* MFC: 1.3Jung-uk Kim2007-12-101-1/+4
| | | | | | | | | | | | | | | | | Teach dhclient(8) about net80211 link (association) status. Especially it helps ndis(4) where it is used with wpa_supplicant(8) since 0.5.8 is imported. Previously ndis_events(8) was used to notify link status to wpa_supplicant but it is defuct now, i. e., external event notification mechanism is removed by the vendor and there is no substitute for ndisulator yet.

| | | | | | | | | | | | | | The original DHCP specification includes a route option but it supports only class-based routes. RFC3442 adds support for specifying the netmask width for each static route. A variable length encoding is used to minimize the size of this option. PR: bin/99534 Submitted by: Andrey V.

While OpenBSD's solution of setting interface->rbuf_len to BPF_WORDALIGN(length) is safe due to the size of the buffer, I think this solution results in less hidden assumptions. This should fix the problem of dhclient running away and consuming 100% CPU.

* Fix rev 1.12.Brooks Davis2006-01-261-1/+1
| | | | | | | | | | | | | | | | /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 a predictable file in /tmp as root is a really bad idea since a malicious user may be able to win a race and insert a symlink which will allow them to cause any file to be overwritten. To solve these problems, create the tempory file in /var/run which will exist this early and is writable only by root. Security: Local risk if users can cause dhclient to run on demand (such as by unplugging and replugging the network cable). Notes: svn path=/head/; revision=154869

Specifically, the string must be no more than 256 bytes long and contain no more than six valid domain names separated by white space.

This solution is not perfect as it removes the ability to send NUL-terminated host-name options which may be required by some broken servers.
