2020-09-17Revert "kbuild: use -flive-patching when CONFIG_LIVEPATCH is enabled"Josh Poimboeuf
[ Upstream commit 318af7b80b6a6751520cf2b71edb8c45abb9d9d8 ] Use of the new -flive-patching flag was introduced with the following commit: 43bd3a95c98e ("kbuild: use -flive-patching when CONFIG_LIVEPATCH is enabled") This flag has several drawbacks: - It disables some optimizations, so it can have a negative effect on performance. - According to the GCC documentation it's not compatible with LTO, which will become a compatibility issue as LTO support gets upstreamed in the kernel. - It was intended to be used for source-based patch generation tooling, as opposed to binary-based patch generation tooling (e.g., kpatch-build). It probably should have at least been behind a separate config option so as not to negatively affect other livepatch users. - Clang doesn't have the flag, so as far as I can tell, this method of generating patches is incompatible with Clang, which like LTO is becoming more mainstream. - It breaks GCC's implicit noreturn detection for local functions. This is the cause of several "unreachable instruction" objtool warnings. - The broken noreturn detection is an obvious GCC regression, but we haven't yet gotten GCC developers to acknowledge that, which doesn't inspire confidence in their willingness to keep the feature working as optimizations are added or changed going forward. - While there *is* a distro which relies on this flag for their distro livepatch module builds, there's not a publicly documented way to create safe livepatch modules with it. Its use seems to be based on tribal knowledge. It serves no benefit to those who don't know how to use it. (In fact, I believe the current livepatch documentation and samples are misleading and dangerous, and should be corrected. Or at least amended with a disclaimer. But I don't feel qualified to make such changes.) Also, we have an idea for using objtool to detect function changes, which could potentially obsolete the need for this flag anyway. At this point the flag has no benefits for upstream which would counteract the above drawbacks. Revert it until it becomes more ready. This reverts commit 43bd3a95c98e1a86b8b55d97f745c224ecff02b9.

2020-07-23Makefile: Fix GCC_TOOLCHAIN_DIR prefix for Clang cross compilationFangrui Song
When CROSS_COMPILE is set (e.g. aarch64-linux-gnu-), if $(CROSS_COMPILE)elfedit is found at /usr/bin/aarch64-linux-gnu-elfedit, GCC_TOOLCHAIN_DIR will be set to /usr/bin/. --prefix= will be set to /usr/bin/ and Clang as of 11 will search for both $(prefix)aarch64-linux-gnu-$needle and $(prefix)$needle. GCC searchs for $(prefix)aarch64-linux-gnu/$version/$needle, $(prefix)aarch64-linux-gnu/$needle and $(prefix)$needle. In practice, $(prefix)aarch64-linux-gnu/$needle rarely contains executables. To better model how GCC's -B/--prefix takes in effect in practice, newer Clang (since https://github.com/llvm/llvm-project/commit/3452a0d8c17f7166f479706b293caf6ac76ffd90) only searches for $(prefix)$needle. Currently it will find /usr/bin/as instead of /usr/bin/aarch64-linux-gnu-as. Set --prefix= to $(GCC_TOOLCHAIN_DIR)$(notdir $(CROSS_COMPILE)) (/usr/bin/aarch64-linux-gnu-) so that newer Clang can find the appropriate cross compiling GNU as (when -no-integrated-as is in effect).

2020-06-15Makefile: Improve compressed debug info support detectionArvind Sankar
Commit 10e68b02c861 ("Makefile: support compressed debug info") added support for compressed debug sections. Support is detected by checking - does the compiler support -gz=zlib - does the assembler support --compressed-debug-sections=zlib - does the linker support --compressed-debug-sections=zlib However, the gcc driver's support for this option is somewhat convoluted. The driver's builtin specs are set based on the version of binutils that it was configured with. It reports an error if the configure-time linker/assembler (i.e., not necessarily the actual assembler that will be run) do not support the option, but only if the assembler (or linker) is actually invoked when -gz=zlib is passed. The cc-option check in scripts/Kconfig.include does not invoke the assembler, so the gcc driver reports success even if it does not support the option being passed to the assembler. Because the as-option check passes the option directly to the assembler via -Wa,--compressed-debug-sections=zlib, the gcc driver does not see this option and will never report an error. Combined with an installed version of binutils that is more recent than the one the compiler was built with, it is possible for all three tests to succeed, yet an actual compilation with -gz=zlib to fail. Moreover, it is unnecessary to explicitly pass --compressed-debug-sections=zlib to the assembler via -Wa, since the driver will do that automatically when it supports -gz=zlib. Convert the as-option to just -gz=zlib, simplifying it as well as performing a better test of the gcc driver's capabilities.

Redefine GZIP, BZIP2, LZOP variables as KGZIP, KBZIP2, KLZOP resp. GZIP, BZIP2, LZOP env variables are reserved by the tools. The original attempt to redefine them internally doesn't work in makefiles/scripts intercall scenarios, e.g., "make GZIP=gzip bindeb-pkg" and results in broken builds. There can be other broken build commands because of this, so the universal solution is to use non-reserved env variables for the compression tools.
