./net/libpcap, System-independent interface for user-level packet capture

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 1.10.3, Package name: libpcap-1.10.3, Maintainer: pkgsrc-users

This is libpcap, a system-independent interface for user-level packet
capture. libpcap provides a portable framework for low-level network
monitoring. Applications include network statistics collection,
security monitoring, network debugging, etc. Since almost every
system vendor provides a different interface for packet capture, and
since we've developed several tools that require this functionality,
we've created this system-independent API to ease in porting and to
alleviate the need for several system-dependent packet capture modules
in each application.

Saturday, December 31, 2022 / The Tcpdump Group
  Summary for 1.10.2 libpcap release
    Source code:
      Use __builtin_unreachable() in PCAP_UNREACHABLE.
      Use AS_HELP_STRING macro instead of AC_HELP_STRING in the
        configure scripts, to avoid deprecation warnings.
      Change availability tags in pcap.h to make it easier to
        arrange for it to be used in Darwin releases.
      Use AS_HELP_STRING for --enable-remote.
      Fix some formatting string issues found by cppcheck.
      Various small code and comment cleanups.
      Use PCAP_ERROR (defined as -1) rather than explicit -1 for
        functions the documentation says return PCAP_ERROR.
      Remove unused code from the filter compiler.
      Use _declspec(deprecated(msg)) rather than __pragma(deprecated)
        for Windows deprecation warnings, so the message that was
        specified shows up.
      diag-control.h: define PCAP_DO_PRAGMA() iff we're going to use it.
      Use "%d" to print some signed ints.
      Use the Wayback Machine for a removed document in a comment.
      Add some const qualifiers.
      RDMA: Use PRIu64 to print a uint64_t.
    "Dead" pcap_ts from pcap_open_dead() and ..._with_tstamp_precision():
        Don't crash if pcap_breakloop() is called.
      Fix pcap_dispatch() to return number of packets processed, rather
        than 0, even at EOF.
      If we get an error writing the packet header, don't write the
        packet data.
      Put PFLOG UID and PID values in the header into host byte order
        when reading a LINKTYPE_PFLOG file.
      Put CAN ID field in CAN pseudo-headers for LINUX_SLL2, as we do

        denied" errors.
      SITA: Fix a typo in a variable name.
    Packet filtering:
      Get PFLOG header length from the length value in the header.
      Support all the direction, reason, and action types supported by
        all systems that support PFLOG.

        when capturing.
      Correctly compute the "real" length for isochronous USB transfers.
      Don't have an eventfd descriptor open in non-blocking mode, so as

    BPF capture (*BSD, macOS, AIX, Solaris 11):
      Fix case where a device open might fail, rather than falling back
        to a smaller buffer size, when the initial buffer size is too

    README.linux.md isn't Markdown, rename it just README.linux.
    Support reading version 1.2, which some writers produce, and which
        is the same as 1.0 (some new block types were added, but
        that's not sufficient reason to bump the minor version number,
        as code that understands those new block types can handle them
        in a 1.0 file)
    Drop support for text-mode USB captures, as we require a 2.6.27
        or later kernel (credit to Chaoyuan Peng for noting the
        sscanf vulnerabilities in the text-mode code that got me to
        realize that we didn't need this code any more)
    Bluetooth: fix non-blocking mode.
    Don't assume that all compilers used to build for Linux support
        the __atomic builtins
    Add more information in "interface disappeared" error messages, in

  Label most APIs by the first release in which they're available
  Fix some memory leaks, including in pcap_compile()

  Fix some thread safety issues
  pcap_findalldevs(): don't sort interfaces by unit number
  Always return a list of supported time-stamp types, even if only
      host time stamps are supported
  Increase the maximum snaplen for LINKTYPE_USBPCAP/DLT_USBPCAP
  Report the DLT description in error messages

      Fix some issues found by cppcheck.
      Add some overflow checks in the optimizer
      Support rpcap-over-TLS
      Redo protocol version negotiation to avoid problems with old
          servers (it still works with servers using the old negotiation,
          as well as servers not supporting negotiation)
      Error handling cleanups
      Add some new authentication libpcap error codes for specific
      Fix some inetd issues in rpcapd
      Fix rpcapd core dumps with invalid configuration file
      On UN*X, don't have rpcapd tell the client why authentication
          failed, so a brute-force attacker can't distinguish between
          "unknown user name" and "known user name, wrong \

          down but is still present
      Set socket protocol only after packet ring configured,
          reducing bogus packet drop reports
      Get ifdrop stats from sysfs.
      When adjusting BPF programs, do not subtract the
          SLL[2]_HDR_LEN if the location is negative (special metadata
          offset), to preserve references to metadata; see

      Have pcap_breakloop() forcibly break out of a sleeping
          capture loop
      Add support for DSA data link types
