Subject: Crash by update of shared libraries
Date: Tue, 18 Feb 2014 20:54:23 +0100 [thread overview]
Message-ID: <5303BA6F.9090704@enst-bretagne.fr> (raw)
Hello,
my system crash by libraries update. Some steps to reproduce the
bug (without crash of the all system):
$ export LD_PRELOAD=./libfake.so.1
$ cp libfake.so.1 /tmp/
$ cp /tmp/libfake.so.1 .
=> Bus error
The cp crash, since the file of the loaded library changed (and the copy
failed of course, the new file is now empty).
All software with a library loaded (with ld) will crash as well (for
example by system updating of the libc: the pid 1 will crash).
Tested on a Linux kernel 3.14.0-rc3.
Regards,
--
Florent.
