2022-12-11ocfs2: always read both high and low parts of dinode link countAlexey Asemov
When filesystem is using indexed-dirs feature, maximum link count values can spill over to i_links_count_hi, up to OCFS2_DX_LINK_MAX links. ocfs2_read_links_count() checks for OCFS2_INDEXED_DIR_FL flag in dinode, but this flag is only valid for directories so for files the check causes high part of the link count not being read back from file dinodes resulting in wrong link count value when file has >65535 links. As ocfs2_set_links_count() always writes both high and low parts of link count, the flag check on reading may be removed.

2022-12-10NFSD: Avoid clashing function prototypesKees Cook
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]) @convert@ identifier find.func; type proto.T; identifier proto.name; position proto.p; identifier get_member.member; @@ func@p(..., - T name + union nfsd4_op_u *u ) { + T name = &u->member; ... } @cast@ identifier find.func; type T, opsT; identifier ops, N; @@ opsT ops[] = { [N] = - (T) func, }; Cc: Chuck Lever <chuck.lever@oracle.com> Cc: Jeff Layton <jlayton@kernel.org> Cc: Gustavo A.

2022-12-10SUNRPC: Fix crasher in unwrap_integ_data()Chuck Lever
If a zero length is passed to kmalloc() it returns 0x10, which is not a valid address. gss_verify_mic() subsequently crashes when it attempts to dereference that pointer. Instead of allocating this memory on every call based on an untrusted size value, use a piece of dynamically-allocated scratch memory that is always available.
