[RFC][PATCH v2 4/7] bpf-lsm: Enforce return value limitations on security modules

by Roberto Sassu

From: Roberto Sassu <roberto.sassu(a)huawei.com> With the patch for the LSM infrastructure to redefine the LSM_HOOK() macro and to introduce the return value flags, it becomes straightforward for eBPF to leverage this information to enforce return values limitations on eBPF programs implementing security hooks. Update the bpf_lsm_hooks BTF ID set, by including the return value flags. Then, introduce bpf_lsm_is_ret_value_allowed(), which determines in which intervals the R0 register (which contains the return value) falls, and checks if the corresponding return value flag is set for those intervals. In addition, for the interval including zero, ensure that the hook is not inode_init_security, otherwise report that zero is not allowed. By LSM conventions, LSMs should return zero only if they set an xattr, which currently eBPF programs cannot do. Finally, expose the new function and add a call to it in the verifier.

[PATCH 02/12] dt-bindings: arm: msm: Fix register regions used for LLCC banks

by Manivannan Sadhasivam

Register regions of the LLCC banks are located at separate addresses. Currently, the binding just lists the LLCC0 base address and specifies the size to cover all banks. This is not the correct approach since, there are holes and other registers located in between. So let's specify the base address of each LLCC bank. It should be noted that the bank count differs for each SoC, so that also needs to be taken into account in the binding.

[PATCH 12/12] qcom: llcc/edac: Fix the base address used for accessing LLCC banks

by Manivannan Sadhasivam

The Qualcomm LLCC/EDAC drivers were using a fixed register stride for accessing the (Control and Status Registers) CSRs of each LLCC bank. This stride only works for some SoCs like SDM845 for which driver support was initially added. But the later SoCs use different register stride that vary between the banks with holes in-between. So it is not possible to use a single register stride for accessing the CSRs of each bank. By doing so could result in a crash. For fixing this issue, let's obtain the base address of each LLCC bank from devicetree and get rid of the fixed stride.

[PATCH 12/12] llcc/edac: Fix the base address used for accessing LLCC banks

by Manivannan Sadhasivam

The LLCC driver has been using a fixed register offset stride for accessing the CSRs of each LLCC bank. This offset only works for some SoCs like SDM845 for which driver support was initially added. But the later SoCs use different register stride that vary between the banks with holes in-between. So it is not possible to use a single register stride for accessing the CSRs of each bank. Hence, obtain the base address of each LLCC bank from devicetree and get rid of the fixed stride.

[PATCH 11/12] arm64: dts: qcom: sm6350: Fix the base addresses of LLCC banks

by Manivannan Sadhasivam

The LLCC block has several banks each with a different base address and holes in between. So it is not a correct approach to cover these banks with a single offset/size. Instead, the individual bank's base address needs to be specified in devicetree with the exact size. On SM6350, there is only one LLCC bank available. So let's just pass that as "llcc0_base".
