hurd: Fix local PLT
|
|
|
00c0d4 |
|
|
|
00c0d4 |
* include/sys/random.h (__getrandom): Add hidden prototype.
|
|
|
00c0d4 |
* stdlib/getrandom.c (getrandom): Rename to hidden definition __getrandom.
|
|
|
00c0d4 |
Add weak alias.
|
|
|
00c0d4 |
* sysdeps/mach/hurd/getrandom.c (getrandom): Likewise.
|
|
|
00c0d4 |
* sysdeps/unix/sysv/linux/getrandom.c (getrandom): Likewise.
|
|
|
00c0d4 |
* sysdeps/mach/hurd/getentropy.c (getentropy): Use __getrandom instead of
|
|
|
00c0d4 |
getrandom.
