Michael Kerrisk 2927055043 proc.5: Rework the description of /proc/PID/mountinfo parent-ID field 
After comments from Miklos, and further digging in the kernel
source that showed that chroot() can also result in "hidden"
parent-IDs in mountinfo, I've revised the description of
mountinfo.

In fs/proc_namespace.cs::how_mountinfo() there is:

        /* mountpoints outside of chroot jail will give SEQ_SKIP on this */
        err = seq_path_root(m, &mnt_path, &p->root, " \t\n\\");
        if (err)
                goto out;

I instrumented the 'if (err)' code path with printk()
to show that there is indeed a record corresponding to the
parent-ID for the process root that is being skipped.

Michael Kerrisk 35cf1b9397 proc.5: Correct the description of the parent mount ID for /proc/PID/mountinfo 
I do not have an exact handle on the details, but I can see
roughly what is going on.  Internally, there seems to be one
("hidden") mount ID reserved to each mount namespace, and that ID
is the parent of the root mount point.

Looking through the (4.14) kernel source, mount IDs are allocated
by a kernel function called mnt_alloc_id() (in fs/namespace.c),
which is in turn called by alloc_vfsmnt() which is in turn called
by clone_mnt().

A new mount namespace is created by the kernel function
copy_mnt_ns() (in fs/namespace.c, called by
create_new_namespaces() in kernel/nsproxy.c). The copy_mnt_ns()
function calls copy_tree() (in fs/namespace.c), and copy_tree()
calls clone_mnt() in *two* places.  The first of these is the call
that creates the "hidden" mount ID that becomes the parent of the
root mount point. (I verified this by instrumenting the kernel
with a few printk() calls to display the IDs.)  The second place
where copy_tree() calls clone_mnt() is in a loop that replicates
each of the mount points (including the root mount point) in the
source mount namespace.

Since the symbolic links for pipes and sockets do not refer to real

still have mode and ownership information (revealed e.g. by `stat -L`),
so let's point this out in the manpage.

Paul Eggert 72942d65ad tzfile.5: Sync from tzdb upstream 
This makes tzfile.5 a copy of the tzdb version, except that the
tzdb version's first line is replaced by man-pages boilerplate.
The new version documents version 3 format, among other things.
Also, it removes the "Summary of the timezone information file
format" section, which should no longer be needed due to
improvements in the the part of the man page.

Marko Myllynen a581f7593b locale.5: Refer to existing locales for encoding details 
Mike Fabian and Rafał Luzynski were recently named as glibc
localedata maintainers [1] and after that there's been active
development on this front, including discussion whether it would
be ok to use ASCII or some other encoding as values for actual
locate data.

Since I don't think it would make sense to try to have different
explanation for each glibc version on the locale(5) man page, I'm
proposing that we apply the below patch so that we refer to
existing locale definition files in general and not spell out the
exact format or any certain locale as a definitive guideline.

If the situation changes in the future or new a new convention
meant to last forever is created then perhaps Mike and Rafał can
provide an update then as needed.

Carlos O'Donell dd9454a654 resolv.conf.5: Timeout does not map to resolver API calls 
I'm posting this patch to clarify the timeout behaviour because
there have been developers who expect this timeout to mean
something it is not.

The timeout (and by proxy attempts) does not map to resolver API
calls.  For example a single call to getent might involve multiple
resolution requests to the resolvers listed in resolv.conf and
each request will use TIMEOUT and be attempted at least ATTEMPT
times. A developer using the resolver API cannot easily compute
any given timeout because the implementation may change e.g. A and
AAAA queries made in parallel.  A system administrator uses this
setting to ensure there is a desirable timeout on any request to
any of the nameservers listed in resolv.conf, but no guarantees
exist beyond that.

included the GNU extensions here, especially as others are not
defined in the elf.h header file as shipped by glibc.

I've mostly used binutils, glibc, breakpad, and the GABI ELF spec
as sources of data for these fields.

Mike Frysinger 2b3122418d proc(5): Clarify the root symlink and mount namespaces 
If the target process is in a different mount namespace, the root
symlink actually shows that view of the filesystem.  As an example:

    /* Terminal 1 */
    $ unshare -Urnm
    # mount -t tmpfs tmpfs /etc
    # mount --bind /bin /dev
    # echo $$
    17168

    /* Terminal 2 */
    # ls /etc                       # Normal view of /etc files.
    # ls /proc/17168/root/etc       # Empty view of the tmpfs.
    # ls /dev                       # Normal view of /dev files.
    # ls /proc/17168/root/dev       # Contents of /bin files.
