Hi Clemens and Iwai-san,
I found a critical bug on ALSA IEC 61883-1/6 engine at error handling on process context. At packet queueing error or detection of invalid packet, user process can stall on local CPU with IRQ disabled. This bug was introduced at v3.5.
I wrote a fix but this can be applied down to v4.9.31, but it's unavailable for the former longterm versions. What can we do for them?
You can send a different patch for each stable kernel to stable ML once after the original patch gets merged to Linus tree.
I'm OK for the additional work, thanks.
After reviewing, would you please send this to linus as a part of fix for 4.12? Then I start to work for each of the longterms.
OK, will queue to for-linus later, but slipped from today's batch for 4.12-rc5. It'll be in 4.12-rc6 request once after testing in linux-next.
The patch isn't applicable, likely your MUA broke it. Could you resend via git-sendmail properly?
thanks,
Takashi
