Change SECURE_UPGRADE_DEV_SIGNING_CERT to SECURE_UPGRADE_SIGNING_CERT (#14591)
Depends on https://github.com/sonic-net/sonic-linux-kernel/pull/315 #### Why I did it The name SECURE_UPGRADE_DEV_SIGNING_CERT is misleading, this flag is relevant to both to dev and prod signing. #### How I did it Rename all mentions of name SECURE_UPGRADE_DEV_SIGNING_CERT to SECURE_UPGRADE_SIGNING_CERT - this is also done with PR in sonic-linux-kernel repository #### How to verify it Build SONiC using your own prod script |

Add Secure Boot Support (#12692)
- Why I did it Add Secure Boot support to SONiC OS. Secure Boot (SB) is a verification mechanism for ensuring that code launched by a computer's UEFI firmware is trusted. It is designed to protect a system against malicious code being loaded and executed early in the boot process before the operating system has been loaded. - How I did it Added a signing process to sign the following components: shim, grub, Linux kernel, and kernel modules when doing the build, and when feature is enabled in build time according to the HLD explanations (the feature is disabled by default). - How to verify it There are self-verifications of each boot component when building the image, in addition, there is an existing end-to-end test in sonic-mgmt repo that checks that the boot succeeds when loading a secure system (details below). How to build a sonic image with secure boot feature: (more description in HLD) Required to use the following build flags from rules/config: SECURE_UPGRADE_MODE="dev" SECURE_UPGRADE_DEV_SIGNING_KEY="/path/to/private/key.pem" SECURE_UPGRADE_DEV_SIGNING_CERT="/path/to/cert/key.pem" After setting those flags should build the sonic-buildimage. Before installing the image, should prepared the setup (switch device) with the follow: check that the device support UEFI stored pub keys in UEFI DB enabled Secure Boot flag in UEFI How to run a test that verify the Secure Boot flow: The existing test "test_upgrade_path" under "sonic-mgmt/tests/upgrade_path/test_upgrade_path", is enough to validate proper boot You need to specify the following arguments: Base_image_list your_secure_image Taget_image_list your_second_secure_image Upgrade_type cold And run the test, basically the test will install the base image given in the parameter and then upgrade to target image by doing cold reboot and validates all the services are up and working correctly |

[Build]: Improve the linux kernel build cache hit rate (#9604)
Improve the Linux kernel build cache hit rate. Current the the hit rate is around 85.8% (based on the last 3 month, 3479 PR builds totally, 494 PR build not hit). We can improve the hit rate up to 95% or better. The Linux kernel build will take really long time, most of the PRs are nothing to do with the kernel change. The remaining cache options should be enough to detect the Linux kernel cache status (dirty or not). |

[build]: support for DPKG local caching (#4117)
DPKG caching framework provides the infrastructure to cache the sonic module/target .deb files into a local cache by tracking the target dependency files.SONIC build infrastructure is designed as a plugin framework where any new source code can be easily integrated into sonic as a module and that generates output as a .deb file. The source code compilation of a module is completely independent of other modules compilation. Inter module dependency is resolved through build artifacts like header files, libraries, and binaries in the form of Debian packages. For example module A depends on module B. While module A is being built, it uses B's .deb file to install it in the build docker.
The DPKG caching framework provides an infrastructure that caches a module's deb package and restores it back to the build directory if its dependency files are not modified. When a module is compiled for the first time, the generated deb package is stored at the DPKG cache location. On the subsequent build, first, it checks the module dependency file modification. If none of the dependent files is changed, it copies the deb package from the cache location, otherwise, it goes for local compilation and generates the deb package. The modified files should be checked-in to get the newer cache deb package.
This provides a huge improvement in build time and also supports the true incremental build by tracking the dependency files.
- How I did it
It takes two global arguments to enable the DPKG caching, the first one indicates the caching method and the second one describes the location of the cache.
SONIC_DPKG_CACHE_METHOD=cache
SONIC_DPKG_CACHE_SOURCE=
where SONIC_DPKG_CACHE_METHOD - Default method is 'cache' for deb package caching
none: no caching
cache: cache from local directory
Dependency file tracking:
Dependency files are tracked for each target in two levels.
1. Common make infrastructure files - rules/config, rules/functions, slave.mk etc.
2. Per module files - files which are specific to modules, Makefile, debian/rules, patch files, etc.
For example: dependency files for Linux Kernel - src/sonic-linux-kernel,
SPATH := $($(LINUX_HEADERS_COMMON)_SRC_PATH)
DEP_FILES := $(SONIC_COMMON_FILES_LIST) rules/linux-kernel.mk rules/linux-kernel.dep
DEP_FILES += $(SONIC_COMMON_BASE_FILES_LIST)
SMDEP_FILES := $(addprefix $(SPATH)/,$(shell cd $(SPATH) && git ls-files))
DEP_FLAGS := $(SONIC_COMMON_FLAGS_LIST) \
$(KERNEL_PROCURE_METHOD) $(KERNEL_CACHE_PATH)
$(LINUX_HEADERS_COMMON)_CACHE_MODE := GIT_CONTENT_SHA
$(LINUX_HEADERS_COMMON)_DEP_FLAGS := $(DEP_FLAGS)
$(LINUX_HEADERS_COMMON)_DEP_FILES := $(DEP_FILES)
$(LINUX_HEADERS_COMMON)_SMDEP_FILES := $(SMDEP_FILES)
$(LINUX_HEADERS_COMMON)_SMDEP_PATHS := $(SPATH)
Cache file tracking:
The Cache file is a compressed TAR ball of a module's target DEB file and its derived-target DEB files.
The cache filename is formed with the following format
FORMAT:
<module deb filename>.<24 byte of DEP SHA hash >-<24 byte of MOD SHA hash>.tgz
Eg:
linux-headers-4.9.0-9-2-common_4.9.168-1+deb9u3_all.deb-23658712fd21bb776fa16f47-c0b63ef593d4a32643bca228.tgz
< 24-byte DEP SHA value > - the SHA value is derived from all the dependent packages.
< 24-byte MOD SHA value > - the SHA value is derived from either of the following.
GIT_COMMIT_SHA - SHA value of the last git commit ID if it is a submodule
GIT_CONTENT_SHA - SHA value is generated from the content of the target dependency files.
Target Specific rules:
Caching can be enabled/disabled on a global level and also on the per-target level.
$(addprefix $(DEBS_PATH)/, $(SONIC_DPKG_DEBS)) : $(DEBS_PATH)/% : .platform $$(addsuffix -install,$$(addprefix $(DEBS_PATH)/,$$($$*_DEPENDS))) \
$(call dpkg_depend,$(DEBS_PATH)/%.dep )
$(HEADER)
# Load the target deb from DPKG cache
$(call LOAD_CACHE,$*,$@)
# Skip building the target if it is already loaded from cache
if [ -z '$($*_CACHE_LOADED)' ] ; then
.....
# Rules for Generating the target DEB file.
.....
# Save the target deb into DPKG cache
$(call SAVE_CACHE,$*,$@)
fi
$(FOOTER)
The make rule-'$(call dpkg_depend,$(DEBS_PATH)/%.dep )' checks for target dependency file modification. If it is newer than the target, it will go for re-generation of that target.
Two main macros 'LOAD_CACHE' and 'SAVE_CACHE' are used for loading and storing the cache contents.
The 'LOAD_CACHE' macro is used to load the cache file from cache storage and extracts them into the target folder. It is done only if target dependency files are not modified by checking the GIT file status, otherwise, cache loading is skipped and full compilation is performed.
It also updates the target-specific variable to indicate the cache is loaded or not.
The 'SAVE_CACHE' macro generates the compressed tarball of the cache file and saves them into cache storage. Saving into the cache storage is protected with a lock.
- How to verify it
The caching functionality is verified by enabling it in Linux kernel submodule.
It uses the cache directory as 'target/cache' where Linux cache file gets stored on the first-time build and it is picked from the cache location during the subsequent clean build.
- Description for the changelog
The DPKG caching framework provides the infrastructure to save the module-specific deb file to be cached by tracking the module's dependency files.
If the module's dependency files are not changed, it restores the module deb files from the cache storage.
