2021-12-17Fix The GNU ToolChain Authors copyright noticeSiddhesh Poyarekar
I (and maybe one or two others) added a (C) to the copyright notice regardless of the contribution checklist[1] not mentioning it. Fix all these instances so that the notice reads as "Copyright The GNU Toolchain Authors" across the source code.

2021-08-12librt: add test (bug 28213)Nikita Popov
This test implements following logic: 1) Create POSIX message queue. Register a notification with mq_notify (using NULL attributes). Then immediately unregister the notification with mq_notify. Helper thread in a vulnerable version of glibc should cause NULL pointer dereference after these steps. 2) Once again, register the same notification. Try to send a dummy message. Test is considered successfulif the dummy message is successfully received by the callback function.
