[PATCH 1/6] net/hinic: Fix the driver does not report an error when setting MAC fails
by Yang Yingliang 22 Oct '20

22 Oct '20

From: Chiqijun <chiqijun(a)huawei.com> driver inclusion category: bugfix bugzilla: 4472 ----------------------------------------------------------------------- When using the ip link command to configure the MAC for the VF in the PF, the status 4 will be returned when the MAC is set on the VF; when the PF driver receives the status 4 returned by the firmwre, the MAC setting failed and an error should be reported.

[PATCH 01/20] nvme-rdma: remove redundant reference between ib_device and tagset
by Yang Yingliang 22 Oct '20

22 Oct '20

From: Max Gurtovoy <maxg(a)mellanox.com> mainline inclusion from mainline-v5.2-rc1 commit 87fd125344d68adf7699ec7396aa9f905ce79a80 category: bugfix bugzilla: NA CVE: NA Link: https://gitee.com/openeuler/kernel/issues/I1WGZE ------------------------------------------------- In the past, before adding f41725bb ("nvme-rdma: Use mr pool") commit, we needed a reference on the ib_device as long as the tagset was alive, as the MRs in the request structures needed a valid ib_device. Now, we allocate/deallocate MR pool per QP and consume on demand. Also remove nvme_rdma_free_tagset function and use blk_mq_free_tag_set instead, as it unneeded anymore. This commit also fixes a memory leakage and possible segmentation fault. When configuring the system with NIC teaming (aka bonding), we use 1 network interface to create an HA connection to the target side. In case one connection breaks down, nvme-rdma driver will get notification from rdma-cm layer that underlying address was change and will start error recovery process. During this process, we'll reconnect to the target via the second interface in the bond without destroying the tagset. This will cause a leakage of the initial rdma device (ndev) and miscount in the reference count of the new created rdma device (new ndev). In the final destruction (or in another error flow), we'll get a warning dump from the ib_dealloc_pd that we still have inflight MR's related to that pd. This happens becasue of the miscount of the reference tag of the rdma device and causing access violation to it's elements (some queues are not destroyed yet).

[PATCH] perf/core: Fix race in the perf_mmap_close() function
by Yang Yingliang 16 Oct '20

16 Oct '20

From: Jiri Olsa <jolsa(a)redhat.com> mainline inclusion from mainline-v5.10 commit f91072ed1b7283b13ca57fcfbece5a3b92726143 category: bugfix bugzilla: NA CVE: CVE-2020-14351 -------------------------------- There's a possible race in perf_mmap_close() when checking ring buffer's mmap_count refcount value. The problem is that the mmap_count check is not atomic because we call atomic_dec() and atomic_read() separately. perf_mmap_close: ... atomic_dec(&rb->mmap_count); ... if (atomic_read(&rb->mmap_count)) goto out_put; <ring buffer detach> free_uid out_put: ring_buffer_put(rb); /* could be last */ The race can happen when we have two (or more) events sharing same ring buffer and they go through atomic_dec() and then they both see 0 as refcount value later in atomic_read(). Then both will go on and execute code which is meant to be run just once. The code that detaches ring buffer is probably fine to be executed more than once, but the problem is in calling free_uid(), which will later on demonstrate in related crashes and refcount warnings, like: refcount_t: addition on 0; use-after-free. ...

[PATCH] geneve: add transport ports in route lookup for geneve
by Yang Yingliang 15 Oct '20

15 Oct '20

From: Mark Gray <mark.d.gray(a)redhat.com> stable inclusion from linux-4.19.148 commit c797110d97c48054d1491251fd713900ff51615c CVE: CVE-2020-25645 -------------------------------- [ Upstream commit 34beb21594519ce64a55a498c2fe7d567bc1ca20 ] This patch adds transport ports information for route lookup so that IPsec can select Geneve tunnel traffic to do encryption. This is needed for OVS/OVN IPsec with encrypted Geneve tunnels. This can be tested by configuring a host-host VPN using an IKE daemon and specifying port numbers. For example, for an Openswan-type configuration, the following parameters should be configured on both hosts and IPsec set up as-per normal: $ cat /etc/ipsec.conf conn in ... left=$IP1 right=$IP2 ... leftprotoport=udp/6081 rightprotoport=udp ... conn out ... left=$IP1 right=$IP2 ... leftprotoport=udp rightprotoport=udp/6081 ... The tunnel can then be setup using "ip" on both hosts (but changing the relevant IP addresses): $ ip link add tun type geneve id 1000 remote $IP2 $ ip addr add 192.168.0.1/24 dev tun $ ip link set tun up This can then be tested by pinging from $IP1: $ ping 192.168.0.2 Without this patch the traffic is unencrypted on the wire.
