In attempting to enable building various part of Android with -Wall -Werror, we found that the const security_context_t declarations in libselinux are incorrect; const char * was intended, but const security_context_t translates to char * const and triggers warnings on passing const char * from the caller. Easiest fix is to replace them all with const char *. And while we are at it, just get rid of all usage of security_context_t itself as it adds no value - there is no true encapsulation of the security context strings and callers already directly use string functions on them. typedef left to permit building legacy users until such a time as all are updated. This is a port of Change-Id I2f9df7bb9f575f76024c3e5f5b660345da2931a7 from Android, augmented to deal with all of the other code in upstream libselinux and updating the man pages too.

.SH "DESCRIPTION"
|
|
.BR getfilecon ()
|
|
retrieves the context associated with the given path in the file system, the
|
|
length of the context is returned.
|
|
|
|
.BR lgetfilecon ()
|
|
is identical to
|
|
.BR getfilecon (),
|
|
except in the case of a symbolic link, where the
|
|
link itself is interrogated, not the file that it refers to.
|
|
|
|
.BR fgetfilecon ()
|
|
is identical to
|
|
.BR getfilecon (),
|
|
only the open file pointed to by filedes (as returned by
|
|
.BR open (2))
|
|
is interrogated in place of path.
|
|
|
|
.BR getfilecon_raw (),
|
|
.BR lgetfilecon_raw ()
|
|
and
|
|
.BR fgetfilecon_raw ()
|
|
behave identically to their non-raw counterparts but do not perform context
|
|
translation.
|
|
|
|
The returned context should be freed with
|
|
.BR freecon (3)
|
|
if non-NULL.
|
|
.
|
|
.SH "RETURN VALUE"
|
|
On success, a positive number is returned indicating the size of the
|
|
extended attribute value. On failure, \-1 is returned and
|
|
.I errno
|
|
is set appropriately.
|
|
|
|
If the context does not exist, or the process has no access to
|
|
this attribute,
|
|
.I errno
|
|
is set to
|
|
.BR ENODATA .
|
|
|
|
If extended attributes are not supported by the filesystem, or are
|
|
disabled,
|
|
.I errno
|
|
is set to
|
|
.BR ENOTSUP .
|
|
|
|
The errors documented for the
|
|
.BR stat (2)
|
|
system call are also applicable here.
