Bug ID: 57996
Summary: Symlinks erroneously not followed when target inode
number >32 bits
Product: Apache httpd-2
Version: 2.4.10
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2

Fix resolve_symlink() target inode number overflow failure
When running httpd on 32-bit x86, some (but not all) symbolic links are neither
followed nor shown in the directory index. Attempts to follow them result in
error AH00037 being logged. The configuration permits following symlinks if the
owner matches.
On investigation, it appeared that the problematic symlinks are those where the
link has an inode number that fits within 32 bits but the target does not.
I have developed a patch and successfully tested it on top of httpd 2.4.10 as
packaged in Debian 8. Inspection of the head of the 2.4 branch in svn suggests
that the bug is still present there.
