2007-02-26[IPV6]: Adjust inet6_exit() cleanup sequence against inet6_init()Joe Jin1-10/+14
This patch for adjust inet6_exit() to inverse sequence to inet6_init(). At ipv6_init, it first create proc_root/net/dev_snmp6 entry by call ipv6_misc_proc_init(), then call addrconf_init() to create the corresponding device entry at this directory, but at inet6_exit, ipv6_misc_proc_exit() called first, then call addrconf_init().

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau1-1/+0
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2007-01-09[INET]: Fix incorrect "inet_sock->is_icsk" assignment.Paul Moore1-1/+1
The inet_create() and inet6_create() functions incorrectly set the inet_sock->is_icsk field. Both functions assume that the is_icsk field is large enough to hold at least a INET_PROTOSW_ICSK value when it is actually only a single bit. This patch corrects the assignment by doing a boolean comparison whose result will safely fit into a single bit field. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: David S.

2006-12-07[PATCH] Allow NULL pointers in percpu_freeAlan Stern1-4/+2
The patch (as824b) makes percpu_free() ignore NULL arguments, as one would expect for a deallocation routine. (Note that free_percpu is #defined as percpu_free in include/linux/percpu.h.) A few callers are updated to remove now-unneeded tests for NULL. A few other callers already seem to assume that passing a NULL pointer to percpu_free() is okay! The patch also removes an unnecessary NULL check in percpu_depopulate().

This is a revision of the previously submitted patch, which alters the way files are organized and compiled in the following manner: * UDP and UDP-Lite now use separate object files * source file dependencies resolved via header files net/ipv{4,6}/udp_impl.h * order of inclusion files in udp.c/udplite.c adapted accordingly [NET/IPv4]: Support for the UDP-Lite protocol (RFC 3828) This patch adds support for UDP-Lite to the IPv4 stack, provided as an extension to the existing UDPv4 code: * generic routines are all located in net/ipv4/udp.c * UDP-Lite specific routines are in net/ipv4/udplite.c * MIB/statistics support in /proc/net/snmp and /proc/net/udplite * shared API with extensions for partial checksum coverage [NET/IPv6]: Extension for UDP-Lite over IPv6 It extends the existing UDPv6 code base with support for UDP-Lite in the same manner as per UDPv4. In particular, * UDPv6 generic and shared code is in net/ipv6/udp.c * UDP-Litev6 specific extensions are in net/ipv6/udplite.c * MIB/statistics support in /proc/net/snmp6 and /proc/net/udplite6 * support for IPV6_ADDRFORM * aligned the coding style of protocol initialisation with af_inet6.c * made the error handling in udpv6_queue_rcv_skb consistent; to return `-1' on error on all error cases * consolidation of shared code [NET]: UDP-Lite Documentation and basic XFRM/Netfilter support The UDP-Lite patch further provides * API documentation for UDP-Lite * basic xfrm support * basic netfilter support for IPv4 and IPv6 (LOG target) Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: David S.

2006-08-02[IPV6]: Audit all ip6_dst_lookup/ip6_dst_store callsHerbert Xu1-1/+1
The current users of ip6_dst_lookup can be divided into two classes: 1) The caller holds no locks and is in user-context (UDP). 2) The caller does not want to lookup the dst cache at all. The second class covers everyone except UDP because most people do the cache lookup directly before calling ip6_dst_lookup. This patch adds ip6_sk_dst_lookup for the first class. Similarly ip6_dst_store users can be divded into those that need to take the socket dst lock and those that don't. This patch adds __ip6_dst_store for those (everyone except UDP/datagram) that don't need an extra lock. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2006-06-30[IPV6]: Added GSO support for TCPv6Herbert Xu1-2/+0
This patch adds GSO support for IPv6 and TCPv6. This is based on a patch by Ananda Raju <Ananda.Raju@neterion.com>. His original description is: This patch enables TSO over IPv6. Currently Linux network stacks restricts TSO over IPv6 by clearing of the NETIF_F_TSO bit from "dev->features". This patch will remove this restriction. This patch will introduce a new flag NETIF_F_TSO6 which will be used to check whether device supports TSO over IPv6. If device support TSO over IPv6 then we don't clear of NETIF_F_TSO and which will make the TCP layer to create TSO packets. Any device supporting TSO over IPv6 will set NETIF_F_TSO6 flag in "dev->features" along with NETIF_F_TSO. In case when user disables TSO using ethtool, NETIF_F_TSO will get cleared from "dev->features". So even if we have NETIF_F_TSO6 we don't get TSO packets created by TCP layer. SKB_GSO_TCPV4 renamed to SKB_GSO_TCP to make it generic GSO packet. SKB_GSO_UDPV4 renamed to SKB_GSO_UDP as UFO is not a IPv4 feature. UFO is supported over IPv6 also The following table shows there is significant improvement in throughput with normal frames and CPU usage for both normal and jumbo. -------------------------------------------------- | | 1500 | 9600 | | ------------------|-------------------| | | thru CPU | thru CPU | -------------------------------------------------- | TSO OFF | 2.00 5.5% id | 5.66 20.0% id | -------------------------------------------------- | TSO ON | 2.63 78.0 id | 5.67 39.0% id | -------------------------------------------------- Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

We should never touch the dst lock in softirq context. Since inet6_destroy_sock may be called from that context due to the asynchronous nature of sockets, we can't take the lock there. In fact this sk_dst_reset is totally redundant since all IPv6 sockets use inet_sock_destruct as their socket destructor which always cleans up the dst anyway. So the solution is to simply remove the call. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-01-03[NET]: Add a dev_ioctl() fallback to sock_ioctl()Christoph Hellwig1-5/+3
Currently all network protocols need to call dev_ioctl as the default fallback in their ioctl implementations.

2006-01-03[NET]: move struct proto_ops to constEric Dumazet1-3/+3
I noticed that some of 'struct proto_ops' used in the kernel may share a cache line used by locks or other heavily modified data. (default linker alignement is 32 bytes, and L1_CACHE_LINE is 64 or 128 at least) This patch makes sure a 'struct proto_ops' can be declared as const, so that all cpus can share all parts of it without false sharing. This is not mandatory : a driver can still use a read/write structure if it needs to (and eventually a __read_mostly) I made a global stubstitute to change all existing occurences to make them const. This should reduce the possibility of false sharing on SMP, and speedup some socket system calls. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

2006-01-03[IP_SOCKGLUE]: Remove most of the tcp specific callsArnaldo Carvalho de Melo1-0/+1
As DCCP needs to be called in the same spots. Now we have a member in inet_sock (is_icsk), set at sock creation time from struct inet_protosw->flags (if INET_PROTOSW_ICSK is set, like for TCP and DCCP) to see if a struct sock instance is a inet_connection_sock for places like the ones in ip_sockglue.c (v4 and v6) where we previously were looking if sk_type was SOCK_STREAM, that is insufficient because we now use the same code for DCCP, that has sk_type SOCK_DCCP.

A lot of places in there are including major.h for no reason whatsoever. Removed. And yes, it still builds. The history of that stuff is often amusing. E.g. for net/core/sock.c the story looks so, as far as I've been able to reconstruct it: we used to need major.h in net/socket.c circa 1.1.early. In 1.1.13 that need had disappeared, along with register_chrdev(SOCKET_MAJOR, "socket", &net_fops) in sock_init(). Include had not. When 1.2 -> 1.3 reorg of net/* had moved a lot of stuff from net/socket.c to net/core/sock.c, this crap had followed...

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
