With 8959555cee7e[1] ("setup_git_directory(): add an owner check for the top..")
git added an ownership check of the git directory and refuses to
run any git commands, even parsing the config file, if the git directory
is not owned by the current user. The "fatal: detected dubious ownership in repository"
is reported.
This fixes CVE-2022-24765[2], which allows to compromise user account. On a
multi-user system or e.g. on a shared file system, one user may create a "rogue"
git repository with e.g. core.fsmonitor set to an arbitrary command. Other user
may unwillingly execute this command by running e.g. git-diff or
git-status within the "rogue" git repository, which may be in one of the parent
directories. If e.g. PS1 is set to display information about a git
repository in CWD, as suggested in Git in Bash[3], the user do not need to run
any git command to trigger this, just entering some subdirectory under
this "rogue" git repository is enough, because the git command will be
started transparently through the script used in PS1. The core.fsmonitor
can be set to arbitrary command. It's purpose is to help git to identify changed files
and speed up the scanning for changed files.
rogue
├── .git # owned by user1
└── dir1 # owned by user2
├── dir2 # owned by user2
└── .git # owned by user2
user1 sets core.fsmonitor for git repository in rogue directory
$ git config --add core.fsmonitor "bash -c 'rm -rf \$HOME'"
user2 enters dir1 and runs e.g. git diff and triggers the core.fsmonitor command.
The ownership check may cause problems when running git commands in
ESP-IDF Docker container. For example user may run the container as
root, but the mounted project may be owned by a particular user.
In this case git will refuse to execute any git command within the
"/project" directory, because it's not owned by root. To overcome this,
git allows to set safe.directories, for which the ownership check is
skipped. The security check may be completely disabled by setting
safe.directories to "*". This solution was proposed in PR 12636[4], but
it would allow make it possible to exploit this vulnerability again.
This fix allows user to specify git's safe.directory in IDF_GIT_SAFE_DIR
environmental variable, which may be set during container startup.
The IDF_GIT_SAFE_DIR has same format as PATH and multiple directories can be
specified by using a ":" separator. To entirely disable this git security check
within the container, user may set IDF_GIT_SAFE_DIR='*'. This might be
heplfull in CI.

IDF_PYTHON_ENV_PATH is the path where the Python environment is created
and used. By default it is inside IDF_TOOLS_PATH. IDF_PYTHON_ENV_PATH
was exported by idf_tools.py but was not imported back. This fixes the
issue and ESP-IDF will honor the value of IDF_PYTHON_ENV_PATH.
Closes https://github.com/espressif/esp-idf/issues/10489
The Python dependency checker called from the export scripts and before
build remains offline, i.e. it will use the previously downloaded
constraint file but won't download a newer version.
Related to https://github.com/espressif/esp-idf/pull/9328
Constraint files can be disabled with environment variable as well which
is useful when one uses the install/export scripts instead of
idf_tools.py directly. This is option is useful for offline build as
well.

GDB now is standalone tool separated from toolchain due to frequent updates.
Added installation tests for the new tool.
Tests are changed because they were wrong, see explanation:
esp32 objdump:
40084290 <esp_crosscore_int_send_yield>:
......
/builds/espressif/esp-idf/components/esp_system/crosscore_int.c:145
4008429c: 000090 retw
With previous GDB backtrace was:
#0 0x4008429c in esp_crosscore_int_send_yield (core_id=0) at /builds/espressif/esp-idf/components/esp_system/crosscore_int.c:144
This commit fixes the backtrace with the right line number:
#0 0x4008429c in esp_crosscore_int_send_yield (core_id=0) at /builds/espressif/esp-idf/components/esp_system/crosscore_int.c:145
Other tests changes have the same cause of fixing.
Closes https://github.com/espressif/esp-idf/issues/6334
This moves all the documentation relating to using idf.py out of the build system documentation in order to declutter and more logically group the documentation.
It is now present in the tools page under IDF Frontend - idf.py.
Additionally there has been lots of rewriting and some minor fixes on the way.
