2014-06-11dump: simplify get_len_buf_out()Laszlo Ersek
We can (and should) rely on the fact that s->flag_compress is exactly one of DUMP_DH_COMPRESSED_ZLIB, DUMP_DH_COMPRESSED_LZO, and DUMP_DH_COMPRESSED_SNAPPY. This is ensured by the QMP schema and dump_init() in combination.

2014-06-11dump: select header bitness based on ELF class, not ELF architectureLaszlo Ersek
The specific ELF architecture (d_machine) carries Too Much Information (TM) for deciding between create_header32() and create_header64(), use "d_class" instead (ELFCLASS32 vs. ELFCLASS64). This change adapts write_dump_header() to write_elf_loads(), dump_begin() etc. that also rely on the ELF class of the target for bitness selection. Considering the current targets that support dumping, cpu_get_dump_info() works as follows: - target-s390x/arch_dump.c: (EM_S390, ELFCLASS64) only - target-ppc/arch_dump.c (EM_PPC64, ELFCLASS64) only - target-i386/arch_dump.c: sets (EM_X86_64, ELFCLASS64) vs. (EM_386, ELFCLASS32) keying off the same Long Mode Active flag. Hence no observable change.

2014-06-11dump: eliminate DumpState.page_size ("guest's page size")Laszlo Ersek
Use TARGET_PAGE_SIZE and ~TARGET_PAGE_MASK instead. "DumpState.page_size" has type "size_t", whereas TARGET_PAGE_SIZE has type "int". TARGET_PAGE_MASK is of type "int" and has negative value. The patch affects the implicit type conversions as follows: - create_header32() and create_header64(): assigned to "block_size", which has type "uint32_t". No change. - get_next_page(): "block->target_start", "block->target_end" and "addr" have type "hwaddr" (uint64_t). Before the patch, - if "size_t" was "uint64_t", then no additional conversion was done as part of the usual arithmetic conversions, - If "size_t" was "uint32_t", then it was widened to uint64_t as part of the usual arithmetic conversions, for the remainder and addition operators. After the patch, - "~TARGET_PAGE_MASK" expands to ~~((1 << TARGET_PAGE_BITS) - 1). It has type "int" and positive value (only least significant bits set). That's converted (widened) to "uint64_t" for the bit-ands. No visible change. - The same holds for the (addr + TARGET_PAGE_SIZE) addition. - write_dump_pages(): - TARGET_PAGE_SIZE passed as argument to a bunch of functions that all have prototypes. No change. - When incrementing "offset_data" (of type "off_t"): given that we never build for ILP32_OFF32 (see "-D_FILE_OFFSET_BITS=64" in configure), "off_t" is always "int64_t", and we only need to consider: - ILP32_OFFBIG: "size_t" is "uint32_t". - before: int64_t += uint32_t. Page size converted to int64_t for the addition. - after: int64_t += int32_t. No change. - LP64_OFF64: "size_t" is "uint64_t". - before: int64_t += uint64_t. Offset converted to uint64_t for the addition, then the uint64_t result is converted to int64_t for storage. - after: int64_t += int32_t. Same as the ILP32_OFFBIG/after case. No visible change. - (size_out < s->page_size) comparisons, and (size_out = s->page_size) assignment: - before: "size_out" is of type "size_t", no implicit conversion for either operator. - after: TARGET_PAGE_SIZE (of type "int" and positive value) is converted to "size_t" (for the relop because the latter is one of "uint32_t" and "uint64_t"). No visible change. - dump_init(): - DIV_ROUND_UP(DIV_ROUND_UP(s->max_mapnr, CHAR_BIT), s->page_size): The innermost "DumpState.max_mapnr" field has type uint64_t, which propagates through all implicit conversions at hand: #define DIV_ROUND_UP(n,d) (((n) + (d) - 1) / (d)) regardless of the page size macro argument's type. In the outer macro replacement, the page size is converted from uint32_t and int32_t alike to uint64_t. - (tmp * s->page_size) multiplication: "tmp" has size "uint64_t"; the RHS is converted to that type from uint32_t and int32_t just the same if it's not uint64_t to begin with.

2014-06-11dump: eliminate DumpState.page_shift ("guest's page shift")Laszlo Ersek
Just use TARGET_PAGE_BITS. "DumpState.page_shift" used to have type "uint32_t", while the replacement TARGET_PAGE_BITS has type "int". Since "DumpState.page_shift" was only used as bit shift counts in the paddr_to_pfn() and pfn_to_paddr() macros, this is safe.

2014-06-11dump: simplify write_start_flat_header()Laszlo Ersek
Currently, the function - defines and populates an auto variable of type MakedumpfileHeader - allocates and zeroes a buffer of size MAX_SIZE_MDF_HEADER (4096) - copies the former into the latter (covering an initial portion of the latter) Fill in the MakedumpfileHeader structure in its final place (the alignment is OK because the structure lives at the address returned by g_malloc0()).

2014-06-11dump: fill in the flat header signature more pleasingly to the eyeLaszlo Ersek
The "mh.signature" array field has size 16, and is zeroed by the preceding memset(). MAKEDUMPFILE_SIGNATURE expands to a string literal with string length 12 (size 13). There's no need to measure the length of MAKEDUMPFILE_SIGNATURE at runtime, nor for the extra zero-filling of "mh.signature" with strncpy(). Use memcpy() with MIN(sizeof, sizeof) for robustness (which is an integer constant expression, evaluable at compile time.)
