[systemd-devel] systemctl runs systemd-tty-ask-password-agent and hangs?

[Albert Strasheim]

Hello again

I had the same problem again today trying to start a service.

The last few system calls made by systemd-tty-ask-password-agent are:

19048 mkdir("/run", 0755)               = -1 EEXIST (File exists)
19048 mkdir("/run/systemd", 0755)       = -1 EEXIST (File exists)
19048 mkdir("/run/systemd/ask-password", 0755) = -1 EEXIST (File exists)
19048 inotify_init1(O_CLOEXEC)          = 4
19048 inotify_add_watch(4, "/run/systemd/ask-password",
IN_CLOSE_WRITE|IN_MOVED_TO) = 1
19048 rt_sigprocmask(SIG_SETMASK, [INT TERM], NULL, 8) = 0
19048 signalfd4(-1, [INT TERM], 8, O_NONBLOCK|O_CLOEXEC) = 5
19048 open("/run/systemd/ask-password",
O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC) = 6
19048 getdents(6, {{d_ino=9748, d_off=1, d_reclen=24, d_name="."}
{d_ino=9747, d_off=2, d_reclen=24, d_name=".."}}, 32768) = 48
19048 getdents(6, {}, 32768)            = 0
19048 close(6)                          = 0
19048 poll([{fd=4, events=POLLIN}, {fd=5, events=POLLIN}], 2, -1) = 1
([{fd=5, revents=POLLIN}])

I am running systemd-24-1.fc15.x86_64.

Full trace attached.

Regards

Albert
