I notice that in 2.6.9 and up, UML is built-in, and that said built-in UML has SKAS support options. Does this mean that these kernels also have the SKAS patch built-in if compiled without ARCH=um? -Robin -- http://www.digitalkingdom.org/~rlpowell/ *** http://www.lojban.org/ Reason #237 To Learn Lojban: "Homonyms: Their Grate!"

No. However, starting with the 2.6.13 UML, there is a skas0 mode, which resembles normal skas3 mode, but requires no host kernel changes. UML, if built with CONFIG_MODE_SKAS, and run on an unmodified host, will run in skas0 mode, and this is now the recommended way to go. Jeff |

It would be really nice if this was explained on http://user-mode-linux.sourceforge.net/skas.html Is there a SKAS0 UML binary download available anywhere? -Robin -- http://www.digitalkingdom.org/~rlpowell/ *** http://www.lojban.org/ Reason #237 To Learn Lojban: "Homonyms: Their Grate!"

Checking for the skas3 patch in the host...not found UML running in SKAS0 mode Checking PROT_EXEC mmap in /tmp...OK http://pwp.etb.net.co/arhuaco/uml/ If you try the kernel, let me know if it works.
