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