[Bluez PATCH 1/3] Listen and process remote name resolving failure

[Archie Pusaka]

From: Archie Pusaka <apusaka@chromium.org>

When Remote Name Resolve ends with failure, record this occurrence and
prevent remote name resolving for the same device for some time.
Increase the time duration for subsequent failures.

Hi maintainers,

This is the patch series for remote name request as was discussed here.
https://patchwork.kernel.org/project/bluetooth/patch/20211028191805.1.I35b7f3a496f834de6b43a32f94b6160cb1467c94@changeid/
Please also review the corresponding kernel space change.

[Bluez PATCH 2/3] device: Save remote name request attempts into cache file

[Archie Pusaka]

From: Archie Pusaka <apusaka@chromium.org>

Since a peer device is potentially removed if not discovered for more
than 30 seconds, we would lost the remote name request activity when
the device is rediscovered. This could end up with a remote name
request much sooner than we intend it to be.

Therefore, put the RNR record into a cache file, so we can recover it
when the peer device is rediscovered.

[Bluez PATCH 3/3] doc: Add Name Resolve Fail flag in device found event

[Archie Pusaka]

From: Archie Pusaka <apusaka@chromium.org>

Userspace should use this new flag to decide whether to do the remote
name resolving or not, by sending Confirm Name MGMT command and set
the appropriate flag.

This patch also extends the Confirm Name command by allowing userspace
to send 0x02 to show it doesn't care about the peer devices names.

I am a bit worried about userspace sending a 0x02 for a kernel that doesn’t understand it. Do you think the kernel can make use of this “don’t care” information? Or should we just keep it to userspace to send 0x01 / 0x00 based on its policy.

I would do “Name Request Failed” here. Just to be a bit inline what the spec term is.

On the current kernel, 0x02 would be casted to True, and the kernel
would treat this as "name is known".
Indeed, this "don't care" information is of no use to the Kernel (at
least for now).

we do when we receive a Device Found event for a device which is
already discovered before.
