Create a hierarchy of datasets. 30# 2. Take a snapshot of the final child dataset and send it to a file. 31# 3. Use DTrace to run the zfs recv command and simultaneously monitor the 32# zc_name member of the zfs_cmd_t structure that is validated in 33# zfs_secpolicy_recv. 34# 4. Verify that the zc_name member is the parent dataset, as expected. 35# 36 37verify_runnable "both" 38 39function cleanup 40{ 41 destroy_dataset $TESTPOOL/testfs2 "-r" 42 destroy_dataset $TESTPOOL/testfs1 "-r" 43 [[ -f $sendfile ]] && log_must rm $sendfile 44} 45log_onexit cleanup 46 47log_assert "Verify zfs_secpolicy_recv is passed the proper trimmed name" 48 49typeset sendfile=$TESTDIR/sendfile 50 51log_must zfs create $TESTPOOL/testfs1 52log_must zfs create $TESTPOOL/testfs1/data 53log_must zfs create $TESTPOOL/testfs1/data/foo 54 55log_must zfs create $TESTPOOL/testfs2 56log_must zfs create $TESTPOOL/testfs2/data 57 58log_must mkfile 4k /$TESTPOOL/testfs1/data/foo/testfile0 59 60log_must zfs snap $TESTPOOL/testfs1/data/foo@1 61 62log_must eval "zfs send $TESTPOOL/testfs1/data/foo@1 > $sendfile" 63 64zc_name=$(/usr/sbin/dtrace -q -n \ 65 'fbt::zfs_secpolicy_recv:entry {printf("%s", stringof(args[0]->zc_name));}' \ 66 -c "zfs receive $TESTPOOL/testfs2/data/foo" < $sendfile) 67 68[[ "$zc_name" == "$TESTPOOL/testfs2/data" ]] || \ 69 log_fail "zc_name mismatch: $zc_name != $TESTPOOL/testfs2/data" 70 71log_pass "zfs_secpolicy_recv is passed the proper trimmed name" 72
