* ipv4: Disallow non-namespace aware protocols to register.David S. Miller2013-02-053-26/+6
| | | | | | | | | | | All in-tree ipv4 protocol implementations are now namespace aware. Therefore all the run-time checks are superfluous. Reject registry of any non-namespace aware ipv4 protocol. Eventually we'll remove prot->netns_ok and this registry time check as well. Signed-off-by: David S. Miller <davem@davemloft.net>
* l2tp: Make ipv4 protocol handler namespace aware.David S. Miller2013-02-051-6/+10
| | | | | | | | | | | | | The infrastructure is already pretty much entirely there to allow this conversion. The tunnel and session lookups have per-namespace tables, and the ipv4 bind lookup includes the namespace in the lookup key. Set netns_ok in l2tp_ip_protocol. Signed-off-by: David S.

* l2tp: create tunnel sockets in the right namespaceTom Parkin2013-02-051-33/+54
| | | | | | | | | | | | | | When creating unmanaged tunnel sockets we should honour the network namespace passed to l2tp_tunnel_create. Furthermore, unmanaged tunnel sockets should not hold a reference to the network namespace lest they accidentally keep alive a namespace which should otherwise have been released. Unmanaged tunnel sockets now drop their namespace reference via sk_change_net, and are released in a new pernet exit callback, l2tp_exit_net.

* l2tp: prevent tunnel creation on netns mismatchTom Parkin2013-02-051-2/+9
| | | | | | | | | | | | | | l2tp_tunnel_create is passed a pointer to the network namespace for the tunnel, along with an optional file descriptor for the tunnel which may be passed in from userspace via. netlink. In the case where the file descriptor is defined, ensure that the namespace associated with that socket matches the namespace explicitly passed to l2tp_tunnel_create.

The vmxnet3 conflict is about one change in 'net' removing a guarding conditional, whilst in 'net-next' we had a netdev_info() conversion.

| * packet: fix leakage of tx_ring memoryPhil Sutter2013-02-031-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When releasing a packet socket, the routine packet_set_ring() is reused to free rings instead of allocating them. But when calling it for the first time, it fills req->tp_block_nr with the value of rb->pg_vec_len which in the second invocation makes it bail out since req->tp_block_nr is greater zero but req->tp_block_size is zero. This patch solves the problem by passing a zeroed auto-variable to packet_set_ring() upon each invocation from packet_release(). As far as I can tell, this issue exists even since 69e3c75 (net: TX_RING and packet mmap), i.e. the original inclusion of TX ring support into af_packet, but applies only to sockets with both RX and TX ring allocated, which is probably why this was unnoticed all the time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On receiving the SYN-ACK, Fast Open checks icsk_retransmit for SYN retransmission to detect SYN/data drops. But if F-RTO is disabled, icsk_retransmit is reset at step D of tcp_fastretrans_alert() ( under tcp_ack()) before tcp_rcv_fastopen_synack().

For the delay calculation to work, both delay types (latency and delay introduces by rate limitation) have to be handled differently. The latency delay for a packet can overlap with the delay of other packets. The delay introduced by the rate however is separate, and can only start, once all other rate-introduced delays finished. Latency delay is from same distribution for each packet, rate delay depends on the packet size. .: latency delay -: rate delay x: additional delay we have to wait since another packet is currently transmitted .....---- Packet 1 .....xx------ Packet 2 .....------ Packet 3 ^^^^^ latency stacks ^^ rate delay doesn't stack ^^ latency stacks -----> time When a packet is enqueued, we first consider the latency delay. If other packets are already queued, we can reduce the latency delay until the last packet in the queue is send, however the latency delay cannot be <0, since this would mean that the rate is overcommitted. The new reference point is the time at which the last packet will be send. To find the time, when the packet should be send, the rate introduces delay has to be added on top of that.

| * | | l2tp: prevent l2tp_tunnel_delete racing with userspace closeTom Parkin2013-01-292-12/+69

It also caches a pointer to the struct sock for use in the data path and in the netlink interface. While it is safe to use the cached sock pointer in the data path, where the skb references keep the socket alive, it is not safe to use it elsewhere as such access introduces a race with userspace closing the socket. In particular, l2tp_tunnel_delete is prone to oopsing if a multithreaded userspace application closes a socket at the same time as sending a netlink delete command for the tunnel. This patch fixes this oops by forcing l2tp_tunnel_delete to explicitly look up a tunnel socket held by userspace using sockfd_lookup().

In particular consider the following (fictional) scenario to demonstrate this: do: Two SOCK_SEQPACKET-style sockets are opened (S1, S2) S1 is bound to 127.0.0.1, port 1024 [server] S2 is bound to 127.0.0.1, port 1025 [client] listen(2) is invoked on S1 From S2 we call one sendmsg(2) with msg.msg_name and msg.msg_namelen parameters set to the server's address S1, S2 are closed goto do The first pass of this loop passes successful, while the second round fails during binding of S1 (address still in use). What is happening? In the first round, the initial handshake is being done, and, at the time close(2) is called on S1, a non-graceful shutdown is performed via ABORT since in S1's receive queue an unprocessed packet is present, thus stating an error condition. This can be considered as a correct behavior. During close also all bound addresses are freed, thus nothing *must* be active anymore. In reference to RFC2960: After checking the Verification Tag, the receiving endpoint shall remove the association from its record, and shall report the termination to its upper layer. (9.1 Abort of an Association) Also, no half-open states are supported, thus after an ungraceful shutdown, we leave nothing behind. However, this seems not to be happening though. In a real-world scenario, this is exactly where it breaks the lksctp-tools functional test suite, *for instance*: ./test_sockopt test_sockopt.c 1 PASS : getsockopt(SCTP_STATUS) on a socket with no assoc test_sockopt.c 2 PASS : getsockopt(SCTP_STATUS) test_sockopt.c 3 PASS : getsockopt(SCTP_STATUS) with invalid associd test_sockopt.c 4 PASS : getsockopt(SCTP_STATUS) with NULL associd test_sockopt.c 5 BROK : bind: Address already in use The underlying problem is that sctp_endpoint_destroy() hasn't been triggered yet while the next bind attempt is being done. It will be triggered eventually (but too late) by sctp_transport_destroy_rcu() after one RCU grace period: sctp_transport_destroy() sctp_transport_destroy_rcu() ----. sctp_association_put() [*] <--+--> sctp_packet_free() sctp_association_destroy() [...] sctp_endpoint_put() skb->destructor sctp_endpoint_destroy() sctp_wfree() sctp_bind_addr_free() sctp_association_put() [*] Thus, we move out the condition with sctp_association_put() as well as the sctp_packet_free() invocation and the issue can be solved. We also better free the SCTP chunks first before putting the ref of the association. With this patch, the example above (which simulates a similar scenario as in the implementation of this test case) and therefore also the test suite run successfully through. Tested by myself.

Here we take the final step in that cleanup, by doing a wholesale removal of these files. The two step process is used so that the large deletion is decoupled from the git history of files that we still care about. The drivers deleted here all were dependent on the Kconfig setting CONFIG_WAN_ROUTER_DRIVERS. A stub wanrouter.h header (kernel & uapi) are left behind so that drivers/isdn/i4l/isdn_x25iface.c continues to compile, and so that we don't accidentally break userspace that expected these defines.

* | | | wanrouter: completely decouple obsolete code from kernel.Paul Gortmaker2013-01-313-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original suggestion to delete wanrouter started earlier with the mainline commit f0d1b3c2bcc5de8a17af5f2274f7fcde8292b5fc ("net/wanrouter: Deprecate and schedule for removal") in May 2012. More importantly, Dan Carpenter found[1] that the driver had a fundamental breakage introduced back in 2008, with commit 7be6065b39c3 ("netdevice wanrouter: Convert directly reference of netdev->priv"). So we know with certainty that the code hasn't been used by anyone willing to at least take the effort to send an e-mail report of breakage for at least 4 years. This commit does a decouple of the wanrouter subsystem, by going after the Makefile/Kconfig and similar files, so that these mainline files that we are keeping do not have the big wanrouter file/driver deletion commit tied into their history. Once this commit is in place, we then can remove the obsolete cyclomx drivers and similar that have a dependency on CONFIG_WAN_ROUTER_DRIVERS.

Quick grep in drivers/net shows two drivers that have NETIF_F_HW_VLAN_FILTER but not ndo_vlan_rx_add/kill_vid(), but those are false-positives (features are commented out). OTOH two drivers have ndo_vlan_rx_add/kill_vid() implemented but don't advertise NETIF_F_HW_VLAN_FILTER.
