It fixes a build annoyance reported by Dave Miller caused by the fact that the LLCP code object targets are not in the same directory as the Makefile trying to build them is. It prevents us from doing e.g. make net/nfc/llcp/sock.o Moving the LLCP code into net/nfc and not making it optional anymore makes sense as LLCP is a fundamental piece of the NFC specifications and thus should be in the core NFC directory. - One patch that fixes the missing dependency against RFKILL. Without it NFC fails to properly build when it's builtin and CONFIG_RFKILL=m." Signed-off-by: John W. Linville <linville@tuxdriver.com>

This is further reflected in the Read Local Extended Features HCI command also not being available for LE-only controllers. In other words, host-side LE support is implicit for single-mode LE controllers and doesn't have explicit HCI-level enablement. This patch ensures that the LE setting is always exposed as enabled through mgmt and returns a "rejected" response if user space tries to toggle the setting. The patch also ensures that Write LE Host Supported is never sent for LE-only controllers.

Therefore, the parameter type should be declared const. This also allows passing already const parameters to these APIs which previously would have generated a compiler warning.

Thus the timer may fire right after the SYNACK retransmit and causes a SYN-SYNACK cross-fire burst. Adopt the fast retransmit/recovery idea in established state by re-arming the SYNACK timer after the fast (SYNACK) retransmit. The timer may fire late up to 500ms due to the current SYNACK timer wheel, but it's OK to be conservative when network is congested. Eric's new listener design should address this issue.

Jozsef required to add the extension infrastructure and moved the existing timeout support upon it. This also includes a change in net/sched/em_ipset to adapt it to the new extension structure. * Enhancements for performance boosting in nfnetlink_queue: Add new configuration flags that allows user-space to receive big packets (GRO) and to disable checksumming calculation. This were proposed by Eric Dumazet during the Netfilter Workshop 2013 in Copenhagen. Florian Westphal was kind enough to find the time to materialize the proposal. * A sparse fix from Simon, he noticed it in the SCTP NAT helper, the fix required a change in the interface of sctp_end_cksum. ==================== Signed-off-by: David S.

However, userspace needs to be prepared to receive larger-than-mtu-packets (which will also have incorrect l3/l4 checksums), so we cannot simply remove it. The plan is to add a per-queue feature flag that userspace can set when binding the queue. The problem is that in nf_queue, we only have a queue number, not the queue context/configuration settings. This patch should have no impact other than the skb_gso_segment call now being in a function that has access to the queue config data. A new size attribute in nf_queue_entry is needed so nfnetlink_queue can duplicate the entry of the gso skb when segmenting the skb while also copying the route key. The follow up patch adds switch to disable skb_gso_segment when queue config says so. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
