7386 zfs get does not work properly with bookmarks
illumos/illumos-gate@edb901aab9edb901aab9https://www.illumos.org/issues/7386
The zfs get command does not work with the bookmark parameter while it works
properly with both filesystem and snapshot:
# zfs get -t all -r creation rpool/test
NAME PROPERTY VALUE SOURCE
rpool/test creation Fri Sep 16 15:00 2016 -
rpool/test@snap creation Fri Sep 16 15:00 2016 -

# zfs get -t all -r creation rpool/test@snap

rpool/test@snap creation Fri Sep 16 15:00 2016 -
# zfs get -t all -r creation rpool/test#bkmark
cannot open 'rpool/test#bkmark': invalid dataset name
#
The zfs get command should be modified to work properly with bookmarks too.

This change introduces a new weighting algorithm to improve metaslab selection
.
The new weighting algorithm relies on the SPACEMAP_HISTOGRAM feature. As a res
ult,
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 hel
p
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:
> c5ec000::print zio_t io_alloc_list | ::walk list | ::metaslab_trace
MSID DVA ASIZE WEIGHT RESULT VDEV
- 0 400 0 NOT_ALLOCATABLE ztest.0a
- 0 400 0 NOT_ALLOCATABLE ztest.0a
- 0 400 0 ENOSPC ztest.0a
- 0 200 0 NOT_ALLOCATABLE ztest.0a
- 0 200 0 NOT_ALLOCATABLE ztest.0a
- 0 200 0 ENOSPC ztest.0a
1 0 400 1 x 8M 17b1a00 ztest.0a
> 1ff2400::print zio_t io_alloc_list | ::walk list | ::metaslab_trace
MSID DVA ASIZE WEIGHT RESULT VDEV
- 0 200 0 NOT_ALLOCATABLE mirror-2
- 0 200 0 NOT_ALLOCATABLE mirror-0
1 0 200 1 x 4M 112ae00 mirror-1
- 1 200 0 NOT_ALLOCATABLE mirror-2
- 1 200 0 NOT_ALLOCATABLE mirror-0
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.

Fix DTrace TCP tracepoints to not use mtod() as it is both unnecessary and
dangerous. Those wanting data from an mbuf should use DTrace itself to get
the data.
Add an mbuf to ipinfo_t translator to finish cleanup of mbuf passing to TCP probes.
After some ZIL changes 6 years ago zil_slog_limit got partially broken
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.

Convert ipv4_flags and ipv4_offset fields into host byte order.
Also save only high bits in the ipv4_flags, because it is defined

On FreeBSD there is a setsockopt option SO_USER_COOKIE which allows
setting a 32 bit value on each socket. This can be used by applications
and DTrace as a rendezvous point so that an applicaton's data can
more easily be captured at run time. Expose the user cookie via
DTrace by updating the translator in tcp.d and add a quick test
program, a TCP server, that sets the cookie on each connection

When reading compressed data from disk, the ARC should keep the compressed
block cached and only decompress it when consumers access the block. The
uncompressed data should be short-lived allowing the ARC to cache a much larger
amount of data. The DMU would also maintain a smaller cache of uncompressed
blocks to minimize the impact of decompressing frequently accessed blocks.

6111 zfs send should ignore datasets created after the ending snapshot

https://www.illumos.org/issues/6111
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:/# zfs send -R -I pool/test@snap1 pool/test@snap3 > /dev/null
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'.
