2024-12-30startup: Do not emit ARGP_ERR_UNKNOWNSamuel Thibault
This is making startup completely ignore parameters when root= is passed first on the kernel command line.
2024-08-29startup, settrans: Add missing flush of stderr to get output on waitingSamuel Thibault
2024-08-25Fix line-buffered stderrSamuel Thibault
mach_open_devstream creates a fully-buffered stream by default. This prevents from seeing various messages.
2024-08-25Make sure to also print early-fatal errors on mach consoleSamuel Thibault
In case the user is using a debug kernel, they will get to see these.

mach_port_t are mach_port_name_t and thus require %u instead of %lu. Message-Id: <Y42RELMbulK4xaKM@reue>
2022-12-03startup: Make essential tasks essential to machSamuel Thibault
Whenever a Hurd essential task crashes, startup just reboots the system since there's not much that can be done at that point. When we have a kernel debugger, however, we could at least get crashing information, so let's make Hurd's startup tell the kernel which tasks are essential, so it can trigger the debugger whenever they crash.
2022-08-10startup: Request notifications to a separate portSergey Bugaev
Since this port is never given out to anyone but the kernel, our clients can't spoof a dead-name notification this way.
2022-02-12Fix warningSamuel Thibault
* startup/startup.c (S_io_restrict_auth): Cast const uid_t * pointer to uid_t * when using it in struct idvec which always uses a uid_t* even when reading it.

This follows mig's cf4bcc3f1435 ("Also add const qualifiers on server side")
2022-01-01Fix build warningsSamuel Thibault
No actual behavior change.

2021-07-11Fix /proc/?/exe values for bootstrap processesDamien Zammit
This makes libmachdev follow the exec case, and make sure to be waiting for all bootstrap processes by waiting for the FS process. Message-Id: <20210711012042.77920-1-damien@zamaudio.com>

* startup/startup.c: Give the privileged ports to the glibc so that other code can get them.
2017-08-05Use our own variant of 'assert' and 'assert_perror'.Justus Winter
Our variants print stack traces on failures. This will make locating errors much easier.
2017-03-12Pass the kernel's task port to proc.Justus Winter
Previously, the early server bootstrap relied upon a specific task layout to determine the kernels task port. Explicitly pass it from the kernel instead. * boot/boot.c (default_boot_script): Add '--kernel-task' parameter to ext2fs. (main): New bootscript variable 'kernel-task'. * libdiskfs/boot-start.c (diskfs_kernel_task): Declaration variable. (diskfs_start_bootstrap): If '--kernel-task' was given to us, pass it along to startup. * libdiskfs/opts-std-startup.c (diskfs_kernel_task): New variable. (startup_options): Add '--kernel-task' option. (parse_startup_opt): Handle option. * proc/main.c (kernel_task): New variable. (OPT_KERNEL_TASK): New macro. (options): New variable. (parse_opt): New function. (main): Parse options. Use 'kernel_task' if provided. * release/servers.boot: Add '--kernel-task' parameter to ext2fs. * startup/startup.c (OPT_KERNEL_TASK): New macro. (options): Add '--kernel-task' option. (kernel_task): New variable. (insert_ports_fnc_t): New declaration. (run): Add argument for a function that inserts rights into the newly created task and adds arguments to the argument vector. (argz_task_insert_right): New function. (proc_insert_ports): Likewise. (parse_opt): New function. (main): Pass the kernel's task port to proc. (frob_kernel_process): Use the kernel's task port.
2017-03-12startup: Simplify reference handling.Justus Winter
* startup/startup.c (launch_core_servers): Instead of copying a send right and then deallocating it, move it. (init_stdarrays): Likewise.
2017-01-09startup: insert the kernel name in its commande lineRichard Braun
This cosmetic change sets argv[0] to "gnumach", making it easier to identify the kernel process. * startup/startup.c (frob_kernel_process): Insert "gnumach" at the start of the kernel command line arguments.
2016-11-01startup: Dump processes if we cannot find the kernel.Justus Winter
* startup/startup.c (dump_processes): New function. (frob_kerne_process): Use the new function.
2016-09-01Fix looping over runsystem possibilitiesSamuel Thibault
* startup/startup.c (launch_something): Always increment TRY even on success, so that if runsystem unexpectedly returns, we get to try a shell instead.
2016-09-01startup: Fix looping over runsystemSamuel Thibault
Thanks Brent W. Baccala for the report. * starpu/startup.c (launch_something): Always increment TRY while looping over runsystem possibilities.
2016-08-08startup: Make the kernel a child of startup.Justus Winter
* startup/startup.c (frob_kernel_process): Make the kernel a child of startup, improve error reporting.
2016-05-09startup: fix blunderJustus Winter
Fixes b04364bc. Thanks to Esa Peuha for spotting this. * startup/startup.c (run): Fix blunder.
2016-04-28startup: write all messages to stderrJustus Winter
This avoids the need to flush the buffer and works around a weird problem with 'puts' not printing a newline. * startup/startup.c: Write all messages to stderr.
2016-04-28startup: use the generated default server implementationsJustus Winter
* startup/Makefile: Set appropriate flags. * startup/startup.c: Drop most stub functions.
2016-04-28startup: add verbose parameterJustus Winter
* startup/startup.c: Add verbose parameter and inform about progress through the bootstrap procedure if it is given.
2016-04-28startup: implement bits of the fs and io protocolsJustus Winter
* startup/Makefile: Build fs and io server with default implementations. (mung_msg_S.h): Tune regexp only to match the include guard. * startup/startup.c (mig_reply_setup): New function. (demuxer): Add new protocols. Nicer implementation. (S_file_check_access): New function. (S_io_restrict_auth): Likewise.
2015-12-29fix compiler warnings in hurd/startupFlavio Cruz
startup: Fix compiler warning. * startup/startup.c (do_mach_notify_dead_name): Fix format string.
2015-07-14exec: fix setting the name of early serversJustus Winter
Previously, the exec server did not set the name of the servers started before the proc server. Instead this was done by the startup server, but this was merely a workaround, missing notably the startup server itself. * exec/exec.c (set_name): New function. (do_exec): Move the code setting the name to a new function, and also call it if the proc server is not started yet. * startup/startup.c (run): Drop hack.
2015-02-08startup: add more error handlingJustus Winter
* startup/startup.c (launch_core_servers): Add more error handling.
2015-01-17proc: call `startup_essential_task' earlierJustus Winter
Previously, the proc server did not call `startup_essential_task' until it got the message port of the startup server using `proc_setmsgport'. Now that we have `/servers/startup', we can do this in main, before we start our message service loop. A complication arises because the traditional startup server is single-threaded. Handle this by tweaking startup not to bind itself to `/servers/startup' before it is ready. * proc/main.c (main): Try to lookup `/servers/startup' and send the message here, or... * proc/msg.c (S_proc_setmsgport): ... fall back to the old way here. * proc/proc.h (startup_fallback): New variable. * startup/startup.c (main): Move code installing ourself on `/servers/startup' (install_as_translator): ... here. (launch_core_servers): And use it here, just before we reply to `/hurd/auth'.
2015-01-17startup: give the tasks we create a nameJustus Winter
* startup/startup.c (run): Name the tasks we start.
2014-12-10Replace `bzero' with `memset'Justus Winter

2014-11-21startup: bind the startup server to /servers/startupJustus Winter
Previously, the Hurd (ab)used the fact that the startup server speaks all protocols on its message port. Any server that wished to register for shutdown notifications would use proc_getmsgport to get a port to the startup server. This hardcodes the PID of /hurd/startup, and does not allow one to point a server to ones own startup server (e.g. using remap). Bind the startup server to /servers/startup instead. Use this to contact the startup server. * exec/main.c (S_exec_init): Use /servers/startup. Fall back to the old method so that the system still boots when the node /servers/startup is missing. * hurd/paths.h (_SERVERS_STARTUP): New macro. * libdiskfs/boot-start.c (diskfs_S_fsys_init): Use /servers/startup. * libdiskfs/init-startup.c (_diskfs_init_completed): Likewise. * pfinet/main.c (arrange_shutdown_notification): Likewise. * startup/Makefile (OBJS): Add fsysServer.o. * startup/startup.c (demuxer): Handle the fsys protocol.
