1 - ptrace(2) syscall for native emulation
2 - common ptrace(2) syscall code (shared with compat_netbsd32)
3 - support routines that are shared with PROCFS and/or KTRACE
* Add module glue for #1 and #2. Both modules will be built-in to the
kernel if "options PTRACE" is included in the config file (this is
the default, defined in sys/conf/std).
* Mark the ptrace(2) syscall as modular in syscalls.master (generated
files will be committed shortly).
* Conditionalize all remaining portions of PTRACE code on a new kernel
option PTRACE_HOOKS.
XXX Instead of PROCFS depending on 'options PTRACE', we should probably
just add a procfs attribute to the sys/kern/sys_process.c file's
entry in files.kern, and add PROCFS to the "#if defineds" for
process_domem(). It's really confusing to have two different ways
of requiring this file.
rather than including in kernels with KDTRACE_HOOKS defined. Update
the dtrace_fbt module to depend on the zlib module.
Bump kernel version to avoid module mismatch.
Welcome to 7.99.38 !
Discussed on tech-kern:
https://mail-index.netbsd.org/tech-kern/2016/01/24/msg020069.html
API is still experimental and likely to change. (Obvious changes:
either remove extra arguments everywhere, or shrink psref_target to a
single bit, at the expense of possibly valuable diagnostic checks.)
Should do some real testing before we use this in anger!
For monolithic kernels, both modules will be compiled as "built-ins",
while modular environments will be able to load the SYSVSEM, SYSVSHM,
and SYSVMSG code independant from the rest of compat.
This is a necessary precursor step to making the "STD" SYSV* code
into a separate module.
Tested in both monolithic and modular environments with no errors
seen.
- move the syncer into kern/vfs_subr.c.
- change the syncer to process the mountlist and VFS_SYNC as appropriate.
- use an API for mount points similiar to the API for vnodes:
- vfs_syncer_add_to_worklist(struct mount *mp) to add
- vfs_syncer_remove_from_worklist(struct mount *mp) to remove a mount.
No objections on tech-kern@
Merge common disk driver functionality in ld.c with dksubr.c.
Adjust the two previous users of dk_intf (cgd and xbd) to
the changes.
