I got the following failure: adjtimex02 1 PASS : Test Passed, adjtimex() returned -1 with errno: 14 adjtimex02 2 PASS : Test Passed, adjtimex() returned -1 with errno: 22 adjtimex02 3 PASS : Test Passed, adjtimex() returned -1 with errno: 22 adjtimex02 4 FAIL : Test Failed, adjtimex()returned 5, errno = 0 : Success adjtimex02 5 FAIL : Test Failed, adjtimex()returned 5, errno = 0 : Success adjtimex02 6 PASS : Test Passed, adjtimex() returned -1 with errno: 1
This is because the latest kernel normalizes buf.offset value if it is outside the acceptable range. The commit is: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=eea83d896e318bda54be2d2770d2c5d6668d11db So we should not execute this test case if the kernel version is above 2.6.25.
