Denys Vlasenko 16e72e9b30 powerpc: do not make the entire heap executable 
On 32-bit powerpc the ELF PLT sections of binaries (built with
--bss-plt, or with a toolchain which defaults to it) look like this:

  [17] .sbss             NOBITS          0002aff8 01aff8 000014 00  WA  0   0  4
  [18] .plt              NOBITS          0002b00c 01aff8 000084 00 WAX  0   0  4
  [19] .bss              NOBITS          0002b090 01aff8 0000a4 00  WA  0   0  4

Which results in an ELF load header:

  Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
  LOAD           0x019c70 0x00029c70 0x00029c70 0x01388 0x014c4 RWE 0x10000

This is all correct, the load region containing the PLT is marked as
executable.  Note that the PLT starts at 0002b00c but the file mapping
ends at 0002aff8, so the PLT falls in the 0 fill section described by
the load header, and after a page boundary.

Unfortunately the generic ELF loader ignores the X bit in the load
headers when it creates the 0 filled non-file backed mappings.  It
assumes all of these mappings are RW BSS sections, which is not the case
for PPC.

gcc/ld has an option (--secure-plt) to not do this, this is said to
incur a small performance penalty.

Currently, to support 32-bit binaries with PLT in BSS kernel maps
*entire brk area* with executable rights for all binaries, even
--secure-plt ones.

Stop doing that.

Teach the ELF loader to check the X bit in the relevant load header and
create 0 filled anonymous mappings that are executable if the load
header requests that.

Test program showing the difference in /proc/$PID/maps:

int main() {
	char buf[16*1024];
	char *p = malloc(123); /* make "[heap]" mapping appear */
	int fd = open("/proc/self/maps", O_RDONLY);
	int len = read(fd, buf, sizeof(buf));
	write(1, buf, len);
	printf("%p\n", p);
	return 0;
}

Compiled using: gcc -mbss-plt -m32 -Os test.c -otest
