Subject: [lustre-devel] [PATCH 14/18] lustre: quota: nodemap squashed root cannot bypass quota
Date: Mon, 19 Jul 2021 08:32:09 -0400 [thread overview]
Message-ID: <1626697933-6971-15-git-send-email-jsimmons@infradead.org> (raw)
In-Reply-To: <1626697933-6971-1-git-send-email-jsimmons@infradead.org>
From: Sebastien Buisson <sbuisson@ddn.com>
When root on client is squashed via a nodemap's squash_uid/squash_gid,
its IOs must not bypass quota enforcement as it normally does without
squashing.
So on client side, do not set OBD_BRW_FROM_GRANT for every page being
used by root. And on server side, check if root is squashed via a
nodemap and remove OBD_BRW_NOQUOTA.
WC-bug-id: https://jira.whamcloud.com/browse/LU-14739
