Use a struct hurd_port for the cached exec server port,
so it is properly reference-counted and locked.
* boot-start.c (diskfs_exec): Variable removed.
(diskfs_start_bootstrap): Make it a local here.
Install that port in _diskfs_exec_portcell.
(diskfs_S_fsys_init): Use _diskfs_exec_portcell instead
of diskfs_exec.
* init-init.c (_diskfs_exec_portcell): New variable.
(diskfs_init_diskfs): Initialize it.
* priv.h: Declare it.
* diskfs.h (diskfs_exec, diskfs_exec_ctl): Remove decls.
* file-exec.c (diskfs_S_file_exec): Use _diskfs_exec_portcell instead
of diskfs_exec.

* boot-start.c (diskfs_start_bootstrap): Twiddle boot-time messages.

|
|
* boot-start.c (_diskfs_boot_privports): Renamed from diskfs_*.
* priv.h: Declare it.

* file-statfs.c (diskfs_S_file_statfs): Initialize mount options
in statbuf.

|
|
* opts-std-startup.c (startup_options): Move -C above "Boot options:",
give it a docstring. Docstrings for --bootflags, --boot-command.
(_diskfs_boot_command): New variable.
(startup_options, parse_startup_opt): New option --boot-command,
consumes remaining args to set _diskfs_boot_command.
* priv.h: Declare _diskfs_boot_command.
* boot-start.c (diskfs_start_bootstrap): If diskfs_exec_server_task is
null, assume we are running as the boot command and have a root with
/servers/exec.
If _diskfs_boot_command is set, start that command in place of init.
If can't lookup initname, print error msg and loop to prompt.
Put a newline before "Init name" prompt.
After starting exec server, try to set active trans on /servers/exec.
(diskfs_boot_getpriv): New function: if _hurd_host_priv
is null, use fsys_getpriv on our bootstrap port.
(parent_task): New static variable, set there with fsys_getpriv call.
(diskfs_S_fsys_init): If diskfs_exec_server_task is null, don't do
anything with it; instead register parent_task as our child
and send an fsys_init to our parent on our bootstrap port.
* console.c (diskfs_console_stdio): Call diskfs_boot_privports before
get_privileged_ports if diskfs_boot_flags is set.
|
|
* file-exec.c (diskfs_S_file_exec): If exec server port is stale, try
once to look up a new one.
|
|
|
|

instead of int* for ARGZ_LEN arg.
|
|

NP->dn_set_ctime if we actually set the flags.
|
|
|

the old diskfs_root_node when switching to a virtual root.
|
|
|

warp us to that as a virtual root directory.
