Bug#958945: lintian,debhelper: lintian emits missing-dependency-on-libc on auto-generated dbgsym package

And from the build log: Iptables module path: /usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug (from binary) And indeed, the way to determine this value seems to be buggy: $ strings /sbin/iptables | grep '^/.*lib.*/.*tables' /usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug I searched the output of "strings /sbin/iptables" for other, similar paths, but there's just none: $ strings /sbin/iptables | grep 'usr' /usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug $ strings /sbin/iptables | grep 'lib' /lib64/ld-linux-x86-64.so.2 libmnl.so.0 libnftnl.so.11 libxtables.so.12 libc.so.6 __libc_start_main /usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug $ strings /sbin/iptables | grep 'x86' /lib64/ld-linux-x86-64.so.2 /usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug So the main issue here seems upstream's self-written configure script that fails on recent iptables binaries. > Maybe lintian should warn about non-debug stuff in dbgsym packages? > I'll probably later retitle and reassign the bug report to lintian > accordingly — once I've better understood wtf is going on here. I'm convinced now that lintian should emit such a warning. Retitling and reassigning accordingly. This tag should be very likely of severity "error".

The issue actually might be elsewhere and the error issued by Lintian might be correct. I though actually still don't know what happens here, especially not why. >From upstream's (generated) Makefile: linstall: | libipt_NETFLOW.so libip6t_NETFLOW.so @echo " *" install -D libipt_NETFLOW.so $(DESTDIR)$(IPTABLES_MODULES)/libipt_NETFLOW.so install -D libip6t_NETFLOW.so $(DESTDIR)$(IPTABLES_MODULES)/libip6t_NETFLOW.so For some reason this causes the file paths mentioned in the lintian warning to be used: $ make -n DESTDIR=debian/tmp linstall echo " *" install -D libipt_NETFLOW.so debian/tmp/usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug/libipt_NETFLOW.so install -D libip6t_NETFLOW.so debian/tmp/usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug/libip6t_NETFLOW.so $ echo $IPTABLES_MODULES $ So I suspect this is the cause for the then likely correct but kinda misleading lintian warning. Maybe lintian should warn about non-debug stuff in dbgsym packages? I'll probably later retitle and reassign the bug report to lintian accordingly — once I've better understood wtf is going on here.

Bug#958945: lintian,debhelper: lintian emits missing-dependency-on-libc on auto-generated dbgsym package
Package: lintian,debhelper Severity: important Version: debhelper/13 lintian/2.68.0 Hi, while preparing the iptables-netflow/2.5-1 upload lintian emits this packaging error (both with dh compat 11 as well as with level 12): E: iptables-netflow-dkms-dbgsym: missing-dependency-on-libc needed by usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug/libip6t_NETFLOW.so and 1 others Since I can't really influence the automatic debug symbol package, this must be either a false positive in Lintian or a bug in debhelper. Filing against both packages for now. Feel free to reassign as needed. The generated and accused dbgsym-package with still dh compat level 11 looks like this: $ debc iptables-netflow-dkms-dbgsym_2.5-1_amd64.deb new Debian package, version 2.0. size 6264 bytes: control archive=516 bytes. 321 bytes,11 lines control 207 bytes, 2 lines md5sums Package: iptables-netflow-dkms-dbgsym Source: iptables-netflow Version: 2.5-1 Auto-Built-Package: debug-symbols Architecture: amd64 Maintainer: Axel Beckert Installed-Size: 59 Depends: iptables-netflow-dkms (= 2.5-1) Section: debug Priority: optional Description: debug symbols for iptables-netflow-dkms drwxr-xr-x root/root 0 2020-04-27 03:26 ./ drwxr-xr-x root/root 0 2020-04-27 03:26 ./usr/ drwxr-xr-x root/root 0 2020-04-27 03:26 ./usr/lib/ drwxr-xr-x root/root 0 2020-04-27 03:26 ./usr/lib/debug/ drwxr-xr-x root/root 0 2020-04-27 03:26 ./usr/lib/debug/.dwz/ drwxr-xr-x root/root 0 2020-04-27 03:26 ./usr/lib/debug/.dwz/x86_64-linux-gnu/ drwxr-xr-x root/root 0 2020-04-27 03:26 ./usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug/ -rw-r--r-- root/root 23752 2020-04-27 03:26 ./usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug/libip6t_NETFLOW.so -rw-r--r-- root/root 23752 2020-04-27 03:26 ./usr/lib/debug/.dwz/x86_64-linux-gnu/iptables.debug/libipt_NETFLOW.so drwxr-xr-x root/root 0 2020-04-27 03:26 ./usr/share/ drwxr-xr-x root/root 0 2020-04-27 03:26 ./usr/share/doc/ lrwxrwxrwx root/root 0 2020-04-27 03:26 ./usr/share/doc/iptables-netflow-dkms-dbgsym -> iptables-netflow-dkms [... other packages ...] -- System Information: Debian Release: bullseye/sid APT prefers unstable APT policy: (990, 'unstable'), (600, 'testing'), (500, 'unstable-debug'), (500, 'buildd-unstable'), (110, 'experimental'), (1, 'experimental-debug'), (1, 'buildd-experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.5.0-1-amd64 (SMP w/4 CPU cores) Kernel taint flags: TAINT_FIRMWARE_WORKAROUND, TAINT_UNSIGNED_MODULE Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE=C.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) LSM: AppArmor: enabled
