2022-05-20sfc/siena: Remove duplicate check on segmentsMartin Habets
Siena only supports software TSO.

2022-05-20selftests/bpf: Add missing trampoline program type to trampoline_count testYuntao Wang
Currently the trampoline_count test doesn't include any fmod_ret bpf programs, fix it to make the test cover all possible trampoline program types. Since fmod_ret bpf programs can't be attached to __set_task_comm function, as it's neither whitelisted for error injection nor a security hook, change it to bpf_modify_return_test.

2022-05-20Merge branch 'bpf: mptcp: Support for mptcp_sock'Andrii Nakryiko
Mat Martineau says: ==================== This patch set adds BPF access to mptcp_sock structures, along with associated self tests. You may recognize some of the code from earlier (https://lore.kernel.org/bpf/20200918121046.190240-6-nicolas.rybowski@tessares.net/) but it has been reworked quite a bit. v1 -> v2: Emit BTF type, add func_id checks in verifier.c and bpf_trace.c, remove build check for CONFIG_BPF_JIT, add selftest check for CONFIG_MPTCP, and add a patch to include CONFIG_IKCONFIG/CONFIG_IKCONFIG_PROC for the BPF self tests. v2 -> v3: Access sysctl through the filesystem to work around CI use of the more limited busybox sysctl command. v3 -> v4: Dropped special case kernel code for tcp_sock is_mptcp, use existing bpf_tcp_helpers.h, and add check for 'ip mptcp monitor' support. v4 -> v5: Use BPF test skeleton, more consistent use of ASSERT macros, drop some unnecessary parameters / checks, and use tracing to acquire MPTCP token.

2022-05-20selftests/bpf: Test bpf_skc_to_mptcp_sockGeliang Tang
This patch extends the MPTCP test base, to test the new helper bpf_skc_to_mptcp_sock(). Define struct mptcp_sock in bpf_tcp_helpers.h, use bpf_skc_to_mptcp_sock to get the msk socket in progs/mptcp_sock.c and store the infos in socket_storage_map. Get the infos from socket_storage_map in prog_tests/mptcp.c. Add a new function verify_msk() to verify the infos of MPTCP socket, and rename verify_sk() to verify_tsk() to verify TCP socket only. v2: Add CONFIG_MPTCP check for clearer error messages v4: - use ASSERT_* instead of CHECK_FAIL (Andrii) - drop bpf_mptcp_helpers.h (Andrii) v5: - some 'ASSERT_*' were replaced in the next commit by mistake. - Drop CONFIG_MPTCP (Martin) - Use ASSERT_EQ (Andrii) Signed-off-by: Geliang Tang <geliang.tang@suse.com> Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Acked-by: Matthieu Baerts <matthieu.baerts@tessares.net> Link: https://lore.kernel.org/bpf/20220519233016.105670-5-mathew.j.martineau@linux.intel.com
2022-05-20selftests/bpf: Add MPTCP test baseNicolas Rybowski
This patch adds a base for MPTCP specific tests. It is currently limited to the is_mptcp field in case of plain TCP connection because there is no easy way to get the subflow sk from a msk in userspace. This implies that we cannot lookup the sk_storage attached to the subflow sk in the sockops program. v4: - add copyright 2022 (Andrii) - use ASSERT_* instead of CHECK_FAIL (Andrii) - drop SEC("version") (Andrii) - use is_mptcp in tcp_sock, instead of bpf_tcp_sock (Martin & Andrii) v5: - Drop connect_to_mptcp_fd (Martin) - Use BPF test skeleton (Andrii) - Use ASSERT_EQ (Andrii) - Drop the 'msg' parameter of verify_sk Co-developed-by: Geliang Tang <geliang.tang@suse.com> Signed-off-by: Geliang Tang <geliang.tang@suse.com> Signed-off-by: Nicolas Rybowski <nicolas.rybowski@tessares.net> Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Acked-by: Matthieu Baerts <matthieu.baerts@tessares.net> Link: https://lore.kernel.org/bpf/20220519233016.105670-4-mathew.j.martineau@linux.intel.com

2022-05-20perf: Fix sys_perf_event_open() race against selfPeter Zijlstra
Norbert reported that it's possible to race sys_perf_event_open() such that the looser ends up in another context from the group leader, triggering many WARNs. The move_group case checks for races against itself, but the !move_group case doesn't, seemingly relying on the previous group_leader->ctx == ctx check. However, that check is racy due to not holding any locks at that time. Therefore, re-check the result after acquiring locks and bailing if they no longer match. Additionally, clarify the not_move_group case from the move_group-vs-move_group race.

2022-05-20hwmon: (pmbus/ltc2978) Add chip specific write_byte_dataMårten Lindahl
Several of the manuals for devices supported by this driver describes the need for a minimum wait time before the chip is ready to receive next command. This wait time is already implemented in the driver as a ltc_wait_ready function with a driver defined wait time of 100 ms, and is considered for specific devices before reading/writing data on the pmbus. Since this driver uses the default pmbus_regulator_ops for the enable/ disable/is_enabled functions we should add a driver specific callback for write_byte_data to prevent bypassing the wait time recommendations for the following devices: ltc3880/ltc3882/ltc3883/ltc3884/ltc3886/ ltc3887/ltc3889/ltm4664/ltm4675/ltm4676/ltm4677/ltm4678/ltm4680/ltm4686/ ltm4700/ltc7880.

We need to keep some more information about the current board than just the sensors set, and with more boards to add the dmi id array grows quickly. Our probe code is always the same so let's switch to a custom test code and a custom board info array. That allows us to omit board vendor string (ASUS uses two strings that differ in case) in the board info and use case-insensitive comparison, and also do not duplicate sensor definitions for such board variants as " (WI-FI)" when sensors are identical to the base variant. Also saves a quarter of the module size by replacing big dmi_system_id structs with smaller ones.

Instead of registering the hwmon device at probe time, use the existing "occ_active" sysfs file to control when the driver polls the OCC for sensor data and registers with hwmon. The reason for this change is that the SBE, which is the device by which the driver communicates with the OCC, cannot handle communications during certain system state transitions, resulting in unrecoverable system errors.

2022-05-20hwmon: (nct6775) Rearrange attr-group initializationZev Weiss
We now track the number of attribute groups in nct6775_data, as a measure to simplify handling differences in the set of enabled attribute groups between nct6775 drivers (platform & i2c). As a side effect, we also reduce the amount of IS_ERR()/PTR_ERR() boilerplate a bit.

2022-05-20hwmon: (nct6775) Convert register access to regmap APIZev Weiss
This replaces the nct6775_data->{read,write}_value function pointers with a regmap. The major difference is that the regmap access functions may fail, and hence require checking at each call site. While the existing WMI register-access code had potential failure paths, they were masked by the fact that the read_value() function returned the register value directly, and hence squashed errors undetectably by simply returning zero, and while the write_value() functions were capable of reporting errors, all callers ignored them. This improves the robustness of the existing code, and also prepares the driver for an i2c version to be added soon, for which register accesses are much more likely to actually fail. The conversion of the register-access call sites is largely mechanical (reading a register now returns the value via an out-param pointer, and returned errors must be checked for and propagated to callers), though the nct6775_write_fan_div() function is refactored slightly to avoid duplicating nearly identical (and now lengthier) code in each switch case.

2022-05-20hwmon: (dell-smm) Avoid unnecessary SMM calls during initArmin Wolf
When the driver tries to detect the fan multiplier during module initialisation, it issues one SMM call for each fan. Those SMM calls are however redundant and also try to query fans which may not be present. Fix that by detecting the fan multiplier during hwmon initialisation when no extra SMM calls are needed. Also dont assume the last nominal speed entry to be the biggest and instead check all entries.
