I re-wrote the compile script to build klibc (cleaning up how I do it, and how to find the source tarballs). It seems to be compiling fine. I tried several of the commands in usr/utils/static and most one. However, the sleep command fails in a strange way (EINVAL on execve): ================================================================ faraday/phil /home/phil/klibc-project-0 581> strace -ftt -s 96 klibc-1.5.18/usr/utils/static/true 07:33:08.185542 execve("klibc-1.5.18/usr/utils/static/true", ["klibc-1.5.18/usr/utils/static/true"], [/* 38 va...

The former is lighter weight and easy to configure. The downside is that system calls route to the host system. That can be useful if, for example, the executable invokes llvm-symbolizer. While

Hi Evgeniy, This fix causes me trouble in the emulator because of the execv(argv[0]): http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20140217/205359.html Instead using setrlimit from within the C++ code, can you set the stack limit using ulimit on the RUN lines? Also, should this test be moved to the Posix or Linux directory? Thanks, Greg

I like that idea. How

Hello, For a key exchange algorithm I'm working on, I would like to keep a little bit of shared state between the main server process and the processes that clients connect to. So far, I'm considering mmap for the purpose. But I cannot figure out where I need to put the mmap initialization call, where it would be called at server startup (before any fork()s/exec()s), and never again.

...tfs appliance with euid:egid = 36:36, which is required to write to an NFS target using root_squash. Since the update to use an febootstrap cached appliance, this causes an error on startup as the cached files are owned by root, but the cache directory is owned by 36:36. The reason for this is that execve() resets euid and egid to uid and gid respectively, so when febootstrap-supermin-helper is executed, it runs as root:root. The cache directory, however, is created by libguestfs directly without exec()ing another program, so it has the correct ownership. This patch fixes this issue by setting real...

....uk I've encountered a problem similar (or identical to) 967, but in a modern version, and with more details. I found a problem where executing ssh with a command (`ssh host date` would often hang. Debugging sshd I found that do_exec_no_pty() calls do_child() after the fork(), and that then execve()s. That execve doesn't appear to complete, and the parent doesn't appear to return from the fork.
