Merge branch 'netlink_ext_ACK'
Johannes Berg says:
====================
netlink extended ACK reporting
Changes since v4:
* use __NLMSGERR_ATTR_MAX instead of NUM_NLMSGERR_ATTRS
Changes since v3:
* Add NLM_F_CAPPED and NLM_F_ACK_TLVS flags, to allow entirely
stateless parsing of the ACK messages by looking at the new
flags. Need to check NLM_F_ACK_TLVS first, since capping can
be done in kernels before this patchset without setting the
flag.
* Remove "missing_attr" functionality - this can obviously be
added back rather easily, but I'd rather have more discussion
about the nesting problem there.
* Improve documentation of NLMSGERR_ATTR_OFFS
* Improve message structure documentation, documenting that the
request message is always capped for success cases
* fix nlmsg_len of the outer message by calling nlmsg_end()
* fix memcpy() of the request in success cases, going back to
the original code that I'd changed before due to the payload
adjustments that I reverted when introducing tlvlen
Changes since v2:
* add NUM_NLMSGERR_ATTRS, NLMSGERR_ATTR_MAX
* fix cookie length to 20 (sha-1 length)
* move struct members for cookie to patch 3 where they should be
* another cleanup suggested by David Ahern
Changes since v1:
* credit Pablo and Jamal
* incorporate suggestion from David Ahern
* fix compilation in decnet
