This also fixes a few wrong SPDX license identifiers, where the original
license comment indicates GPL-2.0-only.
This is not done manually, but by running the following script:
---
#!/bin/bash
# Tool to drop license comments, adding SPDX license identifiers, while preserving
# copyright comments. The point is not to manually do this task, but perform some
# hacked up string replacement.
_cp() {
/bin/cp "$@"
}
_cat() {
/bin/cat "$@"
}
in_file() {
local T=$(mktemp)
_cp -f "$1" "$T"
_cat "$T"
rm -f "$T"
}
out_file() {
local T=$(mktemp)
_cat - > "$T"
_cp -f "$T" "$1"
rm -f "$T"
}
join() {
_cat "$@" | awk '{ printf("%s#x#", $0)}'
}
unjoin() {
_cat - | sed 's/#x#/\n/g'
}
files_all() {
git ls-files |
grep -v '\.png$' |
grep -v '^include/linux-private/'
}

Netlink attribute length is defined as u16. It's possible to exceed nla_len when
creating nested attributes. Storing incorrect length due to overflow will cause
a reader to read only a part of nested attribute or skip it entirely.
As a solution cancel the addition of a nested attribute when nla_len size is
exceeded.

- avoid unncessary name change requests
The kernel does not check if the specified IFNAME is different
from the current name. It assumes that if IFNAME and ifindex
are both specified, a name change is requested. Therefore avoid
specyfing IFNAME if ifindex is provided and original and new
name are identical.
- move link building to own function (to allow link add later on)
- error if immutable changes have been made
- better documentation

This patch includes various bugfixes in the packet location parser.
Namely it removes two memory leaks if parsing fails. The parser is
correctly quit if an allocation error occurs and it is no longer
possible to add duplicates.
It removes the possibility to differ between net and host byteorder.
This is better done in the actual classifiers as it makes more sense
to specify this together with the value to compare against.
The patch also extends the API to add new packet locations via
rtnl_pktloc_add().
It introduces reference counting, therefore you now have to give
back packet locations with rtnl_pktloc_put() after looking them up
with rtnl_pktloc_lookup(). But you are allowed to keep using them
if the packet location file has been reread.
The packet location file now also understands "eth", "ip", and
"tcp" for "link", "net", and "transport".
A --list option has been added to nl-pktloc-lookup to list all
packet location definitions
A --u32=VALUE option has been added to let nl-pktloc-lookup print
the definition in iproute2's u32 selector style.
A manual page has been written for nl-pktloc-lookup.
Finally, nl-pktloc-lookup has been made installable.

In order for the interface to become more thread safe, the error
handling was revised to no longer depend on a static errno and
error string buffer.
This patch converts all error paths to return a libnl specific
error code which can be translated to a error message using
nl_geterror(int error). The functions nl_error() and
nl_get_errno() are therefore obsolete.
This change required various sets of function prototypes to be
changed in order to return an error code, the most prominent
are:
struct nl_cache *foo_alloc_cache(...);
changed to:
int foo_alloc_cache(..., struct nl_cache **);
struct nl_msg *foo_build_request(...);
changed to:
int foo_build_request(..., struct nl_msg **);
struct foo *foo_parse(...);
changed to:
int foo_parse(..., struct foo **);
This pretty much only leaves trivial allocation functions to
still return a pointer object which can still return NULL to
signal out of memory.
This change is a serious API and ABI breaker, sorry!
