is swapped in. Also, remove unnecessary map locking/unlocking during
selection of processes to be swapped out.
This code might afford proper panics as opposed to spontaneous reboots
on certain systems. This should allow us to debug these problems better.
David Greenman, it has been determined that the more sophisticated code
only made a very minor difference in fault performance. Therefore, this
code eliminates some of the complication of the fault code, decreasing
the amount of CPU used to scan shadow chains.
#ifdef out a number of calls to free() left over from the original
GNU ypserv implementation. As near as I can tell, the Berkeley DB
package does its own garbage collection, hence the caller doesn't
have to worry about free()ing the memory returned in the DBT
structures during lookups (I'm still not 1005 sure about this:
the DB code is very hard to follow. I must use dynamically
allocated memory since you can retreive arbitrarily large records
from a database, but I'm not sure where it ends up letting go
of it). This was not true with GDBM; you had
to do your own garbage collection.
The general rule is that if you allocate memory inside an RPC
service routine, you have to free() it the next time the routine is
called since the underlying XDR routines won't do it for you.
But if the DB package does this itself, then we don't need to do
it in the main program.
Note that with the original malloc(), there were never any errors
flagged. phkmalloc complained quite loudly.
support for EXT2FS. Note that the Sig-11 problems appear to be caused by
this, but there is still probably an underlying VM problem that let this
clustering bug cause vnode objects to appear to be corrupted.
The direct manifestation of this bug would have been severely mis-read
files. It is possible that processes would Sig-11 on very damaged
input files and might explain the mysterious differences in system
behaviour when phk's malloc is being used.
the way it stores and handles "interface". The previous behavior resulted
in strange output from 'w' and 'ps' when an interface specification was
given to netstat.
with the driver's stability now. I've not had a single problem with it for
weeks.. All that remains is a bit of performance tuning, and finishing
the manpages.
Fix loopback and discard interfaces to understand BPF writes.
(These two from Bill Fenner to fix PR 512.)
Move ifpromisc() from bpf.c to if.c as suggested by comment in BPF.
Send a notice to the log when promiscuous mode is enabled.

wouldn't fly if the kernel didn't have COMPAT_43.

time ago. I left in Garrett's one, because his was in the 4.4-Lite-2
location, making any diffs just that little bit smaller.
I presume this choice means that netstat needs to be recompiled before
"netstat -s" will give a meaningful answer on tcp stats.
