selftests/core: fix conflicting types compile error for close_range()

2021-11-18T13:04:01+00:00

[ Upstream commit f35dcaa0a8a29188ed61083d153df1454cf89d08 ] close_range() test type conflicts with close_range() library call in x86_64-linux-gnu/bits/unistd_ext.h. Fix it by changing the name to core_close_range(). gcc -g -I../../../../usr/include/ close_range_test.c -o ../tools/testing/selftests/core/close_range_test In file included from close_range_test.c:16: close_range_test.c:57:6: error: conflicting types for ‘close_range’; have ‘void(struct __test_metadata *)’ 57 | TEST(close_range) | ^~~~~~~~~~~ ../kselftest_harness.h:181:21: note: in definition of macro ‘__TEST_IMPL’ 181 | static void test_name(struct __test_metadata *_metadata); \ | ^~~~~~~~~ close_range_test.c:57:1: note: in expansion of macro ‘TEST’ 57 | TEST(close_range) | ^~~~ In file included from /usr/include/unistd.h:1204, from close_range_test.c:13: /usr/include/x86_64-linux-gnu/bits/unistd_ext.h:56:12: note: previous declaration of ‘close_range’ with type ‘int(unsigned int, unsigned int, int)’ 56 | extern int close_range (unsigned int __fd, unsigned int __max_fd, | ^~~~~~~~~~~ Signed-off-by: Shuah Khan Signed-off-by: Sasha Levin

XFAIL is gone since commit 9847d24af95c ("selftests/harness: Refactor XFAIL into SKIP"), use SKIP instead. Fixes: 9847d24af95c ("selftests/harness: Refactor XFAIL into SKIP") Signed-off-by: Tommi Rantala Reviewed-by: Kees Cook Acked-by: Christian Brauner Signed-off-by: Shuah Khan

tests: add close_range() tests

2020-06-16T22:07:38+00:00

This adds basic tests for the new close_range() syscall. - test that no invalid flags can be passed - test that a range of file descriptors is correctly closed - test that a range of file descriptors is correctly closed if there there are already closed file descriptors in the range - test that max_fd is correctly capped to the current fdtable maximum Signed-off-by: Christian Brauner Cc: Arnd Bergmann Cc: Jann Horn Cc: David Howells Cc: Dmitry V.
