9a01c828c8 VFS-FS error codes: better safe than sorry 2009-05-11 11:30:04 +00:00
David van Moolenbroek
0ac1aaccca Limited support for nested FS->VFS requests during VFS->FS call. 
- Changed VFS-FS protocol to only store OK or negative error code in
  m_type field of reply messages.
- Changed VFS to treat nonzero positive replies from FS as requests.
- Added backwards compatibility to VFS and MFS.
No protection of global data structures is provided in VFS, so many
VFS calls cannot be made safely by FS servers during many FS calls.
Use with caution (or, preferably, not at all).

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.

c628f24bc2 moved stacktrace to sysctl, as vmctl is very privileged so can't 
be used outside VM. IS code cleanup. added stacktrace feature to IS.

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.
