 Posted: Sat Jan 26, 2019 6:48 am Post subject: Problem with chrooted emerge [SOLVED] |
 |
|
Hello,
I am building a system for an embedded cross-target (arm64 on x86_64 host). I have mostly followed guides from here and here. I have managed to cross-compile most of base system, I have installed qemu and its binfmt handler. I can chroot there, and almost everything works except emerge.
| Code: |
alias emerge-chroot='ROOT=/ CBUILD=aarch64-unknown-linux-gnu HOSTCC=aarch64-unknown-linux-gnu emerge'
# emerge-chroot htop
Calculating dependencies... done!
>>> Verifying ebuild manifests
>>> Emerging (1 of 1) sys-process/htop-2.2.0::gentoo

* does not exist: '/tmp/portage/sys-process/htop-2.2.0'
>>> Failed to emerge sys-process/htop-2.2.0
* Messages for package sys-process/htop-2.2.0:

"htop" is just for example, any package fails with the same error. As I understand, some build step silently fails and emerge is unable to find build output directory. I am pretty sure that the problem is not with the "/tmp/portage" directory itself, it's in place, and emerge is creating it if deleted. May be it is related to qemu message "qemu: qemu_thread_create: Invalid argument". However I am unable to reproduce it on any other program in this environment, and have found nothing useful about it. I also tried to manually build some downloaded source packages via configure/make in this environment. They are built and work without problems.
emerge.log:
| Code: |
1548483902: Started emerge on: Jan 26, 2019 06:25:02

So the question is - how to troubleshoot emerge in general? How to understand which exactly build step leaded to "die_hooks" phase and why? I tried to use --debug option but it only dumps dependency graph related information, nothing about what is done in ebuild.

Some update. Half an hour in the morning is more productive than half a night. I found that running ebuild command manually works and the package is successfully setup, configured, compiled and installed. The directory in /tmp/portage is created without problems. The failing step is "clean" (however it does it job and directory is deleted). Still thinking how to troubleshoot it.
| Code: |
# ROOT=/ CBUILD=aarch64-unknown-linux-gnu HOSTCC=aarch64-unknown-linux-gnu ebuild htop-2.2.0.ebuild clean
qemu: qemu_thread_create: Invalid argument
* The ebuild phase 'die_hooks' has been aborted since PORTAGE_BUILDDIR
* does not exist: '/tmp/portage/sys-process/htop-2.2.0'

Adding FEATURES="noclean" does not help with emerge for some reason.
Qemu message appears for other steps from time to time but seems does not affect them. |

This looks important. PORTAGE_BUILDDIR should normally be /var/tmp/portage - check that it exists and is owned by portage.
(at least on x86, I am not so sure about the arm64 qemu environment) |

In make.conf I have:
PORTAGE_TMPDIR=${ROOT}tmp/
which was set by crossdev.
So it ends up in /tmp/portage which is accessible, and as I said, it works with ebuild.
I there any way to see at least which ebuild commands are being executed by emerge? |

I missed that, sorry! And now I realize that probably PORTAGE_TMPDIR=/tmp and PORTAGE_BUILDDIR=/tmp/portage.
Could you post the output of emerge --info? It might help to bring some other ideas. |

vagran,
What are the permissions on the PORTAGE_TMPDIR target?
Portage itself starts as root then drops to portage:portage for all the phases it can. (ebuild won't do that)
Check that portage can read and write PORTAGE_TMPDIR as the portage user.

vagran,
Is that --info from inside your aarch64 chroot?
If so, qemu emulates an arm64 CPU, so
CBUILD="x86_64-pc-linux-gnu" is incorrect.
PKGDIR="/usr/aarch64-unknown-linux-gnu/packages/" looks odd. That's at /usr/aarch64-unknown-linux-gnu/usr/aarch64-unknown-linux-gnu/packages/ from your real amd64 root.
You need a different make.conf when you chroot into a qemu arm64 emulated environment.
Compare https://paste.pound-python.org/show/o1yME8epzb0TMSwC2gBd/ and https://paste.pound-python.org/show/kUUyb5ArI0U7ovsKW54J/
That my two. I have a make.conf symlink to manage to choose between them.
Your gcc version is missing in
| Code: | | Portage 2.3.58 (python 3.6.6-final-0, default/linux/arm64/17.0, gcc-8.2.0, unavailable, 4.14.83-gentoo aarch64) |
I set up the chroot with
| Code: | #!/bin/bash
# run this script to prepare the arm64 chroot
# for QEMU building
# start the binfmt service on the host
# ignore the error if its already running
/etc/init.d/binfmt start
# tell the kernel about aarch64 - the above service should do it
# but it seems not to, sometimes.
echo ':aarch64:M::\x7fELF\x02\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\xb7:\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xfe\xff\xff:/usr/bin/qemu-aarch64:' > /proc/sys/fs/binfmt_misc/register
cd /usr/aarch64-unknown-linux-gnu/
# set the right make.conf for QEMU
rm make.conf
ln -s make.conf_qemu make.conf
mount --bind /usr/portage usr/portage
mount --bind /usr/portage/distfiles var/cache/distfiles
# not /usr/portage/packages as they are for the host!
mount --bind /proc proc
mount --bind /sys sys
mount --bind /dev dev
mount --bind /dev/pts dev/pts
# must be after the bind mount of dev
mount tmpfs -t tmpfs -o rw,nosuid,nodev,noexec dev/shm
# don't actually do the chroot |
-- edit -- you get extra points for spotting the bug in that script

Yes.
| Quote: | | CBUILD="x86_64-pc-linux-gnu" is incorrect. |
I followed instructions and run emerge as
| Code: | | ROOT=/ CBUILD=aarch64-unknown-linux-gnu HOSTCC=aarch64-unknown-linux-gnu ebuild |
when running in chroot (actually made an alias "emerge-chroot" as in this guide. So I suppose CBUILD is overriden and config swapping is not really needed.
The same story for packages directory, it depends on ROOT.
Actually I have run "emerge --info" without these environment variables, so the compiler is displayed wrong. Here is the correct version:
| Code: | # emerge-chroot --info
Portage 2.3.58 (python 3.6.6-final-0, default/linux/arm64/17.0, gcc-8.2.0, glibc-2.28-r5, 4.14.83-gentoo aarch64)

For some reason it still incorrectly shows packages and temporal path, looks like "--info" ignores part of environment, but when running merge, the temporal path is /tmp/portage as it should be according to my make.conf (based on what was generated by crossdev):
| Code: | # cat /etc/portage/make.conf
# Note: profile variables are set/overridden in profile/ files:
# etc/portage/profile/use.force (overrides kernel_* USE variables)
# etc/portage/profile/make.defaults (overrides ARCH, KERNEL, ELIBC variables)
CHOST=aarch64-unknown-linux-gnu
CBUILD=x86_64-pc-linux-gnu
HOSTCC=${CBUILD}-gcc
ROOT=/usr/${CHOST}/
ACCEPT_KEYWORDS="${ARCH} ~${ARCH}"
USE="${ARCH} -pam -acl"

PKGDIR=${ROOT}packages/
PORTAGE_TMPDIR=${ROOT}tmp/
PKG_CONFIG_PATH="${ROOT}usr/lib/pkgconfig/"

|
Now I have tried to set "PKGDIR=/packages/" in this config, but it did not affect the problem. If I correctly understand, this only used if building binary packages which is not what I am doing in chroot. |

vagran,
I use this guide but I'm biased. :)
Once in the qemu chroot, emerge will work as normal, but as I say, you need a native make.conf when you use qemu and a cross make.conf when you cross compile.

And what about question about emerge troubleshooting? Is it really not possible to get fail reason in easy way?
What I am currently doing is debugging it in PDB to get at least exact phase it failed. |

vagran,
| Code: | | qemu: qemu_thread_create: Invalid argument |
is the first error.
It looks like qemu isn't happy.
I'm using a statically built qemu-9999 because some syscalls are not yet implemented. The live code is as good as it gets.
A few syscall errors can be ignored but one or two break portage.

I have installed qemu-9999, unfortunately it didn't help. I also tried to change make.conf to not depend on environment variables, did not help as well.
What I have so far:
- The problem is in "clean" phase called by emerge. Checked this in debugger. The same effect is also achieved by running it manually as "ROOT=/ CBUILD=aarch64-unknown-linux-gnu HOSTCC=aarch64-unknown-linux-gnu ebuild htop-2.2.0.ebuild clean".
- Message about missing PORTAGE_BUILDDIR is normal behaviour in this case. It occurs exactly in case if initial clean fails because the build directory is not yet created, but "die_hooks" phase expects it exists. It's some design flaw of the portage system. It even has corresponding comment in the code:

- The phase implementation is call of "/bin/bash -c /usr/lib/portage/python3.6/ebuild.sh clean" command with proper environment set. And this command works well, the script returns zero exit code at the end. But for some reason python spawner thinks it is failed (I've seen some strange code -6 while debugged). |

vagran,
My arm64 build root is about a year out of date. I'll update it from my BINHOST and see if I can reproduce this.
Eww ... - dev-util/mdds-9999::gentoo (masked by: EAPI 7) its older than I thought.

So far I found that child process ("bash -c /usr/lib/portage/python3.6/ebuild.sh clean") returns this result to ebuild:
posix.waitid_result(si_pid=21843, si_uid=0, si_signo=17, si_status=6, si_code=2)
It basically means it was kill by SIGABRT. As found before, the script ebuild.sh itself completes successfully so it probably happens after the script is executed. I suspect qemu crash. Will proceed with obtaining core dump. |

And seems that's really qemu problem:
| Code: | # file tmp/core-python3.6m-6-1548588223
tmp/core-python3.6m-6-1548588223: ELF 64-bit LSB core file, x86-64, version 1 (SYSV), SVR4-style, from '/usr/bin/qemu-aarch64 /usr/bin/python3.6m /usr/lib/portage/python3.6/pid-ns-ini', real uid: 0, effective uid: 0, real gid: 0, effective gid: 0, execfn: '/usr/bin/python3.6m', platform: 'x86_64' |
As I understand, executable is not bash because ebuild spawns it by fork()/exec() so it inherits parent command line. The trace corresponds to the error message seen before.

This package list doesn't seem to be really related...

The problem is with pthread_create in this line. It returns EINVAL which probably caused by invalid attributes. The attributes are properly initialised earlier and pthread_attr_setdetachstate() was called with PTHREAD_CREATE_DETACHED. I do not really have ideas what to do next. The only guess is that it is somehow related to static linkage and libpthread was somehow broken during this process. I will also try to research live debugging possibility of this place in the qemu code. |

vagran,
Well, my chroot used to work until I updated those packages.
With a broken portage, its a bit difficult to downgrade portage to test :)
-- Edit --
However, once you get | Code: | >>> sys-apps/portage-2.3.51-r1 merged.
Unsupported ioctl: cmd=0x5441 |
the qemu chroot works again.
The Unsupported ioctl: cmd=0x5441 is new and I got an Unsupported syscall 285?
Its not in the build logs.
Later portage versions may work too but portage-2.3.58 does not.

That helped, thanks!
I also checked version 2.3.57 - broken as well. 2.3.51-r1 is the last one working.
I think its subprocess spawning manner somehow triggered the bug in qemu or libpthread. Probably this should be reported somewhere. |

vagran,
File a bug at bugs.gentoo.org.
You have a lot more detail than me. I'm not convinced its a portage bug bet if not, qemu will need a test case to be able to fix it.
The portage team will report it upstream if that's what it needs.

<mrueg> NeddySeagoon: my suggestion is to play with enabling disabling the sandboxes
<mrueg> start with FEATURES="-pid-sandbox"
<NeddySeagoon> mrueg: Ill try it, Thanks |

I also have another problem also for this chrooted configuration. If I attempt to install some python packages, the following error occurs:
(for emerge dev-python/pygments)
| Code: |

Similar error e.g. for dev-util/meson which is systemd dependency. Do you have any idea how to fix this?
EDIT:
FEATURES="-usersandbox" helps. Not sure, may be it is related to the same problem with qemu. Native environment does not have this problem with python packages. |

vagran,
Check the version of sandbox that you have,
| Code: | $ eix sandbox
[I] sys-apps/sandbox
Available versions: 2.12 2.13{tbz2} (~)2.14{tbz2} (~)2.15{tbz2} |
upgrade if needed.
If that fails, turn bits of sandboxing off. Check FEATURES= in
Warning. Sandboxing is a safety feature. Access Violations usually mean that an ebuild is doing something its not supposed to.
It looks like it was trying to open /usr/lib64/python3.6/lib2to3/Grammar3.6.6.final.0.pickle for writing.

Sorry to resurrect, but did a bug in either bugs.gentoo.org or qemu's tracker ever get filed re: the original PTHREAD_CREATE_DETACHED throwing an invalid argument in qemu problem?
Now that portage-2.3.62 has stabled I hit this on all my chroots as well.
