This was always showing up as 0, because apparently we need to query
creation_time for the task, not a thread.
Here's a before vs after comparison:

Shifting (signed) 1 to left 31 positions is undefined behavior. So make
this an unsigned so it becomes defined behavior.

mach_port_t are mach_port_name_t and thus require %u instead of %lu.

* procfs/process.c (entries): Add PSTAT_THREAD_SCHED in `needs' field of
entry for process_file_gc_stat.
|
|
Last_processor is an int in the proc info, and there aren't
really plans for machines with more than 4 billion processors.
* procfs/process.c (process_file_gc_stat): Make last_processor unsigned
instead of long unsigned.
|
|
Read last_processor (new member) from thread_info structures, and fill stat
structure with this.
* configure.ac: Check whether thread_sched_info structure includes
`last_processor' member.
* proc/info.c (S_proc_getprocinfo)
[HAVE_STRUCT_THREAD_SCHED_INFO_LAST_PROCESSOR]: Set `last_processor' field.
* procfs/process.c (process_file_gc_stat)
[HAVE_STRUCT_THREAD_SCHED_INFO_LAST_PROCESSOR]: Set last processor proc
field to `thsi->last_processor'.
[!HAVE_STRUCT_THREAD_SCHED_INFO_LAST_PROCESSOR]: Set last processor proc
field to 0.

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.

procfs: Fix compiler warnings.
* include/sys/procfs.h: Change uintptr_t to vm_address_t.
* procfs/process.c: Fix format strings.
* procfs/rootdir.c: Add missing casts.

Fixes https://savannah.gnu.org/bugs/?32770 .
* procfs/process.c (process_file_gc_maps): New function.
(entries): Use the new function to implement /proc/N/maps.
|
|
* procfs/process.c (process_stat_make_node): Fix typo in comment.
|
|
Move the procfs translator to its own subdirectory 'procfs'.
This is the last commit to this repository. Development of the procfs
translator will continue in the main Hurd repository.
* procfs/Makefile: Replace the standalone Makefile with the one from
the Debian packaging repository.
