However, the fix in this commit is wrong: the MODULE_DEVICE_TABLE(of, ....) is in the core part of the driver, not the I2C part. Therefore, automatic module loading based on module.alias, based on matching with the DT compatible string, loads the core part of the driver, but not the I2C part. And threfore, the i2c_driver is not registered, and the codec is not known to the system, nor matched with a DT node with the corresponding compatible string. In order to fix that, we move the MODULE_DEVICE_TABLE(of, ...) into the I2C part of the driver. The cs42l51_of_match[] array is also moved as well, as it is not possible to have this definition in one file, and the MODULE_DEVICE_TABLE(of, ...) invocation in another file, due to how MODULE_DEVICE_TABLE works. Thanks to this commit, the I2C part of the driver now properly autoloads, and thanks to its dependency on the core part, the core part gets autoloaded as well, resulting in a functional sound card without having to manually load kernel modules.

[PATCH v3] ceph: defer stopping the mdsc delayed_work

[PATCH 4.14] net/sched: cls_u32: Fix reference counter leak leading to overflow

by Rishabh Bhatnagar

From: Lee Jones <lee(a)kernel.org> Upstream commit 04c55383fa5689357bcdd2c8036725a55ed632bc. In the event of a failure in tcf_change_indev(), u32_set_parms() will immediately return without decrementing the recently incremented reference counter. If this happens enough times, the counter will rollover and the reference freed, leading to a double free which can be used to do 'bad things'. In order to prevent this, move the point of possible failure above the point where the reference counter is incremented. Also save any meaningful return values to be applied to the return data at the appropriate point in time. This issue was caught with KASAN.

[PATCH 4.14,5.4] net/sched: sch_qfq: account for stab overhead in qfq_enqueue

by Shaoying Xu

[ Upstream commit 3e337087c3b5805fe0b8a46ba622a962880b5d64 ] Lion says: ------- In the QFQ scheduler a similar issue to CVE-2023-31436 persists. Consider the following code in net/sched/sch_qfq.c: static int qfq_enqueue(struct sk_buff *skb, struct Qdisc *sch, struct sk_buff **to_free) { unsigned int len = qdisc_pkt_len(skb), gso_segs; // ... if (unlikely(cl->agg->lmax < len)) { pr_debug("qfq: increasing maxpkt from %u to %u for class %u", cl->agg->lmax, len, cl->common.classid); err = qfq_change_agg(sch, cl, cl->agg->class_weight, len); if (err) { cl->qstats.drops++; return qdisc_drop(skb, sch, to_free); } // ... } Similarly to CVE-2023-31436, "lmax" is increased without any bounds checks according to the packet length "len". Usually this would not impose a problem because packet sizes are naturally limited. This is however not the actual packet length, rather the "qdisc_pkt_len(skb)" which might apply size transformations according to "struct qdisc_size_table" as created by "qdisc_get_stab()" in net/sched/sch_api.c if the TCA_STAB option was set when modifying the qdisc. A user may choose virtually any size using such a table. As a result the same issue as in CVE-2023-31436 can occur, allowing heap out-of-bounds read / writes in the kmalloc-8192 cache. ------- We can create the issue with the following commands: tc qdisc add dev $DEV root handle 1: stab mtu 2048 tsize 512 mpu 0 \ overhead 999999999 linklayer ethernet qfq tc class add dev $DEV parent 1: classid 1:1 htb rate 6mbit burst 15k tc filter add dev $DEV parent 1: matchall classid 1:1 ping -I $DEV 1.1.1.2 This is caused by incorrectly assuming that qdisc_pkt_len() returns a length within the QFQ_MIN_LMAX < len < QFQ_MAX_LMAX.
