[ Upstream commit063c60d391] Fix rxrpc_new_incoming_call() to check that we have a suitable service key available for the combination of service ID and security class of a new incoming call - and to reject calls for which we don't. This causes an assertion like the following to appear: rxrpc: Assertion failed - 6(0x6) == 12(0xc) is false kernel BUG at net/rxrpc/call_object.c:456! Where call->state is RXRPC_CALL_SERVER_SECURING (6) rather than RXRPC_CALL_COMPLETE (12). Fixes:248f219cb8("rxrpc: Rewrite the data and ack handling code") Reported-by: Marc Dionne <marc.dionne@auristor.com> 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.
