Well behaved and non-hostile frontends will not be -penalised. - -As well as making the existing checks for such errors fatal also add a -new check that ensures that there isn't an insane number of requests -on the ring (i.e. more than would fit in the ring). If the ring -contains garbage then previously is was possible to loop over this -insane number, getting an error each time and therefore not generating -any more pending requests and therefore not exiting the loop in -xen_netbk_tx_build_gops for an externded period. - -Also turn various netdev_dbg calls which no precipitate a fatal error -into netdev_err, they are rate limited because the device is shutdown -afterwards. - -This fixes at least one known DoS/softlockup of the backend domain. - -Signed-off-by: Ian Campbell <ian.campbell@citrix.com> -Reviewed-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> -Acked-by: Jan Beulich <JBeulich@suse.com> ---- - drivers/net/xen-netback/common.h | 3 ++ - drivers/net/xen-netback/interface.c | 23 ++++++++----- - drivers/net/xen-netback/netback.c | 63 +++++++++++++++++++++++++--------- - 3 files changed, 63 insertions(+), 26 deletions(-) - -diff --git a/drivers/net/xen-netback/common.h b/drivers/net/xen-netback/common.h -index 94b79c3..9d7f172 100644 ---- a/drivers/net/xen-netback/common.h -+++ b/drivers/net/xen-netback/common.h -@@ -151,6 +151,9 @@ void xen_netbk_queue_tx_skb(struct xenvif *vif, struct sk_buff *skb);
