[Libguestfs] [libnbd PATCH v3 00/19] pass LISTEN_FDNAMES with systemd socket activation

V3 was here: <http://mid.mail-archive.com/20230215141158.2426855-1-lersek@redhat.com>;. See the Notes section on each patch for the v4 updates. The series is nearly ready for merging: every patch has at least one R-b tag, except "socket activation: avoid manipulating the sign bit". The series builds, and passes "make check" and "make check-valgrind", at every stage. Thanks for reviewing! Laszlo Laszlo Ersek (17): socket activation: fix error message upon asprintf() failure socket activation: clean up responsibilities of prep.sock.act.env.() socket activation: avoid manipulating the sign bit socket activation: check syscalls for errors in the child process socket activation: centralize resource release socket activation: plug AF_UNIX socket address (filesystem) leak on error socket activation: replace execvp() call with fork-safe variant CONNECT_COMMAND.START: fix small comment thinko about socket pair usage CONNECT_COMMAND.START: set the NBD error when fcntl() fails CONNECT_COMMAND.START: use symbolic constants for fd#0 and fd#1 CONNECT_COMMAND.START: sanitize close() calls in the child process CONNECT_COMMAND.START: check syscalls for errors in the child process CONNECT_COMMAND.START: centralize resource release CONNECT_COMMAND.START: plug child process leak on error CONNECT_COMMAND.START: replace execvp() call with fork-safe variant socket activation: generalize environment construction socket activation: set LISTEN_FDNAMES Richard W.M.
