* | nptl: Fix racy pipe closing in tst-cancel{20,21} | Adhemerval Zanella | 2015-12-02 | 1 | -6/+9 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | The tst-cancel20 open two pipes and creates a thread which blocks reading the first pipe. It then issues a signal to activate the signal handler which in turn blocks reading the second pipe end. Finally the cancellation cleanup-up handlers are tested by first closing the all the pipes ends and issuing a pthread_cancel. The tst-cancel21 have a similar behavior, but use an extra fork after the test itself. The race condition occurs if the cancellation handling acts after the pipe close: in this case read will return EOF (indicating side-effects) and thus the cancellation must not act. However current GLIBC cancellation behavior acts regardless the syscalls returns with sid-effects. This patch adjust the test by moving the pipe closing after the cancellation handling. This avoid spurious cancellation if the case of the race described. Checked on x86_64 and i386. * nptl/tst-cancel20.c (do_one_test): Move the pipe closing after pthread_join. * nptl/tst-cancel21.c (tf): Likewise. | ||||
