2018-05-21index-pack: check .gitmodules files with --strictLibravatar Jeff King1-0/+10
Now that the internal fsck code has all of the plumbing we need, we can start checking incoming .gitmodules files. Naively, it seems like we would just need to add a call to fsck_finish() after we've processed all of the objects. And that would be enough to cover the initial test included here. But there are two extra bits: 1. We currently don't bother calling fsck_object() at all for blobs, since it has traditionally been a noop. We'd actually catch these blobs in fsck_finish() at the end, but it's more efficient to check them when we already have the object loaded in memory. 2. The second pass done by fsck_finish() needs to access the objects, but we're actually indexing the pack in this process. In theory we could give the fsck code a special callback for accessing the in-pack data, but it's actually quite tricky: a. We don't have an internal efficient index mapping oids to packfile offsets. We only generate it on the fly as part of writing out the .idx file. b. We'd still have to reconstruct deltas, which means we'd basically have to replicate all of the reading logic in packfile.c. Instead, let's avoid running fsck_finish() until after we've written out the .idx file, and then just add it to our internal packed_git list. This does mean that the objects are "in the repository" before we finish our fsck checks. But unpack-objects already exhibits this same behavior, and it's an acceptable tradeoff here for the same reason: the quarantine mechanism means that pushes will be fully protected. In addition to a basic push test in t7415, we add a sneaky pack that reverses the usual object order in the pack, requiring that index-pack access the tree and blob during the "finish" step. This already works for unpack-objects (since it will have written out loose objects), but we'll check it with this sneaky pack for good measure. Signed-off-by: Jeff King <peff@peff.net>
2018-05-21unpack-objects: call fsck_finish() after fscking objectsLibravatar Jeff King1-1/+4
As with the previous commit, we must call fsck's "finish" function in order to catch any queued objects for .gitmodules checks. This second pass will be able to access any incoming objects, because we will have exploded them to loose objects by now. This isn't quite ideal, because it means that bad objects may have been written to the object database (and a subsequent operation could then reference them, even if the other side doesn't send the objects again). However, this is sufficient when used with receive.fsckObjects, since those loose objects will all be placed in a temporary quarantine area that will get wiped if we find any problems. Signed-off-by: Jeff King <peff@peff.net>
2018-05-21fsck: call fsck_finish() after fscking objectsLibravatar Jeff King1-0/+3
Now that the internal fsck code is capable of checking .gitmodules files, we just need to teach its callers to use the "finish" function to check any queued objects. With this, we can now catch the malicious case in t7415 with git-fsck. Signed-off-by: Jeff King <peff@peff.net>
2018-05-21fsck: actually fsck blob dataLibravatar Jeff King1-22/+20
Because fscking a blob has always been a noop, we didn't bother passing around the blob data. In preparation for content-level checks, let's fix up a few things: 1. The fsck_object() function just returns success for any blob. Let's a noop fsck_blob(), which we can fill in with actual logic later. 2. The fsck_loose() function in builtin/fsck.c just threw away blob content after loading it. Let's hold onto it until after we've called fsck_object(). The easiest way to do this is to just drop the parse_loose_object() helper entirely. Incidentally, this also fixes a memory leak: if we successfully loaded the object data but did not parse it, we would have left the function without freeing it. 3. When fsck_loose() loads the object data, it does so with a custom read_loose_object() helper. This function streams any blobs, regardless of size, under the assumption that we're only checking the sha1. Instead, let's actually load blobs smaller than big_file_threshold, as the normal object-reading code-paths would do. This lets us fsck small files, and a NULL return is an indication that the blob was so big that it needed to be streamed, and we can pass that information along to fsck_blob(). Signed-off-by: Jeff King <peff@peff.net>
2018-05-21index-pack: make fsck error message more specificLibravatar Jeff King2-2/+2
If fsck reports an error, we say only "Error in object". This isn't quite as bad as it might seem, since the fsck code would have dumped some errors to stderr already. But it might help to give a little more context. The earlier output would not have even mentioned "fsck", and that may be a clue that the "fsck.*" or "*.fsckObjects" config may be relevant.

It should be OK to pass "0" here, since we're just manipulating the untracked cache, not an actual index entry. - the lstat() in builtin/update-index.c:update_one() needs to be updated to handle the fsmonitor case (without this it still behaves correctly, but does an unnecessary lstat).
2018-05-21verify_path: disallow symlinks in .gitmodulesLibravatar Jeff King1-3/+3
There are a few reasons it's not a good idea to make .gitmodules a symlink, including: 1. It won't be portable to systems without symlinks. 2. It may behave inconsistently, since Git may look at this file in the index or a tree without bothering to resolve any symbolic links. We don't do this _yet_, but the config infrastructure is there and it's planned for the future. With some clever code, we could make (2) work. And some people may not care about (1) if they only work on one platform. But there are a few security reasons to simply disallow it: a. A symlinked .gitmodules file may circumvent any fsck checks of the content. b. Git may read and write from the on-disk file without sanity checking the symlink target. So for example, if you link ".gitmodules" to "../oops" and run "git submodule add", we'll write to the file "oops" outside the repository. Again, both of those are problems that _could_ be solved with sufficient code, but given the complications in (1) and (2), we're better off just outlawing it explicitly. Note the slightly tricky call to verify_path() in update-index's update_one(). There we may not have a mode if we're not updating from the filesystem (e.g., we might just be removing the file). Passing "0" as the mode there works fine; since it's not a symlink, we'll just skip the extra checks. Signed-off-by: Jeff King <peff@peff.net>
2018-05-21update-index: stat updated files earlierLibravatar Jeff King1-8/+17
In the update_one(), we check verify_path() on the proposed path before doing anything else. In preparation for having verify_path() look at the file mode, let's stat the file earlier, so we can check the mode accurately. This is made a bit trickier by the fact that this function only does an lstat in a few code paths (the ones that flow down through process_path()). So we can speculatively do the lstat() here and pass the results down, and just use a dummy mode for cases where we won't actually be updating the index from the filesystem. Signed-off-by: Jeff King <peff@peff.net>
2018-05-21submodule-config: verify submodule names as pathsLibravatar Jeff King1-0/+24
Submodule "names" come from the untrusted .gitmodules file, but we blindly append them to $GIT_DIR/modules to create our on-disk repo paths. This means you can do bad things by putting "../" into the name (among other things). Let's sanity-check these names to avoid building a path that can be exploited. There are two main decisions: 1. What should the allowed syntax be? It's tempting to reuse verify_path(), since submodule names typically come from in-repo paths. But there are two reasons not to: a. It's technically more strict than what we need, as we really care only about breaking out of the $GIT_DIR/modules/ hierarchy. E.g., having a submodule named "foo/.git" isn't actually dangerous, and it's possible that somebody has manually given such a funny name. b. Since we'll eventually use this checking logic in fsck to prevent downstream repositories, it should be consistent across platforms. Because verify_path() relies on is_dir_sep(), it wouldn't block "foo\..\bar" on a non-Windows machine. 2. Where should we enforce it? These days most of the .gitmodules reads go through submodule-config.c, so I've put it there in the reading step. That should cover all of the C code. We also construct the name for "git submodule add" inside the git-submodule.sh script. This is probably not a big deal for security since the name is coming from the user anyway, but it would be polite to remind them if the name they pick is invalid (and we need to expose the name-checker to the shell anyway for our test scripts). This patch issues a warning when reading .gitmodules and just ignores the related config entry completely. This will generally end up producing a sensible error, as it works the same as a .gitmodules file which is missing a submodule entry (so "submodule update" will barf, but "git clone --recurse-submodules" will print an error but not abort the clone. There is one minor oddity, which is that we print the warning once per malformed config key (since that's how the config subsystem gives us the entries). So in the new test, for example, the user would see three warnings. That's OK, since the intent is that this case should never come up outside of malicious repositories (and then it might even benefit the user to see the message multiple times). Credit for finding this vulnerability and the proof of concept from which the test script was adapted goes to Etienne Stalmans. Signed-off-by: Jeff King <peff@peff.net>

2018-05-21config: die when --blob is used outside a repositoryLibravatar Jeff King1-0/+3
If you run "config --blob" outside of a repository, then we eventually try to resolve the blob name and hit a BUG(). Let's catch this earlier and provide a useful message. Note that we could also catch this much lower in the stack, in git_config_from_blob_ref(). That might cover other callsites, too, but it's unclear whether those ones would actually be bugs or not. So let's leave the low-level functions to assume the caller knows what it's doing (and BUG() if it turns out it doesn't).
