If for some reason the cleanup of dbwrap_watch_send does not work
properly, we might starve indefinitely. Make the lock routine more
robust by retrying every 5-10 seconds. g_lock_trylock will clean up
orphaned entries.

The acl element is changed to be a talloc child, and is no longer one element
longer than requested by virtue of the acl[1] base pointer.
This also avoids one of the few remaining cases of over-allocation of a structure.

This malloc() and free() actually shows up quite high on a call profile of

We don't resolve our own "Domain Local" groups since bug #7843 has been
fixed. So we need to add the add resource groups to the sid list too.
Before bug #7843 the "Domain Local" groups were added with a
lookupuseraliases call, but this isn't done anymore for our domain
so we need to resolve resource groups here.

as we need to keep the saved set uid/gid otherwise there is an
interaction with open[at]() and NO_ATIME returning EPERM. As this

We only set the real euid, not the effective one. This is not
a security issue as this is *only* used in the quota code, and
only between code that brackets it with save_re_uid()/restore_re_uid(),
Also this is not used on most platforms (we use USE_SETREUID by
preference) but it's better to have this right. Bug to follow to get this
fixed in 3.6.next and 3.5.next.

This matches the function's intention much closer, since it
also tests whether we have a valid local read only copy.
Pair-Programmed-With: Gregor Beck <gbeck@sernet.de>
The introduction of read only copies has broken the algorithm for
deteting whether we can use the local record copy for fetch_locked
and fetch: For fetch locked the new code always uses the local copy
if there is one...
This patch re-establish the original algorithm for the build against
a ctdb without read only record copies.

This helps clarify the role of this structure and wrapper function.
The purpose here is to provide helper functions to the lib/param
loadparm_context that point back at the s3 lp_ functions. This allows
a struct loadparm_context to be passed to any point in the code, and
always refer to the correct loadparm system. If this has not been
set, the variables loaded in the lib/param code will be returned.
As requested by Michael Adam.

The flags returned were TDB-specific: this was only used for detecting
the endianness of obsolete databases (the conversion code was put in in
2003, with reference to Samba 2.3).
It's easier to remove it than to translate the NTDB flags to TDB flags,
and it's a really weird thing to ask for anyway.

With this change, the define to check for AIO is HAVE_AIO, consistant
with other subsystems.
It is now also on by default in the autoconf build, as it has been for waf.
Andrew Bartlett
In order to support other bind methods, introduce a generic bind callback.
When smbldap_state.bind_callback is set, it means there is an alternative
way to perform LDAP bind to ldap_simple_bind_s() so call it instead.
The call is wrapped in become_root()/unbecome_root() to allow proper permissions
in smbd to access needed resources in the callback, for example, credential caches.
When run outside smbd, become_root()/unbecome_root() are no-op.
The API expectation is similar to ldap_simple_bind_s().
A caller of smbldap API can pass additional information to the callback by setting
smbldap_state.bind_callback_data pointer.
Both callback and the data pointer elements of smbldap_state structure get
cleaned up if someone sets proper credentials on smbldap_state with
smbldap_set_creds() so if you are interested in using smbldap_state.bind_dn
with the callback, make sure to set callback after credentials are set.
This makes it possible to print the entire string again.

This required that the lower level cache store a UID/GID and a type, and that
we operate on struct unixid rather than just uid/gid.
The ID_TYPE_BOTH is then handled as being a positive mapping for both
a UID and GID value. Wrapper functions are provided so that callers are not
changed in this patch.

This safely allocates the task_id so that when we have multiple event

This simplifies the g_lock implementation. The new implementation tries to
acquire a lock. If that fails due to a lock conflict, wait for the g_lock
record to change. Upon change, just try again. The old logic had to cope with
pending records and an ugly hack into ctdb itself. As a bonus, we now get a
really clean async g_lock_lock_send/recv that can asynchronously wait for a
global lock. This would have been almost impossible to do without the
dbwrap_record_watch infrastructure.
In this case, the blob is already in memory, so it is easier to return the full
blob to the caller, and let the caller decide if some interface restriction
stops the full blob from being passed all the way up the stack.
This allows us to quickly write a python wrapper for this xattr storage
mechanism.
Andrew Bartlett
This will allow db_open_tdb() to be called from common code, which may
already have a loadparm context loaded.
It also slowly moves the lp_ctx up the stack, as required to remove
the library loop between smbconf and the registry.
Andrew Bartlett
This will help notify torture tests: A tevent barrier can be waited on with
tevent_barrier_wait_send/recv. The barrier is initialized with a number of
requests that it will accept waiting. When that number is reached, all those
requests will be released and their callback will be called. The barrier will
be free for re-use again.
This is a void* that represents a signal handler attached to some
custom tevent_context. This is necessary to make the tdb based
messaging infrastructure trigger its business when we are sitting in
tevent_loop_once for an event context that is not the main one in the
messaging context.
This is designed to spread the load on individual ctdb records to allow upper
layers to do backoff mechanisms. In the ctdb case, do not get the record if a
local lock is already taken. If we are not dmaster, do at most one migrate
attempt.
For the tdb case, this is a nonblocking fetch_locked. If someone else has the
lock, give up.
This is a caching layer for the notify database and potentially for the brlock
database. It caches the parse_record operation as long as the underlying seqnum
does not change.
Now that we always require a 64 bit off_t, we no longer need SMB_OFF_T.
