Problem description:
--------------------The problem reported by one of the customer was when a logical array
is deleted(from the SDK, from the GUI, from arcconf) then the
corresponding physical device (/dev/sdb, for example) is not removed
from the Linux namespace. So you end up with a "dead" device
entry. And some of the linux tools go slightly wonky.Solution:
---------Based on the notification from FW, the driver calls
"scsi_remove_device" for the DELETED drive. This call not only informs
the scsi device status to the SCSI mid layer and also it will remove
corresponding scsi device entries from the Linux sysfs.Signed-off-by: Mahesh Rajashekhara

Problem description:
--------------------The issue reported by one of the customer was able to read LBA beyond
the array reported size with "sg_read" utility. If N is the last block
address reported, then should not be able to read past N,
i.e. N+1. But in their case, reported last LBA=143134719. So should
not have been able to read with LBA=143134720, but it is read without
failure, which means reported size to the OS is not correct and is
less than the actual last block address.Solution:
---------Firmware layer exposes lesser container capacity than the actual
one. It exposes [Actual size - Spitfire space(10MB)] to the OS, IO's
to the 10MB should be prohibited from the Linux driver. Driver checks
LBA boundary, if its greater than the array reported size then sets
sensekey to HARDWARE_ERROR and sends the notification to the MID
layer.Signed-off-by: Mahesh Rajashekhara

The default driver setting is "expose_physicals=0", which means raw
physical drives are not exposed to OS. If the user wants to expose
connected physical drives, enable "expose_physicals" module parameter.
With the new JBOD firmware, physical drives are not available for
"expose_physicals>0". In function "aac_expose_phy_device", modified
to reset the appropriate bit in the first byte of inquiry data. This
fix exposes the connected physical drives.Signed-off-by: Mahesh Rajashekhara

…it slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files. percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.Signed-off-by: Tejun Heo <tj@kernel.org>

These particular problems were reported by Cisco and SAP and customers
as well. Cisco reported on RHEL4 U6 and SAP reported on SLES9 SP4 and
SLES10 SP2. We added these fixes on RHEL4 U6 and gave a private build
to IBM and Cisco. Cisco and IBM tested it for more than 15 days and
they reported that they did not see the issue so far. Before the fix,
Cisco used to see the issue within 5 days. We generated a patch for
SLES9 SP4 and SLES10 SP2 and submitted to Novell. Novell applied the
patch and gave a test build to SAP. SAP tested and reported that the
build is working properly.We also tested in our lab using the tools "dishogsync", which is IO
stress tool and the tool was provided by Cisco.Issue1: File System going into read-only mode
Root cause: The driver tends to not free the memory (FIB) when the
management request exits prematurely. The accumulation of such
un-freed memory causes the driver to fail to allocate anymore memory
(FIB) and hence return 0x70000 value to the upper layer, which puts
the file system into read only mode.Fix details: The fix makes sure to free the memory (FIB) even if the
request exits prematurely hence ensuring the driver wouldn't run out
of memory (FIBs).Issue2: False Raid Alert occurs
When the Physical Drives and Logical drives are reported as deleted or
added, even though there is no change done on the systemRoot cause: Driver IOCTLs is signaled with EINTR while waiting on
response from the lower layers. Returning "EINTR" will never initiate
internal retry.Fix details: The issue was fixed by replacing "EINTR" with
"ERESTARTSYS" for mid-layer retries.Signed-off-by: Penchala Narasimha Reddy

This patch modifies scsi_host_template->change_queue_depth so that
it takes an argument indicating why it is being called. This will be
used so that if a LLD needs to do some extra processing when
handling queue fulls or later ramp ups, it can do so.This is a simple port of the drivers setting a change_queue_depth
callback. In the patch I just have these LLDs adjust the queue depth
if the user was requesting it.Signed-off-by: Mike Christie

Also converted pmcraid_change_queue_depth and then verified
all modules compile using "make allmodconfig" for any new build
warnings on X86_64.Updated original description after combing two original

Right now SCSI and others do their own command timeout handling.
Move those bits to the block layer.Instead of having a timer per command, we try to be a bit more clever
and simply have one per-queue. This avoids the overhead of having to
tear down and setup a timer for each command, so it will result in a lot
less timer fiddling.Signed-off-by: Mike Anderson

Seen:
kernel BUG at arch/i386/lib/usercopy.c:872
under a 2.6.18-8.el5 kernel. Traced it to a garbage-in/garbage-out
ioctl condition in the aacraid driver.Adaptec's special ioctl scb passthrough needs to check the validity of
the individual scatter gather count fields to the maximum the adapter
supports. Doing so will have the side effect of preventing
copy_from_user() from bugging out while populating the dma buffers.
This is a hardening effort, issue was triggered by an errant version
of the management tools and thus the BUG should not be seen in the
field.[jejb: fixed up compile failure]
