46b41d5d - kbuild: update config_data.gz only when the content of .config is changed

Sun, 25 Apr 2021 06:24:07 +0000

kbuild: update config_data.gz only when the content of .config is changedIf the timestamp of the .config file is updated, config_data.gz isregenerated, then vmlinux is re-linked. This occurs even if the contentof the .config has not changed at all.This issue was mitigated by commit 67424f61f813 ("kconfig: do not write.config if the content is the same"); Kconfig does not update the.config when it ends up with the identical configuration.The issue is remaining when the .config is created by *_defconfig withsome config fragment(s) applied on top.This is typical for powerpc and mips, where several *_defconfig targetsare constructed by using merge_config.sh.One workaround is to have the copy of the .config. The filechk ruleupdates the copy, kernel/config_data, by checking the content insteadof the timestamp.With this commit, the second run with the same configuration avoidsthe needless rebuilds. $ make ARCH=mips defconfig all [ snip ] $ make ARCH=mips defconfig all *** Default configuration is based on target '32r2el_defconfig' Using ./arch/mips/configs/generic_defconfig as base Merging arch/mips/configs/generic/32r2.config Merging arch/mips/configs/generic/el.config Merging ./arch/mips/configs/generic/board-boston.config Merging ./arch/mips/configs/generic/board-ni169445.config Merging ./arch/mips/configs/generic/board-ocelot.config Merging ./arch/mips/configs/generic/board-ranchu.config Merging ./arch/mips/configs/generic/board-sead-3.config Merging ./arch/mips/configs/generic/board-xilfpga.config # # configuration written to .config # SYNC include/config/auto.conf CALL scripts/checksyscalls.sh CALL scripts/atomic/check-atomics.sh CHK include/generated/compile.h CHK include/generated/autoksyms.hReported-by: Elliot Berman Signed-off-by: Masahiro Yamada List of files: /linux-6.15/kernel/.gitignore

43d8ce9d - Provide in-kernel headers to make extending kernel easier

Fri, 26 Apr 2019 19:04:29 +0000

Provide in-kernel headers to make extending kernel easierIntroduce in-kernel headers which are made available as an archivethrough proc (/proc/kheaders.tar.xz file). This archive makes itpossible to run eBPF and other tracing programs that need to extend thekernel for tracing purposes without any dependency on the file systemhaving headers.A github PR is sent for the corresponding BCC patch at:https://github.com/iovisor/bcc/pull/2312On Android and embedded systems, it is common to switch kernels but nothave kernel headers available on the file system. Further once adifferent kernel is booted, any headers stored on the file system willno longer be useful. This is an issue even well known to distros.By storing the headers as a compressed archive within the kernel, we canavoid these issues that have been a hindrance for a long time.The best way to use this feature is by building it in. Several usershave a need for this, when they switch debug kernels, they do not want toupdate the filesystem or worry about it where to store the headers onit. However, the feature is also buildable as a module in case the userdesires it not being part of the kernel image. This makes it possible toload and unload the headers from memory on demand. A tracing program canload the module, do its operations, and then unload the module to savekernel memory. The total memory needed is 3.3MB.By having the archive available at a fixed location independent offilesystem dependencies and conventions, all debugging tools candirectly refer to the fixed location for the archive, without concerningwith where the headers on a typical filesystem which significantlysimplifies tooling that needs kernel headers.The code to read the headers is based on /proc/config.gz code and usesthe same technique to embed the headers.Other approaches were discussed such as having an in-memory mountablefilesystem, but that has drawbacks such as requiring an in-kernel xzdecompressor which we don't have today, and requiring usage of 42 MB ofkernel memory to host the decompressed headers at anytime. Also thisapproach is simpler than such approaches.Reviewed-by: Masahiro Yamada Signed-off-by: Joel Fernandes (Google) Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/kernel/.gitignore

13610aa9 - kernel/configs: use .incbin directive to embed config_data.gz

Fri, 08 Mar 2019 00:29:53 +0000

kernel/configs: use .incbin directive to embed config_data.gzThis slightly optimizes the kernel/configs.c build.bin2c is not very efficient because it converts a data file into a hugearray to embed it into a *.c file.Instead, we can use the .incbin directive.Also, this simplifies the code; Makefile is cleaner, and the way to getthe offset/size of the config_data.gz is more straightforward.I used the "asm" statement in *.c instead of splitting it into *.Sbecause MODULE_* tags are not supported in *.S files.I also cleaned up kernel/.gitignore; "config_data.gz" is unneededbecause the top-level .gitignore takes care of the "*.gz" pattern.[yamada.masahiro@socionext.com: v2] Link: http://lkml.kernel.org/r/1550108893-21226-1-git-send-email-yamada.masahiro@socionext.comLink: http://lkml.kernel.org/r/1549941160-8084-1-git-send-email-yamada.masahiro@socionext.comSigned-off-by: Masahiro Yamada Cc: Randy Dunlap Cc: Arnd Bergmann Cc: Alexander Popov Cc: Kees Cook Cc: Jonathan Corbet Cc: Thomas Gleixner Cc: Dan Williams Cc: Mathieu Desnoyers Cc: Richard Guy Briggs Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds List of files: /linux-6.15/kernel/.gitignore

48dbc164 - certs: add .gitignore to stop git nagging about x509_certificate_list
