| | | | | | | | | | | | | This is arguably a change for internal consistency within OpenZFS, as the Linux implementation will reject read(2) on directories with EISDIR. It's not unreasonable for read(2) to do something here on FreeBSD, but we don't currently copy out anything useful anyways so start rejecting it with the appropriate error.

* Fix error handling in receive_writer_thread()Matthew Ahrens2020-05-141-1/+2
| | | | | | | | | | | | | | | | | | | | | | If `receive_writer_thread()` gets an error from `receive_process_record()`, it should be saved in `rwa->err` so that we will stop processing records, and the main thread will notice that the receive has failed. When an error is first encountered, this happens correctly. However, if there are more records to dequeue, the next time through the loop we will reset `rwa->err` to zero, allowing us to try to process the following record (2 after the failed record). Depending on what types of records remain, we may incorrectly complete the receive "successfully", but without actually having processed all the records. The fix is to only set `rwa->err` if we got a *non-zero* error. This bug was introduced by #10099 "Improve zfs receive performance by batching writes".

| | | | | | | | | | | | | | | | Commit fc551d7 introduced the wrappers abd_enter_critical() and abd_exit_critical() to mark critical sections.

* Resilver restarts unnecessarily when it encounters errorsJohn Poduska2020-05-136-4/+149
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When a resilver finishes, vdev_dtl_reassess is called to hopefully excise DTL_MISSING (amongst other things). If there are errors during the resilver, they are tracked in DTL_SCRUB, as spelled out in the block comment in vdev.c. DTL_SCRUB is in-core only, so it can only be used if the pool was online for the whole resilver. This state is tracked with the spa_scrub_started flag, which only gets set when the scan is initialized. Unfortunately, this flag gets cleared right before vdev_dtl_reassess gets called, so if there are any errors during the scan, DTL_MISSING will never get excised and the resilver will just continually restart. This fix simply moves clearing that flag until after the call to vdev_dtl_reasses. In addition, if a pool is imported and already has scn_errors > 0, this change will restart the resilver immediately instead of doing the rest of the scan and then restarting it from the beginning. On the other hand, if scn_errors == 0 at import, then no errors have been encountered so far, so the spa_scrub_started flag can be safely set. A test has been added to verify that resilver does not restart when relevant DTL's are available.

* Improvements on persistent L2ARCGeorge Amanakis2020-05-075-126/+278
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Functional changes: We implement refcounts of log blocks and their aligned size on the cache device along with two corresponding arcstats. The refcounts are reflected in the header of the device and provide valuable information as to whether log blocks are accounted for correctly. These are dynamically adjusted as log blocks are committed/evicted. zdb also uses this information in the device header and compares it to the corresponding values as reported by dump_l2arc_log_blocks() which emulates l2arc_rebuild(). If the refcounts saved in the device header report higher values, zdb exits with an error. For this feature to work correctly there should be no active writes on the device. This is also employed in the tests of persistent L2ARC. We extend the structure of the cache device header by adding the two new variables mirroring the refcounts after the existing variables to preserve backward compatibility in terms of persistent L2ARC. 1) a new arcstat "l2_log_blk_asize" and refcount "l2ad_lb_asize" which reflect the total aligned size of log blocks on the device. This is also reflected in the header of the cache device as "dh_lb_asize". 2) a new arcstat "l2arc_log_blk_count" and refcount "l2ad_lb_count" which reflect the total number of L2ARC log blocks present on cache devices. It is also reflected in the header of the cache device as "dh_lb_count". In l2arc_rebuild_vdev() if the amount of committed log entries in a log block is 0 and the device header is valid we update the device header. This will facilitate trimming of the whole device in this case when TRIM for L2ARC is implemented. Improve loop protection in l2arc_rebuild() by using the starting offset of the payload of each log block instead of the starting offset of the log block. If the zio in l2arc_write_buffers() fails, restore the lbps array in the header of the device to its previous state in l2arc_write_done(). If l2arc_rebuild() ends the rebuild process without restoring any L2ARC log blocks in ARC and without any other error, this means that the lbps array in the header is pointing to non-existent or invalid log blocks. Reset the device header in this case. In l2arc_rebuild() change the zfs_dbgmsg messages to spa_history_log_internal() making them user visible with zpool history command. Non-functional changes: Make the first test in persistent L2ARC use `zdb -lll` to increase coverage in `zdb.c`. Rename psize with asize when referring to log blocks, since L2ARC_SET_PSIZE stores the vdev aligned size for log blocks. Also rename dh_log_blk_entries to dh_log_entries to make it clear that it is a mirror of l2ad_log_entries. Added comments for both changes. Fix inaccurate comments for example in l2arc_log_blk_restore(). Add asserts at the end in l2arc_evict() and l2arc_write_buffers().

* Add support for boot environment data to be stored in the labelPaul Dagnelie2020-05-0713-22/+335
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modern bootloaders leverage data stored in the root filesystem to enable some of their powerful features. GRUB specifically has a grubenv file which can store large amounts of configuration data that can be read and written at boot time and during normal operation. This allows sysadmins to configure useful features like automated failover after failed boot attempts. Unfortunately, due to the Copy-on-Write nature of ZFS, the standard behavior of these tools cannot handle writing to ZFS files safely at boot time. We need an alternative way to store data that allows the bootloader to make changes to the data. This work is very similar to work that was done on Illumos to enable similar functionality in the FreeBSD bootloader. This patch is different in that the data being stored is a raw grubenv file; this file can store arbitrary variables and values, and the scripting provided by grub is powerful enough that special structures are not required to implement advanced behavior. We repurpose the second padding area in each label to store the grubenv file, protected by an embedded checksum. We add two ioctls to get and set this data, and libzfs_core and libzfs functions to access them more easily. There are no direct command line interfaces to these functions; these will be added directly to the bootloader utilities.

We emulate those operations for those platforms using a mutex. That is not entirely correct and it's very efficient. Besides, the loads are plain loads, so torn values are possible. Nevertheless, the emulation seems to work for some definition of work. This change adds atomic_swap_64, which is already used in ZFS code, and atomic_load_64 that can be used to prevent torn reads.

Ditto for atomic_cas_64 and atomic_fcmpset_64 on platforms that have it. The only exception is sparc64 that provides MD atomic_cas_32 and atomic_cas_64. This is slightly inefficient as fcmpset reports whether the operation updated the target and that information is not needed for cas. Nevertheless, there is less code to maintain and to add for new platforms. Also, the operations are done inline now as opposed to function calls before. atomic_add_64_nv is implemented using atomic_fetchadd_64 on platforms that provide it. casptr, cas32, atomic_or_8, atomic_or_8_nv are completely removed as they have no users. atomic_mtx that is used to emulate 64-bit atomics on platforms that lack them is defined only on those platforms. As a result, platform specific opensolaris_atomic.S files have lost most of their code. The only exception is i386 where the compat+contrib code provides 64-bit atomics for userland use. That code assumes availability of cmpxchg8b instruction. FreeBSD does not have that assumption for i386 userland and does not provide 64-bit atomics. Hopefully, this can and will be fixed.

Also, in the code that FreeBSD has ported from illumos membar_producer is used only with regular stores to regular memory (with respect to caching). We do not have an MI primitive for the store-store barrier, so atomic_thread_fence_rel is the closest we have as it provides (load | store) -> store barrier. Previously, membar_producer was an empty function call on all 32-bit arm-s, 32-bit powerpc, riscv and all mips variants. I think that it was inadequate. On other platforms, such as amd64, arm64, i386, powerpc64, sparc64, membar_producer was implemented using stronger primitives than required for a store-store barrier with respect to regular memory access. For example, it used sfence on amd64 and lock-ed nop in i386 (despite TSO). On powerpc64 we now use recommended lwsync instead of eieio. On sparc64 FreeBSD uses TSO mode. On arm64/aarch64 we now use dmb sy instead of dmb ish. Not sure if this is an improvement, actually. After this change we can drop opensolaris_atomic.S for aarch64, amd64, powerpc64 and sparc64 as all required atomic operations have either direct or light-weight mapping to FreeBSD native atomic operations.

| | | | | | | | | | | | | | Running zdb -l $disk shows a warning that zfs_arc_max is being ignored. zdb sets zfs_arc_max below zfs_arc_min, which causes the value to be ignored by arc_tuning_update(). Set zfs_arc_min to the bare minimum in zdb, which is below zfs_arc_max.

* Support custom URI schemes for the keylocation propertyJason King2020-04-283-194/+360
| | | | | | | | | | | | | | | | | | | | | Every platform has their own preferred methods for implementing URI schemes beyond the currently supported file scheme (e.g. 'https' on FreeBSD would likely use libfetch, while Linux distros and illumos would probably use libcurl, etc). It would be helpful if libzfs can be extended to support additional schemes in a simple manner. A table of (scheme, handler_function) pairs is added to libzfs_crypto.c, and the existing functions in libzfs_crypto.c so that when the key format is ZFS_KEYFORMAT_URI, the scheme from the URI string is extracted, and a matching handler it located in the aforementioned table (returning an error if no matching handler is found). The handler function is then invoked to retrieve the key material (in the format specified by the keyformat property) and the key is loaded or the handler can return an error to abort the key loading process.

* Fix missing ivset guid with resumed raw base recvTom Caputi2020-04-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | This patch corrects a bug introduced in 61152d1069. When resuming a raw base receive, the dmu_recv code always sets drc->drc_fromsnapobj to the object ID of the previous snapshot. For incrementals, this is correct, but for base sends, this should be left at 0. The presence of this ID eventually allows a check to run which determines whether or not the incoming stream and the previous snapshot have matching IVset guids. This check fails becuase it is not meant to run when there is no previous snapshot. When it does fail, the user receives an error stating that the incoming stream has the problem outlined in errata 4. This patch corrects this issue by simply ensuring drc->drc_fromsnapobj is left as 0 for base receives.

This should never happen in practice as documented by the assert, but initialize it regardless to resolve the warning.
