321c51e14a s3:winbind: Move functions to enable or disable cache to winbindd-lib subsystem
The source3/winbindd/winbindd.c file does not belong to 'winbindd-lib'
subsystem. Funtions called from winbindd-lib must be part of it.

00ea654961 s3:winbind: Convert wcache_opnum_cacheable() to a whitelist
It avoids having to explicitly blacklist new DCE/RPC calls.

This is the current list of non cacheable calls:

NDR_WBINT_PING
NDR_WBINT_QUERYSEQUENCENUMBER
NDR_WBINT_ALLOCATEUID
NDR_WBINT_ALLOCATEGID
NDR_WBINT_CHECKMACHINEACCOUNT
NDR_WBINT_CHANGEMACHINEACCOUNT
NDR_WBINT_PINGDC
NDR_WBINT_LISTTRUSTEDDOMAINS

It includes the ListTrustedDomains call recently converted to a local

8dfdbe095a winbindd: don't set mapped_state in winbindd_dual_auth_passdb()
mapped_state is a special hack for authenticate_ldap_simple_bind_send()
in order to avoid some additional work in authsam_check_password_internals()

This doesn't apply here. We should also handle wbinfo -a
authentication UPN names, e.g. administrator@DOMAIN,
even if the account belongs to the local sam.

With this change the behavior is consistent also locally on DCs and
also an RODC can handle these requests locally for cached accounts.

d05b5366a6 s3:winbind: Remove list_all_domains condition always false
The 'list_all_domains' flag in a winbind request is only set by the
torture_winbind_struct_list_trustdom() test, in fact to check the flag
is ignored.

The WINBINDD_LIST_TRUSTDOM command received by winbind parent is handled
by winbindd_list_trusted_domains() which fills the response from the
cached domain list and does not handle the flag.

The WINBINDD_LIST_TRUSTDOM command sent from the parent to the domain
childs when the rescan timer expires do not set this flag, so this
commit removes the code handling it in the child.

b92589c31f s3:winbindd: Fix winbindd child logfile name handling
BUG: https://bugzilla.samba.org/show_bug.cgi?id=14852

Handling of logfile name for main and child winbindd must ensure:

1) Log directory is selected in this order:
  * -l option of winbindd
  * "log file" parameter in smb.conf
  * compile time value '/usr/local/samba/var'

2) Log filename pattern
  * parent process uses log.winbindd
  * child uses log.wb-<name>

3) Log reopen works for both parent and child (i.e. log filename is not changed)
  * kill -HUP <pid>
  * smbcontrol <pid> reload-config

This commit removes 3 calls of is_default_dyn_LOGFILEBASE() to make sure that:
  - 1st removal: child uses log.wb-<name> after the fork
  - 2nd removal: child after HUP signal, does not switch to log.winbindd
  - 3rd removal: child after smbcontrol reload-config, does not switch to
    log.winbindd

af06d73a75 s3:rpc_server: Do not use the default ncalrpc endpoint for external services
In samba3 it is possible to run some services externally, for example:

rpc_daemon:lsasd = fork
rpc_server:netlogon = disabled
rpc_server:samr = external
rpc_server:lsarpc = external

The external services running in separate processes have to use its own
dedicated ncalrpc endpoint, otherwise will race with main smbd serving the
embedded services to accept connections on ncalrpc default socket. If the
connection ends in an external process and the client tries to bind to an
interface not registered there (like winreg for example) the bind will fail.

93bac5f122 winbindd_pam: add NT4 DC handling into winbind_samlogon_retry_loop()
Handle the case where a NT4 DC does not fill in the acct_flags in
the samlogon reply info3. Yes, in 2021, there are still admins
arround with real NT4 DCs.

NT4 DCs reject authentication with workstation accounts with
NT_STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT, even if
MSV1_0_ALLOW_WORKSTATION_TRUST_ACCOUNT is specified.

We no longer call dcerpc_samr_QueryUserInfo(level=16)
to get the acct_flags, as we only ever got
ACB_NORMAL back (maybe with ACB_PWNOEXP in addition),
which is easy to calculate on our own.
This was removed in commit (for 4.15.0rc1):

      winbind: remove legacy flags fallback

      Some very old NT4 DCs might have not returned the account flags filled in. This
      shouldn't be a problem anymore. Additionally, on a typical domain member server,
      this request is (and can only be) send to the primary domain, so this will not
      work with accounts from trusted domains.

It means one more caller of the problematic cm_connect_sam()
function is removed! SAMR connections may not be allowed for
machine accounts with modern AD DCs.

For network logons NT4 DCs also skip the
account_name, so we have to fallback to the
one given by the client. We have code to cope
with that deeply hidden inside of netsamlogon_cache_store().

Up to Samba 4.7 netsamlogon_cache_store() operated on the
info3 structure that was passed to the caller of winbind_dual_SamLogon()
and pass propagated up to auth_winbind in smbd.

But for Samba 4.8 the following commit:

actually changed the situation and only a temporary info3 structure
was passed into netsamlogon_cache_store(), which means
account_name was NULL and get propagated as "" into auth_winbind
in smbd, where getpwnam() is no longer possible and every
smb access gets NT_STATUS_LOGON_FAILURE.

9b2c17e57a s3:winbindd: Simplfy sequence number caching
The sequence number is used to detect if the cache is still valid. It
expires when the `winbind cache time` is over. After that time we want
to fetch new information from a DC to make sure we are up to date.

If a DC goes down and we recreate the connection, we want to expire the
caches sooner. So we reset the sequence number and the next call should
refill the caches.

Using the current time as the sequence number is more reliable, as the
sequence number of two DCs could in theory be equal. All we have to do
is to make sure we reset it after we reconnect to a DC.

Previously the sequence number check was based on the AD database change
sequence number. Now this is based on a current time value which gets
reset after a successful (re)connect.

will return NT_STATUS_RPC_INTERFACE_NOT_FOUND if the interface is not
registered in the calling process. This causes a noisy error message in
winbind when it tries to open the dssetup pipe to the primary domain and
it is not an AD domain.

The callers of wb_open_internal_pipe() when connecting to the domain
already logs the error at level greather or equal to five. This commit
moves the dupplicated and noisy error message at level zero from
wb_open_internal_pipe() to its callers outside winbindd_cm.c.

This error can be seen in winbindd logs of ad_member and nt4_member test
environments.

309c81e7e2 daemons: Do not notify systemd in child processes started by main samba
When samba runs as ADDC only the main 'samba' daemon have to notify
its status to systemd because our systemd unit files contains implied
NotifyAccess=main since commit d1740fb3d5.

This commit adds a function to disable the systemd notification in the
smbd and winbinddd child processes started by the main 'samba' daemon in
AD DC mode to avoid warnings like:

systemd[1]: samba-ad-dc.service: Got notification message from PID 26194,
	    but reception only permitted for main PID 26187

d8339056ee s3:idmap_hash: reliable return ID_TYPE_BOTH
idmap_hash used to bounce back the requested type,
which was ID_TYPE_UID, ID_TYPE_GID or ID_TYPE_NOT_SPECIFIED
before as the winbindd parent always used a lookupsids.
When the lookupsids failed because of an unknown domain,
the idmap child weren't requested at all and the caller
sees ID_TYPE_NOT_SPECIFIED.

This module should have supported ID_TYPE_BOTH since
samba-4.1.0, similar to idmap_rid and idmap_autorid.

Now that the winbindd parent will pass ID_TYPE_BOTH in order to
indicate that the domain exists, it's better to always return
ID_TYPE_BOTH instead of a random mix of ID_TYPE_UID, ID_TYPE_GID
or ID_TYPE_BOTH. In order to request a type_hint it will return
ID_REQUIRE_TYPE for ID_TYPE_NOT_SPECIFIED, which means that
the parent at least assures that the domain sid exists.
And the caller still gets ID_TYPE_NOT_SPECIFIED if the
domain doesn't exist.

3e27dc4847 daemons: report status to systemd even when running in foreground
When systemd launches samba services, the configuration we have in
systemd service files expects that the main process (/usr/sbin/*)
would use sd_notify() to report back its status. However, we only use
sd_notify() when running become_daemon().

As a result, samba/smbd/winbindd/nmbd processes never report back its
status and the status updates from other childs (smbd, winbindd, etc)
are not accepted as we now have implied NotifyAccess=main since commit
d1740fb3d5

This leads to a timeout and killing samba process by systemd. Situation
is reproducible in Fedora 33, for example.

Make sure that we have required status updates for all daemons in case
we aren't runnning in interactive mode.

It's also possible to accept kerberos authentication without reaching

d42aaeba6e wb_sids2xids: call wb_parent_idmap_setup_send/recv as the first step
This isn't really used yet, but it will in the next commits.

Also idmap_child_handle() will soon assert that
wb_parent_idmap_setup_send/recv() was called before it's used.

209e81a2ea winbindd: add generic wb_parent_idmap_setup_send/recv() helpers
This is more or less a copy of wb_xids2sids_init_dom_maps_send/recv,
but it's more generic and doesn't imply global state.

It also closes a initialization race by using a tevent_queue to
serialize the calls.

In the next commits we'll replace wb_xids2sids_init_dom_maps_send/recv.

We'll also use the new function in the wb_sids2xids code.

Source code in winbind_rpc.c states that if the trusted domain
has no SID, winbindd just aborts the session. This happens with
MIT Kerberos realm added as trust to AD and winbindd just returns
without processing further as there is no SID returned for the
Linux system having kerberos support.

This fix makes winbindd to skip the domain having NULL SID instead
of aborting the request completely.

When winbindd is asked to map a name like realm.com\name to a SID ,that
is sucessfully resolved through the lsa lookup name call. The same call
also returns the short domain name (netbios name of the domain). Use
that short domain name for the sid_to_name cache entry, so that
subsequent sid_to_name queries return the expected netbiosname\name
result and not realm.com\name.

62f54229fc winbindd: track whether a result from xid2sid was coming from the cache
This is needed in preparation of moving the step to update the idmap
cache from the per-idmap-domain callback wb_xids2sids_dom_done() to the
top-level callback wb_xids2sids_done().

Currently the sequence of action is:

* check cache, if not found:
  * ask backends
  * cache result from backend
* return results

Iow, if we got something from the cache, we don't write the cache.

The next commit defers updating the cache to the top-level callback, so
the sequence becomes

* check cache, if not found:
  * ask backends
* cache results
* return results

This has two problems:

* it needlessly writes to the cache what we just got from it

* it possibly overwrites the ID_TYPE_BOTH for a SID-to-xid mapping in
  the following case:

  - existing ID_TYPE_BOTH mapping in the cache, eg:

    IDMAP/SID2XID/S-1-5-21-2180672342-2513613279-2566592647-512 -> Value: 3000000:B

  - someone calls wb_xids2sids_send() with xid.id=3000000,xid.type=ID_TYPE_GID

  - cache lookup with idmap_cache_find_gid2sid() succeeds

  - when caching results we'd call idmap_cache_set_sid2unixid() with the
    callers xid.type=ID_TYPE_GID, so idmap_cache_set_sid2unixid() will
    overwrite the SID-to-xid mapping with ID_TYPE_GID

f5a8bc2f94 winbindd: make a copy of xid's in wb_xids2sids_send()
This is in preparation of setting the result of the mapping in the top-
level callback wb_xids2sids_done(), not in the per-idmap-domain callback
wb_xids2sids_dom_done().

When caching the mapping we need the id-type from the backend, so we
need a way to pass up that information from wb_xids2sids_dom_done() up
to wb_xids2sids_done()

The xids array copy gets passed from wb_xids2sids_send() to
wb_xids2sids_dom_send(), so wb_xids2sids_dom_done() can then directly
update the top-level copy.

8b8d9fdad4 winbindd: Route predefined domains through the BUILTIN domain child
Without this eg "NT Authority" didn't work:

  $ bin/wbinfo -n "NT Authority/Authenticated Users"
  failed to call wbcLookupName: WBC_ERR_DOMAIN_NOT_FOUND
  Could not lookup name NT Authority/Authenticated Users

  $ bin/wbinfo --group-info="NT Authority/Authenticated Users"
  failed to call wbcGetgrnam: WBC_ERR_DOMAIN_NOT_FOUND
  Could not get info for group NT Authority/Authenticated Users

With the patch:

  $ bin/wbinfo -n "NT Authority/Authenticated Users"
  S-1-5-11 SID_WKN_GROUP (5)

  $ bin/wbinfo --group-info="NT Authority/Authenticated Users"
  NT AUTHORITY\authenticated users10002:
