No problem looks like you already swallowed the hook :-) look at the following commit in your tree:
commit 2de4e82318c7f9d34f4b08599a612cd4cd10bf0b Author: Bernd Edlinger <bernd.edlinger@hotmail.de> Date: Fri Mar 20 21:26:19 2020 +0100
selftests/ptrace: add test cases for dead-locks
This adds test cases for ptrace deadlocks.
Additionally fixes a compile problem in get_syscall_info.c, observed with gcc-4.8.4:
get_syscall_info.c: In function 'get_syscall_info': get_syscall_info.c:93:3: error: 'for' loop initial declarations are only allowed in C99 mode for (unsigned int i = 0; i < ARRAY_SIZE(args); ++i) { ^ get_syscall_info.c:93:3: note: use option -std=c99 or -std=gnu99 to compile your code Signed-off-by: Bernd Edlinger <bernd.edlinger@hotmail.de> Reviewed-by: Kees Cook <keescook@chromium.org> Signed-off-by: Eric W. Biederman <ebiederm@xmission.com>
Test case 1/2 is working 2/2 is failing, deadlocking, I think even the time-out handler does not kill the dead-lock if I remember correctly.
And sorry, I anticipated part 15/16 and 16/16 would be pulled at the same time, so the glitch would not be visible by now.
Bernd.
