linux-next: build failure after merge of the scsi tree

linux-next: build failure after merge of the scsi tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 680 bytes --]

Hi James,

After merging the scsi tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

drivers/ata/sata_svw.c: In function 'k2_sata_proc_open':
drivers/ata/sata_svw.c:327:2: error: implicit declaration of function 'PDE' [-Werror=implicit-function-declaration]
drivers/ata/sata_svw.c:327:56: error: invalid type argument of '->' (have 'int')
drivers/ata/sata_svw.c:328:1: warning: control reaches end of non-void function [-Wreturn-type]

Caused by commit 343ac4b031a7 ("[SCSI] sata_svw: convert to scsi proc_ops").

I have used the scsi tree from next-20120322 for today.

Additionally, I am the author and maintainer of that driver and I don't
remember ever being CCed on that patch ... or did I miss it ?

Cheers,
Ben.

You missed it ... I added you and Jeff for automatic cc's when the
commit hit the scsi tree.

This is the mail log:

That's defined in linux/proc_fs.h

What was the config?  Was it a no-PROCFS config, or is this just
something that needs to be explicitly included?

Allright, Mar 22, that's yesterday (.au time)... that's a short time
between notifying the maintainer and going into -next :-) No biggie,
I'll have a look next week, it's just annoying to get build failure
reports from Stephen about drivers I own for patches I never heard
about ...

Cheers,
Ben.

Yes, sorry ... it's one of those large all or nothing type series that
touches about 33 different drivers (about 75% of which are
unmaintained).

I would have checked the ppc compile if I still had a working ppc
machine.  Having looked through the code, I think this is the fix ...
could someone check?

See above, that was a powerpc ppc64_defconfig.  It certainly has PROCFS
enabled.  Almost everything needs to be explicitly included - see Rule 1
in Documentation/SubmitChecklist ...

Implicit includes are vulnerable to CONFIG changes and
architecture/platform differences in the include files.  I have seen lots
of these.  :-(

Your email was not mentioned in changelogs for 6 years nor the driver
has specific MAINTAINERS entry.

To be more specific, it was a patch series that was never CC'd to ANY 
driver author, nor linux-ide, nor LKML.

linux-next: build failure after merge of the scsi tree

[Stephen Rothwell]

Hi James,

After merging the scsi tree, today's linux-next build (sparc defconfig)
failed like this:

drivers/scsi/qlogicpti.c:1285:27: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
  .eh_host_reset_handler = qlogicpti_reset,
                           ^

Caused by commit

  af167bc42d86 ("scsi: qlogicpti: move bus reset to host reset")

I have reverted that commit for today.

Thanks Stephen, I'll prepare a merged tree as well for Linus, so we
don't lose this when the block tree is merged for 4.11.

linux-next: build failure after merge of the scsi tree

Hi all,

After merging the scsi tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

Well, the driver was reviewed, but I don't think biting the heads of
the reviewers would help.

So this is the problem: I don't think this was actually communicated
this in a meaningful way; I think that's because we don't really have a
functional process for deprecating stuff.  Saying "this is broken or
deprecated" doesn't work because people don't necessarily see it and
even if they do, they often forget.  Putting it in some document
doesn't work either because we can't agree which one (and even if we
could, I bet the reviewers won't always consult it).

So here's the thing: if you want me to notice that a driver is using a
deprecated API, the API must be *marked* as deprecated so that I get a
build warning to investigate.  Absent that, I'm going to assume the
reviewers knew what they were talking about ... and likely a build
warning is the only way they'd know as well.

Well, I'm sorry, but it's a timing thing.  I could have removed this
driver from the pull it if I'd got the next failure before it was in
-flight.  I did incubate this final pull tree in next for a week which
was supposed to catch all the issues like this.

Sure, because SSCI people merge broken crap and I can wipe up the mess they
create.

Dammit, SCSI folks knew for a long time that the old interface goes away,
but just waving crap through and let other people deal with the outcome is
way simpler.

And of course that hotplug code in this new driver is broken as hell. It
leaks notifiers in cases of errors and is racy against cpu hotplug. The
proper thing would be to mark this trainwreck broken and be done with it.

I'm seriously pissed off as I now have to rebase my stuff and cleanup that
sad affair in order to not break bisects completely.

Yours grumpy,

Well, there probably won't be any linux-next releases until Jan 3, so that's ok.

Yeah, we'll handle it - that's why the final chunk of changes were left to after 
-rc1, to not cause such merge conflicts upstream.

For now I've excluded the relevant -tip side commits from the linux-next branch.

Well, that's a bit of a problem given that the SCSI tree has a pending
pull request including this driver.

Thomas, can you do another fixup in your tip tree like you did for the
two BNX2* drivers?

linux-next: build failure after merge of the scsi tree

Hi James,

After merging the scsi tree, today's linux-next build (x86_64
allmodconfig) failed like this:

linux-next: build failure after merge of the scsi tree

[Stephen Rothwell]

Hi James,

After merging the scsi tree, today's linux-next build (powerpc
allyesconfig) failed like this:

In file included from drivers/scsi/mpt3sas/mpt3sas_scsih.c:59:0:

Hm, yes, the commit causes a dependency on blkdev.h but doesn't pull it
in.  I'll drop it for a resubmit.

Hi James,

After merging the scsi tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/usb/gadget/function/f_mass_storage.c:280:12: error: 'MAX_COMMAND_SIZE' undeclared here (not in a function)
  u8   cmnd[MAX_COMMAND_SIZE];
            ^

Caused by commit 0e640c799103 ("Replace MAX_COMMAND_SIZE with BLK_MAX_CDB").

I have used the scsi tree from next-20150601 for today.

Hannes posted a more correct fix for it today to the scsi list.
However, sorting this out isn't just about the short term fix:  We can't
afford the bisection failure of SCSI not building over a wide range of
commits, so our tree will need to be pulled ahead of the driver-core
tree.

I've got to say, while it's great that linux-next spotted this ahead of
time (saves us all a massive beating from Linus, thanks Stephen) it's
unfortunate to have this type of thing turn up on the edge of a merge
window, especially caused by a trivial commit which perhaps shouldn't
have gone in so late.

Thanks and just so.

It seems that nothing uses either return value,
so it's probably better to use void for both
sdev_prefix_printk and scmd_printk.

I added the following merge resolution patch.  Someone will have to
remember to tell Linus.  Also, the void return may be able to be
propagated further up the chain since these two new affected functions
now always return 0.

Not yet.  Those are for the buildbolt to find any issues before pushing

And I pulled it from drivers-for-3.18 early on Thursday, but that didn't

linux-next: build failure after merge of the scsi tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 1015 bytes --]

Hi James,

After merging the scsi tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

In file included from include/linux/sched.h:17:0,
                 from include/linux/blkdev.h:4,
                 from drivers/scsi/constants.c:10:
drivers/scsi/constants.c: In function 'scsi_opcode_sa_name':
include/linux/kernel.h:54:32: error: invalid application of 'sizeof' to incomplete type 'const char *[]'
 #define ARRAY_SIZE(arr) (sizeof(arr) / sizeof((arr)[0]) + __must_be_array(arr))
                                ^
drivers/scsi/constants.c:300:15: note: in expansion of macro 'ARRAY_SIZE'
  if (opcode < ARRAY_SIZE(cdb_byte0_names))
               ^

Caused by 94bafab0008c ("scsi: consolidate opcode lookup in
scsi_opcode_sa_name()").  This build does not have
CONFIG_SCSI_CONSTANTS set.

I have used the scsi tree from next-20141031 again (since yesterday's
tree had a different build problem).

Thanks, I've folded that patch into the one that caused the issue.

linux-next: build failure after merge of the scsi tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 700 bytes --]

Hi James,

After merging the scsi tree, today's linux-next build (powerpc ppc64_defconfig)
failed like this:

drivers/scsi/scsi_lib.c: In function 'scsi_io_completion':
drivers/scsi/scsi_lib.c:1048:5: error: implicit declaration of function 'SCSI_LOG_LEVEL' [-Werror=implicit-function-declaration]
     level = SCSI_LOG_LEVEL(SCSI_LOG_MLCOMPLETE_SHIFT,
     ^

Caused by commit b6568e80be82 ("scsi: simplify
scsi_log_(send|completion)").  SCSI_LOG_LEVEL is defined in
drivers/scsi/scsi_logging.h, but only if CONFIG_SCSI_LOGGING is defined.

I have used the version of the scsi tree from next-20141031 for today.

Hi James,

Anything preventing this patch set from getting picked up? Do you need a resend?

I'll wait for the next couple of build cycles before pushing (assuming

Hi James, I just re-sent all patches which are against
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git.
This kernel already have Greg's "Drivers: scsi: remove _dev*  
attributes" patch.

Let me know if you have any questions for these patches.

Thanks for for your help!

Drop everything and resend still, I think.  There's still a rebase
problem, because the merge failure will happen if I rebase the misc tree
to beyond Greg's merge point and I'd rather not have to worry about it.

We can do this either way.

This change should be pushed to Linus in time for 3.8-final, so there
should not be any bisect issues.

Not exactly.  The patch which makes them nops went into 3.8.  Now
there's a patch queued in, Gregs tree I presume, to remove them all and
the #defines which causes the compile failure.

If it's a simple gcc bug, just ignore it.

I do need you to redo the patches to remove the __dev annotations,
though.  We can't risk introducing a bisect killing compile breakage if
Greg's tree merges before mine in the next merge window.

Re: linux-next: build failure after merge of the scsi tree

[Brian King]

It looks like this was a due to the fact that the new patches
added __devinit tags in the same merge window the __devinit tag
itself was getting removed.

As to the sparse warnings, this patch fixed the ones that
were actual bugs in the new code, although we could have
made that more clear in the patch description.

http://marc.info/?l=linux-scsi&m=135716576204083&w=2

There is one outstanding issue I am aware of which was an
array bounds compiler warning which looks to be a misdetection
by the compiler. Wendy and I discussed adding a BUG_ON
to stop the compiler from complaining.

Wendy - lets queue these two changes up ASAP. They should both
be very simple changes.

Thanks,

Brian

OK, fine, I'll drop all the ipr patches.  I've been waiting for a month
for them to fix the smatch and sparse warnings.  Please resend the

linux-next: build failure after merge of the scsi tree

Hi James,

After merging the scsi tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

drivers/scsi/ipr.c:9138:22: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'ipr_enable_msix'
drivers/scsi/ipr.c:9165:22: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'ipr_enable_msi'

Caused by commit 7af0de314b73 ("[SCSI] ipr: Add support for MSI-X and
distributed completion") interacting with commit 54b956b90360 ("Remove
__dev* markings from init.h") from the drover-core.current tree.

I have added the following merge fix patch for today which could be added
directly to the scsi tree (please).

That probably just about works, since 758da9dc2be8 is just removing
redundant code.

I've got this all fixed up properly in for-next now.

linux-next: build failure after merge of the scsi tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 595 bytes --]

Hi James,

After merging the scsi tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

drivers/base/dd.c:27:28: fatal error: scsi/scsi_scan.h: No such file or directory

Caused by commit eea03c20ae38 ("Make wait_for_device_probe() also do
scsi_complete_async_scans()") from Linus' tree interacting with commit
758da9dc2be8 ("[SCSI] cleanup usages of scsi_complete_async_scans") from
the scsi tree.

I have reverted commit 758da9dc2be8 for today (which may not be the best
thing to do).

No you are not at all.  That's not the function to grep for, I have no
idea what you are trying to prove with this grep, but it is flat out
wrong.

Thanks to Gerard, I've looked at your patches, and it's obvious that you
didn't look to see what would needed to be done to convert the
drivers/staging/ drivers to your new interface.

In short, it's trivial, and it looks like you could take one of your
existing patches, rename the file, and it would apply cleanly to two of
the drivers, so you are already 2/3 done.

The other one is even simpler than that, I've included it below for your
perusal.

If you need me to, I can write these patches, but I can't build or test
them, as I do not see the proc_ops field in the scsi_host_template in
Linus's tree.

It's just part of changing apis, if you want to break them, then fix up
the existing users.  If you need help with existing users, just ask.

So feel free to take my patch below for your patch series, and if you
want me to fix up the other two, just ask.

thanks,

greg k-h

Sorry, poorly worded on my part. What I meant to say was I could see
the commits in the repository when doing

The plan is to put them back once we go 3.4-rc1 so we have a whole
release cycle to fix up any breakage.

Only the comedi one should probably stick around, and even then, it
really should be moved to a sysfs file or three, or even better, a
debugfs file.

I don't understand, I thought you were talking about scsi drivers, why
list all of these?  What does your patch do?

I don't know where to find these patches, care to send them to me, or
point me at a link with them?

I don't understand, if read_proc is depreciated, why can't I just remove
it from the staging drivers and then all will be fine, right?

Because if staging does count, I can't remove the interface
without breaking allmodconfig and it would take forever to convert
staging stuff. I don't have energy to do it anymore.
Mainline still have several _hard_ ->read_proc conversions.
I've tried several times and failed.

If staging doesn't count, I will break allmodconfig and all those nasty
emails will show up anyway implying that staging does count.

If the interface is depreciated, yes, I can remove it now, just let me
know and I will do so.

See commits 422f07001d6638fdde28f1909cc9162bc7f571d3..104c4fe25dc9bde823ba4591e910a77071b98ab5
Especially the first one.

Probably the best course of action is to remove proc_info code from
these drivers because the interface was deprecated for a long time.

The amount of code once removed from staging prevented me from doing
any work on them.

Looking at staging ->read_proc users this is going to be a problem for
its removal. :-(

Why is new patches going into your tree right now, during the 3.4 merge
window?  API changes should have happened weeks ago, to let others fix
up things like this.

As for the "where they are in development", they vary, but, a simple
grep should have shown you that these in-kernel drivers should also be
fixed up, or at the least, give me the heads up to let me do it for you.

Care to send me the patch that causes this problem so I can create a fix
for this?

linux-next: build failure after merge of the scsi tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 2892 bytes --]

Hi James,

After merging the scsi tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

drivers/staging/keucr/scsiglue.c:349:2: error: unknown field 'proc_info' specified in initializer
drivers/staging/rts_pstor/rtsx.c:258:2: error: unknown field 'proc_info' specified in initializer
drivers/staging/rts5139/rts51x_scsi.c:2190:2: error: unknown field 'proc_info' specified in initializer

Caused by commit 104c4fe25dc9 ("[SCSI] remove scsi_host_template::proc_info").

Since this is a staging driver, I applied these following patches:

From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Mon, 26 Mar 2012 12:07:35 +1100
Subject: [PATCH] scsi: disable broken staging driver

This driver is broken by commit 104c4fe25dc9 ("[SCSI] remove
scsi_host_template::proc_info") from the scsi tree.

Erk sorry ... I blame tglx ... I had to rebase the rc-fixes tree to get
a cc stable on to one of his patches, but I need to rebase scsi-misc as
well since it's built on top of rc-fixes.  Should be fixed for the next
go around (which is where the duplicate came from).

linux-next: build failure after merge of the scsi tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 728 bytes --]

Hi James,

After merging the scsi tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

drivers/scsi/qla4xxx/ql4_os.c:2135:6: error: redefinition of 'qla4xxx_check_relogin_flash_ddb'
drivers/scsi/qla4xxx/ql4_os.c:2081:6: note: previous definition of 'qla4xxx_check_relogin_flash_ddb' was here

Caused by a bad automatic merge when I merged the scsi tree today.  The
patch "[SCSI] qla4xxx: fix flash/ddb support" appears in both the scsi
and scsi-rc-fixes tree (as separate commits) and git has messed up the
merge.  I fixed it up by using the version of this file from the scsi
tree.

I dropped the patch for now and am circling back around with Jens to get
the necessary EXPORT_SYMBOL_GPL() tags added.

I've fixed this up in scsi-misc (by adding an explicit delay.h to
lpfc_hbadisc.c).  So hopefully the scsi branch should work for the next
build.

There are some (kernel building only) cross compilers at
http://bakeyournoodle.com/cross/ .  (yes, I know they are not PARISC
hosted :-))

That being said, I don't expect every maintainer to cross build very
much, just to react when they get problem reports. ;-)

Looks to be exactly the problem.  delay.h gets pulled into some of the
generic headers on x86, but not on ppc.

Sorry, my powerstation isn't working (orange warning light) and I can't
seem to get anyone to repair it, so I can't build for ppc anymore (which
is why this didn't get spotted on commit).
