+Subject: [PATCH] stroke: Increase stroke buffer size to 8k
+
+Complicated connections can have lots of arguments
+for the ike= and esp= directives in the ipsec.conf
+configuration file. strongSwan wouldn't import those
+because the size of the message that is send from
+stroke to charon exceeded the limit of 4k.
+
+This patch increases the size of the buffer that
+can be passed to charon to 8k which should be enough
+even for connections with longer configurations.
