2008-01-09fat: optimize fat_count_free_clusters()OGAWA Hirofumi1-0/+28
On large partition, scanning the free clusters is very slow if users doesn't use "usefree" option. For optimizing it, this patch uses sb_breadahead() to read of FAT sectors. On some user's 15GB partition, this patch improved it very much (1min => 600ms).

2008-01-06CPU hotplug: fix cpu_is_offline() on !CONFIG_HOTPLUG_CPUIngo Molnar2-4/+2
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.

2008-01-06Revert "scsi: revert "[SCSI] Get rid of scsi_cmnd->done""Linus Torvalds9-58/+43
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).

2008-01-04[ISDN]: i4l: Fix DLE handling for i4l-audioMatthias Goebl2-0/+5
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.

2008-01-04[ISDN] i4l: 'NO CARRIER' message lost after ldisc flushMatthias Goebl1-0/+5
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?

This reverts changeset fa4f0774d7c6cccb4d1fda76b91dd8eddcb2dd6a ([CASSINI]: dont touch page_count) because it breaks the driver. The local page counting added by this changeset did not account for the asynchronous page count changes done by kfree_skb() and friends. The change adds extra atomics and on top of it all appears to be totally unnecessary as well. Signed-off-by: David S. Miller <davem@davemloft.net> Acked-by: Nick Piggin <npiggin@suse.de>
2008-01-04[CASSINI]: Fix endianness bug.Al Viro2-12/+14
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>

2008-01-04[X25]: Add missing x25_neigh_putJulia Lawall1-2/+3
The function x25_get_neigh increments a reference count. At the point of the second goto out, the result of calling x25_get_neigh is only stored in a local variable, and thus no one outside the function will be able to decrease the reference count. Thus, x25_neigh_put should be called before the return in this case. The problem was found using the following semantic match. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T,T1,T2; identifier E; statement S; expression x1,x2,x3; int ret; @@ T E; ... * if ((E = x25_get_neigh(...)) == NULL) S ... when != x25_neigh_put(...,(T1)E,...) when != if (E != NULL) { ... x25_neigh_put(...,(T1)E,...); ...} when != x1 = (T1)E when != E = x3; when any if (...) { ... when != x25_neigh_put(...,(T2)E,...) when != if (E != NULL) { ... x25_neigh_put(...,(T2)E,...); ...} when != x2 = (T2)E ( * return; | * return ret; ) } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

The console is now by default in UTF-8 mode. Fix the documentation on the default value, so that we can explain behaviour that otherwise causes bug-reports like this: http://bugzilla.kernel.org/show_bug.cgi?id=9319 Also add the needed "vt." prefix, so that the boot-time config options to switch back to the legacy 8-bit mode is actually documented correctly.
