ancient IBM LANMAN DHCP clients. Thanks to Jim Louvau for
help with this.
release 2.8
Pad DHCP packets to a minimum size of 300 bytes. This
fixes interoperability problems with the Linux in-kernel
DHCP/BOOTP client. Thanks to Richard Musil for
diagnosing this and supplying a patch.
Fixed option-parsing bug and potential memory leak. Patch
from Richard Musil.
Improved vendor class configuration and added user class
configuration. Specifically: (1) options are matched on
the netids from dhcp-range, dhcp-host, vendor class and
user class(es). Multiple net-ids are allowed and options
are searched on them all. (2) matches agains vendor class
and user class are now on a substring, if the given
string is a substring of the vendor/user class, then a
match occurs. Thanks again to Richard Musil for prompting
this.
Make "#" match any domain on --address and --server
flags. --address=/#/1.2.3.4 will return 1.2.3.4 for _any_
domain not otherwise matched. Of course
--server=/#/1.2.3.4 is exactly equivalent to
--server=1.2.3.4. Special request from Josh Howlett.
Fixed a nasty bug which would cause dnsmasq to lose track
of leases for hosts which had a --dhcp-host flag without
a name specification. The mechanism for this was that
the hostname could get erroneously set as a zero-length
string and then written to the leases file as a
mal-formed line. Restarting dnsmasq would then lose the lease.
Alex Hermann's work helped chase down this problem.
Add checks against DHCP clients which return zero-length
hostnames. This avoids the potential lease-loss problems
reffered to above. Also, if a client sends a hostname when
it creates a lease but subsequently sends no or a
zero-length hostname whilst renewing, continue to use the
existing hostname, don't wipe it out.
Tweaked option parsing to flag some parameter errors.
