* Add support for a DHCP_OPTS parameter.HEADmasterDarren 'Tadgy' Austin2023-06-211-0/+4
| | | | | | | | | | | This commit allows an interface specific DHCP_OPTS parameter to set additional dhcpcd command line options where they may be required on a local network. It is still recommended to use the supported DHCP_* options in preference to this option, but it is being added to aid customisations. Thanks to ljb643 on LQ for the bug report regarding DHCP_IPADDR and the suggestion of a DHCP_OPTS parameter.

* Add SLAAC security and privacy options.Darren 'Tadgy' Austin2021-03-081-0/+10
| | | | | | | | | | This patch adds some security and privacy enhancements to SLAAC configuration. When SLAAC_PRIVIPGEN is "yes", address generation is enhanced with a secret key for the interface set in SLAAC_SECRET. This prevents predictable address generation. When SLAAC_TEMPADDR is "yes", a temporary address is used with SLAAC. Thanks to davjohn from LQ for the inital patches and help testing.

* Implement a new IPADDRS array for v4 IPs - read full commit messageDarren 'Tadgy' Austin2021-02-271-24/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit introduces the logic for a new IPADDRS array which will work in a similar way to the IPv6 IP6ADDRS array. The IPADDRS array can hold multiple IPv4 addresses with netmasks, which are used in preference to, but maintaining backwards compatibility with, the old IPADDR/NETMASK arrays. If IPADDRS is set for an interface, the IPs and netmasks configured in the array are set before an also configured IPADDR/NETMASK. This maintains backwards compatibility - users can continue to use the IPADDR/NETMASK and IPALIASES arrays to configure the interface and completely ignore IPADDRS, or keep their old rc.inet1.conf files, if they so wish. If the IPADDRS arrays contains multiple IPs, those IPs are all added to the interface regardles of whether any IP in IPADDRS is or is not set. These IPs will also be added to the interface just as with IPALIASES if DHCP/SLAAC is used to set the first IP. The IPALIASES IPs are also added to the interface to maintain backwards compatibility. IPa set in IPADDRS to be used as 'alias' interfaces, are NOT given the usual ethX:Y name, like the IPs listed in IPALIASES. To get an ethX:Y interface the iPALIASES array should be used; to have the IPs simply added to the interface the user should use the IPADDRS array with multiple (space separated) IPs and netmasks. Using IPALIASES along side IPADDRS is completly legal and maintains backwards compatibility - it would yield a mixture of IPs set with and without ethX:Y aliases. This changeset moves the IPv4 configuration to be on par with the new IPv6 configuration syntax, but maintains FULL backwards compatibility with the old style syntax. Additionally, handling of IP4ADDRS has been modified such that it matches the IPADDRS usage. That is, any IPs listed in IP6ADDRS are also added to the interface (just as IPADDRS and IPALIASES are added for v4) whether the interface is configured with DHCP/DHCP6/SLAAC or not. This is a change to the IP6ADDRS usage, but since this script hasn't been officially accepted, there is no backwards compatibility issues. Again, note that these changes DO NOT change previous behaviour or damage backwards compatability. New functionallity and semantics only change behaviour of non-released features, so there is no bother to the changes. netconfig will be modified to output the new IPADDRS syntax, just as it does for IP6ADDRS and both will allow multiple IPs to be specified at configuration time - this is an improvement on the current netconfig behaviour.

* Remove BONDOPTS, VLANOPTS and BROPTS and replace with generic IFOPTS.Darren 'Tadgy' Austin2019-11-131-14/+19
| | | | | | | | | | Previously we had an xOPTS variable for each type of interface that could be configured. I've replaced this with a generic IFOPTS option which can be used to supply interface type specific options to 'ip'. As the option is now generic, it can be applied to physical interfaces too; so interfaces such as eth0 can have options applied just like a virtual interface.

* Added support for a BROPTS variable to set bridge specific settings.Darren 'Tadgy' Austin2019-11-131-7/+12
| | | | | | | Before, it was not possible to set bridge specific options when creating a bridge. This option adds the ability to set options via a BROPTS variable, which takes a pipe (|) delimited set of options as documented in the ip-link(8) man page (search for "BRIDGE Type Support").
* Create and document a new VLANOPTS variable.Darren 'Tadgy' Austin2019-11-131-0/+6
| | | | | This variable can be used to set custom options to configure the VLAN interface. It does not need to be used in 'normal' operation with a VLAN.
* Initial support for bonding (link aggrigation) in rc.inet1.Darren 'Tadgy' Austin2019-11-131-0/+17
| | | | | | | | | | | | | | | | | | | The bonding code introduces three new variables for use in rc.inet1.conf: BONDNICS[x]="" BONDMODE[x]="" BONDOPTS[x]="" The BONDNICS variable takes a list of interfaces which should be slaved to the bond. BONDMODE sets the mode of the bond. Useful options are 'balance-rr', 'active-backup' and '802.3ad'. A full list of options can be found in /usr/src/linux/Documentation/networking/bonding.txt and README.bonding. BONDOPTS are a pipe (|) separated list of options to apply to the bond after the interfaces have been added. Useful options are 'primary' (which is required when BONDMODE is 'active-backup', 'xmit_hash_policy' (which can be used with 'balance-rr' to choose the hash policy, 'lacp_rate' (which should be used with '802.3ad' mode), and 'miimon' (which should be used with all modes) See the kernel source documentation or README.bonding for more info.

* New configuration methodology - see full commit log.Darren 'Tadgy' Austin2019-11-061-6/+2
| | | | | | | | | | | It occurred to me that IPv6 addresses don't really need to have IP6ALIASES since all IPs are just added to the interface itself. So I've changed the syntax from using IP6ADDR + PREFIXLEN + IP6ALIASES to using just a single IP6ADDRS array, which takes a list of IP addresses with a prefix length in a space separated list. eg: IP6ADDRS[0]="a:b:c:d::1/64 1:2:3::1/48" If the prefix length is omitted a /64 length is assumed and a warning emitted.

* rc.inet1*: Simplify virtif_* code, add note to example configJakub Jankowski2017-11-211-1/+3
| | | | | | | | | | | | | There is a built-in way of counting the number of elements in an array: ${#arrayname[@]}. Use this, and the fact that "for i in $(seq 0 -1)" will not evaluate body of the loop even once, to simplify code and get rid of virtif_determine(). While at it, add a note to rc.inet1.conf mentioning the necessity of keeping array indexes monotonically increasing (from 0), otherwise the code will fail (so would the original code).

* rc.inet1.*: Added support for IP address aliasesRobby Workman2017-07-141-0/+5
| | | | | | | | | | | | | This is accomplished with a new parameter in rc.inet1.conf: IPALIASES[$index]="space separated list of addresses" The aliases are added with a /32 mask and a label of ${interface}:{$number} to remain compatible with net-tools. IP address aliases are supported for both statically configured interfaces and dhcp-configured interfaces, although they'll only be configured for dhcp if the dhcpcd call succeeds. * note: I don't what happens if dhcpcd gets IPv4LL address
