Intermitent failure of LTP shmat01 testcase

[Tixy (Jon Medhurst)]

The ARM LT vexpress CI job [1] runs the LTP test suite and the shmat01 test case in this seems to fail about half the time with:

shmat01 1 TFAIL : shmat call failed: TEST_ERRNO=EINVAL(22): Invalid argument

Example of a test run with a fail, is

and a pass is

This looks like a bug with the test case which has been fixed in the upstream LTP project by commit f9135588 (ipc/shmat: pick suitable base_addr before each testcase). We should update the CI jobs to use a more recent LTP release. Currently we are two releases (6 months) behind.

I changed this bug to Linaro QA Services, I hope it's the right team. Basically, the test case needs updating to the latest version, so isn't a landing team problem.

The builds in the original bug were using lava_test_run. The most recent builds use lava_test_shell with test definition coming from qa/test-definitios.git. The ubuntu/ltp.yaml downloads the latest LTP sources:
http://sourceforge.net/projects/ltp/files/LTP%20Source/ltp-20130904/ltp-full-20130904.tar.xz

shmat01 passes in the last buld:

Is this bug still reproducible?
