Dmitry V. Levin	fdb2a1867e	tests: adjust rt_sigpending to older kernels ... With linux kernels older than v3.9-rc1, compat rt_sigpending syscall could fail with EFAULT in cases where on later kernels it succeeds. Adjust the test to handle both cases properly. * tests/rt_sigpending.c (iterate): Stop iterations if rt_sigpending failed with EFAULT.	2016-04-20 01:08:13 +00:00
Dmitry V. Levin	11656206ff	Fix corner cases of rt_sigpending syscall decoder ... * signal (print_sigset_addr_len_limit): New function, cloned from print_sigset_addr_len with added minimal length argument. Treat length less than minimal length or greater than NSIG/8 as invalid. Do not align length to 4-byte boundary. Align destination buffer to 4-byte boundary and initialize it with zeroes so that subsequent call to sprintsigmask_n will not access uninitialized data. (print_sigset_addr_len): Turn into a wrapper around print_sigset_addr_len_limit with current_wordsize as a minimal length argument. (SYS_FUNC(rt_sigpending)): Call print_sigset_addr_len_limit instead of print_sigset_addr_len with 1 as a minimal length argument. * tests/rt_sigpending.c: New file. * tests/rt_sigpending.test: New test. * tests/.gitignore: Add rt_sigpending. * tests/Makefile.am (check_PROGRAMS): Likewise. (TESTS): Add rt_sigpending.test.	2016-02-19 01:44:33 +00:00
