SVN rev 210338 on 2010-07-21 10:25:02Z by kaiw
Perform additional checks when translating between file and memory
representations of ELF types.
The ELF(3) API allows applications to request a conversion that is
`in-place', i.e., with source and destinations data buffers being
the same. However, the file and memory sizes of ELF sections that
have additional internal structure, such as those of type `Elf_Note',
or `Elf_GNU_Hash_Header', can be determined only known after the
type-specific headers that comprise the first few words in these
sections are read and translated.
Pass in the size of destination buffer to type translation routines
in "libelf_convert.m4" and have these routines return an error code
if the translated data would not fit inside the destination buffer.
