running in a container with a user namespace, if you call getxattr with name = "system.posix_acl_access" and size % 8 != 4, then getxattr silently skips the user namespace fixup that it normally does resulting in un-fixed-up data being returned.
This is caused by posix_acl_fix_xattr_to_user() being passed the total buffer size and not the actual size of the xattr as returned by vfs_getxattr().
This issue can be triggered by running the getxattr05 test in ubuntu_ltp_syscalls test suite.
== Fix ==
82c9a927bc5d ("getxattr: use correct xattr length")
A test kernel could be found here: http://people.canonical.com/~phlin/kernel/lp-1798013-getxattr05/
== Regression Potential ==
Low, this fix just passes the actual length of the xattr as returned by vfs_getxattr() down.
== Test Case ==
Run the getxattr05 test in ubuntu_ltp_syscalls test suite.

== Justification ==
This issue has been addressed in bug 1789746 for other kernels
When the getxattr05 test in ubuntu_ltp_syscalls test suite, the test will failed with:
tag=getxattr05 stime=1539663573
cmdline="getxattr05"
contacts=""
analysis=exit
<<<test_output>>>
incrementing stop
tst_test.c:1072: INFO: Timeout per run is 0h 05m 00s
getxattr05.c:85: PASS: Got same data when acquiring the value of system.posix_acl_access twice
getxattr05.c:80: FAIL: Got different data(00 != ffffffff) at 16
getxattr05.c:85: PASS: Got same data when acquiring the value of system.posix_acl_access twice
Summary:
passed 2
failed 1
skipped 0
warnings 0
This is caused by posix_acl_fix_xattr_to_user() being passed the total buffer size and not the actual size of the xattr as returned by vfs_getxattr().
== Fix ==
82c9a927bc5d ("getxattr: use correct xattr length")
A test kernel for Trusty could be found here:
http://people.canonical.com/~phlin/kernel/lp-1798013-getxattr05/
== Regression Potential ==
Low, this one-liner fix just passes the actual length of the xattr as returned by vfs_getxattr() down.
== Test Case ==
Run the getxattr05 test in ubuntu_ltp_syscalls test suite.

Run the getxattr05 test in ubuntu_ltp_syscalls test suite. And it will pass with the patched kernel.
