Bug#953291: linux-image-amd64: udp SO_REUSEPORT broken (fix in 4.19.75)
Package: linux-image-amd64
Version: 4.19+105+deb10u1~bpo9+1
Severity: normal
Tags: upstream
Dear Maintainer,
Since kernel 4.5, SO_REUSEPORT was somewhat broken for UDP when [1] landed. The
fix for this was backported to the 4.19 series in 4.19.75 [2]. However, both
kernels available on Debian oldstable (4.9.189 and 4.19.67) are affected by the
problem. It would be great if the backports oldstable kernel could be upgraded
to 4.19.75 or later (like what was done for the stable kernel) so that a fix is
available in oldstable.
