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 ==================== Signed-off-by: David S.
