Brian Behlendorf bda31592bf Merge branch 'linux-have-mlslabel' into refs/top-bases/linux-zfs-branch 2010-07-22 16:57:57 -07:00
Brian Behlendorf 66b2805477 Disable mlslabel support in Linux
The ZFS update to onnv_141 brought with it support for a
security label attribute called mlslabel.  This feature
depends on zones to work correctly and thus I am disabling
it under Linux.  Equivilant functionality could be added
at some point in the future.

Brian Behlendorf c979e4bdf8 Move mlslabel hunk to new linux-have-mlslabel
Simply relocate this hunk with a little tweak to the new
linux-have-mlslabel topic branch which has been created to
disable this support on linux.

Brian Behlendorf 0e533b7459 Best effort for minor device removal.
We should just make a best effort when removing zvol minors
from the system during destroy.  Failure here should never
prevent the pool from being destroyed.  For example, if a
pool is so heavily damaged it cannot be opened (part of the
minor removal) we still want to be able to destroy it.  The
worst case here is we may orphan a few minors but even that
is unlikely and not particularly harmful.

Brian Behlendorf 1a493a9555 Add vdev_state to common post info
This was done because there are now lots of resource.fs.zfs.statechange
events being posted but they do not include the state.  For the moment
the state must always be healthy but there's no harm in making this
explicit.

Brian Behlendorf f275e82de9 Add FM_EREPORT_TIME when event is posted
Previously I was adding the FM_EREPORT_TIME time when the nvlist
was constructed.  However, with the update to onnv_141 these
ereport nvlists are now constructed in several places and it
doesn't make sense for each of them to have to add this common
bit of info.  To handle this the FM_EREPORT_TIME is now only
added once when the event is posted.

Ricardo M. Correia 10d4848350 Display DEBUG keyword during module load when --enable-debug is used.
Just to be clear this only indicates that the ZFS code was built
with or without debugging enabled.  It says nothing about about
how the SPL was built, they can be build differently by design.

Brian Behlendorf 99d3042bc8 Update to use reworked SPL debugging
This change updates the ZFS code to use the slightly reworked
SPL debug infrastructure.  It also explicitly sets all ZFS
dprintf debugging to use the SS_USER1 subsystem for logging
in the SPL debug log.

Brian Behlendorf 49c7595ad8 Replace SBUG with PANIC macro
The SBUG macro has been removed from the SPL and replaced
with PANIC which is closer to an existing API.  Simply
update the usage in vdev_disk.c.

Brian Behlendorf fc3e47c6d4 Corrently handle return code in blk_end_request_x
This was caught under Debian Lenny builds because they are one of
the few/only current distros based on a 2.6.26 kernel.  In one
of the build conditionals I accidently failed to assign the
return code to rc before returning.

Brian Behlendorf d134105bba Linux 2.6.34 compat: add_range() symbol collision
The prototype for an add_range() function was added to the kernel
header include/linux/range.h which conflicts with the static
add_range() defined in zfs_fm.c.  To resolve the conflict all
range functions in zfs_fm.c have been prefixed with zei which
is short for the zfs_ecksum_info struct since all of these
functions operate on that base structure.

Brian Behlendorf 9820fd89a4 Explicitly cast sizeof() to avoid format warnings
Simply explicity cast sizeof() to a 'long int' these numbers will
always be small and the removes all ambiguity.

Brian Behlendorf 45cb33f64f Ensure devices are always created/removed
Devices were only being created at module load time or when a
dataset was created.  Similiar devices were not always being
removed at all the correct times.  This patch updates all the
places where devices should either be created or removed.  I'm
reasonably sure I got them all but if theres a case I missed
we can catch it with a follow up patch.

        module load/unload
        zfs create/remove
        zpool import/export
        zpool destroy

This patch also adds a simple regression test to zconfig.sh
to ensure zpool import/export is basically working properly.
This test specifically checks that devices are created
properly, removed after export, created after import, and
removed as a consequence of a zpool destroy.

Brian Behlendorf 122e5b44e1 Add missing mutex_exit(&zvol_state_lock)
With the recent ZVOL update zvol_set_volblocksize() accidentally
lost its mutex_exit().  This was noticed when zvol_create_minor()
blocked on the zvol_state_lock while it was holding the
spa_namespace_lock().  This caused everything to get blocked
up and hung the system.

Brian Behlendorf 34229a2f2a Reduce stack usage for recursive traverse_visitbp()
Due to  limited stack space recursive functions are frowned upon in
the Linux kernel.  However, they often are the most elegant solution
to a problem.  The following code preserves the recursive function
traverse_visitbp() but moves the local variables AND function
arguments to the heap to minimize the stack frame size.  Enough
space is initially allocated on the stack for 20 levels of recursion.
This change does ugly-up-the-code but it reduces the worst case
usage from roughly 4160 bytes to 960 bytes on x86_64 archs.
