2024-08-09binfmt_flat: Fix corruption when not offsetting data startKees Cook1-1/+3
Commit 04d82a6d0881 ("binfmt_flat: allow not offsetting data start") introduced a RISC-V specific variant of the FLAT format which does not allocate any space for the (obsolete) array of shared library pointers. However, it did not disable the code which initializes the array, resulting in the corruption of sizeof(long) bytes before the DATA segment, generally the end of the TEXT segment. Introduce MAX_SHARED_LIBS_UPDATE which depends on the state of CONFIG_BINFMT_FLAT_NO_DATA_START_OFFSET to guard the initialization of the shared library pointer region so that it will only be initialized if space is reserved for it.

2024-08-10rust: x86: remove `-3dnow{,a}` from target featuresMiguel Ojeda1-2/+2
LLVM 19 is dropping support for 3DNow! in commit f0eb5587ceeb ("Remove support for 3DNow!, both intrinsics and builtins. (#96246)"): Remove support for 3DNow!, both intrinsics and builtins. (#96246) This set of instructions was only supported by AMD chips starting in the K6-2 (introduced 1998), and before the "Bulldozer" family (2011). They were never much used, as they were effectively superseded by the more-widely-implemented SSE (first implemented on the AMD side in Athlon XP in 2001). This is being done as a predecessor towards general removal of MMX register usage. Since there is almost no usage of the 3DNow! intrinsics, and no modern hardware even implements them, simple removal seems like the best option. Thus we should avoid passing these to the backend, since otherwise we get a diagnostic about it: '-3dnow' is not a recognized feature for this target (ignoring feature) '-3dnowa' is not a recognized feature for this target (ignoring feature) We could try to disable them only up to LLVM 19 (not the C side one, but the one used by `rustc`, which may be built with a range of LLVMs). However, to avoid more complexity, we can likely just remove them altogether. According to Nikita [2]: > I don't think it's needed because LLVM should not generate 3dnow > instructions unless specifically asked to, using intrinsics that > Rust does not provide in the first place. Thus do so, like Rust did for one of their builtin targets [3]. For those curious: Clang will warn only about trying to enable them (`-m3dnow{,a}`), but not about disabling them (`-mno-3dnow{,a}`), so there is no change needed there.

2024-08-10kbuild: rust-analyzer: mark `rust_is_available.sh` invocation as recursiveMiguel Ojeda1-1/+1
When calling the `rust_is_available.sh` script, we need to make the jobserver available to it, as commit ecab4115c44c ("kbuild: mark `rustc` (and others) invocations as recursive") explains and did for the others. Otherwise, we get a warning from `rustc` when calling `make rust-analyzer` with parallel jobs, e.g. `-j8`. Using several jobs for that target does not really matter, but developers may call `make` with jobs enabled in all cases. Thus fix it.

2024-08-10kbuild: rust: skip -fmin-function-alignment in bindgen flagsZehui Xu1-1/+1
GCC 14 recently added -fmin-function-alignment option and the root Makefile uses it to replace -falign-functions when available. However, this flag can cause issues when passed to the Rust Makefile and affect the bindgen process. Bindgen relies on libclang to parse C code, and currently does not support the -fmin-function-alignment flag, leading to compilation failures when GCC 14 is used. This patch addresses the issue by adding -fmin-function-alignment to the bindgen_skip_c_flags in rust/Makefile. This prevents the flag from causing compilation issues. [ Matthew and Gary confirm function alignment should not change the ABI in a way that bindgen would care about, thus we did not need the extra logic for bindgen from v2. - Miguel ] Link: https://lore.kernel.org/linux-kbuild/[email protected]/ Signed-off-by: Zehui Xu <[email protected]> Reviewed-by: Alice Ryhl <[email protected]> Reviewed-by: Neal Gompa <[email protected]> Reviewed-by: Gary Guo <[email protected]> Link: https://lore.kernel.org/r/[email protected] [ Reworded title. - Miguel ] Signed-off-by: Miguel Ojeda <[email protected]>

When running the following: # cd /sys/kernel/tracing/ # echo 1 > events/sched/sched_waking/enable # echo 1 > events/sched/sched_switch/enable # echo 0 > tracing_on # dd if=per_cpu/cpu0/trace_pipe_raw of=/tmp/raw0.dat The dd task would get stuck in an infinite loop in the kernel. What would happen is the following: When ring_buffer_read_page() returns -1 (no data) then a check is made to see if the buffer is empty (as happens when the page is not full), it will call wait_on_pipe() to wait until the ring buffer has data. When it is it will try again to read data (unless O_NONBLOCK is set). The issue happens when there's a reader and the file descriptor is closed. The wait_on_pipe() will return when that is the case. But this loop will continue to try again and wait_on_pipe() will again return immediately and the loop will continue and never stop. Simply check if the file was closed before looping and exit out if it is.

2024-08-09module: make waiting for a concurrent module loader interruptibleLinus Torvalds1-15/+25
The recursive aes-arm-bs module load situation reported by Russell King is getting fixed in the crypto layer, but this in the meantime fixes the "recursive load hangs forever" by just making the waiting for the first module load be interruptible. This should now match the old behavior before commit 9b9879fc0327 ("modules: catch concurrent module loads, treat them as idempotent"), which used the different "wait for module to be ready" code in module_patient_check_exists(). End result: a recursive module load will still block, but now a signal will interrupt it and fail the second module load, at which point the first module will successfully complete loading.

2024-08-09usbnet: ipheth: fix carrier detection in modes 1 and 4Foster Snowhill1-2/+3
Apart from the standard "configurations", "interfaces" and "alternate interface settings" in USB, iOS devices also have a notion of "modes". In different modes, the device exposes a different set of available configurations. Depending on the iOS version, and depending on the current mode, the length and contents of the carrier state control message differs: * 1 byte (seen on iOS 4.2.1, 8.4): * 03: carrier off (mode 0) * 04: carrier on (mode 0) * 3 bytes (seen on iOS 10.3.4, 15.7.6): * 03 03 03: carrier off (mode 0) * 04 04 03: carrier on (mode 0) * 4 bytes (seen on iOS 16.5, 17.6): * 03 03 03 00: carrier off (mode 0) * 04 03 03 00: carrier off (mode 1) * 06 03 03 00: carrier off (mode 4) * 04 04 03 04: carrier on (mode 0 and 1) * 06 04 03 04: carrier on (mode 4) Before this change, the driver always used the first byte of the response to determine carrier state. From this larger sample, the first byte seems to indicate the number of available USB configurations in the current mode (with the exception of the default mode 0), and in some cases (namely mode 1 and 4) does not correlate with the carrier state. Previous logic erroneously counted `04 03 03 00` as "carrier on" and `06 04 03 04` as "carrier off" on iOS versions that support mode 1 and mode 4 respectively. Only modes 0, 1 and 4 expose the USB Ethernet interfaces necessary for the ipheth driver. Check the second byte of the control message where possible, and fall back to checking the first byte on older iOS versions.

This behaviour isn't observed on iPhone 11 on the same iOS version. The nature of these zero-length URBs is so far unknown. Drop RX URBs with no payload.

2024-08-09usbnet: ipheth: remove extraneous rx URB length checkFoster Snowhill1-6/+2
Rx URB length was already checked in ipheth_rcvbulk_callback_legacy() and ipheth_rcvbulk_callback_ncm(), depending on the current mode. The check in ipheth_rcvbulk_callback() was thus mostly a duplicate. The only place in ipheth_rcvbulk_callback() where we care about the URB length is for the initial control frame. These frames are always 4 bytes long. This has been checked as far back as iOS 4.2.1 on iPhone 3G. Remove the extraneous URB length check. For control frames, check for the specific 4-byte length instead. Signed-off-by: Foster Snowhill <[email protected]> Tested-by: Georgi Valkov <[email protected]> Signed-off-by: David S.

2024-08-09usbnet: ipheth: race between ipheth_close and error handlingOliver Neukum1-1/+1
ipheth_sndbulk_callback() can submit carrier_work as a part of its error handling. That means that the driver must make sure that the work is cancelled after it has made sure that no more URB can terminate with an error condition. Hence the order of actions in ipheth_close() needs to be inverted.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Have reading of event format files test if the metadata still exists. When a event is freed, a flag (EVENT_FILE_FL_FREED) in the metadata is set to state that it is to prevent any new references to it from happening while waiting for existing references to close. When the last reference closes, the metadata is freed. But the "format" was missing a check to this flag (along with some other files) that allowed new references to happen, and a use-after-free bug to occur. - Have the trace event meta data use the refcount infrastructure instead of relying on its own atomic counters. - Have tracefs inodes use alloc_inode_sb() for allocation instead of using kmem_cache_alloc() directly. - Have eventfs_create_dir() return an ERR_PTR instead of NULL as the callers expect a real object or an ERR_PTR. - Have release_ei() use call_srcu() and not call_rcu() as all the protection is on SRCU and not RCU. - Fix ftrace_graph_ret_addr() to use the task passed in and not current. - Fix overflow bug in get_free_elt() where the counter can overflow the integer and cause an infinite loop. - Remove unused function ring_buffer_nr_pages() - Have tracefs freeing use the inode RCU infrastructure instead of creating its own. When the kernel had randomize structure fields enabled, the rcu field of the tracefs_inode was overlapping the rcu field of the inode structure, and corrupting it. Instead, use the destroy_inode() callback to do the initial cleanup of the code, and then have free_inode() free it. * tag 'trace-v6.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracefs: Use generic inode RCU for synchronizing freeing ring-buffer: Remove unused function ring_buffer_nr_pages() tracing: Fix overflow in get_free_elt() function_graph: Fix the ret_stack used by ftrace_graph_ret_addr() eventfs: Use SRCU for freeing eventfs_inodes eventfs: Don't return NULL in eventfs_create_dir() tracefs: Fix inode allocation tracing: Use refcount for trace_event_file reference counter tracing: Have format file honor EVENT_FILE_FL_FREED

2024-08-08selinux: revert our use of vma_is_initial_heap()Paul Moore1-1/+11
Unfortunately it appears that vma_is_initial_heap() is currently broken for applications that do not currently have any heap allocated, e.g. brk == start_brk. The breakage is such that it will cause SELinux to check for the process/execheap permission on memory regions that cross brk/start_brk even when there is no heap. The proper fix would be to correct vma_is_initial_heap(), but as there are multiple callers I am hesitant to unilaterally modify the helper out of concern that I would end up breaking some other subsystem. The mm developers have been made aware of the situation and hopefully they will have a fix at some point in the future, but we need a fix soon so we are simply going to revert our use of vma_is_initial_heap() in favor of our old logic/code which works as expected, even in the face of a zero size heap. We can return to using vma_is_initial_heap() at some point in the future when it is fixed.

2024-08-08ASoC: meson: axg-fifo: fix irq scheduling issue with PREEMPT_RTJerome Brunet1-16/+10
With PREEMPT_RT enabled a spinlock_t becomes a sleeping lock. This is usually not a problem with spinlocks used in IRQ context since IRQ handlers get threaded. However, if IRQF_ONESHOT is set, the primary handler won't be force-threaded and runs always in hardirq context. This is a problem because spinlock_t requires a preemptible context on PREEMPT_RT. In this particular instance, regmap mmio uses spinlock_t to protect the register access and IRQF_ONESHOT is set on the IRQ. In this case, it is actually better to do everything in threaded handler and it solves the problem with PREEMPT_RT.
