Introduce RUMPs - Runnable Userspace Meta-Programs

/sys/rump contains programs which run unmodified kernel code in an
emulated userspace environment. The kernel environment is provided
by librump. Currently supported are a number of file systems,
which by using puffs integrate seamlessly into the system and
provide a similar user experience to if the code was running as
part of the kernel. Potential future rumpification targets include
for example parts of the networking stack and some device drivers.

This work was supported by Google Summer of Code 2007.

Rename Makefile.rump${x} to Makefile.rump${x}comp for consistency.

Support fifofs in rump. Do not include it in rumpvfs directly,
since it involves some very non-fs'y components like sockets and
local domain networking. Also (for better or worse?), call it
rump*v*fs_fifofs instead of rumpfs_fifofs, since it does not really
provide a file system driver.

Import read-only part of the NiLFS (v2) implementation for NetBSD. It has been
tested with a DEBUG+DIAGNOSTIC+LOCKDEBUG kernel. To summerise NiLFS, i'll
repeat my posting to tech-kern here:

NiLFS stands for New implementation of Logging File System; LFS done
right they claim :) It is at version 2 now and is being developed by NTT, the
Japanese telecom company and recently put into the linux source tree. See
http://www.nilfs.org. The on-disc format is not completely frozen and i expect
at least one minor revision to come in time.

The benefits of NiLFS are build-in fine-grained checkpointing, persistent
snapshots, multiple mounts and very large file and media support. Every
checkpoint can be transformed into a snapshot and v.v. It is said to perform
very well on flash media since it is not overwriting pieces apart from a
incidental update of the superblock, but that might change. It is accompanied
by a cleaner to clean up the segments and recover lost space.

My work is not a port of the linux code; its a new implementation. Porting the
code would be more work since its very linux oriented and never written to be
ported outside linux. The goal is to be fully interchangable. The code is non
intrusive to other parts of the kernel. It is also very light-weight.

The current state of the code is read-only access to both clean and dirty
NiLFS partitions. On mounting a dirty partition it rolls forward the log to
the last checkpoint. Full read-write support is however planned!

Just as the linux code, mount_nilfs allows for the `head' to be mounted
read/write and allows multiple read-only snapshots/checkpoint mounts next to
it.

By allowing the RW mount at a different snapshot for read-write it should be
possible eventually to revert back to a previous state; i.e. try to upgrade a
system and being able to revert to the exact state prior to the upgrade.

Compared to other FS's its pretty light-weight, suitable for embedded use and
on flash media. The read-only code is currently 17kb object code on
NetBSD/i386. I doubt the read-write code will surpass the 50 or 60. Compared
this to FFS being 156kb, UDF being 84 kb and NFS being 130kb. Run-time memory
usage is most likely not very different from other uses though maybe a bit
higher than FFS.

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.

Add the ability to run puffs in userspace. This means that puffs
can now be developed in userspace using puffs for development
(I hate emulators, they are annoyingly clumsy).

To e.g. mount psshfs using puffs-on-puffs, run fs/bin/syspuffs/syspuffs
with the regular mount_psshfs command line as an argument:

golem> ./syspuffs /usr/sbin/mount_psshfs ftp.netbsd.org:/pub /puffs

This will make the mount appear as usual, with the exception that the
requests will be passed through puffs both in the kernel and userspace:

ftp.netbsd.org:/pub on /puffs type puffs|p2k|puffs|psshfs

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.

Use linker script to make __start/stop_link_set_modules be present
in libs built with binutils >=2.19. This is a less error-prone
method than the previous where components had to be tagged in the
Makefile as modules (and if they weren't, things broke. and vice
versa).

binutils 2.19 has changed the old behaviour of defining __start_SECTNAME
for orphaned sections to using PROVIDE. What this means is that
unless a rump component internally references that symbol, it will
not be included in the component shared library, and hence cannot
be referenced when the component is loaded. Add a workaround which
works both with 2.16 and 2.19: force a reference to the __start
symbol internally and hence retain it in the resulting library.

Install rump libraries and utilities to the base system and remove the
private non-installed build infrastructure from sys/rump.

breakdown of commit:
* install relevant headers into /usr/include/rump
* build sys/rump/librump/rumpuser and sys/rump/librump/rumpkern
from src/lib and install as librumpuser and librump, respectively
+ this retains the ability to test a librump build with just the
kernel sources at hand
* move sys/rump/fs/lib/libukfs and sys/rump/fs/lib/libp2k to src/lib
for general consumption, they are not kernel-space dwellers anyway
* build and install sys/rump/fs/lib/lib$fs as librumpfs_$fs
* add chapter 3 manual pages for rump, rumpuser, ukfs and p2k
* build and install userspace kernel file system daemons if MKPUFFS=yes
is spexified
* retire fsconsole for now, it will make a comeback with an actually
implemented version shortly

Introduce RUMPs - Runnable Userspace Meta-Programs

/sys/rump contains programs which run unmodified kernel code in an
emulated userspace environment. The kernel environment is provided
by librump. Currently supported are a number of file systems,
which by using puffs integrate seamlessly into the system and
provide a similar user experience to if the code was running as
part of the kernel. Potential future rumpification targets include
for example parts of the networking stack and some device drivers.

This work was supported by Google Summer of Code 2007.

Support fifofs in rump. Do not include it in rumpvfs directly,
since it involves some very non-fs'y components like sockets and
local domain networking. Also (for better or worse?), call it
rump*v*fs_fifofs instead of rumpfs_fifofs, since it does not really
provide a file system driver.

XXX: uses duplicate common symbols and functionality depends on
link order ... (but at least it works better than before this change)

Document the fcntl calls better in lfs.h. Bounds-check inode numbers in
segment parsing functions. Use the in-kernel cleaner in a greedy mode
for tests in tests/fs/vfs, and add a test of the kernel cleaner.

Drop -O[01] hacks for vax; no longer necessary for patched GCC 10

PR port-vax/57646: Import major vax toolchain fix by Kalvis Duckmanton

XXXRO: GCC 12 may require hacks for a while, but it turned out that
GCC 12 should be treated differently from older versions; a lot of new
files need -O[01] flags, while some may no longer require it.

I will take a look later.

Note that these hacks are not required if Kalvis's patches for GCC 12
are applied.

Keep doc/HACKS entries for a while (will be sync with update for GCC 12).

remove GCC_NO_ADDR_OF_PACKED_MEMBER for several subdir builds
that are now handled by lfs_accessors.h internally.

add support for new GCC 9 warnings that may be too much to fix
right now. new address-of-packed-member and format-overflow
warnings have new GCC_NO_ADDR_OF_PACKED_MEMBER amd
GCC_NO_FORMAT_OVERFLOW variables to remove these warnings.

apply to a bunch of the tree. mostly, these are real bugs that
should be fixed, but in many cases, only by removing the 'packed'
attribute from some structure that doesn't really need it. (i
looked at many different ones, and while perhaps 60-80% were
already properly aligned, it wasn't clear to me that the uses
were always coming from sane data vs network alignment, so it
doesn't seem safe to remove packed without careful research for
each affect struct.) clang already warned (and was not erroring)
for many of these cases, but gcc picked up dozens more.

Suppress spurious address-of-packed error in rump lfs too.

elide vax compiler bug.

Add a COMMENT describing what each component roughly does.

"make describe" prints the comment.

Requested/inspired by Vincent Schwarzer on rumpkernel-users

Change lfs from hash table to vcache.

- Change lfs_valloc() to return an inode number and version instead of
a vnode and move lfs_ialloc() and lfs_vcreate() to new lfs_init_vnode().

- Add lfs_valloc_fixed() to allocate a known inode, used by kernel
roll forward.

- Remove lfs_*ref(), these functions cannot coexist with vcache and
their commented behaviour is far away from their implementation.

- Add the cleaner lwp and blockinfo to struct ulfsmount so lfs_loadvnode()
may use hints from the cleaner.

- Remove vnode locks from ulfs_lookup() like we did with ufs_lookup().

branches: 1.11.4;
Move lfs_getpages and lfs_putpages to their own file.

branches: 1.10.2;
Merge riastradh-drm2 to HEAD.

why does rump have to have its own private build system?

branches: 1.8.2; 1.8.4;
right, why does rump have to have its own copy of all the build information?

Cleanups and hacks to make lfs userland stuff build:
- lfs_cksum.c doesn't actually need ulfs_inode.h any more.
- neither does lfs_itimes.c.
- add hacks to fsck_lfs to make it compile.
- add hacks to newfs_lfs to make it compile.
- fix warning in ulfs_quota.c when quotas are fully disabled
(as I guess is happening with the rumpity version)

XXX: This commit adds -I${NETBSDSRCDIR}/sys to the Makefiles for
XXX: fsck_lfs, newfs_lfs, and lfs_cleanerd. This needs to be cleaned
XXX: up ASAP; but I consider this less problematic in the short term
XXX: than spewing ulfs_*.h into /usr/include.

branches: 1.6.10; 1.6.20;
Globally define -Wno-pointer-sign, as it has become a pointless
exercise of "add it to every Makefile individually".

branches: 1.5.14;
Install rump libraries and utilities to the base system and remove the
private non-installed build infrastructure from sys/rump.

breakdown of commit:
* install relevant headers into /usr/include/rump
* build sys/rump/librump/rumpuser and sys/rump/librump/rumpkern
from src/lib and install as librumpuser and librump, respectively
+ this retains the ability to test a librump build with just the
kernel sources at hand
* move sys/rump/fs/lib/libukfs and sys/rump/fs/lib/libp2k to src/lib
for general consumption, they are not kernel-space dwellers anyway
* build and install sys/rump/fs/lib/lib$fs as librumpfs_$fs
* add chapter 3 manual pages for rump, rumpuser, ukfs and p2k
* build and install userspace kernel file system daemons if MKPUFFS=yes
is spexified
* retire fsconsole for now, it will make a comeback with an actually
implemented version shortly

Introduce RUMPs - Runnable Userspace Meta-Programs

/sys/rump contains programs which run unmodified kernel code in an
emulated userspace environment. The kernel environment is provided
by librump. Currently supported are a number of file systems,
which by using puffs integrate seamlessly into the system and
provide a similar user experience to if the code was running as
part of the kernel. Potential future rumpification targets include
for example parts of the networking stack and some device drivers.

This work was supported by Google Summer of Code 2007.

bsd.own.mk: rename to CC_WNO_ADDRESS_OF_PACKED_MEMBER

Provide a single variable
CC_WNO_ADDRESS_OF_PACKED_MEMBER
with options for both clang and gcc, to replace
CLANG_NO_ADDR_OF_PACKED_MEMBER
CC_NO_ADDR_OF_PACKED_MEMBER
GCC_NO_ADDR_OF_PACKED_MEMBER

Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.

Move msdosfs_rename() and doscheckpath() to new file msdosfs_rename.c.

No functional change.

add support for new GCC 9 warnings that may be too much to fix
right now. new address-of-packed-member and format-overflow
warnings have new GCC_NO_ADDR_OF_PACKED_MEMBER amd
GCC_NO_FORMAT_OVERFLOW variables to remove these warnings.

apply to a bunch of the tree. mostly, these are real bugs that
should be fixed, but in many cases, only by removing the 'packed'
attribute from some structure that doesn't really need it. (i
looked at many different ones, and while perhaps 60-80% were
already properly aligned, it wasn't clear to me that the uses
were always coming from sane data vs network alignment, so it
doesn't seem safe to remove packed without careful research for
each affect struct.) clang already warned (and was not erroring)
for many of these cases, but gcc picked up dozens more.

Introduce RUMPs - Runnable Userspace Meta-Programs

/sys/rump contains programs which run unmodified kernel code in an
emulated userspace environment. The kernel environment is provided
by librump. Currently supported are a number of file systems,
which by using puffs integrate seamlessly into the system and
provide a similar user experience to if the code was running as
part of the kernel. Potential future rumpification targets include
for example parts of the networking stack and some device drivers.

This work was supported by Google Summer of Code 2007.

Import read-only part of the NiLFS (v2) implementation for NetBSD. It has been
tested with a DEBUG+DIAGNOSTIC+LOCKDEBUG kernel. To summerise NiLFS, i'll
repeat my posting to tech-kern here:

NiLFS stands for New implementation of Logging File System; LFS done
right they claim :) It is at version 2 now and is being developed by NTT, the
Japanese telecom company and recently put into the linux source tree. See
http://www.nilfs.org. The on-disc format is not completely frozen and i expect
at least one minor revision to come in time.

The benefits of NiLFS are build-in fine-grained checkpointing, persistent
snapshots, multiple mounts and very large file and media support. Every
checkpoint can be transformed into a snapshot and v.v. It is said to perform
very well on flash media since it is not overwriting pieces apart from a
incidental update of the superblock, but that might change. It is accompanied
by a cleaner to clean up the segments and recover lost space.

My work is not a port of the linux code; its a new implementation. Porting the
code would be more work since its very linux oriented and never written to be
ported outside linux. The goal is to be fully interchangable. The code is non
intrusive to other parts of the kernel. It is also very light-weight.

The current state of the code is read-only access to both clean and dirty
NiLFS partitions. On mounting a dirty partition it rolls forward the log to
the last checkpoint. Full read-write support is however planned!

Just as the linux code, mount_nilfs allows for the `head' to be mounted
read/write and allows multiple read-only snapshots/checkpoint mounts next to
it.

By allowing the RW mount at a different snapshot for read-write it should be
possible eventually to revert back to a previous state; i.e. try to upgrade a
system and being able to revert to the exact state prior to the upgrade.

Compared to other FS's its pretty light-weight, suitable for embedded use and
on flash media. The read-only code is currently 17kb object code on
NetBSD/i386. I doubt the read-write code will surpass the 50 or 60. Compared
this to FFS being 156kb, UDF being 84 kb and NFS being 130kb. Run-time memory
usage is most likely not very different from other uses though maybe a bit
higher than FFS.

and becomes interesting with the fs-utils project. We can now do

In other words, this provides total integration for "normal"

library level.

Note: implementation is still "first stab" and the fs-utils usage
will no doubt change.

Add the ability to run puffs in userspace. This means that puffs

(I hate emulators, they are annoyingly clumsy).

To e.g. mount psshfs using puffs-on-puffs, run fs/bin/syspuffs/syspuffs
with the regular mount_psshfs command line as an argument:

golem> ./syspuffs /usr/sbin/mount_psshfs ftp.netbsd.org:/pub /puffs

This will make the mount appear as usual, with the exception that the
requests will be passed through puffs both in the kernel and userspace:

Put the kernelside rump kernel headers into <rump-sys> instead of
sprinkling them around the faction directories. Avoids having
to add a CPPFLAGS (or several) to pretty much every component

Introduce RUMPs - Runnable Userspace Meta-Programs

/sys/rump contains programs which run unmodified kernel code in an
emulated userspace environment. The kernel environment is provided
by librump. Currently supported are a number of file systems,
which by using puffs integrate seamlessly into the system and
provide a similar user experience to if the code was running as
part of the kernel. Potential future rumpification targets include
for example parts of the networking stack and some device drivers.

This work was supported by Google Summer of Code 2007.

adapt to ${CC_WNO_ADDRESS_OF_PACKED_MEMBER}

Simplify CWARNFLAGS to use ${CC_WNO_ADDRESS_OF_PACKED_MEMBER}
which works for both clang and gcc, and remove compiler-specific
equivalents.

bsd.own.mk: rename to CC_WNO_ADDRESS_OF_PACKED_MEMBER

Provide a single variable
CC_WNO_ADDRESS_OF_PACKED_MEMBER

CLANG_NO_ADDR_OF_PACKED_MEMBER
CC_NO_ADDR_OF_PACKED_MEMBER
GCC_NO_ADDR_OF_PACKED_MEMBER

Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.

add support for new GCC 9 warnings that may be too much to fix
right now. new address-of-packed-member and format-overflow
warnings have new GCC_NO_ADDR_OF_PACKED_MEMBER amd
GCC_NO_FORMAT_OVERFLOW variables to remove these warnings.

apply to a bunch of the tree. mostly, these are real bugs that
should be fixed, but in many cases, only by removing the 'packed'
attribute from some structure that doesn't really need it. (i
looked at many different ones, and while perhaps 60-80% were
already properly aligned, it wasn't clear to me that the uses
were always coming from sane data vs network alignment, so it
doesn't seem safe to remove packed without careful research for
each affect struct.) clang already warned (and was not erroring)
for many of these cases, but gcc picked up dozens more.

Disable a couple of warnings until further investigation.
