commit d59f63f1c40771e80638bac447947e51c07e3ad4 Author: Simon South simon@simonsouth.net Date: Wed Nov 3 12:21:35 2021 -0400
test: Skip sandbox/stat_filename where "stat64" syscall defined
On 32-bit architectures where Linux provides the "stat64" system call, including i386, the sandbox is unable to filter calls to stat() as glibc uses this system call itself internally and the sandbox must allow it without restriction.
Update the sandbox unit tests to skip the "sandbox/stat_filename" test on systems where the "stat64" system call is defined and the test is certain to fail. Also reorder the "#if" statement's clauses to correspond with the comment preceding it, for clarity. --- src/test/test_sandbox.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
