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   4       out-of-date with respected to 10G+ speeds, bringing some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