Hi J. R.,

You're absolutely right. I tried gcc7. Thx for pointing me to that
patch. I was able to compile with gcc6 however just fine.

somehow I get with v4.1.40 [1] following error with Aufs v20161219 and

Re: aufs3 with 3.12.52 kernel

2017-01-24 Thread Philip Müller

Hi all,

it is much simplier than you think. As on Manjaro we still support linux
3.12 series. I already released patches to make it work. Simply adopt
them. You can find it here [1].

Please get all patches and the aufs tarfile you find in my github project:

aufs3.12.31+-20141215.patch.bz2

Pre-Patch:

aufs312-3.12.45.patch

Patches applied after:

aufs312-3.12.37.patch
aufs312-3.12.45-2.patch

I recommend to apply them like this [2]:

# fix aufs patches
  rm ${srcdir}/aufs3-base.patch
  rm ${srcdir}/aufs3-standalone.patch
  cp -f ${startdir}/aufs3-base.patch ${srcdir}/aufs3-base.patch
  cp -f ${startdir}/aufs3-standalone.patch ${srcdir}/aufs3-standalone.patch
  cd "${srcdir}"
  patch -Np0 -i "${srcdir}/aufs312-3.12.45.patch"

  # add aufs3 support
  patch -Np1 -i "${srcdir}/aufs3.12.31+-${_aufs}.patch"
  patch -Np1 -i "${srcdir}/aufs3-base.patch"
  patch -Np1 -i "${srcdir}/aufs3-kbuild.patch"
  patch -Np1 -i "${srcdir}/aufs3-loopback.patch"
  patch -Np1 -i "${srcdir}/aufs3-mmap.patch"
  patch -Np1 -i "${srcdir}/aufs3-standalone.patch"
  patch -Np1 -i "${srcdir}/tmpfs-idr.patch"
  patch -Np1 -i "${srcdir}/vfs-ino.patch"
  patch -Np2 -i "${srcdir}/aufs312-3.12.37.patch"
  patch -Np1 -i "${srcdir}/aufs312-3.12.45-2.patch"

Good luck, Philip

aufs4 and 4.3-rc1

2015-09-13 Thread Philip Müller

Hi all,

seems more is "broken" with aufs4 and the latest kernel 4.3 series.
After editing some caveats I saw right away seems I got stuck in the
middle. So this is just a headsup I found so far:

  # fix aufs4
  sed -i -e
's|inode_sb_list_lock|blockdev_superblock->s_inode_list_lock|g'
"${srcdir}/aufs4.x-rcN-${_aufs}.patch"
  sed -i -e 's|+extern spinlock_t
blockdev_superblock->s_inode_list_lock;|+|g'
"${srcdir}/aufs4.x-rcN-${_aufs}.patch"

https://github.com/torvalds/linux/commit/74278da9f70d84d715601fe794567a6d2bfdf078

However I ran into following error after all:

fs/aufs/super.c: In function 'au_show_brs':
fs/aufs/super.c:109:8: error: void value not ignored as it ought to be
err = seq_printf(seq, "=%s", perm.a);
^
fs/aufs/super.c:114:8: error: void value not ignored as it ought to be
err = seq_putc(seq, ':');
^
scripts/Makefile.build:258: recipe for target 'fs/aufs/super.o' failed

make[1]: *** [fs/aufs] Error 2
Makefile:941: recipe for target 'fs' failed
make: *** [fs] Error 2

For now I'll disable aufs on my end until I find more time to dig in.

 By the commit,
 eee5cc2 2013-11-09 get rid of s_files and files_lock
 the file list in superblock, s_files is totally removed.
 
 But aufs still needs the file list, particularly for re-setting the
 branch attribute from RW to RO.
 After resetting to RO, aufs should return EROFS for write. In order to
 support such case, aufs keeps the late s_files and mark_files_ro()
 approach.

 Here is my almost final plan. - in a few weeks, aufs3.{9,11,13}
 will end before linux-3.17 (or 3.18) is released. - in a few
 months, aufs3.{10,10.x,12,12.x} will end because a few users want
 a longer life of aufs3.10.x. - in other words, when linux-3.18
 (or 3.19) is released, the supported versions will be aufs3.14 -
 aufs3.1[89]. Also I am afraid some of them will have .x
 branch.
 
 Now linux-3.18 is released (and aufs3.18 too). At the end of this
 year, all aufs versions before aufs3.14 will become obsolete and go
 to the unsupport-stage.

  You are too late...
 
 
 - My patch is small and simple (and breaks v3.12.37, but that's
 another topic ;).
 
 Probably it should go to aufs3.12.31+ branch.
 
 
 - Only conservative changes are expected in stable branches,
 maintaining it should not cost too many nerves. OK, the change
 above without introducing a macro for compatibility is a perfect
 counterexample. If requested, I would volunteer in maintaining
 aufs3.12.x compatibility.

Re: [aufs3.2] 20131104 - patched for 3.2.66

2015-01-31 Thread Philip Müller

Hi J.R.,

as of now I've no plan to do so either. When there are issues and I can 
help with some patches I'll do so. As a kernel maintainer I can provide 
those fast. So (@Rene) if something is needed, feel free to ping me on 
issues.

kind regards

 Here is a patch to compile the last released aufs3.2 release with linux=20
 3.2.66.
 Great.
 Although I have not read deeply the patch and I don't have a plan to use
 it, I'd like to say thank you.
 If you have a public release repository or something, please let me
 know. I will add it in http://aufs.sf.net.

Re: aufs3 GIT release

2015-01-16 Thread Philip Müller


Hi J.R.,

as I'm almost build all kernels for Manjaro Linux, I found another issue 
with your aufs316-20150105 release.
Starting with 3.16.7-ckt4 followed new stuff got backported from 
linux319 series:


- move d_rcu from overlapping d_child to overlapping d_alias [1]

You find the needed changes as patch with this mail.

Hello Stephen,

sd...@uw.edu:

I'm trying to get acclimated to the required patching that is somewhat date=
d and out of sync with the current linux release 3.12.35+.   I'm using the =
latest on the REPO of AUFS 3.9, but was wondering if you can comment on pat=

:::

I don't know why you chose aufs3.9. If you are using linux-3.12.35, why
don't you try aufs3.12.31+ branch?

Also I am unsure whether you will meet a problem or not since your kernel
source doesn't seem to be vanilla mainline.

Here is another patching method.
Some people prefers git-pull instead of patch(1). For instance,

$ cd raspberrypi/linux.git
$ git checkout raspberrypi-3.12.35
$ git remote add aufs3-linux 
git://aufs.git.sourceforge.net/gitroot/aufs/aufs3-linux.git
$ git pull aufs3-linux aufs3.12.31+



SO, we=92ll just assume those other headers were removed for a reason.  But=
  it is feeling like perhaps this version of the kernel already had incorpor=
ated some level of aufs.

If your base source really has an old version of aufs and you want to
try latest version of aufs, then merging by git-pull (above) will be
better.
Otherwise, if you do it by patch(1), you will need some manual work I am
afraid.

[linux314] aufs 20140127 broken on 3.14-rc3

Re: Compile error

2013-10-22 Thread Philip Müller

Hi Ed,

there should be no problem at all. I tested the latest aufs with 3.10.15 
and with current 3.10.16.
You can find my scripts in my git-repos:

http://git.manjaro.org/package-sources/core/tree/master/linux310

Here is my patch snippet:

# add aufs3 support
patch -Np1 -i ${srcdir}/aufs3.10-${_aufs}.patch
patch -Np1 -i ${srcdir}/aufs3-base.patch
patch -Np1 -i ${srcdir}/aufs3-kbuild.patch
patch -Np1 -i ${srcdir}/aufs3-loopback.patch
patch -Np1 -i ${srcdir}/aufs3-proc_map.patch
patch -Np1 -i ${srcdir}/aufs3-standalone.patch And config: 
http://git.manjaro.org/package-sources/core/blob/master/linux310/config.aufs 
Creating it as module there seems to be some extra steps done. Archlinux 
uses some patches on their kernel and compile it like this: 
https://aur.archlinux.org/packages/au/aufs3/PKGBUILD Here is the patch 
snippet they use on their kernel: msg 'AUFS3 patches' patch -p1 -i 
${srcdir}/aufs3-base.patch patch -p1 -i 
${srcdir}/aufs3-standalone.patch

Hope this helps.

Phil

Am 23.10.2013 01:00, schrieb Ed W:
 Hi, it's always something stupid that I did when the compile fails, so
 apologies in advance, but...

 Kernel 3.10.15 - NOT compiling aufs as a module.

 compilation terminated.
 make[2]: *** [fs/aufs/module.o] Error 1
 make[1]: *** [fs/aufs] Error 2
 make: *** [fs] Error 2

 I believe I have done:

 - apply ./aufs3-kbuild.patch to your kernel source files.
 - apply ./aufs3-base.patch too.
 - apply ./aufs3-proc_map.patch too,
 - copy ./{Documentation,fs,include/uapi/linux/aufs_type.h} files to your
 kernel source tree.
 - make

 So clarifying this, my aufs_type.h file *is* in include/uapi/linux/
 and not in include/linux/ - is this correct?

 (Note that this kernel also has the grsec patches applied.)


 Any quick hints on what I might have done wrong before I take it all
 apart and look more closely?  I guess it's most likely some other patch
 breaks this..?

 Thanks

 Currently and as far as I know, there is no such patch.
 If I remember correctly, some aufs users have applied grsec patch in the
 past, and I have suggested minor modifications. But the version of grsec
 patch was diffrent from yours I am afraid.
 If I have enough time, I would try grsec by myself and develop another
 patch. But I am busy now to implement another aufs whiteout approach
 which is Al Viro's idea originally.
