-TODO for 1.1 And Beyond
+TODO for 1.2 And Beyond
=======================
-NOTE: Any item that doesn't have (***DONE) in it, isn't done yet.
+NOTE: Any item that doesn't have (***DONE) in it, isn't done yet. The
+(***TESTING NEEDED) means that the item has been done but not yet properly
+tested.
+NOTE: A TODO entry does not mean that it is ever going to be done. Some
+of the entries may be just ideas, good, bad or ugly. If you want to work
+on some of the TODO entries simply let us know about it by dropping a note
+to silc-devel mailing list or appear on 'silc' channel on SILCNet.
-lib/silccore/silcpacket.[ch] ****DONE****
-============================
- o SilcPacketEngine. (***DONE)
+General
+=======
- o New SILC Packet API. (***DONE)
+ o Create apps/tutorial containing various Toolkit API tutorials.
+ o The Toolkit split. The Toolkit is to be splitted in parts. How many
+ parts and what the parts are isn't decided yet. Each part is a separate
+ software package. Current thinking is of the following:
-lib/silccore/silcpacket.[ch] ****PARTLY DONE****
-============================
+ SILC Toolkit SILC protocol, client and server library
+ SILC Runtime Toolkit runtime library
+ SILC Crypto Toolkit crypto, asn1, math, skr, pgp, etc.
- o IV Included flag support, UDP transport support (***TESTING NEEDED)
+ The rationale for this is of course that other than SILC projects
+ might like to use the various libraries SILC Toolkit provides, but
+ naturally they don't want the bloat of SILC protocol related stuff.
+ The Runtime library in SILC Toolkit is a general purpose runtime library,
+ like Glib and APR are. The runtime library is to be developed further
+ to provide alternative to Glib and APR.
-lib/silccore/silcid.[ch] ****DONE****
-========================
-
- o Add silc_id_str2id to accept the destination buffer as argument
- and thus not require any memory allocation. Same will happen
- with silc_id_payload_* functions. (***DONE)
-
- o silc_id_str2id, silc_id2str to non-allocating routines. (***DONE)
+ The Crypto library in SILC Toolkit is a general purpose crypto library
+ providing pretty nice APIs compared to many other crypto libraries,
+ especially OpenSSL. The Crypto library is to be developed further
+ to include support for OpenPGP, X.509 and SSH2.
lib/silccore
============
- o All payload encoding routines should take SilcStack as argument.
+ o SILC_PACKET_FLAG_ACK support. Implement ACK packet and packet payload
+ to silcpacket.c.
+ o All payload encoding routines should take SilcStack as argument.
-lib/silcske/silcske.[ch]
-========================
+ o All payload test routines into lib/silccore/tests/.
- o IV Included flag support in SKE (it currently doesn't accept it)
- o SilcConnAuth header file documentation.
+lib/silcclient, The Client Library
+==================================
+ o peer-to-peer private messages
+
+ o Private message key request notification to application. See XXX in
+ client_prvmsg.c.
+
+ o in JOIN notify handle resolving that timedout. Currently the user is
+ never joined the channel if this happens. What to do if message is
+ received from user that hasn't been resolved/joined?
-lib/silccrypt ****PARTLY DONE****
-=============
+ o Message ACKing support.
- o Implement the defined SilcDH API. The definition is in
- lib/silccrypt/silcdh.h.
+ o in /cmode and /cumode with +r, maybe the public key and private key
+ could be just some "string", which would then match to "string.pub" and
+ "string.prv".
- o SSH2 public keys support, allowing the use of SSH2 public keys in
- SILC.
- o OpenPGP certificate support, allowing the use of PGP public keys
- in SILC.
+Runtime library, lib/silcutil/
+==============================
- o SILC PKCS (silcpkcs.h) reorganizing when other PK supports added.
- Move the SILC Public Key routines away from the crypto library into
- the core library (silccore). silc_pkcs_public/private_key_* routines
- to silc_public/private_key_* routines. The silc_public_key_* routines
- should also automatically handle SILC Public Keys, and other keys
- and certificates as well. Add fe. silcpk.h into silccore. It should
- also include the Public Key Payload encoding and decoding routines.
- (***DONE)
+ o Fix universal time decoding (doesn't accept all formats) in silctime.c.
- o Add DSS support.
+ o Add functions to manipulate environment variables.
- o Cipher optimizations (asm, that this) at least for i386 would be nice.
+ SilcBool silc_setenv(const char *variable, const char *value);
+ const char *silc_getenv(const char *variable);
+ SilcBool silc_clearenv(const char *variable);
- o ECDSA and ECDH.
+ o Add functions to loading shared/dynamic object symbols (replaces the
+ SIM library (lib/silcsim) and introduces generic library). Add this
+ to lib/silcutil/silcdll.[ch].
+ SilcDll silc_dll_load(const char *object_path, SilcDllFlags flags);
+ void silc_dll_close(SilcDll dll);
+ void *silc_dll_getsym(SilcDll dll, const char *symbol);
+ const char *silc_dll_error(SilcDll dll);
-lib/silcutil ****PARTLY DONE****
-============
+ o Add directory opening/traversing functions
- o silc_stringprep to non-allocating version.
+ o silc_getopt routines
- o Compression routines are missing. The protocol supports packet
- compression thus it must be implemented. SILC Zip API must be
- defined.
+ o silc_hash_table_replace -> silc_hash_table_set. Retain support for
+ silc_hash_table_replace as macro.
+
+ o The SILC Event signals. Asynchronous events that can be created,
+ connected to and signalled. Either own event routines or glued into
+ SilcSchedule:
+
+ SilcTask silc_schedule_task_add_event(SilcSchedule schedule,
+ const char *event, ...);
+ SilcBool silc_schedule_event_connect(SilcSchedule schedule,
+ const char *event,
+ SilcTaskCallback event_callback,
+ void *context);
+ SilcBool silc_schedule_event_signal(SilcSchedule schedule,
+ const char *event, ...);
+
+ Example:
+ silc_schedule_task_add_event(schedule, "connected",
+ SILC_PARAM_UI32_INT,
+ SILC_PARAM_BUFFER,
+ SILC_PARAM_END);
+ silc_schedule_event_connect(schedule, "connected", connected_cb, ctx);
+ silc_schedule_event_signal(schedule, "connected", integer, buf,
+ SILC_PARAM_END);
+ SILC_TASK_CALLBACK(connected_cb)
+ {
+ FooCtx ctx = context;
+ va_list args;
+ SilcUInt32 integer;
+ SilcBuffer buf;
+
+ va_start(args, context);
+ integer = va_arg(args, SilcUInt32);
+ buf = va_arg(args, SilcBuffer);
+ va_end(args);
+ ...
+ }
+
+ Problems: Events would be SilcSchedule specific, and would not work on
+ multi-thread/multi-scheduler system. The events should be copyable
+ between schedulers.
+
+ o If the event signals are added, the SILC_PARAM_* stuff needs to be
+ moved from silcbuffmt.h to silctypes.h or something similar.
+
+ o In case the SILC Events are done we shall create a new concept of
+ parent and child SilcSchedule's. When new SilcSchedule is created a
+ parent can be associated to it. This association could be done either
+ directly by the parent or by any other children. This way the signals
+ would in effect be global and would reach all children schedulers.
+
+ This relationship would be associative only. The schedulers are still
+ independent and run independently from each other. All schedulers
+ would be linked and could be accessed from any of the schedulers.
+ It should be possible to retrieve the parent and enumate all children
+ from any of the schedulers.
+
+ SilcSchedule silc_schedule_init(int max_tasks, void *app_context,
+ SilcSchedule parent);
+ SilcSchedule silc_schedule_get_parent(SilcSchedule schedule);
+
+ o Structured log messages to Log API. Allows machine readable log
+ messages. Would allow sending of any kind of data in a log message.
+
+ o Base64 to an own API
+
+ o Timer API
o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
in separately.
- o bool -> SilcBool (***DONE)
+ o silc_stringprep to non-allocating version.
- o Silc FD Stream to WIN32 (lib/silcutil/silcfdstream.h)
+ o SilcStack aware SilcHashTable.
+ o SilcStack aware SilcDList.
-lib/silcutil/silcbuffer.h ****DONE****
-=========================
+ o Thread pool API. Add this to lib/silcutil/silcthread.[ch].
- o Remove the `truelen' field from SilcBuffer as it is entirely
- redundant since we can get the true length of the buffer by
- doing buffer->end - buffer->header. Add silc_buffer_truelen
- macro instead. Consider also removing `len' field too since
- it effectively is buffer->tail - buffer->data, and adding
- silc_buffer_len macro can do the same. These would save
- totally 8 bytes of memory per buffer. (***DONE)
+ typedef void (*SilcThreadPoolFunc)(SilcSchedule schedule,

+ of the `run' function. If `schedule' is non-NULL the `completion'

-lib/silcutil/silcstack.[ch] ****DONE****
-===========================
-
- o Data stack implementation (***DONE)
+ /* Stops all free and started threads. The minumum amount of threads
+ specified to silc_thread_pool_alloc always remains. */
+ void silc_thread_pool_purge(SilcThreadPool tp);
+ o Fast mutex implementation. Fast rwlock implementation. Mutex and
+ rwlock implementation using atomic operations.
-lib/silcutil/silcstream.[ch] ****DONE****
-============================
+ o Compression routines are missing. The protocol supports packet
+ compression thus it must be implemented. SILC Zip API must be
+ defined.
- o Add abstract SilcStream. (***DONE)
+ (o Generic SilcStatus or SilcResult that includes all possible status and
+ error conditions, including those of SILC protocol. Though, the SILC
+ protocol related status (currently in silcstatus.h) cannot be in
+ runtime library) maybe
+ (o SILC specific socket creation/closing routines to silcnet.h, wrappers
+ to all send(), recv(), sendto() etc. Bad thing is that we'd have to
+ define all socket options, sockaddrs, etc.) maybe
-lib/silcutil/silcsocketstream.[ch] ****PARTY DONE****
-==================================
+ (o mmap) maybe
- o Add SilcSocketStream (***DONE)
- o Add SilcSocketStream for WIN32
+lib/silcutil/symbian/
+=====================
- o Test QoS after the changes made to socket stream
+ o Something needs to be thought to the logging globals as well,
+ like silc_debug etc. They won't work on EPOC. Perhaps logging
+ and debugging is to be disabled on EPOC. The logging currently works
+ by it cannot be controlled, same with debugging.
-lib/silcutil/silcschedule*.[ch] ****DONE****
-===============================
+SFTP Library, lib/silcsftp/
+===========================
- o Scheduler can be optimized for FD tasks by changing the fd_queue
- to SilcHashTable instead of using linked list. We need to do
- one-to-one mapping of FD to task and hash table is more efficient
- for this usage.
+ o Read prefetch (read-ahead, reading ahead of time). Maybe if this can
+ be done easily.
- Also redefine the silc_select to perhaps return a separate
- structure of the events that actually occurred, instead of
- returning the events in the fd_list which is then traversed
- in the generic code to find the changed events. This can be
- made faster by having own struct which includes only the
- changed events, thus the tarversing is faster since the whole
- fd_list is not traversed anymore (it is still traversed in the
- silc_select but at least it removes one extra tarversing later
- for the same list).
- Other task queues should be changed to use SilcList. (***DONE)
+SKR Library, lib/silcskr/
+=========================
- o Add SILC scheduler's internal routines into a table of implementation
- function pointers, that the generic code then takes as extern from
- implementation. These are the silc_schedule_internal_* routines.
- (***DONE)
+ o Add fingerprint as search constraint.
+
+ o Add OpenPGP support. Adding, removing, fetching PGP keys. (Keyring
+ support?)
+
+ o Add support for importing public keys from a directory and/or from a
+ file. Add support for exporting the repository (different formats for
+ different key types?).
+
+ o Change the entire silc_skr_find API. Remove SilcSKRFind and just simply
+ add the find constraints as variable argument list to silc_skr_find, eg:
+
+ silc_skr_find(skr, schedule, callback, context,
+ SILC_SKR_FIND_PUBLIC_KEY, public_key,
+ SILC_SKR_FIND_COUNTRY, "FI",
+ SILC_SKR_FIND_USAGE, SILC_SKR_USAGE_AUTH,
+ SILC_SKR_FIND_END);
+
+ NULL argument would be ignored and skipped.
+
+ o Add OR logical rule in addition of the current default AND, eg:
+
+ // Found key(s) MUST have this public key AND this country.
+ silc_skr_find(skr, schedule, callback, context,
+ SILC_SKR_FIND_RULE_AND,
+ SILC_SKR_FIND_PUBLIC_KEY, public_key,
+ SILC_SKR_FIND_COUNTRY, "FI",
+ SILC_SKR_FIND_END);
+
+ // Found key(s) MUST have this public key OR this key context
+ silc_skr_find(skr, schedule, callback, context,
+ SILC_SKR_FIND_RULE_OR,
+ SILC_SKR_FIND_PUBLIC_KEY, public_key,
+ SILC_SKR_FIND_CONTEXT, key_context,
+ SILC_SKR_FIND_END);
+
+
+Crypto Library, lib/silccrypt/
+==============================
+
+ o Add fingerprint to SilcSILCPublicKey and retrieval to silcpk.h, and
+ possibly to silcpkcs.h.
+
+ /* Return fingerprint of the `public_key'. Returns also the algorithm
+ that has been used to make the fingerprint. */
+ const unsigned char *
+ silc_pkcs_get_fingerprint(SilcPublicKey public_key,
+ const char **hash_algorithm,
+ SilcUInt32 *fingerprint_len);
+
+ o Change SILC PKCS API to asynchronous, so that accelerators can be used.
+ All PKCS routines should now take callbacks as argument and they should
+ be delivered to SilcPKCSObject and SilcPKCSAlgorithm too.
+
+ /* Signature computation callback */
+ typedef void (*SilcPKCSSignCb)(SilcBool success,
+ const unsigned char *signature,
+ SilcUInt32 signature_len,
+ void *context);
+
+ /* Signature verification callback */
+ typedef void (*SilcPKCSVerifyCb)(SilcBool success, void *context);
+
+ /* Encryption callback */
+ typedef void (*SilcPKCSEncryptCb)(SilcBool success,
+ const unsigned char *encrypted,
+ SilcUInt32 encrypted_len,
+ void *context);
+
+ /* Decryption callback */
+ typedef void (*SilcPKCSDecryptCb)(SilcBool success,
+ const unsigned char *decrypted,
+ SilcUInt32 decrypted_len,
+ void *context);
+
+ Either add new _async functions or add the callbacks to existing API
+ and if the callback is NULL then the API is not async and if provided
+ it may be async. For example;
+
+ SilcBool silc_pkcs_sign(SilcPrivateKey private_key,
+ unsigned char *src, SilcUInt32 src_len,
+ unsigned char *dst, SilcUInt32 dst_size,
+ SilcUInt32 *dst_len,
+ SilcBool compute_hash, SilcHash hash,
+ SilcPKCSSignCb async_sign,
+ void *async_sign_context);
+
+ (if this is done then there's no reason why the buffers in the
+ callbacks cannot be the ones user gives here) or allow only async:
+
+ SilcBool silc_pkcs_sign(SilcPrivateKey private_key,
+ unsigned char *src, SilcUInt32 src_len,
+ SilcBool compute_hash, SilcHash hash,
+ SilcPKCSSignCb async_sign,
+ void *async_sign_context);
+
+ or add new:
+
+ SilcBool silc_pkcs_sign_async(SilcPrivateKey private_key,
+ unsigned char *src, SilcUInt32 src_len,
+ SilcBool compute_hash, SilcHash hash,
+ SilcPKCSSignCb async_sign,
+ void *async_sign_context);
+
+ o Change PKCS Algorithm API to take SilcPKCSAlgorithm as argument to
+ encrypt, decrypt, sign and verify functions. We may need to for exmaple
+ check the alg->hash, supported hash functions. Maybe deliver it also
+ to all other functions in SilcPKCSAlgorithm to be consistent.
+
+ o Add DSS support. Take implementation from Tom or make it yourself.
- o Change SILC_TASK_CALLBACK to non-static, and remove the macro
- SILC_TASK_CALLBACK_GLOBAL. (***DONE)
+ o Implement the defined SilcDH API. The definition is in
+ lib/silccrypt/silcdh.h. Make sure it is asynchronous so that it can
+ be accelerated. Also take into account that it could use elliptic
+ curves.
- o SILC Schedule API changes to WIN32.
+ o ECDSA and ECDH
+ o All cipher, hash, hmac etc. allocation routines should take their name
+ in as const char * not const unsigned char *.
-lib/silcutil/silcasync.[ch] ****DONE****
-===========================
- o Add SilcAsyncOperation to utility library. Any function that takes
- callback as an argument must/should return SilcAsyncOperation.
- (***DONE)
+SILC Accelerator Library
+========================
+ o SILC Accelerator API. Provides generic way to use different kind of
+ accelerators. Basically implements SILC PKCS API so that SilcPublicKey
+ and SilcPrivateKey can be used but they call the accelerators.
-lib/silcutil/silctime.[ch] ****DONE****
-===========================
+ Something in the lines of (preliminary):
- o SilcTime. (***DONE)
+ /* Register accelerator to system. Initializes the accelerator. */
+ Varargs are optional accelerator specific init parameteres. */
+ SilcBool silc_acc_register(SilcAccelerator acc, ...);
- o system time, universal, generalized. (***DONE)

-lib/silcutil/silcfsm.[ch] ****DONE****
-=========================
+ /* Return list of the registered accelerators */
+ SilcDList silc_acc_get_supported(void);
- o SILC Finite State Machine API. Replaces SILC Protocol API (***DONE)
+ /* Find existing accelerator. `name' is accelerator's name. */
+ SilcAccelerator silc_acc_find(const char *name);
+ /* Return accelerator's name */
+ const char *silc_acc_get_name(SilcAccelerator acc);
-lib/silcutil/silcnet*, lib/silcutil/*/silc*net* ****PARTLY DONE****
-===============================================
+ /* Accelerate `public_key'. Return accelerated public key. */
+ SilcPublicKey silc_acc_public_key(SilcAccelerator acc,
+ SilcPublicKey public_key);
- o Add UDP interface (***DONE)
+ /* Accelerate `private_key'. Returns accelerated private key. */
+ SilcPrivateKey silc_acc_private_key(SilcAccelerator acc,
+ SilcPrivateKey private_key);
- o Add UDP interface for WIN32
+ /* Return the underlaying public key */
+ SilcPublicKey silc_acc_get_public_key(SilcAccelerator acc,
+ SilcPublicKey public_key);
- o New network interfaces (***DONE)
+ /* Return the underlaying private key */

+ const SilcRngObject *rng; /* Accelerated RNG's */
+ } *SilcAccelerator, SilcAcceleratorStruct;
-lib/silcsftp
-============
+ Allows accelerator to have multiple accelerators (cipher, hash etc)
+ and multiple different algorithms and implementations (SHA-1, SHA-256 etc).
- o Porting to use the new util library.
+ SilcPublicKey->SilcSILCPublicKey->RsaPublicKey accelerated as:
+ SilcPublicKey->SilcAcceleratorPublicKey->SilcSoftAccPublicKey->
+ SilcPublicKey->SilcSILCPublicKey->RsaPublicKey
+ silc_acc_public_key creates SilcPublicKey and SilcAcceleratorPublicKey
+ and acc->pkcs->import_public_key creates SilcSoftAccPublicKey.
-lib/silcutil/epoc/*
-===================
+ o Implement software accelerator. It is a thread pool system where the
+ public key and private key operations are executed in threads.
- o lib/silcutil/epoc routines missing or not completed.
+ const struct SilcAcceleratorObject softacc =
+ {
+ "softacc", softacc_init, softacc_uninit,
+ softacc_pkcs, NULL, NULL, NULL, NULL
+ }
- o The PKCS#1 also calls global RNG (even though it is not used
- currently in SILC, the interface allows its use).
+ /* Called from silc_acc_private_key */
+ int silc_softacc_import_private_key(void *key, SilcUInt32 key_len,

+ SilcSoftAccPrivateKey prv = silc_calloc(1, sizeof(*prv));
+ prv->pkcs = acc->pkcs;
+ prv->private_key = key;
+ *ret_private_key = prv;
+ }
- o Something needs to be thought to the logging globals as well,
- like silc_debug etc. They won't work on EPOC. Perhaps logging
- and debugging is to be disabled on EPOC.
+ (o Symmetric key cryptosystem acceleration? They are always sycnhronouos
+ even with hardware acceleration so the crypto API shouldn't require
+ changes.) maybe
lib/silcmath
increased memory consumption with TFM, and the rare need for public
key operations in server.
- o Change LTM and TFM function names when importing to SILC tree to avoid
- rare linking problems on system that has same named symbols already in
- the system.
+ We want TFM's speed but not TFM's memory requirements. Talk to Tom
+ about making the TFM mp dynamic just as it is in LTM.
o The SILC MP API function must start returning indication of success
and failure of the operation.
o All utility functions should be made non-allocating ones.
-lib/silcasn1 ****PARTLY DONE****
+SILC XML Library, lib/silcxml/
+==============================
+
+ o SILC XML API (wrapper to expat). The SILC XML API should follow and
+ resemble Simple API for XML (SAX).
+
+
+lib/silcske/silcske.[ch]
+========================
+
+ o Ratelimit to UDP/IP transport for incoming packets.
+
+
+lib/silcasn1
============
- o ASN.1 library (***DONE)
+ o Negative integer encoding is missing, add it.
- o Header documentation missing. (***DONE)
+ o SILC_ASN1_CHOICE should perhaps return an index what choice in the
+ choice list was found. Currently it is left for caller to figure out
+ which choice was found.
- o Some string encodings missing (copy/paste matter). (***DONE)
+ o SILC_ASN1_NULL in decoding should return SilcBool whether or not
+ the NULL was present. It's important when it's SILC_ASN1_OPTIONAL
+ and we need to know whether it was present or not.
- o Negative integer encoding
+
+lib/silcpgp
+===========
+
+ o OpenPGP certificate support, allowing the use of PGP public keys
+ in SILC.
+
+
+lib/silcssh
+===========
+
+ o SSH2 public key/private key support, allowing the use of SSH2 keys
+ in SILC. RFC 4716.
lib/silcpkix
done per channel. It shouldn't receive the whole list just
because one client happened to be on same channel.
- o MAYBE: The SilcChannelClientEntry can be:
- SilcUInt32 address;
- SilcUInt32 mode;
-
- where address is SilcClientEntry address XOR SilcChannelEntry.
- You can get SilcClientEntry by doing client = chl->address XOR channel,
- and SilcChannelEntry by doing channel = chl->address XOR client.
- As long as the other pointer is always available when accessing the
- structure this can be done.
-
o Add reference counters to all Silc*Entry structures
o SERVICEs support (plugin, SIM)
seconds. Now it is possible to accept n incoming JOIN commands
and process them without any timeouts. THis must be employed because
each JOIN command will create and distribute the new channel key
- to everybody on the channel (Fix this to 0.9.x).
+ to everybody on the channel.
o Related to above. If multiple JOINs are received in sequence perhaps
new key should be created only once, if the JOINs are handeled at the same
key ends up being used.
o The CMODE cipher & hmac change problem (#101).
-
-
-lib/silcclient
-==============
-
- o Some form of rewrite to make it more efficient.
-
- o Clear up interfaces.
-
- o Remove silc_client_run and silc_client_run_one from calling SilcSchedule.
- Leave the scheduling entirely to application.
