PR/55102: Kamil Rytarowski: Duplicate fifo_vnodeop_entries,
fifo_vnodeop_opv_desc symbols.

Many filesystems ffs, lfs, ulfs, chfs, ext2fs etc. use fifofs
internally for their fifo vnops. NFS does too, but it also needs
networking anyway. Unfortunately fifofs brings in a lot of the
networking code so that the rumpkernel is not well partition. In
addition the fifo code is rarely used.

The existing hack depended on duplicating the above symbols and
adding minimal functionality for the majority of the the tests
(except the ffs and the puffs one). In these two cases both symbols
were loaded and the symbol sizes clashed which broke the sanitizers.
While this can be fixed with weak symbols and other kinds of
indirection, it is more straight forward to select between the
minimal and the full fifofs implementation by introducing a new
shared library librumpvfs_nofifofs.

New extended attributes test (does not work until we commit kernel changes)

Centralize the base rump libraries into a variable used by all the other
Makefiles so that we can make changes to it centrally as needed and have
less mess. Fixes the sun2 build that needs rumpvfs after librump after
the latest changes.

add tests for the mount update from rw to rw+log, which used to case the panic
reported in PR kern/52056

Move sysproxy support into a separate component, rumpkern_sysproxy,
instead of it being always provided by the rump kernel base. This
move accomplishes two things:

1) it is no longer necessary to provide sysproxy hypercall stubs for
platforms which do not want to use sysproxy
2) it is easier to reason about the security aspects, since configurations
not linking the sysproxy component simply do not support remote
system calls

discussed on rumpkernel-users

Make parts of the quota tests useable for more than quotas:
- rename h_quota2_server to h_ffs_server, there's nothing about quotas
in there.
- extract non-quota parts of quotas_common.sh to ffs_common.sh

branches: 1.16.4;
Don't descend into non-existing subdirectory "clients".

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

for details.

test snapshots on ffsv2 too

test fss with underlying fs mounted with MNT_LOG

Reorder the library specifications, so that we don't depend on the
library dependencies recorded in shared libraries, allowing these
to be linked statically as well.

Need to use the ${PRINTOBJDIR} trick for LIBISPRIVATE ...

Include h_fsmacros instead of ffs.c and link in test lib.

Convert "The Original" rename race test from to vfs and retire the
ffs/tmpfs versions. The only difference is that the origamical
one mounted ffs with MNT_LOG (and therein actually lay the bug).

Small xfail testcase to exercise 48k ffs image mount, from problem
reported by Hubert Feyrer on netbsd-users@.

test for the very basic snapshot features

regression test for fifos on ffs

XXX: same test apart for mount/unmount could be used on other
fifo-supporting file systems (r/w support required, though).

filesystems now use getdisksize() which is in librumpdev_disk.

branches: 1.4.2;
Merge librumpfs_ufs into librumpfs_ffs. This reflects what happened
with the ffs kernel module and follows the trend of retiring ufs.
It also allows to get rid of a special case kludge in runtime module
loading, since ufs was not really a module. librumpfs_ufs is now
obsoleted and ffs consumers should be linked solely against
librumpfs_ffs.

Use rump_sys_mount() instead of ukfs_mount(). Just a few more
steps and we can have a switch for if we want to run tests against
a rump kernel or a real kernel.
