* Use rel=nofollow microformat for dynamic (CGI-related) URLsSimon McVittie2017-01-09
| | | | | | | Some of these might be relatively expensive to dereference or result in messages being logged, and there's no reason why a search engine should need to index them. (In particular, we'd probably prefer search engines to index the rendered page, not its source code.)
* t/git-cgi.t: fix race conditionSimon McVittie2017-01-09
| | | | | We need the changes to take place at least 1 second after the first rebuild, so that the changed files are seen to have changed.

* | git: Do not disable commit hook for temporary working treeSimon McVittie2016-12-29
| | | | | | | | | | | | | | | | We exclude .git/hooks from symlinking into the temporary working tree, which avoids the commit hook being run for the temporary branch anyway. This avoids the wiki not being updated if an orthogonal change is received in process A, while process B prepares a revert that is subsequently cancelled.

* git: Do the revert operation in a secondary working treeSimon McVittie2016-12-28

| | | | | | This will be necessary when we use a secondary working tree to do reverts without leaving the primary working tree in an inconsistent state.

* Try revert operations (on a branch) before approving themSimon McVittie2016-12-28
| | | | | | | | | | | | | | | | | Otherwise, we have a time-of-check/time-of-use vulnerability: rcs_preprevert previously looked at what changed in the commit we are reverting, not at what would result from reverting it now. In particular, if some files were renamed since the commit we are reverting, a revert of changes that were within the designated subdirectory and allowed by check_canchange() might now affect files that are outside the designated subdirectory or disallowed by check_canchange(). It is not sufficient to disable rename detection, since git older than 2.8.0rc0 (in particular the version in Debian stable) silently accepts and ignores the relevant options. OVE-20161226-0002
* Revert "Tell `git revert` not to follow renames"Simon McVittie2016-12-28
| | | | | | | This doesn't work prior to git 2.8: `git revert` silently ignores the option and succeeds. We will have to fix CVE-2016-10026 some other way. This reverts commit 9cada49ed6ad24556dbe9861ad5b0a9f526167f9.
* Force CGI::FormBuilder->field to scalar context where necessarySimon McVittie2016-12-28
| | | | | | | | | | | | | | | | | | | | | | | | | | CGI::FormBuilder->field has behaviour similar to the CGI.pm misfeature we avoided in f4ec7b0. Force it into scalar context where it is used in an argument list. This prevents two (relatively minor) commit metadata forgery vulnerabilities: * In the comments plugin, an attacker who was able to post a comment could give it a user-specified author and author-URL even if the wiki configuration did not allow for that, by crafting multiple values to other fields. * In the editpage plugin, an attacker who was able to edit a page could potentially forge commit authorship by crafting multiple values for the rcsinfo field. The remaining plugins changed in this commit appear to have been protected by use of explicit scalar prototypes for the called functions, but have been changed anyway to make them more obviously correct. In particular, checkpassword() in passwordauth has a known prototype, so an attacker cannot trick it into treating multiple values of the name field as being the username, password and field to check for.

* git: do not fail to commit if committer is anonymousSimon McVittie2016-12-28

* git: don't issue a warning if rcsinfo is undefinedSimon McVittie2016-12-28
| | | | | | The intention here seems to be that $prev may be undefined, and the only way that can legitimately happen is for $params{token} to be undefined too.
* git_revert test: reinstate ikiwiki.setup, and make it work uninstalledSimon McVittie2016-12-28
| | | | | | | | | | | | | | Previously it was relying on running with an installed ikiwiki and being able to copy in recentchanges.mdwn and wikiicons/ from the underlay in /usr. The underlay in ./underlays/basewiki can't be used (yet) because ikiwiki doesn't allow following symlinks, even from underlays. I'd like to make ikiwiki follow symlinks whose destinations can be verified to be safe (for example making it willing to expose /usr/share/javascript to the web, but not /etc/passwd), at least from underlays, but this is security-sensitive so I'm not going to rush into it.
