This regression was introduced in 74703a1e4dfc (submodule: rewrite `module_list` shell function in C, 2015-09-02), as we changed the order of checking in new module listing to first check whether it is a gitlin before feeding it to match_pathspec(). It used to be that a pathspec that does not match any path were diagnosed as an error, but the new code complains for a pathspec that does not match any submodule path. Arguably the new behaviour may give us a better diagnosis, but that is inconsistent with the suggestion "deinit" gives, and also this was an unintended accident. The new behaviour hopefully can be redesigned and implemented better in future releases, but for now, switch these two checks to restore the same behavior as before. In an empty repository, giving the pathspec '.' will still get the same "did not match" error, but that is the same bug we had before 1.7.0.

2016-02-25nth_packed_object_offset: bounds-check extended offsetLibravatar Jeff King1-0/+1
If a pack .idx file has a corrupted offset for an object, we may try to access an offset in the .idx or .pack file that is larger than the file's size. For the .pack case, we have use_pack() to protect us, which realizes the access is out of bounds. But if the corrupted value asks us to look in the .idx file's secondary 64-bit offset table, we blindly add it to the mmap'd index data and access arbitrary memory. We can fix this with a simple bounds-check compared to the size we found when we opened the .idx file. Note that there's similar code in index-pack that is triggered only during "index-pack --verify". To support both, we pull the bounds-check into a separate function, which dies when it sees a corrupted file. It would be nice if we could return an error, so that the pack code could try to find a good copy of the object elsewhere. Currently nth_packed_object_offset doesn't have any way to return an error, but it could probably use "0" as a sentinel value (since no object can start there). This is the minimal fix, and we can improve the resilience later on top. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-02-25push: remove "push.default is unset" warning messageLibravatar Matthieu Moy1-34/+0
The warning was important before the 2.0 transition, and remained important for a while after, so that new users get push.default explicitly in their configuration and do not experience inconsistent behavior if they ever used an older version of Git. The warning has been there since version 1.8.0 (Oct 2012), hence we can expect the vast majority of current Git users to have been exposed to it, and most of them have already set push.default explicitly. The switch from 'matching' to 'simple' was planned for 2.0 (May 2014), but actually happened only for 2.3 (Feb 2015). Today, the warning is mostly seen by beginners, who have not set their push.default configuration (yet). For many of them, the warning is confusing because it talks about concepts that they have not learned and asks them a choice that they are not able to make yet. See for example http://stackoverflow.com/questions/13148066/warning-push-default-is-unset-its-implicit-value-is-changing-in-git-2-0 (1260 votes for the question, 1824 for the answer as of writing) Remove the warning completely to avoid disturbing beginners. People who still occasionally use an older version of Git will be exposed to the warning through this old version. Eventually, versions of Git without the warning will be deployed enough and tutorials will not need to advise setting push.default anymore.

The "name_path" API was an attempt to reduce the need to construct the full path out of a series of path components while walking a tree hierarchy, but over time made less efficient because the path needs to be flattened, e.g. to be compared with another path that is already flat.

2016-02-22fetch-pack: simplify add_sought_entryLibravatar Jeff King1-18/+9
We have two variants of this function, one that takes a string and one that takes a ptr/len combo. But we only call the latter with the length of a NUL-terminated string, so our first simplification is to drop it in favor of the string variant. Since we know we have a string, we can also replace the manual memory computation with a call to alloc_ref(). Furthermore, we can rely on get_oid_hex() to complain if it hits the end of the string. That means we can simplify the check for "<sha1> <ref>" versus just "<ref>". Rather than manage the ptr/len pair, we can just bump the start of our string forward. The original code over-allocated based on the original "namelen" (which wasn't _wrong_, but was simply wasteful and confusing).

2016-02-22use st_add and st_mult for allocation size computationLibravatar Jeff King7-9/+9
If our size computation overflows size_t, we may allocate a much smaller buffer than we expected and overflow it. It's probably impossible to trigger an overflow in most of these sites in practice, but it is easy enough convert their additions and multiplications into overflow-checking variants. This may be fixing real bugs, and it makes auditing the code easier. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-02-22convert trivial cases to FLEX_ARRAY macrosLibravatar Jeff King4-18/+11
Using FLEX_ARRAY macros reduces the amount of manual computation size we have to do. It also ensures we don't overflow size_t, and it makes sure we write the same number of bytes that we allocated. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-02-22use xmallocz to avoid size arithmeticLibravatar Jeff King3-3/+3
We frequently allocate strings as xmalloc(len + 1), where the extra 1 is for the NUL terminator. This can be done more simply with xmallocz, which also checks for integer overflow. There's no case where switching xmalloc(n+1) to xmallocz(n) is wrong; the result is the same length, and malloc made no guarantees about what was in the buffer anyway. But in some cases, we can stop manually placing NUL at the end of the allocated buffer. But that's only safe if it's clear that the contents will always fill the buffer. In each case where this patch does so, I manually examined the control flow, and I tried to err on the side of caution.

2016-02-22convert trivial cases to ALLOC_ARRAYLibravatar Jeff King9-14/+16
Each of these cases can be converted to use ALLOC_ARRAY or REALLOC_ARRAY, which has two advantages: 1. It automatically checks the array-size multiplication for overflow. 2. It always uses sizeof(*array) for the element-size, so that it can never go out of sync with the declared type of the array.

2016-02-22convert manual allocations to argv_arrayLibravatar Jeff King3-35/+13
There are many manual argv allocations that predate the argv_array API. Switching to that API brings a few advantages: 1. We no longer have to manually compute the correct final array size (so it's one less thing we can screw up). 2. In many cases we had to make a separate pass to count, then allocate, then fill in the array. Now we can do it in one pass, making the code shorter and easier to follow. 3. argv_array handles memory ownership for us, making it more obvious when things should be free()d and and when not. Most of these cases are pretty straightforward. In some, we switch from "run_command_v" to "run_command" which lets us directly use the argv_array embedded in "struct child_process".

Dying is the default for a lot of internal functions when failures occur and is in this case the right thing to do for most callers as otherwise we might run into inconsistent repositories without noticing.

2016-02-19reflog_expire_cfg: NUL-terminate pattern fieldLibravatar Jeff King1-5/+3
You can tweak the reflog expiration for a particular subset of refs by configuring gc.foo.reflogexpire. We keep a linked list of reflog_expire_cfg structs, each of which holds the pattern and a "len" field for the length of the pattern. The pattern itself is _not_ NUL-terminated. However, we feed the pattern directly to wildmatch(), which expects a NUL-terminated string, meaning it may keep reading random junk after our struct. We can fix this by allocating an extra byte for the NUL (which is already zero because we use xcalloc). Let's also drop the misleading "len" field, which is no longer necessary. The existing use of "len" can be converted to use strncmp(). Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-02-16remote: use remote_is_configured() for add and renameLibravatar Thomas Gummerer1-5/+2
Both remote add and remote rename use a slightly different hand-rolled check if the remote exits. The hand-rolled check may have some subtle cases in which it might fail to detect when a remote already exists. One such case was fixed in fb86e32 ("git remote: allow adding remotes agreeing with url.<...>.insteadOf"). Another case is when a remote is configured as follows: [remote "foo"] vcs = bar If we try to run `git remote add foo bar` with the above remote configuration, git segfaults. This change fixes it. In addition, git remote rename $existing foo with the configuration for foo as above silently succeeds, even though foo already exists, modifying its configuration. With this patch it fails with "remote foo already exists".
