This way we can remove TCP and DCCP specific versions of sk->sk_prot->get_port: both v4 and v6 use inet_csk_get_port sk->sk_prot->hash: inet_hash is directly used, only v6 need a specific version to deal with mapped sockets sk->sk_prot->unhash: both v4 and v6 use inet_hash directly struct inet_connection_sock_af_ops also gets a new member, bind_conflict, so that inet_csk_get_port can find the per family routine. Now only the lookup routines receive as a parameter a struct inet_hashtable. With this we further reuse code, reducing the difference among INET transport protocols. Eventually work has to be done on UDP and SCTP to make them share this infrastructure and get as a bonus inet_diag interfaces so that iproute can be used with these protocols. net-2.6/net/ipv4/inet_hashtables.c: struct proto | +8 struct inet_connection_sock_af_ops | +8 2 structs changed __inet_hash_nolisten | +18 __inet_hash | -210 inet_put_port | +8 inet_bind_bucket_create | +1 __inet_hash_connect | -8 5 functions changed, 27 bytes added, 218 bytes removed, diff: -191 net-2.6/net/core/sock.c: proto_seq_show | +3 1 function changed, 3 bytes added, diff: +3 net-2.6/net/ipv4/inet_connection_sock.c: inet_csk_get_port | +15 1 function changed, 15 bytes added, diff: +15 net-2.6/net/ipv4/tcp.c: tcp_set_state | -7 1 function changed, 7 bytes removed, diff: -7 net-2.6/net/ipv4/tcp_ipv4.c: tcp_v4_get_port | -31 tcp_v4_hash | -48 tcp_v4_destroy_sock | -7 tcp_v4_syn_recv_sock | -2 tcp_unhash | -179 5 functions changed, 267 bytes removed, diff: -267 net-2.6/net/ipv6/inet6_hashtables.c: __inet6_hash | +8 1 function changed, 8 bytes added, diff: +8 net-2.6/net/ipv4/inet_hashtables.c: inet_unhash | +190 inet_hash | +242 2 functions changed, 432 bytes added, diff: +432 vmlinux: 16 functions changed, 485 bytes added, 492 bytes removed, diff: -7 /home/acme/git/net-2.6/net/ipv6/tcp_ipv6.c: tcp_v6_get_port | -31 tcp_v6_hash | -7 tcp_v6_syn_recv_sock | -9 3 functions changed, 47 bytes removed, diff: -47 /home/acme/git/net-2.6/net/dccp/proto.c: dccp_destroy_sock | -7 dccp_unhash | -179 dccp_hash | -49 dccp_set_state | -7 dccp_done | +1 5 functions changed, 1 bytes added, 242 bytes removed, diff: -241 /home/acme/git/net-2.6/net/dccp/ipv4.c: dccp_v4_get_port | -31 dccp_v4_request_recv_sock | -2 2 functions changed, 33 bytes removed, diff: -33 /home/acme/git/net-2.6/net/dccp/ipv6.c: dccp_v6_get_port | -31 dccp_v6_hash | -7 dccp_v6_request_recv_sock | +5 3 functions changed, 5 bytes added, 38 bytes removed, diff: -33 Signed-off-by: -

The bf537 Ethernet MAC driver in the 2007R1.1-RC3 kernel (and the current kernel) do not implement multicast hash filtering. This is a performance problem if you have lots of multicast on your network. This patch plugs the right bits into the multicast hash registers. Signed-off-by:

The documentation regarding synchronisation at the head of the natsemi driver was badly bitrotted so replace it with a general statement about the techniques used which is less likely to bitrot. Also remove the note saying these chips are uncommon - it makes little difference but they were used in a number of laptops and at least one mass market PCI ethernet card. Signed-off-by:

PHY read/write functions can potentially sleep (e.g., a PHY accessed via I2C). The following changes were made to account for this: * Change spin locks to mutex locks * Add a BUG_ON() to phy_read() phy_write() to warn against calling them from an interrupt context. * Use work queue for PHY state machine handling since it can potentially sleep * Change phydev lock from spinlock to mutex Signed-off-by:Nate Case <ncase@xes-inc.com> Acked-by:

The driver should inform the stack when checksum has been performed by the HW when both IP and TCP (or UDP) checksum flags are indicated by HW. Previously, it would also inform the stack when only IP checksum flag was indicated by HW. This can cause data corruption when IP fragments are used. The IP Identification field can wrap around and cause data from new fragments to fill into older fragment slots with same IP Id. The stack would then not perform TCP/UDP checksum (after re-assembly of all fragments) since driver falsely stated it was already calculated. Signed-off-by:

When PCI error recovery was added to cxgb3, a function t3_io_slot_reset() was added. This function can call back into t3_prep_adapter() at any time, so t3_prep_adapter() can no longer be marked __devinit. This patch removes the __devinit annotation from t3_prep_adapter() and all the functions that it calls, which fixes WARNING: drivers/net/cxgb3/built-in.o(.text+0x2427): Section mismatch in reference from the function t3_io_slot_reset() to the function .devinit.text:t3_prep_adapter() Signed-off-by:Roland Dreier <rolandd@cisco.com> Signed-off-by:

Update bonding to version 3.2.4. Signed-off-by:

Jay Vosburgh authored
The ARP monitor functions currently acquire RTNL when performing failover operations, but do so incorrectly (out of order). This causes various warnings from might_sleep. The ARP monitor isn't supported for any of the bonding modes that actually require RTNL, so it is safe to not hold RTNL when failing over in the ARP monitor. Signed-off-by:

I've seen reports of invalid stats in /proc/net/dev for bonding interfaces, and found it's a pretty easy problem to reproduce. Since the current code zeros the bonding stats when a read is requested and a pointer to that data is returned to the caller we cannot guarantee that the caller has completely accessed the data before a successive call to request the stats zeroes the stats again. This patch creates a new stack variable to keep track of the updated stats and copies the data from that variable into the bonding stats structure. This ensures that the value for any of the bonding stats should not incorrectly return zero for any of the bonding statistics. This does use more stack space and require an extra memcpy, but it seems like a fair trade-off for consistently correct bonding statistics. Signed-off-by:

This patch eliminates a problem (reported by lockdep) in the bond_set_multicast_list function. It first reduces the locking on bond->lock to a simple read_lock, and second, adds netif_tx locking around the bonding mc_list manipulations that occur outside of the set_multicast_list function. The original problem was related to IPv6 addrconf activity. Signed-off-by:

This is Thiemo's patch. ----- Forwarded message from Thiemo Seufer <ths@networkno.de> ----- From: Thiemo Seufer <ths@networkno.de> Date: Sat, 17 Nov 2007 22:29:13 +0000 To: netdev@vger.kernel.org Cc: linux-mips@linux-mips.org, ralf@linux-mips.org Subject: [PATCH, REPOST] Fix/Rewrite of the mipsnet driver Content-Type: text/plain; charset=us-ascii Hello All, currently the mipsnet driver fails after transmitting a number of packages because SKBs are allocated but never freed. I fixed that and coudn't refrain from removing the most egregious warts. - mipsnet.h folded into mipsnet.c, as it doesn't provide any useful external interface. - Free SKB after transmission. - Call free_irq in mipsnet_close, to balance the request_irq in mipsnet_open. - Removed duplicate read of rxDataCount. - Some identifiers are now less verbose. - Removed dead and/or unnecessarily complex code. - Code formatting fixes. Tested on Qemu's mipssim emulation, with this patch it can boot a Debian NFSroot. Thiemo Signed-off-by:
