Remove all use of the nfsctl system call.

2016-12-06T16:15:37+00:00

This systemcall was deprecated early in the 2.6 series
as it was replaced by an in-kernel cache which was refilled
using an upcall.  All communication to kernel is now through
the nfsd filesystem.

The nfsctl systemcall itself was removed in 3.1.

It is unlikely to have been used for over a decade.

To remove all uses for the nfsctl systemcall, and call code that only
runs when "new_cache" is false.  We now assume "new_cache" is always
true.

This allows the removal of several files as well as assorted functions.

Remove all use of /var/lib/nfs/xtab

2016-11-15T21:47:03+00:00

/var/lib/nfs/xtab is only used to find out what has been exported to
the kernel.  This is more reliably done by reading
/proc/fs/nfs{,d}/export and nfs-utils uses that file if is available.
So xtab is only need if you have an incredibly ancient kernel which
doesn't have /proc/fs/nfs/export (and so which only supports NFSv2) or
if /proc is not mounted.

Neither of these are credible contexts to run a modern nfs-utils,
so stop creating or reading the xtab file.

nfs-server-generator: avoid using external services.

2016-11-07T19:13:49+00:00

nfs-server-generator is run very early when a lot of services are not
yet started, so it mustn't depend on them.  Currently it can try to
use hostname lookup and syslog.  Using hostname lookup can cause
errors and when these are logged via syslog, it can cause the
generator to block indefinitely

Hostname-lookup is not needed, as we don't use the host issue,
and sending message to stderr is sufficient for the generator.

Disabling syslog is easy - call a function that sets a static variable.

Disabling hostname lookup requires adding an "ignore_hosts" flags to
export_read and export_d_read().

Move export_d_read() to support/export/export.c

2016-08-20T14:59:14+00:00

This places it in the same place as the similar export_read(),
and allows it to be called from other programs.

exportfs: replace one xlog(D_GENERAL) in host_canonname()

2016-05-02T15:57:31+00:00

If we fall back to using the numeric host then we shouldn't call
xlog with D_GENERAL.  That can cause 'exportfs -u' to exit with a 1
if, for example, you have exports using ip addresses that can't be
resolved to hostnames.  Use D_PARSE instead.

mountd: fix netgroup lookup for short hostnames

2015-12-16T15:12:38+00:00

Commit 9a92ef6f to add netgroup lookup of resolvable
IP addresses inadvertently broke the netgroup
check for short hostnames.

This patch fixes that breakage by changing the IP address
lookup to use a separate variable.

exportfs: Restore the EAI_NONAME check in host_pton()

2015-11-02T13:55:04+00:00

Commit d89e3fc7 removed the EAI_NONAME check altogether instead of just
moving the NULL check.  This causes exportfs -u to incorrectly exit
with 1 whenever there's more than one MCL_FQDN export in the exportlist.
