Given an invalid 'rate' command e.g. 'rate 0' the return value is '1', leading to the following misleading output: - the good case $ echo "rate 100" > /proc/net/pktgen/lo\@0 $ grep "Result:" /proc/net/pktgen/lo\@0 Result: OK: rate=100 - the bad case (before the patch) $ echo "rate 0" > /proc/net/pktgen/lo\@0" -bash: echo: write error: Invalid argument $ grep "Result:" /proc/net/pktgen/lo\@0 Result: No such parameter "ate" - with patch applied $ echo "rate 0" > /proc/net/pktgen/lo\@0 -bash: echo: write error: Invalid argument $ grep "Result:" /proc/net/pktgen/lo\@0 Result: Idle Signed-off-by: Peter Seiderer <ps.report@gmx.net> Reviewed-by: Simon Horman <horms@kernel.org> Link: https://patch.msgid.link/20250219084527.20488-5-ps.report@gmx.net 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 reStructuredText 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.
