* lib: Change the g_lock data modelVolker Lendecke2019-11-221-1/+1
| | | | | | | | | | | | | | | | | | | | Now we have one fixed field for the exclusive lock holder and an array of shared locks. This way we now prioritize writers over readers: If a pending write comes in while readers are active, it will put itself into the exclusive slot. Then it waits for the readers to vanish. Only when all readers are gone the exclusive lock request is granted. New readers will just look at the exclusive slot and see it's taken. They will then line up as watchers, retrying whenever things change. This also means that it will be cheaper to support many shared locks: Granting a shared lock just means to extend the array. We don't have to walk the array for possible conflicts. This also adds explicit UPGRADE and DOWNGRADE operations for better error checking.

* s3:notifyd: Handle sigup in notifyd to reparse smb.confShyamsunder Rathi2019-06-271-1/+23
| | | | | | | | | | | | | | | | | | | At present, SIGHUP is blocked on notifyd. So, if parent smbd is started with "log level" 10 in smb.conf, and later changed to 0, the SIGHUP will not change the log level to 0 in notify smbd process and it will keep printing verbose logs in the corresponding log files. Proposed fix is to write a SIGHUP handler for notifyd and set it to reload services.

* s3:cleanupd: use MSG_SMB_BRL_VALIDATE to signal cleanupd unclean process ↵Ralph Boehme2018-05-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | shutdown Since 6423ca4bf293cac5e2f84b1a37bb29b06b5c05ed messaging_send_all() broadcasts messages in a cluster, so cleanupd receives those broadcasts and acts upon it by re-broadcasting the message. Result: message storm. By reactivating the currently unused MSG_SMB_BRL_VALIDATE for the trigger message to cleanupd we avoid the storm. Note that MSG_SMB_BRL_VALIDATE was unused only in the sense that noone *listened* to it, but we were still *sending* the message in smbd_parent_ctdb_reconfigured(). de6fe2a1dd6ab03b1c369b61da17fded72305b2d removed listening for MSG_SMB_BRL_VALIDATE from cleanupd.

* smbd: Claim version in g_lockVolker Lendecke2017-06-151-0/+114
| | | | | | | | | | | | | | | Protect smbd against version incompatibilities in a cluster. At first startup smbd locks "samba_version_string" and writes its version string. It then downgrades the lock to a read lock. Subsequent smbds check against the version string and also keep the read lock around. If the version does not match, we try to write our own version. But as there's a read lock, the lock upgrade to write lock will fail due the read lock being around. So as long as there's one smbd with this read lock, no other version of smbd will be able to start. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>
