2010-06-24tcp: do not send reset to already closed socketsKonstantin Khorenko
i've found that tcp_close() can be called for an already closed socket, but still sends reset in this case (tcp_send_active_reset()) which seems to be incorrect. Moreover, a packet with reset is sent with different source port as original port number has been already cleared on socket. Besides that incrementing stat counter for LINUX_MIB_TCPABORTONCLOSE also does not look correct in this case. Initially this issue was found on 2.6.18-x RHEL5 kernel, but the same seems to be true for the current mainstream kernel (checked on 2.6.35-rc3). Please, correct me if i missed something. How that happens: 1) the server receives a packet for socket in TCP_CLOSE_WAIT state that triggers a tcp_reset(): Call Trace: <IRQ> [<ffffffff8025b9b9>] tcp_reset+0x12f/0x1e8 [<ffffffff80046125>] tcp_rcv_state_process+0x1c0/0xa08 [<ffffffff8003eb22>] tcp_v4_do_rcv+0x310/0x37a [<ffffffff80028bea>] tcp_v4_rcv+0x74d/0xb43 [<ffffffff8024ef4c>] ip_local_deliver_finish+0x0/0x259 [<ffffffff80037131>] ip_local_deliver+0x200/0x2f4 [<ffffffff8003843c>] ip_rcv+0x64c/0x69f [<ffffffff80021d89>] netif_receive_skb+0x4c4/0x4fa [<ffffffff80032eca>] process_backlog+0x90/0xec [<ffffffff8000cc50>] net_rx_action+0xbb/0x1f1 [<ffffffff80012d3a>] __do_softirq+0xf5/0x1ce [<ffffffff8001147a>] handle_IRQ_event+0x56/0xb0 [<ffffffff8006334c>] call_softirq+0x1c/0x28 [<ffffffff80070476>] do_softirq+0x2c/0x85 [<ffffffff80070441>] do_IRQ+0x149/0x152 [<ffffffff80062665>] ret_from_intr+0x0/0xa <EOI> [<ffffffff80008a2e>] __handle_mm_fault+0x6cd/0x1303 [<ffffffff80008903>] __handle_mm_fault+0x5a2/0x1303 [<ffffffff80033a9d>] cache_free_debugcheck+0x21f/0x22e [<ffffffff8006a263>] do_page_fault+0x49a/0x7dc [<ffffffff80066487>] thread_return+0x89/0x174 [<ffffffff800c5aee>] audit_syscall_exit+0x341/0x35c [<ffffffff80062e39>] error_exit+0x0/0x84 tcp_rcv_state_process() ... // (sk_state == TCP_CLOSE_WAIT here) ... /* step 2: check RST bit */ if(th->rst) { tcp_reset(sk); goto discard; } ... --------------------------------- tcp_rcv_state_process tcp_reset tcp_done tcp_set_state(sk, TCP_CLOSE); inet_put_port __inet_put_port inet_sk(sk)->num = 0; sk->sk_shutdown = SHUTDOWN_MASK; 2) After that the process (socket owner) tries to write something to that socket and "inet_autobind" sets a _new_ (which differs from the original!) port number for the socket: Call Trace: [<ffffffff80255a12>] inet_bind_hash+0x33/0x5f [<ffffffff80257180>] inet_csk_get_port+0x216/0x268 [<ffffffff8026bcc9>] inet_autobind+0x22/0x8f [<ffffffff80049140>] inet_sendmsg+0x27/0x57 [<ffffffff8003a9d9>] do_sock_write+0xae/0xea [<ffffffff80226ac7>] sock_writev+0xdc/0xf6 [<ffffffff800680c7>] _spin_lock_irqsave+0x9/0xe [<ffffffff8001fb49>] __pollwait+0x0/0xdd [<ffffffff8008d533>] default_wake_function+0x0/0xe [<ffffffff800a4f10>] autoremove_wake_function+0x0/0x2e [<ffffffff800f0b49>] do_readv_writev+0x163/0x274 [<ffffffff80066538>] thread_return+0x13a/0x174 [<ffffffff800145d8>] tcp_poll+0x0/0x1c9 [<ffffffff800c56d3>] audit_syscall_entry+0x180/0x1b3 [<ffffffff800f0dd0>] sys_writev+0x49/0xe4 [<ffffffff800622dd>] tracesys+0xd5/0xe0 3) sendmsg fails at last with -EPIPE (=> 'write' returns -EPIPE in userspace): F: tcp_sendmsg1 -EPIPE: sk=ffff81000bda00d0, sport=49847, old_state=7, new_state=7, sk_err=0, sk_shutdown=3 Call Trace: [<ffffffff80027557>] tcp_sendmsg+0xcb/0xe87 [<ffffffff80033300>] release_sock+0x10/0xae [<ffffffff8016f20f>] vgacon_cursor+0x0/0x1a7 [<ffffffff8026bd32>] inet_autobind+0x8b/0x8f [<ffffffff8003a9d9>] do_sock_write+0xae/0xea [<ffffffff80226ac7>] sock_writev+0xdc/0xf6 [<ffffffff800680c7>] _spin_lock_irqsave+0x9/0xe [<ffffffff8001fb49>] __pollwait+0x0/0xdd [<ffffffff8008d533>] default_wake_function+0x0/0xe [<ffffffff800a4f10>] autoremove_wake_function+0x0/0x2e [<ffffffff800f0b49>] do_readv_writev+0x163/0x274 [<ffffffff80066538>] thread_return+0x13a/0x174 [<ffffffff800145d8>] tcp_poll+0x0/0x1c9 [<ffffffff800c56d3>] audit_syscall_entry+0x180/0x1b3 [<ffffffff800f0dd0>] sys_writev+0x49/0xe4 [<ffffffff800622dd>] tracesys+0xd5/0xe0 tcp_sendmsg() ... /* Wait for a connection to finish. */ if ((1 << sk->sk_state) & ~(TCPF_ESTABLISHED | TCPF_CLOSE_WAIT)) { int old_state = sk->sk_state; if ((err = sk_stream_wait_connect(sk, &timeo)) != 0) { if (f_d && (err == -EPIPE)) { printk("F: tcp_sendmsg1 -EPIPE: sk=%p, sport=%u, old_state=%d, new_state=%d, " "sk_err=%d, sk_shutdown=%d\n", sk, ntohs(inet_sk(sk)->sport), old_state, sk->sk_state, sk->sk_err, sk->sk_shutdown); dump_stack(); } goto out_err; } } ... 4) Then the process (socket owner) understands that it's time to close that socket and does that (and thus triggers sending reset packet): Call Trace: ...

sky2_phy_reinit is called by the ethtool helpers sky2_set_settings, sky2_nway_reset and sky2_set_pauseparam when netif_running. However, at the end of sky2_phy_init GM_GP_CTRL has GM_GPCR_RX_ENA and GM_GPCR_TX_ENA cleared. So, doing these commands causes the device to stop working: $ ethtool -r eth0 $ ethtool -A eth0 autoneg off Fix this issue by enabling Rx/Tx after running sky2_phy_init in sky2_phy_reinit.

2010-06-23net: consolidate netif_needs_gso() checksJohn Fastabend
netif_needs_gso() is checked twice in the TX path once, before submitting the skb to the qdisc and once after it is dequeued from the qdisc just before calling ndo_hard_start(). This opens a window for a user to change the gso/tso or tx checksum settings that can cause netif_needs_gso to be true in one check and false in the other. Specifically, changing TX checksum setting may cause the warning in skb_gso_segment() to be triggered if the checksum is calculated earlier. This consolidates the netif_needs_gso() calls so that the stack only checks if gso is needed in dev_hard_start_xmit().

2010-06-22hso: remove setting of low_latency flagFilip Aben
This patch removes the setting of the low_latency flag. tty_flip_buffer_push() is occasionally being called in irq context, which causes a hang if the low_latency flag is set. Removing the low_latency flag only seems to impact the flush to ldisc, which will now be put on a workqueue. Signed-off-by: Filip Aben <f.aben@option.com> Signed-off-by: David S.

2010-06-21udp: Fix bogus UFO packet generationHerbert Xu
It has been reported that the new UFO software fallback path fails under certain conditions with NFS. I tracked the problem down to the generation of UFO packets that are smaller than the MTU. The software fallback path simply discards these packets. This patch fixes the problem by not generating such packets on the UFO path.

2010-06-20caif: Add debug connection type for CAIF.Sjur Braendeland
Added new CAIF protocol type CAIFPROTO_DEBUG for accessing CAIF debug on the ST Ericsson modems. There are two debug servers on the modem, one for radio related debug (CAIF_RADIO_DEBUG_SERVICE) and the other for communication/application related debug (CAIF_COM_DEBUG_SERVICE). The debug connection can contain trace debug printouts or interactive debug used for debugging and test. Debug connections can be of type STREAM or SEQPACKET.
