Leakfix. * jk/connect-symref-info-leak-fix: connect.c: fix leak in parse_one_symref_info()
2017-05-26connect.c: fix leak in parse_one_symref_info()Libravatar Jeff King1-1/+1
If we successfully parse a symref value like "HEAD:refs/heads/master", we add the result to a string list. But because the string list is marked STRING_LIST_INIT_DUP, the string list code will make a copy of the string and add the copy. This patch fixes it by adding the entry with string_list_append_nodup(), which lets the string list take ownership of our newly allocated string. There are two alternatives that seem like they would work, but aren't the right solution. The first is to initialize the list with the "NODUP" initializer. That would avoid the copy, but then the string list would not realize that it owns the strings. When we eventually call string_list_clear(), it would not free the strings, causing a leak. The second option would be to use the normal string_list_append(), but free the local copy in our function. We can't do this because the local copy actually contains _two_ strings; the symref name and its target. We point to the target pointer via the "util" field, and its memory must last as long as the string list does. You may also wonder whether it's safe to ever free the local copy, since the target points into it. The answer is yes, because we duplicate it in annotaate_refs_with_symref_info before clearing the string list.

When we see an error from split_cmdline(), we exit the function without freeing the copy of the command string we made.

2017-04-16connect.c: handle errors from split_cmdlineLibravatar Jeff King1-1/+1
Commit e9d9a8a4d (connect: handle putty/plink also in GIT_SSH_COMMAND, 2017-01-02) added a call to split_cmdline(), but checks only for a non-zero return to see if we got any output. Since the function returns negative values (and a NULL argv) on error, we end up dereferencing NULL and segfaulting. Arguably we could report on the parsing error here, but it's probably not worth it. This is a best-effort attempt to see if we are using plink. So we can simply return here with "no, it wasn't plink" and let the shell actually complain about the bogus quoting.

2017-02-10connect.c: stop conflating ssh command names and overridesLibravatar Junio C Hamano1-13/+32
dd33e07766 ("connect: Add the envvar GIT_SSH_VARIANT and ssh.variant config", 2017-02-01) attempted to add support for configuration and environment variable to override the different handling of port_option and needs_batch settings suitable for variants of the ssh implementation that was autodetected by looking at the ssh command name. Because it piggybacked on the code that turns command name to specific override (e.g. "plink.exe" and "plink" means port_option needs to be set to 'P' instead of the default 'p'), yet it defined a separate namespace for these overrides (e.g. "putty" can be usable to signal that port_option needs to be 'P'), however, it made the auto-detection based on the command name less robust (e.g. the code now accepts "putty" as a SSH command name and applies the same override). Separate the code that interprets the override that was read from the configuration & environment from the original code that handles the command names, as they are in separate namespaces, to fix this confusion. This incidentally also makes it easier for future enhancement of the override syntax (e.g. "port_option=p,needs_batch=1" may want to be accepted as a more explicit syntax) without affecting the code for auto-detection based on the command name. While at it, update the return type of the handle_ssh_variant() helper function to void; the caller does not use it, and the function does not return any meaningful value.

2017-01-26connect: rename tortoiseplink and putty variablesLibravatar Junio C Hamano1-10/+13
One of these two may have originally been named after "what exact SSH implementation do we have?" so that we can tweak the command line options for that exact implementation. But "putty=1" no longer means "We are using the plink SSH implementation that comes with PuTTY" these days. It is set when we guess that either PuTTY plink or Tortoiseplink is in use. Rename them after what effect is desired. The current 'putty' option is about using "-P <port>" when OpenSSH would use "-p <port>", so rename it to 'port_option' whose value is either 'p' or 'P". The other one is about passing an extra command line option "-batch", so rename it to 'needs_batch'.

2017-01-25connect: handle putty/plink also in GIT_SSH_COMMANDLibravatar Segev Finer1-7/+16
Git for Windows has special support for the popular SSH client PuTTY: when using PuTTY's non-interactive version ("plink.exe"), we use the -P option to specify the port rather than OpenSSH's -p option. TortoiseGit ships with its own, forked version of plink.exe, that adds support for the -batch option, and for good measure we special-case that, too. However, this special-casing of PuTTY only covers the case where the user overrides the SSH command via the environment variable GIT_SSH (which allows specifying the name of the executable), not GIT_SSH_COMMAND (which allows specifying a full command, including additional command-line options). When users want to pass any additional arguments to (Tortoise-)Plink, such as setting a private key, they are required to either use a shell script named plink or tortoiseplink or duplicate the logic that is already in Git for passing the correct style of command line arguments, which can be difficult, error prone and annoying to get right. This patch simply reuses the existing logic and expands it to cover GIT_SSH_COMMAND, too. Note: it may look a little heavy-handed to duplicate the entire command-line and then split it, only to extract the name of the executable. However, this is not a performance-critical code path, and the code is much more readable this way.

2016-09-09connect: advertized capability is not a refLibravatar Jonathan Tan1-0/+14
When cloning an empty repository served by standard git, "git clone" produces the following reassuring message: $ git clone git://localhost/tmp/empty Cloning into 'empty'... warning: You appear to have cloned an empty repository. Checking connectivity... done. Meanwhile when cloning an empty repository served by JGit, the output is more haphazard: $ git clone git://localhost/tmp/empty Cloning into 'empty'... Checking connectivity... done. warning: remote HEAD refers to nonexistent ref, unable to checkout. This is a common command to run immediately after creating a remote repository as preparation for adding content to populate it and pushing. The warning is confusing and needlessly worrying. The cause is that, since v3.1.0.201309270735-rc1~22 (Advertise capabilities with no refs in upload service., 2013-08-08), JGit's ref advertisement includes a ref named capabilities^{} to advertise its capabilities on, while git's ref advertisement is empty in this case. This allows the client to learn about the server's capabilities and is needed, for example, for fetch-by-sha1 to work when no refs are advertised. This also affects "ls-remote". For example, against an empty repository served by JGit: $ git ls-remote git://localhost/tmp/empty 0000000000000000000000000000000000000000 capabilities^{} Git advertises the same capabilities^{} ref in its ref advertisement for push but since it never did so for fetch, the client didn't need to handle this case.

A server hanging up immediately to mark access being denied does not send any .have refs, shallow lines, or anything else before hanging up. If the server has sent anything, then the hangup is unexpected. That is, if the server hangs up after a shallow line but before sending any refs, then git should tell me so: fatal: The remote end hung up upon initial contact instead of suggesting an access control problem: fatal: Could not read from remote repository.

We sometimes sprintf into fixed-size buffers when we know that the buffer is large enough to fit the input (either because it's a constant, or because it's numeric input that is bounded in size). Likewise with strcpy of constant strings. However, these sites make it hard to audit sprintf and strcpy calls for buffer overflows, as a reader has to cross-reference the size of the array with the input.

2015-09-23transport: add a protocol-whitelist environment variableLibravatar Jeff King1-0/+5
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. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-09-08git_connect: clarify conn->use_shell flagLibravatar Jeff King1-9/+13
When executing user-specified programs, we generally always want to use a shell, for flexibility and consistency. One big exception is executing $GIT_SSH, which for historical reasons must not use a shell. Once upon a time the logic in git_connect looked like: if (protocol == PROTO_SSH) { ... setup ssh ... } else { ... setup local connection ... conn->use_shell = 1; } But over time the PROTO_SSH block has grown, and the "local" block has shrunk so that it contains only conn->use_shell; it's easy to miss at the end of the large block. Moreover, PROTO_SSH now also sometimes sets use_shell, when the new GIT_SSH_COMMAND is used. Let's just set conn->use_shell when we're setting up the "conn" struct, and unset it (with a comment) in the historical GIT_SSH case. This will make the flow easier to follow.

2015-09-04git_connect: clear GIT_* environment for sshLibravatar Jeff King1-2/+2
When we "switch" to another local repository to run the server side of a fetch or push, we must clear the variables in local_repo_env so that our local $GIT_DIR, etc, do not pollute the upload-pack or receive-pack that is executing in the "remote" repository. We have never done so for ssh connections. For the most part, nobody has noticed because ssh will not pass unknown environment variables by default. However, it is not out of the question for a user to configure ssh to pass along GIT_* variables using SendEnv/AcceptEnv. We can demonstrate the problem by using "git -c" on a local command and seeing its impact on a remote repository. This config ends up in $GIT_CONFIG_PARAMETERS. In the local case, the config has no impact, but in the ssh transport, it does (our test script has a fake ssh that passes through all environment variables; this isn't normal, but does simulate one possible setup).

2015-04-28connect: improve check for plink to reduce false positivesLibravatar brian m. carlson1-3/+15
The git_connect function has code to handle plink and tortoiseplink specially, as they require different command line arguments from OpenSSH (-P instead of -p for ports; tortoiseplink additionally requires -batch). However, the match was done by checking for "plink" anywhere in the string, which led to a GIT_SSH value containing "uplink" being treated as an invocation of putty's plink. Improve the check by looking for "plink" or "tortoiseplink" (or those names suffixed with ".exe") only in the final component of the path. This has the downside that a program such as "plink-0.63" would no longer be recognized, but the increased robustness is likely worth it. Add tests to cover these cases to avoid regressions.

It had been working for URLs with ssh:// scheme, but was unintentionally broken in 86ceb3, "allow ssh://user@[2001:db8::1]/repo.git" Reported-by: Reid Woodbury Jr. <reidw@rawsound.com> Signed-off-by: Torsten Bögershausen <tboegi@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

We did not parse username followed by literal IPv6 address in SSH transport URLs, e.g. ssh://user@[2001:db8::1]:22/repo.git correctly. * tb/connect-ipv6-parse-fix: t5500: show user name and host in diag-url t5601: add more test cases for IPV6 connect.c: allow ssh://user@[2001:db8::1]/repo.git

The "interpolated-path" option of "git daemon" inserted any string client declared on the "host=" capability request without checking. Sanitize and limit %H and %CH to a saner and a valid DNS name. * jk/daemon-interpolate: daemon: sanitize incoming virtual hostname t5570: test git-daemon's --interpolated-path option git_connect: let user override virtual-host we send to daemon
2015-03-10connect.c: do not leak "conn" after showing diagnosisLibravatar Stefan Beller1-0/+1
When git_connect() is called to see how the URL is parsed for debugging purposes with CONNECT_DIAG_URL set, the variable conn is leaked. At this point in the codeflow, it only has its memory and no other resource is associated with it, so it is sufficient to clean it up by just freeing it.
