Update interrupt handling code to handle mem-free mode. While we're at it, improve the Tavor interrupt handling to avoid an extra MMIO read of the event cause register. Signed-off-by:

Add code to initialize EQ context properly in both Tavor and mem-free mode. Signed-off-by:

Roland Dreier authored
Add support for mem-free mode to memory region code. This mostly amounts to properly munging between keys and indices. Signed-off-by:

Roland Dreier authored
Add support for mapping more memory into HCA's context to cover context tables when new objects are allocated. Pass the object size into mthca_alloc_icm_table(), reference count the ICM chunks, and add new mthca_table_get() and mthca_table_put() functions to handle mapping memory when allocating or destroying objects.

Add support for allocating user access regions (UARs). Use this to allocate a region for kernel at driver init instead using hard-coded MTHCA_KAR_PAGE index. Signed-off-by:

Move the request/ioremap of regions related to event handling into mthca_eq.c. Map the correct regions depending on whether we're in Tavor or native mem-free mode. Signed-off-by:

Remove support for unsignaled receive requests. This is a non-standard extension to the IB spec that is not used by any known applications or protocols, and is not supported by newer hardware. Signed-off-by:

Simplify some of the code for CQ handling slightly. Signed-off-by:
-
Michael S. Tsirkin authored
Locking during the poll cq operation can be reduced by locking the cq while qp is being removed from the qp array. This also avoids an extra atomic operation for reference counting. Signed-off-by:
-
Michael S. Tsirkin authored
Avoid taking the CQ table lock in the fast path path by using synchronize_irq() after removing a CQ from the table to make sure that no completion events are still in progress. This gets a nice speedup (about 4%) in IP over IB on my hardware. Signed-off-by:

Clean up CQ code so that we only calculate the address of a CQ entry once when using it. Signed-off-by:

Fix up locking for IPoIB path table. Make sure that destruction of address handles, neighbour info and path structs is locked properly to avoid races and deadlocks. (Problem originally diagnosed by Shirley Ma) Signed-off-by:
-
Shirley Ma authored
ipoib_put_ah() may call ipoib_free_ah(), which might take the device's lock. Therefore we need to make sure we don't call ipoib_put_ah() when holding the lock already. Signed-off-by:

IPoIB small fixes: Initialize path->ah to NULL, and fix dereference after free of neigh in error path of neigh_add_path(). Signed-off-by:

Roland Dreier authored
Make IPoIB data_debug_level module parameter static to the single file where it is used. Also Rename IPoIB module parameter variable from "debug_level" to "ipoib_debug_level". This avoids possible name clashes if IPoIB is built into the kernel. We use module_param_named so that the user-visible parameter names remain the same. Signed-off-by:

Fix memory leak when posting a receive buffer (pointed out by Shirley Ma). Signed-off-by:

Roland Dreier authored
MTHCA_RESET_VALUE must always be swapped, since the HCA expects to see it in big-endian order and we write it with writel. This means on little-endian systems we have to swap it to big-endian order before writing, and on big-endian systems we need to swap it to make up for the additional swap that writel will do. This fixes resetting the HCA on big-endian machines. Signed-off-by:

This patch should fix a problem that has been experienced on at-least one busy NFS server, but it has not had lots of testing yet. If -mm could provide that ..... The rpc auth cache currently differentiates between a reference due to being in a hash chain (signalled by CACHE_HASHED flag) and any other reference (counted in refcnt). This is an artificial difference due to an historical accident, and it makes cache_put unsafe. This patch removes the distinction so now existance in a hash chain is counted just like any other reference. Thus a race window in cache_put is closed. Signed-off-by:

The pg_authenticate (now pg_authenticate_obsolete) callback was only being used by the nfs4 client callback code to circumvent the svcauth_unix code's insistence on checking all requests against the export table. With that problem solved, we no longer need it. Signed-off-by:

On lockd callbacks, we're a client, and the source address is that of a server, so we shouldn't be trying to match the source address of the callback request against our export table. Signed-off-by:
-
Neil Brown authored
Use new pg_authenticate method to simplify nfs4 callback authentication. This also has the effect of changing the error return from rejectedcred to badcred. I believe the change is correct. Signed-off-by:

Neil Brown authored
svcauth_null_accept() and svcauth_unix_accept() are currently hard-wired to check the source ip address on an incoming request against the export table, which make sense for nfsd but not necessarily for other rpc-based services. So instead we have the accept() method call a program-specific pg_authenticate() method. We also move the call to this method into svc_process instead of calling it from the flavor-specific accept() routines. Signed-off-by:
-
Neil Brown authored
Later patches remove pg_authenticate and use the name for a different purpose; so rename it to pg_authenticate_obsolete for now. Signed-off-by:
-
Neil Brown authored
Add a set_client method to the server rpc auth_ops struct, used to set the client (for the purposes of nfsd export authorization) using flavor-specific information. Signed-off-by:

find_exported_dentry() declares char nbuf[NAME_MAX+1]; in 2 separate places, and gcc allocates space on the stack for both of them. Having just one of them will suffice, if we can put put with its scope. Reduces function stack usage on x86-32 from 0x230 to 0x130. Signed-off-by:

This patch makes "find" work when traversing nohide exports on NFSv3. The READDIRPLUS reply needs to not return a file handle for the ".." entry when the directory is a server side mountpoint, which would be the directory itself, otherwise the client remembers the wrong file handle and gets confused.
