[ Upstream commit440e274da4] In raw6_icmp_error(), raw_v6_match() is called with inet6_iif(skb) passed to both the 'dif' and 'sdif' arguments. This is a copy-paste or typo error, as the last argument should represent the secondary interface index (sdif). This mismatch breaks ICMPv6 error handling for IPv6 raw sockets in VRF (Virtual Routing and Forwarding) environments. When a raw socket is bound to a VRF master device, raw_v6_match() fails to find a match because it is not given the correct sdif value, causing the socket to miss relevant ICMPv6 error notifications. Fix this by properly passing inet6_sdif(skb) as the last argument to raw_v6_match().

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.
