* Modernize code by removing use of old style definitions.Flavio Cruz2023-04-031-1/+1
| | | | | Also add -Werror=old-style-definition to enforce new code. Message-Id: <ZBZ+8xf7GHy2RT/h@jupiter.tail36e24.ts.net>
* proc: Do not reference a task port when allocation failedSamuel Thibault2022-12-241-1/+2
|
* S_mach_notify_new_task: Ignore notification of dead tasksSamuel Thibault2022-12-211-0/+3
| | | | | | | In case the new task notification gets late, the task may have terminated already, and thus a dead name gets provided in the notification. We should just ignore this, otherwise the task hashing would get collisions on all such dead tasks ports.
* proc: Do not deallocate input ports on errorSamuel Thibault2022-12-211-11/+4
| | | | | The error handling code would already deallocate them, thus leading to duplicate deallocation, spurious destroy, and later on port mixup.
* proc: Add task to hashes before requesting death notifySamuel Thibault2022-12-211-5/+4
| | | | | In case the task dies very early and thus the notification arrives very early.
* Rename proc_complete_reauthentication to proc_reauthenticate_completeSamuel Thibault2022-08-101-7/+7
| | | | For coherency with the existing RPCs
* Make proc_reauthenticate () recreate proc portSergey Bugaev2022-08-101-29/+107
| | | | And add proc_complete_reauthentication ()
* Remove the concept of process ownerSergey Bugaev2022-08-101-23/+4
| | | | | | | | | | Now that it's completely unused. procinfo.owner is now simply set to the first UID that a process has. proc_setowner () is kept for compatibility, but now does nothing. The clients still try to call it, though, for compatibility with older proc server versions.
* proc: Add proc_reauthenticate_reassign ()Sergey Bugaev2022-08-101-0/+137
| | | | | This is a new RPC to atomically change the UIDs of a process, recreate its process port, and reassign a different task to it.
* proc: Fix an error pathSergey Bugaev2022-08-101-4/+9
| | | | | If the allocation failed, we want to leave the p_ids pointer as it was, and properly propagate the error code.
* proc: Track both available and effective uidsSergey Bugaev2022-08-101-10/+11
| | | | | This is in preparation for using the UID's to evaluate permissions in a different way.
* proc: Use ports_request_dead_name_notification ()Sergey Bugaev2022-08-101-9/+1
|
* proc: Drop some mach_port_destroy () usesSergey Bugaev2022-08-101-11/+5
| | | | | | | | | | | | | | | | mach_port_destroy () is a dangerous API that has to be used with extreme care. Namely, it destroys not one user reference, but *all* user references that a task has for a port name. Different parts of a program may all keep separate references on a port without coordinating it with each other (which is the whole idea behind reference counting). If one part of a program decides to destroy a port with mach_port_destroy () without informing others, others may still believe they hold a reference and will continue to use the name as if it still refered to the now-destroyed port right. This consitutes a port use-after-free, even if their use is also deallocating their reference. In the particular case of the proc server, this manifested itself as S_proc_reassign () destroying all user references to the task port right before the task port right is deallocated again in the dead-name notification handler.
* Implement /proc/<pid>/exeSamuel Thibault2018-01-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | Our variants print stack traces on failures. This will make locating errors much easier.
* proc: Hierarchical proc servers.Justus Winter2017-03-111-0/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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.

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.

* proc: store the privileged host port in _hurd_host_privJustus Winter2013-11-281-1/+1
| | | | | | | | | | | | | | | | | Store the privileged host port in _hurd_host_priv like it is done in the root filesystem. This fixes the thread priority adjustment in the proc server.

* proc: do not hand out PID 0Justus Winter2013-09-211-1/+1
| | | | | | Using PID 0 causes various problems. This makes genpid skip PID 0. * proc/mgt.c (genpid): Start PIDs at 1.

* proc: add proc_mark_important server codeJustus Winter2013-08-291-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | This is based on a fragment of Guillem Jovers patch presented here: http://lists.gnu.org/archive/html/bug-hurd/2006-02/msg00081.html It has been refreshed, updated and the copyright year is adjusted properly. It has been complemented with the necessary features to address the issues the original patch set out to address, namely that killall5 freezes the proc translator before it tries to walk over /proc/*/stat to decide which process to kill. Prior to this patch (and the one marking the procfs server as important process), killall5 would deadlock trying to walk over the proc file system. Ironically it would not have killed any process later on even if it had the chance, since two values obtained from /proc/*/stat are currently hardcoded to zero in our procfs. Patches addressing the problem as a whole are prepared and will be sent as a follow up. * proc/proc.h (struct proc): Add p_important field. * proc/pgrp.c (S_proc_getpgrppids): Exclude important system processes. (S_proc_mark_important): New function. * proc/mgt.c (create_startup_proc): Mark init as important.

* Fix spurious port deallocationSamuel Thibault2011-08-111-1/+1
| | | | | | * proc/mgt.c (S_proc_exception_raise): On proc_exception_raise forwarding error, return MIG_NO_REPLY instead of 0, since the reply port may have been consumed, and the task is being terminated anyway.
* 2003-08-17 Marcus Brinkmann <marcus@gnu.org>Marcus Brinkmann2003-08-161-3/+3
| | | | * mgt.c (S_proc_dostop): Revert last change.
* 2003-06-16 Ognyan Kulev <ogi@fmi.uni-sofia.bg>Marcus Brinkmann2003-08-091-3/+6
| | | | | * mgt.c (S_proc_dostop): Instead of suspending all threads except CONTTHREAD, first suspend all threads, and then resume CONTTHREAD.
* 2002-05-07 Roland McGrath <roland@frob.com>Roland McGrath2002-05-081-9/+9
| | | | | | | | * mgt.c (S_proc_reauthenticate, S_proc_getallpids): Likewise. (add_tasks, S_proc_dostop): Likewise. (S_proc_exception_raise): int -> integer_t * pgrp.c (S_proc_getsessionpids, S_proc_getsessionpgids): Likewise. (S_proc_getpgrppids): Likewise.
* 2001-08-14 Marcus Brinkmann <marcus@gnu.org>Marcus Brinkmann2001-08-141-1/+4
| | | | | * mgt.c (S_proc_dostop): If task_threads fails, resume the suspended task.
* 2001-08-06 Roland McGrath <roland@frob.com>Roland McGrath2001-08-061-1/+1
| | | | | * mgt.c (allocate_proc): Don't zero P->p_pi. Reported by Neal H Walfield <neal@cs.uml.edu>.
* 2001-08-04 Roland McGrath <roland@frob.com>Roland McGrath2001-08-041-0/+3
| | | | * mgt.c (process_has_exited): Call ports_interrupt_rpcs last thing.
* 2001-08-04 Roland McGrath <roland@frob.com>Roland McGrath2001-08-041-20/+18
| | | | | | | | | * mgt.c (S_proc_reauthenticate): Release global_lock while making RPC. Don't mach_port_deallocate an argument port when returning an error, because mig does it for us. 2001-08-03 Roland McGrath <roland@frob.com> * mgt.c (allocate_proc): Use memset instead of lots of 0 initializers.
* 2001-08-01 Roland McGrath <roland@frob.com>Roland McGrath2001-08-021-22/+8
| | | | * mgt.c (genpid): Rewritten.
* 2001-08-02 Marcus Brinkmann <marcus@gnu.org>Marcus Brinkmann2001-08-021-0/+6
| | | | | * mgt.c (genpid): Before checking if NEXTPID is free, check if it is greater than WRAP, and if yes, start over.
