Package: xserver-xfree86 Version: 4.3.0.dfsg.1-8 Severity: normal background: AMD64 NX support works in 32bit and 64bit mode. It adds an exec permission bit to PAE page tables, so PROT_READ is separate from PROT_EXEC. Since it only works with 3rd level page tables, not plain x86 ones, it only works with highmem64GB kernels (in which case it's on by default).
see http://lists.debian.org/debian-amd64/2004/09/msg00393.html http://kerneltrap.org/node/view/3240/9418 Summary: noexec means memory pages have to be mapped with PROT_EXEC if you want to run code in them. Stack and heap are non-executable by default. Apparently ELF executables can specify executability of things... The bug is that X segfaults on noexec kernels, but not when I boot with noexec=off. This happens with the radeon driver, and with the ati driver (on a dual Opteron Tyan board with built-in mach64 video.) Please make the i386 xserver-xfree86 package work on NX systems. (The kernels that Debian ships aren't compiled with highmem64, so this will only affect people who recompile their kernels, not everyone who installs Sarge on an AMD64. In that case this bug would be "important".) -- Package-specific info: ...
