* daemon: deglobalize hostname informationrs/daemon-hostname-in-strbufRené Scharfe2015-03-091-59/+74
| | | | | | | | | | | | | | | | Move the variables related to the client-supplied hostname into its own struct, let execute() own an instance of that instead of storing the information in global variables and pass the struct to any function that needs to access it as a parameter. The lifetime of the variables is easier to see this way. Allocated memory is released within execute(). The strbufs don't have to be reset anymore because they are written to only once at most: parse_host_arg() is only called once by execute() and lookup_hostname() guards against being called twice using hostname_lookup_done.

* daemon: use strbuf for hostname infoRené Scharfe2015-03-091-57/+41
| | | | | | | | | | | | | Convert hostname, canon_hostname, ip_address and tcp_port to strbuf. This allows to get rid of the helpers strbuf_addstr_or_null() and STRARG because a strbuf always represents a valid (initially empty) string. sanitize_client() is not needed anymore and sanitize_client_strbuf() takes its place and name.

| * daemon: sanitize incoming virtual hostnamejk/daemon-interpolateJeff King2015-02-172-5/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use the daemon_avoid_alias function to make sure that the pathname the user gives us is sane. However, after applying that check, we might then interpolate the path using a string given by the server admin, but which may contain more untrusted data from the client. We should be sure to sanitize this data, as well. We cannot use daemon_avoid_alias here, as it is more strict than we need in requiring a leading '/'. At the same time, we can be much more strict here. We are interpreting a hostname, which should not contain slashes or excessive runs of dots, as those things are not allowed in DNS names. Note that in addition to cleansing the hostname field, we must check the "canonical hostname" (%CH) as well as the port (%P), which we take as a raw string. For the canonical hostname, this comes from an actual DNS lookup on the accessed IP, which makes it a much less likely vector for problems. But it does not hurt to sanitize it in the same way. Unfortunately we cannot test this case easily, as it would involve a custom hostname lookup. We do not need to check %IP, as it comes straight from inet_ntop, so must have a sane form.

| * git_connect: let user override virtual-host we send to daemonJeff King2015-02-171-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we connect to a git-daemon at a given host and port, we actually send the string "localhost:9418" to the other side, which allows it to do virtual-hosting lookups. For testing and debugging, we'd like to be able to send arbitrary strings, rather than the hostname we actually connected to. Using "insteadOf" config does not work for this purpose, as the hostname determination happens at a very low level, right before we feed the hostname to our lookup routines. You could use /etc/hosts or similar to get around this, but we cannot do that portably from our test suite. Instead, this patch provides an environment variable that can be used to send an arbitrary string. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Detect and reject such a patch. Things to note: - Unfortunately, we cannot reuse the has_symlink_leading_path() from dir.c, as that is only about the working tree, but "git apply" can be told to apply the patch only to the index or to both the index and to the working tree. - We cannot directly use has_symlink_leading_path() even when we are applying only to the working tree, as an early patch of a valid input may remove a symbolic link path/to/dir and then a later patch of the input may create a path path/to/dir/file, but "git apply" first checks the input without touching either the index or the working tree. The leading symbolic link check must be done on the interim result we compute in-core (i.e. after the first patch, there is no path/to/dir symbolic link and it is perfectly valid to create path/to/dir/file). Similarly, when an input creates a symbolic link path/to/dir and then creates a file path/to/dir/file, we need to flag it as an error without actually creating path/to/dir symbolic link in the filesystem. Instead, for any patch in the input that leaves a path (i.e. a non deletion) in the result, we check all leading paths against the resulting tree that the patch would create by inspecting all the patches in the input and then the target of patch application (either the index or the working tree). This way, we catch a mischief or a mistake to add a symbolic link path/to/dir and a file path/to/dir/file at the same time, while allowing a valid patch that removes a symbolic link path/to/dir and then adds a file path/to/dir/file.

Git itself does not create such a patch, unless the user bends over backwards and specifies a non-standard prefix to "git diff" and friends. When `git apply` is used as a "better GNU patch", the user can pass the `--unsafe-paths` option to override this safety check. This option has no effect when `--index` or `--cached` is in use. The new test was stolen from Jeff King with slight enhancements. Note that a few new tests for touching outside the working area by following a symbolic link are still expected to fail at this step, but will be fixed in later steps.

Some filesystems cannot satisify this. SANITY requires that a file or a directory is indeed accessible (or inaccessible) when its permission bits would say it ought to be accessible (or inaccessible). Running tests as root would lose this prerequisite for obvious reasons. Fix a few tests that misuse POSIXPERM. t0061-run-command.sh has two uses of POSIXPERM. - One checks that an attempt to execute a file that is marked as unexecutable results in a failure with EACCES; I do not think having root-ness or any other capability that busts the filesystem permission mode bits will make you run an unexecutable file, so this should be left as-is. The test does not have anything to do with SANITY. - The other one expects 'git nitfol' runs the alias when an alias.nitfol is defined and a directory on the PATH is marked as unreadable and unsearchable. I _think_ the test tries to reject the alternative expectation that we want to refuse to run the alias because it would break "no alias may mask a command" rule if a file 'git-nitfol' exists in the unreadable directory but we cannot even determine if that is the case. Under !SANITY that busts the permission bits, this test no longer checks that, so it must be protected with SANITY. t1509-root-worktree.sh expects to be run on a / that is writable by the user and sees if Git behaves "sensibly" when /.git is the repository to govern a worktree that is the whole filesystem, and also if Git behaves "sensibly" when / itself is a bare repository with refs, objects, and friends (I find the definition of "behaves sensibly" under these conditions hard to fathom, but it is a different matter). The implementation of the test is very much problematic. - It requires POSIXPERM, but it does not do chmod or checks modes in any way. - It runs "rm /*" and "rm -fr /refs /objects ..." in one of the tests, and also does "cd / && git init --bare". If done on a live system that takes advantages of the "feature" being tested, these obviously will clobber the system.

But the httpd tests really just care about not being root, as they are trying to avoid weirdness in apache (see a1a3011 for details). Let's switch out SANITY for a new NOT_ROOT prerequisite, which will let us tweak SANITY more freely. We implement NOT_ROOT by checking `id -u`, which is in POSIX and seems to be available even on MSYS. Note that we cannot just call this "ROOT" and ask for "!ROOT". The possible outcomes are: 1. we know we are root 2. we know we are not root 3. we could not tell, because `id` was not available We should conservatively treat (3) as "does not have the prerequisite", which means that a naive negation would not work.

If this process fails, we call die() and end up in our die_nicely() handler. Which unfortunately includes running end_packfile to save any progress we made. We enter the function again, and start operating on the pack_data struct while it is in an inconsistent state, leading to a segfault. One way to trigger this is to simply start two identical fast-imports at the same time. They will both create the same packfiles, which will then try to create identically named ".keep" files. One will win the race, and the other will die(), and end up with the segfault. Since 3c078b9, we already reset the pack_data pointer to NULL at the end of end_packfile. That covers the case of us calling die() right after end_packfile, before we have reinitialized the pack_data pointer. This new problem is quite similar, except that we are worried about calling die() _during_ end_packfile, not right after. Ideally we would simply set pack_data to NULL as soon as we enter the function, and operate on a copy of the pointer. Unfortunately, it is not so easy. pack_data is a global, and end_packfile calls into other functions which operate on the global directly. We would have to teach each of these to take an argument, and there is no guarantee that we would catch all of the spots. Instead, we can simply use a static flag to avoid recursively entering the function. This is a little less elegant, but it's short and fool-proof.

This also brought our IO below SSIZE_MAX, which is a limit POSIX allows read(2) and write(2) to fail when the IO size exceeds it, for OS X, where a problem was originally reported. However, there are other systems that define SSIZE_MAX smaller than our default, and feeding 8 MiB to underlying read(2)/write(2) would fail. Make sure we clip our calls to the lower limit as well.

This makes it annoying to find the appropriate documentation. We'd rather have it all in one place, which means all in the text document, or all in the header. Let's choose the header as that place. Even though the formatting is not quite as pretty, this keeps the documentation close to the related code. The hope is that this makes it easier to find what you want (human-readable comments are right next to the C declarations), and easier for writers to keep the documentation up to date. This is more or less a straight import of the text from api-strbuf.txt into C comments, complete with asciidoc formatting. The exceptions are: 1. All comments created in this way are started with "/**" to indicate they are part of the API documentation. This may help later with extracting the text to pretty-print it. 2. Function descriptions do not repeat the function name, as it is available in the context directly below. So: `strbuf_add`:: Add data of given length to the buffer. from api-strbuf.txt becomes: /** * Add data of given length to the buffer. */ void strbuf_add(struct strbuf *sb, const void *, size_t); As a result, any block-continuation required in asciidoc for that list item was dropped in favor of straight blank-line paragraph (since it is not necessary when we are not in a list item). 3. There is minor re-wording to integrate existing comments and api-strbuf text. In each case, I took whichever version was more descriptive, and eliminated any redundancies. In one case, for strbuf_addstr, the api documentation gave its inline definition; I eliminated this as redundant with the actual definition, which can be seen directly below the comment. 4. The functions in the header file are re-ordered to match the ordering of the API documentation, under the assumption that more thought went into the grouping there.
