Subject: [PATCH] uapi: fix asm/signal.h userspace compilation errors
Date: Sun, 26 Feb 2017 04:01:56 +0300 [thread overview]
Message-ID: <20170226010156.GA28831@altlinux.org> (raw)
Include <stddef.h> (guarded by #ifndef __KERNEL__) to fix asm/signal.h
userspace compilation errors like this:
/usr/include/asm/signal.h:126:2: error: unknown type name 'size_t'
size_t ss_size;
As no uapi header provides a definition of size_t, inclusion
of <stddef.h> seems to be the most conservative fix available.
On the kernel side size_t is typedef'ed to __kernel_size_t, so
an alternative fix would be to change the type of sigaltstack.ss_size
from size_t to __kernel_size_t for all architectures except those where
sizeof(size_t) < sizeof(__kernel_size_t), namely, x32 and mips n32.
On x32 and mips n32, however, #include <stddef.h> seems to be the most
straightforward way to obtain the definition for sigaltstack.ss_size's
type.

Subject: [PATCH] uapi: fix asm/signal.h userspace compilation errors
