Note to package maintainers: it is important to point out that special care should be taken when porting/testing this release. The plateform-specific code aimed at reading the network configuration (interfaces, routes, etc.) has been entirely rewritten on both Linux and *BSD flavors. Plateforms that were tested include: Linux, OpenBSD, NetBSD, FreeBSD, Darwin. Other plateforms have not been tested, therefore we encourage maintainers to perform additional testing. This has no impact on the other plateforme that we support, such as Windows.

Changelog

General

• [removal]DROP SUPPORT OF PYTHON 2.7

• Python 3.11-3.13 support. The full range of supported Python versions is therefore3.7-3.13
• Improve packaging (pyproject.toml) and version handling. Scapy will now include wheels on pypi.
• We welcome Nils Weiss (polybassa) as a new maintainer !

Main changes

• [major] support for RFC6874-like scope identifiers. This is very useful for multicast IPs as one can now do the following on L3:sr(IP(dst="224.0.0.1%eth0")/..., multi=True)
• [major] using theiface= argument is deprecated on level3 functions (send, sr, sr1), as its behavior was undefined. It remains in use for level2 functions (sendp, srp, srp1). RFC6874-like scope identifiers (see just above) should be used.
• [major] the internals that read the routes and interfaces configurationhave been rewritten on Linux and BSD:
  • on linux, to useRTNETLINK. (this should help on machines that have huge BPG tables)
  • on *BSDs, to usePF_ROUTE.
  • on Linux, NetBSD and FreeBSD, link-local and multicast routes should now properly be loaded
• [new] Windows protocols:
  • DCE/RPC:DCERPC_Client andDCERPC_Server with support forNCACN_IP_TCP andNCACN_NP
  • SMB2/3:
    • Protocol refactor, many more SMB2/3 structures supported
    • Server (class + 'simple' utilsmbserver()) (2.0.2 to 3.1.1)
    • Client (class + interactive CLIsmbclient()) (2.0.2 to 3.1.1)
    • SMB socket, RPC over SMB socket, etc.
  • Kerberos:
    • KerberosSSP to use in SMB/RPC clients/servers, [MS-KILE] variants, SFU and more !
    • Crypto: use cryptography, latest RFC8009, GSS_WrapEx support, typing, etc.
    • Util functions krb_as_req, krb_tgt_req, kpasswd (both modes), etc.
    • Ticketer++: ccache support, ask/renew/resign/edit tickets, etc
  • NTLM:
    • refactor, clean SSP
  • Extensive GSSAPI / SPNEGO support !
  • LDAP
    • Fixes, ASN.1 Windows variation support
    • dclocator, answering machine for "LDAP PING", etc.
    • add a (very) basicLDAP_client (support for various binding mechanisms, encryption, etc.)
• [dep] Support for recentcryptography (42/43.0) versions
• [new] CLI improvements
  • [breaking] Scapy CLI configuration now available in~/.config/scapy/startup.py. This follows XDG variables. (Older~/.scapy_startup.py is now non functional)
  • Support forbpython,ptpython andptipython
• [new] Wireshark extcap interfaces support (load_extcap())
• Automaton:
  • fixes memory usage on Windows
  • support for EOF events
  • spawn() mode, better socket.socket support
• [breaking]StreamSocket changes, support for TCP reassembly, etc. TCPSession(app=True) must no longer be used withStreamSocket. Custom sessions are marked as unstable.
• UseL3RawSocket(6) automatically on the loopback interface on linux
• L3pcapSocket (the default L3 on Windows or when libpcap is used) now follows the same behavior as other L3 sockets when routing
• thesr* class of functions now properly supports sending on multiple interfaces (Windows & Linux)
• performance issues with thesr* class of functions have also been fixed
• manufdb (from wireshark) is now bundled and cached in~/.cache/scapy, as it is no longer shipped as a standalone file in Wireshark.
• Improve builtin answering machines (dnsd,llmnrd,nbnsd,dhcpd...). Addmdnsd for mDNS support
• Fix performance issues with nested*ListFields
• [new]conf.nameservers contains the DNS servers. Also addsdns_resolve()
• [new] SSHv2 layer
• [breaking] ReworkSession objects
• Fix L2 address computation when ARP is used over Ether (intrusive ARPs, bad guessing..)
• [breaking] changesendpfast loop argument to be consistent withsendp
• automaton: improvegraph() to include implicit links
• HTTP:
  • [new] addHTTP_Client andHTTP_Server which support the same SSPs as Windows
  • reworkhttp_client
  • various fixes to reassembly when using TCPSession
• TLS:
  • support for TLS 1.3 post handshake
  • support for EdDSA signatures / keys (ed25519/ed448)
  • various fixes (ffdhe generation, middlebox compat)
  • support choosing of curve, signature algorithms, etc.
• More options supported in DHCP(v6), IPv6, DNS/LLMNR (special thanks to evverx)
• Bluetooth, 802.11: new payloads supported
• IPSEC: AES-NULL-GMAC support
• [breaking] Merge EAPOL contrib into EAP
• fix latex theme
• IKEv2, ISAKMP: NAT traversal support, and other fixes (notify, ...)
• Minor fixes in Netflow, NTP, SCTP, TACACS
• [deprecation] Deprecate Winpcap support on Windows (please use Npcap instead if you are not already using it).
• [removal] Remove ubberlogger.
• cacheget_if_hwaddr for performance
• fixarping without IP
• [new] tcpros layer (ROS 1.1)
• many more fixes
