| * signed push: allow stale nonce in stateless modeJunio C Hamano2014-09-174-12/+112
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When operating with the stateless RPC mode, we will receive a nonce issued by another instance of us that advertised our capability and refs some time ago. Update the logic to check received nonce to detect this case, compute how much time has passed since the nonce was issued and report the status with a new environment variable GIT_PUSH_CERT_NONCE_SLOP to the hooks. GIT_PUSH_CERT_NONCE_STATUS will report "SLOP" in such a case. The hooks are free to decide how large a slop it is willing to accept. Strictly speaking, the "nonce" is not really a "nonce" anymore in the stateless RPC mode, as it will happily take any "nonce" issued by it (which is protected by HMAC and its secret key) as long as it is fresh enough. The degree of this security degradation, relative to the native protocol, is about the same as the "we make sure that the 'git push' decided to update our refs with new objects based on the freshest observation of our refs by making sure the values they claim the original value of the refs they ask us to update exactly match the current state" security is loosened to accomodate the stateless RPC mode in the existing code without this series, so there is no need for those who are already using smart HTTP to push to their repositories to be alarmed any more than they already are. In addition, the server operator can set receive.certnonceslop configuration variable to specify how stale a nonce can be (in seconds). When this variable is set, and if the nonce received in the certificate that passes the HMAC check was less than that many seconds old, hooks are given "OK" in GIT_PUSH_CERT_NONCE_STATUS (instead of "SLOP") and the received nonce value is given in GIT_PUSH_CERT_NONCE, which makes it easier for a simple-minded hook to check if the certificate we received is recent enough.

| * signed push: teach smart-HTTP to pass "git push --signed" aroundJunio C Hamano2014-09-176-3/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "--signed" option received by "git push" is first passed to the transport layer, which the native transport directly uses to notice that a push certificate needs to be sent. When the transport-helper is involved, however, the option needs to be told to the helper with set_helper_option(), and the helper needs to take necessary action. For the smart-HTTP helper, the "necessary action" involves spawning the "git send-pack" subprocess with the "--signed" option. Once the above all gets wired in, the smart-HTTP transport now can use the push certificate mechanism to authenticate its pushes. Add a test that is modeled after tests for the native transport in t5534-push-signed.sh to t5541-http-push-smart.sh. Update the test Apache configuration to pass GNUPGHOME environment variable through. As PassEnv would trigger warnings for an environment variable that is not set, export it from test-lib.sh set to a harmless value when GnuPG is not being used in the tests. Note that the added test is deliberately loose and does not check the nonce in this step. This is because the stateless RPC mode is inevitably flaky and a nonce that comes back in the actual push processing is one issued by a different process; if the two interactions with the server crossed a second boundary, the nonces will not match and such a check will fail. A later patch in the series will work around this shortcoming. Signed-off-by: Junio C Hamano <gitster@pobox.com>
| * signed push: fortify against replay attacksJunio C Hamano2014-09-177-29/+187
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to prevent a valid push certificate for pushing into an repository from getting replayed in a different push operation, send a nonce string from the receive-pack process and have the signer include it in the push certificate. The receiving end uses an HMAC hash of the path to the repository it serves and the current time stamp, hashed with a secret seed (the secret seed does not have to be per-repository but can be defined in /etc/gitconfig) to generate the nonce, in order to ensure that a random third party cannot forge a nonce that looks like it originated from it. The original nonce is exported as GIT_PUSH_CERT_NONCE for the hooks to examine and match against the value on the "nonce" header in the certificate to notice a replay, but returned "nonce" header in the push certificate is examined by receive-pack and the result is exported as GIT_PUSH_CERT_NONCE_STATUS, whose value would be "OK" if the nonce recorded in the certificate matches what we expect, so that the hooks can more easily check.

| * signed push: add "pushee" header to push certificateJunio C Hamano2014-09-154-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Record the URL of the intended recipient for a push (after anonymizing it if it has authentication material) on a new "pushee URL" header. Because the networking configuration (SSH-tunnels, proxies, etc.) on the pushing user's side varies, the receiving repository may not know the single canonical URL all the pushing users would refer it as (besides, many sites allow pushing over ssh://host/path and https://host/path protocols to the same repository but with different local part of the path). So this value may not be reliably used for replay-attack prevention purposes, but this will still serve as a human readable hint to identify the repository the certificate refers to.

| * signed push: remove duplicated protocol infoJunio C Hamano2014-09-154-4/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the interim protocol, we used to send the update commands even though we already send a signed copy of the same information when push certificate is in use. Update the send-pack/receive-pack pair not to do so. The notable thing on the receive-pack side is that it makes sure that there is no command sent over the traditional protocol packet outside the push certificate. Otherwise a pusher can claim to be pushing one set of ref updates in the signed certificate while issuing commands to update unrelated refs, and such an update will evade later audits. Finally, start documenting the protocol. Signed-off-by: Junio C Hamano <gitster@pobox.com>
| * send-pack: send feature request on push-cert packetJunio C Hamano2014-09-152-5/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We would want to update the interim protocol so that we do not send the usual update commands when the push certificate feature is in use, as the same information is in the certificate. Once that happens, the push-cert packet may become the only protocol command, but then there is no packet to put the feature request behind, like we always did. As we have prepared the receiving end that understands the push-cert feature to accept the feature request on the first protocol packet (other than "shallow ", which was an unfortunate historical mistake that has to come before everything else), we can give the feature request on the push-cert packet instead of the first update protocol packet, in preparation for the next step to actually update to the final protocol.

| * push: the beginning of "git push --signed"Junio C Hamano2014-09-1510-2/+253
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While signed tags and commits assert that the objects thusly signed came from you, who signed these objects, there is not a good way to assert that you wanted to have a particular object at the tip of a particular branch. My signing v2.0.1 tag only means I want to call the version v2.0.1, and it does not mean I want to push it out to my 'master' branch---it is likely that I only want it in 'maint', so the signature on the object alone is insufficient. The only assurance to you that 'maint' points at what I wanted to place there comes from your trust on the hosting site and my authentication with it, which cannot easily audited later. Introduce a mechanism that allows you to sign a "push certificate" (for the lack of better name) every time you push, asserting that what object you are pushing to update which ref that used to point at what other object. Think of it as a cryptographic protection for ref updates, similar to signed tags/commits but working on an orthogonal axis. The basic flow based on this mechanism goes like this: 1. You push out your work with "git push --signed". 2. The sending side learns where the remote refs are as usual, together with what protocol extension the receiving end supports. If the receiving end does not advertise the protocol extension "push-cert", an attempt to "git push --signed" fails. Otherwise, a text file, that looks like the following, is prepared in core: certificate version 0.1 pusher Junio C Hamano <gitster@pobox.com> 1315427886 -0700 7339ca65... 21580ecb... refs/heads/master 3793ac56... 12850bec... refs/heads/next The file begins with a few header lines, which may grow as we gain more experience. The 'pusher' header records the name of the signer (the value of user.signingkey configuration variable, falling back to GIT_COMMITTER_{NAME|EMAIL}) and the time of the certificate generation. After the header, a blank line follows, followed by a copy of the protocol message lines. Each line shows the old and the new object name at the tip of the ref this push tries to update, in the way identical to how the underlying "git push" protocol exchange tells the ref updates to the receiving end (by recording the "old" object name, the push certificate also protects against replaying). It is expected that new command packet types other than the old-new-refname kind will be included in push certificate in the same way as would appear in the plain vanilla command packets in unsigned pushes. The user then is asked to sign this push certificate using GPG, formatted in a way similar to how signed tag objects are signed, and the result is sent to the other side (i.e. receive-pack). In the protocol exchange, this step comes immediately before the sender tells what the result of the push should be, which in turn comes before it sends the pack data. 3. When the receiving end sees a push certificate, the certificate is written out as a blob. The pre-receive hook can learn about the certificate by checking GIT_PUSH_CERT environment variable, which, if present, tells the object name of this blob, and make the decision to allow or reject this push. Additionally, the post-receive hook can also look at the certificate, which may be a good place to log all the received certificates for later audits. Because a push certificate carry the same information as the usual command packets in the protocol exchange, we can omit the latter when a push certificate is in use and reduce the protocol overhead. This however is not included in this patch to make it easier to review (in other words, the series at this step should never be released without the remainder of the series, as it implements an interim protocol that will be incompatible with the final one). As such, the documentation update for the protocol is left out of this step. Signed-off-by: Junio C Hamano <gitster@pobox.com>

| * gpg-interface: move parse_signature() to where it should beJunio C Hamano2014-09-154-21/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our signed-tag objects set the standard format used by Git to store GPG-signed payload (i.e. the payload followed by its detached signature) [*1*], and it made sense to have a helper to find the boundary between the payload and its signature in tag.c back then. Newer code added later to parse other kinds of objects that learned to use the same format to store GPG-signed payload (e.g. signed commits), however, kept using the helper from the same location. Move it to gpg-interface; the helper is no longer about signed tag, but it is how our code and data interact with GPG.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earlier, ffb6d7d5 (Move commit GPG signature verification to commit.c, 2013-03-31) moved this helper that used to be in pretty.c (i.e. the output code path) to commit.c for better reusability. It was a good first step in the right direction, but still suffers from a myopic view that commits will be the only thing we would ever want to sign---we would actually want to be able to reuse it even wider. The function interprets what GPG said; gpg-interface is obviously a better place. Move it there. Signed-off-by: Junio C Hamano <gitster@pobox.com>
| * send-pack: clarify that cmds_sent is a booleanJunio C Hamano2014-09-151-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We use it to make sure that the feature request is sent only once on the very first request packet (ignoring the "shallow " line, which was an unfortunate mistake we cannot retroactively fix with existing receive-pack already deployed in the field) and we set it to "true" with cmds_sent++, not because we care about the actual number of updates sent but because it is merely an idiomatic way. Set it explicitly to one to clarify that the code that uses this variable only cares about its zero-ness. Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main loop over remote_refs list inspects the ref status to see if we need to generate pack data (i.e. a delete-only push does not need to send any additional data), resets it to "expecting the status report" state, and formats the actual update commands to be sent. Split the former two out of the main loop, as it will become conditional in later steps. Besides, we should have code that does real thing here, before the "Finally, tell the other end!" part ;-) Signed-off-by: Junio C Hamano <gitster@pobox.com>

| * send-pack: move REF_STATUS_REJECT_NODELETE logic a bit higherJunio C Hamano2014-09-151-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 20e8b465 (refactor ref status logic for pushing, 2010-01-08) restructured the code to set status for each ref to be pushed, but did not quite go far enough. We inspect the status set earlier by set_refs_status_for_push() and then perform yet another update to the status of a ref with an otherwise OK status to be deleted to mark it with REF_STATUS_REJECT_NODELETE when the protocol tells us never to delete. Split the latter into a separate loop that comes before we enter the per-ref loop. This way we would have one less condition to check in the main loop.

This code wasn't used in any default circumstances, as the build system never sets NO_STRUCT_ITIMERVAL - this breakage only occured if the user asked for it. We repair this case so we can rely on it in the following commits. Signed-off-by: Jonas 'Sortie' Termansen <sortie@maxsi.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The same for GIT_PATCHID_TIMING_TESTS in t3419. While this may have seemed a good flexibility, in reality if you are concentrating on a single test (e.g. t3302), you can just run that single test with the GIT_TEST_LONG to trigger expensive tests. It does not seem worth forcing other people who may want to come up with their own expensive tests to invent new environment variables by keeping this convention. Drop them.

Introduced in 331a1838b (2010-07-02, Try normalizing files to avoid delete/modify conflicts when merging), which is quite a long time ago, so I'm rather unsure if it's of any impact or just went unnoticed. The line after the changed line has a comparison of 'o.len' to 'a.len', so we should assume the lengths may be different. I'd be happy to have a test for this bug(?) attached to t6031-merge-recursive.sh, but I did not manage to come up with a test in a reasonable amount of time.
