Description of problem: A patch between 8.5 and 8.6 kernels broke some nfs mount options, such as 'noresvport' Version-Release number of selected component (if applicable): kernel-4.18.0-372* (all kernels beginning with kernel-4.18.0-356.el8~13^2~30) How reproducible: easy, see steps below Steps to Reproduce: # mount server:/export /mnt -onoresvport # netstat -anpt | grep -w 2049 Actual results: source TCP port is still in the 'reserved' port range Expected results: source TCP port is 1024+ Additional info: this became broken with the following commit in the RHEL 8.6 kernel: cf2c7c1aa904 NFSv4: Initialise connection to the server in nfs4_alloc_client() this is fixed with this upstream commit: commit 468d126dab45718feeb728319be20bd869a5eaa7 Author: Trond Myklebust <trond.myklebust> Date: 2022-02-02 18:52:01 -0500 NFS: Fix initialisation of nfs_client cl_flags field For some long forgotten reason, the nfs_client cl_flags field is initialised in nfs_get_client() instead of being initialised at allocation time. This quirk was harmless until we moved the call to nfs_create_rpc_client().
