Matt, The LLVMCore library provides constant folding automatically. So, when your obfuscated module is read in and the assembler re-creates your constants, the arithmetic is done automatically and the constants are folded. To see where this is done, see lib/VMCore/ConstantFold.cpp Reid. On Thu, 2007-12-13 at 02:22 -0600, Matt Fredrikson wrote: > Hello all, > > I am implementing some

Hello, Matt. > Does anybody know what pass is clobbering my obfuscations? I think this is DAG combiner machinery in the codegenerator itself. Try to provide -fast option to llc. -- With best regards, Anton Korobeynikov. Faculty of Mathematics & Mechanics, Saint Petersburg State University.

Dear OpenSSH team, First of all thanks a lot for your good work on developing such a usable peace of software. Nice job. As you may know, we have some issues using OpenSSH in Iran. Recently the government did some packet filtering on some protocols, including SSH. We don't know what exactly they've done but it appears to be some routing rule that prevents SSH protocol to initiate a

The other thread brought to my attention that only the <email> syntax obfuscates mailto links. Plus, while the entity encoding technique probably fools some scrapers, I doubt it's all that effective. Even Gruber uses the Hivelogic Enkoder [1]. So, what are people using for obfuscation and are you using any scripting or automation (filter that takes a pass before or after Markdown) to

Hi Terry, I take your question to mean how to label distinct rows of a data frame. If that is not your question please clarify. I found the row.match() function in the package prodlim that can be used to solve this. However since your request requires no additional dependencies I borrowed the relevant code from the row.match function. Here is some obfuscated code to provide your answer in one

Hi; This is my 6th day installing my first Postfix/Dovecot installation. The Postfix mailing list indicates I've got the MTA under control so now I'm seeking your help with the MDA.

Hi all, I was trying to implement an obfuscation tool for C-code on the basis of LLVM. I got a prototype of the simple obfuscation transformation which converting control flow graph to something like a state machine. I am not sure I will have time to work on extending further this tool with new transformations like opaque predicates and decided to put here source code I have by now with hope

I'm running Samba 3.0.28a on a CentOS 3.9 box as a member of an AD domain whose PDC is a W2k3 server (Standard x64 R2 SP2). Using wbinfo -u and wbinfo -g I can see domain users and groups from the CentOS box, but getent (passwd|group) fails to display them. The nsswitch is setup correctly, as far as I can tell. When I tail -f the samba log file during a getent query, I see that winbindd is

is there a way to replace unkown action error with a pretty 404 page ? I set the ErrorDocument 404 in .htaccess, however when someong goes to http://www.mysite.com/bogus i would like it to show a 404 error instead of just "Uknown action". Is this possible with a rescue or something? adam -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, I want to use the dsmark, but it always says: "unkown qdisc", although I have enabled it (y in Network options), and I have my kernel recompiled. I am using SuSE 8.1, 2.4.20 Kernel, tc available at the HTB site (with already precompiled HTB queue). Can anybody find the problem? thx _________________________________________________________________ MSN 8 helps eliminate e-mail

Hello, I''ve got xen installed on a box running Fedora Core 6. In addition I''m running a Windows 2003 server as a domU. Everything work fine and I am quite satisfied with the setup. However, in win 2003''s device manager there is a unknown PCI device that I not able to find a suitable driver for. Windows update can''t find one either. Is there a way to find what

Hey, another question. I am having problems with my call files. Whenever I drop one into the outgoing folder, I get an "unknown keyword" error for each line in the file. This is what I have my file as right now.

Hi there, I build a samba 4.0.11 on a Debian Wheezy from source, joined a existing AD (samba works with internal dns) and have this smb.conf: ======= # Global parameters [global] workgroup = DOMAIN realm = DOMAIN.local netbios name = SAMBA1 server role = active directory domain controller allow dns updates = nonsecure dns recursive queries = yes

Hi all, suppose I've got a vector y with some data (from a repeated measure design) observed given the conditions in f1 and f2. I've got a model with two unknown fix constants a and b which tries to predict y with respect to the values in f1 and f2. Here is an exsample # "data" y <- c(runif(10, -1,0), runif(10,0,1)) # f1 f1 <- rep(c(-1.4, 1.4), rep(10,2)) # f2 f2 <-

I'd like to know if there is any known project doing obfucated code generation or software watermarking in LLVM. The [obfucation/software watermarking] in machine instruction level usually requires to insert dead code, constant "unfolding", computationally intensive "opaque predicate", redundant calculation, duplicated calculation, etc, which all make the program

I've written down a simple yet a bit obfuscated perl script to put samba logs on a MySQL database, inspired on a little howto i found some time ago googleing around. It works by reading logs from a fifo instead of parsing actual log files, but allows to create sparse files too. Log lines are then parsed by matching to a regexp to extract desired values then inserting the record on mysql. It
