c2ffe723d1 - Moved (u)mount prototypes from unistd.h to sys/mount.h.
- Prepared mount system call to accept multiple mount flags
   instead of just read_only (however, it remains backwards
   compatible).
 - Updated the man mount(2) to reflect new header file usage. 
 - Updated badblocks, newroot, mount, and umount commands to use the
   new header file.

dac531addf Support for VMWare Workstation 6.x
VMWare Workstation 6.x would previously die when running MINIX 3 with an
IOSPACE assertion and several error messages about multiply registered
I/O ports. The assertion is triggered when we probe for BAR sizes in
record_bar(). The solution: The PCI driver now disables I/O and mem
access before probing for BAR sizes.

Bumped up NR_PCIDEV and NR_PCIBUS, since Workstation 6.x virtualizes
more PCI buses and devices.

bdab3c4cfb Library call for cpu features; make kernel and vm use this to query cpu
features (specifically: 4MB pages and TLB global bit).  Only enable
these features in CR4 if available. 4MB pages to be used in the near
future.

fe8c612aa4 support in 'mount' for specifying file system type and options 2009-05-13 15:39:44 +00:00
Ben Gras
dd56aa321f to let tty run with its own page table (instead of with the kernel identity
map table), make it map in video memory.

sadly, this breaks tty in non-paged mode.

happily, this simplifies the code by throwing out the messing
around with segments, and throws out vidcopy.s.

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).

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.

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

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

b01aff70d2 use servers/inet/mq.[ch] to queue messages using mq_queue() in
libdriver.  at_wini now queues messages it can't handle it receives when
waiting for an interrupt. this way it can do receive(ANY) and timeouts
should be working again (were broken for VFS, as with the advent of VFS,
at_wini could get requests from a filesystem while it was waiting for an
interrupt - as a hack, the receive() was changed to receive(HARDWARE)).

Added mq.c to libdriver, and made libdriver an actual library that
drivers link with -L../libdriver -ldriver. (So adding files, if
necessary, is easier next time.)

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

82173212ee Introduction of a 'big' ioctl, with more bits (20) reserved for encoding the
size field. The TIOCSFON ioctl size (8192) didn't get encoded properly,
as there weren't enough bits for it (12) in the regular format.

The new format has only one type field, and an extra flag (_IOC_BIG)
turned on. FS checks for this flag and uses the alternative decoding
of the ioctl codes to determine the size when doing grants.

This unbreaks loadfont, although that still uses a phys copy in tty.

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

04b478f177 More stack for tcpd.
Safecopies renders the NWIOQUERYPARAM ioctl useless. This functionality
is now replaced with /dev/ipstat. Write the request to the device and
read the answer in one read request.

d7174ec0ab Added SI_CALL_STATS and ENABLE_SYSCALL_STATS for system call statistics.
Added BUSC_PCI_DEV_NAME_S and BUSC_PCI_SLOT_NAME_S to support safecopies in PCI.
Added DL_WRITEV_S, DL_READV_S, DL_GETSTAT_S, DL_GRANT, and iovec_s_t to support
safecopies in ethernet drviers. Renamed DL_INIT to DL_CONF, and DL_INIT_REPLY
to DL_CONF_REPLY.
Added SYS_READBIOS and sys_readbios to read from BIOS data areas.
Added GET_KMESS_S for safecopy support in LOG.
Added sys_safe_insb and sys_safe_outsb.

cfb984e9bd . renamed __str to __makestr to allow for g++
. changed some CMOS ioctl codes to have correct sizes (struct tm instead
  of u32_t), a disk ioctl code from W to RW, and memory ioctl codes from R
  to W, needed for proper matching of grant in FS
2006-06-20 08:40:26 +00:00

aaca17c36d . introduced DEV_READ_S, DEV_WRITE_S, DEV_SCATTER_S, DEV_GATHER_S
and DEV_IOCTL_S as replacements for DEV_READ, DEV_WRITE, DEV_SCATTER,
  DEV_GATHER and DEV_IOCTL. Instead of a direct address, the *_S commands
  pass 'grant ids' to the drivers which are referenced through a new set
  of copy calls (sys_safecopyfrom and sys_safecopyto). in order for this
  copy to succeed, the grant must have previously been created in the
  address space of the granter.
. bitmap manipulation functions moved to <minix/bitmap.h>
. HIGHPOS introduced as field containing high 32 bits of position in
  device I/O message; TTY_FLAGS no longer used
. IO_GRANT field introduced for GRANTs, to replace ADDRESS
. REP_IO_GRANT field for un-SUSPEND messages introduced to indicate
  grant for which I/O was done to disambiguate messages
. SYS_SAFECOPYFROM and SYS_SAFECOPYTO introduced as new calls
. SYS_PRIV_SET_GRANTS code introduced as a code to set the address and
  size of the grant table in a process' own address space
. 'type' and 'direction' field of _ins* and _outs* I/O functions
  are merged into one by ORing _DIO_INPUT/_DIO_OUTPUT and _DIO_BYTE/_DIO_WORD
  etc. This allows for an additional parameter, _DIO_SAFE, which indicates
  the address in another address space isn't actually an address, but
  a grant id. Also needs an offset, for which fields had to be merged.
. SCP_* are field names for SYS_SAFECOPY* functions
. DIAGNOSTICS and GET_KMESS moved to their own range above DIAG_BASE,
  added DIAGNOSTICS_S which is a grant-based variant of DIAGNOSTICS
. removed obsolete BINCOMPAT and SRCCOMPAT options
. added GRANT_SEG type for use in vircopy - allows copying to a grant
  id (without offset)
. added _MINIX_IOCTL_* macros that decode information encoded by
  _IO* macros in ioctl codes, used to check which grants are necessary
  for an ioctl
. introduced the type endpoint_t for process endpoints, changed some
  prototypes and struct field types to match
. renamed protected to prot for g++

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).
