* 20-resolv.conf now uses the correct variable for $IF_METRIC
* Exclude interface values when dumping the lease
* Parse static value subnet_mask when it exists instead of deriving from
ip address
* logger calls now resemble dhcpcd calls to syslog(3)
* Reject offered IP address if INADDR_BROADCAST or INADDR_ANY
* Change the route if source address has changed
* Note the address we are requesting in the broadcast log entry
* When operating on one interface, respect the timeout for in dhcpcd.conf
* Escape | and & characters before passing the value to the shell
Ensure we set a valid hostname, DNS domain and NIS domain.
Document the need for input validation in dhcpcd-run-hooks(8).
Fixes CVE-2011-996
Based on a patch to dhcpcd-3 by Marius Tomaschewski <mt@suse.de>
* syntax in 50-ypbind hook has been fixed
* man page corrections
* report hwaddr used by dhcpcd when debug is enabled
* Fix detecting inet address for INFORM support
* document reason RELEASE in dhcpcd-run-hooks
* Support RTM_CHGADDR in the upcoming NetBSD-6
This is used to work out if the hwaddr has changed as the interface
does not go down/up unlike other OSes
* ntp hook no longer attempts to restart ntpd if 1st attempt failed
* Use dynamically sized buffers for reading kernel link events
* Use the active link address
* Added option to dump a lease to stdout
* TEST mode now works correctly if an old lease is NAKed
* routes with the gateway = leased ip are now treated as host routes
* Fix crash when using clientid and the interface re-configures
* log the pid of dhcpcd
* Indicate server IP received message from even if server ID not
present
* Fix crashes on IPv4LL failure and add more logging
* VendorID is now dhcpcd-$version:$OS-$version:$machine:$platform
* IPv4LL address range can now be used in DHCP requests
* sysctl net.ipv4.conf.$iface.promote_secondaries enabled on Linux
This resolves a long standing issue of changing ip on the same subnet.
* IPv4LL correctly resets the DHCP timer.
* -H, --xidhwaddr uses the last 4 bytes of the hardware address as
the DHCP xid
* -J, --broadcast tells the DHCP server to broadcast replies
* no longer warn about InfiniBand being an unsupported family
* infinite lease times are valid when reading old leases
* discard address correctly if lease is invalid
Changes from dhcpcd-5.1.3 include:
* dhcpcd logs even in quiet mode.
* Sleep for 1/100th of a second to give time for kernel to send RELEASE.
* -S option now works.
* Only warn about using CSR on bind.
* waitip is enabled when running on a single interface.
* Classless Static Routes are now enabled by default in dhcpcd.conf
instead of being always being requested.
* ClientID is now reported when interface starts.
* -w, --wait forces dhcpcd to wait until an interface gets a lease or
times out.
* Ensure DHCP socket is open when sending a DECLINE.
* Uses new hwaddr if existing interface is downed and then changed.
* No longer works on firewire interfaces by default.
dhcpcd-5.1.2 has a new behaviour change - when starting up and at least 1
interface has a carrier then it tries to get a lease or times out.
It still daemonises regardless. This, along with the -b and -w flags
allows total control over the desired behaviour of dhcpcd.
Changes from dhcpcd-5.0.7 include
* Only allow hardware families we know by default (over-ridable)
* Fix persistent and timeout 0 options
* Fix parsing of escape code sequencies
* Don't bring up interfaces brought down when handling new interfaces
* Allow un-encapsulated vendor option
* Don't null terminate gratuitously when handling quotes
* Fix various typos and grammatical errors
* dhcpcd.conf simplified a little
Changes from dhcpcd-5.0.6 include:
* Fix -f path/to/config
* -e, --env var=value for profile specific env vars
* Many issues resolved when running in test mode
* Don't print a (null) string when there is no NAK message
* read ssize_t instead of size_t when checking signals
Changes from dhcpcd-5.0.5 include
* Fix crash on MIPS, fixes PR bin/41682
Thanks to Tim McIntosh <tmcintos@eskimo.com> for the patch
* Save and restore interface MTU when changing
* IP whitelist
* Ensure that the lease and pidfile directories exist at startup
Changes from dhcpcd-5.0.3 include
* ServerID requirement in DHCP messages can be toggled in dhcpcd.conf
* If MTU is requested, don't apply if less than 576
* Enforce a minimum lease time of 20 seconds
Changes from 5.0.1 include
* -n option now starts dhcpcd if not already started
* 29-lookup-hostname hook installed by default, but skipped in dhcpcd.conf
* Fix warning about missing dirs if we don't have any existing state
* Fix compile on some Linux distros re linux/wireless.h
Major changes from dhcpcd-4 include
* Single daemon can now run DHCP on multiple interfaces at the same time
* Configuration profiles per interface, ssid, arping and fallback
* Listens to 3rd party programs changing routing information
* Supports DHCP INFORM over PPP
* Can configure static options for destination address
* Control socket so 3rd party program can control or listen directly
to dhcpcd events
* Is also a BOOTP client
Fixed since dhcpcd-4.0.12 include
* Every DHCP message now requires a ServerID as some rogue DHCP servers
NAK without one.
* Extra UDP validation is now done for testing dhcpcd over a loopback
Fixes since dhcpcd-4.0.11 include:
* Logging to LOG_DAEMON instead of LOG_LOCAL0
* Checking for POLLERR and POLLNVAL
* Only opening raw sockets when we have a working link
