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.

f9ccfca2a1 (Incomplete) support for access control in PCI (pci_set_acl).
-script argument to service for crash recovery scripts
-config argument to service for driver resource configuration
restart command in service to restart a driver after a crash (for use in
crash recovery scripts).
down and refresh now take labels instead of pids.
verious changes in rs to make this work.

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

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.

3b814d36d1 Rename paramctl to setgrant. 2006-06-23 15:35:05 +00:00

002922fa4c New kernel call, SYS_PARAMCTL, that sets parameters of the caller
and is therefore unprivileged. Used to set grant tables.

31318a8ce5 library interface for vectored safecopy variant. 2006-06-23 11:54:35 +00:00
Ben Gras
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.
