* Add pool state /proc entry, "SUSPENDED" poolsTony Hutter2018-06-0618-26/+383
| | | | | | | | | | | | | | | | | | | 1. Add a proc entry to display the pool's state: $ cat /proc/spl/kstat/zfs/tank/state ONLINE This is done without using the spa config locks, so it will never hang. 2. Fix 'zpool status' and 'zpool list -o health' output to print "SUSPENDED" instead of "ONLINE" for suspended pools.

* Remove rwlock wrappersBrian Behlendorf2018-06-044-137/+54
| | | | | | | | | | | | | | | | | | | The only remaining consumer of the rwlock compatibility wrappers is ztest. Remove the wrappers and convert the few remaining calls to the underlying pthread functions. rwlock_init() -> pthread_rwlock_init() rwlock_destroy() -> pthread_rwlock_destroy() rw_rdlock() -> pthread_rwlock_rdlock() rw_wrlock() -> pthread_rwlock_wrlock() rw_unlock() -> pthread_rwlock_unlock() Note pthread_rwlock_init() defaults to PTHREAD_PROCESS_PRIVATE which is equivilant to the USYNC_THREAD behavior. There is no functional change. Reviewed-by: Olaf Faaland <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #7591

No txg is currently being synced. 2] Immediately after the opening of B, txg_kick() was run by some other write (and because of A's dirty data) and saw that we are not currently syncing any txg and no one has requested quiescing so it requests one by bumping tx_quiesce_txg_waiting and broadcasts the quiesce thread. 3] The quiesce thread just passed txg A to be synced and sees that a quiescing request has been sent to it so it immediately grabs B without letting it gather enough data, putting it in a quiesced state and opening a new txg C. In this scenario txg B, is an example of how the entries of interest show up in the txg.d output. Ideally we would like txg_kick() to get triggered only when we are sure that we are not syncing AND not quiescing any txg. This way we can kick an open TXG to the quiescing state when we are sure that there is nothing going on and we would benefit from the different states running concurrently.

* OpenZFS 9245 - zfs-test failures: slog_013_pos and slog_014_posJohn Wren Kennedy2018-06-044-38/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | Test 13 would fail because of attempts to zpool destroy -f a pool that was still busy. Changed those calls to destroy_pool which does a retry loop, and the problem is no longer reproducible. Also removed some non functional code in the test which is why it was originally commented out by placing it after the call to log_pass. Test 14 would fail because sometimes the check for a degraded pool would complete before the pool had changed state. Changed the logic to check in a loop with a timeout and the problem is no longer reproducible.

* OpenZFS 9235 - rename zpool_rewind_policy_t to zpool_load_policy_tPavel Zakharov2018-06-049-84/+85
| | | | | | | | | | | | | | | | | | | | | | | We want to be able to pass various settings during import/open of a pool, which are not only related to rewind. Instead of adding a new policy and duplicate a bunch of code, we should just rename rewind_policy to a more generic term like load_policy. For instance, we'd like to set spa->spa_import_flags from the nvlist, rather from a flags parameter passed to spa_import as in some cases we want those flags not only for the import case, but also for the open case. One such flag could be ZFS_IMPORT_MISSING_LOG (as used in zdb) which would allow zfs to open a pool when logs are missing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel_read & kernel_write functions have always wrapped the vfs_read & vfs_write functions respectively. However, they could not be used by vn_rdwr() since the offset wasn't passed as a pointer. This prevented us from being able to properly update the file offset. Linux 4.14 unexported vfs_read & vfs_write but also changed the signature of kernel_read & kernel_write to provide the needed functionality. Use these updated functions when available.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | taskq_seq_show_impl walks the tq_active_list to show the tqent_func and tqent_arg. However for taskq_dispatch_ent, it's very likely that the task entry will be freed during the function call, and causes a use-after-free bug. To fix this, we duplicate the task entry to an on-stack struct, and assign it instead to tqt_task. This way, the tq_lock alone will guarantee its safety.
