2024-06-26scsi: mpi3mr: HDB allocation and posting for hardware and firmware buffersRanjan Kumar4-1/+790
To be able to debug controller problems it is beneficial to allocate and configure system/host memory buffers which can be used to capture hardware and firmware diagnostic information. Add functions required to allocate and post firmware and hardware diagnostic buffers to the controller and to set up automatic diagnostic capture triggers. Captures will be triggered under the following circumstances: 1. Firmware is in FAULT state. 2. Admin commands time out. 3. Controller reset caused due to I/O timeout Reported-by: kernel test robot <[email protected]> Closes: https://lore.kernel.org/oe-kbuild-all/[email protected]/ Co-developed-by: Sathya Prakash <[email protected]> Signed-off-by: Sathya Prakash <[email protected]> Signed-off-by: Ranjan Kumar <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Martin K.

2024-06-26scsi: lpfc: Fix a possible null pointer dereferenceHuai-Yuan Liu1-0/+5
In function lpfc_xcvr_data_show, the memory allocation with kmalloc might fail, thereby making rdp_context a null pointer. In the following context and functions that use this pointer, there are dereferencing operations, leading to null pointer dereference. To fix this issue, a null pointer check should be added. If it is null, use scnprintf to notify the user and return len.

2024-06-27wifi: rtl8xxxu: 8188f: Limit TX power indexMartin Kaistra1-0/+15
TX power index is read from the efuse on init, the values get written to the TX power registers when the channel gets switched. When the chip has not yet been calibrated, the efuse values are 0xFF, which on some boards leads to USB timeouts for reading/writing registers after the first frames have been sent. The vendor driver (v5.11.5-1) checks for these invalid values and sets default values instead. Implement something similar in rtl8188fu_parse_efuse().

DPK is short for digital pre-distortion calibration. It can adjusts digital waveform according to PA linear characteristics dynamically to enhance TX EVM for high power. Do this calibration when we are going to run on AP channel. To prevent power offset out of boundary, it monitors thermal and set proper boundary to register.

TSSI is transmitter signal strength indication, which is a close-loop hardware circuit to feedback actual transmitting power as a reference for next transmission. It does full calibration when we are going to connect an AP. When switching bands or channels for scanning or some reasons, reset hardware status to prevent use wrong power value feedback from previous transmission. It also loads tables of compensation values reflecting current temperature into registers according to channel and band group to transmit packets with expected power.

2024-06-27KVM: arm64: Honor trap routing for TCR2_EL1Marc Zyngier1-0/+13
TCR2_EL1 handling is missing the handling of its trap configuration: - HCRX_EL2.TCR2En must be handled in conjunction with HCR_EL2.{TVM,TRVM} - HFG{R,W}TR_EL2.TCR_EL1 does apply to TCR2_EL1 as well Without these two controls being implemented, it is impossible to correctly route TCR2_EL1 traps.

2024-06-27KVM: arm64: Make PIR{,E0}_EL1 save/restore conditional on FEAT_TCRXMarc Zyngier1-10/+14
As per the architecture, if FEAT_S1PIE is implemented, then FEAT_TCRX must be implemented as well. Take advantage of this to avoid checking for S1PIE when TCRX isn't implemented.

2024-06-27KVM: arm64: Make TCR2_EL1 save/restore dependent on the VM featuresMarc Zyngier1-2/+13
As for other registers, save/restore of TCR2_EL1 should be gated on the feature being actually present. In the case of a nVHE hypervisor, it is perfectly fine to leave the host value in the register, as HCRX_EL2.TCREn==0 imposes that TCR2_EL1 is treated as 0.

2024-06-27KVM: arm64: Get rid of HCRX_GUEST_FLAGSMarc Zyngier2-2/+7
HCRX_GUEST_FLAGS gives random KVM hackers the impression that they can stuff bits in this macro and unconditionally enable features in the guest. In general, this is wrong (we have been there with FEAT_MOPS, and again with FEAT_TCRX). Document that HCRX_EL2.SMPME is an exception rather than the rule, and get rid of HCRX_GUEST_FLAGS.

We currently blindly enable TCR2_EL1 use in a guest, irrespective of the feature set.

2024-06-27netfilter: nf_tables: fully validate NFT_DATA_VALUE on store to data registersPablo Neira Ayuso3-5/+11
register store validation for NFT_DATA_VALUE is conditional, however, the datatype is always either NFT_DATA_VALUE or NFT_DATA_VERDICT. This only requires a new helper function to infer the register type from the set datatype so this conditional check can be removed. Otherwise, pointer to chain object can be leaked through the registers.
