This series is the first step of enabling support for name-based and
wildcard interface hooks in user space. A following series for nftables
depends on this one.
Patch 1 is fallout, noticed when checking for minimal #include
statements in a new source file.
Patch 2 introduces helpers to convert wildcards from user representation
("eth*") to kernel ("eth" len 3) and back. Note that nftables does not
use the serialization part of this since it needs the offsets for
location information.
Patch 3 introduces a helper I wrote for the code in patch 4, but puts it
into a common spot for use in many source files.
Patch 4 finally implements deserialization for NFT_MSG_(NEW|DEL)DEV
payloads. This is a bit of pointless overhead since nftables will use it
in monitor code only, but I didn't want to bypass the standard
integration entirely and fiddle with libmnl in there directly.
Phil Sutter (4):
include: utils.h needs errno.h
utils: Add helpers for interface name wildcards
utils: Introduce nftnl_parse_str_attr()
device: Introduce nftnl_device
