From: Zhang Xianwei Date: Wed, 27 Jul 2022 10:01:07 +0000 (+0800) Subject: NFSv4.1: RECLAIM_COMPLETE must handle EACCES X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7e5787469419519d8c06034240d818f385c09ea0;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git NFSv4.1: RECLAIM_COMPLETE must handle EACCES commit e35a5e782f67ed76a65ad0f23a484444a95f000f upstream. A client should be able to handle getting an EACCES error while doing a mount operation to reclaim state due to NFS4CLNT_RECLAIM_REBOOT being set. If the server returns RPC_AUTH_BADCRED because authentication failed when we execute "exportfs -au", then RECLAIM_COMPLETE will go a wrong way. After mount succeeds, all OPEN call will fail due to an NFS4ERR_GRACE error being returned. This patch is to fix it by resending a RPC request.
