2018-12-19net: switch secpath to use skb extension infrastructureFlorian Westphal
Remove skb->sp and allocate secpath storage via extension infrastructure. This also reduces sk_buff by 8 bytes on x86_64. Total size of allyesconfig kernel is reduced slightly, as there is less inlined code (one conditional atomic op instead of two on skb_clone).

2018-12-19sk_buff: add skb extension infrastructureFlorian Westphal
This adds an optional extension infrastructure, with ispec (xfrm) and bridge netfilter as first users. objdiff shows no changes if kernel is built without xfrm and br_netfilter support. The third (planned future) user is Multipath TCP which is still out-of-tree. MPTCP needs to map logical mptcp sequence numbers to the tcp sequence numbers used by individual subflows. This DSS mapping is read/written from tcp option space on receive and written to tcp option space on transmitted tcp packets that are part of and MPTCP connection. Extending skb_shared_info or adding a private data field to skb fclones doesn't work for incoming skb, so a different DSS propagation method would be required for the receive side. mptcp has same requirements as secpath/bridge netfilter: 1. extension memory is released when the sk_buff is free'd. 2. data is shared after cloning an skb (clone inherits extension) 3. adding extension to an skb will COW the extension buffer if needed. The "MPTCP upstreaming" effort adds SKB_EXT_MPTCP extension to store the mapping for tx and rx processing. Two new members are added to sk_buff: 1. 'active_extensions' byte (filling a hole), telling which extensions are available for this skb. This has two purposes. a) avoids the need to initialize the pointer. b) allows to "delete" an extension by clearing its bit value in ->active_extensions. While it would be possible to store the active_extensions byte in the extension struct instead of sk_buff, there is one problem with this: When an extension has to be disabled, we can always clear the bit in skb->active_extensions. But in case it would be stored in the extension buffer itself, we might have to COW it first, if we are dealing with a cloned skb. On kmalloc failure we would be unable to turn an extension off. 2. extension pointer, located at the end of the sk_buff. If the active_extensions byte is 0, the pointer is undefined, it is not initialized on skb allocation. This adds extra code to skb clone and free paths (to deal with refcount/free of extension area) but this replaces similar code that manages skb->nf_bridge and skb->sp structs in the followup patches of the series. It is possible to add support for extensions that are not preseved on clones/copies. To do this, it would be needed to define a bitmask of all extensions that need copy/cow semantics, and change __skb_ext_copy() to check ->active_extensions & SKB_EXT_PRESERVE_ON_CLONE, then just set ->active_extensions to 0 on the new clone. This isn't done here because all extensions that get added here need the copy/cow semantics. v2: Allocate entire extension space using kmem_cache. Upside is that this allows better tracking of used memory, downside is that we will allocate more space than strictly needed in most cases (its unlikely that all extensions are active/needed at same time for same skb). The allocated memory (except the small extension header) is not cleared, so no additonal overhead aside from memory usage. Avoid atomic_dec_and_test operation on skb_ext_put() by using similar trick as kfree_skbmem() does with fclone_ref: If recount is 1, there is no concurrent user and we can free right away.

2018-12-19ext4: force inode writes when nfsd calls commit_metadata()Theodore Ts'o
Some time back, nfsd switched from calling vfs_fsync() to using a new commit_metadata() hook in export_operations(). If the file system did not provide a commit_metadata() hook, it fell back to using sync_inode_metadata(). Unfortunately doesn't work on all file systems. In particular, it doesn't work on ext4 due to how the inode gets journalled --- the VFS writeback code will not always call ext4_write_inode(). So we need to provide our own ext4_nfs_commit_metdata() method which calls ext4_write_inode() directly. Google-Bug-Id: 121195940 Signed-off-by: Theodore Ts'o <tytso@mit.edu> Cc: stable@kernel.org

2018-12-19NFS/NFSD/SUNRPC: replace generic creds with 'struct cred'.NeilBrown
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.

2018-12-19NFS: change access cache to use 'struct cred'.NeilBrown
Rather than keying the access cache with 'struct rpc_cred', use 'struct cred'. Then use cred_fscmp() to compare credentials rather than comparing the raw pointer. A benefit of this approach is that in the common case we avoid the rpc_lookup_cred_nonblock() call which can be slow when the cred cache is large. This also keeps many fewer items pinned in the rpc cred cache, so the cred cache is less likely to get large.

2018-12-19NFS: move credential expiry tracking out of SUNRPC into NFS.NeilBrown
NFS needs to know when a credential is about to expire so that it can modify write-back behaviour to finish the write inside the expiry time. It currently uses functions in SUNRPC code which make use of a fairly complex callback scheme and flags in the generic credientials. As I am working to discard the generic credentials, this has to change. This patch moves the logic into NFS, in part by finding and caching the low-level credential in the open_context. We then make direct cred-api calls on that. This makes the code much simpler and removes a dependency on generic rpc credentials.

2018-12-19SUNRPC: add side channel to use non-generic cred for rpc call.NeilBrown
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.

2018-12-19SUNRPC: introduce RPC_TASK_NULLCREDS to request auth_noneNeilBrown
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.

2018-12-19NFS/SUNRPC: don't lookup machine credential until rpcauth_bindcred().NeilBrown
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.

2018-12-19NFSv4: add cl_root_cred for use when machine cred is not available.NeilBrown
NFSv4 state management tries a root credential when no machine credential is available, as can happen with kerberos. It does this by replacing the cl_machine_cred with a root credential. This means that any user of the machine credential needs to take a lock while getting a reference to the machine credential, which is a little cumbersome. So introduce an explicit cl_root_cred, and never free either credential until client shutdown. This means that no locking is needed to reference these credentials. Future patches will make use of this. This is only a temporary addition. both cl_machine_cred and cl_root_cred will disappear later in the series.

2018-12-19SUNRPC: remove machine_cred field from struct auth_credNeilBrown
The cred is a machine_cred iff ->principal is set, so there is no need for the extra flag. There is one case which deserves some explanation. nfs4_root_machine_cred() calls rpc_lookup_machine_cred() with a NULL principal name which results in not getting a machine credential, but getting a root credential instead. This appears to be what is expected of the caller, and is clearly the result provided by both auth_unix and auth_gss which already ignore the flag.

2018-12-19SUNRPC: add 'struct cred *' to auth_cred and rpc_credNeilBrown
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.

For HDaudio and Skylake drivers, add module parameter "pci_binding" When pci_binding == 0 (AUTO), the PCI class/subclass info is used to select drivers based on the presence of the DSP. pci_binding == 1 (LEGACY) forces the use of the HDAudio legacy driver, even if the DSP is present. pci_binding == 2 (ASOC) forces the use of the ASOC driver. The information on the DSP presence is bypassed. The value for the module parameter needs to be identical for both drivers. This parameter is intended as a back-up solution if the automatic detection fails or when the DSP usage fails. Such cases should be reported on the alsa-devel mailing list for analysis.
