This broke packages that needed a target Python at build-time.
Instead, change it from defined/undefined to yes/no/tool. Most cases
of defined used `yes' anyway; fix the few stragglers do that instead.
New case `tool' is for TOOL_DEPENDS rather than buildlink3.
This integrates fixes for all vulnerabilities which were patched
in pkgsrc before.
Among many bug fixes and improvements (around 50 since Xen 4.1.4):
* ACPI APEI/ERST finally working on production systems
* Bug fixes for other low level system state handling
* Support for xz compressed Dom0 and DomU kernels

changes:
-fixes for many vulnerabilities (were mostly patched in pkgsrc)
-bug fixes and improvements (almost 100 since Xen 4.1.3). Highlights are:
-A fix for a long standing time management issue
-Bug fixes for S3 (suspend to RAM) handling
-Bug fixes for other low level system state handling
pkgsrc note:
fixes for CVE-2012-5634 (interrupt issue on IOMMU systems)
and CVE-2012-6075 (oversized packets from e1000 driver)
are already included
also add security patches from upstream (for CVE-2012-3497, no patches
are available yet)
changes:
-fixes for vulnerabilities were integrated
-many bug fixes and improvements, Highlights are:
-Updates for the latest Intel/AMD CPU revisions
-Bug fixes for IOMMU handling (device passthrough to HVM guests)
approved by maintainer
* Security fixes including CVE-2011-1583 CVE-2011-1898
* Enhancements to guest introspection (VM single stepping support for very fine-grained access control)
* Many stability improvements, such as: PV-on-HVM stability fixes (fixing some IRQ issues), XSAVE cpu feature support for PV guests (allows safe use of latest multimedia instructions), RAS fixes for high availability, fixes for offlining bad pages and changes to libxc, mainly of benefit to libvirt
* Compatibility fixes for newer Linux guests, newer compilers, some old guest savefiles, newer Python, grub2, some hardware/BIOS bugs.
It uses -nostdinc and tries to use #include <stdarg.h> through
a local copy of stdarg.h, which can't work.
Fixed this by putting the relevant builtin stdarg definitions for
NetBSD in the local copy.
guests operating systems on a single machine. Guest OSes (also called "domains"
)
require a modified kernel which supports Xen hypercalls in replacement
to access to the physical hardware. At boot, the xen kernel is loaded
along with the guest kernel for the first domain (called domain0).
domain0 has privileges to access the physical hardware (PCI
and ISA devices), administrate other domains and provide virtual
devices (disks and network) to other domains.
This package contains the Xen4 kernel itself.
Release notes:
The Xen team is pleased to announce the release of Xen 4.1.
The result of nearly 12 months of development, new features include:
* A re-architected and improved XL toolstack replacing XM/XEND
* Prototype credit2 scheduler designed for latency-sensitive workloads and
very large systems.
* CPU Pools for advanced partitioning.
* Support for large systems (>255 processors)
* Support for x86 Advanced Vector eXtension (AVX).
* New Memory Access API enabling integration of 3rd party security
solutions into Xen virtualized environments.
* Many IOMMU fixes (both Intel VT-d IOMMU and AMD IOMMU).
* Many toolstack and buildsystem fixes for Linux and NetBSD hosts.
* Thirdparty libs: libvirt driver for libxl has been merged to upstream
libvirt.
* HVM guest PXE boot enhancements, replacing gPXE with iPXE.
* Even better stability through our new automated regression tests.
