2019-10-19dhcp-server: T1745: bugfix corner case on static-assignmentsChristian Poessinger
There was a bug when refactoring this with commits 5848a4d ("dhcp-server: T1707: remove DHCP static-mappings from address pool") and 1182b44 ("dhcp-server: T1707: bugfix on subsequent DHCP exclude addresses") that when a static address assignemnt was using the last IP address from the specified range. This triggered the following error: "DHCP range stop address x must be greater or equal to the range start address y!"
2019-10-03dhcp-server: T1707: remove DHCP static-mappings from address poolChristian Poessinger
Previously when static-mappings have been created the address was still within the DHCP pool resulting in log entries as follows: dhcpd: Dynamic and static leases present for 192.0.2.51 dhcpd: Remove host declaration DMZ_PC2 or remove 192.0.2.51 dhcpd: from the dynamic address pool for DMZ (cherry picked from commit 6f954ab56768af9a07d8a1dc086f54ddefa58da7)
2019-10-03dhcp-server: only import ip_address and ip_network from ipaddress classChristian Poessinger
(cherry picked from commit bdf890cca40157b3f2a2386685e043e0fa220fac)
2019-10-03dhcp-server: T1707: bugfix on subsequent DHCP exclude addressesChristian Poessinger
Moved the code for splicing a DHCP range into its dedicated function as this will later be required again. Having subsequent DHCP exclude addresses e.g. 192.0.2.70 and 192.0.2.71 did not work as the previous algorithm created a range whose start address was after the end address. (cherry picked from commit 0f0f9f2835cf85c1fd3652ec83368528754764cd)
2019-07-18T1440: in IPv4 DHCP, print the subnet rather than a dict dumpDaniil Baturin
when a non-unique subnet is found.
2019-07-04T1435 plus other dhcp/dhcpv6-server enhancementsJernej Jakob
- T1435: dhcp-server: make ip-address optional in static-mapping - remove [REQUIRED] from dhcpv6-server static-mapping identifier and ipv6-address - verify if static-mapping ipv6-address is in subnet - make help and error messages in conf-mode more descriptive - remove regex ^$ anchors (implied in re.fullmatch)

2019-04-10[dhcp] T1330: bugfix for non working wpad urlChristian Poessinger
WPAD url could be configured by CLI but the generated config was not understood by ISC dhcp - caused by infalid if {} statement resulting in a missing "option wpad-url code 252 = text;" block.

subnet-parameters were not added to the resulting configuration.

Move the on commit in a generated dhcpd.conf into the shared-network to fix hostfile-update not working.
2018-09-04dhcp_server.py: bugfix pool assignmentChristian Poessinger
Commit 91c3b8bdd9 ("dhcp_server.py: cleanup") did not only cleanup parts of the code but in addition added support for DHCP failover. That support could lead to an empty pool {} statement if the subnet declaration only had static address assignments but no range at all. ---<snip>--- dhcpd: /etc/dhcp/dhcpd.conf line 70: Pool declaration with no address range. dhcpd: } dhcpd: ^ dhcpd: Pool declarations must always contain at least dhcpd: one range statement. ---</snip>---

2018-08-30dhcp_server.py: rework verify() error messages/error checkingChristian Poessinger
Commit 067a6b1524 ("vyos: package: extend validator by is_subnet_connected()") added a mechanism to probe if a given IPv4/IPv6 address is connected to any interface on the subnet - or is part of this subnet. We now use this call instead of producing more and more biler-plate code!

2018-08-29dhcp_server.py: improve handling of 'dhcpd.leases' fileChristian Poessinger
If there was yet no lease file present, dhcpd refused to start. Lease file is created if required. Ususally this is handeled by the isc-dhcp-server init script but we use our own path (for persistance) of that file.

2018-08-27T778: T782: dhcp-server: XML and Python rewriteChristian Poessinger
This commit changes in addtion the DHCP server config syntax as defined in "T782: Cleanup dhcp-server configuration". Replace boolean parameter from the folowing nodes and make it valueless. This requires a migration script which is tracked with this task * set service dhcp-server shared-network-name <xyz> subnet 172.31.0.0/24 ip-forwarding enable (true|false) * set service dhcp-server shared-network-name <xyz> authoritative (true|false) * set service dhcp-server disabled (true|false) * set service dhcp-server dynamic-dns-update enable (true|fals) * set service dhcp-server hostfile-update (enable|disable) Replace the nested start/stop ip address from "subnet 172.31.0.0/24 start 172.31.0.101 stop 172.31.0.149" to "subnet 172.31.0.0/24 range <foo> start" and "subnet 172.31.0.0/24 range <foo> stop" where foo can be any character or number. In addition the vyatta-cfg-dhcp-server package used it's own init/config file for service startup. This has been migrated to the vanilla Debian files. Copy 'on-dhcp-event.sh' from vyatta-cfg-shcp-server package commit 4749e648bca6.
