This patch adds support for Unix98 pseudo terminals, that is,
posix_openpt(3), grantpt(3), unlockpt(3), /dev/ptmx, and /dev/pts/.
The latter is implemented with a new pseudo file system, PTYFS.
In effect, this patch adds secure support for unprivileged pseudo
terminal allocation, allowing programs such as tmux(1) to be used by
non-root users as well. Test77 has been extended with new tests, and
no longer needs to run as root.
The new functionality is optional. To revert to the old behavior,
remove the "ptyfs" entry from /etc/fstab.
Technical nodes:
o The reason for not implementing the NetBSD /dev/ptm approach is that
implementing the corresponding ioctl (TIOCPTMGET) would require
adding a number of extremely hairy exceptions to VFS, including the
PTY driver having to create new file descriptors for its own device
nodes.
o PTYFS is required for Unix98 PTYs in order to avoid that the PTY
driver has to be aware of old-style PTY naming schemes and even has
to call chmod(2) on a disk-backed file system. PTY cannot be its
own PTYFS since a character driver may currently not also be a file
system. However, PTYFS may be subsumed into a DEVFS in the future.
o The Unix98 PTY behavior differs somewhat from NetBSD's, in that
slave nodes are created on ptyfs only upon the first call to
grantpt(3). This approach obviates the need to revoke access as
part of the grantpt(3) call.
o Shutting down PTY may leave slave nodes on PTYFS, but once PTY is
restarted, these leftover slave nodes will be removed before they
create a security risk. Unmounting PTYFS will make existing PTY
slaves permanently unavailable, and absence of PTYFS will block
allocation of new Unix98 PTYs until PTYFS is (re)mounted.

Removes the following man pages:
* awk.1x -- for a version of awk we no longer have
* kermit.1x -- seems gone altogether
* macros.1x -- not useful for anyone anymore
Moves the following man pages:
* mined.1x -- Moved to minix/commands/mined/mined.1
and reformatted to use the mdoc macros instead of the
Minix macros so that it displays properly.
Removes /usr/man/man1x from the directory tree.

With the import of Xorg, a proper separation between login-time and sub
shell-time of the environment setup is necessary.
Instead of re-developping this from scratch, I am taking the opportunity
to import the NetBSD default environment.

We have to use SOCK_SEQPACKET instead of SOCK_STREAM for client/server
communication, because UDS does things with control messages that tmux
does not expect.

/etc/profile enables by default tabcompletion, as well as emacs mode,
in order to keep the old MINIX ash behavior.
Note: The shell now refuses to source a script without a relative or
absolute path.
This means:
- '. myscript.sh' fails, while
- '. ./myscript.sh' succeeds

The bin user doesn't need an actual home folder to run the tests. As
such this account should not be used in 'su - bin'. To be noted that
'su bin' still works as expected, and allow to run the minix test set
as usual.

We used to have an account "ast" as a token to Andrew S. Tannebaum,
the creator of MINIX. The account was disable by default, with no
possible way to login.
It seems it generates more confusion than it is worth, so this removes it.
The default skeleton user profile is still stored into /etc/ast instead
of the usual /etc/skel.

- Fix for possible unset uid/gid in toproto
- Fix for default mtree style
- Update libelf
- Importing libexecinfo
- Resynchronize GCC, mpc, gmp, mpfr
- build.sh: Replace params with show-params.
This has been done as the make target has been renamed in the same
way, while a new target named params has been added. This new
target generates a file containing all the parameters, instead of
printing it on the console.
- Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)

* /usr/bin/strip would be replaced by a link, even when compiling
binutils.
* Updated minix-spec.h to use the correct dynamic linker, and removed
the previously used symlinks.
* Removed the patch to the builtin PATH of ld.elf_so.

- fail SEF initialization if any of the subtests failed, so that the
party invoking the "service up" can tell whether the test succeeded;
- add "nocontig" option, because VM isn't particularly good at
allocating contiguous memory;
- add "silent" option, because it floods the console otherwise;
- allow the device size to be smaller than the maximum transfer size;
- install files to installed test directory.

The BeagleBone Weather cape enhances the BeagleBone's capabilities
by providing environment sensors (temperature, humidity, pressure,
and ambient light level).
The weatherstation demo is a port of the bonescript weatherstation
to Minix. It provides a nice visual display of the sensor data in
a web browser.
The code is installed to /usr/share/beaglebone/weather on 'earm'
and an embedded web server is started at boot time on port 80
when the cape is attached. Further details are provided in the
README.txt file.

To do so, a few dependencies have been imported:
* external/bsd/lutok
* external/mit/lua
* external/public-domain/sqlite
* external/public-domain/xz
The Kyua framework is the new generation of ATF (Automated Test
Framework), it is composed of:
* external/bsd/atf
* external/bsd/kyua-atf-compat
* external/bsd/kyua-cli
* external/bsd/kyua-tester
* tests
Kyua/ATF being written in C++, it depends on libstdc++ which is
provided by GCC. As this is not part of the sources, Kyua is only
compiled when the native GCC utils are installed.
To install Kyua do the following:
* In a cross-build enviromnent, add the following to the build.sh
commandline: -V MKBINUTILS=yes -V MKGCCCMDS=yes
WARNING:
At this point the import is still experimental, and not supported
on native builds (a.k.a make build).
Change-Id: I26aee23c5bbd2d64adcb7c1beb98fe0d479d7ada
-By adding MKGCC=yes and MKGCCCMDS=yes on the make commandline
it is now possible to compile and install GCC on the system.
Before doing this, if you are not using the build.sh script,
you will need to call the fetch scripts in order to retrieve
the sources of GCC and its dependencies.
-Reduce difference with NetBSD share/mk
Move Minix-specific parameters from bsd.gcc.mk to bsd.own.mk,
which is anyway patched, so that bsd.gcc.mk is now aligned
on the NetBSD version.
-Clean libraries dependencies, compiles stdc++ only if gcc is
also compiled (it is part of the gcc sources)
-Correct minix.h header sequence, cleanup spec headers.
-Fix cross-compilation from a 32bit host targeting MINIX/arm
Change-Id: I1b234af18eed4ab5675188244e931b2a2b7bd943
- Enable installing binutils from the base system.
- Import texinfo which is required for the binutils tools
to be compiled.
- Also adapted the fetch rules to correctly generate the
gitignore files for gcc, and allow the case of multiple
modules in the same directory, as found in gnu/dist.

A few symlinks were pointing to a nonexistent file named '(null)'
instead of their intended target. This was only seen when using the
arm_sdimage.sh script.
There is two ways of specifying links and directories. the first one
using an entry in one of the mtree files, and the second one in
/etc/Makefile.
Those entries where doubled, and one of them would specify some rights,
while the other had the target.
By removing those entries, I make sure there is only one definition of
these symlinks, which solves the problem I was seeing on an ARM image.
These symlinks are still present on a generated system, as they are
required.

Install /home/ast and /home/bin as part of the system build procedure,
as the setup script is not ran on the arm image.
/home/bin is needed for successful completion of our test suite.
This patch does not change the setup script, as it is not bothered by
those files/directiories being already there, and may be useful during
reinstallation on intel systems.

The tested targets are the followgin ones:
* tools
* distribution
* sets
* release
The remaining NetBSD targets have not been disabled nor tested
*at all*. Try them at your own risk, they may reboot the earth.
For all compliant Makefiles, objects and generated files are put in
MAKEOBJDIR, which means you can now keep objects between two branch
switching. Same for DESTDIR, please refer to build.sh options.
Regarding new or modifications of Makefiles a few things:
* Read share/mk/bsd.README
* If you add a subdirectory, add a Makefile in it, and have it called
by the parent through the SUBDIR variable.
* Do not add arbitrary inclusion which crosses to another branch of
the hierarchy; If you can't do without it, put a comment on why.
If possible, do not use inclusion at all.
* Use as much as possible the infrastructure, it is here to make
life easier, do not fight it.
Sets and package are now used to track files.
We have one set called "minix", composed of one package called "minix-sys"
Bumping libc files for unsupported architectures, to simplify merging.
A bunch of small fixes:
* in libutil update
* the macro in endian.h
* some undefined types due to clear separation from host.
* Fix a warning for cdbr.c
Some modification which were required for the new build system:
* inclusion path for const.h in sconst, still hacky
* Removed default malloc.c which conflicts on some occasions.
building defaults to off until clang is updated.
current clang does not handle -shared, necessary to change the ld
invocation to build shared libraries properly. a new clang should be
installed and MKPIC defaults to no unless the newer clang is detected.
changes:
. mainly small imports of a Makefile or two and small fixes
(turning things back on that were turned off in Makefiles)
. e.g.: dynamic librefuse now depends on dynamic
libpuffs, so libpuffs has to be built dynamically too
and a make dependency barrier is needed in lib/Makefile
. all library objects now have a PIC (for .so) and non-PIC
version, so everything is built twice.
. generate PIC versions of the compat (un-RENAMEd) jump files,
include function type annotation in generated assembly
. build progs with -static by default for now
. also build ld.elf_so
. also import NetBSD ldd
