SUNRPC: Remove broken gss_mech_list_pseudoflavors()

2020-01-15T15:54:32+00:00

Remove gss_mech_list_pseudoflavors() and its callers. This is part of an unused API, and could leak an RCU reference if it were ever called. Signed-off-by: Trond Myklebust Signed-off-by: Anna Schumaker

sunrpc: remove KERNEL ifdefs

2019-11-12T16:43:29+00:00

Remove the __KERNEL__ ifdefs from the non-UAPI sunrpc headers, as those can't be included from user space programs. Signed-off-by: Christoph Hellwig Signed-off-by: J. Bruce Fields

SUNRPC: Add rpc_auth::au_ralign field

2019-02-14T16:48:36+00:00

Currently rpc_inline_rcv_pages() uses au_rslack to estimate the size of the upper layer reply header. This is fine for auth flavors where au_verfsize == au_rslack. However, some auth flavors have more going on. krb5i for example has two more words after the verifier, and another blob following the RPC message. The calculation involving au_rslack pushes the upper layer reply header too far into the rcv_buf. au_rslack is still valuable: it's the amount of buffer space needed for the reply, and is used when allocating the reply buffer. We'll keep that. But, add a new field that can be used to properly estimate the location of the upper layer header in each RPC reply, based on the auth flavor in use.

SUNRPC: Make AUTH_SYS and AUTH_NULL set au_verfsize

2019-02-14T16:17:47+00:00

au_verfsize will be needed for a non-flavor-specific computation in a subsequent patch. Signed-off-by: Chuck Lever Signed-off-by: Anna Schumaker

SUNRPC: Use struct xdr_stream when decoding RPC Reply header

2019-02-14T14:11:18+00:00

Modernize and harden the code path that parses an RPC Reply message. Signed-off-by: Chuck Lever Signed-off-by: Anna Schumaker

SUNRPC: Use struct xdr_stream when constructing RPC Call header

2019-02-13T18:45:17+00:00

Modernize and harden the code path that constructs each RPC Call message. Signed-off-by: Chuck Lever Signed-off-by: Anna Schumaker

SUNRPC discard cr_uid from struct rpc_cred.

2018-12-19T18:52:46+00:00

Just use ->cr_cred->fsuid directly. Signed-off-by: NeilBrown Signed-off-by: Anna Schumaker

SUNRPC: remove crbind rpc_cred operation

2018-12-19T18:52:46+00:00

This now always just does get_rpccred(), so we don't need an operation pointer to know to do that. Signed-off-by: NeilBrown Signed-off-by: Anna Schumaker

SUNRPC: remove generic cred code.

2018-12-19T18:52:46+00:00

This is no longer used. Signed-off-by: NeilBrown Signed-off-by: Anna Schumaker

NFS/NFSD/SUNRPC: replace generic creds with 'struct cred'.

2018-12-19T18:52:46+00:00

SUNRPC has two sorts of credentials, both of which appear as "struct rpc_cred". There are "generic credentials" which are supplied by clients such as NFS and passed in 'struct rpc_message' to indicate which user should be used to authorize the request, and there are low-level credentials such as AUTH_NULL, AUTH_UNIX, AUTH_GSS which describe the credential to be sent over the wires. This patch replaces all the generic credentials by 'struct cred' pointers - the credential structure used throughout Linux. For machine credentials, there is a special 'struct cred *' pointer which is statically allocated and recognized where needed as having a special meaning. A look-up of a low-level cred will map this to a machine credential. Signed-off-by: NeilBrown Acked-by: J. Bruce Fields Signed-off-by: Anna Schumaker
