| 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. |
