linux-toradex.git/include/uapi/linux/packet_diag.h, branch v3.15-rc8 Linux kernel for Apalis and Colibri modules diag: warn about missing first netlink attribute 2013-11-28T23:16:43+00:00 Nicolas Dichtel nicolas.dichtel@6wind.com 2013-11-28T17:31:05+00:00 31e20bad8d5871c6f8673c28ea26ab7a0e520086 The first netlink attribute (value 0) must always be defined as none/unspec. This is correctly done in inet_diag.h, but other diag interfaces are wrong. Because we cannot change an existing API, I add a comment to point the mistake and avoid to propagate it in a new diag API in the future.

The first netlink attribute (value 0) must always be defined as none/unspec.
This is correctly done in inet_diag.h, but other diag interfaces are wrong.

Because we cannot change an existing API, I add a comment to point the mistake
and avoid to propagate it in a new diag API in the future.
