The aggregation created by llquantize() partitions values into buckets; the
lower bound of the bucket containing the largest values is b^{m+1}, where
b and m are the second and fourth parameters to the action, respectively.
Bucket bounds are stored in a 64-bit integer, and so the llquantize()
validation checks need to verify that b^{m+1} fits in 64 bits. However, it
was only verifying that b^{m-1} fits in 64 bits, so certain parameter
combinations could trigger assertion failures in libdtrace.

At present, the kernel side code seems to blindly rollback to whatever happens
to be the latest snapshot at the time when the rollback task is processed.
The expected target's name should be passed to the kernel driver and the sync
task should validate that the target exists and that it is the latest snapshot
indeed.

The problem is that zfs_get_data() supplies a stale zgd_bp to dmu_sync(), which
we then nopwrite against.
zfs_get_data() doesn't hold any DMU-related locks, so after it copies db_blkptr
to zgd_bp, dbuf_write_ready()
could change db_blkptr, and dbuf_write_done() could remove the dirty record.
dmu_sync() then sees the stale
BP and that the dbuf it not dirty, so it is eligible for nop-writing.
The fix is for dmu_sync() to copy db_blkptr to zgd_bp after acquiring the
db_mtx. We could still see a stale
db_blkptr, but if it is stale then the dirty record will still exist and thus
we won't attempt to nopwrite.

- Store the symbol table contents in an anonymous swap-backed object. Have
mmap(/dev/ksyms) map that object, and stop mapping the symbol table into
the calling process in ksyms_open(). Previously we would cache a pointer
to the pmap of the opening process, and mmap(/dev/ksyms) would create a
mapping using the physical address found by a pmap lookup at the initial
mapping address. However, this assumes that the cached pmap is valid,
which may not be the case. [1]
- Remove the ksyms ioctl interface. It appears to have been added to work
around a limitation in libelf that no longer exists; see r321842.
Moreover, the interface is difficult to support and isn't present in
illumos. Since ksyms was added specifically to support lockstat(1), it
is expected that this removal won't have any real impact.
- Simplify ksyms_read() to avoid unnecessary copying.
- Don't call the device handle destructor if we fail to capture a snapshot
of the kernel's symbol table. devfs will do that for us.

The ARC buf data project (known simply as "ABD" since its genesis in the ZoL
community) changes the way the ARC allocates `b_pdata` memory from using linear
`void *` buffers to using scatter/gather lists of fixed-size 1KB chunks. This
improves ZFS's performance by helping to defragment the address space occupied
by the ARC, in particular for cases where compressed ARC is enabled. It could
also ease future work to allocate pages directly from `segkpm` for minimal-
overhead memory allocations, bypassing the `kmem` subsystem.
This is essentially the same change as the one which recently landed in ZFS on
Linux, although they made some platform-specific changes while adapting this
work to their codebase:
1. Implemented the equivalent of the `segkpm` suggestion for future work
mentioned above to bypass issues that they've had with the Linux kernel memory
allocator.
2. Changed the internal representation of the ABD's scatter/gather list so it
could be used to pass I/O directly into Linux block device drivers. (This
feature is not available in the illumos block device interface yet.)
FreeBSD notes:
- the actual (default) chunk size is 4KB (despite the text above saying 1KB)
- we can try to reimplement ABDs, so that they are not permanently
mapped into the KVA unless explicitly requested, especially on
platforms with scarce KVA
- we can try to use unmapped I/O and avoid intermediate allocation of a
linear, virtual memory mapped buffer
- we can try to avoid extra data copying by referring to chunks / pages
in the original ABD

When calling zpool import, zpool does a few ioctls to ZFS.
zpool allocates a buffer in userland and passes it to the kernel so that ZFS
can copy info into it. ZFS will use it to put the nvlist that describes the
pool configuration.
If the allocated buffer is too small, ZFS will return ENOMEM and the call will
have to be redone. This wastes CPU time and slows down the import process. This
happens very often for the ZFS_IOC_POOL_TRYIMPORT call.

When evicting from the ARC, we manipulate some refcount_t's, e.g. arcs_size.
When using zdb to examine a large amount of data (e.g. zdb -bb on a large pool
with small blocks), the ARC may have a large number of entries. If reference
tracking is enabled, there will be ~1 reference for each block in the ARC. When
evicting, we decrement the refcount and have to search all the references to
find the one that we are removing, which is very slow.
Since zdb is typically used to find problems with the on-disk format, and not
with the code it is running, we should disable reference tracking in zdb.

ABI breakage is mitigated by providing compatibility using versioned

by employing other tricks. Unfortunately, not everything can be
fixed, especially outside the base system. For instance, third-party
APIs which pass struct stat around are broken in backward and
forward incompatible ways.
Kinfo sysctl MIBs ABI is changed in backward-compatible way, but
there is no general mechanism to handle other sysctl MIBS which
return structures where the layout has changed. It was considered
that the breakage is either in the management interfaces, where we
usually allow ABI slip, or is not important.
Struct xvnode changed layout, no compat shims are provided.
For struct xtty, dev_t tty device member was reduced to uint32_t.
It was decided that keeping ABI compat in this case is more useful

This change introduces a new weighting algorithm to improve metaslab selection.
The new weighting algorithm relies on the SPACEMAP_HISTOGRAM feature. As a result,
the metaslab weight now encodes the type of weighting algorithm used
(size-based vs segment-based).
This also introduce a new allocation tracing facility and two new dcmds to help
debug allocation problems. Each zio now contains a zio_alloc_list_t structure
that is populated as the zio goes through the allocations stage. Here's an
example of how to use the tracing facility:

1 1 200 1 x 4M 112b000 mirror-1
- 2 200 0 NOT_ALLOCATABLE mirror-2
If the metaslab is using segment-based weighting then the WEIGHT column will
display the number of segments available in the bucket where the allocation
attempt was made.

Aliases are normally given names that include a key that's unique for each
input object file. This, for example, ensures that aliases for identically
named local symbols in different object files don't conflict. However, in
some cases the static linker will leave an undefined alias after merging
identical weak symbols, resulting in a link error. A non-unique name allows
the aliases to be merged as well.

libdtrace needs to append to the input object files' string and symbol
tables. Currently it does so by allocating a larger buffer, copying the
existing sections into them, and swapping pointers in the libelf data
descriptors. However, it also frees those buffers when its processing is
complete, which leads to a double free since the elftoolchain libelf
owns them and also frees them in elf_end(3). Instead, free the buffers
originally allocated by libelf.

When recording probe site addresses in the output DOF file, dtrace -G
needs to emit relocations for the .SUNW_dof section in order to obtain
the addresses of functions containing probe sites. DTrace expects the
addresses to be relative to the base address of the final ELF file,
and the amd64 USDT implementation was relying on some unspecified and
incorrect behaviour in the base system GNU ld to achieve this.
This change reimplements the probe site relocation handling to allow
USDT to be used with lld and newer GNU binutils. Specifically, it
makes use of R_X86_64_PC64/R_386_PC32 relocations to obtain the
probe site address relative to the DOF file address, and adds and uses a
new DOF relocation type which computes the final probe site address using
these relative offsets.

dtrace converts pairs of consecutive underscores in a probe name to dashes.
When dtrace -G processes relocations corresponding to USDT probe sites, it
performs this conversion on the corresponding symbol names prior to looking
up the resulting probe names in the USDT provider definition. However, in
so doing it would actually modify the input object's string table, which
breaks the string suffix merging done by recent binutils. Because we don't
care about the symbol name once the probe site is recorded, just perform the
probe lookup using a temporary copy.

Enumeration of return probes involves disassembling subroutines in the
target process, and ptrace(2) is currently used to read from the target
process. libproc could read from the backing file instead to avoid this
problem, but in the common case libdtrace will have a writeable handle
on the process anyway. In particular, a writeable handle is needed to list
USDT probes, and libdtrace will cache such a handle for processes that it
controls via dtrace -c and -p.
This change adds some handling for the equivalent of Solaris' PGRAB_*
flags. In particular, support for PGRAB_RDONLY is needed to avoid a
nasty deadlock: dtrace(1) may otherwise stop the master process for its
pseudo-terminal and end up blocking while writing to standard output.
When looking up an object by name, allow prefix matches if no direct match
is found. This allows one to, for example, match libc entry probes with:
# dtrace -n 'pid$target:libc.so::entry' -c ./foo
instead of requiring "libc.so.7" or a glob.
Also remove proc_obj2map() as it currently just duplicates the
functionality of proc_name2map(). It's supposed to take a Solaris
link-map ID as a paramter, but support for this isn't implemented and
isn't required to support DTrace's pid provider.
Fix a segfault in ctfmerge(1) due to a bug in GCC.
The change was correct and the bug real, but upstream didn't adopt it
and we want to remain in sync. When/if upstream does something about it
we can bring their version.
The bug in question was fixed in GCC 4.9 which is now the default in
FreeBSD's ports. Our native gcc-4.2, which is still in use in some Tier-2
platforms also has a workaround so no end-user should be harmed by the
revert.
due to zl_itx_list_sz not updated when async itx'es upgraded to sync.
Actually because of other changes about that time zl_itx_list_sz is not
really required to implement the functionality, so this patch removes
some unneeded broken code and variables.
Original idea of zil_slog_limit was to reduce chance of SLOG abuse by
single heavy logger, that increased latency for other (more latency critical)
loggers, by pushing heavy log out into the main pool instead of SLOG. Beside
huge latency increase for heavy writers, this implementation caused double
write of all data, since the log records were explicitly prepared for SLOG.
Since we now have I/O scheduler, I've found it can be much more efficient
to reduce priority of heavy logger SLOG writes from ZIO_PRIORITY_SYNC_WRITE
to ZIO_PRIORITY_ASYNC_WRITE, while still leave them on SLOG.
Existing ZIL implementation had problem with space efficiency when it
has to write large chunks of data into log blocks of limited size. In some
cases efficiency stopped to almost as low as 50%. In case of ZIL stored on
spinning rust, that also reduced log write speed in half, since head had to
uselessly fly over allocated but not written areas. This change improves
the situation by offloading problematic operations from z*_log_write() to
zil_lwb_commit(), which knows real situation of log blocks allocation and
can split large requests into pieces much more efficiently. Also as side
effect it removes one of two data copy operations done by ZIL code WR_COPIED
case.
While there, untangle and unify code of z*_log_write() functions.
Also zfs_log_write() alike to zvol_log_write() can now handle writes crossing
block boundary, that may also improve efficiency if ZPL is made to do that.

Currently lzc_receive() requires that its snapname argument is a snapshot name
(contains '@').
zfs receive allows to specify just a dataset name and would try to deduce the
snapshot name from the stream.
I propose to allow lzc_receive() to do the same.
That seems to be quite easy to implement, it requires only a small amount of
logic, it does not require any additional system calls or any additional data
from the stream.
The benefit is that the new behavior would allow to keep the snapshot names the
same between the sender and receiver at zero cost, without a need to pass the
names out of band.

(gpt)zfsboot will read one-time boot directives from a special ZFS pool
area. The area was previously described as "Boot Block Header", but
currently it is know as Pad2, marked as reserved and is zeroed out on
pool creation. The new code interprets data in this area, if any, using
the same format as boot.config. The area is immediately wiped out.
Failure to parse the directives results in a reboot right after the
cleanup. Otherwise the boot sequence proceeds as usual.
zfsbootcfg writes zfsboot arguments specified on its command line to the
Pad2 area of a disk identified by vfs.zfs.boot.primary_pool and
vfs.zfs.boot.primary_vdev kenv variables that are set by loader during
boot. Please see the manual page for more.
Thanks to all who reviewed, contributed and made suggestions! There are

When reading compressed data from disk, the ARC should keep the compressed

uncompressed data should be short-lived allowing the ARC to cache a much larger

If you create a zfs child folder, zfs send returns an error when a recursive
incremental send is done between two snapshots made prior to the folder
creation.
The problem can be reproduced with the following steps.
root@zfs:/# zfs create pool/test
root@zfs:/# zfs snapshot pool/test@snap1
root@zfs:/# zfs snapshot pool/test@snap2
root@zfs:/# zfs create pool/test/child
root@zfs:/# zfs send -R -I pool/test@snap1 pool/test@snap2 > /dev/null
WARNING: could not send pool/test/child@snap2: does not exist
WARNING: could not send pool/test/child@snap2: does not exist
root@zfs:/# echo $?

root@zfs:/# zfs snapshot -r pool/test@snap3

root@zfs:/# echo $?
0
root@zfs:/# zfs send -R -I pool/test@snap2 pool/test@snap3 > /dev/null
root@zfs:/# echo $?
0
Since pool/test/child was created after snap2, zfs send should not expect snap2
to be in pool/test/child when doing a recursive send. It should examine the
compare the creation time of the snapshot and each child folder to decide if
the folder will be sent. The next incremental send between snap2 and snap3
would properly create the child folder and snap3 which first appears in the
child folder.
The problem is identical if '-i' is used instead of '-I'.

Summary of changes:
- Replace all instances of FILES/TESTS with ${PACKAGE}FILES. This ensures that
namespacing is kept with FILES appropriately, and that this shouldn't need
to be repeated if the namespace changes -- only the definition of PACKAGE
needs to be changed
- Allow PACKAGE to be overridden by callers instead of forcing it to always be
`tests`. In the event we get to the point where things can be split up
enough in the base system, it would make more sense to group the tests
with the blocks they're a part of, e.g. byacc with byacc-tests, etc
- Remove PACKAGE definitions where possible, i.e. where FILES wasn't used
previously.
- Remove unnecessary TESTSPACKAGE definitions; this has been elided into

- Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES;
${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk.
- Fix installation of files under data/ subdirectories in lib/libc/tests/hash

At the moment type parameter of lzc_create() is of dmu_objset_type_t type.
That exposes an implementation detail and requires sys/fs/zfs.h to be included
in libzfs_core.h creating unnecessary coupling between libzfs_core interface
and ZFS internals.
I think that dmu_objset_type_t should be replaced with a libzfs_core
enumeration of supported dataset types.
For ABI reasons the new enumeration could be bit-compatible with
dmu_objset_type_t.
For example:
typedef enum {
LZC_DST_ZFS = 2,
LZC_DST_ZVOL
} lzc_dataset_type_t;

This allows one to enable DTrace probes relatively early during boot,
during SI_SUB_DTRACE_ANON, before dtrace(1) can invoked. The desired
enabling is created using dtrace -A, which writes a /boot/dtrace.dof
file and uses nextboot(8) to ensure that DTrace kernel modules are loaded
and that the DOF file describing the enabling is loaded by loader(8)
during the subsequent boot. The trace output can then be fetched with
dtrace -a.
With this commit, boot-time DTrace is only functional on i386 and amd64: on
other architectures, the high-resolution timer frequency is initialized
during SI_SUB_CLOCKS and is thus not available when the anonymous
tracing state is initialized. On x86, the TSC is used and is thus available
earlier.

This allows to do a full (non-incremental send) and receive it as a clone
of an existing dataset. It can leverage nopwrite to share blocks with the
origin. This can be used to change the relationship of datasets on the
target. For example, maybe on the source you have:
A ---- B ---- C
And you have sent to the target a full of B, and the incremental B->C:
B ---- C
You later realize that you want to have A on the target. You will have to
do a full send of A, but nopwrite can save you space on the target if you
receive it as a clone of B, assuming that A and B have some blocks inxi

The script that generates these makefiles was changed to modify LIBADD
rather than LDADD/DPADD, but the makefile itself was also changed in a
slightly different way.
r281257 added support for lazyload mode by allowing dtrace(1) to register
a DOF section on behalf of a traced process. This was implemented by
having libdtrace copy the DOF section into a heap-allocated buffer and
passing its address to the ioctl handler. However, DTrace uses the DOF
section address as a lookup key in certain cases, so the ioctl handler
should be given the target process' DOF section address instead. This
change modifies the ADDDOF handler to copy the DOF section in from the
target process, rather than from dtrace(1).
The proper place for this list is _DP_dtrace.
Due to removing the LDADD_dtrace, more LIBADD are needed in
cddl/usr.sbin/dtrace to prevent underlinking.
This fixes overlinking in cddl/usr.sbin/lockstat and
cddl/usr.sbin/plockstat.

This is not properly respecting WITHOUT or ARCH dependencies in target/.
Doing so requires a massive effort to rework targets/ to do so. A
better approach will be to either include the SUBDIR Makefiles directly
and map to DIRDEPS or just dynamically lookup the SUBDIR. These lose
the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package. The current implementation of targets/ is
very unmaintainable.

Previously, lockstat(1) would use a lock's address as its identifier when
consuming data describing lock contention and hold events. After collecting
the requested data, it would use ksyms(4) to resolve lock addresses to
names. Of course, this doesn't work too well for locks contained in
dynamically-allocated memory. This change modifies lockstat(1) to trace the
lock names obtained from the base struct lock_object instead, leading to
output that is generally much more useful.
This change also removes the -c option, which is used to coalesce data for
locks in an array. It's not possible to support this option without also
tracing lock addresses, and since lock arrays in which the lock names are
distinct are not very common in FreeBSD, it's simpler to just remove the
option.

some ctfmerge crashes that started to occur on i386 weeks after r274569 was

by malformed CTF info that led to a stack overflow. The issue with CTF
info in i386 kernels seems to have been resolved by r261246, which updated
libdwarf and libelf.
r274569 fixes a bug which caused duplicate types to appear in the kernel's
CTF info. This duplication generally does not cause problems when using
DTrace, but makes it easier to hit the limit of 2^15 - 1 distinct type
definitions in a CTF container.

0. For spin events report time spent spinning, not a loop count.
While loop count is much easier and cheaper to obtain it is hard
to reason about the reported numbers, espcially for adaptive locks
where both spinning and sleeping can happen.
So, it's better to compare apples and apples.
1. Teach lockstat about FreeBSD rw locks.
This is done in part by changing the corresponding probes
and in part by changing what probes lockstat should expect.
2. Teach lockstat that rw locks are adaptive and can spin on FreeBSD.
3. Report lock acquisition events for successful rw try-lock operations.
4. Teach lockstat about FreeBSD sx locks.
Reporting of events for those locks completely mirrors
rw locks.
5. Report spin and block events before acquisition event.
This is behavior documented for the upstream, so it makes sense to stick
to it. Note that because of FreeBSD adaptive lock implementations
both the spin and block events may be reported for the same acquisition
while the upstream reports only one of them.
