Testing the rebuilding of openafs for the possible-not-SRU (but at least
is resulting in a lot of polishing for Noble :), because openafs tools
is FTBFS in Noble for other causes [1] ), getting the list of binaries
(not only shared libraries):
for d in $(apt-cache rdepends libroken19-heimdal | cut -d':' -f2 |
xargs); do for b in $(apt-file list ${d} | grep bin | cut -d' ' -f2); do
objdump -T ${b}| grep ROKEN | grep strlc && echo ${b} && echo ${d} &&
apt-cache show ${d} | grep ^Source ; done; done
So, needed action:
* those have to be added to the Breaks.
* hitting an unmet dependencies when installing openafs-krb5, because the
Depends: ${shlibs:Depends}, ${misc:Depends} is converted on Depends:
libroken19-heimdal (= 1.8.10-1ubuntu2.1) but that version number is from
openafs version, not from heimdal: need to check if that comes from the
following change in symbols file (it looks like it, to me):
- libroken.so.19 #PACKAGE# #MINVER#
+ libroken.so.19 #PACKAGE# (= ${binary:Version})

Title:
FTBFS: missing strl* symbols fail the build
Status in heimdal package in Ubuntu:
Fix Released
Status in heimdal source package in Mantic:
Fix Committed
Status in heimdal source package in Noble:
Fix Released
Status in heimdal package in Debian:
New
Bug description:
[ Impact ]
Currently, the build of the heimdal package against glibc 2.38 is not
possible due to
the fact that strlcat and strlcpy were added to glibc in version 2.38 and
heimdal no longer defines its internal version.
We need this fix to build heimdal package successfully.
[ Test plan ]
Build the package in a ppa to check the error is gone and that the
package builds successfully.
# Install the package and check it works ok
#0.Prepare a VM or Container. i.e:
# lxc launch ubuntu-daily:mantic Mheimdal
#1. Install heimtools from heimdal-clients
# apt update && apt upgrade -y
# apt install -y heimdal-clients
#1.1 Check the libraries are installed well
# dpkg -l libroken19-heimdal | grep ii
# dpkg -l libkafs0-heimdal | grep ii
#1.2 Check that the command is not broken (you get a
Usage: : heimtools [--version] [--help] command ..)
# heimtools --help
#2. Install aklog from src:aftools, openafs-krb5 binay. With this, we test
the 2 libraries
that depends on ROKEN symbols we touched in this SRU. A rebuild of
aftools against the
new heimdal package is needed for this to be successfull.
# apt install -y openafs-krb5
#2.1 Check tht the command is not broken (you don't get a
aklog: symbol lookup error: aklog: undefined symbol: rk_strlcat, version
HEIMDAL_ROKEN_1.0)
# aklog --help
[ Where problems could occur ]
I tried to get a complete list of libraries and binaries that use the symbols
affected in this fix
(inside and outside the ones provided by src:hiemdal itself), but, I don't
know if there are other
third-party pieces of software outside the archive that depends on these
libraries.
If that if the case, when executing, the affected binary will no run an a
messge like this can appear:
undefined symbol: rk_strlcat, version HEIMDAL_ROKEN_1.0
Could be a disruption in the way the heimdal suite works? Unlikely, but there
is always room for it.
It should be fine since the symbols, in this case, are available to all
heimdal-dependants libraries in
the build. This case could arise if a mix of heimdal libraries (provided by
two different versions of
src:heimdal) are installed, but this is what the 'Breaks:' that was added in
the d/control wants to avoid.
[ Other Info ]
A rebuild of the openafs package against this new version of the libraries
provided by this heimdal package is needed.
(bug 2046441).
