The split_cmdline() function introduced in [1] returns an "int". If it's negative it signifies an error. The option parsing in [2] didn't account for this, and assigned the value directly to the "size_t xopts_nr". We'd then attempt to loop over all of these elements, and access uninitialized memory. There's a few things that use this for option parsing, but one way to trigger it is with a bad value to "-X <strategy-option>", e.g: git rebase -X"bad argument\"" In another context this might be a security issue, but in this case someone who's already able to inject arguments directly to our commands would be past other defenses, making this potential escalation a moot point. As the example above & test case shows the error reporting leaves something to be desired. The function will loop over the whitespace-split values, but when it encounters an error we'll only report the first element, which is OK, not the second "argument\"" whose quote is unbalanced. This is an inherent limitation of the current API, and the issue affects other API users. Let's not attempt to fix that now. If and when that happens these tests will need to be adjusted to assert the new output. 1. 2b11e3170e9 (If you have a config containing something like this:, 2006-06-05) 2. ca6c6b45dd9 (sequencer (rebase -i): respect strategy/strategy_opts settings, 2017-01-02) Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
Git - fast, scalable, distributed revision control system
Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see
Documentation/giteveryday.txt for a useful minimum set of commands, and
Documentation/git-<commandname>.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with man gittutorial or git help tutorial, and the
documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt
(man gitcvs-migration or git help cvs-migration if git is
installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission and Documentation/CodingGuidelines).
Those wishing to help with error message, usage and informational message
string translations (localization l10) should see po/README.md
(a po file is a Portable Object file that holds the translations).
To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org (not the Git list). The mailing list archives are available at https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):
- random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
- stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
- "global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
- "goddamn idiotic truckload of sh*t": when it breaks
