Hi all,

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

drivers/net/ethernet/mediatek/mtk_ppe_offload.c: In function 'mtk_flow_get_wdma_info':

   94 |         };
      |         }

Caused by commit

  cf2df74e202d ("net: fix dev_fill_forward_path with pppoe + bridge")

from Linus' tree interacting with commit

  a333215e10cb ("net: ethernet: mtk_eth_soc: implement flow offloading to WED devices")

from the net-next tree.

I have applied the following merge fix patch for today.

FWIW just merged the fix, if you pull again you'll get this and a fix
for the netfilter warning about ctnetlink_dump_one_entry().

Thanks.

Felix forgot to include the update for the mtk driver in his batch it
seems.

I didn't forget. It was in the series I posted for -next but I had to 
remove it to rebase the patch onto nf (as requested by you).
The affected code didn't exist in nf.git.

Next time better if all the patches are handled through the same tree.

I will apply this patch to them merge of the net-next tree until it is
applied there.

OK, I think the issue is caused by a hole at the start of
tcp_sock_write_rx group

I will send this patch for review, thanks !

I have no idea. Maybe this arch has some unusual alignments on
u64/u32/u16 fields ?

The patch should not have changed tcp_sock_write_rx group...

My patch reduced tcp_sock_write_tx on x86_64 from 113 to 105 bytes but
I did not bother changing the assert,
because the assertion triggers if the size of the group is bigger than
the numerical value.

Hi all,

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

I wonder if it is using the system headers?  Or depends on "make headers-install"?

I tried applying the attached patch, but it doesn't make any difference.

Any idea what I've missed?  Also, why do we have duplicates of all the kernel

Hi Stephen,

I guess it was applied after you pulled net-next.
In any case, for the record, I see it there now as:

  d9ffa069e006 ("sunvnet: fix sparc64 build error after gso code split")

Thanks Stephen,

I agree that this is a correct fix.

I've tried to conduct an audit of the symbols changed in the above
mentioned patch and confirm that compilation is successful.
Your patch addresses the only failure I uncovered during that activity.

Sorry for not doing this before the patch hit net-next.

Thank you for the patch, we had the same issue in MPTCP tree when
merging net and net-next.

Small detail: should we not remove the other one -- introduced by commit
dc0b98a1758f ("ethtool: Add and use ethnl_update_bool.") -- instead? The
other one has some typos in the description and is using "!!*dst" while
it is not needed if I'm not mistaken.

In MPTCP tree for the moment, I removed the other one but I will follow
up on which one I need to discard :)
Just in case, I attached the patch I used. I can send it properly if needed.

Cheers,
Matt

Hi all,

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

drivers/net/ethernet/sfc/ptp.c:2191:35: error: 'efx_copy_channel' undeclared here (not in a function); did you mean 'efx_ptp_channel'?
 2191 |         .copy                   = efx_copy_channel,
      |                                   ^~~~~~~~~~~~~~~~
      |                                   efx_ptp_channel

Caused by commit

  54fccfdd7c66 ("sfc: efx_default_channel_type APIs can be static")

interacting with commit

  49e6123c65da ("net: sfc: fix memory leak due to ptp channel")

from the net tree.

I have added the following merge fix patch.

From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Tue, 10 May 2022 12:56:18 +1000
Subject: [PATCH] fix up for "net: sfc: fix memory leak due to ptp channel"

This is a partial revert of

  54fccfdd7c66 ("sfc: efx_default_channel_type APIs can be static")

I forgot about this warning in net :-/ we did a similar patch to net to
avoid it, Stephen's patch is correct, 
I will submit his fixup to net-next in the morning.

Hi all,

After merging the net-next tree, today's linux-next build (arm64
defconfig) failed like this:

Hi Stephen, 
the merge conflict and build failure can be avoided by the following
merge commit to net-next, already sent to Dave, hope it will be merge
in net-next soon

Hi all,

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

drivers/net/ethernet/mellanox/mlx5/core/en_tc.c:71:10: fatal error: lag.h: No such file or directory
   71 | #include "lag.h"
      |          ^~~~~~~

   13 | #include "lag.h"
      |          ^~~~~~~

Caused by commit

  3d677735d3b7 ("net/mlx5: Lag, move lag files into directory")

interacting with commit

  14fe2471c628 ("net/mlx5: Lag, change multipath and bonding to be mutually exclusive")

from the net tree.

I have applied the following merge fix patch for today.

It seems to be related to passing "le16_to_cpu(sta->he_6ghz_capa.capa)".
Probably typeof(le16_to_cpu(sta->he_6ghz_capa.capa)) goes berserk.
le16_to_cpu() is a complex macro on big-endian. I had expected to see
a similar issue on powerpc, but I don't.
Using an intermediate "u16 capa = le16_to_cpu(sta->he_6ghz_capa.capa)"
fixes the problem.

Thanks for the report, weird that I don't see it on x86. I can't look at
this in detail now, maybe later today, but I wonder if the diff below
fixes the issue?

At least it's cleaner than using FIELD_GET(), actually ath11k should be
cleaned up to use xx_get_bits() all over.

I thought it did, I get a build status email periodically with a list
of 135 builds. PPC is well represented there.

I also had to use the next-20211001 version if the bpf-next tree (since
it had been reset past the broken commit in the net-next tree).

Unfortunately, there is a typo in what you committed in bfaf03935f74
("sparc: add SO_RESERVE_MEM definition."), SO_RESEVE_MEM instead of
SO_RESERVE_MEM ...

I am sad to see the kbuild change reverted, not the net one.

13bb8429ca98 is apparently doing wrong.

Hi all,

This was not actually the net-next tree (except that the net-next tree
was updated before I merged it to include a whole new section of Linus'
tree after Linus merged the net-next tree).  Sorry about that.

Ping, again.  The net=next tree has now been merged by Linus, so has
this been fixed?  Or is Linus' tree now broken for this build?

Hi all,

After merging the net-next tree, today's linux-next build (X86_64
allnoconfig) failed like this:

Caused by commit

  342f43af70db ("iscsi_ibft: fix crash due to KASLR physical memory remapping")

Unfortunately that commit has now been merged into Linus' tree as well.

I have added the following fix patch for today.

From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Wed, 1 Sep 2021 16:31:32 +1000
Subject: [PATCH] x86: include acpi.h when using acpi functions

The removal of the include of linux/acpi.h from include/linux/iscsi_ibft.h
by commit

  342f43af70db ("iscsi_ibft: fix crash due to KASLR physical memory remapping")

exposed this build failure.

This series was supposed to go through the PCI tree. It builds on recent patches
that are in the PCI tree, but not in linux-next yet.
I mentioned this dependency in the cover letter for the last series, but forgot
it this time. Sorry.

Thank you for the report! I already sent a patch for m68knommu running into
this issue, but it seems there are other architectures that still have it.

The driver checks CONFIG_ISA_DMA_API at compile time to determine
whether isa_virt_to_bus(), set_dma_mode(), set_dma_addr(), ... are all

It seems that isa_virt_to_bus() is only implemented on most of the
architectures that set ISA_DMA_API: alpha, arm, mips, parisc and x86,
but not on m68k/coldfire and powerpc.

Before my patch, the platform driver could only be built on ARM,
so maybe we should just go back to that dependency or something
like

         depends on ARM || ((X86 || !ISA_DMA_API) && COMPILE_TEST)

for extra build coverage. Then again, it's hard to find any machine
actually using these: we have a couple of s3c24xx machines that
use the wrong device name, so the device never gets probed, the imx
machines that used to work are gone, and the ep7211-edb7211.dts
is missing a device node for it. Most likely, neither the platform nor
the ISA driver are actually used by anyone.

Hi all,

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

Thanks for reporting, I see David already fixed the issue in net-next tree.
Actually, we also need the same change for mhi_net driver to fix
7ffa7542eca6 ("net: mhi: Remove MBIM protocol").

Would it be possible to re-integrate 'marvell-mdio-ACPI' branch along
with the 2 fixes that resolve the reported depmod issue?
c88c192dc3ea - net: mdiobus: fix fwnode_mdbiobus_register() fallback case
ac53c26433b5 - net: mdiobus: withdraw fwnode_mdbiobus_register

The first one is needed to apply the second without conflicts.

Best regards,
Marcin

I think I'll go with the squashed rollback commit that removes the
problematic helper, as it may be easier to apply. I'll double check
modules_install before.

Not sure if Dave will notice this mid-thread question. It probably
doesn't matter as long as (1) doesn't introduce further transient 
build failures.

TL;DR, we need to get rid of a helper routine (introduced so that to
address review comments of v1), as it causes a depmod cycles when
fwnode_/of_/acpi_mdio are built as modules.
It can be done twofold:
a. 3 commits, i.e:
  Revert "net: mdiobus: Introduce fwnode_mdbiobus_register()"
  Revert "net/fsl: switch to fwnode_mdiobus_register"
  net: mvmdio: resign from fwnode_mdiobus_register
b. Same diff but squashed.

Please let me know your preference, so that I can do it properly up front.

Thanks,
Marcin

As far as I am aware, net and net-next are not rebased so you would need 
to submit a fixup patch against the current net-next with a proper 
Fixes: tag.

Just to understand correctly - you reverted merge from the local
branch (I still see the commits on Dave M's net-next/master). I see a
quick solution, but I'm wondering how I should proceed. Submit a
correction patch to the mailing lists against the net-next? Or the
branch is going to be reverted and I should resubmit everything as v4?

Best regards,
Marcin

Thank you for your reports. I'm currently trying to reproduce and come

LKFT test farm found this build error.

This proposed fix did not work.

Yes.
Reverting all the (6) patches in that series fixed this build problem.

I wonder if this message that I see with Arch Linux's config is related
and maybe explains the issue a little bit more:

$ curl -LSso .config https://raw.githubusercontent.com/archlinux/svntogit-packages/packages/linux/trunk/config

# do not require pahole
$ scripts/config -d DEBUG_INFO_BTF

$ make -skj"$(nproc)" INSTALL_MOD_PATH=rootfs olddefconfig all modules_install
...
depmod: ERROR: Cycle detected: acpi_mdio -> fwnode_mdio -> acpi_mdio
depmod: ERROR: Found 2 modules in dependency cycles!
...

Reverting all the patches in that series fixes the issue for me.

Cheers,
Nathan

Hi Marcin,

At my side, I got this error. I applied the suggested change, still the issue persist.

depmod: ERROR: Cycle detected: acpi_mdio -> fwnode_mdio -> acpi_mdio
depmod: ERROR: Found 2 modules in dependency cycles!
Makefile:1773: recipe for target 'modules_install' failed

Thank you for letting us know. Not sure if related, but I just found
out that this code won't compile for the !CONFIG_FWNODE_MDIO. Below
one-liner fixes it:

--- a/include/linux/fwnode_mdio.h
+++ b/include/linux/fwnode_mdio.h
@@ -40,7 +40,7 @@ static inline int fwnode_mdiobus_register(struct mii_bus *bus,
         * This way, we don't have to keep compat bits around in drivers.
         */

-       return mdiobus_register(mdio);
+       return mdiobus_register(bus);
 }
 #endif

I'm curious if this is the case. Tomorrow I'll resubmit with above, so
I'd appreciate recheck.

Thanks,
Marcin

Hi all,

Today's linux-next build (x86_64 modules_install) failed like this:

depmod: ../tools/depmod.c:1792: depmod_report_cycles_from_root: Assertion `is < stack_size' failed.

Caused by commit

62a6ef6a996f ("net: mdiobus: Introduce fwnode_mdbiobus_register()")

(I bisected to there and tested the commit before.)

The actual build is an x86_64 allmodconfig, followed by a
modules_install.  This happens in my cross build environment as well as
a native build.

$ gcc --version
gcc (Debian 10.2.1-6) 10.2.1 20210110
$ ld --version
GNU ld (GNU Binutils for Debian) 2.35.2
$ /sbin/depmod --version
kmod version 28
-ZSTD +XZ -ZLIB +LIBCRYPTO -EXPERIMENTAL

I have no idea why that commit should caused this failure.

Hi all,

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

net/bridge/br_multicast.c: In function '__br_multicast_enable_port':

Caused by commit

  a3c02e769efe ("net: bridge: mcast: split multicast router state for IPv4 and IPv6")

# CONFIG_IPV6 is not set

I have reverted that commit for today (along with commit

  3b85f9ba3480 ("net: bridge: mcast: export multicast router presence adjacent to a port")

in case it depends on a3c02e769efe).

AFAIU, each poison call must be balanced with unpoison call.
So you probably want to call unpoison_urbs right here, similarly to
wdm_release or wdm_suspend.

I have used the following merge fix patch for today.  I don't know if
this is sufficient (or even correct), but it does build.

Sorry, that commit is only in linux-next (from the usb.current tree).
I will do a merge fix up tomorrow - unless someone provides one.

Hi all,

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

drivers/usb/class/cdc-wdm.c: In function 'wdm_wwan_port_stop':
drivers/usb/class/cdc-wdm.c:858:2: error: implicit declaration of function 'kill_urbs' [-Werror=implicit-function-declaration]
  858 |  kill_urbs(desc);
      |  ^~~~~~~~~

Caused by commit

  cac6fb015f71 ("usb: class: cdc-wdm: WWAN framework integration")

kill_urbs() was removed by commit

  18abf8743674 ("cdc-wdm: untangle a circular dependency between callback and softint")

Which is included in v5.13-rc1.

I have used the net-next tree from next-20210511 for today.

Thanks.

I'll include this merge conflict in my next pull request.

Yep, applied yesterday. Given a3cf77774abf ("dma-mapping: merge <linux/dma-noncoherent.h>
into <linux/dma-map-ops.h>") is in dma-mapping tree and not yet affecting bpf-next
nor net-next, we were planning to ship bpf-next at the usual cadence this week, so it'll
be in net-next end of week for sure. (If there is urgent reason to have it in net-next
today, please let us know of course.)

Thanks,
Daniel

Yeah, it is in the bpf-next tree but not merged into the net-next tree
yet.

It actually doesn't need that or the two other internal headers.
Bjoern has a fixed, and it was supposed to be queued up according to
patchwork.

Sorry, my mistake.  I was wondering why your testing did not seem to be
affected.

I would argue against that "also" as the first commit is only in the
'net' tree right now. :-)

This is simply something I'll have to resolve the next time net is merged
into net-next.

Thanks.

If you take the net-next tree alone and do an x86_64 allmodconfig
build, it currently fails, right?

> I see the changes you applied already in linux-next/master.

Linux-next builds fine because it contains the fix patch I posted (I
added it to the net-next merge).  It needs to be explicitly fixed in the
net-next tree either using my patch or something more correct (if
necessary).

Same here FWIW. CONFIG_IPV6=m.

However, in my configuration I have CONFIG_IPV6=m, and so
fib6_rule_match is not available as a builtin.  I think that's why ld is
complaining about the undefined reference.

Changing the configuration to CONFIG_IPV6=y helps, FWIW.

Tried with both gcc 9 and gcc 10 under Debian unstable, binutils 2.35.
I usually use "make bindebpkg", but just running "make" is sufficient to
reproduce the problem, as it happens when linking vmlinux.

Cheers,

Hi Sven,

I've been trying to reproduce it with your config but I didn't
succeed. I also looked at the file after the preprocessor and it
looked good:

ret = ({ __builtin_expect(!!(ops->match == fib6_rule_match), 1) ?
fib6_rule_match(rule, fl, flags) : ops->match(rule, fl, flags); })

Note that fib4_rule_match doesn't appear as the
CONFIG_IP_MULTIPLE_TABLES is not there.

Could you share more details on how you're compiling it and what
compiler you're using??

Thanks,
Brian

Still present in 5.9-rc2 as of today, I have attached my .config for
reference.  Note that I have CONFIG_IPV6_MULTIPLE_TABLES=y, but
CONFIG_IP_MULTIPLE_TABLES is not mentioned at all there.

To build the kernel, I have now deselected IPV6_MULTIPLE_TABLES.  Not
sure why this was enabled in my .config which has grown organically over
many years.

Cheers,
       Sven

That patch is apparently already in 5.9-rc1 as commit 80fbbb1672e7, so
yes I'm still seeing it.

FWIW, I saw these errors in 5.9-rc1 today, so the fix in commit
41d707b7332f ("fib: fix fib_rules_ops indirect calls wrappers") was
apparently not sufficient.

You probably only need to include include/net/ip6_checksum.h which
contains the default implementation.

And yes, I put it on my todo list that we need to provide an s390
variant as well.

Ouch, sorry for that.

Heiko, by the way, do we want to provide a s390 version similar to the
existing csum_partial() implementation in
arch/s390/include/asm/checksum.h right away? Otherwise, I'll just take
care of the ifdeffery.

Oops, sorry that's my bad. I mixed br_netlink_tunnel with br_vlan_tunnel, the latter is compiled only
when bridge vlan filtering is defined.

Anyway, I'll post a fix ASAP.

Thanks.

Niu Xilei, you must fix this or else I will have to revert your pktgen
changes.

You cannot do direct division or modulus on 64-bit integer values,
instead you must use the various div*() helper macros so that it works
on all 32-bit systems too.

Thank you.

Yep, this is the merge resolution you will find in net-next at commit:

commit a2d6d7ae591c47ebc04926cb29a840adfdde49e6
Merge: b1daa4d19473 e69ec487b2c7

    Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
    
    The ungrafting from PRIO bug fixes in net, when merged into net-next,
    merge cleanly but create a build failure.  The resolution used here is

Please check if following patch makes it work: https://marc.info/?l=linux
-netdev&m=157670971305055&w=2

Unfortunately, I don't have an ARM compiled tree right now to test.

Hi all,

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

I have used the net-nest tree from next-20191218 for today.

Hi Stephen

I just received the 0-day about this. I did not know David had merged
it!

What you have works. So:

Reviewed-by: Andrew Lunn <andrew@lunn.ch>

The nicer way is a bit bigger. Is this too big to go in via you?
Should i submit it via netdev, and you can drop your fix once this
arrives?

Subject: [PATCH] net: ethernet: emac: Fix phy mode type

Pass a phy_interface_t to of_get_phy_mode(), by changing the type of
phy_mode in the device structure. This then requires that
zmii_attach() is also changes, since it takes a pointer to phy_mode.

No worries. Thanks for candid answer. I just wanted to make sure there
are no hard feelings and I can engage your expertise effectively in
the future for kbuild stuff to ensure issues like this don't slip
through, if we ever have to do anything like this for BPF-related
things again. I'll keep CC'ing you and will add kbuild ML as well.
Thanks!

I could have pointed it out if I had noticed
it in the review process.

I actually noticed your patch by Stephen's
former email.  (i.e. when it appeared in linux-next)

(I try my best to check kbuild ML, and also search for
my name in LKML in case I am explicitly addressed,
but a large number of emails fall off my filter)

It was somewhat too late when I noticed it.
Of course, I still could email you afterward, or even send a patch to btf ML,
but I did not fix a particular instance of breakage
because there are already the same type of breakages in code base.

Then, I applied the all-or-nothing checker because I thought it was
the only way to address the root cause of the problems.

I admit I could have done the process better.
Sorry if I made people uncomfortable and waste time.

Thanks.

Was there a specific reason to wait until this would break during
Stephen's merge, instead of giving me a heads up (or just replying on
original patch) and letting me fix it and save everyone's time and
efforts?

Either way, I've fixed the issue in
https://patchwork.ozlabs.org/patch/1158620/ and will pay way more
attention to BASH-specific features going forward (I found it pretty
hard to verify stuff like this, unfortunately). But again, code review
process is the best place to catch this and I really hope in the
future we can keep this process productive. Thanks!

I replaced ${@:2} with shift and ${@}, I hope that's a correct fix,
but if you think it's not, please reply on the patch and let me know.

Hi Stephen,

Sorry about this breakage. Indeed, ${@:2} is BASH-specific extension, 
unfortunately. I'm verifying a simple fix with shift and $@, I'll post 
and CC you as soon as I've verified everything.

With that your temporary fix shouldn't be necessary.

I knew that they were using bash-extension
in the #!/bin/sh script.  :-D


In fact, I wrote my patch in order to break their code
and  make btf people realize that they were doing wrong.

But, this is a temporary fix only for linux-next.

scripts/link-vmlinux.sh does not need to use the
bash-extension ${@:2} in the first place.

I hope btf people will write the correct code.

Thanks.

Hi all,

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

scripts/link-vmlinux.sh: 74: Bad substitution

Caused by commit

  341dfcf8d78e ("btf: expose BTF info through sysfs")

interacting with commit

  1267f9d3047d ("kbuild: add $(BASH) to run scripts with bash-extension")

from the kbuild tree.

The change in the net-next tree turned link-vmlinux.sh into a bash script
(I think).

I have applied the following patch for today:

Hi all,

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

ld: drivers/net/ethernet/stmicro/stmmac/stmmac_pci.o: in function `.stmmac_pci_remove':
stmmac_pci.c:(.text.stmmac_pci_remove+0x68): undefined reference to `.clk_unregister_fixed_rate'
ld: drivers/net/ethernet/stmicro/stmmac/stmmac_pci.o: in function `.intel_mgbe_common_data':
stmmac_pci.c:(.text.intel_mgbe_common_data+0x2a8): undefined reference to `.clk_register_fixed_rate'

Caused by commit

  190f73ab4c43 ("net: stmmac: setup higher frequency clk support for EHL & TGL")

CONFIG_COMMON_CLK is not set for this build.

I have added the following patch for today:

Actually, I have rewound my tree and am starting from the merge of the
rdma tree again, so hopefully it should all be good today.

Actually , I get it now, "Fixup to build SIW issue" is really just a
fixup for the net-next and rdma trees merge ... OK, I will fix that up
tomorrow.  Sorry for my confusion.

I have "Fixup to build SIW issue" from Leon (which switches to using
in_dev_for_each_ifa_rcu) included in the rmda tree merge commit because
without that the rdma tree would not build for me.  Are you saying that
I don't need that at all, now?

? I'm confused.. 

rdma.git builds fine stand alone (I hope!)

If you merge it with netdev then the above patch is needed afer the
merge as netdev changed to ifa_rcu

I just did this a few hours ago to make and test the patch I sent
above..

So today this failed to build after I merged the rdma tree (previously
it didn;t until after the net-next tree was merged (I assume a
dependency changed).  It failed because in_dev_for_each_ifa_rcu (and
in_dev_for_each_ifa_rtnl) is only defined in a commit in the net-next
tree :-(

I have disabled the driver again.

Hum. There is no rcu lock held here and we can't use RCU anyhow as
siw_listen_address will sleep.

I think this needs to use rtnl, as below. Bernard, please urgently
confirm. Thanks

I had the same question, because I have this fix for a couple of days already.

Hi all,

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

drivers/infiniband/sw/siw/siw_cm.c: In function 'siw_create_listen':
drivers/infiniband/sw/siw/siw_cm.c:1978:3: error: implicit declaration of function 'for_ifa'; did you mean 'fork_idle'? [-Werror=implicit-function-declaration]

   for_ifa(in_dev)
                  ^
                  ;
   {
   ~

Caused by commit

  6c52fdc244b5 ("rdma/siw: connection management")

from the rdma tree.  I don't know why this didn't fail after I mereged
that tree.

I have marked that driver as depending on BROKEN for today.

I don't think so.  I'm assuming something like this is necessary

at a minimum, though it may be saner to #ifdef support for the SiFive clock
driver as that's only useful on some systems.  Assuming I can reproduce the
build failure (which shouldn't be too hard), I'll send out a patch that adds a
Kconfig for the FU540 clock driver to avoid adding a COMMON_CLK dependency for
all MACB systems.

I am still reverting that commit.  Has this problem been fixed in some
subtle way?

Hi all,

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

Whilst out walking the dog I realised I’m a moron.

The CTINFO_MODE_FOO is only used within module, it shouldn’t even be exposed
to user space.

I’ll send a patch shortly.  Sorry, I’m pretty embarrassed at how something so
apparently simple on the surface has had so many issues.

Cheers,

Kevin D-B

Hi David,

Thanks for that.  Owe you a beer!

Thinking out loud, doesn’t this also require:

#include <linux/const.h>


Or at least iproute2 would need to know about _BITUL as it doesn’t at present.
Which also means iproute2’s Linux uapi shadow would also have to import
linux/const.h.  Or have I got wrong end of stick?

Cheers,

Kevin

Greetings!

As the guilty party in authoring this, and also pretty new around here
I’m wondering what I need to do to help clean it up?

Stephen, thanks for the fixup - is that now in the tree or do I need to submit
a fix via the normal net-next channel so it gets picked up by the iproute2 people
who maintain a local copy of the uapi includes?

Thanks for the pointers.

I am confused as to why I didn’t hit this issue when I built & run tested locally off
the net-next tree.

This is what other actions do e.g. tc_skbedit.  Can you advise what I should do instead?

I just took a look at
include/uapi/linux/tc_act/tc_ctinfo.h


I just wondered why the following can be compiled:

struct tc_ctinfo {
        tc_gen;
};


Then, I found 'tc_gen' is a macro.

#define tc_gen \
        __u32                 index; \
        __u32                 capab; \
        int                   action; \
        int                   refcnt; \
        int                   bindcnt



What a hell.

My commit correctly blocked the broken UAPI header, Hooray!

People export more and more headers that
are never able to compile in user-space.

We must block new breakages from coming in.


BIT() is not exported to user-space
since it is not prefixed with underscore.


You can use _BITUL() in user-space,
which is available in include/uapi/linux/const.h


Thanks.

My fault, I should have tested more kernel configs. This fails with
CONFIG_RETPOLINE=n

A fix has been posted here:

Jeff is out, so I just opted to email a fix to netdev. I hope this is acceptable.

I opted to essentially revert the patch that moved code to i40e_ethtool_stats.h, rather than anything fancier, since it was fast, and correct.

There was a suggestion to only move the one offending function, but I felt that it was better to move everything back into the .c files.

Thanks,
Jake

Hi all,

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

In file included from drivers/net/ethernet/intel/i40e/i40e_ethtool.c:9:
drivers/net/ethernet/intel/i40e/i40e_ethtool.c: In function '__i40e_add_stat_strings':
drivers/net/ethernet/intel/i40e/i40e_ethtool_stats.h:193:20: error: function '__i40e_add_stat_strings' can never be inlined because it uses variable argument lists
 static inline void __i40e_add_stat_strings(u8 **p, const struct i40e_stats stats[],
                    ^~~~~~~~~~~~~~~~~~~~~~~

Caused by commit

  8fd75c58a09a ("i40e: move ethtool stats boiler plate code to i40e_ethtool_stats.h")

It is not clear this patch has any value anyway as the moved functions
are only used in the file they were moved from.

I reverted that commit for today.

The same problem would exist in drivers/net/ethernet/intel/i40evf (where
a lot of code is duplicated from drivers/net/ethernet/intel/i40e) except
that this function is not declared inline there.
Luckily, i40e_ethtool_stats.h is only included my one file
drivers/net/ethernet/intel/i40evf/i40evf_ethtool.c, otherwise there
would be multiple copies of __i40e_add_stat_strings().

Surely there is some scope for factoring out some common code between
these two drivers?

My bad, I am working on fixing this now.

Some of the lines in tools/lib/bpf/btf.[ch] were duplicated (they existed
on both sides of the merge).

I have used the net-next tree from next-20180802 for today.

Looks like this is fixed in today's tree by not building bpfilter when
CC cannot link against user libraries.  Unfortunately this means that
it will never be built by my infrastructure (since all my compilers are
minimal cross compilers) :-(

I may look into getting a different set of compilers (or doing my
PowerPC builds natively).

yeah. that's another option.
Sorry for delay. networking folks are traveling to netconf.
The issue is being discussed here:
https://patchwork.ozlabs.org/patch/921597/

Currently we're thinking how to add a check that hostcc's arch
is equal to cross-cc target arch and ideally equal to arch
of the host where it will be run.

Still happened today.  My guess is that bpfilter_umh needs to be built
with the kernel compiler (not the host compiler - since ir is meant to
run on the some machine as the kernel, right?) but will require the
kernel architecture libc etc

right.
Also, since we do:
fp->jit_requested = ebpf_jit_enabled();
and
static inline bool ebpf_jit_enabled(void)
{
   return bpf_jit_enable && bpf_jit_is_ebpf();
}
and JIT_ALWAYS_ON depends on CONFIG_HAVE_EBPF_JIT
we should be good.

But if jit_subprogs() fails, then the err is propagated at the end of
the function (the 'return err' I mean).

jit_subprogs() can fail, so err = -ENOTSUPP is necessary.

Looks fine to me. The only thing I was wondering was whether we should
set err = -ENOTSUPP here above, but actually that is unnecessary. Say,
if for some reason we would missed to set prog->jit_requested bit under
CONFIG_BPF_JIT_ALWAYS_ON, we would return 0 here even if we would have
calls in the prog. But that also means for bpf_prog_load() that right
after bpf_check() returned, we would go into bpf_prog_select_runtime()
since prog->bpf_func is still NULL at that point, and bpf_int_jit_compile()
from there wouldn't do anything either since prog->jit_requested was
not set in the first place, therefore we return with -ENOTSUPP from
there. So the resolution looks fine to me, we can leave it as is.

right, as I was trying to say one extra hunk would be needed for net-next.
I was reading this patch:
diff --git a/kernel/bpf/verifier.c b/kernel/bpf/verifier.c

but below should be fine too.
Will test it asap.

That doesn't fix it, because then you'd need to expose
interpreters_args as well and obviously that can't be right.

Instead, we should never call bpf_patch_call_args() when JIT always on
is enabled.  So if we fail to JIT the subprogs we should fail
immediately.

This is the net --> net-next merge resolution I am about to use to fix
this:

...

 +	struct bpf_prog *prog = env->prog;

that's due to 'endif' from 290af86629b2 needs to be moved above
bpf_patch_call_args() definition.
There is another fixup needed for net-next.
I'll send a follow up patch when net gets merged into net-next.

Hi all,

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

kernel/bpf/verifier.o: In function `bpf_check':
verifier.c:(.text+0xd86e): undefined reference to `bpf_patch_call_args'

Caused by commit

  1ea47e01ad6e ("bpf: add support for bpf_call to interpreter")

interacting with commit

  290af86629b2 ("bpf: introduce BPF_JIT_ALWAYS_ON config")

from the bpf and net trees.

I have just reverted commit 290af86629b2 for today.  A better solution
would be nice (lie fixing this in a merge between the net-next and net
trees).

Hi Stephen, sorry about those merges today.  The proper fix is queued
up in patchwork for when net-next is merged in to net:

http://patchwork.ozlabs.org/patch/851063/

I will CC you on patches which may cause/fix merge trouble in the
future, often the information about how to resolve the conflict is
not part of the commit message.

Sorry I didn't think about CCing you earlier!

Hi all,

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

net/dsa/slave.c: In function 'dsa_slave_create':
net/dsa/slave.c:1191:18: error: 'struct dsa_slave_priv' has no member named 'phy'

My fault, I should have fuzzed the configuration before posting.

Paolo, it seems this struct member should be placed outside of
IP_MULTIPLE_TABLES protection, since users can insert custom
local routes even without that set.

So I'm installing the following fix for this:

====================
[PATCH] ipv4: Move fib_has_custom_local_routes outside of IP_MULTIPLE_TABLES.

Hi all,

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

net/ipv4/fib_frontend.c: In function 'fib_validate_source':
net/ipv4/fib_frontend.c:411:16: error: 'struct netns_ipv4' has no member named 'fib_has_custom_local_routes'

   net->ipv4.fib_has_custom_local_routes = true;
            ^

Caused by commit

  6e617de84e87 ("net: avoid a full fib lookup when rp_filter is disabled.")

This build has CONFIG_IP_MULTIPLE_TABLES unset.

I have reverted that commit for today.

Hi all,

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

arch/arm/boot/dts/rk3228-evb.dtb: ERROR (phandle_references): Reference to non-existent node or label "phy0"

Caused by commit

Its possible that the error is caused by an interaction with another
commit, but I could not find anything obvious.  I have reverted that
commit for today.

CONFIG_BPF=y
# CONFIG_BPF_SYSCALL is not set

I have used the net-next tree from next-20170717 for today.

Good catch, I'll fix this up!

Does this need to be 0x4033 (or something)?

Indeed. I added the architecture specific versions in patch

  http://patchwork.ozlabs.org/patch/765238/

That fixes the powerpc build for me. The new option is now
defined in every file that also defines the last added such
option SCM_TIMESTAMPING_OPT_STATS. Apologies for
missing this earlier.

I've just pushed the following, thanks for the report:

====================
net: Define SCM_TIMESTAMPING_PKTINFO on all architectures.

A definition was only provided for asm-generic/socket.h
using platforms, define it for the others as well

Hi all,

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

net/socket.c: In function 'put_ts_pktinfo':
net/socket.c:695:28: error: 'SCM_TIMESTAMPING_PKTINFO' undeclared (first use in this function)
  put_cmsg(msg, SOL_SOCKET, SCM_TIMESTAMPING_PKTINFO,
                            ^

Caused by commit

  aad9c8c470f2 ("net: add new control message for incoming HW-timestamped packets")

This probably broke every architecture that has its own
arch/<arch>/include/uapi/asm/socket.h that does not include
include/uapi/asm-generic/socket.h :-(

I have used the net-next tree from next-20170519 for today.

This fix up is now needed when the vfs tree is merged with Linus' tree.

ACK - smc_splice_read() is just a place holder at the moment. Its implementation for AF_SMC will follow.

Hi all,

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

net/smc/af_smc.c: In function 'smc_splice_read':

from the vfs tree.

I applied the following merge fix patch which could well be incorrect ...

I'd suggest you do a merge of next-next with the qcom/soc-2 branch that
we have in arm-soc and resolve the conflict in the merge, then send
a pull request with the merge to davem.

Alternatively, in case Linus merges net-next before we get that fix
in, I could send Stephen's fix to Linus along with the pull requests.

Sorry for not spotting this issue earlier, I missed Andy's second pull
request towards arm-soc and thought the SMD changes missed this cycle.


Your patch looks good, but I'm not sure how we should approach the merge
window; Andy can't pick the patch because he doesn't have the qrtr code
and David doesn't have the SMD patches coming through Andy.

FWIW, Reviewed-by: Bjorn Andersson <bjorn.andersson@linaro.org>


I assume we could have the QRTR go through Andy and arm-soc, with
David's approval and this fix squashed in. But we're running rather late
in this cycle, perhaps we should just back the QRTR patches out and I
can respin and resend them after the merge window (for v4.8 instead)?

Suggestions are welcome.

Regards,
Bjorn

Thanks for fixing this up.  I'll work with Bjorn to get this resolved.
I'll have something up for tomorrow's next pull.

Hi all,

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

  b853cb9628bf ("soc: qcom: smd: Make callback pass channel reference")

Like Stephen said it had been there for a couple of days already at the
time it was reported; I happened to be busy at the time it came up so
wasn't looking at the build reports myself.  If you've got a fix please
get it submitted ASAP, having common test configurations broken for any
length of time does get disruptive.

Interesting that no one spoke up until just a week ago.  I have a fix

This is still present, it's been breaking ARM allmodconfig builds for
about two weeks now.

I sent a patch, pretty sure we can use msleep() here rather than
a wasteful mdelay().

Jeff, please have your folks look into this.  Probably just a simple

Hi all,

[A report from Mark's buildbot]

After merging the net-next tree, today's linux-next build (arm
allmodconfig) failed like thisi (this has actually been failing for a
few days, now):

ERROR: "__bad_udelay" [drivers/net/ethernet/intel/ixgbe/ixgbe.ko] undefined!

Caused by commit

  49425dfc7451 ("ixgbe: Add support for x550em_a 10G MAC type")

arm only allows udelay()s up to 2 milliseconds.  This commit
adds a 5 ms udelay in ixgbe_acquire_swfw_sync_x550em_a() in
drivers/net/ethernet/intel/ixgbe/ixgbe_x550.c.

Hi Dave,

Perhaps I wasn't clear enough in the title I've provided for the fixing patch,
but I've sent it yesterday and it's marked as 'under review' for net-next.
The patch is "bnx2x: Add missing HSI for big-endian machines".

Sorry about all the noise.

Yuval and Ariel, you _MUST_ fix this.

This build failure has been in the tree for 24 hours and I haven't heard anything
from you two yet.

If this persists for another day I'm reverting all of your changes.

Thanks Stephen, it's correct and I'll make sure I do this when
I merge net into net-next.

Thanks, I will get that tomorrow.  I must try to remember to check to
see if you have added fixes to your tree when I get these errors (not
that it happens all that often).

====================
[PATCH] route: fix breakage after moving lwtunnel state

__recnt and related fields need to be in its own cacheline for performance
reasons. Commit 61adedf3e3f1 ("route: move lwtunnel state to dst_entry")
broke that on 32bit archs, causing BUILD_BUG_ON in dst_hold to be triggered.

This patch fixes the breakage by moving the lwtunnel state to the end of
dst_entry on 32bit archs. Unfortunately, this makes it share the cacheline
with __refcnt and may affect performance, thus further patches may be
needed.

Hi all,

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

In function 'dst_hold',
    inlined from '__ipv6_dev_ac_dec' at /home/sfr/next/next/net/ipv6/anycast.c:328:2:

And many more :-(

I have used the net-next tree from next-20150821 for today.

Subject: [PATCH 1/2] lwtunnel: Fix the sparse warnings in fib_encap_match
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When CONFIG_LWTUNNEL config is not enabled, the lwtstate_free() is not
declared in lwtunnel.h at all. However, even in this case, the function
is still referenced in fib_semantics.c so that there appears the
following sparse warnings:

net/ipv4/fib_semantics.c:553:17: error: undefined identifier 'lwtstate_free'
  CC      net/ipv4/fib_semantics.o
  net/ipv4/fib_semantics.c: In function ¡fib_encap_match¢:
  net/ipv4/fib_semantics.c:553:3: error: implicit declaration of function ¡lwtstate_free¢ [-Werror=implicit-function-declaration]
  cc1: some warnings being treated as errors
  make[1]: *** [net/ipv4/fib_semantics.o] Error 1
  make: *** [net/ipv4/fib_semantics.o] Error 2

To eliminate the error, we define an empty function for lwtstate_free()
in lwtunnel.h when CONFIG_LWTUNNEL is disabled.

Hi all,

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

net/ipv4/fib_semantics.c: In function 'fib_encap_match':
net/ipv4/fib_semantics.c:553:3: error: implicit declaration of function 'lwtstate_free' [-Werror=implicit-function-declaration]

Caused by commit

  df383e6240ef ("lwtunnel: fix memory leak")

CONFIG_LWTUNNEL is not set for this build.

I reverted that commit for today.

Rename these to 'enic_*' to avoid the conflict with the functiosn of
the same name in the snic scsi driver.

Hi all,

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

drivers/net/ethernet/mellanox/mlx5/core/main.c: In function 'mlx5_irq_set_affinity_hint':
drivers/net/ethernet/mellanox/mlx5/core/main.c:474:2: error: implicit declaration of function 'cpumask_set_cpu_local_first' [-Werror=implicit-function-declaration]
  err = cpumask_set_cpu_local_first(i, numa_node, priv->irq_info[i].mask);
  ^

Caused by commit db058a186f98 ("net/mlx5_core: Set irq affinity hints")
interacting with commit f36963c9d3f6 ("cpumask_set_cpu_local_first =>
cpumask_local_spread, lament") from Linus' tree.

I have applied the following merge fix patch (Dave, you could do this
by back merging commit f36963c9d3f6 from Linus' tree - which is based
on v4.1-rc2 if that worries you).  Please yell if this is not correct
(it does build).

Hi all,

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

drivers/net/usb/cdc_ncm.c: In function 'cdc_ncm_fill_tx_frame':
drivers/net/usb/cdc_ncm.c:1187:2: error: too few arguments to function 'usbnet_set_skb_tx_stats'

Caused by a bad merge between commits 1e9e39f4a298 ("usbnet: Fix
tx_packets stat for FLAG_MULTI_FRAME drivers") and 7a1e890e2168
("usbnet: Fix tx_bytes statistic running backward in cdc_ncm") form the
net tree and commit 6588af614e7b ("usbnet: Fix tx_packets stat for
FLAG_MULTI_FRAME drivers") from the net-next tree.  (Presumably,
6588af614e7b was cherry-picked as a bug fix.  So, Dave, something to
watch for if you merge net into net-next.)

That's no longer possible as my tree never rebases and the commits are pushed
out already.

Another solution to this set of conflicts, is therefore necessary.

These are my changes.  But I think it would be much better if any aio-related
changes like this one we be one on top of my changes in Al's iocb branch,
there have been various changes, and it would be better to review and
commit the changes on top of it instead of carrying the changes as fixups.

Nevermind the actual test coverage..

Hi all,

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

net/mpls/af_mpls.c: In function 'resize_platform_label_table':
net/mpls/af_mpls.c:767:4: error: implicit declaration of function 'vzalloc' [-Werror=implicit-function-declaration]
    labels = vzalloc(size);
    ^

Caused by commit 7720c01f3f59 ("mpls: Add a sysctl to control the size
of the mpls label table").

I have added this commit for today:

From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Thu, 5 Mar 2015 13:37:05 +1100
Subject: [PATCH] mpls: using vzalloc requires including vmalloc.h

Fixes this build error:

net/mpls/af_mpls.c: In function 'resize_platform_label_table':
net/mpls/af_mpls.c:767:4: error: implicit declaration of function 'vzalloc' [-Werror=implicit-function-declaration]

Yeah, this was fixed with the follow on patch:

commit c07a213db1437a8fd40c328e6a2c426723caec65
Author: Carolyn Wyborny <carolyn.wyborny@intel.com>
Date:   Tue Feb 10 07:33:15 2015 +0000

    i40e: Fix for stats init function call in Rx setup
    
    This patch fixes indentation issue and error found in argument
    reported by static analysis.  Without this patch, sparse and other
    static analysis errors will be found.

Hi all,

After merging the net-next tree, today's linux-next build (i386
allmodconfig and a few others) failed like this:

drivers/net/ethernet/intel/i40e/i40e_txrx.c: In function 'i40e_setup_rx_descriptors':
drivers/net/ethernet/intel/i40e/i40e_txrx.c:1101:3: error: incompatible type for argument 1 of '__seqcount_init'
include/linux/seqlock.h:53:20: note: expected 'struct seqcount_t *' but argument is of type 'seqcount_t'

Caused by commit 638702bd59a3 ("i40e/i40evf: Add call to u64_stats_init
to init").

Discovered after the release, so no fix done.

The indentation of the lines added by that patch is also a bit strange.

Hi all,

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

lib/rhashtable.c: In function 'rhashtable_walk_next':
lib/rhashtable.c:1002:3: error: implicit declaration of function 'ERR_PTR' [-Werror=implicit-function-declaration]
   return ERR_PTR(-EAGAIN);

Caused by commit f2dba9c6ff0d ("rhashtable: Introduce
rhashtable_walk_*"). See Rule 1 in Documentation/SubmitChecklist.

I have added the following fix patch for today:

Or he did so after I fetched his tree this morning.  Either way, I
assume it will be fixed tomorrow.

it seems Dave forgot to push out his net-next tree, but in theory it should contain a fix for it.

Hi all,

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

In file included from net/bridge/br.c:22:0:
include/net/switchdev.h:73:1: error: expected identifier or '(' before '{' token

 static inline int call_netdev_switch_notifiers(unsigned long val, struct net_device *dev,
                   ^

Caused by commit 03bf0c281234 ("switchdev: introduce switchdev notifier").

I have used the net-next tree from next-20150116 for today.  I also had
to use the bluetooth tree from next-20150116 as it was fast forwarded
to be the same as the net-next tree today.

Hi all,

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

Caused by commit cd91cc5bdddf ("doc: fix the compile error of

of struct in6_pktinfo depends on __USE_GNU being defined (at least, I
think that is the problem).

I have reverted that commit for today.

My powerpc allyesconfig build also produced this:

Thanks, so hopefully I won't need my patch for very long.

Happy new 2015 Stephen...

[ The last days I revived my linux-next build-script inspired by
willing to test block-loop-mq v3 patchset against next-20141231 ]

Just FYI...

Richard posted a new patch-series "[PATCH net-next 0/7] Fixing the
"Time Counter fixes and improvements" on linux-nextdev fixing this.

Hi all,

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

drivers/net/ethernet/mellanox/mlx4/en_clock.c: In function 'mlx4_en_init_timestamp':
drivers/net/ethernet/mellanox/mlx4/en_clock.c:249:2: error: implicit declaration of function 'CLOCKSOURCE_MASK' [-Werror=implicit-function-declaration]
  mdev->cycles.mask = CLOCKSOURCE_MASK(48);
  ^
drivers/net/ethernet/mellanox/mlx4/en_clock.c:257:3: error: implicit declaration of function 'clocksource_khz2mult' [-Werror=implicit-function-declaration]
   clocksource_khz2mult(1000 * dev->caps.hca_core_clock, mdev->cycles.shift);
   ^
drivers/net/ethernet/intel/ixgbe/ixgbe_ptp.c: In function 'ixgbe_ptp_start_cyclecounter':
drivers/net/ethernet/intel/ixgbe/ixgbe_ptp.c:796:2: error: implicit declaration of function 'CLOCKSOURCE_MASK' [-Werror=implicit-function-declaration]
  adapter->cc.mask = CLOCKSOURCE_MASK(64);
  ^

Presumably caused by commit 74d23cc704d1 ("time: move the
timecounter/cyclecounter code into its own file").

I added the following commit for today:

Hi all,

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

drivers/net/ethernet/chelsio/cxgb4vf/built-in.o:(.opd+0x630): multiple definition of `t4_bar2_sge_qregs'
drivers/net/ethernet/chelsio/cxgb4/built-in.o:(.opd+0x14d0): first defined here

(.text+0x9220): multiple definition of `.t4_bar2_sge_qregs'
drivers/net/ethernet/chelsio/cxgb4/built-in.o:(.text+0x24e24): first defined here

Caused by commit e85c9a7abfa4 ("cxgb4/cxgb4vf: Add code to calculate T5
BAR2 Offsets for SGE Queue Registers") which added both versions.  :-(

I have applied this fir patch for today (including the subject
typo :-)):

Thanks Stephen, I integrated this into the merge commit when
I merge net into net-next just now.

After whish I get this from an x86_64 allmodconfig build:

ERROR: "br_nf_core_fini" [net/bridge/bridge.ko] undefined!
ERROR: "br_netfilter_rtable_init" [net/bridge/bridge.ko] undefined!
ERROR: "br_nf_core_init" [net/bridge/bridge.ko] undefined!

So I gave up :-(

I have used the net-next tree from next-20140926 for today.

Hi all,

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

ERROR: ".ipv6_dev_get_saddr" [drivers/scsi/cxgbi/libcxgbi.ko] undefined!
ERROR: ".ip6_route_output" [drivers/scsi/cxgbi/libcxgbi.ko] undefined!

Caused by commit fc8d0590d914 ("libcxgbi: Add ipv6 api to driver").
Presumably some missing Kconfig dependency (this build does not have
CONFIG_IPV6 enabled) or it needs some #ifdef guarding.

I have used the net-next tree from next-20140717 for today.

I accidentally left this in from driver debugging and it is not
necessary.  Patch to follow.

Thank you.
It is correct.
I think Dave was about to push the same fix to net-next.
You're too fast :)

After merging the net-next tree, today's linux-next build (sparc64
defconfig) failed like this:

ERROR: "of_mdiobus_link_phydev" [drivers/net/phy/libphy.ko] undefined!

Caused by commit 86f6cf41272d ("net: of_mdio: add

CONFIG_PHYLIB=m for this build.

I have reverted that commit for today.

Hi all,

After merging the net-next tree, today's linux-next build (arm
multi_v7_defconfig, gcc 4.6.3) failed like this:

drivers/built-in.o: In function `cdc_ncm_get_coalesce':
ak8975.c:(.text+0x1ac994): undefined reference to `__aeabi_uldivmod'

(The file name above seems to be rubbish, the above function is in
drivers/net/usb/cdc_ncm.c)

Probably caused by commit 6c4e548ff366 ("net: cdc_ncm: use ethtool to
tune coalescing settings").  I assume that there are some 64 bit
divides in that function.

I have used the net-next tree from next-20140516 for today.

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

In file included from net/core/dev.c:134:0:
include/linux/if_macvlan.h: In function 'macvlan_count_rx':
include/linux/if_macvlan.h:68:3: error: invalid use of undefined type 'struct vlan_pcpu_stats'
   pcpu_stats = this_cpu_ptr(vlan->pcpu_stats);
   ^

And lots more.

Caused by commit cdf3e274cf1b ("macvlan: unify macvlan_pcpu_stats and
vlan_pcpu_stats");

I have reverted that commit for today.

Sorry for this breaking in two different ways two days in a row :-/

I hope with the following commit everything is good now:

Me too, it's unreasonable and of dubious value.

In fact, manually editing these files carries a far greater risk of
causing missing entries than sorting could possibly cure.

Also, missing entires isn't much of a problem to begin with, compilers
are rather good at finding the problem.

Surely sorting doesn't cure missing entries. Also sorting can at most
reduce merge conflicts, not take them out entirely.

That's a manual operation, and therefore disqualified.

Edit in vi put cursor on the first line to be sorted and type !}sort
(assuming there is a nice blank line at the end).

So we need a script for that (adding Joe), that adds the "generic-y += ..."
line to all architectures that don't have it yet, and don't provide their
own version.

Not keeping them sorted causes merge conflicts and duplicate/missing
entries.

So what I did was something like:

for i in arch/*/include/asm/Kbuild
do
	echo "generic-y += preempt.h" >> $i
done

Whoever is going to hand edit all gazillion archs for changes like that?
And sort(1) is annoying in that it doesn't do in-place sort; you'll end
up with empty files if you try the naive thing.

Worse most of those Kbuild files include other random garbage, which
makes automated sorting harder still.

So unless there's a sane and easy way to keep it sorted; I'm going to
ignore that rule.

Please keep them sorted.

Yes, Peter violated that too, when adding preempt.h.

The author believed that putting a header file in asm-generic/
makes it get used automatically by architectures which lack
that header file.

At the very least we have to add a generic-y entry for it to
arch/${ARCH}/include/asm/Kbuild

I'll try to fix this up, thanks for the report.

Hi all,

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

In file included from include/linux/hashtable.h:12:0,
                 from include/linux/elevator.h:5,
                 from include/linux/blkdev.h:222,

 #include <asm/hash.h>
                      ^

And many more ...

Caused by commit 71ae8aac3e19 ("lib: introduce arch optimized hash
library").  Presumably this would break any architecture other than
x86 :-(

I have used the net-next tree from next-20131217 for today.

Hi all,

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

net/9p/trans_rdma.c:724:15: error: 'rdma_cancelled' undeclared here (not in a function)
  .cancelled = rdma_cancelled,
               ^

Caused by commit 59ea52dc461e ("net: trans_rdma: remove unused function")
interacting with commit d538a4ba906a ("net/9p: link rdma_cancelled in
with trans_module") from the v9fs tree.

I just reverted that net-next tree commit for today.

ppc64_defconfig) failed like this:

drivers/net/ethernet/ibm/ehea/ehea_main.c: In function 'ehea_proc_rwqes':
drivers/net/ethernet/ibm/ehea/ehea_main.c:728:5: error: too few arguments to function '__vlan_hwaccel_put_tag'
include/linux/if_vlan.h:237:31: note: declared here

Caused by commit 86a9bad3ab6b ("net: vlan: add protocol argument to
packet tagging functions").  Grep is your friend.  :-(

drivers/net/ethernet/ibm/ehea/ehea_main.c: In function 'ehea_setup_single_port':
drivers/net/ethernet/ibm/ehea/ehea_main.c:3027:9: error: expected expression before '|' token

Caused by commit f646968f8f7c ("net: vlan: rename NETIF_F_HW_VLAN_*
feature flags to NETIF_F_HW_VLAN_CTAG_*").

I have used the net-net tree from next-20130419 for today.

Its entirely up to Dave how/if he fixes this up.  He could just leave it
to Linus, though he would usually pull the net tree into the net-next
tree after Linus merges the net tree - in which case, this should be
fixed in that merge.

i.e. ask Dave :-)

thank you very much for taking care of this.
However, as I wrote to David in the pull request which generated this noise
(http://patchwork.ozlabs.org/patch/237363/), I am now going to send a second
pull request which fixes this problem properly and adds the related kernel doc.

Your patch looks good, but I'd prefer to send my already prepared pull request.

Is it ok with you?

Cheers,

The net tree commit should be simply reverted, yes.

Hi all,

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

net/ipv6/xfrm6_policy.c: In function 'xfrm6_dst_destroy':
net/ipv6/xfrm6_policy.c:238:6: error: 'struct rt6_info' has no member named 'n'
net/ipv6/xfrm6_policy.c:239:28: error: 'struct rt6_info' has no member named 'n'

Caused by commit 887c95cc1da5 ("ipv6: Complete neighbour entry removal
from dst_entry") interacting with commit 18cf0d0784b4 ("xfrm: release
neighbor upon dst destruction") from the net tree.

I assume that the problem fixed by the net tree commit is fixed some
other way in the net-next tree, so I reverted the net tree commit.

Sorry for that, it will be better to use pci_physfn to access this

Hi all,

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

only defined if CONFIG_PCI_ATS is set.

I have reverted that commit for today.

Sorry about that. I missed the dependency of the new driver on phylib. A 
fix for this problem is already in net-next, see commit 215029375c83.

Thanks, Christian

This was actually yesterday's linux-next - I guess it is fixed by commit
215029375c83 ("asix: AX88172A driver depends on phylib") in today's tree.

Hi all,

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

drivers/net/usb/qmi_wwan.c:381:13: error: 'qmi_wwan_unbind_shared' undeclared here (not in a function)

Caused by a bad automatic merge between commit 6fecd35d4cd7 ("net:

qmi_wwan: bind to both control and data interface") from the net-next
tree.

Not directly germane but I've been sending patches for this to the x86
guys for a little while though they're doing a /dev/null impression.

The other option is that the clock API stubs itself out when not enabled
which is going into mainline (not sure quite where it is at the minute).

These sort of per-arch APIs should be a legacy thing, hopefully we'll
manage to squash them at some point and we should certainly work to
avoid introducing new ones.

We're about to remove the offending clk_*() functions from the driver,
as they are untested anyway. The hardware the driver was developed for
uses a hardcoded clock rate in the driver anyway, as it cannot be
retrieved from clock tree. As soon as there is hardware available that
will work with the clock tree, we can add those functions back.

Sorry for the noise,
Marc

I get those errors because those patches are in the akpm tree which is
merged after everything else ...

One possibility is to put those changes in another (stable) tree and
merge that into the net-next tree (and any other tree that needs it).

This particular driver don't use the clk framework at the moment. I put 
that lines about clk to try to be generic as possibile, but I see that I 
made a mistake: I'm sorry. An alternative solution to HAVE_CLK 
dependency can be: remove the clk_* lines because actualy nobody use 
them. In the future, if our c_can migrate to clk and our clk framework 
is accepted in the kernel, we can re-add the clk_* lines.

Why would you try to be generic by using an interface currently
only available on certain platforms?

That is how you make drivers non-portable, and not generic.

Then the driver should NEVER have been submitted without the

If what you say is true, I'm extremely pissed off about this now.

This submission was a complete cluster fuck, and it means the person
who submitted this to me didn't test the damn build even.

This driver is tested only on an x86 with AMBA peripherals on PCI. We 
are developing the clk side for this new platform.

Surprised. I am not able to get why this happen. Because we don't have HAVE_CLK defined
for x86_64, then the inline routines like following should come into play:

static inline unsigned long clk_get_rate(struct clk *clk)
{
        return 0;
}


Is there any tricky part for such routines with drivers compiled as modules?

I think the driver is currently used/tested only on ARM only, so what
about adding a HAVE_CLK dependency, until Viresh Kumar's patches are
available in net-next. Later we can remove it.

Well, then Stephen shouldn't get those errors either.

But obviously he did.

But all of this talk about changes existing only in linux-next is
entirely moot.  Because The damn thing MUST build independently inside
of net-next which doesn't have those clock layer changes.

Someone send me a clean fix for net-next now.

Hi Bhupesh,

Please see following patchset from me, that got applied in linux-next

https://lkml.org/lkml/2012/4/24/154

Please check if this patchset is present in your build repo. I believe it should be
there. If it is, then you shouldn't get these errors.

Then x86 will need to provide clock operations, or there needs to
be dummy ones for such platforms.

This isn't rocket science.

So, whether adding a check in Kconfig for HAVE_CLK be a proper solution ?
But that will limit the compilation of this driver for only platforms which are ARM based.

One may need to support this driver on x86 like platforms also..

No, we don't pepper foo.c files with crappy ifdefs.

clk_get/clk_put* variants are usually used by ARM platforms.
Protecting their calls under macro 'CONFIG_HAVE_CLK' should solve the problem.

See [1] for how it is done in c_can_platform.c

Could you possibly add these checks and send a patch for the same?
It should be fairly simple.

Hi all,

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

ERROR: "clk_get_rate" [drivers/net/can/c_can/c_can_pci.ko] undefined!
ERROR: "clk_get" [drivers/net/can/c_can/c_can_pci.ko] undefined!
ERROR: "clk_put" [drivers/net/can/c_can/c_can_pci.ko] undefined!

Caused by commit 5b92da0443c2 ("c_can_pci: generic module for C_CAN/D_CAN
on PCI").  Maybe a missing Kconfig dependency/select?

I have used the net-next tree from next-20120619 for today.

Looks correct, and I'll resolve this the next time I pull

Hi all,

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

drivers/net/ethernet/ibm/ehea/ehea_main.c: In function 'write_swqe2_data':
drivers/net/ethernet/ibm/ehea/ehea_main.c:1692: error: implicit declaration of function 'frag_size'

Presumably caused by commit 9e903e085262 ("net: add skb frag size
accessors").  I guess it should have been "skb_frag_size()".
