Commit 74bc9939 ("mlxsw: spectrum_router: Veto unsupported RIF MAC addresses") enabled the driver to veto router interface (RIF) MAC addresses that it cannot support. This check should only be performed for interfaces for which the driver actually configures a RIF. A VRF upper is not one of them, so ignore it. Without this patch it is not possible to set an IP address on the VRF device and use it as a loopback. Fixes: 74bc9939 ("mlxsw: spectrum_router: Veto unsupported RIF MAC addresses") Signed-off-by:

Restore SW_CRYPTO_CONTROL operation on AP_VLAN interfaces for unicast keys, the original override was intended to be done for group keys as those are treated specially by mac80211 and would always have been rejected. Now the situation is that AP_VLAN support must be enabled by the driver if it can support it (meaning it can support software crypto GTK TX). Thus, also simplify the code - if we get here with AP_VLAN and non- pairwise key, software crypto must be used (driver doesn't know about the interface) and can be used (driver must've advertised AP_VLAN if it also uses SW_CRYPTO_CONTROL).

There is logic to check that the RX/TPA consumer index is the expected index to work around a hardware problem. However, the potentially bad consumer index is first used to index into an array to reference an entry. This can potentially crash if the bad consumer index is beyond legal range.

Michael Zhivich says: ==================== ethtool: fix use of SPEED_UNKNOWN constant This patch series addresses 2 related issues: 1. ethtool_validate_speed() triggers a "signed-unsigned comparison" warning due to type difference of SPEED_UNKNOWN constant (int) and argument to ethtool_validate_speed (__u32). 2. some drivers use u16 storage for SPEED_UNKNOWN constant, resulting in value truncation and thus failure to test against SPEED_UNKNOWN correctly.

The poll condition should only check response_length, because reads should only be issued if there is data to read. The response_read flag only prevents double writes. The problem was that the write set the response_read to false, enqued a tpm job, and returned. Then application called poll which checked the response_read flag and returned EPOLLIN. Then the application called read, but got nothing. After all that the async_work kicked in. Added also mutex_lock around the poll check to prevent other possible race conditions.

There's a significant number of reports that re-enabling ASPM causes different issues, ranging from decreased performance to system not booting at all. This affects only a minority of users, but the number of affected users is big enough that we better switch off ASPM again. This will hurt notebook users who are not affected by the issues, they may see decreased battery runtime w/o ASPM. With the PCI core folks is being discussed to add generic sysfs attributes to control ASPM. Once this is in place brave enough users can re-enable ASPM on their system.

Currently there is no way for the driver to signal to mac80211 that it should schedule a TXQ even if there are no packets on the mac80211 part of that queue. This is problematic if the driver has an internal retry queue to deal with software A-MPDU retry. This patch changes the behavior of ieee80211_schedule_txq to always schedule the queue, as its only user (ath9k) seems to expect such behavior already: it calls this function on tx status and on powersave wakeup whenever its internal retry queue is not empty. Also add an extra argument to ieee80211_return_txq to get the same behavior. This fixes an issue on ath9k where tx queues with packets to retry (and no new packets in mac80211) would not get serviced.

When the mtu of a vrf device is set to 0, it would cause ping failed. So I think we should limit vrf mtu in a reasonable range to solve this problem. I set dev->min_mtu to IPV6_MIN_MTU, so it will works for both ipv4 and ipv6. And if dev->max_mtu still be 0 can be confusing, so I set dev->max_mtu to ETH_MAX_MTU. Here is the reproduce step: 1.Config vrf interface and set mtu to 0: 3: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master vrf1 state UP mode DEFAULT group default qlen 1000 link/ether 52:54:00:9e:dd:c1 brd ff:ff:ff:ff:ff:ff 2.Ping peer: 3: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel master vrf1 state UP group default qlen 1000 link/ether 52:54:00:9e:dd:c1 brd ff:ff:ff:ff:ff:ff inet 10.0.0.1/16 scope global enp4s0 valid_lft forever preferred_lft forever connect: Network is unreachable 3.Set mtu to default value, ping works: PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data. 64 bytes from 10.0.0.2: icmp_seq=1 ttl=64 time=1.88 ms Fixes: ad49bc63 ("net: vrf: remove MTU limits for vrf device") Signed-off-by:Miaohe Lin <linmiaohe@huawei.com> Reviewed-by:

The commit 510ded33 ("slab: implement slab_root_caches list") changes the name of the list node within "struct kmem_cache" from "list" to "root_caches_node", but leaks_show() still use the "list" which causes a crash when reading /proc/slab_allocators. You need to have CONFIG_SLAB=y and CONFIG_MEMCG=y to see the problem, because without MEMCG all slab caches are root caches, and the "list" node happens to be the right one.
