* 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. (S_proc_child): Duplicate parent `exe' into child's `exe'. * exec/exec.c (do_exec): Call proc_set_exe when a filename is available. * libps/ps.h (struct proc_stat): Add `exe_vm_alloced', `exe', and `exe_len' field. (PSTAT_EXE): New macro. (PSTAT_USER_BASE): Change value to make room. (proc_stat_exe, proc_stat_exe_len): New macros. * libps/procstat.c (proc_stat_set_flags): Handle PSTAT_EXE case by calling proc_get_exe. * libps/spec.c (ps_get_exe): New function. (ps_exe_getter): New structure. (ps_fmt_spec): Add "Exe" specification. * procfs/process.c (process_file_symlink_make_node, process_file_gc_exe): New functions. (procfs_dir_entry): Add "exe" entry. * startup/startup.c (launch_core_servers): Set exe paths for startup, auth, proc, and fs servers. (frob_kernel_process): Set exe path for kernel task. (S_startup_essential_task): Set exe path for exec server.
* Record executable entry for PIE core dumpsSamuel Thibault2017-12-111-0/+18
| | | | | | | | | | | | * hurd/process.defs (proc_set_entry, proc_get_entry): New RPCs. * hurd/process_reply.defs: Add skips for proc_set_entry, proc_get_entry. * hurd/process_request.defs: Likewise. * exec/exec.c (do_exec): Call proc_set_entry. * proc/proc.h (proc): Add p_entry field. * proc/mgt.c (S_proc_set_entry, S_proc_get_entry): New RPC implementations. * exec/elfcore.c (dump_core): Add at_entry note, call proc_get_entry to get it, and write it with WRITE_NOTE.
* Use our own variant of 'assert' and 'assert_perror'.Justus Winter2017-08-051-10/+10
| | | | | 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. (S_proc_pid2proc): Likewise. (S_proc_getprocargs): Likewise. (S_proc_getprocenv): Likewise. (S_proc_getprocinfo): Likewise. Translate PIDs. (S_proc_getloginid): Likewise. (S_proc_getloginpids): Likewise. * proc/mgt.c (namespace_is_subprocess): New function. (namespace_translate_pids): Likewise. * proc/msg.c (S_proc_getmsgport): Relay request for processes in a task namespace to the Subhurd's proc server. * proc/pgrp.c (S_proc_getsid): Likewise. Translate PIDs. (S_proc_getsessionpids): Likewise. (S_proc_getsessionpgids): Likewise. (S_proc_getpgrppids): Likewise. * proc/proc.h (namespace_is_subprocess): New prototype. (namespace_translate_pids): 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 Winter2017-03-091-1/+3

| | | | | | | | | | | | | | * proc/proc.h (struct proc): Add field `p_task_namespace'. * proc/mgt.c (S_proc_child): Propagate `p_task_namespace' to child. (allocate_proc): Initialize `p_task_namespace'. (namespace_terminate): New function. (process_has_exited): Reparent children of dead tasks in the namespace to the root process. 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.

| | | | | | | following 7cb7fa6b3a0d02985b4a51f7823bc1cb631d6bfa * proc/mgt.c (S_proc_exception_raise): Do not dereference e on returning EINVAL, the translation functions does it for us.

| | | | | | * proc/mgt.c (S_proc_exception_raise): Update accordingly. * proc/mig-decls.h: New file. * proc/proc_exc.defs: Add translation functions.
* 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: fix error handling in S_proc_exception_raiseJustus Winter2013-11-091-0/+2
| | | | | | Found using the Clang Static Analyzer. * proc/mgt.c (S_proc_exception_raise): Fix error propagation.
* 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: keep track of {start,end}_codeJustus Winter2013-09-151-0/+39
| | | | | | | | Any executable segments loaded from the ELF binary are in this range. * proc/proc.h (struct proc): Add {start,end}_code. * proc/mgt.h (S_proc_set_code): New function. * proc/mgt.h (S_proc_get_code): New function.
* 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.
