When the changes were done to the protocol last release, some endian
bugs crept in. This patch fixes those endian problems and has been
verified to run on 32/64 bit and x86/ppc architectures.This version of the patch incorporates the correct annotations
for endian variables.Signed-off-by: Eric Van Hensbergen

If INET=y and INFINIBAND=y, but IPV6=m then INFINIBAND_ADDR_TRANS is set
to n and the RDMA CM functions rdma_connect() et al are not built.
However, the current config dependencies allow NET_9P_RDMA to be selected
in this, which leads to a build failure. Fix this by adding a dependency
on INFINIBAND_ADDR_TRANS to disallow NET_9P_RDMA in this case.Reported-by: Randy Dunlap

Wrap access to task credentials so that they can be separated more easily from
the task_struct during the introduction of COW creds.Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id().
Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more
sense to use RCU directly rather than a convenient wrapper; these will be

If a T or R fcall cannot be allocated, the function returns an error
but neglects to free the wait queue that was successfully allocated.If it comes through again a second time this wq will be overwritten
with a new allocation and the old allocation will be leaked.Also, if the client is subsequently closed, the close path will
attempt to clean up these allocations, so set the req fields to
NULL to avoid duplicate free.Signed-off-by: Tom Tucker

One of the current debug options allows users to get a verbose dump of fcalls.
This isn't really necessary as correctly parsed protocol frames can be printed
as part of the code in the client functions. The consolidated printfcalls
structure would require new entries to be added for every extension. This
patch removes the debug print methods and their use.Signed-off-by: Eric Van Hensbergen
-
This adds a new protocol processing support code based on Anthony Liguori's
9p library code. This code performs protocol marshalling/unmarshalling using
printf like strings to represent protocol elements. It is my intent to use
them to replace the current functions in conv.c as well as the
p9_create_* functions.This should make the client implementation much more clear, and also make it
much easier to add new protocol extensions by limiting the number of places
in which changes need to be made.Signed-off-by: Eric Van Hensbergen

Alsmot all 9P client wire functions have their own (set of) functions.

Currently reading a directory is implemented in the client code.
This function is not actually a wire operation, but a meta operation
which calls read operations and processes the results.This patch moves this functionality to the fs layer and calls component
wire operations instead of constructing their packets. This provides a
cleaner separation and will help when we reorganize the client functions
and protocol processing methods.Signed-off-by: Eric Van Hensbergen
-
There are a couple of methods in the client code which aren't actually
wire operations. To keep things organized cleaner, these operations are
being moved to the fs layer.This patch moves the readn meta-function (which executes multiple wire
reads until a buffer is full) to the fs layer.Signed-off-by: Eric Van Hensbergen
-
Currently there are two separate versions of read and write. One for
dealing with user buffers and the other for dealing with kernel buffers.
There is a tremendous amount of code duplication in the otherwise
identical versions of these functions. This patch adds an additional
user buffer parameter to read and write and conditionalizes handling of
the buffer on whether the kernel buffer or the user buffer is populated.Signed-off-by: Eric Van Hensbergen

Post p9_fd_poll() error path which checks m->poll_waddr[i] for PTR_ERR
value has the following problems.* It's completely unused. Error value is set iff NULL @wait_address
has been specified to p9_pollwait() which is guaranteed not to
happen.* It dereferences @m after deallocating it (introduced by 571ffeaf and
spotted by Raja R Harinath.* It returned the wrong value on error. It should return
poll_waddr[i] but it returnes poll_waddr (introduced by 571ffeaf).* p9_mux_poll_stop() doesn't handle PTR_ERR value. It will try to
operate on the PTR_ERR value as if it's a normal pointer and cause
oops.As the error path is bogus in the first place, there's no reason to
hold onto it. Kill it.Signed-off-by: Tejun Heo
