2018-06-15mlxsw: spectrum_switchdev: Fix port_vlan refcountingPetr Machata
Switchdev notifications for addition of SWITCHDEV_OBJ_ID_PORT_VLAN are distributed not only on clean addition, but also when flags on an existing VLAN are changed. mlxsw_sp_bridge_port_vlan_add() calls mlxsw_sp_port_vlan_get() to get at the port_vlan in question, which implicitly references the object. This then leads to discrepancies in reference counting when the VLAN is removed. spectrum.c warns about the problem when the module is removed: [13578.493090] WARNING: CPU: 0 PID: 2454 at drivers/net/ethernet/mellanox/mlxsw/spectrum.c:2973 mlxsw_sp_port_remove+0xfd/0x110 [mlxsw_spectrum] [...] [13578.627106] Call Trace: [13578.629617] mlxsw_sp_fini+0x2a/0xe0 [mlxsw_spectrum] [13578.634748] mlxsw_core_bus_device_unregister+0x3e/0x130 [mlxsw_core] [13578.641290] mlxsw_pci_remove+0x13/0x40 [mlxsw_pci] [13578.646238] pci_device_remove+0x31/0xb0 [13578.650244] device_release_driver_internal+0x14f/0x220 [13578.655562] driver_detach+0x32/0x70 [13578.659183] bus_remove_driver+0x47/0xa0 [13578.663134] pci_unregister_driver+0x1e/0x80 [13578.667486] mlxsw_sp_module_exit+0xc/0x3fa [mlxsw_spectrum] [13578.673207] __x64_sys_delete_module+0x13b/0x1e0 [13578.677888] ? exit_to_usermode_loop+0x78/0x80 [13578.682374] do_syscall_64+0x39/0xe0 [13578.685976] entry_SYSCALL_64_after_hwframe+0x44/0xa9 Fix by putting the port_vlan when mlxsw_sp_port_vlan_bridge_join() determines it's a flag-only change.

2018-06-15stmmac: added support for 802.1ad vlan strippingElad Nachman
stmmac reception handler calls stmmac_rx_vlan() to strip the vlan before calling napi_gro_receive(). The function assumes VLAN tagged frames are always tagged with 802.1Q protocol, and assigns ETH_P_8021Q to the skb by hard-coding the parameter on call to __vlan_hwaccel_put_tag() . This causes packets not to be passed to the VLAN slave if it was created with 802.1AD protocol (ip link add link eth0 eth0.100 type vlan proto 802.1ad id 100). This fix passes the protocol from the VLAN header into __vlan_hwaccel_put_tag() instead of using the hard-coded value of ETH_P_8021Q. NETIF_F_HW_VLAN_STAG_RX check was added and the strip action is now dependent on the correct combination of features and the detected vlan tag. NETIF_F_HW_VLAN_STAG_RX feature was added to be in line with the driver actual abilities.

Currently, atomic_commit() does not handle bo operations for cursor plane, as a result the bo assigned for cursor plane in dm_plane_helper_prepare_fb() is not coherent with the updates to the same made in dc code.This mismatch leads to "bo" corruption and hence crashes during S3 entry.

2018-06-13drm/amdgpu: Grab/put runtime PM references in atomic_commit_tail()Lyude Paul
So, unfortunately I recently made the discovery that in the upstream kernel, the only reason that amdgpu is not currently suffering from issues with runtime PM putting the GPU into suspend while it's driving displays is due to the fact that on most prime systems, we have sound devices associated with the GPU that hold their own runtime PM ref for the GPU. What this means however, is that in the event that there isn't any kind of sound device active (which can easily be reproduced by building a kernel with sound drivers disabled), the GPU will fall asleep even when there's displays active. This appears to be in part due to the fact that amdgpu has not actually ever relied on it's rpm_idle() function to be the only thing keeping it running, and normally grabs it's own power references whenever there are displays active (as can be seen with the original pre-DC codepath in amdgpu_display_crtc_set_config() in amdgpu_display.c). This means it's very likely that this bug was introduced during the switch over the DC. So to fix this, we start grabbing runtime PM references every time we enable a previously disabled CRTC in atomic_commit_tail(). This appears to be the correct solution, as it matches up with what i915 does in i915/intel_runtime_pm.c. The one sideaffect of this is that we ignore the variable that the pre-DC code used to use for tracking when it needed runtime PM refs, adev->have_disp_power_ref. This is mainly because there's no way for a driver to tell whether or not all of it's CRTCs are enabled or disabled when we've begun committing an atomic state, as there may be CRTC commits happening in parallel that aren't contained within the atomic state being committed. So, it's safer to just get/put a reference for each CRTC being enabled or disabled in the new atomic state.

2018-06-12treewide: Use array_size() in kvzalloc_node()Kees Cook
The kvzalloc_node() function has no 2-factor argument form, so multiplication factors need to be wrapped in array_size().

2018-06-12treewide: Use array_size() in vzalloc_node()Kees Cook
The vzalloc_node() function has no 2-factor argument form, so multiplication factors need to be wrapped in array_size(). This patch replaces cases of: vzalloc_node(a * b, node) with: vzalloc_node(array_size(a, b), node) as well as handling cases of: vzalloc_node(a * b * c, node) with: vzalloc_node(array3_size(a, b, c), node) This does, however, attempt to ignore constant size factors like: vzalloc_node(4 * 1024, node) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( vzalloc_node( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | vzalloc_node( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT; typedef u8; typedef __u8; @@ ( vzalloc_node( - sizeof(u8) * (COUNT) + COUNT , ...) | vzalloc_node( - sizeof(__u8) * (COUNT) + COUNT , ...) | vzalloc_node( - sizeof(char) * (COUNT) + COUNT , ...) | vzalloc_node( - sizeof(unsigned char) * (COUNT) + COUNT , ...) | vzalloc_node( - sizeof(u8) * COUNT + COUNT , ...) | vzalloc_node( - sizeof(__u8) * COUNT + COUNT , ...) | vzalloc_node( - sizeof(char) * COUNT + COUNT , ...) | vzalloc_node( - sizeof(unsigned char) * COUNT + COUNT , ...) ) // 2-factor product with sizeof(type/expression) and identifier or constant. @@ type TYPE; expression THING; identifier COUNT_ID; constant COUNT_CONST; @@ ( vzalloc_node( - sizeof(TYPE) * (COUNT_ID) + array_size(COUNT_ID, sizeof(TYPE)) , ...) | vzalloc_node( - sizeof(TYPE) * COUNT_ID + array_size(COUNT_ID, sizeof(TYPE)) , ...) | vzalloc_node( - sizeof(TYPE) * (COUNT_CONST) + array_size(COUNT_CONST, sizeof(TYPE)) , ...) | vzalloc_node( - sizeof(TYPE) * COUNT_CONST + array_size(COUNT_CONST, sizeof(TYPE)) , ...) | vzalloc_node( - sizeof(THING) * (COUNT_ID) + array_size(COUNT_ID, sizeof(THING)) , ...) | vzalloc_node( - sizeof(THING) * COUNT_ID + array_size(COUNT_ID, sizeof(THING)) , ...) | vzalloc_node( - sizeof(THING) * (COUNT_CONST) + array_size(COUNT_CONST, sizeof(THING)) , ...) | vzalloc_node( - sizeof(THING) * COUNT_CONST + array_size(COUNT_CONST, sizeof(THING)) , ...) ) // 2-factor product, only identifiers. @@ identifier SIZE, COUNT; @@ vzalloc_node( - SIZE * COUNT + array_size(COUNT, SIZE) , ...) // 3-factor product with 1 sizeof(type) or sizeof(expression), with // redundant parens removed. @@ expression THING; identifier STRIDE, COUNT; type TYPE; @@ ( vzalloc_node( - sizeof(TYPE) * (COUNT) * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vzalloc_node( - sizeof(TYPE) * (COUNT) * STRIDE + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vzalloc_node( - sizeof(TYPE) * COUNT * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vzalloc_node( - sizeof(TYPE) * COUNT * STRIDE + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vzalloc_node( - sizeof(THING) * (COUNT) * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | vzalloc_node( - sizeof(THING) * (COUNT) * STRIDE + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | vzalloc_node( - sizeof(THING) * COUNT * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | vzalloc_node( - sizeof(THING) * COUNT * STRIDE + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) ) // 3-factor product with 2 sizeof(variable), with redundant parens removed. @@ expression THING1, THING2; identifier COUNT; type TYPE1, TYPE2; @@ ( vzalloc_node( - sizeof(TYPE1) * sizeof(TYPE2) * COUNT + array3_size(COUNT, sizeof(TYPE1), sizeof(TYPE2)) , ...) | vzalloc_node( - sizeof(TYPE1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(TYPE1), sizeof(TYPE2)) , ...) | vzalloc_node( - sizeof(THING1) * sizeof(THING2) * COUNT + array3_size(COUNT, sizeof(THING1), sizeof(THING2)) , ...) | vzalloc_node( - sizeof(THING1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(THING1), sizeof(THING2)) , ...) | vzalloc_node( - sizeof(TYPE1) * sizeof(THING2) * COUNT + array3_size(COUNT, sizeof(TYPE1), sizeof(THING2)) , ...) | vzalloc_node( - sizeof(TYPE1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(TYPE1), sizeof(THING2)) , ...) ) // 3-factor product, only identifiers, with redundant parens removed. @@ identifier STRIDE, SIZE, COUNT; @@ ( vzalloc_node( - (COUNT) * STRIDE * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc_node( - COUNT * (STRIDE) * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc_node( - COUNT * STRIDE * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc_node( - (COUNT) * (STRIDE) * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc_node( - COUNT * (STRIDE) * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc_node( - (COUNT) * STRIDE * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc_node( - (COUNT) * (STRIDE) * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vzalloc_node( - COUNT * STRIDE * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) ) // Any remaining multi-factor products, first at least 3-factor products // when they're not all constants... @@ expression E1, E2, E3; constant C1, C2, C3; @@ ( vzalloc_node(C1 * C2 * C3, ...) | vzalloc_node( - E1 * E2 * E3 + array3_size(E1, E2, E3) , ...) ) // And then all remaining 2 factors products when they're not all constants. @@ expression E1, E2; constant C1, C2; @@ ( vzalloc_node(C1 * C2, ...) | vzalloc_node( - E1 * E2 + array_size(E1, E2) , ...) ) Signed-off-by: Kees Cook <keescook@chromium.org>
