Edward Thomson e4ac4000 2018-07-02T12:57:56 checkout tests: test symlinks based on support, not platform When testing whether symlinks are correctly checked out, examine the `core.symlinks` configuration option to determine if symlinks are supported in a repository, don't simply assume that Windows means that symbolic links are not supported. Further, when testing the expected default behavior of `core.symlinks`, test the filesystem's support to determine if symlinks are supported. Finally, ensure that `core.symlinks=true` fails on a system where symlinks are actually not supported. This aligns with the behavior of Git for Windows.
Edward Thomson 7b6875f4 2018-07-02T12:25:45 checkout tests: don't use GetFinalPathNameByHandle To determine the canonical filename for a given path, we previously looked at the directory entries on POSIX systems and used GetFinalPathNameByHandle on Windows. However, GetFinalPathNameByHandle requires a HANDLE - the results of CreateFile - and you cannot CreateFile on a symbolic link. To support finding the canonical path of a symbolic link, simply use the existing POSIX code to look at the directory entries.
Edward Thomson b8bdffb5 2018-07-02T07:27:09 cmake: increase WIN32_WINNT to Vista Increase the WIN32_WINNT level to 0x0600, which enables support for new APIs from Windows 6.0 (Vista). We had previously set this to 0x0501, which was Windows XP. Although we removed XP support many years ago, there was no need to update this level previously. We're doing so now explicitly so that we can get support for the `CreateSymbolicLink` API.
Edward Thomson 30771261 2018-07-03T02:21:17 win32: use GetFinalPathNameByHandle directly Now that we've updated to WIN32_WINNT version of Vista or better, we don't need to dynamically load GetFinalPathNameByHandle and can simply invoke it directly.

Patrick Steinhardt a1d5fd06 2018-10-11T12:46:11 fuzzers: add object parsing fuzzer Add a simple fuzzer that exercises our object parser code. The fuzzer is quite trivial in that it simply passes the input data directly to `git_object__from_raw` for each of the four object types.
Patrick Steinhardt 6562cdda 2018-10-11T12:43:08 object: properly propagate errors on parsing failures When failing to parse a raw object fromits data, we free the partially parsed object but then fail to propagate the error to the caller. This may lead callers to operate on objects with invalid memory, which will sooner or later cause the program to segfault. Fix the issue by passing up the error code returned by `parse_raw`.
Patrick Steinhardt 6956a954 2018-10-11T12:26:44 fuzzers: initialize libgit2 in standalone driver The standalone driver for libgit2's fuzzing targets makes use of functions from libgit2 itself. While this is totally fine to do, we need to make sure to always have libgit2 initialized via `git_libgit2_init` before we call out to any of these. While this happens in most cases as we call `LLVMFuzzerInitialize`, which is provided by our fuzzers and which right now always calls `git_libgit2_init`, one exception to this rule is our error path when not enough arguments have been given. In this case, we will call `git_vector_free_deep` without libgit2 having been initialized. As we did not set up our allocation functions in that case, this will lead to a segmentation fault. Fix the issue by always initializing and shutting down libgit2 in the standalone driver. Note that we cannot let this replace the initialization in `LLVMFuzzerInitialize`, as it is required when using the "real" fuzzers by LLVM without our standalone driver. It's no problem to call the initialization and deinitialization functions multiple times, though.

Carlos Martín Nieto c8ca3cae 2018-10-05T11:47:39 submodule: ignore path and url attributes if they look like options These can be used to inject options in an implementation which performs a recursive clone by executing an external command via crafted url and path attributes such that it triggers a local executable to be run. The library is not vulnerable as we do not rely on external executables but a user of the library might be relying on that so we add this protection. This matches this aspect of git's fix for CVE-2018-17456.

Patrick Steinhardt ad273718 2018-10-04T10:32:07 tests: sanitize file hierarchy after running rmdir tests Currently, we do not clean up after ourselves after tests in core::rmdir have created new files in the directory hierarchy. This may leave stale files and/or directories after having run tests, confusing subsequent tests that expect a pristine test environment. Most importantly, it may cause the test initialization to fail which expects being able to re-create the testing hierarchy before each test in case where another test hasn't cleaned up after itself. Fix the issue by adding a cleanup function that removes the temporary testing hierarchy after each test if it still exists.

Patrick Steinhardt d06d4220 2018-10-05T10:56:02 config_file: properly ignore includes without "path" value In case a configuration includes a key "include.path=" without any value, the generated configuration entry will have its value set to `NULL`. This is unexpected by the logic handling includes, and as soon as we try to calculate the included path we will unconditionally dereference that `NULL` pointer and thus segfault. Fix the issue by returning early in both `parse_include` and `parse_conditional_include` in case where the `file` argument is `NULL`. Add a test to avoid future regression. The issue has been found by the oss-fuzz project, issue 10810.
Patrick Steinhardt bf662f7c 2018-10-05T10:55:29 tests: always unlink created config files While our tests in config::include create a plethora of configuration files, most of them do not get removed at the end of each test. This can cause weird interactions with tests that are being run at a later stage if these later tests try to create files or directories with the same name as any of the created configuration files. Fix the issue by unlinking all created files at the end of these tests.
Patrick Steinhardt aa0ae59a 2018-10-05T10:31:53 cmake: explicitly enable int-conversion warnings While GCC enables int-conversion warnings by default, it will currently only warn about such errors even in case where "-DENABLE_WERROR=ON" has been passed to CMake. Explicitly enable int-conversion warnings by using our `ENABLE_WARNINGS` macro, which will automatically use "-Werror=int-conversions" in case it has been requested by the user.
Patrick Steinhardt dbb4a586 2018-10-05T10:27:33 tests: fix warning for implicit conversion of integer to pointer GCC warns by default when implicitly converting integers to pointers or the other way round, and commit fa48d2ea7 (vector: do not malloc 0-length vectors on dup, 2018-09-26) introduced such an implicit conversion into our vector tests. While this is totally fine in this test, as the pointer's value is never being used in the first place, we can trivially avoid the warning by instead just inserting a pointer for a variable allocated on the stack into the vector.

Patrick Steinhardt e5090ee3 2018-10-04T11:19:28 diff_stats: use git's formatting of renames with common directories In cases where a file gets renamed such that the directories containing it previous and after the rename have a common prefix, then git will avoid printing this prefix twice and instead format the rename as "prefix/{old => new}". We currently didn't do anything like that, but simply printed "prefix/old -> prefix/new". Adjust our behaviour to instead match upstream. Adjust the test for this behaviour to expect the new format.
Patrick Steinhardt 3148efd2 2018-10-04T11:13:57 tests: verify diff stats with renames in subdirectory Until now, we didn't have any tests that verified that our format for renames in subdirectories is correct. While our current behaviour is no different than for renames that do not happen with a common prefix shared between old and new file name, we intend to change the format to instead match the format that upstream git uses. Add a test case for this to document our current behaviour and to show how the next commit will change that format.
Patrick Steinhardt 633584b5 2018-10-04T10:48:12 cmake: enable new quoted argument policy CMP0054 Quoting from CMP0054's documentation: Only interpret if() arguments as variables or keywords when unquoted. CMake 3.1 and above no longer implicitly dereference variables or interpret keywords in an if() command argument when it is a Quoted Argument or a Bracket Argument. The OLD behavior for this policy is to dereference variables and interpret keywords even if they are quoted or bracketed. The NEW behavior is to not dereference variables or interpret keywords that have been quoted or bracketed. The previous behaviour could be quite unexpected. Quoted arguments might be expanded in case where the value of the argument corresponds to a variable. E.g. `IF("MONKEY" STREQUAL "MONKEY")` would have been expanded to `IF("1" STREQUAL "1")` iff `SET(MONKEY 1)` was set. This behaviour was weird, and recent CMake versions have started to complain about this if they see ambiguous situations. Thus we want to disable it in favor of the new behaviour.
Patrick Steinhardt 04d3853f 2018-10-04T10:47:29 cmake: remove spaces between `IF` and `(` for policies Our CMake coding style dictates that there should be no space between `IF` and its opening `(`. Adjust our policy statements to honor this style.

Patrick Steinhardt 1bc5b05c 2018-10-03T16:17:21 smart_pkt: do not accept callers passing in no line length Right now, we simply ignore the `linelen` parameter of `git_pkt_parse_line` in case the caller passed in zero. But in fact, we never want to assume anything about the provided buffer length and always want the caller to pass in the available number of bytes. And in fact, checking all the callers, one can see that the funciton is never being called in case where the buffer length is zero, and thus we are safe to remove this check.
Patrick Steinhardt c05790a8 2018-08-09T11:16:15 smart_pkt: return parsed length via out-parameter The `parse_len` function currently directly returns the parsed length of a packet line or an error code in case there was an error. Instead, convert this to our usual style of using the return value as error code only and returning the actual value via an out-parameter. Thus, we can now convert the output parameter to an unsigned type, as the size of a packet cannot ever be negative. While at it, we also move the check whether the input buffer is long enough into `parse_len` itself. We don't really want to pass around potentially non-NUL-terminated buffers to functions without also passing along the length, as this is dangerous in the unlikely case where other callers for that function get added. Note that we need to make sure though to not mess with `GIT_EBUFS` error codes, as these indicate not an error to the caller but that he needs to fetch more data.
Patrick Steinhardt 0b3dfbf4 2018-08-09T11:13:59 smart_pkt: reorder and rename parameters of `git_pkt_parse_line` The parameters of the `git_pkt_parse_line` function are quite confusing. First, there is no real indicator what the `out` parameter is actually all about, and it's not really clear what the `bufflen` parameter refers to. Reorder and rename the parameters to make this more obvious.
Patrick Steinhardt 5fabaca8 2018-08-09T11:04:42 smart_pkt: fix buffer overflow when parsing "unpack" packets When checking whether an "unpack" packet returned the "ok" status or not, we use a call to `git__prefixcmp`. In case where the passed line isn't properly NUL terminated, though, this may overrun the line buffer. Fix this by using `git__prefixncmp` instead.
Patrick Steinhardt b5ba7af2 2018-08-09T11:03:37 smart_pkt: fix "ng" parser accepting non-space character When parsing "ng" packets, we blindly assume that the character immediately following the "ng" prefix is a space and skip it. As the calling function doesn't make sure that this is the case, we can thus end up blindly accepting an invalid packet line. Fix the issue by using `git__prefixncmp`, checking whether the line starts with "ng ".
Patrick Steinhardt a9f1ca09 2018-08-09T11:01:00 smart_pkt: fix buffer overflow when parsing "ok" packets There are two different buffer overflows present when parsing "ok" packets. First, we never verify whether the line already ends after "ok", but directly go ahead and also try to skip the expected space after "ok". Second, we then go ahead and use `strchr` to scan for the terminating newline character. But in case where the line isn't terminated correctly, this can overflow the line buffer. Fix the issues by using `git__prefixncmp` to check for the "ok " prefix and only checking for a trailing '\n' instead of using `memchr`. This also fixes the issue of us always requiring a trailing '\n'. Reported by oss-fuzz, issue 9749: Crash Type: Heap-buffer-overflow READ {*} Crash Address: 0x6310000389c0 Crash State: ok_pkt git_pkt_parse_line git_smart__store_refs Sanitizer: address (ASAN)
Patrick Steinhardt bc349045 2018-08-09T10:38:10 smart_pkt: fix buffer overflow when parsing "ACK" packets We are being quite lenient when parsing "ACK" packets. First, we didn't correctly verify that we're not overrunning the provided buffer length, which we fix here by using `git__prefixncmp` instead of `git__prefixcmp`. Second, we do not verify that the actual contents make any sense at all, as we simply ignore errors when parsing the ACKs OID and any unknown status strings. This may result in a parsed packet structure with invalid contents, which is being silently passed to the caller. This is being fixed by performing proper input validation and checking of return codes.
Patrick Steinhardt 5edcf5d1 2018-08-09T10:57:06 smart_pkt: adjust style of "ref" packet parsing function While the function parsing ref packets doesn't have any immediately obvious buffer overflows, it's style is different to all the other parsing functions. Instead of checking buffer length while we go, it does a check up-front. This causes the code to seem a lot more magical than it really is due to some magic constants. Refactor the function to instead make use of the style of other packet parser and verify buffer lengths as we go.
Patrick Steinhardt 786426ea 2018-08-09T10:46:58 smart_pkt: check whether error packets are prefixed with "ERR " In the `git_pkt_parse_line` function, we determine what kind of packet a given packet line contains by simply checking for the prefix of that line. Except for "ERR" packets, we always only check for the immediate identifier without the trailing space (e.g. we check for an "ACK" prefix, not for "ACK "). But for "ERR" packets, we do in fact include the trailing space in our check. This is not really much of a problem at all, but it is inconsistent with all the other packet types and thus causes confusion when the `err_pkt` function just immediately skips the space without checking whether it overflows the line buffer. Adjust the check in `git_pkt_parse_line` to not include the trailing space and instead move it into `err_pkt` for consistency.
Patrick Steinhardt 40fd84cc 2018-08-09T10:46:26 smart_pkt: explicitly avoid integer overflows when parsing packets When parsing data, progress or error packets, we need to copy the contents of the rest of the current packet line into the flex-array of the parsed packet. To keep track of this array's length, we then assign the remaining length of the packet line to the structure. We do have a mismatch of types here, as the structure's `len` field is a signed integer, while the length that we are assigning has type `size_t`. On nearly all platforms, this shouldn't pose any problems at all. The line length can at most be 16^4, as the line's length is being encoded by exactly four hex digits. But on a platforms with 16 bit integers, this assignment could cause an overflow. While such platforms will probably only exist in the embedded ecosystem, we still want to avoid this potential overflow. Thus, we now simply change the structure's `len` member to be of type `size_t` to avoid any integer promotion.
Patrick Steinhardt 4a5804c9 2018-08-09T10:36:44 smart_pkt: honor line length when determining packet type When we parse the packet type of an incoming packet line, we do not verify that we don't overflow the provided line buffer. Fix this by using `git__prefixncmp` instead and passing in `len`. As we have previously already verified that `len <= linelen`, we thus won't ever overflow the provided buffer length.
Patrick Steinhardt 365d2720 2018-10-03T15:39:40 tests: verify parsing logic for smart packets The commits following this commit are about to introduce quite a lot of refactoring and tightening of the smart packet parser. Unfortunately, we do not yet have any tests despite our online tests that verify that our parser does not regress upon changes. This is doubly unfortunate as our online tests aren't executed by default. Add new tests that exercise the smart parsing logic directly by executing `git_pkt_parse_line`.

Carlos Martín Nieto 0530d7d9 2018-09-28T18:04:23 Merge pull request #4767 from pks-t/pks/config-mem In-memory configuration
Patrick Steinhardt 2be39cef 2018-08-10T19:38:57 config: introduce new read-only in-memory backend Now that we have abstracted away how to store and retrieve config entries, it became trivial to implement a new in-memory backend by making use of this. And thus we do so. This commit implements a new read-only in-memory backend that can parse a chunk of memory into a `git_config_backend` structure.
Patrick Steinhardt b78f4ab0 2018-08-16T12:22:03 config_entries: refactor entries iterator memory ownership Right now, the config file code requires us to pass in its backend to the config entry iterator. This is required with the current code, as the config file backend will first create a read-only snapshot which is then passed to the iterator just for that purpose. So after the iterator is getting free'd, the code needs to make sure that the snapshot gets free'd, as well. By now, though, we can easily refactor the code to be more efficient and remove the reverse dependency from iterator to backend. Instead of creating a read-only snapshot (which also requires us to re-parse the complete configuration file), we can simply duplicate the config entries and pass those to the iterator. Like that, the iterator only needs to make sure to free the duplicated config entries, which is trivial to do and clears up memory ownership by a lot.
Patrick Steinhardt d49b1365 2018-08-10T19:01:37 config_entries: internalize structure declarations Access to the config entries is now completely done via the modules function interface and no caller messes with the struct's internals. We can thus completely move the structure declarations into the implementation file so that nobody even has a chance to mess with the members.
Patrick Steinhardt 123e5963 2018-08-10T18:59:59 config_entries: abstract away reference counting Instead of directly calling `git_atomic_inc` in users of the config entries store, provide a `git_config_entries_incref` function to further decouple the interfaces. Convert the refcount to a `git_refcount` structure while at it.
Patrick Steinhardt 5a7e0b3c 2018-08-10T18:49:38 config_entries: abstract away iteration over entries The nice thing about our `git_config_iterator` interfaces is that nobody needs to know anything about the implementation details. All that is required is to obtain the iterator via any backend and then use it by executing generic functions. We can thus completely internalize all the implementation details of how to iterate over entries into the config entries store and simply create such an iterator in our config file backend when we want to iterate its entries. This further decouples the config file backend from the config entries store.
Patrick Steinhardt 60ebc137 2018-08-10T14:53:09 config_entries: abstract away retrieval of config entries The code accessing config entries in the `git_config_entries` structure is still much too intimate with implementation details, directly accessing the maps and handling indices. Provide two new functions to get config entries from the internal map structure to decouple the interfaces and use them in the config file code. The function `git_config_entries_get` will simply look up the entry by name and, in the case of a multi-value, return the last occurrence of that entry. The second function, `git_config_entries_get_unique`, will only return an entry if it is unique and not included via another configuration file. This one is required to properly implement write operations for single entries, as we refuse to write to or delete a single entry if it is not clear which one was meant.
Patrick Steinhardt fb8a87da 2018-08-10T14:50:15 config_entries: rename functions and structure The previous commit simply moved all code that is required to handle config entries to a new module without yet adjusting any of the function and structure names to help readability. We now rename things accordingly to have a common "git_config_entries" entries instead of the old "diskfile_entries" one.
Patrick Steinhardt 04f57d51 2018-08-10T13:33:02 config_entries: pull out implementation of entry store The configuration entry store that is used for configuration files needs to keep track of all entries in two different structures: - a singly linked list is being used to be able to iterate through configuration files in the order they have been found - a string map is being used to efficiently look up configuration entries by their key This store is thus something that may be used by other, future backends as well to abstract away implementation details and iteration over the entries. Pull out the necessary functions from "config_file.c" and moves them into their own "config_entries.c" module. For now, this is simply moving over code without any renames and/or refactorings to help reviewing.
Patrick Steinhardt d75bbea1 2018-08-10T14:35:23 config_file: remove unnecessary snapshot indirection The implementation for config file snapshots has an unnecessary redirection from `config_snapshot` to `git_config_file__snapshot`. Inline the call to `git_config_file__snapshot` and remove it.
Patrick Steinhardt b944e137 2018-08-10T13:03:33 config: rename "config_file.h" to "config_backend.h" The header "config_file.h" has a list of inline-functions to access the contents of a config backend without directly messing with the struct's function pointers. While all these functions are called "git_config_file_*", they are in fact completely backend-agnostic and don't care whether it is a file or not. Rename all the function to instead be backend-agnostic versions called "git_config_backend_*" and rename the header to match.
Patrick Steinhardt 1aeff5d7 2018-08-10T12:52:18 config: move function normalizing section names into "config.c" The function `git_config_file_normalize_section` is never being used in any file different than "config.c", but it is implemented in "config_file.c". Move it over and make the symbol static.
Patrick Steinhardt a5562692 2018-08-10T12:49:50 config: make names backend-agnostic As a last step to make variables and structures more backend agnostic for our `git_config` structure, rename local variables to not be called `file` anymore.

Patrick Steinhardt 83733aeb 2018-08-10T12:43:21 config: rename `file_internal` and its `file` member Same as with the previous commit, the `file_internal` struct is used to keep track of all the backends that are added to a `git_config` struct. Rename it to `backend_internal` and rename its `file` member to `backend` to make the implementation more backend-agnostic.
Patrick Steinhardt 633cf40c 2018-08-10T12:39:17 config: rename `files` vector to `backends` Originally, the `git_config` struct is a collection of all the parsed configuration files from different scopes (system-wide config, user-specific config as well as the repo-specific config files). Historically, we didn't and don't yet have any other configuration backends than the one for files, which is why the field holding the config backends is called `files`. But in fact, nothing dictates that the vector of backends actually holds file backends only, as they are generic and custom backends can be implemented by users. Rename the member to be called `backends` to clarify that there is nothing specific to files here.
Patrick Steinhardt b9affa32 2018-08-10T19:23:00 config_parse: avoid unused static declared values The variables `git_config_escaped` and `git_config_escapes` are both defined as static const character pointers in "config_parse.h". In case where "config_parse.h" is included but those two variables are not being used, the compiler will thus complain about defined but unused variables. Fix this by declaring them as external and moving the actual initialization to the C file. Note that it is not possible to simply make this a #define, as we are indexing into those arrays.
Patrick Steinhardt 0b9c68b1 2018-08-16T14:10:58 submodule: fix submodule names depending on config-owned memory When populating the list of submodule names, we use the submodule configuration entry's name as the key in the map of submodule names. This creates a hidden dependency on the liveliness of the configuration that was used to parse the submodule, which is fragile and unexpected. Fix the issue by duplicating the string before writing it into the submodule name map.
