2026-01-07x86/alternative: Use helper functions for patching alternativesJuergen Gross
Tidy up apply_alternatives() by moving the main patching action of a single alternative instance into 3 helper functions: - analyze_patch_site() for selection whether patching should occur or not and to handle nested alternatives. - prep_patch_site() for applying any needed relocations and issuing debug prints for the site. - patch_site() doing the real patching action, including optimization of any padding NOPs. In prep_patch_site() use __apply_relocation() instead of text_poke_apply_relocation(), as the NOP optimization is now done in patch_site() for all cases.

2026-01-07rtla: Fix parse_cpu_set() return value documentationWander Lairson Costa
Correct the return value documentation for parse_cpu_set() function in utils.c. The comment incorrectly stated that the function returns 1 on success and 0 on failure, but the actual implementation returns 0 on success and 1 on failure, following the common error-on-nonzero convention used throughout the codebase. This documentation fix ensures that developers reading the code understand the correct return value semantics and prevents potential misuse of the function's return value in conditional checks.

2026-01-07rtla: Ensure null termination after read operations in utils.cWander Lairson Costa
Add explicit null termination and buffer initialization for read() operations in procfs_is_workload_pid() and get_self_cgroup() functions. The read() system call does not null-terminate the data it reads, and when the buffer is filled to capacity, subsequent string operations will read past the buffer boundary searching for a null terminator. In procfs_is_workload_pid(), explicitly set buffer[MAX_PATH-1] to '\0' to ensure the buffer is always null-terminated before passing it to strncmp(). In get_self_cgroup(), use memset() to zero the path buffer before reading, which ensures null termination when retval is less than MAX_PATH. Additionally, set path[MAX_PATH-1] to '\0' after the read to handle the case where the buffer is filled completely. These defensive buffer handling practices prevent potential buffer overruns and align with the ongoing buffer safety improvements across the rtla codebase.

2026-01-07rtla: Make stop_tracing variable volatileWander Lairson Costa
The stop_tracing global variable is accessed from both the signal handler context and the main program flow without synchronization. This creates a potential race condition where compiler optimizations could cache the variable value in registers, preventing the signal handler's updates from being visible to other parts of the program. Add the volatile qualifier to stop_tracing in both common.c and common.h to ensure all accesses to this variable bypass compiler optimizations and read directly from memory. This guarantees that when the signal handler sets stop_tracing, the change is immediately visible to the main program loop, preventing potential hangs or delayed shutdown when termination signals are received.

2026-01-07rtla: Add generated output files to gitignoreWander Lairson Costa
The rtla tool generates various output files during testing and execution, including custom trace outputs and histogram data. These files are artifacts of running the tool with different options and should not be tracked in version control. Add gitignore entries for custom_filename.txt, osnoise_irq_noise_hist.txt, osnoise_trace.txt, and timerlat_trace.txt to prevent accidentally committing these generated files. This aligns with the existing pattern of ignoring build artifacts and generated headers like *.skel.h.

2026-01-07rtla: Fix NULL pointer dereference in actions_parseWander Lairson Costa
The actions_parse() function uses strtok() to tokenize the trigger string, but does not check if the returned token is NULL before passing it to strcmp(). If the trigger parameter is an empty string or contains only delimiter characters, strtok() returns NULL, causing strcmp() to dereference a NULL pointer and crash the program. This issue can be triggered by malformed user input or edge cases in trigger string parsing. Add a NULL check immediately after the strtok() call to validate that a token was successfully extracted before using it. If no token is found, the function now returns -1 to indicate a parsing error.

2026-01-07rtla: Replace atoi() with a robust strtoi()Wander Lairson Costa
The atoi() function does not perform error checking, which can lead to undefined behavior when parsing invalid or out-of-range strings. This can cause issues when parsing user-provided numerical inputs, such as signal numbers, PIDs, or CPU lists. To address this, introduce a new strtoi() helper function that safely converts a string to an integer. This function validates the input and checks for overflows, returning a negative value on failure. Replace all calls to atoi() with the new strtoi() function and add proper error handling to make the parsing more robust and prevent potential issues.

2026-01-07rtla: Set stop threshold after all instances are enabledCrystal Wood
This avoids startup races where one of the instances hit a threshold before all instances were enabled, and thus tracing stops without the relevant event. In particular, this is not uncommon with the tests that set a very tight threshold and then complain if there's no analysis. This also ensures that we don't stop tracing during a warmup. The downside is a small chance of having an event over the threshold early in the output, without stopping on it, which could cause user confusion. This should be less likely if the warmup feature is used, but that doesn't eliminate the race window, just the odds of an unusual spike right at that moment.

2026-01-07dt-bindings: pinctrl: sunxi: Allow pinmux sub-pattern with leading numbersChen-Yu Tsai
The pattern for pinmux node names is typically the peripheral name and instance number, followed by pingroup name if there are multiple options. Normally the instance number is directly appended to the peripheral name, like "mmc0" or "i2c2". But if the peripheral name ends with a number, then it becomes confusing. On the A20, the PS2 interface controller has two instances. This produces pinmux node names like "ps2-0-pins". Make the sub-pattern "[0-9]-" valid to fit this pattern.

Similar to commit 835a50753579 ("selftests/bpf: Add -fms-extensions to bpf build flags") and commit 639f58a0f480 ("bpftool: Fix build warnings due to MS extensions") The kernel is now built with -fms-extensions, therefore generated vmlinux.h contains types like: struct slab { .. struct freelist_counters; }; Use -fms-extensions and -Wno-microsoft-anon-tag flags to build bpf programs that #include "vmlinux.h" Signed-off-by: Benjamin Tissoires <bentiss@kernel.org>

2026-01-07ARM: dts: meson: drop iio-hwmon in favour of generic-adc-thermalMartin Blumenstingl
Commit 85b21fdec906e ("thermal/drivers/generic-adc: Register thermal zones as hwmon sensors") made "generic-adc-thermal" also register hwmon attributes. That means we now have the temperature sensor shown twice: - once from iio-hwmon - and another time from generic-adc-thermal We need the latter for SoC temperature control, so simply drop the former so userspace doesn't see duplicate sensors. Also generic-adc-thermal provides a better name to userspace ("soc_thermal-virtual-0") than iio_hwmon.
