delta touched the Name Description (Nd). It introduced a grammar
error and did not fix the extraneous punctuation (Nd lines are not
terminated with a period).
Use that to be the final arbiter of whether or not to build the
librsaintl.so plugin for openssl/openssh. Add a magic WANT_RSAINTL flag
to force building even if USA_RESIDENT=YES.

when code tries to examine the returned host name, it dereferences a null

Read permissions are set when the SS_CANTRCVMORE flag is _not_ set and the
receive buffer is empty.
Write permissions are set when SS_CANTSENDMORE is _not_ set.
o Set access mode to -r--r--r-- if SS_CANTRCVMORE is set and the receive
buffer is empty.
o Set access mode to --w--w--w- is SS_CANTSENDMORE is set.

VIS_HTTPSTYLE is a new encoding style for use in vis(), strvis() and
strvisx() that escapes characters according to RFC 1808 (URI encoding).
Since decoding of these require different detection of start-points of
escaped characters, VIS_HTTPSTYLE can be given as flag to unvis().
unvis() will then properly decode URIs.
A new function appeared, strunvisx(): strunvisx() behaves similar as
strunvis(), with one exception: It has an additional flag parameter,
which is passed to unvis() to archive the effect I described above.
- Add 2 explicit (paranoid?) memory barriers in the
interrupt code (After the reading of the `flag' and
prior to looking at the data, of course. :-) ).
- Remove obsolete informations from the README.sym file.

acting as a left control key. Many want a control key in the "real"
place, but still want the keymap to match the printed keys as much
as possible.
Inspired by obrien's us.pc-ctrl.kbd keymap, although I've had these
in my tree for a long time (since the left control key on my laptop
stopped working :)
1) (Biggest) I tried long-and-hard to keep the version number (5.006)
backwards compatible with FreeBSD; I have lost this battle, and
must defer to the Perl convention (5.6.0). Victims include suidperl.
this means that dirs with a name of 5.006 will be replaced with
dirs named 5.6.0 in both /usr/libdata/perl and /usr/local/lib/perl.
2) Errno module is added.
3) Alpha bits extensively tweeked after a Beast-build.

At the time we search the pattern for the "must" string, we now compute
the longest offset from the beginning of the pattern at which the must
string might be found. If that offset is found to be infinite (through
use of "+" or "*"), we set it to -1 to disable the heuristics applied
later.
After we are done with pre-matching, we use that offset and the point in
the text at which the must string was found to compute the earliest
point at which the pattern might be found.
Special care should be taken here. The variable "start" is passed to the
automata-processing functions fast() and slow() to indicate the point in
the text at which they should start working from. The real beginning of
the text is passed in a struct match variable m, which is used to check
for anchors. That variable, though, is initialized with "start", so we
must not adjust "start" before "m" is properly initialized.
Simple tests showed a speed increase from 100% to 400%, but they were
biased in that regexec() was called for the whole file instead of line
by line, and parenthized subexpressions were not searched for.
This change adds a single integer to the size of the "guts" structure,
and does not change the ABI.
Further improvements possible:
Since the speed increase observed here is so huge, one intuitive
optimization would be to introduce a bias in the function that computes
the "must" string so as to prefer a smaller string with a finite offset
over a larger one with an infinite offset. Tests have shown this to be a
bad idea, though, as the cost of false pre-matches far outweights the
benefits of a must offset, even in biased situations.
A number of other improvements suggest themselves, though:
* identify the cases where the pattern is identical to the must
string, and avoid entering fast() and slow() in these cases.
* compute the maximum offset from the must string to the end of
the pattern, and use that to set the point at which fast() and
slow() should give up trying to find a match, and return then
return to pre-matching.
* return all the way to pre-matching if a "match" was found and
later invalidated by back reference processing. Since back
references are evil and should be avoided anyway, this is of
little use.
instead of a struct iovec * array and int len. Get rid of stupidly trying
to allocate all of the memory and copyin()ing the entire iovec[], and
instead just do the proper VOP_WRITE() in ktrwrite() using a copy of
the struct uio that the syscall originally used.
This solves the DoS which could easily be performed; to work around the
DoS, one could also remove "options KTRACE" from the kernel. This is
a very strong MFC candidate for 4.1.
