These days, sshd.c has: static void grace_alarm_handler(int sig) { ... if (getpgid(0) == getpid()) { signal(SIGTERM, SIG_IGN); killpg(0, SIGTERM); } sigdie(...); } however (really) old BSDs do not have getpgid(). They do have getpgrp(), which does what we want here. The question is what to do if we have neither: return the pid (a...

...rocess, let''s say a rake task, the rake task gets killed because it gets the SIGTERM signal. In the class StarStop we have: def kill_process arg_pid_file pid = nil pid = File.open(arg_pid_file, "r") { |pid_handle| pid_handle.gets.strip.chomp.to_i } pgid = Process.getpgid(pid) puts "Stopping BackgrounDRb with pid #{pid}...." Process.kill(''-TERM'', pgid) File.delete(arg_pid_file) if File.exists?(arg_pid_file) puts "Success!" end What I did was, that instead of killing pgid, I''m doing a system call and k...

When using multicore-forking of the parallel package, is it possible for a child process to know that it is a fork? Something like: parallel::mclapply(1:10, FUN = function(i) { test_if_running_in_a_fork() }) I'm looking into ways to protect against further parallel processes (including threads), which not necessarily are created via the parallel:mc* API, are being spawned off recursively.

...this question as I am likely not skilled enough to answer this. For me it looks like there are currently two cases of using syscalls in klibc: 1. Exporting stubs directly: For many syscalls, automatically generated stubs are directly exported as symbols for use by the linker. Examples: setpgid()/ getpgid() 2. Using stubs internally for implementing public function. The auto generated stub is used as base for implementing a C library function. Example: exit() For both cases, the code for the individual stubs is auto generated using a perl script (with an arch specific "plugin"). All gene...

Hi, I have an application which is dying horrible deaths (i.e. segmentation faults) in mid-flight, in production... And of course, I should fix it. But while I find and fix the bugs, I found something I think should be different - I can work on submitting a patch, as it is quite simple, but I might be losing something on my rationale. When Mongrel segfaults, it does not -obviously- get to clean

...d; SEXP is_forked(){ return ScalarLogical(R_isForkedChild); } But that won't be allowed on CRAN: * checking compiled code ... NOTE Found non-API call to R: ?R_isForkedChild? Compiled code should not call non-API entry points in R. Another method would be to look at getppid(2) and getpgid(2) to lookup the parent-id and group-id of the current process and test if it matches that of the (parent) R process. If you are only interested in limiting further parallelization within the fork, perhaps you can simply use parallel::mcaffinity to restrict the forked process to a single core.

I think the question was how users would know that the policy allowed access, as he was printing rules affecting httpd_t's file read access, and looking for

libkeyutils is used by the keyctl command which is required for loading keys into the kernel (e.g. for mounting an authenticated UBIFS as root file system). libkeyutils usually invokes syscall() directly. As syscall() is not provided by klibc, libkeyutils has to be slightly modified for using the klibc wrappers. Signed-off-by: Christian Eggers <ceggers at arri.de> ---
