We can't export DES code from the United + * States to other countries (even though the code already exists + * outside the U.S. -- go figure that one out) but we need to make + * Secure RPC work. The normal way around this is to break the DES + * code out into a shared library; we can then provide a dummy lib + * in the base OS and provide the real lib in the secure dist, which + * the user can install later. But we need Secure RPC for NIS+, and + * there are several system programs that use NIS+ which are statically + * linked. We would have to provide replacements for these programs + * in the secure dist, but there are a lot, and this is a pain. The + * shared lib trick won't work for these programs, and we can't change + * them once they're compiled. + * + * One solution for this problem is to do the DES encryption as a system + * call; no programs need to be changed and we can even supply the DES + * support as an LKM. But this bloats the kernel. Maybe if we have + * Secure NFS one day this will be worth it, but for now we should keep + * this mess in user space. + * + * So we have this second solution: we provide a server that does the + * DES encryption for us.

This is similar to what Sun does with their ypxfrd + * protocol, but it must be stressed that this protocol is _NOT_ + * compatible with Sun's. There are a couple of reasons for this: + * + * 1) Sun's protocol is proprietary. The protocol definition is + * not freely available in any of the SunRPC source distributions, + * even though the NIS v2 protocol is. + * + * 2) The idea here is to transfer entire raw files rather than + * sending just the records. Sun uses ndbm for its NIS map files, + * while FreeBSD uses Berkeley DB. Both are hash databases, but the + * formats are incompatible, making it impossible for them to + * use each others' files. Even if FreeBSD adopted ndbm for its + * database format, FreeBSD/i386 is a little-endian OS and + * SunOS/SPARC is big-endian; ndbm is byte-order sensitive and + * not very smart about it, which means an attempt to read a + * database on a little-endian box that was created on a big-endian + * box (or vice-versa) can cause the ndbm code to eat itself. + * Luckily, Berkeley DB is able to deal with this situation in + * a more graceful manner. + * + * While the protocol is incompatible, the idea is the same: we just open + * up a TCP pipe to the client and transfer the raw map database + * from the master server to the slave. This is many times faster than + * the standard yppush/ypxfr transfer method since it saves us from + * having to recreate the map databases via the DB library each time. + * For example: creating a passwd database with 30,000 entries with yp_mkdb + * can take a couple of minutes, but to just copy the file takes only a few + * seconds. + */ + +#ifndef RPC_HDR +%#include +%__FBSDID("$FreeBSD$"); +#endif + +/* XXX cribbed from yp.x */ +const _YPMAXRECORD = 1024; +const _YPMAXDOMAIN = 64; +const _YPMAXMAP = 64; +const _YPMAXPEER = 64; + +/* Suggested default -- not necesarrily the one used. */ +const YPXFRBLOCK = 32767; + +/* + * Possible return codes from the remote server. + */ +enum xfrstat { + XFR_REQUEST_OK = 1, /* Transfer request granted */ + XFR_DENIED = 2, /* Transfer request denied */ + XFR_NOFILE = 3, /* Requested map file doesn't exist */ + XFR_ACCESS = 4, /* File exists, but I couldn't access it */ + XFR_BADDB = 5, /* File is not a hash database */ + XFR_READ_OK = 6, /* Block read successfully */ + XFR_READ_ERR = 7, /* Read error during transfer */ + XFR_DONE = 8, /* Transfer completed */ + XFR_DB_ENDIAN_MISMATCH = 9, /* Database byte order mismatch */ + XFR_DB_TYPE_MISMATCH = 10 /* Database type mismatch */ +}; + +/* + * Database type specifications.
