Subject: [PATCH v3 0/3] Directory traversal bugs
Date: Tue, 17 Dec 2019 08:33:03 +0000 [thread overview]
Message-ID: <pull.676.v3.git.git.1576571586.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.676.v2.git.git.1576008027.gitgitgadget@gmail.com>
This series documents multiple fill_directory() bugs, and fixes the one that
is new to 2.24.0 coming from en/clean-nested-with-ignored-topic, the rest
having been around in versions of git going back up to a decade.
Changes since v2:
* gutted the series of most the fixes, dropping the patch count from 8 to
3, due to incompatibility with git-for-windows (which interestingly has a
different compat/win32/dirent.h than git.git does). The only bugs
reported by a user are fixed by patch 3, and fixing the remaining bugs
(which I found while investigating the one fixed bug) would require a
major refactor that I don't have the time for currently.
Elijah Newren (3):
t3011: demonstrate directory traversal failures
dir: remove stray quote character in comment
dir: exit before wildcard fall-through if there is no wildcard

of the en/clean-nested-with-ignored-topic); the other 5 also failed
under git-2.23.0 and earlier.
+ The old failing tests can be traced down to the common prefix
+ optimization in dir.c handling paths differently than
+ read_directory_recursive() and treat_path() would, due to incomplete
+ duplication of logic into treat_leading_path() and having that
+ function call treat_one_path() rather than treat_path(). Fixing
+ that problem would require restructuring treat_path() and its full
+ call hierarchy to stop taking a dirent; see
+ https://lore.kernel.org/git/xmqqzhfshsk2.fsf@gitster-ct.c.googlers.com/
+ and the thread surrounding it for details.
+
+ For now, simply document the breakages.
