a263898 Ingo Molnar 30 December 2007, 10:58:17 UTC CPU hotplug: fix cpu_is_offline() on !CONFIG_HOTPLUG_CPU make randconfig bootup testing found that the cpufreq code crashes on bootup, if the powernow-k8 driver is enabled and if maxcpus=1 passed on the boot line to a !CONFIG_HOTPLUG_CPU kernel. First lockdep found out that there's an inconsistent unlock sequence: ===================================== [ BUG: bad unlock balance detected! ] ------------------------------------- swapper/1 is trying to release lock (&per_cpu(cpu_policy_rwsem, cpu)) at: [<ffffffff806ffd8e>] unlock_policy_rwsem_write+0x3c/0x42 but there are no more locks to release!

This opened up the possibility to add the non-initialized sysdev device of the secondary core: cpufreq-core: trying to register driver powernow-k8 cpufreq-core: adding CPU 0 powernow-k8: BIOS error - no PSB or ACPI _PSS objects cpufreq-core: initialization failed cpufreq-core: adding CPU 1 cpufreq-core: initialization failed which then blew up. The fix is to make cpu_is_offline() always the negation of cpu_online(). With that fix applied the kernel boots up fine without crashing: Calling initcall 0xffffffff80cc0510: powernowk8_init+0x0/0x94() powernow-k8: Found 1 AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ processors (1 cpu cores) (version 2.20.00) powernow-k8: BIOS error - no PSB or ACPI _PSS objects initcall 0xffffffff80cc0510: powernowk8_init+0x0/0x94() returned -19. initcall 0xffffffff80cc0510 ran for 19 msecs: powernowk8_init+0x0/0x94() Calling initcall 0xffffffff80cc328f: init_lapic_nmi_sysfs+0x0/0x39() We could fix this by making CPU enumeration aware of max_cpus, but that would be more fragile IMO, and the cpu_online(cpu) != cpu_is_offline(cpu) possibility was quite confusing and a continuous source of bugs too. Most distributions have kernels with CPU hotplug enabled, so this bug remained hidden for a long time. Bug forensics: The broken cpu_is_offline() API variant was introduced via: commit a59d2e4e6977e7b94e003c96a41f07e96cddc340 Author: Rusty Russell <rusty@rustcorp.com.au> Date: Mon Mar 8 06:06:03 2004 -0800 [PATCH] minor cleanups for hotplug CPUs ( this predates linux-2.6.git, this commit is available from Thomas's historic git tree. ) Then 1.5 years later the cpufreq code made use of it: commit c32b6b8e524d2c337767d312814484d9289550cf Author: Ashok Raj <ashok.raj@intel.com> Date: Sun Oct 30 14:59:54 2005 -0800 [PATCH] create and destroy cpufreq sysfs entries based on cpu notifiers + if (cpu_is_offline(cpu)) + return 0; which is a correct use of the subtly broken new API. v2.6.15 then shipped with this bug included. then it took two more years for random-kernel qa to hit it.

7b3d954 Linus Torvalds 06 January 2008, 18:17:12 UTC Revert "scsi: revert "[SCSI] Get rid of scsi_cmnd->done"" This reverts commit ac40532ef0b8649e6f7f83859ea0de1c4ed08a19, which gets us back the original cleanup of 6f5391c283d7fdcf24bf40786ea79061919d1e1d. It turns out that the bug that was triggered by that commit was apparently not actually triggered by that commit at all, and just the testing conditions had changed enough to make it appear to be due to it. The real problem seems to have been found by Peter Osterlund: "pktcdvd sets it [block device size] when opening the /dev/pktcdvd device, but when the drive is later opened as /dev/scd0, there is nothing that sets it back. (Btw, 40944 is possible if the disk is a CDRW that was formatted with "cdrwtool -m 10236".) The problem is that pktcdvd opens the cd device in non-blocking mode when pktsetup is run, and doesn't close it again until pktsetup -d is run. The effect is that if you meanwhile open the cd device, blkdev.c:do_open() doesn't call bd_set_size() because bdev->bd_openers is non-zero." In particular, to repeat the bug (regardless of whether commit 6f5391c283d7fdcf24bf40786ea79061919d1e1d is applied or not): " 1. Start with an empty drive. 2. pktsetup 0 /dev/scd0 3. Insert a CD containing an isofs filesystem. 4. mount /dev/pktcdvd/0 /mnt/tmp 5. umount /mnt/tmp 6. Press the eject button. 7. Insert a DVD containing a non-writable filesystem. 8. mount /dev/scd0 /mnt/tmp 9. find /mnt/tmp -type f -print0 | xargs -0 sha1sum >/dev/null 10. If the DVD contains data beyond the physical size of a CD, you get I/O errors in the terminal, and dmesg reports lots of "attempt to access beyond end of device" errors." which in turn is because the nested open after the media change won't cause the size to be set properly (because the original open still holds the block device, and we only do the bd_set_size() when we don't have other people holding the device open). The proper fix for that is probably to just do something like bdev->bd_inode->i_size = (loff_t)get_capacity(disk)<<9; in fs/block_dev.c:do_open() even for the cases where we're not the original opener (but *not* call bd_set_size(), since that will also change the block size of the device).

7fde4d7 Matthias Goebl 04 January 2008, 11:45:28 UTC [ISDN]: i4l: Fix DLE handling for i4l-audio The DLE handling in i4l-audio seems to be broken. It produces spurious DLEs so asterisk 1.2.24 with chan_modem_i4l gets irritated, the error message is: "chan_modem_i4l.c:450 i4l_read: Value of escape is ^ (17)". -> There shouldn't be a DLE-^. If a spurious DLE-ETX occurs, the audio connection even dies. I use a "AVM Fritz!PCI" isdn card. I found two issues that only appear if ISDN_AUDIO_SKB_DLECOUNT(skb) > 0: - The loop in isdn_tty.c:isdn_tty_try_read() doesn't escape a DLE if it's the last character. - The loop in isdn_common.c:isdn_readbchan_tty() doesn't copy its characters, it only remembers the last one ("last = *p;"). Compare it with the loop in isdn_common.c:isdn_readbchan(), that *does* copy them ("*cp++ = *p;") correctly. The special handling of the "last" character made it more difficult. I compared it to linux-2.4.19: There was no "last"-handling and both loops did escape and copy all characters correctly.

00409bb Matthias Goebl 04 January 2008, 10:19:30 UTC [ISDN] i4l: 'NO CARRIER' message lost after ldisc flush The ISDN tty layer doesn't produce a 'NO CARRIER' message after hangup. I suppose it broke when tty_buffer_flush() has been added to tty_ldisc_flush() in the commit below. For isdn_tty_modem_result(RESULT_NO_CARRIER..) the message inserted via isdn_tty_at_cout() -> tty_insert_flip_char() is flushed immediately by tty_ldisc_flush() -> tty_buffer_flush(). More annoyingly, the audio abort sequence DLE-ETX is also lost. This patch fixes only active audio connections, because I assume that nobody changes the line discipline for audio. For non-audio connections the problem remains. Maybe we can remove the tty_ldisc_flush() in isdn_tty_modem_result() at all because it's done at tty_close?

e5e0254 Al Viro 04 January 2008, 02:49:00 UTC [CASSINI]: Fix endianness bug. Here's proposed fix for RX checksum handling in cassini; it affects little-endian working with half-duplex gigabit, but obviously needs testing on big-endian too. The problem is, we need to convert checksum to fixed-endian *before* correcting for (unstripped) FCS. On big-endian it won't matter (conversion is no-op), on little-endian it will, but only if FCS is not stripped by hardware; i.e. in half-duplex gigabit mode when ->crc_size is set. cassini.c part is that fix, cassini.h one consists of trivial endianness annotations. With that applied the sucker is endian-clean, according to sparse. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net> 04 January 2008, 08:47:04 UTC

e6e2197 Trond Myklebust 02 January 2008, 21:27:16 UTC NFSv4: Fix open_to_lock_owner sequenceid allocation... NFSv4 file locking is currently completely broken since it doesn't respect the OPEN sequencing when it is given an unconfirmed lock_owner and needs to do an open_to_lock_owner. Worse: it breaks the sunrpc rules by doing a GFP_KERNEL allocation inside an rpciod callback. Fix is to preallocate the open seqid structure in nfs4_alloc_lockdata if we see that the lock_owner is unconfirmed. Then, in nfs4_lock_prepare() we wait for either the open_seqid, if the lock_owner is still unconfirmed, or else fall back to waiting on the standard lock_seqid.

751bf4d James Bottomley 02 January 2008, 17:14:30 UTC [SCSI] scsi_sysfs: restore prep_fn when ULD is removed A recent bug report: http://bugzilla.kernel.org/show_bug.cgi?id=9674 Was caused because the ULDs now set their own prep functions, but don't necessarily reset the prep function back to the SCSI default when they are removed. This leads to panics if commands are sent to the device after the module is removed because the prep_fn is still pointing to the old module code. The fix for this is to implement a bus remove method that resets the prep_fn pointer correctly before calling the ULD specific driver remove method.

2072c22 Gavin McCullagh 30 December 2007, 03:11:21 UTC [TCP]: use non-delayed ACK for congestion control RTT When a delayed ACK representing two packets arrives, there are two RTT samples available, one for each packet. The first (in order of seq number) will be artificially long due to the delay waiting for the second packet, the second will trigger the ACK and so will not itself be delayed. According to rfc1323, the SRTT used for RTO calculation should use the first rtt, so receivers echo the timestamp from the first packet in the delayed ack. For congestion control however, it seems measuring delayed ack delay is not desirable as it varies independently of congestion. The patch below causes seq_rtt and last_ackt to be updated with any available later packet rtts which should have less (and hopefully zero) delack delay. The rtt value then gets passed to ca_ops->pkts_acked(). Where TCP_CONG_RTT_STAMP was set, effort was made to supress RTTs from within a TSO chunk (!fully_acked), using only the final ACK (which includes any TSO delay) to generate RTTs. This patch removes these checks so RTTs are passed for each ACK to ca_ops->pkts_acked(). For non-delay based congestion control (cubic, h-tcp), rtt is sometimes used for rtt-scaling. In shortening the RTT, this may make them a little less aggressive. Delay-based schemes (eg vegas, veno, illinois) should get a cleaner, more accurate congestion signal, particularly for small cwnds. The congestion control module can potentially also filter out bad RTTs due to the delayed ack alarm by looking at the associated cnt which (where delayed acking is in use) should probably be 1 if the alarm went off or greater if the ACK was triggered by a packet.

We're exporting an __init function, oops :-) The core issue here is that add_preferred_console() is marked as __init, this makes it impossible to invoke this thing from a driver probe routine which is what the Sparc serial drivers need to do. There is no harm in dropping the __init marker. This code will actually work properly when invoked from a modular driver, except that init will probably not pick up the console change without some other support code. Then we can drop the __init from sunserial_console_match() and we're no longer exporting an __init function to modules. Signed-off-by: David S.

It turns out to be a fairly blatant oversight on my part whereby ic_enable is never set, and thus autoconfiguration is never enabled. Clearly my testing was broken :-( The solution that I have is to set ic_enable to 1 if we hit ip_auto_config_setup(), which basically means that autoconfiguration is activated unless told otherwise. I then flip ic_enable to 0 if ip=off, ip=none, ip=::::::off or ip=::::::none using ic_proto_name(); The incremental patch is below, let me know if a non-incremental version is prepared, as I did as for the original patch to be reverted pending a fix.

ad7edfe Linus Torvalds 28 December 2007, 05:21:36 UTC [PCI] Do not enable CRS Software Visibility by default It appears that some PCI-E bridges do the wrong thing in the presense of CRS Software Visibility and MMCONFIG. In particular, it looks like an ATI bridge (device ID 7936) will return 0001 in the vendor ID field of any bridged devices indefinitely. Not enabling CRS SV avoids the problem, and as we currently do not really make good use of the feature anyway (we just time out rather than do any threaded discovery as suggested by the CRS specs), we're better off just not enabling it. This should fix a slew of problem reports with random devices (generally graphics adapters or fairly high-performance networking cards, since it only affected PCI-E) not getting properly recognized on these AMD systems. If we really want to use CRS-SV, we may end up eventually needing a whitelist of systems where this should be enabled, along with some kind of "pcibios_enable_crs()" query to call the system-specific code.

fae718d Patrick McHardy 25 December 2007, 05:09:10 UTC [NETFILTER]: nf_conntrack_ipv4: fix module parameter compatibility Some users do "modprobe ip_conntrack hashsize=...". Since we have the module aliases this loads nf_conntrack_ipv4 and nf_conntrack, the hashsize parameter is unknown for nf_conntrack_ipv4 however and makes it fail. Allow to specify hashsize= for both nf_conntrack and nf_conntrack_ipv4. Note: the nf_conntrack message in the ringbuffer will display an incorrect hashsize since nf_conntrack is first pulled in as a dependency and calculates the size itself, then it gets changed through a call to nf_conntrack_set_hashsize().

db99247 Cory T. Tusar 23 December 2007, 20:34:51 UTC tty: fix logic change introduced by wait_event_interruptible_timeout() Commit 5a52bd4a2dcb570333ce6fe2e16cd311650dbdc8 introduced a subtle logic change in tty_wait_until_sent(). The original version would only error out of the 'do { ... } while (timeout)' loop if signal_pending() evaluated to true; a timeout or break due to an empty buffer would fall out of the loop and into the tty->driver->wait_until_sent handling. The current implementation will error out on either a pending signal or an empty buffer, falling through to the tty->driver->wait_until_sent handling only on a timeout. The ->wait_until_sent() will not be reached if the buffer empties before timeout jiffies have elapsed. This behavior differs from that prior to commit 5a52bd4a2dcb570333ce6fe2e16cd311650dbdc8. I turned this up while using a little serial download utility to bootstrap an ARM-based eval board. The util worked fine on 2.6.22.x, but consistently failed on 2.6.23.x. Once I'd determined that, I narrowed things down with git bisect, and found the above difference in logic in tty_wait_until_sent() by inspection. This change reverts the logic flow in tty_wait_until_sent() to match that prior to the aforementioned commit. Signed-off-by: Cory T.

f16b34a Peter Zijlstra 22 December 2007, 22:03:29 UTC lib: proportion: fix underflow in prop_norm_percpu() Zhe Jiang noticed that its possible to underflow pl->events in prop_norm_percpu() when the value returned by percpu_counter_read() is less than the error on that read and the period delay > 1. In that case half might not trigger the batch increment and the value will be identical on the next iteration, causing the same half to be subtracted again and again. Fix this by rewriting the division as a single subtraction instead of a subtraction loop and using percpu_counter_sum() when the value returned by percpu_counter_read() is smaller than the error. The latter is still needed if we want pl->events to shrink properly in the error region.
