When run below command to mount a yaffs2 FS to nor flash, there is kernel panic as below: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000020 ......

If it is not NAND flash, NULL will be returned. This causes kernel panic if the ret value is not checked whether it is NULL or not. So, replace IS_ERR with IS_ERR_OR_NULL to check both ERR and NULL.

commit 4a3e0aed upstream. mv88e6xxx_port_ppu_updates() interpretes data in the PORT_STS register incorrectly for internal ports (ie no PPU). In these cases, the PHY_DETECT bit indicates link status. This results in forcing the MAC state whenever the PHY link goes down which is not intended. As a side effect, LED's configured to show link status stay lit even though the physical link is down. Add a check in mac_link_down and mac_link_up to see if it concerns an external port and only then, look at PPU status. Fixes: 5d5b231d (net: dsa: mv88e6xxx: use PHY_DETECT in mac_link_up/mac_link_down) Reported-by:

commit 5c976a56 upstream. Bridging, and possibly other upper stack gizmos, adds the lower device's netdev->dev_addr to its own uc list, and then requests it be deleted when the upper bridge device is removed. This delete request also happens with the bridging vlan_filtering is enabled and then disabled. Bonding has a similar behavior with the uc list, but since it also uses set_mac to manage netdev->dev_addr, it doesn't have the same the failure case. Because we store our netdev->dev_addr in our uc list, we need to ignore the delete request from dev_uc_sync so as to not lose the address and all hope of communicating. Note that ndo_set_mac_address is expressly changing netdev->dev_addr, so no limitation is set there. Fixes: 2a654540 ("ionic: Add Rx filter and rx_mode ndo support") Signed-off-by:

commit 9fde506e upstream. When skb_match is NULL, it means we received a PTP IRQ for a timestamp ID that the kernel has no idea about, since there is no skb in the timestamping queue with that timestamp ID. This is a grave error and not something to just "continue" over. So print a big warning in case this happens. Also, move the check above ocelot_get_hwtimestamp(), there is no point in reading the full 64-bit current PTP time if we're not going to do anything with it anyway for this skb.

commit 14132690 upstream. Introduction of lockless subqueues broke the class statistics. Before the change stats were accumulated in `bstats' and `qstats' on the stack which was then copied to struct gnet_dump. After the change the `bstats' and `qstats' are initialized to 0 and never updated, yet still fed to gnet_dump. The code updates the global qdisc->cpu_bstats and qdisc->cpu_qstats instead, clobbering them. Most likely a copy-paste error from the code in mqprio_dump(). __gnet_stats_copy_basic() and __gnet_stats_copy_queue() accumulate the values for per-CPU case but for global stats they overwrite the value, so only stats from the last loop iteration / tc end up in sch->[bq]stats. Use the on-stack [bq]stats variables again and add the stats manually in the global case.

commit 97794170 upstream. In commit e11f5bd8 ("drm: Add support for DP 1.4 Compliance edid corruption test") the function connector_bad_edid() started assuming that the memory for the EDID passed to it was big enough to hold `edid[0x7e] + 1` blocks of data (1 extra for the base block). It completely ignored the fact that the function was passed `num_blocks` which indicated how much memory had been allocated for the EDID. Let's fix this by adding a bounds check. This is important for handling the case where there's an error in the first block of the EDID. In that case we will call connector_bad_edid() without having re-allocated memory based on `edid[0x7e]`.

commit 9b024201 upstream. Change kstrtou32() argument 'base' to be zero instead of 'len'. It works by chance for setting one bit value, but it is not supposed to work in case value passed to mlxreg_io_attr_store() is greater than 1. It works for example, for: echo 1 > /sys/devices/platform/mlxplat/mlxreg-io/hwmon/.../jtag_enable But it will fail for: echo n > /sys/devices/platform/mlxplat/mlxreg-io/hwmon/.../jtag_enable, where n > 1. The flow for input buffer conversion is as below: _kstrtoull(const char *s, unsigned int base, unsigned long long *res) calls: rv = _parse_integer(s, base, &_res); For the second case, where n > 1: - _parse_integer() converts 's' to 'val'. For n=2, 'len' is set to 2 (string buffer is 0x32 0x0a), for n=3 'len' is set to 3 (string buffer 0x33 0x0a), etcetera. - 'base' is equal or greater then '2' (length of input buffer). As a result, _parse_integer() exits with result zero (rv): rv = 0; while (1) { ... if (val >= base)-> (2 >= 2) break; ... rv++; ... } And _kstrtoull() in their turn will fail: if (rv == 0) return -EINVAL; Fixes: 5ec4a8ac ("platform/mellanox: Introduce support for Mellanox register access driver") Signed-off-by:

commit 332fdf95 upstream. Currently, mlxsw allows cooling states to be set above the maximum cooling state supported by the driver: # cat /sys/class/thermal/thermal_zone2/cdev0/type mlxsw_fan # cat /sys/class/thermal/thermal_zone2/cdev0/max_state 10 # echo 18 > /sys/class/thermal/thermal_zone2/cdev0/cur_state # echo $? 0 This results in out-of-bounds memory accesses when thermal state transition statistics are enabled (CONFIG_THERMAL_STATISTICS=y), as the transition table is accessed with a too large index (state) [1]. According to the thermal maintainer, it is the responsibility of the driver to reject such operations [2]. Therefore, return an error when the state to be set exceeds the maximum cooling state supported by the driver. To avoid dead code, as suggested by the thermal maintainer [3], partially revert commit a421ce08 ("mlxsw: core: Extend cooling device with cooling levels") that tried to interpret these invalid cooling states (above the maximum) in a special way. The cooling levels array is not removed in order to prevent the fans going below 20% PWM, which would cause them to get stuck at 0% PWM.

commit 58e7dcc9 upstream. 'params' is allocated in digital_tg_listen_mdaa(), but not free when digital_send_cmd() failed, which will cause memory leak. Fix it by freeing 'params' if digital_send_cmd() return failed. Fixes: 1c7a4c24 ("NFC Digital: Add target NFC-DEP support") Signed-off-by:

commit 40507e7a upstream. After recent cleanups, gcc started warning about a suspicious memcpy() call during the s2io_io_resume() function: In function '__dev_addr_set', inlined from 'eth_hw_addr_set' at include/linux/etherdevice.h:318:2, inlined from 's2io_set_mac_addr' at drivers/net/ethernet/neterion/s2io.c:5205:2, inlined from 's2io_io_resume' at drivers/net/ethernet/neterion/s2io.c:8569:7: arch/x86/include/asm/string_32.h:182:25: error: '__builtin_memcpy' accessing 6 bytes at offsets 0 and 2 overlaps 4 bytes at offset 2 [-Werror=restrict] 182 | #define memcpy(t, f, n) __builtin_memcpy(t, f, n) | ^~~~~~~~~~~~~~~~~~~~~~~~~ include/linux/netdevice.h:4648:9: note: in expansion of macro 'memcpy' 4648 | memcpy(dev->dev_addr, addr, len); | ^~~~~~ What apparently happened is that an old cleanup changed the calling conventions for s2io_set_mac_addr() from taking an ethernet address as a character array to taking a struct sockaddr, but one of the callers was not changed at the same time. Change it to instead call the low-level do_s2io_prog_unicast() function that still takes the old argument type.

commit ef1100ef upstream. When the ksz module is installed and removed using rmmod, kernel crashes with null pointer dereferrence error. During rmmod, ksz_switch_remove function tries to cancel the mib_read_workqueue using cancel_delayed_work_sync routine and unregister switch from dsa. During dsa_unregister_switch it calls ksz_mac_link_down, which in turn reschedules the workqueue since mib_interval is non-zero. Due to which queue executed after mib_interval and it tries to access dp->slave. But the slave is unregistered in the ksz_switch_remove function. Hence kernel crashes. To avoid this crash, before canceling the workqueue, resetted the mib_interval to 0. v1 -> v2: -Removed the if condition in ksz_mib_read_work Fixes: 469b390e ("net: dsa: microchip: use delayed_work instead of timer + work") Signed-off-by:

commit 075da584 upstream. Some old IPs do not provide the hardware feature register. On these IPs, this register is read 0x00000000. In old driver version, this feature was handled but a regression came with the commit f10a6a35 ("stmmac: rework get_hw_feature function"). Indeed, this commit removes the return value in dma->get_hw_feature(). This return value was used to indicate the validity of retrieved information and used later on in stmmac_hw_init() to override priv->plat data if this hardware feature were valid. This patch restores the return code in ->get_hw_feature() in order to indicate the hardware feature validity and override priv->plat data only if this hardware feature is valid.

commit 0bc73ad4 upstream. Due to current HW arch limitations, RX-FCS (scattering FCS frame field to software) and RX-port-timestamp (improved timestamp accuracy on the receive side) can't work together. RX-port-timestamp is not controlled by the user and it is enabled by default when supported by the HW/FW. This patch sets RX-port-timestamp opposite to RX-FCS configuration.
