* netfs.h (netfs_report_access): Return error_t. * file-check-access.c (netfs_S_file_check_access): Deal with errors from netfs_report_access. Sat Nov 16 17:17:50 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * io-restrict-auth.c (netfs_S_io_restrict_auth): Fix several typos. * fsys-getroot.c (netfs_S_fsys_getroot): iohelp_make_iouser -> iohelp_create_iouser. New arg syntax for fshelp_fetch_root. Fri Nov 15 13:39:03 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu> * netfs.h (struct protid): Replace member `credential' with `user' of new type. All uses of old `credential' member changed to use `user' member. Change all functions that used to take `struct netcred' args to take `struct iouser' args. All callers changed. (netfs_copy_credential, netfs_dropy_credential, netfs_make_credential): Delete functions. * dir-lookup.c (netfs_S_dir_lookup): netfs_copy_credential -> iohelp_dup_iouser. * dir-mkfile.c (netfs_S_dir_mkfile): Likewise. * file-exec.c (netfs_S_file_exec): Likewise. * io-duplicate.c (netfs_S_io_duplicate): Likewise. * release-protid.c (netfs_release_protid): netfs_drop_credential -> iohelp_free_iouser. * dir-lookup.c (netfs_S_dir_lookup): Omit uses of netfs_interpret_credential; do it with new structures. * file-exec.c (netfs_S_file_exec): Likewise. * file-getcontrol.c (netfs_S_file_getcontrol): Likewise. * file-set-translator.c (netfs_S_file_set_translator): Likewise; using fshelp_isowner for permission check. * io-restrict-auth.c (netfs_S_io_restrict_auth): Likewise; guts rewritten. * dir-lookup.c (netfs_S_dir_lookup): netfs_make_credential -> iohelp_make_iouser. * fsys-getroot.c (netfs_S_fsys_getroot): Likewise. * fsys-syncfs.c (netfs_S_fsys_syncfs): Likewise. * io-reauthenticate.c (netfs_S_io_reauthenticate): Use iohelp_reauth instead of doing it by hand.
