* Use pw->pw_dir when chroot'ing, not _PATH_VAREMPTY.krw2019-08-061-4/+3

| | | | | | | ones that needed to be booted out of the pf table process. This avoids removing the same addess over and over. Problem report and original diff from Bertrand Provost.
* Close appropriate ends of pfpipe. Lets pf table process die when dhcpdkrw2015-02-071-1/+3
| | | | | | | | does. Pointed out by Bertrand Provost. ok henning@
* Replace <sys/param.h> with <limits.h> and other less dirty headers wherederaadt2015-01-161-3/+5
| | | | | | | | | possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)

* We run getopt() twice to know if dhcp-sync is used. To make this workclaudio2010-12-151-2/+2
| | | | | | | both getopt calls need the same optstring or the first getopt() call will end before parsing all arguments. Problem found and fixed supplied by m_athias OK millert@, deraadt@
* Fix the naming of interfaces and variables for rdomains and rtablesguenther2010-07-031-3/+3
| | | | | | | | | | | | 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
* If interfaces are specified, get their rdomain and bind dhcpd into the sameclaudio2010-04-191-7/+11

* This diff makes dhcpd able to manipulate pf tables on certain lease events.ckuethe2006-05-311-6/+38
| | | | | | | | | | | | | dhcpd is now able to place abandoned addresses into a table (to offer some protection against machines camping on an address) and remove them from the table if they are properly leased. When dhcpd assigns an IP to a new hardware address, it can remove that address from a table. This is for use with the overload table in pf; newly arrived machines will not be punished for the actions of a machine that went away. beck@ and krw@ liked previous versions of this, henning@ final ok
* If a list of interfaces is supplied via the command line orkrw2006-05-111-3/+2
| | | | | | | | | | | | | | | | | | | | dhcpd.interfaces then a) don't bother looking up information on interfaces that were not requested; b) don't exit if a requested interface is not found, just issue a warning message; c) exit if none of the interfaces were found. The command line for dhcpd shown in ps will continue to show requested but ignored interfaces. As usual with dhc* code, whack a bunch of unused states, constants, flags, etc. Since we only invoke discover_interfaces() with DISCOVER_SERVER, there is no need to keep track of other possibilities.
