SubjectRe: [PATCH net] selftests/net: add definition for SOL_DCCP to fix compilation errors for old libc
From: Alan Maguire <>
Date: Wed, 18 Mar 2020 18:53:21 +0000

> Many systems build/test up-to-date kernels with older libcs, and
> an older glibc (2.17) lacks the definition of SOL_DCCP in
> /usr/include/bits/socket.h (it was added in the 4.6 timeframe).
> Adding the definition to the test program avoids a compilation
> failure that gets in the way of building tools/testing/selftests/net.
> The test itself will work once the definition is added; either
> skipping due to DCCP not being configured in the kernel under test
> or passing, so there are no other more up-to-date glibc dependencies
> here it seems beyond that missing definition.
> Fixes: 11fb60d1089f ("selftests: net: reuseport_addr_any: add DCCP")
