Etienne Samson aa234ac0 2019-09-21T08:47:01 util: hide helper qsort code to silence unused functions warning
Patrick Steinhardt 8cbef12d 2019-08-08T11:52:54 util: do not perform allocations in insertsort Our hand-rolled fallback sorting function `git__insertsort_r` does an in-place sort of the given array. As elements may not necessarily be pointers, it needs a way of swapping two values of arbitrary size, which is currently implemented by allocating a temporary buffer of the element's size. This is problematic, though, as the emulated `qsort` interface doesn't provide any return values and thus cannot signal an error if allocation of that temporary buffer has failed. Convert the function to swap via a temporary buffer allocated on the stack. Like this, it can `memcpy` contents of both elements in small batches without requiring a heap allocation. The buffer size has been chosen such that in most cases, a single iteration of copying will suffice. Most importantly, it can fully contain `git_oid` structures and pointers. Add a bunch of tests for the `git__qsort_r` interface to verify nothing breaks. Furthermore, this removes the declaration of `git__insertsort_r` and makes it static as it is not used anywhere else.
Edward Thomson db6b8f7d 2019-05-21T14:15:58 strtol: cast error message length to int
Edward Thomson ad6f2153 2019-05-21T12:50:46 utf8: use size_t for length of buffer The `git__utf8_charlen` now takes `size_t` as the buffer length, since it contains the full length of the buffer at the current position. It now returns `-1` in all cases where utf8 codepoints are invalid, since callers only care about a valid length of a sequence of codepoints, or if the current position is not valid utf8.

Edward Thomson e6c6d3bb 2019-02-17T22:31:37 Remove `git_time_monotonic` `git_time_monotonic` was added so that non-native bindings like rugged could get high-resolution timing for benchmarking. However, this is outside the scope of libgit2 *and* rugged decided not to use this function in the first place. Google suggests that absolutely _nobody_ is using this function and we don't want to be in the benchmarking business. Remove the function.

Patrick Steinhardt 4209a512 2018-11-14T12:04:42 strntol: fix out-of-bounds reads when parsing numbers with leading sign When parsing a number, we accept a leading plus or minus sign to return a positive or negative number. When the parsed string has such a leading sign, we set up a flag indicating that the number is negative and advance the pointer to the next character in that string. This misses updating the number of bytes in the string, though, which is why the parser may later on do an out-of-bounds read. Fix the issue by correctly updating both the pointer and the number of remaining bytes. Furthermore, we need to check whether we actually have any bytes left after having advanced the pointer, as otherwise the auto-detection of the base may do an out-of-bonuds access. Add a test that detects the out-of-bound read. Note that this is not actually security critical. While there are a lot of places where the function is called, all of these places are guarded or irrelevant: - commit list: this operates on objects from the ODB, which are always NUL terminated any may thus not trigger the off-by-one OOB read. - config: the configuration is NUL terminated. - curl stream: user input is being parsed that is always NUL terminated - index: the index is read via `git_futils_readbuffer`, which always NUL terminates it. - loose objects: used to parse the length from the object's header. As we check previously that the buffer contains a NUL byte, this is safe. - rebase: this parses numbers from the rebase instruction sheet. As the rebase code uses `git_futils_readbuffer`, the buffer is always NUL terminated. - revparse: this parses a user provided buffer that is NUL terminated. - signature: this parser the header information of objects. As objects read from the ODB are always NUL terminated, this is a non-issue. The constructor `git_signature_from_buffer` does not accept a length parameter for the buffer, so the buffer needs to be NUL terminated, as well. - smart transport: the buffer that is parsed is NUL terminated - tree cache: this parses the tree cache from the index extension. The index itself is read via `git_futils_readbuffer`, which always NUL terminates it. - winhttp transport: user input is being parsed that is always NUL terminated
Patrick Steinhardt 50d09407 2018-10-29T18:05:27 strntol: fix detection and skipping of base prefixes The `git__strntol` family of functions has the ability to auto-detect a number's base if the string has either the common '0x' prefix for hexadecimal numbers or '0' prefix for octal numbers. The detection of such prefixes and following handling has two major issues though that are being fixed in one go now. - We do not do any bounds checking previous to verifying the '0x' base. While we do verify that there is at least one digit available previously, we fail to verify that there are two digits available and thus may do an out-of-bounds read when parsing this two-character-prefix. - When skipping the prefix of such numbers, we only update the pointer length without also updating the number of remaining bytes. Thus if we try to parse a number '0x1' of total length 3, we will first skip the first two bytes and then try to read 3 bytes starting at '1'. Fix both issues by disentangling the logic. Instead of doing the detection and skipping of such prefixes in one go, we will now first try to detect the base while also honoring how many bytes are left. Only if we have a valid base that is either 8 or 16 and have one of the known prefixes, we will now advance the pointer and update the remaining bytes in one step. Add some tests that verify that no out-of-bounds parsing happens and that autodetection works as advertised.
Patrick Steinhardt 41863a00 2018-10-29T17:19:58 strntol: fix out-of-bounds read when skipping leading spaces The `git__strntol` family of functions accepts leading spaces and will simply skip them. The skipping will not honor the provided buffer's length, though, which may lead it to read outside of the provided buffer's bounds if it is not a simple NUL-terminated string. Furthermore, if leading space is trimmed, the function will further advance the pointer but not update the number of remaining bytes, which may also lead to out-of-bounds reads. Fix the issue by properly paying attention to the buffer length and updating it when stripping leading whitespace characters. Add a test that verifies that we won't read past the provided buffer length.

Patrick Steinhardt 83e8a6b3 2018-10-18T16:08:46 util: provide `git__memmem` function Unfortunately, neither the `memmem` nor the `strnstr` functions are part of any C standard but are merely extensions of C that are implemented by e.g. glibc. Thus, there is no standardized way to search for a string in a block of memory with a limited size, and using `strstr` is to be considered unsafe in case where the buffer has not been sanitized. In fact, there are some uses of `strstr` in exactly that unsafe way in our codebase. Provide a new function `git__memmem` that implements the `memmem` semantics. That is in a given haystack of `n` bytes, search for the occurrence of a byte sequence of `m` bytes and return a pointer to the first occurrence. The implementation chosen is the "Not So Naive" algorithm from [1]. It was chosen as the implementation is comparably simple while still being reasonably efficient in most cases. Preprocessing happens in constant time and space, searching has a time complexity of O(n*m) with a slightly sub-linear average case. [1]: http://www-igm.univ-mlv.fr/~lecroq/string/
Patrick Steinhardt ea19efc1 2018-10-18T15:08:56 util: fix out of bounds read in error message When an integer that is parsed with `git__strntol32` is too big to fit into an int32, we will generate an error message that includes the actual string that failed to parse. This does not acknowledge the fact that the string may either not be NUL terminated or alternative include additional characters after the number that is to be parsed. We may thus end up printing characters into the buffer that aren't the number or, worse, read out of bounds. Fix the issue by utilizing the `endptr` that was set by `git__strntol64`. This pointer is guaranteed to be set to the first character following the number, and we can thus use it to compute the width of the number that shall be printed. Create a test to verify that we correctly truncate the number.
Patrick Steinhardt b09c1c7b 2018-10-18T14:37:55 util: avoid signed integer overflows in `git__strntol64` While `git__strntol64` tries to detect integer overflows when doing the necessary arithmetics to come up with the final result, it does the detection only after the fact. This check thus relies on undefined behavior of signed integer overflows. Fix this by instead checking up-front whether the multiplications or additions will overflow. Note that a detected overflow will not cause us to abort parsing the current sequence of digits. In the case of an overflow, previous behavior was to still set up the end pointer correctly to point to the first character immediately after the currently parsed number. We do not want to change this now as code may rely on the end pointer being set up correctly even if the parsed number is too big to be represented as 64 bit integer.
Patrick Steinhardt 8d7fa88a 2018-10-18T12:04:07 util: remove `git__strtol32` The function `git__strtol32` can easily be misused when untrusted data is passed to it that may not have been sanitized with trailing `NUL` bytes. As all usages of this function have now been removed, we can remove this function altogether to avoid future misuse of it.
Patrick Steinhardt 68deb2cc 2018-10-18T11:37:10 util: remove unsafe `git__strtol64` function The function `git__strtol64` does not take a maximum buffer length as parameter. This has led to some unsafe usages of this function, and as such we may consider it as being unsafe to use. As we have now eradicated all usages of this function, let's remove it completely to avoid future misuse.

Module taken from 4f252abea5f1d17c60f6ff115c9c44cc0b6f1df6, which I've checked against CMake 2.8.11.
Stan Hu 9d83a2b0 2018-02-22T22:55:50 Sanitize the hunk header to ensure it contains UTF-8 valid data The diff driver truncates the hunk header text to 80 bytes, which can truncate 4-byte Unicode characters and introduce garbage characters in the diff output. This change sanitizes the hunk header before it is displayed. This mirrors the test in git: https://github.com/git/git/blob/master/t/t4025-hunk-header.sh Closes https://github.com/libgit2/rugged/issues/716
Patrick Steinhardt fbe52fa3 2018-03-29T10:18:51 util: fix missing headers for MinGW environments There are multiple references to undefined functions in the Microsoft builds. Add headers to make them known.
Patrick Steinhardt 92324d84 2018-02-16T11:28:53 util: clean up header includes While "util.h" declares the macro `git__tolower`, which simply resorts to tolower(3P) on Unix-like systems, the <ctype.h> header is only being included in "util.c". Thus, anybody who has included "util.h" without having <ctype.h> included will fail to compile as soon as the macro is in use. Furthermore, we can clean up additional includes in "util.c" and simply replace them with an include for "common.h".
Patrick Steinhardt 06b8a40f 2018-02-16T11:29:46 Explicitly mark fallthrough cases with comments A lot of compilers nowadays generate warnings when there are cases in a switch statement which implicitly fall through to the next case. To avoid this warning, the last line in the case that is falling through can have a comment matching a regular expression, where one possible comment body would be `/* fall through */`. An alternative to the comment would be an explicit attribute like e.g. `[[clang::fallthrough]` or `__attribute__ ((fallthrough))`. But GCC only introduced support for such an attribute recently with GCC 7. Thus, and also because the fallthrough comment is supported by most compilers, we settle for using comments instead. One shortcoming of that method is that compilers are very strict about that. Most interestingly, that comment _really_ has to be the last line. In case a closing brace follows the comment, the heuristic will fail.
Edward Thomson 86219f40 2017-11-30T15:40:13 util: introduce `git__prefixncmp` and consolidate implementations Introduce `git_prefixncmp` that will search up to the first `n` characters of a string to see if it is prefixed by another string. This is useful for examining if a non-null terminated character array is prefixed by a particular substring. Consolidate the various implementations of `git__prefixcmp` around a single core implementation and add some test cases to validate its behavior.
Patrick Steinhardt 0c7f49dd 2017-06-30T13:39:01 Make sure to always include "common.h" first Next to including several files, our "common.h" header also declares various macros which are then used throughout the project. As such, we have to make sure to always include this file first in all implementation files. Otherwise, we might encounter problems or even silent behavioural differences due to macros or defines not being defined as they should be. So in fact, our header and implementation files should make sure to always include "common.h" first. This commit does so by establishing a common include pattern. Header files inside of "src" will now always include "common.h" as its first other file, separated by a newline from all the other includes to make it stand out as special. There are two cases for the implementation files. If they do have a matching header file, they will always include this one first, leading to "common.h" being transitively included as first file. If they do not have a matching header file, they instead include "common.h" as first file themselves. This fixes the outlined problems and will become our standard practice for header and source files inside of the "src/" from now on.

Edward Thomson 75a4636f 2015-05-29T16:56:38 git__tolower: a tolower() that isn't dumb Some brain damaged tolower() implementations appear to want to take the locale into account, and this may require taking some insanely aggressive lock on the locale and slowing down what should be the most trivial of trivial calls for people who just want to downcase ASCII.
Edward Thomson 006548da 2015-05-29T16:07:51 git__strcasecmp: treat input bytes as unsigned Treat input bytes as unsigned before doing arithmetic on them, lest we look at some non-ASCII byte (like a UTF-8 character) as a negative value and perform the comparison incorrectly.

Edward Thomson a64119e3 2014-11-25T18:13:00 checkout: disallow bad paths on win32 Disallow: 1. paths with trailing dot 2. paths with trailing space 3. paths with trailing colon 4. paths that are 8.3 short names of .git folders ("GIT~1") 5. paths that are reserved path names (COM1, LPT1, etc). 6. paths with reserved DOS characters (colons, asterisks, etc) These paths would (without \\?\ syntax) be elided to other paths - for example, ".git." would be written as ".git". As a result, writing these paths literally (using \\?\ syntax) makes them hard to operate with from the shell, Windows Explorer or other tools. Disallow these.

As part of that, some of the special cases that arose with the externally used git_buffer were blended into the git_buf, such as being careful about git_buf objects that may have a NULL ptr and allowing for bufs with a valid ptr and size but zero asize as a way of referring to externally owned data.

Russell Belfer 41954a49 2013-03-18T14:19:35 Switch search paths to classic delimited strings This switches the APIs for setting and getting the global/system search paths from using git_strarray to using a simple string with GIT_PATH_LIST_SEPARATOR delimited paths, just as the environment PATH variable would contain. This makes it simpler to get and set the value. I also added code to expand "$PATH" when setting a new value to embed the old value of the path. This means that I no longer require separate actions to PREPEND to the value.
Russell Belfer 5540d947 2013-03-15T16:39:00 Implement global/system file search paths The goal of this work is to expose the search logic for "global", "system", and "xdg" files through the git_libgit2_opts() interface. Behind the scenes, I changed the logic for finding files to have a notion of a git_strarray that represents a search path and to store a separate search path for each of the three tiers of config file. For each tier, I implemented a function to initialize it to default values (generally based on environment variables), and then general interfaces to get it, set it, reset it, and prepend new directories to it. Next, I exposed these interfaces through the git_libgit2_opts interface, reusing the GIT_CONFIG_LEVEL_SYSTEM, etc., constants for the user to control which search path they were modifying. There are alternative designs for the opts interface / argument ordering, so I'm putting this phase out for discussion. Additionally, I ended up doing a little bit of clean up regarding attr.h and attr_file.h, adding a new attrcache.h so the other two files wouldn't have to be included in so many places.

Russell Belfer e40f1c2d 2013-03-08T16:39:57 Make tree iterator handle icase equivalence There is a serious bug in the previous tree iterator implementation. If case insensitivity resulted in member elements being equivalent to one another, and those member elements were trees, then the children of the colliding elements would be processed in sequence instead of in a single flattened list. This meant that the tree iterator was not truly acting like a case-insensitive list. This completely reworks the tree iterator to manage lists with case insensitive equivalence classes and advance through the items in a unified manner in a single sorted frame. It is possible that at a future date we might want to update this to separate the case insensitive and case sensitive tree iterators so that the case sensitive one could be a minimal amount of code and the insensitive one would always know what it needed to do without checking flags. But there would be so much shared code between the two, that I'm not sure it that's a win. For now, this gets what we need. More tests are needed, though.

This makes it impossible to implement sorted lists where the sort order depends on external data (e.g. building a secondary sort order for the entries in a tree). This commit adds git__bsearch_r and git__tsort_r versions that pass a third parameter to the cmp function of a user payload.

Russell Belfer 16248ee2 2012-11-21T11:03:07 Fix up some missing consts in tree & index This fixes some missed places where we can apply const-ness to various public APIs. There are still some index and tree APIs that cannot take const pointers because we sort our `git_vectors` lazily and so we can't reliably bsearch the index and tree content without applying a `git_vector_sort()` first. This also fixes some missed places where size_t can be used and where const can be applied to a couple internal functions.
Russell Belfer a277345e 2012-11-14T22:37:13 Create internal strcmp variants for function ptrs Using the builtin strcmp and strcasecmp as function pointers is problematic on win32. This adds internal implementations and divorces us from the platform linkage.

Adam Roben 8e60c712 2012-06-07T09:50:19 Fix git_status_file for files that start with a character > 0x7f git_status_file would always return GIT_ENOTFOUND for these files. The underlying bug was that git__strcmp_cb, which is used by git_path_with_stat_cmp to sort entries in the working directory, compares strings based on unsigned chars (this is confirmed by the strcmp(3) manpage), while git__prefixcmp, which is used by workdir_iterator__entry_cmp to search for a path in the working directory, compares strings based on char. So the sort puts this path at the end of the list, while the search expects it to be at the beginning. The fix was simply to make git__prefixcmp compare using unsigned chars, just like strcmp(3). The rest of the change is just adding/updating tests.

Russell Belfer 44ef8b1b 2012-04-13T13:00:10 Fix warnings on 64-bit windows builds This fixes all the warnings on win64 except those in deps, which come from the regex code.
Russell Belfer 14a513e0 2012-04-13T15:00:29 Add support for pathspec to diff and status This adds preliminary support for pathspecs to diff and status. The implementation is not very optimized (it still looks at every single file and evaluated the the pathspec match against them), but it works.
Russell Belfer 7c7ff7d1 2012-03-19T16:10:11 Migrate index, oid, and utils to new errors This includes a few cleanups that came up while converting these files. This commit introduces a could new git error classes, including the catchall class: GITERR_INVALID which I'm using as the class for invalid and out of range values which are detected at too low a level of library to use a higher level classification. For example, an overflow error in parsing an integer or a bad letter in parsing an OID string would generate an error in this class.
Russell Belfer 0d0fa7c3 2012-03-16T15:56:01 Convert attr, ignore, mwindow, status to new errors Also cleaned up some previously converted code that still had little things to polish.
Russell Belfer ae9e29fd 2012-03-06T16:14:31 Migrating diff to new error handling Ended up migrating a bunch of upstream functions as well including vector, attr_file, and odb in order to get this to work right.
