* s390/bpf: Implement bpf_jit_supports_kfunc_call()Ilya Leoshkevich2023-01-301-2/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement calling kernel functions from eBPF. In general, the eBPF ABI is fairly close to that of s390x, with one important difference: on s390x callers should sign-extend signed arguments. Handle that by using information returned by bpf_jit_find_kfunc_model(). Here is an example of how sign extensions works. Suppose we need to call the following function from BPF: ; long noinline bpf_kfunc_call_test4(signed char a, short b, int c, long d) 0000000000936a78 <bpf_kfunc_call_test4>: 936a78: c0 04 00 00 00 00 jgnop bpf_kfunc_call_test4 ; return (long)a + (long)b + (long)c + d; 936a7e: b9 08 00 45 agr %r4,%r5 936a82: b9 08 00 43 agr %r4,%r3 936a86: b9 08 00 24 agr %r2,%r4 936a8a: c0 f4 00 1e 3b 27 jg <__s390_indirect_jump_r14> As per the s390x ABI, bpf_kfunc_call_test4() has the right to assume that a, b and c are sign-extended by the caller, which results in using 64-bit additions (agr) without any additional conversions. Without sign extension we would have the following on the JITed code side: ; tmp = bpf_kfunc_call_test4(-3, -30, -200, -1000); ; 5: b4 10 00 00 ff ff ff fd w1 = -3 0x3ff7fdcdad4: llilf %r2,0xfffffffd ; 6: b4 20 00 00 ff ff ff e2 w2 = -30 0x3ff7fdcdada: llilf %r3,0xffffffe2 ; 7: b4 30 00 00 ff ff ff 38 w3 = -200 0x3ff7fdcdae0: llilf %r4,0xffffff38 ; 8: b7 40 00 00 ff ff fc 18 r4 = -1000 0x3ff7fdcdae6: lgfi %r5,-1000 0x3ff7fdcdaec: mvc 64(4,%r15),160(%r15) 0x3ff7fdcdaf2: lgrl %r1,bpf_kfunc_call_test4@GOT 0x3ff7fdcdaf8: brasl %r14,__s390_indirect_jump_r1 This first 3 llilfs are 32-bit loads, that need to be sign-extended to 64 bits. Note: at the moment bpf_jit_find_kfunc_model() does not seem to play nicely with XDP metadata functions: add_kfunc_call() adds an "abstract" bpf_*() version to kfunc_btf_tab, but then fixup_kfunc_call() puts the concrete version into insn->imm, which bpf_jit_find_kfunc_model() cannot find. But this seems to be a common code problem.

* s390/bpf: Implement arch_prepare_bpf_trampoline()Ilya Leoshkevich2023-01-301-22/+520
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | arch_prepare_bpf_trampoline() is used for direct attachment of eBPF programs to various places, bypassing kprobes. It's responsible for calling a number of eBPF programs before, instead and/or after whatever they are attached to. Add a s390x implementation, paying attention to the following: - Reuse the existing JIT infrastructure, where possible. - Like the existing JIT, prefer making multiple passes instead of backpatching. Currently 2 passes is enough. If literal pool is introduced, this needs to be raised to 3. However, at the moment adding literal pool only makes the code larger. If branch shortening is introduced, the number of passes needs to be increased even further. - Support both regular and ftrace calling conventions, depending on the trampoline flags. - Use expolines for indirect calls. - Handle the mismatch between the eBPF and the s390x ABIs. - Sign-extend fmod_ret return values. invoke_bpf_prog() produces about 120 bytes; it might be possible to slightly optimize this, but reaching 50 bytes, like on x86_64, looks unrealistic: just loading cookie, __bpf_prog_enter, bpf_func, insnsi and __bpf_prog_exit as literals already takes at least 5 * 12 = 60 bytes, and we can't use relative addressing for most of them. Therefore, lower BPF_MAX_TRAMP_LINKS on s390x.

* s390/bpf: Implement bpf_arch_text_poke()Ilya Leoshkevich2023-01-301-0/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | bpf_arch_text_poke() is used to hotpatch eBPF programs and trampolines. s390x has a very strict hotpatching restriction: the only thing that is allowed to be hotpatched is conditional branch mask. Take the same approach as commit de5012b41e5c ("s390/ftrace: implement hotpatching"): create a conditional jump to a "plt", which loads the target address from memory and jumps to it; then first patch this address, and then the mask. Trampolines (introduced in the next patch) respect the ftrace calling convention: the return address is in %r0, and %r1 is clobbered. With that in mind, bpf_arch_text_poke() does not differentiate between jumps and calls. However, there is a simple optimization for jumps (for the epilogue_ip case): if a jump already points to the destination, then there is no "plt" and we can just flip the mask. For simplicity, the "plt" template is defined in assembly, and its size is used to define C arrays. There doesn't seem to be a way to convey this size to C as a constant, so it's hardcoded and double-checked during runtime.

For unusable segments, vmx_segment_access_rights skips all attributes and sets them to 0. This means we zero out the DPL (Descriptor Privilege Level) for unusable entries. Unusable segments are - contrary to their name - usable in 64bit mode and are used by guests to for example create a linear map through the NULL selector. VMENTER checks if SS.DPL is correct depending on the CS segment type. For types 9 (Execute Only) and 11 (Execute Read), CS.DPL must be equal to SS.DPL [1]. We have seen real world guests setting CS to a usable segment with DPL=3 and SS to an unusable segment with DPL=3. Once we go through an sregs get/set cycle, SS.DPL turns to 0. This causes the virtual machine to crash reproducibly. This commit changes the attribute logic to always preserve attributes for unusable segments. According to [2] SS.DPL is always saved on VM exits, regardless of the unusable bit so user space applications should have saved the information on serialization correctly. [3] specifies that besides SS.DPL the rest of the attributes of the descriptors are undefined after VM entry if unusable bit is set. So, there should be no harm in setting them all to the previous state.

The opposite is done once the state is saved. This is all done by using the activate/deactivate irqdomain callbacks directly from the vgic code. Crutially, this is done without holding the irqdesc lock for the interrupts that represent the VPE. And these callbacks are changing the state of the irqdesc. What could possibly go wrong? If a doorbell fires while we are messing with the irqdesc state, it will acquire the lock and change the interrupt state concurrently. Since we don't hole the lock, curruption occurs in on the interrupt state. Oh well. While acquiring the lock would fix this (and this was Shanker's initial approach), this is still a layering violation we could do without. A better approach is actually to free the VPE interrupt, do what we have to do, and re-request it. It is more work, but this usually happens only once in the lifetime of the VM and we don't really care about this sort of overhead.

However, there are other potential users of the EFI runtime stack, such as the ACPI subsystem, which may invoke efi_call_virt_pointer() directly, and so any sync exceptions occurring in firmware during those calls are currently misidentified. So instead, let's check whether the stashed value of the thread stack pointer points into current's thread stack. This can only be the case if current was interrupted while running EFI runtime code. Note that this implies that we should clear the stashed value after switching back, to avoid false positives.

However the scheduler will still read these values and use them. The result is that the scheduler might perform unfair decisions based on stale values. This patch adds the step of setting the arch_freq_scale values for all cpus to the default (max) value SCHED_CAPACITY_SCALE, Once all cpus have the same arch_freq_scale value the scaling is meaningless.

Checking the allocation against the datasheet, it looks like there has been a mis-calcualation of the resource for the first memory region (0x0060090000..0x0070ffffff) which in the data-sheet for the fu740 (v1p2) is from 0x0060000000..0x007fffffff.

If compatible = "marvell,armadaxp-gpio", the reg property requires a second (address, size) pair, which points to the per-CPU interrupt registers <0x18800 0x30> / <0x18840 0x30>. Furthermore: Commit 5f79c651e81e explains very well, why the gpio-mvebu driver does not work reliably with per-CPU interrupts. Commit 988c8c0cd04d deprecates compatible = marvell,armadaxp-gpio for this reason.

The blamed commit is incorrect in the first place: If compatible = "marvell,armadaxp-gpio", the second (address, size) pair of the reg property must to point to the per-CPU interrupt registers <0x18800 0x30> / <0x18840 0x30>, and not to the blink enable registers <0x181c0 0x08> / <0x181c8 0x08>. But even fixing that leaves the GPIO interrupts broken on the Omnia. Furthermore: Commit 5f79c651e81e explains very well, why the gpio-mvebu driver does not work reliably with per-CPU interrupts. Commit 988c8c0cd04d deprecates compatible = marvell,armadaxp-gpio for this reason.

Issues where identified with the QMP PHY binding, that would prevent enablement of Displayport and it was decided not to support the old binding for the recently introduced SC8280XP, which broke USB. This adjusts the USB PHY nodes to the new binding. The reset signal for the first QMP PHY is corrected as well. The reserved memory map is updated on Xiaomi Mi 4C and Huawei Nexus 6P, to avoid instabilities caused by use of protected memory regions. The compatible for the MSM8992 TCSR mutex is corrected as well. Lastly SDHCI interconnects on SM8350 are corrected to match the providers #interconnect-cells. * tag 'qcom-arm64-fixes-for-6.2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: arm64: dts: qcom: msm8992-libra: Fix the memory map arm64: dts: qcom: msm8992: Don't use sfpb mutex arm64: dts: msm8994-angler: fix the memory map arm64: dts: qcom: sm8350: correct SDHCI interconnect arguments Revert "arm64: dts: qcom: sm8250: Disable the not yet supported cluster idle state" arm64: dts: msm8992-bullhead: add memory hole region arm64: dts: qcom: sc8280xp: fix USB-DP PHY nodes arm64: dts: qcom: sc8280xp: fix primary USB-DP PHY reset Link: https://lore.kernel.org/r/20230110213724.2183668-1-andersson@kernel.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

For mcbsp, the #ifdef check can simply be removed as the cpu_is_omapxxx() checks already achieve the same result, while in the io.c the easiest solution appears to be to merge the common map bits into each soc specific portion. This gets cleaned in a nicer way after omap7xx support gets dropped, as the remaining SoCs all have the exact same I/O map.
