The following series adds support for exposing various connector features using
debugfs. The first patch refactors the sysfs connector add and remove functions
into generic functions to register and unregister connectors. The remaining
patches add an interface for each connector to debugfs and expose the force
connector attribute and allow the edid value to be overridden.
Thomas Wood (3):
drm: add register and unregister functions for connectors
drm/debugfs: add a "force" file per connector
drm/debugfs: add an "edid_override" file per connector

Introduce generic functions to register and unregister connectors. This
provides a common place to add and remove associated user space
interfaces.

That hits on "o" as strncmp("o", "on", 1) == 0. We really need a
"startswith()" macro in the kernel.. same below.

You need to cleanup connector->debugfs_entry here as you're not doing
that in drm_connector_add().

Please copy "ubuf" before accessing it.. that's a user-space buffer.

What? So if you write any invalid EDID, you reset it? That's wrong..
You should return an error in those cases.

> + (struct edid *) ubuf);

Please check the error-code of update_edid_property() before setting
override_edid. You should also return that code if it is an error.
Furthermore, you must force override_edid = false; before calling
update_edid_property, otherwise writing twice to this file will
discard the second write (because update_edid_property() will do
nothing as override_edid is already true).
Last but not least, you *must* do an overflow check here!

Maybe you want something like this (untested!):
char *buf;
struct edid *edid;
int ret;
buf = memdup_user(ubuf, len);
if (IS_ERR(buf))
return PTR_ERR(buf);
edid = buf;
connector->override_edid = false;
if (len == 5 && !strcmp(buf, "reset")) {
ret = drm_mode_connector_update_edid_property(connector, NULL);
} else if (len < EDID_LENGTH || EDID_LENGTH * (1 + edid->extensions) > len) {
ret = -EINVAL;
} else {
ret = drm_mode_connector_update_edid_property(connector,
(struct edid*)buf);
if (!ret)
connector->override_edid = true;
}
kfree(buf);
return ret ? : len;
Thanks

Add a file to debugfs for each connector to enable modification of the
"force" connector attribute. This allows connectors to be enabled or
disabled for testing and debugging purposes.
v2: Add stricter value checking and clean up debugfs_entry if file
creation fails in drm_debugfs_connector_add. (David Herrmann)

Add a file to debugfs for each connector to allow the EDID to be
overridden.
v2: Copy ubuf before accessing it and reject invalid length data. (David
Herrmann)
Ensure override_edid is reset when a new EDID value is written.
(David Herrmann)
Fix the debugfs file permissions. (David Herrmann)

Might be worth doing some minimal validation of the EDID (e.g., make
sure it has a valid header).

Actually we also have plans to abuse this for a bit of nasty EDID
injection to exercise our parser. So at most we should do just enough
checking to make sure the claimed edid length field agrees with the edid
itself (which we have), but beyond that any kind of garbage should be
allowed imo.
