This sounds like a bug

which part?
if you think we should be using an older version of glibc for aarch64 i'd be happy to test it out and submit a PR! i already have the toolchain building, etc

I think we should use 2.17 for the toolchain instead of 2.23

i'd be happy to follow up on that! i also wanna highlight that the automatic dependencies may be a problem to consider for osquery build? apparently cpack by default leaves the rpm auto dependency feature enabled: http://ftp.rpm.org/max-rpm/s1-rpm-depend-auto-depend.html and there's two issues i see: • the environment the package is built in determines the automatic dependencies, so this may cause some concern for 
osquery-packaging
if the build environment isn't the same • we're already manually specifying requirements, so we end up with things like the automatic glibc versions and manually specified ones
here's the requirements list for the 4.7.0 aarch64 package, so you can see what i mean about the second point:
Copy code
rpm -qp --requires osquery-4.7.0-1.linux.aarch64.rpm
/bin/sh
/bin/sh
/bin/sh
/bin/sh
/bin/sh
/usr/bin/env
config(osquery) = 4.7.0-1.linux
glibc >= 2.12
ld-linux-aarch64.so.1()(64bit)
ld-linux-aarch64.so.1(GLIBC_2.17)(64bit)
libc.so.6()(64bit)
libc.so.6(GLIBC_2.17)(64bit)
libc.so.6(GLIBC_2.18)(64bit)
libdl.so.2()(64bit)
libdl.so.2(GLIBC_2.17)(64bit)
libm.so.6()(64bit)
libm.so.6(GLIBC_2.17)(64bit)
libpthread.so.0()(64bit)
libpthread.so.0(GLIBC_2.17)(64bit)
libresolv.so.2()(64bit)
libresolv.so.2(GLIBC_2.17)(64bit)
librt.so.1()(64bit)
libz.so.1()(64bit)
libz.so.1(ZLIB_1.2.0)(64bit)
libz.so.1(ZLIB_1.2.2)(64bit)
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(FileDigests) <= 4.6.0-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1

ah good catch! I guess 
CPACK_RPM_PACKAGE_AUTOREQ
should help with this

yeah! i think cpack has one that also disabled AUTODEP? i'm not sure what the difference is, but i do recall seeing two flags

autoreq is 
May be used to enable (1, yes) or disable (0, no) automatic shared libraries dependency detection. Dependencies are added to requires list.

but i wasn't sure if we wanted to disable autoreq entirely and simply update the aarch64 static requirements. i've never used it, and it seems kinda horrifying

I mean, even for x86_64 I think we want only the bare minimum at the minimum version we use.

yeah that's what i was thinking. and it makes it much easier if we don't need to use the toolchain in 
osquery-packaging

yeah definitely, osquery-packaging shouldn't depend on it since it acts on already compiled binaries. At least we weren't planning to.

i'm already pretty deep into this, so i'd be happy to get 2 PRs together this week, one to disable autoreq and one to downgrade the aarch64 toolchain to 2.17; let me know if you find anything else out!
