74711a3b14 Check if kernel calls is allowed (from process' call mask) added. Not yet 
enforced. If a call is denied, this will be kprinted. Please report any such
errors, so that I can adjust the mask before returning errors instead of
warnings.

Wrote CMOS driver. All CMOS code from FS has been removed. Currently the
driver only supports get time calls. Set time is left out as an exercise
for the book readers ... startup scripts were updated because the CMOS driver
is needed early on. (IS got same treatment.) Don't forget to run MAKEDEV cmos
in /dev/, otherwise the driver cannot be loaded.

b69ca94efb Fixed 'bug' in log driver that caused kernel messages not to be displayed. 
This was caused by a change in the shared driver code. Not log's fault.

Renamed #definitions of driver process numbers, e.g., TTY now is TTY_PROC_NR.
All known (special) processes now have consistent naming scheme. Kernel tasks
don't follow this scheme.

904cf1f84d A "fix" for bug no. 2 is to check if the process slot has disappeared. 
Not a really good solution (as it might not catch situations in which this
is caused by another bug), but the forrest of checks necessary might be worse
than this quick fix - because when looking for the cause, I found some other
cases in which the PM would panic as well. See info in bug 2 for details.

Another fix is to delay notification of PM by SYSTASK of signals delivered
internally until after the reply (e.g. of exec()), because the reply would
be messed up otherwise (receiving the notify instead of reply). This caused
SIGTRAP not to be delivered properly with traced processes.

45ddea1cdd Fixed bug that caused the PM to brutalize the contents of the 'memory' 
variable. Parsing worked, but future requests for the variable (such as
by the sysenv command) returned truncated data. This caused the system
(e.g. setup script) to think the amount of memory was tiny, and caused
the enabling of swapspace, while it is unnecessary.

d844d2a547 Fixed nasty bug that would cause FS to loop forever in rw_scattered (while 
syncing, for instance) if blocks are unwritable. This could happen if:

  . write goes beyond device boundary to a block device
  . write is done for a complete block or more; thus the
    block is not retrieved first (at which point it would be noticed
    it doesn't exist), but the buffer is simply allocated
  . at write time, the device i/o doesn't succeed, but rw_scattered
    doesn't understand this and loops forever trying to get the block
    written.

Currently, if no blocks can be written, the loop aborts, leaving all
buffers intact but potentially dirty. When invalidate() is called on the
device, the buffers will disappear (even if dirty). Same story for if
the buffer is removed due to rmed from lru chain. There's not much we
can do about this, however - we can't keep these blocks around, forever
occupying a buffer in the buffer cache.

The second part of the solution is not to let unwritable buffers be
created in the first place. How to do this, however, without doing a
wasteful read first?

It looks like this code was in 2.0.4 too.

9664ba0c4f Started select() implementation.

f2a85e58d9 Various updates. 
* Removed some variants of the SYS_GETINFO calls from the kernel;
  replaced them with new PM and utils libary functionality. Fixed
  bugs in utils library that used old get_kenv() variant.
* Implemented a buffer in the kernel to gather random data.
  Memory driver periodically checks this for /dev/random.
  A better random algorithm can now be implemented in the driver.
  Removed SYS_RANDOM; the SYS_GETINFO call is used instead.
* Remove SYS_KMALLOC from the kernel. Memory allocation can now
  be done at the process manager with new 'other' library functions.

d0b5cf84cb Undid usage of vector-copy function. It's a good idea but there's a bug 
there somewhere. I'll debug first, then recommit.

6d23f072f3 Cleaned up src/lib/utils library. Renamed server_ functions to more logical 
names. All system processes can now either use panic() or report() from
libutils, or redefine their own function. Assertions are done via the standard
<assert.h> functionality.

447b988154 exec now uses phys_zero system call to zero bss segments (instead of 
using phys_copy to copy zeroes there for every kb), which is a big
optimisation in some cases

0165662cd9 Replaced flagalrm() timers with another technique to check for timeouts. 
This allowed removing the p_flagarlm timer from the kernel's process table.
Furthermore, I merged p_syncalrm and p_signalrm into p_alarm_timer to save
even more space. Note that processes can no longer have both a signal and
synchronous alarm timer outstanding as of now.

accounting from kernel (now in PM).  Large amount of files in this commit
is due to system time problems during development.

ccd17ecfed New NOTIFY system call! Queued at kernel. Duplicate messages (with same source 
and type) are overwritten with newer flags/ arguments. The interface from
within the kernel is lock_notify(). User processes can make a system call with
notify(). NOTIFY fully replaces the old notification mechanism.

307c825515 New NOTIFY trap (IPC call) to send queued notification messages. 
The call works. Permission check, restriction of outstanding notifications
to be added. Low level code to make it work from within interrupt handlers
will be added as well.
