Bug 355375 – >=app-crypt/heimdal-1.4: Incompatible change in ABI of libgssapi.so

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Arfrever Frehtes Taifersar Arahesis (RETIRED) 2011-02-17 23:54:34 UTC]

libgssapi.so in >=app-crypt/heimdal-1.4 has changed version from HEIMDAL_GSS_1.0 to HEIMDAL_GSS_2.0 without changing filename and soname (from libgssapi.so.2 to e.g. libgssapi.so.3).

Example problem:
$ svn up
Updating '.' ...
/usr/lib/libgssapi.so.2: version `HEIMDAL_GSS_1.0' not found (required by /usr/lib/libsvn_ra_serf-1.so.0)
svn: Unrecognized URL scheme for '${URL}'

All packages installing binaries linked against libgssapi.so.2 need to be rebuilt. If filename of libgssapi.so was changed, then preserve-libs functionality of Portage 2.2.* would preserve old library and suggest reinstallation of packages, which need to be reinstalled.

Possible solutions:
1. Convince upstream to change filename/soname of libgssapi.so.

@@ -201,1 +201,1 @@
-libgssapi_la_LDFLAGS = -version-info 2:0:0
+libgssapi_la_LDFLAGS = -version-info 3:0:0

2. Add a warning in pkg_postinst().

libroken also has the same problem.  Contacted upstream for both of them.  Let's see how they respond.

My interpretation of changes in lib/roken/version-script.map is that libroken.so doesn't have this problem. Only lib/gssapi/version-script.map changes version:
-HEIMDAL_GSS_1.0 {
+HEIMDAL_GSS_2.0 {

[Comment 3 Eray Aslan 2011-02-18 15:35:09 UTC]

libroken has the same problem in the sense that there are symbol changes in the library without any corresponding version change.  Example:

version 1.3.3:
# scanelf -s rk_cloexec_dir /usr/lib/libroken.so.18
 TYPE   SYM FILE 
ET_DYN  -  /usr/lib/libroken.so.18 

version 1.4.x:
# scanelf -s rk_cloexec_dir lib/roken/.libs/libroken.so.18
 TYPE   SYM FILE 
ET_DYN rk_cloexec_dir lib/roken/.libs/libroken.so.18 

resulting in:

/var/tmp/portage/app-crypt/heimdal-1.4.1_pre20110216/work/heimdal/kdc/.libs/kdc:
relocation error:
/var/tmp/portage/app-crypt/heimdal-1.4.1_pre20110216/work/heimdal/lib/krb5/.libs/libkrb5.so.26:
symbol rk_cloexec_dir, version HEIMDAL_ROKEN_1.0 not defined in file
libroken.so.18 with link time reference

What was the response of upstream?

[Comment 6 Eray Aslan 2011-02-20 14:30:26 UTC]

No response yet.

Heimdal upstream is notoriously bad at this stuff
- they forget to do so version bumps, release headers that c++ compilers reject, etc.

Their every release should be approached with caution.

[Comment 9 Eray Aslan 2011-03-02 10:48:34 UTC]

libgssapi version bumped upstream.  In the tree with heimdal-1.4.1_pre20110301.  FYI.
