From mboxrd@z Thu Jan 1 00:00:00 1970 From: AKASHI Takahiro Date: Wed, 13 Nov 2019 09:44:46 +0900 Subject: [U-Boot] [PATCH v3 00/16] import x509/pkcs7 parsers from linux Message-ID: <20191113004502.29986-1-takahiro.akashi@linaro.org> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de # This patch set is a prerequisite for UEFI secure boot. # This patch set should be merged first prior to my rsa extension patch # due to some dependency. Asn1 parsers of x509 certificates and pkcs7 messages are required to implement image authentication and variable authentication as part of UEFI secure boot feature. As we discussed before in the thread[1], most people insisted that we should re-use corresponding source code from Linux repository for this purpose. Here is my attempt to import all the necessary files from Linux; Those will eventually be part of UEFI secure boot implementation, but I'd like to get early feedback from other peoples before submitting the whole patchset so that they will be better formatted for merging. My approach here is * files from the latest Linux * modify files as little as possible * mark/protect unavoidable changes with "#if(n)def __UBOOT__" so that future fixes/differences in Linux repository will easily be applied to U-Boot. Known issues: * checkpatch.pl Checkpatch.pl will complain with a bunch of warnings/errors but I intentionally left them unchanged for the sake of better maintainability I said above. -Takahiro Akashi [1] https://lists.denx.de/pipermail/u-boot/2019-April/366423.html Changes in v3 (Nov 13, 2019) * rebased to v2020.01-rc * improve function description of kmemdup() (patch#1) * remove test/lib/Kconfig (patch#16) * declare variables in unit test as static (patch#16) Changes in v2 (Oct 25, 2019) * revise commit messages, describing what files are modified or not. * move kmemdump() in ubifs.c to linux_compat.c for general use (patch#1) * add patch#2 * move date.c to lib/ for general use (patch#3) * implement mktime64() with rtc_mktime() (patch#4) * move asn1_compiler.c to tools/ (patch#7) * change CONFIG_BUILD_ASN1 to CONFIG_ASN1_COMPILER (patch#7) * add clean rule to asn1_compiler-generated files to clean targets (patch#8) * change CONFIG_ASN1 to CONFIG_ASN1_DECODER (patch#9) * add README for asn1 compiler/decoder (patch#10) * move build_oid_registry to scripts/ (patch#11) * shuffle an order of patches (patch#13,#14,#15) * add a new config CONFIG_RSA_PUBLIC_KEY_PARSER so that it can be * modify Kconfig dependency (patch#13,#14,#15) compiled in independently (patch#13) * add unit test (patch#16,#17) Changes in v1 (Oct 11, 2019) from RFC * change the kernel code base from v5.0 to v5.3 * add preparatory patches (#1, #2 and #3) * comment off x509_check_for_self_signed() which is not useful for UEFI secure boot (patch#9) * improve usages of "#if(n)def __UBOOT__* to minimize differences between U-Boot and linux kernel AKASHI Takahiro (16): linux_compat: move kmemdup() from ubifs.c to linux_compat.c rtc.h: add struct udevice declaration rtc: move date.c from drivers/rtc/ to lib/ lib: add mktime64() for linux compatibility include: kernel.h: include printk.h linux/time.h: include vsprintf.h cmd: add asn1_compiler Makefile: add build script for asn1 parsers lib: add asn1 decoder doc: add README for asn1 compiler and decoder lib: add oid registry utility lib: crypto: add public key utility lib: crypto: add rsa public key parser lib: crypto: add x509 parser lib: crypto: add pkcs7 message parser test: add asn1 unit test Makefile | 1 + cmd/Kconfig | 1 + doc/README.asn1 | 40 + drivers/rtc/Kconfig | 1 + drivers/rtc/Makefile | 1 - fs/ubifs/ubifs.c | 19 +- include/crypto/internal/rsa.h | 57 + include/crypto/pkcs7.h | 47 + include/crypto/public_key.h | 90 ++ include/keys/asymmetric-type.h | 88 ++ include/linux/asn1.h | 65 ++ include/linux/asn1_ber_bytecode.h | 89 ++ include/linux/asn1_decoder.h | 20 + include/linux/kernel.h | 2 +- include/linux/oid_registry.h | 117 +++ include/linux/time.h | 11 + include/rtc.h | 2 + lib/Kconfig | 17 + lib/Makefile | 20 + lib/asn1_decoder.c | 527 ++++++++++ lib/crypto/Kconfig | 52 + lib/crypto/Makefile | 49 + lib/crypto/asymmetric_type.c | 668 ++++++++++++ lib/crypto/pkcs7.asn1 | 135 +++ lib/crypto/pkcs7_parser.c | 693 +++++++++++++ lib/crypto/pkcs7_parser.h | 65 ++ lib/crypto/public_key.c | 376 +++++++ lib/crypto/rsa_helper.c | 198 ++++ lib/crypto/rsapubkey.asn1 | 4 + lib/crypto/x509.asn1 | 60 ++ lib/crypto/x509_akid.asn1 | 35 + lib/crypto/x509_cert_parser.c | 697 +++++++++++++ lib/crypto/x509_parser.h | 57 + lib/crypto/x509_public_key.c | 292 ++++++ {drivers/rtc => lib}/date.c | 23 +- lib/linux_compat.c | 19 + lib/oid_registry.c | 179 ++++ scripts/Makefile.build | 4 +- scripts/build_OID_registry | 203 ++++ test/Kconfig | 18 +- test/lib/Makefile | 1 + test/lib/asn1.c | 392 +++++++ tools/Makefile | 3 + tools/asn1_compiler.c | 1611 +++++++++++++++++++++++++++++ 44 files changed, 7024 insertions(+), 25 deletions(-) create mode 100644 doc/README.asn1 create mode 100644 include/crypto/internal/rsa.h create mode 100644 include/crypto/pkcs7.h create mode 100644 include/crypto/public_key.h create mode 100644 include/keys/asymmetric-type.h create mode 100644 include/linux/asn1.h create mode 100644 include/linux/asn1_ber_bytecode.h create mode 100644 include/linux/asn1_decoder.h create mode 100644 include/linux/oid_registry.h create mode 100644 lib/asn1_decoder.c create mode 100644 lib/crypto/Kconfig create mode 100644 lib/crypto/Makefile create mode 100644 lib/crypto/asymmetric_type.c create mode 100644 lib/crypto/pkcs7.asn1 create mode 100644 lib/crypto/pkcs7_parser.c create mode 100644 lib/crypto/pkcs7_parser.h create mode 100644 lib/crypto/public_key.c create mode 100644 lib/crypto/rsa_helper.c create mode 100644 lib/crypto/rsapubkey.asn1 create mode 100644 lib/crypto/x509.asn1 create mode 100644 lib/crypto/x509_akid.asn1 create mode 100644 lib/crypto/x509_cert_parser.c create mode 100644 lib/crypto/x509_parser.h create mode 100644 lib/crypto/x509_public_key.c rename {drivers/rtc => lib}/date.c (81%) create mode 100644 lib/oid_registry.c create mode 100755 scripts/build_OID_registry create mode 100644 test/lib/asn1.c create mode 100644 tools/asn1_compiler.c -- 2.21.0
