Linux kernel source tree
73cb11933c
Cited commit mistakenly copied provided option to 'val' instead of to
'mfc':
```
- if (copy_from_user(&mfc, optval, sizeof(mfc))) {
+ if (copy_from_sockptr(&val, optval, sizeof(val))) {
```
Fix this by copying the option to 'mfc'.
selftest router_multicast.sh before:
$ ./router_multicast.sh
smcroutectl: Unknown or malformed IPC message 'a' from client.
smcroutectl: failed removing multicast route, does not exist.
TEST: mcast IPv4 [FAIL]

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.
