2010-04-19If interfaces are specified, get their rdomain and bind dhcpd into the sameClaudio Jeker
domain with setrdomain(). This allows to run dhcpd on multiple rdomains. OK krw@

2010-01-02Eliminate all uses of dmalloc() where the returned pointerKenneth R Westerback
is checked for NULL and a specific error/warning issued. Add two such manual warning/error checks and kill those dmalloc calls. And then there were none, so kill dmalloc(). Whew.
2010-01-01Eliminate all uses of dfree() where the pointer is either dereferencedKenneth R Westerback
immediately before the use or the pointer is checked for NULL before the call. And then there were none, so kill dfree().
2010-01-01Wrappers around a wrapper around free() are of no more use thanKenneth R Westerback
wrappers around wrappers around calloc(). The purpose of the free() wrapper is to generate an error message when free'ing NULL. But free_hash_bucket(), free_lease(), and free_tree() are all called immediately after dereferencing the pointer to be freed. Thus the error message will never be issued.
2010-01-01A slightly more complex calloc() wrapper wrapper, new_hash_table(),Kenneth R Westerback
bites the dust.
2010-01-01Another calloc() wrapper wrapper, new_tree(), bites the dust.Kenneth R Westerback
2010-01-01Two more calloc() wrapper wrappers, new_shared_network() andKenneth R Westerback
new_subnet(), bite the dust.
2010-01-01Single-use wrapper functions that just call a wrapper functionKenneth R Westerback
around calloc() and end up producing duplicate error messages are just confusing. Eliminate new_hash_bucket(), new_lease(), new_leases(), new_group().
2010-01-01Delete unused declarations.Kenneth R Westerback
2010-01-01Plug a potential leak similar to the one parfait spotted and TheoKenneth R Westerback
fixed. Eliminate the function new_class() by expanding the only use Use strdup() and calloc() rather than manually simulating them. No functional change.

2008-11-14Sigh. Some clients can't handle three DHO_PAD options holding spaceKenneth R Westerback
for an unused overload option. Noticed by mk@ when netbooting his G4 mac mini. So compact the options by shifting them over the unused option and filling the end by DHO_PAD. Tested by mk@.
2008-11-08Some clients don't parse a DHO_DHCP_OPTION_OVERLOAD option the wayKenneth R Westerback
I expected. They object if there are no bits set in the option value. So just use DHO_PAD in the reserved space unless at least one of the bits is set. Various versions tested by Tobias Ulmer on OpenSolaris, matthieu@ on busybox's DHCP client, and Uwe Dippel on Solaris. All of which failed before.
2008-09-15When checking if a syscall like open(), ioctl() or writev() failed compareClaudio Jeker
directly against -1 and do not use a < 0 test. OK henning@

incomplete buffer initialization and possible incorrect option handling. Thanks to Nick Bender ok krw@ deraadt@

2008-05-08don't break dhcpd when not using synch mechanisms..Bob Beck
2008-05-07Add synchronisation support for dhcpd - this allows for two dhcpd'sBob Beck
with the same configuration to be run on the same net and they will keep their lease files/state in synch, and therefore allowing you to run redundant dhcpd's. Synchronization code stolen from spamd, uses an hmac key in /var/db/dhcpd.key if it exists. ok krw@ deraadt@
2008-04-16Redo/clarify the logic for storing options in the various buffers.Kenneth R Westerback
While there, bail out quickly if no options can be stored, and avoid overflow buffers if building a bootp reply. Henning looked and didn't get upset. millert@ tested it for a few days and liked the look of it. canacar@ glanced at it.

too large. Fixes a problem where a nicely crafted packet could crash dhcpd. Nuke a superfluous declaration of store_options() while here. Problem found and fix tested by Peter Hessler. ok beck@ millert@ henning@

2007-12-23remove double word in comment;Jason McIntyre
2007-10-29More tweaking of option processing, this time around the creation ofKenneth R Westerback
the priority list. Add create_priority_list() and use it to consistantly merge mandatory, supplied and default option priority lists into a reliable and complete list of options sorted by priority. No intended functional change other than ensuring all options available are returned. "looks good" henning@ "OK, fair enough" millert@
2007-10-28Remove duplicate DHO_HOST_NAME entry and add missingKenneth R Westerback
DHO_DHCP_USER_CLASS_ID entry to dhcp_option_default_priority_list[]. Reformat list of numbers at the end of dhcp_option_default_priority_list[] so it is easy to see which options are defined. No functional change.
2007-10-27Rework option storing so the code is readable, and eliminate oddKenneth R Westerback
behaviour on several edge conditions. Feedback, suggestion & "I like the approach" millert@ "excellent" henning@.
2007-10-21Take even more care to ensure the max message size is atKenneth R Westerback
least as large as the minimum IP MTU. ok canacar@ henning@ millert@
2007-10-21Last bit of (planned) tidy up in cons_options(). Join some lines,Kenneth R Westerback
delete some blank lines, add some other blank lines, move expressions so calculations done only once. Eliminate extraneous ++'s. No functional change.
2007-10-21Tidy up, make usual case exit faster, eliminate variable. No functionalKenneth R Westerback
change. ok beck@
2007-10-19Make sure bufix is updated after copying options into the first overflowKenneth R Westerback
buffer. Actually use the second overflow buffer now that bufix is correct and the test for remaining options will work correctly. ok beck@
2007-10-19Be a bit more paranoid and initialize all valid options buffers withKenneth R Westerback
DHO_PAD (a.k.a. 0). Eliminate manual DHO_PAD'ing after DHO_END is put into the buffer. ok beck@
