2021-02-15net: bridge: fix br_vlan_filter_toggle stub when CONFIG_BRIDGE_VLAN_FILTERING=nVladimir Oltean
The prototype of br_vlan_filter_toggle was updated to include a netlink extack, but the stub definition wasn't, which results in a build error when CONFIG_BRIDGE_VLAN_FILTERING=n.

2021-02-15net: bridge: fix switchdev_port_attr_set stub when CONFIG_SWITCHDEV=nVladimir Oltean
The switchdev_port_attr_set function prototype was updated only for the case where CONFIG_SWITCHDEV=y|m, leaving a prototype mismatch with the stub definition for the disabled case. This results in a build error, so update that function too.

2021-02-15net: mscc: ocelot: avoid type promotion when calling ocelot_ifh_set_destVladimir Oltean
Smatch is confused by the fact that a 32-bit BIT(port) macro is passed as argument to the ocelot_ifh_set_dest function and warns: ocelot_xmit() warn: should '(((1))) << (dp->index)' be a 64 bit type? seville_xmit() warn: should '(((1))) << (dp->index)' be a 64 bit type? The destination port mask is copied into a 12-bit field of the packet, starting at bit offset 67 and ending at 56. So this DSA tagging protocol supports at most 12 bits, which is clearly less than 32. Attempting to send to a port number > 12 will cause the packing() call to truncate way before there will be 32-bit truncation due to type promotion of the BIT(port) argument towards u64. Therefore, smatch's fears that BIT(port) will do the wrong thing and cause unexpected truncation for "port" values >= 32 are unfounded. Nonetheless, let's silence the warning by explicitly passing an u64 value to ocelot_ifh_set_dest, such that the compiler does not need to do a questionable type promotion.

and ulds The Max imm data size in cxgb4 is not similar to the max imm data size in the chtls. This caused an mismatch in output of is_ofld_imm() of cxgb4 and chtls. So fixed this by keeping the max wreq size of imm data same in both chtls and cxgb4 as MAX_IMM_OFLD_TX_DATA_WR_LEN. As cxgb4's max imm. data value for ofld packets is changed to MAX_IMM_OFLD_TX_DATA_WR_LEN. Using the same in cxgbit also.

2021-02-15ASoC: soc-pcm: fix hwparams min/max init for dpcmKai Vehmanen
When runtime is initialized with dpcm_init_runtime_hw(), some of the min/max calculations assume that defaults are set. For example calculation of channel min/max values may be done using zero-initialized data and soc_pcm_hw_update_chan() will always return max-channels of 0 in this case. This will result in failure to open the PCM at all. Fix the issue by calling soc_pcm_hw_init() before calling any soc_pcm_hw_update_*() functions. Remove the conditional code on runtime->hw.formats as this field is anyways set in soc_pcm_hw_init().

2021-02-15thermal: ti-soc-thermal: Simplify polling with iopollTony Lindgren
We can use iopoll for checking the EOCZ (end of conversion) bit. And with this we now also want to handle the timeout errors properly. For omap3, we need about 1.2ms for the single mode sampling to wait for EOCZ down, so let's use 1.5ms timeout there. Waiting for sampling to start is faster and we can use 1ms timeout.

2021-02-15thermal: ti-soc-thermal: Fix stuck sensor with continuous mode for 4430Tony Lindgren
At least for 4430, trying to use the single conversion mode eventually hangs the thermal sensor. This can be quite easily seen with errors: thermal thermal_zone0: failed to read out thermal zone (-5) Also, trying to read the temperature shows a stuck value with: $ while true; do cat /sys/class/thermal/thermal_zone0/temp; done Where the temperature is not rising at all with the busy loop. Additionally, the EOCZ (end of conversion) bit is not rising on 4430 in single conversion mode while it works fine in continuous conversion mode. It is also possible that the hung temperature sensor can affect the thermal shutdown alert too. Let's fix the issue by adding TI_BANDGAP_FEATURE_CONT_MODE_ONLY flag and use it for 4430. Note that we also need to add udelay to for the EOCZ (end of conversion) bit polling as otherwise we have it time out too early on 4430. We'll be changing the loop to use iopoll in the following clean-up patch.

2021-02-15thermal: ti-soc-thermal: Skip pointless register access for dra7Tony Lindgren
On dra7, there is no Start of Conversion (SOC) register bit and we have an empty bgap_soc_mask in the configuration for the thermal driver. Let's not do pointless reads and writes with the empty mask. There's also no point waiting for End of Conversion bit (EOCZ) to go high on dra7. We only care about it going down, and are now mostly timing out waiting for EOCZ high while it has already gone down. When we add checking for the timeout errors in a later patch, waiting for EOCZ high would cause bogus time out errors.

2021-02-15netfilter: nftables: introduce table ownershipPablo Neira Ayuso
A userspace daemon like firewalld might need to monitor for netlink updates to detect its ruleset removal by the (global) flush ruleset command to ensure ruleset persistency. This adds extra complexity from userspace and, for some little time, the firewall policy is not in place. This patch adds the NFT_TABLE_F_OWNER flag which allows a userspace program to own the table that creates in exclusivity. Tables that are owned... - can only be updated and removed by the owner, non-owners hit EPERM if they try to update it or remove it. - are destroyed when the owner closes the netlink socket or the process is gone (implicit netlink socket closure). - are skipped by the global flush ruleset command. - are listed in the global ruleset. The userspace process that sets on the NFT_TABLE_F_OWNER flag need to leave open the netlink socket. A new NFTA_TABLE_OWNER netlink attribute specifies the netlink port ID to identify the owner from userspace. This patch also updates error reporting when an unknown table flag is specified to change it from EINVAL to EOPNOTSUPP given that EINVAL is usually reserved to report for malformed netlink messages to userspace.

2021-02-15svcrdma: Hold private mutex while invoking rdma_accept()Chuck Lever
RDMA core mutex locking was restructured by commit d114c6feedfe ("RDMA/cma: Add missing locking to rdma_accept()") [Aug 2020]. When lock debugging is enabled, the RPC/RDMA server trips over the new lockdep assertion in rdma_accept() because it doesn't call rdma_accept() from its CM event handler. As a temporary fix, have svc_rdma_accept() take the handler_mutex explicitly. In the meantime, let's consider how to restructure the RPC/RDMA transport to invoke rdma_accept() from the proper context. Calls to svc_rdma_accept() are serialized with calls to svc_rdma_free() by the generic RPC server layer.

2021-02-15nfsd: register pernet ops last, unregister firstJ. Bruce Fields
These pernet operations may depend on stuff set up or torn down in the module init/exit functions. And they may be called at any time in between. So it makes more sense for them to be the last to be registered in the init function, and the first to be unregistered in the exit function. In particular, without this, the drc slab is being destroyed before all the per-net drcs are shut down, resulting in an "Objects remaining in nfsd_drc on __kmem_cache_shutdown()" warning in exit_nfsd.
