John Fastabend says: ==================== There was a memleak when streaming af_unix sockets were inserted into multiple sockmap slots and/or maps. This is because each insert would call a proto update operatino and these must be allowed to be called multiple times. The streaming af_unix implementation recently added a refcnt to handle a use after free issue, however it introduced a memleak when inserted into multiple maps. This series fixes the memleak, adds a note in the code so we remember that proto updates need to support this. And then we add three tests for each of the slightly different iterations of adding sockets into multiple maps. I kept them as 3 independent test cases here. I have some slight preference for this they could however be a single test, but then you don't get to run them independently which was sort of useful while debugging. ==================== Signed-off-by: Martin KaFai Lau <martin.lau@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.
