Please pull the following changes since commit 2c85ebc57b3e1817b6ce1a6b703928e113a90442: Linux 5.10 (2020-12-13 14:41:30 -0800) are available in the Git repository at: git://git.samba.org/sfrench/cifs-2.6.git tags/5.11-rc-smb3 for you to fetch changes up to afee4410bc6c50e1422c5a45d633ad0e478ea960: cifs: update internal module version number (2020-12-16 21:56:42 -0600) ---------------------------------------------------------------- cifs/smb3 changes: the largest part are for support of the newer mount API which has been needed for cifs/smb3 mounts for a long time due to the new API's better handling of remount, and better error reporting. There are three additional small cleanup patches for this being tested, that are not included yet. This series also includes addition of support for the SMB3 witness protocol which can provide important notifications from the server to client on server address or export or network changes. This can be useful for example in order to be notified before the failure - when a server's IP address changes (in the future it will allow us to support server notifications of when a share is moved). It also includes three patches for stable e.g. some that better handle some confusing error messages during session establishment. Testing results: http://smb3-test-rhel-75.southcentralus.cloudapp.azure.com/#/builders/2/builds/462 There are three small patches from Dan Carpenter and also some unrelated (ie unrelated to this PR) multichannel and GCM256 (SMB3 encryption) fixes that are being investigated that are not included in this PR but I hope to finish off reasonably soon. Note that this series has a trivial merge conflict with a recent treewide change which Stephen Rothwell resolved in linux-next with a small patch: [PATCH] fixup for "treewide: rename nla_strlcpy to nla_strscpy." If you need me to send that or add it to my tree let me know. ---------------------------------------------------------------- Dmitry Osipenko (1): cifs: Add missing sentinel to smb3_fs_parameters Gustavo A.
