Brian Behlendorf 46b2d46053 Merge branch 'fix-stack-traverse_visitbp' into refs/top-bases/fix-branch 2010-06-29 11:04:51 -07:00
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.

These changes are now taken care of by the fix-stack-traverse_impl
topic branch which not only solves the uninit problem but also
moves these locals off the stack and on to the heap.

Brian Behlendorf f32ec2346b Linux bcopy() requires word aligned memory, use memcpy()
Much to my surprise bcopy() under Linux appears to copy the data in
word sized chunks.  It does the right thing but if you buffer is not
a multiple of the word size you will be reading past the end of your
buffer.  Or at least that is what valgrind is reporting.  We should
be using mempcy() anyway on Linux so replace bcopy() with memcpy()
to resolve the issue.

Brian Behlendorf 52bb0d8e75 Ensure zio_bad_cksum_t is initialized
This may not strictly be needed but it does keep gcc happy.  We
should keep our eye on this though if the extra bcopy significantly
impacts performance.  It may.

Brian Behlendorf 5b1f2041e5 Silence 3 additional large kmem warnings
The following are 3 cases where move than 2 pages are allocated
with a kmem_alloc()... but not a lot more.  For now we just disable
the warning with KM_NODEBUG and this can be revisted latter to
see if it's worth shrinking the allocation or perhaps moving it
to a slab.

Brian Behlendorf d6ea5e8cef Additional ZVOL cleanup in zvol_set_volsize()
The following cleanup was missed in the first pass when the ZVOL
implementation was updated.  An extra instance of a zvol_state_t
was removed from the stack and the error handling was simplified.

Brian Behlendorf 6914386b85 Never sleep under taskq_dispatch()
There are cases where under Linux it is not safe to sleep in
taskq_dispatch().  Rather than adding Linux specific code to
detect these cases I opted to keep it simple and just never
allow a sleep here.  The impact of this should be minimal.

Brian Behlendorf 0c11631b02 Fix for fix-stack-dmu_objset_snapshot should be 'sn' not '&sn'
I missed a instanse of removing the & operator when reducing the
stack usage in this function.  This unfortunately doesn't cause
a compile warning but it is does cause ztest failures.  Anyway,
update the topic branch to correct this mistake.

Certain function must never be automatically inlined by gcc because
they are stack heavy or called recursively.  This patch flags all
such functions I have found as 'noinline' to prevent gcc from making
the optimization.

Brian Behlendorf 869764f64d Add fix-stack-dsl_deleg_get topic branch
Reduce stack usage in dsl_deleg_get, gcc flagged it as consuming a
whopping 1040 bytes or potentially 1/4 of a 4K stack.  This patch
moves all the large structures and buffer off the stack and on to
the heap.  This includes 2 zap_cursor_t structs each 52 bytes in
size, 2 zap_attribute_t structs each 280 bytes in size, and 1
256 byte char array.  The total saves on the stack is 880 bytes
after you account for the 5 new pointers added.

Also the source buffer length has been increased from MAXNAMELEN
to MAXNAMELEN+strlen(MOS_DIR_NAME)+1 as described by the comment in
dsl_dir_name().  A buffer overrun may have been possible with the
slightly smaller buffer.

Brian Behlendorf 14d073e298 Add linux-sha2 topic branch for portability
The upstream ZFS code has correctly moved to a faster native sha2
implementation.  Unfortunately, under Linux that's going to be a little
problematic so we revert the code to the more portable version contained
in earlier ZFS releases.  Using the native sha2 implementation in Linux
is possible but the API is slightly different in kernel version user
space depending on which libraries are used.  Ideally, we need a fast
implementation of SHA256 which builds as part of ZFS this shouldn't be
that hard to do but it will take some effort.

Brian Behlendorf b8cc785fb6 Add fix-stack-lzjb topic branch
Reduce kernel stack usage by lzjb_compress() by moving uint16 array
off the stack and on to the heap.  The exact performance implications
of this I have not measured but we absolutely need to keep stack
usage to a minimum.  If/when this becomes and issue we optimize.

Brian Behlendorf f3a61f709d Add fix-metaslab topic branch
If your only going to allow one allocator to be used and it is defined
at compile time there is no point including the others in the build.
This patch could/should be refined for Linux to make the metaslab
configurable at run time.  That might be a bit tricky however since
you would need to quiese all IO.  Short of that making it configurable
as a module load option would be a reasonable compromise.

In the linux kernel 'current' is defined to mean the current process
and can never be used as a local variable in a function.  Simply
replace all usage of 'current' with 'curr' in this function.

Brian Behlendorf 67e8f48f1b Update linux-kernel-device to handle ioc changes
Upstream they modified the ioctl code so we need to make similiar
updates since we modify the API ourselves to always pass a pointer

state which is used by the zevent code.

Brian Behlendorf 800b7a03e1 Update linux-kernel-disk ZVOL implementation
The ZVOL interfaces changed significantly with the latest update.  I've
updated the Linux version of the code to handle this and it looks like
the net result has been a simpler implementation which is good!  Plus,
I'm relatively sure the ZIL integration is right this time although it
needs some serious crash testing to verify that.

Also minor additions to vdev_disk for .hold and .rele callbacks.
Currently, they do nothing and I may be able to simply stub them out
with NULLs for Linux since opening the device in Linux should have
much the same effort.  More investigation is needed though since
the ZFS interface may make some demands here I'm overlooking.

Brian Behlendorf 21690470e3 Update linux-zpios to use updated DMU API
The DMU API has been modified to remove the dmu_objset_open, and
dmu_objset_close functions.  Now you must explicitly *_create an
objset, then *_own it, *_disown it when not in use, and *_destroy
it when your through.  All and all I like the API much better.

Additionally, while I was here I moved the zpios_cmd_t off the
stack because previous analysis showed it was very stack heavy.
