Dipayaan Roy 95084f1883 net: mana: Fix crash from unvalidated SHM offset read from BAR0 during FLR ... During Function Level Reset recovery, the MANA driver reads hardware BAR0 registers that may temporarily contain garbage values. The SHM (Shared Memory) offset read from GDMA_REG_SHM_OFFSET is used to compute gc->shm_base, which is later dereferenced via readl() in mana_smc_poll_register(). If the hardware returns an unaligned or out-of-range value, the driver must not blindly use it, as this would propagate the hardware error into a kernel crash. The following crash was observed on an arm64 Hyper-V guest running kernel 6.17.0-3013-azure during VF reset recovery triggered by HWC timeout.

From the crash signature x20 = ffff8000a200001b, this address ends in 0x1b which is not 4-byte aligned, so the 'ldr w1, [x20]' instruction (readl) triggers the arm64 alignment fault (FSC = 0x21). The root cause is in mana_gd_init_vf_regs(), which computes: gc->shm_base = gc->bar0_va + mana_gd_r64(gc, GDMA_REG_SHM_OFFSET); The offset is used without any validation. The same problem exists in mana_gd_init_pf_regs() for sriov_base_off and sriov_shm_off. Fix this by validating all offsets before use: - VF: check shm_off is within BAR0, properly aligned to 4 bytes (readl requirement), and leaves room for the full 256-bit (32-byte) SMC aperture. - PF: check sriov_base_off is within BAR0, aligned to 8 bytes (readq requirement), and leaves room to safely read the sriov_shm_off register at sriov_base_off + GDMA_PF_REG_SHM_OFF. Then check sriov_shm_off leaves room for the full SMC aperture. All arithmetic uses subtraction rather than addition to avoid integer overflow on garbage values. Define SMC_APERTURE_SIZE (32 bytes, derived from the 256-bit aperture width) Return -EPROTO on invalid values. The existing recovery path in mana_serv_reset() already handles -EPROTO by falling through to PCI device rescan, giving the hardware another chance to present valid register values after reset.
