If the stack pointer is 0xc057a000, then the first stack page is at 0xc0579000 (the stack pointer is decremented before use). Not calculating this correctly caused guests with CONFIG_DEBUG_PAGEALLOC=y to be killed with a "bad stack page" message: the initial kernel stack was just proceeding the .smp_locks section which CONFIG_DEBUG_PAGEALLOC marks read-only when freeing.

Without this, we get qla2xxx complaining about "ISP System Error". What's happening here is the firmware is detecting a Xfer-ready from the storage when in fact the data-direction for a mode-select should be a write (DATA_OUT). The following patch fixes the problem (typo). Verified by Brian, as well.

Fix bogus DEBUG_PREEMPT warning on x86_64, when cpu brought online after bootup: current_is_keventd is right to note its use of smp_processor_id is preempt-safe, but should use raw_smp_processor_id to avoid the warning.

Sigh. Again an ACPI assault on the Thinkpad's Fn+F4 to suspend to RAM. The default and text for CONFIG_THINKPAD_ACPI_INPUT_ENABLED were fixed in -rc3, but now commit 14e04fb3 ("ACPI: Schedule /proc/acpi/event for removal") introduces the ACPI_PROC_EVENT config entry, and defaults it to 'n' to disable it again. Change default to y, and add comment to make it clearer that n is for future distros.

Commit 61ec7567 ('ACPI: boot correctly with "nosmp" or "maxcpus=0"') broke 'maxcpus=' handling on x86[-64]. maxcpus=N is now having no effect on x86_64, and freezing bootup on i386 (because of inconsistency with the separate maxcpus parsing down in arch/i386, I guess). That's because early_param parsing is a little different from __setup parsing, and needs the "=" omitted: then it seems to work as the original commit intended (no mention of IO-APIC in /proc/interrupts when maxcpus=0).

While debugging issues with the VDS server I made the driver use partition 2 to get at the whole disk since this is the "whole disk" partition in the Sun disk label. We really should use slice 0xff which really means the whole physical disk in the VIO disk protocol. Otherwise things won't work well on a disk image that doesn't have a proper disk label on it.

I tried to preserve bridging code as it was before, but logic is quite strange - I think we should free skb on error, since it is already unshared and thus will just leak. Herbert Xu states: > + if ((skb = skb_share_check(skb, GFP_ATOMIC)) == NULL) > + goto out; If this happens it'll be a double-free on skb since we'll return NF_DROP which makes the caller free it too. We could return NF_STOLEN to prevent that but I'm not sure whether that's correct netfilter semantics. Patrick, could you please make a call on this?

In testing our ESP/AH offload hardware, I discovered an issue with how AH handles mutable fields in IPv4. RFC 4302 (AH) states the following on the subject: For IPv4, the entire option is viewed as a unit; so even though the type and length fields within most options are immutable in transit, if an option is classified as mutable, the entire option is zeroed for ICV computation purposes. The current implementation does not zero the type and length fields, resulting in authentication failures when communicating with hosts that do (i.e. FreeBSD). I have tested record route and timestamp options (ping -R and ping -T) on a small network involving Windows XP, FreeBSD 6.2, and Linux hosts, with one router. In the presence of these options, the FreeBSD and Linux hosts (with the patch or with the hardware) can communicate. The Windows XP host simply fails to accept these packets with or without the patch. I have also been trying to test source routing options (using traceroute -g), but haven't had much luck getting this option to work *without* AH, let alone with.
