similar to: [LLVMdev] Modifying address-sanitizer to prevent threads from sharing memory

Hi llvm-dev! I'm writing my master's thesis on sandboxing/isolation of plugins running in a multithreaded environment. These plugins run in a real-time environment where the cost of IPC/context switching and being at the scheduler's mercy is not an option. There can be a lot of plugin instances running and all have to perform some computations and return the result to the main thread

Thanks! I'll try that. In order to avoid starting a new thread, let me ask you the next question. One of the shared libraries I load calls strtol and msan fails to intercept it. Why would this be? The library seems to be otherwise implemented. One of the potential culprits I saw is that strtol is marked as strong in libc. Is there any workaround? Keno On Thu, Apr 9, 2015 at 3:00 PM, Evgeniy

Hi everyone, I ran into a false positive with memory sanitizer due to it not intercepting dlinfo. I tried to get started on writing such an interceptor, but dlinfo seems like an extraordinarily difficult function to intercept. The three considerations that I would like somebody to look at are: 1) How do we get the enum values to decide what kind of pointer dlinfo is getting. Ideally we'd

In what fashion does the encoder 'blowup' when passed a frame of zeroes to encode?

Look in the March 2004 archive for the thread: "Real Player and Icecast 2". I don't get the blowup they describe, but we do get some type of transient noise every few seconds. This occurs on all Windows PCs that we've tried the current version of Real Player with our MP3 streams.

Okay, you've answered part of my question, which is "What value equals silence?". I assume then that a (decoded) frame of silence would be a buffer the size of my frame (320 bytes) full of 0's. Passing this frame (a frame of all 0's) through the encoder causes it to blowup though.. In response to your answer below, I don't think I want to overwrite the decoded

Hi all, I am a fourth year EE bachelors student who is very interested in compilers. I have taken the only compilers course offered in my school and did an independent study with my CS professor. Although I'll begin to work in a couple of months, I definitely want to pursue my interest in compiler design and optimization as a PhD in the future. I am very interested in the z3 SMT solver

Hello I am willing to make changes in Address Sanitizer for experimentation. But as I am a naive user I am confused with the fact that if I make changes to Address Sanitizer do I have to rebuild the whole LLVM. Could somebody please help me figure out a way in which I can make changes to address sanitizer and do not have to compile the whole LLVM. Aayushi Agrawal -------------- next part

Thank you for the response. Suppose I want to make changes in the LLVM part of Address Sanitizer. Is there still a way to test the changes made to address sanitizer as a standalone. Also can a pass be run after Address Sanitizer Pass is ran, where I can access the variables created by address sanitizer [LLVM Code] so that I avoid making changes directly to the address sanitizer?

I'm having trouble finding any documentation of the sanitizers, especially the leak checker -- apparently because of the move from code.google.com to github. Every doc has a link for "more information" which goes to code.google.com which just redirects to github and points to a placeholder doc that says lots of links are broken. I haven't found the docs using any google-fu or

Hi, I followed the how-to from http://www.alcatelunleashed.com/viewtopic.php?f=44&t=840 All works fine except for Asterisk->Alcatel calls. Actually, calls from Asterisk to analog extensions on the Alcatel work. However, calls from Aserisk to digital extensions on the Alcatel 4400 do NOT work. I get this error in the Asterisk log: -- Executing Dial("SIP/4053-0823dd48",
