Subject: [PATCH] Make --enable-debug fail when given bogus args
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Currently, bogus options to --enable-debug become --disable-debug. That
means that passing --enable-debug=true is analogous to --disable-debug,
but the result is counterintuitive. We switch to AS_CASE to allow us to
fail when given a bogus option.
Also, we modify the text printed to clarify that --enable-debug enables
assertions.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Implement --enable-debuginfo to force debuginfo
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Inspection of a Ubuntu 14.04 x64 system revealed that the config file
used to build the kernel image differs from the config file used to
build kernel modules by the presence of CONFIG_DEBUG_INFO=y:
This in itself is insufficient to show that the kernel is built with
debuginfo, but a cursory analysis of the debuginfo provided and the
size of the kernel strongly suggests that it was built with
CONFIG_DEBUG_INFO=y while the modules were not. Installing
linux-image-$(uname -r)-dbgsym had no obvious effect on the debuginfo
provided by either the modules or the kernel.
The consequence is that issue reports from distributions such as Ubuntu
and its derivatives build kernel modules without debuginfo contain
nonsensical backtraces. It is therefore desireable to force generation
of debuginfo, so we implement --enable-debuginfo. Since the build system
can build both userspace components and kernel modules, the generic
--enable-debuginfo option will force debuginfo for both. However, it
also supports --enable-debuginfo=kernel and --enable-debuginfo=user for
finer grained control.
Enabling debuginfo for the kernel modules works by injecting
CONFIG_DEBUG_INFO=y into the make environment. This is enables
generation of debuginfo by the kernel build systems on all Linux
kernels, but the build environment is slightly different int hat
CONFIG_DEBUG_INFO has not been in the CPP. Adding -DCONFIG_DEBUG_INFO
would fix that, but it would also cause build failures on kernels where
CONFIG_DEBUG_INFO=y is already set. That would complicate its use in
DKMS environments that support a range of kernels and is therefore
undesireable. We could write a compatibility shim to enable
CONFIG_DEBUG_INFO only when it is explicitly disabled, but we forgo
doing that because it is unnecessary. Nothing in ZoL or the kernel uses
CONFIG_DEBUG_INFO in the CPP at this time and that is unlikely to
change.
Enabling debuginfo for the userspace components is done by injecting -g
into CPPFLAGS. This is not necessary because the build system honors the
environment's CPPFLAGS by appending them to the actual CPPFLAGS used,
but it is supported for consistency.

Subject: [PATCH] Make "-fno-inline" compile option more accessible
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When functions are inlined, it can make the system much more difficult
to instrument using tools such as ftrace, BPF, crash, etc. Thus, to aid
development and increase the system's observability, when the
"--enable-debuginfo" flag is specified, the "-fno-inline" compilation
option will be used for both userspace and kernel modules.

Subject: [PATCH] Add support for "--enable-code-coverage" option
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This change adds support for a new option that can be passed to the
configure script: "--enable-code-coverage". Further, the "--enable-gcov"
option has been removed, as this new option provides the same
functionality (plus more).
When using this new option the following make targets are available:
* check-code-coverage
* code-coverage-capture
* code-coverage-clean
Note: these make targets can only be run from the root of the project.

+# ===========================================================================
+# https://www.gnu.org/software/autoconf-archive/ax_code_coverage.html
+# ===========================================================================
+#
+# SYNOPSIS
+#
+# AX_CODE_COVERAGE()
+#
+# DESCRIPTION
+#
+# Defines CODE_COVERAGE_CPPFLAGS, CODE_COVERAGE_CFLAGS,
+# CODE_COVERAGE_CXXFLAGS and CODE_COVERAGE_LIBS which should be included
+# in the CPPFLAGS, CFLAGS CXXFLAGS and LIBS/LIBADD variables of every
+# build target (program or library) which should be built with code
+# coverage support. Also defines CODE_COVERAGE_RULES which should be
+# substituted in your Makefile; and $enable_code_coverage which can be
+# used in subsequent configure output. CODE_COVERAGE_ENABLED is defined
+# and substituted, and corresponds to the value of the
+# --enable-code-coverage option, which defaults to being disabled.
+#
+# Test also for gcov program and create GCOV variable that could be
+# substituted.
+#
+# Note that all optimization flags in CFLAGS must be disabled when code
+# coverage is enabled.
+#
+# Usage example:
+#
+# configure.ac:
+#
+# AX_CODE_COVERAGE
+#
+# Makefile.am:
+#
+# @CODE_COVERAGE_RULES@
+# my_program_LIBS = ... $(CODE_COVERAGE_LIBS) ...
+# my_program_CPPFLAGS = ... $(CODE_COVERAGE_CPPFLAGS) ...
+# my_program_CFLAGS = ... $(CODE_COVERAGE_CFLAGS) ...
+# my_program_CXXFLAGS = ... $(CODE_COVERAGE_CXXFLAGS) ...
+#
+# This results in a "check-code-coverage" rule being added to any
+# Makefile.am which includes "@CODE_COVERAGE_RULES@" (assuming the module
+# has been configured with --enable-code-coverage). Running `make
+# check-code-coverage` in that directory will run the module's test suite
+# (`make check`) and build a code coverage report detailing the code which
+# was touched, then print the URI for the report.
+#
+# In earlier versions of this macro, CODE_COVERAGE_LDFLAGS was defined
+# instead of CODE_COVERAGE_LIBS. They are both still defined, but use of
+# CODE_COVERAGE_LIBS is preferred for clarity; CODE_COVERAGE_LDFLAGS is
+# deprecated. They have the same value.
+#
+# This code was derived from Makefile.decl in GLib, originally licenced
+# under LGPLv2.1+.

Update the codecov.yml to make the following functional changes.
* Do not require the CI testing to pass before posting results.
* Set red-yellow-green coverage percent from 50%-100%
* Allow a 1% drop in coverage to still be considered a pass.
* Reduce the size of the comment posted to the issue.
Additionally, the top level README.markdown has been updated
to include the codecov.io badge and the project summary reworded.

Subject: [PATCH] Remove vn_rename and vn_remove dependency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The only place vn_rename and vn_remove are used is when writing
out an updated pool configuration file. By truncating the file
instead of renaming and removing it we can avoid having to implement
these interfaces entirely. Functionally an empty cache file is
treated the same as a missing cache file. This is particularly
advantageous because the Linux kernel has never provided a way
to reliably implement vn_rename and vn_remove.
The cachefile_004_pos.ksh test case was updated to understand
that an empty cache file is the same as a missing one.
The zfs-import-* systemd service files were not updated to use
ConditionFileNotEmpty in place of ConditionPathExists. This
means that after exporting all pools and rebooting new pools
will not the scanned for on the next boot. This small change
should not impact normal usage since pools are not exported
as part of a normal shutdown.
Documentation was updated accordingly.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The function that fills the uberblock ring buffer on every device label
has been reworked to avoid occasional failures caused by a race
condition that prevents 'zpool sync' from writing some uberblock
sequentially: this happens when the pool sync ioctl dispatch code calls
txg_wait_synced() while we're already waiting for a TXG to sync.

Subject: [PATCH] Fix systemd_ RPM macros usage on Debian-based distributions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Debian-based distributions do not seem to provide RPM macros for
dealing with systemd pre- and post- (un)install actions: this results
in errors when installing or upgrading .deb packages because the
resulting control scripts contain the following unresolved macros:
* %systemd_post
* %systemd_preun
* %systemd_postun
Fix this by providing default values for postinstall, preuninstall and
postuninstall scripts when these macros are not defined.

Subject: [PATCH] Linux 4.16 compat: inode_set_iversion()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
A new interface was added to manipulate the version field of an
inode. Add a inode_set_iversion() wrapper for older kernels and
use the new interface when available.
The i_version field was dropped from the trace point due to the
switch to an atomic64_t i_version type.

Related to commit 4859fe796, when directly using the kernel's
refcount functions in kernel compatibility code do not map
refcount_t to zfs_refcount_t. This leads to a type mismatch.
Longer term we should consider renaming refcount_t to
zfs_refcount_t in the zfs code base.

Subject: [PATCH] Fix zdb -c traverse stop on damaged objset root
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If a corruption happens to be on a root block of an objset, zdb -c will
not correctly report the error, and it will not traverse the datasets
that come after. This is because traverse_visitbp, which does the
callback and reset error for TRAVERSE_HARD, is skipped when traversing
zil is failed in traverse_impl.
Here's example of what 'zdb -eLcc' command looks like on a pool with
damaged objset root:

Subject: [PATCH] Fix zdb -R decompression
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There are some issues in the zdb -R decompression implementation.
The first is that ZLE can easily decompress non-ZLE streams. So we add
ZDB_NO_ZLE env to make zdb skip ZLE.
The second is the random bytes appended to pabd, pbuf2 stuff. This serve
no purpose at all, those bytes shouldn't be read during decompression
anyway. Instead, we randomize lbuf2, so that we can make sure
decompression fill exactly to lsize by bcmp lbuf and lbuf2.
The last one is the condition to detect fail is wrong.

Subject: [PATCH] Fix zdb -ed on objset for exported pool
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
zdb -ed on objset for exported pool would failed with:
failed to own dataset 'qq/fs0': No such file or directory
The reason is that zdb pass objset name to spa_import, it uses that
name to create a spa. Later, when dmu_objset_own tries to lookup the spa
using real pool name, it can't find one.
We fix this by make sure we pass pool name rather than objset name to
spa_import.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
With "casesensitivity=mixed", zap_add() could fail when the number of
files/directories with the same name (varying in case) exceed the
capacity of the leaf node of a Fatzap. This results in a ASSERT()
failure as zfs_link_create() does not expect zap_add() to fail. The fix
is to handle these failures and rollback the transactions.

+# DESCRIPTION:
+# For the filesystem with casesensitivity=mixed, normalization=none,
+# when multiple files with the same name (differing only in case) are created,
+# the number of files is limited to what can fit in a fatzap leaf-block.
+# And beyond that, it fails with ENOSPC.
+#
+# Ensure that the create/rename operations fail gracefully and not trigger an
+# ASSERT.
+#
+# STRATEGY:
+# Repeat the below steps for objects: files, directories, symlinks and hardlinks
+# 1. Create objects with same name but varying in case.
+# E.g. 'abcdefghijklmnop', 'Abcdefghijklmnop', 'ABcdefghijklmnop' etc.
+# The create should fail with ENOSPC.
+# 2. Create an object with name 'tmp_obj' and try to rename it to name that we
+# failed to add in step 1 above.
+# This should fail as well.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

When upgrading from the distribution-provided zfs-initramfs package on

Subject: [PATCH] 'zfs receive' fails with "dataset is busy"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Receiving an incremental stream after an interrupted "zfs receive -s"
fails with the message "dataset is busy": this is because we still have
the hidden clone ../%recv from the resumable receive.
Improve the error message suggesting the existence of a partially
complete resumable stream from "zfs receive -s" which can be either
aborted ("zfs receive -A") or resumed ("zfs send -t").

Subject: [PATCH] OpenZFS 8857 - zio_remove_child() panic due to already
destroyed parent zio
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
PROBLEM
=======
It's possible for a parent zio to complete even though it has children
which have not completed. This can result in the following panic:

The problem is that dbuf_prefetch along with l2arc can create a zio tree
which confuses the parent zio and allows it to complete with while children
still exist. Here's the scenario:
zio tree:
pio
|--- lio
The parent zio, pio, has entered the zio_done stage and begins to check its
children to see there are still some that have not completed. In zio_done(),
the children are checked in the following order:
zio_wait_for_children(zio, ZIO_CHILD_VDEV, ZIO_WAIT_DONE)
zio_wait_for_children(zio, ZIO_CHILD_GANG, ZIO_WAIT_DONE)
zio_wait_for_children(zio, ZIO_CHILD_DDT, ZIO_WAIT_DONE)
zio_wait_for_children(zio, ZIO_CHILD_LOGICAL, ZIO_WAIT_DONE)
If pio, finds any child which has not completed then it stops executing and
goes to sleep. Each call to zio_wait_for_children() will grab the io_lock
while checking the particular child.
In this scenario, the pio has completed the first call to
zio_wait_for_children() to check for any ZIO_CHILD_VDEV children. Since
the only zio in the zio tree right now is the logical zio, lio, then it
completes that call and prepares to check the next child type.
In the meantime, the lio completes and in its callback creates a child vdev
zio, cio. The zio tree looks like this:
zio tree:
pio
|--- lio
|--- cio
The lio then grabs the parent's io_lock and removes itself.
zio tree:
pio
|--- cio
The pio continues to run but has already completed its check for ZIO_CHILD_VDEV
and will erroneously complete. When the child zio, cio, completes it will panic
the system trying to reference the parent zio which has been destroyed.
SOLUTION
========
The fix is to rework the zio_wait_for_children() logic to accept a bitfield
for all the children types that it's interested in checking. The
io_lock will is held the entire time we check all the children types. Since
the function now accepts a bitfield, a simple ZIO_CHILD_BIT() macro is provided
to allow for the conversion between a ZIO_CHILD type and the bitfield used by
the zio_wiat_for_children logic.

Subject: [PATCH] Fix config issues: frame size and headers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
1. With various (debug and/or tracing?) kernel options enabled it's
possible for 'struct inode' and 'struct super_block' to exceed the
default frame size, leaving errors like this in config.log:
build/conftest.c:116:1: error: the frame size of 1048 bytes is larger
than 1024 bytes [-Werror=frame-larger-than=]
Fix this by removing the frame size warning for config checks
2. Without the correct headers included, it's possible for declarations
to be missed, leaving errors like this in the config.log:
build/conftest.c:131:14: error: ‘struct nameidata’ declared inside
parameter list [-Werror]
Fix this by adding appropriate headers.
Note: Both these issues can result in silent config failures because
the compile failure is taken to mean "this option is not supported by
this kernel" rather than "there's something wrong with the config
test". This can lead to something merely annoying (compile failures) to
something potentially serious (miscompiled or misused kernel primitives
or functions). E.g. the fixes included here resulted in these
additional defines in zfs_config.h with linux v4.14.19:
Also, drive-by whitespace fixes in config/* files which don't mention
"GNU" (those ones look to be imported from elsewhere so leave them
alone).

A log_must call was causing count_uberblocks to return more

overwriting MMP blocks written by host B, and the blocks written by

Subject: [PATCH] Fix free memory calculation on v3.14+
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Provide infrastructure to auto-configure to enum and API changes in the
global page stats used for our free memory calculations.
arc_free_memory has been broken since an API change in Linux v3.14:
2016-07-28 v4.8 599d0c95 mm, vmscan: move LRU lists to node
2016-07-28 v4.8 75ef7184 mm, vmstat: add infrastructure for per-node
vmstats
These commits moved some of global_page_state() into
global_node_page_state(). The API change was particularly egregious as,
instead of breaking the old code, it silently did the wrong thing and we
continued using global_page_state() where we should have been using
global_node_page_state(), thus indexing into the wrong array via
NR_SLAB_RECLAIMABLE et al.
There have been further API changes along the way:
2017-07-06 v4.13 385386cf mm: vmstat: move slab statistics from zone to
node counters
2017-09-06 v4.14 c41f012a mm: rename global_page_state to
global_zone_page_state
...and various (incomplete, as it turns out) attempts to accomodate
these changes in ZoL:
2017-08-24 2209e409 Linux 4.8+ compatibility fix for vm stats
2017-09-16 787acae0 Linux 3.14 compat: IO acct, global_page_state, etc
2017-09-19 661907e6 Linux 4.14 compat: IO acct, global_page_state, etc
The config infrastructure provided here resolves these issues going back
to the original API change in v3.14 and is robust against further Linux
changes in this area.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Tony Hutter <hutter2@llnl.gov>
Date: Fri, 23 Feb 2018 11:38:05 -0800
Subject: [PATCH] Add scrub after resilver zed script
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
* Add a zed script to kick off a scrub after a resilver. The script is
disabled by default.
* Add a optional $PATH (-P) option to zed to allow it to use a custom
$PATH for its zedlets. This is needed when you're running zed under
the ZTS in a local workspace.
* Update test scripts to not copy in all-debug.sh and all-syslog.sh by
default. They can be optionally copied in as part of zed_setup().
These scripts slow down zed considerably under heavy events loads and
can cause events to be dropped or their delivery delayed. This was
causing some sporadic failures in the 'fault' tests.

Subject: [PATCH] Add SMART self-test results to zpool status -c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Add in SMART self-test results to zpool status|iostat -c. This
works for both SAS and SATA drives.
Also, add plumbing to allow the 'smart' script to take smartctl
output from a directory of output text files instead of running
it against the vdevs.

Subject: [PATCH] Increment zil_itx_needcopy_bytes properly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In zil_lwb_commit() with TX_WRITE, we copy the log write record (lrw)
into the log write block (lwb) and send it off using zil_lwb_add_txg().
If we also have WR_NEED_COPY, we additionally copy the lwr's data into
the lwb to be sent off. If the lwr + data doesn't fit into the lwb, we
send the lrw and as much data as will fit (dnow bytes), then go back
and do the same with the remaining data.
Each time through this loop we're sending dnow data bytes. I.e.
zil_itx_needcopy_bytes should be incremented by dnow.

Subject: [PATCH] Change checksum & IO delay ratelimit values
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Change checksum & IO delay ratelimit thresholds from 5/sec to 20/sec.
This allows zed to actually trigger if a bunch of these events arrive in
a short period of time (zed has a threshold of 10 events in 10 sec).
Previously, if you had, say, 100 checksum errors in 1 sec, it would get
ratelimited to 5/sec which wouldn't trigger zed to fault the drive.
Also, convert the checksum and IO delay thresholds to module params for
easy testing.

Subject: [PATCH] Detect long config lock acquisition in mmp
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If something holds the config lock as a writer for too long, MMP will
fail to issue MMP writes in a timely manner. This will result either in
the pool being suspended, or in an extreme case, in the pool not being
protected.
If the time to acquire the config lock exceeds 1/10 of the minimum
zfs_multihost_interval, report it in the zfs debug log.

Subject: [PATCH] Take user namespaces into account in policy checks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Change file related checks to use user namespaces and make
sure involved uids/gids are mappable in the current
namespace.
Note that checks without file ownership information will
still not take user namespaces into account, as some of
these should be handled via 'zfs allow' (otherwise root in a
user namespace could issue commands such as `zpool export`).
This also adds an initial user namespace regression test
for the setgid bit loss, with a user_ns_exec helper usable
in further tests.
Additionally, configure checks for the required user
namespace related features are added for:
* ns_capable
* kuid/kgid_has_mapping()
* user_ns in cred_t

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: LOLi <loli10K@users.noreply.github.com>
Date: Fri, 9 Mar 2018 22:52:37 +0100
Subject: [PATCH] Fix zfs-kmod builds when using rpm >= 4.14
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
With rpm-software-management/rpm@5e94633 a package version containing
invalid characters (most commonly a double '-') causes the kmod package
generation to terminate with an error. This change takes advantage of
the newly introduced rpm macro "_wrong_version_format_terminate_build"
to allow kmod packages to be built.

Subject: [PATCH] Handle zio_resume and mmp => off
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When multihost is disabled on a pool, and the pool is resumed via zpool
clear, within a single cycle of the mmp thread's loop (e.g. while it's
in the cv_timedwait call), both mmp_last_write and mmp_delay should be
updated.
The original code mistakenly treated the two cases as if they could not
occur at the same time.

Subject: [PATCH] Fix MMP write frequency for large pools
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When a single pool contains more vdevs than the CONFIG_HZ for
for the kernel the mmp thread will not delay properly. Switch
to using cv_timedwait_sig_hires() to handle higher resolution
delays.
This issue was reported on Arch Linux where HZ defaults to only
100 and this could be fairly easily reproduced with a reasonably
large pool. Most distribution kernels set CONFIG_HZ=250 or
CONFIG_HZ=1000 and thus are unlikely to be impacted.

-# DESCRIPTION:
-# For the filesystem with casesensitivity=mixed, normalization=none,
-# when multiple files with the same name (differing only in case) are created,
-# the number of files is limited to what can fit in a fatzap leaf-block.
-# And beyond that, it fails with ENOSPC.
-#
-# Ensure that the create/rename operations fail gracefully and not trigger an
-# ASSERT.
-#
-# STRATEGY:
-# Repeat the below steps for objects: files, directories, symlinks and hardlinks
-# 1. Create objects with same name but varying in case.
-# E.g. 'abcdefghijklmnop', 'Abcdefghijklmnop', 'ABcdefghijklmnop' etc.
-# The create should fail with ENOSPC.
-# 2. Create an object with name 'tmp_obj' and try to rename it to name that we
-# failed to add in step 1 above.
-# This should fail as well.
