Move rump kernel man pages from various sources to sys/rump

namely:
* src/lib is used only when building for POSIX'y platforms, but

the POSIX'y implementation hosted in src/lib/librumpuser

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.

Note that the ioctl SIOCGIFINFO_IN6 no longer sets flags. That now
needs to be done using the pre-existing SIOCSIFINFO_FLAGS ioctl.

Compat is fully provided where it makes sense, but trying to turn on
RA handling will obviously throw an error as it no longer exists.

Note that if you use IPv6 temporary addresses, this now needs to be
turned on in dhcpcd.conf(5) rather than in sysctl.conf(5).

implement 32-bit compat support for raidframe.

convert several raidframe ioctls to be bitsize idempotent so that
they work the same in 32 and 64 bit worlds, allowing netbsd32 to
configure and query raid properly. remove useless 'row' in a few
places. add COMPAT_80 and put the old ioctls there.

raidframeio.h:
RAIDFRAME_TEST_ACC
- remove, unused
RAIDFRAME_GET_COMPONENT_LABEL
- convert to label not pointer to label
RAIDFRAME_CHECK_RECON_STATUS_EXT
RAIDFRAME_CHECK_PARITYREWRITE_STATUS_EXT
RAIDFRAME_CHECK_COPYBACK_STATUS_EXT
- convert to progress info not pointer to info
RAIDFRAME_GET_INFO
- version entirely.
raidframevar.h:
- rf_recon_req{} has row, flags and raidPtr removed (they're
not a useful part of this interface.)
- RF_Config_s{} and RF_DeviceConfig_s{} have numRow/rows removed.
- RF_RaidDisk_s{} is re-ordered slightly to fix alignment
padding - the actual data was already OK.
- InstallSpareTable() loses row argument

rf_compat32.c has code for RF_Config_s{} in 32 bit mode, used
by RAIDFRAME_CONFIGURE and RAIDFRAME_GET_INFO32.

rf_compat80.c has code for rf_recon_req{}, RF_RaidDisk_s{} and
RF_DeviceConfig_s{} to handle RAIDFRAME_FAIL_DISK,
RAIDFRAME_GET_COMPONENT_LABEL, RAIDFRAME_CHECK_RECON_STATUS_EXT,
RAIDFRAME_CHECK_PARITYREWRITE_STATUS_EXT,
RAIDFRAME_CHECK_COPYBACK_STATUS_EXT, RAIDFRAME_GET_INFO.

move several of the per-ioctl code blocks into separate functions.

add rf_recon_req_internal{} to replace old usage of global
rf_recon_req{} that had unused void * in the structure, ruining
it's 32/64 bit ABI.

add missing case for RAIDFRAME_GET_INFO50.

adjust raid tests to use the new .conf format, and add a case to
test the old method as well.

raidctl:
deal with lack of 'row' members in a couple of places.
fail request no longer takes row.
handle "START array" sections with just "numCol numSpare", ie
no "numRow" specified. for now, generate old-style configuration
but update raidctl.8 to specify the new style (keeping reference
to the old style.)

note that: RF_ComponentLabel_s::{row,num_rows} and
RF_SingleComponent_s::row are obsolete but not removed yet.

There are tests which rely on compat code continuing to be present,
so default RUMP_NBCOMPAT to all releases.

reported by gson

Rename RUMP_COMPAT to RUMP_NBCOMBAT to better signify what the
variable does.

For RUMP_COMPAT, accept "all" as an alias.

Also accept a comma-separated list, since that's easier to pass through
shells than a whitespace-separated list.

Default compat to 60 70, now that it hopefully generates no fallout.

Put 50 back to compat list for a while (some fallout)

Define rump_nativeabi_p() under arch, where one would logically expect
it to be defined.

default compat to 60 & 70

Generate -DCOMPAT_nn from a list of nn provided in RUMP_COMPAT

Remove shlib_version files and just use Makefile SHLIB_MAJOR/MINOR,

RUMPCOMP_USER has been deprecated for long enough, remove it.

branches: 1.99.4;
Implement rumpcomp_sync_icache() hyprecall for mips and add
a barebone implementation if mips cache ops to librumpkern_sljit.

Some rump kernel components for interfacing with the environment need
to access both NetBSD kernel facilities and facilities provided by the
environment.

Where the environment's headers can be #included without namespace
conflict (which can be done - with care - for some Xen mini-os
headers), it is convenient to simply allow the rump kernel code to
call directly into the environment.

This also requires not mangling the symbol names.

So provide a variable RUMP_SYM_NORENAME which can be set by a component
namefile to a series of symbols or symbol prefixes (in makefile-quoted
awk regexp syntax). For example, in the rumpuser-xen xenbus driver:
RUMP_SYM_NORENAME=xenbus_|HYPERVISOR_|wake$$|block$$|schedule$$|force_evtchn

Signed-off-by: Ian Jackson <Ian.Jackson@eu.citrix.com>
(proposed on rumpkernel-users; very minor modification by myself)

Remove old HAVE_SUN_LD compat handling, it was there long enough.

Add a RUMP_USE_CTOR compile-time switch. If defined, use
__attribute__((constructor)) to determine which rump kernel components
and kernel modules are linked into the rump kernel. If not defined
(default), use the regular approach with link sets.

This option is aimed to fix problems with toolchains where using link
sets is not possible because the linker does not generate the requisite
__start/__stop symbols for the link set sections (e.g. GNU gold, OS X, ...).

add multi-inclusion protection

branches: 1.94.2;
Introduce RUMP_CURLWP compile option to select curlwp scheme.
Default is still "hypercall".

Allow RUMP_LDSCRIPT itself to be used to specify which ldscript to use.
HAVE_SUN_LD will be deprecated in the future.

Allow compile-time optimizations to curlwp. This can have a pretty
staggering impact on performance. When running sendto() in a loop,
the improvement is 200k more calls per second with an inlined __thread
curlwp as opposed to the default. In other words, it shaves off hundreds
of CPU cycles per call (~20%). Even just eliminating the x86_curlwp()
call in favor of an inline gives an improvement of 60k calls per second.

Allow multiple "rumpcomp_user" source modules to be specified by
introducing RUMPCOMP_USER_SRCS. Make RUMPCOMP_USER issue a deprecation
warning, but for compat make it set RUMPCOMP_USER_SRCS=rumpcomp_user.c
for now.

Move the "is arch capable of loading native kernel modules into
rump kernel" clauses from bsd.own.mk to Makefile.rump. Also,
add a rump_nativeabi_p() call to determine if rump kernel is
compiled with native ABI support.

Make ktrace a compile-time option

Support ktrace for rump kernels.

RUMPCOMP_USEROBJ -> RUMPOBJ_NORENAME

Widens the implied usage scope of the variable.

Rename RUMPTEST_BUILDSH to RUMPKERN_ONLY. Turns out not building any
POSIX implementations of hypercalls is useful beyond the build.sh test,
such as when building rump kernels for non-POSIX hosts.

The linker script is the argument of -T, so keep them together.

explain to me)

Allow to completely skip the ldscript, useful for linkers that don't need one.

fix typo

order too

uniquefy, really should fix this so there are no dup rules.

Fix the build w/o DESTDIR

one more typofix

On second thought, let's use make syntax in makefiles ...

Use correct ldscript etc. for Sun ld.

Use "-isysroot ${DESTDIR}" for RUMPCOMP_USER when run as part of build.sh
so as to catch the necessary headers, which, unlike in the buildrump.sh
case, are not supposed to be intermingled with the ones provided by
the host.

Shuffle the namespaces in the previous around a bit, and make it
rumpcomp_user instead of rumpuser_component. This makes sure the
rumpuser namespace is used only by librumpuser.

Allow rump kernel components to define their own hypercalls. This is
useful for example for supporting the tap device on Linux, for which
Linux-specific ioctl's are required (or at least so I was told).

Pass linker script with -Wl,-T to avoid clang incompating itself out
without flagging an error.

Instead of maintaining an evergrowing list of -U's, leave that up
to an external script.

Don't duplicate arbitrary chunks of bsd.sys.mk in here (especially
-Wsign-compare, since that doesn't even work with the kernel, and was
just previously masked by -isystem). Reorder a bit too.

Don't unconditionally use the error-silencing magic of -isystem
(as opposed to -I) on every component, only the zfs ones depend on it
to build. Regular modules might benefit from a similar move.

it gets rid of many of the warnings trying to link rump_cd9960, but
there are a bunch remaining. atomic ops seem missing, and some ktrace
points.

Move make snippets for use with config(1) ioconf functionality from
rump into share/mk. This is to make it useful for all kernel
builders.

Note: we have waaay too many weird and wonderful ways of making
kernel code (monolithic kernel, modules, rump). There should be
only one way to build kernel code instead of a maze of twisty little
.mk files, all not quite alike. When that is fixed, this snippet can go
into the more generic .mk file.

branches: 1.52.2;
Rename IOCONFIG to IOCONF. It matches the config(1) keyword and
aligns better in Makefiles.

Invert inverted comment and verbosify it.

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

XXX: should autosynchronize with the rest of the kernel buildflags
in sys/conf/Makefile.kern.inc.

IOCONFIG comes from .CURDIR

branches: 1.48.2;
add a rule for locators.h too

If IOCONFIG is defined, autogenerate ioconf.c and locators.h
from ${IOCONFIG}.

Make (no pun intended) it possible to perform component symbol
protection from a shell prompt with the command line:

make -f /sys/rump/Makefile RUMP_SYMREN=module.kobj

This is benefitial especially on i386, where rump ABI matches the
kernel ABI (sans the renaming isolation). In the above example
module.kobj can then be loaded in a rump kernel either statically
at link-time simply by giving module.kobj as an object to the
linker, or dynamically at runtime by calling rump_sys_modctl(MODCTL_LOAD).

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).

Include arch/include/Makefile.inc for some compiler flags.

Hmm, in addition to leaving out -lc, -nostdlibs also leaves out
libgcc, and causes problems on some platforms. Currently there is
no easy way to say "link against libgcc but not against libc", so
just comment out -nostdlibs until a better way is invented.

Don't link rump kernel libs against libc. They have no host system
dependencies apart from indirect ones via rumpuser.

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.

kernel code needs -Wno-format-zero-length

Always define __NetBSD__ (for builds on non-NetBSD)

define DEBUGPRINT

prettyprint long line, no functional change

More reproducible build fixes:

1) invoke objcopy with --preserve-dates or it will update all the
dates in the .a file to the present date.
2) add an invocation of ar-as-ranlib or the object file index ends up
with the date in it. (it might also end up with an incorrect
index.)

remove RANLIB too. pointed out by perry.

Reflect the change to archivebuild in bsd.lib.mk rev 1.296 for
deterministic builds, as hinted by perry.

Drop to WARNS?=3 as src/sys doesn't compile with -Wsign-compare yet

branches: 1.32.2;
* enable COMPAT_50 (we need a better compat model here, but this is
enough for now)
* _RUMPKERNEL is not going anywhere anymore, so adjust comment

Change the use of formally undocumented features, which have now been
made to fail. Specifically, change
.ifdef(SYMBOL) -> .ifdef SYMBOL or .if defined(SYMBOL),
and corresponding for .ifndef.

Also correct one error in lib/libm/Makefile (.ifdef (${MKCOMPLEX} != "no")?!?).

Do rump kernel symbol protection for vax. All archs support it now.

* Add adapted version of the userspace atomic_cas ops for platforms
lacking special instructions. We always use the spinlocked version
(could use RAS on UP NetBSD host, but it's not portable).
* Add platform-based symbol quirk tables for selectively not renaming
toolchain symbols for some platforms. Although, this should really
depend on the (toolchain,platform)-tuple and not just the platform.

This allows arm, hppa, mips and sh3 to build succesfully with an
isolated rump kernel namespace. ... now, one arch remains: vax.
you must compile vax. then, only then will you MI be.

Treat all of ^__ as compiler namespace and do not rename those
symbols. This fixes e.g. fortify and sh3 millicode issues. This
is still not perfect, however, since e.g. the MIPS _gp_disp is not
in ^__.

XXX: we provide a few ^__ symbols in the kernel, but those can be
easily renamed. The harder problem is how to keep the kernel clean
of those afterwards.

* sparc supports rump kernel symbol rename
* plonk vax in here since it has issues with rename

Disable symbol renaming for now on arm, mips, sh3 and sparc to
allow them to build. Some libgcc symbols are being renamed also,
plus not all atomic operations are provided by libkern on these
archs.

Add Makefile.rump to DPSRCS. Should solve issues with UPDATE=1 builds.

Rename symbols in rump kernel libraries to always belong to a "rump"
symbol namespace. This has several implications:
* no symbols are accidentally linked against host platform libraries
* all host platform access is done via rumpuser, and hence the
portability of rump is now well defined
* functionality such as proplib can now exist within the rump virtual
kernel and the application using it

Thanks to uwe for originally suggesting the bulk renaming approach
over a pint of what I believe was very crisp, curious and untypical
stout. It had an almost acidic characteristic with fruity notes
and lacking dark and roasted flavours.

And thanks to lukem for pointing me in the right direction with make.

Define -DMODULAR in Makefile.rump instead of the sys/rump/librump

Purge multiple kernel opt files.

Move list of rump-uses-kmod archs to bsd.own.mk for wider consumption.

Switch amd64 rumps to the kernel ABI.

Switch i386 away from rump/include/machine. This means that rump
on i386 now uses the native kernel ABI. This in turn means that
rump modules and kernel modules are binary equivalent and can be
used interchangeably.

We are conseptually a module, so -D_MODULE. Group CPPFLAGS better.

Pick PPC_OEA over PPC_IBM4XX. I've decided I like it more.
(plus it hopefully builds without source changes)

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

inspired by a buildrump.sh bug report due to an out-of-date src

Teach rump how to process __link_set_sysctl_funcs so it can handle
modules the same as a real kernel.

Partly addresses PR kern/55088 - __link_set_evcnts not yet handled
(that will happen later)

domains are attached by module(-like) constructors, so no need to
play link_set games with them.

Introduce RUMP_COMPONENT. It behaves mostly like a simplified
module which is linked into the kernel and cannot be unloaded.
The main purpose is to get the proper constructors run and create
any /dev nodes necessary for said component. Once more of the
kernel (e.g. networking stack and device drivers) are converted to
MODULE and devfs pops up from somewhere, rump components can be
retired.

branches: 1.1.2;
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).

typo: ARCH_EXTRA -> ARCHS_EXTRA

Add ews4800mips and sh3 heads only listed in src/tools/Makefile.nbincludes.

Make include_headerlist ignore files in already exported directories.
Invoke include_headerlist after exporting the ARCHS directories.

Summary: export the files from headerlist before the ARCHS's includes.
Or else cvs export will complain about them being in the way.

Summary: add the files from src/tools/headerlist to the output.

Summary: pax needs pack_dev.h from mknod. move mknod to sys sources

Add uname to rump sources

add brconfig to userland utils

add mixerctl to userland utils

Add libkvm to list of userspace libraries.

Even though kvm per se isn't support by rump kernels at least for now,
libkvm contains methods such as kvm_getproc2() which can be necessary for
compiling existing applications with kvm awareness as rumprun unikernels.

include sockstat in list of utilities

Add risc-v to checked out rump architectures

add libc++

Add rtadvd to rump user sources

Add fdisk to rump listsrcdirs

Add mdconfig to rump listsrcdirs

include lib/i18n_module in user sources

It's used by the libc build to determine the citrus module version,
so including it will give us consistent results both with a full
NetBSD checkout and a rumprun things only checkout.

Add genassym

It's not reeeaaallly required currently, but libc build for some archs
(e.g. arm) wants to run it, and genassym is small enough for it to be
simplest to just include it.

branches: 1.22.2;
Add libelf to rump directories

Perform internal consistency check automatically.

Revert, zfs was already elsewhere in list

Add zfs files to rump userspace sources

Add aarch64 to rump srcdirs

Make the file system utility list consistent between fsck, mount and newfs.
For now, include ext2, ffs and msdosfs (and as a "special case", mount_tmpfs).

split "sys" further into "sys" and "posix", per comments from justin

In addition to kernel/tools sources, include another selection of sources
useful for running application stacks on rump kernels.

Add cat, rpcgen and stat to TOOLS_BUILDRUMP. They're useful for
installing headers for the app stack cases that need it done, and small
enough to not matter for the kernel-only cases that don't.

+rump_server

building ARM rump kernels now requires sys/arch/arm/arm32

Include powerpc+evbpcc. Allows the buildrump.sh checkout to work on
powerpc machines. Tested on Linux/ppc64 by Justin Cormack.

Include Makefiles under sys/arch.

This makes it easy to install the set of kernel headers that were used
by buildrump.sh. Requested by Justin Cormack for ljsyscall (Lua interface
definitions).

branches: 1.4.6;
add librumphijack to the list

of src/sys.

Avoid dependency on curlybrace expansion.

branches: 1.1.4;
Move the list of source directories required by TOOLS_BUILDRUMP=yes from
the buildrump.sh repo to here. While I don't expect the list to change

Split scsipi out of librumpdev_umass into librumpdev_scsipi. umass
still compile time depends on scsipi in the sense of "ifdef
NATAPIBLUES", but I'm not going to fix that now.

Make putter its own component: rumpdev_putter. It was coupled in
with rumpfs_puffs for prehistoric reasons which are no longer valid
(namely, only fs components existed back then and there was no /dev
support in rump fs namespace).

remember to add audio to the list of device components

support pad(4)

USB bluetooth device rump component.

This is a curious driver in the sense that unlike all other current
device drivers, it does not require vfs. This is because the driver
is controlled via bluetooth, which is controlled via PF_BLUETOOTH
sockets (as opposed to a /dev node).

- Split playback and record cleanly. Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism. The encoding/channels/frequency

XXX kernel ABI change to devsw_detach signature requires bump

Fix regression introduced in tests/net/bpf and tests/net/bpfilter

The rump code needs to call devsw_attach() in order to assign a dev_major
for bpf; it then uses this to create rumps /dev/bpf node. Unfortunately,
this leaves the devsw attached, so when the bpf module tries to initialize
itself, it gets an EEXIST error and fails.

So, once rump has figured what the dev_major should be, call devsw_detach()
to remove the devsw. Then, when the module initialization code calls
devsw_attach() it will succeed.

In retrospect, putting bpf under the dev faction wasn't the smartest

detach the [bc]devsw's because normal module initialization will do its
own attachment, and we don't want that to fail.

XXX kernel ABI change to devsw_detach signature requires bump

We no longer need ioconf.c - remove it to avoid "defined but not used"
compiler error.

Don't call the drvctl module's initialization code during rump component
initialization. Instead, temporarily attach the drvctl's cdevsw to
determine its device c-major, create the /dev/drvctl node using that
c-major, and then detach. This leaves things in a state where normal
module initialization can run.

Since we're now creating the /dev/drvctl device node correctly, we don't
need to create it again. So mark the device as DEVNODE_DONTBOTHER in
the devsw_conv0 conversion table.

This bug was introduced more than a year ago (src/sys/kern/kern_drvctl.c
rev 1.40), but was silently ignored except when running a rump_server

For device modules that provide both auto-config and /dev/xxx
interfaces, make sure that initialization and destruction
follow the proper sequence. This is triggered by the recent
changes to the devsw stuff; per riastradh@ the required call
sequence is:

devsw_attach()
config_init_component() or config_cf*_attach()
...
config_fini_component() or config_cf*_detach()
devsw_detach()

While here, add a few missing calls to some of the detach
routines.

1. compile without build break
2. no related test failures from atf

with the default provided by Makefile.rump (they're all 0.0 anyway)

branches: 1.1.2; 1.1.4; 1.1.6; 1.1.24; 1.1.42;
support pad(4)

Avoid '.' in variable names which are expected to be passed to
this Makefile via the env.

That character is strictly speaking not allowed by POSIX in an exported
variable name, and at least dash >= 0.58 refuses to export such variables.

Furthermore, since the individual CFLAGS/CPPFLAGS/etc. variables
are not comprehensive enough for all cases (e.g. HURD), just
support the .includable version from now on, i.e.
RUMPCOMP_MAKEFILEINC_rumpdev_pci.

curious failure mode debugged by Martin Lucina

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
Makefile.

Leave compat headers around in the old locations.

The commit changes some autogenerated files, but I'll fix the
generators shortly and regen.

Allow PCI implementers to specify arbitrary makefile constructs.

Add a COMMENT describing what each component roughly does.

"make describe" prints the comment.
