-From c5590a6821e37f3b29735f55eb0c2b9c0924138c Mon Sep 17 00:00:00 2001
-From: Steffan Karger <steffan.karger@fox-it.com>
-Date: Thu, 20 Nov 2014 13:43:05 +0100
-Subject: [PATCH] Drop too-short control channel packets instead of asserting
- out.
-
-This fixes a denial-of-service vulnerability where an authenticated client
-could stop the server by triggering a server-side ASSERT().
-
-OpenVPN would previously ASSERT() that control channel packets have a
-payload of at least 4 bytes. An authenticated client could trigger this
-assert by sending a too-short control channel packet to the server.
-
-Thanks to Dragana Damjanovic for reporting the issue.
-
-This bug has been assigned CVE-2014-8104.

-Description: When the client sends PUSH_REQUESTS, it waits until the server
- sends PUSH_REPLY. If the server do not have anything to push to the client
- nothing happens. The client will then regularly send new PUSH_REQUESTS until
- it gets an answer, which results in not completing the connection negotiation.
- This patch makes the server send an empty PUSH_REPLY when it has nothing
- more to push to the client.

-+ OpenVPN - eurephia version
-+==============================
-+
-+This is the official OpenVPN version, patched with a
-+patch to implement one needed feature for the eurephia
-+plug-in.
-+
-+All this patch does is to provide the plug-in environment
-+with a variable containing the SHA1 hash of the
-+certificates in use for the session.
-+
-+eurephia is an authentication and security plug-in which
-+enhances the security in OpenVPN even more. It provides
-+user name/password authentication, automatic blacklisting
-+of user account, certificates and IP addresses. In
-+provides in addition automatic updates of the iptables
-+firewall on Linux, with specific iptables profile per
-+user and certificate.
-+
-+For more information about eurephia, have a look at:
-+
-+ http://www.eurephia.net/

-+ * route.c, add_route_ipv6()
-+ - explicitely clear host bits of base address, to be able to more
-+ easily set up "connected" /64 routes on NetBSD+Darwin
-+
-+ - split system-dependent part between Darwin and NetBSD/OpenBSD
-+ (Darwin can use "-iface tun0", NetBSD/OpenBSD get gateway address)
-+
-+ - change Solaris comments from "known-broken" to "unknown"
-+
-+ * tun.c: rework NetBSD tunnel initialization and tun_read() / tun_write()
-+ to work the same way OpenBSD and NetBSD do - tunnel is put into
-+ "multi-af" mode, and all packet read/write activity is prepended by
-+ a 32 bit value specifying the address family.
-+
-+ * TEST SUCCESS: NetBSD 5.0/Sparc64: client-ipv6 with route-ipv6
-+
-+ * TEST SUCCESS: MacOS X 10.5: client-ipv6 with route-ipv6
-+
-+ * (RE-)TEST SUCCESS: Linux/iproute2: server-ipv6
-+ Linux/ifconfig: client-ipv6
-+ FreeBSD 6.3: server-ipv6
-+
-+ * release as patch 20100103-1
-+
-+ * options.c: document all new options in "--help"
-+
-+ * tun.c: fix typo in Solaris-specific section
-+
-+ * socket.h, socket.c: change u_int32_t to uint32_t
-+ (Solaris - and all the rest of the code uses "uintNN" anyway)
-+
-+Mon Jan 4 17:46:58 CET 2010
-+
-+ * socket.c: rework add_in6_addr() to use 32-bit access to struct in6_addr
-+ (Solaris has no 16-bit values in union, but this is more elegant as well)
-+
-+ * tun.c: fix "ifconfig inet6" command for Solaris
-+
-+ * tun.c: make sure "tun0 inet6" is unplumbed first, cleanup leftovers
-+
-+ * route.c: add routes with "metric 0" on solaris, otherwise they just
-+ don't work (someone who understands Solaris might want to fix this).
-+
-+ * Solaris "sort of" works now - ifconfig works, route add does not give
-+ errors, "netstat -rn" looks right, but packets are discarded unless
-+ the routes are installed with "metric 0". So we just use "metric 0"...
-+
-+ * CAVEAT: Solaris "ifconfig ... preferred" interferes with source address
-+ selection. So if there are any active IPv6 interfaces configured with
-+ "preferred", packets leaving out the tunnel will use the wrong source
-+ IPv6 address. Not fixable from within OpenVPN.
-+
-+ * CAVEAT2: Solaris insists on doing DHCPv6 on tun0 interfaces by default,
-+ so DHCPv6 solicitation packets will be seen. Since the server end has
-+ no idea what to do with them, they are a harmless nuisance. Fixable
-+ on the Solaris side via "ndpd.conf" (see ``man ifconfig'').
-+
-+ * release as patch 20100104-1
-+
-+Fri Jan 8 10:00:50 CET 2010
-+
-+ * import into git repository
-+
-+ * options.c: add sanity checks for most typical error cases
-+ (--ifconfig-ipv6-pool configured with no --ifconfig-ipv6, etc)
-+
-+ * options.c: modify get_ipv6_addr() to be more flexible about netbits
-+ (optional now, default to /64) and to return the address-without-netbits
-+ string now (-> for options that want the IPv6 address in printable
-+ form, but without /nn)
-+
-+ * options.c: modify --ifconfig-ipv6 to optionally accept /netbits,
-+ you can do now "ifconfig-ipv6 2001:df8::1/64 2001:df8::2" or just
-+ "ifconfig-ipv6 2001:df8::5 2001:df8::7", defaulting to /64
-+
-+ * options.h: add necessary structure elements for --ifconfig-ipv6-push
-+
-+ * options.c: implement "parse options" side of --ifconfig-ipv6-push
-+
-+Tue Jan 12 22:42:09 CET 2010
-+
-+ * tun.c: in TARGET_NETBSD #ifdef, distinguish between "old" code
-+ (IPv4 only, but unmodified read/write) and "new" code (multi-af,
-+ extra 32 bit AF on read/write of the tun interface) - pre-4.0
-+ NetBSD systems don't have TUNSIFHEAD, no way to have common code.
-+
-+ * TEST SUCCESS: NetBSD 5.0/Sparc64: client-ipv6 with route-ipv6 (v4+v6)
-+
-+ * TEST SUCCESS: NetBSD 3.1/Sparc64: client-ipv6 with route-ipv6 (v4-only)
-+
-+Thu Jan 14 15:41:50 CET 2010
-+
-+ * multi.c: if "--ifconfig-push" is used together with "--ifconfig-ipv6-pool"
-+ and no "--ifconfig-ipv6-push" is seen, issue warning - the current
-+ implementation of pools has IPv6 tied to IPv4, so if v4 does not use
-+ the pool, it breaks for IPv6. Not a *big* problem (since there is
-+ enough v6, just give those users a static v6 address as well), but needs
-+ to be pointed out clearly.
-+
-+ * release as patch 20100114-1
-+
-+Tue Feb 16 14:43:28 CET 2010
-+
-+ * options.c: print "IPv6 payload patch" release date in "--version"
-+
-+ * tun.c: undo change to init_tun() (moving "bool tun" and call to
-+ "is_tun_p2p()" further up) - it wasn't needed and breaks "make check"
-+
-+ * git stuff: rebase on David Sommerseth's openvpn-testing git tree
-+
-+ * release as patch 20100216-1
-+
-+Fri Feb 26 19:59:01 CET 2010
-+
-+ * init.c: initialize tuntap->ipv6 in do_init_tun() (to make sure it's
-+ always initialized early-enough, independent of the sequence of
-+ do_ifconfig()/open_tun() [see ifconfig_order() in tun.h])
-+
-+ * tun.c, init.c: remove "bool ipv6" argument to tuncfg(), open_tun()
-+ and open_tun_generic() - obsoleted by previous change
-+
-+ * tun.c: remove ipv6_support() - original purpose was unclear, and all
-+ current platforms (except linux-very-old) fully support IPv6 now :-)
-+
-+ * tun.c: initial implementation of "netsh" IPv6-ifconfig for Win32
-+
-+ * RE-TEST SUCCESS: Linux/i386/ifconfig, client-tun/net30, v4+v6
-+
-+Sun Feb 28 17:05:57 CET 2010
-+
-+ * tun.c: NetBSD dependent part: correct destroying/re-creation of tun dev

-+ add_route_connected_v6_net()
-+

-+
-+ * tun.c: on close_tun() on MacOS X, need to de-configure "lo0" route for
-+ configured IPv6 address
-+
-+ * RE-TEST SUCCESS: MacOS X (10.5)/i386: client-tun/net30, v4+v6
-+
-+ * route.c: implement ipv6 route adding / deletion via "netsh" for WIN32
-+
-+ * TEST FAIL: Windows XP fails, because the tun/tap driver does not
-+ forward IPv6 frames kernel->userland if in "tun" mode
-+
-+ * options.c: set IPv6 version to 20100228-1

-+ installed as route-nexthop by OpenVPN.exe) get answered locally
-+
-+ * TEST SUCCESS: WindowsXP/32bit: client-tun/net30, v4+v6

-+known issues for IPv6 payload support in OpenVPN
-+-----------------------------------------------
-+
-+1.) "--topology subnet" doesn't work together with IPv6 payload on FreeBSD
-+ (verified for FreeBSD server, Linux/ifconfig client, problems
-+ with ICMP6 neighbor solicitations from BSD not being answered by Linux)
-+
-+2.) NetBSD IPv6 support doesn't work
-+ ("connected" route is not auto-created, "route-ipv6" adding fails)
-+
-+ * fixed, 3.1.10 *
-+
-+3.) route deletion for IPv6 routes is not yet done
-+
-+ * fixed for configured routes, 3.1.10 *
-+ * missing for manual-ifconfig-connected (NetBSD, Darwin, Win32)
-+
-+4.) do "ifconfig tun0 inet6 unplumb" or "ifconfig tun0 destroy" for
-+ Solaris, *BSD, ... at program termination time, to clean up leftovers
-+ (unless tunnel persistance is desired).
-+
-+ For Solaris, only the "ipv6 tun0" is affected, for the *BSDs all tun0
-+ stay around.
-+
-+4a.) deconfigure IPv6 on tun interface on session termination, otherwise
-+ one could end up with something like this (on NetBSD):
-+
-+tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
-+ inet 10.9.0.18 -> 10.9.0.17 netmask 0xffffffff
-+ inet6 fe80::a00:20ff:fece:d299%tun0 -> prefixlen 64 scopeid 0x3
-+ inet6 2001:608:4:eff::2000:3 -> prefixlen 64
-+ inet6 2001:608:4:eff::1:3 -> prefixlen 64
-+
-+ (pool was changed, previous address still active on tun0, breakage)
-+
-+ * semi-fixed for NetBSD, 28.2.10, always do tun0 destroy / tun0 create
-+ before actual ifconfig -- tunnel still lingers after OpenVPN quits
-+
-+4b.) verify this - on FreeBSD, tun0 is auto-destroyed if created by
-+ opening /dev/tun (and lingers if created by "ifconfig tun0 create")
-+
-+ -> use for persistant tunnels on not-linux?
-+
-+5.) add new option "ifconfig-ipv6-push"
-+ (per-client static IPv6 assignment, -> radiusplugin, etc)
-+
-+ * implemented, 14.1.10 *
-+
-+6.) add new option "route-ipv6-gateway"
-+
-+7.) add "full" gateway handling for IPv6 in route.c
-+ (right now, the routes are just sent down the tun interface, if the
-+ operating system in questions supports that, without care for the
-+ gateway address - which does not work for gateways that are supposed
-+ to point elsewhere. Also, it doesn't work for TAP interfaces.
-+
-+8.) full IPv6 support for TAP interfaces
-+ (main issue should be routes+gateway - and testing :-) )
-+
-+ test 2010/09/24: TAP itself works on linux/ifconfig+iproute2, but
-+ route-via-tap doesn't work at all (route points to "tap0" which fails)
-+
-+17:51:14.075412 fe:ab:6e:c5:53:71 > 33:33:ff:00:00:01, ethertype IPv6 (0x86dd), length 86: 2001:608:4:a053::1:0 > ff02::1:ff00:1: ICMP6, neighbor solicitation, who has 2001:608:4:a001::1, length 32
-+
-+ how is iroute-via-tap supposed to work??
-+
-+9.) verify that iroute-ipv6 and route-ipv6 interact in the same way as
-+ documented for iroute/route:
-+
-+ A's subnet, OpenVPN must push this route to all clients
-+ EXCEPT for A, since the subnet is already owned by A.
-+ OpenVPN accomplishes this by not
-+ not pushing a route to a client
-+ if it matches one of the client's iroutes.
-+
-+10.) extend "ifconfig-ipv6" to handle specification of /netbits, pushing
-+ of /netbits, and correctly ifconfig'ing this
-+ (default, if not specified: /64)
-+
-+11.) do not add ipv6-routes if tun-ipv6 is not set - complain instead
-+
-+ * done * 12.1.10
-+
-+12.) handle incoming [::] and [fe80:...] packets in tun-p2mp MULTI mode
-+ (most likely those are DAD packets)
-+ silently ignore DAD?
-+ Or accept-and-forward iff (multicast && client2client)?
-+ handle NS/NA
-+
-+13.) from Martin List-Petersen:
-+
-+ One thing, and I guess this requires modifications in
-+ network-manager-openvpn: It also works, BUT ignores "push
-+ route-ipv6-gateway" and "push route-ipv6 ...." (obviously routes pushed
-+ from the server) entirely.
-+
-+14.) from ##openvpn-discussion:
-+
-+ new features should be #ifdef'ed
-+
-+ (check whether this is feasible at all)
-+
-+15.) IPv6 related environment variables
-+
-+ - document all of them in openvpn.8
-+ - make sure that all existing IPv4 stuff has IPv6 counterparts
-+
-+16.) OpenBSD
-+ - implement ifconfig/route for IPv6
-+ - revert ifconfig/open_tun order to "normal" (separate commit!!!)
-+ (openvpn-devel, Subject: OpenBSD)
-+ - test
-+
-+17.) client-option (Elwood)
-+ - ignore-v6-push-options yes/no
-+ - ignore-v6-route-push ("as for IPv4 routes")
-+
-+18.) fail-save? "what if 'ip -6 addr add' fails" -> fail, or fallback to v4?
-+ (-> recomment setting "ignore-v6-push-options yes")
-+
-+19.) safety check: if connecting over IPv6 (v6 transport) and the pushed
-+ route-ipv6 network encompasses the server IPv6 address, make sure
-+ we at least log a warning (until we can fiddle with external routing
-+ to make this work correctly).
-+
-+20.) show "route add" / "route delete" commands for IPv6 in log file
-+ (we show the "ifconfig" commands, so why not the routes?)
-+
-+ 2010-08-07: this is a null-feature - it's already there, but with
-+ different debug level (M_INFO vs. D_ROUTE) so user
-+ didn't notice
-+
-+21.) enable ipv6-only server operations
-+ - decouple ipv6 pool handling from ipv4 pool
-+ - make sure Rest of OpenVPN doesn't assume "there will always be IPv4"
-+
-+22.) implement --learn-address for IPv6
-+
-+23.) FreeBSD 8 seems to require explicit setting of the "ifconfig" IPv6
-+ route, while FreeBSD 6+7 don't --> more testing, and code fix
-+
-+ workaround for the time being: just add
-+
-+ server-ipv6 2001:608:4:a051::/64
-+ route-ipv6 2001:608:4:a051::/64
-+
-+ to the config
-+
-+ (problem + workaround applies both to tun and tap style devices)

-+
-+OpenVPN-2.1 over UDP6/TCP6 README for ipv6-0.4.x patch releases:
-+( --udp6 and --tcp6-{client,server} )
-+
-+* Availability
-+ Source code under GPLv2 from http://github.com/jjo/openvpn-ipv6
-+
-+ Distro ready repos/packages:
-+ o Debian sid official repo, by Alberto Gonzalez Iniesta,
-+ starting from openvpn_2.1~rc20-2
-+ o Gentoo official portage tree, by Marcel Pennewiss:
-+ - https://bugs.gentoo.org/show_bug.cgi?id=287896
-+ o Ubuntu package, by Bernhard Schmidt:
-+ - https://launchpad.net/~berni/+archive/ipv6/+packages
-+ o Freetz.org, milestone freetz-1.2
-+ - http://trac.freetz.org/milestone/freetz-1.2
-+
-+* Status:
-+ o OK:
-+ - upd6,tcp6: GNU/Linux, win32, openbsd-4.7, freebsd-8.1
-+ - udp4->upd6,tcp4->tcp6 (ipv4/6 mapped): GNU/Linux
-+ (gives a warning on local!=remote proto matching)
-+ o NOT:
-+ - win32: tcp4->tcp6 (ipv4/6 mapped) fails w/connection refused
-+ o NOT tested:
-+ - mgmt console
-+
-+* Build setup:
-+ ./configure --enable-ipv6 (by default)
-+
-+* Usage:
-+ For IPv6 just specify "-p upd6" an proper IPv6 hostnames, adapting the example
-+ from man page ...
-+
-+ On may:
-+ openvpn --proto udp6 --remote <june_IPv6_addr> --dev tun1 \
-+ --ifconfig 10.4.0.1 10.4.0.2 --verb 5 --secret key
-+
-+ On june:
-+ openvpn --proto udp6 --remote <may_IPv6_addr> --dev tun1 \
-+ --ifconfig 10.4.0.2 10.4.0.1 --verb 5 --secret key
-+
-+ Same for --proto tcp6-client, tcp6-server.
-+
-+* Main code changes summary:
-+ - socket.h: New struct openvpn_sockaddr type that holds sockaddrs and pktinfo,
-+ (here I omitted #ifdef USE_PF_xxxx, see socket.h )
-+
-+ struct openvpn_sockaddr {
-+ union {
-+ struct sockaddr sa;
-+ struct sockaddr_in in;
-+ struct sockaddr_in6 in6;
-+ } addr;
-+ };
-+
-+ struct link_socket_addr
-+ {
-+ struct openvpn_sockaddr local;
-+ struct openvpn_sockaddr remote;
-+ struct openvpn_sockaddr actual;
-+ };
-+
-+ PRO: allows simple type overloading: local.addr.sa, local.addr.in, local.addr.in6 ... etc
-+ (also local.pi.in and local.pi.in6)
-+
-+ - several function prototypes moved from sockaddr_in to openvpn_sockaddr
-+ - several new sockaddr functions needed to "generalize" AF_xxxx operations:
-+ addr_copy(), addr_zero(), ...etc
-+ proto_is_udp(), proto_is_dgram(), proto_is_net()

-+
-+* All platforms:
-+ o mgmt console: as currently passes straight in_addr_t bits around
-+
-+ o make possible to get AF from getaddrinfo() answer, ie allow openvpn to
-+ use ipv4/6 if DNS returns A/AAAA without specifying protocol.
-+ Hard: requires deep changes in initialization/calling logic
-+
-+ o use AI_PASSIVE
-+
-+ o the getaddr()/getaddr6() interface is not prepared for handling socktype
-+ "tagging", currently I abuse the sockflags bits for getting the ai_socktype
-+ downstream.
-+
-+ o implement comparison for mapped addesses: server in dual stack
-+ listening IPv6 must permit incoming streams from allowed IPv4 peer,
-+ currently you need to pass eg: --remote ffff::1.2.3.4
-+
-+ o do something with multi mode learn routes, for now just ignoring
-+ ipv6 addresses seems the most sensible thing to do, because there's
-+ no support for intra-tunnel ipv6 stuff.
-+
-+* win32:
-+ o find out about mapped addresses, as I can't make it work
-+ with bound at ::1 and connect to 127.0.0.1
-+
-+* N/A:
-+ o this is ipv6 *endpoint* support, so don't expect "ifconfig6"-like
-+ support in this patch
