I have been compiling packages for aarch64 in a qemu chroot, this worked very well for quite some time. Now, after upgrade to portage-2.3.55 (from 2.3.50; no other packages upgraded), I cannot emerge anything:
Code:
emerge -av1 --debug nano
...
>>> Emerging (1 of 1) app-editors/nano-3.2::gentoo
qemu: qemu_thread_create: Invalid argument
+ __dyn_clean
+ '[' -z /var/tmp/portage/app-editors/nano-3.2 ']'
+ '[' '!' -d /var/tmp/portage/app-editors/nano-3.2 ']'
+ return 0
+ set +x
 * The ebuild phase 'die_hooks' has been aborted since PORTAGE_BUILDDIR
 * does not exist: '/var/tmp/portage/app-editors/nano-3.2'

>>> Failed to emerge app-editors/nano-3.2


I can't reproduce the problem in qemu with system emulation mode, so probably this is user mode specific.

I would like to understand more about this, but I could not find anything about this in google.

I came across the same problem. I don't know why it is happening, but I used the cross compiler to downgraded back and masked the new version in the target environment for now. Point is - you aren't the only one...

I checked the currently stable portage-2.3.51-r1. This problem does not come up.

Upd: with portage-2.3.56 the problem is present.

Same issue here. I have had to mask >=sys-apps/portage-2.3.53 for arm64. Last version that I found that works with a QEMU chroot is 2.3.52-r1.

Can you bisect between those two revisions to find the commit that introduced the incompatibility? That might help track down what qemu-user fails to emulate correctly.

The culprit is the pid-sandbox feature, turned on by default in commit 55a9d4ccc5ac90b454638f9205f8a5d20ca8b47a

With FEATURES="-pid-sandbox" new versions of portage work fine...

Same issue for me, and FEATURES="-pid-sandbox" worked.
Is there a bug on https://bugs.gentoo.org for this? I couldn't find it.
I would suppose that adding FEATURES="-pid-sandbox" to crossdev's default make.conf will be reasonable until it is fixed.
