Since sectors is not modified, it's more straightforward to do this.

Previously, some control CDBs did not allocate memory in pages for their
data buffer, but just did a kmalloc. This patch makes all cdbs allocate
pages.
This has the benefit of streamlining some paths that had to behave
differently when we used two allocation methods. The downside is that
all accesses to the data buffer need to kmap it before use, and need to
handle data in page-sized chunks if more than a page is needed for a given
command's data buffer.

Before transport_allocate_resources used to be a no-op for
SCF_SCSI_NON_DATA_CDB cdbs, which got lots with your patch. Given that
they should have a zero length your patch should be fine, but such
subtilities would be nice to be documented in the changelog.

I would have preferred to switch to goto based unwinding from the start.
But it's not a major issue, so if no one else complains I'm fine with it
beeing fixed up in a later patch.

Any reason these are exported?

You should be able to kill SCF_PASSTHROUGH_CONTIG_TO_SG as well.

target_core_pscsi.c is a module, and uses it.

I'm just going to add a test to the conditional to only call get_mem if
cmd->data_length is nonzero, seems better.

Due to all cdbs' data buffers being referenced by scatterlists, buffers
of more than a page are not contiguous. Instead of handling this in all
control command handlers, we may be able to get away with just limiting
control cdb data buffers to one page. The only control CDBs we handle that
have potentially large data buffers are REPORT LUNS and UNMAP, so if we
didn't want to live with this limitation, they would need to be modified
to walk the pages in the data buffer's sgl.

Normal Linux style would be the operand at the end of the previous line.

Instead of converting rd_dr to be se_mem-free, just remove it.
This also lets us remove hooks like do_se_mem_map, that are in the common
path but only implemented by rd_dr.

From: Andy Grover @ 2011-07-07 22:33 UTC (permalink / raw)
To: target-devel; +Cc: linux-scsi
Both backstores and fabrics use arrays of struct scatterlist to describe
data buffers. However TCM used struct se_mems, basically a linked list
of scatterlist entries. We are able to simplify the code by eliminating
this intermediate data structure and just using struct scatterlist[]
throughout.

Probably not worth it for this series, but for a next one, but what
about killing transport_generic_map_mem_to_cmd? The drivers can do the
assignment just as fine, and we could probably set
SCF_SCSI_CONTROL_NONSG_IO_CDB automatically when the fabric sets the S/G
list before calling in for processing.
Or maybe we should stop calling transport_generic_get_mem from the
core entirely and just export it as a helper to the fabrics as the
default implementation. This actually sounds like the nicest option
to me.

How is moving the task <-> cmd linkage related to the rest of the patch?
It probably should be a separate preparatory patch, but at least needs
some good documentation.

This still looks incorrect to me as control CDBs might have to
end up in ->cdb_none. Or did I miss how this gets handled now?

There's no clean (easy) way for me to extract this from the rest of the
patch, so I'm just going to add some text to the changelog.
BTW I've cleaned up alloc_task some more in a follow-on patch, will post
shortly.

True, but they're not unusual, so I left instances like this.

See patch 16, it fixes this.

From: Andy Grover @ 2011-07-07 22:33 UTC (permalink / raw)
To: target-devel; +Cc: linux-scsi
pr_debug and dynamic debug can give us the flexibility to choose
debugprints in a more standard way than these macros.
Since these debug statements were seldom enabled, there was some bitrot
in their parameters, so those are also corrected.
Use pr_err etc. macros instead of printk(KERN_ERR..).

To: target-devel; +Cc: linux-scsi

debug infrastructure.
Use pr_err etc. instead of printk(KERN_ERR...).

To: target-devel; +Cc: linux-scsi
This should have the effect of quieting dmesg output when there are no
issues, and yet still allow these messages to be enabled during a debugging
session if needs be.
Replaced all printk(KERN_ERR) with pr_err()
Replaced all printk(KERN_INFO) with pr_debug()
Replaced all uses of TRACE() with pr_debug()
Moved PRINT_BUFF macro to iscsi_target_util.c, only place it's used
Remove iscsi debug config option

According to sbc3r27, WRITE SAME with sectors=0 either writes to the
end of the lun, or returns an error, depending on if WSNZ was set to 0 or
1 in the block limits VPD (0xB0). This patch sets that bit, and
returns the error. Previously we used the block size, I don't know why,
but it seems wrong.

kunmap in each error handler, but goto error handling at the end, and
kunmap there. Based on code review from hch.

of tasks they allocated, or -errno. Make this a little cleaner, and
fix a bug where -errno would not be caught in transport_new_cmd_obj().
Suggested by hch.

No functional changes. Remove extraneous parentheses in if statements,
where there is no chance of order-of-operations confusion. Most
significantly, all instances of parens around bit-testing are retained.

I came across these in the paren purge, but wanted to break them out in
a separate patchset so they didn't get lost in the sea of boringness that
those csets embody.
The first bit decrements np->np_exports outside the conditional, and
removes the double-negativity, for clarity.
The second bit removes the test for &cmd->se_cmd entirely, since if cmd
is valid, there's no way the test will ever fail.

Hey Andy,
Thanks alot for this cleanup and simplfication effort, and apologies for
the delay on this while catching up the last weeks.. I ended up merging
this series, and ran into a number of issues that should (hopefully) now
be resolved with some additional bugfixes.
Following up inline on the specifics..

Since sectors is not modified, it's more straightforward to do this.

From: Andy Grover @ 2011-07-09 1:18 UTC (permalink / raw)
To: target-devel; +Cc: linux-scsi
Previously, some control CDBs did not allocate memory in pages for their
data buffer, but just did a kmalloc. This patch makes all cdbs allocate
pages.
This has the benefit of streamlining some paths that had to behave
differently when we used two allocation methods. The downside is that
all accesses to the data buffer need to kmap it before use, and need to
handle data in page-sized chunks if more than a page is needed for a given
command's data buffer.
Finally, note that cdbs with no data buffers are handled a little
differently. Before, SCSI_NON_DATA_CDBs would not call get_mem at all
(they'd be in the final else in transport_allocate_resources) but now
these will make it into generic_get_mem, but just not allocate any
buffers.

So this bit was triggering memory corruption with TCM_Loop because the
SCSI ML is using contigious buffers for certain control CDBs in
drivers/scsi/scsi_scan.c and elsewhere:
The follow patch has been committed (post se_mem removal) to honor
sg->offset to make TCM_Loop function as expected:
commit f6e0c5a75a8056def88c4934e055d28499b073d2
Author: Nicholas Bellinger <nab@linux-iscsi.org>
Date: Sat Jul 16 22:44:58 2011 -0700
target: Make transport_kmap_first_data_page honor sg->offset
This patch makes transport_kmap_first_data_page() honor sg->offset, as
fabrics like tcm_loop need to handle this case for control CDBs generated
by the SCSI midlayer that are based on a contigious buffer.
This fixes memory corruption with tcm_loop introduced with commit:
commit 0b5660d2eebadc5853cf268d6136aeecbd251d6a

of more than a page are not contiguous. Instead of handling this in all
control command handlers, we may be able to get away with just limiting
control cdb data buffers to one page. The only control CDBs we handle that
have potentially large data buffers are REPORT LUNS and UNMAP, so if we
didn't want to live with this limitation, they would need to be modified
to walk the pages in the data buffer's sgl.

Instead of converting rd_dr to be se_mem-free, just remove it.
This also lets us remove hooks like do_se_mem_map, that are in the common
path but only implemented by rd_dr.

To: target-devel; +Cc: linux-scsi
Both backstores and fabrics use arrays of struct scatterlist to describe
data buffers. However TCM used struct se_mems, basically a linked list
of scatterlist entries. We are able to simplify the code by eliminating
this intermediate data structure and just using struct scatterlist[]
throughout.
Also, moved attachment of task to cmd out of transport_generic_get_task
and into allocate_control_task and allocate_data_tasks. The reasoning
is that it's nonintuitive that get_task should automatically add it to
the cmd's task list -- it should just return an allocated, initialized
task. That's all it should do, based on the function's name, so either the
function shouldn't do it, or the name should change to encapsulate the
entire essence of what it does.

Although this patch did not directly remove the memsets for newly
allocated pages used with transport_generic_map_mem_to_cmd(), the issue
as below of reproducable strangeness with control CDB payloads without
the explict memset of allocated pages. As much as I would have liked to
leave the memset out, I don't think it's safe to do. Added the
following:

target/iscsi: Make iscsit_alloc_buffs explict memset allocated pages
This patch makes iscsit_alloc_buffs() explictly memset allocated pages in
order to address some control CDB payload strangeness with iscsi-target
during recent testing. Be paranoid here and always zero the complete
payload just to be sure.
This patch also fixes the failure path to properly release and clear
cmd->t_mem_sg.

Ditto here. Not clearing the newly allocated pages payload here and has
been resulting in some strange issues with unexpected payloads for
control CDB emulation with iscsit_alloc_buffs(). Readding the explict
memset here, and re-added the missing 'out' label handling with the
following:

target: Make transport_generic_get_mem() explictly memset allocated pages
This patch makes transport_generic_get_mem() explictly memset allocated pages in
order to address some control CDB payload strangeness during recent testing.
Be paranoid here and always zero the complete payload just to be sure.
This reverts part of the following commit that removed the memset of
data payloads:

Author: Andy Grover <agrover@redhat.com>

target: Don't pass dma_size to generic_get_mem. Don't memset.
This also fixes the failure path that was also dropped in commit:

The extra atomic_inc for cmd->t_fe_count and cmd->t_se_count here is
bogus, and was causing all control CDBs to be leaked.. Committed the
following bugfix:
commit 53dcfc1555875d3c2000c3df71ea74e91f57cb6c
Author: Nicholas Bellinger <nab@linux-iscsi.org>
Date: Sat Jul 16 23:38:58 2011 -0700
target: Fix control se_cmd descriptor memory leak
This patch removes a bogus duplicate increment of cmd->t_fe_count and
cmd->t_se_count in the new transport_allocate_control_task() logic.
As these two values are incremented once for all CDB types in
transport_new_cmd_obj(), the duplicate increment was causing all
control se_cmd descriptors to be leaked in transport_generic_remove()
when transport_dec_and_check() was returning non zero.
This bug was introduced with commit:
commit 84b6dd77a6035dff105f628589b8aac8a227031e

Calling dev->transport->map_task_SG() here for all cases is incorrect,
and was triggering an OOPs during iscsi-target initial LUN scan.. Fixed

Hi nab, obviously if it's breaking things the memsets need to go back
for now, but surely it's a sign that somewhere there's a bug. You only
see corruption with control CDBs you say? Any more info on the
strangeness you're seeing?

The immediate case that I ran into with the very latest iscsi-target
code was bogus output with 'sg_inq -i' (INQUIRY EVPD=0x83) in the
'Designation descriptor number 5' field.

This should use clear_highpage, or even better just the __GFP_ZERO flag

Indeed. But why did you also commit
"target/iblock: Make iblock_map_task_SG only for SCF_SCSI_DATA_SG_IO_CDB"
which is a hacky workaround for the same issue inside iblock?

What is that comment supposed to help with? It's rather confusing to
be honest.

Not exactly.. There where two seperate issues with Andy's original
patch:
The incorrect calling of ->map_task_SG() for all types of se_cmd
desciptors (eg: SCF_SCSI_NON_DATA_CDB), and the case for IBLOCK
providing ->map_task_SG(), but not actually needing to allocate bios
for SCF_SCSI_CONTROL_SG_IO_CDB type traffic.
But fair point here, as this would be better served by adding
->map_control_SG and ->map_data_SG instead of a single ->map_task_SG()
for both cases. Making this change now and will send out shortly..

pr_debug and dynamic debug can give us the flexibility to choose
debugprints in a more standard way than these macros.
Since these debug statements were seldom enabled, there was some bitrot
in their parameters, so those are also corrected.
Use pr_err etc. macros instead of printk(KERN_ERR..).

To: target-devel; +Cc: linux-scsi

debug infrastructure.
Use pr_err etc. instead of printk(KERN_ERR...).

Great stuff, however with the amount of I/O path code that was removed
in:
commit 0b5660d2eebadc5853cf268d6136aeecbd251d6a
Author: Andy Grover <agrover@redhat.com>
Date: Fri Jul 8 17:25:13 2011 -0700
target: Make all control CDBs scatter-gather
and:
commit 84b6dd77a6035dff105f628589b8aac8a227031e
Author: Andy Grover <agrover@redhat.com>
Date: Fri Jul 8 15:22:14 2011 -0700
target: Eliminate usage of struct se_mem
really made things difficult to debug the bigger issue with this
series..
So that said, some new pr_debug() messages for the I/O path would be
really helpful.. ;)

This should have the effect of quieting dmesg output when there are no
issues, and yet still allow these messages to be enabled during a debugging
session if needs be.
Replaced all printk(KERN_ERR) with pr_err()
Replaced all printk(KERN_INFO) with pr_debug()
Replaced all uses of TRACE() with pr_debug()
Moved PRINT_BUFF macro to iscsi_target_util.c, only place it's used
Remove iscsi debug config option

According to sbc3r27, WRITE SAME with sectors=0 either writes to the
end of the lun, or returns an error, depending on if WSNZ was set to 0 or
1 in the block limits VPD (0xB0). This patch sets that bit, and
returns the error. Previously we used the block size, I don't know why,
but it seems wrong.

allocate_control_task and allocate_data_tasks each return the number
of tasks they allocated, or -errno. Make this a little cleaner, and
fix a bug where -errno would not be caught in transport_new_cmd_obj().

To: target-devel; +Cc: linux-scsi
No functional changes. Remove extraneous parentheses in if statements,
where there is no chance of order-of-operations confusion. Most
significantly, all instances of parens around bit-testing are retained.

I came across these in the paren purge, but wanted to break them out in
a separate patchset so they didn't get lost in the sea of boringness that
those csets embody.
The first bit decrements np->np_exports outside the conditional, and
removes the double-negativity, for clarity.
The second bit removes the test for &cmd->se_cmd entirely, since if cmd
is valid, there's no way the test will ever fail.

The transports really don't need the entire struct se_cmd to allocate
the memory for the se_task. If it wasn't for pscsi, they wouldn't even
need the *cdb.
Modify pscsi to allocate space for cdb at the end of pscsi_plugin_task,
instead of a separate allocation.

Nice one! Note that except for pscsi we really don't need se_tasks
to start with. I'm not sure how easy it is to move the whole task
logic into it, but just allowing the other transports to allocate a
single se_task + se_cmd + private data in one go should avoid one
more memory allocation.

We can assume each se_cmd only needs 1 se_task???
I couldn't see where the max sectors per se_cmd was limited, therefore
we needed to support cmds being broken up into
se_sub_dev.max_sectors-size chunks, and therefore being >1 se_task per
se_cmd, for all backstores not just pscsi?

The most important backend, iblock already handles arbitrarily sized
payloads by using multiple bios internally, which is much lower overhead
than using the multiple task complexity, and the ramdisk code has no
inherent limitation either. The file code has a limitation on the
number of iovecs accepted by the kernel, and only the pscsi backend
really needs multiple "tasks".
Given that the performance of iblock is the important one streamline
the path for this backend as much as possible sounds like a good idea.
