Benjamin Drung	0378c101bb	Pass extended attributes (excluding system) to tar2sqfs /bin/ping (from iputils-ping) uses the security capabilities to allow users to use the program: ``` $ getcap /bin/ping /bin/ping cap_net_raw=ep ``` Debian testing/unstable images (variant important) contain security and system attributes: ``` $ mmdebstrap --variant=important bullseye root.tar $ tar --xattrs --xattrs-include='' -vv -tf root.tar \| grep -B 1 '^ ' -rwxr-xr-x 0/0 77432 2021-02-02 18:49 ./bin/ping x: 20 security.capability -- drwxr-sr-x* 0/102 0 2021-05-07 15:10 ./var/log/journal/ x: 44 system.posix_acl_access x: 44 system.posix_acl_default ``` When generating a squashfs image with mmdebstrap 0.7.5-2, these security capabilities are lost. Example for building a squashfs image in a minimal Debian unstable schroot: ``` $ apt install -y mmdebstrap squashfs-tools-ng $ mmdebstrap --variant=important buster root.squashfs $ rdsquashfs -x /bin/ping root.squashfs $ ``` tar2sqfs from squashfs-tools-ng 1.0.4-1 supports encoding extended attributes from the namespace `user`, `trusted`, and `security` (see `include/sqfs/xattr.h`). GNU tar (version 1.34) supports these three namespaces plus the namespace `system`. Passing extended attributes from the `system` namespace to tar2sqfs will produce an error: ``` ERROR: squashfs does not support xattr prefix of system.posix_acl_default ``` So pass the extended attributes to tar2sqfs, but exclude the `system` namespace. Then ping will keep its security attributes: ``` $ rdsquashfs -x /bin/ping root.squashfs security.capability=0x0100000200200000000000000000000000000000 ``` Closes: #988100 Signed-off-by: Benjamin Drung <benjamin.drung@ionos.com>	2021-05-17 21:43:10 +02:00

Konstantin Demin	ccd4b5c163	gpg: handle ASCII-armored keyrings as well gpg command "--list-keys" requires input files to be passed with option "--keyring" and each file must match type "public keyring v4" while gpg command "--show-keys" doesn't require extra options and handles also ASCII-armored public keyrings as well.

Johannes Schauer Marin Rodrigues	5a3d1ab5c4	Rework /dev, /sys, /proc mounting - assume all entries in @devfiles to be in /dev - allow for /dev, /sys and /proc not to exist in the target and print warning - allow for /dev entries as well as /sys and /proc not to exist on the outside - simplify umount by storing special options in @umountopts - remove superfluous checks for root and unshare mode - make sure /dev entries are less than 100 chars in size for tar	2021-03-08 08:04:35 +01:00

Benjamin Drung	043ab3bbf0	tarfilter: Compile prefix pattern only once According to Debian bug #978742, mmtarfilter has a slow performance with many path exclusions. The execution can be speed up if the regular expression is only compiled once instead of every time in the hot loop.
