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