John W. Linville says: ==================== A few more stragglers intended for 3.10... For the Bluetooth bits, Gustavo says: "A few more patches intended for 3.10, the most important one is the support in btusb for fw loading for the Intel Bluetooth device. Other than that we have only fixes and clean ups." For the iwlwifi bits, Johannes says: "Here are a few more changes for the 3.10 stream, some bugfixes, adjustments to some powersave parameters and a new device ID." For the NFC bits, Samuel says: "This pull request includes Marcel's Kconfig dependency fix on top of the LLCP code move to net/nfc." On top of that...Yogesh Ashok Powar provides a few PCI-related mwifiex updates, Hauke Mehrtens provides a small ssb feature for spurious tone avoidance on a specific chip, and Larry Finger provides a small rtlwifi fix related to avoiding false detection of AP loss. ==================== Signed-off-by:

Newer firmware can post CPL_SGE_EGR_UPDATE message encapsulated in a CPL_FW4_MSG as follows flit0 rss_header (if DropRSS == 0 in IQ context) flit1 CPL_FW4_MSG cpl flit2 rss_header w/opcode CPL_SGE_EGR_UPDATE flit3 CPL_SGE_EGR_UPDATE cpl So FW4_MSG CPLs with a newly created type of FW_TYPE_RSSCPL have the CPL_SGE_EGR_UPDATE CPL message in flit 2 of the FW4_MSG. Firmware can still post regular CPL_SGE_EGR_UPDATE messages, so the drivers need to handle both. This patch also writes a new parameter to firmware requesting encapsulated EGR_UPDATE. This allows firmware with this support to not break older drivers. Signed-off-by:

Linux immediately returns SYNACK on (spurious) SYN retransmits, but keeps the SYNACK timer running independently. 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.

Samuel Ortiz <sameo@linux.intel.com> says: "With this one we have: - One patch for moving the LLCP code into net/nfc. 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>

Pablo Neira Ayuso says: ==================== The following patchset contains relevant updates for the Netfilter tree, they are: * Enhancements for ipset: Add the counter extension for sets, this information can be used from the iptables set match, to change the matching behaviour. 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: -

Change the type of the crc32 parameter of sctp_end_cksum() from __be32 to __u32 to reflect that fact that it is passed to cpu_to_le32(). There are five in-tree users of sctp_end_cksum(). The following four had warnings flagged by sparse which are no longer present with this change. net/netfilter/ipvs/ip_vs_proto_sctp.c:sctp_nat_csum() net/netfilter/ipvs/ip_vs_proto_sctp.c:sctp_csum_check() net/sctp/input.c:sctp_rcv_checksum() net/sctp/output.c:sctp_packet_transmit() The fifth user is net/netfilter/nf_nat_proto_sctp.c:sctp_manip_pkt(). It has been updated to pass a __u32 instead of a __be32, the value in question was already calculated in cpu byte-order. net/netfilter/nf_nat_proto_sctp.c:sctp_manip_pkt() has also been updated to assign the return value of sctp_end_cksum() directly to a variable of type __le32, matching the type of the return value. Previously the return value was assigned to a variable of type __be32 and then that variable was finally assigned to another variable of type __le32. Problems flagged by sparse. Compile and sparse tested only. Signed-off-by:

Once we allow userspace to receive gso/gro packets, userspace needs to be able to determine when checksums appear to be broken, but are not. NFQA_SKB_CSUMNOTREADY means 'checksums will be fixed in kernel later, pretend they are ok'. NFQA_SKB_GSO could be used for statistics, or to determine when packet size exceeds mtu. Signed-off-by:

skb_gso_segment is expensive, so it would be nice if we could avoid it in the future. 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:

Fixed: warning: cast from pointer to integer of different size The Hyper-V hosts always use 64 bit request id. The guests can have 32 or 64 bit pointers which equal to the ulong type size. So we cast it to ulong type. And, assigning 32bit integer to 64 bit variable works fine. The VMBus returns the same id in the completion packet. But the value has no effect on the host side.

Petko Manolov authored
Pegasus driver used single callback for sync and async control URBs. Special flags were employed to distinguish between both, but due to flawed logic it didn't always work. As a result of this change [get|set]_registers() are now much simpler. Async write is also leaner and does not use single, statically allocated memory for usb_ctrlrequest, which is another potential race when asynchronously submitting URBs. Signed-off-by:
