Bug Description

[Impact]

* In b49151d684f44 tx_waited has been renamed to tx_dirty_delayed, but
only in the tracepoint definition (in trace_dmu.h) and not in the rest
of the code, causing build errors if zfs tracepoints are enabled.

* Fix by reverting tx_dirty_delayed back to the original name tx_waited

NOTE: this bug doesn't show up in regular kernel builds, because zfs tracepoints are not enabled by default, it is possible to see this problem only by enabling them and recompiling zfs outside our regular build process, but it's a good cleanup anyway (in case we need to enable zfs tracepoints in the future).

[Test Case]

* enable zfs tracepoints in config and build zfs

[Fix]

* Restore the old struct name to fix the build bug

[Regression Potential]

* It is a very small fix (just a rename of a struct member), so regression potential is minimal

[Original bug report]

I tried to build a kernel 4.15.0-48.51 that cloned from the Ubuntu kernel git (x86_64-generic flavour).

commit c50532b9d7b623ff98aeaf0b848e58adae54ca75 (HEAD -> master, tag: Ubuntu-4.15.0-48.51, origin/master, origin/HEAD)

1. Build a kernel image with 'zfs_enable' flag set as false.
2. Build SPL/ZFS modules independently by 'make' command (debug purpose; DECLARE_EVENT_CLASS() enabled).

But 'make' was always failed at the same point, 'zfs/module/zfs/trace.c' (as seem as below).

I tried to debug this issue with myself and found something intriguing.
In 'zfs/include/sys/trace_dmu.h', the failed code accessing 'tx_dirty_delayed' from 'dmu_tx_t' (which same as 'struct dmu_tx').

DECLARE_EVENT_CLASS(zfs_delay_mintime_class,
        TP_PROTO(dmu_tx_t *tx, uint64_t dirty, uint64_t min_tx_time),
        TP_ARGS(tx, dirty, min_tx_time),
        TP_STRUCT__entry(
            __field(uint64_t, tx_txg)
            __field(uint64_t, tx_lastsnap_txg)
            __field(uint64_t, tx_lasttried_txg)
            __field(boolean_t, tx_anyobj)
            __field(boolean_t, tx_dirty_delayed)
            __field(hrtime_t, tx_start)
            __field(boolean_t, tx_wait_dirty)
            __field(int, tx_err)
            __field(uint64_t, min_tx_time)
            __field(uint64_t, dirty)
        ),
        TP_fast_assign(
            __entry->tx_txg = tx->tx_txg;
            __entry->tx_lastsnap_txg = tx->tx_lastsnap_txg;
            __entry->tx_lasttried_txg = tx->tx_lasttried_txg;
            __entry->tx_anyobj = tx->tx_anyobj;
            __entry->tx_dirty_delayed = tx->tx_dirty_delayed;
            __entry->tx_start = tx->tx_start;
            __entry->tx_wait_dirty = tx->tx_wait_dirty;
            __entry->tx_err = tx->tx_err;
            __entry->dirty = dirty;
            __entry->min_tx_time = min_tx_time;
        ),
        TP_printk("tx { txg %llu lastsnap_txg %llu tx_lasttried_txg %llu "
            "anyobj %d dirty_delayed %d start %llu wait_dirty %d err %i "
            "} dirty %llu min_tx_time %llu",
            __entry->tx_txg, __entry->tx_lastsnap_txg,
            __entry->tx_lasttried_txg, __entry->tx_anyobj,
            __entry->tx_dirty_delayed, __entry->tx_start,
            __entry->tx_wait_dirty, __entry->tx_err,
            __entry->dirty, __entry->min_tx_time)
);

But, implementation of 'strcut dmu_tx' doesn't contain 'tx_dirty_delayed' (in zfs/include/sys/dmu_tx.h)

struct dmu_tx {
        /*
         * No synchronization is needed because a tx can only be handled
         * by one thread.
         */
        list_t tx_holds; /* list of dmu_tx_hold_t */
        objset_t *tx_objset;
        struct dsl_dir *tx_dir;
        struct dsl_pool *tx_pool;
        uint64_t tx_txg;
        uint64_t tx_lastsnap_txg;
        uint64_t tx_lasttried_txg;
        txg_handle_t tx_txgh;
        void *tx_tempreserve_cookie;
        struct dmu_tx_hold *tx_needassign_txh;

/* list of dmu_tx_callback_t on this dmu_tx */
list_t tx_callbacks;

/* placeholder for syncing context, doesn't need specific holds */
boolean_t tx_anyobj;

/* has this transaction already been delayed? */
boolean_t tx_waited;

/* transaction is marked as being a "net free" of space */
boolean_t tx_netfree;

/* time this transaction was created */
hrtime_t tx_start;

/* need to wait for sufficient dirty space */
boolean_t tx_wait_dirty;

int tx_err;
};

Looks above, current in-source-tree ZFS module seems not valid... :(
Are there any workarounds for this problem?

zfs-fix-build-error-with-tracepoints-enabled.patch Edit (2.1 KiB, text/plain)

Hi Hyeonho, good catch. It looks like b49151d684f44 renamed tx_waited to tx_dirty_delayed, but only in the tracepoint definition in trace_dmu.h and not in the rest of the code. I think we should simply restore the original name.

Can you check if this patch solves the problem? Thanks.

Hi, Andrea, thanks for your prompt response.
I tried to build kernel sources applied your patch, and it failed with an error.

/home/np/linux-4.15/zfs/include/sys/trace_dmu.h:65:33: error: ‘dmu_tx_t {aka struct dmu_tx}’ has no member named ‘waited’; did you mean ‘tx_waited’?
__entry->tx_waited = tx->waited;

According to the error message, the following diff caused the problem.

@@ -62,7 +62,7 @@ DECLARE_EVENT_CLASS(zfs_delay_mintime_class,
      __entry->tx_lastsnap_txg = tx->tx_lastsnap_txg;

      __entry->tx_anyobj = tx->tx_anyobj;
- __entry->tx_dirty_delayed = tx->tx_dirty_delayed;
+ __entry->tx_waited = tx->waited;

I think we should assign '__entry->tx_waited' as 'tx->tx_waited', not 'tx->waited'.

This bug was fixed in the package zfs-linux - 0.7.5-1ubuntu16.6

---------------
zfs-linux (0.7.5-1ubuntu16.6) bionic; urgency=medium

  * Fix hung z_zvol tasks during 'zfs receive' (LP: #1772412)
    - Adds a dedicated, per-pool, prefetch taskq to prevent the traverse
      code from monopolizing the global (and limited) system_taskq by
      inappropriately scheduling long running tasks on it. This fixes
      z_zvol hung tasks.

zfs-linux (0.7.5-1ubuntu16.5) bionic; urgency=medium

  * Fix build error with tracepoints enabled (LP: #1828763)
    - In b49151d684f44 (bionic kernel master-next branch) tx_waited has been
      renamed to tx_dirty_delayed, but only in the tracepoint definition (in
      trace_dmu.h) and not in the rest of the code, causing build errors if
      zfs tracepoints are enabled; fix by reverting tx_dirty_delayed back to
      the original name tx_waited.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
