It isn't enough. First, files named somelib are ignored because they don't look
like libraries. I asked for the exact situation, not some general idea.
Second, even if I'm using a real library with its real name and then a link I
see no accesses outside the chroot:
I copied libc.so in a chroot tree and added libc.so.6 as a symlink. The only
accesses to libc.so of
ldconfig -r $PWD/testroot
are:
lstat("$PWD/testroot/lib64/libc.so", {st_mode=S_IFREG|0775, st_size=9166760,
...}) = 0
open("$PWD/testroot/lib64/libc.so", O_RDONLY) = 4
stat("$PWD/testroot/lib64/libc.so.6", {st_mode=S_IFREG|0775, st_size=9166760,
...}) = 0
lstat("$PWD/testroot/lib64/libc.so.6", {st_mode=S_IFLNK|0777, st_size=7, ...}) = 0
readlink("$PWD/testroot/lib64/libc.so.6", "libc.so", 4096) = 7
lstat("$PWD/testroot/lib64/libc.so", {st_mode=S_IFREG|0775, st_size=9166760,
...}) = 0
lstat("$PWD/testroot/lib64/libc.so.6", {st_mode=S_IFLNK|0777, st_size=7, ...}) = 0
lstat("$PWD/testroot/lib64/libc.so.6", {st_mode=S_IFLNK|0777, st_size=7, ...}) = 0
readlink("$PWD/testroot/lib64/libc.so.6", "libc.so", 4096) = 7
lstat("$PWD/testroot/lib64/libc.so", {st_mode=S_IFREG|0775, st_size=9166760,
...}) = 0
stat("$PWD/testroot/lib64/libc.so", {st_mode=S_IFREG|0775, st_size=9166760,
...}) = 0
lstat("$PWD/testroot/lib64/libc.so", {st_mode=S_IFREG|0775, st_size=9166760,
...}) = 0
write(3, "libc.so.6\0/lib64/libc.so.6\0", 27) = 27
I have of course replace the real path with $PWD in the output. But as you can
see there is no access outside the chroot.
Either provide _exact_ instructions for how to show the problem or close the
bug. And make sure you're using current sources.
