Revision a520723f29aac6598ff0d69e34f5e9b88213e511 authored by Matt Caswell on 14 October 2016, 12:07:00 UTC, committed by Matt Caswell on 28 October 2016, 08:43:41 UTC
The previous commit inspired a review of all the length checks for the extension adding code. This adds more robust checks and adds checks where some were missing previously. The real solution for this is to use WPACKET which is currently in master - but that cannot be applied to release branches. Reviewed-by: Rich Salz <rsalz@openssl.org>

X509_STORE_CTX_get_ex_new_index.pod
=pod
=head1 NAME
X509_STORE_CTX_get_ex_new_index, X509_STORE_CTX_set_ex_data, X509_STORE_CTX_get_ex_data - add application specific data to X509_STORE_CTX structures
=head1 SYNOPSIS
#include <openssl/x509_vfy.h>
int X509_STORE_CTX_get_ex_new_index(long argl, void *argp,
CRYPTO_EX_new *new_func,
CRYPTO_EX_dup *dup_func,
CRYPTO_EX_free *free_func);
int X509_STORE_CTX_set_ex_data(X509_STORE_CTX *d, int idx, void *arg);
void *X509_STORE_CTX_get_ex_data(X509_STORE_CTX *d, int idx);
=head1 DESCRIPTION
These functions handle application specific data in X509_STORE_CTX structures.
Their usage is identical to that of RSA_get_ex_new_index(), RSA_set_ex_data()
and RSA_get_ex_data() as described in L<RSA_get_ex_new_index(3)>.
=head1 NOTES
This mechanism is used internally by the B<ssl> library to store the B<SSL>
structure associated with a verification operation in an B<X509_STORE_CTX>
structure.
=head1 SEE ALSO
L<RSA_get_ex_new_index(3)|RSA_get_ex_new_index(3)>
=head1 HISTORY
X509_STORE_CTX_get_ex_new_index(), X509_STORE_CTX_set_ex_data() and
X509_STORE_CTX_get_ex_data() are available since OpenSSL 0.9.5.
