8959555cee7 (setup_git_directory(): add an owner check for the top-level
directory, 2022-03-02), adds a function to check for ownership of
repositories using a directory that is representative of it, and ways to
add exempt a specific repository from said check if needed, but that
check didn't account for owership of the gitdir, or (when used) the
gitfile that points to that gitdir.
An attacker could create a git repository in a directory that they can
write into but that is owned by the victim to work around the fix that
was introduced with CVE-2022-24765 to potentially run code as the
victim.
An example that could result in privilege escalation to root in *NIX would
be to set a repository in a shared tmp directory by doing (for example):
$ git -C /tmp init
To avoid that, extend the ensure_valid_ownership function to be able to
check for all three paths.
This will have the side effect of tripling the number of stat() calls
when a repository is detected, but the effect is expected to be likely
minimal, as it is done only once during the directory walk in which Git
looks for a repository.
Additionally make sure to resolve the gitfile (if one was used) to find
the relevant gitdir for checking.
While at it change the message printed on failure so it is clear we are
referring to the repository by its worktree (or gitdir if it is bare) and
not to a specific directory.

In asciidoc's HTML output of the "gitrevisions" and "git-rev-parse"
documentation, the header:
The ... (three-dot) Symmetric Difference Notation
is rendered using "&8230;", a horizontal ellipsis. This is visually
ugly, but also hard to search for or cut-and-paste. We really mean three
ascii dots (0x2e) here, so let's make sure it renders as such.
The simplest way to do that is just escaping the leading dot, as the
instances in the rest of the section do. Arguably this should all be
converted to use backticks, which would let us drop the quoting here and
elsewhere (e.g., {carat}). But that does change the rendering slightly.
So let's fix the bug first, and we can decide on migrating the whole
section separately.
Note that this produces an empty doc-diff of the manpages. Curiously,
asciidoc produces the same ellipsis entity in the XML file, but docbook
then converts it back into three literal dots for the roff output! So
the roff manpages have been correct all along (which may be a reason
nobody noticed this until now).

Since 8d92fb2927 (dir: replace exponential algorithm with a linear one,
2020-04-01) traversing into a repository's directory tree when the
traversal began outside the repository's standard location has failed
because the encountered repository was identified as a nested foreign
repository.
Prior to this commit, the failure to traverse into a repository's
default worktree location was observable from a user's perspective under
either of the following conditions (there may be others):
1) Set the `core.worktree` location to a parent directory of the
default worktree; or
2) Use the `--git_dir` option while the working directory is outside
the repository's default worktree location
Under either of these conditions, symptoms of the failure to traverse
into the repository's default worktree location include the inability to
add files to the index or get a list of untracked files via ls-files.
This commit adds a check to determine whether a nested repository that
is encountered in recursing a path is actually `the_repository`. If so,
we simply treat the directory as if it doesn't contain a nested
repository.
The commit includes test-cases to reduce the likelihood of future
regressions.

The many test_configured_prune tests in t5510-fetch.sh test many
combinations of --prune, --prune-tags, and using 'origin' or an explicit
URL. Some machinery was introduced in e1790f9245f (fetch tests: fetch
<url> <spec> as well as fetch [<remote>], 2018-02-09) to replace
'origin' with this explicit URL. This URL is a "file:///" URL for the
root of the $TRASH_DIRECTORY.
However, if the current build tree has an '@' symbol, the
replacement using perl fails. It drops the '@' as well as anything
else in that directory name. You can observe this locally by
cloning git.git into a "victim@03" directory and running the test
script.
As we are writing in Perl anyway, pass in the shell variables involved
to the script as arguments and perform necessary string transformations
inside it, instead of assuming that it is sufficient to enclose the
$remote_url variable inside a pair of single quotes.

With 31c8221a (mktree: validate entry type in input, 2009-05-14), we
called the sha1_object_info() API to obtain the type information, but
allowed the call to silently fail when the object was missing locally,
so that we can sanity-check the types opportunistically when the
object did exist.
The implementation is understandable because back then there was no
lazy/on-demand downloading of individual objects from the promisor
remotes that causes a long delay and materializes the object, hence
defeating the point of using "--missing". The design is hurting us
now.
We could bypass the opportunistic type/mode consistency check
altogether when "--missing" is given, but instead, use the
oid_object_info_extended() API and tell it that we are only interested
in objects that locally exist and are immediately available by passing
OBJECT_INFO_SKIP_FETCH_OBJECT bit to it. That way, we will still
retain the cheap and opportunistic sanity check for local objects.

Previous changes introduced a regression which will prevent root for
accessing repositories owned by thyself if using sudo because SUDO_UID
takes precedence.
Loosen that restriction by allowing root to access repositories owned
by both uid by default and without having to add a safe.directory
exception.
A previous workaround that was documented in the tests is no longer
needed so it has been removed together with its specially crafted
prerequisite.

Some config variables are combinations of multiple words, and we
typically write them in camelCase forms in manpage and translatable
strings. It's not easy to find mismatches for these camelCase config
variables during code reviews, but occasionally they are identified
during localization translations.
To check for mismatched config variables, I introduced a new feature
in the helper program for localization[^1]. The following mismatched
config variables have been identified by running the helper program,
such as "git-po-helper check-pot".
Lowercase in manpage should use camelCase:
* Documentation/config/http.txt: http.pinnedpubkey
Lowercase in translable strings should use camelCase:
* builtin/fast-import.c: pack.indexversion
* builtin/gc.c: gc.logexpiry
* builtin/index-pack.c: pack.indexversion
* builtin/pack-objects.c: pack.indexversion
* builtin/repack.c: pack.writebitmaps
* commit.c: i18n.commitencoding
* gpg-interface.c: user.signingkey
* http.c: http.postbuffer
* submodule-config.c: submodule.fetchjobs

The code added 0cc05b044f (usage.c: add a non-fatal bug() function to go
with BUG(), 2022-06-02) sets up two va_list variables: one to output to
stderr, and one to trace2. But the order of initialization is wrong:
va_list ap, cp;
va_copy(cp, ap);
va_start(ap, fmt);
We copy the contents of "ap" into "cp" before it is initialized, meaning
it is full of garbage. The two should be swapped.
However, there's another bug, noticed by Johannes Schindelin: we forget
to call va_end() for the copy. So instead of just fixing the copy's
initialization, let's do two separate start/end pairs. This is allowed
by the standard, and we don't need to use copy here since we have access
to the original varargs. Matching the pairs with the calls makes it more
obvious that everything is being done correctly.
Note that we do call bug_fl() in the tests, but it didn't trigger this
problem because our format string doesn't have any placeholders. So even
though we were passing a garbage va_list through the stack, nobody ever
needed to look at it. We can easily adjust one of the trace2 tests to
trigger this, both for bug() and for BUG(). The latter isn't broken, but
it's nice to exercise both a bit more. Without the fix in this patch
(but with the test change), the bug() case causes a segfault.
