Paolo Abeni says: ==================== mptcp: fix MP_JOIN failure handling Currently if we hit an MP_JOIN failure on the third ack, the child socket is closed with reset, but the request socket is not deleted, causing weird behaviors. The main problem is that MPTCP's MP_JOIN code needs to plug it's own 'valid 3rd ack' checks and the current TCP callbacks do not allow that. This series tries to address the above shortcoming introducing a new MPTCP specific bit in a 'struct tcp_request_sock' hole, and leveraging that to allow tcp_check_req releasing the request socket when needed. The above allows cleaning-up a bit current MPTCP hooking in tcp_check_req(). An alternative solution, possibly cleaner but more invasive, would be changing the 'bool *own_req' syn_recv_sock() argument into 'int *req_status' and let MPTCP set it to 'REQ_DROP'. v1 -> v2: - be more conservative about drop_req initialization RFC -> v1: - move the drop_req bit inside tcp_request_sock (Eric) ==================== Signed-off-by: David S.

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.
