* Add libzutil for libzfs or libzpool consumersDon Brady2018-11-052-10/+4
| | | | | | | | | | | Adds a libzutil for utility functions that are common to libzfs and libzpool consumers (most of what was in libzfs_import.c). This removes the need for utilities to link against both libzpool and libzfs.

* Project Quota on ZFSNasf-Fan2018-02-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Project quota is a new ZFS system space/object usage accounting and enforcement mechanism. Similar as user/group quota, project quota is another dimension of system quota. It bases on the new object attribute - project ID. Project ID is a numerical value to indicate to which project an object belongs. An object only can belong to one project though you (the object owner or privileged user) can change the object project ID via 'chattr -p' or 'zfs project [-s] -p' explicitly. The object also can inherit the project ID from its parent when created if the parent has the project inherit flag (that can be set via 'chattr +P' or 'zfs project -s [-p]'). By accounting the spaces/objects belong to the same project, we can know how many spaces/objects used by the project. And if we set the upper limit then we can control the spaces/objects that are consumed by such project. It is useful when multiple groups and users cooperate for the same project, or a user/group needs to participate in multiple projects. Support the following commands and functionalities: zfs set projectquota@project zfs set projectobjquota@project zfs get projectquota@project zfs get projectobjquota@project zfs get projectused@project zfs get projectobjused@project zfs projectspace zfs allow projectquota zfs allow projectobjquota zfs allow projectused zfs allow projectobjused zfs unallow projectquota zfs unallow projectobjquota zfs unallow projectused zfs unallow projectobjused chattr +/-P chattr -p project_id lsattr -p This patch also supports tree quota based on the project quota via "zfs project" commands set as following: zfs project [-d|-r] <file|directory ...> zfs project -C [-k] [-r] <file|directory ...> zfs project -c [-0] [-d|-r] [-p id] <file|directory ...> zfs project [-p id] [-r] [-s] <file|directory ...> For "df [-i] $DIR" command, if we set INHERIT (project ID) flag on the $DIR, then the proejct [obj]quota and [obj]used values for the $DIR's project ID will be shown as the total/free (avail) resource. Keep the same behavior as EXT4/XFS does.

* Add libtpool (thread pools)Brian Behlendorf2017-08-091-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OpenZFS provides a library called tpool which implements thread pools for user space applications. Porting this library means the zpool utility no longer needs to borrow the kernel mutex and taskq interfaces from libzpool. This code was updated to use the tpool library which behaves in a very similar fashion. Porting libtpool was relatively straight forward and minimal modifications were needed. The core changes were: * Fully convert the library to use pthreads. * Updated signal handling. * lmalloc/lfree converted to calloc/free * Implemented portable pthread_attr_clone() function. Finally, update the build system such that libzpool.so is no longer linked in to zfs(8), zpool(8), etc. All that is required is libzfs to which the zcommon soures were added (which is the way it always should have been). Removing the libzpool dependency resulted in several build issues which needed to be resolved. * Moved zfeature support to module/zcommon/zfeature_common.c * Moved ratelimiting to to module/zfs/zfs_ratelimit.c * Moved get_system_hostid() to lib/libspl/gethostid.c * Removed use of cmn_err() in zcommon source * Removed dprintf_setup() call from zpool_main.c and zfs_main.c * Removed highbit() and lowbit() * Removed unnecessary library dependencies from Makefiles * Removed fletcher-4 kstat in user space * Added sha2 support explicitly to libzfs * Added highbit64() and lowbit64() to zpool_util.c Reviewed-by: Tony Hutter <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #6442

* Multi-modifier protection (MMP)Olaf Faaland2017-07-131-44/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add multihost=on|off pool property to control MMP. When enabled a new thread writes uberblocks to the last slot in each label, at a set frequency, to indicate to other hosts the pool is actively imported. These uberblocks are the last synced uberblock with an updated timestamp. Property defaults to off. During tryimport, find the "best" uberblock (newest txg and timestamp) repeatedly, checking for change in the found uberblock. Include the results of the activity test in the config returned by tryimport. These results are reported to user in "zpool import". Allow the user to control the period between MMP writes, and the duration of the activity test on import, via a new module parameter zfs_multihost_interval. The period is specified in milliseconds. The activity test duration is calculated from this value, and from the mmp_delay in the "best" uberblock found initially. Add a kstat interface to export statistics about Multiple Modifier Protection (MMP) updates. Include the last synced txg number, the timestamp, the delay since the last MMP update, the VDEV GUID, the VDEV label that received the last MMP update, and the VDEV path. Abbreviated output below. $ cat /proc/spl/kstat/zfs/mypool/multihost 31 0 0x01 10 880 105092382393521 105144180101111 txg timestamp mmp_delay vdev_guid vdev_label vdev_path 20468 261337 250274925 68396651780 3 /dev/sda 20468 261339 252023374 6267402363293 1 /dev/sdc 20468 261340 252000858 6698080955233 1 /dev/sdx 20468 261341 251980635 783892869810 2 /dev/sdy 20468 261342 253385953 8923255792467 3 /dev/sdd 20468 261344 253336622 042125143176 0 /dev/sdab 20468 261345 253310522 1200778101278 2 /dev/sde 20468 261346 253286429 0950576198362 2 /dev/sdt 20468 261347 253261545 96209817917 3 /dev/sds 20468 261349 253238188 8555725937673 3 /dev/sdb Add a new tunable zfs_multihost_history to specify the number of MMP updates to store history for. By default it is set to zero meaning that no MMP statistics are stored. When using ztest to generate activity, for automated tests of the MMP function, some test functions interfere with the test. For example, the pool is exported to run zdb and then imported again. Add a new ztest function, "-M", to alter ztest behavior to prevent this. Add new tests to verify the new functionality.

* Cleanup linkingRichard Yao2016-03-181-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed during code review of zfsonlinux/zfs#4385 that the author of a commit had peppered the various Makefile.am files with `$(TIRPC_LIBS)` when putting it into `lib/libspl/Makefile.am` should have sufficed. Upon further examination, it seems that he had copied what we do with `$(ZLIB)`. We also have a bit of that with `-ldl` too. Unfortunately, what we do is wrong, so lets fix it to set a good example for future contributors. In addition, we have multiple `-lz` and `-luuid` passed to the compiler because each `AC_CHECK_LIB` adds it to `$LIBS`. That is somewhat annoying to see, so we switch to `AC_SEARCH_LIBS` to avoid it. This is consistent with the recommendation to use `AC_SEARCH_LIBS` over `AC_CHECK_LIB` by autotools upstream: https://www.gnu.org/software/autoconf/manual/autoconf-2.66/html_node/Libraries.html In an ideal world, this would translate into improvements in ELF's `DT_NEEDED` entries, but that is not the case because of a couple of bugs in libtool. The first bug causes libtool to overlink by using static link dependencies for dynamic linking: https://wiki.mageia.org/en/Overlinking_issues_in_packaging#libtool_issues The workaround for this should be to pass `-Wl,--as-needed` in `LDFLAGS`. That leads us to the second bug, where libtool passes `LDFLAGS` after the libraries are specified and `ld` will only honor `--as-needed` on libraries specified before it: https://sigquit.wordpress.com/2011/02/16/why-asneeded-doesnt-work-as-expected-for-your-libraries-on-your-autotools-project/ There are a few possible workarounds for the second bug. One is to either patch the compiler spec file to specify `-Wl,--as-needed` or pass `-Wl,--as-needed` via `CC` like `CC='gcc -Wl,--as-needed'` so that it is specified early. Another is to patch ltmain.sh like Gentoo does: https://gitweb.gentoo.org/repo/gentoo.git/tree/eclass/ELT-patches/as-needed Without one of those workarounds, this cleanup provides no benefit in terms of `DT_NEEDED` entry generation. It should still be an improvement because it nicely simplifies the code while encouraging good habits when patching autotools scripts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Build products from an out of tree build should be written relative to the build directory. Sources should be referred to by their locations in the source directory. This is accomplished by adding the 'src' and 'obj' variables for the module Makefile.am, using relative paths to reference source files, and by setting VPATH when source files are not co-located with the Makefile. This enables the following: $ mkdir build $ cd build $ ../configure \ --with-spl=$HOME/src/git/spl/ \ --with-spl-obj=$HOME/src/git/spl/build $ make -s This change also has the advantage of resolving the following warning which is generated by modern versions of automake.

* Generate libraries with correct DT_NEEDED entriesRichard Yao2013-10-101-1/+1
| | | | | | | | | | | | | | | | | | | | Libraries that depend on other libraries should list them in ELF's DT_NEEDED field so that programs linking to them do not need to specify those libraries unless they depend on them as well. This is not the case in the current code and the consequence is that anything that needs a library must know its dependencies. This is fragile and caused GRUB2's configure script to break when a dependency was added on libblkid in libzfs. This resolves that problem by using LIBADD/LDADD to specify libraries in Makefile.am instead of LDFLAGS. This ensures that proper DT_NEEDED entries are generated and prevents GRUB2's configure script from breaking in the presence of a libblkid dependency. This also removes unneeded dependencies from various files. Signed-off-by: Richard Yao <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Issue #1751
