* Make RPC input array parameters constSamuel Thibault2022-01-162-7/+7
| | | | | This follows mig's cf4bcc3f1435 ("Also add const qualifiers on server side")
* Fix build warningsSamuel Thibault2022-01-012-7/+7
| | | | No actual behavior change.
* proc: Fix building with old glibcSamuel Thibault2020-12-291-0/+4
| | | | * proc/wait.c (WNOWAIT): Define if not already defined.
* proc: Fix WIFCONTINUEDSamuel Thibault2020-12-281-0/+1
| | | | * proc/wait.c (S_proc_mark_cont): Set p_status to __W_CONTINUED.
* proc: support waitid(WNOWAIT)Samuel Thibault2020-12-281-3/+9
| | | | | * proc/wait.c (S_proc_waitid): When options contains WNOWAIT, do not set p_waited or complete child death.
* Add proc_waitidSamuel Thibault2020-12-272-11/+46
| | | | | | | | | | | | | | | | | | | proc_wait assumes that the caller always wants WEXITED, but waitid() does not. The new proc_waitid RPC requires the caller to specify at least one of WEXITED, WSTOPPED, or WCONTINUED. * hurd/process.defs (proc_waitid): New RPC. * hurd/process_reply.defs (proc_waitid): New RPC. * hurd/process_request.defs (proc_waitid): New RPC. * proc/proc.h (struct proc): Add p_continued field. * proc/wait.c (WCONTINUED, WEXITED): Define if not already defined. (S_proc_wait): Rename implementation to S_proc_waitid, and modify to stop assuming WEXITED. Add support for WCONTINUED. (S_proc_wait): Reimplement by just calling S_proc_waitid with an additional WEXITED. (proc_mark_stop): Clear p_continued. (proc_mark_cont): Set p_continued, clear p_waited, wake any waiting parent.
* proc: Also send SIGCHLD on child restartSamuel Thibault2020-12-271-0/+5
| | | | | * proc/wait.c (S_proc_mark_cont): When parent has not set nostopcld, send a SIGCHLD with CLD_CONTINUED.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | by adding proc_set/get_exe to the proc server, making exec call proc_set_exe, and libps call proc_get_exe. procfs can then just retrieve the information to make the "exe" symlink. * hurd/process.defs (proc_set_exe, proc_get_exe): New RPCs. * hurd/process_request.defs: Likewise. * hurd/process_reply.defs: Add skips for proc_set_exe and proc_get_exe RPCs. * proc/proc.h (struct proc): Add `exe' field. * proc/info.c (S_proc_set_exe, S_proc_get_exe): New functions. * proc/mgt.c (process_has_exited): Free p->exe.

* Pass the kernel's task port to proc.Justus Winter2017-03-121-5/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

(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.
* proc: Hierarchical proc servers.Justus Winter2017-03-115-2/+398
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, a Subhurd's tasks were shown as weird processes in the Motherhurd. This change connects the proc server in the Motherhurd with the proc server in the Subhurd, embedding the Subhurd's process hierarchy. Subhurd's processes can now be inspected and debugged like any other process. * NEWS: Update. * boot/boot.c (mach_msg_forward): New function. (boot_demuxer): Forward messages arriving on the new task notification port from the proc server, and forward them to the proc server inside the Subhurd via the notification port. * proc/info.c (S_proc_task2proc): Relay request for processes in a task namespace to the Subhurd's proc server. (S_proc_pid2proc): Likewise. (S_proc_getprocargs): Likewise. (S_proc_getprocenv): Likewise. (S_proc_getprocinfo): Likewise. Translate PIDs. (S_proc_getloginid): Likewise.

* hurd: Use polymorphic port types to return some rights.Justus Winter2017-03-102-4/+10
| | | | | | | | | | | | | | | | | | | | | Currently, the RPC definitions of two procedures of the process subsystem assume that the rights are created from a receive right. Similarly, 'proc_getmsgport' assumes that the right is to be copied. This needlessly limits the ability to relay the RPC in server code. This fixes this. The protocol is unchanged, only the generated server stubs assume an additional parameter for the type. * hurd/process.defs (proc_getmsgport): Make 'msgport' parameter polymorphic. (proc_task2proc): Make 'proc' parameter polymorphic. (proc_pid2proc): Likewise. * hurd/process_reply.defs (proc_getmsgport): Likewise. (proc_task2proc_reply): Likewise. (proc_pid2proc_reply): Likewise. * proc/info.c (S_proc_task2proc): Adapt server function. (S_proc_pid2proc): Likewise. * proc/msg.c (S_proc_getmsgport): Likewise.

| | | | | | * proc/mgt.c (namespace_find_root): New function. (process_has_exited): Use new function. * proc/proc.h (namespace_find_root): New declaration.
* proc: Remove erroneous process entry.Justus Winter2017-03-091-0/+31
| | | | | | | | | | | | | Previously, there was a spurious copy of PID 1 in the process table, usually PID 8. PID 1, usually a sysvinit compatible process, needs to be PID 1 even though it is not actually the first process on the Hurd. To this end, PID 1 is reserved, and the task is later supplied to proc via proc_set_init_task once startup starts sysvinit. Fixes 8d16db0cc28b2d911aee918d5c3582ad29ddfeed. * proc/mgt.c (S_proc_set_init_task): Check if sysvinit's task already made it into the process table, and remove it if so.
* proc: Receive new-task notifications on kernel's process port.Justus Winter2017-03-093-2/+14
| | | | | | | * proc/main.c (main): Initialize 'kernel_proc' and use it to register for new-task notifications. * proc/mgt.c (S_mach_notify_new_task): Adapt receiver check. * proc/proc.h (kernel_proc): New variable.
* proc: Open console earlier.Justus Winter2017-03-061-11/+28
| | | | | | | | This way, we can print diagnostics earlier. * proc/main.c (open_console): New function. (main): Call the new function as soon as we have the master device port.
* Adjust to the fixed new task notifications.Justus Winter2016-11-011-2/+2
| | | | | | * boot/boot.c (S_mach_notify_new_task): The send rights are now indeed moved to the target task, adjust accordingly. * proc/mgt.c (S_mach_notify_new_task): Likewise.
* proc: Fix new task notifications.Justus Winter2016-11-012-5/+16
| | | | | | * proc/mgt.c (S_mach_notify_new_task): Fix receiver handling, fix port leak. * proc/mig-mutate.h: Mutate the task notification protocol.
* Avoid warnings if increasing a threads priority fails.Justus Winter2016-10-151-1/+6
| | | | | | | * libports/manage-multithread.c (adjust_priorities): Avoid displaying error messages if we do not have the privileged processor set port by treating this error condition like EPERM. * proc/main.c (increase_priority, main): Likewise.
* proc: Fix permission check.Justus Winter2016-08-081-1/+1
| | | | | * proc/mgt.c (S_proc_mark_important): Fix checking whether the receiver is a child of startup.
* proc: Fix references to the startup server.Justus Winter2016-08-074-11/+10
| | | | | | | | * proc/main.c: Fix references to the startup server in code and comments. * proc/mgt.c: Likewise. * proc/msg.c: Likewise. * proc/proc.h: Likewise.
* Make sure to complete auth_server_authenticateSamuel Thibault2016-02-141-7/+9
| | | | | | * boot/boot.c (S_io_reauthenticate): Keep calling auth_server_authenticate while it returns EINTR. * proc/mgt.c (S_proc_reauthenticate): Likewise.
* Drop OTHERLIBS and use LDLIBS exclusivelyFlavio Cruz2015-12-311-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When cross-compiling, OTHERLIBS magically turns -lpthread into the path to the host libpthread.so file, resulting in build issues. LDLIBS does not suffer from this problem and it seems that is already being used in other Makefiles. This patch removes OTHERLIBS entirely from the build system. * Makeconf: Remove references to OTHERLIBS * auth/Makefile: Replace OTHERLIBS with LDLIBS. * boot/Makefile: Likewise. * console/Makefile: Likewise. * exec/Makefile: Likewise. * ext2fs/Makefile: Likewise. * fatfs/Makefile: Likewise. * ftpfs/Makefile: Likewise. * hostmux/Makefile: Likewise. * isofs/Makefile: Likewise. * libhurd-slab/Makefile: Likewise. * nfs/Makefile: Likewise. * nfsd/Makefile: Likewise. * pfinet/Makefile: Likewise. * proc/Makefile: Likewise. * procfs/Makefile: Likewise. * random/Makefile: Likewise. * storeio/Makefile: Likewise. * term/Makefile: Likewise. * tmpfs/Makefile: Likewise. * usermux/Makefile: Likewise.

* proc: call `startup_essential_task' earlierJustus Winter2015-01-173-1/+26
| | | | | | | | | | | | | | | | | | | | | 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'.

Terminate all tasks if the root process dies. Reap dead tasks. (S_mach_notify_new_task): For newly created tasks thats parent is in a namespace, call S_proc_child and forward the `mach_notify_new_task' message. (S_proc_make_task_namespace): New function.

(create_startup_proc): Rename to create_init_proc. * proc/main.c (main): Create placeholder proc object for pid 1. * proc/mgt.c: Use init_proc instead of startup_proc, as the former is the new root of the process tree. (create_startup_proc): Rename to create_init_proc. (S_proc_set_init_task): New function. * doc/hurd.texi (Server Bootstrap): Update accordingly. * procfs/main.c: Do not hard-code kernel pid, use pids.h instead.

* proc: include the mig-generated server headers in main.cJustus Winter2014-01-201-5/+5
| | | | | | | | | GNU MIG recently gained support for emitting x_server_routine declarations in the generated server header file. Using this declaration, the x_server_routine functions can be inlined into the demuxer function. * proc/main.c: Include the mig-generated server headers.
* proc: improve the message_demuxer functionJustus Winter2013-12-021-12/+18
| | | | | | | | | | Handle multiple request types as recommended by the Mach Server Writer's Guide section 4, subsection "Handling Multiple Request Types". This avoids initializing the reply message in every X_server function. The reply message has already been properly initialized in libports, so there is no need to call mig_reply_setup. * proc/main.c (message_demuxer): Improve the demuxer function.
