The following commit has been merged in the master branch: commit f872de8185acf1b48b954ba5bd8f9bc0a0d14016 Author: Xiyu Yang <xiyuyang19(a)fudan.edu.cn> Date: Wed Apr 15 16:31:50 2020 +0800 batman-adv: Fix refcnt leak in batadv_show_throughput_override batadv_show_throughput_override() invokes batadv_hardif_get_by_netdev(), which gets a batadv_hard_iface object from net_dev with increased refcnt and its reference is assigned to a local pointer 'hard_iface'. When batadv_show_throughput_override() returns, "hard_iface" becomes invalid, so the refcount should be decreased to keep refcount balanced. The issue happens in the normal path of batadv_show_throughput_override(), which forgets to decrease the refcnt increased by batadv_hardif_get_by_netdev() before the function returns, causing a refcnt leak. Fix this issue by calling batadv_hardif_put() before the batadv_show_throughput_override() returns in the normal path.

The following commit has been merged in the master branch: commit fd0c42c4dea54335967c5a86f15fc064235a2797 Author: George Spelvin <lkml(a)sdf.org> Date: Sun Mar 8 09:44:59 2020 -0400 batman-adv: fix batadv_nc_random_weight_tq and change to pseudorandom numbers, as this is a traffic dithering operation that doesn't need crypto-grade. The previous code operated in 4 steps: 1. Generate a random byte 0 <= rand_tq <= 255 2. Multiply it by BATADV_TQ_MAX_VALUE - tq 3. Divide by 255 (= BATADV_TQ_MAX_VALUE) 4. Return BATADV_TQ_MAX_VALUE - rand_tq This would apperar to scale (BATADV_TQ_MAX_VALUE - tq) by a random value between 0/255 and 255/255. But! The intermediate value between steps 3 and 4 is stored in a u8 variable. So it's truncated, and most of the time, is less than 255, after which the division produces 0. Specifically, if tq is odd, the product is always even, and can never be 255. If tq is even, there's exactly one random byte value that will produce a product byte of 255. Thus, the return value is 255 (511/512 of the time) or 254 (1/512 of the time). If we assume that the truncation is a bug, and the code is meant to scale the input, a simpler way of looking at it is that it's returning a random value between tq and BATADV_TQ_MAX_VALUE, inclusive. Well, we have an optimized function for doing just that.

The following commit has been merged in the master branch: commit 6f91a3f7af4186099dd10fa530dd7e0d9c29747d Author: Xiyu Yang <xiyuyang19(a)fudan.edu.cn> Date: Mon Apr 20 13:37:20 2020 +0800 batman-adv: Fix refcnt leak in batadv_v_ogm_process batadv_v_ogm_process() invokes batadv_hardif_neigh_get(), which returns a reference of the neighbor object to "hardif_neigh" with increased refcount. When batadv_v_ogm_process() returns, "hardif_neigh" becomes invalid, so the refcount should be decreased to keep refcount balanced. The reference counting issue happens in one exception handling paths of batadv_v_ogm_process(). When batadv_v_ogm_orig_get() fails to get the orig node and returns NULL, the refcnt increased by batadv_hardif_neigh_get() is not decreased, causing a refcnt leak. Fix this issue by jumping to "out" label when batadv_v_ogm_orig_get() fails to get the orig node.
