2010-06-26net: optimize Berkeley Packet Filter (BPF) processingHagen Paul Pfeifer2-51/+209
Gcc is currenlty not in the ability to optimize the switch statement in sk_run_filter() because of dense case labels. This patch replace the OR'd labels with ordered sequenced case labels. The sk_chk_filter() function is modified to patch/replace the original OPCODES in a ordered but equivalent form. gcc is now in the ability to transform the switch statement in sk_run_filter into a jump table of complexity O(1). Until this patch gcc generates a sequence of conditional branches (O(n) of 567 byte .text segment size (arch x86_64): 7ff: 8b 06 mov (%rsi),%eax 801: 66 83 f8 35 cmp $0x35,%ax 805: 0f 84 d0 02 00 00 je adb <sk_run_filter+0x31d> 80b: 0f 87 07 01 00 00 ja 918 <sk_run_filter+0x15a> 811: 66 83 f8 15 cmp $0x15,%ax 815: 0f 84 c5 02 00 00 je ae0 <sk_run_filter+0x322> 81b: 77 73 ja 890 <sk_run_filter+0xd2> 81d: 66 83 f8 04 cmp $0x4,%ax 821: 0f 84 17 02 00 00 je a3e <sk_run_filter+0x280> 827: 77 29 ja 852 <sk_run_filter+0x94> 829: 66 83 f8 01 cmp $0x1,%ax [...] With the modification the compiler translate the switch statement into the following jump table fragment: 7ff: 66 83 3e 2c cmpw $0x2c,(%rsi) 803: 0f 87 1f 02 00 00 ja a28 <sk_run_filter+0x26a> 809: 0f b7 06 movzwl (%rsi),%eax 80c: ff 24 c5 00 00 00 00 jmpq *0x0(,%rax,8) 813: 44 89 e3 mov %r12d,%ebx 816: e9 43 03 00 00 jmpq b5e <sk_run_filter+0x3a0> 81b: 41 89 dc mov %ebx,%r12d 81e: e9 3b 03 00 00 jmpq b5e <sk_run_filter+0x3a0> Furthermore, I reordered the instructions to reduce cache line misses by order the most common instruction to the start.

2010-06-26enic: Use a lighter reset operation for enic devicesVasanthy Kolluri4-8/+55
The port profile information for a dynamic enic device is set by the upper layers, that are oblivious to the device reset operation. We do not want a reset operation erase the network state of a dynamic enic device as there is no way to set up the port profile information again. Hence a lighter reset operation called hang reset is used. Hang reset, unlike soft reset does not reset the network state and resets the host side state only.

2010-06-25tcp: do not send reset to already closed socketsKonstantin Khorenko1-0/+4
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.

This patch also fixes a problem in case the skb->data part of a fragmented skb spreads multiple pages. Signed-off-by: Frank Blaschka <frank.blaschka@de.ibm.com> Signed-off-by: David S.

2010-06-24qeth: fix use after free for qeths debug areaCarsten Otte1-1/+0
The function qeth_free_buffer_pool is called _after_ the per-card debug area has been released. This debug message is not all that usefull anyway, and thus gets removed.

2010-06-24qeth: Fold qeth_qerr debug areaCarsten Otte2-11/+4
This patch removes the qerr debug area. Most info that goes in here is logged to the card's local debug area already, those duplicates are removed. All other elements are moved to the card's local debug area. Signed-off-by: Carsten Otte <cotte@de.ibm.com> Signed-off-by: Frank Blaschka <frank.blaschka@de.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-06-24qeth: Fold qeth_misc debug areaCarsten Otte2-4/+1
This patch removes the misc debug area. Instead of logging the entire skb we just log a pointer to it into the card's local debug area in qeth_core_get_next_skb. Other then that, this debug area is not used anywhere. Signed-off-by: Carsten Otte <cotte@de.ibm.com> Signed-off-by: Frank Blaschka <frank.blaschka@de.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-06-24qeth: Fold qeth_sense debug areaCarsten Otte2-3/+0
This patch removes the sense debug area completely. Despite the name this debug area makes no sense at all because it's unused completely. Ouch.

2010-06-24qeth: Fold qeth_trace debug areaCarsten Otte4-272/+259
This patch removes the qeth_trace debug area. All relevant data is logged into either qeth_setup or into each card's own debug area. Superfluous information (such as the card number when logging into the card's own debug area) is removed without replacement.

2010-06-24qeth: Add new s390 debug feature for each qeth cardCarsten Otte2-3/+31
This patch adds a debug area for each qeth card. This debug area will replace various other debug areas that are global for all cards handled by the device driver. On crash dump analysis this makes life easier when trying to find out what's going on with an interface. Also, the forest of debug areas for this device driver is significantly cleared up.

2010-06-24qeth: Rework qeth_dbf_longtextCarsten Otte2-5/+5
This patch decouples qeth_dbf_longtext from qeth's static debug array. The function only uses one member anyway. Signed-off-by: Carsten Otte <cotte@de.ibm.com> Signed-off-by: Frank Blaschka <frank.blaschka@de.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-06-24smsgiucv: guarantee single iucv connect in thawUrsula Braun1-2/+9
If another smsgiucv_app device exists, suspend / resume fails with iucv path list corruption, because the same iucv_path_connect is called twice. The patch introduces a flag to save connect status of the smsgiucv path to make sure iucv_path_connect in smsg_pm_restore_thaw is called only once.
