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...

on the command line. The latter must be requested explicitely.
Intended for "fixes" that are dangerous in some way, because they might
remove files that are still in use, for example.
Make the "sendmail" item disabled by default, it removes sendmail

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.
the history buffer that require knowledge of the readline internals to
make safe (it "knows" that GNU readline mallocs certain returned data,
and thus, with libedit, happily calls free on static variables).
using a #define to turn one into the other, this is pointless and causes
more portability issues than it solves (admittedly, in the year 1702 when
this code was written the opposite may have been the case).
This allows the mouse to be used properly in consoles with different sizes:

be reclaimed from under while we are warming the getattr cache.
Shuffle some code to prevent the effects. Theoretically the race
is still possible, but I don't think it will happen in practice.
In any case, the code could benefit from some more dusting.
getattr are usually still outstanding when we already would like
the result. Instead of issueing another stat which will be serviced
only after all the other entries in the directory, record all the
outgoing readdir getattr buffers and if we encounter an outstanding
request when we need to fetch attrs, do a puffs_framev_framebuf_ccpromote()
wait for it instead of firing off the second query. This shaves
almost 10% off the time for ls -lR.
Also, get rid of the SUPERREADDIR conditional, since it has penetrated
the code quite a bit and the #ifdef SUPERREADDIRs were starting to
look like tagliatelle alla bolognese (n.b. I love how it looks,
but I wouldn't like it either if my tagliatelle alla bolognese
looked like psshfs code). Maybe it should be re-introduced in the
form of a switch?
a bit differently: when reading the directory, store all getattr
caching queries and fire off only when the directory read is
complete. That way the common sequence is not [readdir, lots of
async getattr requests, readdir EOF] but rather [readdir, readdir
EOF, lots of async getattr]. This speeds up ls -lR by about 25%
(on my LAN).
equal, larger, respectively instead of 0/1 for non/equal. This
will allow sorting the buffers for faster matching in libpuffs.
While here, change the name from respcmp to framecmp, as that better
reflects the purpose.
NOTE! there is no obvious way to make compilation fail for file
systems which may already be using this feature (although I don't
think there are any outside our tree, as the feature is two weeks
old). Nevertheless, non-updated file systems will fail very quickly.
