It is common for services to be stateless around their main event loop.
If a process sets PR_SET_IDLE to PR_IDLE_MODE_KILLME then it
signals to the kernel that epoll_wait() and friends may not complete,
and the kernel may send SIGKILL if resources get tight.
See my systemd patch:
It is common for services to be stateless around their main event loop.
If a process sets PR_SET_IDLE to PR_IDLE_MODE_KILLME then it
signals to the kernel that epoll_wait() and friends may not complete,
and the kernel may send SIGKILL if resources get tight.
See my systemd patch:
It is common for services to be stateless around their main event loop.
If a process passes the EPOLL_KILLME flag to epoll_wait5() then it
signals to the kernel that epoll_wait5() may not complete, and the kernel
may send SIGKILL if resources get tight.

algif_hash and algif_skcipher used MSG_MORE from tcp_sendpages()
and need to see the new flag as identical to MSG_MORE.

The offending commit also got backported to the 3.2 stable kernel, so
we need this fix there as well.
