|

|
||||
`selinux_check_passwd_access_internal()`, and thereby
|
||||
`checkPasswdAccess(3)` and `selinux_check_passwd_access(3)`, does not
|
||||
respect the policy defined setting of `deny_unknown`, like
|
||||
`selinux_check_access(3)` does.
|
||||
This means in case the security class `passwd` is not defined, success
|
||||
is returned instead of failure, i.e. permission denied.
|
||||
|
||||
Most policies should define the `passwd` class and the two affected
|
||||
public functions are marked deprecated.
|
||||
|
||||
Align the behavior with `selinux_check_access(3)` and respect
|
||||
the deny_unknown setting in case the security class is not defined.

When building libselinux on Fedora 33 with gcc 10.3.1, the compiler
|
||||
reports:
|
||||
|
||||
label_file.c: In function ‘lookup_all.isra’:
|
||||
label_file.c:940:4: error: ‘strncpy’ specified bound depends on the
|
||||
length of the source argument [-Werror=stringop-overflow=]
|
||||
940 | strncpy(clean_key, key, len - 1);
|
||||
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
label_file.c:927:8: note: length computed here
|
||||
927 | len = strlen(key);
|
||||
| ^~~~~~~~~~~
|
||||
cc1: all warnings being treated as errors
|
||||
|
||||
As clean_key is the result of malloc(len), there is no issue here. But
|
||||
using strncpy can be considered as strange, because the size of the
|
||||
string is already known and the NUL terminator is always added later, in
|
||||
function ‘lookup_all.isra.
|
||||
|
||||
Replace strncpy with memcpy to silence this gcc false-positive warning.

Open the file stream with the `e` flag, so that the underlying file

Also drop the flag `b`, since it is ignored on POSIX systems.
