03df31a6fc Please repeat after me: setusercontext() modifies _current_ environment, but 
sshd uses separate child_env. So, to make setusercontext() really does
something, environment must be switched before call and passed to child_env
back after it.

The error here was that modified environment not passed back to child_env,
so all variables that setusercontext() adds are lost, including ones from
~/.login_conf

43e73ba0c2 Change the FreeBSD version addendum to "FreeBSD-20020402". This shortens 
the version string to 28 characters, which is below the 40-character limit
specified in the proposed SECSH standard.  Some servers, however (like the
one built into the Foundry BigIron line of switches) will hang when
confronted with a version string longer than 24 characters, so some users
may need to shorten it further.

This is the standard BSD license with clause 3 removed and clause 4
suitably renumbered.

a2a887b56a output_data(), output_datalen() and netflush() didn't actually guarantee 
to do what they are supposed to: under some circumstances output data would
be truncated, or the buffer would not actually be flushed (possibly leading
to overflows when the caller assumes the operation succeeded).  Change the
semantics so that these functions ensure they complete the operation before
returning.

Comment out diagnostic code enabled by '-D reports' which causes an
infinite recursion and an eventual crash.

Patch developed with assistance from ru and assar.

40e7fc1a20 More potential buffer overflow fixes. 
o Fixed `nfrontp' calculations in output_data().  If `remaining' is
  initially zero, it was possible for `nfrontp' to be decremented.

Noticed by:	dillon

o Replaced leaking writenet() with output_datalen():

:  * writenet
:  *
:  * Just a handy little function to write a bit of raw data to the net.
:  * It will force a transmit of the buffer if necessary
:  *
:  * arguments
:  *    ptr - A pointer to a character string to write
:  *    len - How many bytes to write
:  */
: 	void
: writenet(ptr, len)
: 	register unsigned char *ptr;
: 	register int len;
: {
: 	/* flush buffer if no room for new data) */
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
: 	if ((&netobuf[BUFSIZ] - nfrontp) < len) {
: 		/* if this fails, don't worry, buffer is a little big */
                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
: 		netflush();
: 	}
:
: 	memmove(nfrontp, ptr, len);
: 	nfrontp += len;
:
: }  /* end of writenet */

What an irony!  :-)

o Optimized output_datalen() a bit.

b33edd3956 Bug fix: When the client connects to a server and Kerberos 
authentication is  enabled, the  client effectively ignores  any error
from krb5_rd_rep due to a missing branch.

In  theory  this could  result  in  an  ssh  client using  Kerberos  5
authentication accepting  a spoofed  AP-REP.  I doubt  this is  a real
possiblity, however, because  the AP-REP is passed from  the server to
the client via the SSH  encrypted channel.  Any tampering should cause
the decryption or MAC to fail.
