lldpd: fix use of NULL in execl*

[thirdparty/lldpd.git] / NEWS

lldpd (0.7.10)
  * Features:
    + Ability to set promiscuous mode to work around bugs of some
      switches encapsulating LLDP frames inside 802.1Q frames.
  * Fix:
    + Fix checksum computation for Cisco CDP.
    + Fix ability to disable LLDP.

lldpd (0.7.9)
  * Changes:
    + Default location for chroot, socket and PID are now configurable
      in `./configure`. The default location is based on the value of
      `runstatedir` which in turn may be based on the value of
      `localstatedir` which defaults to `/usr/local/var`. Therefore,
      to get the previous locations, lldpd should be configured with
      `./configure --localstatedir=/var`.
  * Fixes:
    + Fix `configure system bond-slave-src-mac-type local`. Also use
      it as default.
  * Features:
    + Add support for shutdown LLDPU.
    + Ability to configure IP management pattern from lldpcli.
    + Ability to choose what port ID should be (MAC or interface name).

lldpd (0.7.8)
  * Fixes:
    + Don't hard-code default values for system name, system
      description and port description. When the field is not present,
      just don't display it.
    + Fix lldpcli behaviour when suid.
    + On OSX, don't use p2p0 interfaces: it would break WLAN.
    + Fix SNMP support on RHEL.
  * Features:
    + Android support
    + Add the possibility to disable privilege separation (lower
      memory consumption, lower security, don't do it).
    + Interfaces can now be whitelisted. For example, *,!eth*,!!eth1
      is a valid pattern for all interfaces except eth ones, except
      eth1. Moreover, on exact match, an matching interface
      circumvents most sanity checks (like VLAN handling).
    + Ability to override the hostname.

lldpd (0.7.7)
  * Features:
    + Use a locally administered MAC address or an arbitrary one
      instead of null MAC address for bond devices on Linux. This is
      configurable through `lldpcli`.
    + Add support for "team" driver (alternative to bond devices).
    + Preliminary support for DTrace/systemtap.
    + Preliminary support for seccomp (for monitor process).
    + Setup chroot inside lldpd instead of relying on init script.
  * Fixes:
    + Various bugs related to fixed point number handling (for
      coordinates in LLDP-MED)
    + Fix a regression in how MAC address of an enslaved device is
      retrieved.

lldpd (0.7.6)
  * Features:
    + Provide a way to build packages for OSX.
    + Add an option to update interface description with neighbor name.
  * Fixes:
    + Compilation fix for OSX 10.6.

lldpd (0.7.5)
  * Fixes:
    + Segfault while tokenizing in lldpcli.

lldpd (0.7.4)
  * Fixes:
    + Segfault in lldpcli.
    + Memory leak in liblldpctl when using a custom log handler.
    + Fix some unaligned memory accesses.
    + Fix frame reception on OpenBSD.
  * Features:
    + Allow to configure hold value from lldpcli (and hence the TTL).
    + Allow to configure pattern for valid interfaces from lldpcli.
    + Allow to override system description from lldpcli.
    + Display the neighbor connected as the process title (or the
      number of connected neighbors).

lldpd (0.7.3)
  * Features:
    + DragonFly BSD support.
    + Solaris support (incomplete).
    + LLDP-MED fast start support (thanks to Roopa Prabhu).
    + Provide global statistics through "show statistics summary"
      command (thanks to Roopa Prabhu).
  * Fixes:
    + Fix IPv4/IPv6 address discovery in Linux.

lldpd (0.7.2)
  * Features
    + lldpd can be configured through /etc/lldpd.conf and
      /etc/lldpd.d. All commands accepted by lldpcli are accepted.
    + Lock BPF interfaces before handing them to chrooted process on
      BSD.
    + Limit the number of neighbors for each port to 4 (per protocol).
    + Force CDPv2 protocol with argument `-ccc`.
    + Provide port statistics through "show statistics" command
      (thanks to Roopa Prabhu).
  * Fixes:
    + Driver whitelisting is done before checking if an interface has
      a lower interface in Linux.
    + Expire remote ports and chassis in a timely manner.

lldpd (0.7.1)
  * Features
    + Mac OS X support, sponsored by Xcloud, Mac cloud server hosting
      provider. http://xcloud.me/
    + Upstart and systemd support.
    + Remove Unix socket when there is no process listening.

lldpd (0.7.0)
  * Global changes:
    + FreeBSD support.
    + OpenBSD support.
    + NetBSD support.
    + Detect interface changes.
    + CLI for lldpctl: lldpcli.
  * Other features:
    + Allow to disable LLDP protocol (with `-ll`). In this case, the
      first enabled protocol will be used when no neighbor is detected.
    + Allow to filter debug logs using tokens. Add more debug logs.
    + lldpctl can now output JSON.
    + Use netlink to gather interface information on Linux.
    + Don't use ioctl for bridges anymore on Linux. The configure
      option `--enable-oldies` allow to reenable their uses for
      systems not supporting sysfs.

lldpd (0.6.1)
  * Features:
    + Provide liblldpctl.so, a library to interface with lldpd. The
      documentation is provided through Doxygen. See src/lib/lldpctl.h
      which contains all the exported functions.
    + Make lldpctl uses liblldpctl.so.
    + Add a "watch" option to lldpctl to monitor neighbor changes.
    + Add the possibility to display the current configuration of
      lldpd with lldpctl. Also add the possibility to reset the
      current transmit delay.

lldpd (0.6)
  * Features:
    + Allow lldpctl to display hidden ports.
    + Add a switch to specify interfaces to use to get chassis ID.
    + Support for multiple management addresses and IPv6 management
      addresses. Contributed by João Valverde.
  * Global changes:
    + Switch to libevent. See README.md for details.
    + Partial rewrite of the SNMP part. Less code.
    + Unit tests for SNMP.
    + Major rewrite of the protocol between lldpd and lldpctl. Less
      code.
  * Fixes:
    + Several small SNMP fixes (discovered by unit tests).

lldpd (0.5.7)
 * Fixes:
    + Configure issue with NetSNMP and some linkers
    + Fix infinite loop for the receive part: on certain conditions,
      lldpd will stop sending packets and stop updating local data.

lldpd (0.5.6)
  * Features:
    + Send and receive native VLAN TLV with CDP
    + Add a whitelist for some drivers (currently: dsa and veth)
  * Fixes:
    + Compilation issues with NetSNMP 5.7 (and with earlier versions too)
    + Small optimization of BPF filter

lldpd (0.5.5)
  * Features:
    + Support for PPVID and PI Dot1 TLV, thanks to Shuah Khan.
    + Extend whitelist with possibility to blacklist.
  * Fixes:
    + Key/value output was incorrect when a dot was present in
      interface names. This is fixed but it is preferable to use XML
      output since the parsing is more difficult in this case.
    + Only grab DMI information once. Only uses DMI for x86 platform.
    + Padding issues with socket protocol. This introduces a change in
      the socket protocol!
    + Fix a segfault when neither /etc/os-release nor lsb_release
      are available.

lldpd (0.5.4)
  * Features:
    + Get OS information from /etc/os-release if available. Patch from
      Michael Tremer.
    + Add a flag to specify which interfaces lldpd should listen to.

lldpd (0.5.3)
  * Fixes:
    + Allow root to change configuration of lldpd when lldpctl has suid set.
  * Features:
    + Handle Dot3 POE-MDI TLV (802.3af and 802.3at).
    + Allow to set Dot3 POE-MDI from lldpctl.

lldpd (0.5.2)
  * Features:
    + More flexible smart mode and new default. Manual page has been updated.
    + Add a "receive-only" mode with "-r" switch.

lldpd (0.5.1)
  * Features:
    + Allow to force a protocol even when no peer for this protocol is
      detected.
    + Add a smart mode that allows to discard bogus port information,
      for example CDP packets that are flooded through a switch that
      does not support CDP.
    + Allow to set LLDP-MED network policy from lldpctl, thanks to a patch from
      Philipp Kempgen.
    + Allow to set LLDP-MED POE-MDI from lldpctl.
    + Add a summary of available options in "lldpd -h" and "lldpctl -h",
      thanks to a patch from Jorge Boncompte.
    + Add a new output (keyvalue) for lldpctl.
    + Listen on VLAN using an appropriate BPF filter, VLAN
      decapsulation. Older "listen on vlan" feature is discarded. See
      README for more information on the new feature.
    + Use output of lsb_release if available for system description.

  * Fixes:
    + Ignore interface with no queue. It should filter out interfaces
      like "vnet0" that would fail if we try to send something on them.
    + Don't check CDP checksums (not really a fix but it appears that
      Cisco checksum have some difficult corner cases).

lldpd (0.5.0)

  * Features:
    + lldpd can now handle several systems on the same port. This
      modification also allows to speak to a switch using CDP and LLDP
      for example.
    + The way that lldpd gathers information for each port has been
      abstracted. This should allow to support more systems (BSD for
      examples) or switch cores in the future. Sending/receive support
      is also abstracted.
    + Add "-k" switch to avoid to emit too much information on running
      kernel.
    + Support of ifAlias with kernel >= 2.6.28
    + Lot of portability stuff. lldpd can now be compiled on RHEL
      2.1. Still Linux-only though.
    + Add an option to specify AgentX socket (-X).
    + Add some unit tests
    + lldpctl has been reworked; it is now able to output data in XML
      format for easier parsing. Patches were provided by Andreas
      Hofmeister.

  * Bug fixes:
    + Fix EDP VLAN handling
    + Silent warnings about bridge stuff.
    + Copy /etc/localtime into chroot before starting lldpd daemon to
      ensure correct timestamps for logs.

lldpd (0.4.1)

  * Fix EDP handling when there is no VLAN
  * Fix CDP version to not always be 1
  * Misc fix:
     + incorrect number of arguments for a LLOG_INFO call
     + fix SNMP last change in case this change occurs before start time

lldpd (0.4)

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

lldpd (0.3.2)

  * Fix LLDP-MED support

lldpd (0.3.1)

  * Misc fixes, including memory leaks

lldpd (0.3)

  * Initial support of LLDP-MED
  * Fix for bridge detection (don't send bridge ioctl on random interfaces)
  * For bonded devices, get the real hardware address. For inactive
    slaves, transmit using a random MAC address.

lldpd (0.2.1)

  * Fix a syntax error in manual page
  * Fix open() calls

lldpd (0.2)

  * Add privilege separation
  * Add FDP support
  * Support CDP encapsulated into native VLAN
  * Various fixes

lldpd (0.1)

  * Initial release
