[ Upstream commit e78e274eb22d966258a3845acc71d3c5b8ee2ea8 ]
When built with Control Flow Integrity, function prototypes between caller and function declaration must match. These mismatches are visible at compile time with the new -Wcast-function-type-strict in Clang[1].
There were 97 warnings produced by NFS. For example:
fs/nfsd/nfs4xdr.c:2228:17: warning: cast from '__be32 (*)(struct nfsd4_compoundargs *, struct nfsd4_access *)' (aka 'unsigned int (*)(struct nfsd4_compoundargs *, struct nfsd4_access *)') to 'nfsd4_dec' (aka 'unsigned int (*)(struct nfsd4_compoundargs *, void *)') converts to incompatible function type [-Wcast-function-type-strict] [OP_ACCESS] = (nfsd4_dec)nfsd4_decode_access, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The enc/dec callbacks were defined as passing "void *" as the second argument, but were being implicitly cast to a new type. Replace the argument with union nfsd4_op_u, and perform explicit member selection in the function body. There are no resulting binary differences.
Changes were made mechanically using the following Coccinelle script, with minor by-hand fixes for members that didn't already match their existing argument name:
@find@ identifier func; type T, opsT; identifier ops, N; @@
opsT ops[] = { [N] = (T) func, };
@already_void@ identifier find.func; identifier name; @@
func(..., -void +union nfsd4_op_u *name) { ... }
@proto depends on !already_void@ identifier find.func; type T; identifier name; position p; @@
func@p(..., T name ) { ... }
@script:python get_member@ type_name << proto.T; member; @@
coccinelle.member = cocci.make_ident(type_name.split("_", 1)[1].split(' ',1)[0])
