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.

mountd: Replace "struct hostent" with "struct addrinfo"

2010-06-22T20:04:53+00:00

struct hostent can store either IPv4 or IPv6 addresses, but it can't
store both address families concurrently for the same host.  Neither
can hostent deal with parts of socket addresses that are outside of
the sin{,6}_addr field.

Replace the use of "struct hostent" everywhere in libexport.a, mountd,
and exportfs with "struct addrinfo".  This is a large change, but
there are so many strong dependencies on struct hostent that this
can't easily be broken into smaller pieces.

One benefit of this change is that hostent_dup() is no longer
required, since the results of getaddrinfo(3) are already dynamically
allocated.

Mountd should use separate lockfiles

2009-04-03T19:13:10+00:00

Mountd keeps file descriptors used for locks separate from
those used for io and seems to assume that the lock will
only be released on close of the file descriptor that was used
with fcntl.  Actually the lock is released when any file
descriptor for that file is closed.  When setexportent() is called
after xflock() he closes and reopens the io file descriptor and defeats the
lock.

This patch fixes that by using a separate file for locking, cleaning
them up when finished.

When a FQDN exists in /var/lib/nfs/rmtab it causes

the exportfs command to seg fault due to the nfs_export pointer
not being allocated. Reworking the parentheses in rmtab_read()
so the htype variable is evaluated correctly fix the problem.

rpc.mountd: make exportent->e_hostname a dynamically-allocated string

2007-09-28T01:39:56+00:00

This makes the e_hostname field of the exportent into a pointer to a
dynamically allocated string. This is necessary since this is field is
often filled out from the m_hostname. This too adds a few
micro-optimizations as we can avoid copying the string in some places
and simply pass a pointer to the original string instead.
