fd6ecc18 - dhclient-script: cope with /32 address leases

Wed, 05 Oct 2022 10:11:07 +0000

dhclient-script: cope with /32 address leasesOn certain cloud platforms (Google Cloud, Packet.net and others) theDHCP server offers a /32 address. This makes adding the default routefail since it is not reachable via any interface. Linux'sdhclient-script seem to usually have a special case for that andexplicitly adds an interface route to the router's address.FreeBSD's dhclient-script already has a special case for when the routeraddress is the same as the leased address. Now also add one for whenit's a different address that doesn't fall in the interface's subnet.PR: 241792Event: Aberdeen hackathon 2022Submitted by: sigsys@gmail.comReviewed by: dch, kp, bz (+1 on the idea, not reviewed), thjMFC after: 1 week List of files: /freebsd-14.2/sbin/dhclient/dhclient-script

Tue, 13 Dec 2011 11:54:51 +0000

dhclient-script relied on incorrect behavior of SIOCAIFADDR ioctl,that changed 0.0.0.0/0.0.0.0 prefix to 0.0.0.0/255.0.0.0.In the r228313 this behavior was fixed, and since dhclient-scriptgot broken.I'm not sure this fix is a perfect one, it just changesdhclient-script to set 0.0.0.0/255.0.0.0 explicitly.PR: kern/163206 List of files: /freebsd-14.2/sbin/dhclient/dhclient-script

409139f0 - Support domain-search in dhclient(8)

Sun, 04 Dec 2011 14:44:31 +0000

Support domain-search in dhclient(8)The "domain-search" option (option 119) allows a DHCP server to publisha list of implicit domain suffixes used during name lookup. This optionis described in RFC 3397.For instance, if the domain-search option says: ".example.org .example.com"and one wants to resolve "foobar", the resolver will try: 1. "foobar.example.org" 2. "foobar.example.com"The file /etc/resolv.conf is updated with a "search" directive if theDHCP server provides "domain-search".A regression test suite is included in this patch undertools/regression/sbin/dhclient.PR: bin/151940Sponsored by Yakaz (http://www.yakaz.com) List of files: /freebsd-14.2/sbin/dhclient/dhclient-script

Add a new function is_default_interface() which determines if thisinterface is one with the default route (or there isn't one). Use it todecide if we should adjust the default route and /etc/resolv.conf.Fix the delete of the default route. The if statement was totally bogusand the delete only worked due to a typo.

f1bacaa5 - Fix rev 1.12.

Thu, 26 Jan 2006 21:05:39 +0000

Fix rev 1.12./tmp may not be writeable yet when dhclient is first run via/etc/rc.d/netif so using it may not work. Also, writing to apredictable file in /tmp as root is a really bad idea since a malicioususer may be able to win a race and insert a symlink which will allowthem to cause any file to be overwritten. To solve these problems,create the tempory file in /var/run which will exist this early and iswritable only by root.Security: Local risk if users can cause dhclient to run on demand (such as by unplugging and replugging the network cable).

When we fail to aquire a lease, our lease expires without a sucessfulrenewal, or we lose link, be more forceful about clearing interfacestate so another interface that connects to the same network has achance of working. This doesn't address attemping to connect to both atonce, but appears to allow unplugging from a wired interface and theninserting a wireless card that associates with an AP bridged to the sameLAN.
