From 609c9d0951da387cd523b5db42a82d38dabc37c4 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Thu, 29 Sep 2022 16:18:06 -0300 Subject: malloc: Do not clobber errno on __getrandom_nocancel (BZ #29624) Use INTERNAL_SYSCALL_CALL instead of INLINE_SYSCALL_CALL. This requires emulate the semantic for hurd call (so __arc4random_buf uses the fallback). Checked on x86_64-linux-gnu.
