5.4.102 backported a lot of stuff that our WireGuard backport already did, in addition to other patches we had, so those patches were removed from that part of the series. In the process other patches were refreshed or reworked to account for upstream changes. This commit involved `update_kernel.sh -v -u 5.4`.

Subject: [PATCH] wireguard: receive: remove dead code from default packet type
|
|
case
|
|
|
|
commit 2b8765c52db24c0fbcc81bac9b5e8390f2c7d3c8 upstream.
|
|
|
|
The situation in which we wind up hitting the default case here
|
|
indicates a major bug in earlier parsing code. It is not a usual thing
|
|
that should ever happen, which means a "friendly" message for it doesn't
|
|
make sense. Rather, replace this with a WARN_ON, just like we do earlier
|
|
in the file for a similar situation, so that somebody sends us a bug
|
|
report and we can fix it.
