So the regression tests are looking good so far. I'm currently still verifying that the regression with the linux kernel on Intel (404s) is fixed with 4.15.0-136.140 (from -proposed). If that works out, I'll copy the packages to the archive for verification by the SRU team.
I've SRU'ifyed the description of this bug report. Is there any more specific test case you could give to verify that this bug is indeed fixed? How to reproduce those "random errors and infinite loops"? ** Description changed: - Please backport the following bugfix into Ubuntu LTS: - https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=e6213e09ed0e + [Impact] + + * In s390 kernel context, this bug manifests itself as random errors + and infinite loops. + + [Test Case] + + * Needs to be confirmed by IBM + * Build-time tests-suite (applied upstream) backported to Bionic in + + ld/testsuite/ld-s390/gotreloc-1.s + + ld/testsuite/ld-s390/gotreloc-1.ver + + ld/testsuite/ld-s390/gotreloc_31-1.dd + + ld/testuite/ld-s390/gotreloc_64-1.dd + + [Where problems could occur] + + * Binutils is a base toolchain package + - A problem could potentially affect the whole system + - With compiler/linker errors + - Or random errors in the produced binaries + * This patch touches only architecture specific code in bfd/elf64-s390.c + - It would only affect the s390x architecture in this case + + [Other Info] + + * While testing the fix in Bileto, we found one pending autopkgtest regression with linux/amd64 4.15.0-135.139 which is resolved in 4.15.0-136.140 (currently in -proposed). + + + == Original Description == + Please backport the following bugfix into Ubuntu LTS: https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=e6213e09ed0e Some relevant historic links: Debian bugreport: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=961736 glibc bugreport: https://sourceware.org/bugzilla/show_bug.cgi?id=18960 In s390 kernel context, this bug manifests itself as random errors and infinite loops, so it's fairly severe.
