This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed- xenial'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

The implementation of pthread_set/getname_np however needs access to /proc/<pid>/task/<tid>/comm. If PR_DUMPABLE is false this implementation is locked out. This patch installs a special permission function for the file "comm" that grants read and write access to all threads of the same group regardless of the ownership of the inode. For all other threads the function falls back to the generic inode permission check.
