Bug ID: 231072
Summary: Mtree calculates checksum wrong when verifying a
specification against a directory.
Product: Base System
Version: 11.2-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
https://www.freebsd.org/doc/handbook/security-intro.html the mtree(8) example
at section 13.2.6 Binary Verification is not working correctly. The output from
the verification step is empty as expected but the checksum printed differs
from the one calculated at the specification creation step.
# mtree -s 3483151339707503 -c -K cksum,sha256digest -p /bin >
/root/.bin_chksum_mtree
mtree: /bin checksum: 1817933408
# mtree -s 3483151339707503 -p /bin < /root/.bin_chksum_mtree >>
/root/.bin_chksum_output
mtree: /bin checksum: 1510745247
# file .bin_chksum_output
.bin_chksum_output: empty
The system I'm using is:
# uname -a
FreeBSD firewall 11.2-RELEASE-p2 FreeBSD 11.2-RELEASE-p2 #3 r338073: Mon Aug 20
16:44:39 EEST 2018 root@firewall:/usr/obj/usr/src/sys/GENERIC amd64
Filesystems used are ZFS all around except tmpfs /tmp and /var/run.
