2021-05-15dhcp-server: T3544: fix FileNotFoundError on first invokationChristian Poessinger
The problem of using the move() operation over render() is that render will silently create the directory tree in the background and move() does not. This means that on first boot when /run/dhcp-server does not exist, move will fail with a FileNotFoundError. Instead of using move() we render() the configuration two times, one for validating it via dhcpd -t and the other time to really apply it to the service. The performance impact should be little as the config should still be cached in the system RAM. (cherry picked from commit 1f68b69328c961e450ac70b12f7bf073d70355d7)

2021-05-13dhcp-server: T3544: test newly rendered configuration before restarting daemonChristian Poessinger
The current DHCP server implementation comes with options (see below) which allow the user to pass in any arbitrary option(s) in a verbatim way which will manifest in dhcpd.conf. The options are: * set service dhcp-server global-parameters * set service dhcp-server shared-network-name foo shared-network-parameters * set service dhcp-server shared-network-name foo subnet 192.0.2.0/25 subnet-parameters * set service dhcp-server shared-network-name foo subnet 192.0.2.0/25 static-mapping ff static-mapping-parameters Having an invalid configuration will yield: vyos@vyos# commit [ service dhcp-server ] Configuration file errors encountered - check your options! [[service dhcp-server]] failed (cherry picked from commit 3c754695590b9d9e582c10e6d05c2b628e79262c)

2021-01-03dhcp: T3180: bugfix assignment of sliced ranges to config dictChristian Poessinger
A reference to a dictionary key obtained by a for loop can not be used to update values inside that dictionaries key. You must use the original path to the nested dictionaries key.
2021-01-03dhcp: T3180: bugfix NameError when slicing server rangesChristian Poessinger
Introduced in commit e46def834483e ("dhcp: T3100: re-add range slicing support when exclude addresses are used") by not obeying the move from list to dict and still relying on the old list names variables.
2020-12-06dhcp: T2562: add "listen-address" CLI node for better DHCP relay supportChristian Poessinger
Running ISC DHCP server as backend server for multiple pools served to relay agents requires DHCPd to explicitly listen on give interfaces or a "transit" subnet declaration facing the network where we receive the DHCPREQ messages on. This implements a new "listen-address" CLI node, the given address is validated if it is assigned to the system and upon success, a proper "subnet { }" statement is added into dhcpd.conf
2020-12-04dhcp: T3100: re-add range slicing support when exclude addresses are usedChristian Poessinger
Support was not yet present after the rewrite from commit 84b7ade2 ("dhcp: T3100: migrate server configuration to get_config_dict()")

2020-04-12dhcp-server: T2185: create directories in /run on-demandChristian Poessinger
Commit bc68244 ("dhcp-server: T2185: migrate from SysVinit to systemd") migrated the DHCP subsystem to systemd, necessary directories in the volatile /run directory have not been created.
2020-04-12dhcp-server: T2185: fixup ConditionPathExists variableChristian Poessinger
Commit bc68244 ("dhcp-server: T2185: migrate from SysVinit to systemd") migrated the DHCP subsystem to systemd, but on the test-system there was still the old configuration file present not triggering this condition.

2020-04-12template: T2230: use render to generate templatesThomas Mangin
convert all call to jinja to use template.render
2020-04-09util: T2226: os.system was wrongly converted to runThomas Mangin
os.system does print the ouput of the command, run() does not. A new function called call() does the printing and return the error code.
2020-04-06util: T2226: covert most calls from os.system to utilThomas Mangin
As little change a possible but the function call The behaviour should be totally unchanged.

2019-11-28dhcp-serverr: T1825: replaced DHCP configuration error messagezdc
Previous one DHCP configuration error message does not point that DHCP server work only with primary IP address on interface.
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.

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.

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>---
