Diagnostics messages are printed using locally generated requests,
using KERNEL as the calling endpoint. No reply should be sent for
such cases. This check was accidentally lost with the previous
removal of tty_reply().

- 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)
get getservbyport() out of the inner loop

- Defining CLOCKS_PER_SEC = 100, instead of 60.
This define is here for legacy reasons, use sysconf(_SC_CLK_TCK) to
retrieve the actual number of clock tick per second of the system in
new code.
- Moving stime prototype to minix/sysutil.h

Also removing lseek64, pread64, pwrite64.
Those functions have lost their "raison d'être", when off_t switched to
64bits.

This allows us to write things like this:
message m;
m.m_notify.interrupts = new_value;
or
message *mp;
mp->m_notify.interrupts = new_value;
The shorthands macro have been adapted for the new scheme, and will be
kept as long as we have generic messages being used.

doesn't exist anymore
. various related test expansions, improvements, fixes

* Also change _orig to _intr for clarity
* Cleaned up {IPC,KER}VEC
* Renamed _minix_kernel_info_struct to get_minix_kerninfo
* Merged _senda.S into _ipc.S
* Moved into separate files get_minix_kerninfo and _do_kernel_call
* Adapted do_kernel_call to follow same _ convention as ipc functions

- move system calls for use by services from libminlib into libsys;
- move srv_fork(2) and srv_kill(2) from RS and into libsys;
- replace getprocnr(2) with sef_self(3);
- rename previous getnprocnr(2) to getprocnr(2);
- clean up getepinfo(2);
- change all libsys calls that used _syscall to use _taskcall, so as
to avoid going through errno to pass errors; this is already how
most calls work anyway, and many of the calls previously using
_syscall were already assumed to return the actual error;
- initialize request messages to zero, for future compatibility
(note that this does not include PCI calls, which are in need of a
much bigger overhaul, nor kernel calls);
- clean up more of dead DS code as a side effect.

This single function allows copying file descriptors from and to
processes, and closing a previously copied remote file descriptor.
This function replaces the five FD-related UDS backcalls. While it
limits the total number of in-flight file descriptors to OPEN_MAX,
this change greatly improves crash recovery support of UDS, since all
in-flight file descriptors will be closed instead of keeping them
open indefinitely (causing VFS to crash on system shutdown). With the
new copyfd call, UDS becomes simpler, and the concept of filps is no
longer exposed outside of VFS.
This patch also moves the checkperms(2) stub into libminlib, thus
fully abstracting away message details of VFS communication from UDS.

- 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.

- 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.
Change-Id: I7b0537adfccac8b92b5cc3e78dac9f5ce3c79f03
- 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-Id: Ia64d08cfbeb9916abd68c9c2941baeb87d02a806
- 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.

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.

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().

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