version dup3

COMPAT_NETBSD32: Add support for epoll(2).

Create compat_100 module infrastructure now that we have branched
for NetBSD-10

Compile in compat32 syscall names all the time, as we do for native
syscall names. Needed for dtrace.

branches: 1.52.4;
Add ACL support for FFS. From FreeBSD.

Add a NetBSD native futex implementation, mostly written by riastradh@.
Map the COMPAT_LINUX futex calls to the native ones.

Split out the quota code from the rest of compat_netbsd32 module. This
allows loading of compat_netbsd32 on kernels that don't have ``options
QUOTA'' enabled.

Add a new member to struct vfsstat and grow the unused members
The new member is caled f_mntfromlabel and it is the dkw_wname
of the corresponding wedge. This is now used by df -W to display
the mountpoint name as NAME=

make things compile again.

Disable netbsd32_drm.c until it receives proper review.

compat32 drm ioctl support from Surya Shankar at GSoC 2019

use option quota

remove dup

Merge the [pgoyette-compat] branch

quotactl is always included, regardless of options QUOTA.

move mmap(), compat 40 mount(), pipe() and getfh() into their own files
as the implementation is non trivial or is compat. mark old mount()
properly instead of manually #if'ing ito to ENOSYS.

move rlimit and quota code into their own modules.

(netbsd32_netbsd.c should have only simple shims. anything more
than copying arguments from one args struct to the other should
not be placed in this file. still a couple more to move out.)

Updated from the original patch in the PR by me.

branches: 1.38.2;
Missed these.

Only include the compat_14 sys calls if this being compiled as part of
the compat_netbsd32_sysvipc module.

Properly mark netbsd32_mqueue.c to depend on 'options MQUEUE'

Yes, MQUEUE is included in all kernels by default, but it can be removed.
If it is removed, the compat_netbsd32 module should not include it, either.

add netbsd32 support for nfssvc(2). we do this by defining 5 copyin/out
functions that do all the ugly work, are just plain copyin/out for the
native system calls, and do the necessary translations for netbsd32.

with this i'm able to run 32 bit nfsd and mountd on 64 bit kernel and
mount the file systems remotely.

Reviewed by christos@.

clean up a little:
- delete ktrsyscall32()
- add a check #ifdef _LP64 to do the conversion if P_32 is set to the
standard ktrsyscall()
- add a couple of similar _LP64/P_32 checks to the systrace code.

this should get systrace working for 32 bit apps as well as complete
ktrace support for "trace_enter/trace_exit" using platforms such as amd64.

XXX: systrace isn't supported on sparc64 currently... (it doesn't use
trace_enter/trace_exit, or have it's own calls to systrace_xxx()...)

add a copy of the ktrsyscall() entry point for 32 bit emulated calls.
the main purpose of this function is to adjust the "argsize" value of
the ktrace syscall record, otherwise userland will see N/2 (rounded
down) arguments instead of N.

move sparc32 to netbsd32; split out MD part (signal handling) (mostly via repository copy, rename and perl -pi :-)

Overhaul. Now will run simple things like /bin/sh and /bin/echo.

add a 32-bit compatibility module for the sparc64 port, so it can run NetBSD/sparc binaries with a LP64 kernel.

Add a new member to struct vfsstat and grow the unused members
The new member is caled f_mntfromlabel and it is the dkw_wname
of the corresponding wedge. This is now used by df -W to display
the mountpoint name as NAME=

make things compile again.

Disable netbsd32_drm.c until it receives proper review.

compat32 drm ioctl support from Surya Shankar at GSoC 2019

use option quota

remove dup

Merge the [pgoyette-compat] branch

quotactl is always included, regardless of options QUOTA.

move mmap(), compat 40 mount(), pipe() and getfh() into their own files
as the implementation is non trivial or is compat. mark old mount()
properly instead of manually #if'ing ito to ENOSYS.

move rlimit and quota code into their own modules.

(netbsd32_netbsd.c should have only simple shims. anything more
than copying arguments from one args struct to the other should
not be placed in this file. still a couple more to move out.)

PR kern/51514: ptrace(2) fails for 32-bit process on 64-bit kernel

Updated from the original patch in the PR by me.

branches: 1.38.2;
Missed these.

Only include the compat_14 sys calls if this being compiled as part of
the compat_netbsd32_sysvipc module.

Properly mark netbsd32_mqueue.c to depend on 'options MQUEUE'

Yes, MQUEUE is included in all kernels by default, but it can be removed.
If it is removed, the compat_netbsd32 module should not include it, either.

add netbsd32 support for nfssvc(2). we do this by defining 5 copyin/out
functions that do all the ugly work, are just plain copyin/out for the
native system calls, and do the necessary translations for netbsd32.

with this i'm able to run 32 bit nfsd and mountd on 64 bit kernel and
mount the file systems remotely.

Make the emulations, exec formats, coredump, NFS, and the NFS server
into modules. By and large this commit:

- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime

Add missing lwp syscalls. Put them all together into a new file,
netbsd32_lwp.c, and remove remaining traces of SA.

This still needs some MD (and possibly MI, depending on the chosen
solution) changes to actually work.

- Make better use of COMPAT_XX type in syscalls.master
- Remove useless (thanks to COMPAT_XX behaviour) #ifdefs in
syscalls.master
- Make netbsd32_compat_43.c compiled per COMPAT_LINUX32 because the latter
needs stuff from it.

Fixes Perry's PR#34951.

- Split sys_kevent into kevent1 so that it can be used by COMPAT_NETBSD32
code.

- To achieve COMPAT_NETBSD32 compatibility, introduce a parameter to
kevent1 that points to functions that do the actual copyin/copyout
operations. This is similar to what was done in FreeBSD by Paul Saab.

- Add the COMPAT_NETBSD32 definitions and hooks.
