2017-11-09Temporarily mask sigchld to avoid race condition in forkPeter Bex
We do a fork, and immediately afterwards we insert a scsh-process object into the pending processes table with the pid of the newly created child process. However, sigchld may arrive in between the fork and the insertion of the scsh-process object into the pending process table. The sigchld handler will reap the child process and attempt to update the pending scsh-process object, but it can't find it yet because the insertion of this object into the table happens after the fork, thus losing the reaped child's exit status. Then, if the program waits for the process after that, we enter an infinite busy waiting loop that expects a sigchld to arrive and update the object through the table, but that never happens because the child has already been reaped.
