-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am looking for peer review on a paper I need to polish off, which I have just written. I will be cross-posting this to mono's devel list as well; but I have written separate e-mails to avoid noise back and forth. This paper is stored on my personal Web server currently, at the below address.
http://bluefox.kicks-ass.org/stuff/bluefox/misc/vm_twoproc.html Brief summary: Kaffe, Mono, and other systems may execute native code to accomplish certain tasks. For example, Kaffe's classpath may supply some functions using standard libraries like libxml2 or libpng; and C# allows for interoperability service to call native libraries directly, escaping managed mode code and potentially entering vulnerable code. The process described allows the JIT code to be generated and run in a separate process; the main process is executed without runtime code generation, and can be given security restrictions to protect against a diverse set of exploit methods, enhancing security guarantees. - ----------------------------------------------------------------------- Abstract In this paper we present some new ideas for improving the state of the art in Just-in-Time (JIT) compilation. The ideas presented include (1) executing the JIT and generated code in a less restricted security context than the main process; (2) synchronizing the state of memory between the two processes with dynamic address translation; and (3) retaining full compatibility with existing systems and APIs such as not to neccessitate the introduction of new system interfaces. - ----------------------------------------------------------------------- - -- We will enslave their women, eat their children and rape their cattle! -- Bosc, Evil alien overlord from the fifth dimension -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iQIVAwUBRXY+hQs1xW0HCTEFAQIncA//bYRAtfwzMyMXKARdzHgnVUeOZM36BysL HbsSQkhTrGexNDYM5QsbTxsHiSC8MKbnmFcHxMSZE3b3eCVpIymmvoK2bAiC59zm NZDltOa7+lfNQCIFsNWxCDduvXWwvI2MzopBY42e4LYxJnQ0jnx6UBg9FJ+3hyeZ bQx/sc1hzHbxDYOBJcFf+0To8mwIbS/0nN0ReaseHmKQNgd9f7CMmDZ8RFphCbKe W4jHCyDBpSqJe7BhFVeJ+V6JuvNQIfmOyLzkAAojzjGhoGuneRFoG0xi4shNZS4C hnW8h/qJO7gOJpVPzNAisv053RCUmhJLkGtAPDfayocwqf0IzbsFVG6Fn+vROXfG /zvXdoqLLZn4BD/+gOTgUz9hKHm1AnALcO4g76iaI8Hg+xbHCQHI1qgoC7F7SEpa jMGRKKMsHpj7tii69vLjYKSip+2u2oUKY6SIuoOQvxzYkFyGes4lDA9TdpkdvT9R uDm0XC1+D+n78RzfN/xJnGOOIl+nWi5F7wBgwbJfVMNzY/TtsugMBxY8ws8zw1SC hMvdbBrO6k7uzPqxi+ebtt+1R/rQqxeiVxVjHI60AAVP/B0DN4mBq8smiSR0KFwL AtH0hgzGbLGjJuhQ3xdTXVu/6eqou/JB1bdXld4OuzYqH1EO7wvMKKG1hJiMO5c7 dgWLZIgq8mw= =NVO8 -----END PGP SIGNATURE----- _______________________________________________ kaffe mailing list kaffe@kaffe.org http://kaffe.org/cgi-bin/mailman/listinfo/kaffe
