The sshd server has what I think is a serious flaw. There appears to be no way to turn off remote command execution. (someone please correct me if I am wrong). We have a server which uses a chroot jail, and rbash to severely limit what users can do on our system. The remote command bypasses all of that. ie. ssh user at host cat /etc/passwd will display the password file for the live system

...1.2_i386.deb, with just the one chroot patch applied.) I thought that perhaps the chroot is preventing sshd from finding the sshd_config file, thus causing a runtime option to default back to "SELinux support enabled", but the sshd_config does not say anything about SELinux: root at cst2:/etc/ssh# grep -i selinux * root at cst2:/etc/ssh# This observation also concurs with Alexandre's report, because he said this failure is only for "accounts where the new ChrootDirectory option is active". I know C and I'd be happy to work on a fix, but I haven't c...

Hi all, I came across something that seems to be a bug in the dragonegg option that emits LLVM IR. ¿Can anybody reproduce the error, or see what's wrong? ¿Should I post it somewhere else in case it's really a bug? Thanks ahead! With this simple program: * #include <stdio.h> #include <string.h> int main(int argc, char** argv){ char a[8] = "aaaaaaa";

Right, conditionals like "cst1 < cst2" will certainly be folded to true or false. Also "undef < X" will be folded to undef by the SCCP pass. -Chris -- http://nondot.org/sabre/ http://llvm.org/
