Richard Yao 834815e9f7 Implement --enable-debuginfo to force debuginfo
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.

Richard Yao 0f1ff38476 Make --enable-debug fail when given bogus args
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.

When used in conjunction with one of '-e' or '-d' zfs receive options

Brian Behlendorf 137b3e6cff Extend zloop.sh for automated testing
In order to debug issues encountered by ztest during automated
testing it's important that as much debugging information as
possible by dumped at the time of the failure.  The following
changes extend the zloop.sh script in order to make it easier
to integrate with buildbot.

* Add the `-m <maximum cores>` option to zloop.sh to place a
  limit of the number of core dumps generated.  By default, the
  existing behavior is maintained and no limit is set.

* Add the `-l` option to create a 'ztest.core.N' symlink in the
  current directory to the core directory. This functionality
  is provided primarily for buildbot which expects log files to
  have well known names.

* Rename 'ztest.ddt' to 'ztest.zdb' and extend it to dump
  additional basic information on failure for latter analysis.

Richard Yao ecc8af1812 Fix incompatibility with Reiser4 patched kernels
In ZFSOnLinux, our sources and build system are self contained such that
we do not need to make changes to the Linux kernel sources. Reiser4 on
the other hand exists solely as a kernel tree patch and opts to make
changes to the kernel rather than adapt to it. After Linux 4.1 made a
VFS change that replaced new_sync_read with do_sync_read, Reiser4's
maintainer decided to modify the kernel VFS to export the old function.
This caused our autotools check to misidentify the kernel API as
predating Linux 4.1 on kernels that have been patched with Reiser4
support, which breaks our build.

Reiser4 really should be patched to stop doing this, but lets modify our
check to be more strict to help the affected users of both filesystems.

Also, we were not checking the types of arguments and return value of
new_sync_read() and new_sync_write() . Lets fix that too.

Alex Zhuravlev 129e3e8dc3 Use zap_count instead of cached z_size for unlink
As a performance optimization Lustre does not strictly update
the SA_ZPL_SIZE when adding/removing from non-directory entries.
This results in entries which cannot be removed through the ZPL
layer even though the ZAP is empty and safe to remove.

Resolve this issue by checking the zap_count() directly instead
on relying on the cached SA_ZPL_SIZE.  Micro-benchmarks show no
significant performance impact due to the additional overhead
of using zap_count().

Brian Behlendorf 9c1a8eaa51 Fix ARC hit rate
When the compressed ARC feature was added in commit d3c2ae1
the method of reference counting in the ARC was modified.  As
part of this accounting change the arc_buf_add_ref() function
was removed entirely.

This would have be fine but the arc_buf_add_ref() function
served a second undocumented purpose of updating the ARC access
information when taking a hold on a dbuf.  Without this logic
in place a cached dbuf would not migrate its associated
arc_buf_hdr_t to the MFU list.  This would negatively impact
the ARC hit rate, particularly on systems with a small ARC.

This change reinstates the missing call to arc_access() from
dbuf_hold() by implementing a new arc_buf_access() function.

         replacing-0             DEGRADED     0     0     0
           /var/tmp/fault-dev    UNAVAIL      0     0     0  cannot open
           /var/tmp/replace-dev  ONLINE       0     0     0

   spares
     /var/tmp/spare-dev1         INUSE     currently in use

This is safe and allowed, but get_replication() needs to handle this
situation gracefully to let zpool add new devices to the pool.

lidongyang 8d82a19def Call commit callbacks from the tail of the list
Our zfs backed Lustre MDT had soft lockups while under heavy metadata
workloads while handling transaction callbacks from osd_zfs.

The problem is zfs is not taking advantage of the fast path in
Lustre's trans callback handling, where Lustre will skip the calls
to ptlrpc_commit_replies() when it already saw a higher transaction
number.

This patch corrects this, it also has a positive impact on metadata
performance on Lustre with osd_zfs, plus some cleanup in the headers.

A similar issue for ext4/ldiskfs is described on:

Brian Behlendorf 504bfc8b49 Fix multihost stale cache file import
When the multihost property is enabled it should be impossible to
import an active pool even using the force (-f) option.  This patch
prevents a forced import from succeeding when importing with a
stale cache file.

The root cause of the problem is that the kernel modules trusted
the hostid provided in configuration.  This is always correct when
the configuration is generated by scanning for the pool.  However,
when using an existing cache file the hostid could be stale which
would result in the activity check being skipped.

Resolve the issue by always using the hostid read from the label
configuration where the best uberblock was found.

Olaf Faaland 53a8cbd70e Fix ZTS MMP tests and ztest -M behavior
Quote "$MMP_IMPORT_MSG" when it is passed as an argument, as it is a
multi-word string.  Some tests were passing when they should not have,
because the grep was only testing for the first word.

Correct the message expected when no hostid is set and the test attempts
to enable multihost.  It did not match the actual output in that
situation.

Disable ztest_reguid() when ztest is invoked with the -M option.  If
ztest performs a reguid, a concurrent import attempt may fail with the
error "one or more devices is currently unavailable" if the guid sum is
calculated on the original device guids but compared against the guid
sum ztest wrote based on the new device guids.

Brian Behlendorf 1030f807ba Fix NFS sticky bit permission denied error
When zfs_sticky_remove_access() was originally adapted for Linux
a typo was made which altered the intended behavior.  As described
in the block comment, the intended behavior is that permission
should be granted when the entry is a regular file and you have
write access.  That is, S_ISREG should have been used instead of
S_ISDIR.

Restricting permission to regular files made good sense for older
systems where setting the bit on executable files would instruct
the system to save the program's text segment on the swap device.

On modern systems this behavior has been replaced by the sticky
bit acting as a restricted deletion flag and the plain file
restriction has been relaxed.

because the itx->itx_lr.lrc_reclen field is not constant from
allocation to free.  Using a different itx->itx_lr.lrc_reclen
size in zio_data_buf_free() can result in the allocation being
returned to the wrong kmem cache.

This issue can be avoided entirely by storing the allocation size
in itx->itx_size and using that for zio_data_buf_free().

Richard Laager 68ba1d2fa9 initramfs: Honor canmount=off
The initramfs script was not honoring canmount=off.  With this change,
it does.  If the administrator has asked that a filesystem not be
mounted, that should be honored.

As an exception, the initramfs script ignores canmount=off on the
rootfs.  The rootfs should not have canmount=off set either.  However,
mounting it anyway seems harmless because it is being asked for
explicitly.  The point of this exception is to avoid the risk of
breaking existing systems, just in case someone has canmount=off set on
their rootfs.

The initramfs still mounts filesystems with canmount=noauto.  This is
necessary because it is typical to set that on the rootfs so that it can
be cloned.  Without canmount=noauto, the clones' duplicate mountpoints
would conflict.

This is the remainder of the fix for:
