Instead of feeding net_secret[] at boot time, defer the init at the point first socket is created. This permits some platforms to use better entropy sources than the ones available at boot time. Signed-off-by:

Lancer FW requires that the first cmd issued by the host-driver be an FLR. So, re-order be_probe() to move be_cmd_function_reset() ahead of be_cmd_fw_init(). Signed-off-by:

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: -

Add support for another ARM member of the R-Car family, R-Car M1A, also known as R8A77781 -- it will share the code with previously added R8A77790. 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:

Userspace can now indicate that it can cope with larger-than-mtu sized packets and packets that have invalid ipv4/tcp checksums. Signed-off-by:

Florian Westphal authored
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 says: ==================== This series of patches is fixing a bug related to multiple control URB submissions (noted by Sarah Sharp), optimizes read and write_mii_word routines and removes socket buffer pool used in the receive path. ==================== Signed-off-by: -
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:

Following patch adds icmp-registration module for ipv6. It allows ipv6 protocol to register icmp_sender which is used for sending ipv6 icmp msgs. This extra layer allows us to kill ipv6 dependency for sending icmp packets. This patch also fixes ip_tunnel compilation problem when ip_tunnel is statically compiled in kernel but ipv6 is module Signed-off-by:

Increase fragmentation hash bucket size to 1024 from old 64 elems. After we increased the frag mem limits commit c2a93660 (net: increase fragment memory usage limits) the hash size of 64 elements is simply too small. Also considering the mem limit is per netns and the hash table is shared for all netns. For the embedded people, note that this increase will change the hash table/array from using approx 1 Kbytes to 16 Kbytes. Signed-off-by:

Testing like this for TP_STATUS_AVAILABLE clearly is a stupid bug since it always returns true. Fix this by only checking for flags where the kernel owns the packet and negate this result, since we also could run into the non-zero status TP_STATUS_WRONG_FORMAT and need to reclaim frames.
