Fixes cid 501 and 502.
|
|
|
|
Found by katmagic. Bugfix on the #3460 branch, not yet in any release.
|
|
Remove environ declaration.
Use ORPort->value. And it's a string.
Make tmp a char *.
|
|
|
|
Otherwise, on Windows, gcc will warn about the function being unused
|
|
|
|
This avoids a warning from gcc (comparison between signed and unsigned
integer expressions [-Werror=sign-compare]), under Windows

The client's anonymity when accessing a non-HS address in tor2web-mode
would be easily nuked by inserting an inline image with a .onion URL, so
don't even pretend to access non-HS addresses through Tor.
|
|
|
|
The Tor2webMode torrc option is still required to run a Tor client in
'tor2web mode', but now it can't be turned on at runtime in a normal build
of Tor. (And a tor2web build of Tor can't be used as a normal Tor client,
so we don't have to worry as much about someone distributing packages with
this particular pistol accessible to normal users.)

- Link in libws32 and libiphlpapi, needed for libnatpmp (both in
./configure and when compiling tor-fw-helper-natpmp.c)
- Define STATICLIB under Windows, to allow tor-fw-helper-natpmp.c to link
- Don't include arpa/inet.h which isn't present in Mingw32 and doesn't
appear to be needed on either Windows or MacOS X

This resolves a loop warning on "MapAddress *.example.com
example.com", makes the rewrite log messages correct, and fixes the
behavior of "MapAddress *.a *.b" when just given "a" as an input.
|
|
MapAddress *.torproject.org torproject.org would have been interpreted
as a map from a domain to itself, and would have cleared the mapping.
Now we require not only a match of domains, but of wildcards.
|
|
Incidentally, we've got 30969 lines in master with a comma
in them, of which 1995 have a comma followed by a non-newline,
non-space character. So about 93% of our commas are right,
but we have a substantial number of "crowded" lines.
|
|
It might be nice to support this someday, but for now it would fail
with an infinite remap cycle. (If I say "remap * *.foo.exit",
then example.com ->
example.com.foo.exit ->
example.com.foo.exit.foo.exit ->
example.com.foo.exit.foo.exit.foo.exit -> ...)
|

In this new representation for wildcarded addresses, there are no
longer any 'magic addresses': rather, "a.b c.d", "*.a.b c.d" and
"*.a.b *.c.d" are all represented by a mapping from "a.b" to "c.d". we
now distinguish them by setting bits in the addressmap_entry_t
structure, where src_wildcard is set if the source address had a
wildcard, and dst_wildcard is set if the target address had a
wildcard.
This lets the case where "*.a.b *.c.d" or "*.a.b c.d" remap the
address "a.b" get handled trivially, and lets us simplify and improve
the addressmap_match_superdomains implementation: we can now have it
run in O(parts of address) rather than O(entries in addressmap).

1. Only allow '*.' in MapAddress expressions. Ignore '*ample.com' and '.example.com'.
This has resulted in a slight refactoring of config_register_addressmaps.
2. Add some more detail to the man page entry for AddressMap.
3. Fix initialization of a pointer to NULL rather than 0.
4. Update the unit tests to cater for the changes in 1 and test more explicitly for
recursive mapping.

1. Implement the following mapping rules:
MapAddress a.b.c d.e.f # This is what we have now
MapAddress .a.b.c d.e.f # Replaces any address ending with .a.b.c with d.e.f
MapAddress .a.b.c .d.e.f # Replaces the .a.b.c at the end of any addr with .d.e.f
(Note that 'a.b.c .d.e.f' is invalid, and will be rejected.)
2. Add tests for the new rules.
3. Allow proper wildcard annotation, i.e. '*.d.e' '.d.e' will still work.
4. Update addressmap_entry_t with an is_wildcard member.
|
|
Allow MapAddress to handle directives such as:
MapAddress .torproject.org .torserver.exit
MapAddress .org 1.1.1.1
Add tests for addressmap_rewrite.

Rename to *_orport for consistency with node_*.
|
|
This keeps the IP address and TCP for a given OR port together,
reducing the risk of using an address for one address family with a
port of another.
Make node_get_addr() a wrapper function for compatibility.
|
|
|
|
This is not as conservative as we could do it, f.ex. by looking at the
connection and only do this for connections to bridges. A non-bridge
should never have anything else than its primary IPv4 address set
though, so I think this is safe.

ipv6_preferred.
Don't touch the string representation in routerinfo_t->address.
Also, set or clear the routerinfo_t->ipv6_preferred flag based on the
address family of the bridge.
|
|
This should be safe to do for all uses of get_configured_bridge_by_routerinfo().
|
|
|
|
Comments below focus on changes, see diff for added code.
New type tor_addr_port_t holding an IP address and a TCP/UDP port.
New flag in routerinfo_t, ipv6_preferred. This should go in the
node_t instead but not now.
Replace node_get_addr() with
- node_get_prim_addr() for primary address, i.e. IPv4 for now
- node_get_pref_addr() for preferred address, IPv4 or IPv6.
Rename node_get_addr_ipv4h() node_get_prim_addr_ipv4h() for
consistency. The primary address will not allways be an IPv4 address.
Same for node_get_orport() -> node_get_prim_orport().
Rewrite node_is_a_configured_bridge() to take all OR ports into account.
Extend argument list to extend_info_from_node and
extend_info_from_router with a flag indicating if we want to use the
routers primary address or the preferred address. Use the preferred
address in as few situtations as possible for allowing clients to
connect to bridges over IPv6.
