If you compile this with optimizations, then the 'canary()' function should be totally inlined into the 'main()' function. In that case, the cost of the stack protectors will be very small compared to the loop. -bw On Mar 9, 2012, at 2:52 AM, Job Noorman <jobnoorman at gmail.com> wrote: > I have a question about the performance of the implementation of the stack >

I have a question about the performance of the implementation of the stack protector in LLVM. Consider the following C program: ===== void canary() { char buf[20]; buf[0]++; } int main() { int i; for (i = 0; i < 1000000000; ++i) canary(); return 0; } ===== This should definately run slower when stack protection is enabled, right? I have measured the runtime of

Ok, so I'm slowly figuring out what a factor is, and was able to follow the related thread about finding a mode by using constructs like my_mode = as.numeric(names(table(x))[which.max(table(x))]) Now, suppose I want to keep looking for other modes? For example, Rgames> sample(seq(1,10),50,replace=TRUE)->bag Rgames> bag [1] 2 8 8 10 7 3 2 9 8 3 8 9 6 6 10 10 7 1

Hi all, I want to implement the Xor random canary, so I have to get the return address in the prologue and epilogue of the function. In the prologue of the function, before I insert into the canary on the stack, I can get the return address by: ConstantInt* ci = llvm::ConstantInt::get(Type::getInt32Ty(RI->getContext()), 0); Value* Args1[] = {ci}; CallInst* callInst =

Hi all, I am master student in Edinburgh, UK. I am doing my MSc project with LLVM compiler and I have to modify LLVM to implement the StackGuard with a XOR random Canary. However, I am not familiar with LLVM. My problem is that I want to XOR the random canary word with the return address which are both 32 bits. I found a method called SimplifyXorInst(Value *, Value *, const TargetData

Hi all, How to XOR the return address on the stack with a canary word both are 32 bits? Is there a method to implement it? Thank you. Ying -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.

Can zfs send utilize multiple-streams of data transmission (or some sort of multipleness)? Interesting read for background http://people.planetpostgresql.org/xzilla/index.php?/archives/338-guid.html Note: zfs send takes 3 days for 1TB to another system Regards, Jignesh

All, I just had a power failure that caused me a little drama. This spurred me into trying to get NUT up on my cyberpower 1500 again. For about 6 months I tried to get it to work with the new power panel drive with no luck. Today I removed all the old files for NUT and installed the newest version I could find (2.4.3) and it works perfectly now with my UPS. Hopefully now I

All, I am toying with an idea of using an AGI to be able to 'call' my phone, or phones, in case of severe weather warnings. I have been tinkering with a script that reads from weather underground for the forecast, based off a PHP version of a weather AGI I found on the net. It seems rather trivial to have the AGI as a script, that does nothing unless a condition is met, and

Hi, I'm running a webradio on our brandnew CentOS 5.1 database server. (The main purpose of this radio is fun, sure, but it's also a bit like a canary in a coalmine...) It's based on Icecast, MPD and NCMPC and works great. I'm configuring the server remotely via SSH, no X. Is there any commandline utility to edit ID3 tags? Cheers, Niki

Hi, Would it be acceptable to patch make_file() in flist.c to ignore any ENODEV's and not mark them as io_error=1? In afs, a mountpoint to a volume which does not exist gives an ENODEV. As such, it can't be copied, so should (or could) just be ignored? The io_error isn't terminal, but it does disable the delete function and you end up with an exit code of 23. regards |<evin

Hi, I've just created a small directory as an example, it holds a file and two symlinks that don't point to anything, and another symlink going nowhere in a subdirectory. rsync (2.5.5) is happy to copy these but produces an error. I can't see why it considers this an error? It's not even aborting after it first encounters this 'error'. $ ls -lR /var/tmp/rsync.test

With the increased number of "brute force" login attempts against port 22, I am concerned that an intruder may actually stumble accross a valid user/pass combination. To combat this, I would like to request an sshd_config option that would cause the running sshd parent process to keep track of login failures by IP address. If there are more than X number of login failures for a

I am running into an issue with rsync that I need some help with. When syncing large files (e.g. 1GB), the rsync algorithm creates a temporary 1GB file and then renames it when the transfer is finished. The issue I am running into is if the two large files have very few differences between them, the bottleneck is creating the 1GB temporary file on the target box. This process takes several
