2009-12-15tree-wide: convert open calls to remove spaces to skip_spaces() lib functionAndré Goddard Rosa
Makes use of skip_spaces() defined in lib/string.c for removing leading spaces from strings all over the tree. It decreases lib.a code size by 47 bytes and reuses the function tree-wide: text data bss dec hex filename 64688 584 592 65864 10148 (TOTALS-BEFORE) 64641 584 592 65817 10119 (TOTALS-AFTER) Also, while at it, if we see (*str && isspace(*str)), we can be sure to remove the first condition (*str) as the second one (isspace(*str)) also evaluates to 0 whenever *str == 0, making it redundant. In other words, "a char equals zero is never a space". Julia Lawall tried the semantic patch (http://coccinelle.lip6.fr) below, and found occurrences of this pattern on 3 more files: drivers/leds/led-class.c drivers/leds/ledtrig-timer.c drivers/video/output.c @@ expression str; @@ ( // ignore skip_spaces cases while (*str && isspace(*str)) { \(str++;\|++str;\) } | - *str && isspace(*str) ) Signed-off-by: André Goddard Rosa <andre.goddard@gmail.com> Cc: Julia Lawall <julia@diku.dk> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: Jeff Dike <jdike@addtoit.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: "H.

2009-12-11net: Handle NETREG_UNINITIALIZED devices correctlyKrishna Kumar
Fix two problems: 1. If unregister_netdevice_many() is called with both registered and unregistered devices, rollback_registered_many() bails out when it reaches the first unregistered device. The processing of the prior registered devices is unfinished, and the remaining devices are skipped, and possible registered netdev's are leaked/unregistered. 2. System hangs or panics depending on how the devices are passed, since when netdev_run_todo() runs, some devices were not fully processed. Tested by passing intermingled unregistered and registered vlan devices to unregister_netdevice_many() as follows: 1. dev, fake_dev1, fake_dev2: hangs in run_todo ("unregister_netdevice: waiting for eth1.100 to become free. Usage count = 1") 2. fake_dev1, dev, fake_dev2: failure during de-registration and next registration, followed by a vlan driver Oops during subsequent registration. Confirmed that the patch fixes both cases. Signed-off-by: Krishna Kumar <krkumar2@in.ibm.com> Acked-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-12-08tcp: fix retrans_stamp advancing in error casesIlpo Järvinen
It can happen, that tcp_retransmit_skb fails due to some error. In such cases we might end up into a state where tp->retrans_out is zero but that's only because we removed the TCPCB_SACKED_RETRANS bit from a segment but couldn't retransmit it because of the error that happened. Therefore some assumptions that retrans_out checks are based do not necessarily hold, as there still can be an old retransmission but that is only visible in TCPCB_EVER_RETRANS bit. As retransmission happen in sequential order (except for some very rare corner cases), it's enough to check the head skb for that bit. Main reason for all this complexity is the fact that connection dying time now depends on the validity of the retrans_stamp, in particular, that successive retransmissions of a segment must not advance retrans_stamp under any conditions. It seems after quick thinking that this has relatively low impact as eventually TCP will go into CA_Loss and either use the existing check for !retrans_stamp case or send a retransmission successfully, setting a new base time for the dying timer (can happen only once). At worst, the dying time will be approximately the double of the intented time. In addition, tcp_packet_delayed() will return wrong result (has some cc aspects but due to rarity of these errors, it's hardly an issue). One of retrans_stamp clearing happens indirectly through first going into CA_Open state and then a later ACK lets the clearing to happen. Thus tcp_try_keep_open has to be modified too. Thanks to Damian Lukowski <damian@tvk.rwth-aachen.de> for hinting that this possibility exists (though the particular case discussed didn't after all have it happening but was just a debug patch artifact).

2009-12-08tcp: Fix a connect() race with timewait socketsEric Dumazet

Another thread might find the timewait socket we already chose, leading to list corruption and crashes. Fix is to remove timewait socket from bind list before releasing the bind lock.

On a 32-bit machine, BIT() macro does not give the required bit value if the bit is mroe than 31. In ieee802_11_parse_elems_crc(), BIT() is suppossed to get the bit value more than 31 (42 (id of ERP_INFO_IE), 37 (CHANNEL_SWITCH_IE), (42), 32 (POWER_CONSTRAINT_IE), 45 (HT_CAP_IE), 61 (HT_INFO_IE)).

2009-12-04mac80211: Fix TX status reporting for injected data framesJouni Malinen
An earlier optimization on removing unnecessary traffic on cooked monitor interfaces ("mac80211: reduce the amount of unnecessary traffic on cooked monitor interfaces ") ended up removing quite a bit more than just unnecessary traffic. It was not supposed to remove TX status reporting for injected frames, but ended up doing it by checking the injected flag in skb->cb only after that field had been cleared with memset.. Fix this by taking a local copy of the injected flag before skb->cb is cleared. This broke user space applications that depend on getting TX status notifications for injected data frames. For example, STA inactivity poll from hostapd did not work and ended up kicking out stations even if they were still present. Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W.

After TCP RCU conversion, tw->tw_refcnt should not be set to 1 in inet_twsk_alloc(). It allows a RCU reader to get this timewait socket, while we not yet stabilized it. Only choice we have is to set tw_refcnt to 0 in inet_twsk_alloc(), then atomic_add() it later, once everything is done. Location of this atomic_add() is tricky, because we dont want another writer to find this timewait in ehash, while tw_refcnt is still zero ! Thanks to Kapil Dakhane tests and reports.

2009-12-03tcp: connect() race with timewait reuseEric Dumazet
Its currently possible that several threads issuing a connect() find the same timewait socket and try to reuse it, leading to list corruptions. Condition for bug is that these threads bound their socket on same address/port of to-be-find timewait socket, and connected to same target. (SO_REUSEADDR needed) To fix this problem, we could unhash timewait socket while holding ehash lock, to make sure lookups/changes will be serialized. Only first thread finds the timewait socket, other ones find the established socket and return an EADDRNOTAVAIL error. This second version takes into account Evgeniy's review and makes sure inet_twsk_put() is called outside of locked sections.

2009-12-03tcp: diag: Dont report negative values for rx queueEric Dumazet
Both netlink and /proc/net/tcp interfaces can report transient negative values for rx queue. ss -> State Recv-Q Send-Q Local Address:Port Peer Address:Port ESTAB -6 6 127.0.0.1:45956 127.0.0.1:3333 netstat -> tcp 4294967290 6 127.0.0.1:37784 127.0.0.1:3333 ESTABLISHED This is because we dont lock socket while computing tp->rcv_nxt - tp->copied_seq, and another CPU can update copied_seq before rcv_next in RX path.
