* linux: Add posix_spawnattr_{get, set}cgroup_np (BZ 26371)Adhemerval Zanella Netto2023-09-051-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | These functions allow to posix_spawn and posix_spawnp to use CLONE_INTO_CGROUP with clone3, allowing the child process to be created in a different cgroup version 2. These are GNU extensions that are available only for Linux, and also only for the architectures that implement clone3 wrapper (HAVE_CLONE3_WRAPPER). To create a process on a different cgroupv2, one can use the: posix_spawnattr_t attr; posix_spawnattr_init (&attr); posix_spawnattr_setflags (&attr, POSIX_SPAWN_SETCGROUP); posix_spawnattr_setcgroup_np (&attr, cgroup); posix_spawn (...) Similar to other posix_spawn flags, POSIX_SPAWN_SETCGROUP control whether the cgroup file descriptor will be used or not with clone3. There is no fallback if either clone3 does not support the flag or if the architecture does not provide the clone3 wrapper, in this case posix_spawn returns EOPNOTSUPP. Checked on x86_64-linux-gnu.

* posix: Replace posix_spawnattr_tc{get,set}pgrp_np with ↵Adhemerval Zanella2022-02-021-2/+1
| | | | | | | | | | | | | | | | | | posix_spawn_file_actions_addtcsetpgrp_np The posix_spawnattr_tcsetpgrp_np works on a file descriptor (the controlling terminal), so it would make more sense to actually fit it on the file actions API. Also, POSIX_SPAWN_TCSETPGROUP is not really required since it is implicit by the presence of tcsetpgrp file action. The posix/tst-spawn6.c is also fixed when TTY can is not present. Checked on x86_64-linux-gnu and i686-linux-gnu. Reviewed-by: Carlos O'Donell <carlos@redhat.com> Tested-by: Carlos O'Donell <carlos@redhat.com>
* posix: Add terminal control setting support for posix_spawnAdhemerval Zanella2022-01-251-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 does not specify 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.
