commit 5a81e6a171 upstream.
Flags (PIPE_BUF_FLAG_PACKET, PIPE_BUF_FLAG_GIFT) could remain on the
unused part of the pipe ring buffer. Previously splice_to_pipe() left
the flags value alone, which could result in incorrect behavior.
Uninitialized flags appears to have been there from the introduction of
the splice syscall.
