2013-04-29tcp: reset timer after any SYNACK retransmitYuchung Cheng
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.

git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next 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: David S.

2013-04-29sctp: Correct type and usage of sctp_end_cksum()Simon Horman
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.

2013-04-29netfilter: nfnetlink_queue: add skb info attributeFlorian Westphal
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.

2013-04-29netfilter: move skb_gso_segment into nfnetlink_queue moduleFlorian Westphal
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: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2013-04-26SUNRPC: Use gssproxy upcall for server RPCGSS authentication.Simo Sorce
The main advantge of this new upcall mechanism is that it can handle big tickets as seen in Kerberos implementations where tickets carry authorization data like the MS-PAC buffer with AD or the Posix Authorization Data being discussed in IETF on the krbwg working group. The Gssproxy program is used to perform the accept_sec_context call on the kernel's behalf. The code is changed to also pass the input buffer straight to upcall mechanism to avoid allocating and copying many pages as tokens can be as big (potentially more in future) as 64KiB.

2013-04-26SUNRPC: Add RPC based upcall mechanism for RPCGSS authSimo Sorce
This patch implements a sunrpc client to use the services of the gssproxy userspace daemon. In particular it allows to perform calls in user space using an RPC call instead of custom hand-coded upcall/downcall messages. Currently only accept_sec_context is implemented as that is all is needed for the server case. File server modules like NFS and CIFS can use full gssapi services this way, once init_sec_context is also implemented. For the NFS server case this code allow to lift the limit of max 2k krb5 tickets. This limit is prevents legitimate kerberos deployments from using krb5 authentication with the Linux NFS server as they have normally ticket that are many kilobytes large. It will also allow to lift the limitation on the size of the credential set (uid,gid,gids) passed down from user space for users that have very many groups associated. Currently the downcall mechanism used by rpc.svcgssd is limited to around 2k secondary groups of the 65k allowed by kernel structures.

2013-04-25VSOCK: Fix misc device registrationAsias He
When we call vsock_core_init to init VSOCK the second time, vsock_device.minor still points to the old dynamically allocated minor number. misc_register will allocate it for us successfully as if we were asking for a static one. However, when other user call misc_register to allocate a dynamic minor number, it will give the one used by vsock_core_init(), causing this: [ 405.470687] WARNING: at fs/sysfs/dir.c:536 sysfs_add_one+0xcc/0xf0() [ 405.470689] Hardware name: OptiPlex 790 [ 405.470690] sysfs: cannot create duplicate filename '/dev/char/10:54' Always set vsock_device.minor to MISC_DYNAMIC_MINOR before we register.

2013-04-25net: fix address check in rtnl_fdb_delVlad Yasevich
Commit 6681712d67eef14c4ce793561c3231659153a320 vxlan: generalize forwarding tables relaxed the address checks in rtnl_fdb_del() to use is_zero_ether_addr(). This allows users to add multicast addresses using the fdb API. However, the check in rtnl_fdb_del() still uses a more strict is_valid_ether_addr() which rejects multicast addresses. Thus it is possible to add an fdb that can not be later removed. Relax the check in rtnl_fdb_del() as well. Signed-off-by: Vlad Yasevich <vyasevic@redhat.com> Signed-off-by: David S.

2013-04-25NFC: llcp: two bugs in ->getname()Dan Carpenter
The sockaddr_nfc_llcp struct has as hole between ->sa_family and ->dev_idx so I've added a memset() to clear it and prevent an information leak. Also the ->nfc_protocol element wasn't set so I've added that. "uaddr->sa_family" and "llcp_addr->sa_family" are the same thing but it's less confusing to use llcp_addr consistently throughout.

The sockaddr_ax25 struct has a 3 byte hole between ->sax25_call and ->sax25_ndigis. I've added a memset to avoid leaking uninitialized stack data to userspace.

2013-04-25openvswitch: Use parallel_ops genl.Pravin B Shelar
OVS locking was recently changed to have private OVS lock which simplified overall locking. Therefore there is no need to have another global genl lock to protect OVS data structures. Following patch uses of parallel_ops genl family for OVS. This also allows more granual OVS locking using ovs_mutex for protecting OVS data structures, which gives more concurrencey. E.g multiple genl operations OVS_PACKET_CMD_EXECUTE can run in parallel, etc. Signed-off-by: Pravin B Shelar <pshelar@nicira.com> Signed-off-by: David S. Miller <davem@davemloft.net>
