Karsten Graul says: ==================== net/smc: fix out of bound access in netlink interface Both patches fix possible out-of-bounds reads. The original code expected that snprintf() reads len-1 bytes from source and appends the terminating null, but actually snprintf() first copies len bytes and finally overwrites the last byte with a null. Fix this by using memcpy() and terminating the string afterwards. ==================== Link: https://lore.kernel.org/r/20210112162122.26832-1-kgraul@linux.ibm.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.
