proot info: vpid 1: terminated with signal 9 #142

Closed qoheniac closed 3 years ago

qoheniac commented 3 years ago

I tried to install a dirstro using proot-distro which failed because

proot --link2symlink tar -C /data/data/com.termux/files/usr/var/lib/proot-distro/installed-rootfs/alpine --warning=no-unknown-keyword --delay-directory-restore --preserve-permissions --strip=0 -xf /data/data/com.termux/files/usr/var/lib/proot-distro/dlcache/alpine-minirootfs-3.12.0-armv7.tar.gz --exclude=dev

terminates with signal 9. See also here

  1. Does just running proot tar cause this error?
  2. Please run failing command with -v 9 argument (between proot and tar) and post output

Ok, I'll also need output from:

  1. PROOT_NO_SECCOMP=1 proot -v 9 tar
  2. strace tar

(tar without arguments usually prints help but on your device that was enough to trigger crash, while with different signal it probably has similar cause)

Looks like strace also crashes tar which means that just breaking on syscall is enough to clobber tracee registers.

This means that kernel on your device is faulty and proot cannot work on it (proot like strace breaks on syscall entry/exit but in addition to that it also modifies registers/writes memory, yet without modification registers got clobbered)

This is similar to #46 (which also couldn't be fixed on proot side but in that case there eventually was system update that fixed issue)
