            Bug ID: 215594
           Summary: Unable to transfer big files to Nokia N9 and Jolla
                    phone
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.16-rc1
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Bluetooth
          Assignee: linux-bluetooth@vger.kernel.org
          Reporter: pmenzel+bugzilla.kernel.org@molgen.mpg.de
        Regression: No

Created attachment 300440
  --> https://bugzilla.kernel.org/attachment.cgi?id=300440&action=edit
Output of `btmon --write /dev/shm/btmon-trace.log`

Report:
https://lore.kernel.org/linux-bluetooth/def03073-3fab-3b34-6ffc-702bb1b3758f@leemhuis.info/T/#m04445e920610d42a9510d0f6d97afa5376e4a3ca

Created Bugzilla issue to upload log files.

Unfortunately, I do not know, how to capture `obexd` logs. `obexd -d` did not
print any messages to the terminal. `obexctl --monitor` also did not get it
more verbose.

So the transfer apparently didn't even start, with what system are you traying
to communicate to?

Just to also document it here, commit 81be03e026dc (Bluetooth: RFCOMM: Replace
use of memcpy_from_msg with bt_skb_sendmmsg) introduced that regression, and
reverting this fixes the issue.

I tested with latest BlueZ(HEAD:
https://git.kernel.org/pub/scm/bluetooth/bluez.git/commit/?id=002c0c9eda0052a834ddd4b63026f534b7d52f14)
without reverting the commits in
#3(https://bugzilla.kernel.org/show_bug.cgi?id=215594#c3) and RFCOMM worked
fine.
I tested both Windows 10 and MAC OS and was able to send and receive the files.

Please try it with the latest BlueZ and see if it makes any difference.

Thank you for looking into this. Did you test with MeeGo/Harmattan or Sailfish
OS?

Also, it wouldn’t make a difference, as Linux’ no-regression-policy requires,
that the everything keeps working with the existing user space.

(As written in the mailing list thread, with the Android phone Galaly M32 the
file transfer succeeded.)

How about getting some logs from obexd then? Stop obexd.service and start with
obexd/src/obexd -dn
