* kbuild: fix bzImage build for x86Michael Tokarev2009-12-121-1/+1
| | | | | | | | | | | | | As has been discussed previously (and Sam has been CC'ed), the fix is still incorrect. It replaces "echo -ne" with "/bin/echo -ne", but neither of the two are guaranteed to support the necessary arguments and necessary (hexadecimal) escape sequences. What should be used here is printf(1). The trivial patch below (on top of these kbuild changes) fixes this issue.

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>

This patch is a trade off between not accepitng bogus EEPROMs and avoiding bogus bug reports allowing developers to focus instead on real concrete issues. If stable keeps bogus bug reports because of a possibly busted EEPROM feel free to apply this there too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | About 50% of shutdowns of b44 Ethernet adapter ends by kernel panic with kernels compiled with stack-protector. Checking b44_magic_pattern() return values, one call of b44_magic_pattern() returns 127. It means, that set_bit(128, pmask) was called on line 1509. It means that bit 0 of 17th byte of pmask was overwritten. But pmask has only 16 bytes. Stack corruption happens. It seems that set_bit() on line 1509 always writes one bit off. The fix does not only solve the stack corruption, but also makes Wake On LAN working on my onboard B44 on Asus A7V-333X mainboard. It seems that this problem affects all kernel versions since commit 725ad800 ([PATCH] b44: add wol for old nic) on 2006-06-20.

| * | tcp: fix retrans_stamp advancing in error casesIlpo Järvinen2009-12-081-3/+32

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).

Currently, timeout decisions are made on the basis of the current tcp_time_stamp and retrans_stamp, which is usually set at the first retransmission. However, if the retransmission fails in tcp_retransmit_skb(), retrans_stamp is not updated and remains zero. This leads to wrong decisions in retransmits_timed_out() if tcp_time_stamp is larger than the specified timeout, which is very likely. In this case, the TCP connection dies after the first attempted (and unsuccessful) retransmission. With this patch, tcp_skb_cb->when is used instead, when retrans_stamp is not available. This bug has been introduced together with retransmits_timed_out() in 2.6.32, as the number of retransmissions has been used for timeout decisions before. The corresponding commit was 6fa12c85031485dff38ce550c24f10da23b0adaa (Revert Backoff [v3]: Calculate TCP's connection close threshold as a time value.).

| * | net/mpc5200: Fix locking on fec_mpc52xx driverAsier Llano2009-12-081-59/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the locking scheme on the fec_mpc52xx driver. This device can receive IRQs from three sources; the FEC itself, the tx DMA, and the rx DMA. Mutual exclusion was handled by taking a spin_lock() in the critical regions, but because the handlers are run with IRQs enabled, spin_lock() is insufficient and the driver can end up interrupting a critical region anyway from another IRQ. Asier Llano discovered that this occurs when an error IRQ is raised in the middle of handling rx irqs which resulted in an sk_buff memory leak. In addition, locking is spotty at best in the driver and inspection revealed quite a few places with insufficient locking. This patch is based on Asier's initial work, but reworks a number of things so that locks are held for as short a time as possible, so that spin_lock_irqsave() is used everywhere, and so the locks are dropped when calling into the network stack (because the lock only protects the hardware interface; not the network stack). Boot tested on a lite5200 with an NFS root. Has not been performance tested.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we find a timewait connection in __inet_hash_connect() and reuse it for a new connection request, we have a race window, releasing bind list lock and reacquiring it in __inet_twsk_kill() to remove timewait socket from list. 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. Note: This problem happens if sysctl_tcp_tw_reuse is set. Reported-by: kapil dakhane <kdakhane@gmail.com> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
