** Description changed: + [Impact] + For Bionic release, current cifs-utils package version is 6.8-1. This version is missing below two commits https://git.samba.org/?p=cifs-utils.git;a=commit;h=74a1ced5f706ea6a9cab885693c7755657b81a2a https://git.samba.org/?p=cifs-utils.git;a=commit;h=6df98da5cd3fbb33f6f535c6784f037bbadadb84 - [Impact] - * Without above feature, we won’t be able to analyze most part of - network traces on a client side in case customers have problems - accessing Azure Files service from VMs running Ubuntu Bionic. + * Without above feature, we won’t be able to analyze most part of network traces on a client side in case customers have problems accessing Azure Files service from VMs running Ubuntu Bionic. + + [Test Case] + Setup a windows vm to share a directory and an ubuntu host with cifs-utils installed. + + # mount -v -t cifs //<widnows-IP>/<windows-share>/ /path/to/mount -o + username=<username>,password=<password>,domain=<domain>,seal,vers=3.0 + + Once the share is mounted successfully, we can manually test the various commands available in smbinfo utility. + The syntax is : + # smbinfo <command> <file> + + For the available smbinfo commands : + # smbinfo -h + + For example : + + # smbinfo keys joalif.txt + SMB3.0 CCM encryption + Session Id: 69 00 00 1c 00 18 00 00 + Session Key: d7 a5 b3 11 06 a0 3b 94 6a 52 3a 01 98 73 6b d3 + Server Encryption Key: 9d eb 4c 89 28 62 39 66 a9 e0 0d 57 b9 33 30 40 + Server Decryption Key: e6 9a a9 46 c1 a4 7b 6c 3d 2b 18 54 b4 93 a2 42 + + + [Regression Potential] + + These patches cherry pick and touch 2 files : smbinfo.c and smbinfo.rst. + They add the smbinfo utility which is required for the 2 commits mentioned in the <Impact> section. Since smbinfo does not interact with the rest of the code any regression potential would involve smbinfo itself. + + [Other] + + The smbinfo utility to work properly requires kernel >5.0 and the + 'keys' command which is the one used for dumping session id, encryption + and decryption keys requires kernel > 5.4.
