   1 lldpd (1.0.4)
   2   * Changes:
   3     + Add "configure system max-neighbors XX" command to modify maximum
   4       of neighbors accepted per port.
   5     + Implement lldpRemOrgDefInfoTable table for custom TLVs.
   6   * Fix:
   7     + Better compliance for statsTLVsUnrecognizedTotal and
   8       statsAgeoutsTotal counters.
   9     + On Linux, handle rare blocking case in Netlink code.
  10
  11 lldpd (1.0.3)
  12   * Fix:
  13     + Fix creation of chroot directory.
  14
  15 lldpd (1.0.2)
  16   * Changes:
  17     + On Linux, the monitor process will now drop its privileges
  18       instead of running as root. It will keep CAP_NET_RAW,
  19       CAP_NET_ADMIN and CAP_DAC_OVERRIDE capabilities.
  20     + Support for CDP PD PoE (with negotiation). Thanks to Gustav
  21       Wiklander.
  22     + Move support for bonded devices on Linux < 2.6.27 into the
  23       `--enable-oldies` option. This avoids duplicate packets
  24       starting from Linux 4.19.
  25
  26 lldpd (1.0.1)
  27   * Fix:
  28     + Use "mkdir -p" instead of "mkdir" in systemd unit.
  29
  30 lldpd (1.0.0)
  31   * Changes:
  32     + Chassis ID can be set to an arbitrary value with "configure system
  33       chassisid".
  34     + Port description can be overriden directly with "configure lldp
  35       portdescription".
  36     + Command "configure system interface permanent" enables one to
  37       specify a pattern for interfaces to be kept in memory even when
  38       they are removed from the system.
  39   * Fix:
  40     + Ensure chassis-related changes are propagated immediately.
  41     + Ensure management address change is correctly detected.
  42
  43 lldpd (0.9.9)
  44   * Changes:
  45     + lldpcli can now display local interfaces with LLDP data sent on
  46       each of them ("show interfaces").
  47     + As Dot3 PD device, echo back allocated value from PSE device.
  48   * Fix:
  49     + Don't remove interfaces when they are released from a bridge.
  50     + Don't use "expect stop" with Upstart. It's buggy.
  51
  52 lldpd (0.9.8)
  53   * Changes:
  54     + "Station" capability is only set if no other bit is set.
  55     + Use ethtool to get permanent address for bonds and teams. This
  56       might provide different results than the previous method. Some
  57       devices may still use the previous method.
  58     + Don't run ethtool as root. Kernels older than 2.6.19 won't get
  59       link information anymore.
  60     + Add "configure system hostname ." option to not use a FQDN
  61       for system name.
  62     + Add "-f json0" to provide a more regular/machine-parsable output
  63       to JSON output, even when not compiled with --enable-json0.
  64   * Fixes:
  65     + Handle team interfaces like a bond. Real MAC address cannot be
  66       retrieved yet.
  67
  68 lldpd (0.9.7)
  69   * Changes:
  70     + Attach remote TTL to port instead of chassis.
  71     + JSON support is now built-in and unconditionally enabled. Use
  72       --enable-json0 to keep the pre-0.9.2 json-c format.
  73     + When logging to syslog and daemonizing, don't log to stderr.
  74     + vxlan interfaces are now ignored as they are multi-point interfaces.
  75     + Maximum number of neighbors for an interface is increased from 4 to 32.
  76
  77 lldpd (0.9.6)
  78   * Changes:
  79     + Add a compile-time option to restore pre-0.9.2 JSON format (when
  80       using json-c). Use `--enable-json0` to enable this option.
  81     + Support for newer ethtool interface on Linux
  82       (ETHTOOL_GLINKSETTINGS) and additional speed settings.
  83     + Current MAU type is displayed even when autoneg is off.
  84     + Increase netlink receive buffer by default. Can be changed at
  85       compile-time through ./configure.
  86   * Fixes:
  87     + Correctly parse LLDP-MED civic address when the length of the
  88       TLV exceeds the length of the address.
  89     + Fix 100% CPU on some rare error condition.
  90     + Fix lost timer when an interface is enslaved on Linux.
  91
  92 lldpd (0.9.5)
  93   * Changes:
  94     + More Ethernet media supported. However, RFC4836 is quite
  95       out-of-date with respected to 10G+ speeds, bringing some
  96       inaccuracies.
  97     + Directly get media information for an interface without using
  98       the privileged process.
  99     + LLDP-MED capability TLV is not sent when LLDP-MED is not enabled,
 100       even if other LLDP-MED TLV are present.
 101   * Fixes:
 102     + Compilation fix with older versions of GCC.
 103     + Don't use ethtool at all to get real MAC address for enslaved
 104       devices (always use /proc).
 105
 106 lldpd (0.9.4)
 107   * Changes:
 108     + Make lldpd accepts a `-p` option to specify the PID file.
 109     + Ability to change multicast MAC address to two additional values
 110       to reach customer bridges.
 111     + lldpcli will now display chassis TTL when detailed view is enabled.
 112   * Fixes:
 113     + Fix setting of local value for port ID.
 114     + Fix compilation with BSD make.
 115     + Ensure lldpcli returns an error code on invalid commands.
 116
 117 lldpd (0.9.3)
 118   * Changes:
 119     + Do not rely on support of constructors for liblldpctl.
 120     + Always log to stderr (even in addition to syslog).
 121     + `lldpcli watch` accepts a limit on the number of received events.
 122   * Fixes:
 123     + `lldpcli -f {xml,json} watch` should work now.
 124     + Consider `veth` interfaces as physical interfaces.
 125
 126 lldpd (0.9.2)
 127   * Changes:
 128     + Ability to add/remove/replace custom TLV from lldpcli.
 129     + LLDP-MED capabilities are displayed differently in lldpcli.
 130     + Limit the maximum depth (5) when trying to apply a VLAN.
 131     + Change JSON output format when using json-c to match Jansson
 132       output.
 133     + Integration tests for the major parts of lldpd, including use of
 134       address and leak sanitizer.
 135   * Fixes:
 136     + LLDP-MED POE TLV are now displayed in lldpcli.
 137     + Ignore lower link when it is in another namespace.
 138     + Fix various problems with interfaces being enslaved.
 139     + Fix a memory leak when modifying port-related settings.
 140
 141 lldpd (0.9.1)
 142   * Changes:
 143     + Rework packaging for OS X to make it work with El Capitan. To
 144       simplify a bit, it is not possible anymore to build fat
 145       binaries. Latest version of OS X supporting 32bit was 10.6.
 146   * Fixes:
 147     + By default, when using port alias as description, use port name
 148       as port ID.
 149     + Miscellaneous fixes with netlink cache.
 150     + Ensure large netlink messages can be received.
 151
 152 lldpd (0.9.0)
 153   * Changes:
 154     + Don't rely on libnl3 for netlink. Reuse the previous code and
 155       implement a lighweight cache.
 156
 157 lldpd (0.8.0, never released)
 158   * Changes:
 159     + PIE is now disabled by default. It's too difficult to reliably
 160       detect if it works. Use --enable-pie to enable it.
 161     + Retrieve the permanent MAC address of an interface through
 162       ethtool for Linux if /proc/net/bonding is not available.
 163     + Running lldpd with "-d" will keep the process in foreground but
 164       logs will still go to syslog. To log to the console, add at
 165       least one "-d".
 166     + Fix minimal kernel version to 2.6.39. Add a runtime warning when
 167       this is not the case.
 168     + Remove old bridge code (the one using ioctl).
 169     + Don't discard down interfaces. Notably, this enables us to keep
 170       their specific configuration if any.
 171     + For Linux, switch to libnl3. Be aware of the licensing issues in
 172       case of static linking.
 173     + Introduce the notion of default local port. New interfaces will
 174       use it as a base. This allows setting various MED stuff.
 175     + Provide an apparmor profile (untested).
 176   * Fixes:
 177     + Fix a buffer overflow when receiving a too large management
 178       address TLV. Unless hardening has been disabled, this overflow
 179       cannot be used for arbitrary code execution.
 180     + Update LLDP-MED policy L2 priority values to match
 181       802.1Q-2005. This may be a breaking change.
 182
 183 lldpd (0.7.17)
 184   * Fixes:
 185     + Fix the way libevent configure is called.
 186     + Fix an infinite loop when using veth on Linux 4.1+ kernels.
 187     + Make CDP advertise the appropriate kernel name as platform,
 188       not just "Linux".
 189
 190 lldpd (0.7.16)
 191   * Changes:
 192     + For Linux, 2.6.32 is now the minimal required kernel. When using
 193       an older kernel, use `--enable-oldies`.
 194     + For Linux, use netlink to retrieve information about bridges,
 195       VLAN and bonds. The code was contributed by Cumulus Networks.
 196     + Use symbol versioning for liblldpctl.so.
 197     + Ability to get local chassis information with "show
 198       chassis".
 199     + The library also has the same ability with the
 200       `lldpctl_get_local_chassis()` function. It is also possible to
 201       get a chassis atom from a port with `lldpctl_k_port_chassis`
 202       key. This is now the preferred way to retrieve chassis related
 203       information.
 204   * Fixes:
 205     + Fix build on OS X.
 206     + Accept "language" when configuring MED location as a civic address.
 207
 208 lldpd (0.7.15)
 209   * Changes:
 210     + Optional features can be configured with "auto" to autodetect if
 211       they are usable. This is the default value for JSON and XML support.
 212     + Ability to send and decode custom/unknown TLV. Thanks to Alexandru
 213       Ardelean.
 214     + Modify checksum function. While this should be strictly
 215       equivalent, if you notice CDP packets not accepted anymore, this
 216       change is the first culprit.
 217
 218 lldpd (0.7.14)
 219   * Changes:
 220     + Shutdown LLPDU are sent on MSAP change and when lldpd exits.
 221     + When an exact IP is provided as a management pattern, use it
 222       unconditionally.
 223     + Ability to set port ID and description to an arbitrary value,
 224       thanks to Alexandru Ardelean.
 225   * Fixes:
 226     + Incorrect boundary check when decoding management address and
 227       protocol identity may lead to lldpd crash when processing
 228       malformed LLDPDU.
 229     + Many edge cases where lldpd was leaving hanging processes after
 230       crashing.
 231
 232 lldpd (0.7.13)
 233   * Fixes:
 234     + Unbreak customization of Unix socket path from command line.
 235
 236 lldpd (0.7.12)
 237   * Changes:
 238     + Interface pattern, management pattern, system description,
 239       system platform and system hostname can be unconfigured to their
 240       default values.
 241   * Fixes:
 242     + Don't complain when parsing a commented line.
 243     + Correctly persist configuration changes for "system interface
 244       promiscuous", "system interface description" "med fast-start
 245       enable", "pause" and "resume".
 246     + Fix listening on bond devices for old kernels (< 2.6.27).
 247
 248 lldpd (0.7.11)
 249   * Changes:
 250     + Ship bash and zsh completion.
 251     + Abort when some command-line options are repeated.
 252   * Fixes:
 253     + Handle correctly read failures in liblldpctl.
 254
 255 lldpd (0.7.10)
 256   * Changes:
 257     + Ability to set promiscuous mode to work around bugs of some
 258       switches encapsulating LLDP frames inside 802.1Q frames.
 259     + JSON support for lldpcli can use json-c instead of jansson,
 260       thanks to Michel Stam.
 261   * Fixes:
 262     + Fix checksum computation for Cisco CDP.
 263     + Fix ability to disable LLDP.
 264     + Fix seccomp sandbox, thanks to Patrick McLean.
 265
 266 lldpd (0.7.9)
 267   * Changes:
 268     + Default location for chroot, socket and PID are now configurable
 269       in `./configure`. The default location is based on the value of
 270       `runstatedir` which in turn may be based on the value of
 271       `localstatedir` which defaults to `/usr/local/var`. Therefore,
 272       to get the previous locations, lldpd should be configured with
 273       `./configure --localstatedir=/var`.
 274     + Add support for shutdown LLDPU.
 275     + Ability to configure IP management pattern from lldpcli.
 276     + Ability to choose what port ID should be (MAC or interface name).
 277   * Fixes:
 278     + Fix `configure system bond-slave-src-mac-type local`. Also use
 279       it as default.
 280
 281 lldpd (0.7.8)
 282   * Changes:
 283     + Android support
 284     + Add the possibility to disable privilege separation (lower
 285       memory consumption, lower security, don't do it).
 286     + Interfaces can now be whitelisted. For example, *,!eth*,!!eth1
 287       is a valid pattern for all interfaces except eth ones, except
 288       eth1. Moreover, on exact match, an matching interface
 289       circumvents most sanity checks (like VLAN handling).
 290     + Ability to override the hostname.
 291   * Fixes:
 292     + Don't hard-code default values for system name, system
 293       description and port description. When the field is not present,
 294       just don't display it.
 295     + Fix lldpcli behaviour when suid.
 296     + On OSX, don't use p2p0 interfaces: it would break WLAN.
 297     + Fix SNMP support on RHEL.
 298
 299 lldpd (0.7.7)
 300   * Changes:
 301     + Use a locally administered MAC address or an arbitrary one
 302       instead of null MAC address for bond devices on Linux. This is
 303       configurable through `lldpcli`.
 304     + Add support for "team" driver (alternative to bond devices).
 305     + Preliminary support for DTrace/systemtap.
 306     + Preliminary support for seccomp (for monitor process).
 307     + Setup chroot inside lldpd instead of relying on init script.
 308   * Fixes:
 309     + Various bugs related to fixed point number handling (for
 310       coordinates in LLDP-MED)
 311     + Fix a regression in how MAC address of an enslaved device is
 312       retrieved.
 313
 314 lldpd (0.7.6)
 315   * Changes:
 316     + Provide a way to build packages for OSX.
 317     + Add an option to update interface description with neighbor name.
 318   * Fixes:
 319     + Compilation fix for OSX 10.6.
 320
 321 lldpd (0.7.5)
 322   * Fixes:
 323     + Segfault while tokenizing in lldpcli.
 324
 325 lldpd (0.7.4)
 326   * Fixes:
 327     + Segfault in lldpcli.
 328     + Memory leak in liblldpctl when using a custom log handler.
 329     + Fix some unaligned memory accesses.
 330     + Fix frame reception on OpenBSD.
 331   * Changes:
 332     + Allow to configure hold value from lldpcli (and hence the TTL).
 333     + Allow to configure pattern for valid interfaces from lldpcli.
 334     + Allow to override system description from lldpcli.
 335     + Display the neighbor connected as the process title (or the
 336       number of connected neighbors).
 337
 338 lldpd (0.7.3)
 339   * Changes:
 340     + DragonFly BSD support.
 341     + Solaris support (incomplete).
 342     + LLDP-MED fast start support (thanks to Roopa Prabhu).
 343     + Provide global statistics through "show statistics summary"
 344       command (thanks to Roopa Prabhu).
 345   * Fixes:
 346     + Fix IPv4/IPv6 address discovery in Linux.
 347
 348 lldpd (0.7.2)
 349   * Changes:
 350     + lldpd can be configured through /etc/lldpd.conf and
 351       /etc/lldpd.d. All commands accepted by lldpcli are accepted.
 352     + Lock BPF interfaces before handing them to chrooted process on
 353       BSD.
 354     + Limit the number of neighbors for each port to 4 (per protocol).
 355     + Force CDPv2 protocol with argument `-ccc`.
 356     + Provide port statistics through "show statistics" command
 357       (thanks to Roopa Prabhu).
 358   * Fixes:
 359     + Driver whitelisting is done before checking if an interface has
 360       a lower interface in Linux.
 361     + Expire remote ports and chassis in a timely manner.
 362
 363 lldpd (0.7.1)
 364   * Changes:
 365     + Mac OS X support, sponsored by Xcloud, Mac cloud server hosting
 366       provider. http://xcloud.me/
 367     + Upstart and systemd support.
 368     + Remove Unix socket when there is no process listening.
 369
 370 lldpd (0.7.0)
 371   * Changes:
 372     + FreeBSD support.
 373     + OpenBSD support.
 374     + NetBSD support.
 375     + Detect interface changes.
 376     + CLI for lldpctl: lldpcli.
 377     + Allow to disable LLDP protocol (with `-ll`). In this case, the
 378       first enabled protocol will be used when no neighbor is detected.
 379     + Allow to filter debug logs using tokens. Add more debug logs.
 380     + lldpctl can now output JSON.
 381     + Use netlink to gather interface information on Linux.
 382     + Don't use ioctl for bridges anymore on Linux. The configure
 383       option `--enable-oldies` allow to reenable their uses for
 384       systems not supporting sysfs.
 385
 386 lldpd (0.6.1)
 387   * Changes:
 388     + Provide liblldpctl.so, a library to interface with lldpd. The
 389       documentation is provided through Doxygen. See src/lib/lldpctl.h
 390       which contains all the exported functions.
 391     + Make lldpctl uses liblldpctl.so.
 392     + Add a "watch" option to lldpctl to monitor neighbor changes.
 393     + Add the possibility to display the current configuration of
 394       lldpd with lldpctl. Also add the possibility to reset the
 395       current transmit delay.
 396
 397 lldpd (0.6)
 398   * Changes:
 399     + Allow lldpctl to display hidden ports.
 400     + Add a switch to specify interfaces to use to get chassis ID.
 401     + Support for multiple management addresses and IPv6 management
 402       addresses. Contributed by João Valverde.
 403     + Switch to libevent. See README.md for details.
 404     + Partial rewrite of the SNMP part. Less code.
 405     + Unit tests for SNMP.
 406     + Major rewrite of the protocol between lldpd and lldpctl. Less
 407       code.
 408   * Fixes:
 409     + Several small SNMP fixes (discovered by unit tests).
 410
 411 lldpd (0.5.7)
 412  * Fixes:
 413     + Configure issue with NetSNMP and some linkers
 414     + Fix infinite loop for the receive part: on certain conditions,
 415       lldpd will stop sending packets and stop updating local data.
 416
 417 lldpd (0.5.6)
 418   * Changes:
 419     + Send and receive native VLAN TLV with CDP
 420     + Add a whitelist for some drivers (currently: dsa and veth)
 421   * Fixes:
 422     + Compilation issues with NetSNMP 5.7 (and with earlier versions too)
 423     + Small optimization of BPF filter
 424
 425 lldpd (0.5.5)
 426   * Changes:
 427     + Support for PPVID and PI Dot1 TLV, thanks to Shuah Khan.
 428     + Extend whitelist with possibility to blacklist.
 429   * Fixes:
 430     + Key/value output was incorrect when a dot was present in
 431       interface names. This is fixed but it is preferable to use XML
 432       output since the parsing is more difficult in this case.
 433     + Only grab DMI information once. Only uses DMI for x86 platform.
 434     + Padding issues with socket protocol. This introduces a change in
 435       the socket protocol!
 436     + Fix a segfault when neither /etc/os-release nor lsb_release
 437       are available.
 438
 439 lldpd (0.5.4)
 440   * Changes:
 441     + Get OS information from /etc/os-release if available. Patch from
 442       Michael Tremer.
 443     + Add a flag to specify which interfaces lldpd should listen to.
 444
 445 lldpd (0.5.3)
 446   * Changes:
 447     + Handle Dot3 POE-MDI TLV (802.3af and 802.3at).
 448     + Allow to set Dot3 POE-MDI from lldpctl.
 449   * Fixes:
 450     + Allow root to change configuration of lldpd when lldpctl has suid set.
 451
 452 lldpd (0.5.2)
 453   * Changes:
 454     + More flexible smart mode and new default. Manual page has been updated.
 455     + Add a "receive-only" mode with "-r" switch.
 456
 457 lldpd (0.5.1)
 458   * Changes:
 459     + Allow to force a protocol even when no peer for this protocol is
 460       detected.
 461     + Add a smart mode that allows to discard bogus port information,
 462       for example CDP packets that are flooded through a switch that
 463       does not support CDP.
 464     + Allow to set LLDP-MED network policy from lldpctl, thanks to a patch from
 465       Philipp Kempgen.
 466     + Allow to set LLDP-MED POE-MDI from lldpctl.
 467     + Add a summary of available options in "lldpd -h" and "lldpctl -h",
 468       thanks to a patch from Jorge Boncompte.
 469     + Add a new output (keyvalue) for lldpctl.
 470     + Listen on VLAN using an appropriate BPF filter, VLAN
 471       decapsulation. Older "listen on vlan" feature is discarded. See
 472       README for more information on the new feature.
 473     + Use output of lsb_release if available for system description.
 474   * Fixes:
 475     + Ignore interface with no queue. It should filter out interfaces
 476       like "vnet0" that would fail if we try to send something on them.
 477     + Don't check CDP checksums (not really a fix but it appears that
 478       Cisco checksum have some difficult corner cases).
 479
 480 lldpd (0.5.0)
 481   * Changes:
 482     + lldpd can now handle several systems on the same port. This
 483       modification also allows to speak to a switch using CDP and LLDP
 484       for example.
 485     + The way that lldpd gathers information for each port has been
 486       abstracted. This should allow to support more systems (BSD for
 487       examples) or switch cores in the future. Sending/receive support
 488       is also abstracted.
 489     + Add "-k" switch to avoid to emit too much information on running
 490       kernel.
 491     + Support of ifAlias with kernel >= 2.6.28
 492     + Lot of portability stuff. lldpd can now be compiled on RHEL
 493       2.1. Still Linux-only though.
 494     + Add an option to specify AgentX socket (-X).
 495     + Add some unit tests
 496     + lldpctl has been reworked; it is now able to output data in XML
 497       format for easier parsing. Patches were provided by Andreas
 498       Hofmeister.
 499   * Fixes:
 500     + Fix EDP VLAN handling
 501     + Silent warnings about bridge stuff.
 502     + Copy /etc/localtime into chroot before starting lldpd daemon to
 503       ensure correct timestamps for logs.
 504
 505 lldpd (0.4.1)
 506   * Fix EDP handling when there is no VLAN
 507   * Fix CDP version to not always be 1
 508   * Misc fix:
 509      + incorrect number of arguments for a LLOG_INFO call
 510      + fix SNMP last change in case this change occurs before start time
 511
 512 lldpd (0.4)
 513   * Rewrite of packet builder and parser to be able to cope with
 514     architecture that cannot do unaligned read. For decoder, we don't
 515     cast structures any more since they can be unaligned. For encoder,
 516     we use memcpy through the use of macro that build packets step by
 517     step.
 518
 519 lldpd (0.3.2)
 520   * Fix LLDP-MED support
 521
 522 lldpd (0.3.1)
 523   * Misc fixes, including memory leaks
 524
 525 lldpd (0.3)
 526   * Initial support of LLDP-MED
 527   * Fix for bridge detection (don't send bridge ioctl on random interfaces)
 528   * For bonded devices, get the real hardware address. For inactive
 529     slaves, transmit using a random MAC address.
 530
 531 lldpd (0.2.1)
 532   * Fix a syntax error in manual page
 533   * Fix open() calls
 534
 535 lldpd (0.2)
 536   * Add privilege separation
 537   * Add FDP support
 538   * Support CDP encapsulated into native VLAN
 539   * Various fixes
 540
 541 lldpd (0.1)
 542   * Initial release
