   1 lldpd (1.0.2)
   2   * Changes:
   3     + On Linux, the monitor process will now drop its privileges
   4       instead of running as root. It will keep CAP_NET_RAW,
   5       CAP_NET_ADMIN and CAP_DAC_OVERRIDE capabilities.
   6     + Support for CDP PD PoE (with negotiation). Thanks to Gustav
   7       Wiklander.
   8
   9 lldpd (1.0.1)
  10   * Fix:
  11     + Use "mkdir -p" instead of "mkdir" in systemd unit.
  12
  13 lldpd (1.0.0)
  14   * Changes:
  15     + Chassis ID can be set to an arbitrary value with "configure system
  16       chassisid".
  17     + Port description can be overriden directly with "configure lldp
  18       portdescription".
  19     + Command "configure system interface permanent" enables one to
  20       specify a pattern for interfaces to be kept in memory even when
  21       they are removed from the system.
  22   * Fix:
  23     + Ensure chassis-related changes are propagated immediately.
  24     + Ensure management address change is correctly detected.
  25
  26 lldpd (0.9.9)
  27   * Changes:
  28     + lldpcli can now display local interfaces with LLDP data sent on
  29       each of them ("show interfaces").
  30     + As Dot3 PD device, echo back allocated value from PSE device.
  31   * Fix:
  32     + Don't remove interfaces when they are released from a bridge.
  33     + Don't use "expect stop" with Upstart. It's buggy.
  34
  35 lldpd (0.9.8)
  36   * Changes:
  37     + "Station" capability is only set if no other bit is set.
  38     + Use ethtool to get permanent address for bonds and teams. This
  39       might provide different results than the previous method. Some
  40       devices may still use the previous method.
  41     + Don't run ethtool as root. Kernels older than 2.6.19 won't get
  42       link information anymore.
  43     + Add "configure system hostname ." option to not use a FQDN
  44       for system name.
  45     + Add "-f json0" to provide a more regular/machine-parsable output
  46       to JSON output, even when not compiled with --enable-json0.
  47   * Fixes:
  48     + Handle team interfaces like a bond. Real MAC address cannot be
  49       retrieved yet.
  50
  51 lldpd (0.9.7)
  52   * Changes:
  53     + Attach remote TTL to port instead of chassis.
  54     + JSON support is now built-in and unconditionally enabled. Use
  55       --enable-json0 to keep the pre-0.9.2 json-c format.
  56     + When logging to syslog and daemonizing, don't log to stderr.
  57     + vxlan interfaces are now ignored as they are multi-point interfaces.
  58     + Maximum number of neighbors for an interface is increased from 4 to 32.
  59
  60 lldpd (0.9.6)
  61   * Changes:
  62     + Add a compile-time option to restore pre-0.9.2 JSON format (when
  63       using json-c). Use `--enable-json0` to enable this option.
  64     + Support for newer ethtool interface on Linux
  65       (ETHTOOL_GLINKSETTINGS) and additional speed settings.
  66     + Current MAU type is displayed even when autoneg is off.
  67     + Increase netlink receive buffer by default. Can be changed at
  68       compile-time through ./configure.
  69   * Fixes:
  70     + Correctly parse LLDP-MED civic address when the length of the
  71       TLV exceeds the length of the address.
  72     + Fix 100% CPU on some rare error condition.
  73     + Fix lost timer when an interface is enslaved on Linux.
  74
  75 lldpd (0.9.5)
  76   * Changes:
  77     + More Ethernet media supported. However, RFC4836 is quite
  78       out-of-date with respected to 10G+ speeds, bringing some
  79       inaccuracies.
  80     + Directly get media information for an interface without using
  81       the privileged process.
  82     + LLDP-MED capability TLV is not sent when LLDP-MED is not enabled,
  83       even if other LLDP-MED TLV are present.
  84   * Fixes:
  85     + Compilation fix with older versions of GCC.
  86     + Don't use ethtool at all to get real MAC address for enslaved
  87       devices (always use /proc).
  88
  89 lldpd (0.9.4)
  90   * Changes:
  91     + Make lldpd accepts a `-p` option to specify the PID file.
  92     + Ability to change multicast MAC address to two additional values
  93       to reach customer bridges.
  94     + lldpcli will now display chassis TTL when detailed view is enabled.
  95   * Fixes:
  96     + Fix setting of local value for port ID.
  97     + Fix compilation with BSD make.
  98     + Ensure lldpcli returns an error code on invalid commands.
  99
 100 lldpd (0.9.3)
 101   * Changes:
 102     + Do not rely on support of constructors for liblldpctl.
 103     + Always log to stderr (even in addition to syslog).
 104     + `lldpcli watch` accepts a limit on the number of received events.
 105   * Fixes:
 106     + `lldpcli -f {xml,json} watch` should work now.
 107     + Consider `veth` interfaces as physical interfaces.
 108
 109 lldpd (0.9.2)
 110   * Changes:
 111     + Ability to add/remove/replace custom TLV from lldpcli.
 112     + LLDP-MED capabilities are displayed differently in lldpcli.
 113     + Limit the maximum depth (5) when trying to apply a VLAN.
 114     + Change JSON output format when using json-c to match Jansson
 115       output.
 116     + Integration tests for the major parts of lldpd, including use of
 117       address and leak sanitizer.
 118   * Fixes:
 119     + LLDP-MED POE TLV are now displayed in lldpcli.
 120     + Ignore lower link when it is in another namespace.
 121     + Fix various problems with interfaces being enslaved.
 122     + Fix a memory leak when modifying port-related settings.
 123
 124 lldpd (0.9.1)
 125   * Changes:
 126     + Rework packaging for OS X to make it work with El Capitan. To
 127       simplify a bit, it is not possible anymore to build fat
 128       binaries. Latest version of OS X supporting 32bit was 10.6.
 129   * Fixes:
 130     + By default, when using port alias as description, use port name
 131       as port ID.
 132     + Miscellaneous fixes with netlink cache.
 133     + Ensure large netlink messages can be received.
 134
 135 lldpd (0.9.0)
 136   * Changes:
 137     + Don't rely on libnl3 for netlink. Reuse the previous code and
 138       implement a lighweight cache.
 139
 140 lldpd (0.8.0, never released)
 141   * Changes:
 142     + PIE is now disabled by default. It's too difficult to reliably
 143       detect if it works. Use --enable-pie to enable it.
 144     + Retrieve the permanent MAC address of an interface through
 145       ethtool for Linux if /proc/net/bonding is not available.
 146     + Running lldpd with "-d" will keep the process in foreground but
 147       logs will still go to syslog. To log to the console, add at
 148       least one "-d".
 149     + Fix minimal kernel version to 2.6.39. Add a runtime warning when
 150       this is not the case.
 151     + Remove old bridge code (the one using ioctl).
 152     + Don't discard down interfaces. Notably, this enables us to keep
 153       their specific configuration if any.
 154     + For Linux, switch to libnl3. Be aware of the licensing issues in
 155       case of static linking.
 156     + Introduce the notion of default local port. New interfaces will
 157       use it as a base. This allows setting various MED stuff.
 158     + Provide an apparmor profile (untested).
 159   * Fixes:
 160     + Fix a buffer overflow when receiving a too large management
 161       address TLV. Unless hardening has been disabled, this overflow
 162       cannot be used for arbitrary code execution.
 163     + Update LLDP-MED policy L2 priority values to match
 164       802.1Q-2005. This may be a breaking change.
 165
 166 lldpd (0.7.17)
 167   * Fixes:
 168     + Fix the way libevent configure is called.
 169     + Fix an infinite loop when using veth on Linux 4.1+ kernels.
 170     + Make CDP advertise the appropriate kernel name as platform,
 171       not just "Linux".
 172
 173 lldpd (0.7.16)
 174   * Changes:
 175     + For Linux, 2.6.32 is now the minimal required kernel. When using
 176       an older kernel, use `--enable-oldies`.
 177     + For Linux, use netlink to retrieve information about bridges,
 178       VLAN and bonds. The code was contributed by Cumulus Networks.
 179     + Use symbol versioning for liblldpctl.so.
 180     + Ability to get local chassis information with "show
 181       chassis".
 182     + The library also has the same ability with the
 183       `lldpctl_get_local_chassis()` function. It is also possible to
 184       get a chassis atom from a port with `lldpctl_k_port_chassis`
 185       key. This is now the preferred way to retrieve chassis related
 186       information.
 187   * Fixes:
 188     + Fix build on OS X.
 189     + Accept "language" when configuring MED location as a civic address.
 190
 191 lldpd (0.7.15)
 192   * Changes:
 193     + Optional features can be configured with "auto" to autodetect if
 194       they are usable. This is the default value for JSON and XML support.
 195     + Ability to send and decode custom/unknown TLV. Thanks to Alexandru
 196       Ardelean.
 197     + Modify checksum function. While this should be strictly
 198       equivalent, if you notice CDP packets not accepted anymore, this
 199       change is the first culprit.
 200
 201 lldpd (0.7.14)
 202   * Changes:
 203     + Shutdown LLPDU are sent on MSAP change and when lldpd exits.
 204     + When an exact IP is provided as a management pattern, use it
 205       unconditionally.
 206     + Ability to set port ID and description to an arbitrary value,
 207       thanks to Alexandru Ardelean.
 208   * Fixes:
 209     + Incorrect boundary check when decoding management address and
 210       protocol identity may lead to lldpd crash when processing
 211       malformed LLDPDU.
 212     + Many edge cases where lldpd was leaving hanging processes after
 213       crashing.
 214
 215 lldpd (0.7.13)
 216   * Fixes:
 217     + Unbreak customization of Unix socket path from command line.
 218
 219 lldpd (0.7.12)
 220   * Changes:
 221     + Interface pattern, management pattern, system description,
 222       system platform and system hostname can be unconfigured to their
 223       default values.
 224   * Fixes:
 225     + Don't complain when parsing a commented line.
 226     + Correctly persist configuration changes for "system interface
 227       promiscuous", "system interface description" "med fast-start
 228       enable", "pause" and "resume".
 229     + Fix listening on bond devices for old kernels (< 2.6.27).
 230
 231 lldpd (0.7.11)
 232   * Changes:
 233     + Ship bash and zsh completion.
 234     + Abort when some command-line options are repeated.
 235   * Fixes:
 236     + Handle correctly read failures in liblldpctl.
 237
 238 lldpd (0.7.10)
 239   * Changes:
 240     + Ability to set promiscuous mode to work around bugs of some
 241       switches encapsulating LLDP frames inside 802.1Q frames.
 242     + JSON support for lldpcli can use json-c instead of jansson,
 243       thanks to Michel Stam.
 244   * Fixes:
 245     + Fix checksum computation for Cisco CDP.
 246     + Fix ability to disable LLDP.
 247     + Fix seccomp sandbox, thanks to Patrick McLean.
 248
 249 lldpd (0.7.9)
 250   * Changes:
 251     + Default location for chroot, socket and PID are now configurable
 252       in `./configure`. The default location is based on the value of
 253       `runstatedir` which in turn may be based on the value of
 254       `localstatedir` which defaults to `/usr/local/var`. Therefore,
 255       to get the previous locations, lldpd should be configured with
 256       `./configure --localstatedir=/var`.
 257     + Add support for shutdown LLDPU.
 258     + Ability to configure IP management pattern from lldpcli.
 259     + Ability to choose what port ID should be (MAC or interface name).
 260   * Fixes:
 261     + Fix `configure system bond-slave-src-mac-type local`. Also use
 262       it as default.
 263
 264 lldpd (0.7.8)
 265   * Changes:
 266     + Android support
 267     + Add the possibility to disable privilege separation (lower
 268       memory consumption, lower security, don't do it).
 269     + Interfaces can now be whitelisted. For example, *,!eth*,!!eth1
 270       is a valid pattern for all interfaces except eth ones, except
 271       eth1. Moreover, on exact match, an matching interface
 272       circumvents most sanity checks (like VLAN handling).
 273     + Ability to override the hostname.
 274   * Fixes:
 275     + Don't hard-code default values for system name, system
 276       description and port description. When the field is not present,
 277       just don't display it.
 278     + Fix lldpcli behaviour when suid.
 279     + On OSX, don't use p2p0 interfaces: it would break WLAN.
 280     + Fix SNMP support on RHEL.
 281
 282 lldpd (0.7.7)
 283   * Changes:
 284     + Use a locally administered MAC address or an arbitrary one
 285       instead of null MAC address for bond devices on Linux. This is
 286       configurable through `lldpcli`.
 287     + Add support for "team" driver (alternative to bond devices).
 288     + Preliminary support for DTrace/systemtap.
 289     + Preliminary support for seccomp (for monitor process).
 290     + Setup chroot inside lldpd instead of relying on init script.
 291   * Fixes:
 292     + Various bugs related to fixed point number handling (for
 293       coordinates in LLDP-MED)
 294     + Fix a regression in how MAC address of an enslaved device is
 295       retrieved.
 296
 297 lldpd (0.7.6)
 298   * Changes:
 299     + Provide a way to build packages for OSX.
 300     + Add an option to update interface description with neighbor name.
 301   * Fixes:
 302     + Compilation fix for OSX 10.6.
 303
 304 lldpd (0.7.5)
 305   * Fixes:
 306     + Segfault while tokenizing in lldpcli.
 307
 308 lldpd (0.7.4)
 309   * Fixes:
 310     + Segfault in lldpcli.
 311     + Memory leak in liblldpctl when using a custom log handler.
 312     + Fix some unaligned memory accesses.
 313     + Fix frame reception on OpenBSD.
 314   * Changes:
 315     + Allow to configure hold value from lldpcli (and hence the TTL).
 316     + Allow to configure pattern for valid interfaces from lldpcli.
 317     + Allow to override system description from lldpcli.
 318     + Display the neighbor connected as the process title (or the
 319       number of connected neighbors).
 320
 321 lldpd (0.7.3)
 322   * Changes:
 323     + DragonFly BSD support.
 324     + Solaris support (incomplete).
 325     + LLDP-MED fast start support (thanks to Roopa Prabhu).
 326     + Provide global statistics through "show statistics summary"
 327       command (thanks to Roopa Prabhu).
 328   * Fixes:
 329     + Fix IPv4/IPv6 address discovery in Linux.
 330
 331 lldpd (0.7.2)
 332   * Changes:
 333     + lldpd can be configured through /etc/lldpd.conf and
 334       /etc/lldpd.d. All commands accepted by lldpcli are accepted.
 335     + Lock BPF interfaces before handing them to chrooted process on
 336       BSD.
 337     + Limit the number of neighbors for each port to 4 (per protocol).
 338     + Force CDPv2 protocol with argument `-ccc`.
 339     + Provide port statistics through "show statistics" command
 340       (thanks to Roopa Prabhu).
 341   * Fixes:
 342     + Driver whitelisting is done before checking if an interface has
 343       a lower interface in Linux.
 344     + Expire remote ports and chassis in a timely manner.
 345
 346 lldpd (0.7.1)
 347   * Changes:
 348     + Mac OS X support, sponsored by Xcloud, Mac cloud server hosting
 349       provider. http://xcloud.me/
 350     + Upstart and systemd support.
 351     + Remove Unix socket when there is no process listening.
 352
 353 lldpd (0.7.0)
 354   * Changes:
 355     + FreeBSD support.
 356     + OpenBSD support.
 357     + NetBSD support.
 358     + Detect interface changes.
 359     + CLI for lldpctl: lldpcli.
 360     + Allow to disable LLDP protocol (with `-ll`). In this case, the
 361       first enabled protocol will be used when no neighbor is detected.
 362     + Allow to filter debug logs using tokens. Add more debug logs.
 363     + lldpctl can now output JSON.
 364     + Use netlink to gather interface information on Linux.
 365     + Don't use ioctl for bridges anymore on Linux. The configure
 366       option `--enable-oldies` allow to reenable their uses for
 367       systems not supporting sysfs.
 368
 369 lldpd (0.6.1)
 370   * Changes:
 371     + Provide liblldpctl.so, a library to interface with lldpd. The
 372       documentation is provided through Doxygen. See src/lib/lldpctl.h
 373       which contains all the exported functions.
 374     + Make lldpctl uses liblldpctl.so.
 375     + Add a "watch" option to lldpctl to monitor neighbor changes.
 376     + Add the possibility to display the current configuration of
 377       lldpd with lldpctl. Also add the possibility to reset the
 378       current transmit delay.
 379
 380 lldpd (0.6)
 381   * Changes:
 382     + Allow lldpctl to display hidden ports.
 383     + Add a switch to specify interfaces to use to get chassis ID.
 384     + Support for multiple management addresses and IPv6 management
 385       addresses. Contributed by João Valverde.
 386     + Switch to libevent. See README.md for details.
 387     + Partial rewrite of the SNMP part. Less code.
 388     + Unit tests for SNMP.
 389     + Major rewrite of the protocol between lldpd and lldpctl. Less
 390       code.
 391   * Fixes:
 392     + Several small SNMP fixes (discovered by unit tests).
 393
 394 lldpd (0.5.7)
 395  * Fixes:
 396     + Configure issue with NetSNMP and some linkers
 397     + Fix infinite loop for the receive part: on certain conditions,
 398       lldpd will stop sending packets and stop updating local data.
 399
 400 lldpd (0.5.6)
 401   * Changes:
 402     + Send and receive native VLAN TLV with CDP
 403     + Add a whitelist for some drivers (currently: dsa and veth)
 404   * Fixes:
 405     + Compilation issues with NetSNMP 5.7 (and with earlier versions too)
 406     + Small optimization of BPF filter
 407
 408 lldpd (0.5.5)
 409   * Changes:
 410     + Support for PPVID and PI Dot1 TLV, thanks to Shuah Khan.
 411     + Extend whitelist with possibility to blacklist.
 412   * Fixes:
 413     + Key/value output was incorrect when a dot was present in
 414       interface names. This is fixed but it is preferable to use XML
 415       output since the parsing is more difficult in this case.
 416     + Only grab DMI information once. Only uses DMI for x86 platform.
 417     + Padding issues with socket protocol. This introduces a change in
 418       the socket protocol!
 419     + Fix a segfault when neither /etc/os-release nor lsb_release
 420       are available.
 421
 422 lldpd (0.5.4)
 423   * Changes:
 424     + Get OS information from /etc/os-release if available. Patch from
 425       Michael Tremer.
 426     + Add a flag to specify which interfaces lldpd should listen to.
 427
 428 lldpd (0.5.3)
 429   * Changes:
 430     + Handle Dot3 POE-MDI TLV (802.3af and 802.3at).
 431     + Allow to set Dot3 POE-MDI from lldpctl.
 432   * Fixes:
 433     + Allow root to change configuration of lldpd when lldpctl has suid set.
 434
 435 lldpd (0.5.2)
 436   * Changes:
 437     + More flexible smart mode and new default. Manual page has been updated.
 438     + Add a "receive-only" mode with "-r" switch.
 439
 440 lldpd (0.5.1)
 441   * Changes:
 442     + Allow to force a protocol even when no peer for this protocol is
 443       detected.
 444     + Add a smart mode that allows to discard bogus port information,
 445       for example CDP packets that are flooded through a switch that
 446       does not support CDP.
 447     + Allow to set LLDP-MED network policy from lldpctl, thanks to a patch from
 448       Philipp Kempgen.
 449     + Allow to set LLDP-MED POE-MDI from lldpctl.
 450     + Add a summary of available options in "lldpd -h" and "lldpctl -h",
 451       thanks to a patch from Jorge Boncompte.
 452     + Add a new output (keyvalue) for lldpctl.
 453     + Listen on VLAN using an appropriate BPF filter, VLAN
 454       decapsulation. Older "listen on vlan" feature is discarded. See
 455       README for more information on the new feature.
 456     + Use output of lsb_release if available for system description.
 457   * Fixes:
 458     + Ignore interface with no queue. It should filter out interfaces
 459       like "vnet0" that would fail if we try to send something on them.
 460     + Don't check CDP checksums (not really a fix but it appears that
 461       Cisco checksum have some difficult corner cases).
 462
 463 lldpd (0.5.0)
 464   * Changes:
 465     + lldpd can now handle several systems on the same port. This
 466       modification also allows to speak to a switch using CDP and LLDP
 467       for example.
 468     + The way that lldpd gathers information for each port has been
 469       abstracted. This should allow to support more systems (BSD for
 470       examples) or switch cores in the future. Sending/receive support
 471       is also abstracted.
 472     + Add "-k" switch to avoid to emit too much information on running
 473       kernel.
 474     + Support of ifAlias with kernel >= 2.6.28
 475     + Lot of portability stuff. lldpd can now be compiled on RHEL
 476       2.1. Still Linux-only though.
 477     + Add an option to specify AgentX socket (-X).
 478     + Add some unit tests
 479     + lldpctl has been reworked; it is now able to output data in XML
 480       format for easier parsing. Patches were provided by Andreas
 481       Hofmeister.
 482   * Fixes:
 483     + Fix EDP VLAN handling
 484     + Silent warnings about bridge stuff.
 485     + Copy /etc/localtime into chroot before starting lldpd daemon to
 486       ensure correct timestamps for logs.
 487
 488 lldpd (0.4.1)
 489   * Fix EDP handling when there is no VLAN
 490   * Fix CDP version to not always be 1
 491   * Misc fix:
 492      + incorrect number of arguments for a LLOG_INFO call
 493      + fix SNMP last change in case this change occurs before start time
 494
 495 lldpd (0.4)
 496   * Rewrite of packet builder and parser to be able to cope with
 497     architecture that cannot do unaligned read. For decoder, we don't
 498     cast structures any more since they can be unaligned. For encoder,
 499     we use memcpy through the use of macro that build packets step by
 500     step.
 501
 502 lldpd (0.3.2)
 503   * Fix LLDP-MED support
 504
 505 lldpd (0.3.1)
 506   * Misc fixes, including memory leaks
 507
 508 lldpd (0.3)
 509   * Initial support of LLDP-MED
 510   * Fix for bridge detection (don't send bridge ioctl on random interfaces)
 511   * For bonded devices, get the real hardware address. For inactive
 512     slaves, transmit using a random MAC address.
 513
 514 lldpd (0.2.1)
 515   * Fix a syntax error in manual page
 516   * Fix open() calls
 517
 518 lldpd (0.2)
 519   * Add privilege separation
 520   * Add FDP support
 521   * Support CDP encapsulated into native VLAN
 522   * Various fixes
 523
 524 lldpd (0.1)
 525   * Initial release
