both the "data" and "prefix" elements are identical. For example, the
two lines
amiga/boot (8) - system bootstrapping procedures
amd64/boot (8) - system bootstrapping procedures
both appear with data = "boot (8) - system bootstrapping procedures" but
with different values for prefix, and we do not want to reject one of
them as a duplicate.
1) Fix an issue where because of the reordering of transform_request
and process_cgi, the cgi-script name was being cut off
by one character (transform_request for some reason
cuts off the leading '/' for the file name as part of its
processing). As an 'easy' fix, simply re-add the '/' to the
front of the filename, which means that we don't have to
mess with the logic that sometimes adds +1 and sometimes doesn't.
2) Work around ridiculous bug in PHP reported by lukem in 2004,
but stubbornly never fixed by the PHP maintainers:
Change the SCRIPT_NAME and SCRIPT_FILENAME variables
to contain the file name only, not the query if one exists.
Having the query in SCRIPT_FILENAME causes php-cgi to not
work, as per the bug information here:
http://bugs.php.net/bug.php?id=28227
3) Fix a memory leak because URL wasn't being freed.
CGI handling, including bin/40355 . There are two main changes here:
1) call process_cgi() after transform_request(), not before. Now it is
possible to have a default cgi handler catch a request for a path that
was produced by transformation, e.g. by index generation -- so now the
index can be "generated" by a CGI if that is what the user desires.
2) More clearly distinguish "file" from "query" portions of the request
URL, so we do not feed ?-suffixed "arguments" to plain files, fail to
match filename extensions due to ?-suffixes, etc.
After this change, there are only two cases which use the "query"
portion of the request (the portion after the ?):
a) A redirect issued by HTTPD will redirect to the new file, but
with the same query string.
b) process_cgi() will, of course continue to use the query string.

when to free them. Now they're owned by utmpentry.c, only. Abolish the
freeutentries() function, which was the wrong abstraction; add instead
endutentries(), which flushes out the internally managed memory.
Update callers as necessary. Some (e.g. talkd) had been leaking memory;
others (e.g. syslogd) had been accidentally freeing and reloading utmp

performed by the pam_conv (PAM conversation) callback, which then
getline()s the PASS reply internally. This involves calling
auth_pam() from user() and caching the result to use later in pass().
This allows the PAM modules to present a different password prompt
dialog if necesary. For example:
Name (localhost:lukem):
331 User lukem accepted, provide password [ otp-md4 89 xxxx12345 ].
versus
Name (localhost:lukem): root
331 User root accepted, provide password.
This is independent of (and effectively exclusive to) USE_SKEY support.
Previously ftpd with USE_SKEY=yes would provide the skey prompt
if the user had an skey configured, even if /etc/pam.d/ftpd didn't
have pam_skey in use.
I.e., ftpd shouldn't need special support for custom password prompts
(such as skey) if PAM is in use.

avoid wasting OS flag bits. In the future we'll probably use fileassoc to
achieve this (once there is a way to make fileassoc persistent) or in the
shorter term libelf, so that we can add and remove the note on demand instead
of burning bits on each binary. Of course since this is a tool, this means
that we'll need to think about how to handle libelf...
FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to
various string and memory copy and set functions (as well as a few system
calls and other miscellany) where known at function entry. RedHat has
evidently built all "core system packages" with this option for some time.
This option should be used at the top of Makefiles (or Makefile.inc where
this is used for subdirectories) but after any setting of LIB.
This is only useful for userland code, and cannot be used in libc or in
any code which includes the libc internals, because it overrides certain
libc functions with macros. Some effort has been made to make USE_FORT=yes
work correctly for a full-system build by having the bsd.sys.mk logic
disable the feature where it should not be used (libc, libssp iteself,
the kernel) but no attempt has been made to build the entire system with
USE_FORT and doing so will doubtless expose numerous bugs and misfeatures.
Adjust the system build so that all programs and libraries that are setuid,
directly handle network data (including serial comm data), perform
authentication, or appear likely to have (or have a history of having)
data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default,
with the exception of libc, which cannot use USE_FORT and thus uses
only USE_SSP by default. Tested on i386 with no ill results; USE_FORT=no
per-directory or in a system build will disable if desired.

In determining when to stop reading segments when counting bytes (-b flag),

they are all full blocks: many could be fragments or inode blocks. This
increases the number of segments per Ifile write, markedly improving the

- avoid double slashes when displaying man pages (got tired
of '/usr/share/man//cat1/man.0').
- got rid of __P() while working on it.
- incorporate some of my old notes explaining how manpath works into the
comments of the code itself.
- renamed some of the vars so that the code is consistent throughout
(and hopefully clearer and easier to understand)
- fixed relative man paths for multiple man pages (man did a chdir()
on the first man page it had to format --- this broke any remaining
relative path man pages left to process). save old directory and
fchdir() back to it after formatting.
- improved doc on "man -h" which does more than just whatis(1) [e.g.
"man -h fopen" prints the required include files and the prototypes
rather than just the one-liner you get with whatis(1)]
- manconf.c now fills in the "len" length field in the TAG/ENTRY
structures (man now uses len).
revise man.conf file reading stuff to return error on failure in
addentry/gettag (fka getlist) rather than just err()ing out. this

(makewhatis, apropos, catman, whatis) to expect this. also remove
__P on updated files.

tested at this point.
free() call, change the allocation policy to leave the responsibility for
