Mat Martineau says: ==================== mptcp: Prevent tcp_push() crash and selftest temp file buildup These are two fixes for the net tree, addressing separate issues. Patch 1 addresses a divide-by-zero crash seen in syzkaller and also reported by a user on the netdev list. This changes MPTCP code so tcp_push() cannot be called with an invalid (0) mss_now value. Patch 2 fixes a selftest temp file cleanup issue that consumes excessive disk space when running repeated tests. ==================== Link: https://lore.kernel.org/r/20210901171537.121255-1-mathew.j.martineau@linux.intel.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 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.
