*: make consistent & update GPLv2 file headers The FSF's address changed, and we had a mixture of comment styles for the GPL file header. (The style with * at the beginning won out with 580 to 141 in existing files.)

enum filter_type pim_access_list_apply(struct access_list *access, const struct in_addr *source,
const struct in_addr *group);
pimd,yang: Extend multicast boundary functionality Add new interface command ip multicast boundary ACCESSLIST4_NAME. This allows filtering on both source and group using the extended access-list syntax vs. group-only as with the existing "ip multicast boundary oil" command, which uses prefix-lists. If both are configured, the prefix- list is evaluated first. The default behavior for both prefix-lists and access-lists remains "deny", so the prefix-list must have a terminating "permit" statement in order to also evaluate against the access-list. The following example denies groups in range 229.1.1.0/24 and groups in range 232.1.1.0/24 with source 10.0.20.2: ! ip prefix-list pim-oil-plist seq 10 deny 229.1.1.0/24 ip prefix-list pim-oil-plist seq 20 permit any ! access-list pim-acl seq 10 deny ip host 10.0.20.2 232.1.1.0 0.0.0.255 access-list pim-acl seq 20 permit ip any any ! interface r1-eth0 ip address 10.0.20.1/24 ip igmp ip pim ip multicast boundary oil pim-oil-plist ip multicast boundary pim-acl !
