2009-10-13udp: Fix udp_poll() and ioctl()Eric Dumazet
udp_poll() can in some circumstances drop frames with incorrect checksums. Problem is we now have to lock the socket while dropping frames, or risk sk_forward corruption. This bug is present since commit 95766fff6b9a78d1 ([UDP]: Add memory accounting.) While we are at it, we can correct ioctl(SIOCINQ) to also drop bad frames.

2009-10-13tcp: fix tcp_defer_accept to consider the timeoutWilly Tarreau
I was trying to use TCP_DEFER_ACCEPT and noticed that if the client does not talk, the connection is never accepted and remains in SYN_RECV state until the retransmits expire, where it finally is deleted. This is bad when some firewall such as netfilter sits between the client and the server because the firewall sees the connection in ESTABLISHED state while the server will finally silently drop it without sending an RST. This behaviour contradicts the man page which says it should wait only for some time : TCP_DEFER_ACCEPT (since Linux 2.4) Allows a listener to be awakened only when data arrives on the socket. Takes an integer value (seconds), this can bound the maximum number of attempts TCP will make to complete the connection. This option should not be used in code intended to be portable. Also, looking at ipv4/tcp.c, a retransmit counter is correctly computed : case TCP_DEFER_ACCEPT: icsk->icsk_accept_queue.rskq_defer_accept = 0; if (val > 0) { /* Translate value in seconds to number of * retransmits */ while (icsk->icsk_accept_queue.rskq_defer_accept < 32 && val > ((TCP_TIMEOUT_INIT / HZ) << icsk->icsk_accept_queue.rskq_defer_accept)) icsk->icsk_accept_queue.rskq_defer_accept++; icsk->icsk_accept_queue.rskq_defer_accept++; } break; ==> rskq_defer_accept is used as a counter of retransmits. But in tcp_minisocks.c, this counter is only checked. And in fact, I have found no location which updates it. So I think that what was intended was to decrease it in tcp_minisocks whenever it is checked, which the trivial patch below does. Signed-off-by: Willy Tarreau <w@1wt.eu> Signed-off-by: David S.

2009-10-12net: Introduce recvmmsg socket syscallArnaldo Carvalho de Melo
Meaning receive multiple messages, reducing the number of syscalls and net stack entry/exit operations. Next patches will introduce mechanisms where protocols that want to optimize this operation will provide an unlocked_recvmsg operation. This takes into account comments made by: . Paul Moore: sock_recvmsg is called only for the first datagram, sock_recvmsg_nosec is used for the rest. . Caitlin Bestler: recvmmsg now has a struct timespec timeout, that works in the same fashion as the ppoll one. If the underlying protocol returns a datagram with MSG_OOB set, this will make recvmmsg return right away with as many datagrams (+ the OOB one) it has received so far. . Rémi Denis-Courmont & Steven Whitehouse: If we receive N < vlen datagrams and then recvmsg returns an error, recvmmsg will return the successfully received datagrams, store the error and return it in the next call. This paves the way for a subsequent optimization, sk_prot->unlocked_recvmsg, where we will be able to acquire the lock only at batch start and end, not at every underlying recvmsg call.

2009-10-12net: Generalize socket rx gap / receive queue overflow cmsgNeil Horman
Create a new socket level option to report number of queue overflows Recently I augmented the AF_PACKET protocol to report the number of frames lost on the socket receive queue between any two enqueued frames. This value was exported via a SOL_PACKET level cmsg. AFter I completed that work it was requested that this feature be generalized so that any datagram oriented socket could make use of this option. As such I've created this patch, It creates a new SOL_SOCKET level option called SO_RXQ_OVFL, which when enabled exports a SOL_SOCKET level cmsg that reports the nubmer of times the sk_receive_queue overflowed between any two given frames. It also augments the AF_PACKET protocol to take advantage of this new feature (as it previously did not touch sk->sk_drops, which this patch uses to record the overflow count). Tested successfully by me. Notes: 1) Unlike my previous patch, this patch simply records the sk_drops value, which is not a number of drops between packets, but rather a total number of drops. Deltas must be computed in user space. 2) While this patch currently works with datagram oriented protocols, it will also be accepted by non-datagram oriented protocols. I'm not sure if thats agreeable to everyone, but my argument in favor of doing so is that, for those protocols which aren't applicable to this option, sk_drops will always be zero, and reporting no drops on a receive queue that isn't used for those non-participating protocols seems reasonable to me. This also saves us having to code in a per-protocol opt in mechanism. 3) This applies cleanly to net-next assuming that commit 977750076d98c7ff6cbda51858bb5a5894a9d9ab (my af packet cmsg patch) is reverted Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2009-10-12mac80211: document ieee80211_rx() context requirementJohannes Berg
ieee80211_rx() must be called with softirqs disabled since the networking stack requires this for netif_rx() and some code in mac80211 can assume that it can not be processing its own tasklet and this call at the same time. It may be possible to remove this requirement after a careful audit of mac80211 and doing any needed locking improvements in it along with disabling softirqs around netif_rx(). An alternative might be to push all packet processing to process context in mac80211, instead of to the tasklet, and add other synchronisation.

2009-10-12mac80211: fix ibss raceJohannes Berg
When a scan completes, we call ieee80211_sta_find_ibss(), which is also called from other places. When the scan was done in software, there's no problem as both run from the single-threaded mac80211 workqueue and are thus serialised against each other, but with hardware scan the completion can be in a different context and race against callers of this function from the workqueue (e.g. due to beacon RX). So instead of calling ieee80211_sta_find_ibss() directly, just arm the timer and have it fire, scheduling the work, which will invoke ieee80211_sta_find_ibss() (if that is appropriate in the current state).

2009-10-07udp: dynamically size hash tables at boot timeEric Dumazet
UDP_HTABLE_SIZE was initialy defined to 128, which is a bit small for several setups. 4000 active UDP sockets -> 32 sockets per chain in average. An incoming frame has to lookup all sockets to find best match, so long chains hurt latency. Instead of a fixed size hash table that cant be perfect for every needs, let UDP stack choose its table size at boot time like tcp/ip route, using alloc_large_system_hash() helper Add an optional boot parameter, uhash_entries=x so that an admin can force a size between 256 and 65536 if needed, like thash_entries and rhash_entries. dmesg logs two new lines : [ 0.647039] UDP hash table entries: 512 (order: 0, 4096 bytes) [ 0.647099] UDP Lite hash table entries: 512 (order: 0, 4096 bytes) Maximal size on 64bit arches would be 65536 slots, ie 1 MBytes for non debugging spinlocks.

2009-10-07dccp ccid-2: Overhaul CCID naming convention 1/2Gerrit Renker
This patch starts a less problematic naming convention for CCID structs. The old naming convention used 'hc{tx,rx}->ccid?hc{tx,rx}->...' as recurring prefixes, which made the code * hard to write (not easy to fit into 80 characters); * hard to read (most of the space is occupied by prefixes). The new naming scheme: * struct entries for the TX socket are prefixed by 'tx_'; * and those for the RX socket are prefixed by 'rx_'. The identifiers then remain distinguishable when grep-ing through the tree: (a) RX/TX sockets are distinguished by the naming scheme, (b) individual CCIDs are distinguished by filename (ccid{2,3,4}.{c,h}).

Additionally, the transmit side must check that the station we're sending a frame to is actually on the interface we're transmitting on, and not transmit packets to functions that live on other interfaces, so validate that as well.

A selective reset may also be useful for debugging or diagnostics. This adds a separate reset operation which takes flags indicating the components to be reset. Drivers are allowed to reset only a subset of those requested, and must indicate the actual subset. This allows the use of generic component masks and some future expansion.

2009-10-07ipv6 sit: 6rd (IPv6 Rapid Deployment) Support.YOSHIFUJI Hideaki / 吉藤英明
IPv6 Rapid Deployment (6rd; draft-ietf-softwire-ipv6-6rd) builds upon mechanisms of 6to4 (RFC3056) to enable a service provider to rapidly deploy IPv6 unicast service to IPv4 sites to which it provides customer premise equipment. Like 6to4, it utilizes stateless IPv6 in IPv4 encapsulation in order to transit IPv4-only network infrastructure. Unlike 6to4, a 6rd service provider uses an IPv6 prefix of its own in place of the fixed 6to4 prefix. With this option enabled, the SIT driver offers 6rd functionality by providing additional ioctl API to configure the IPv6 Prefix for in stead of static 2002::/16 for 6to4.

2009-10-07add vif using local interface index instead of IPIlia K
When routing daemon wants to enable forwarding of multicast traffic it performs something like: struct vifctl vc = { .vifc_vifi = 1, .vifc_flags = 0, .vifc_threshold = 1, .vifc_rate_limit = 0, .vifc_lcl_addr = ip, /* <--- ip address of physical interface, e.g. eth0 */ .vifc_rmt_addr.s_addr = htonl(INADDR_ANY), }; setsockopt(fd, IPPROTO_IP, MRT_ADD_VIF, &vc, sizeof(vc)); This leads (in the kernel) to calling vif_add() function call which search the (physical) device using assigned IP address: dev = ip_dev_find(net, vifc->vifc_lcl_addr.s_addr); The current API (struct vifctl) does not allow to specify an interface other way than using it's IP, and if there are more than a single interface with specified IP only the first one will be found. The attached patch (against 2.6.30.4) allows to specify an interface by its index, instead of IP address: struct vifctl vc = { .vifc_vifi = 1, .vifc_flags = VIFF_USE_IFINDEX, /* NEW */ .vifc_threshold = 1, .vifc_rate_limit = 0, .vifc_lcl_ifindex = if_nametoindex("eth0"), /* NEW */ .vifc_rmt_addr.s_addr = htonl(INADDR_ANY), }; setsockopt(fd, IPPROTO_IP, MRT_ADD_VIF, &vc, sizeof(vc)); Signed-off-by: Ilia K. <mail4ilia@gmail.com> === modified file 'include/linux/mroute.h' Signed-off-by: David S.
