e14e57c697 Set RELDATE=300000. With the parallel version development, it has
become impractical to distinguish versions using "real" release dates, so
might as well make it correspond to real version number (-current is
on the 3.0 branch) so at least the feature increments are guaranteed to
be linear.

965388b530 Fix from PR #2757:
execve() clears the P_SUGID process flag in execve() if the binary
executed does not have suid or sgid permission bits set.

This also happens when the effective uid is different from the real
uid or the effective gid is different from the real gid. Under
these circumstances, the process still has set id privileges and
the P_SUGID flag should not be cleared.

87dca7091f Fix some more problems in the recovery code.
Cleanup of the disconnected list was broken in the SCB paging case
    (confusion of NULLand SCB_LIST_NULL)
Implement a clean mechanism for determining that we have exited the timeout
    state and test for this in ahc_done instead of all over the place.
Bring back the use of AAP (Auto Access Pause) I don't think it was the
    true cause of the bus hangs people were reporting.
We want to reset the bus if we've been through an Abort action, not if
    we are a recovery SCB (one implies the other, but not vice-versa).

9c02696981 Convert raw IP from mondo-switch-statement-from-Hell to
pr_usrreqs.  Collapse duplicates with udp_usrreq.c and
tcp_usrreq.c (calling the generic routines in uipc_socket2.c and
in_pcb.c).  Calling sockaddr()_ or peeraddr() on a detached
socket now traps, rather than harmlessly returning an error; this
should never happen.  Allow the raw IP buffer sizes to be
controlled via sysctl.

for pr_usrreqs.

5e400d3141 Enlarge the message out buffer from 6 to 8 bytes. Now that sync and wide
negotiation messages may be tagged, we were overrunning the old buffer.
The variable that was getting squashed is updated before the message goes
out, causing corrupted SDTR or WDTR messages.  Depending on the phases
traversed before message out, this could cause the wrong offset to be
negotiated allowing data overruns to occur.  The problem is easier to
detect with wide targets on the chain since the allowed offset is smaller.

Also removed the unnecessary  clearing of SPIORDY during the message out
phase.  We don't rely on SPIORDY any more.

a962df746e 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.

8f26a5330a 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).

23a89f2e84 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.

2af96e689c 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).

9e8f1bd4ec Select between the generic math functions and the i387-specific ones
at runtime.

etc/make.conf:
Nuked HAVE_FPU option.

lib/msun/Makefile:
Always build the i387 objects.  Copy the i387 source files at build
time so that the i387 objects have different names.  This is simpler
than renaming the files in the cvs repository or repeating half of
bsd.lib.mk to add explicit rules.

lib/msun/src/*.c:
Renamed all functions that have an i387-specific version by adding
`__generic_' to their names.

lib/msun/src/get_hw_float.c:
New file for getting machdep.hw_float from the kernel.

sys/i386/include/asmacros.h:
Abuse the ENTRY() macro to generate jump vectors and associated code.
This works much like PIC PLT dynamic initialization.  The PIC case is
messy.  The old i387 entry points are renamed.  Renaming is easier
here because the names are given by macro expansions.

7319648860 Fix the mechanism for choosing wehether to save the slow-start threshold
in the route.  This allows us to remove the unconditional setting of the
pipesize in the route, which should mean that SO_SNDBUF and SO_RCVBUF
should actually work again.  While we're at it:

- Convert udp_usrreq from `mondo switch statement from Hell' to new-style.
- Delete old TCP mondo switch statement from Hell, which had previously
  been diked out.

8f1bd632d4 Provide PRC_IFDOWN and PRC_IFUP support for IP. Now, when an interface
is administratively downed, all routes to that interface (including the
interface route itself) which are not static will be deleted.  When
it comes back up, and addresses remaining will have their interface routes
re-added.  This solves the problem where, for example, an Ethernet interface
is downed by traffic continues to flow by way of ARP entries.

1f8c9c194a Provide an alternative mbuf cluster allocator which permits use of
clusters greater than one page in length by calling contigmalloc1().
This uses a helper process `mclalloc' to do the allocation if
the system runs out at interrupt time to avoid calling contigmalloc
at high spl.  It is not yet clear to me whether this works.

8a5f6f3073 For large values of sb_max or MCLBYTES, it was possible for the expression
sb_max * MCLBYTES / (MSIZE + MCLBYTES)
used in sbreserve() to overflow, causing all socket creation attempts
to fail.  Force the calculation to use u_quad_t's, which makes overflow
less likely.

c931f90b1f Get defaults for the boot device (and flags) from the file
"boot.config" (relative to the root directory on the 'a' partition
on the first BSD slice) if it exists.  If it doesn't exist, then
the only visible changes should be that the kernel name isn't reset
to "/kernel" after looking it up fails and that the default name
is now "kernel".

The new function readfile() can be used for other things:
- reading help messages.
- reading splash screens.
- reading userconfig info.

9f7ccdfa28 Moved definition of FUNCTION_ALIGNMENT to a machine-dependent place.
Changed it from 4 to 16 for i386's.  It can be anything for i386's,
but compiler options limit it to a power of 2, and assembler and
linker deficiencies limit it to a small power of 2 (<= 16).
We use 16 in the kernel to get smaller tables (see Makefile.i386 and
<machine/asmacros.h>).  We still use the default of 4 in user mode.

Use HISTCOUNTER instead of (*kcount) in the definition of KCOUNT()
for consistency with other macros.
