[PATCH] x86_64: Avoid EBDA area in early boot allocator
Based on analysis&patch from Robert Hentosch
Observed on a Dell PE6850 with 16GB
The problem occurs very early on, when the kernel allocates space for the
temporary memory map called bootmap. The bootmap overlaps the EBDA region.
EBDA region is not historically reserved in the e820 mapping. When the
bootmap is freed it marks the EBDA region as usable.
If you notice in setup.c there is already code to work around the EBDA
in reserve_ebda_region(), this check however occurs after the bootmap
is allocated and doesn't prevent the bootmap from using this range.
AK: I redid the original patch. Thanks also to Jan Beulich for
spotting some mistakes.

[PATCH] x86_64: add nmi_exit to die_nmi
Playing with NMI watchdog on x86_64, I discovered that it didn't
do what I expected. It always panic-ed, even when it didn't
happen from interrupt context. This patch solves that
problem for me. Also, in this case, do_exit() will be called
with interrupts disabled, I believe. Would it be wise to also
call local_irq_enable() after nmi_exit()?
[Yes I added it -AK]
Currently, on x86_64, any NMI watchdog timeout will cause a panic
because the irq count will always be set to be in an interrupt
when do_exit() is called from die_nmi(). If we add nmi_exit() to
the die_nmi() call (since the nmi will never exit "normally")
it seems to solve this problem. The following small program
can be used to trigger the NMI watchdog to reproduce this:
main ()
{
iopl(3);
for (;;) asm("cli");

The patch addresses a problem with ACPI SCI interrupt entry, which gets

corrects the code such that SCI IRQ is skipped and duplicate entry is
avoided. Second issue came up with VIA chipset, the problem was caused by
original patch assigning IRQs starting 16 and up. The VIA chipset uses
4-bit IRQ register for internal interrupt routing, and therefore cannot
handle IRQ numbers assigned to its devices. The patch corrects this
problem by allowing PCI IRQs below 16.

[SCTP]: Prevent possible infinite recursion with multiple bundled DATA.
There is a rare situation that causes lksctp to go into infinite recursion
and crash the system. The trigger is a packet that contains at least the
first two DATA fragments of a message bundled together. The recursion is
triggered when the user data buffer is smaller that the full data message.
The problem is that we clone the skb for every fragment in the message.
When reassembling the full message, we try to link skbs from the "first
fragment" clone using the frag_list. However, since the frag_list is shared
between two clones in this rare situation, we end up setting the frag_list
pointer of the second fragment to point to itself. This causes
sctp_skb_pull() to potentially recurse indefinitely.
Proposed solution is to make a copy of the skb when attempting to link
things using frag_list.

[NETFILTER]: H.323 helper: fix use of uninitialized data
When a Choice element contains an unsupported choice no error is returned
and parsing continues normally, but the choice value is not set and
contains data from the last parsed message. This may in turn lead to
parsing of more stale data and following crashes.
