[ Upstream commit d3d863036d688313f8d566b87acd7d99daf82749 ] If the local processor work item for the rxrpc local endpoint gets requeued by an event (such as an incoming packet) between it getting scheduled for destruction and the UDP socket being closed, the rxrpc_local_destroyer() function can get run twice. The second time it can hang because it can end up waiting for cleanup events that will never happen. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
