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