24b9568 James Chapman 04 June 2008, 22:54:07 UTC l2tp: Fix possible oops if transmitting or receiving when tunnel goes down Some problems have been experienced in the field which cause an oops in the pppol2tp driver if L2TP tunnels fail while passing data. The pppol2tp driver uses private data that is referenced via the sk->sk_user_data of its UDP and PPPoL2TP sockets. This patch makes sure that the driver uses sock_hold() when it holds a reference to the sk pointer. This affects its sendmsg(), recvmsg(), getname(), [gs]etsockopt() and ioctl() handlers. Tested by ISP where problem was seen. System has been up 10 days with no oops since running this patch. Without the patch, an oops would occur every 1-2 days.

293ad60 Octavian Purdila 04 June 2008, 22:45:58 UTC tcp: Fix for race due to temporary drop of the socket lock in skb_splice_bits. skb_splice_bits temporary drops the socket lock while iterating over the socket queue in order to break a reverse locking condition which happens with sendfile. This, however, opens a window of opportunity for tcp_collapse() to aggregate skbs and thus potentially free the current skb used in skb_splice_bits and tcp_read_sock. This patch fixes the problem by (re-)getting the same "logical skb" after the lock has been temporary dropped. Based on idea and initial patch from Evgeniy Polyakov.

199f7d2 James Chapman 04 June 2008, 22:07:32 UTC lt2p: Fix possible WARN_ON from socket code when UDP socket is closed If an L2TP daemon closes a tunnel socket while packets are queued in the tunnel's reorder queue, a kernel warning is logged because the socket is closed while skbs are still referencing it. The fix is to purge the queue in the socket's release handler.

a660447 Ilpo Järvinen 04 June 2008, 19:07:44 UTC tcp: fix skb vs fack_count out-of-sync condition This bug is able to corrupt fackets_out in very rare cases. In order for this to cause corruption: 1) DSACK in the middle of previous SACK block must be generated. 2) In order to take that particular branch, part or all of the DSACKed segment must already be SACKed so that we have that in cache in the first place. 3) The new info must be top enough so that fackets_out will be updated on this iteration. ...then fack_count is updated while skb wasn't, then we walk again that particular segment thus updating fack_count twice for a single skb and finally that value is assigned to fackets_out by tcp_sacktag_one. It is safe to call tcp_sacktag_one just once for a segment (at DSACK), no need to call again for plain SACK. Potential problem of the miscount are limited to premature entry to recovery and to inflated reordering metric (which could even cancel each other out in the most the luckiest scenarios :-)). Both are quite insignificant in worst case too and there exists also code to reset them (fackets_out once sacked_out becomes zero and reordering metric on RTO). This has been reported by a number of people, because it occurred quite rarely, it has been very evasive. Andy Furniss was able to get it to occur couple of times so that a bit more info was collected about the problem using a debug patch, though it still required lot of checking around. Thanks also to others who have tried to help here. This is listed as Bugzilla #10346. The bug was introduced by me in commit 68f8353b48 ([TCP]: Rewrite SACK block processing & sack_recv_cache use), I probably thought back then that there's need to scan that entry twice or didn't dare to make it go through it just once there. Going through twice would have required restoring fack_count after the walk but as noted above, I chose to drop the additional walk step altogether here.

8aca6cb Ilpo Järvinen 04 June 2008, 18:34:22 UTC tcp: Fix inconsistency source (CA_Open only when !tcp_left_out(tp)) It is possible that this skip path causes TCP to end up into an invalid state where ca_state was left to CA_Open while some segments already came into sacked_out. If next valid ACK doesn't contain new SACK information TCP fails to enter into tcp_fastretrans_alert(). Thus at least high_seq is set incorrectly to a too high seqno because some new data segments could be sent in between (and also, limited transmit is not being correctly invoked there). Reordering in both directions can easily cause this situation to occur. I guess we would want to use tcp_moderate_cwnd(tp) there as well as it may be possible to use this to trigger oversized burst to network by sending an old ACK with huge amount of SACK info, but I'm a bit unsure about its effects (mainly to FlightSize), so to be on the safe side I just currently fixed it minimally to keep TCP's state consistent (obviously, such nasty ACKs have been possible this far). Though it seems that FlightSize is already underestimated by some amount, so probably on the long term we might want to trigger recovery there too, if appropriate, to make FlightSize calculation to resemble reality at the time when the losses where discovered (but such change scares me too much now and requires some more thinking anyway how to do that as it likely involves some code shuffling). This bug was found by Brian Vowell while running my TCP debug patch to find cause of another TCP issue (fackets_out miscount).

870568b Suresh Siddha 02 June 2008, 22:57:27 UTC x86, fpu: fix CONFIG_PREEMPT=y corruption of application's FPU stack Jürgen Mell reported an FPU state corruption bug under CONFIG_PREEMPT, and bisected it to commit v2.6.19-1363-gacc2076, "i386: add sleazy FPU optimization". Add tsk_used_math() checks to prevent calling math_state_restore() which can sleep in the case of !tsk_used_math(). This prevents making a blocking call in __switch_to(). Apparently "fpu_counter > 5" check is not enough, as in some signal handling and fork/exec scenarios, fpu_counter > 5 and !tsk_used_math() is possible. It's a side effect though. This is the failing scenario: process 'A' in save_i387_ia32() just after clear_used_math() Got an interrupt and pre-empted out. At the next context switch to process 'A' again, kernel tries to restore the math state proactively and sees a fpu_counter > 0 and !tsk_used_math() This results in init_fpu() during the __switch_to()'s math_state_restore() And resulting in fpu corruption which will be saved/restored (save_i387_fxsave and restore_i387_fxsave) during the remaining part of the signal handling after the context switch.

282c454 Venki Pallipadi 29 May 2008, 19:01:44 UTC x86: fix Xorg crash with xf86MapVidMem error Clarify the usage of mtrr_lookup() in PAT code, and to make PAT code resilient to mtrr lookup problems. Specifically, pat_x_mtrr_type() is restructured to highlight, under what conditions we look for mtrr hint. pat_x_mtrr_type() uses a default type when there are any errors in mtrr lookup (still maintaining the pat consistency). And, reserve_memtype() highlights its usage ot mtrr_lookup for request type of '-1' and also defaults in a sane way on any mtrr lookup failure. pat.c looks at mtrr type of a range to get a hint on what mapping type to request when user/API: (1) hasn't specified any type (/dev/mem mapping) and we do not want to take performance hit by always mapping UC_MINUS. This will be the case for /dev/mem mappings used to map BIOS area or ACPI region which are WB'able. In this case, as long as MTRR is not WB, PAT will request UC_MINUS for such mappings. (2) user/API requests WB mapping while in reality MTRR may have UC or WC. In this case, PAT can map as WB (without checking MTRR) and still effective type will be UC or WC. But, a subsequent request to map same region as UC or WC may fail, as the region will get trackked as WB in PAT list. Looking at MTRR hint helps us to track based on effective type rather than what user requested. Again, here mtrr_lookup is only used as hint and we fallback to WB mapping (as requested by user) as default. In both cases, after using the mtrr hint, we still go through the memtype list to make sure there are no inconsistencies among multiple users.

5c1ea08 Steven Rostedt 25 May 2008, 15:13:32 UTC x86: enable preemption in delay The RT team has been searching for a nasty latency. This latency shows up out of the blue and has been seen to be as big as 5ms! Using ftrace I found the cause of the latency. pcscd-2995 3dNh1 52360300us : irq_exit (smp_apic_timer_interrupt) pcscd-2995 3dN.2 52360301us : idle_cpu (irq_exit) pcscd-2995 3dN.2 52360301us : rcu_irq_exit (irq_exit) pcscd-2995 3dN.1 52360771us : smp_apic_timer_interrupt (apic_timer_interrupt ) pcscd-2995 3dN.1 52360771us : exit_idle (smp_apic_timer_interrupt) Here's an example of a 400 us latency. pcscd took a timer interrupt and returned with "need resched" enabled, but did not reschedule until after the next interrupt came in at 52360771us 400us later! At first I thought we somehow missed a preemption check in entry.S. But I also noticed that this always seemed to happen during a __delay call. pcscd-2995 3dN.2 52360836us : rcu_irq_exit (irq_exit) pcscd-2995 3.N.. 52361265us : preempt_schedule (__delay) Looking at the x86 delay, I found my problem. In git commit 35d5d08a085c56f153458c3f5d8ce24123617faf, Andrew Morton placed preempt_disable around the entire delay due to TSC's not working nicely on SMP. Unfortunately for those that care about latencies this is devastating! Especially when we have callers to mdelay(8). Here I enable preemption during the loop and account for anytime the task migrates to a new CPU. The delay asked for may be extended a bit by the migration, but delay only guarantees that it will delay for that minimum time. Delaying longer should not be an issue.

I actually suspect the logic was wrong before the changes but -rc isn't the time to play with that ata_sff_sync - ensure writes hit the device Really we want an io* operation for 'is posted' eg ioisposted(ioaddr) so that we can fix the nasty delay this causes on most systems. - ata_sff_pause - 400nS delay Ensure the command hit the device and delay 400nS - ata_sff_dma_pause Ensure the I/O hit the device and enforce an HDMA1:0 transition delay. Requires altstatus register exists, BUG if not so we don't risk corruption in MWDMA modes. (UDMA the checksum will save your backside in theory) The only other complication then is devices with their own handlers. rb532 can use dma_pause but scc needs to access its own altstatus register for internal errata workarounds so directly call the drivers own altstatus function.

664d080 Holger Macht 03 June 2008, 18:27:59 UTC [libata] ACPI: Properly handle bay devices in dock stations * Differentiate between bay devices in dock stations and others: - When an ACPI_NOTIFY_EJECT_REQUEST appears, just signal uevent to userspace (that is when the optional eject button on a bay device is pressed/pulled) giving the possibility to unmount file systems and to clean up. Also, only send uevent in case we get an EJECT_REQUEST without doing anything else. In other cases, you'll get an add/remove event because libata attaches/detaches the device. - In case of a dock event, which in turn signals an ACPI_NOTIFY_EJECT_REQUEST, immediately detach the device, because it may already have been gone * In case of an ACPI_NOTIFY_DEVICE/BUS_CHECK, evaluate _STA to check if the device has been plugged or unplugged. If plugged, hotplug it, if unplugged, just signal event to userspace (initial patch by Matthew Garrett <mjg59@srcf.ucam.org>) * Call ACPI _EJ0 for detached devices Signed-off-by: Holger Macht <hmacht@suse.de> Signed-off-by: Jeff Garzik <jgarzik@redhat.com> 04 June 2008, 10:28:50 UTC

b9f5f52 Stephen Hemminger 03 June 2008, 23:03:15 UTC net: neighbour table ABI problem The neighbor table time of last use information is returned in the incorrect unit. Kernel to user space ABI's need to use USER_HZ (or milliseconds), otherwise the application has to try and discover the real system HZ value which is problematic. Linux has standardized on keeping USER_HZ consistent (100hz) even when kernel is running internally at some other value. This change is small, but it breaks the ABI for older version of iproute2 utilities. But these utilities are already broken since they are looking at the psched_hz values which are completely different. So let's just go ahead and fix both kernel and user space. Older utilities will just print wrong values. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net> 03 June 2008, 23:03:15 UTC

537d59a Dave Young 02 June 2008, 06:50:52 UTC bluetooth: rfcomm_dev_state_change deadlock fix There's logic in __rfcomm_dlc_close: rfcomm_dlc_lock(d); d->state = BT_CLOSED; d->state_changed(d, err); rfcomm_dlc_unlock(d); In rfcomm_dev_state_change, it's possible that rfcomm_dev_put try to take the dlc lock, then we will deadlock. Here fixed it by unlock dlc before rfcomm_dev_get in rfcomm_dev_state_change. why not unlock just before rfcomm_dev_put? it's because there's another problem. rfcomm_dev_get/rfcomm_dev_del will take rfcomm_dev_lock, but in rfcomm_dev_add the lock order is : rfcomm_dev_lock --> dlc lock so I unlock dlc before the taken of rfcomm_dev_lock. Actually it's a regression caused by commit 1905f6c736cb618e07eca0c96e60e3c024023428 ("bluetooth : __rfcomm_dlc_close lock fix"), the dlc state_change could be two callbacks : rfcomm_sk_state_change and rfcomm_dev_state_change. I missed the rfcomm_sk_state_change that time. Thanks Arjan van de Ven <arjan@linux.intel.com> for the effort in commit 4c8411f8c115def968820a4df6658ccfd55d7f1a ("bluetooth: fix locking bug in the rfcomm socket cleanup handling") but he missed the rfcomm_dev_state_change lock issue.

64e9159 Alan Cox 03 June 2008, 14:18:54 UTC serial_core: uart_set_ldisc infrastructure The tty layer provides a callback that is used when the line discipline is changed. Some hardware uses this to configure hardware specific features such as IrDA mode on serial ports. Unfortunately the serial layer does not provide this feature or pass it down to drivers. Blackfin used to hack around this by rewriting the tty ops, but those are now properly shared and const so the hack fails. Instead provide the proper operations. This change plus a follow up from the Blackfin guys is needed to avoid blackfin losing features in this release.
