-Subject: arch: fix broken BuildID for arm64 and riscv
-
-From: Masahiro Yamada <masahiroy@kernel.org>
-
-commit 99cb0d917ffa1ab628bb67364ca9b162c07699b1 upstream.
-
-Dennis Gilmore reports that the BuildID is missing in the arm64 vmlinux
-since commit 994b7ac1697b ("arm64: remove special treatment for the
-link order of head.o").
-
-The issue is that the type of .notes section, which contains the BuildID,
-changed from NOTES to PROGBITS.
-
-Ard Biesheuvel figured out that whichever object gets linked first gets
-to decide the type of a section. The PROGBITS type is the result of the
-compiler emitting .note.GNU-stack as PROGBITS rather than NOTE.
-
-While Ard provided a fix for arm64, I want to fix this globally because
-the same issue is happening on riscv since commit 2348e6bf4421 ("riscv:
-remove special treatment for the link order of head.o"). This problem
-will happen in general for other architectures if they start to drop
-unneeded entries from scripts/head-object-list.txt.
-
-Discard .note.GNU-stack in include/asm-generic/vmlinux.lds.h.

-Subject: powerpc/vmlinux.lds: Define RUNTIME_DISCARD_EXIT
-
-From: Michael Ellerman <mpe@ellerman.id.au>
-
-commit 4b9880dbf3bdba3a7c56445137c3d0e30aaa0a40 upstream.
-
-The powerpc linker script explicitly includes .exit.text, because
-otherwise the link fails due to references from __bug_table and
-__ex_table. The code is freed (discarded) at runtime along with
-.init.text and data.
-
-That has worked in the past despite powerpc not defining
-RUNTIME_DISCARD_EXIT because DISCARDS appears late in the powerpc linker
-script (line 410), and the explicit inclusion of .exit.text
-earlier (line 280) supersedes the discard.
-
-However commit 99cb0d917ffa ("arch: fix broken BuildID for arm64 and
-riscv") introduced an earlier use of DISCARD as part of the RO_DATA
-macro (line 136). With binutils < 2.36 that causes the DISCARD
-directives later in the script to be applied earlier [1], causing
-.exit.text to actually be discarded at link time, leading to build
-errors:
-
- '.exit.text' referenced in section '__bug_table' of crypto/algboss.o: defined in
- discarded section '.exit.text' of crypto/algboss.o
- '.exit.text' referenced in section '__ex_table' of drivers/nvdimm/core.o: defined in
- discarded section '.exit.text' of drivers/nvdimm/core.o
-
-Fix it by defining RUNTIME_DISCARD_EXIT, which causes the generic
-DISCARDS macro to not include .exit.text at all.

-Subject: s390: define RUNTIME_DISCARD_EXIT to fix link error with GNU ld < 2.36
-
-From: Masahiro Yamada <masahiroy@kernel.org>
-
-commit a494398bde273143c2352dd373cad8211f7d94b2 upstream.
-
-Nathan Chancellor reports that the s390 vmlinux fails to link with
-GNU ld < 2.36 since commit 99cb0d917ffa ("arch: fix broken BuildID
-for arm64 and riscv").
-
-It happens for defconfig, or more specifically for CONFIG_EXPOLINE=y.
-
- $ s390x-linux-gnu-ld --version | head -n1
- GNU ld (GNU Binutils for Debian) 2.35.2
- $ make -s ARCH=s390 CROSS_COMPILE=s390x-linux-gnu- allnoconfig
- $ ./scripts/config -e CONFIG_EXPOLINE
- $ make -s ARCH=s390 CROSS_COMPILE=s390x-linux-gnu- olddefconfig
- $ make -s ARCH=s390 CROSS_COMPILE=s390x-linux-gnu-
- `.exit.text' referenced in section `.s390_return_reg' of drivers/base/dd.o: defined in discarded section `.exit.text' of drivers/base/dd.o
- make[1]: *** [scripts/Makefile.vmlinux:34: vmlinux] Error 1
- make: *** [Makefile:1252: vmlinux] Error 2
-
-arch/s390/kernel/vmlinux.lds.S wants to keep EXIT_TEXT:
-
- .exit.text : {
- EXIT_TEXT
- }
-
-But, at the same time, EXIT_TEXT is thrown away by DISCARD because
-s390 does not define RUNTIME_DISCARD_EXIT.
-
-I still do not understand why the latter wins after 99cb0d917ffa,
-but defining RUNTIME_DISCARD_EXIT seems correct because the comment
-line in arch/s390/kernel/vmlinux.lds.S says:
-
- /*
- * .exit.text is discarded at runtime, not link time,
- * to deal with references from __bug_table
- */
-
-Nathan also found that binutils commit 21401fc7bf67 ("Duplicate output
-sections in scripts") cured this issue, so we cannot reproduce it with
-binutils 2.36+, but it is better to not rely on it.

-Subject: s390: define RUNTIME_DISCARD_EXIT to fix link error with GNU ld < 2.36
-
-From: Masahiro Yamada <masahiroy@kernel.org>
-
-commit a494398bde273143c2352dd373cad8211f7d94b2 upstream.
-
-Nathan Chancellor reports that the s390 vmlinux fails to link with
-GNU ld < 2.36 since commit 99cb0d917ffa ("arch: fix broken BuildID
-for arm64 and riscv").
-
-It happens for defconfig, or more specifically for CONFIG_EXPOLINE=y.
-
- $ s390x-linux-gnu-ld --version | head -n1
- GNU ld (GNU Binutils for Debian) 2.35.2
- $ make -s ARCH=s390 CROSS_COMPILE=s390x-linux-gnu- allnoconfig
- $ ./scripts/config -e CONFIG_EXPOLINE
- $ make -s ARCH=s390 CROSS_COMPILE=s390x-linux-gnu- olddefconfig
- $ make -s ARCH=s390 CROSS_COMPILE=s390x-linux-gnu-
- `.exit.text' referenced in section `.s390_return_reg' of drivers/base/dd.o: defined in discarded section `.exit.text' of drivers/base/dd.o
- make[1]: *** [scripts/Makefile.vmlinux:34: vmlinux] Error 1
- make: *** [Makefile:1252: vmlinux] Error 2
-
-arch/s390/kernel/vmlinux.lds.S wants to keep EXIT_TEXT:
-
- .exit.text : {
- EXIT_TEXT
- }
-
-But, at the same time, EXIT_TEXT is thrown away by DISCARD because
-s390 does not define RUNTIME_DISCARD_EXIT.
-
-I still do not understand why the latter wins after 99cb0d917ffa,
-but defining RUNTIME_DISCARD_EXIT seems correct because the comment
-line in arch/s390/kernel/vmlinux.lds.S says:
-
- /*
- * .exit.text is discarded at runtime, not link time,
- * to deal with references from __bug_table
- */
-
-Nathan also found that binutils commit 21401fc7bf67 ("Duplicate output
-sections in scripts") cured this issue, so we cannot reproduce it with
-binutils 2.36+, but it is better to not rely on it.

-
-From: Masahiro Yamada <masahiroy@kernel.org>
-
-commit 99cb0d917ffa1ab628bb67364ca9b162c07699b1 upstream.
-
-Dennis Gilmore reports that the BuildID is missing in the arm64 vmlinux
-since commit 994b7ac1697b ("arm64: remove special treatment for the
-link order of head.o").
-
-The issue is that the type of .notes section, which contains the BuildID,
-changed from NOTES to PROGBITS.
-
-Ard Biesheuvel figured out that whichever object gets linked first gets
-to decide the type of a section. The PROGBITS type is the result of the
-compiler emitting .note.GNU-stack as PROGBITS rather than NOTE.
-
-While Ard provided a fix for arm64, I want to fix this globally because
-the same issue is happening on riscv since commit 2348e6bf4421 ("riscv:
-remove special treatment for the link order of head.o"). This problem
-will happen in general for other architectures if they start to drop
-unneeded entries from scripts/head-object-list.txt.
-
-Discard .note.GNU-stack in include/asm-generic/vmlinux.lds.h.

-Subject: powerpc/vmlinux.lds: Define RUNTIME_DISCARD_EXIT
-
-From: Michael Ellerman <mpe@ellerman.id.au>
-
-commit 4b9880dbf3bdba3a7c56445137c3d0e30aaa0a40 upstream.
-
-The powerpc linker script explicitly includes .exit.text, because
-otherwise the link fails due to references from __bug_table and
-__ex_table. The code is freed (discarded) at runtime along with
-.init.text and data.
-
-That has worked in the past despite powerpc not defining
-RUNTIME_DISCARD_EXIT because DISCARDS appears late in the powerpc linker
-script (line 410), and the explicit inclusion of .exit.text
-earlier (line 280) supersedes the discard.
-
-However commit 99cb0d917ffa ("arch: fix broken BuildID for arm64 and
-riscv") introduced an earlier use of DISCARD as part of the RO_DATA
-macro (line 136). With binutils < 2.36 that causes the DISCARD
-directives later in the script to be applied earlier [1], causing
-.exit.text to actually be discarded at link time, leading to build
-errors:
-
- '.exit.text' referenced in section '__bug_table' of crypto/algboss.o: defined in
- discarded section '.exit.text' of crypto/algboss.o
- '.exit.text' referenced in section '__ex_table' of drivers/nvdimm/core.o: defined in
- discarded section '.exit.text' of drivers/nvdimm/core.o
-
-Fix it by defining RUNTIME_DISCARD_EXIT, which causes the generic
-DISCARDS macro to not include .exit.text at all.

-
-commit be5f95c8779e19779dd81927c8574fec5aaba36c upstream.
-
-Although the powerpc linker script mentions .comment in the DISCARD
-section, that has never actually caused it to be discarded, because the
-earlier ELF_DETAILS macro (previously STABS_DEBUG) explicitly includes
-.comment.
-
-However commit 99cb0d917ffa ("arch: fix broken BuildID for arm64 and

-the script to be applied earlier, causing .comment to actually be
-discarded.
-
-It's confusing to explicitly include and discard .comment, and even more
-so if the behaviour depends on the toolchain version. So don't discard
-.comment in order to maintain the existing behaviour in all cases.

-Subject: powerpc/vmlinux.lds: Don't discard .rela* for relocatable builds
-
-From: Michael Ellerman <mpe@ellerman.id.au>
-
-commit 07b050f9290ee012a407a0f64151db902a1520f5 upstream.
-
-Relocatable kernels must not discard relocations, they need to be
-processed at runtime. As such they are included for CONFIG_RELOCATABLE
-builds in the powerpc linker script (line 340).
-
-However they are also unconditionally discarded later in the
-script (line 414). Previously that worked because the earlier inclusion
-superseded the discard.
-
-However commit 99cb0d917ffa ("arch: fix broken BuildID for arm64 and
-riscv") introduced an earlier use of DISCARD as part of the RO_DATA
-macro (line 137). With binutils < 2.36 that causes the DISCARD
-directives later in the script to be applied earlier, causing .rela* to
-actually be discarded at link time, leading to build warnings and a
-kernel that doesn't boot:
-
- ld: warning: discarding dynamic section .rela.init.rodata
-
-Fix it by conditionally discarding .rela* only when CONFIG_RELOCATABLE
-is disabled.

-Subject: powerpc/vmlinux.lds: Don't discard .comment
-
-From: Michael Ellerman <mpe@ellerman.id.au>
-
-commit be5f95c8779e19779dd81927c8574fec5aaba36c upstream.
-
-Although the powerpc linker script mentions .comment in the DISCARD
-section, that has never actually caused it to be discarded, because the
-earlier ELF_DETAILS macro (previously STABS_DEBUG) explicitly includes
-.comment.
-
-However commit 99cb0d917ffa ("arch: fix broken BuildID for arm64 and
-riscv") introduced an earlier use of DISCARD as part of the RO_DATA
-macro. With binutils < 2.36 that causes the DISCARD directives later in
-the script to be applied earlier, causing .comment to actually be
-discarded.
-
-It's confusing to explicitly include and discard .comment, and even more
-so if the behaviour depends on the toolchain version. So don't discard
-.comment in order to maintain the existing behaviour in all cases.

-Subject: powerpc/vmlinux.lds: Don't discard .rela* for relocatable builds
-
-From: Michael Ellerman <mpe@ellerman.id.au>
-
-commit 07b050f9290ee012a407a0f64151db902a1520f5 upstream.
-
-Relocatable kernels must not discard relocations, they need to be
-processed at runtime. As such they are included for CONFIG_RELOCATABLE
-builds in the powerpc linker script (line 340).
-
-However they are also unconditionally discarded later in the
-script (line 414). Previously that worked because the earlier inclusion
-superseded the discard.
-
-However commit 99cb0d917ffa ("arch: fix broken BuildID for arm64 and
-riscv") introduced an earlier use of DISCARD as part of the RO_DATA
-macro (line 137). With binutils < 2.36 that causes the DISCARD
-directives later in the script to be applied earlier, causing .rela* to
-actually be discarded at link time, leading to build warnings and a
-kernel that doesn't boot:
-
- ld: warning: discarding dynamic section .rela.init.rodata
-
-Fix it by conditionally discarding .rela* only when CONFIG_RELOCATABLE
-is disabled.

-Subject: s390: define RUNTIME_DISCARD_EXIT to fix link error with GNU ld < 2.36
-
-From: Masahiro Yamada <masahiroy@kernel.org>
-
-commit a494398bde273143c2352dd373cad8211f7d94b2 upstream.
-
-Nathan Chancellor reports that the s390 vmlinux fails to link with
-GNU ld < 2.36 since commit 99cb0d917ffa ("arch: fix broken BuildID
-for arm64 and riscv").
-
-It happens for defconfig, or more specifically for CONFIG_EXPOLINE=y.
-
- $ s390x-linux-gnu-ld --version | head -n1
- GNU ld (GNU Binutils for Debian) 2.35.2
- $ make -s ARCH=s390 CROSS_COMPILE=s390x-linux-gnu- allnoconfig
- $ ./scripts/config -e CONFIG_EXPOLINE
- $ make -s ARCH=s390 CROSS_COMPILE=s390x-linux-gnu- olddefconfig
- $ make -s ARCH=s390 CROSS_COMPILE=s390x-linux-gnu-
- `.exit.text' referenced in section `.s390_return_reg' of drivers/base/dd.o: defined in discarded section `.exit.text' of drivers/base/dd.o
- make[1]: *** [scripts/Makefile.vmlinux:34: vmlinux] Error 1
- make: *** [Makefile:1252: vmlinux] Error 2
-
-arch/s390/kernel/vmlinux.lds.S wants to keep EXIT_TEXT:
-
- .exit.text : {
- EXIT_TEXT
- }
-
-But, at the same time, EXIT_TEXT is thrown away by DISCARD because
-s390 does not define RUNTIME_DISCARD_EXIT.
-
-I still do not understand why the latter wins after 99cb0d917ffa,
-but defining RUNTIME_DISCARD_EXIT seems correct because the comment
-line in arch/s390/kernel/vmlinux.lds.S says:
-
- /*
- * .exit.text is discarded at runtime, not link time,
- * to deal with references from __bug_table
- */
-
-Nathan also found that binutils commit 21401fc7bf67 ("Duplicate output
-sections in scripts") cured this issue, so we cannot reproduce it with
-binutils 2.36+, but it is better to not rely on it.
