Import libpcap-1.10.6 (previous was 1.10.5)

Tuesday, December 30, 2025 / The Tcpdump Group
  Summary for 1.10.6 libpcap release
    General:
      Fix "tcpdump -i <n>" for something-only libpcap builds.
      gencode: Fix an undefined behavior in gen_mcode().
      gencode: Add a missing free() in gen_scode().
      Remove "DLT_" from the descriptions of two dlt_choices[] entries.
      Report the size of time_t in the version string.
      Validate remote capture source strings better.
      CVE-2025-11961: Fix OOBR and OOBW in pcap_ether_aton().
    Source code:
      Remove some unneeded includes.
      pcapint_find_function() changed to return "void *" to avoid
        warnings.
      Clean up code that computes the length of a netmask.
      Mind netmap support in pcap_lib_version().
    Link-layer types:
      Add LINKTYPE_ETW/DLT_ETW.
      Add LINKTYPE_NETANALYZER_NG/DLT_NETANALYZER_NG (pull request
        #1008).
      Add LINKTYPE_ZBOSS_NCP/DLT_ZBOSS_NCP.
      Add LINKTYPE_USB_2_0_LOW_SPEED/DLT_USB_2_0_LOW_SPEED,
        LINKTYPE_USB_2_0_FULL_SPEED/DLT_USB_2_0_FULL_SPEED,
        LINKTYPE_USB_2_0_HIGH_SPEED/DLT_USB_2_0_HIGH_SPEED
      Add LINKTYPE_AUERSWALD_LOG/DLT_AUERSWALD_LOG.
      Add LINKTYPE_ZWAVE_TAP/DLT_ZWAVE_TAP.
      Add LINKTYPE_SILABS_DEBUG_CHANNEL/DLT_SILABS_DEBUG_CHANNEL.
      Add LINKTYPE_FIRA_UCI/DLT_FIRA_UCI.
      Rename LINKTYPE_IPMB_LINUX/DLT_IPMB_LINUX to
        LINKTYPE_I2C_LINUX/DLT_I2C_LINUX, as it's really just an
        encapsulation of I2C, and is also being used for HDMI DDC.
        Keep DLT_IPMB_LINUX around as a #define for backwards
        compatibility.
      Add LINKTYPE_MDB/DLT_MDB.
      Add LINKTYPE_DECT_NR/DLT_DECT_NR.
      Add LINKTYPE_EDK2_MM/DLT_EDK2_MM.
      Add LINKTYPE_DEBUG_ONLY/DLT_DEBUG_ONLY.
    Packet filtering:
      Make the chunk allocator's alignment more general and
        platform-independent.
      IEEE 802.11: Fix three undefined behaviors in grammar.y.
      Fix IPv4 multicast filtering to only include 224.0.0.0/4.
      Fix "(arp|rarp) host NAME" to ignore IPv6 quietly.
      Fix ARCnet address parsing.
    Linux:
      Fix check for mac80211 phydev.
      Don't create monitor-mode interface if we're capturing on one.
      Expand the table of DSA tag types to include all current types.
      Fix an error message when deleting a monN interface.
      Fix returning PCAP_ERROR_RFMON_NOTSUP with libnl.
      Fix the error message when capure permission is denied.
      Fix the error message if PF_PACKET sockets aren't supported.
      Fix a file descriptor leak in an error case (pull request #1537).
      Handle errors better when checking for a DSA-tagged interface.
      Use DLT_DEBUG_ONLY for DSA tags that do not [yet] have a better support.
    FreeBSD:
      Fix detection and enabling of zero-copy support.
      Fix errors in the zero-copy code.
    Solaris:
      Fix not to ignore logical interfaces in fad-gifc.c and
        fad-glifc.c.
      Fix attempts to open all-numeric device names with DLPI to
        return "no such device".
      Fix error returns and messages when an interface has no DLPI
        device.
      Return all interfaces in pcap_findalldevs() even if they can't be
        opened.
    HP-UX:
      Fix attempts to open all-numeric device names to return
        "no such device".
      Fix error message if there's no /dev/dlpi device.
      Return all interfaces in pcap_findalldevs() even if they can't be
        opened.
    Windows:
      Fix filtering for VLAN-tagged frames.
      Add support for Npcap's nanosecond-resolution time stamps in
        captures.
      CVE-2025-11964: Fix a bug in error message character encoding mapping
        from UTF-16 to UTF-8.
      Check at create time whether the NPF driver supports nanosecond
        precision.
    D-Bus:
      Fix message leak.
    Capture file writing:
      Don't close the output stream if it's stdout, just flush it.
    Documentation:
      Explicitly document that closing a pcap_t for a savefile opened
        with pcap_fopen_offline() will close the standard I/O stream.
    Building and testing:
      Makefile.in: Include instrument-functions.c in the release tarball.
      CMake: Fix libnl usage with pkg-config.
      CMake: Fix build with CMake 3.31.
      CI: Report CMake version in builds.
      CI: Visual Studio 2022 builds added, including ARM64 builds;
        Visual Studio 2015 builds dropped.
      Don't build with sslutils.c if we don't have a TLS library.
      Build on Windows with a newer version of OpenSSL.
      CMake: generalize handling of non-x86 Windows architectures.
      CI: use the -A flag for all Visual Studio generators.
      Remove the fuzzing props from the release tarball.
      Autoconf: Use AC_SYS_YEAR2038_RECOMMENDED when possible if the
        environment variable BUILD_YEAR2038 = yes (via autogen.sh)
      DPDK: don't enable it by default.
      Update Npcap SDK to 1.15.
      autogen.sh: Allow to configure Autoconf warnings.
      autogen.sh: Delete all trailing blank lines at end of configure.

 run `./autogen.sh` (a shell script). The autogen.sh script will
 build the `configure` and `config.h.in` files.
 
+* If you build on a Linux 32-bit system, with Autoconf version >= 2.72
+and GNU C Library version >= 2.34, run `export BUILD_YEAR2038=yes`
+before running `./autogen.sh` to build with 64-bit time_t (Y2038-safe).

 On some system, you may need to set the `AUTORECONF` variable, like:
 `AUTORECONF=autoreconf-2.69 ./autogen.sh`
 to select the `autoreconf` version you want to use.
