* Fix lseek(SEEK_DATA/SEEK_HOLE) mmap consistencyBrian Behlendorf2021-11-074-0/+155
| | | | | | | | | | | | | | | | | | | | | | | When using lseek(2) to report data/holes memory mapped regions of the file were ignored. This could result in incorrect results. To handle this zfs_holey_common() was updated to asynchronously writeback any dirty mmap(2) regions prior to reporting holes. Additionally, while not strictly required, the dn_struct_rwlock is now held over the dirty check to prevent the dnode structure from changing. This ensures that a clean dnode can't be dirtied before the data/hole is located. The range lock is now also taken to ensure the call cannot race with zfs_write(). Furthermore, the code was refactored to provide a dnode_is_dirty() helper function which checks the dnode for any dirty records to determine its dirtiness.

* Simplify and document OpenZFS library dependenciesBrian Behlendorf2021-10-073-8/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For those not already familiar with the code base it can be a challenge to understand how the libraries are laid out. This has sometimes resulted in functionality being added in the wrong place. To help avoid that in the future this commit documents the high-level dependencies for easy reference in lib/Makefile.am. It also simplifies a few things. - Switched libzpool dependency on libzfs_core to libzutil. This change makes it clear libzpool should never depend on the ioctl() functionality provided by libzfs_core. - Moved zfs_ioctl_fd() from libzutil to libzfs_core and renamed it lzc_ioctl_fd(). Normal access to the kmods should all be funneled through the libzfs_core library. The sole exception is the pool_active() which was updated to not use lzc_ioctl_fd() to remove the libzfs_core dependency. - Removed libzfs_core dependency on libzutil. - Removed the lib/libzfs/os/freebsd/libzfs_ioctl_compat.c source file which was all dead code. - Removed libzfs_core dependency from mkbusy and ctime test utilities. It was only needed for some trivial wrapper functions and that code is easy to replicate to shed the unneeded dependency.

This pool configuration allows all dRAID vdevs to participate when rebuilding to a distributed hot spare device. This can substantially reduce the total time required to restore full parity to pool with a failed device. A dRAID pool can be created using the new top-level `draid` type. Like `raidz`, the desired redundancy is specified after the type: `draid[1,2,3]`. No additional information is required to create the pool and reasonable default values will be chosen based on the number of child vdevs in the dRAID vdev. zpool create <pool> draid[1,2,3] <vdevs...> Unlike raidz, additional optional dRAID configuration values can be provided as part of the draid type as colon separated values. This allows administrators to fully specify a layout for either performance or capacity reasons. The supported options include: zpool create <pool> \ draid[<parity>][:<data>d][:<children>c][:<spares>s] \ <vdevs...> - draid[parity] - Parity level (default 1) - draid[:<data>d] - Data devices per group (default 8) - draid[:<children>c] - Expected number of child vdevs - draid[:<spares>s] - Distributed hot spares (default 0) Abbreviated example `zpool status` output for a 68 disk dRAID pool with two distributed spares using special allocation classes. ``` pool: tank state: ONLINE config: NAME STATE READ WRITE CKSUM slag7 ONLINE 0 0 0 draid2:8d:68c:2s-0 ONLINE 0 0 0 L0 ONLINE 0 0 0 L1 ONLINE 0 0 0 ...

These options are leverages by zloop.sh to test a wide range of dRAID configurations. -K draid|raidz|random - kind of RAID to test -D <value> - dRAID data drives per group -S <value> - dRAID distributed hot spares -R <value> - RAID parity (raidz or dRAID) The zpool_create, zpool_import, redundancy, replacement and fault test groups have all been updated provide test coverage for the dRAID feature.

* Unconditionally enable debugging for libzpoolSerapheim Dimitropoulos2020-07-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | We already enable -DDEBUG unconditionally (meaning regardless of this is a debug build or a performance build) for zdb and ztest as they are mostly used for development and debugging. This patch enables -DDEBUG for libzpool extending the debugging checks for zdb, ztest, and a couple of other test utilities. In addition to passing -DDEBUG we also enable -DZFS_DEBUG so all assertion checks work s expected. We do so not only in libzpool but in every utility that links to it, even if the utility doesn't directly use any functionality wrapped in ZFS_DEBUG macro definitions. The reason is that these utilities may still include headers that contain structs that have more fields when ZFS_DEBUG is defined. This can be a problem as enabling that flag for libzpool but not for zdb can lead into random problems (e.g. segmentation faults) as zdb may be have an incorrect view of a struct passed to it by libzpool.

* Use abs_top_builddir when referencing librariesArvind Sankar2020-07-103-6/+6
| | | | | | | | | | | | | | | | | | | | | libtool stores absolute paths in the dependency_libs component of the .la files. If the Makefile for a dependent library refers to the libraries by relative path, some libraries end up duplicated on the link command line. As an example, libzfs specifies libzfs_core, libnvpair and libuutil as dependencies to be linked in. The .la file for libzfs_core also specifies libnvpair, but using an absolute path, with the result that libnvpair is present twice in the linker command line for producing libzfs. While the only thing this causes is to slightly slow down the linking, we can avoid it by using absolute paths everywhere, including for convenience libraries just for consistency.

* Add config.rpath for AM_GNU_GETTEXTArvind Sankar2020-07-101-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | Commit e8864b1b28c2 ("config: libintl/libiconv for gettext() detection") added an empty config.rpath with a comment that the real one doesn't work with libtool. However, an empty config.rpath doesn't really work: eg. on FreeBSD, where libintl is in /usr/local/lib, configure thinks that gettext doesn't exist and NLS should be disabled, which currently isn't supported in the source, and hence requires manual workaround to directly link -lintl without relying on configure. config.rpath is essential to let it be detected either in --prefix or using --with-libintl-prefix. I also don't see the mentioned issue with libtool flags applied to compilation, it seems to work fine to pass LTLIBINTL to libtool. It's unnecessary to include LTLIBICONV as the configure test will automatically append that to LTLIBINTL if it is necessary to link with libiconv.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libzutil is currently statically linked into libzfs, libzfs_core and libzpool. Avoid the unnecessary duplication by removing it from libzfs and libzpool, and adding libzfs_core to libzpool. Remove a few unnecessary dependencies: - libuutil from libzfs_core - libtirpc from libspl - keep only libcrypto in libzfs, as we don't use any functions from libssl - librt is only used for clock_gettime, however on modern systems that's in libc rather than librt. Add a configure check to see if we actually need librt - libdl from raidz_test Add a few missing dependencies: - zlib to libefi and libzfs - libuuid to zpool, and libuuid and libudev to zed - libnvpair uses assertions, so add assert.c to provide aok and libspl_assertf Sort the LDADD for programs so that libraries that satisfy dependencies come at the end rather than the beginning of the linker command line. Revamp the configure tests for libaries to use FIND_SYSTEM_LIBRARY instead. This can take advantage of pkg-config, and it also avoids polluting LIBS. List all the required dependencies in the pkgconfig files, and move the one for libzfs_core into the latter's directory. Install pkgconfig files in $(libdir)/pkgconfig on linux and $(prefix)/libdata/pkgconfig on FreeBSD, instead of /usr/share/pkgconfig, as the more correct location for library .pc files.

* Add support for boot environment data to be stored in the labelPaul Dagnelie2020-05-071-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | Add a mechanism to wait for delete queue to drain. When doing redacted send/recv, many workflows involve deleting files that contain sensitive data. Because of the way zfs handles file deletions, snapshots taken quickly after a rm operation can sometimes still contain the file in question, especially if the file is very large. This can result in issues for redacted send/recv users who expect the deleted files to be redacted in the send streams, and not appear in their clones. This change duplicates much of the zpool wait related logic into a zfs wait command, which can be used to wait until the internal deleteq has been drained. Additional wait activities may be added in the future.

* Add subcommand to wait for background zfs activity to completeJohn Gallagher2019-09-131-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the best way to wait for the completion of a long-running operation in a pool, like a scrub or device removal, is to poll 'zpool status' and parse its output, which is neither efficient nor convenient. This change adds a 'wait' subcommand to the zpool command. When invoked, 'zpool wait' will block until a specified type of background activity completes. Currently, this subcommand can wait for any of the following: - Scrubs or resilvers to complete - Devices to initialized - Devices to be replaced - Devices to be removed - Checkpoints to be discarded - Background freeing to complete For example, a scrub that is in progress could be waited for by running zpool wait -t scrub <pool> This also adds a -w flag to the attach, checkpoint, initialize, replace, remove, and scrub subcommands. When used, this flag makes the operations kicked off by these subcommands synchronous instead of asynchronous. This functionality is implemented using a new ioctl. The type of activity to wait for is provided as input to the ioctl, and the ioctl blocks until all activity of that type has completed. An ioctl was used over other methods of kernel-userspace communiction primarily for the sake of portability. Porting Notes: This is ported from Delphix OS change DLPX-44432. The following changes were made while porting: - Added ZoL-style ioctl input declaration. - Reorganized error handling in zpool_initialize in libzfs to integrate better with changes made for TRIM support. - Fixed check for whether a checkpoint discard is in progress. Previously it also waited if the pool had a checkpoint, instead of just if a checkpoint was being discarded. - Exposed zfs_initialize_chunk_size as a ZoL-style tunable. - Updated more existing tests to make use of new 'zpool wait' functionality, tests that don't exist in Delphix OS. - Used existing ZoL tunable zfs_scan_suspend_progress, together with zinject, in place of a new tunable zfs_scan_max_blks_per_txg. - Added support for a non-integral interval argument to zpool wait. Future work: ZoL has support for trimming devices, which Delphix OS does not. In the future, 'zpool wait' could be extended to add the ability to wait for trim operations to complete.
