Nikola Forró 85a7acd768 nsswitch.conf.5: Update NSS compatibility mode description 
From the current description of NSS compatibility mode it seems
that /etc/passwd is the only file where special entries are
permitted.  But "compat" service can also be specified for group
and shadow databases, so this needs to be changed.

The list of special entries is for passwd database only, group
and shadow databases are not mentioned.  Because group database
does not support netgroup special entries and it deals with
groups, not users, it is better to make a separate list
of entries for it.

It is true that the default source for the compat pseudo-databases
is "nis", but it can be overridden by any NSS service, not just
"nisplus". Even "compat" itself can be specified as the source for
the pseudo-databases, but doing that of course leads to infinite
recursion, so it makes sense to disallow that.

The information was obtained from glibc source code, namely from
the following files:
nis/nss_compat/compat-pwd.c
nis/nss_compat/compat-grp.c
nis/nss_compat/compat-spwd.c

Ross Zwisler db02982a48 core.5: Add info about DAX coredump filtering flags 
Kernel 4.4 added two new core dump filtering flags,
MMF_DUMP_DAX_PRIVATE and MMF_DUMP_DAX_SHARED.

These flags allow us to explicitly filter DAX mappings.
This is desirable because DAX mappings, like hugetlb
mappings, have the potential to be very large.

Carlos O'Donell 427cee53f0 hosts.equiv.5: Fix format, clarify IdM needs, and provide examples. 
In some recent work with a Red Hat customer I had the opportunity
to discuss the fine nuances of the ruserok() function and related
API which are used to implement rlogin and rsh.

It came to my attention after working with QE on some automated
internal testing that there were no good examples in the hosts.equiv
manual page showing how the format was supposed to work for this
file and for ~/.rhosts, worse the "format" line showed that there
should be spaces between arguments when that would clearly lead
to incorrect behaviour. In addition some things that the format
allows you to write are just wrong like "-host -user" which makes
no sense since the host is already rejected, and should be written
as "host -user" instead. I added notes in the example to make it
clear that "-host -user" is invalid.

I fixed three things:

(a) The format line.
- Either +, or [-]hostname, or +@netgrp or -@netgrp.
- Either +, or [-]username, or +@netgrp or -@netgrp.
- You must specify something in the hostname portion so remove
  optional brackets.

(b) Clarify language around credentials
- If the host is not trusted you must provide credentials to
  the login system and that could be anything really and it
  depends on your configuration e.g. PAM or whatever IdM you have.

(c) Provide real-world examples
- Provide several real world examples and some corner case
  examples for how you would write something. Hopefully others
  can add examples as they see fit.

The timezone of LC_TIME is not in POSIX, only 6 (out of ~300)
glibc locales define it, the glibc code comment below from
glibc.git/programs/ld-time.c seems to suggest it's not a good
idea, and there's been a proposal in upstream [1] to remove the
existing timezone definitions from glibc locales so I think
it's actually better to leave this one undocumented:

/* XXX We don't perform any tests on the timezone value since this is
   simply useless, stupid $&$!@...  */

Marko Myllynen d850c7e08f repertoiremap.5: Symbolic names AKA mnemonics 
A long time ago in glibc, repertoire maps were used (but they
were removed already in 2000), those mapping files were named
as mnemonics, so "mnemonic" is a term that would almost
certainly come up if somebody studies glibc side (perhaps even
the related standards like ISO 9945 [which I don't have access
to]) so I thought it's worth to mention to term in the man page
to make sure we're talking about the same thing, otherwise
someone might wonder is that something different or not.

IOW, symbolic names and mnemonics are often used interchangeably,
let's mention the other often used term in the page, too.

Elie De Brauwer 4f747ba0b2 proc.5: Document /proc/sys/vm/compact_memory 
Since 2.6.36 [1] CONFIG_COMPACTION is supported in Linux (for a
detailed explanation see [2]). But in essence the contents of
/proc/buddyinfo shows how much contiguous areas of a certain
size are available. These numbers are not actually up to date
as the Linux kernel will implicitly trigger compaction
(+- defragmentation) when an allocation is done.  This makes it
difficult since you can't predict upfront whether or not a large
allocation will succeed or not.  By using
/proc/sys/vm/compact_memory you can explicitly trigger compaction
to occur and /proc/buddyinfo will give a more realistic view on
the available memory in contiguous areas.

This patch updates proc.5 to explain the usage of this file and is
inspired by Documentation/systcl/vm.txt [3]

Based on commit [1], ithe no-tld-query option exists for
resolv.conf configuration file.  Description of this option
is provided in [2]. This patch just copies this option
into resolv.conf.5 man page. Plus changes 'a' member
into 'an' before 'unqualified name as if it ...'
on the third line of [2]. Based on [3], this option
was added in glibc 2.14 as solving [4] bug.
