TCP may advertize up to 16-bits window in SYN packets (no window scaling allowed). At the same time, TCP may have rcv_wnd (32-bits) that does not fit to 16-bits without window scaling resulting in pseudo garbage into advertized window from the low-order bits of rcv_wnd. This can happen at least when mss <= (1<<wscale) (see tcp_select_initial_window). This patch fixes the handling of SYN advertized windows (compile tested only). In worst case (which is unlikely to occur though), the receiver advertized window could be just couple of bytes. I'm not sure that such situation would be handled very well at all by the receiver!? Fortunately, the situation normalizes after the first non-SYN ACK is received because it has the correct, scaled window. Alternatively, tcp_select_initial_window could be changed to prevent too large rcv_wnd in the first place. [ tcp_make_synack() has the same bug, and I've added a fix for that to this patch -DaveM ] Signed-off-by:

The TCP reset packet is copied from the original. This includes all the GSO bits which do not apply to the new packet. So we should clear those bits. Spotted by Patrick McHardy. Signed-off-by:

This fixes the following problem: http://bugzilla.kernel.org/show_bug.cgi?id=7969 The MSI state needs to be saved during suspend. PCI state saved during tg3_init_one() does not contain valid MSI state because MSI hasn't been enabled. Signed-off-by:

Tetsuo Handa <handat@pm.nttdata.co.jp> told me that connect(2) with TCPv6 socket almost always took a few minutes to return when we did not have any ports available in the range of net.ipv4.ip_local_port_range. The reason was that we used incorrect seed for calculating index of hash when we check established sockets in __inet6_check_established(). Signed-off-by:

This reverts some bogosity from the dynamic command-line changes made on sparc32 and sparc64. Drivers such as drivers/sbus/char/openprom.c reference saved_command_line, and can be modular. The boot_command_line is __initdata, yet the dynamic command-line changes add modular exports of that symbol, obviously wrong. Signed-off-by: -

Since we look in both source and object directories for localversion* files, we accidentally ended up getting them twice. Use 'sort -u' to avoid that. Reported-by:

Regarding RFC3775, MH payload proto field should be IPPROTO_NONE. Otherwise it must be discarded (and the receiver should send ICMP error). We assume filter should drop such piggyback everytime to disallow slipping through firewall rules, even the final receiver will discard it. Signed-off-by:

NF_CT_STAT_INC assumes rcu_read_lock in nf_hook_slow disables preemption as well, making it legal to use __get_cpu_var without disabling preemption manually. The assumption is not correct anymore with preemptable RCU, additionally we need to protect against softirqs when not holding nf_conntrack_lock. Add NF_CT_STAT_INC_ATOMIC macro, which disables local softirqs, and use where necessary. Signed-off-by:
