* Fix up arcstat(1) to match our versionAJ Jordan2020-05-112-19/+46
| | | | | | | | | | | | | Turns out the illumos manpage, which is what this originates from, was written for the original Perl version of the utility which is not the version in the OpenZFS tree. *That* version originates from a Python rewrite that was done for FreeNAS. So fix up the manpage to match what we actually ship (and fix a few typos in the process).

* Change zfsunlock for better busybox compatibilityRichard Laager2020-05-101-1/+1
| | | | | | | | | | | | | | It turns out that there are two versions of Busybox, at least on Ubuntu 18.04. If you have the busybox-static package installed, you get a busybox that supports `ps a` and `head`. If you only have busybox-initramfs, you don't. Either way, you have `awk`. This change should also make this compatible with GNU ps, if you somehow end up with that in the initramfs environment.

* 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. Authored by: avg <[email protected]> FreeBSD-commit: freebsd/freebsd@3458e5d1e6354123ec2b0953d29f98126aa442e cleanup of illumos compatibility atomics atomic_cas_32 is implemented using atomic_fcmpset_32 on all platforms. 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. Authored by: avg <[email protected]> FreeBSD-commit: freebsd/freebsd@e9642c209b4413f6afb41d3b2607c51d80a1a34 emulate illumos membar_producer with atomic_thread_fence_rel membar_producer is supposed to be a store-store barrier. 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.

For practical purposes, strong semantics means that if fcmpset fails then the reported current value is always different from the expected value. Weak semantics means that the reported current value may be the same as the expected value even though fcmpset failed. That's a so called "sporadic" failure. I originally implemented atomic_cas expecting strong semantics, but many platforms actually have weak one.

This is needed to unblock future improvements that reduce the need for locking on 64-bit platforms by using atomic updates. The implementation allows for future integration with userland atomic64, but as that implies going through sysarch for every use, the current status quo of userland doing its own locking may be for the best.

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.

* Remove deduplicated send/receive codeMatthew Ahrens2020-04-2326-1081/+219
| | | | | | | | | | | | | | | | | | | | | | | | | Deduplicated send streams (i.e. `zfs send -D` and `zfs receive` of such streams) are deprecated. Deduplicated send streams can be received by first converting them to non-deduplicated with the `zstream redup` command. This commit removes the code for sending and receiving deduplicated send streams. `zfs send -D` will now print a warning, ignore the `-D` flag, and generate a regular (non-deduplicated) send stream. `zfs receive` of a deduplicated send stream will print an error message and fail. The resulting code simplification (especially in the kernel's support for receiving dedup streams) should help enable future performance enhancements. Several new tests are added which leverage `zstream redup`.

* Use a struct to organize metaslab-group-allocator fieldsMatthew Ahrens2020-04-223-57/+62
| | | | | | | | | | | | | | | | | | | | Each metaslab group (of which there is one per top-level vdev) has several (4, by default) "metaslab group allocators". Each "allocator" has its own metaslab that it prefers to allocate from (the "primary" allocator), and each can perform allocations concurrently with the other allocators. In addition to the primary metaslab, there are several other fields that need to be tracked separately for each allocator. These are currently stored as several arrays in the metaslab_group_t, each array indexed by allocator number. This change organizes all the metaslab-group-allocator-specific fields into a new struct, metaslab_group_allocator_t. The metaslab_group_t now needs only one array indexed by the allocator number - which contains the metaslab_group_allocator_t's.

* Fix zfs send progress reportingMatthew Ahrens2020-04-203-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The progress of a send is supposed to be reported by `zfs send -v`, but it is not. This works by creating a new user thread (with pthread_create()) which does ZFS_IOC_SEND_PROGRESS ioctls to check how much progress has been made. This IOCTL finds the specified send (since there may be multiple concurrent sends in the system). The IOCTL also checks that the specified send was started by the current process. On Linux, different threads of the same process are represented as different `struct task_struct`s (and, confusingly, have different PID's). To check if if two threads are in the same process, we need to check if they have the same `struct task_struct:group_leader`. We used to to this correctly, but it was inadvertently changed by 30af21b02569 (Redacted Send) to simply check if the current `struct task_struct` is the one that started the send. This commit changes the code back to checking if the send was started by a `struct task_struct` with the same `group_leader` as the calling thread.
