Doing a simple modprobe/rmmod in a loop under busybox consistently manages to crash without providing a sane flush_kernel_dcache_page() implementation, so, plug in a simple implementation.

* | [NET]: Clone the sk_buff 'iif' field in __skb_clone()Paul Moore2008-01-081-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both NetLabel and SELinux (other LSMs may grow to use it as well) rely on the 'iif' field to determine the receiving network interface of inbound packets. Unfortunately, at present this field is not preserved across a skb clone operation which can lead to garbage values if the cloned skb is sent back through the network stack. This patch corrects this problem by properly copying the 'iif' field in __skb_clone() and removing the 'iif' field assignment from skb_act_clone() since it is no longer needed. Also, while we are here, put the assignments in the same order as the offsets to reduce cacheline bounces. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: David S.

* | [NET]: Add NAPI_STATE_DISABLE.David S. Miller2008-01-081-3/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Create a bit to signal that a napi_disable() is in progress. This sets up infrastructure such that net_rx_action() can generically break out of the ->poll() loop on a NAPI context that has a pending napi_disable() yet is being bombed with packets (and thus would otherwise poll endlessly and not allow the napi_disable() to finish). Now, what napi_disable() does is first set the NAPI_STATE_DISABLE bit (to indicate that a disable is pending), then it polls for the NAPI_STATE_SCHED bit, and once the NAPI_STATE_SCHED bit is acquired the NAPI_STATE_DISABLE bit is cleared. Here, the test_and_set_bit() provides the necessary memory barrier between the various bitops. napi_schedule_prep() now tests for a pending disable as it's first action and won't try to obtain the NAPI_STATE_SCHED bit if a disable is pending. As a result, we can remove the netif_running() check in netif_rx_schedule_prep() because the NAPI disable pending state serves this purpose. And, it does so in a NAPI centric manner which is what we really want. Signed-off-by: David S. Miller <davem@davemloft.net>
* | [NET]: Do not grab device reference when scheduling a NAPI poll.David S. Miller2008-01-081-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is pointless, because everything that can make a device go away will do a napi_disable() first. The main impetus behind this is that now we can legally do a NAPI completion in generic code like net_rx_action() which a following changeset needs to do. net_rx_action() can only perform actions in NAPI centric ways, because there may be a one to many mapping between NAPI contexts and network devices (SKY2 is one example). We also want to get rid of this because it's an extra atomic in the NAPI paths, and also because it is one of the last instances where the NAPI interfaces care about net devices. The one remaining netdev detail the NAPI stuff cares about is the netif_running() check which will be killed off in a subsequent changeset. Signed-off-by: David S. Miller <davem@davemloft.net>

The hardware here seems to lose sync and bits if you tell it to make no changes. This shows up with a real world application. To fix this the driver check for meaningful hardware changes is restored but doing the tests correctly and as a tty layer function so it doesn't get duplicated wrongly everywhere if other drivers turn out to need it.

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.

* Revert "scsi: revert "[SCSI] Get rid of scsi_cmnd->done""Linus Torvalds2008-01-063-15/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

|/ | | | | | | | | | Did not fix the reported issue. Apart from other weirdness this causes a bad link between the TLB flushing logic and the quicklists. If there is indeed an issue that an arch needs a tlb flush before free then the arch code needs to set tlb->need_flush before calling quicklist_free.
