* Free up ASN.1 structures at top level only.Dr. Stephen Henson2015-10-051-28/+40
| | | | | | | | When a decoding error in ASN.1 occurs only free up the partial structure at the top level. This simplifies embedded handling and fixes freeing up of structures when presented with malformed input. Reviewed-by: Rich Salz <rsalz@openssl.org>
* New ASN.1 embed macro.Dr. Stephen Henson2015-09-161-0/+10
| | | | | | | | | | | | | | | | | | | New ASN.1 macro ASN1_EMBED. This is the same as ASN1_SIMPLE except the structure is not allocated: it is part of the parent. That is instead of FOO *x; it must be: FOO x; This reduces memory fragmentation and make it impossible to accidentally set a mandatory field to NULL. This currently only works for SEQUENCE and since it is equivalent to ASN1_SIMPLE it cannot be tagged, OPTIONAL, SET OF or SEQUENCE OF. Reviewed-by: Rich Salz <rsalz@openssl.org>

* Initialize potentially uninitialized local variablesGunnar Kudrjavets2015-05-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Compiling OpenSSL code with MSVC and /W4 results in a number of warnings. One category of warnings is particularly interesting - C4701 (potentially uninitialized local variable 'name' used). This warning pretty much means that there's a code path which results in uninitialized variables being used or returned. Depending on compiler, its options, OS, values in registers and/or stack, the results can be nondeterministic. Cases like this are very hard to debug so it's rational to fix these issues. This patch contains a set of trivial fixes for all the C4701 warnings (just initializing variables to 0 or NULL or appropriate error code) to make sure that deterministic values will be returned from all the execution paths. RT#3835 Signed-off-by: Matt Caswell <matt@openssl.org> Matt's note: All of these appear to be bogus warnings, i.e. there isn't actually a code path where an unitialised variable could be used - its just that the compiler hasn't been able to figure that out from the logic. So this commit is just about silencing spurious warnings. Reviewed-by: Rich Salz <rsalz@openssl.org>

| | | | | | | | | Remove old ASN.1 COMPAT type. This was meant as a temporary measure so older ASN.1 code (from OpenSSL 0.9.6) still worked. It's a hack which breaks constification and hopefully nothing uses it now, if it ever did. Reviewed-by: Matt Caswell <matt@openssl.org>

* More linker bloat reorganisation:Dr. Stephen Henson2001-07-271-0/+19
| | | | | | | | | | | | | | | | | | | | | Split private key PEM and normal PEM handling. Private key handling needs to link in stuff like PKCS#8. Relocate the ASN1 *_dup() functions, to the relevant ASN1 modules using new macro IMPLEMENT_ASN1_DUP_FUNCTION. Previously these were all in crypto/x509/x_all.c along with every ASN1 BIO/fp function which linked in *every* ASN1 function if a single dup was used. Move the authority key id ASN1 structure to a separate file. This is used in the X509 routines and its previous location linked in all the v3 extension code. Also move ASN1_tag2bit to avoid linking in a_bytes.c which is now largely obsolete. So far under Linux stripped binary with single PEM_read_X509 is now 238K compared to 380K before these changes.
