Gur Stavi says: ==================== net: af_packet: allow joining a fanout when link is down PACKET socket can retain its fanout membership through link down and up and leave a fanout while closed regardless of link state. However, socket was forbidden from joining a fanout while it was not RUNNING. This scenario was identified while studying DPDK pmd_af_packet_drv. Since sockets are only created during initialization, there is no reason to fail the initialization if a single link is temporarily down. This patch allows PACKET socket to join a fanout while not RUNNING. Selftest psock_fanout is extended to test this "fanout while link down" scenario. Selftest psock_fanout is also extended to test fanout create/join by socket that did not bind or specified a protocol, which carries an implicit bind. v3: https://lore.kernel.org/cover.1728555449.git.gur.stavi@huawei.com v2: https://lore.kernel.org/cover.1728382839.git.gur.stavi@huawei.com v1: https://lore.kernel.org/cover.1728303615.git.gur.stavi@huawei.com ==================== Link: https://patch.msgid.link/cover.1728802323.git.gur.stavi@huawei.com Signed-off-by: Jakub Kicinski <kuba@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 reStructuredText 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.
