When you have multiple addresses on the same network on different interfaces (such as when you are part of a carp pool), and you run rpcbind -h to restrict which interfaces have rpc services, rpcbind can none-the-less return addresses that aren't in the -h list. This patch enforces the rule that when you specify -h on the command line, then services returned from rpcbind must be to one of the addresses listed in -h, or be a loopback address (since localhost is implicit when running -h). The root cause of this is the assumption in addrmerge that there can be only one interface that matches a given network IP address. This turns out not to be the case. To retain historical behavior, I didn't try to fix the routine to prefer the address that the request came into, since I didn't know the side effects that might cause in the normal case. My quick analysis suggests that it wouldn't be a problem, but since this code is tricky I opted for the more conservative patch of only restricting the reply when -h is in effect. Hence, this change will have no effect when you are running rpcbind without -h. Reviewed by: alfred@ Sponsored by: iX Systems MFC after: 2 weeks |

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
