I haven't tested it as I don't use quotas, but look at the relevant XFS code:
if (restricted_chown && (iuid != uid || (igid != gid && !in_group_p((gid_t)gid))) && !capable(CAP_CHOWN)) { code = XFS_ERROR(EPERM); goto error_return; } /* * Do a quota reservation only if uid or gid is actually * going to change. */ if ((XFS_IS_UQUOTA_ON(mp) && iuid != uid) || (XFS_IS_GQUOTA_ON(mp) && igid != gid)) { ASSERT(tp); code = XFS_QM_DQVOPCHOWNRESV(mp, tp, ip, udqp, gdqp, capable(CAP_FOWNER) ? XFS_QMOPT_FORCE_RES : 0); if (code) /* out of quota */ goto error_return; } So if restricted_chown is not in effect and the uid/gid change, the quota ownership will be shifted to the new uid/gid. > touch /tmp/breaking.alice.quota > chmod 666 /tmp/breaking.alice.quota > fakeroot chown alice /tmp/breaking.alice.quota > cat < /dev/zero > /tmp/breaking.alice.quota it would seem it really is possible.
