The issue with r1653906 is that existing configurations like
"SSLProtocol -SSLv3" (where the default is assumed to be ALL)
won't work anymore.

It controls the use of TLS session tickets
(RFC 5077). Default is unchanged (on).
Using session tickets without restarting
the web server with an appropriate frequency
(e.g. daily) compromises perfect forward
secrecy.
As long as we do not have a nice key management
there should be a way to deactivate session
tickets.

(ex_data attached to an X509 *) to a per-server hash which is
allocated from the pconf pool. Fixes PR 54357, PR 56919 and
a leak with the certinfo_free cleanup function (missing
OCSP_CERTID_free).
* modules/ssl/ssl_util_stapling.c: drop certinfo_free, and add
ssl_stapling_certid_free (used with apr_pool_cleanup_register).
Switch to a stapling_certinfo hash which is keyed by the SHA-1
digest of the certificate's DER encoding, rework ssl_stapling_init_cert
to only store info once per certificate (allocated from the pconf
to the extent possible) and extend the logging.
* modules/ssl/ssl_private.h: adjust prototype for
ssl_stapling_init_cert, replace ssl_stapling_ex_init with
ssl_stapling_certinfo_hash_init
* modules/ssl/ssl_engine_init.c: adjust ssl_stapling_* calls

- no longer send a warning-level unrecognized_name(112) alert
when no matching vhost is found (PR 56241)
- at startup, only issue warnings about IP/port conflicts and name-based
SSL vhosts when running with an OpenSSL without TLS extension support
(almost 5 years after SNI was added to 2.2.x, the
"[...] only work for clients with TLS server name indication support"
warning feels obsolete)

in SSL_get_certificate for servers where the certificate hasn't
been sent.
Workaround by setting the ssl structure to client mode which
bypasses the faulty code in OpenSSL. Normally setting a server
ssl structure to client mode would cause problems later on:
but we are freeing the structure immediately without attempting
to use it.

and SSLCertificateKeyFile directives, and deprecate SSLCertificateChainFile
Splitting the patch into smaller pieces turned out to be infeasible,
unfortunately, due to the heavily intertwined code in ssl_engine_config.c,
ssl_engine_init.c and ssl_engine_pphrase.c, which all depends on the
modssl_pk_server_t data structure. For better comprehensibility,
a detailed listing of the changes follows:
ssl_private.h
- drop the X509 certs and EVP_PKEY keys arrays from modssl_pk_server_t
- use apr_array_header_t for cert_files and key_files
- drop tPublicCert from SSLModConfigRec
- drop the ssl_algo_t struct and the SSL_ALGO_* and SSL_AIDX_* constants
ssl_engine_config.c
- change to apr_array_header_t for SSLCertificate[Key]File
- drop ssl_cmd_check_aidx_max, i.e. allow an arbitrary number of certs
and keys (in theory; currently OpenSSL does not support more than
one cert/key per algorithm type)
- add deprecation warning for SSLCertificateChainFile
ssl_engine_init.c
- configure server certs/keys in ssl_init_server_certs (no longer via
ssl_pphrase_Handle in ssl_init_Module)
- in ssl_init_server_certs, read in certificates and keys with standard
OpenSSL API functions (SSL_CTX_use_*_file), and only fall back to
ssl_load_encrypted_pkey when encountering an encrypted private key
- drop ssl_server_import_cert, ssl_server_import_key, ssl_init_server_check,
and ssl_init_ctx_cleanup_server
- move the "problematic re-initialization" check to ssl_init_server_ctx
ssl_engine_pphrase.c
- use servername:port:index as the key identifier, instead of the
previously used servername:port:algorithm
- ssl_pphrase_Handle overhaul: remove all cert/public-key handling,
make it only load a single (encrypted) private key, and rename
to ssl_load_encrypted_pkey
- in the passphrase prompt message, show the private key file name
instead of the vhost id and the algorithm name
- do no longer supply the algorithm name as an argument to "exec"-type
passphrase prompting programs
ssl_util.c
- drop ssl_util_algotypeof, ssl_util_algotypestr, ssl_asn1_keystr,
and ssl_asn1_table_keyfmt
ssl_util_ssl.{c,h}
- drop SSL_read_X509
- constify the filename arg for SSL_read_PrivateKey

- use cfgMergeArray, and reduce the size of the initial array
- move SSL_CONF_cmd calls from ssl_init_ctx_protocol to
ssl_init_server_ctx (so they are applied after ssl_init_server_certs)
- add APLOG_DEBUG-level logging for the SSL_CONF_cmd success case
- call SSL_CONF_CTX_free(cctx) when done in ssl_init_server_ctx
git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1546693 13f79535-47bb-0310-9956-ffa450edef68
- was never documented, so very unlikely that it was ever used
- adds complexity without apparent benefit; PKCS#7 files can
be trivially converted to a file for use with SSLCertificateChainFile
(concatenated X509 CERTIFICATE chunks, openssl pkcs7 -print_certs...)
- only supports PKCS7 files with PEM encoding, i.e. relies on a
non-standardized PEM header (cf. RFC 2315 and draft-josefsson-pkix-textual)
- issues pointed out in http://mail-archives.apache.org/mod_mbox/httpd-dev/200607.mbox/%3C20060723093125.GA19423@redhat.com%3E
were never fully addressed (cf. r424707 and r424735)
- has never worked in vhost context due to a cfgMergeString
call missing from modssl_ctx_cfg_merge

* modules/ssl/ssl_engine_config.c (ssl_config_server_new): Default
sc->enabled to UNSET.
* modules/ssl/ssl_engine_init.c (ssl_init_Module): Only override
sc->enabled based on the protocol iff sc->enabled is UNSET; allows
"SSLEngine off" to override the Listen-based default.

- allow to configure custom DHE or ECDHE parameters via the
SSLCertificateFile directive, and adapt its documentation
accordingly (addresses PR 49559)
- add standardized DH parameters from RFCs 2409 and 3526,
use them based on the length of the certificate's RSA/DSA key,
and add a FAQ entry for clients which limit DH support
to 1024 bits (such as Java 7 and earlier)
- move ssl_dh_GetParamFromFile() from ssl_engine_dh.c to
ssl_util_ssl.c, and add ssl_ec_GetParamFromFile()
- drop ssl_engine_dh.c from mod_ssl
For the standardized DH parameters, OpenSSL version 0.9.8a
or later is required, which was therefore made a new minimum
requirement in r1527294.

- drop SSL_TMP_KEY_* constants from ssl_private.h, too
- make sure we also disable aNULL, eNULL and EXP ciphers
for per-directory SSLCipherSuite directives
- apply the same treatment to SSLProxyCipherSuite

- drop support for ephemeral RSA keys (only allowed/needed
for export ciphers)
- drop pTmpKeys from the per-process SSLModConfigRec, and remove
the temp key generation at startup (unnecessary for DHE/ECDHE)
- unconditionally disable null and export-grade ciphers by always
prepending "!aNULL:!eNULL:!EXP:" to any cipher suite string
- do not configure per-connection SSL_tmp_*_callbacks, as it is
sufficient to set them for the SSL_CTX
- set default curve for ECDHE at startup, obviating the need
for a per-handshake callback, for the time being (and also
configure SSL_OP_SINGLE_ECDH_USE, previously left out)
