--- Comment #17 from stefano.al...@gmail.com --- The previous patch I had posted was actually a quick fix, since, as I wrote, I didn't really find out the cause of the problem with listen. However, upon further inspection, it turned out that the problem was caused by closing all the file descriptors greater than 2 before calling socket. By adding some debug code I found out that the socket was given file descriptor 3, and calling getsockopt with SO_TYPE on this fd always returned 2, which is SOCK_DGRAM, regardless of which type of socket was required in the call to socket. I don't know the reason for this behavior, the only thing I noticed is that when execute_kwallet is called the file descriptor 3 is indeed assigned to another socket, but I've no clue on the origin of this socket. Since we don't want kwallet to inherit irrelevant file descriptors from his parent, I replaced the call to close with a call to fcntl, which sets the FD_CLOEXEC flag. This solves the problem and should prevent undesired fd inheritance as well. -- You are receiving this mail because: You are watching all bug changes.
