2023-12-01powerpc: Add PVN support for HeXin C2000 processorZhao Ke6-3/+23
HeXin Tech Co. has applied for a new PVN from the OpenPower Community for its new processor C2000. The OpenPower has assigned a new PVN and this newly assigned PVN is 0x0066, add pvr register related support for this PVN.

With NUMA=n and FA_DUMP=y or PRESERVE_FA_DUMP=y the build fails with: arch/powerpc/kernel/fadump.c:1739:22: error: no previous prototype for ‘arch_reserved_kernel_pages’ [-Werror=missing-prototypes] 1739 | unsigned long __init arch_reserved_kernel_pages(void) | ^~~~~~~~~~~~~~~~~~~~~~~~~~ The prototype for arch_reserved_kernel_pages() is in include/linux/mm.h, but it's guarded by __HAVE_ARCH_RESERVED_KERNEL_PAGES. The powerpc headers define __HAVE_ARCH_RESERVED_KERNEL_PAGES in asm/mmzone.h, which is not included into the generic headers when NUMA=n. Move the definition of __HAVE_ARCH_RESERVED_KERNEL_PAGES into asm/mmu.h which is included regardless of NUMA=n. Additionally the ifdef around __HAVE_ARCH_RESERVED_KERNEL_PAGES needs to also check for CONFIG_PRESERVE_FA_DUMP.

2023-11-28powerpc/rtas_pci: rename and properly expose config access APIsNathan Lynch3-15/+16
The rtas_read_config() and rtas_write_config() functions in kernel/rtas_pci.c have external linkage and two users in arch/powerpc: the rtas_pci code itself and the pseries platform's "enhanced error handling" (EEH) support code. The prototypes for these functions in asm/ppc-pci.h have until now been guarded by CONFIG_EEH since the only external caller is the pseries EEH code. However, this presumably has always generated warnings when built with !CONFIG_EEH and -Wmissing-prototypes: arch/powerpc/kernel/rtas_pci.c:46:5: error: no previous prototype for function 'rtas_read_config' [-Werror,-Wmissing-prototypes] 46 | int rtas_read_config(struct pci_dn *pdn, int where, int size, u32 *val) arch/powerpc/kernel/rtas_pci.c:98:5: error: no previous prototype for function 'rtas_write_config' [-Werror,-Wmissing-prototypes] 98 | int rtas_write_config(struct pci_dn *pdn, int where, int size, u32 val) The introduction of commit c6345dfa6e3e ("Makefile.extrawarn: turn on missing-prototypes globally") forces the issue. The efika and chrp platform code have (static) functions with the same names but different signatures. We may as well eliminate the potential for conflicts and confusion by renaming the globally visible versions as their prototypes get moved out of the CONFIG_EEH-guarded region; their current names are too generic anyway. Since they operate on objects of the type 'struct pci_dn *', give them the slightly more verbose prefix "rtas_pci_dn_" and fix up all the call sites.

2023-11-27powerpc/lib: Avoid array bounds warnings in vec opsMichael Ellerman1-2/+2
Building with GCC with -Warray-bounds enabled there are several warnings in sstep.c along the lines of: In function ‘do_byte_reverse’, inlined from ‘do_vec_load’ at arch/powerpc/lib/sstep.c:691:3, inlined from ‘emulate_loadstore’ at arch/powerpc/lib/sstep.c:3439:9: arch/powerpc/lib/sstep.c:289:23: error: array subscript 2 is outside array bounds of ‘u8[16]’ {aka ‘unsigned char[16]’} [-Werror=array-bounds=] 289 | up[2] = byterev_8(up[1]); | ~~~~~~^~~~~~~~~~~~~~~~~~ arch/powerpc/lib/sstep.c: In function ‘emulate_loadstore’: arch/powerpc/lib/sstep.c:681:11: note: at offset 16 into object ‘u’ of size 16 681 | } u = {}; | ^ do_byte_reverse() supports a size up to 32 bytes, but in these cases the caller is only passing a 16 byte buffer. In practice there is no bug, do_vec_load() is only called from the LOAD_VMX case in emulate_loadstore(). That in turn is only reached when analyse_instr() recognises VMX ops, and in all cases the size is no greater than 16: $ git grep -w LOAD_VMX arch/powerpc/lib/sstep.c arch/powerpc/lib/sstep.c: op->type = MKOP(LOAD_VMX, 0, 1); arch/powerpc/lib/sstep.c: op->type = MKOP(LOAD_VMX, 0, 2); arch/powerpc/lib/sstep.c: op->type = MKOP(LOAD_VMX, 0, 4); arch/powerpc/lib/sstep.c: op->type = MKOP(LOAD_VMX, 0, 16); Similarly for do_vec_store(). Although the warning is incorrect, the code would be safer if it clamped the size from the caller to the known size of the buffer. Do that using min_t().

2023-11-27powerpc: Make cpu_spec __ro_after_initMichael Ellerman1-2/+2
The cpu_spec is a struct holding various information about the CPU the kernel is executing on. It's populated early in boot and must not change after that. In particular the cpu_features and mmu_features hold the set of discovered CPU/MMU features and are used to set static keys for each feature, and do binary patching of assembly. So any change to the cpu_features/mmu_features later in boot will not be reflected in the state of the static keys or patched code. There is already logic to check that cpu_features/mmu_features don't change, see check_features() in feature-fixups.c. But as another layer of protection the entire cpu_spec should be read only after init, annotate it as such.

2023-11-18parisc: Replace strlcpy() with strscpy()Kees Cook1-1/+1
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]. Additionally, it returns the size of the source string, not the resulting size of the destination string. In an effort to remove strlcpy() completely[2], replace strlcpy() here with strscpy().
