Fix code which finds the default interface if there are static routes.
The current code will break if there are multiple scope global routes
since the "ip route list default" command doesn't use "default" as a
filter, and will output multiple devices which breaks the rest of the
script.
Also make the vif/xenbr/eth naming consistent, i.e. if your default
network interface is eth1, you get vif1 and xenbr1.

Instead of just having the bootloader config sxp replace anything else,
merge with given values. This will allow a bootloader to not have to
specify everything which is useful for bootloaders other than pygrub.
Fix injection of guest faults resulting from failed injection of a
previous event. We enter an infinite loop if the original failed
injection cannot be fixed up by Xen (e.g., because it's not a shadow
pagetable issue).
The RHEL4 HVM guest hang issue was actually a side effect of
change-set 9699. In the rhel4 guest hang rc.sysinit init-script was
calls kmodule program to probe the hardware. The kmodule uses the kudzu
library call probeDevices(). For probing the graphics hardware in the
vbe_get_mode_info() function, sets up the environment and goes into the
vm86 mode to do the int x10 call. For returning back to protected mode
it sets up a int 0xff call. At the time of calling the int 0xff the
guest process pages were not filled up. And it was causing an infinite
loop of vmexits with the IDT_VECTORING_INFO on the int 0xff instruction.
The reason for the infinite loop is changeset 9699. With that
the guest page fault was always getting overridden by the int 0xff gp
fault coming from the IDT_VECTORING_INFO. With the attached patch if VMM
is injecting exceptions like page faults or gp faults then
IDT_VECTORING_INFO field does not override it, and that breaks the
vmexit infinite loop for the rhel4.

Fix python pciif script to reference correct 2.0 compatibility variable.
In the Xen 2.0.x compatibility section of xend (where we try to parse

Add new networking infrastructure to Xm-Test. The goal is to make
creating domains with networking very easy. This patch:
1) Adds new XenDevice class, with the XenNetDevice subclass. These
classes represent devices for xm-test and are tied to XenDomains.
This can eventually be used for block devices as well. Currently,
devices must be added to domains prior to starting the domain. The
attach and detach needs to be handled.
2) Adds a new NetConfig class to handle configuring the network
environment in which the tests run. This patch only handles ranges
of IPs in a bridged environment. DHCP needs to be added as well as
handling NAT and routed environments.
3) Modifies XenDomain class to handle XenDevices.
4) Adds new configuration options for defining a range of IPs, their
network address, and their netmask.
5) Removes the old Network.py and Network class.
6) Modifies the existing tests to use the new infrastructure.
7) Adds some documentation to help creating domains.

Second step toward a new network infrastructure, move XmConsole to be

First step to network infrastructure, add a type to XenDomain to identify

Introduce some finer-grained locking to prevent calling
copy_from/to_user while preventing interrupts and fix allocation of
memory from within a task and other issues.
Xm-tests 01_memset_basic_pos.test and 03_memset_random_pos.test start
domUs with 64MB of memory,
and assume that all of that memory is available in the domU. They then
perform various xm memset tests
based on the assumed starting conditions.
When netback & blkback are comiled into the domU kernel, they eat about
5MB. This mismatch will cause
01_memset_basic_pos.test to fail every time. 03_memset_random_pos.test
will probably fail, but can
pass with some lucky numbers from the random number generator.
This patch changes both tests to read the starting memory allocation from
the balloon driver in the domU.
Balloon driver should hijack the ->lru list field rather than
adding another list field to every page structure. Signed-off-by: Keir Fraser <keir@xensource.com>
This patch changes to format in which EIP is printed to be consistent on 64-bit regardless of whether the addresses
leading bits are set or clear. It additionally changes the formatting so that trailing spaces are avoided, and it
suppresses the printing of empty records. It also prevents combining records with identical EIP but from different
domains.
It further changes the type of some variables from plain int to unsigned int, as that is yielding more efficient code
on x86-64 (signed 32-bit array indices require explicit sign extension, whereas in most cases an extra copy can be
avoided when the index type is unsigned, since all 32-bit operations already zero-extend their results).
This patch conditionalizes some output from perfc_printall(), thus making relevant information more compact and easier
legible. It additionally changes the formatting so that trailing spaces are avoided.

Debugging Xend with XEND_DAEMONIZE set to False doesn't work as
expected. Xend actually creates two children and the XEND_DAEMONIZE
flag only prevents one of the children from being created. This
patch causes none of the children to be created. With this patch,
Xend functionality is performed in the process executed from the
command line (i.e., /usr/sbin/xend). This patch makes it possible to
debug Xend with pdb.

Instead of relying on xm create to always run the bootloader, make sure
we run it if we get into domain creation with a bootloader set but no
image. This could happen if someone creates a domain config via the
XML-RPC or sxp interfaces.
The features for a domain are more a property of the domain than the
image. Move them into the domain info so that the image is just the
pieces needed for booting (eg, kernel + initrd + args)

This patch adds the ability to have restricted write access to some
of the structures on the capability list. Specifically, this patch adds
support for reading data through the Vital Product Data capability
structure and for manipulating power management of a card. A driver
domain is not allowed to enable Power Management Events (the PME trace
may be shared across devices in many domains), but it can put a device
in its control to sleep or query it for power usage statistics. This
code could possibly be expanded in the future to add support for AGP,
PCI-X, and MSI/MSIX (all of which are controlled through structures on
the capability list).
This patch also corrects some formatting issues in the PCI backend and
adds some comments to the code regarding permissive mode.
This patch addresses CVE-2006-1056 (information leak from
fxsave/fxrstor on AMD CPUs) and also adjusts 64-bit handling so that
full 64-bit RIP/RDP values get saved/restored. More fine-grained
handling may be needed if 32-bit processes are expected to properly
see their selectors (native Linux doesn't currently do that either,
but there is a patch to adjust it there).
