2020-12-11nl80211: add common API to configure SAR power limitationsCarl Huang
NL80211_CMD_SET_SAR_SPECS is added to configure SAR from user space. NL80211_ATTR_SAR_SPEC is used to pass the SAR power specification when used with NL80211_CMD_SET_SAR_SPECS. Wireless driver needs to register SAR type, supported frequency ranges to wiphy, so user space can query it. The index in frequency range is used to specify which sub band the power limitation applies to. The SAR type is for compatibility, so later other SAR mechanism can be implemented without breaking the user space SAR applications. Normal process is user space queries the SAR capability, and gets the index of supported frequency ranges and associates the power limitation with this index and sends to kernel. Here is an example of message send to kernel: 8c 00 00 00 08 00 01 00 00 00 00 00 38 00 2b 81 08 00 01 00 00 00 00 00 2c 00 02 80 14 00 00 80 08 00 02 00 00 00 00 00 08 00 01 00 38 00 00 00 14 00 01 80 08 00 02 00 01 00 00 00 08 00 01 00 48 00 00 00 NL80211_CMD_SET_SAR_SPECS: 0x8c NL80211_ATTR_WIPHY: 0x01(phy idx is 0) NL80211_ATTR_SAR_SPEC: 0x812b (NLA_NESTED) NL80211_SAR_ATTR_TYPE: 0x00 (NL80211_SAR_TYPE_POWER) NL80211_SAR_ATTR_SPECS: 0x8002 (NLA_NESTED) freq range 0 power: 0x38 in 0.25dbm unit (14dbm) freq range 1 power: 0x48 in 0.25dbm unit (18dbm) Signed-off-by: Carl Huang <cjhuang@codeaurora.org> Reviewed-by: Brian Norris <briannorris@chromium.org> Reviewed-by: Abhishek Kumar <kuabhs@chromium.org> Link: https://lore.kernel.org/r/20201203103728.3034-2-cjhuang@codeaurora.org [minor edits, NLA parse cleanups] Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2020-12-11mac80211: don't filter out beacons once we start CSAEmmanuel Grumbach
I hit a bug in which we started a CSA with an action frame, but the AP changed its mind and didn't change the beacon. The CSA wasn't cancelled and we lost the connection. The beacons were ignored because they never changed: they never contained any CSA IE. Because they never changed, the CRC of the beacon didn't change either which made us ignore the beacons instead of processing them. Now what happens is: 1) beacon has CRC X and it is valid. No CSA IE in the beacon 2) as long as beacon's CRC X, don't process their IEs 3) rx action frame with CSA 4) invalidate the beacon's CRC 5) rx beacon, CRC is still X, but now it is invalid 6) process the beacon, detect there is no CSA IE 7) abort CSA Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Link: https://lore.kernel.org/r/iwlwifi.20201206145305.83470b8407e6.I739b907598001362744692744be15335436b8351@changeid Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2020-12-11mac80211: don't set set TDLS STA bandwidth wider than possibleJohannes Berg
When we set up a TDLS station, we set sta->sta.bandwidth solely based on the capabilities, because the "what's the current bandwidth" check is bypassed and only applied for other types of stations. This leads to the unfortunate scenario that the sta->sta.bandwidth is 160 MHz if both stations support it, but we never actually configure this bandwidth unless the AP is already using 160 MHz; even for wider bandwidth support we only go up to 80 MHz (at least right now.) For iwlwifi, this can also lead to firmware asserts, telling us that we've configured the TX rates for a higher bandwidth than is actually available due to the PHY configuration. For non-TDLS, we check against the interface's requested bandwidth, but we explicitly skip this check for TDLS to cope with the wider BW case. Change this to (a) still limit to the TDLS peer's own chandef, which gets factored into the overall PHY configuration we request from the driver, and (b) limit it to when the TDLS peer is authorized, because it's only factored into the channel context in this case.

2020-12-11nl80211: validate key indexes for cfg80211_registered_deviceAnant Thazhemadam
syzbot discovered a bug in which an OOB access was being made because an unsuitable key_idx value was wrongly considered to be acceptable while deleting a key in nl80211_del_key(). Since we don't know the cipher at the time of deletion, if cfg80211_validate_key_settings() were to be called directly in nl80211_del_key(), even valid keys would be wrongly determined invalid, and deletion wouldn't occur correctly. For this reason, a new function - cfg80211_valid_key_idx(), has been created, to determine if the key_idx value provided is valid or not. cfg80211_valid_key_idx() is directly called in 2 places - nl80211_del_key(), and cfg80211_validate_key_settings().

2020-12-11rfkill: add a reason to the HW rfkill stateEmmanuel Grumbach
The WLAN device may exist yet not be usable. This can happen when the WLAN device is controllable by both the host and some platform internal component. We need some arbritration that is vendor specific, but when the device is not available for the host, we need to reflect this state towards the user space. Add a reason field to the rfkill object (and event) so that userspace can know why the device is in rfkill: because some other platform component currently owns the device, or because the actual hw rfkill signal is asserted. Capable userspace can now determine the reason for the rfkill and possibly do some negotiation on a side band channel using a proprietary protocol to gain ownership on the device in case the device is owned by some other component. When the host gains ownership on the device, the kernel can remove the RFKILL_HARD_BLOCK_NOT_OWNER reason and the hw rfkill state will be off. Then, the userspace can bring the device up and start normal operation. The rfkill_event structure is enlarged to include the additional byte, it is now 9 bytes long. Old user space will ask to read only 8 bytes so that the kernel can know not to feed them with more data. When the user space writes 8 bytes, new kernels will just read what is present in the file descriptor. This new byte is read only from the userspace standpoint anyway. If a new user space uses an old kernel, it'll ask to read 9 bytes but will get only 8, and it'll know that it didn't get the new state. When it'll write 9 bytes, the kernel will again ignore this new byte which is read only from the userspace standpoint.

2020-12-10selftests/bpf: Silence ima_setup.sh when not running in verbose mode.KP Singh
Currently, ima_setup.sh spews outputs from commands like mkfs and dd on the terminal without taking into account the verbosity level of the test framework. Update test_progs to set the environment variable SELFTESTS_VERBOSE=1 when a verbose output is requested. This environment variable is then used by ima_setup.sh (and can be used by other similar scripts) to obey the verbosity level of the test harness without needing to re-implement command line options for verbosity. In "silent" mode, the script saves the output to a temporary file, the contents of which are echoed back to stderr when the script encounters an error.

2020-12-10selftests/bpf: Drop the need for LLVM's llcAndrew Delgadillo
LLC is meant for compiler development and debugging. Consequently, it exposes many low level options about its backend. To avoid future bugs introduced by using the raw LLC tool, use clang directly so that all appropriate options are passed to the back end. Additionally, simplify the Makefile by removing the CLANG_NATIVE_BPF_BUILD_RULE as it is not being use, stop passing dwarfris attr since elfutils/libdw now supports the bpf backend (which should work with any recent pahole), and stop passing alu32 since -mcpu=v3 implies alu32.

2020-12-10selftests/bpf: fix bpf_testmod.ko recompilation logicAndrii Nakryiko
bpf_testmod.ko build rule declared dependency on VMLINUX_BTF, but the variable itself was initialized after the rule was declared, which often caused bpf_testmod.ko to not be re-compiled. Fix by moving VMLINUX_BTF determination sooner. Also enforce bpf_testmod.ko recompilation when we detect that vmlinux image changed by removing bpf_testmod/bpf_testmod.ko. This is necessary to generate correct module's split BTF. Without it, Kbuild's module build logic might determine that nothing changed on the kernel side and thus bpf_testmod.ko shouldn't be rebuilt, so won't re-generate module BTF, which often leads to module's BTF with wrong string offsets against vmlinux BTF. Removing .ko file forces Kbuild to re-build the module.
