Currently, three functions from utils.c are tested. - Add --stack-format option In addition to stopping stack pointer decoding (with -s/--stack option) on first unresolvable pointer, allow also skipping unresolvable pointers and displaying everything, configurable with a new option. - Unify number of CPUs into one global variable Use one global variable, nr_cpus, to store the number of CPUs instead of retrieving it and passing it at multiple places. - Fix behavior in various corner cases Make RTLA behave correctly in several corner cases: memory allocation failure, invalid value read from kernel side, thread creation failure, malformed time value input, and read/write failure or interruption by signal. - Improve string handling Simplify several places in the code that handle strings, including parsing of action arguments. A few new helper functions and variables are added for that purpose. - Get rid of magic numbers Few places handling paths use a magic number of 1024. Replace it with MAX_PATH and ARRAY_SIZE() macro. - Unify threshold handling Code that handles response to latency threshold is duplicated between tools, which has led to bugs in the past. Unify it into a new helper as much as possible. - Fix segfault on SIGINT during cleanup The SIGINT handler touches dynamically allocated memory. Detach it before freeing it during cleanup to prevent segmentation fault and discarding of output buffers. Also, properly document SIGINT handling while at it.* tag 'trace-rtla-v7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: (28 commits) Documentation/rtla: Document SIGINT behavior rtla: Fix segfault on multiple SIGINTs rtla/utils: Fix loop condition in PID validation rtla/utils: Fix resource leak in set_comm_sched_attr() rtla/trace: Fix I/O handling in save_trace_to_file() rtla/trace: Fix write loop in trace_event_save_hist() rtla/timerlat: Simplify RTLA_NO_BPF environment variable check rtla: Use str_has_prefix() for option prefix check rtla: Enforce exact match for time unit suffixes rtla: Use str_has_prefix() for prefix checks rtla: Add str_has_prefix() helper function rtla: Handle pthread_create() failure properly rtla/timerlat: Add bounds check for softirq vector rtla: Simplify code by caching string lengths rtla: Replace magic number with MAX_PATH rtla: Introduce common_threshold_handler() helper rtla/actions: Simplify argument parsing rtla: Use strdup() to simplify code rtla: Exit on memory allocation failures during initialization tools/rtla: Remove unneeded nr_cpus from for_each_monitored_cpu ...
