Bug ID: 241178
Summary: makefs segfault when manifest include symlinks without
the link keyword
Product: Base System
Version: 12.0-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: b...@freebsd.org
Reporter: sh...@fsfe.org
Created attachment 208226
--> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=208226&action=edit
link type require the link keyword
With a directory d/ containing the following 2 files:
-rw-r--r-- 1 root wheel 14 Oct 10 11:55 hello.txt
lrwxr-xr-x 1 root wheel 9 Oct 10 11:55 world.txt -> hello.txt
using mtree to build a manifest as follow:
mtree -ck mode -p ./d | mtree -C > no-link-kw.makefs-manifest
here is the resulting manifest:
. type=dir mode=0755
./hello.txt type=file mode=0644
./world.txt type=link mode=0755
running makefs as follow lead to segfault:
cd d
makefs -t ffs -o optimization=space -o version=2 ../no-link-kw.img
../no-link-kw.makefs-manifest
Attached is a small fix that ensure makefs will complain about the missing link
keyword when facing a link type node.
