2013-11-03net/hsr: Add support for the High-availability Seamless Redundancy protocol ↵Arvid Brodin15-0/+2403
(HSRv0) High-availability Seamless Redundancy ("HSR") provides instant failover redundancy for Ethernet networks. It requires a special network topology where all nodes are connected in a ring (each node having two physical network interfaces). It is suited for applications that demand high availability and very short reaction time. HSR acts on the Ethernet layer, using a registered Ethernet protocol type to send special HSR frames in both directions over the ring. The driver creates virtual network interfaces that can be used just like any ordinary Linux network interface, for IP/TCP/UDP traffic etc. All nodes in the network ring must be HSR capable. This code is a "best effort" to comply with the HSR standard as described in IEC 62439-3:2010 (HSRv0). Signed-off-by: Arvid Brodin <arvid.brodin@xdin.com> Signed-off-by: David S.

2013-11-03net: extend net_device allocation to vmalloc()Eric Dumazet4-11/+24
Joby Poriyath provided a xen-netback patch to reduce the size of xenvif structure as some netdev allocation could fail under memory pressure/fragmentation. This patch is handling the problem at the core level, allowing any netdev structures to use vmalloc() if kmalloc() failed. As vmalloc() adds overhead on a critical network path, add __GFP_REPEAT to kzalloc() flags to do this fallback only when really needed.

2013-11-03net: sctp: fix and consolidate SCTP checksumming codeDaniel Borkmann2-45/+20
This fixes an outstanding bug found through IPVS, where SCTP packets with skb->data_len > 0 (non-linearized) and empty frag_list, but data accumulated in frags[] member, are forwarded with incorrect checksum letting SCTP initial handshake fail on some systems. Linearizing each SCTP skb in IPVS to prevent that would not be a good solution as this leads to an additional and unnecessary performance penalty on the load-balancer itself for no good reason (as we actually only want to update the checksum, and can do that in a different/better way presented here). The actual problem is elsewhere, namely, that SCTP's checksumming in sctp_compute_cksum() does not take frags[] into account like skb_checksum() does. So while we are fixing this up, we better reuse the existing code that we have anyway in __skb_checksum() and use it for walking through the data doing checksumming. This will not only fix this issue, but also consolidates some SCTP code with core sk_buff code, bringing it closer together and removing respectively avoiding reimplementation of skb_checksum() for no good reason. As crc32c() can use hardware implementation within the crypto layer, we leave that intact (it wraps around / falls back to e.g. slice-by-8 algorithm in __crc32c_le() otherwise); plus use the __crc32c_le_combine() combinator for crc32c blocks. Also, we remove all other SCTP checksumming code, so that we only have to use sctp_compute_cksum() from now on; for doing that, we need to transform SCTP checkumming in output path slightly, and can leave the rest intact.

2013-11-03net: skb_checksum: allow custom update/combine for walking skbDaniel Borkmann3-13/+37
Currently, skb_checksum walks over 1) linearized, 2) frags[], and 3) frag_list data and calculats the one's complement, a 32 bit result suitable for feeding into itself or csum_tcpudp_magic(), but unsuitable for SCTP as we're calculating CRC32c there. Hence, in order to not re-implement the very same function in SCTP (and maybe other protocols) over and over again, use an update() + combine() callback internally to allow for walking over the skb with different algorithms.

2013-11-03lib: crc32: add functionality to combine two crc32{, c}s in GF(2)Daniel Borkmann2-0/+121
This patch adds a combinator to merge two or more crc32{,c}s into a new one. This is useful for checksum computations of fragmented skbs that use crc32/crc32c as checksums. The arithmetics for combining both in the GF(2) was taken and slightly modified from zlib. Only passing two crcs is insufficient as two crcs and the length of the second piece is needed for merging. The code is made generic, so that only polynomials need to be passed for crc32_le resp. crc32c_le.

Bjørn Mork says: ==================== cdc_ncm: many small and mostly trivial fixes This series ended up longer than expected, and it is still not complete. There is more to come when time allows... Most changes are trivial. Notable non-trivial changes are - removed filtering of identical speed notifications - tx_max calulation is changed to count the pad byte if necessary, and respect the device limit as an absolute upper limit even if it is too low according to the spec - remove the bug preventing SET_MAX_DATAGRAM_SIZE from having any effect - drop the pad-to-max if ZLPs are enabled - the driver specific VERSION is dropped - dev->hard_mtu is set to tx_max instead of max_datagram_size causing usbnet to calculate the qlen based on the real max size of tx skbs This series has been tested, along with the previously posted cdc_mbim series, on the NCM and MBIM devices I have: - Ericsson F5521gw (NCM) - Huawei E367 (MBIM) - D-Link DWM-156 A7 (MBIM w/ too low dwNtb{In,Out}MaxSize bug) - Sierra Wireless MC7710 (MBIM w/ ZLP and CDC Union bugs) Apart from the D-Link modem dropping a lot less oversized frames with the fix dedicated to it, there are no end user noticable functional changes as a result of this series. But all the non-trivial changes I listed above are of course detectable by users looking at that specific area (except maybe the removed speed notification, which requires a device sending duplicates to be noticable - I don't have any such device). ==================== Signed-off-by: David S.

There are MBIM devices out there reporting dwNtbInMaxSize=2048 dwNtbOutMaxSize=2048 and since the spec require a datagram max size of at least 2048, this means that a full sized datagram will never fit. Still, sending larger NTBs than the device supports is not going to help. We do not have any other options than either a) refusing to bindi, or b) respect the insanely low value.

We can avoid the costly division for the common case where we pad the frame to tx_max size as long as we ensure that tx_max is either the device specified dwNtbOutMaxSize or not a multiplum of wMaxPacketSize. Using the preconverted 'maxpacket' field avoids converting wMaxPacketSize to CPU endianness for every transmitted frame And since we only will hit the one byte padding rule for short frames, we can drop testing the skb for tailroom. The change means that tx_max now represents the real maximum skb size, enabling us to allocate the correct size instead of always making room for one extra byte.

A number of devices in the wild have turned out to require ZLPs. Even if this is a spec violation, our priority is to make any device work as good as possible. Devices needing ZLPs will fail to receive any full sized frame we send. On the other hand, devices which do not need the ZLP will still work if we send them. This gives us no other option than sending ZLPs by default. This will prevent devices conforming to the spec from making the optimizations which are possible without ZLPs.

2013-11-02net: cdc_mbim: handle IPv6 Neigbor SolicitationsBjørn Mork1-0/+58
MBIM is a point-to-point protocol transporting raw IP packets with no L2 headers. Only IPv4 and IPv6 are supported. ARP in particular is not, which is quite logical given the lack of L2 headers. The driver still emulates an ethernet interface, dropping all unsupported protocols, and avoiding neigbour resolving by setting the IFF_NOARP flag. The MBIM specification does not explicitly forbid IPv6 Neighbor Discovery, and it seems the other OS support will respond to Neighbor Solicitations on MBIM links. There are therefore buggy devices out there, which despite the pointlessness, still require Neighbor Discovery for IPv6 over MBIM. This is incompatible with the IFF_NOARP flag which disables both ARP and ND. We cannot support ARP in any case, so we have to keep that flag. This patch implements a workaround for the buggy devices, letting the driver respond directly to Neighbor Solicitations from the device. This is not optimal, but will have minimal effect on any sane device.
