transports: http: fix custom headers not being applied
In commit b9c5b15a7 (http: use the new httpclient, 2019-12-22), the HTTP
code got refactored to extract a generic HTTP client that operates
independently of the Git protocol. Part of refactoring was the creation
of a new `git_http_request` struct that encapsulates the generation of
requests. Our Git-specific HTTP transport was converted to use that in
`generate_request`, but during the process we forgot to set up custom
headers for the `git_http_request` and as a result we do not send out
these headers anymore.
Fix the issue by correctly setting up the request's custom headers and
add a test to verify we correctly send them.

credential: change git_cred to git_credential
We avoid abbreviations where possible; rename git_cred to
git_credential.
In addition, we have standardized on a trailing `_t` for enum types,
instead of using "type" in the name. So `git_credtype_t` has become
`git_credential_t` and its members have become `GIT_CREDENTIAL` instead
of `GIT_CREDTYPE`.
Finally, the source and header files have been renamed to `credential`
instead of `cred`.
Keep previous name and values as deprecated, and include the new header
files from the previous ones.

http: send probe packets
When we're authenticating with a connection-based authentication scheme
(NTLM, Negotiate), we need to make sure that we're still connected
between the initial GET where we did the authentication and the POST
that we're about to send. Our keep-alive session may have not kept
alive, but more likely, some servers do not authenticate the entire
keep-alive connection and may have "forgotten" that we were
authenticated, namely Apache and nginx.
Send a "probe" packet, that is an HTTP POST request to the upload-pack
or receive-pack endpoint, that consists of an empty git pkt ("0000").
If we're authenticated, we'll get a 200 back. If we're not, we'll get a
401 back, and then we'll resend that probe packet with the first step of
our authentication (asking to start authentication with the given
scheme). We expect _yet another_ 401 back, with the authentication
challenge.
Finally, we will send our authentication response with the actual POST
data. This will allow us to authenticate without draining the POST data
in the initial request that gets us a 401.

httpclient: support expect/continue
Allow users to opt-in to expect/continue handling when sending a POST
and we're authenticated with a "connection-based" authentication
mechanism like NTLM or Negotiate.
If the response is a 100, return to the caller (to allow them to post
their body). If the response is *not* a 100, buffer the response for
the caller.
HTTP expect/continue is generally safe, but some legacy servers
have not implemented it correctly. Require it to be opt-in.

'Negotiate' supports default credentials).
Set up an authentication context for this mechanism and these
credentials. Continue exchanging challenge/responses until we're
authenticated.

httpclient: consume final chunk message
When sending a new request, ensure that we got the entirety of the
response body. Our caller may have decided that they were done reading.
If we were not at the end of the message, this means that we need to
tear down the connection and cannot do keep-alive.
However, if the caller read all of the message, but we still have a
final end-of-response chunk signifier (ie, "0\r\n\r\n") on the socket,
then we should consider that the response was successfully copmleted.
If we're asked to send a new request, try to read from the socket, just
to clear out that end-of-chunk message, marking ourselves as
disconnected on any errors.

httpclient: introduce a simple http implementation
Introduce a new http client implementation that can GET and POST to
remote URLs.
Consumers can use `git_http_client_init` to create a new client,
`git_http_client_send_request` to send a request to the remote server
and `git_http_client_read_response` to read the response.
The http client implementation will perform the I/O with the remote
server (http or https) but does not understand the git smart transfer
protocol. This allows us to split the concerns of the http subtransport
from the actual http implementation.

gssapi: protect GSS_ERROR macro
The GSS_ERROR(x) macro may expand to `(x & value)` on some
implementations, instead of `((x) & value)`. This is the case on macOS,
which means that if we attempt to wrap an expression in that macro, like
`a = b`, then that would expand to `(a = b & value)`.
Since `&` has a higher precedence, this is not at all what we want, and
will set our result code to an incorrect value. Evaluate the expression
then test it with `GSS_ERROR` independently to avoid this.

smart_pkt: fix overflow resulting in OOB read/write of one byte
When parsing OK packets, we copy any information after the initial "ok "
prefix into the resulting packet. As newlines act as packet boundaries,
we also strip the trailing newline if there is any. We do not check
whether there is any data left after the initial "ok " prefix though,
which leads to a pointer overflow in that case as `len == 0`:
if (line[len - 1] == '\n')
--len;
This out-of-bounds read is a rather useless gadget, as we can only
deduce whether at some offset there is a newline character. In case
there accidentally is one, we overflow `len` to `SIZE_MAX` and then
write a NUL byte into an array indexed by it:
pkt->ref[len] = '\0';
Again, this doesn't seem like something that's possible to be exploited
in any meaningful way, but it may surely lead to inconsistencies or DoS.
Fix the issue by checking whether there is any trailing data after the
packet prefix.

http: allow dummy negotiation scheme to fail to act
The dummy negotiation scheme is used for known authentication strategies
that do not wish to act. For example, when a server requests the
"Negotiate" scheme but libgit2 is not built with Negotiate support, and
will use the "dummy" strategy which will simply not act.
Instead of setting `out` to NULL and returning a successful code, return
`GIT_PASSTHROUGH` to indicate that it did not act and catch that error
code.

would cause failures when trying to peel a tag to a commit.
Fix the broken filtering by switching to `git_revwalk_push_glob`, which
already handles this case.

In libgit2 nomenclature, when we need to verb a direct object, we name

structure named `git_foo_options`, then the name of the function that
does that should be `git_foo_options_init`.
The previous names of `git_foo_init_options` is close - it _sounds_ as
if it's initializing the options of a `foo`, but in fact
`git_foo_options` is its own noun that should be respected.
Deprecate the old names; they'll now call directly to the new ones.

However, we should continue to remove authentication contexts for
mechanisms with connection affinity (NTLM, Negotiate) since we need to
reauthenticate for every socket connection.

http: simplify authentication mechanisms
Hold an individual authentication context instead of trying to maintain
all the contexts; we can select the preferred context during the initial
negotiation.
Subsequent authentication steps will re-use the chosen authentication
(until such time as it's rejected) instead of trying to manage multiple
contexts when all but one will never be used (since we can only
authenticate with a single mechanism at a time.)
Also, when we're given a 401 or 407 in the middle of challenge/response
handling, short-circuit immediately without incrementing the retry
count. The multi-step authentication is expected, and not a "retry" and
should not be penalized as such.
This means that we don't need to keep the contexts around and ensures
that we do not unnecessarily fail for too many retries when we have
challenge/response auth on a proxy and a server and potentially
redirects in play as well.

Ensure that the server supports the particular credential type that

input to an auth mechanism - since the HTTP transport only supported
default credentials (via negotiate) and username/password credentials
(via basic), this worked. However, if we are to add another mechanism
that uses username/password credentials, we'll need to be careful to
identify the types that are accepted.

http: consume body on proxy auth failure
We must always consume the full parser body if we're going to
keep-alive. So in the authentication failure case, continue advancing
the http message parser until it's complete, then we can retry the
connection.
Not doing so would mean that we have to tear the connection down and
start over. Advancing through fully (even though we don't use the data)
will ensure that we can retry a connection with keep-alive.
|
|
|
75b20458
|
2019-03-07T16:34:55
|
|
http: always consume body on auth failure
When we get an authentication failure, we must consume the entire body
of the response. If we only read half of the body (on the assumption
that we can ignore the rest) then we will never complete the parsing of
the message. This means that we will never set the complete flag, and
our replay must actually tear down the connection and try again.
This is particularly problematic for stateful authentication mechanisms
(SPNEGO, NTLM) that require that we keep the connection alive.
Note that the prior code is only a problem when the 401 that we are
parsing is too large to be read in a single chunked read from the http
parser.
But now we will continue to invoke the http parser until we've got a
complete message in the authentication failed scenario. Note that we
need not do anything with the message, so when we get an authentication
failed, we'll stop adding data to our buffer, we'll simply loop in the
parser and let it advance its internal state.

transports: add an `is_complete` function for auth
Some authentication mechanisms (like HTTP Basic and Digest) have a
one-step mechanism to create credentials, but there are more complex
mechanisms like NTLM and Negotiate that require challenge/response after
negotiation, requiring several round-trips. Add an `is_complete`
function to know when they have round-tripped enough to be a single
authentication and should now either have succeeded or failed to
authenticate.

http: examine keepalive status at message end
We cannot examine the keep-alive status of the http parser in
`http_connect`; it's too late and the critical information about whether
keep-alive is supported has been destroyed.
Per the documentation for `http_should_keep_alive`:
> If http_should_keep_alive() in the on_headers_complete or
> on_message_complete callback returns 0, then this should be
> the last message on the connection.
Query then and set the state.

Increase the permissible replay count; with multiple-step authentication

failure over a redirected multi-state authentication pipeline.

winhttp: support default credentials for proxies
We did not properly support default credentials for proxies, only for
destination servers. Refactor the credential handling to support sending
either username/password _or_ default credentials to either the proxy or
the destination server.
This actually shares the authentication logic between proxy servers and
destination servers. Due to copy/pasta drift over time, they had
diverged. Now they share a common logic which is: first, use
credentials specified in the URL (if there were any), treating empty
username and password (ie, "http://:@foo.com/") as default credentials,
for compatibility with git. Next, call the credential callbacks.
Finally, fallback to WinHTTP compatibility layers using built-in
authentication like we always have.
Allowing default credentials for proxies requires moving the security
level downgrade into the credential setting routines themselves.
We will update our security level to "high" by default which means that
we will never send default credentials without prompting. (A lower
setting, like the WinHTTP default of "medium" would allow WinHTTP to
handle credentials for us, despite what a user may have requested with
their structures.) Now we start with "high" and downgrade to "low" only
after a user has explicitly requested default credentials.

net: rename gitno_connection_data to git_net_url
"Connection data" is an imprecise and largely incorrect name; these
structures are actually parsed URLs. Provide a parser that takes a URL
string and produces a URL structure (if it is valid).
Separate the HTTP redirect handling logic from URL parsing, keeping a
`gitno_connection_data_handle_redirect` whose only job is redirect
handling logic and does not parse URLs itself.

credentials: suffix the callbacks with `_cb`
The credential callbacks should match the other callback naming
conventions, using the `_cb` suffix instead of a `_callback` suffix.

The `git_push_transfer_progress` is a callback and as such should be
suffixed with `_cb` for consistency. Rename

streams: fix callers potentially only writing partial data
Similar to the write(3) function, implementations of `git_stream_write`
do not guarantee that all bytes are written. Instead, they return the
number of bytes that actually have been written, which may be smaller
than the total number of bytes. Furthermore, due to an interface design
issue, we cannot ever write more than `SSIZE_MAX` bytes at once, as
otherwise we cannot represent the number of bytes written to the caller.
Unfortunately, no caller of `git_stream_write` ever checks the return
value, except to verify that no error occurred. Due to this, they are
susceptible to the case where only partial data has been written.
Fix this by introducing a new function `git_stream__write_full`. In
contrast to `git_stream_write`, it will always return either success or
failure, without returning the number of bytes written. Thus, it is able
to write all `SIZE_MAX` bytes and loop around `git_stream_write` until
all data has been written. Adjust all callers except the BIO callbacks
in our mbedtls and OpenSSL streams, which already do the right thing and
require the amount of bytes written.

git transport: only write INT_MAX bytes
The transport code returns an `int` with the number of bytes written;
thus only attempt to write at most `INT_MAX`.

Fix a bunch of warnings
This change fixes a bunch of warnings that were discovered by compiling
with `clang -target=i386-pc-linux-gnu`. It turned out that the
intrinsics were not necessarily being used in all platforms! Especially
in GCC, since it does not support __has_builtin.
Some more warnings were gleaned from the Windows build, but I stopped
when I saw that some third-party dependencies (e.g. zlib) have warnings
of their own, so we might never be able to enable -Werror there.

http: reset replay_count upon connection
Reset the replay_count upon a successful connection. It's possible that
we could encounter a situation where we connect successfully but need to
replay a request - for example, a connection and initial request
succeeds without authentication but a subsequent call does require
authentication. Reset the replay count upon any successful request to
afford subsequent replays room to manuever.

http: only load proxy configuration during connection
Only load the proxy configuration during connection; we need this data
when we're going to connect to the server, however we may mutate it
after connection (connecting through a CONNECT proxy means that we
should send requests like normal). If we reload the proxy configuration
but do not actually reconnect (because we're in a keep-alive session)
then we will reload the proxy configuration that we should have mutated.
Thus, only load the proxy configuration when we know that we're going to
reconnect.

tls: introduce a wrap function
Introduce `git_tls_stream_wrap` which will take an existing `stream`
with an already connected socket and begin speaking TLS on top of it.
This is useful if you've built a connection to a proxy server and you
wish to begin CONNECT over it to tunnel a TLS connection.
Also update the pluggable TLS stream layer so that it can accept a
registration structure that provides an `init` and `wrap` function,
instead of a single initialization function.

http transport: reset error message on cert failure
Store the error message from the underlying TLS library before calling

returning GIT_PASSTHROUGH) then restore the error message. Otherwise,
if the callback does not set an error message, set a sensible default
that implicates the callback itself.
