Subject: [PATCH] wireguard: socket: remove bogus __be32 annotation
|
||
|
|
|
||
|
|
commit 7f57bd8dc22de35ddd895294aa554003e4f19a72 upstream.
|
||
|
|
|
||
|
|
The endpoint->src_if4 has nothing to do with fixed-endian numbers; remove
|
||
|
|
the bogus annotation.
|
||
|
|
|
||
|
|
This was introduced in
|
||
|
|
https://git.zx2c4.com/wireguard-monolithic-historical/commit?id=14e7d0a499a676ec55176c0de2f9fcbd34074a82
|
||
|
|
in the historical WireGuard repo because the old code used to
|
||
|
|
zero-initialize multiple members as follows:
|
||
|
|
|
||
|
|
endpoint->src4.s_addr = endpoint->src_if4 = fl.saddr = 0;
|
||
|
|
|
||
|
|
Because fl.saddr is fixed-endian and an assignment returns a value with the
|
||
|
|
type of its left operand, this meant that sparse detected an assignment
|
||
|
|
between values of different endianness.
|
||
|
|
|
||
|
|
Since then, this assignment was already split up into separate statements;
|
||
|
|
just the cast survived.
