Hello,

TL;RD: if you are a bridge operator please update obfs4proxy to a version>=0.0.12.

Thanks, done.

Worth noting I had to adjust (on Debian) /etc/apparmor.d/abstractions/tor to contain:

/sys/kernel/mm/transparent_hugepage/hpage_pmd_size r,

To prevent the error:

apparmor="DENIED" operation="open" profile="system_tor" name="/sys/kernel/mm/transparent_hugepage/hpage_pmd_size

per [1].

And be sure to setcap the obfs4proxy binary again if running on a port<1024, as well as restart Tor after updating.

Cheers.
