* Workaround a 14 year old BSD issue where initial address lifetimes
are transfered to the prefix route and are not updated again,
causing the kernel to remove the route.
The fix is to initially add the address with infinite lifetimes
and then change the lifetimes to the correct ones.
* IPv6 RA routes are now expired by dhcpcd.
* Fix gateway interface assignment on BSD.
* Only mask off signals we do something with
(allows coredumps on some platforms)
* Fix a memory issue where an old lease could be read and discarded
but the buffer length not reset.
* Bind DHCPv6 to the link-local address when not running in master
mode so that many dhcpcd instances can run per interface.
|
|
* It's now possible to exclude the vendor-class option.
* pkg-config can now be host selectable in configure,
thanks to Heiko Becker.
* Fixed a NULL pointer dereference when checking ARP conflicts.
* Revert a change in 6.11.1 which causes some packets not to be
read correctly from the BPF socket.
* Commandline options are now applied to profiles.
* Fixed some potential memory issues for non embebbeded configs,
thanks to Koichi Okamoto.
* Simplified route handling on BSD.
* Fix expiration of IPv6 routers if a static route was present.
* --inactive now starts with all interfaces inactive.
subsequent calls to dhcpcd can activate/deactivate them.
* Illumos (Solaris) is now a supported plaform.
|
|
* Fix truncated packet handling where the DHCP message is less than the
BOOTP size
* Rework the raw socket handling around an fd for initial Solaris support
* Only pull one message from the raw socket - eloop will handle the looping
* Netmask fixes for STATIC and INFORM
* Rework if_address to use struct ipv4_addr, like the ipv6 counter parts
* Split BSD handlink into many smaller functions to improve readability
* empty DNS entries are no longer created
* Test for hostname_fqdn being set to server or blank
* Allow an SLA 0 and prefix length of 0 to delegate the whole prefix
ia_pd 1 wm1/0
* Fix prefix delegation address timings on renew
|
|
* pidfile directory is now created correctly at startup.
* bootp "leases" are now stored so dhcpcd can dump them.
* ARP state is keep open so we can detect duplicates
(currently this is only logged, no action is taken).
* --lastleastextend allows dhcpcd to extend a DHCP lease once
it has expired. The lease is dropped if any other node
claims the address.
* Delegated Prefix reject routes will be correctly bound to the
loopback interface. If a delegated address uses the whole prefix,
then the reject route is removed. If this address is removed, the
reject route is restored.
* dhcp code has been reworked around a classic BOOTP structure
instead of a fixed size DHCP structure based on a max MTU of 1500.
Each reference to it also has a size so we know it's length.
Adding an option to a message is now guarded via easy macros.
Option concatenation buffer is no longer a fixed size.
* many more changes so that dhcpcd passes all current Coverity tests.

|
|
* Only run the IPv4LL script and rebuild routes on drop when
an address is actually dropped.
* Add noup directive to stop master mode bringing an interface up.
* Fix compile for old Linux systems.
* If only IPv4LL addresses exist, assign a default route to the
interface so that IPv4LL can talk to non IPv4LL on the same link.
* Set DHCPv4 MTU on routes instead of the interface.
This matches IPv6 behaviour and works around dodgy interfaces
where a MTU change can reset the PHY causing an infinite loop.
* MTU is now requsted by default in dhcpcd.conf again.
* noauthrequired also allows unauthenticated FORCERENEW and
RECONFIGURE messages.
* Simplify the socket code by adding a custom function instead of
having the same #ifdef mess for systems without SOCK_CLOEXEC.
Thanks to Christos Zoulas.
* Don't do platform init or setting interface MTU if too small when
testing or dumping leases.
* Build new_domain_name from other sources if blank before checking
it's blank to remove any prior config. Thanks to Paul Walrath.
* Describe adding an IPv6 temporary address.
* Don't delete dhcpcd assigned IPv6 link-local addresses when
releasing leases.

* Fix DHCPv6 elapsed time
|
|
* Fix IPv6 prefix underflow when confirming deprecated but valid leases
* eloop.c and .h are now 100% portable outside of dhcpcd
(provided the system supports recent POSIX and either you or
the system provide working TAILQ macros)
* Allow waitip to work per interface.
* Handle ND options in the same way we handle DHCP and DHCPv6 options.
* Add new variable of type bitflags:flags where the flags ABCDEFGH,
A is 10000000, B is 01000000, etc.
Variables with the name reserved are no longer processed.
* Improve IN_IFF_TENTATIVE with ip sharing.

* IPv6 default route only installed when a working address is added
* Fixed host routes inside a CSR option
* Support IN_IFF_TENTATIVE on NetBSD
|
|
* Clarify timeout and reboot timeout, make it more sane
* A server should not NAK an INFORM
* The noalias directive will now remove any IPv4 addresses existing on
the interface when we want to add our own
* For BSD systems stop polling for IPv6 router reachability
Instead, expect for cached neighour route additions/changes/removals
to be announced by the kernel. Currently only NetBSD-7.99.3 does this.
* Store acquired time for each IPv6 address so we can correctly offset
pltime and vltime if we need to re-add them
* test mode no longer turns off kernel rtadv handling
|
|
* Allow STOPPED to be processed by dhcpcd-run-hooks(8)
* Don't attempt to match IFT to ARP types directly
* If neither dig nor host are present, fallback to getent(1)
* If IFF_UP is not set when we get a carrier up event, poll for it
instead of giving up
* Failure to bind to the DHCP port on the wildcard address when
it's in-use is not an error
|
|

|
|
* Log which IP address we are ARPing.
* Only free other ARP states if not assinging an IPv4LL address.
* Reload global config when running per interface commands.
This matches the signal behaviour.
* If we don't have a hardware address, fallback to creating a default
IAID from the interface name and index as we used to.
* Loopback interfaces have routes scoped to the host only.
* If we don't have a hwlen and no clientid has been set, force a DUID
based ClientID.
* Disable IPv6RS if a loopback, pointopoint or not a multicast interface.
* If allowinterfaces is not specified, allow all configured interfaces
to work, such as loopback and ppp.
* When not daemonising, don't exit on timeout.
* Zero length UDP packets are not an error condition on the socket.
Thanks to Micha? K?pie?.
* If the IP address is still on the interface when reading a lease,
fake add the address and routes so the lease can be cleaned up if needed.
|
|
* TAILQ macros are now pulled in via config.h only so dhcpcd compiles
on systems where sys/queue.h does not exist at all
* Remove DHCP state correctly when the interface departs
* End the IPv4LL state when DHCP is stopped
* Ensure that any DHCP leased offered still exists when assigning an
IPv4LL address
|
|
* Log the address IPv4LL defends

* ARP code re-written to allow for many ARP states
* IPv4LL address is now pseudo random based on HW address instead
of really random as per RFC 3927 Section 2.1
* If not doing DHCP or DHCP6, disable the DNS requirement in the RA
to fork.

start IPv4LL at the same time as discover to ensure we have an
address quicker.
* Improve handling of the IPv6LL address at startup

|
|
* Use RTF_PINNED when deleting routes when available
Allows dhcpcd to control IPv4 routing on newer FreeBSDs

(should now fix all carrier problems on BSD virtual interfaces)
* Don't crash when processing IPv6 route calls from the kernel
when IPv6 resources have been disabled in dhcpcd
* Allow the same IP address to be shared across different interfaces
Interface with the lowest metric gets the IP address, will move
to the next highest if dropped (interface departs, carrier drops, etc)
* Use correct interface gateway on FreeBSD, removes need for linkaddr.c
on kFreeBSD
* Delegated prefix addresses are now reported via DELEGATE6
* Fix copying the correct timezone file
* Work better with unknown delegated prefix lengths
* Move IPv4LL and ARP to the DHCP eloop queue to fix timing issues
* Add IA PD documentation update from christos@netbsd.org
|
|
* Fix an unaligned access error on BeagleBone Black with FreeBSD.
Thanks to Guy Yur for the patch.
* Remove the fast loop trying to up an interface which does not
report carrier.
* Remove vis based encoding - instead validate against option type and
stop at invalid [1]
This removes all shell escaped encoding - dhcpcd will assume that IF
the --script option is a shell, it will quote variables correctly.
The stock dhcpcd-run-hooks does.
* dhcpcd -V now prints how the variables will be decoded.
* Changed some options in dhcpcd-definitions.conf to more sensible defaults.
* Don't daemonise on delegated address dad.
* Don't drop delegated reject route when forking.
* Fix IPv6 handling of link-local addresses on KAME stacks.
* Work on OpenBSD-5.6 without any special interface setup needed.
* Callout to handlecarrier when we don't have real carrier support and
rely on looking at IFF_UP and IFF_RUNNING.
This allows our hooks to know that dhcpcd thinks we have a carrier or not.
[1] DHCP option encodings defined in dhcpcd-definitions.conf
* domain (RFC3397)/dname (string) is strict domain name allowance
(ie, [alnum] with _- (but not at the start or end))
* string is now printable ascii (1-127) until invalid
* ascii is all ascii (1-127) until invalid
* raw is all chars (1-255) until NUL
* binhex is a hex representation of the option including embedded NULs
* ssid is still escpaed octal because it's expected to be human readable
AND can technically be all NUL
* everything else has strict option -> value encoding
|

* make test works again
* Many bounds checking fixes from Tobias Stoeckmann
* Improve error when the authentication token cannot be found
* close the IPv4 specific UDP socket when done sending
* Implemented a write queue to the control sockets
* Only send interfaces to control sockets when in a BOUND state
* Add a sample controlgroup directive to dhcpcd.conf to make setup easier
* Add variables if_oneup and if_ipwaited so hook scripts know the overall
state of dhcpcd better
* Pass RC_SVCNAME from enviromment to hooks so that a service hook can
know it's name (may not be dhcpcd)
* Document every variable set for dhcpcd-run-hooks(8)
* Use the nl80211 interface on Linux to get the wireless SSID if we fail
to get it via WEXT
* Allow SSIDs with non printable characters to be used in ssid selection
in dhcpcd.conf
* Add an unprivileged control socket so that normal users can obtain
dhcpcd running state
* Remove all instances of if_indextoname as we already know the index
* Only bring in linux/ipv6.h for linux AND glibc
* Add _DEFAULT_SOURCE #define to to make glibc-2.20 happy
* Check we have allocated IPv6 resources before checkings RA's
* configure errors are now logged to config.log
* Only hunt for a cross compiler if build != host
* Detect removal of IPv6 routes
* Don't add link-local addresses to POINTOPOINT interfaces
* Don't discard expired DHCPv6 leases when dumping them
* If a DHCPv6 lease has no timers, expire it right away
* Report delegated addresses
* Call dhcpcd-run-hooks correctly when delegated prefixes already exist
* Fix a memory error when ia_* config exists but IPv6 is disabled
* Ensure servername and bootfile are safely exported
* Sanitise the following characters using svis(3) with VIS_CTYLE and
VIS_OCTAL:
| ^ & ; < > ( ) $ ` \ " ' <tab> <newline>
This allows a non buggy unvis(1) to decode it 100% and stays compatible
with how dhcpcd used to handle encoding on most platforms.
For systems that supply svis(3) there is a code reduction, for systems
that do not, a slight code increase. This change mitigates systems
affected by bash CVE-2014-6271 and CVE-2014-7169.
