In keepalived, ipset is only used when iptables support is
enabled. The configure.ac script is quite convoluted, but one can
clearly see:
AS_IF([test .$enable_iptables != .no],
[
... testing for iptables ...
if test $USE_IPTABLES = Yes; then
dnl ----[Check for ipset libraries]----
SAV_CPPFLAGS="$CPPFLAGS"
CPPFLAGS="$CPPFLAGS $kernelinc"
if test "${enable_libipset}" != no; then
... testing for libipset ...
fi
]
So, the libipset library is only tested and used if iptables is
enabled. This is also visible by the code that shows at the end of the
configure script which features are enabled:
echo "Use iptables : ${USE_IPTABLES}"
if test .$USE_IPTABLES = .Yes; then
echo "Use libipset : ${USE_LIBIPSET}"
fi
Once again, the libipset support only makes sense when iptables is
enabled.
However, the configure.ac script also has some logic to detect if a
--<something>-libipset option is passed while iptables is enabled:
AS_IF([test .$enable_iptables = .no],
AS_IF([test .$enable_libipset != .], [AC_MSG_ERROR([disable-libipset requires vrrp and iptables])])
)
The error message is quite misleading because it is in fact displayed
as soon as a --<something>-libipset is passed not just
--disable-libipset.
In the context of Buildroot, we are always passing a
--<something>-libipset, regardless of whether iptables support is
enabled or not, which makes the build error out:
configure: error: disable-libipset requires vrrp and iptables
This commit fixes that by enclosing the libipset logic inside the
iptables condition. When iptables is not available, we pass
--disable-iptables and that's it, nothing else is needed. When
iptables is available, we pass --enable-iptables *and*
--enable-libipset or --disable-libipset depending on the availability
of libipset.
This has been tested successfully with the following combinations:
- keepalived, without iptables or libipset
- keepalived, with iptables, but without libipset
- keepalived, without iptables, but with libipset. In this case
libipset is obviously not used.
- keepalived, with iptables and with libipset. Both are used. Note
that you will not see the keepalived binary linked with libipset.so
in "readelf -d" because keepalived dlopen()s the libipset.so
library by default.
