Re: [PATCH net v2] net: qrtr: announce local services again once our HELLO is sent

[Filippo Falezza <effeffe99@gmail.com>]

Hello Joonhoe,

I ran into the same problem on a Motorola Moto G 5G Plus (SM7250),
which I'm bringing up on linux-next (next-20261021). Since the HELLO
gate went in, the name service's first announcement to the modem fails
with -EAGAIN on every boot, and so far I had been carrying a local
retry loop in ns.c to get rmtfs announced to it.

I dropped that loop, applied your v2 instead, and booted the phone
seven times in a row. The modem came up and registered on the network
on every boot, with rmtfs serving it, and the phone never reset.
"failed to announce new service" still shows up once for a remote
whose HELLO arrives before ours (one boot logged it for both the ADSP
and the modem, others once or not at all), and the modem carries on
normally afterwards, which matches the replay doing its job.

One thing I couldn't cover is a modem restart: on this phone it
resets the whole SoC with or without your patch, so that's a separate
problem here and says nothing about the patch.

I did the testing with the help of an AI coding assistant (Claude Code);
the results above are from the phone.
