   data fails.

3) We 'remembered' the MSI number using a singleton in the
   struct device archdata area, this doesn't work for MSI-X
   which can cause multiple MSIs assosciated with one device.

Hugh Dickins [Fri, 31 Aug 2007 03:26:50 +0000]
fix maxcpus=1 oops in show_stat()

Alexey Dobriyan reports that maxcpus=1 is still broken in 2.6.23-rc4:
if CONFIG_HOTPLUG_CPU is not set, x86_64 bootup oopses in show_stat() -
for_each_possible_cpu accesses a per-cpu area which was never set up.

Alexey identified commit 61ec7567db103d537329b0db9a887db570431ff4
(ACPI: boot correctly with "nosmp" or "maxcpus=0") as the origin;
but it's not really to blame, just exposes a bug in 2.6.23-rc1's commit
8b3b295502444340dd0701855ac422fbf32e161d (Especially when !CONFIG_HOTPLUG_CPU,
avoid needlessy allocating resources for CPUs that can never become available).

rc1's test for max_cpus < 2 in start_kernel() wasn't working because
max_cpus was still NR_CPUS at that point: until rc4 moved the maxcpus
parsing earlier.  Now it sets cpu_possible_map to 1 before allocating
all possible per-cpu areas; then smp_init() expands cpu_possible_map
to cpu_present_map (0xf in my case) later on.

rc1's commit has good intentions, but expects cpu_present_map to be
limited by maxcpus, which is only the case on i386.  cpus_and(possible,
possible,present) might be good, but needs an audit of cpu_present_map
uses - there may well be assumptions that any cpu present is possible.

So stay safe for now and just revert those #ifndef CONFIG_HOTPLUG_CPU
optimizations in rc1's commit.

[POWERPC] spufs: Don't call spu_run_init from spu_reacquire_runnable

This fixes a major bug which was happening when a SPU thread advances
its execution right after being restored to a SPU.  A potentially
outdated NPC value was being (re)written to the SPU.

So, spu_run_init, in this case, was either not doing anything relevant,

When a process writes into the inbound spu mailbox (wbox) while the

[POWERPC] spu_manage: fix spu_unit_number for celleb device tree

This fixes a regression introduced with 2.6.23-rc4 after on some
confusion about the device tree interfaces.

IBM QS21 device trees provide "physical-id", so we changed the code to
run on that and remain compatible with all IBM machines.

However, the Toshiba Celleb device tree provides the "unit-id" property,
which was in the Linux code, but never used in this way on IBM hardware.

Legacy device tree used the reg property for the physical id of an spe.
This patch fixes find_spu_unit_number to look for the spu id in that order.
The length is checked to avoid misinterpretation in case the attributes
unit-id or reg do not contain the id.

[VLAN/BRIDGE]: Fix "skb_pull_rcsum - Fatal exception in interrupt"

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?

Nick Bowler [Wed, 22 Aug 2007 19:33:51 +0000]
[IPSEC] AH4: Update IPv4 options handling to conform to RFC 4302.

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.
