Bug#755580: src:glibc: drop libgcc dependency from stage2 builds
Package: src:glibc
Version: 2.19-7
Severity: wishlist
Tags: patch
User: helm...@debian.org
Usertags: rebootstrap
Even if one manages to build glibc with profiles stage1 or stage2, the
results are not installable due to unmet dependencies. The following
issues occur:
* stage1 libc6-dev Depends on libc6 which is not built in stage1
* stage2 libc6 Depends on libgcc1 which is not built by gcc stage2
This bug shall only cover the second (easier) part and I shall report a
different bug for the first issue at a later time.
When we briefly discussed this issue, there was consensus that substvars
would be the tool to address it. So the attached patch turns those
libgcc dependencies into ${libgcc:Depends} and suppresses them for
stage2. It's a bit unfortunate that dependency information keeps
scattering over control and rules.d/debhelper.mk, but I didn't find a
better way.

This is triggered by the cache miss that occurs when I try to resolve
the machine's hostname (e.g., getent ahosts oxylus).

So the gaih_addrtuple linked list is corrupted somehow.
I removed 'myhostname' from the 'hosts' definition in
/etc/nsswitch.conf, and having restarted nscd and invalidating the hosts
cache, I could no longer reproduce the crash. Re-enabling 'myhostname',
invalidating the cache and restarting nscd causes the crash to re-occur.

Bug#755734: libc-bin - ldconfig fails if dirent-d_type is not correct
Package: libc-bin Version: 2.19-7 Severity: normal ldconfig uses the d_type field in the readdir(2) result as optimization. If the field wrongly identifies symlinks as regular files, ldconfig assumes that lstat(2) returns the same than stat(2) and aborts if it is not the case. It does - call lstat, use this information to search the cache, - call stat in readelf.c#process_file and override the old information, - try to insert the new entry; this entry already exists and it calls abort. The 9p filesystem wrongly reports symlinks as regular files, so it triggers this condition.
