2018-09-27fsck: detect submodule paths starting with dashJeff King
As with urls, submodule paths with dashes are ignored by git, but may end up confusing older versions. Detecting them via fsck lets us prevent modern versions of git from being a vector to spread broken .gitmodules to older versions. Compared to blocking leading-dash urls, though, this detection may be less of a good idea: 1. While such paths provide confusing and broken results, they don't seem to actually work as option injections against anything except "cd". In particular, the submodule code seems to canonicalize to an absolute path before running "git clone" (so it passes /your/clone/-sub). 2. It's more likely that we may one day make such names actually work correctly. Even after we revert this fsck check, it will continue to be a hassle until hosting servers are all updated. On the other hand, it's not entirely clear that the behavior in older versions is safe. And if we do want to eventually allow this, we may end up doing so with a special syntax anyway (e.g., writing "./-sub" in the .gitmodules file, and teaching the submodule code to canonicalize it when comparing). So on balance, this is probably a good protection. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Urls with leading dashes can cause mischief on older versions of Git. We should detect them so that they can be rejected by receive.fsckObjects, preventing modern versions of git from being a vector by which attacks can spread.

2018-09-27submodule-config: ban submodule paths that start with a dashJeff King
We recently banned submodule urls that look like command-line options. This is the matching change to ban leading-dash paths. As with the urls, this should not break any use cases that currently work. Even with our "--" separator passed to git-clone, git-submodule.sh gets confused. Without the code portion of this patch, the clone of "-sub" added in t7417 would yield results like: /path/to/git-submodule: 410: cd: Illegal option -s /path/to/git-submodule: 417: cd: Illegal option -s /path/to/git-submodule: 410: cd: Illegal option -s /path/to/git-submodule: 417: cd: Illegal option -s Fetched in submodule path '-sub', but it did not contain b56243f8f4eb91b2f1f8109452e659f14dd3fbe4. Direct fetching of that commit failed. Moreover, naively adding such a submodule doesn't work: $ git submodule add $url -sub The following path is ignored by one of your .gitignore files: -sub even though there is no such ignore pattern (the test script hacks around this with a well-placed "git mv"). Unlike leading-dash urls, though, it's possible that such a path _could_ be useful if we eventually made it work. So this commit should be seen not as recommending a particular policy, but rather temporarily closing off a broken and possibly dangerous code-path. We may revisit this decision later. There are two minor differences to the tests in t7416 (that covered urls): 1. We don't have a "./-sub" escape hatch to make this work, since the submodule code expects to be able to match canonical index names to the path field (so you are free to add submodule config with that path, but we would never actually use it, since an index entry would never start with "./"). 2. After this patch, cloning actually succeeds. Since we ignore the submodule.*.path value, we fail to find a config stanza for our submodule at all, and simply treat it as inactive. We still check for the "ignoring" message. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-09-27submodule-config: ban submodule urls that start with dashJeff King
The previous commit taught the submodule code to invoke our "git clone $url $path" with a "--" separator so that we aren't confused by urls or paths that start with dashes. However, that's just one code path. It's not clear if there are others, and it would be an easy mistake to add one in the future. Moreover, even with the fix in the previous commit, it's quite hard to actually do anything useful with such an entry. Any url starting with a dash must fall into one of three categories: - it's meant as a file url, like "-path". But then any clone is not going to have the matching path, since it's by definition relative inside the newly created clone. If you spell it as "./-path", the submodule code sees the "/" and translates this to an absolute path, so it at least works (assuming the receiver has the same filesystem layout as you). But that trick does not apply for a bare "-path". - it's meant as an ssh url, like "-host:path". But this already doesn't work, as we explicitly disallow ssh hostnames that begin with a dash (to avoid option injection against ssh). - it's a remote-helper scheme, like "-scheme::data". This _could_ work if the receiver bends over backwards and creates a funny-named helper like "git-remote--scheme". But normally there would not be any helper that matches. Since such a url does not work today and is not likely to do anything useful in the future, let's simply disallow them entirely. That protects the existing "git clone" path (in a belt-and-suspenders way), along with any others that might exist. Our tests cover two cases: 1. A file url with "./" continues to work, showing that there's an escape hatch for people with truly silly repo names. 2. A url starting with "-" is rejected. Note that we expect case (2) to fail, but it would have done so even without this commit, for the reasons given above. So instead of just expecting failure, let's also check for the magic word "ignoring" on stderr. That lets us know that we failed for the right reason.

2018-09-27submodule--helper: use "--" to signal end of clone optionsJeff King
When we clone a submodule, we call "git clone $url $path". But there's nothing to say that those components can't begin with a dash themselves, confusing git-clone into thinking they're options. Let's pass "--" to make it clear what we expect. There's no test here, because it's actually quite hard to make these names work, even with "git clone" parsing them correctly. And we're going to restrict these cases even further in future commits. So we'll leave off testing until then; this is just the minimal fix to prevent us from doing something stupid with a badly formed entry.

2018-06-18ewah: adjust callers of ewah_read_mmap()Jeff King
The return value of ewah_read_mmap() is now an ssize_t, since we could (in theory) process up to 32GB of data. This would never happen in practice, but a corrupt or malicious .bitmap or index file could convince us to do so. Let's make sure that we don't stuff the value into an int, which would cause us to incorrectly move our pointer forward. We'd always move too little, since negative values are used for reporting errors. So the worst case is just that we end up reporting a corrupt file, not an out-of-bounds read.

2018-06-18ewah_read_mmap: bounds-check mmap readsJeff King
The on-disk ewah format tells us how big the ewah data is, and we blindly read that much from the buffer without considering whether the mmap'd data is long enough, which can lead to out-of-bound reads. Let's make sure we have data available before reading it, both for the ewah header/footer as well as for the bit data itself. In particular: - keep our ptr/len pair in sync as we move through the buffer, and check it before each read - check the size for integer overflow (this should be impossible on 64-bit, as the size is given as a 32-bit count of 8-byte words, but is possible on a 32-bit system) - return the number of bytes read as an ssize_t instead of an int, again to prevent integer overflow - compute the return value using a pointer difference; this should yield the same result as the existing code, but makes it more obvious that we got our computations right The included test is far from comprehensive, as it just picks a static point at which to truncate the generated bitmap. But in practice this will hit in the middle of an ewah and make sure we're at least exercising this code.

2018-06-18t3200: clarify description of --set-upstream testKaartic Sivaraam
Support for the --set-upstream option was removed in 52668846ea (builtin/branch: stop supporting the "--set-upstream" option, 2017-08-17). The change did not completely remove the command due to an issue noted in the commit's log message. So, a test was added to ensure that a command which uses the '--set-upstream' option fails instead of silently acting as an alias for the '--set-upstream-to' option due to option parsing features. To avoid confusion, clarify that the option is disabled intentionally in the corresponding test description. The test is expected to be around as long as we intentionally fail on seeing the '--set-upstream' option which in turn we expect to do for a period of time after which we can be sure that existing users of '--set-upstream' are aware that the option is no longer supported.
