Nikolay Aleksandrov says: ==================== net: bridge: mcast: add and enforce query interval minimum This set adds and enforces 1 second minimum value for bridge multicast query and startup query intervals in order to avoid rearming the timers too often which could lock and crash the host. I doubt anyone is using such low values or anything lower than 1 second, so it seems like a good minimum. In order to be compatible if the value is lower then it is overwritten and a log message is emitted, since we can't return an error at this point. Eric, I looked for the syzbot reports in its dashboard but couldn't find them so I've added you as the reporter. I've prepared a global bridge igmp rate limiting patch but wasn't sure if it's ok for -net. It adds a static limit of 32k packets per second, I plan to send it for net-next with added drop counters for each bridge so it can be easily debugged.

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.
