[impact] When hosting an NFS share that is sharing the home directory of users (e.g. /home), doing an "ls -l" on a client that has access to this share will return permission denied errors for each user before showing the output of the command. Below is an example output of the current version of ls: ghadi@nfs-client:/mnt/nfs_clientshare$ ls -l ls: test_user1: Permission denied ls: test_user2: Permission denied total 12 drwxr-x--- 5 ghadi ghadi 4096 May 7 18:17 ghadi drwxr-x--- 2 1001 1001 4096 Jun 17 15:25 test_user1 drwxr-x--- 2 1002 1002 4096 Jun 17 15:27 test_user2 There has been a patch upstream to resolve this issue that I have already backported after some modifications to fit the current version of coreutils being used: https://cgit.git.savannah.gnu.org/cgit/coreutils.git/commit/?id=b58e321c8d5dd841f4170312692035a66b5ac149 [Test Plan] 1. On the NFS server create a few users and make sure they have a home directory: $ sudo useradd -m test_user1 $ sudo useradd -m test_user2 2. Then setup the NFS server and make sure to share /home 3. On the client machine, mount the NFS share and run "ls -l" 4. With the current version of coreutils you will see the following output: $ ghadi@nfs-client:/mnt/nfs_clientshare$ ls -l ls: test_user1: Permission denied ls: test_user2: Permission denied total 12 drwxr-x--- 5 ghadi ghadi 4096 May 7 18:17 ghadi drwxr-x--- 2 1001 1001 4096 Jun 17 15:25 test_user1 drwxr-x--- 2 1002 1002 4096 Jun 17 15:27 test_user2 However in the patched version you will see the following: $ ghadi@nfs-client:/mnt/nfs_clientshare$ ls -l total 12 drwxr-x--- 5 ghadi ghadi 4096 May 7 18:17 ghadi drwxr-x---? 2 1001 1001 4096 Jun 17 15:25 test_user1 drwxr-x---? 2 1002 1002 4096 Jun 17 15:27 test_user2 [Where problems could occur] * The patch adds "?" symbols when it cannot get the metadata which could cause issues with some scripts * Some errors that should be displayed might stop being displayed specially if they are related to reading file attributes (operations that involve the listxattr syscall) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/coreutils/+bug/2115274/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
