target is a regular file, instead of doing binary searching. It also
fixes a couple of cases where a file descriptor is leaked in the
ext2fs_getsize() routine on error.

ext2fs_test_bit to take an unsigned int for the bit number. Negative
bit numbers were never allowed (and didn't make any sense), so this should
be a safe change. This is needed to allow safe use of block numbers
greater than or equal to 2**31.
The trouble is that it is modifying pointers in place, but doing so via
"void *" types which alias the pointers passed in (which are typically
pointers to a struct.) The inline ext2fs_resize_mem() code may update
the pointer, but the caller is not required to reload the old value it
may have cached in a register, according to the type aliasing rules.
This is causing the caller to dereference the old pointer when compiled
with -O2, resulting in reproducible SEGV, on at least one ia64
configuration.
The compiler *is* required to reload if it sees an update to a dereferenced
char value, though, as chars are defined to alias anything; and memcpy()
is defined to operate on chars. So using memcpy() to copy the pointer
values is guaranteed to force the caller to reload. This has been
verified to fix the problem in practice.

this suggested patch.

old library calls initialize_xxx_error_table, and another
library/application calls add_error_table() on the same
error table, and then calls remove_error_table().

programs, or if kernel believes that the process is not eligible to create
a core dump. In addition, if the libc has __secure_getenv(), use it so that
the libc can also do any additional limitations regarding when libraries can
trust environment variables (i.e., to integrate with systems like SELinux
and Posix capabilities).

a new inode we make sure that the extra information in the inode (any extra
fields in a large inode and any ea-in-inode information) is cleared. This
can happen when e2fsck creates a new root inode or a new lost+found directory,
or when the user uses the debugfs write, mknod, or mkdir commands. Otherwise,
the newly create inode could inherit garbage (or old EA information) from
a previously deleted inode.
