Hey Trond, Anna, The following patches should be CC’d to stable for all stable branches with flexfiles. They fix an issue where the client can use the wrong credential if the server returns a read-only and readwrite layout with different creds. The client then goes into a LAYOUTRETURN/LAYOUTGET loop that it never recovers from. This has been seen in recent fedora releases. Here are the relevant patches: commit 3064b6861d00b7124558cdf79f9387f948361be3 Author: Jeff Layton <jlayton@xxxxxxxxxxxxxxx> Date: Thu Apr 21 20:52:00 2016 -0400 nfs: have flexfiles mirror keep creds for both ro and rw layouts commit 90a0be00e9d29d9baac27c0c63a5e71ca1334001 Author: Jeff Layton <jlayton@xxxxxxxxxxxxxxx> Date: Thu Apr 21 20:51:59 2016 -0400 nfs: get a reference to the credential in ff_layout_alloc_lseg commit 57f3f4c0cd50e90aa92eec20d9c309dd67c594a5 Author: Jeff Layton <jlayton@xxxxxxxxxxxxxxx> Date: Thu Apr 21 20:51:58 2016 -0400 nfs: have ff_layout_get_ds_cred take a reference to the cred commit 547a637630c61b9e1dae9abce2b44ce7076244af Author: Jeff Layton <jlayton@xxxxxxxxxxxxxxx> Date: Thu Apr 21 20:51:57 2016 -0400 nfs: don't call nfs4_ff_layout_prepare_ds from ff_layout_get_ds_cred -dros -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
