Without this check, we potentially look up to 3 characters before
the start of a malloc'd segment, which could provoke a crash under
certain (weird afaik) circumstances.
Fixes 17404; bugfix on 0.2.6.3-alpha.
* Don't assume that every test box has an IPv4 address
* Don't assume that every test box has a non-local address
Resolves issue #17255 released in unit tests in 0.2.7.3-rc.
Now that x509_get_not{Before,After} are functions in OpenSSL 1.1
(not yet releasesd), we need to define a variant that takes a const
pointer to X509 and returns a const pointer to ASN1_time.
Part of 17237. I'm not convinced this is an openssl bug or a tor
bug. It might be just one of those things.
Ensure that either a valid address is returned in address pointers,
or that the address data is zeroed on error.
Ensure that free_interface_address6_list handles NULL lists.
Add unit tests for get_interface_address* failure cases.
Fixes bug #17173.
Patch by fk/teor, not in any released version of tor.
Use environment variables instead. This repairs 'make distcheck',
which was running into trouble when it tried to chmod the generated
scripts.
Fixes 17148.
This allows builds on machines with a crippled openssl to fail early
during configure. Bugfix on 0.2.7.1-alpha, which introduced the
requirement for ECC support. Fixes bug 17109.
Advise users how to configure separate IPv4 and IPv6 exit
policies in the manpage and sample torrcs.
Related to fixes in ticket #16069 and #17027. Patch by "teor".
Patch on 2eb7eafc9d and a96c0affcb (25 Oct 2012),
released in 0.2.4.7-alpha.
src/test/test_policy.c:
Merged calls to policies_parse_exit_policy by adding additional arguments.
fixup to remaining instance of ~EXIT_POLICY_IPV6_ENABLED.
Compacting logic test now produces previous list length of 4, corrected this.
src/config/torrc.sample.in:
src/config/torrc.minimal.in-staging:
Merged torrc modification dates in favour of latest.
ExitPolicyRejectPrivate now rejects more local addresses by default:
* the relay's published IPv6 address (if any), and
* any publicly routable IPv4 or IPv6 addresses on any local interfaces.
This resolves a security issue for IPv6 Exits and multihomed Exits that
trust connections originating from localhost.
Resolves ticket 17027. Patch by "teor".
Patch on 42b8fb5a15 (11 Nov 2007), released in 0.2.0.11-alpha.
In previous versions of Tor, ExitPolicy accept6/reject6 * produced
policy entries for IPv4 and IPv6 wildcard addresses.
To reduce operator confusion, change accept6/reject6 * to only produce
an IPv6 wildcard address.
Resolves bug #16069.
Patch on 2eb7eafc9d and a96c0affcb (25 Oct 2012),
released in 0.2.4.7-alpha.
Tor now warns when ExitPolicy lines occur after accept/reject *:*
or variants. These lines are redundant, and were always ignored.
Partial fix for ticket 16069. Patch by "teor".
Patch on 2eb7eafc9d and a96c0affcb (25 Oct 2012),
released in 0.2.4.7-alpha.
When parsing torrc ExitPolicies, we now warn if:
* an IPv4 address is used on an accept6 or reject6 line. The line is
ignored, but the rest of the policy items in the list are used.
(accept/reject continue to allow both IPv4 and IPv6 addresses in torrcs.)
* a "private" address alias is used on an accept6 or reject6 line.
The line filters both IPv4 and IPv6 private addresses, disregarding
the 6 in accept6/reject6.
When parsing torrc ExitPolicies, we now issue an info-level message:
* when expanding an accept/reject * line to include both IPv4 and IPv6
wildcard addresses.
In each instance, usage advice is provided to avoid the message.
Partial fix for ticket 16069. Patch by "teor".
Patch on 2eb7eafc9d and a96c0affcb (25 Oct 2012),
released in 0.2.4.7-alpha.
Add get_interface_address[6]_list by refactoring
get_interface_address6. Add unit tests for new and existing functions.
Preparation for ticket 17027. Patch by "teor".
Patch on 42b8fb5a15 (11 Nov 2007), released in 0.2.0.11-alpha.
