2014-01-24 Corey Minyard <[email protected]>
* ser2net.h, Makefile.am: Move some things into a new
ser2net.h file.
* devcfg.c, controller.c, dataxfer.c, ser2net.c, utils.c: Add the
ser2net.h include file.
* dataxfer.c: Fix some EAGAIN handling.
2014-01-23 Corey Minyard <[email protected]>
* utils.h, readconfig.c, dataxfer.c: Rework the find_xxx
functions to return a strdup of the string.
* dataxfer.c, dataxfer.h, devcfg.h: Remove the dinfo structure
and move the contents into the port structure, and remove the
now empty devcfg.h.
* configure.ac: Minor rework.
2014-01-22 Corey Minyard <[email protected]>
* io.h, devcfg.h, devcfg.c, dataxfer.c, buffer.c, buffer.h: Abstract
the device I/O operations.
* utils.c, utils.h, controller.h, controller.c: Fix some const
correctness issues
* controller.c, controller.h: Add printf-style output.
* dataxfer.h, dataxfer.c, devcfg.h, devcfg.c, io.h, readconfig:
Rework the error and output handling to make it more flexible, so
errors can be output with useful information from the lower
levels.
2013-08-08 Corey Minyard <[email protected]>
* utils.c, utils.h, dataxfer.c, controller.c: Rework the handling
of addresses to work properly with all the return values of
getaddrinfo, and to prefer IPV6 over IPV4 when opening the socket.
This means if you specify a number, it will open the IPV6 ::,port
address first. This was a big cleanup, and moved a lot of the
base socket handling into utils.h.
* dataxfer.c: Rework the stdio handling so it doesn't rely on the
port number in the address, since that is now gone.
* dataxfer.c: Set port->closestr to NULL when freeing it to avoid
a double-free.
* readconfig.c, ser2net.8: Rework the input handling so an IPV6
can be specified as part of the portnum parameter. This was hard
because IPV6 addresses have ':' in them. Basically, if there is a
"," in the port specification, assume that everything from the
beginning of the line to the ':' after the ',' is the port number.
* utils.c, utils.h, dataxfer.c, controller.c: Modified address
handling so that ser2net opens all the addresses returned by
getaddrinfo, not just the first one. That should make things
work correctly in a lot more cases.
2013-08-07 Corey Minyard <[email protected]>
* utils.c, controller.c, dataxfer.c: Return an errno from
scan_tcp_port() so it can return an out of memory error.
* controller.c, controller.h, ser2net.c: Add an out of memory
return code from controller_init().
2013-07-31 Longshine <[email protected]>
* utils.c: Copy input string to a temporary buffer before
calling strtok_r in scan_tcp_port.
2013-07-28 Corey Minyard <[email protected]>
* configure.ac: Move to version 2.9.1. There was an issue with
the configure setup. So autoreconf and redistribute.
2013-07-26 Corey Minyard <[email protected]>
* dataxfer.c: Fix a bug in format strings where hex element (\x)
would have the wrong values for a-f. Pointed out by Galen Seitz.
2013-07-26 Corey Minyard <[email protected]>
* configure.ac: Version 2.9.
2013-07-25 Yegor Yefremov <[email protected]>
* Make RFC2217 signature configurable:
Add '-s' option to configure default signature, that can be
requested via RFC2217 protocol (option 0).
Add per port signature via SIGNATURE keyword.
2013-06-29 Yegor Yefremov <[email protected]>
* dataxfer.c: The baudrate, that will be sent to the client,
was converted twice: first with htonl() and then via copying
to the buffer. As result 38400 was transferred as 6500960000
instead of 6500009600.
2013-05-07 Corey Minyard <[email protected]>
* buffer.c: Add a buffer wrap that was missed, identified by
Brian Rzycki.
2013-03-01 Corey Minyard <[email protected]>
* Makefile.am: Added 'ACLOCAL_AMFLAGS = -I m4' as suggested by
libtoolize.
* configure.in -> configure.ac
* configure.ac: Add 'AC_CONFIG_MACRO_DIR([m4])' as suggested by
libtoolize.
* configure.ac: Version 2.8.
2013-02-28 Corey Minyard <[email protected]>
* dataxfer.c, readconfig.c: Properly handle an empty string passed
as a banner, openstr, or closestr.
2013-01-29 Corey Minyard <[email protected]>
* utils.h, utils.c: Have scan_tcp_port() take the domain.
* dataxfer.c, controller.c: If the socket open fails with
EAFNOSUPPORT, retry the address with IF_INET (IPV4-only). This
way the call will still work even if IPV6 is disabled.
2012-12-19 Corey Minyard <[email protected]>
* README: Add info on how to generate configure and friends.
2012-12-13 Jordi Riera-Babures <[email protected]>, Corey Minyard <[email protected]>
* devcfg.c: Add support for a bunch of high-speed baud rates.
2012-12-07 Corey Minyard <[email protected]>
* utils.c: Change hints.ai_family from AF_INET6 to AF_UNSPEC.
That way it won't force IPV6, but it will return either. I
think that's right.
2012-12-04 Corey Minyard <[email protected]>
* utils.c, utils.h: Modify scan_tcp_port to return the length of
the socket info returned by getaddrinfo().
* controller.c, dataxfer.c: Use the length returned by
scan_tcp_port(), not the size of sockaddr_storage, for the length
of the socket information.
2012-09-26 Corey Minyard <[email protected]>
* configure.in: Move to 2.8-rc3
* dataxfer.c, dataxfer.h, selector.c, selector.h, ser2net.c: Add
clean shutdown handling so locks are properly removed when the
program is killed with SIGINT.
* dataxfer.c: Modify the lock files to be Linux FHS compliant.
2012-09-10 Corey Minyard <[email protected]>
* dataxfer.c: Fix a bug reported by Jan-Benedict Glaw, where
port->dinfo.openstr may be NULL, but srdup is called on it
without checking. Add a check.
2012-07-23 qchats lee <[email protected]>
* dataxfer.c: My change for this did not match Qchats' change,
so fix that.
* utils.c: Fix the write_full() function to handle the return
result properly; the parenthesis in the if statement ended
in the wrong place.
2012-07-22 qchats lee <[email protected]>
* dataxfer.c: Add a missing ")" after the "OPEN(..." when
header tracing.
2012-04-18 Corey Minyard <[email protected]>
* buffer.c, buffer.h, Makefile.am: Added a new type and set of
operations for buffer handling. This simplifies and allows
abstraction of other parts of the code.
* dataxfer.c, telnet.c, telnet.h, controller.c: Switch
out_telnet_cmd and associated parts to be the new buffer type.
* dataxfer.c: Switch the banner over to the new buffer type.
* dataxfer.c: Consolidate banner and filename string handling.
Note that there was an issue with \s, as it was something
different in banners and filenames. Added new options, \S (for
seconds) and \B (for serial port parameters) to resolve this
issue, and \s is backwards compatible but deprecated.
* ser2net.8, ser2net.conf: Since the consolidated banner/filename
processing allows all the \<x> options to be available for both
banners and filenames, rework the documentation.
* dataxfer.c: Convert the main I/O buffers for data transfer to
the new buffer type.
* devcfg.h, devcfg.c, readconfig.c, utils.h: Added a
new OPENSTR and CLOSESTR option for the configuration file. These
are strings that will be transmitted to the device when a port is
opened and/or closed.
* ser2net.8, ser2net.conf: Added docs for the OPENSTR and CLOSESTR
options.
* dataxfer.c: Handle the new OPENSTR and CLOSESTR options. This
required adding a new state, PORT_CLOSING, for the tcp_to_dev_state
to say that the port is closing but data is going out, and splitting
up the shutdown handling.
* utils.c: Fixed a bug that cause the "port in use" error on the
TCP connection to be printed strangely.
* dataxfer.c: Since the banner handling no longer depends on being
able to put the whole banner in the output buffer, reduce the port
buffer sizes to 64 bytes to reduce memory usage
* selector.c: maxfd was not initialized for a selector, fix that.
* configure.in: Move to 2.8-rc2.
2012-04-04 Corey Minyard <[email protected]>
* dataxfer.c: Turn on the tcp write handler at first for raw
sockets, otherwise the banner won't come out till some data
comes in on the port.
2012-04-03 Corey Minyard <[email protected]>
* devcfg.c: Add 600 baud.
2012-03-27 Corey Minyard <[email protected]>
* ser2net.c, readconfig.c, ser2net.h, controller.c, ser2net.conf:
Add a method to specify the control port in the ser2net config
file.
* dataxfer.c, controller.c: Add SO_KEEPALIVE to socket connections
so the connection will drop if the other end just goes away.
* configure.in: Move to 2.8-rc1.
2011-08-12 Corey Minyard <[email protected]>
* dataxfer.c: Fix some unaligned write issues in telnet options.
* dataxfer.c: Fix some signed/unsigned comparison issues and
a typo.
2011-06-22 Corey Minyard <[email protected]>
* utils.h, utils.c, controller.c, dataxfer.c: Fix some warnings
about the write() return value not being checked. These were
almost all cases where a failure didn't matter (tracing), except
for writing the pid file, where it should have been a handled
failure.
* dataxfer.c: Cleaned up some style issues in the UUCP locking code.
* ser2net.c: Fixed a warning about not checking the chdir() return
code, and added some improved logging information to syslog.
2010-03-11 Mats Erik Andersson <[email protected]>,
Corey Minyard <[email protected]>
* controller.c, dataxfer.c, utils.c, utils.h: Add IPV6 address
compatibility.
2009-11-12 Corey Minyard <[email protected]>
* ser2net.spec, ser2net.spec.in: Fix the version in the spec
file to be updated automatically.
2009-11-12 Philip Gwyn
* dataxfer.c, devcfg.c, devcfg.h, ser2net.8: Add the ability to
dump trace files in a binary format with timestamps.
2009-11-03 Corey Minyard <[email protected]>
* configure.in: Move version to 2.7 for release.
2009-10-23 Corey Minyard <[email protected]>
* configure.in: Move to 2.7-rc3.
* dataxfer.c, devcfg.c, devcfg.h, ser2net.h: Modified the tb=
directive to work separately from tw= and tr=, so you can do all
three at the same time independently.
* readconfig.c: Improved an error report.
2009-10-22 Corey Minyard <[email protected]>
* ser2net.c: Set up routing errors to stderr before reading the
config so config errors come out properly to stdout.
* ser2net.8, ser2net.conf: Fix the documentation, it's tw=, not
tw: for the tracefile stuff.
* configure.in: Move to 2.7-rc2.
2009-10-15 Corey Minyard <[email protected]>
* dataxfer.c, devcfg.c, readconfig.c, ser2net.8, ser2net.conf: Add
the ability to trace data read written to trace files.
2009-07-19 Geoff Simmons <[email protected]>
* ser2net.conf: Some documentation cleanup, added missing docs
for the timeout parameter.
* README - Minor doc cleanup.
2009-07-15 Corey Minyard <[email protected]>
* configure.in: Move to version 2.6.
2009-06-30 Corey Minyard <[email protected]>
* dataxfer.c, devcfg.c, devcfg.h, readconfig.h, utils.h: Add the
a TRACEFILE option to trace all I/O to a file., and separate
out the defconfig into a separate structure to avoid passing a
boatload of things to the config.
2009-06-30 Sebastian Andrzej Siewior <[email protected]>
* controller.c: Fix use after free in controller
The controller will use its dynamically allocated data after it
got free() in error path. What we see in syslog is:
Jun 30 10:26:38 consrv3 ser2net[3073]: read error for
controller port: Connection reset by peer
Jun 30 10:26:39 consrv3 ser2net[3073]: The tcp write for
controller had error: Bad file descriptor
The first error is "legal" because the destination decided to
close its socket a little to early than expected. The second
error is already bad because it tries to use already
deallocated fd. Later we segfault.
2007-11-16 Corey Minyard <[email protected]>
* configure.in: Move to version 2.5.
2007-11-16 Harry Flick, Corey Minyard <[email protected]>
* devcfg.c, devcfg.h, dataxfer.c, ser2net.conf, ser2net.8: Allow a
"NOBREAK" option to disable automatically messing with the break
operations on the serial port. Useful for systems with a broken
break.
2007-11-16 Robert Edmonds <[email protected]>,Corey Minyard <[email protected]>
* ser2net.c, ser2net.8: Add a '-P' option to specific that a
pidfile be created.
2007-05-03 Corey Minyard <[email protected]>
* dataxfer.c: Change the rfc2217 signature response code
from 0 to 100. Best guess on what this should be, as the
RFC doesn't give the correct value and says "text".
2007-04-26 Corey Minyard <[email protected]>
* dataxfer.c: Disable the Nagle algorithm (enable TCP_NODELAY) on
the TCP ports to avoid long delays on short pieces of data.
* configure.in: Move to version 2.4.

"sys/ioctl.h".
2005-10-20 Corey Minyard <[email protected]>
* dataxfer.c: Fixed a problem with rfc2217 stop bit size setting.
It was interpreting the value of "3" as 2 stop bits, but 3 is for
1.5 stop bits, and 2 is for 2 stop bits.

char problems.
* dataxfer.c: ditto
* telnet.c: ditto
2005-08-25 Corey Minyard <[email protected]>

* configure.in: Moved to version 2.1.
* dataxfer.c: Have the telnet option responses use the 1xx
responses to the com port control options. I believe this is
wrong, but it is consistent with other products already in the
field.

use of Cisco IOS baud rates instead of RFC 2217 ones, by command
option.
