50d503b781 Workaround for nscd(8) failure with large entries.
It fixes a case where eg a 2KB group entry would take several seconds
to complete with cache enabled in nsswitch.conf.

8af0c00bd6 Fix non-recoverable name resolution failures due to negative cache
entries never expiring. This patch honours the negative cache timeout.

To test/experience the failure do the following:

1. Edit /etc/ncd.conf to adjust the cache timeouts as follows:

	positive-time-to-live hosts 30
	negative-time-to-live hosts 1

2. Ensure that nsswitch.conf hosts line contains something like:

	hosts: files cache dns

	Note that cache must be specified before dns.

3. Start nscd.

4. Run the following command:

	while true; do nc -z -w 3 www.google.com 80; sleep 5; done

5. While running the command, remove or comment out all nameserver
   statements in /etc/resolv.conf. After a short while you will notice
   non-recoverable name rsolution failures.

6. Uncomment or replace all nameserver statements back into
   /etc/resolv.conf. Take note that name resolution never recovers.
   To recover nscd must be restarted. This patch fixes this.

ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

configuration value is an integer count of seconds, it is not a timeval.
Using memcpy() to copy a timeval from it put garbage into the tv_usec

a397989d4e Add the possibility to specify a threshold for the number of negative cache
results required to have the cache return lookup failure.

A new configuration parameter is introduced, which must be set to a value
greater than 1 to activate this feature. The default behavior is unchanged.

The purpose of this change is to allow probes for the existence of an entry
(which are expected to fail), before that entry is added to one of the
queried databases, without the cache returning the stale information from
the probe query until that cache entry expires. If, for example, a new user
account is created after checking that the new account name is available,
the negative cache entry would prevent immediate access to the account.

For that example, the new configuration option

negative-confidence-threshold passwd 2

will require a second negative query result to consider the negative cache
entry for a passwd entry valid, but if the user account has been created
between the queries, then the positive query result from the second query
will be cached and returned.
