ubuntu_qrt_kernel_security test_050_personality failed on arm64 Trusty / X-hwe kernel

[Po-Hsu Lin]

With 4.4.0-74.95~14.04.1 kernel, this test case failed on arm64 node.

(This issue was reported in bug 1630000 as well, in this cycle, only 050, 060 failed on this kernel)

Hi,

Are these tests (050 and 060 in bug 1684773) failing only for the 4.4 arm64 kernel on trusty, and not the same 4.4 kernel in xenial? If so, I'm wondering if the difference is in the init daemon in the two releases, rather than the kernel.

Thanks.

Oh sorry missed this comment.

Yes, they both failed for the 4.4 arm64 kernel on trusty.

The qrt security test suite passed on 4.4 Xenial.

Thanks!

Failed with Trusty kernel on Trusty too.

sam, any reason to keep this open? i see random updates on it, yet have no looked at the issue in its entirety.

 very old bug, with no action on it, marking bug as incomplete and will close in 5 days if no update.

[Po-Hsu Lin (cypressyew)]

This issue still exists

As we're not testing ARM64 on Trusty ESM anymore, I will close this.

Please feel free to re-open this if think this is not correct.
