If ib_dma_mapping_error() returns non-zero value, ib_mad_post_receive_mads() will jump out of loops and return -ENOMEM without freeing mad_priv.

destroy_qp_common is called for flows where QP is already created by HW. While it is called from IB/core, the ibqp.* fields will be fully initialized, but it is not the case if this function is called during QP creation. Don't rely on ibqp fields as much as possible and initialize send_cq/recv_cq as temporal solution till all drivers will be converted to IB/core QP allocation scheme. refcount_t: underflow; use-after-free.

If a IMP reset caused by some hardware errors and hns RoCE driver reset occurred at the same time, there is a possiblity that the IMP will stop dealing with command and users can't use the hardware. The logs are as follows: hns3 0000:fd:00.1: cleaned 0, need to clean 1 hns3 0000:fd:00.1: firmware version query failed -11 hns3 0000:fd:00.1: Cmd queue init failed hns3 0000:fd:00.1: Upgrade reset level hns3 0000:fd:00.1: global reset interrupt The hns NIC driver divides the reset process into 3 status: initialization, hardware resetting and softwaring restting. RoCE driver gets reset status by interfaces provided by NIC driver and commands will not be sent to the IMP if the driver is in any above status. The main reason for this issue is that there is a time gap between status 1 and 2, if the RoCE driver sends commands to the IMP during this gap, the IMP will stop working because it is not ready. To eliminate the time gap, the hns NIC driver has added a new interface in commit a4de0228 ("net: hns3: provide .get_cmdq_stat interface for the client"), so RoCE driver can ensure that no commands will be sent during resetting.

Pull SafeSetID update from Micah Morton: "Add additional LSM hooks for SafeSetID SafeSetID is capable of making allow/deny decisions for set*uid calls on a system, and we want to add similar functionality for set*gid calls. The work to do that is not yet complete, so probably won't make it in for v5.8, but we are looking to get this simple patch in for v5.8 since we have it ready. We are planning on the rest of the work for extending the SafeSetID LSM being merged during the v5.9 merge window" * tag 'LSM-add-setgid-hook-5.8-author-fix' of git://github.com/micah-morton/linux: security: Add LSM hooks to set*gid syscalls

The SafeSetID LSM uses the security_task_fix_setuid hook to filter set*uid() syscalls according to its configured security policy. In preparation for adding analagous support in the LSM for set*gid() syscalls, we add the requisite hook here. Tested by putting print statements in the security_task_fix_setgid hook and seeing them get hit during kernel boot. Signed-off-by:

We found problems in invalidate page that don't seem to be fixable as regressions or without changing iomap code that would not affect other filesystems. There are four reverts in total, but three of them are followup cleanups needed to revert a43a67a2 cleanly. The result is the buffer head based implementation of direct io.

This reverts commit a43a67a2. This patch reverts the main part of switching direct io implementation to iomap infrastructure. There's a problem in invalidate page that couldn't be solved as regression in this development cycle. The problem occurs when buffered and direct io are mixed, and the ranges overlap. Although this is not recommended, filesystems implement measures or fallbacks to make it somehow work. In this case, fallback to buffered IO would be an option for btrfs (this already happens when direct io is done on compressed data), but the change would be needed in the iomap code, bringing new semantics to other filesystems. Another problem arises when again the buffered and direct ios are mixed, invalidation fails, then -EIO is set on the mapping and fsync will fail, though there's no real error. There have been discussions how to fix that, but revert seems to be the least intrusive option. Link: https://lore.kernel.org/linux-btrfs/20200528192103.xm45qoxqmkw7i5yl@fiona/Signed-off-by:

On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow unregistered mcast packets to pass. This happens, because ALE VLAN entries on these SoCs do not contain port masks for reg/unreg mcast packets, but instead store indexes of ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for reg/unreg mcast packets. This path was missed by commit 9d1f6447 ("net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled"). Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti(). Fixes: 9d1f6447 ("net: ethernet: ti: ale: fix seeing unreg mcast packets with promisc and allmulti disabled") Signed-off-by:
