be30a639cd Don't sys_kill SELF if a PM exit fails; just generate a fault to get
us killed through the kernel with PM finding out.

This makes it unnecessary for servers and drivers to be able to do
sys_kill generally, so KILL can go out of /etc/drivers.conf.

168d766f32 . pci driver now returns devices, even when they have been pci_reserve()d
. pci_reserve() returns an error on devices that have already been reserved,
  instead of panic()ing; the pci_reserve() library call still panics,
  pci_reserve_ok() returns an int.
. this allows at_wini to use the instance value as intended, as all devices
  are seen, even reserved ones
. only devices actually used by at_wini are pci_reserve()d
. pci doesn't release devices based on argv[0], as at_wini both have the
  same name and multiple instances won't work together properly

3275602598 . made memory parsing function into a library call
(moved 'struct memory' to <minix/type.h> for this library call)
 . removed some debugging messages from pci library

2194bc0310 vfs/mount/rs/service changes:
. changed umount() and mount() to call 'service', so that it can include
   a custom label, so that umount() works again (RS slot gets freed now).
   merged umount() and mount() into one file to encode keep this label
   knowledge in one file.
 . removed obsolete RS_PID field and RS_RESCUE rescue command
 . added label to RS_START struct
 . vfs no longer does kill of fs process on unmount (which was failing
   due to RS_PID request not working)
 . don't assume that if error wasn't one of three errors, that no error
   occured in vfs/request.c
mfs changes:
 . added checks to copy statements to truncate copies at buffer sizes
   (left in debug code for now)
 . added checks for null-terminatedness, if less than NAME_MAX was copied
 . added checks for copy function success
is changes: 
 . dump rs label
drivers.conf changes:
 . added acl for mfs so that mfs can be started with 'service start',
   so that a custom label can be provided

6f77685609 Split of architecture-dependent and -independent functions for i386,
mainly in the kernel and headers. This split based on work by
Ingmar Alting <iaalting@cs.vu.nl> done for his Minix PowerPC architecture
port.

 . kernel does not program the interrupt controller directly, do any
   other architecture-dependent operations, or contain assembly any more,
   but uses architecture-dependent functions in arch/$(ARCH)/.
 . architecture-dependent constants and types defined in arch/$(ARCH)/include.
 . <ibm/portio.h> moved to <minix/portio.h>, as they have become, for now,
   architecture-independent functions.
 . int86, sdevio, readbios, and iopenable are now i386-specific kernel calls
   and live in arch/i386/do_* now.
 . i386 arch now supports even less 86 code; e.g. mpx86.s and klib86.s have
   gone, and 'machine.protected' is gone (and always taken to be 1 in i386).
   If 86 support is to return, it should be a new architecture.
 . prototypes for the architecture-dependent functions defined in
   kernel/arch/$(ARCH)/*.c but used in kernel/ are in kernel/proto.h
 . /etc/make.conf included in makefiles and shell scripts that need to
   know the building architecture; it defines ARCH=<arch>, currently only
   i386.
 . some basic per-architecture build support outside of the kernel (lib)
 . in clock.c, only dequeue a process if it was ready
 . fixes for new include files

files deleted:
 . mpx/klib.s - only for choosing between mpx/klib86 and -386
 . klib86.s - only for 86

i386-specific files files moved (or arch-dependent stuff moved) to arch/i386/:
 . mpx386.s (entry point)
 . klib386.s
 . sconst.h
 . exception.c
 . protect.c
 . protect.h
 . i8269.c

3512a86b44 . DS understands publishing and subscribing where keys are in string
form. Subscriptions are regular expressions.
 . different types are stored per key; currently u32 and/or string.
   the same key can be referenced (publish, subscribe, check) as any type.
 . notify()s are sent when subscriptions are triggered (publishing or
   updating of matching keys); optionally, a subscribe flag sends
   updates for all matching keys at subscription time, instead of only
   after updates after subscribing
 . all interfacing to ds is in /usr/src/lib/syslib/ds.c.
 . subscribe is ds_subscribe
   publish functions are ds_publish_<type>
   retrieve functions are ds_retrieve_<type> (one-time retrieval of a value)
   check functions are ds_check_<type> (check for updated key caller
      subscribes to not yet checked for, or ESRCH for none)
 . ramdisk driver updated with new ds interface

a587273c56 . expanded grant manipulation interface to more direct
manipulation
. made fs allocate a grant for every ioctl, even if no data
  is being copied, in order to disambiguate concurrent ioctls
  on the same minor

9df1183b94 . removed const from putenv() for g++
. added safecopies.c:
  these are library functions to maintain grant tables in own address space
. sys_safecopy.c:
  interfaces to kernel calls to perform safe copy functions in from or to
  foreign process
. changes in i/o fields (type merged with request) reflected in
  library functions (sys_out.c, sys_vinb.c, sys_vinl.c, sys_vinw.c,
  sys_voutb.c, sys_voutl.c, sys_voutw.c)
. type merged with request in sys_sdevio, also now accepts offset which
  is used when a grant is specified (the _DIO_SAFE subtype)
. system printf() function changed to send DIAGNOSTICS_S messages, which
  specify a grant id instead of a direct address for the buffer to be
  printed; tty and log can then safecopy the buffer

3ea083b8d4 Actually remove allocmem and freemem sources from the library. 2006-05-19 12:45:55 +00:00
Philip Homburg
e9aabcf2f8 Disabled building rescue driver (no longer needed). Moved allocmem from
library to the memory driver. Always put output from within TTY directly on
the console. Removed second include of driver.h from tty.c. Made tty_inrepcode
bigger. First step to move PM and FS calls that are not regular (API)
system calls out of callnr.h (renumbered them, and removed them from the
table.c files). Imported the Minix-vmd uname implementation. This provides
a more stable ABI than the current implementation. Added a bit of security
checking. Unfortunately not nearly enough to get a secure system. Fixed a
bug related to the sizes of the programs in the image (in PM patch_mem_chunks).
