Two fixes: - 9p now uses a variable size for its recv buffer, but every place hadn't been updated properly to use it and some buffer overflows have been found and needed fixing. There's still one place where msize is incorrectly used in a safety check (p9_check_errors), but all paths leading to it should already be avoiding overflows and that patch took a bit more time to get right for zero-copy requests so I'll send it for 6.2 - yet another race condition in p9_conn_cancel introduced by a fix of a syzbot report in the same place, maybe at some point we'll get it right without burning it all down... -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE/IPbcYBuWt0zoYhOq06b7GqY5nAFAmN9q0QACgkQq06b7GqY 5nAYfhAAkV4BuDAxkq1J9m2tAr32bNgSWRbwHGoiO3yOgN3OQcl0MRR910VLPaBe rRMbggIZKp6SjKpL5CQUbIcf+ubvcHZQpglCWdJT6Cch9VAidwKB4y48V0nb9Gos Z2lAtKCdlczmmbYY+KQ4KrFXKXkHXV7FPH7aLLaVg6VxckbRwunDMAPIQJ2wtUDq GP+J0OBL6NGb1N1TrAx9uQMzM9Zbu/pfQ8Ik/PdwzcT5fWm6OOlICOe/ImAlFfiN AU0+jc1c01DhQiGedEytOLWMlvcUtgbN2VoMszAuIdn3MFdRFiklQ/5IYFvEu4z4 vWeSL5ctsrgqhG0i5gNTDspzmX05amBaN7UOyQ8yvCYs9Jgv7x9EghdXA4XMX3UD l8QcNQgthTVtI2waspAmWOV4anPjr4VJIcoLKapzAXTpd7SCJazzap/0CvXjTINK IX4Fjeg9eKeQPsHgeLiO00zokM0LPZ+W4X6Xus1rrwzHVtde78bqokrUV/U6wVKF UT0i06oEYlB79ySOmgqoZuFRbos7VZI6l6hLkbo+XJOPalWzP5MwexGS2JVo4ymS Xu5DYlqnSdQQxScHdK906Ksbusa3n5jxAURqOIQxJ1UZyC7CPusVy2KA4FiZsL/x OkYGlSg60tvsOfaNQoXOlziG2u3FJrZFjsurvgBgsgtUWEgVaU0= =MQOZ -----END PGP SIGNATURE----- Merge tag '9p-for-6.1-rc7' of https://github.com/martinetd/linux Pull 9p fixes from Dominique Martinet: - 9p now uses a variable size for its recv buffer, but every place hadn't been updated properly to use it and some buffer overflows have been found and needed fixing.

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.
