[Solved] Gentoo in chroot - Temporary failure in name resol.

Post by mvasi90 » Mon Aug 16, 2021 6:29 pm

Hello everyone,

I'm new user in Gentoo, I come from ArchLinux. (ArchLinux user since 2013).
On all my devices I have ArchLinux (including the smartphone), and I am considering moving to Gentoo.
I love Gentoo.

My first try is to use this distribution on Android device.
I have downloaded the stage3 tarball and followed the steps in the handbook.

The

Code: Select all

emerge-webrsync

works, but the next step

Code: Select all

emerge --ask --verbose --update --deep --newuse @world

doesn't work.
The error is:

Code: Select all

mvasi90,

Welcome to Gentoo. I suspect you have a typo in make.conf.
Maybe

Code: Select all

emerge --info

will show it?
Post the output.

As a workaround, try

Code: Select all

GENTOO_MIRRORS=""  emerge --ask --verbose --update --deep --newuse @world

Don't make a habit of that. It bypasses the Gentoo mirror system and fetches directly from the source projects own repos.
Its generally a badthing but for testing, its worth trying.

Regards,

NeddySeagoon

Computer users fall into two groups:-
those that do backups
those that have never had a hard drive fail.

mvasi90,

Tell us a bit about the hardware and how yon managed to chroot on an arm64 system.
What is the underlying system you are chrootinig from?

As its an arm system it belongs in Gentoo an ARM. I'll move the topic now.

Regards,

NeddySeagoon

Computer users fall into two groups:-
those that do backups
those that have never had a hard drive fail.

Note:The script is the same as I use for ArchLinux chroot in the same device.
It can be improved, for example changing the "ce" function and calling it like: mount ... || die "error msg" err_code.
But for now it's okay.

ArchLinux works without these lines. I put them to fix some problems in Gentoo.

Code: Select all

export HISTFILE=/dev/null
export SHELL=/usr/bin/bash

Some important information.
This is the real output of the emerge command:

Code: Select all

Total: 22 packages (16 upgrades, 1 new, 5 reinstalls), Size of downloads: 51334 KiB
Conflict: 1 block

Would you like to merge these packages? [Yes/No]
Sorry, response '               ' not understood. [Yes/No]

>>> Verifying ebuild manifests

>>> Running pre-merge checks for dev-lang/python-3.9.6_p1
Unable to unshare: EINVAL (for FEATURES="pid-sandbox")

>>> Running pre-merge checks for sys-fs/eudev-3.2.10-r1

As you can see, on every package appears the warning: "Unable to unshare: EINVAL..."
To solve that, I'm using this:

Code: Select all

export FEATURES="-ipc-sandbox -network-sandbox -pid-sandbox"

But I don't like it. I am paranoid and everything related to security should not be disabled.

Kernel and Kernel config options:

Code: Select all

The Portage ebuild checks for the namespaces below:

Code: Select all

       local CONFIG_CHECK="~IPC_NS ~PID_NS ~NET_NS ~UTS_NS"

So why are CONFIG_UTS_NS and CONFIG_PID_NS disabled? CONFIG_IPC_NS doesn't even seem to exist? Maybe because 4.14 is quite old....

For now I cannot update Android. The device came with the update option disabled and the bootloader unlocked.
I'll update it when official LineageOS for this model comes out, because I don't have enough time to port it to this device. (Kernel sources are not published).

dmesg shows nothing when emerge is running. No SELinux, iptables or any other log.

The iptables default policy is DROP for INPUT, OUTPUT and FORWARD chains because I'm using a whitelist mode. I changed it to ALLOW but emerge keeps giving the same error.

I have added the rule "iptables -A OUTPUT -j LOG --log-uid", but nothins appears in "dmesg -w" (related to emerge).

If ArchLinux works with the same configuration, I think it is Gentoo problem.
I also tested the emerge with --debug and --verbose param, but no relevant information about the error.

Solved.

The user portage should be added to the aid_inet group.
The aid_inet group (the group name is not important) should be added with the gid 3003 (Android inet).

Code: Select all

groupadd -g 3003 -r aid_inet
usermod -aG aid_inet portage
usermod -aG aid_inet root

Note: There are more groups to be added:

Code: Select all

grep aid /etc/group

aid_net_bt_admin:x:3001:root
aid_net_bt:x:3002:root
aid_inet:x:3003:root,avahi,user
aid_inet_raw:x:3004:root,avahi
aid_inet_admin:x:3005:root,avahi                                                                                                                           aid_sdcard_rw:x:1015:user
aid_media_rw:x:1023:user,root
aid_everybody:x:9997:user

aid_net_bt and aid_net_bt_admin for bluetooth permissions
aid_inet for internet access
aid_inet_raw for network raw access
aid_media_rw for storage permission (/sdcard)
aid_everybody for access some files
