[lxc.pm] Subject: [pve-devel] [PATCH v2 container] fix #3313: recover unprivileged bit from old config during pct restore X-BeenThere: pve-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox VE development discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 23 Feb 2021 12:32:15 -0000 since pct defaults to privileged containers, it restores the container as privileged when `--unprivileged 1` is not passed. instead we should check the old configuration and retrieve it from there. this way, when one creates an unprivileged container on GUI, it will be still restored as unprivileged via pct (without having to pass `--unprivileged 1` parameter) Signed-off-by: Oguz Bektas --- v1->v2: * move the $is_root guard * wrap line to make it shorter * shorten comment * use () around defined * also check defined($orig_conf->{unprivileged}) src/PVE/API2/LXC.pm | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/src/PVE/API2/LXC.pm b/src/PVE/API2/LXC.pm index 8ce462f..3d3dbb0 100644 --- a/src/PVE/API2/LXC.pm +++ b/src/PVE/API2/LXC.pm @@ -352,7 +352,7 @@ __PACKAGE__->register_method({ my $orig_mp_param; # only used if $restore if ($restore) { die "can't overwrite running container\n" if PVE::LXC::check_running($vmid); - if ($is_root && $archive ne '-') { + if ($archive ne '-') { my $orig_conf; print "recovering backed-up configuration from '$archive'\n"; ($orig_conf, $orig_mp_param) = PVE::LXC::Create::recover_config($storage_cfg, $archive, $vmid); @@ -361,7 +361,11 @@ __PACKAGE__->register_method({ # causing it to restore the raw lxc entries, among which there may be # 'lxc.idmap' entries.
