freebsd kernel with SKQ
08760d5a57
In NetBSD, Solaris, xprt->xp_p2 pointed directly to the credentials,
in FreeBSD xprt->xp_verf.oa_base was a pointer to a struct cmessage,
which is defined as follow:
struct cmessage {
struct cmsghdr cmsg;
struct cmsgcred cmcred;
};
The credentials were submitted the right way and xprt->xp_p2 pointed to them.
But cb_verf.oa_flavor was still empty. There was an assignment missing
in svc_recv() in svc_vc.c:
msg->rm_call.cb_verf.oa_flavor = AUTH_UNIX;
Also
+ if (addr.ss_family == AF_LOCAL) {
+ xprt->xp_raddr = *(struct sockaddr_in *)xprt->xp_rtaddr.buf;
+ xprt->xp_addrlen = sizeof (struct sockaddr_in);
+ }
was missing. But the first seems not to be needed:
I guess in rpc.yppasswdd there was a typo:
- transp>xp_verf.oa_flavor != AUTH_UNIX) {
+ rqstp->rq_cred.oa_flavor != AUTH_UNIX) {
This little fix does fix the breakage in rpc.yppasswdd :-)
+ if (msg.msg_controllen == 0 ||
+ (msg.msg_flags & MSG_CTRUNC) != 0)
+ return (-1);
We cannot set the cb_verf.oa_length in svc_recv() of svc_vc.c,
the credentials get overwritten then, and that's bad.

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 ``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/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 have to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/i386/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.
