(cherry picked from commit b6f2ff9363)
fix https://github.com/openssl/openssl/issues/25112
As defined in the C standard:
In all cases the argument is an int, the value of which shall
be representable as an unsigned char or shall equal the value
of the macro EOF. If the argument has any other value, the
behavior is undefined.
This is because they're designed to work with the int values returned
by getc or fgetc; they need extra work to handle a char value.
If EOF is -1 (as it almost always is), with 8-bit bytes, the allowed
inputs to the ctype.h functions are:
{-1, 0, 1, 2, 3, ..., 255}.
However, on platforms where char is signed, such as x86 with the
usual ABI, code like
char *p = ...;
... isspace(*p) ...
may pass in values in the range:
{-128, -127, -126, ..., -2, -1, 0, 1, ..., 127}.
This has two problems:
1. Inputs in the set {-128, -127, -126, ..., -2} are forbidden.
2. The non-EOF byte 0xff is conflated with the value EOF = -1, so
even though the input is not forbidden, it may give the wrong
answer.
Casting char inputs to unsigned char first works around this, by
mapping the (non-EOF character) range {-128, -127, ..., -1} to {128,
129, ..., 255}, leaving no collisions with EOF. So the above
fragment needs to be:
char *p = ...;
... isspace((unsigned char)*p) ...
This patch inserts unsigned char casts where necessary. Most of the
cases I changed, I compile-tested using -Wchar-subscripts -Werror on
NetBSD, which defines the ctype.h functions as macros so that they
trigger the warning when the argument has type char. The exceptions
are under #ifdef __VMS or #ifdef _WIN32. I left alone calls where
the input is int where the cast would obviously be wrong; and I left
alone calls where the input is already unsigned char so the cast is
unnecessary.

(cherry picked from commit c91f0ca958)
bind_afalg calls afalg_aes_cbc which allocates
cipher_handle->_hidden global object(s)
but if one of them fails due to out of memory,
the function bind_afalg relies on the engine destroy
method to be called. But that does not happen
because the dynamic engine object is not destroyed
in the usual way in dynamic_load in this case:
If the bind_engine function fails, there will be no
further calls into the shared object.

Byte swapping code incorrectly uses the number of AES rounds to swap expanded
AES key, while swapping only a single dword in a loop, resulting in swapped
key and partially swapped expanded keys, breaking AES encryption and
decryption on VIA Padlock hardware.
This commit correctly sets the number of swapping loops to be done.

Including e_os.h with a path from a header file doesn't work well on

Since we don't seem to be able to stop ourselves, the better move is
to move e_os.h to an include directory that's part of the inclusion
path given to the compiler.

Add a "where did this EVP_{CIPHER,MD} come from" flag: global, via fetch,
or via EVP_{CIPHER,MD}_meth_new. Update EVP_{CIPHER,MD}_free to handle all
three origins. The flag is deliberately right before some function pointers,
so that compile-time failures (int/pointer) will occur, as opposed to
taking a bit in the existing "flags" field. The "global variable" flag
is non-zero, so the default case of using OPENSSL_zalloc (for provider
ciphers), will do the right thing. Ref-counting is a no-op for
Make up_ref no-op for global MD and CIPHER objects

the deprecated function) and EVP_MD_CTX_get1_md(). Likewise, deprecate
EVP_CIPHER_CTX_cipher() in favor of EVP_CIPHER_CTX_get0_cipher(), and add
EVP_CIPHER_CTX_get1_CIPHER().

Also change some flags tests to explicit test == or != zero. E.g.,

if (!(flags & x)) --> if ((flags & x) == 0)
