2008-04-30tcp: Overflow bug in VegasLachlan Andrew
From: Lachlan Andrew <lachlan.andrew@gmail.com> There is an overflow bug in net/ipv4/tcp_vegas.c for large BDPs (e.g. 400Mbit/s, 400ms). The multiplication (old_wnd * vegas->baseRTT) << V_PARAM_SHIFT overflows a u32. [ Fix tcp_veno.c too, it has similar calculations. -DaveM ] Signed-off-by: David S. Miller <davem@davemloft.net>
2008-04-29[IPv4] UFO: prevent generation of chained skb destined to UFO deviceKostya B
Problem: ip_append_data() could wrongly generate a chained skb for devices which support UFO. When sk_write_queue is not empty (e.g. MSG_MORE), __instead__ of appending data into the next nr_frag of the queued skb, a new chained skb is created. I would normally assume UFO device should get data in nr_frags and not in frag_list. Later the udp4_hwcsum_outgoing() resets csum to NONE and skb_gso_segment() has oops. Proposal: 1. Even length is less than mtu, employ ip_ufo_append_data() and append data to the __existed__ skb in the sk_write_queue. 2. ip_ufo_append_data() is fixed due to a wrong manipulation of peek-ing and later enqueue-ing of the same skb. Now, enqueuing is always performed, because on error the further ip_flush_pending_frames() would release the queued skb.

2008-04-29netfilter: nf_conntrack: padding breaks conntrack hash on ARMPhilip Craig
commit 0794935e "[NETFILTER]: nf_conntrack: optimize hash_conntrack()" results in ARM platforms hashing uninitialised padding. This padding doesn't exist on other architectures. Fix this by replacing NF_CT_TUPLE_U_BLANK() with memset() to ensure everything is initialised. There were only 4 bytes that NF_CT_TUPLE_U_BLANK() wasn't clearing anyway (or 12 bytes on ARM).

1) added missing "__user" for kgsr and kgf pointers 2) verify read for only GROUP_FILTER_SIZE(0). The group_filter structure definition (via RFC) includes space for one source in the source list array, but that source need not be present. So, sizeof(group_filter) > GROUP_FILTER_SIZE(0).

2008-04-29bridge: kernel panic when unloading bridge moduleBodo Stroesser
There is a race condition when unloading bridge and netfilter. The problem happens if __fake_rtable is in use by a skb coming in, while someone starts to unload bridge.ko. br_netfilter_fini() is called at the beginning of unload in br_deinit() while skbs still are being forwarded and transferred to local ip stack. Thus there is a possibility of the __fake_rtable pointer not being removed in a skb that goes up to ip stack. This results in a kernel panic, as ip_rcv() calls the input-function of __fake_rtable, which is NULL. Moving the call of br_netfilter_fini() to the end of br_deinit() solves the problem.

AFAICT, it should ask for 'diff' instead of 'diff - skb_tailroom(e->skb)'. Because the resulting sk_buff has not enough space to support the skb_put(skb, diff) call a few lines later, this results in the call to skb_over_panic(). The patch below asks for allocation of a copy with enough space for mangled packet and the same amount of headroom as old sk_buff. While looking at how the regression appeared (e2b58a67), I noticed the same pattern in ipq_mangle_ipv6() and ipq_mangle_ipv4(). The patch corrects those locations too. Tested with bigger reinjected IPv6 packets (nfqnl_mangle() path), things are ok (2.6.25 and today's net-2.6 git tree).

2008-04-29[netdrvr] gianfar: Determine TBIPA value dynamicallyPaul Gortmaker
TBIPA needs to be set to a value (on connected MDIO buses) that doesn't conflict with PHYs on the bus. By hardcoding it to 0x1f, we were preventing boards with PHYs at 0x1f from working properly. Instead, scan the bus when it comes up, and find an address that doesn't have a PHY on it. The TBI PHY configuration code then trusts that the value in TBIPA is either safe, or doesn't matter (ie - it's not an active bus with other PHYs).

2008-04-27tcp: Fix slab corruption with ipv6 and tcp6fuzzEvgeniy Polyakov
From: Evgeniy Polyakov <johnpol@2ka.mipt.ru> This fixes a regression added by ec3c0982a2dd1e671bad8e9d26c28dcba0039d87 ("[TCP]: TCP_DEFER_ACCEPT updates - process as established") tcp_v6_do_rcv()->tcp_rcv_established(), the latter goes to step5, where eventually skb can be freed via tcp_data_queue() (drop: label), then if check for tcp_defer_accept_check() returns true and thus tcp_rcv_established() returns -1, which forces tcp_v6_do_rcv() to jump to reset: label, which in turn will pass through discard: label and free the same skb again. Tested by Eric Sesterhenn. Signed-off-by: David S. Miller <davem@davemloft.net> Acked-By: Patrick McManus <mcmanus@ducksong.com>
