Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

nfsd: use get_acl and ->set_acl Remove the boilerplate code to marshall and unmarhall ACL objects into xattrs and operate on the posix_acl objects directly.

NFSD: add posix ACLs to struct nfsd_attrs pacl and dpacl pointers are added to struct nfsd_attrs, which requires that we have an nfsd_attrs_free() function to free them. Those nfsv4 functions that can set ACLs now set up these pointers based on the passed in NFSv4 ACL. nfsd_setattr() sets the acls as appropriate. Errors are handled as with security labels.

nfsd4: remove nfs4_acl_new This is a not-that-useful kmalloc wrapper. And I'd like one of the callers to actually use something other than kmalloc. Signed-off-by: J. Bruce Fields <bfields@redhat.com>

int nfs4_acl_get_whotype(char *, u32);
nfsd4: use xdr_reserve_space in attribute encoding This is a cosmetic change for now; no change in behavior. Note we're just depending on xdr_reserve_space to do the bounds checking for us, we're not really depending on its adjustment of iovec or xdr_buf lengths yet, as those are fixed up by as necessary after the fact by read-link operations and by nfs4svc_encode_compoundres. However we do have to update xdr->iov on read-like operations to prevent xdr_reserve_space from messing with the already-fixed-up length of the the head. When the attribute encoding fails partway through we have to undo the length adjustments made so far. We do it manually for now, but later patches will add an xdr_truncate_encode() helper to handle cases like this. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
