Source: glibc
Version: 2.27-6
Severity: important
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512
Reproduction:
$ strace -ELD_PRELOAD='/sss/${PLATFORM}/dddd' -s300 /bin/cat
execve("/bin/cat", ["/bin/cat"], 0x55ddc6b820f0 /* 64 vars */) = 0
brk(NULL) = 0x56046d9c1000
access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory)
readlink("/proc/self/exe", "/bin/cat", 4096) = 8
openat(AT_FDCWD, "/sss/x86_64/dddd", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
writev(2, [{iov_base="ERROR: ld.so: object '", iov_len=22}, {iov_base="/sss/${PLATFORM}/dddd", iov_len=21}, {iov_base="' from ", iov_len=7}, {iov_base="LD_PRELOAD", iov_len=10}, {iov_base=" cannot be preloaded (", iov_len=22}, {iov_base="cannot open shared object file", iov_len=30}, {iov_base="): ignored.\n", iov_len=12}], 7ERROR: ld.so: object '/sss/${PLATFORM}/dddd' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
) = 124
So $PLATFORM is not expanded. This is a regression from 2.24
According to
https://sourceware.org/bugzilla/show_bug.cgi?id=22299
it *should* be fixed in 2.27, but it is clerly still reproducible in
debian testing/sid.
This is causing the following problem for me:
