2023-10-06m68k: emu: Replace strlcpy() with strscpy()Azeem Shaikh1-3/+3
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). Direct replacement is safe here since return value of -errno is used to check for truncation instead of sizeof(dest).

Replace the (incorrect) external declarations by an inclusion of the appropriate header file. Semantically, the "src" parameters of the various fp_*() functions are constant. However, they cannot actually be const as most of these functions perform a normalization step first. As the fp_one constant passed to fp_add() is already normalized, it is safe to cast away its constness when making the function call.

On close, the newly created event dentry will get a "dput" without ever having a "dget" done for it.

The regressions arrived in the v6.5 dev cycle and missed the v6.6 merge window due to my personal absences this cycle. The most important fixes are for scenarios where the CXL subsystem fails to parse valid region configurations established by platform firmware. This is important because agreement between OS and BIOS on the CXL configuration is fundamental to implementing "OS native" error handling, i.e. address translation and component failure identification. Other important fixes are a driver load error when the BIOS lets the Linux PCI core handle AER events, but not CXL memory errors. The other fixex might have end user impact, but for now are only known to trigger in our test/emulation environment. Summary: - Fix multiple scenarios where platform firmware defined regions fail to be assembled by the CXL core. - Fix a spurious driver-load failure on platforms that enable OS native AER, but not OS native CXL error handling. - Fix a regression detecting "poison" commands when "security" commands are also defined. - Fix a cxl_test regression with the move to centralize CXL port register enumeration in the CXL core. - Miscellaneous small fixes and cleanups" * tag 'cxl-fixes-6.6-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: cxl/acpi: Annotate struct cxl_cxims_data with __counted_by cxl/port: Fix cxl_test register enumeration regression cxl/region: Refactor granularity select in cxl_port_setup_targets() cxl/region: Match auto-discovered region decoders by HPA range cxl/mbox: Fix CEL logic for poison and security commands cxl/pci: Replace host_bridge->native_aer with pcie_aer_is_native() PCI/AER: Export pcie_aer_is_native() cxl/pci: Fix appropriate checking for _OSC while handling CXL RAS registers
