tools/thermal: Fix possible path truncations

2022-08-21T13:16:12+00:00

[ Upstream commit 6c58cf40e3a1d2f47c09d3489857e9476316788a ] A build with -D_FORTIFY_SOURCE=2 enabled will produce the following warnings: sysfs.c:63:30: warning: '%s' directive output may be truncated writing up to 255 bytes into a region of size between 0 and 255 [-Wformat-truncation=] snprintf(filepath, 256, "%s/%s", path, filename); ^~ Bump up the buffer to PATH_MAX which is the limit and account for all of the possible NUL and separators that could lead to exceeding the allocated buffer sizes.

thermal/tools/tmon: Include pthread and time headers in tmon.h

2022-08-21T13:15:37+00:00

[ Upstream commit 0cf51bfe999524377fbb71becb583b4ca6d07cfc ] Include sys/time.h and pthread.h in tmon.h, so that types "pthread_mutex_t" and "struct timeval tv" are known when tmon.h references them. Without these headers, compiling tmon against musl-libc will fail with these errors: In file included from sysfs.c:31:0: tmon.h:47:8: error: unknown type name 'pthread_mutex_t' extern pthread_mutex_t input_lock; ^~~~~~~~~~~~~~~ make[3]: *** [: sysfs.o] Error 1 make[3]: *** Waiting for unfinished jobs....

tools/thermal: tmon: fix for segfault

2018-03-27T07:51:23+00:00

Fixes a segfault occurring when e.g. is pressed multiple times in the ncurses tmon application. The segfault is caused by incrementing cur_thermal_record in the main function without checking if it's value reached NR_THERMAL_RECORD immediately. Since the boundary check only occurred in update_thermal_data a race condition existed, which lead to an attempted read beyond the last element of the trec array. The fix was implemented by moving the cur_thermal_record incrementation to the update_thermal_data function using a temporary variable on which the boundary condition is checked before updating cur_thread_record, so that the variable is never incremented beyond the trec array's boundary. It seems the segfault does not occur on every machine: On a HP EliteBook G4 the segfault happens, while it does not happen on a Thinkpad T540p. Signed-off-by: Frank Asseg Signed-off-by: Jiri Kosina
