* s390: chp: handle CRW_ERC_INIT for channel-path status changeDong Jia Shi2017-07-131-0/+1
| | | | | | | | | | | | | When channel path is identified as the report source code (RSC) of a CRW, and initialized (CRW_ERC_INIT) is recognized as the error recovery code (ERC) by the channel subsystem, it indicates a "path has come" event. Let's handle this case in chp_process_crw().

| * sfc: don't read beyond unicast address listBert Kenward2017-07-121-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | If we have more than 32 unicast MAC addresses assigned to an interface we will read beyond the end of the address table in the driver when adding filters. The next 256 entries store multicast addresses, so we will end up attempting to insert duplicate filters, which is mostly harmless. If we add more than 288 unicast addresses we will then read past the multicast address table, which is likely to be more exciting.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The lower level nl80211 code in cfg80211 ensures that "len" is between 25 and NL80211_ATTR_FRAME (2304). We subtract DOT11_MGMT_HDR_LEN (24) from "len" so thats's max of 2280. However, the action_frame->data[] buffer is only BRCMF_FIL_ACTION_FRAME_SIZE (1800) bytes long so this memcpy() can overflow. memcpy(action_frame->data, &buf[DOT11_MGMT_HDR_LEN], le16_to_cpu(action_frame->len)); Cc: stable@vger.kernel.org # 3.9.x Fixes: 18e2f61db3b70 ("brcmfmac: P2P action frame tx.")

| * mlxsw: spectrum_router: Fix use-after-free in route replaceIdo Schimmel2017-07-121-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While working on IPv6 route replace I realized we can have a use-after-free in IPv4 in case the replaced route is offloaded and the only one using its FIB info. The problem is that fib_table_insert() drops the reference on the FIB info of the replaced routes which is eventually freed via call_rcu(). Since the driver doesn't hold a reference on this FIB info it can cause a use-after-free when it tries to clear the RTNH_F_OFFLOAD flag stored in fi->fib_flags. After running the following commands in a loop for enough time with a KASAN enabled kernel I finally got the below trace. $ ip route add 192.168.50.0/24 via 192.168.200.1 dev enp3s0np3 $ ip route replace 192.168.50.0/24 dev enp3s0np5 $ ip route del 192.168.50.0/24 dev enp3s0np5 BUG: KASAN: use-after-free in mlxsw_sp_fib_entry_offload_unset+0xa7/0x120 [mlxsw_spectrum] Read of size 4 at addr ffff8803717d9820 by task kworker/u4:2/55 [...] ? mlxsw_sp_fib_entry_offload_unset+0xa7/0x120 [mlxsw_spectrum] ? mlxsw_sp_fib_entry_offload_unset+0xa7/0x120 [mlxsw_spectrum] ? mlxsw_sp_router_neighs_update_work+0x1cd0/0x1ce0 [mlxsw_spectrum] ? mlxsw_sp_fib_entry_offload_unset+0xa7/0x120 [mlxsw_spectrum] __asan_load4+0x61/0x80 mlxsw_sp_fib_entry_offload_unset+0xa7/0x120 [mlxsw_spectrum] mlxsw_sp_fib_entry_offload_refresh+0xb6/0x370 [mlxsw_spectrum] mlxsw_sp_router_fib_event_work+0xd1c/0x2780 [mlxsw_spectrum] [...] Freed by task 5131: save_stack_trace+0x16/0x20 save_stack+0x46/0xd0 kasan_slab_free+0x70/0xc0 kfree+0x144/0x570 free_fib_info_rcu+0x2e7/0x410 rcu_process_callbacks+0x4f8/0xe30 __do_softirq+0x1d3/0x9e2 Fix this by taking a reference on the FIB info when creating the nexthop group it represents and drop it when the group is destroyed.

| * cxgb4: fix BUG() on interrupt deallocating path of ULDGuilherme G. Piccoli2017-07-112-22/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the introduction of ULD (Upper-Layer Drivers), the MSI-X deallocating path changed in cxgb4: the driver frees the interrupts of ULD when unregistering it or on shutdown PCI handler. Problem is that if a MSI-X is not freed before deallocated in the PCI layer, it will trigger a BUG() due to still "alive" interrupt being tentatively quiesced. The below trace was observed when doing a simple unbind of Chelsio's adapter PCI function, like: "echo 001e:80:00.4 > /sys/bus/pci/drivers/cxgb4/unbind" Trace: kernel BUG at drivers/pci/msi.c:352!

This list is a 256-bit bitmap. The code that sets up the bitmap falls apart on big-endian architecture. __set_bit() does not work because it operates on long types whereas the firmware interface is defined in u32 types, causing bits in the wrong 32-bit word to be set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Latest change in open-lldp code uses bytes 6-11 of perm_addr buffer as the Ethernet source address for the host TLV packet. Since our driver does not fill these bytes, they stay at zero and the open-lldp code ends up sending the TLV packet with zero source address and the switch drops this packet. The fix is to initialize these bytes to 0xff. The open-lldp code considers 0xff:ff:ff:ff:ff:ff as the invalid address and falls back to use the host's mac address as the Ethernet source address.

Sometimes the ACPI nodes describing these contain a SERIAL_TYPE_I2C ACPI resource. Before this commit the presence of this resource would cause the i2c-core to create a /sys/bus/i2c/devices/i2c-LNXVIDEO:00 device for this with a modalias of: "i2c:LNXVIDEO:00". There is no i2c driver for this custom HID, the acpi-video driver binds directly to the ACPI device /sys/bus/acpi/devices/LNXVIDEO\:00 which has a modalias of "acpi:LNXVIDEO:" . Not only is the creation of an i2c-client for this undesirable, it is actually causing problems. This weird pseudo-resource claims an i2c speed of 100KHz and typically points to the i2c bus which is used by the touchscreen controller. Some touchscreen controllers only work properly at 400KHz, at 100KHz they cause errors like these: i2c_designware 80860F41:03: i2c_dw_handle_tx_abort: lost arbitration i2c_designware 80860F41:03: i2c_dw_handle_tx_abort: lost arbitration i2c_designware 80860F41:03: i2c_dw_handle_tx_abort: lost arbitration i2c_designware 80860F41:03: i2c_dw_handle_tx_abort: lost arbitration silead_ts i2c-MSSL1680:00: Registers clear error -11 This commit makes the i2c-core ignore LNXVIDEO compatible ACPI devices which has 2 positive results: 1) The bogus i2c-client for these is no longer created. 2) i2c_acpi_lookup_speed now ignores the 100KHz speed from the pseudo i2c-resouce and properly returns 400KHz as speed for the touchscreen i2c bus, fixing the touchscreen not working on various devies.
