RHBA-2020:4403 - Bug Fix Advisory

Topic

An update for samba is now available for Red Hat Gluster Storage 3.5 on Red Hat Enterprise Linux 8.

Description

Samba is an open-source implementation of the Server Message Block (SMB) protocol and the related Common Internet File System (CIFS) protocol, which allows PC-compatible machines to share files, printers, and various information.

The Samba packages have been upgraded to upstream version 4.12.6, which provides a number of bug fixes and enhancements over the previous version.

This advisory fixes the following bugs:

• Previously, NMB deamon was uninitialized within 50.samba legacy event script. Due to this, even if the CTDB service was restarted, it failed to start the NMB deamon. With this update, NMB service related parts were separated into the new 48.netbios event script with CTDB_SERVICE_NMB initialized as "nmb" (enabled via "ctdb event script enable legacy 48.netbios").Now, restarting CTDB service brings up NMB daemon provided 48.netbios legacy script is enabled. (BZ#1558690)
• Earlier, on standalone Samba installations without identical "netbios name" in smb.conf, individual account databases per cluster node were created. Hence, authorization failures could occur as the account database was not shared among all cluster nodes. With this update, a unified default "netbios name" on all cluster nodes guarantees the account database is using identical credentials on all cluster nodes and the authorization works as expected. (BZ#1819797)

Users of Samba with Red Hat Gluster Storage are advised to upgrade to these updated packages.
