[ Upstream commit4970b42d5c] This reverts commite9919a24d3. Nathan reported the new behaviour breaks Android, as Android just add new rules and delete old ones. If we return 0 without adding dup rules, Android will remove the new added rules and causing system to soft-reboot. Fixes:e9919a24d3("fib_rules: return 0 directly if an exactly same rule exists when NLM_F_EXCL not supplied") Reported-by: Nathan Chancellor <natechancellor@gmail.com> Reported-by: Yaro Slav <yaro330@gmail.com> Reported-by: Maciej Żenczykowski <zenczykowski@gmail.com> Signed-off-by: Hangbin Liu <liuhangbin@gmail.com> Reviewed-by: Nathan Chancellor <natechancellor@gmail.com> Tested-by: Nathan Chancellor <natechancellor@gmail.com> Signed-off-by: David S.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
