some symbols in X_db_search_symbol(). Reject the same symbols that
rev.1.13 did (all except STT_OBJECT and STT_FUNC), except don't reject
typeless symbols. This keeps the typeless symbols in non-verbosely
written assembler code visible, but makes file symbols invisible. ELF
file symbols have type STT_FILE and value 0, so this stops small values
and offsets sometimes being displayed in terms of the first file symbol
in the kernel (usually device_if.c). I think it rejects some other
unwanted symbols (small absolute symbols for things like struct offsets).
It may reject some wanted symbols (large absolute symbols for addresses
like PTmap).
about because we're still tier 2 and our current compiler, as well
as future compilers will not support varargs. This is mostly a
no-op in practice, because <sys/varargs.h> should already cause
compile failures.
(1) Don't modify the configuration of the NFS server as a result of
selecting a profile. We already explicitly prompt for the NFS
server configuration during install, and the user may not get
much advance notice that we're turning it off again. Instead,
use profiles (for better or for worse) only for security tuning.
(2) Don't modify the sendmail setting as part of the security profile:
use the default from /etc/defaults/rc.conf rather than explicitly
specifying. Note that the default in /etc/defaults/rc.conf is
more conservative than the explicit rc.conf entry added by
sysinstall during install, as it does not permit SMTP delivery.
(3) Update "congratulations on your profile" text to reflect these
changes.
Note that security profiles now affect only the securelevel and sshd
settings. My leaning would be to make sshd an explicit configuration
option, move securelevels to the security menu, and drop security
profiles entirely. However, that requires more plumbing of sendmail
than I'm currently willing to invest.
We may want to add a "permit SMTP delivery" question to the install
process.
On ia64, where there's no libc_r at all, libkse is now the default
thread library by virtue of these links.
The reasons for this change are:
1. libkse is slated to become the default thread library anyway,
2. active development and maintenance is only present for libkse,
3. GNOME and KDE, both in the process of being supported on ia64,
work better with KSE; even on ia64.
use the ability on ia64 to map the register stack. The orientation of
the stack (i.e. its grow direction) is passed to vm_map_stack() in the
overloaded cow argument. Since the grow direction is represented by
bits, it is possible and allowed to create bi-directional stacks.
This is not an advertised feature, more of a side-effect.
Fix a bug in vm_map_growstack() that's specific to rstacks and which
we could only find by having the ability to create rstacks: when
the mapped stack ends at the faulting address, we have not actually
mapped the faulting address. we need to include or cover the faulting
address.
Note that at this time mmap(2) has not been extended to allow the
creation of rstacks by processes. If such a need arises, this can
be done.
Tested on: alpha, i386, ia64, sparc64
o It is the /usr/include files, not the /usr include files.
o Document the practice of converting to the c99 standard uintXX_t
form from the older, but non-standard, BSD-style u_intXX_t. This
has been going on in the tree for a while now, and I've heard other
developers also state that this conversion is happening. Note also
that this is a slow process and should be treated like whitespace
changes.

- Make the device list compact, since it is getting rather large.

MFC after: 2 weeks
there to support sysinstall, and enabling DEBUG creates spurious
console output that can't be read anyway... This slightly cleans up
the visual impression of the system install by not spamming the console
during the labeling of the disks.
- Use a more robust check to determine if we need to load ipl.ko.
- Don't try to run ipf -E if ipfilter is already enabled. Look at
the net.inet.ipf.fr_running sysctl to figure this out. This fixes
a warning message about ipfilter being already initialized.
- Only one ipf -E command is needed. We don't need an extra one for
the -6 case which would only print a warning message about ipfilter
being already initialized.
- Fix one occurence where we were running /sbin/ipf directly without
using the ${ipfilter_program} variable if set.
- In ipfilter_stop(), don't try to save the firewall state tables if
ipfilter is disabled. Similarly, don't try to disable it if it's
already disabled. This fixes some more error messages.
do exactly the same as vop_nopoll() for consistency and put a
comment in the two pointing at each other.
Retire seltrue() in favour of no_poll().
Create private default functions in kern_conf.c instead of public
ones.
Change default strategy to return the bio with ENODEV instead of
doing nothing which would lead the bio stranded.
Retire public nullopen() and nullclose() as well as the entire band
of public no{read,write,ioctl,mmap,kqfilter,strategy,poll,dump}
funtions, they are the default actions now.
Move the final two trivial functions from subr_xxx.c to kern_conf.c
and retire the now empty subr_xxx.c
This is just a cleanup here (modulo rev.1.108 of kern/tty.c), since the
input speed can be different from to output speed and extra code to
handle both speeds naturally handled all cases.
provide no methods does not make any sense, and is not used by any
driver.
It is a pretty hard to come up with even a theoretical concept of
a device driver which would always fail open and close with ENODEV.
Change the defaults to be nullopen() and nullclose() which simply
does nothing.
Remove explicit initializations to these from the drivers which
already used them.
- Removed conversion of a zero input speed to the output speed. This
has been done better in ttioctl() since rev.1.108 of kern/tty.c
almost 5 years ago. comparam() did the conversion incompletely for
the case where the output speed is also zero. It had complications
to avoid using zero speeds, but would still have used a zero input
speed for setting watermarks if kern/tty.c had passed one.
- Never permit the input speed to be different from the output speed.
There was no validity check on the input speed for the case of a zero
output speed. Then we didn't change the physical speeds, but we used
the unvalidated input speed for setting watermarks and didn't return
an error, so ttioctl() stored the unvalidated input speed in the tty
struct where it could cause problems later.
- Removed complications that were to avoid using a divisor of 0. The
divisor is now always valid if the speed is accepted.
cd_setreg() were still using !(read_eflags() & PSL_I) as the condition
for the lock hidden by COM_LOCK() (if any) being held. This worked
when spin mutexes and/or critical_enter() used hard interrupt disablement,
but it has caused recursion on the non-recursive mutex com_mtx since
all relevant interrupt disablement became soft. The recursion is
harmless unless there are other bugs, but it breaks an invariant so
it is fatal if spinlocks are witnessed.
struct msdosfsmount so that this file has the same prerequisites as
it used to. The new prerequistite was a meta-style bug. It required
many style bugs (unsorted includes ...) elsewhere.
Formatted prototypes in KNF. Resisted urge to sort all the prototypes,
to minimise differences with NetBSD. (NetBSD has reformatted the
prototypes but has not sorted them and still uses __P(()).)
instances: the memory holding a struct disk should be pre-zeroed so
as to initialize any storage framework private data in the structures
properly. In addition, the memory must be writable so that the
private data may be updated.

APIs permit disk device drivers to register and deregister storage devices
for use by storage device consumers. No doubt this API will change
more as time flies by, but this should be helpful to the creators of
new storage device drivers.
