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
Improved portability in ./configure to add detection for various smaller
items, such as headers necessary for openpty(3), et cetera; improve
overall script structure
Use openpty(3) to open PTYs, to achieve compatibility with OpenBSD as
posix_openpty() returns a file descriptor which does not block on
read() nor select()
Fix bug in patty_ax25_if_addr_add() wherein, due to a typo of memcpy()
rather than memcmp(), the function would never fail to add an address
to an interface, even if it already exists on the interface
Changes:
* Add argument to patty_kiss_tnc_new(), patty_kiss_tnc_new_fd(),
a pointer to patty_kiss_tnc_info, to allow specifying baud and
flow control
* Rework patty_ax25_if_kiss_tnc_info to hold patty_kiss_tnc_info as
a hack to allow instantiating a KISS TNC-based network interface
with desired baud and flow control
Implement src/daemon.c to provide a high level method to instantiate a
patty server
Changes:
* Refactor src/server.c, src/route.c, src/if.c methods which accept
callsign arguments to use a patty_ax25_addr pointer instead; this
has significantly reduced the number of redundant calls to
patty_ax25_pton()
* Decouple patty_ax25_addr from patty_ax25_if_info types when
creating new interfaces with patty_ax25_if_new(); instead, take a
separate patty_ax25_addr argument
* Split patty_ax25_server_run() into the following methods:
- patty_ax25_server_start()
- patty_ax25_server_stop()
- patty_ax25_server_event_handle()
This is intended to allow possible integration into other event
loops.
* Implement src/daemon.c to allow quick instantiation of a server,
interfaces, and routes, and to encapsulate the setting of
configuration variables; callsigns and interface names are handled
as character strings
* Rename examples/server.c to examples/daemon.c; reimplement in
terms of the patty_daemon code
*
Rename patty_ax25_sock.rx_buf to io_buf, as the buffer is not used for
receiving frames from an interface, but rather from reading local data
to write to a remote peer
Other changes:
* Fix issue wherein patty_ax25_sock.n_maxlen_tx was not used for
reading local data when sending I frames
Changes:
* Ensure Timer T1 is stopped when Timer T3 is active
* Ensure Timer T1 is started when an acknowledgement from the peer
does not acknowledge all I frames previously sent
Make patty_ax25_sock_ack() return 1 if N(R) = V(A), to provide a
convenient means of verifying that an acknowledgement from the peer is
at least valid for current sequence variables, even if no new frames are
acknowledged; patty_ax25_sock_ack_pending() can always be used to
determine when frames are still pending acknowledgement
