Subject: [PATCH] bgpd: Fix AS_PATH size calculation for long paths
|
||
|
|
|
||
|
|
If you have an AS_PATH with more entries than
|
||
|
|
what can be written into a single AS_SEGMENT_MAX
|
||
|
|
it needs to be broken up. The code that noticed
|
||
|
|
that the AS_PATH needs to be broken up was not
|
||
|
|
correctly calculating the size of the resulting
|
||
|
|
message. This patch addresses this issue.
