struct bfd_iovec
DESCRIPTION
The <<struct bfd_iovec>> contains the internal file I/O class.
Each <<BFD>> has an instance of this class and all file I/O is
routed through it (it is assumed that the instance implements
all methods listed below).
.struct bfd_iovec

. {* To avoid problems with macros, a "b" rather than "f"
. prefix is prepended to each method name. *}
. {* Attempt to read/write NBYTES on ABFD's IOSTREAM storing/fetching
. bytes starting at PTR. Return the number of bytes actually
. transfered (a read past end-of-file returns less than NBYTES),
. or -1 (setting <<bfd_error>>) if an error occurs. *}

Tidy bfdio to consistenly use containing archive Archive element IO is performed on the file of the containing archive, which leads to the BFD "where" field of archives and their elements being out of sync with the real file position. (We're talking traditional archives here, not thin archives.) The old bfd_seek code recognized this by not attempting to optimize away seeks for archives. However, there was other code that could return bogus results. For example, cache.c limits the number of open files by closing a file and remembering its state once the limit is reached. If bfd_tell is called on an archive element when the containing archive is closed, it will return an invalid file pointer. It's possible to have a valid "where" field for archives by always using and updating the containing archive BFD. That's what this patch does. Note that cache.c used to find the containing archive BFD anyway for the iostream, so we're not really doing extra work, just transferring it up to the correct abstraction level. The patch also gets rid of some hacks. bfd_tell was called when bfd_seek failed, in an attempt to correct "where". That's got to be papering over another problem, so that code has been removed. bfd_read also had an "optimiziation" to return early when the number of bytes was zero, and bfd_seek optimized calls that didn't move the file pointer. This was covering for a coff_slurp_line_table bug where IO was attempted on a pe-dll BFD without an iovec. * bfd.c (struct bfd): Update comment on "where" usage. * bfdio.c (bfd_bwrite, bfd_stat): Use and update "iovec", "iostream", and "where" from containing archive file. Return error on NULL iovec. (bfd_bread): Similarly, and return error attempted out of bounds archive element access. (bfd_tell, bfd_flush): Use and update "iovec", "iostream", and "where" from containing archive file. (bfd_seek): Likewise. Return error on NULL iovec. Don't attempt to optimize away seeks. Don't paper over errors by calling bfd_tell. (bfd_get_mtime): Call bfd_stat rather than iovec->bstat. (bfd_get_size): Likewise. (bfd_mmap): Operate on and use iovec of containing archive file.

Tidy bfdio to consistenly use containing archive Archive element IO is performed on the file of the containing archive, which leads to the BFD "where" field of archives and their elements being out of sync with the real file position. (We're talking traditional archives here, not thin archives.) The old bfd_seek code recognized this by not attempting to optimize away seeks for archives. However, there was other code that could return bogus results. For example, cache.c limits the number of open files by closing a file and remembering its state once the limit is reached. If bfd_tell is called on an archive element when the containing archive is closed, it will return an invalid file pointer. It's possible to have a valid "where" field for archives by always using and updating the containing archive BFD. That's what this patch does. Note that cache.c used to find the containing archive BFD anyway for the iostream, so we're not really doing extra work, just transferring it up to the correct abstraction level. The patch also gets rid of some hacks. bfd_tell was called when bfd_seek failed, in an attempt to correct "where". That's got to be papering over another problem, so that code has been removed. bfd_read also had an "optimiziation" to return early when the number of bytes was zero, and bfd_seek optimized calls that didn't move the file pointer. This was covering for a coff_slurp_line_table bug where IO was attempted on a pe-dll BFD without an iovec. * bfd.c (struct bfd): Update comment on "where" usage. * bfdio.c (bfd_bwrite, bfd_stat): Use and update "iovec", "iostream", and "where" from containing archive file.

FUNCTION
bfd_get_size
SYNOPSIS
ufile_ptr bfd_get_size (bfd *abfd);
DESCRIPTION
Return the file size (as read from file system) for the file
associated with BFD @var{abfd}.
The initial motivation for, and use of, this routine is not
so we can get the exact size of the object the BFD applies to, since
that might not be generally possible (archive members for example).
It would be ideal if someone could eventually modify
it so that such results were guaranteed.
Instead, we want to ask questions like "is this NNN byte sized
object I'm about to try read from file offset YYY reasonable?"
As as example of where we might do this, some object formats
use string tables for which the first <<sizeof (long)>> bytes of the
table contain the size of the table itself, including the size bytes.
If an application tries to read what it thinks is one of these
string tables, without some way to validate the size, and for
some reason the size is wrong (byte swapping error, wrong location
for the string table, etc.), the only clue is likely to be a read
error when it tries to read the table, or a "virtual memory
exhausted" error when it tries to allocate 15 bazillon bytes
of space for the 15 bazillon byte table it is about to read.
This function at least allows us to answer the question, "is the
size reasonable?".

That's got to be papering over another problem, so that code has been removed. bfd_read also had an "optimiziation" to return early when the number of bytes was zero, and bfd_seek optimized calls that didn't move the file pointer. This was covering for a coff_slurp_line_table bug where IO was attempted on a pe-dll BFD without an iovec. * bfd.c (struct bfd): Update comment on "where" usage. * bfdio.c (bfd_bwrite, bfd_stat): Use and update "iovec", "iostream", and "where" from containing archive file. Return error on NULL iovec. (bfd_bread): Similarly, and return error attempted out of bounds archive element access. (bfd_tell, bfd_flush): Use and update "iovec", "iostream", and "where" from containing archive file. (bfd_seek): Likewise. Return error on NULL iovec. Don't attempt to optimize away seeks. Don't paper over errors by calling bfd_tell. (bfd_get_mtime): Call bfd_stat rather than iovec->bstat. (bfd_get_size): Likewise. (bfd_mmap): Operate on and use iovec of containing archive file. Return error on NULL iovec. * cache.c (bfd_cache_lookup_worker): Abort if working on archive element bfd. (cache_bread_1): Delete bfd parameter, add FILE* parameter. Don't ignore zero byte reads. (cache_bread): Look up FILE* in cache here. Error on NULL lookup. (cache_bwrite): Rename "where" to "from". (cache_bmmap): Don't handle archive elements. * coffcode.h (coff_slurp_line_table): Exit early on zero lineno count. * bfd-in2.h: Regenerate.

Tidy bfdio to consistenly use containing archive Archive element IO is performed on the file of the containing archive, which leads to the BFD "where" field of archives and their elements being out of sync with the real file position. (We're talking traditional archives here, not thin archives.) The old bfd_seek code recognized this by not attempting to optimize away seeks for archives. However, there was other code that could return bogus results. For example, cache.c limits the number of open files by closing a file and remembering its state once the limit is reached. If bfd_tell is called on an archive element when the containing archive is closed, it will return an invalid file pointer. It's possible to have a valid "where" field for archives by always using and updating the containing archive BFD. That's what this patch does. Note that cache.c used to find the containing archive BFD anyway for the iostream, so we're not really doing extra work, just transferring it up to the correct abstraction level. The patch also gets rid of some hacks. bfd_tell was called when bfd_seek failed, in an attempt to correct "where". That's got to be papering over another problem, so that code has been removed. bfd_read also had an "optimiziation" to return early when the number of bytes was zero, and bfd_seek optimized calls that didn't move the file pointer. This was covering for a coff_slurp_line_table bug where IO was attempted on a pe-dll BFD without an iovec. * bfd.c (struct bfd): Update comment on "where" usage. * bfdio.c (bfd_bwrite, bfd_stat): Use and update "iovec", "iostream", and "where" from containing archive file.
