[PATCH 1/2] ice: Fix race conditions between virtchnl handling and VF ndo ops

by Jacob Keller

From: Brett Creeley <brett.creeley(a)intel.com> commit e6ba5273d4ede03d075d7a116b8edad1f6115f4d upstream. [I had to fix the cherry-pick manually as the patch added a line around some context that was missing.] The VF can be configured via the PF's ndo ops at the same time the PF is receiving/handling virtchnl messages. This has many issues, with one of them being the ndo op could be actively resetting a VF (i.e. resetting it to the default state and deleting/re-adding the VF's VSI) while a virtchnl message is being handled. The following error was seen because a VF ndo op was used to change a VF's trust setting while the VIRTCHNL_OP_CONFIG_VSI_QUEUES was ongoing: [35274.192484] ice 0000:88:00.0: Failed to set LAN Tx queue context, error: ICE_ERR_PARAM [35274.193074] ice 0000:88:00.0: VF 0 failed opcode 6, retval: -5 [35274.193640] iavf 0000:88:01.0: PF returned error -5 (IAVF_ERR_PARAM) to our request 6 Fix this by making sure the virtchnl handling and VF ndo ops that trigger VF resets cannot run concurrently. This is done by adding a struct mutex cfg_lock to each VF structure. For VF ndo ops, the mutex will be locked around the critical operations and VFR. Since the ndo ops will trigger a VFR, the virtchnl thread will use mutex_trylock(). This is done because if any other thread (i.e. VF ndo op) has the mutex, then that means the current VF message being handled is no longer valid, so just ignore it. This issue can be seen using the following commands: for i in {0..50}; do rmmod ice modprobe ice sleep 1 echo 1 > /sys/class/net/ens785f0/device/sriov_numvfs echo 1 > /sys/class/net/ens785f1/device/sriov_numvfs ip link set ens785f1 vf 0 trust on ip link set ens785f0 vf 0 trust on sleep 2 echo 0 > /sys/class/net/ens785f0/device/sriov_numvfs echo 0 > /sys/class/net/ens785f1/device/sriov_numvfs sleep 1 echo 1 > /sys/class/net/ens785f0/device/sriov_numvfs echo 1 > /sys/class/net/ens785f1/device/sriov_numvfs ip link set ens785f1 vf 0 trust on ip link set ens785f0 vf 0 trust on done Fixes: 7c710869d64e ("ice: Add handlers for VF netdevice operations") Cc: <stable(a)vger.kernel.org> Signed-off-by: Brett Creeley <brett.creeley(a)intel.com> Tested-by: Konrad Jankowski <konrad0.jankowski(a)intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen(a)intel.com> Signed-off-by: Jacob Keller <jacob.e.keller(a)intel.com> --- .../net/ethernet/intel/ice/ice_virtchnl_pf.c | 25 +++++++++++++++++++ .../net/ethernet/intel/ice/ice_virtchnl_pf.h | 5 ++++ 2 files changed, 30 insertions(+) diff --git a/drivers/net/ethernet/intel/ice/ice_virtchnl_pf.c b/drivers/net/ethernet/intel/ice/ice_virtchnl_pf.c index a78e8f00cf71..a0b8436f50ba 100644 --- a/drivers/net/ethernet/intel/ice/ice_virtchnl_pf.c +++ b/drivers/net/ethernet/intel/ice/ice_virtchnl_pf.c @@ -646,6 +646,8 @@ void ice_free_vfs(struct ice_pf *pf) set_bit(ICE_VF_STATE_DIS, pf->vf[i].vf_states); ice_free_vf_res(&pf->vf[i]); } + + mutex_destroy(&pf->vf[i].cfg_lock); } if (ice_sriov_free_msix_res(pf)) @@ -1894,6 +1896,8 @@ static void ice_set_dflt_settings_vfs(struct ice_pf *pf) */ ice_vf_ctrl_invalidate_vsi(vf); ice_vf_fdir_init(vf); + + mutex_init(&vf->cfg_lock); } } @@ -4082,6 +4086,8 @@ ice_set_vf_port_vlan(struct net_device *netdev, int vf_id, u16 vlan_id, u8 qos, return 0; } + mutex_lock(&vf->cfg_lock); + vf->port_vlan_info = vlanprio; if (vf->port_vlan_info) @@ -4091,6 +4097,7 @@ ice_set_vf_port_vlan(struct net_device *netdev, int vf_id, u16 vlan_id, u8 qos, dev_info(dev, "Clearing port VLAN on VF %d\n", vf_id); ice_vc_reset_vf(vf); + mutex_unlock(&vf->cfg_lock); return 0; } @@ -4465,6 +4472,15 @@ void ice_vc_process_vf_msg(struct ice_pf *pf, struct ice_rq_event_info *event) return; } + /* VF is being configured in another context that triggers a VFR, so no + * need to process this message + */ + if (!mutex_trylock(&vf->cfg_lock)) { + dev_info(dev, "VF %u is being configured in another context that will trigger a VFR, so there is no need to handle this message\n", + vf->vf_id); + return; + } + switch (v_opcode) { case VIRTCHNL_OP_VERSION: err = ice_vc_get_ver_msg(vf, msg); @@ -4553,6 +4569,8 @@ void ice_vc_process_vf_msg(struct ice_pf *pf, struct ice_rq_event_info *event) dev_info(dev, "PF failed to honor VF %d, opcode %d, error %d\n", vf_id, v_opcode, err); } + + mutex_unlock(&vf->cfg_lock); } /** @@ -4668,6 +4686,8 @@ int ice_set_vf_mac(struct net_device *netdev, int vf_id, u8 *mac) return -EINVAL; } + mutex_lock(&vf->cfg_lock); + /* VF is notified of its new MAC via the PF's response to the * VIRTCHNL_OP_GET_VF_RESOURCES message after the VF has been reset */ @@ -4686,6 +4706,7 @@ int ice_set_vf_mac(struct net_device *netdev, int vf_id, u8 *mac) } ice_vc_reset_vf(vf); + mutex_unlock(&vf->cfg_lock); return 0; } @@ -4715,11 +4736,15 @@ int ice_set_vf_trust(struct net_device *netdev, int vf_id, bool trusted) if (trusted == vf->trusted) return 0; + mutex_lock(&vf->cfg_lock); + vf->trusted = trusted; ice_vc_reset_vf(vf); dev_info(ice_pf_to_dev(pf), "VF %u is now %strusted\n", vf_id, trusted ?

This issue can be seen using the following commands: for i in {0..50}; do rmmod ice modprobe ice sleep 1 echo 1 > /sys/class/net/ens785f0/device/sriov_numvfs echo 1 > /sys/class/net/ens785f1/device/sriov_numvfs ip link set ens785f1 vf 0 trust on ip link set ens785f0 vf 0 trust on sleep 2 echo 0 > /sys/class/net/ens785f0/device/sriov_numvfs echo 0 > /sys/class/net/ens785f1/device/sriov_numvfs sleep 1 echo 1 > /sys/class/net/ens785f0/device/sriov_numvfs echo 1 > /sys/class/net/ens785f1/device/sriov_numvfs ip link set ens785f1 vf 0 trust on ip link set ens785f0 vf 0 trust on done Fixes: 7c710869d64e ("ice: Add handlers for VF netdevice operations") Cc: <stable(a)vger.kernel.org> # 5.14.x Signed-off-by: Brett Creeley <brett.creeley(a)intel.com> Tested-by: Konrad Jankowski <konrad0.jankowski(a)intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen(a)intel.com> Signed-off-by: Jacob Keller <jacob.e.keller(a)intel.com> --- This should apply to 5.14.x .../net/ethernet/intel/ice/ice_virtchnl_pf.c | 25 +++++++++++++++++++ .../net/ethernet/intel/ice/ice_virtchnl_pf.h | 5 ++++ 2 files changed, 30 insertions(+) diff --git a/drivers/net/ethernet/intel/ice/ice_virtchnl_pf.c b/drivers/net/ethernet/intel/ice/ice_virtchnl_pf.c index 7e3ae4cc17a3..d2f79d579745 100644 --- a/drivers/net/ethernet/intel/ice/ice_virtchnl_pf.c +++ b/drivers/net/ethernet/intel/ice/ice_virtchnl_pf.c @@ -646,6 +646,8 @@ void ice_free_vfs(struct ice_pf *pf) set_bit(ICE_VF_STATE_DIS, pf->vf[i].vf_states); ice_free_vf_res(&pf->vf[i]); } + + mutex_destroy(&pf->vf[i].cfg_lock); } if (ice_sriov_free_msix_res(pf)) @@ -1892,6 +1894,8 @@ static void ice_set_dflt_settings_vfs(struct ice_pf *pf) */ ice_vf_ctrl_invalidate_vsi(vf); ice_vf_fdir_init(vf); + + mutex_init(&vf->cfg_lock); } } @@ -4080,6 +4084,8 @@ ice_set_vf_port_vlan(struct net_device *netdev, int vf_id, u16 vlan_id, u8 qos, return 0; } + mutex_lock(&vf->cfg_lock); + vf->port_vlan_info = vlanprio; if (vf->port_vlan_info) @@ -4089,6 +4095,7 @@ ice_set_vf_port_vlan(struct net_device *netdev, int vf_id, u16 vlan_id, u8 qos, dev_info(dev, "Clearing port VLAN on VF %d\n", vf_id); ice_vc_reset_vf(vf); + mutex_unlock(&vf->cfg_lock); return 0; } @@ -4463,6 +4470,15 @@ void ice_vc_process_vf_msg(struct ice_pf *pf, struct ice_rq_event_info *event) return; } + /* VF is being configured in another context that triggers a VFR, so no + * need to process this message + */ + if (!mutex_trylock(&vf->cfg_lock)) { + dev_info(dev, "VF %u is being configured in another context that will trigger a VFR, so there is no need to handle this message\n", + vf->vf_id); + return; + } + switch (v_opcode) { case VIRTCHNL_OP_VERSION: err = ice_vc_get_ver_msg(vf, msg); @@ -4551,6 +4567,8 @@ void ice_vc_process_vf_msg(struct ice_pf *pf, struct ice_rq_event_info *event) dev_info(dev, "PF failed to honor VF %d, opcode %d, error %d\n", vf_id, v_opcode, err); } + + mutex_unlock(&vf->cfg_lock); } /** @@ -4666,6 +4684,8 @@ int ice_set_vf_mac(struct net_device *netdev, int vf_id, u8 *mac) return -EINVAL; } + mutex_lock(&vf->cfg_lock); + /* VF is notified of its new MAC via the PF's response to the * VIRTCHNL_OP_GET_VF_RESOURCES message after the VF has been reset */ @@ -4684,6 +4704,7 @@ int ice_set_vf_mac(struct net_device *netdev, int vf_id, u8 *mac) } ice_vc_reset_vf(vf); + mutex_unlock(&vf->cfg_lock); return 0; } @@ -4713,11 +4734,15 @@ int ice_set_vf_trust(struct net_device *netdev, int vf_id, bool trusted) if (trusted == vf->trusted) return 0; + mutex_lock(&vf->cfg_lock); + vf->trusted = trusted; ice_vc_reset_vf(vf); dev_info(ice_pf_to_dev(pf), "VF %u is now %strusted\n", vf_id, trusted ?

FAILED: patch "[PATCH] drm/mediatek: mtk_dsi: Avoid EPROBE_DEFER loop with external" failed to apply to 5.15-stable tree

Now that the DSI hosts/devices probe sequence is documented, we can do adjustments to the mtk_dsi driver as to both fix now and make sure to avoid this situation in the future: for this, following what is documented in drm_bridge.c, move the mtk_dsi component_add() to the mtk_dsi_ops.attach callback and delete it in the detach callback; keeping in mind that we are registering a drm_bridge for our DSI, which is only used/attached if the DSI Host is bound, it wouldn't make sense to keep adding our bridge at probe time (as it would be useless to have it if mtk_dsi_ops.attach() fails!), so also move that one to the dsi host attach function (and remove it in detach).
