Rich Ercolani 2e3b3e3a2e Workaround Debian's fake System.map behavior
Debian ships fake System.map files by default, leading to the
invocation of depmod with them to flood you with errors about
missing symbols.

Let's notice and not do that.

José Luis Salvador Rufo a35125e3d5 Proper support for DESTDIR and INSTALL_MOD_PATH
The environment variables DESTDIR and INSTALL_MOD_PATH must
be mutually exclusive.

https://www.gnu.org/prep/standards/html_node/DESTDIR.html
https://www.kernel.org/doc/Documentation/kbuild/modules.txt

This issue was discussed in this Buildroot thread:
https://lists.buildroot.org/pipermail/buildroot/2021-August/621350.html

I saw this behavior in other different projects, as:

- Yocto Project:
  https://www.yoctoproject.org/pipermail/meta-freescale/2013-August/004307.html

- Google IA Coral:
  https://coral.googlesource.com/linux-imx-debian/+/refs/heads/master/debian/rules

For the above reasons, INSTALL_MOD_PATH will be set as DESTDIR
by default.

Brian Behlendorf fe8b0a33d4 ZTS: alloc_class.ksh must wait for the process to exit
The alloc_class_* tests may fail on Linux with an EBUSY error if
`zfs destroy` is run before the `dd` process has had a chance to
terminate.  Wait on the pid after the `kill -9` to make sure.

When testing I didn't observe any failures for the alloc_class
tests.  Remove them from the exceptions list, the CI was used to
verify the tests pass on all platforms.

George Amanakis e257bd481b Introduce a flag to skip comparing the local mac when raw sending
Raw receiving a snapshot back to the originating dataset is currently
impossible because of user accounting being present in the originating
dataset.

One solution would be resetting user accounting when raw receiving on
the receiving dataset. However, to recalculate it we would have to dirty
all dnodes, which may not be preferable on big datasets.

Instead, we rely on the os_phys flag
OBJSET_FLAG_USERACCOUNTING_COMPLETE to indicate that user accounting is
incomplete when raw receiving. Thus, on the next mount of the receiving
dataset the local mac protecting user accounting is zeroed out.
The flag is then cleared when user accounting of the raw received
snapshot is calculated.

Mark Johnston 0da15f9194 Fix handling of errors from dmu_write_uio_dbuf() on FreeBSD
FreeBSD's implementation of zfs_uio_fault_move() returns EFAULT when a
page fault occurs while copying data in or out of user buffers.  The VFS
treats such errors specially and will retry the I/O operation (which may
have made some partial progress).

When the FreeBSD and Linux implementations of zfs_write() were merged,
the handling of errors from dmu_write_uio_dbuf() changed such that
EFAULT is not handled as a partial write.  For example, when appending
to a file, the z_size field of the znode is not updated after a partial
write resulting in EFAULT.

Restore the old handling of errors from dmu_write_uio_dbuf() to fix
this.  This should have no impact on Linux, which has special handling
for EFAULT already.

Mark Johnston 5303fc4c95 Avoid memory allocations in the ARC eviction thread
When the eviction thread goes to shrink an ARC state, it allocates a set
of marker buffers used to hold its place in the state's sublists.

This can be problematic in low memory conditions, since
1) the allocation can be substantial, as we allocate NCPU markers;
2) on at least FreeBSD, page reclamation can block in
   arc_wait_for_eviction()

In particular, in stress tests it's possible to hit a deadlock on
FreeBSD when the number of free pages is very low, wherein the system is
waiting for the page daemon to reclaim memory, the page daemon is
waiting for the ARC eviction thread to finish, and the ARC eviction
thread is blocked waiting for more memory.

Try to reduce the likelihood of such deadlocks by pre-allocating markers
for the eviction thread at ARC initialization time.  When evicting
buffers from an ARC state, check to see if the current thread is the ARC
eviction thread, and use the pre-allocated markers for that purpose
rather than dynamically allocating them.

Brian Behlendorf 6575defc52 Verify dRAID empty sectors
Verify that all empty sectors are zero filled before using them to
calculate parity.  Failure to do so can result in incorrect parity
columns being generated and written to disk if the contents of an
empty sector are non-zero.  This was possible because the checksum
only protects the data portions of the buffer, not the empty sector
padding.

This issue has been addressed by updating raidz_parity_verify() to
check that all dRAID empty sectors are zero filled.  Any sectors
which are non-zero will be fixed, repair IO issued, and a checksum
error logged.  They can then be safely used to verify the parity.

This specific type of damage is unlikely to occur since it requires
a disk to have silently returned bad data, for an empty sector, while
performing a scrub.  However, if a pool were to have been damaged
in this way, scrubbing the pool with this change applied will repair
both the empty sector and parity columns as long as the data checksum
is valid.  Checksum errors will be reported in the `zpool status`
output for any repairs which are made.

This commit resolves the issue by moving the acquisition of the
spa_namespace_lock back to after the zv_suspend_lock which restores
the original ordering.

Additionally, as part of this change the error exit paths were
simplified where possible.

Alan Somers 4b2bac5fe9 FreeBSD: Update argument types for VOP_READDIR
A recent commit to FreeBSD changed the type of
vop_readdir_args.a_cookies to a uint64_t**.  There is no functional
impact to ZFS because ZFS only uses 32-bit cookies, which will be
zero-extended to 64-bits by the existing code.

Alexander Motin 786abf5321 Reduce number of arc_prune threads
On FreeBSD vnode reclamation is single-threaded, protected by single
global lock.  Linux seems to be able to use a thread per mount point,
but at this time it creates more harm than good.

Reduce number of threads to 1, adding tunable in case somebody wants
to try more.

Ryan Moeller 913ae45218 FreeBSD: Provide correct file generation number
va_seq was actually a thin veil over va_gen, so z_gen is a more
appropriate value than z_seq to populate the field with.

Drop the unnecessary compat obfuscation and provide the correct
file generation number.

Mark Johnston 19337332cc Fix several bugs in the FreeBSD rename VOP implementation
- To avoid a use-after-free, zfsvfs->z_log needs to be loaded after the
  teardown lock is acquired with ZFS_ENTER().
- Avoid leaking vnode locks in zfs_rename_relock() and zfs_rename_()
  when the ZFS_ENTER() macros forces an early return.

Refactor the rename implementation so that ZFS_ENTER() can be used
safely.  As a bonus, this lets us use the ZFS_VERIFY_ZP() macro instead
of open-coding its implementation.

Note that jumping to the "out" label, "error" is always non-zero.

Brian Behlendorf 6ed7d77b44 ZTS: import_rewind_device_replaced reliably fails
The import_rewind_device_replaced.ksh test was never entirely reliable
because it depends on MOS data not being overwritten.  The MOS data is
not protected by the snapshot so occasional failures were always
expected.  However, this test is now failing reliably on all platforms
indicating something has changed in the code since the test was marked
"maybe".  Convert the test to a "known" failure until the root cause
is identified and resolved.
