Implement SSID suffix stringes in pton()/ntop() to make it more
straightforward to specify addresses to bind, connect to, or add routes
for
Changes:
* Implement SSID suffix string formatting in patty_ax25_ntop(); drop
the 'ssid' pointer argument
* Implement SSID suffix string parsing in patty_ax25_pton(); drop
the 'ssid' argument
* Change all calls to patty_ax25_ntop() and patty_ax25_pton() to use
their new calling convention
Changes:
* Fix Classes of Operations and HDLC parameter bit flags in
include/patty/ax25.h to match the documentation after more careful
analysis; resolve issues with byte order
* Add support for previously missing HDLC parameters to function
patty_print_params()
* Fix Info TX/RX field encodings to be in bits, rather than bytes
* Implement patty_ax25_sock_realloc_bufs() to reallocate buffers
based on current window and I frame sizes
* Implement patty_ax25_sock_params_upgrade() to upgrade a socket's
parameters to the AX.25 v2.2 documented defaults; this will not
change parameters if the socket is already set to v2.2
* Implement patty_ax25_sock_params_max() to upgrade a socket's
parameters to the highest values supported by patty
* Reimplement patty_ax25_sock_send_xid() to send highest desired
parameters, rather than the values currently set on the socket
* When receiving XID frames destined to listening sockets, use
patty_ax25_sock_params_max() to negotiate from high to low
parameters
* When receiving SABME flags, use patty_ax25_sock_params_upgrade()
to ensure at least base AX.25 v2.2 parameter defaults are set
* Fix issue where outbound connections initiated with XID were
unable to time out after N retries
Changes:
* Implement patty_ax25_params struct to contain all parameters
supported by patty, at the interface and socket level alike
* Move parameter enumerate types into include/patty/ax25.h, from
include/patty/ax25/frame.h; make corrections as necessary
* Reimplement patty_ax25_frame_decode_xid() to parse known XID
information parameters into a patty_ax25_params object
* Implement patty_print_params() in src/print.c
* Refactor patty_print_frame() as patty_print_frame_header(),
without a call to patty_print_hexdump(); this allows
patty_print_params() to be called prior to patty_print_hexdump(),
for better readability
* Use patty_print_params() in examples/ax25dump.c, decode.c
* Refactor usage of patty_ax25_frame_decode_xid() in src/server.c to
parse XID frames into a patty_ax25_params object
Implement better handling of command/response bits whilst decoding and
encoding addresses
Changes:
* Add an enum patty_ax25_frame_cr argument to functions in
src/sock.c which send specific types of frames
* Detect AX.25 version >2.0 based on the command/response SSID bits
* Simplify address copying/encoding by usage of the new function
patty_ax25_addr_copy()
* Implement showing AX.25 version, command/response indicator for
frames in src/print.c
Changes:
* Split patty_ax25_frame_decode() into the following:
- patty_ax25_frame_decode_address()
- patty_ax25_frame_decode_control()
This allows for look up an established socket for a given address
pair, to determine if an SABME session is in progress,
necessitating modulo-128 control decoding
* Decode I and S N(R), N(S) sequence numbers, poll/final
bits properly in both modulo-8 and modulo-128 mode
* Perform better frame control validation
* Implement the following functions in src/sock.c:
- patty_ax25_sock_send_rr()
- patty_ax25_sock_send_rnr()
- patty_ax25_sock_send_rej()
- patty_ax25_sock_send_srej()
Corresponding functions have been removed from src/server.c
* Implement better functions in src/sock.c for encoding frame
control, with send/receive sequences associated with the socket,
with modulo-128 encoding for SABME sessions
Other changes:
* Move or delete macros from include/patty/ax25/macros.h into
include/patty/ax25.h and include/patty/ax25/frame.h
* Move definitions from include/patty/ax25/proto.h to header file
include/patty/ax25.h
* Perform better bounds checking while decoding frames
* Improve frame control printing in src/print.c; display frame
type names, N(R), (NS) sequence numbers, and poll/final bits
