PSID length is de-facto always 32 alphanumeric characters.
Limit the read of PSID from keyfile to this limit
(if not set by explicit size option).
This eliminates mistakes when the keyfile contains EOL characters.
Also, some OPAL drives accepts PSID with any suffix, this patch
unifies processing (it works everywhere the same).
There is no need to unlock keyslot if the provided name
has wrong format. Let's check for length and '/' in name early.
Note that other commands could accept path to the device
as libdevmapper translate it to the name (status /dev/mapper/xxx).
Add early check only to activate commands.
It still can fail later because of mangled characters.
Fixes: #893
This patch switches code to SPDX one-line license identifiers according to
https://spdx.dev/learn/handling-license-info/
and replacing long license text headers.
I used C++ format on the first line in style
// SPDX-License-Identifier: <id>
except exported libcryptsetup.h, when only C comments are used.
The only additional changes are:
- switch backend utf8.c from LGPL2+ to LGPL2.1+ (as in systemd)
- add some additional formatting lines.
This should silence similar warnings like
warning: cast from 'char *' to 'struct xyz *' increases required alignment from 1 to X
when we try to calclulate byte pointer offsets in a buffer.
