fs/9p: Add OS dependent open flags in 9p protocol

2011-10-03T18:40:21Z

commit f88657ce3f9713a0c62101dffb0e972a979e77b9 upstream. Some of the flags are OS/arch dependent we add a 9p protocol value which maps to asm-generic/fcntl.h values in Linux Based on the original patch from Venkateswararao Jujjuri [extra comments from author as to why this needs to go to stable: Earlier for different operation such as open we used the values of open flag as defined by the OS. But some of these flags such as O_DIRECT are arch dependent. So if we have the 9p client and server running on different architectures, we end up with client sending client architecture value of these open flag and server will try to map these values to what its architecture states. For ex: O_DIRECT on a x86 client maps to #define O_DIRECT 00040000 Where as on sparc server it will maps to #define O_DIRECT 0x100000 Hence we need to map these open flags to OS/arch independent flag values. Getting these changes to an early version of kernel ensures us that we work with different combination of client and server. We should ideally backport this patch to all possible kernel version.] Signed-off-by: Aneesh Kumar K.V Signed-off-by: Harsh Prateek Bora Signed-off-by: Greg Kroah-Hartman

9p: Small cleanup in

2011-05-25T13:46:38Z

There are two small cleanups in this patch: - p9_errstr2errno was declared twice - remove one declaration. - A uint8_t type was mixed in, change it to u8 to match with the rest of the type names and remove dependency.

9p: revert tsyncfs related changes

2011-04-15T20:26:14Z

Now that we use write_inode to flush server cache related to fid, we don't need tsyncfs either fort dotl or dotu protocols. For dotu this helps to do a more efficient server flush. Signed-off-by: Aneesh Kumar K.V Signed-off-by: Venkateswararao Jujjuri Signed-off-by: Eric Van Hensbergen

[net/9p] Small non-IO PDUs for zero-copy supporting transports.

2011-03-15T14:57:36Z

If a transport prefers payload to be sent separate from the PDU (P9_TRANS_PREF_PAYLOAD_SEP), there is no need to allocate msize PDU buffers(struct p9_fcall). This patch allocates only upto 4k buffers for this kind of transports and there won't be any change to the legacy transports. Hence, this patch on top of zero copy changes allows user to specify higher msizes through the mount option without hogging the kernel heap.

[net/9p] Preparation and helper functions for zero copy

2011-03-15T14:57:34Z

This patch prepares p9_fcall structure for zero copy. Added fields send the payload buffer information to the transport layer. In addition it adds a 'private' field for the transport layer to store mapped/pinned page information so that it can be freed/unpinned during req_done. This patch also creates trans_common.[ch] to house helper functions. It adds the following helper functions. p9_release_req_pages - Release pages after the transaction. p9_nr_pages - Return number of pages needed to accomodate the payload. payload_gup - Translates user buffer into kernel pages.
