options: Complete the transition to numeric toggles (`#if')
For the sake of review, this commit alters only the code; the affiliated
comments within the source files also need to be updated, but doing so
now would obscure the operational changes that have been made here.
* All on/off options have been switched to the numeric `#if' variant;
that is the only way to make this `default_options.h.in' thing work
in a reasonable manner.
* There is now some very minor compile-time checking of the user's
choice of options.
* NO_FAST_EXPTMOD doesn't seem to be used, so it has been removed.
* ENABLE_USER_ALGO_LIST was supposed to be renamed DROPBEAR_USER_ALGO_LIST,
and this commit completes that work.
* DROPBEAR_FUZZ seems to be a relatively new, as-yet undocumented option,
which was added by the following commit:
commit 6e0b539e9ca0b5628c6c5a3d118ad6a2e79e8039
Author: Matt Johnston <[email protected]>

split out checkpubkey_line() separately
It has now been added to `sysoptions.h' and defined as `0' by default.
* The configuration option `DROPBEAR_PASSWORD_ENV' is no longer listed in
`default_options.h.in'; it is no longer meant to be set by the user, and
is instead left to be defined in `sysoptions.h' (where it was already being
defined) as merely the name of the environment variable in question:
DROPBEAR_PASSWORD
To enable or disable use of that environment variable, the user must now
toggle `DROPBEAR_USE_DROPBEAR_PASSWORD'.
* The sFTP support is now toggled by setting `DROPBEAR_SFTPSERVER', and the
path of the sFTP server program is set independently through the usual
SFTPSERVER_PATH.

This file is out of date - it remains here in case it is still of use. The basic naming convention is svr- and cli- for seperate parts, then common- for common parts. Some files have no prefix. A brief rundown on which files do what, and their corresponding sections in the IETF drafts. The .c files usually have corresponding .h files. Transport layer draft-ietf-secsh-transport-16.txt =============== session.c Contains the main select() loop, and handles setting up/closing down ssh connections algo.c Framework for handling various ciphers/hashes/algos, and choosing between the lists of client/server preferred ones kex.c Key exchange routines, used at startup to negotiate which algorithms to use, and also to obtain session keys. This also runs when rekeying during the connection. packet.c Handles the basic packet encryption/decryption, and switching to the appropriate packet handlers. Called from session.c's main select loop. service.c Handles service requests (userauth or connection) Authentication draft-ietf-secsh-userauth-17.txt ============== auth.c General auth handling, including user checking etc, passes different auth types to auth{passwd,pubkey} authpasswd.c Handles /etc/passwd or /etc/shadow auth authpubkey.c Handles ~/.ssh/authorized_keys auth Connection draft-ietf-secsh-connect-17.txt ========== channel.c Channel handling routines - each shell/tcp conn/agent etc is a channel. chansession.c Handles shell/exec requests sshpty.c From OpenSSH, allocates PTYs etc termcodes.c Mapping of POSIX terminal codes to SSH terminal codes loginrec.c From OpenSSH, handles utmp/wtmp logging x11fwd.c Handles X11 forwarding agentfwd.c Handles auth-agent forwarding requests localtcpfwd.c Handles -L style tcp forwarding requests, setting up the listening port and also handling connections to that port (and subsequent channels) Program-related =============== dbmulti.c Combination binary chooser main() function dbutil.c Various utility functions, incl logging, memory etc dropbearconvert.c Conversion from dropbear<->openssh keys, uses keyimport.c to do most of the work dropbearkey.c Generates keys, calling gen{dss,rsa} keyimport.c Modified from PuTTY, converts between key types main.c dropbear's main(), handles listening, forking for new connections, child-process limits runopts.c Parses commandline options options.h Compile-time feature selection config.h Features selected from configure debug.h Compile-time selection of debug features includes.h Included system headers etc Generic Routines ================ signkey.c A generic handler for pubkeys, switches to dss or rsa depending on the key type rsa.c RSA asymmetric crypto routines dss.c DSS asymmetric crypto routines gendss.c DSS key generation genrsa.c RSA key generation bignum.c Some bignum helper functions queue.c A queue, used to enqueue encrypted packets to send random.c PRNG, based on /dev/urandom or prngd atomicio.c From OpenSSH, does `blocking' IO on non-blocking fds buffer.c Buffer-usage routines, with size checking etc vim:set ts=8:
