+Subject: [PATCH] transport: add a protocol-whitelist environment variable
+
+If we are cloning an untrusted remote repository into a
+sandbox, we may also want to fetch remote submodules in
+order to get the complete view as intended by the other
+side. However, that opens us up to attacks where a malicious
+user gets us to clone something they would not otherwise
+have access to (this is not necessarily a problem by itself,
+but we may then act on the cloned contents in a way that
+exposes them to the attacker).
+
+Ideally such a setup would sandbox git entirely away from
+high-value items, but this is not always practical or easy
+to set up (e.g., OS network controls may block multiple
+protocols, and we would want to enable some but not others).
+
+We can help this case by providing a way to restrict
+particular protocols. We use a whitelist in the environment.
+This is more annoying to set up than a blacklist, but
+defaults to safety if the set of protocols git supports
+grows). If no whitelist is specified, we continue to default
+to allowing all protocols (this is an "unsafe" default, but
+since the minority of users will want this sandboxing
+effect, it is the only sensible one).
+
+A note on the tests: ideally these would all be in a single
+test file, but the git-daemon and httpd test infrastructure
+is an all-or-nothing proposition rather than a test-by-test
+prerequisite. By putting them all together, we would be
+unable to test the file-local code on machines without
+apache.

++`GIT_ALLOW_PROTOCOL`::
++	If set, provide a colon-separated list of protocols which are
++	allowed to be used with fetch/push/clone. This is useful to
++	restrict recursive submodule initialization from an untrusted
++	repository. Any protocol not mentioned will be disallowed (i.e.,
++	this is a whitelist, not a blacklist). If the variable is not
++	set at all, all protocols are enabled.  The protocol names
++	currently used by git are:
++
++	  - `file`: any local file-based path (including `file://` URLs,
++	    or local paths)
++
++	  - `git`: the anonymous git protocol over a direct TCP
++	    connection (or proxy, if configured)
++
++	  - `ssh`: git over ssh (including `host:path` syntax,
++	    `git+ssh://`, etc).
++
++	  - `rsync`: git over rsync
++
++	  - `http`: git over http, both "smart http" and "dumb http".
++	    Note that this does _not_ include `https`; if you want both,
++	    you should specify both as `http:https`.
++
++	  - any external helpers are named by their protocol (e.g., use
++	    `hg` to allow the `git-remote-hg` helper)
+++
++Note that this controls only git's internal protocol selection.
++If libcurl is used (e.g., by the `http` transport), it may
++redirect to other protocols. There is not currently any way to
++restrict this.

+Subject: [PATCH] submodule: allow only certain protocols for submodule fetches
+
+Some protocols (like git-remote-ext) can execute arbitrary
+code found in the URL. The URLs that submodules use may come
+from arbitrary sources (e.g., .gitmodules files in a remote
+repository). Let's restrict submodules to fetching from a
+known-good subset of protocols.
+
+Note that we apply this restriction to all submodule
+commands, whether the URL comes from .gitmodules or not.
+This is more restrictive than we need to be; for example, in
+the tests we run:
+
+  git submodule add ext::...
+
+which should be trusted, as the URL comes directly from the
+command line provided by the user. But doing it this way is
+simpler, and makes it much less likely that we would miss a
+case. And since such protocols should be an exception
+(especially because nobody who clones from them will be able
+to update the submodules!), it's not likely to inconvenience
+anyone in practice.

+Subject: [PATCH] transport: refactor protocol whitelist code
+
+The current callers only want to die when their transport is
+prohibited. But future callers want to query the mechanism
+without dying.
+
+Let's break out a few query functions, and also save the
+results in a static list so we don't have to re-parse for
+each query.

+Subject: [PATCH] http: limit redirection to protocol-whitelist
+
+Previously, libcurl would follow redirection to any protocol
+it was compiled for support with. This is desirable to allow
+redirection from HTTP to HTTPS. However, it would even
+successfully allow redirection from HTTP to SFTP, a protocol
+that git does not otherwise support at all. Furthermore
+git's new protocol-whitelisting could be bypassed by
+following a redirect within the remote helper, as it was
+only enforced at transport selection time.
+
+This patch limits redirects within libcurl to HTTP, HTTPS,
+FTP and FTPS. If there is a protocol-whitelist present, this
+list is limited to those also allowed by the whitelist. As
+redirection happens from within libcurl, it is impossible
+for an HTTP redirect to a protocol implemented within
+another remote helper.
+
+When the curl version git was compiled with is too old to
+support restrictions on protocol redirection, we warn the
+user if GIT_ALLOW_PROTOCOL restrictions were requested. This
+is a little inaccurate, as even without that variable in the
+environment, we would still restrict SFTP, etc, and we do
+not warn in that case. But anything else means we would
+literally warn every time git accesses an http remote.
+
+This commit includes a test, but it is not as robust as we
+would hope. It redirects an http request to ftp, and checks
+that curl complained about the protocol, which means that we
+are relying on curl's specific error message to know what
+happened. Ideally we would redirect to a working ftp server
+and confirm that we can clone without protocol restrictions,
+and not with them. But we do not have a portable way of
+providing an ftp server, nor any other protocol that curl
+supports (https is the closest, but we would have to deal
+with certificates).
+
+[jk: added test and version warning]

+Subject: [PATCH] http: limit redirection depth
+
+By default, libcurl will follow circular http redirects
+forever. Let's put a cap on this so that somebody who can
+trigger an automated fetch of an arbitrary repository (e.g.,
+for CI) cannot convince git to loop infinitely.
+
+The value chosen is 20, which is the same default that
+Firefox uses.
