From: Jesse Gross <jesse@...nel.org> Date: Wed, 20 Jan 2016 17:59:49 -0800 > GRO is currently not aware of tunnel metadata generated by lightweight > tunnels and stored in the dst. This leads to two possible problems: > * Incorrectly merging two frames that have different metadata. > * Leaking of allocated metadata from merged frames. > > This avoids those problems by comparing the tunnel information before > merging, similar to how we handle other metadata (such as vlan tags), > and releasing any state when we are done. > > Reported-by: John <john.phillips5@....com> > Fixes: 2e15ea39 ("ip_gre: Add support to collect tunnel metadata.") > Signed-off-by: Jesse Gross <jesse@...nel.org> > --- > v2: Remove branches to optimize for common case where there is no dst. Applied and queued up for -stable, thanks.
