Davide Caratti says: ==================== net/sched: use the backlog for nested mirred ingress TC mirred has a protection against excessive stack growth, but that protection doesn't really guarantee the absence of recursion, nor it guards against loops. Patch 1/2 rewords "recursion" to "nesting" to make this more clear. We can leverage on this existing mechanism to prevent TCP / SCTP from doing soft lock-up in some specific scenarios that uses mirred egress->ingress: patch 2 changes mirred so that the networking backlog is used for nested mirred ingress actions. ==================== Link: https://lore.kernel.org/r/cover.1674233458.git.dcaratti@redhat.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>
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.
