by providing the opportunity to edit inetd.conf during the system
installation process. The following modifications were made:
(1) Expand the Anonymous FTP description dialog to indicate that inetd
and ftpd must be enabled before it can be used.
(2) Introduce a new configInetd() pair of dialogs, the first describing
inetd, giving a couple of examples of services that require it, and
hinting at potential risk, then asking the user if they wish to
enable it. The second indicates that inetd.conf must be configured
to enabled specific services, and asks if the user would like to
load inetd.conf into the editor to modify it. Add this
configuration action to the index.
There are some further improvements that might be considered:
(1) Provide a more inetd.conf-specific configuration tool that speaks
inetd.conf(5). However, this is made difficult by the "yet another
configuration format" nature of inetd.conf, as well as its use of
commenting to disable services, rather than an in-syntax way to
disable a service without commenting it out. Submissions here
would probably be welcome.
(2) There's some overlap between settings in the somewhat obtuse
Security Profile mechanism and other settings, including the inetd
setting, and NFS server configuration. As features become
individually tunable, they should probably be removed from the
security profile mechanism. Otherwise, somewhat counter-intuitively,
sysinstall (in practice) queries multiple times whether inetd, nfsd,
etc, should be enabled/disabled. A possible future direction might
be to drive profiles not by degree of paranoia, rather, the set
of services desired. Or simply to remove the Security Profile
mechanism and resort to feature-driven configuration.

When reading the code I had to stop, say "ok, what does *these*
modifications of strl*() do? Pull out grep. Oh, not in add/, maybe above
in ../lib/? Yep. So what do they do? Comments above them are misleading,
guess I'll have to read the code. Oh, they just test strl* against the
size and return the result of the test. Now I can continue to read the
code I was.
The uses of s_strl*() then test that result and errx()'s.
Lets think about the "optimized" code I am removing:
In general the compiler pushes the three args to strl* onto the stack and calls
s_strl*. s_strl* has to indirectly access 3 args from the stack. Then push
them on the stack a 2nd time for the real strl* call. s_strl* then pops the
return from strl* off the stack; or moves it from the register it was returned
in, to the register where tests can happen. s_strl* then pops the three
arguments to strl*. Perform the test, push the result of the test, or move it
from the result register to the return value register. The caller to s_strl*
now has to either pop the return value of s_strl* or move it from the return
value register to the test register. The caller then pops the three args to
s_strl* off the stack (the same args that s_strl* itself had to pop off after
the real call to strl*). The s_strl* caller then performs a simular test to
what has already been done, and conditionally jumps. By doing things this way, we've given the compiler optimizer less to work with.
Also, please don't forget the that call to s_strl* has possibly jumped to code
not in the cache due to being far away from the calling code, thus causing a
pipeline stall.
So where is the "optimization" from s_strl*?
It isn't code clarity.
It isn't code execution speed. It isn't code size either.

Problem 1 is that the config entry hangup flag is zeroed only at
CONNECT_ACTIVE_IND in msghdl.c. If any (other) call is disconnected
after EV_MDO and before CONNECT_ACTIVE_IND, the cleanup routine will
disconnect the in-progress dialout as well, if its hangup flag is
nonzero (which it is likely to be) after the previous incarnation of the
cfg entry. Patch-1 fixes this by clearing the hangup flag as soon as a
cfg entry is reserved for the call.
Submitted by: Juha-Matti Liukkonen <jml@cubical.fi>
Problem 2 is that doing a local hangup (eg. by writing "H" to the
dialout device) to a call which is already disconnected results in isdnd
moving the cfg entry to an illegal state, from which there is no
recovery. This is tricky because there is no way to synchronize local
hangup with the remote end (ie. the callee can always hang up at an
inconvenient time)! Hence, patch-2 alters fsm.c's EV_DRQ state table
such that the local hangup request is processed or ignored in most
states, even for disconnected calls.

The 5% ttl reduction can cause the glue IN A to timeout before the NS
record in certain situations, such as when the domain owner does not match
up NS records with the NIC. This behavior by domain owners is becoming
more common as primary zone serving iterates through another glue level
(i.e. exodus hosts the master NS's but the customer then redirects the
NS's to the real DNS servers). The result is that named would appear to
work properly for about 40 minutes, and then unexpectedly fail for that
zone. This causes named to behave very inconsistently and a google search
shows that it has obviously frustrated many, many people. So until the bind
guys make named behave consistently (either fail instantly or accomodate the
case), we need to set this option to accomodate the case. The result
will be much more consistent behavior and fewer head-scratching failures.
