Package: src:linux
Version: 3.16.56-1
Severity: normal
Dear Maintainer,
With latest Debian Jessie Linux kernel (3.16.56-1) version,
my SCTP application, which uses an IPv6 socket to get IPv4 or IPv6 messages,
can retrieve anymore IPv4 addresses from peers, using sctp_getpaddrs() function.
I've identified the impacting patch :r
sctp: Fixup v4mapped behaviour to comply with Sock API
I've rebuilt a kernel with this patch reverted, and my application works
well with
I retrieve IPv4 peer addresses in a IPv6-mapped format, like :
0x00: 0A 00 A5 B8 C0 A8 FE B2 00 00 00 00 ............
0x0C: 00 00 00 00 00 00 FF FF C0 A8 FE B2 ............
0x18: 30 3B C0 1F 0;..
which means : ::ffff:192.168.254.178%532691760 -> 192.168.254.178
But with the latest Jessie kernel, i get :
0x00: 0A 00 A5 B8 00 00 00 00 00 00 00 00 ............
0x0C: 00 00 00 00 00 00 FF FF 00 00 00 00 ............
0x18: 00 00 00 00 ....
which translates to : ::ffff:0.0.0.0
I've stated the same bug with latest Debian Wheezy kernel
(linux-image-3.2.0-6-amd64 package, 3.2.101-1 version) :
I don't know if i should add a separate bug report ?
With regards,
Fred.
