sunrpc: increase UNX_MAXNODENAME from 32 to __NEW_UTS_LEN bytes

2015-08-12T18:31:04Z

The current limit of 32 bytes artificially limits the name string that we end up stuffing into NFSv4.x client ID blobs. If you have multiple hosts with long hostnames that only differ near the end, then this can cause NFSv4 client ID collisions. Linux nodenames are actually limited to __NEW_UTS_LEN bytes (64), so use that as the limit instead. Also, use XDR_QUADLEN to specify the slack length, just for clarity and in case someone in the future changes this to something not evenly divisible by 4.

sunrpc: eliminate RPC_DEBUG

2014-11-24T22:31:46Z

It's always set to whatever CONFIG_SUNRPC_DEBUG is, so just use that. Signed-off-by: Jeff Layton Signed-off-by: Trond Myklebust

SUNRPC refactor rpcauth_checkverf error returns

2013-09-03T19:25:09Z

Most of the time an error from the credops crvalidate function means the server has sent us a garbage verifier. The gss_validate function is the exception where there is an -EACCES case if the user GSS_context on the client has expired. Signed-off-by: Andy Adamson Signed-off-by: Trond Myklebust

SUNRPC: Replace clnt->cl_principal

2013-08-30T13:19:36Z

The clnt->cl_principal is being used exclusively to store the service target name for RPCSEC_GSS/krb5 callbacks. Replace it with something that is stored only in the RPCSEC_GSS-specific code. Signed-off-by: Trond Myklebust

sunrpc: Properly encode kuids and kgids in RPC_AUTH_UNIX credentials

2013-02-13T14:15:24Z

When writing kuids onto the wire first map them into the initial user namespace. When writing kgids onto the wire first map them into the initial user namespace. Cc: "J. Bruce Fields" Cc: Trond Myklebust Signed-off-by: "Eric W. Biederman"

sunrpc: Use gid_valid to test for gid != INVALID_GID

2013-02-13T14:15:20Z

In auth unix there are a couple of places INVALID_GID is used a sentinel to mark the end of uc_gids array. Use gid_valid as a type safe way to verify we have not hit the end of valid data in the array. Cc: "J. Bruce Fields" Cc: Trond Myklebust Signed-off-by: "Eric W. Biederman"

sunrpc: Convert kuids and kgids to uids and gids for printing

2013-02-13T14:15:19Z

When printing kuids and kgids for debugging purpropses convert them to ordinary integers so their values can be fed to the oridnary print functions. Cc: "J. Bruce Fields" Cc: Trond Myklebust Signed-off-by: "Eric W. Biederman"

sunrpc: Simplify auth_unix now that everything is a kgid_t

2013-02-13T14:15:18Z

In unx_create_cred directly assign gids from acred->group_info to cred->uc_gids. In unx_match directly compare uc_gids with group_info. Now that both group_info and unx_cred gids are stored as kgids this is valid and the extra layer of translation can be removed. Cc: "J. Bruce Fields" Cc: Trond Myklebust Signed-off-by: "Eric W.

sunrpc: Use uid_eq and gid_eq where appropriate

2013-02-13T14:15:17Z

When comparing uids use uid_eq instead of ==. When comparing gids use gid_eq instead of ==. And unfortunate cost of type safety. Cc: "J. Bruce Fields" Cc: Trond Myklebust Signed-off-by: "Eric W. Biederman"

sunrpc: Use kuid_t and kgid_t where appropriate

2013-02-13T14:15:16Z

Convert variables that store uids and gids to be of type kuid_t and kgid_t instead of type uid_t and gid_t. Cc: "J. Bruce Fields" Cc: Trond Myklebust Signed-off-by: "Eric W. Biederman"
