   1 lldpd (1.0.0)
   2   * Changes:
   3     + Chassis ID can be set to an arbitrary value with "configure system
   4       chassisid".
   5   * Fix:
   6     + Ensure chassis-related changes are propagated immediately.
   7
   8 lldpd (0.9.9)
   9   * Changes:
  10     + lldpcli can now display local interfaces with LLDP data sent on
  11       each of them ("show interfaces").
  12     + As Dot3 PD device, echo back allocated value from PSE device.
  13   * Fix:
  14     + Don't remove interfaces when they are released from a bridge.
  15     + Don't use "expect stop" with Upstart. It's buggy.
  16
  17 lldpd (0.9.8)
  18   * Changes:
  19     + "Station" capability is only set if no other bit is set.
  20     + Use ethtool to get permanent address for bonds and teams. This
  21       might provide different results than the previous method. Some
  22       devices may still use the previous method.
  23     + Don't run ethtool as root. Kernels older than 2.6.19 won't get
  24       link information anymore.
  25     + Add "configure system hostname ." option to not use a FQDN
  26       for system name.
  27     + Add "-f json0" to provide a more regular/machine-parsable output
  28       to JSON output, even when not compiled with --enable-json0.
  29   * Fixes:
  30     + Handle team interfaces like a bond. Real MAC address cannot be
  31       retrieved yet.
  32
  33 lldpd (0.9.7)
  34   * Changes:
  35     + Attach remote TTL to port instead of chassis.
  36     + JSON support is now built-in and unconditionally enabled. Use
  37       --enable-json0 to keep the pre-0.9.2 json-c format.
  38     + When logging to syslog and daemonizing, don't log to stderr.
  39     + vxlan interfaces are now ignored as they are multi-point interfaces.
  40     + Maximum number of neighbors for an interface is increased from 4 to 32.
  41
  42 lldpd (0.9.6)
  43   * Changes:
  44     + Add a compile-time option to restore pre-0.9.2 JSON format (when
  45       using json-c). Use `--enable-json0` to enable this option.
  46     + Support for newer ethtool interface on Linux
  47       (ETHTOOL_GLINKSETTINGS) and additional speed settings.
  48     + Current MAU type is displayed even when autoneg is off.
  49     + Increase netlink receive buffer by default. Can be changed at
  50       compile-time through ./configure.
  51   * Fixes:
  52     + Correctly parse LLDP-MED civic address when the length of the
  53       TLV exceeds the length of the address.
  54     + Fix 100% CPU on some rare error condition.
  55     + Fix lost timer when an interface is enslaved on Linux.
  56
  57 lldpd (0.9.5)
  58   * Changes:
  59     + More Ethernet media supported. However, RFC4836 is quite
  60       out-of-date with respected to 10G+ speeds, bringing some
  61       inaccuracies.
  62     + Directly get media information for an interface without using
  63       the privileged process.
  64     + LLDP-MED capability TLV is not sent when LLDP-MED is not enabled,
  65       even if other LLDP-MED TLV are present.
  66   * Fixes:
  67     + Compilation fix with older versions of GCC.
  68     + Don't use ethtool at all to get real MAC address for enslaved
  69       devices (always use /proc).
  70
  71 lldpd (0.9.4)
  72   * Changes:
  73     + Make lldpd accepts a `-p` option to specify the PID file.
  74     + Ability to change multicast MAC address to two additional values
  75       to reach customer bridges.
  76     + lldpcli will now display chassis TTL when detailed view is enabled.
  77   * Fixes:
  78     + Fix setting of local value for port ID.
  79     + Fix compilation with BSD make.
  80     + Ensure lldpcli returns an error code on invalid commands.
  81
  82 lldpd (0.9.3)
  83   * Changes:
  84     + Do not rely on support of constructors for liblldpctl.
  85     + Always log to stderr (even in addition to syslog).
  86     + `lldpcli watch` accepts a limit on the number of received events.
  87   * Fixes:
  88     + `lldpcli -f {xml,json} watch` should work now.
  89     + Consider `veth` interfaces as physical interfaces.
  90
  91 lldpd (0.9.2)
  92   * Changes:
  93     + Ability to add/remove/replace custom TLV from lldpcli.
  94     + LLDP-MED capabilities are displayed differently in lldpcli.
  95     + Limit the maximum depth (5) when trying to apply a VLAN.
  96     + Change JSON output format when using json-c to match Jansson
  97       output.
  98     + Integration tests for the major parts of lldpd, including use of
  99       address and leak sanitizer.
 100   * Fixes:
 101     + LLDP-MED POE TLV are now displayed in lldpcli.
 102     + Ignore lower link when it is in another namespace.
 103     + Fix various problems with interfaces being enslaved.
 104     + Fix a memory leak when modifying port-related settings.
 105
 106 lldpd (0.9.1)
 107   * Changes:
 108     + Rework packaging for OS X to make it work with El Capitan. To
 109       simplify a bit, it is not possible anymore to build fat
 110       binaries. Latest version of OS X supporting 32bit was 10.6.
 111   * Fixes:
 112     + By default, when using port alias as description, use port name
 113       as port ID.
 114     + Miscellaneous fixes with netlink cache.
 115     + Ensure large netlink messages can be received.
 116
 117 lldpd (0.9.0)
 118   * Changes:
 119     + Don't rely on libnl3 for netlink. Reuse the previous code and
 120       implement a lighweight cache.
 121
 122 lldpd (0.8.0, never released)
 123   * Changes:
 124     + PIE is now disabled by default. It's too difficult to reliably
 125       detect if it works. Use --enable-pie to enable it.
 126     + Retrieve the permanent MAC address of an interface through
 127       ethtool for Linux if /proc/net/bonding is not available.
 128     + Running lldpd with "-d" will keep the process in foreground but
 129       logs will still go to syslog. To log to the console, add at
 130       least one "-d".
 131     + Fix minimal kernel version to 2.6.39. Add a runtime warning when
 132       this is not the case.
 133     + Remove old bridge code (the one using ioctl).
 134     + Don't discard down interfaces. Notably, this enables us to keep
 135       their specific configuration if any.
 136     + For Linux, switch to libnl3. Be aware of the licensing issues in
 137       case of static linking.
 138     + Introduce the notion of default local port. New interfaces will
 139       use it as a base. This allows setting various MED stuff.
 140     + Provide an apparmor profile (untested).
 141   * Fixes:
 142     + Fix a buffer overflow when receiving a too large management
 143       address TLV. Unless hardening has been disabled, this overflow
 144       cannot be used for arbitrary code execution.
 145     + Update LLDP-MED policy L2 priority values to match
 146       802.1Q-2005. This may be a breaking change.
 147
 148 lldpd (0.7.17)
 149   * Fixes:
 150     + Fix the way libevent configure is called.
 151     + Fix an infinite loop when using veth on Linux 4.1+ kernels.
 152     + Make CDP advertise the appropriate kernel name as platform,
 153       not just "Linux".
 154
 155 lldpd (0.7.16)
 156   * Changes:
 157     + For Linux, 2.6.32 is now the minimal required kernel. When using
 158       an older kernel, use `--enable-oldies`.
 159     + For Linux, use netlink to retrieve information about bridges,
 160       VLAN and bonds. The code was contributed by Cumulus Networks.
 161     + Use symbol versioning for liblldpctl.so.
 162     + Ability to get local chassis information with "show
 163       chassis".
 164     + The library also has the same ability with the
 165       `lldpctl_get_local_chassis()` function. It is also possible to
 166       get a chassis atom from a port with `lldpctl_k_port_chassis`
 167       key. This is now the preferred way to retrieve chassis related
 168       information.
 169   * Fixes:
 170     + Fix build on OS X.
 171     + Accept "language" when configuring MED location as a civic address.
 172
 173 lldpd (0.7.15)
 174   * Changes:
 175     + Optional features can be configured with "auto" to autodetect if
 176       they are usable. This is the default value for JSON and XML support.
 177     + Ability to send and decode custom/unknown TLV. Thanks to Alexandru
 178       Ardelean.
 179     + Modify checksum function. While this should be strictly
 180       equivalent, if you notice CDP packets not accepted anymore, this
 181       change is the first culprit.
 182
 183 lldpd (0.7.14)
 184   * Changes:
 185     + Shutdown LLPDU are sent on MSAP change and when lldpd exits.
 186     + When an exact IP is provided as a management pattern, use it
 187       unconditionally.
 188     + Ability to set port ID and description to an arbitrary value,
 189       thanks to Alexandru Ardelean.
 190   * Fixes:
 191     + Incorrect boundary check when decoding management address and
 192       protocol identity may lead to lldpd crash when processing
 193       malformed LLDPDU.
 194     + Many edge cases where lldpd was leaving hanging processes after
 195       crashing.
 196
 197 lldpd (0.7.13)
 198   * Fixes:
 199     + Unbreak customization of Unix socket path from command line.
 200
 201 lldpd (0.7.12)
 202   * Changes:
 203     + Interface pattern, management pattern, system description,
 204       system platform and system hostname can be unconfigured to their
 205       default values.
 206   * Fixes:
 207     + Don't complain when parsing a commented line.
 208     + Correctly persist configuration changes for "system interface
 209       promiscuous", "system interface description" "med fast-start
 210       enable", "pause" and "resume".
 211     + Fix listening on bond devices for old kernels (< 2.6.27).
 212
 213 lldpd (0.7.11)
 214   * Changes:
 215     + Ship bash and zsh completion.
 216     + Abort when some command-line options are repeated.
 217   * Fixes:
 218     + Handle correctly read failures in liblldpctl.
 219
 220 lldpd (0.7.10)
 221   * Changes:
 222     + Ability to set promiscuous mode to work around bugs of some
 223       switches encapsulating LLDP frames inside 802.1Q frames.
 224     + JSON support for lldpcli can use json-c instead of jansson,
 225       thanks to Michel Stam.
 226   * Fixes:
 227     + Fix checksum computation for Cisco CDP.
 228     + Fix ability to disable LLDP.
 229     + Fix seccomp sandbox, thanks to Patrick McLean.
 230
 231 lldpd (0.7.9)
 232   * Changes:
 233     + Default location for chroot, socket and PID are now configurable
 234       in `./configure`. The default location is based on the value of
 235       `runstatedir` which in turn may be based on the value of
 236       `localstatedir` which defaults to `/usr/local/var`. Therefore,
 237       to get the previous locations, lldpd should be configured with
 238       `./configure --localstatedir=/var`.
 239     + Add support for shutdown LLDPU.
 240     + Ability to configure IP management pattern from lldpcli.
 241     + Ability to choose what port ID should be (MAC or interface name).
 242   * Fixes:
 243     + Fix `configure system bond-slave-src-mac-type local`. Also use
 244       it as default.
 245
 246 lldpd (0.7.8)
 247   * Changes:
 248     + Android support
 249     + Add the possibility to disable privilege separation (lower
 250       memory consumption, lower security, don't do it).
 251     + Interfaces can now be whitelisted. For example, *,!eth*,!!eth1
 252       is a valid pattern for all interfaces except eth ones, except
 253       eth1. Moreover, on exact match, an matching interface
 254       circumvents most sanity checks (like VLAN handling).
 255     + Ability to override the hostname.
 256   * Fixes:
 257     + Don't hard-code default values for system name, system
 258       description and port description. When the field is not present,
 259       just don't display it.
 260     + Fix lldpcli behaviour when suid.
 261     + On OSX, don't use p2p0 interfaces: it would break WLAN.
 262     + Fix SNMP support on RHEL.
 263
 264 lldpd (0.7.7)
 265   * Changes:
 266     + Use a locally administered MAC address or an arbitrary one
 267       instead of null MAC address for bond devices on Linux. This is
 268       configurable through `lldpcli`.
 269     + Add support for "team" driver (alternative to bond devices).
 270     + Preliminary support for DTrace/systemtap.
 271     + Preliminary support for seccomp (for monitor process).
 272     + Setup chroot inside lldpd instead of relying on init script.
 273   * Fixes:
 274     + Various bugs related to fixed point number handling (for
 275       coordinates in LLDP-MED)
 276     + Fix a regression in how MAC address of an enslaved device is
 277       retrieved.
 278
 279 lldpd (0.7.6)
 280   * Changes:
 281     + Provide a way to build packages for OSX.
 282     + Add an option to update interface description with neighbor name.
 283   * Fixes:
 284     + Compilation fix for OSX 10.6.
 285
 286 lldpd (0.7.5)
 287   * Fixes:
 288     + Segfault while tokenizing in lldpcli.
 289
 290 lldpd (0.7.4)
 291   * Fixes:
 292     + Segfault in lldpcli.
 293     + Memory leak in liblldpctl when using a custom log handler.
 294     + Fix some unaligned memory accesses.
 295     + Fix frame reception on OpenBSD.
 296   * Changes:
 297     + Allow to configure hold value from lldpcli (and hence the TTL).
 298     + Allow to configure pattern for valid interfaces from lldpcli.
 299     + Allow to override system description from lldpcli.
 300     + Display the neighbor connected as the process title (or the
 301       number of connected neighbors).
 302
 303 lldpd (0.7.3)
 304   * Changes:
 305     + DragonFly BSD support.
 306     + Solaris support (incomplete).
 307     + LLDP-MED fast start support (thanks to Roopa Prabhu).
 308     + Provide global statistics through "show statistics summary"
 309       command (thanks to Roopa Prabhu).
 310   * Fixes:
 311     + Fix IPv4/IPv6 address discovery in Linux.
 312
 313 lldpd (0.7.2)
 314   * Changes:
 315     + lldpd can be configured through /etc/lldpd.conf and
 316       /etc/lldpd.d. All commands accepted by lldpcli are accepted.
 317     + Lock BPF interfaces before handing them to chrooted process on
 318       BSD.
 319     + Limit the number of neighbors for each port to 4 (per protocol).
 320     + Force CDPv2 protocol with argument `-ccc`.
 321     + Provide port statistics through "show statistics" command
 322       (thanks to Roopa Prabhu).
 323   * Fixes:
 324     + Driver whitelisting is done before checking if an interface has
 325       a lower interface in Linux.
 326     + Expire remote ports and chassis in a timely manner.
 327
 328 lldpd (0.7.1)
 329   * Changes:
 330     + Mac OS X support, sponsored by Xcloud, Mac cloud server hosting
 331       provider. http://xcloud.me/
 332     + Upstart and systemd support.
 333     + Remove Unix socket when there is no process listening.
 334
 335 lldpd (0.7.0)
 336   * Changes:
 337     + FreeBSD support.
 338     + OpenBSD support.
 339     + NetBSD support.
 340     + Detect interface changes.
 341     + CLI for lldpctl: lldpcli.
 342     + Allow to disable LLDP protocol (with `-ll`). In this case, the
 343       first enabled protocol will be used when no neighbor is detected.
 344     + Allow to filter debug logs using tokens. Add more debug logs.
 345     + lldpctl can now output JSON.
 346     + Use netlink to gather interface information on Linux.
 347     + Don't use ioctl for bridges anymore on Linux. The configure
 348       option `--enable-oldies` allow to reenable their uses for
 349       systems not supporting sysfs.
 350
 351 lldpd (0.6.1)
 352   * Changes:
 353     + Provide liblldpctl.so, a library to interface with lldpd. The
 354       documentation is provided through Doxygen. See src/lib/lldpctl.h
 355       which contains all the exported functions.
 356     + Make lldpctl uses liblldpctl.so.
 357     + Add a "watch" option to lldpctl to monitor neighbor changes.
 358     + Add the possibility to display the current configuration of
 359       lldpd with lldpctl. Also add the possibility to reset the
 360       current transmit delay.
 361
 362 lldpd (0.6)
 363   * Changes:
 364     + Allow lldpctl to display hidden ports.
 365     + Add a switch to specify interfaces to use to get chassis ID.
 366     + Support for multiple management addresses and IPv6 management
 367       addresses. Contributed by João Valverde.
 368     + Switch to libevent. See README.md for details.
 369     + Partial rewrite of the SNMP part. Less code.
 370     + Unit tests for SNMP.
 371     + Major rewrite of the protocol between lldpd and lldpctl. Less
 372       code.
 373   * Fixes:
 374     + Several small SNMP fixes (discovered by unit tests).
 375
 376 lldpd (0.5.7)
 377  * Fixes:
 378     + Configure issue with NetSNMP and some linkers
 379     + Fix infinite loop for the receive part: on certain conditions,
 380       lldpd will stop sending packets and stop updating local data.
 381
 382 lldpd (0.5.6)
 383   * Changes:
 384     + Send and receive native VLAN TLV with CDP
 385     + Add a whitelist for some drivers (currently: dsa and veth)
 386   * Fixes:
 387     + Compilation issues with NetSNMP 5.7 (and with earlier versions too)
 388     + Small optimization of BPF filter
 389
 390 lldpd (0.5.5)
 391   * Changes:
 392     + Support for PPVID and PI Dot1 TLV, thanks to Shuah Khan.
 393     + Extend whitelist with possibility to blacklist.
 394   * Fixes:
 395     + Key/value output was incorrect when a dot was present in
 396       interface names. This is fixed but it is preferable to use XML
 397       output since the parsing is more difficult in this case.
 398     + Only grab DMI information once. Only uses DMI for x86 platform.
 399     + Padding issues with socket protocol. This introduces a change in
 400       the socket protocol!
 401     + Fix a segfault when neither /etc/os-release nor lsb_release
 402       are available.
 403
 404 lldpd (0.5.4)
 405   * Changes:
 406     + Get OS information from /etc/os-release if available. Patch from
 407       Michael Tremer.
 408     + Add a flag to specify which interfaces lldpd should listen to.
 409
 410 lldpd (0.5.3)
 411   * Changes:
 412     + Handle Dot3 POE-MDI TLV (802.3af and 802.3at).
 413     + Allow to set Dot3 POE-MDI from lldpctl.
 414   * Fixes:
 415     + Allow root to change configuration of lldpd when lldpctl has suid set.
 416
 417 lldpd (0.5.2)
 418   * Changes:
 419     + More flexible smart mode and new default. Manual page has been updated.
 420     + Add a "receive-only" mode with "-r" switch.
 421
 422 lldpd (0.5.1)
 423   * Changes:
 424     + Allow to force a protocol even when no peer for this protocol is
 425       detected.
 426     + Add a smart mode that allows to discard bogus port information,
 427       for example CDP packets that are flooded through a switch that
 428       does not support CDP.
 429     + Allow to set LLDP-MED network policy from lldpctl, thanks to a patch from
 430       Philipp Kempgen.
 431     + Allow to set LLDP-MED POE-MDI from lldpctl.
 432     + Add a summary of available options in "lldpd -h" and "lldpctl -h",
 433       thanks to a patch from Jorge Boncompte.
 434     + Add a new output (keyvalue) for lldpctl.
 435     + Listen on VLAN using an appropriate BPF filter, VLAN
 436       decapsulation. Older "listen on vlan" feature is discarded. See
 437       README for more information on the new feature.
 438     + Use output of lsb_release if available for system description.
 439   * Fixes:
 440     + Ignore interface with no queue. It should filter out interfaces
 441       like "vnet0" that would fail if we try to send something on them.
 442     + Don't check CDP checksums (not really a fix but it appears that
 443       Cisco checksum have some difficult corner cases).
 444
 445 lldpd (0.5.0)
 446   * Changes:
 447     + lldpd can now handle several systems on the same port. This
 448       modification also allows to speak to a switch using CDP and LLDP
 449       for example.
 450     + The way that lldpd gathers information for each port has been
 451       abstracted. This should allow to support more systems (BSD for
 452       examples) or switch cores in the future. Sending/receive support
 453       is also abstracted.
 454     + Add "-k" switch to avoid to emit too much information on running
 455       kernel.
 456     + Support of ifAlias with kernel >= 2.6.28
 457     + Lot of portability stuff. lldpd can now be compiled on RHEL
 458       2.1. Still Linux-only though.
 459     + Add an option to specify AgentX socket (-X).
 460     + Add some unit tests
 461     + lldpctl has been reworked; it is now able to output data in XML
 462       format for easier parsing. Patches were provided by Andreas
 463       Hofmeister.
 464   * Fixes:
 465     + Fix EDP VLAN handling
 466     + Silent warnings about bridge stuff.
 467     + Copy /etc/localtime into chroot before starting lldpd daemon to
 468       ensure correct timestamps for logs.
 469
 470 lldpd (0.4.1)
 471   * Fix EDP handling when there is no VLAN
 472   * Fix CDP version to not always be 1
 473   * Misc fix:
 474      + incorrect number of arguments for a LLOG_INFO call
 475      + fix SNMP last change in case this change occurs before start time
 476
 477 lldpd (0.4)
 478   * Rewrite of packet builder and parser to be able to cope with
 479     architecture that cannot do unaligned read. For decoder, we don't
 480     cast structures any more since they can be unaligned. For encoder,
 481     we use memcpy through the use of macro that build packets step by
 482     step.
 483
 484 lldpd (0.3.2)
 485   * Fix LLDP-MED support
 486
 487 lldpd (0.3.1)
 488   * Misc fixes, including memory leaks
 489
 490 lldpd (0.3)
 491   * Initial support of LLDP-MED
 492   * Fix for bridge detection (don't send bridge ioctl on random interfaces)
 493   * For bonded devices, get the real hardware address. For inactive
 494     slaves, transmit using a random MAC address.
 495
 496 lldpd (0.2.1)
 497   * Fix a syntax error in manual page
 498   * Fix open() calls
 499
 500 lldpd (0.2)
 501   * Add privilege separation
 502   * Add FDP support
 503   * Support CDP encapsulated into native VLAN
 504   * Various fixes
 505
 506 lldpd (0.1)
 507   * Initial release
