sysroot support was enabled only for cross versions of the binutils
tools.
This patch also activate it for the native tools which are installed
on the target system.

Most systems provide the full version number in the
'release' field and the kernel version in 'version'.
Minix used to split the full version number between
release and version which caused problems for pkgsrc
and other applications. This patch brings Minix's
uname in line with other systems such as NetBSD.
It also brings the getty banner in line with NetBSD.
Old Minix uname:
sysname->Minix
nodename->10.0.2.15
release->3
version->2.1
machine->i686
New Minix uname:
sysname->Minix
nodename->10.0.2.15
release->3.2.1
version->Minix 3.2.1 (GENERIC)
machine->i686

The set of processes to which a SIGKMESS signal is sent whenever new
diagnostics messages are added to the kernel's message buffer, is now
no longer hardcoded. Instead, processes can (un)register themselves
to receive such notifications, by means of sys_diagctl().

The tool has been changed heavily to match our VND driver model.
NetBSD is in the process of renaming it from vnconfig(8) to
vndconfig(8). To keep things in sync, we have to play along.

This call copies a file descriptor from a remote process into the
calling process. The call is for the VND driver only, and in the
future, ACLs will prevent any other process from using this call.

When installed, the test scripts lose their ".sh" suffix, causing them
to be skipped by the "run" script. With this patch, the tests are no
longer specified with ".sh" suffix in the run script, and the suffix
is added automatically as necessary.
LSC: Minor adaptation to keep track of history. As this patch has been
forward ported into mainline, a simple rebase would loose this
commit (cf commit 1f317d315c).

- 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.

- include all ioctl subheaders, properly listing all letters;
- change FBD's ioctl calls to use 'B' instead of 'F', in
preparation of the VND driver.

Not all services involved in block I/O go through VM to access the
blocks they need. As a result, the blocks in VM may become stale,
possibly causing corruption when the stale copy is restored by a
service that does go through VM later on. This patch restores support
for forgetting cached blocks that belong to a particular device, and
makes the relevant file systems use this functionality 1) when
requested by VFS through REQ_FLUSH, and 2) upon unmount.

Previously, VFS would reopen a character device after a driver crash
if the associated file descriptor was opened with the O_REOPEN flag.
This patch removes support for this feature. The code was complex,
full of uncovered corner cases, and hard to test. Moreover, it did not
actually hide the crash from user applications: they would get an
error code to indicate that something went wrong, and have to decide
based on the nature of the underlying device how to continue.
- remove support for O_REOPEN, and make playwave(1) reopen its device;
- remove support for the DEV_REOPEN protocol message;
- remove all code in VFS related to reopening character devices;
- no longer change VFS filp reference count and FD bitmap upon filp
invalidation; instead, make get_filp* fail all calls on invalidated
FDs except when obtained with the locktype VNODE_OPCL which is used
by close_fd only;
- remove the VFS fproc file descriptor bitmap entirely, returning to
the situation that a FD is in use if its slot points to a filp; use
FILP_CLOSED as single means of marking a filp as invalidated.
Change-Id: I34f6bc69a036b3a8fc667c1f80435ff3af56558f
- block the calling thread on character device close;
- fully separate block and character open/close routines;
- reuse generic open/close code for the cloning case;
- zero all messages to drivers before filling them;
- use appropriate types for major/minor device numbers.
Change-Id: Ia90e6fe5688f212f835c5ee1bfca831cb249cf51
- prefix them with VFS_ as they are going to VFS;
- give these calls normal call numbers;
- give them their own set of message field aliases;
- also make do_mapdriver a regular call.

The B0-B115200 defines are flags, and not the actual speed they
represent.
This fixes an incoherency for B0 handling, and documents why it is
required to call the function again after changing the speed flag.
DFL_BAUD is set to one of the flag, so to translate it to an actual
speed, the function calls itself again, which will always be able to
finish without inducing another recursive call.

It is unclear why /dev/log has its own open/close rules, but those
rules conflict with serial console redirection. This does not solve
the root of the problem, but it puts back in place more or less the
same workaround that was already in place before the TTY overhaul.
Change-Id: Ib53abbc28a76c1f2b0befc8448aeed0173bc96a5
- writing to a PTY master side blocks if there is not already a
blocked reader on the slave side, and select now reflects this;
- internally, TTY now uses a test based on "caller != NONE" rather
than "grant != GRANT_INVALID" to identify whether a call is
currently ongoing;
- "offset" fields have been removed as they equal the corresponding
"cum" fields;
- improved variable typing and function naming here and there;
- various other small fixes.
Change-Id: I6b51452888942e864b4e034e8c8490576184a23e
- check each file descriptor's open access mode (filp_mode);
- treat an error returned by a character driver as a select error;
- check all filps in each set before finishing select;
- do not copy back file descriptor sets if an error occurred;
- remove the hardcoded list of supported character major devices,
since all drivers should now be capable of responding properly;
- add tests to test40 and fix its error count aggregation.
Change-Id: I57ef58d3afb82640fc50b59c859ee4b25f02db17
- simplify and repair UDS request handling state machine;

The new API now covers the entire character driver protocol, while
hiding all the message details. It should therefore be used by all
new character drivers. All existing drivers that already made use of
libchardriver have been changed to use the new API.
As one of the most important API changes, support for scatter and
gather transfers has been removed, as several key drivers already
did not support this, and it could be supported at the safecopy
level instead (for a future readv/writev).
Additional changes include:
- respond to block device open requests to avoid hanging VFS threads;
- add support for sef_cancel.

Some block drivers do not impose any alignment requirements, and this
patch allows such block drivers to pass the test set. As a side effect,
minimal support for min_write is added, but this part of blocktest is
in need of further improvement.

If a device node is given without path, and opening the node fails
initially, prepend "/dev/" to the node name and try opening again.
This is more in line with NetBSD behavior.

The block driver protocol and libblockdriver's bdr_ioctl hook are
changed, as well as the users of this hook. Other parts of the system
are expected to change accordingly eventually, since the ioctl(2)
prototype has been aligned with NetBSD's.
Change-Id: Ide46245b22cfa89ed267a38088fb0ab7696eba92
I/O control requests now come with the endpoint of the user process
that initiated the ioctl(2) call. It is stored in a new BDEV_USER
field, which is an alias for BDEV_FLAGS. The contents of this field
are to be used only in highly specific situations. It should be
preserved (not replaced!) by services that forward IOCTL requests,
and may be set to NONE for service-initiated IOCTL requests.

The original R_BIT and W_BIT definitions have nothing to do with the
way these bits are used. Their distinct usage is more apparent when
they have different names.

Previously, reading from or writing to a character device would not
update the file position on the corresponding filp object. Performing
this update correctly is not trivial: during and after the I/O
operation, the filp object must not be locked. Ideally, read/write
requests on a filp that is already involved in a read/write operation,
should be queued. For now, we optimistically update the file position
at the start of the I/O; this works under the assumptions listed in
the corresponding comment.

Previously it would use bits of the character driver protocol, which
will change heavily. In the new situation, the BUSC_I2C_xxx requests
use a protocol more in line with the PCI protocol, with the reply code
in m_type.

Opening and closing the master side of a pseudo terminal without
opening the slave side would result in the pseudo terminal becoming
permanently unavailable. In addition, reopening the slave side
would be possible but not allow for I/O. Finally, attempting to
open an in-use master would wipe its I/O state. These issues have
been resolved.

POSIX states that when interrupted, partially successful pipe
operations should return the partial result rather than EINTR. VFS
previously wouldn't look at the partial result, and not clear it
either, which would result in a panic upon the next pipe operation.
