2021-10-28mwifiex: fix division by zero in fw download pathJohan Hovold
Add the missing endpoint sanity checks to probe() to avoid division by zero in mwifiex_write_data_sync() in case a malicious device has broken descriptors (or when doing descriptor fuzz testing). Only add checks for the firmware-download boot stage, which require both command endpoints, for now. The driver looks like it will handle a missing endpoint during normal operation without oopsing, albeit not very gracefully as it will try to submit URBs to the default pipe and fail. 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")).

2021-10-28selftests/x86/amx: Add context switch testChang S. Bae
XSAVE state is thread-local. The kernel switches between thread state at context switch time. Generally, running a selftest for a while will naturally expose it to some context switching and and will test the XSAVE code. Instead of just hoping that the tests get context-switched at random times, force context-switches on purpose. Spawn off a few userspace threads and force context-switches between them. Ensure that the kernel correctly context switches each thread's unique AMX state. [ dhansen: bunches of cleanups ] Signed-off-by: Chang S.

2021-10-28selftests/x86/amx: Add test cases for AMX state managementChang S. Bae
AMX TILEDATA is a very large XSAVE feature. It could have caused nasty XSAVE buffer space waste in two places: * Signal stacks * Kernel task_struct->fpu buffers To avoid this waste, neither of these buffers have AMX state by default. The non-default features are called "dynamic" features. There is an arch_prctl(ARCH_REQ_XCOMP_PERM) which allows a task to declare that it wants to use AMX or other "dynamic" XSAVE features. This arch_prctl() ensures that sufficient sigaltstack space is available before it will succeed. It also expands the task_struct buffer. Functions of this test: * Test arch_prctl(ARCH_REQ_XCOMP_PERM). Ensure that it checks for proper sigaltstack sizing and that the sizing is enforced for future sigaltstack calls. * Ensure that ARCH_REQ_XCOMP_PERM is inherited across fork() * Ensure that TILEDATA use before the prctl() is fatal * Ensure that TILEDATA is cleared across fork() Note: Generally, compiler support is needed to do something with AMX. Instead, directly load AMX state from userspace with a plain XSAVE. Do not depend on the compiler. [ dhansen: bunches of cleanups ] Signed-off-by: Chang S.

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: remove session protection on disassocJohannes Berg
If we somehow get disassociated while still waiting for a beacon during connection, we can end up printing the No beacon heard and the session protection is over already... message even if we aren't really quite waiting for it anymore. Remove the time event, if it's running, when we get disassociated and don't need to wait for beacons anymore.

2021-10-28iwlwifi: mvm: fix WGDS table print in iwl_mvm_chub_update_mcc()Luca Coelho

2021-10-28iwlwifi: rename GEO_TX_POWER_LIMIT to PER_CHAIN_LIMIT_OFFSET_CMDLuca Coelho
When this code was implemented, there was no official FW API description yet, so a placeholder name was used (GEO_TX_POWER_LIMIT). But then the command became actually called PER_CHAIN_LIMIT_OFFSET_CMD. Rename the command (and change related comments) to PER_CHAIN_LIMIT_OFFSET_CMD to avoid confusion.

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.
