2021-10-28RDMA/core: Fix missed initialization of rdma_hw_stats::lockMark Zhang
alloc_and_bind() creates a new rdma_hw_stats structure but misses initializing the mutex lock.

2021-10-28Merge branch 'mvpp2-phylink'David S. Miller
Russell King says: ==================== Convert mvpp2 to phylink supported_interfaces This patch series converts mvpp2 to use phylinks supported_interfaces bitmap to simplify the validate() implementation. The patches: 1) Add the supported interface modes the supported_interfaces bitmap. 2) Removes the checks for the interface type being supported from the validate callback 3) Removes the now unnecessary checks and call to phylink_helper_basex_speed() to support switching between 1000base-X and 2500base-X for SFPs 4) Cleans up the resulting validate() code. (3) becomes possible because when asking the MAC for its complete support, we walk all supported interfaces which will include 1000base-X and 2500base-X only if the comphy is present. ==================== Signed-off-by: David S.

2021-10-28powerpc/dcr: Use cmplwi instead of 3-argument cmpliMichael Ellerman
In dcr-low.S we use cmpli with three arguments, instead of four arguments as defined in the ISA: cmpli cr0,r3,1024 This appears to be a PPC440-ism, looking at the "PPC440x5 CPU Core User’s Manual" it shows cmpli having no L field, but implied to be 0 due to the core being 32-bit. It mentions that the ISA defines four arguments and recommends using cmplwi. It also corresponds to the old POWER instruction set, which had no L field there, a reserved bit instead. dcr-low.S is only built 32-bit, because it is only built when DCR_NATIVE=y, which is only selected by 40x and 44x. Looking at the generated code (with gcc/gas) we see cmplwi as expected. Although gas is happy with the 3-argument version when building for 32-bit, the LLVM assembler is not and errors out with: arch/powerpc/sysdev/dcr-low.S:27:10: error: invalid operand for instruction cmpli 0,%r3,1024; ... ^ Switch to the cmplwi extended opcode, which avoids any confusion when reading the ISA, fixes the issue with the LLVM assembler, and also means the code could be built 64-bit in future (though that's very unlikely).

2021-10-28KVM: PPC: Tick accounting should defer vtime accounting 'til after IRQ handlingLaurent Vivier
Commit 112665286d08 ("KVM: PPC: Book3S HV: Context tracking exit guest context before enabling irqs") moved guest_exit() into the interrupt protected area to avoid wrong context warning (or worse). The problem is that tick-based time accounting has not yet been updated at this point (because it depends on the timer interrupt firing), so the guest time gets incorrectly accounted to system time. To fix the problem, follow the x86 fix in commit 160457140187 ("Defer vtime accounting 'til after IRQ handling"), and allow host IRQs to run before accounting the guest exit time. In the case vtime accounting is enabled, this is not required because TB is used directly for accounting. Before this patch, with CONFIG_TICK_CPU_ACCOUNTING=y in the host and a guest running a kernel compile, the 'guest' fields of /proc/stat are stuck at zero. With the patch they can be observed increasing roughly as expected.

2021-10-28bpf, tests: Add module parameter test_suite to test_bpf moduleTiezhu Yang
After commit 9298e63eafea ("bpf/tests: Add exhaustive tests of ALU operand magnitudes"), when modprobe test_bpf.ko with JIT on mips64, there exists segment fault due to the following reason: [...] ALU64_MOV_X: all register value magnitudes jited:1 Break instruction in kernel code[#1] [...] It seems that the related JIT implementations of some test cases in test_bpf() have problems. At this moment, I do not care about the segment fault while I just want to verify the test cases of tail calls. Based on the above background and motivation, add the following module parameter test_suite to the test_bpf.ko: test_suite=<string>: only the specified test suite will be run, the string can be "test_bpf", "test_tail_calls" or "test_skb_segment". If test_suite is not specified, but test_id, test_name or test_range is specified, set 'test_bpf' as the default test suite. This is useful to only test the corresponding test suite when specifying the valid test_suite string. Any invalid test suite will result in -EINVAL being returned and no tests being run. If the test_suite is not specified or specified as empty string, it does not change the current logic, all of the test cases will be run. Here are some test results: # dmesg -c # modprobe test_bpf # dmesg | grep Summary test_bpf: Summary: 1009 PASSED, 0 FAILED, [0/997 JIT'ed] test_bpf: test_tail_calls: Summary: 8 PASSED, 0 FAILED, [0/8 JIT'ed] test_bpf: test_skb_segment: Summary: 2 PASSED, 0 FAILED # rmmod test_bpf # dmesg -c # modprobe test_bpf test_suite=test_bpf # dmesg | tail -1 test_bpf: Summary: 1009 PASSED, 0 FAILED, [0/997 JIT'ed] # rmmod test_bpf # dmesg -c # modprobe test_bpf test_suite=test_tail_calls # dmesg test_bpf: #0 Tail call leaf jited:0 21 PASS [...] test_bpf: #7 Tail call error path, index out of range jited:0 32 PASS test_bpf: test_tail_calls: Summary: 8 PASSED, 0 FAILED, [0/8 JIT'ed] # rmmod test_bpf # dmesg -c # modprobe test_bpf test_suite=test_skb_segment # dmesg test_bpf: #0 gso_with_rx_frags PASS test_bpf: #1 gso_linear_no_head_frag PASS test_bpf: test_skb_segment: Summary: 2 PASSED, 0 FAILED # rmmod test_bpf # dmesg -c # modprobe test_bpf test_id=1 # dmesg test_bpf: test_bpf: set 'test_bpf' as the default test_suite. test_bpf: #1 TXA jited:0 54 51 50 PASS test_bpf: Summary: 1 PASSED, 0 FAILED, [0/1 JIT'ed] # rmmod test_bpf # dmesg -c # modprobe test_bpf test_suite=test_bpf test_name=TXA # dmesg test_bpf: #1 TXA jited:0 54 50 51 PASS test_bpf: Summary: 1 PASSED, 0 FAILED, [0/1 JIT'ed] # rmmod test_bpf # dmesg -c # modprobe test_bpf test_suite=test_tail_calls test_range=6,7 # dmesg test_bpf: #6 Tail call error path, NULL target jited:0 41 PASS test_bpf: #7 Tail call error path, index out of range jited:0 32 PASS test_bpf: test_tail_calls: Summary: 2 PASSED, 0 FAILED, [0/2 JIT'ed] # rmmod test_bpf # dmesg -c # modprobe test_bpf test_suite=test_skb_segment test_id=1 # dmesg test_bpf: #1 gso_linear_no_head_frag PASS test_bpf: test_skb_segment: Summary: 1 PASSED, 0 FAILED By the way, the above segment fault has been fixed in the latest bpf-next tree which contains the mips64 JIT rework.

2021-10-28platform/surface: aggregator_registry: Add initial support for Surface Pro 8Maximilian Luz
Add preliminary support for the Surface Pro 8 to the Surface Aggregator registry. This includes battery/charger status and platform profile support. In contrast to earlier Surface Pro generations, the keyboard cover is now also connected via the Surface Aggregator Module (whereas it was previously connected via USB or HID-over-I2C). To properly support the HID devices of that cover, however, more changes regarding hot-removal of Surface Aggregator client devices as well as a new device hub driver are required. We will address those things in a follow-up series, so do not add any HID device IDs just yet.

2021-10-28iwlwifi: mvm: extend session protection on associationJohannes Berg
When we receive an association response, a significant amount of time might have passed since we sent the corresponding association request (mac80211 will wait up to 500ms for the TX and then 100ms for the response after ACK was received). But the time event is touched only when we send the assoc request, so it might not have much time remaining, more easily causing the (dreaded) No beacon heard and the session protection is over already... message. Refactor iwl_mvm_mac_mgd_prepare_tx() and split out a new function iwl_mvm_protect_assoc(), and call it on successful association to extend the time event to the minimum time if necessary.
