Releng x86 builds later than 20240513 seem unable to run on older CPUs. 20240513 is the last working, 20240520 is the first broken. I'm working in qemu to reproduce & troubleshoot. The ISOs fail during initramfs startup. Actual error is "[!!] init (/sbin/init) not found in mounted root" but I think some commands are failing due to the libc breakage. Chroot fails with "/usr/lib/libc.so.6: CPU ISA level is lower than required" Checking by -cpu type: pentium FAIL pentium2 FAIL pentium3 FAIL coreduo-v1 SUCCESS athlon-v1 SUCCESS I'm not sure yet how to get qemu to use something pentium4-ish, so I don't know where the line of breakage is yet. Here is emerge --info from the athlon-v1 attempt, obviously I can't run it on one of the FAIL cases. -------------- Portage 3.0.63 (python 3.12.3-final-0, unavailable, gcc-13, glibc-2.39-r6, 6.6.30-gentoo-x86 i686) ================================================================= System Settings ================================================================= System uname: Linux-6.6.30-gentoo-x86-i686-QEMU_Virtual_CPU_version_2.5+-with-glibc2.39 KiB Mem: 2067344 total, 1688384 free KiB Swap: 0 total, 0 free sh bash 5.1_p16-r6 ld GNU ld (Gentoo 2.42 p3) 2.42.0 dev-lang/python: 3.12.3::gentoo sys-devel/binutils: 2.42-r1::gentoo sys-kernel/linux-headers: 6.6-r1::gentoo (virtual/os-headers) Repositories: Binary Repositories: gentoobinhost priority: 1 sync-uri: https://distfiles.gentoo.org/releases/x86/binpackages/23.0/i686 ACCEPT_LICENSE="* -@EULA" CFLAGS="-O2 -march=i686 -pipe" CONFIG_PROTECT="/etc /usr/share/gnupg/qualified.txt" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/gentoo-release /etc/sandbox.d" CXXFLAGS="-O2 -march=i686 -pipe" DISTDIR="/var/cache/distfiles" FEATURES="assume-digests binpkg-docompress binpkg-dostrip binpkg-logs binpkg-multi-instance buildpkg-live config-protect-if-modified distlocks ebuild-locks fixlafiles ipc-sandbox merge-sync merge-wait multilib-strict network-sandbox news parallel-fetch pid-sandbox pkgdir-index-trusted preserve-libs protect-owned qa-unresolved-soname-deps sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync xattr" GENTOO_MIRRORS="http://distfiles.gentoo.org" PKGDIR="/var/cache/binpkgs" PORTAGE_TMPDIR="/var/tmp" USE="" Unset: ACCEPT_KEYWORDS, CHOST, EMERGE_DEFAULT_OPTS, ENV_UNSET, PORTAGE_BINHOST, PORTAGE_BUNZIP2_COMMAND ================================================================= Package Settings ================================================================= sys-libs/glibc-2.39-r6::gentoo was built with the following: USE="abi_x86_32 elibc_glibc kernel_linux multiarch ssp static-libs x86 -audit -caps -cet -compile-locales -custom-cflags -doc -gd -hash-sysv-compat -headers-only -multilib -multilib-bootstrap -nscd -perl -profile -selinux -stack-realign -suid -systemd -systemtap -test -vanilla" CHOST="i686-pc-linux-gnu" CFLAGS="-O2 -march=i686 -pipe -fcf-protection=none" CXXFLAGS="-O2 -march=i686 -pipe -fcf-protection=none" FEATURES="strict protect-owned unmerge-orphans userpriv multilib-strict parallel-fetch config-protect-if-modified unmerge-logs buildpkg-live pkgdir-index-trusted binpkg-multi-instance merge-wait preserve-libs userfetch fixlafiles ebuild-locks network-sandbox qa-unresolved-soname-deps assume-digests sfperms distlocks unknown-features-warn merge-sync sandbox binpkg-logs usersync clean-logs binpkg-docompress parallel-install ipc-sandbox buildpkg binpkg-dostrip pid-sandbox usersandbox" LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,-z,pack-relative-relocs"

Created attachment 895331 [details] glibc-2.39-r6-build.log Some some further testing I have found this is a requirement of SSE2, you can confirm this in QEMU by using -cpu pentium3,+sse2 as the CPU type which matches what iamben has said above as both althon and core2duo in QEMU have this enabled. (A real AlthonXP will likely fail as not many had sse2 enabled though) So far I have found none of the 2.38 are affected by this and know 2.39-r2 does work as I'm running that on a Pentium2 system, so this gives us a rough timeline of when the breakage happened. The log provided is built on read hardware and running readelf shows x86-64-baseline and x86-64-v3 ISAs are be selected even on a full x86 system. # readelf -n libc.so && readelf -n elf/ld-linux.so.2 Displaying notes found in: .note.gnu.property Owner Data size Description GNU 0x00000024 NT_GNU_PROPERTY_TYPE_0 Properties: x86 ISA needed: x86-64-baseline x86 feature used: x86, x87, XMM x86 ISA used: x86-64-baseline Displaying notes found in: .note.ABI-tag Owner Data size Description GNU 0x00000010 NT_GNU_ABI_TAG (ABI version tag) OS: Linux, ABI: 3.2.0 Displaying notes found in: .note.gnu.property Owner Data size Description GNU 0x00000018 NT_GNU_PROPERTY_TYPE_0 Properties: x86 feature used: x86, x87, FXSR, XSAVE, XSAVEC x86 ISA used: x86-64-baseline, x86-64-v3

Created attachment 895370 [details, diff] Cause - 0041-x86-Define-MINIMUM_X86_ISA_LEVEL-in-config.h-BZ-3167.patch I found the breakage started at 2.39-r4 which shows 0041-x86-Define-MINIMUM_X86_ISA_LEVEL-in-config.h-BZ-3167.patch as the offender, removing this patch allows glibc to work as it did previously. As discussed on #gentoo-toolchain, this isn't within my skillset to fix however I hope this is all the information someone else needs to do the final fix.
We made some progress in #gentoo-toolchain earlier with awilfox (thanks!). Filed upstream at https://sourceware.org/bugzilla/show_bug.cgi?id=31867.
With stage3-i686-openrc-20240603T164904Z.tar.xz, with no changes: ``` x86 ~ # readelf -n /lib/ld-linux.so.2 Displaying notes found in: .note.gnu.property Owner Data size Description GNU 0x00000018 NT_GNU_PROPERTY_TYPE_0 Properties: x86 feature used: x86, FXSR, XSAVE, XSAVEC x86 ISA used: x86-64-baseline, x86-64-v3 ``` After rebuilding glibc with no changes: ``` x86 ~ # readelf -n /lib/ld-linux.so.2 Displaying notes found in: .note.gnu.property Owner Data size Description GNU 0x00000018 NT_GNU_PROPERTY_TYPE_0 Properties: x86 feature used: x86, FXSR, XSAVE, XSAVEC x86 ISA used: x86-64-baseline, x86-64-v3 ``` After rebuilding with a candidate patch from awilfox: ``` # readelf -n /lib/ld-linux.so.2 Displaying notes found in: .note.gnu.property Owner Data size Description GNU 0x00000018 NT_GNU_PROPERTY_TYPE_0 Properties: x86 feature used: x86, FXSR, XSAVE, XSAVEC x86 ISA used: x86-64-baseline, x86-64-v3 ```
At the moment, I think awilfox's patch is probably right, but not sufficient. I'm looking at where the v3 marker comes from. Reverting the patch immolo mentions doesn't seem to help me.
awilfox's posted the patch: https://inbox.sourceware.org/libc-alpha/20240609133933.62366-1-AWilcox@Wilcox-Tech.com/T/#u.

I've tested the upstream patch https://sourceware.org/bugzilla/attachment.cgi?id=15573&action=diff&collapsed=&headers=1&format=raw by H.J. Lu and found the following. On my Pentium 3 machine I have confirmed this fixes the issue. Enabling tests causes one fail in localedata/sort-test but I'm fairly confident this is known issue which doesn't matter to the patch in question.

I just tried "install-x86-minimal-20240614T123642Z.iso" and encountered the following error message. [ 2024-06-14 22:41:16.807353 ] [!!] init (/sbin/init) not found in mounted root device (UNKNOWN)! A different machine that I updated to "glibc-2.39-r9" also showed the same message, thus became unbootable.

I feel like that's a coincidence given the above?
(In reply to Sam James from comment #19) > I feel like that's a coincidence given the above? Most likely yes. I'll wait for the next ISO build.
I have a theory as to why your existing setup broke. 1) The ISO is just broken like it was before (so it's just not fixed in there yet, as glibc-2.39-r9 isn't in there). 2) While it can't happen if you do the whole thing natively on a previously working setup because of the glibc sanity check -> you never get a bad point, I think it can happen if 2a) you build binpkgs for an x86 system where a bad glibc is produced but works on that machine (w/ SSE2) 2b) you install the fixed version of glibc (via binpkg or not, doesn't matter as the sanity check passes) 2c) you install a coreutils binpkg built against bad glibc OR your coreutils was already built against a bad glibc (and now it becomes broken because the commit immolo identified before is what makes ld.so abort early) Maybe. We'll see...
20240614T220409Z <= this should be the first "good" x86 upload again Also, if you use binary packages from our mirrors, make sure they have been built after that ^ timestamp (and you deleted local copies of old ones). The old ones should get removed from the mirrors automatically, however, that can take time...
After installing "glibc-2.39-r9", I somehow managed to break "env" command, which prevents me from installing many other packages. # env env: CPU ISA level is lower than required If there is an easy fix, I'd like to try, before wiping out and starting from scratch.

Let me list my rough thoughts on what we do next, then we can try figure out what the best thing for you to try is: * Obviously, we'll do a news item shortly (next day or two hopefully) once we're clear this definitely works & we have fixed media * Several suboptions (do we do some? all?) ** Instruct x86 users to run a command which strips the x86 ISA marker notes as a one-off (I need to play with the most elegant way of doing this) ** We put out a patched glibc with the revert for the ld.so abort (so it ignores the ISA markers temporarily) on x86 ** We tell users to install clean binpkgs when they're available ** ???

That sure doesn't look like an easy fix, and I couldn't put my system offline long, so I went ahead and started from scratch with "install-x86-minimal-20240614T220409Z.iso" and "stage3-i486-openrc-20240614T220409Z.tar.xz". It did solve the problem, although it's more of a cowardly solution. At least the system is up and running.
I have another x86 system that had the same problem, but I left it alone, lest I'd break it. I finally updated, and the process went smoothly. No issues.
