.SH DESCRIPTION
|
|
|
|
Long ago it was considered safe to have encrypted passwords openly
|
2007-04-12 22:42:49 +00:00
|
|
|
visible in the password file.
|
|
|
|
When computers got faster and people
|
2004-11-03 13:51:07 +00:00
|
|
|
got more security-conscious, this was no longer acceptable.
|
|
|
|
Julianne Frances Haugh implemented the shadow password suite
|
|
|
|
that keeps the encrypted passwords in
|
2005-07-04 08:59:13 +00:00
|
|
|
the shadow password database
|
2007-04-12 22:42:49 +00:00
|
|
|
(e.g., the local shadow password file
|
2004-11-03 13:51:07 +00:00
|
|
|
.IR /etc/shadow ,
|
2005-07-04 08:59:13 +00:00
|
|
|
NIS, and LDAP),
|
2004-11-03 13:51:07 +00:00
|
|
|
readable only by root.
|
|
|
|
.LP
|
2005-07-04 08:59:13 +00:00
|
|
|
The functions described below resemble those for
|
|
|
|
the traditional password database
|
|
|
|
(e.g., see
|
|
|
|
.BR getpwnam (3)
|
|
|
|
and
|
|

.BR getpwent (3)).

are not thread-safe. And
* putspent(),

getspnam.3: ATTRIBUTES: Note functions that are/aren't thread-safe
After research, We think
* getspnam(),
* getspent(),
* setspent(),
* endspent(),
* getspent_r(),
* fgetspent(),
* sgetspent(),
are not thread-safe. And
* putspent(),
* getspnam_r(),
* sgetspent_r(),
* lckpwdf(),
* ulckpwdf(),
* fgetspent_r(),
are thread-safe. But, there are not
markings of them in glibc document.
