I got the following failure: ptrace03 0 WARN : ptrace() returned 0; errno: 0, Success ptrace03 1 FAIL : Test Failed ptrace03 2 PASS : Test Passed ptrace03 3 PASS : Test Passed
This is because the latest kernel allows init process to be traced. The commit is: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=00cd5c37afd5f431ac186dd131705048c0a11fdb See the discussion in LKML: http://marc.info/?t=120628018600001 So we should not execute this test case if the kernel version is above 2.6.25. Here is the test result after patching (linux 2.6.26-rc2): ptrace03 1 CONF : this kernel allows to trace init ptrace03 2 PASS : Test Passed ptrace03 3 PASS : Test Passed Signed-off-by: Li Zefan <[EMAIL PROTECTED]> --- ptrace03.c | 10 ++++++++++ 1 file changed, 10 insertions(+) diff -Nurp ltp-full-20080430.orig/testcases/kernel/syscalls/ptrace/ptrace03.c ltp-full-20080430/testcases/kernel/syscalls/ptrace/ptrace03.c --- ltp-full-20080430.orig/testcases/kernel/syscalls/ptrace/ptrace03.c 2008-05-08 09:55:54.000000000 +0800 +++ ltp-full-20080430/testcases/kernel/syscalls/ptrace/ptrace03.c 2008-05-21 10:10:29.000000000 +0800 @@ -34,6 +34,8 @@ * Verifies that * 1) ptrace() returns -1 & sets errno to EPERM while tring to trace * process 1 + * (This test case will be executed only if the kernel version + * is 2.6.25 or below) * 2) ptrace() returns -1 & sets errno to ESRCH if process with * specified pid does not exist * 3) ptrace() returns -1 & sets errno to EPERM if we are trying @@ -137,6 +139,14 @@ main(int ac, char **av) for (i = 0; i < TST_TOTAL; ++i) { + /* since Linux 2.6.26, it's allowed to trace init, + so just skip this test case */ + if (i == 0 && tst_kvercmp(2,6,25) > 0) { + tst_resm(TCONF, + "this kernel allows to trace init"); + continue; + } + /* fork() */ switch (child_pid = FORK_OR_VFORK()) { ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
