFY_SOURCE defenses due to a couple bugs: Eliding inlines with matching __builtin_* names https://bugs.llvm.org/show_bug.cgi?id=50322 Incorrect __builtin_constant_p() of some globals https://bugs.llvm.org/show_bug.cgi?id=41459 In the process of making improvements to the FORTIFY_SOURCE defenses, the first (silent) bug (coincidentally) becomes worked around, but exposes the latter which breaks the build. As such, Clang must not be used with CONFIG_FORTIFY_SOURCE until at least latter bug is fixed (in Clang 13), and the fortify routines have been rearranged.

commit 3ec18fc upstream. commit 8779e05 ("parisc: Fix ptrace check on syscall return") fixed testing of TI_FLAGS. This uncovered a bug in the test mask. syscall_restore_rfi is only used when the kernel needs to exit to usespace with single or block stepping and the recovery counter enabled. The test however used _TIF_SYSCALL_TRACE_MASK, which includes a lot of bits that shouldn't be tested here. Fix this by using TIF_SINGLESTEP and TIF_BLOCKSTEP directly. I encountered this bug by enabling syscall tracepoints. Both in qemu and on real hardware. As soon as i enabled the tracepoint (sys_exit_read, but i guess it doesn't really matter which one), i got random page faults in userspace almost immediately.

commit 86432a6 upstream. There are pclusters in runtime marked with Z_EROFS_PCLUSTER_TAIL before actual I/O submission. Thus, the decompression chain can be extended if the following pcluster chain hooks such tail pcluster. As the related comment mentioned, if some page is made of a hooked pcluster and another followed pcluster, it can be reused for in-place I/O (since I/O should be submitted anyway): _______________________________________________________________ | tail (partial) page | head (partial) page | |_____PRIMARY_HOOKED___|____________PRIMARY_FOLLOWED____________| However, it's by no means safe to reuse as pagevec since if such PRIMARY_HOOKED pclusters finally move into bypass chain without I/O submission. It's somewhat hard to reproduce with LZ4 and I just found it (general protection fault) by ro_fsstressing a LZMA image for long time. I'm going to actively clean up related code together with multi-page folio adaption in the next few months. Let's address it directly for easier backporting for now.

[ Upstream commit 9915458 ] When parsing the txq list in lpfc_drain_txq(), the driver attempts to pass the requests to the adapter. If such an attempt fails, a local "fail_msg" string is set and a log message output. The job is then added to a completions list for cancellation. Processing of any further jobs from the txq list continues, but since "fail_msg" remains set, jobs are added to the completions list regardless of whether a wqe was passed to the adapter. If successfully added to txcmplq, jobs are added to both lists resulting in list corruption. Fix by clearing the fail_msg string after adding a job to the completions list. This stops the subsequent jobs from being added to the completions list unless they had an appropriate failure.

[ Upstream commit 3f1dcaf ] The entry/exit latency and minimum residency in state for the idle states of MSM8998 were ..bad: first of all, for all of them the timings were written for CPU sleep but the min-residency-us param was miscalculated (supposedly, while porting this from downstream); Then, the power collapse states are setting PC on both the CPU cluster *and* the L2 cache, which have different timings: in the specific case of L2 the times are higher so these ones should be taken into account instead of the CPU ones. This parameter misconfiguration was not giving particular issues because on MSM8998 there was no CPU scaling at all, so cluster/L2 power collapse was rarely (if ever) hit. When CPU scaling is enabled, though, the wrong timings will produce SoC unstability shown to the user as random, apparently error-less, sudden reboots and/or lockups. This set of parameters are stabilizing the SoC when CPU scaling is ON and when power collapse is frequently hit.

[ Upstream commit f7a07f7 ] The firmware_loader can be used with a pre-allocated buffer through the use of the API calls: o request_firmware_into_buf() o request_partial_firmware_into_buf() If the firmware was built-in and present, our current check for if the built-in firmware fits into the pre-allocated buffer does not return any errors, and we proceed to tell the caller that everything worked fine. It's a lie and no firmware would end up being copied into the pre-allocated buffer. So if the caller trust the result it may end up writing a bunch of 0's to a device! Fix this by making the function that checks for the pre-allocated buffer return non-void. Since the typical use case is when no pre-allocated buffer is provided make this return successfully for that case. If the built-in firmware does *not* fit into the pre-allocated buffer size return a failure as we should have been doing before. I'm not aware of users of the built-in firmware using the API calls with a pre-allocated buffer, as such I doubt this fixes any real life issue. But you never know... perhaps some oddball private tree might use it. In so far as upstream is concerned this just fixes our code for correctness.

commit fe3d100 upstream. We should not walk/touch page tables outside of VMA boundaries when holding only the mmap sem in read mode. Evil user space can modify the VMA layout just before this function runs and e.g., trigger races with page table removal code since commit dd2283f ("mm: mmap: zap pages with read mmap_sem in munmap"). gfn_to_hva() will only translate using KVM memory regions, but won't validate the VMA. Further, we should not allocate page tables outside of VMA boundaries: if evil user space decides to map hugetlbfs to these ranges, bad things will happen because we suddenly have PTE or PMD page tables where we shouldn't have them. Similarly, we have to check if we suddenly find a hugetlbfs VMA, before calling get_locked_pte().

commit 85b6d24 upstream. Currently, the exit_shm() function not designed to work properly when task->sysvshm.shm_clist holds shm objects from different IPC namespaces. This is a real pain when sysctl kernel.shm_rmid_forced = 1, because it leads to use-after-free (reproducer exists). This is an attempt to fix the problem by extending exit_shm mechanism to handle shm's destroy from several IPC ns'es. To achieve that we do several things: 1. add a namespace (non-refcounted) pointer to the struct shmid_kernel 2. during new shm object creation (newseg()/shmget syscall) we initialize this pointer by current task IPC ns 3. exit_shm() fully reworked such that it traverses over all shp's in task->sysvshm.shm_clist and gets IPC namespace not from current task as it was before but from shp's object itself, then call shm_destroy(shp, ns). Note: We need to be really careful here, because as it was said before (1), our pointer to IPC ns non-refcnt'ed. To be on the safe side we using special helper get_ipc_ns_not_zero() which allows to get IPC ns refcounter only if IPC ns not in the "state of destruction". Q/A Q: Why can we access shp->ns memory using non-refcounted pointer? A: Because shp object lifetime is always shorther than IPC namespace lifetime, so, if we get shp object from the task->sysvshm.shm_clist while holding task_lock(task) nobody can steal our namespace. Q: Does this patch change semantics of unshare/setns/clone syscalls? A: No. It's just fixes non-covered case when process may leave IPC namespace without getting task->sysvshm.shm_clist list cleaned up.

commit 48b71a9 upstream. There are two sites that calls queue_work() after the destroy_workqueue() and lead to possible UAF.

For the above two UAF, the root cause is that the nfc_dev_up can race between the nci_unregister_device routine. Therefore, this patch introduce NCI_UNREG flag to easily eliminate the possible race. In addition, the mutex_lock in nci_close_device can act as a barrier.

commit 21631d2 upstream. The tx_skb_freelist elements are in a single linked list with the request id used as link reference. The per element link field is in a union with the skb pointer of an in use request. Move the link reference out of the union in order to enable a later reuse of it for requests which need a populated skb pointer. Rename add_id_to_freelist() and get_id_from_freelist() to add_id_to_list() and get_id_from_list() in order to prepare using those for other lists as well. Define ~0 as value to indicate the end of a list and place that value into the link for a request not being on the list. When freeing a skb zero the skb pointer in the request. Use a NULL value of the skb pointer instead of skb_entry_is_link() for deciding whether a request has a skb linked to it.

[ Upstream commit e5c6b31 ] The struct sugov_tunables is protected by the kobject, so we can't free it directly.
