Bug#994232: libc6: generates unnecessarily tight dependencies on mips, mipsel
Package: libc6
Version: 2.32-2
Severity: normal
Tags: patch
X-Debbugs-Cc: debian-release@lists.debian.org
Most architectures' libc6.symbols.$arch have this pattern:
> $ cat debian/libc6.symbols.i386
> #include "libc6.symbols.common"
> ld-linux.so.2 #PACKAGE# #MINVER#
> #include "symbols.wildcards"
> libc.so.6 #PACKAGE# #MINVER#
> #include "symbols.wildcards"
This results in any use of symbols versioned foo@GLIBC_2.23 generating a
dependency on libc6 (>= 2.23), and so on.
However, libc6:mips and libc6:mipsel are missing the final
'#include "symbols.wildcards"', which results in those architectures
generating an unnecessarily strict dependency on libc6 (>= 2.32-1) and
entangling other transitions with glibc's transition. As far as I can see,
this was accidental?
libc6-i386:x32 has the same issue.
Please consider the attached patch.

Subject: [PATCH] Restore versioned symbol tracking for mips, mipsel,
libc6-i386:x32
Commit d3f9fade "debian/libc6.symbols.mips, debian/libc6.symbols.mipsel:
drop symbol overrides for TLS support" accidentally removed the inclusion
of symbols.wildcards, resulting in all symbols in libc.so.6 on the
affected architectures generating an unnecessarily tight dependency on
libc6 (>= 2.32-1).
Commit 5f5dfcb0 caused an equivalent issue for libc6-i386:x32.
Fixes: d3f9fade "debian/libc6.symbols.mips, debian/libc6.symbols.mipsel: drop symbol overrides for TLS support."
Fixes: 5f5dfcb0 "debian/libc6-i386.symbols.x32, debian/libc6.symbols.i386: drop symbol overrides for TLS support.
