* i386/x86_64: move headers to include/asm-x86Thomas Gleixner2007-10-111-1/+1

* lguest example launcher truncates block device file to 0 length on problemsChris Malley2007-09-261-1/+1
| | | | | | | | | The function should also use ftruncate64() rather than ftruncate() to prevent files over 4GB (not uncommon for a root filesystem) being zeroed.

* lguest: avoid shared libraries mapped over guest memoryRonald G. Minnich2007-08-091-1/+3
| | | | | | | | | | | | | | | | Some versions of ld.so mmap the shared libraries right in over guest memory, so compile lguest statically by default. [ FC7 maps shared libraries very low, where the launcher maps guest's physical memory. Quick fix is to link Launcher static, real fix is for 2.6.24. ] -static is a simple fix. I expect this problem will be more common than we like, as different distro's make different "improvements" to ld.so Signed-off-by: Ronald G.

| | | | | | | | | | | The netfilter code had very good documentation: the Netfilter Hacking HOWTO. Noone ever read it. So this time I'm trying something different, using a bit of Knuthiness.

* link lguest example launcher non-staticRusty Russell2007-07-242-52/+35
| | | | | | | | | | | | | | S.Caglar Onur points out that many distributions don't ship a static zlib. Unfortunately the launcher currently maps virtual device memory where shared libraries want to go. The solution is to pre-scan the args to figure out how much memory we have, then allocate devices above that, rather than down from the top possible address. This also turns out to be simpler.

* lguest: the documentation, example launcherRusty Russell2007-07-193-0/+1168
A brief document describing how to use lguest. Because lguest doesn't have an ABI we also include an example launcher in the Documentation directory.
