From 29f178bddfdbd11218fbcba0b8060297696968e3 Mon Sep 17 00:00:00 2001 From: "Dr. David von Oheimb" Date: Wed, 30 Oct 2019 23:39:35 +0100 Subject: [PATCH] Generalize the HTTP client so far implemented mostly in crypto/ocsp/ocsp_ht.c The new client has become an independent libcrpyto module in crypto/http/ and * can handle any types of requests and responses (ASN.1-encoded and plain) * does not include potentially busy loops when waiting for responses but * makes use of a new timeout mechanism integrated with socket-based BIO * supports the use of HTTP proxies and TLS, including HTTPS over proxies * supports HTTP redirection via codes 301 and 302 for GET requests * returns more useful diagnostics in various error situations Also adapts - and strongly simplifies - hitherto uses of HTTP in crypto/ocsp/, crypto/x509/x_all.c, apps/lib/apps.c, and apps/{ocsp,s_client,s_server}.c Reviewed-by: Matt Caswell Reviewed-by: David von Oheimb (Merged from https://github.com/openssl/openssl/pull/10667) --- apps/include/apps.h | 26 + apps/lib/apps.c | 187 +++-- apps/ocsp.c | 123 +-- apps/s_client.c | 130 +--- apps/s_server.c | 13 +- crypto/build.info | 2 +- crypto/cmp/cmp_ctx.c | 2 +- crypto/cmp/cmp_err.c | 2 + crypto/cmp/cmp_local.h | 2 +- crypto/err/err.c | 1 + crypto/err/err_all.c | 2 + crypto/err/openssl.ec | 1 + crypto/err/openssl.txt | 28 +- crypto/http/build.info | 2 + crypto/http/http_client.c | 1238 +++++++++++++++++++++++++++++++ crypto/http/http_err.c | 67 ++ crypto/http/http_lib.c | 116 +++ crypto/http/http_local.h | 51 ++ crypto/ocsp/build.info | 2 +- crypto/ocsp/ocsp_err.c | 5 - crypto/ocsp/ocsp_ht.c | 502 ------------- crypto/ocsp/ocsp_http.c | 65 ++ crypto/ocsp/ocsp_lib.c | 107 --- crypto/x509/x_all.c | 29 +- doc/man3/OCSP_sendreq_new.pod | 49 +- doc/man3/OSSL_CMP_CTX_new.pod | 47 +- doc/man3/OSSL_HTTP_transfer.pod | 210 ++++++ doc/man3/X509_load_http.pod | 63 ++ include/openssl/cmp.h | 10 +- include/openssl/cmperr.h | 1 + include/openssl/err.h | 2 + include/openssl/http.h | 72 ++ include/openssl/httperr.h | 55 ++ include/openssl/ocsp.h | 35 +- include/openssl/ocsperr.h | 5 - include/openssl/types.h | 2 +- include/openssl/x509.h | 13 +- test/build.info | 8 + test/cmp_ctx_test.c | 9 +- test/http_test.c | 181 +++++ test/recipes/80-test_http.t | 21 + util/err-to-raise | 1 + util/libcrypto.num | 16 +- util/missingcrypto.txt | 3 +- util/other.syms | 5 +- 45 files changed, 2495 insertions(+), 1016 deletions(-) create mode 100644 crypto/http/build.info create mode 100644 crypto/http/http_client.c create mode 100644 crypto/http/http_err.c create mode 100644 crypto/http/http_lib.c create mode 100644 crypto/http/http_local.h delete mode 100644 crypto/ocsp/ocsp_ht.c create mode 100644 crypto/ocsp/ocsp_http.c create mode 100644 doc/man3/OSSL_HTTP_transfer.pod create mode 100644 doc/man3/X509_load_http.pod create mode 100644 include/openssl/http.h create mode 100644 include/openssl/httperr.h create mode 100644 test/http_test.c create mode 100644 test/recipes/80-test_http.t diff --git a/apps/include/apps.h b/apps/include/apps.h index c33a98772b..78be647619 100644 --- a/apps/include/apps.h +++ b/apps/include/apps.h @@ -28,12 +28,14 @@ # include # include # include +# include # include # include "apps_ui.h" # include "opt.h" # include "fmt.h" # include "platform.h" +/* also in include/internal/sockets.h */ # if defined(OPENSSL_SYS_WIN32) || defined(OPENSSL_SYS_WINCE) # define openssl_fdset(a,b) FD_SET((unsigned int)a, b) # else @@ -215,6 +217,30 @@ void print_cert_checks(BIO *bio, X509 *x, void store_setup_crl_download(X509_STORE *st);
