Commit Message

Adhemerval Zanella July 7, 2021, 1:32 p.m. UTC
Changes from v2:

  - Fixed build on Hurd.

Changes from v1:

  - Fixed the testcase where the terminal file descriptor is not set
    in some cases.
  - Added more check for the case where a new group should be created.
  - Use __getpgid(0) instead of getpgrp() to avoid the need to add an
    internal alias for getpgrp().

--

Currently there is no proper way to set the controlling terminal through
posix_spawn() in race free manner [1].  This forces shell implementations
to keep using fork()+exec() when launching background process groups,
even when using posix_spawn() yields better performance.

This patch adds a new GNU extension so the creating process can
configure the created process terminal group.  This is done with a new
flag, POSIX_SPAWN_TCSETPGROUP, along with two new attribute functions:
posix_spawnattr_tcsetpgrp_np(), and posix_spawnattr_tcgetpgrp_np().
The function sets a new attribute, spawn-tcgroupfd, that references to
the controlling terminal.

The controlling terminal is set after the spawn-pgroup attribute, and
uses the spawn-tcgroupfd along with current creating process group
(so it is composable with POSIX_SPAWN_SETPGROUP).

To create a process and set the controlling terminal, one can use the
following sequence:

    posix_spawnattr_t attr;
    posix_spawnattr_init (&attr);
    posix_spawnattr_setflags (&attr, POSIX_SPAWN_TCSETPGROUP);
    posix_spawnattr_tcsetpgrp_np (&attr, tcfd);

If the idea is also to create a new process groups:

    posix_spawnattr_t attr;
    posix_spawnattr_init (&attr);
    posix_spawnattr_setflags (&attr, POSIX_SPAWN_TCSETPGROUP
				     | POSIX_SPAWN_SETPGROUP);
    posix_spawnattr_tcsetpgrp_np (&attr, tcfd);
    posix_spawnattr_setpgroup (&attr, 0);

The controlling terminal file descriptor is ignored if the new flag is
not set.

This interface is slight different than the one provided by QNX [2],
which only provides the POSIX_SPAWN_TCSETPGROUP flag.  The QNX
documentation is not on how the controlling terminal is obtained nor
how it iteracts with POSIX_SPAWN_SETPGROUP.  Since a glibc
implementation is library based, it is more straightforward and avoid
requires additional file descriptor operations to request the caller
to setup the controlling terminal file descriptor (and it also allows
a bit less error handling by posix_spawn()).

Checked on x86_64-linux-gnu and i686-linux-gnu.
