Hi Mimi, > The first two patches are fine. From the test, I'm seeing the > following results: Thanks a lot for reviewing and testing. > evm_overlay 1 TINFO: overwrite file in overlay > tst_rod: Failed to open '(null)' for writing: Operation not permitted > evm_overlay 1 TFAIL: echo overlay > mntpoint/merged/foo1.txt failed unexpectedly I've fixed '(null)' [1], with that one applied it should be 'mntpoint/merged/foo1.txt' But what is strange to me is that it continues to execute second line. return 1 [2] should cause ROD() to quit with TBROK [3]. Maybe that ROD in test1() should be replaced EXPECT_PASS. > evm_overlay 2 TINFO: append file in overlay: mntpoint/lower/foo2.txt > evm_overlay 2 TPASS: echo overlay >> mntpoint/merged/foo2.txt passed as expected > evm_overlay 3 TINFO: create a new file in overlay > evm_overlay 3 TPASS: echo overlay > mntpoint/merged/foo3.txt passed as expected > evm_overlay 4 TINFO: read all created files > evm_overlay 4 TFAIL: cat mntpoint/merged/foo1.txt > /dev/null 2> /dev/null failed unexpectedly > evm_overlay 4 TFAIL: cat mntpoint/merged/foo2.txt > /dev/null 2> /dev/null failed unexpectedly > evm_overlay 4 TFAIL: cat mntpoint/merged/foo3.txt > /dev/null 2> /dev/null failed unexpectedly > evm_overlay 5 TINFO: SELinux enabled in enforcing mode, this may affect test results > evm_overlay 5 TINFO: You can try to disable it with TST_DISABLE_SELINUX=1 (requires super/root) > evm_overlay 5 TINFO: loaded SELinux profiles: none > With "evm: instead of using the overlayfs i_ino, use the real i_ino" > patch, I'm only seeing the first failure. > Mimi Kind regards, Petr [1] https://github.com/linux-test-project/ltp/commit/8a35daf6bb175391fd43cd28d9ca2d0d5b06157c [2] https://github.com/linux-test-project/ltp/blob/master/testcases/lib/tst_rod.c#L117 [3] https://github.com/linux-test-project/ltp/blob/master/testcases/lib/tst_test.sh#L150
