2010-09-24Make it possible to use "dhclient egress" to refetch a lease withoutClaudio Jeker
rememberingwhich interface dhclient was actually active on. Requested by deraadt, OK deraadt@, krw@
2010-07-03Fix the naming of interfaces and variables for rdomains and rtablesPhilip Guenthe
and make it possible to bind sockets (including listening sockets!) to rtables and not just rdomains. This changes the name of the system calls, socket option, and ioctl. After building with this you should remove the files /usr/share/man/cat2/[gs]etrdomain.0. Since this removes the existing [gs]etrdomain() system calls, the libc major is bumped. Written by claudio@, criticized^Wcritiqued by me
2010-07-02garbage collect an unused function; ok claudioTheo de Raadt
2010-06-26malloc/strlcpy -> strdup. Apparently I forgot to commit this one withKenneth R Westerback
the similar changes to dhcpd.
2010-06-26Whitespace.Kenneth R Westerback
2010-06-02Have dhclient obey the interface's rdomain, instead of doing routes onPeter Hessler
rdomain 0. OK krw@, claudio@ sharp stick prodding from claudio@
2010-04-04Add some ipv6 hooks the isc code expects for dhcpv6.Jonathan Gray
ok krw@ ramdisks checked by deraadt@
2010-03-25be more strict in check_option().Kevin Steves
ISC dhclient had a buffer overflow: http://www.kb.cert.org/vuls/id/410676 and while our dhclient is not vulnerable to that, it got us looking at how the subnet mask option is handled. this limits specific ip address options to length 4 in conformance with RFC 2132. discussion started by william@ and with input from krw@ ok krw@
2009-11-26Silence dhclient by immediately exiting if the interface doesn't existKenneth R Westerback
or can't return important flags via ioctl. Excess verbiage pointed out by deraadt@. ok henning@
2009-11-12Make sure we have enough space for the trailing \0 on prepend/appendJonathan Gray
of dhcp options. found by parfait. ok krw@
2009-07-19use addr_eq() where we can; ok krw@Kevin Steves
2009-06-12state_panic() tries the active then other valid leases by setting theKevin Steves
interface to each address and trying to ping the gateway. This will trigger an RTM_NEWADDR message. routehandler() only checks for the active and alias address in RTM_NEWADDR messages, so we can exit when state_panic() and the message address is on client->leases. routehandler() needs to also check client->leases. testing krw, 'I say commit' krw
2009-06-06Nuke debug() unless DEBUG is defined. Elminates debug output fromKenneth R Westerback
normal operations. Prodded by deraadt@ a while ago.
2009-06-03Use the new powerful route flush to clean up the mess. With this multipleClaudio Jeker
dhclient can more or less peacefully coexist. OK beck@ krw@
2009-06-03remove unneeded ARGSUSED; ok krw@ henning@Kevin Steves
2009-05-27add missing else; from ISC.Kevin Steves
this fixes an old, old bug that could cause lease entries to be lost when initially loading client leases. found while looking for another issue. ok krw@
2009-05-25log the reason before we die in routehandler(); ok krw@ henning@Kevin Steves
2009-05-20Do not fall back to using nobody if _user is missing, butThordur I. Bjornsson
error out. Add a new user _rwalld for rpc.rwalld, and use that instead of nobody, also unconditionally drop to _rwalld not only if rpc.rwalld was started with euid 0 (as root). ok deraadt@
2009-03-31claudio has spent too much time with the mbuf macros.David Gwynne
switch the rtsocket message filter specification so you can or the macros converting the routing socket message types into the mask used by the filter. ie: - ROUTE_SETFILTER(rtfilter, RTM_NEWADDR); - ROUTE_SETFILTER(rtfilter, RTM_DELADDR); - ROUTE_SETFILTER(rtfilter, RTM_IFINFO); - ROUTE_SETFILTER(rtfilter, RTM_IFANNOUNCE); + rtfilter = ROUTE_FILTER(RTM_NEWADDR) | ROUTE_FILTER(RTM_DELADDR) | + ROUTE_FILTER(RTM_IFINFO) | ROUTE_FILTER(RTM_IFANNOUNCE); there's a manpage change coming. ok claudio@
2009-03-10Add 6-byte MAC address to the log entries for DHCP ACK/NAK/OFFER.Kenneth R Westerback
Log the packets before checking the client state. Makes it easy to find MACs for 'surprise' DHCP servers. Positive comments from mbalmer@, jasper@.
2009-02-19'(ifi->linkstat && ifi && ifi->rfdesc != -1)' is flawed. Swap theKenneth R Westerback
first two terms so ifi is checked first.
2009-02-01Let this compile with gcc2.Miod Vallat

2009-01-24improve indentation without wasting space on the install media;Igor Sobrado
make source code fit on 80-column displays; while here, remove superfluous comment sign. ok krw@
2009-01-24Improve comment about resolv.conf creation. Prodded by sobrado@.Kenneth R Westerback
2009-01-10Use the kernel set ifam_hdrlen so that ABI changes won't cause olderClaudio Jeker
binaries to stop working. OK krw@, michele@, henning@, dlg@
2008-10-05- talk about the "client configuration script" consistenlyJason McIntyre
- Xr dhclient-script on first mention, which is section 8 not 5 ok krw
2008-10-05Oops. Missed one typo jmc@ spotted.Kenneth R Westerback
2008-10-05Clarify discussion of option modifiers. They only affect values passedKenneth R Westerback
to dhclient-script. Our default script only uses a few options so others are unaffected by option modifiers. PR#5834 is thus rendered moot. Feedback & suggestions from jmc@, ok deraadt@.
2008-06-07stop spurious "got link" which nooone noticed, but everyone should have; ok krwTheo de Raadt
2008-05-26If an interface has no link at startup, try to force it up, and thenTheo de Raadt
give it about 4 seconds of (silent) grace period before doing the verbose search for a link... tested by various developers who got burned a bit
2008-05-09- don't give up when the link is not available on startup: dhclientReyk Floeter
goes to background and listens on the routing socket for link to come up before it retries. - renew the lease whenever the link was lost and becomes active again. - listen for link state changes on non-ethernet devices like wireless, the link state becomes active when the wireless has been associated to the AP and becomes active. this helps to automatically renew the lease when the user is roaming. ok beck@, deraadt@

2007-08-11Kill a couple of 'echo' statements that can never produce visibleKenneth R Westerback
output. i.e. not visible on the screen, nor in any log. If nothing else, makes dhclient-script smaller for install media. 'yesh kill' (sic) henning@

outside of the `spaces' array when trying to print the caret marker found by "Matthew R. Dempsky" <mrd@alkemio.org>, fix inspired by a.velichinsky@gmail.com. discussed with krw
2007-02-25No point in using zero'd fields in the parsed options. Use the optionsKenneth R Westerback
in the lease, whence the parsed info was moved. Fixes "Bogus servername" messages when processing an offer and stops bogus filename info from being stored in the lease. Found while testing a Tucson hotel's dhcp service. ok @stevesk "looks good" henning@.
