Greetings LLVM Devs! I am a PhD student in the Secure Systems and Software Lab at UC Irvine. We have been working on adding randomness into code generation to create a diverse population of binaries. This diversity prevents code-reuse attacks such as return-oriented-programming (ROP) by denying the attacker information about the exact code layout. ROP has been used is several high-profile recent

I was browsing through the SAMBA workgroups defined here: E51-CAE, E51-WAAS, etc... everything looked fine (well, with the exception of subnet browsing) until I displayed the properties of the machines in the workgroups. Select a SAMBA host, right-click on the hostname and select 'Properties' from an NT4 machine displays the domain as "E51"; everything from the dash onward

This RFC describes pagerando, an improvement upon ASLR for shared libraries. We're planning to submit this work for upstreaming and would appreciate feedback before we get to the patch submission stage. Pagerando randomizes the location of individual memory pages (ASLR only randomizes the library base address). This increases security against code-reuse attacks (such as ROP) by tolerating

That breaks the whole IR idea of using alloca to allocate/denote space for local variables, and then optimize those into SSA values when optimization proves that is OK. Also, for a lot of things, that attribute is simply impossible to implement. Any value that is live across a call needs to be spilled to memory. You cannot put an unspillable value in a callee preserved register, because you

Hi all, The slides we used on "CGO MCLinker and LLVM Tutorial" are now available on the MCLinker website: http://code.google.com/p/mclinker/wiki/2013CGOTutorial Enjoy! - The CGO Tutorial on MCLinker and LLVM 2013 committee

Hello, when i use libguestfs to ceph rbd by golang, but there has panic: panic: runtime error: cgo argument has Go pointer to Go pointer goroutine 1 [running]: guestfs.(*Guestfs).Add_drive.func11(0xc000010028, 0xcda6a0, 0xc0000d6000, 0xc000090280) /opt/gopath/src/guestfs/guestfs.go:1440 +0xc2 guestfs.(*Guestfs).Add_drive(0xc000010028, 0x7ffd4b5d67ff, 0xd, 0xc00008d9d8, 0x0)

I could understand a TLB hit if functions that originally happened to be on the same page were spread across many pages, raising the iTLB footprint for a given loop, etc. (reduced spatial locality). For pagerando, since we're splitting on 4k page boundaries and can keep spatial locality (or attempt to improve it), I'm not sure that TLB misses will be a large factor. I expect that the

Dear LLVM user and developer, We get a chance to give a tutorial on LLVM and MCLinker. The tutorial will be co-located with CGO 2013 on Feb. 24 (Sunday morning) in Shenzhen, China. If you are also interesting in these topics, welcome to join the tutorial! Here is a website of the tutorial: http://code.google.com/p/mclinker/ We're also looking for additional presenters to share a

Dear useRs, The FD package is intended for ecologists interested in functional diversity (FD). It measures different functional diversity indices from multiple traits (any type of traits). The first version of FD (1.0-0) is now available on CRAN: http://cran.r-project.org/web/packages/FD/ The main functions of FD are: dbFD: Compute different multidimensional FD indices gowdis: Gower

Dear List, I can'f figure how to add point labels in the next plot (example from ?taxondive help page, from vegan package): library(vegan) data(dune) data(dune.taxon) taxdis <- taxa2dist(dune.taxon, varstep=TRUE) mod <- taxondive(dune, taxdis) plot(mod) The points in this plot are diversity values of single sites, and I'd like to add a label to each one. The plot command don't
