Mathias Krause authoredThree errors resulting in kernel memory disclosure: 1/ The structures used for the netlink based crypto algorithm report API are located on the stack. As snprintf() does not fill the remainder of the buffer with null bytes, those stack bytes will be disclosed to users of the API. Switch to strncpy() to fix this. 2/ crypto_report_one() does not initialize all field of struct crypto_user_alg. Fix this to fix the heap info leak. 3/ For the module name we should copy only as many bytes as module_name() returns -- not as much as the destination buffer could hold. But the current code does not and therefore copies random data from behind the end of the module name, as the module name is always shorter than CRYPTO_MAX_ALG_NAME. Also switch to use strncpy() to copy the algorithm's name and driver_name. They are strings, after all. Signed-off-by:

sub usage() {
print <<EOT;
$0 [-f] [-n] <source> <dest>
$0 [-f] [-k] [-n] <source> ... <dest directory>
In the first form, source must exist and be either a file,
symlink or directory, dest must not exist. It renames source to dest.
In the second form, the last argument has to be an existing
directory; the given sources will be moved into this directory.
Updates the git cache to reflect the change.
Use "git commit" to make the change permanently.
Options:
-f Force renaming/moving, even if target exists
-k Continue on error by skipping
not-existing or not revision-controlled source
-n Do nothing; show what would happen
