mainlining shenanigans
6dcc4e3838
Ciara Loftus says: ==================== This series fixes some issues around socket creation for AF_XDP. Patch 1 fixes a potential NULL pointer dereference in xsk_socket__create_shared. Patch 2 ensures that the umem passed to xsk_socket__create(_shared) remains unchanged in event of failure. Patch 3 makes it possible for xsk_socket__create(_shared) to succeed even if the rx and tx XDP rings have already been set up by introducing a new fields to struct xsk_umem which represent the ring setup status for the xsk which shares the fd with the umem. v3->v4: * Reduced nesting in xsk_put_ctx as suggested by Alexei. * Use bools instead of a u8 and flags to represent the ring setup status as suggested by Björn. v2->v3: * Instead of ignoring the return values of the setsockopt calls, introduce a new flag to determine whether or not to call them based on the ring setup status as suggested by Alexei. v1->v2: * Simplified restoring the _save pointers as suggested by Magnus. * Fixed the condition which determines whether to unmap umem rings when socket create fails. ==================== Acked-by: Björn Töpel <bjorn@kernel.org> Signed-off-by: Alexei Starovoitov <ast@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.
