Since then we have living with a GPL'ed find(1) due to grabbing getdate.y
from src/contrib/cvs and its user of the GPL'ed xtime.h. I don't even want
to think about how this could have affected people using our source base.
Would it have been too much trouble to do then what I did now?
Copied getdate.y (public domain) to usr.bin/find and change to use
standard system headers. find(1) now compiles simply with out having
to go to extra effort to do so.

Build fixed on: gcc 3.1 using platforms
we can use td_ucred.
- In killpg1(), the proc lock is sufficient to check if p_stat is SZOMB
or not. We don't need sched_lock.
- Close some races in psignal(). In psignal() there is a big switch
statement based on p_stat. All the different cases are assuming that
the process (or thread) isn't going to change state out from under it.
To ensure this is true, just lock sched_lock for the entire switch. We
practically held it the entire time already anyways. This also
simplifies the locking somewhat and actually results in fewer lock
operations.
- Allow signotify() to be called with the sched_lock held since psignal()
now does that.
- Use td_ucred in a couple of places.
process so it can use td_ucred.
- Require the target process of donice() to be locked when donice() is
called.
- Use td_ucred.
- Lock the target process of p_cansee() and while reading the credentials
of a process.
- Change the logic of rtprio() slightly so it does it's copyin() if needed
prior to locking the target process.
- rtprio() no longer needs Giant. In theory with full KSE it would still
need Giant to protect p_ucred of curproc for the p_canfoo() functions
but p_canfoo() will be changing to using td_ucred of curthread before
full KSE hits the tree.
of a process pointer.
- Move the p_candebug() at the start of procfs_control() a bit to make
locking feasible. We still perform the access check before doing
anything, we just now perform it after acquiring locks.
- Don't lock the sched_lock for TRACE_WAIT_P() and when checking to see if
p_stat is SSTOP. We lock the process while setting p_stat to SSTOP
so locking the process is sufficient to do a read to see if p_stat is
SSTOP or not.
allocate a blank cred first, lock the process, perform checks on the
old process credential, copy the old process credential into the new
blank credential, modify the new credential, update the process
credential pointer, unlock the process, and cleanup rather than trying
to allocate a new credential after performing the checks on the old
credential.
- Cleanup _setugid() a little bit.
- setlogin() doesn't need Giant thanks to pgrp/session locking and
td_ucred.
FIFO or the in-RAM descriptors it will switch to RX_IDLE from where it
is not restarted.
We used to deal with RX_IDLE by doing a total reinit but this lost
our link and caused a potential 30sec autonegotiation against
switches. This was changed to a less heavyhanded approach, but this
failed to restart the receiver it it were in the RX_IDLE state.
This change adds the RX_IDLE and the RX_FIFO_OFLOW conditions as
triggers for interrupts and receive side processing, and restarts
the receiver when it is RX_IDLE.
Remove the #ifdef notyet'ed nge_rxeoc() function.

1) Add missing initialisers.
2) Avoid shadowing rcswhich.
3) Use intmax_t and %j for printing rather than quad_t and %q.
4) Don't modify a variable twice between sequence points.

The problem seems to be that in str_concat(), the string is not
terminated when the length of the second string is 0.
This apparently can happen during null suffix rule processing.

present, this field specifies the media volume that the disc is
contained on. If the volume of a given packages is different than the
current volume of mediaDevice, then the user is prompted --
"This is disc #%d. Package %s is on disc #%d\n"
"Would you like to switch discs now?\n"
If the user selects yes, then DEVICE_SHUTDOWN is called and the user
is then prompted --
"Please remove disc #%d from you drive, and add disc #%d"
This works well for a carefully crafted INDEX file, but more work
needs to be done to sort dependencies on a given package based on the
volume that they reside on, to minimize the amount of disc flipping
required of the user.
This commit is a no-op for normal INDEX files and FreeBSD CDs. These
additional features are only used if the INDEX and cdrom.inf file have
multi-volume support.

Don't be too overzealous with the printing of ks_calls in the total
statistics, cut back from 20 to 13 positions to print (which should last
a couple of years easily (20 digits is enough for 3168 years of calls at a
measly billion (10^9) calls per second.)).

o Implement -c (clear) to clear previously kept headers (note that
dumps not cleared will remain until -c is used),
o Implement -f (force) to allow re-saving a previously saved dump,
o Implement -k (keep) and make clearing the dump header the default,
o Implement -v (verbose) and make most output conditional upon it,
o Emit minimal output for the non-verbose case with the assumption
that savecore is run mostly from within /etc/rc,
o Update usage message to reflect what is and what's not,
o mark -d as obsolete.
Low-level changes:
o Rename devname to device, for devname mirrors a global declaration
and GCC 3.x warns about it,
o Open the dump device R/W for clear and !keep to work,
o Reorder the locals of DoFile according to style(9),
o Remove newlines from strings passed to warn* and err*,
o Use stat(2) to check if a dump has been saved before,
o Truncate existing core and info files to support force,
o First check for the magic and the version before we complain about
parity errors. This prevents emitting parity error messages when
there's no dump,
o Keep track of the number of headers found and the number of headers
saved to support the minimal output,
o Close files we opened in DoFile. Not critical, but cleaner.
