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  15       out-of-date with respected to 10G+ speeds, bringing some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

 444   * Rewrite of packet builder and parser to be able to cope with
 445     architecture that cannot do unaligned read. For decoder, we don't
 446     cast structures any more since they can be unaligned. For encoder,
 447     we use memcpy through the use of macro that build packets step by
 448     step.
