From: Michael Bykov <m.bykov@gmail.com> To: ALT Linux Sisyphus discussions <sisyphus@lists.altlinux.org> Subject: [sisyphus] electron v 5.0 and user namespaces feature Date: Tue, 22 Oct 2019 01:30:36 +0300 Message-ID: <CAN5SjAD4ysbb_TQ4FJGCOXUU8TmLzrYd4XNBUqvVncvXiWoNOg@mail.gmail.com> (raw) Салют, в electron v.5.0 добавили запуск renreder-процесса в sandboxe, для безобасности, чтобы было не хуже, чем в вебе. Но при старте возникает ошибка: $ npm start [27373:1022/003935.785013:FATAL:setuid_sandbox_host.cc(157)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /home/michael/tmp/sindresorhus/node_modules/electron/dist/chrome-sandbox is owned by root and has mode 4755. Отлично, говорят, лечится $ cd node_modules/electron/dist $ sudo chown root chrome-sandbox $ sudo chmod 4755 chrome-sandbox Тут у всех Линуксов все должно работать, но у нас (и в Arch) - опять ошибка $ npm start The setuid sandbox is not running as root. Common causes: * An unprivileged process using ptrace on it, like a debugger. * A parent process set prctl(PR_SET_NO_NEW_PRIVS, ...) Failed to move to new namespace: PID namespaces supported, Network namespace supported, but failed: errno = Operation not permitted Отлично, говорят лечится https://github.com/electron/electron/issues/17972: $ sudo sysctl kernel.unprivileged_userns_clone=1 или https://github.com/jessfraz/dockerfiles/issues/65#issuecomment-266532289: $ echo 'kernel.unprivileged_userns_clone=1' > /etc/sysctl.d/00-local-userns.conf $ service procps restart Но у нас такие штуки не проходят, естественно. sysctl: cannot stat /proc/sys/kernel/unprivileged_userns_clone: No such file or directory И как быть? Вот что они пишут: ------------ Here's an article I found describing the background of why it's not enabled by default: Controlling access to user namespaces and here's how to enable it (from Enable user namespaces in Debian kernel): https://lwn.net/Articles/673597/ http://superuser.com/questions/1094597/enable-user-namespaces-in-debian-kernel ------------- У меня p8 + Сизиф: $ uname -a (git)-[master] Linux asus 4.9.133-std-def-alt0.M80P.1 #1 SMP Mon Oct 15 16:46:38 UTC 2018 x86_64 GNU/Linux Может быть, нужен какой-то более свежий кернел? Может, в p9 это решено уже? Где про эти юзер-неймспейсы у нас в Альте прочитать-узнать? -- М. http://diglossa.org
