Björn Töpel 0e2b048ffe ixgbe: avoid premature Rx buffer reuse ... [ Upstream commit a06316dc87 ] The page recycle code, incorrectly, relied on that a page fragment could not be freed inside xdp_do_redirect(). This assumption leads to that page fragments that are used by the stack/XDP redirect can be reused and overwritten. To avoid this, store the page count prior invoking xdp_do_redirect(). Fixes: 6453073987 ("ixgbe: add initial support for xdp redirect") Reported-and-analyzed-by: Li RongQing <lirongqing@baidu.com> Signed-off-by: Björn Töpel <bjorn.topel@intel.com> Tested-by: Sandeep Penigalapati <sandeep.penigalapati@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> Signed-off-by: Sasha Levin <sashal@kernel.org>		2020-12-30 11:50:56 +01:00
