Do not make symbols hidden on Blackfin
|
||||
|
||||
The libselinux logic to hide internal symbols from the DSO doesn't
|
||||
work properly on Blackfin due to the USER_LABEL_PREFIX not being
|
||||
handled properly. A real fix is not that simple, so this patch simply
|
||||
disables the internal symbol hiding mechanism. This means that those
|
||||
symbols are visible in the final DSO, which is not a problem for
|
||||
proper execution, it just isn't as clean.

fix undefined macros in musl
|
||||
|
||||
musl does not define glibc-specific macros, so use a simple version of
|
||||
the macro when it is not defined.
|
||||
|
||||
This is very inefficient, however, but copying the code from glibc is
|
||||
not really possible because it is LGPL while libselinux in Public
|
||||
Domain, and we want to avoid license propagation, so this macro is
|
||||
completely written from scratch, and non-optimal.

libselinux is the runtime SELinux library that provides
|
||||
interfaces (e.g. library functions for the SELinux kernel
|
||||
APIs like getcon(), other support functions like
|
||||
getseuserbyname()) to SELinux-aware applications. libselinux
|
||||
may use the shared libsepol to manipulate the binary policy
|
||||
if necessary (e.g. to downgrade the policy format to an
|
||||
older version supported by the kernel) when loading policy.
