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!

SUNRPC: Add rpcauth_list_flavors() The gss_mech_list_pseudoflavors() function provides a list of currently registered GSS pseudoflavors. This list does not include any non-GSS flavors that have been registered with the RPC client. nfs4_find_root_sec() currently adds these extra flavors by hand. Instead, nfs4_find_root_sec() should be looking at the set of flavors that have been explicitly registered via rpcauth_register(). And, other areas of code will soon need the same kind of list that contains all flavors the kernel currently knows about (see below). Rather than cloning the open-coded logic in nfs4_find_root_sec() to those new places, introduce a generic RPC function that generates a full list of registered auth flavors and pseudoflavors. A new rpc_authops method is added that lists a flavor's pseudoflavors, if it has any. I encountered an interesting module loader loop when I tried to get the RPC client to invoke gss_mech_list_pseudoflavors() by name. This patch is a pre-requisite for server trunking discovery, and a pre-requisite for fixing up the in-kernel mount client to do better automatic security flavor selection.

NFS/NFSD/SUNRPC: replace generic creds with 'struct cred'. 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 <neilb@suse.com> Acked-by: J.

NFS/SUNRPC: don't lookup machine credential until rpcauth_bindcred(). When NFS creates a machine credential, it is a "generic" credential, not tied to any auth protocol, and is really just a container for the princpal name. This doesn't get linked to a genuine credential until rpcauth_bindcred() is called. The lookup always succeeds, so various places that test if the machine credential is NULL, are pointless. As a step towards getting rid of generic credentials, this patch gets rid of generic machine credentials. The nfs_client and rpc_client just hold a pointer to a constant principal name. When a machine credential is wanted, a special static 'struct rpc_cred' pointer is used. rpcauth_bindcred() recognizes this, finds the principal from the client, and binds the correct credential.

sunrpc: Fix bit count when setting hashtable size to power-of-two Author: Frank Sorenson <sorenson@redhat.com> Date: 2016-06-27 13:55:48 -0500 sunrpc: Fix bit count when setting hashtable size to power-of-two The hashtable size is incorrectly calculated as the next higher power-of-two when being set to a power-of-two. fls() returns the bit number of the most significant set bit, with the least significant bit being numbered '1'. For a power-of-two, fls() will return a bit number which is one higher than the number of bits required, leading to a hashtable which is twice the requested size. In addition, the value of (1 << nbits) will always be at least num, so the test will never be true. Fix the hash table size calculation to correctly set hashtable size, and eliminate the unnecessary check.

SUNRPC: Introduce rpcauth_get_pseudoflavor() A SECINFO reply may contain flavors whose kernel module is not yet loaded by the client's kernel. A new RPC client API, called rpcauth_get_pseudoflavor(), is introduced to do proper checking for support of a security flavor. When this API is invoked, the RPC client now tries to load the module for each flavor first before performing the "is this supported?" check. This means if a module is available on the client, but has not been loaded yet, it will be loaded and registered automatically when the SECINFO reply is processed. The new API can take a full GSS tuple (OID, QoP, and service). Previously only the OID and service were considered. nfs_find_best_sec() is updated to verify all flavors requested in a SECINFO reply, including AUTH_NULL and AUTH_UNIX. Previously these two flavors were simply assumed to be supported without consulting the RPC client. Note that the replaced version of nfs_find_best_sec() can return RPC_AUTH_MAXFLAVOR if the server returns a recognized OID but an unsupported "service" value. nfs_find_best_sec() now returns RPC_AUTH_UNIX in this case.

RPC: Fix two potential races in put_rpccred It is possible for rpcauth_destroy_credcache() to cause the rpc credentials to be unhashed while put_rpccred is waiting for the rpc_credcache_lock on another cpu. Should this happen, then we can end up calling hlist_del_rcu(&cred->cr_hash) a second time in put_rpccred, thus causing list corruption. Should the credential actually be hashed, it is also possible for rpcauth_lookup_credcache to find and reference it before we get round to unhashing it. In this case, the call to rpcauth_unhash_cred will fail, and so we should just exit without destroying the cred.

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!

SUNRPC: Make the credential cache hashtable size configurable This patch allows the user to configure the credential cache hashtable size using a new module parameter: auth_hashtable_size When set, this parameter will be rounded up to the nearest power of two, with a maximum allowed value of 1024 elements.

hlist: drop the node parameter from iterators I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually.

SUNRPC: add 'struct cred *' to auth_cred and rpc_cred The SUNRPC credential framework was put together before Linux has 'struct cred'. Now that we have it, it makes sense to use it. This first step just includes a suitable 'struct cred *' pointer in every 'struct auth_cred' and almost every 'struct rpc_cred'. The rpc_cred used for auth_null has a NULL 'struct cred *' as nothing else really makes sense. For rpc_cred, the pointer is reference counted. For auth_cred it isn't. struct auth_cred are either allocated on the stack, in which case the thread owns a reference to the auth, or are part of 'struct generic_cred' in which case gc_base owns the reference, and "acred" shares it.

When a credential is needed, simply allocate it. When not needed, discard it. This can easily be faster than performing a lookup on a shared hash table. As the lookup can happen during write-out, use a mempool to ensure forward progress. This means that we cannot compare two credentials for equality by comparing the pointers, but we never do that anyway.

SUNRPC: add side channel to use non-generic cred for rpc call. The credential passed in rpc_message.rpc_cred is always a generic credential except in one instance. When gss_destroying_context() calls rpc_call_null(), it passes a specific credential that it needs to destroy. In this case the RPC acts *on* the credential rather than being authorized by it. This special case deserves explicit support and providing that will mean that rpc_message.rpc_cred is *always* generic, allowing some optimizations. So add "tk_op_cred" to rpc_task and "rpc_op_cred" to the setup data. Use this to pass the cred down from rpc_call_null(), and have rpcauth_bindcred() notice it and bind it in place.

NFS/NFSD/SUNRPC: replace generic creds with 'struct cred'. 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 <neilb@suse.com> Acked-by: J.

NFS/SUNRPC: don't lookup machine credential until rpcauth_bindcred(). When NFS creates a machine credential, it is a "generic" credential, not tied to any auth protocol, and is really just a container for the princpal name. This doesn't get linked to a genuine credential until rpcauth_bindcred() is called. The lookup always succeeds, so various places that test if the machine credential is NULL, are pointless. As a step towards getting rid of generic credentials, this patch gets rid of generic machine credentials. The nfs_client and rpc_client just hold a pointer to a constant principal name. When a machine credential is wanted, a special static 'struct rpc_cred' pointer is used. rpcauth_bindcred() recognizes this, finds the principal from the client, and binds the correct credential.

NFS: discard NFS_RPC_SWAPFLAGS and RPC_TASK_ROOTCREDS NFS_RPC_SWAPFLAGS is only used for READ requests. It sets RPC_TASK_SWAPPER which gives some memory-allocation priority to requests. This is not needed for swap READ - though it is for writes where it is set via a different mechanism. RPC_TASK_ROOTCREDS causes the 'machine' credential to be used. This is not needed as the root credential is saved when the swap file is opened, and this is used for all IO. So NFS_RPC_SWAPFLAGS isn't needed, and as it is the only user of RPC_TASK_ROOTCREDS, that isn't needed either. Remove both.

SUNRPC: introduce RPC_TASK_NULLCREDS to request auth_none In almost all cases the credential stored in rpc_message.rpc_cred is a "generic" credential. One of the two expections is when an AUTH_NULL credential is used such as for RPC ping requests. To improve consistency, don't pass an explicit credential in these cases, but instead pass NULL and set a task flag, similar to RPC_TASK_ROOTCREDS, which requests that NULL credentials be used by default.

SUNRPC: The transmitted message must lie in the RPCSEC window of validity If a message has been encoded using RPCSEC_GSS, the server is maintaining a window of sequence numbers that it considers valid. The client should normally be tracking that window, and needs to verify that the sequence number used by the message being transmitted still lies inside the window of validity. So far, we've been able to assume this condition would be realised automatically, since the client has been encoding the message only after taking the socket lock. Once we change that condition, we will need the explicit check. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>

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.
