a2485b346c potential buffer overruns in env_* routines 2009-05-10 16:54:37 +00:00
Ben Gras
9647fbc94e moved type and constants for random data to include file;
added consistency check in random; added source of randomness
internal to random using timing; only retrieve random bins that are full.

3cc092ff06 . new kernel call sysctl for generic unprivileged system operations;
now used for printing diagnostic messages through the kernel message
   buffer. this lets processes print diagnostics without sending messages
   to tty and log directly, simplifying the message protocol a lot and
   reducing difficulties with deadlocks and other situations in which
   diagnostics are blackholed (e.g. grants don't work). this makes
   DIAGNOSTICS(_S), ASYN_DIAGNOSTICS and DIAG_REPL obsolete, although tty
   and log still accept the codes for 'old' binaries. This also simplifies
   diagnostics in several servers and drivers - only tty needs its own
   kputc() now.
 . simplifications in vfs, and some effort to get the vnode references
   right (consistent) even during shutdown. m_mounted_on is now NULL
   for root filesystems (!) (the original and new root), a less awkward
   special case than 'm_mounted_on == m_root_node'. root now has exactly
   one reference, to root, if no files are open, just like all other
   filesystems. m_driver_e is unused.

03446f5554 micro_delay in sysutil, used in ti1225, dp8390, fxp and
orinoco now. Uses a combination of tickdelay (where possible) and
calibrated busywait (where necessary).

6d50591226 . let kernel use read_tsc() from sysutil library
. read_tsc() in sysutil library saves edx and eax now
 . added read_tsc_64() by Antonio Mancina to load tsc into
   a 64-bit data type directly
 . deleted read_tsc.h in favour of a prototype in <minix/syslib.h>

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

73e5de6354 Added sys_readbios.
Changed pci_dev_name and pci_slot_name to use safecopies.
Mae it possible to disable the use of safecopies in kputc for debugging.

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

36e8c1a185 Added assert to syslib. Moved panic from sysutil to syslib for assert.
Panic now tries sys_kill with SIGKILL first.

ea75918df1 printf() by kernel and servers now send messages to an array of processes,
OUTPUT_PROCS_ARRAY in <minix/config.h>, in that order, terminated by NONE.
log no longer forwards messages to tty itself. This leads to less funny
loops and more robust debug-message handling. Also the list of
processes receiving messages can easily be changed around or disabled by
editing the array (e.g. disable it by changing the array to { NONE }.).

c79574aba4 A new panic that makes processes exit with PM knowing about it, instead
of sys_exit, so that PM functions (e.g. findproc) keep working properly,
and RS finds out about process deaths.

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.

fe0dcb5c00 AT driver is not modified (debugging only);
TTY: select and revive with new notify and FS call back;
kernel: removed old notify code; removed ugly prepare_shutdown timer
kputc: don't send to FS if PRINTF_PROC fails
