Subject: [PATCH 05/10] Fix pointer arithmetic for VRRP packet
|
||
|
|
|
||
|
|
When using IPSEC AH authentication, the pointer arithmetic used to get
|
||
|
|
the location of the VRRP packet is incorrect. The address of the IPSEC
|
||
|
|
header must be cast as (char *) in order to get correct address of the
|
||
|
|
VRRP packet. Without this patch, vrrp_in_chk() will fail to verify
|
||
|
|
incoming VRRP packets when IPSEC AH is enabled.
