en_rx_am.c was deleted in 'net-next' but had a bug fixed in it in 'net'. The esp{4,6}_offload.c conflicts were overlapping changes. The 'out' label is removed so we just return ERR_PTR(-EINVAL) directly. Signed-off-by: David S. Miller <davem@davemloft.net>
2018-01-23x86/ftrace: Fix ORC unwinding from ftrace handlersJosh Poimboeuf
Steven Rostedt discovered that the ftrace stack tracer is broken when it's used with the ORC unwinder. The problem is that objtool is instructed by the Makefile to ignore the ftrace_64.S code, so it doesn't generate any ORC data for it. Fix it by making the asm code objtool-friendly: - Objtool doesn't like the fact that save_mcount_regs pushes RBP at the beginning, but it's never restored (directly, at least). So just skip the original RBP push, which is only needed for frame pointers anyway. - Annotate some functions as normal callable functions with ENTRY/ENDPROC. - Add an empty unwind hint to return_to_handler(). The return address isn't on the stack, so there's nothing ORC can do there. It will just punt in the unlikely case it tries to unwind from that code. With all that fixed, remove the OBJECT_FILES_NON_STANDARD Makefile annotation so objtool can read the file.

Add the functions for setting up and removing offloaded SAs (Security Associations) with the x540 hardware. We set up the callback structure but we don't yet set the hardware feature bit to be sure the XFRM service won't actually try to use us for an offload yet. The software tables are made up to mimic the hardware tables to make it easier to track what's in the hardware, and the SA table index is used for the XFRM offload handle. However, there is a hashing field in the Rx SA tracking that will be used to facilitate faster table searches in the Rx fast path.

Commit 111e6b45315c ("selftests/bpf: make test_verifier run most programs") enables tools/testing/selftests/bpf/test_verifier unit cases to run via bpf_prog_test_run command. With the latest code base, test_verifier had one test case failure: ... #473/p check deducing bounds from const, 2 FAIL retval 1 != 0 0: (b7) r0 = 1 1: (75) if r0 s>= 0x1 goto pc+1 R0=inv1 R1=ctx(id=0,off=0,imm=0) R10=fp0,call_-1 2: (95) exit from 1 to 3: R0=inv1 R1=ctx(id=0,off=0,imm=0) R10=fp0,call_-1 3: (d5) if r0 s<= 0x1 goto pc+1 R0=inv1 R1=ctx(id=0,off=0,imm=0) R10=fp0,call_-1 4: (95) exit from 3 to 5: R0=inv1 R1=ctx(id=0,off=0,imm=0) R10=fp0,call_-1 5: (1f) r1 -= r0 6: (95) exit processed 7 insns (limit 131072), stack depth 0 ... The test case does not set return value in the test structure and hence the return value from the prog run is assumed to be 0. However, the actual return value is 1. As a result, the test failed. The fix is to correctly set the return value in the test structure.

2018-01-23arm64: Run enable method for errata work arounds on late CPUsSuzuki K Poulose
When a CPU is brought up after we have finalised the system wide capabilities (i.e, features and errata), we make sure the new CPU doesn't need a new errata work around which has not been detected already. However we don't run enable() method on the new CPU for the errata work arounds already detected. This could cause the new CPU running without potential work arounds. It is upto the "enable()" method to decide if this CPU should do something about the errata.

2018-01-23bpf: fix incorrect kmalloc usage in lpm_trie MAP_GET_NEXT_KEY rcu regionYonghong Song
In commit b471f2f1de8b ("bpf: implement MAP_GET_NEXT_KEY command for LPM_TRIE map"), the implemented MAP_GET_NEXT_KEY callback function is guarded with rcu read lock. In the function body, "kmalloc(size, GFP_USER | __GFP_NOWARN)" is used which may sleep and violate rcu read lock region requirements. This patch fixed the issue by using GFP_ATOMIC instead to avoid blocking kmalloc. Tested with CONFIG_DEBUG_ATOMIC_SLEEP=y as suggested by Eric Dumazet.

Fix bug that causes _absolute_ rtsym sizes of > 8 bytes (as per symbol table) to result in incorrect space used during a TLV-based debug dump. Detail: The size calculation stage calculates the correct size (size of the rtsym address field == 8), while the dump uses the size in the table to calculate the TLV size to reserve. Symbols with size <= 8 are handled OK due to aligning sizes to 8, but including any absolute symbol with listed size > 8 leads to an ENOSPC error during the dump.

2018-01-23HID: quirks: Fix keyboard + touchpad on Toshiba Click Mini not workingHans de Goede
The Toshiba Click Mini uses an i2c attached keyboard/touchpad combo (single i2c_hid device for both) which has a vid:pid of 04F3:0401, which is also used by a bunch of Elan touchpads which are handled by the drivers/input/mouse/elan_i2c driver, but that driver deals with pure touchpads and does not work for a combo device such as the one on the Toshiba Click Mini. The combo on the Mini has an ACPI id of ELAN0800, which is not claimed by the elan_i2c driver, so check for that and if it is found do not ignore the device. This fixes the keyboard/touchpad combo on the Mini not working (although with the touchpad in mouse emulation mode).

2018-01-23SUNRPC: task_run_action should display tk_callbackChuck Lever
This shows up in every RPC: kworker/4:1-19772 [004] 3467.373443: rpc_task_run_action: task:4711@2 flags=0e81 state=0005 status=0 action=call_status kworker/4:1-19772 [004] 3467.373444: rpc_task_run_action: task:4711@2 flags=0e81 state=0005 status=0 action=call_status What's actually going on is that the first iteration of the RPC scheduler is invoking the function in tk_callback (in this case, xprt_timer), then invoking call_status on the next iteration. Feeding do_action, rather than tk_action, to the "task_run_action" trace point will now always display the correct FSM step.

2018-01-23xprtrdma: Fix "bytes registered" accountingChuck Lever
The contents of seg->mr_len changed when ->ro_map stopped returning the full chunk length in the first segment. Count the full length of each Write chunk, not the length of the first segment (which now can only be as large as a page). Fixes: 9d6b04097882 ("xprtrdma: Place registered MWs on a ...
