Pull networking fixes from David Miller: 1) Make sure SKB control block is in the proper state during IPSEC ESP-in-TCP encapsulation. From Sabrina Dubroca. 2) Various kinds of attributes were not being cloned properly when we build new xfrm_state objects from existing ones. Fix from Antony Antony. 3) Make sure to keep BTF sections, from Tony Ambardar. 4) TX DMA channels need proper locking in lantiq driver, from Hauke Mehrtens. 5) Honour route MTU during forwarding, always. From Maciej Żenczykowski. 6) Fix races in kTLS which can result in crashes, from Rohit Maheshwari. 7) Skip TCP DSACKs with rediculous sequence ranges, from Priyaranjan Jha. 8) Use correct address family in xfrm state lookups, from Herbert Xu. 9) A bridge FDB flush should not clear out user managed fdb entries with the ext_learn flag set, from Nikolay Aleksandrov. 10) Fix nested locking of netdev address lists, from Taehee Yoo. 11) Fix handling of 32-bit DATA_FIN values in mptcp, from Mat Martineau. 12) Fix r8169 data corruptions on RTL8402 chips, from Heiner Kallweit. 13) Don't free command entries in mlx5 while comp handler could still be running, from Eran Ben Elisha. 14) Error flow of request_irq() in mlx5 is busted, due to an off by one we try to free and IRQ never allocated. From Maor Gottlieb. 15) Fix leak when dumping netlink policies, from Johannes Berg. 16) Sendpage cannot be performed when a page is a slab page, or the page count is < 1. Some subsystems such as nvme were doing so. Create a "sendpage_ok()" helper and use it as needed, from Coly Li. 17) Don't leak request socket when using syncookes with mptcp, from Paolo Abeni. * git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (111 commits) net/core: check length before updating Ethertype in skb_mpls_{push,pop} net: mvneta: fix double free of txq->buf net_sched: check error pointer in tcf_dump_walker() net: team: fix memory leak in __team_options_register net: typhoon: Fix a typo Typoon --> Typhoon net: hinic: fix DEVLINK build errors net: stmmac: Modify configuration method of EEE timers tcp: fix syn cookied MPTCP request socket leak libceph: use sendpage_ok() in ceph_tcp_sendpage() scsi: libiscsi: use sendpage_ok() in iscsi_tcp_segment_map() drbd: code cleanup by using sendpage_ok() to check page for kernel_sendpage() tcp: use sendpage_ok() to detect misused .sendpage nvme-tcp: check page by sendpage_ok() before calling kernel_sendpage() net: add WARN_ONCE in kernel_sendpage() for improper zero-copy send net: introduce helper sendpage_ok() in include/linux/net.h net: usb: pegasus: Proper error handing when setting pegasus' MAC address net: core: document two new elements of struct net_device netlink: fix policy dump leak net/mlx5e: Fix race condition on nhe->n pointer in neigh update net/mlx5e: Fix VLAN create flow ...

2020-10-04hwmon: Add hwmon driver for Intel MAX 10 BMCXu Yilun2-0/+79
This patch adds hwmon functionality for Intel MAX 10 BMC chip. This BMC chip connects to a set of sensor chips to monitor current, voltage, thermal and power of different components on board. The BMC firmware is responsible for sensor data sampling and recording in shared registers. Host driver reads the sensor data from these shared registers and exposes them to users as hwmon interfaces.

Add a compatible string for the SynQuacer TPM to the binding for a TPM exposed via a memory mapped TIS frame. The MMIO window behaves slightly differently on this hardware, so it requires its own identifier.

2020-09-30media: hist-v4l2.rst: remove :c:`type` from structs and enumsMauro Carvalho Chehab1-128/+101
Using struct|enum :c:`type` here sounds a bad idea, as it may be documenting data types that were already removed. Also, it makes the file harder to read. As automarkup.py should be able to handle those cases, let's just get rid of the markup. While not required by automarkup, in order to make easier for grep, both type and names are now at the same line. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-09-30media: hist-v4l2.rst: remove struct duplicationMauro Carvalho Chehab1-7/+5
There are several places there where struct was used twice, on multiple lines, like: struct struct ``v4l2_zoomcap`` That's probably done during the DocBook to ReSt conversion. Probably the cases where "struct struct" were at the same line was addressed back then, but the multi-line cases are still there. Get rid of them.

2020-09-30media: cec-core.rst: fix warnings with Sphinx 3.0+Mauro Carvalho Chehab1-36/+26
The new C domain code on Sphinx 3 is a lot more pedantic. It only accepts real functions declared as c:function. So, declarations like this are not valid: .. c:function:: int (*adap_enable)(struct cec_adapter *adap, bool enable); Also, no blank lines are allowed after ".. c:function:", and continuation lines should be like: .. c:function: int (void foo, \ int bar); Change the logic there, in order to avoid lots of warnings when built with Sphinx 3.x.

There are several :c:type: definitions there, in order to do cross-references with the driver's documentation. Those are broken when docs are built with Sphinx 3.x, as it would require :c:struct: instead. For Sphinx < 3.x, the automarkup.py extension is able to do the replacement already, and a future improvement on it should make it also work with Sphinx 3.x. So, get rid of the usage of the :c:type: macro there. Reviewed-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
