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  35       out-of-date with respected to 10G+ speeds, bringing some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

 447   * Fix CDP version to not always be 1
 448   * Misc fix:
 449      + incorrect number of arguments for a LLOG_INFO call
 450      + fix SNMP last change in case this change occurs before start time
 451
 452 lldpd (0.4)
 453   * Rewrite of packet builder and parser to be able to cope with
 454     architecture that cannot do unaligned read. For decoder, we don't
 455     cast structures any more since they can be unaligned. For encoder,
 456     we use memcpy through the use of macro that build packets step by
 457     step.
