6d5a0a8c23 Various fixes:
1. imgp->image_header needs to be cleared for the bp == NULL && `goto
   interpret' case, else exec_fail_dealloc would free it twice after
   an error.

2. Moved the vp->v_writecount check in exec_check_permissions() to
   near the end.  This fixes execve("/dev/null", ...) returning the
   bogus errno ETXTBSY.  ETXTBSY is still returned for attempts to
   exec interpreted files that are open for writing.  The man page
   is very old and wrong here.  It says that ETXTBSY is for pure
   procedure (shared text) files that are open for writing or reading.

3. Moved the setuid disabling in exec_check_permissions() to the end.
   Cosmetic.  It's more natural to dispose of all the error cases
   first.

...plus a couple of other cosmetic changes.

5ea0ae111d When not using SCB paging, we can always directly index the SCB of interest
either by looking it up in the array of pending, per target, untagged
transactions, or by using the tag value passed in during the identify.  The
old code only direct indexed for tagged transactions.  This makes the
"findSCB" routine only necessary when SCB paging is enabled, so appropriately
conditionalize it.  This greatly simplifies the non SCB paging code flow.

b67cbc6548 Implement code for an OpenBSD-style issetuigid().
This is valueable for library code which needs to be able to find out
whether the current process is or *was* set[ug]id at some point in the
past, and may have a "tainted" execution environment.  This is especially
a problem with the trend to immediately revoke privs at startup and regain
them for critical sections.  One problem with this is that if a cracker
is able to compromise the program while it's still got a saved id, the
cracker can direct the program to regain the privs.  Another problem is
that the user may be able to affect the program in some other way (eg:
setting resolver host aliases) and the library code needs to know when it
should disable these sorts of features.

a08f4bf601 Fully implement the clause in Appendix B.4.2.2 from Posix 1003.1
that allows traditional BSD setuid/setgid behavior.

The only visible difference should be that a non-root setuid program
(eg: inn's "rnews" program) that is setuid to news, can completely
"become" uid news. (ie: setuid(geteuid())  This was allowed in
traditional 4.2/4.3BSD and is now "blessed" by Posix as a special
case of "appropriate privilige".

Also, be much more careful with the P_SUGID flag so that we can use it
for issetugid() - only set it if something changed.

8a5d815aa0 Make setgroups(0, xxx) behave as it does on SYSV, namely clear the groups
vector except for the egid in groups[0].  There is a risk that programs
that come from SYSV/Linux that expect this to work and don't check for
error returns may accidently pass root's groups on to child processes.

We now do what is least suprising (to non BSD programs/programmers) in
this scenario, and nothing is changed for programs written with BSD groups
rules in mind.

a91b87211d In accept1(), falloc() is called after the process has awoken, but prior
to removing the connection from the queue. The problem here is that
falloc() may block and this would allow another process to accept the
connection instead. If this happens to leave the queue empty, then the
system will panic with an "accept: nothing queued".

Also changed a wakeup() to a wakeup_one() to avoid the "thundering herd"
problem on new connections in Apache (or any other application that has
multiple processes blocked in accept() for the same socket).

6c14d95d0d Treat symlinks as first class citizens with their own uid/gid rather than
as shadows of their containing directory.  This should solve the problem
of users not being able to delete their symlinks from /tmp once and for
all.

Symlinks do not have modes though, they are accessable to everything that
can read the directory (as before).  They are made to show this fact at
lstat time (they appear as mode 0777 always, since that's how the the
lookup routines in the kernel treat them).

More commits will follow, eg: add a real lchown() syscall and man pages.

00780cef44 Define our own version of DIRBLKSIZ instead of (ab)using ufs's value.
Use the same value of 512 (ufs actually uses DEV_BSIZE).  There are
too many versions of DIRBLKSIZ, one for ufs, one for ext2fs, one for
nfs, one for ibcs2, one for linux, one for applications, ... I think
nfs's DIRBLKSIZ needs to be a divisor of the directory blocks sizes
of all supported file systems.  There is also NFS_DIRBLKSIZ, which is
different from nfs's DIRBLKSIZ but is sometimes confused with it in
comments.

Removed a bogus #ifdef KERNEL that hid the tunable constants for nfs.
This came in undocumented with the Lite2 merge although it isn't in
Lite2.  It required more-bogus #define KERNEL's in fstat and pstat
to make the constants visible.

Restored a spelling fix from rev.1.17.

31774f6d83 Interim patch/kludge for keyboard lock-up when `kbdcontrol' tries to
change typematic rate, or the X server (XFree86 or Accelerated X)
starts up.

So far, there have been two independent reports from Dell Latitude XPi
notebook/laptop owners. The Latitude seems to be the only system which
suffers from this problem.  (I don't know the problem is with the
entire Latitude line or with only some Latitude models) No problem
report has been heard about other systems (I certainly cannot
reproduce the problem in my -current and 2.2 systems).

In 3.0-CURRENT, 2.2-RELEASE and 2.2-GAMMA-970310, when programming the
keyboard LED/repeat-rate, `set_keyboard()' in `syscons' tells the
keyboard controller not to generate keyboard interrupt (IRQ1) and then
enable tty interrupts, expecting the keyboard interrupt doesn't occur.

It appears that somehow Latitude's keyboard controller still generates
the keyboard interrupt thereafter, and `set_keyboard()' doesn't see
the return code from the keyboard because it is consumed by the
keyboard interrupt handler.

The patch entirely disables tty interrupts while setting LED and
typematic rate in `set_keyboard()', making the routine behave more
like the previous versions of `syscons' (versions in 2.1.X and
2.2-ALPHA, -BETA, and some -GAMMAs). The reporter said this patch
eliminated the problem.

(I also found another typo/bug, but the reporter and I found that it
wasn't the cause of the problem...)

This should go into RELENG_2_2.

e4602ad9e5 Don't include <sys/ioctl.h> in the kernel. Stage 10 (final). Warn if
<sys/ioctl.h> is included in the kernel.  It still compiles.

This set of changes reduces the number of dependencies in LINT/.depend
from about 31000 to about 30000.  This should make LINT kernels
compile a whole 1% faster.  Further reductions to less than 20000
dependencies can easily be made.  E.g., 20 headers of nested spam
from <sys/param.h> for 500 object files gives 10000 dependencies;
less than half of these are real.

65e5a3a9df free_xs must be called at splbio(). This is usually the case since the main
caller is scsi_done which the controller interrupt handlers call.  In the
case of a non-buffer based transaction, the xs structure is freed by the
process that initiated the transfer in scsi_scsi_cmd.  In this case, an
explicit splbio/splx pair around the call to free_xs is required.  Without
the splbio protection, the xs free list could be corrupted, and the type
driver's start routine might run without spl protection.

774fce94c0 Removed volatile' from declaration of time', and removed the resulting

by splclock()/splx().  Accesses outside such a region are invalid, and
splx() must have the side effect of potentially changing all global
variables (since there are hundreds of sort of volatile variables like
`time'), so declaring `time' as volatile didn't have any real benefits.

0b788fa1da Add support to sendmsg()/recvmsg() for passing credentials between
processes using AF_LOCAL sockets. This hack is going to be used with
Secure RPC to duplicate a feature of STREAMS which has no real counterpart
in sockets (with STREAMS/TLI, you can apparently use t_getinfo() to learn
UID of a local process on the other side of a transport endpoint).

What happens is this: the client sets up a sendmsg() call with ancillary
data using the SCM_CREDS socket-level control message type. It does not
need to fill in the structure. When the kernel notices the data,
unp_internalize() fills in the cmesgcred structure with the sending
process' credentials (UID, EUID, GID, and ancillary groups). This data
is later delivered to the receiving process. The receiver can then
perform the follwing tests:

- Did the client send ancillary data?
	o Yes, proceed.
	o No, refuse to authenticate the client.

- The the client send data of type SCM_CREDS?
	o Yes, proceed.
	o No, refuse to authenticate the client.

- Is the cmsgcred structure the right size?
	o Yes, proceed.
	o No, signal a possible error.

The receiver can now inspect the credential information and use it to
authenticate the client.

of setting it (compiled into vfs_conf.c), but we have a dynamic system

flag in the VFS_SET() VFS declaration, perhaps VFCF_LOCAL, and have the
VFS code propagate this down into MNT_LOCAL at mount time.  The other FS's

c5cb388883 Makefile gram.y scan.l sequencer.h symbol.c symbol.h aic7xxx_asm.c:
New sequencer assembler for the aic7xxx adapters.  This assembler
	performs some amount of register type checking, allows bit
	manipulation of symbolic constants, and generates "patch tables"
	for conditionalized downloading of portions of the program.
	This makes it easier to take full advantage of the different
	features of the aic7xxx cards without imposing run time penalies
	or being bound to the small memory footprints of the low end
	cards for features like target mode.

aic7xxx.reg:
	New, assembler parsed, register definitions fo the aic7xxx cards.
	This was done primarily in anticipation of 7810 support which
	will have a different register layout, but should be able to use
	the same assembler.  The kernel aic7xxx driver consumes a generated
	file in the compile directory to get the definitions of the register
	locations.

aic7xxx.seq:
	Convert to the slighly different syntax of the new assembler.

	Conditionalize SCB_PAGING, ultra, and twin features which shaves
	quite a bit of space once the program is downloaded.

	Add code to leave the selection hardware enabled during reconnects
	that win bus arbitration.  This ensures that we will rearbitrate
	as soon as the bus goes free instead of delaying for a bit.

	When we expect the bus to go free, perform all of the cleanup
	associated with that event "up front" and enter a loop awaiting
	bus free.  If we see a REQ first, complain, but attempt to
	continue.  This will hopefully address, or at least help diagnose,
	the "target didn't send identify" messages that have been reported.

Spelling corrections obtained from NetBSD.

6ae8358759 Fix support for != 512 byte sector devices.
Restores the use of SBLOCK instead of the BSOFF/sectorsize calculation.
Using SBLOCK is bogus however in that it uses DEV_BSIZE instead of
the actual sector size, but that is taken care of in other places.
Changing the SBLOCK would be better, but it affects the system
in other places, and doing it this way makes it possible to
use filesystems that was made before the lite2 merge.

d8d6519c63 Fixed the hash formula. Lite2 doesn't have phashinit(), so Lite2's hash
formula uses `& nchash'.  This is very broken when nchash is a prime
number instead of 1 less than a power of 2, but the Lite2 formula was
merged in.

Merged some cosmetic changes from Lite2, rev.1.21 and Lite1.  The merge
was difficult because the Lite2 code is essentially ours (phk's) except
where Lite2 improved or broke it.

Summary of the Lite2 changes:
- in the copyright, phk's rights have been transferred to the Regents.
  This change should be reviewed.
- nchENOENT went away; the "no" vnode is now simply 0.
- comments were improved.
- style was "improved".
- goto instead of Fanatism (sic) was considered bad :-).
- there are some small changes to support whiteouts.
- new cache entries are added in more cases.  More work is required
  near here to change the hash table size if kern.desiredvnodes is
  changed using sysctl.
- rescanning of the hash bucket in cache_purgevfs() was removed.  This
  change should be reviewed.

3a76a5949b Merged Lite2's vfs_sysctl(). It doesn't fit very well into FreeBSD's

the VFS_GENERIC node from the VFS_VFSCONF leaf, so I only converted
the leaves to the FreeBSD framework.  The error handling isn't quite

8a709f7876 When we perform an "automatic request sense", we issue an untagged command.
The sequencer expects untagged transactions to have the SCBID of the
transaction in the "busy target" array.  So, ensure that the busy entry
is up to date for the target in this case.  The new identify code in the
sequencer that performs additional sanity checking got caught up when a
tagged transaction created an untagged request sense.

In ahc_handle_seqint, ensure that the target ID is taken from the right
place.  In the case of a selection, the ID is in SCSIID.  In the case of
a reconnection it is found in SELID.

bccca068ce Functionalize some code that was repeated throughout the driver.
Fix a bug in the initialization of the busreset_args that left the B channel
args unitialized and the A channel ones initialized to B's vales.  Oops.

If we get a NO_IDENT sequencer interrupt (the reconnecting target didn't
issue an identify or botched it), reset the bus instead of panicing.  We
should be able to recover from this error.

In the AWAITING_MSG handler, order messages by severity.  Since the message
we send is based on a flag on the SCB, it is possible, during error recovery,
to get more than one flag set.  This is fine since any time a new flag is
set, it is meant to take us to a more draconian level of recovery.  This
also ensures that we don't lose any "history" of what the command has gone
through.

When we reset the bus, reset the "send ordered tag" bitmask.

Clear some additional interrupt status when we perform a bus reset.
1997-02-28 03:58:21 +00:00
Justin T. Gibbs
9b2a5540ff No longer clear all interrupt status when the sequencer is reset. The only
time that we really want to do this is when a bus reset causes the sequencer
to be reset and the kernel driver now handles this case.

Remove some reordering in the select2 routine that wasn't necessary.
It was an experimental fix for a race condition I fixed elsewhere, and
confused the code flow.

Don't bother looping on a parity error in the mesgout loop since we can't
see parity errors on out phases.

Clean up the mesgin_identify code.  In the old days, we "snooped" for tag
messages and used this as an indicator of whether or not the target was
using tagged transactions.  This forced the sequencer to ack the identify
before determining if a valid SCB matched the target meaning that an abort
message to handle this case might not be seen before the target entered a
data phase.  Since we can determin the "tagged-ness" of a target by looking
it up in the array of busy targets (recently introduced), we can determine
this up front simplifying the search code as well as ensuring we can follow
the SCSI specs method for rejecting a reselection.

When an SCB is placed on the free list, set its SCB_TAG to SCB_LIST_NULL.
This makes it much easier for the kernel driver to find active SCBs on the
card during error recovery.

d314500e7e This now uses queue macros. Include <sys/queue.h> if !KERNEL to preserve
the documented interface.

a8687b6dcd Added some ufs #includes so that this compiles with option LOCKF_DEBUG.
Moving this all from ufs wasn't a good move.  At least the debugging
routines depend on the file system.

Cleaned up the LOCKF_DEBUG #includes.

697030ed3d Removed vestiges of Mach lock types.
vm_map.h:
Removed #include of <sys/proc.h>.  curproc is only used in some macros
and users of the macros already include <sys/proc.h>.

cd9307f60d Changed type of t_line from u_char to int. The Lite2 merge blew away
rev.1.6 which changed it from char to int.

78fd7b3d49 Fixed namei caching for LOOKUPs. It was broken for lstat() and olstat().
Successful lstat()s purged an existing entry as well as not caching the
result.

This bug was introduced in Lite1 by setting the LOCKPARENT flag for
[o]lstat() in order to support the inherit-attributes-from-parent-
directory misfeature for symlinks.  LOCKPARENT was previously only set
for CREATEs and DELETEs.  It is now set for LOOKUPs, but only for
[o]lstat(), so the problem wasn't very noticeable.

25ed2ac223 Changed #ifdef COMPAT_PRELITE2' to #ifndef NO_COMPAT_PRELITE2' so that
the old VFS_VFSCONF sysctl is enabled by default.

Initialize the vfc_vfsops field to non-NULL in sysctl_ovfs_conf()
so that the old VFS_VFSCONF sysctl actually works.  The old (still
current) getvfsent.c uses this "kernel-only" field to decide which
vfs's are configured (the old implementation returned null entries
for unconfigured vfs's).

old nfs mount calls are supported by default.

4e605384b5 Don't rely on AAP(Auto Access Pause) when queueing SCBs to the card. This
will increase the overhead of queueing a command, but some recent bug reports
make me believe that AAP isn't really working and that we are losing some
SCBs from the input queue.  Hopefully this will cure that problem.

Fix some bugs in the error recovery code.  Mainly these could cause us to
inadvertantly forget to untimeout an SCB that was recovered causing later
confusion.

70e534e78f Pass P_SUGID on to the child of a fork(). It was possible to get rlogin
to coredump previously since it (somewhat uniquely) is setuid and forks
without execing, and thus without passing P_SUGID the child could
coredump and possibly divulge sensitive information (such as encrypted
passwords from the passwd database).

of DEFS.h which renamed it.
