- sendmsg: the accumulation of multiple in-flight file descriptors was
already described in the comments; now the code actually does what
the comments say :) -- also, added robustness in case of a failure;
- recvmsg: only create a socket rights message if there are file
descriptors pending at all;
- recvmsg: copy back the control message length;
- recvmsg: use CMSG_SPACE instead of CMSG_LEN to compute sizes.
Not sure if all of this is now working according to specification,
but at least tmux seems to be happy with it.

Well, make a start, anyway. Our copy was missing a legacy field from
the structure, that could very well cause applications to fail trying
to set, clear, or check it. As a consequence, SUN_LEN now yields the
same result as on NetBSD.

- move VFS calls to a separate source file;
- solve a few subtle bugs, mostly in error handling;
- simplify debug reporting code;
- make a few definitions more independent;
- restyle to something closer to KNF.

- remove non-PCI support, since all supported platforms with at_wini
devices also have PCI support by now;
- correspondingly, stop using information from the BIOS altogether;
- limit each driver instance to one controller, to be in line with
the general MINIX3 one-instance-per-controller driver model; this
limits the number of disks per at_wini instance to four;
- go through the controllers by the order of their occurrence in the
PCI table, thus removing the exception for compatibility devices;
- let the second at_wini instance shut down silently if there is only
one IDE controller;
- clean up some extra code we don't need anymore, and resolve some
WARNS=5 level warnings.
Overall, these changes should simplify automatic loading of the right
disk drivers at boot time in the future.

- change "vid/did" to "vid:did", old form still supported for now;
- allow "vid:did/subvid:subdid" specification in system.conf, in
which case a device will be visible to a driver if the subsystem
VID/DID also match.

GCC embeddeds in a string the configuration used when building itself,
this patches just updates that string to match the configuration
actually used.

* /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.

As the situation is right now, importing one of the commands the
script replaces, requires a doc/UPDATING step.
By moving the script to a shared folder, and symlinking it once per
command, this allows for separatly installed files on the system,
instead of one file being symlinked multiple times.

Now that the keymaps can distinguish between the regular slash key
and the slash key on the numeric keypad, we can avoid localization
of the latter.

This commit separates the low-level keyboard driver from TTY, putting
it in a separate driver (PCKBD). The commit also separates management
of raw input devices from TTY, and puts it in a separate server
(INPUT). All keyboard and mouse input from hardware is sent by drivers
to the INPUT server, which either sends it to a process that has
opened a raw input device, or otherwise forwards it to TTY for
standard processing.
Design by Dirk Vogt. Prototype by Uli Kastlunger.
Additional changes made to the prototype:
- the event communication is now based on USB HID codes; all input
drivers have to use USB codes to describe events;
- all TTY keymaps have been converted to USB format, with the effect
that a single keymap covers all keys; there is no (static) escaped
keymap anymore;
- further keymap tweaks now allow remapping of literally all keys;
- input device renumbering and protocol rewrite;
- INPUT server rewrite, with added support for cancel and select;
- PCKBD reimplementation, including PC/AT-to-USB translation;
- support for manipulating keyboard LEDs has been added;
- keyboard and mouse multiplexer devices have been added to INPUT,
primarily so that an X server need only open two devices;
- a new "libinputdriver" library abstracts away protocol details from
input drivers, and should be used by all future input drivers;
- both INPUT and PCKBD can be restarted;
- TTY is now scheduled by KERNEL, so that it won't be punished for
running a lot; without this, simply running "yes" on the console
kills the system;
- the KIOCBELL IOCTL has been moved to /dev/console;
- support for the SCANCODES termios setting has been removed;
- obsolete keymap compression has been removed;
- the obsolete Olivetti M24 keymap has been removed.

Due to the existence of /dev/console and /dev/log, and the new
"console=" setting, it is now possible that a single non-PTY object
(e.g. serial) is accessible through two different minor numbers. This
poses a problem when sending late select replies (CDEV_SEL2_REPLY),
because the object's minor number can not be used to identify the
device. Since selecting on such objects through translated minor
numbers is actually required, we now save the minor number used to
initiate the select query in order to send a late reply.
The solution is suboptimal, as it is not possible to use two different
minors to select on the same object at once. In the future, there
should be at least one select record for each minor that can be used
with each object.

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().

* Renamed struct timer to struct minix_timer
* Renamed timer_t to minix_timer_t
* Ensured all the code uses the minix_timer_t typedef

* Resolved prototype conflict by renaming kernel's (re)set_timer
to (re)set_kernel_timer.

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).
Change-Id: I0b72312e79992b9818559c6546a0e52cd95184c2
- 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.
Change-Id: I45c818f817c11d90c5f94ae26a2fc49e36e6761e
- 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;

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.
