+Description: Solaris Porting Layer user-space utilities for Linux (dummy)
+ The Solaris Porting Layer (SPL) is a Linux kernel module which provides
+ many of the Solaris kernel APIs. This shim layer makes it possible to
+ run Solaris kernel code in the Linux kernel with relatively minimal
+ modification. The Solaris Porting LAyer Tests (SPLAT) is a Linux kernel
+ module which provides a testing harness for the SPL module.
+ .
+ SPL can be particularly useful when you want to track upstream Illumos
+ (or any other OpenSolaris fork) development closely and don't want the
+ overhead of maintaining a large patch which converts Solaris primitives
+ to Linux primitives.
+ .
+ This is a transitional dummy package. It can safely be removed.

+Subject: [PATCH] Fix the path to the zed binary on the systemd unit.
+
+We install zed into /usr/sbin manually meanwhile the upstream default is
+installing it into /sbin. Ubuntu packages also install zed to /usr/sbin, but
+they ship their own zfs-zed unit.

+Subject: [PATCH] dont symlink zed scripts
+
+Of the zedlet scripts shipped by upstream, a subset are enabled by
+default, by creating symlinks in /etc/zfs/zed.d.  These symlinks are
+shipped in the zfs-zed package.  dpkg, however, does not support
+conffile handling of symlinks, and therefore any changes (removals) to
+the symlinks are not preserved on package upgrade.
+
+To address this policy violation, we:
+
+ 1. During package build, create a list of enabled-by-default zedlets,
+    instead of creating symlinks.
+ 2. On package removal, identify all enabled-by-default zedlets whose
+    symlinks do not exist (i.e., were removed by the user). This is done
+    by creating "whiteout" links to /dev/null in their place).
+ 3. On package installation, create links to enabled-by-default zedlets
+    UNLESS there is already a file there (i.e., abort if there is a
+    whiteout link).
+ 4. We also clean up broken symlinks to removed zedlets at package
+    postinst.
+
+Description: track default symlinks, instead of symlinking

+Subject: [PATCH] Add systemd-unit for importing specific pools
+
+The unit can be instantiated with a specific poolname, which will get imported
+by scanning /dev/disk/by-id, irrespective of the existence and content of
+/etc/zfs/zpool.cache.
+
+the instance name is used unescaped (see systemd.unit(5)), since zpool names
+can contain characters which will be escaped by systemd.
+
+Its instances are ordered before the other two "big" import services to avoid
+races and spurious (cosmetic!) service failures.

+
+commit 085321621e79a75bea41c2b6511da6ebfbf2ba0a added printing MFU
+and MRU stats for 2.1 user space tools, but those keys are not
+available in the 2.0 module. That means it may break the arcstat and
+arc_summary tools after upgrade to 2.1 (user space), before a reboot
+to the new 2.1 ZFS kernel-module happened, due to python raising a
+KeyError on the dict access then.
+
+Move those two keys to a .get accessor with `0` as fallback, as it
+should be better to show some possible wrong data for new stat-keys
+than throwing an exception.
+
+Signed-off-by: Thomas Lamprecht <t.lamprecht@proxmox.com>
+
+also move l2_mfu_asize  l2_mru_asize l2_prefetch_asize
+l2_bufc_data_asize l2_bufc_metadata_asize to .get accessor
+(these are only present with a cache device in the pool)

+Subject: [PATCH] Fix nfs_truncate_shares without /etc/exports.d
+
+Calling nfs_reset_shares on Linux prints a warning:
+`failed to lock /etc/exports.d/zfs.exports.lock: No such file or
+directory`
+when /etc/exports.d does not exist. The directory gets created, when a
+filesystem is actually exported through nfs_toggle_share and
+nfs_init_share. The truncation of /etc/exports.d/zfs.exports happens
+unconditionally when calling `zfs mount -a` (via zfs_do_mount and
+share_mount in `cmd/zfs/zfs_main.c`).
+
+Fixing the issue only in the Linux part, since the exports file on
+freebsd is in `/etc/zfs/`, which seems present on 2 FreeBSD systems I
+have access to (through `/etc/zfs/compatibility.d/`), while a Debian
+box does not have the directory even if `/usr/sbin/exportfs` is
+present through the `nfs-kernel-server` package.
+
+The code for exports_available is copied from nfs_available above.
+
+Fixes: ede037cda73675f42b1452187e8dd3438fafc220
+("Make zfs-share service resilient to stale exports")

+Subject: [PATCH] zpool status: tighten bounds for noalloc stat availabillity
+
+When running zfs 2.2.0 userspace utilities with a kernel that still
+has 2.1.13 modules zpool status adds `(non-allocating)` next to the
+disk name of a single-disk pool.
+
+The reason for this seems to be that the patch adding the `vs_pspace` field was
+backported, but the one adding `vs_noalloc` was not.
+
+Itself that is not a problem, but in 2.2 `noalloc` was added before `psspace`,
+so the struct layout between 2.1.13 and 2.2.0 do NOT match anymore...
+
+I.e., the struct looks like the following at the end for ZFS 2.1.x:
+
+```
+typedef struct vdev_stat {
+    hrtime_t        vs_timestamp;           /* time since vdev load */
+    // snip
+    uint64_t        vs_logical_ashift;      /* vdev_logical_ashift  */
+    uint64_t        vs_physical_ashift;     /* vdev_physical_ashift */
+    uint64_t        vs_pspace;              /* physical capacity */
+} vdev_stat_t;
+```
+
+And like the following on ZFS 2.2.x:
+```
+typedef struct vdev_stat {
+    hrtime_t        vs_timestamp;           /* time since vdev load */
+    // snip
+    uint64_t        vs_logical_ashift;      /* vdev_logical_ashift  */
+    uint64_t        vs_physical_ashift;     /* vdev_physical_ashift */
+    uint64_t        vs_noalloc;             /* allocations halted?  */
+    uint64_t        vs_pspace;              /* physical capacity */
+} vdev_stat_t;
+```
+
+Resulting in 2.2.x user-space tooling interpreting the `vs_pspace` field from
+the 2.1.x kernel module as `vs_noalloc` field.
+
+For now, work-around that discrepancy by coupling the availability of
+the vs_noalloc field with the one of the vs_pspace one, as when both
+are returned from the module we can be sure that our struct layout
+matches again.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+If a zvol has more than 15 partitions, the minor device number exhausts
+the slot count reserved for partitions next to the zvol itself. As a
+result, the minor number cannot be used to determine the partition
+number for the higher partition, and doing so results in wrong named
+symlinks being generated by udev.
+
+Since the partition number is encoded in the block device name anyway,
+let's just extract it from there instead.

+The regular ABD iterators yield data buffers, so they have to map and

+unnecessary overhead.
+
+This adds adb_iterate_page_func, which yields unmapped struct page

+Subject: [PATCH] vdev_disk: rewrite BIO filling machinery to avoid split pages
+
+This commit tackles a number of issues in the way BIOs (`struct bio`)
+are constructed for submission to the Linux block layer.
+
+The kernel has a hard upper limit on the number of pages/segments that
+can be added to a BIO, as well as a separate limit for each device
+(related to its queue depth and other scheduling characteristics).
+
+ZFS counts the number of memory pages in the request ABD
+(`abd_nr_pages_off()`, and then uses that as the number of segments to
+put into the BIO, up to the hard upper limit. If it requires more than
+the limit, it will create multiple BIOs.
+
+Leaving aside the fact that page count method is wrong (see below), not
+limiting to the device segment max means that the device driver will
+need to split the BIO in half. This is alone is not necessarily a
+problem, but it interacts with another issue to cause a much larger
+problem.
+
+The kernel function to add a segment to a BIO (`bio_add_page()`) takes a
+`struct page` pointer, and offset+len within it. `struct page` can
+represent a run of contiguous memory pages (known as a "compound page").
+In can be of arbitrary length.
+
+The ZFS functions that count ABD pages and load them into the BIO
+(`abd_nr_pages_off()`, `bio_map()` and `abd_bio_map_off()`) will never
+consider a page to be more than `PAGE_SIZE` (4K), even if the `struct
+page` is for multiple pages. In this case, it will load the same `struct
+page` into the BIO multiple times, with the offset adjusted each time.
+
+With a sufficiently large ABD, this can easily lead to the BIO being
+entirely filled much earlier than it could have been. This is also
+further contributes to the problem caused by the incorrect segment limit
+calculation, as its much easier to go past the device limit, and so
+require a split.
+
+Again, this is not a problem on its own.
+
+The logic for "never submit more than `PAGE_SIZE`" is actually a little
+more subtle. It will actually never submit a buffer that crosses a 4K
+page boundary.
+
+In practice, this is fine, as most ABDs are scattered, that is a list of
+complete 4K pages, and so are loaded in as such.
+
+Linear ABDs are typically allocated from slabs, and for small sizes they
+are frequently not aligned to page boundaries. For example, a 12K
+allocation can span four pages, eg:
+
+     -- 4K -- -- 4K -- -- 4K -- -- 4K --
+    |        |        |        |        |
+          :## ######## ######## ######:    [1K, 4K, 4K, 3K]
+
+Such an allocation would be loaded into a BIO as you see:
+
+    [1K, 4K, 4K, 3K]
+
+This tends not to be a problem in practice, because even if the BIO were
+filled and needed to be split, each half would still have either a start
+or end aligned to the logical block size of the device (assuming 4K at
+least).
+
+---
+
+In ideal circumstances, these shortcomings don't cause any particular
+problems. Its when they start to interact with other ZFS features that
+things get interesting.
+
+Aggregation will create a "gang" ABD, which is simply a list of other
+ABDs. Iterating over a gang ABD is just iterating over each ABD within
+it in turn.
+
+Because the segments are simply loaded in order, we can end up with
+uneven segments either side of the "gap" between the two ABDs. For
+example, two 12K ABDs might be aggregated and then loaded as:
+
+    [1K, 4K, 4K, 3K, 2K, 4K, 4K, 2K]
+
+Should a split occur, each individual BIO can end up either having an
+start or end offset that is not aligned to the logical block size, which
+some drivers (eg SCSI) will reject. However, this tends not to happen
+because the default aggregation limit usually keeps the BIO small enough
+to not require more than one split, and most pages are actually full 4K
+pages, so hitting an uneven gap is very rare anyway.
+
+If the pool is under particular memory pressure, then an IO can be
+broken down into a "gang block", a 512-byte block composed of a header
+and up to three block pointers. Each points to a fragment of the
+original write, or in turn, another gang block, breaking the original
+data up over and over until space can be found in the pool for each of
+them.
+
+Each gang header is a separate 512-byte memory allocation from a slab,
+that needs to be written down to disk. When the gang header is added to
+the BIO, its a single 512-byte segment.
+
+Pulling all this together, consider a large aggregated write of gang
+blocks. This results a BIO containing lots of 512-byte segments. Given
+our tendency to overfill the BIO, a split is likely, and most possible
+split points will yield a pair of BIOs that are misaligned. Drivers that
+care, like the SCSI driver, will reject them.
+
+---
+
+This commit is a substantial refactor and rewrite of much of `vdev_disk`
+to sort all this out.
+
+`vdev_bio_max_segs()` now returns the ideal maximum size for the device,
+if available. There's also a tuneable `zfs_vdev_disk_max_segs` to
+override this, to assist with testing.
+
+We scan the ABD up front to count the number of pages within it, and to
+confirm that if we submitted all those pages to one or more BIOs, it
+could be split at any point with creating a misaligned BIO.  If the
+pages in the BIO are not usable (as in any of the above situations), the
+ABD is linearised, and then checked again. This is the same technique
+used in `vdev_geom` on FreeBSD, adjusted for Linux's variable page size
+and allocator quirks.
+
+`vbio_t` is a cleanup and enhancement of the old `dio_request_t`. The
+idea is simply that it can hold all the state needed to create, submit
+and return multiple BIOs, including all the refcounts, the ABD copy if
+it was needed, and so on. Apart from what I hope is a clearer interface,
+the major difference is that because we know how many BIOs we'll need up
+front, we don't need the old overflow logic that would grow the BIO
+array, throw away all the old work and restart. We can get it right from
+the start.

+
+This makes the submission method selectable at module load time via the

+to 2.2 safely, and disabled in favour of the "classic" submission method
+if new problems come up.

+Subject: [PATCH] abd_iter_page: don't use compound heads on Linux <4.5
+
+Before 4.5 (specifically, torvalds/linux@ddc58f2), head and tail pages
+in a compound page were refcounted separately. This means that using the
+head page without taking a reference to it could see it cleaned up later
+before we're finished with it. Specifically, bio_add_page() would take a
+reference, and drop its reference after the bio completion callback
+returns.
+
+If the zio is executed immediately from the completion callback, this is
+usually ok, as any data is referenced through the tail page referenced
+by the ABD, and so becomes "live" that way. If there's a delay in zio
+execution (high load, error injection), then the head page can be freed,
+along with any dirty flags or other indicators that the underlying
+memory is used. Later, when the zio completes and that memory is
+accessed, its either unmapped and an unhandled fault takes down the
+entire system, or it is mapped and we end up messing around in someone
+else's memory. Both of these are very bad.
+
+The solution on these older kernels is to take a reference to the head
+page when we use it, and release it when we're done. There's not really
+a sensible way under our current structure to do this; the "best" would
+be to keep a list of head page references in the ABD, and release them
+when the ABD is freed.
+
+Since this additional overhead is totally unnecessary on 4.5+, where
+head and tail pages share refcounts, I've opted to simply not use the
+compound head in ABD page iteration there. This is theoretically less
+efficient (though cleaning up head page references would add overhead),
+but its safe, and we still get the other benefits of not mapping pages
+before adding them to a bio and not mis-splitting pages.
+
+There doesn't appear to be an obvious symbol name or config option we
+can match on to discover this behaviour in configure (and the mm/page
+APIs have changed a lot since then anyway), so I've gone with a simple
+version check.

+Subject: [PATCH] Fix corruption caused by mmap flushing problems
+
+1) Make mmap flushes synchronous. Linux may skip flushing dirty pages
+   already in writeback unless data-integrity sync is requested.
+
+2) Change zfs_putpage to use TXG_WAIT. Otherwise dirty pages may be
+   skipped due to DMU pushing back on TX assign.
+
+3) Add missing mmap flush when doing block cloning.
+
+4) While here, pass errors from putpage to writepage/writepages.
+
+This change fixes corruption edge cases, but unfortunately adds
+synchronous ZIL flushes for dirty mmap pages to llseek and bclone
+operations. It may be possible to avoid these sync writes later
+but would need more tricky refactoring of the writeback code.

+Subject: [PATCH] vdev_disk: don't touch vbio after its handed off to the
+ kernel
+
+After IO is unplugged, it may complete immediately and vbio_completion
+be called on interrupt context. That may interrupt or deschedule our
+task. If its the last bio, the vbio will be freed. Then, we get
+rescheduled, and try to write to freed memory through vbio->.
+
+This patch just removes the the cleanup, and the corresponding assert.
+These were leftovers from a previous iteration of vbio_submit() and were
+always "belt and suspenders" ops anyway, never strictly required.

--Description: Solaris Porting Layer kernel modules for Linux
-- The Solaris Porting Layer (SPL) is a Linux kernel module which provides
-- many of the Solaris kernel APIs. This shim layer makes it possible to
-- run Solaris kernel code in the Linux kernel with relatively minimal
-- modification. The Solaris Porting LAyer Tests (SPLAT) is a Linux kernel
-- module which provides a testing harness for the SPL module.
-- .
-- SPL can be particularly useful when you want to track upstream Illumos
-- (or any other OpenSolaris fork) development closely and don't want the
-- overhead of maintaining a large patch which converts Solaris primitives
-- to Linux primitives.
-- .
-- This package contains the source code for the SPL and SPLAT Linux kernel
-- modules, which can be used with DKMS, so that local kernel modules are
-- automatically built and installed every time the kernel packages are
-- upgraded.
