Xen Patches README ------------------ These patches are intended to be stacked on top of genpatches-base. Many of the patches included here are swiped from various sources which use their own four digit patch numbering scheme, so we are stuck with five digits to indiciate the source for easier tracking and re-syncing. Numbering --------- 0xxxx Gentoo, not related to Xen. (in case we pull something from extras) 1xxxx XenSource, upstream Xen patch for 2.6.18 2xxxx Redhat, we use their Xen patch for >=2.6.20 3xxxx Debian, we use their security fixes for 2.6.18 5xxxx Gentoo, Xen and other fixes for Redhat and/or Debian patches.

(closes: Debian #440127) 30042_reset-pdeathsig-on-suid-upstream.patch Update fix for CVE-2007-3848 with the patch accepted upstream (formerly 30013_reset-pdeathsig-on-suid.patch) 50001_make-install.patch Handle make install in a semi-sane way that plays nice with split domU/dom0 kernels. 50002_always-enable-xen-genapic.patch Compile fix for non-SMP (UP) kernels.
