[strongSwan-dev] installing route in table 220 is random

[pothuganti sridhar]

Hi,

I am using strongswan 5.3.0 as hub in "hub and spoke" topology. In the HUB
I am configuring "leftsubnet" as "0.0.0.0/0".

When leftsubnet is "0.0.0.0/0", installation of route is not happening
always. I have debugged this issue, and found a variable is being used
uninitialized causing this issue.

Following is the fix.

diff --git a/src/libhydra/plugins/kernel_pfkey/kernel_pfkey_ipsec.c
b/src/libhydra/plugins/kernel_pfkey/kernel_pfkey_ipsec.c
index 3b32ba5..2e91ec4 100644
--- a/src/libhydra/plugins/kernel_pfkey/kernel_pfkey_ipsec.c
+++ b/src/libhydra/plugins/kernel_pfkey/kernel_pfkey_ipsec.c

-       bool is_virtual;

        if
(hydra->kernel_interface->get_address_by_ts(hydra->kernel_interface,

in->dst_ts, &host, &is_virtual) != SUCCESS)

What is the best way to contribute to the strongswan code, if we made any
fixes.

Thanks,
Sridhar
