SEC1 descriptor is a bit different to SEC2+ descriptor. talitos_submit() will have to copy hdr field into hdr1 field and send the descriptor starting at hdr1 up to next_desc. For SEC2, it remains unchanged and next_desc is just ignored. Signed-off-by:

talitos descriptor is slightly different for SEC1 and SEC2+, so lets the helper function that fills the descriptor take into account the type of SEC. Signed-off-by:

We add a new feature in the features field, to mark compatible "fsl,sec1.0" We also define a helper function called has_ftr_sec1() to help functions quickly determine if they are running on SEC1 or SEC2+. When only SEC1 or SEC2 is compiled in, has_ftr_sec1() return trivial corresponding value. If both are compiled in, feature field is checked. Signed-off-by:

This patch enhances the talitos_desc struct with fields for SEC1. SEC1 has only one header field, and has a 'next_desc' field in addition. This mixed descriptor will continue to fit SEC2, and for SEC1 we will recopy hdr value into hdr1 value in talitos_submit() Signed-off-by:

The buffer uses for temporary data must be cleared entirely. In AES192 the used buffer is drbg_statelen(drbg) + drbg_blocklen(drbg) as documented in the comment above drbg_ctr_df. This patch ensures that the temp buffer is completely wiped. Signed-off-by:

Commit 9c521a20 ("crypto: api - remove instance when test failed") tried to grab a module reference count before the module was even set. Worse, it then goes on to free the module reference count after it is set so you quickly end up with a negative module reference count which prevents people from using any instances belonging to that module. This patch moves the module initialisation before the reference count. Reported-by:

The macro BITMAP_LAST_WORD_MASK can be implemented without a conditional, which will generally lead to slightly better generated code (221 bytes saved for allmodconfig-GCOV_KERNEL, ~2k with GCOV_KERNEL). As a small bonus, this also ensures that the nbits parameter is expanded exactly once. In BITMAP_FIRST_WORD_MASK, if start is signed gcc is technically allowed to assume it is positive (or divisible by BITS_PER_LONG), and hence just do the simple mask. It doesn't seem to use this, and even on an architecture like x86 where the shift only depends on the lower 5 or 6 bits, and these bits are not affected by the signedness of the expression, gcc still generates code to compute the C99 mandated value of start % BITS_PER_LONG. So just use a mask explicitly, also for consistency with BITMAP_LAST_WORD_MASK. Signed-off-by:

The current semantics of string_escape_mem are inadequate for one of its current users, vsnprintf(). If that is to honour its contract, it must know how much space would be needed for the entire escaped buffer, and string_escape_mem provides no way of obtaining that (short of allocating a large enough buffer (~4 times input string) to let it play with, and that's definitely a big no-no inside vsnprintf). So change the semantics for string_escape_mem to be more snprintf-like: Return the size of the output that would be generated if the destination buffer was big enough, but of course still only write to the part of dst it is allowed to, and (contrary to snprintf) don't do '\0'-termination. It is then up to the caller to detect whether output was truncated and to append a '\0' if desired. Also, we must output partial escape sequences, otherwise a call such as snprintf(buf, 3, "%1pE", "\123") would cause printf to write a \0 to buf[2] but leaving buf[0] and buf[1] with whatever they previously contained. This also fixes a bug in the escaped_string() helper function, which used to unconditionally pass a length of "end-buf" to string_escape_mem(); since the latter doesn't check osz for being insanely large, it would happily write to dst. For example, kasprintf(GFP_KERNEL, "something and then %pE", ...); is an easy way to trigger an oops. In test-string_helpers.c, the -ENOMEM test is replaced with testing for getting the expected return value even if the buffer is too small. We also ensure that nothing is written (by relying on a NULL pointer deref) if the output size is 0 by passing NULL - this has to work for kasprintf("%pE") to work. In net/sunrpc/cache.c, I think qword_add still has the same semantics. Someone should definitely double-check this. In fs/proc/array.c, I made the minimum possible change, but longer-term it should stop poking around in seq_file internals.

When printf is given the format specifier %pE, it needs a way of obtaining the total output size that would be generated if the buffer was large enough, and string_escape_mem doesn't easily provide that. This is a refactorization of string_escape_mem in preparation of changing its external API to provide that information. The somewhat ugly early returns and subsequent seemingly redundant conditionals are to make the following patch touch as little as possible in string_helpers.c while still preserving the current behaviour of never outputting partial escape sequences. That behaviour must also change for %pE to work as one expects from every other printf specifier. Signed-off-by:

The helper hex_string() is broken in two ways. First, it doesn't increment buf regardless of whether there is room to print, so callers such as kasprintf() that try to probe the correct storage to allocate will get a too small return value. But even worse, kasprintf() (and likely anyone else trying to find the size of the result) pass NULL for buf and 0 for size, so we also have end == NULL. But this means that the end-1 in hex_string() is (char*)-1, so buf < end-1 is true and we get a NULL pointer deref. I double-checked this with a trivial kernel module that just did a kasprintf(GFP_KERNEL, "%14ph", "CrashBoomBang"). Nobody seems to be using %ph with kasprintf, but we might as well fix it before it hits someone. Signed-off-by:
