Package: systemd Version: 232-25+deb9u1 Severity: important Dear Maintainer,
systemd is segfaulting in libsystemd-shared when combined with heimdal(heimdal-clients and libpam-heimdal) due of symbol collisions. >From `dmesq` when a user is logging in: ``` [ 4.695291] (systemd)[1059]: segfault at 7f711ea16b8e ip 00007f7123d107f8 sp 00007ffd36ff05f0 error 7 in libsystemd-shared-232.so[7f7123c02000+192000] ``` This has been fixed upstream for future releases: * https://github.com/systemd/systemd/issues/6624 * https://github.com/systemd/systemd/pull/6669 Since the potential for collisions is high I backported their patch to apply to strech as well: ``` diff -Nru systemd-232/debian/changelog systemd-232/debian/changelog --- systemd-232/debian/changelog 2017-07-05 22:31:25.000000000 +0200 +++ systemd-232/debian/changelog 2017-08-29 14:54:14.000000000 +0200 @@ -1,3 +1,10 @@ +systemd (232-25+deb9u1.1) UNRELEASED; urgency=medium + + * Non-maintainer upload. + * Prevent symbol collisions with other programs and libraries. + + -- Johan Carlquist <jo...@su.se> Tue, 29 Aug 2017 14:54:14 +0200 + systemd (232-25+deb9u1) stretch; urgency=medium [ Dimitri John Ledkov ] diff -Nru systemd-232/debian/patches/libsystemd-shared-version-script.patch systemd-232/debian/patches/libsystemd-shared-version-script.patch --- systemd-232/debian/patches/libsystemd-shared-version-script.patch 1970-01-01 01:00:00.000000000 +0100 +++ systemd-232/debian/patches/libsystemd-shared-version-script.patch 2017-08-29 14:54:06.000000000 +0200 @@ -0,0 +1,21 @@ +Index: systemd-232/Makefile.am +=================================================================== +--- systemd-232.orig/Makefile.am ++++ systemd-232/Makefile.am +@@ -1121,6 +1121,8 @@ libsystemd_shared_la_LIBADD = \ + + libsystemd_shared_la_LDFLAGS = \ + $(AM_LDFLAGS) \ ++ -shared \ ++ -Wl,--version-script=$(top_srcdir)/src/shared/libshared.sym \ + -release $(PACKAGE_VERSION) + + +Index: systemd-232/src/shared/libshared.sym +=================================================================== +--- /dev/null ++++ systemd-232/src/shared/libshared.sym +@@ -0,0 +1,3 @@ ++SD_SHARED { ++ global: *; ++}; diff -Nru systemd-232/debian/patches/series systemd-232/debian/patches/series --- systemd-232/debian/patches/series 2017-07-05 22:31:25.000000000 +0200 +++ systemd-232/debian/patches/series 2017-08-29 14:52:37.000000000 +0200 @@ -97,3 +97,4 @@ debian/Let-graphical-session-pre.target-be-manually-started.patch debian/Add-env-variable-for-machine-ID-path.patch cryptsetup-generator-run-cryptsetup-service-before-swap-u.patch +libsystemd-shared-version-script.patch ``` Before patch: ``` # readelf --syms /lib/systemd/libsystemd-shared-232.so | grep parse_time 546: 0000000000110430 2646 FUNC GLOBAL DEFAULT 12 parse_timestamp 1454: 000000000010e4d0 828 FUNC GLOBAL DEFAULT 12 parse_time ``` After patch: ``` # readelf --syms /lib/systemd/libsystemd-shared-232.so | grep parse_time 546: 00000000001104d0 2646 FUNC GLOBAL DEFAULT 12 parse_timestamp@@SD_SHARED 1456: 000000000010e570 828 FUNC GLOBAL DEFAULT 12 parse_time@@SD_SHARED ``` (and no segfault) The patch works just fine on my machine and I hope it could be merged in to stretch-updates. -- jocar -- Package-specific info: -- System Information: Debian Release: 9.1 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-3-amd64 (SMP w/8 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to en_US.UTF-8), LANGUAGE=en_GB:en (charmap=UTF-8) (ignored: LC_ALL set to en_US.UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages systemd depends on: ii adduser 3.115 ii libacl1 2.2.52-3+b1 ii libapparmor1 2.11.0-3 ii libaudit1 1:2.6.7-2 ii libblkid1 2.29.2-1 ii libc6 2.24-11+deb9u1 ii libcap2 1:2.25-1 ii libcryptsetup4 2:1.7.3-4 ii libgcrypt20 1.7.6-2+deb9u2 ii libgpg-error0 1.26-2 ii libidn11 1.33-1 ii libip4tc0 1.6.0+snapshot20161117-6 ii libkmod2 23-2 ii liblz4-1 0.0~r131-2+b1 ii liblzma5 5.2.2-1.2+b1 ii libmount1 2.29.2-1 ii libpam0g 1.1.8-3.6 ii libseccomp2 2.3.1-2.1 ii libselinux1 2.6-3+b1 ii libsystemd0 232-25+deb9u1 ii mount 2.29.2-1 ii procps 2:3.3.12-3 ii util-linux 2.29.2-1 Versions of packages systemd recommends: ii dbus 1.10.18-1 ii libpam-systemd 232-25+deb9u1 Versions of packages systemd suggests: pn policykit-1 <none> pn systemd-container <none> pn systemd-ui <none> Versions of packages systemd is related to: pn dracut <none> ii initramfs-tools 0.130 ii udev 232-25+deb9u1 -- no debconf information
