2021-10-28Drivers: hv: vmbus: Add SNP support for VMbus channel initiate messageTianyu Lan
The monitor pages in the CHANNELMSG_INITIATE_CONTACT msg are shared with host in Isolation VM and so it's necessary to use hvcall to set them visible to host. In Isolation VM with AMD SEV SNP, the access address should be in the extra space which is above shared gpa boundary. So remap these pages into the extra address(pa + shared_gpa_boundary). Introduce monitor_pages_original[] in the struct vmbus_connection to store monitor page virtual address returned by hv_alloc_hyperv_ zeroed_page() and free monitor page via monitor_pages_original in the vmbus_disconnect(). The monitor_pages[] is to used to access monitor page and it is initialized to be equal with monitor_pages_ original. The monitor_pages[] will be overridden in the isolation VM with va of extra address. Introduce monitor_pages_pa[] to store monitor pages' physical address and use it to populate pa in the initiate msg.

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.

2021-10-28iwlwifi: 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.

2021-10-28iwlwifi: mvm: d3: use internal data representationJohannes Berg
Trying to convert from one firmware data representation to the next version is getting tedious and error-prone, and doesn't lend itself well to new APIs being added. Additionally, the version 11 of the API as defined in the driver doesn't even exist in the firmware. Instead of converting to a newer firmware version of the data, convert to an internal representation. This takes a bit more space because the TKIP/AES counters etc. must be kept twice, their representation is different and we don't know which of the ones it is until later, but this is just a temporary use of memory, and the code is clearer this way.

2021-10-28iwlwifi: pcie: remove two duplicate PNJ device entriesJohannes Berg
Since PNJ and TH have the same ID (0x32), there are duplicate entries. Remove the duplicates with PNJ since PNJ is only the test device in the first place.

2021-10-28arm64: Select POSIX_CPU_TIMERS_TASK_WORKNicolas Saenz Julienne
With 6caa5812e2d1 ("KVM: arm64: Use generic KVM xfer to guest work function") all arm64 exit paths are properly equipped to handle the POSIX timers' task work. Deferring timer callbacks to thread context, not only limits the amount of time spent in hard interrupt context, but is a safer implementation[1], and will allow PREEMPT_RT setups to use KVM[2]. So let's enable POSIX_CPU_TIMERS_TASK_WORK on arm64.

2021-10-28ath6kl: fix division by zero in send pathJohan Hovold
Add the missing endpoint max-packet sanity check to probe() to avoid division by zero in ath10k_usb_hif_tx_sg() in case a malicious device has broken descriptors (or when doing descriptor fuzz testing). Note that USB core will reject URBs submitted for endpoints with zero wMaxPacketSize but that drivers doing packet-size calculations still need to handle this (cf. commit 2548288b4fb0 ("USB: Fix: Don't skip endpoint descriptors with maxpacket=0")).
