2007-07-19SUNRPC: move bkl locking and xdr proc invocation into a common helperJ. Bruce Fields1-11/+2
Since every invocation of xdr encode or decode functions takes the BKL now, there's a lot of redundant lock_kernel/unlock_kernel pairs that we can pull out into a common function. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2007-07-17mm: clean up and kernelify shrinker registrationRusty Russell1-5/+6
I can never remember what the function to register to receive VM pressure is called. I have to trace down from __alloc_pages() to find it. It's called "set_shrinker()", and it needs Your Help. 1) Don't hide struct shrinker. It contains no magic. 2) Don't allocate "struct shrinker". It's not helpful. 3) Call them "register_shrinker" and "unregister_shrinker". 4) Call the function "shrink" not "shrinker". 5) Reduce the 17 lines of waffly comments to 13, but document it properly.

2007-07-10sunrpc: drop BKL around wrap and unwrapJ. Bruce Fields1-2/+11
We don't need the BKL when wrapping and unwrapping; and experiments by Avishay Traeger have found that permitting multiple encryption and decryption operations to proceed in parallel can provide significant performance improvements.

2007-07-10SUNRPC: Remove the tk_auth macro...Trond Myklebust1-12/+13
We should almost always be deferencing the rpc_auth struct by means of the credential's cr_auth field instead of the rpc_clnt->cl_auth anyway. Fix up that historical mistake, and remove the macro that propagated it. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2007-07-10SUNRPC: Fix races in rpcauth_createTrond Myklebust1-11/+24

2007-07-10SUNRPC: Fix a memory leak in the auth credcache codeTrond Myklebust1-2/+16
The leak only affects the RPCSEC_GSS caches, since they are the only ones that are dynamically allocated... Rename the existing rpcauth_free_credcache() to rpcauth_clear_credcache() in order to better describe its role, then add a new function rpcauth_destroy_credcache() that actually frees the cache in addition to clearing it out. Also move the call to destroy the credcache in gss_destroy() to come before the rpc upcall pipe is unlinked. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2007-02-03SUNRPC: fix print format for tk_pidChuck Lever1-12/+13
The tk_pid field is an unsigned short. The proper print format specifier for that type is %5u, not %4d. Also clean up some miscellaneous print formatting nits. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2006-03-20SUNRPC: Auto-load RPC authentication kernel modulesOlaf Kirch1-2/+14
This patch adds a request_module call to rpcauth_create which will try to auto-load the kernel module for the requested authentication flavor. For kernels with modular sunrpc, this reduces the admin overhead for the user. Signed-off-by: Olaf Kirch <okir@suse.de> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2006-02-01SUNRPC: Move upcall out of auth->au_ops->crcreate()Trond Myklebust1-0/+8
This fixes a bug whereby if two processes try to look up the same auth_gss credential, they may end up creating two creds, and triggering two upcalls because the upcall is performed before the credential is added to the credcache. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2006-02-01SUNRPC: Fix a lock recursion in the auth_gss downcallTrond Myklebust1-7/+10
When we look up a new cred in the auth_gss downcall so that we can stuff the credcache, we do not want that lookup to queue up an upcall in order to initialise it. To do an upcall here not only redundant, but since we are already holding the inode->i_mutex, it will trigger a lock recursion. This patch allows rpcauth cache searches to indicate that they can cope with uninitialised credentials. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2005-06-22[PATCH] RPC: [PATCH] improve rpcauthauth_create error returnsJ. Bruce Fields1-3/+3
Currently we return -ENOMEM for every single failure to create a new auth. This is actually accurate for auth_null and auth_unix, but for auth_gss it's a bit confusing. Allow rpcauth_create (and the ->create methods) to return errors. With this patch, the user may sometimes see an EINVAL instead. Whee. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+395
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!
