Hook OSX-specific syscalls + ----------------------------- + Mac OXS has a number of variants of each syscall. This patch adds + hooks for the following OSX variants: + + select() : select_unix2003() + select_nocancel() + select_darwinextsn_nocancel() + select_darwinextsn() + + poll(), connect(), sendmsg(), sendto(), close(): *_unix2003(), + *_nocancel() + getpeername(): *_unix2003() + + 2. Add Hooking Macros + -------------------- + Move the symbol loading and checking out to macros of the form + [syscall]_PATCH: + + PATCH_SELECT, PATCH_CONNECT, PATCH_CLOSE, PATCH_POLL, + PATCH_GETPEERNAME, PATCH_SENDTO, PATCH_SENDMSG + + Rename the syshooks to functions of the form *_guts(). + + 3. Miscellaneous + ---------------- + Add NONSTD_SOURCE define for Mac OSX.Defining _NONSTD_SOURCE + causes library and kernel calls to behave as closely + to Mac OS X 10.3's library and kernel calls as possible. + + Use socklen_t instead of int. + + Move get_environment() and get_config() to tsocks_init(), + rather than calling adhoc in the syscalls. + + Differentiate between EISCONN and EINPROGRESS errors in + connect(). + + Original Patch from Alex Rosenberg <alex(a)ohmantics.com> + http://code.google.com/p/torsocks/issues/detail?id=2#c11 + + o Patch torsocks.in for Mac OSX + Patch from alexr(a)ohmantics.com + Mac OSX uses the DYLD_INSERT_LIBRARIES and DYLD_FORCE_FLAT_NAMESPACE + environment variables to enable/perform syscall-hooking. Also, on + Mac OSX dynamically linked libraries use the '*.dylib' extension + rather than '*.so'. Alex's patches for torsocks.in and configure.in + ensure that we use the appropriate values for Max OSX. Ideally, we + wouldn't export DYLD_FORCE_FLAT_NAMESPACE on non-Mac OSX platforms + but it is harmless to do so. We'll leave that for another day. + The patch also fixes up the sed reg-exp to interpret the 'echo + DYLD_INSERT_LIBRARIES' output as well as that from LD_PRELOAD. + + o Whitespace cleanup in parser.c + + o Add linker checks for Mac OSX. Patch from alexr(a)ohmantics.com + + o Move MAP_ANONYMOUS to common.h + + o LD_PRELOAD is ignored for binaries where setuid/gid is used. As used, + torsocks doesn't detect this, which means that it provides a false sense + of security when running these types of executables. + Added logic that detects setuid/setgid programs and fails early with an + error message. + Further reorganized the file to simplify flow and improve command line + argument handling. + Patch by Marcus Griep <marcus(a)griep.us> + + o remove aclocal.m4 + + o BSD build patch from grarpamp. See http://code.google.com/p/torsocks/issues/detail?id=4. + + o Replace TSOCKS_* environment variables with TORSOCKS_* equivalents as per man page. + + o Remove superfluous include. + + o Fix compilcation on Mac OSX. See http://code.google.com/p/torsocks/issues/detail?id=2 + + o Expand reject message for UDP and ICMP requests + Torsocks 1.0-delta 2009-02-XX Robert Hogan <robert(a)roberthogan.net> o Fix segfault when address supplied for getaddrinfo is null.

Introduction - - The use of network firewalls, systems that effectively isolate an - organizations internal network structure from an exterior network, - such as the INTERNET is becoming increasingly popular. These - firewall systems typically act as application-layer gateways between - networks, usually offering controlled TELNET, FTP, and SMTP access. - With the emergence of more sophisticated application layer protocols - designed to facilitate global information discovery, there exists a - need to provide a general framework for these protocols to - transparently and securely traverse a firewall. - - - - - -Leech, et al Standards Track [Page 1] - -RFC 1928 SOCKS Protocol Version 5 March 1996 - - - There exists, also, a need for strong authentication of such - traversal in as fine-grained a manner as is practical. This - requirement stems from the realization that client-server - relationships emerge between the networks of various organizations, - and that such relationships need to be controlled and often strongly - authenticated. - - The protocol described here is designed to provide a framework for - client-server applications in both the TCP and UDP domains to - conveniently and securely use the services of a network firewall. - The protocol is conceptually a "shim-layer" between the application - layer and the transport layer, and as such does not provide network- - layer gateway services, such as forwarding of ICMP messages. - -2. Existing practice - - There currently exists a protocol, SOCKS Version 4, that provides for - unsecured firewall traversal for TCP-based client-server - applications, including TELNET, FTP and the popular information- - discovery protocols such as HTTP, WAIS and GOPHER. - - This new protocol extends the SOCKS Version 4 model to include UDP, - and extends the framework to include provisions for generalized - strong authentication schemes, and extends the addressing scheme to - encompass domain-name and V6 IP addresses. - - The implementation of the SOCKS protocol typically involves the - recompilation or relinking of TCP-based client applications to use - the appropriate encapsulation routines in the SOCKS library. - -Note: - - Unless otherwise noted, the decimal numbers appearing in packet- - format diagrams represent the length of the corresponding field, in - octets. Where a given octet must take on a specific value, the - syntax X'hh' is used to denote the value of the single octet in that - field. When the word 'Variable' is used, it indicates that the - corresponding field has a variable length defined either by an - associated (one or two octet) length field, or by a data type field. - -3. Procedure for TCP-based clients - - When a TCP-based client wishes to establish a connection to an object - that is reachable only via a firewall (such determination is left up - to the implementation), it must open a TCP connection to the - appropriate SOCKS port on the SOCKS server system. The SOCKS service - is conventionally located on TCP port 1080.

The supplied BND.ADDR is often - different from the IP address that the client uses to reach the SOCKS - server, since such servers are often multi-homed. It is expected - that the SOCKS server will use DST.ADDR and DST.PORT, and the - client-side source address and port in evaluating the CONNECT - request. - -BIND - - The BIND request is used in protocols which require the client to - accept connections from the server. FTP is a well-known example, - which uses the primary client-to-server connection for commands and - status reports, but may use a server-to-client connection for - transferring data on demand (e.g. LS, GET, PUT). - - It is expected that the client side of an application protocol will - use the BIND request only to establish secondary connections after a - primary connection is established using CONNECT. In is expected that - a SOCKS server will use DST.ADDR and DST.PORT in evaluating the BIND - request. - - Two replies are sent from the SOCKS server to the client during a - BIND operation. The first is sent after the server creates and binds - a new socket. The BND.PORT field contains the port number that the - SOCKS server assigned to listen for an incoming connection. The - BND.ADDR field contains the associated IP address. The client will - typically use these pieces of information to notify (via the primary - or control connection) the application server of the rendezvous - address. The second reply occurs only after the anticipated incoming - connection succeeds or fails. - - - - - -Leech, et al Standards Track [Page 6] - -RFC 1928 SOCKS Protocol Version 5 March 1996 - - - In the second reply, the BND.PORT and BND.ADDR fields contain the - address and port number of the connecting host. - -UDP ASSOCIATE - - The UDP ASSOCIATE request is used to establish an association within - the UDP relay process to handle UDP datagrams. The DST.ADDR and - DST.PORT fields contain the address and port that the client expects - to use to send UDP datagrams on for the association. The server MAY - use this information to limit access to the association. If the - client is not in possesion of the information at the time of the UDP - ASSOCIATE, the client MUST use a port number and address of all - zeros. - - A UDP association terminates when the TCP connection that the UDP - ASSOCIATE request arrived on terminates. - - In the reply to a UDP ASSOCIATE request, the BND.PORT and BND.ADDR - fields indicate the port number/address where the client MUST send - UDP request messages to be relayed. - -Reply Processing - - When a reply (REP value other than X'00') indicates a failure, the - SOCKS server MUST terminate the TCP connection shortly after sending - the reply. This must be no more than 10 seconds after detecting the - condition that caused a failure. - - If the reply code (REP value of X'00') indicates a success, and the - request was either a BIND or a CONNECT, the client may now start - passing data. If the selected authentication method supports - encapsulation for the purposes of integrity, authentication and/or - confidentiality, the data are encapsulated using the method-dependent - encapsulation. Similarly, when data arrives at the SOCKS server for - the client, the server MUST encapsulate the data as appropriate for - the authentication method in use. - -7. Procedure for UDP-based clients - - A UDP-based client MUST send its datagrams to the UDP relay server at - the UDP port indicated by BND.PORT in the reply to the UDP ASSOCIATE - request. If the selected authentication method provides - encapsulation for the purposes of authenticity, integrity, and/or - confidentiality, the datagram MUST be encapsulated using the - appropriate encapsulation. Each UDP datagram carries a UDP request - header with it: - - - - - -Leech, et al Standards Track [Page 7] - -RFC 1928 SOCKS Protocol Version 5 March 1996 - - - +----+------+------+----------+----------+----------+ - |RSV | FRAG | ATYP | DST.ADDR | DST.PORT | DATA | - +----+------+------+----------+----------+----------+ - | 2 | 1 | 1 | Variable | 2 | Variable | - +----+------+------+----------+----------+----------+ - - The fields in the UDP request header are: - - o RSV Reserved X'0000' - o FRAG Current fragment number - o ATYP address type of following addresses: - o IP V4 address: X'01' - o DOMAINNAME: X'03' - o IP V6 address: X'04' - o DST.ADDR desired destination address - o DST.PORT desired destination port - o DATA user data - - When a UDP relay server decides to relay a UDP datagram, it does so - silently, without any notification to the requesting client. - Similarly, it will drop datagrams it cannot or will not relay. When - a UDP relay server receives a reply datagram from a remote host, it - MUST encapsulate that datagram using the above UDP request header, - and any authentication-method-dependent encapsulation. - - The UDP relay server MUST acquire from the SOCKS server the expected - IP address of the client that will send datagrams to the BND.PORT - given in the reply to UDP ASSOCIATE. It MUST drop any datagrams - arriving from any source IP address other than the one recorded for - the particular association. - - The FRAG field indicates whether or not this datagram is one of a - number of fragments. If implemented, the high-order bit indicates - end-of-fragment sequence, while a value of X'00' indicates that this - datagram is standalone. Values between 1 and 127 indicate the - fragment position within a fragment sequence. Each receiver will - have a REASSEMBLY QUEUE and a REASSEMBLY TIMER associated with these - fragments. The reassembly queue must be reinitialized and the - associated fragments abandoned whenever the REASSEMBLY TIMER expires, - or a new datagram arrives carrying a FRAG field whose value is less - than the highest FRAG value processed for this fragment sequence. - The reassembly timer MUST be no less than 5 seconds. It is - recommended that fragmentation be avoided by applications wherever - possible. - - Implementation of fragmentation is optional; an implementation that - does not support fragmentation MUST drop any datagram whose FRAG - field is other than X'00'. - - - -Leech, et al Standards Track [Page 8] - -RFC 1928 SOCKS Protocol Version 5 March 1996 - - - The programming interface for a SOCKS-aware UDP MUST report an - available buffer space for UDP datagrams that is smaller than the - actual space provided by the operating system: - - o if ATYP is X'01' - 10+method_dependent octets smaller - o if ATYP is X'03' - 262+method_dependent octets smaller - o if ATYP is X'04' - 20+method_dependent octets smaller - -8. Security Considerations - - This document describes a protocol for the application-layer - traversal of IP network firewalls. The security of such traversal is - highly dependent on the particular authentication and encapsulation - methods provided in a particular implementation, and selected during - negotiation between SOCKS client and SOCKS server. - - Careful consideration should be given by the administrator to the - selection of authentication methods. - -9.
