Implement an APRS-IS interface type which is capable of receiving all
APRS-IS traffic which can be represented in AX.25 frames; currently,
there are no provisions for handling extended features such as
non-numeric SSIDs, nor a client nor server which facilitate direct
APRS-IS communication. Presently, APRS-IS traffic cannot be sent from
this interface.
Changes:
* Add patty_ax25_aprs_is driver type in src/aprs_is.c
* Implement 'aprs-is' interface configuration type in bin/if.c; make
separate, smaller state machines for handling base interface
config, KISS, and APRS-IS interface config
Changes:
* Implement patty_ax25_if_driver type, providing a vtable with
pointers to methods implementing an AX.25 interface PHY
* Implement patty_ax25_if_name() to return a pointer to the name
string of an AX.25 interface
* Decouple patty_kiss_tnc from src/if.c using patty_ax25_if_driver
* Remove port input/output arguments from patty_kiss_tnc_send()
and patty_kiss_tnc_recv(), respectively; use 0 as the default,
but keep the port argument in patty_kiss_frame_send()
* Implement patty_ax25_if_fd() to return file descriptor backing a
PHY; use this rather than patty_kiss_tnc_fd() in src/server.c to
further decouple interfaces from their implementation
* Remove 'enum patty_ax25_if_type' type; refactor constructor
patty_ax25_if_new() to no longer take this as an argument, but
rather a patty_ax25_if_driver to use to instantiate the PHY
with the information pointer passed
* Break out patty_kiss_tnc code from src/kiss.c into src/tnc.c,
leaving only patty_kiss_frame_send() in the original; this is
needed to prevent a cyclic dependency within patty_ax25_sock and
other areas
* Rename patty_bin_if_config() to patty_bin_if_create(); a separate
patty_bin_if_config() will likely be created later as necessary
to change an existing interface
* Split PHY-specific interface configuration code into separate
delegates in bin/if.c
* Implement usage of patty_error to better capture internal error
states not currently representable with semantic error numbers
while configuring and instantiating PHYs
* Pass patty_error object to patty_bin_kiss_config() to receive
detailed error information
Initial implementation of bin/ax25dump.8 man page
Other changes:
* Make consistent mention of [tioarg ...], rather than tioflags
or tioargs
* Small bin/Makefile improvements to assist in installing man
pages for different manual sections
Changes:
* Move network interface configuration logic from bin/pattyd.c to
bin/if.c; implement a more robust state machine
* Move KISS TNC configuration code from bin/pattyd.c to bin/kiss.c
* Ensure configuration file name, line number, and erroneous part
of an expression are clearly indicated upon failure
Other changes:
* Improve bin/Makefile to rebuild objects when accompanying header
files change
* Refer to HEADERS_SUBDIR, not HEADER_SUBDIR, in Makefiles
Changes:
* Move examples/ax25dump.c to bin/ax25dump.c; deprecate the other
similar program, examples/decode.c
* Implement support for reading KISS frames from a file, much in
the manner of examples/decode.c
Changes:
* Implement src/conf.c, patty_conf_read(), to read a configuration
file to support a OpenBSD-style configuration file format
* Implement bin/pattyd.c to use patty_conf_read() to read a
configuration file and apply its settings to a patty_daemon
object as it is read; also implement a --standalone|-s flag to
allow the user to start a patty server without having to write
a configuration file
* Refactor patty_daemon_if_add() to accept a patty_ax25_if object;
this is necessary as bin/pattyd.c needs to be able to validate
the addresses given in a configuration file 'if' statement
* Refactor patty_ax25_server_new() to no longer accept a client
socket path; instead, patty_ax25_server_start() now accepts the
client socket path
* Remove the client socket 'path' member from patty_ax25_server in
src/server.c
* Refactor patty_kiss_tnc_new() to accept only one argument, a
patty_kiss_tnc_info object containing flags and settings needed
to open a device, use an existing file descriptor, or change
termios settings as appropriate
* Remove patty_kiss_tnc_new_fd(), as its functionality now exists
in patty_kiss_tnc_new() itself
* Add a 'flags' field to patty_kiss_tnc_info; use this bit field
to determine whether a path or file descriptor is provided by
the caller
* Make patty_ax25_if_new() accept an interface name argument, as
names are explicitly required when declaring new interfaces in
configuration files
* Make patty_kiss_tnc_new() able to accept /dev/ptmx as a device
name, regardless of whether this character device exists on a
given platform; when provided, a pseudo TTY pair is allocated
with openpty()
* Refactor examples/ax25dump.c to use the new patty_kiss_tnc_new()
calling convention
* Refactor examples/decode.c to use the new patty_kiss_tnc_new()
calling convention
* Remove examples/daemon.c in favor of bin/pattyd.c
* Rename examples/patty.conf to examples/pattyd.conf; modify to
provide values which would actually function
