The "skb" is freed by the transmit code in cxgb4_ofld_send() and we shouldn't use it again. But in the current code, if we hit an error later on in the function then the clean up code will call kfree_skb(skb) and so it causes a double free. Set the "skb" to NULL and that makes the kfree_skb() a no-op. Fixes: d25f2f71 ("crypto: chtls - Program the TLS session Key") Signed-off-by:

The .x25_addr[] address comes from the user and is not necessarily NUL terminated. This leads to a couple problems. The first problem is that the strlen() in x25_bind() can read beyond the end of the buffer. The second problem is more subtle and could result in memory corruption. The call tree is: x25_connect() --> x25_write_internal() --> x25_addr_aton() The .x25_addr[] buffers are copied to the "addresses" buffer from x25_write_internal() so it will lead to stack corruption. Verify that the strings are NUL terminated and return -EINVAL if they are not.

In commit 682cd3cf ("tipc: confgiure and apply UDP bearer MTU on running links"), we introduced a function to change UDP bearer MTU and applied this new value across existing per-link. However, we did not apply this new MTU value at node level. This lead to packet dropped at link level if its size is greater than new MTU value. To fix this issue, we also apply this new MTU value for node level. Fixes: 682cd3cf ("tipc: confgiure and apply UDP bearer MTU on running links") Acked-by:

It was observed that sending data via batadv over vxlan (on top of wireguard) reduced the performance massively compared to raw ethernet or batadv on raw ethernet. A check of perf data showed that the vxlan_build_skb was calling all the time pskb_expand_head to allocate enough headroom for: min_headroom = LL_RESERVED_SPACE(dst->dev) + dst->header_len + VXLAN_HLEN + iphdr_len; But the vxlan_config_apply only requested needed headroom for: lowerdev->hard_header_len + VXLAN6_HEADROOM or VXLAN_HEADROOM So it completely ignored the needed_headroom of the lower device. The first caller of net_dev_xmit could therefore never make sure that enough headroom was allocated for the rest of the transmit path. Cc: Annika Wickert <annika.wickert@exaring.de> Signed-off-by:

In the error handling in c_can_power_up(), there are two bugs: 1) c_can_pm_runtime_get_sync() will increase usage counter if device is not empty. Forgetting to call c_can_pm_runtime_put_sync() will result in a reference leak here. 2) c_can_reset_ram() operation will set start bit when enable is true. We should clear it in the error handling. We fix it by adding c_can_pm_runtime_put_sync() for 1), and c_can_reset_ram(enable is false) for 2) in the error handling.

Losing arbitration is normal in a CAN-bus network, it means that a higher priority frame is being send and the pending message will be retried later. Hence most driver only increment arbitration_lost, but the sun4i driver also incremeants tx_error, causing errors to be reported on a normal functioning CAN-bus. So stop counting them as errors.

GPIO_ACTIVE_x flags are not correct in the context of interrupt flags. These are simple defines so they could be used in DTS but they will not have the same meaning: 1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE 2. GPIO_ACTIVE_LOW = 1 = IRQ_TYPE_EDGE_RISING Correct the interrupt flags, assuming the author of the code wanted same logical behavior behind the name "ACTIVE_xxx", this is: ACTIVE_LOW => IRQ_TYPE_LEVEL_LOW ACTIVE_HIGH => IRQ_TYPE_LEVEL_HIGH Fixes: a1a8b459 ("NFC: pn544: i2c: Add DTS Documentation") Fixes: 6be88670 ("NFC: nxp-nci_i2c: Add I2C support to NXP NCI driver") Fixes: e3b32922 ("dt-bindings: can: tcan4x5x: Update binding to use interrupt property") Signed-off-by:
