freebsd kernel with SKQ
0cfee0c223
These two bugs are closely related. The root cause is that ifa_ifwithnet does not consider FIBs when searching for an interface address. sys/net/if_var.h sys/net/if.c Add a fib argument to ifa_ifwithnet and ifa_ifwithdstadddr. Those functions will only return an address whose interface fib equals the argument. sys/net/route.c Update calls to ifa_ifwithnet and ifa_ifwithdstaddr with fib arguments. sys/netinet/in.c Update in_addprefix to consider the interface fib when adding prefixes. This will prevent it from not adding a subnet route when one already exists on a different fib. sys/net/rtsock.c sys/netinet/in_pcb.c sys/netinet/ip_output.c sys/netinet/ip_options.c sys/netinet6/nd6.c Add RT_DEFAULT_FIB arguments to ifa_ifwithdstaddr and ifa_ifwithnet. In some cases it there wasn't a clear specific fib number to use. In others, I was unable to test those functions so I chose RT_DEFAULT_FIB to minimize divergence from current behavior. I will fix some of the latter changes along with PR kern/187553. tests/sys/netinet/fibs_test.sh tests/sys/netinet/udp_dontroute.c tests/sys/netinet/Makefile Revert r263738. The udp_dontroute test was right all along. However, bugs kern/187550 and kern/187553 cancelled each other out when it came to this test. Because of kern/187553, ifa_ifwithnet searched the default fib instead of the requested one, but because of kern/187550, there was an applicable subnet route on the default fib. The new test added in r263738 doesn't work right, however. I can verify with dtrace that ifa_ifwithnet returned the wrong address before I applied this commit, but route(8) miraculously found the correct interface to use anyway. I don't know how. Clear expected failure messages for kern/187550 and kern/187552. PR: kern/187550 PR: kern/187552 Reviewed by: melifaro MFC after: 3 weeks Sponsored by: Spectra Logic |

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.
