* NFS: Update MNT and MNT3 reply decoding functionsChuck Lever2009-06-17
| | | | | | | | | | | | | Solder xdr_stream-based XDR decoding functions into the in-kernel mountd client that are more careful about checking data types and watching for buffer overflows. The new MNT3 decoder includes support for auth-flavor list decoding. The "_sz" macro for MNT3 replies was missing the size of the file handle. I've added this back, and included the size of the auth flavor array. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: Clean up MNT program definitionsChuck Lever2009-06-17
| | | | | | | | | | Clean up: Relocate MNT program procedure number definitions to the only file that uses them. Relocate the version number definitions, which are shared, to nfs.h. Remove duplicate program number definitions. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* nfs: fix build error in nfsroot with initconstSam Ravnborg2009-05-26
| | | | | | | | | | | | | | | | | | | | | | | | | | fix build error with latest kbuild adjustments to initconst. The commit a447c0932445f92ce6f4c1bd020f62c5097a7842 ("vfs: Use const for kernel parser table") changed: static match_table_t __initdata tokens = { to static match_table_t __initconst tokens = { But the missing const causes popwerpc to fail with latest updates to __initconst like this: fs/nfs/nfsroot.c:400: error: __setup_str_nfs_root_setup causes a section type conflict fs/nfs/nfsroot.c:400: error: __setup_str_nfs_root_setup causes a section type conflict The bug is only present with kbuild-next. Following patch has been build tested.

* vfs: Use const for kernel parser tableSteven Whitehouse2008-10-13
| | | | | | | | | | | | | | This is a much better version of a previous patch to make the parser tables constant. Rather than changing the typedef, we put the "const" in all the various places where its required, allowing the __initconst exception for nfsroot which was the cause of the previous trouble. This was posted for review some time ago and I believe its been in -mm since then.

* NFS: Remake nfsroot_mount as a permanent part of NFS clientChuck Lever2007-07-10
| | | | | | | | | | | | In preparation for supporting NFSv2 and NFSv3 mount option handling in the kernel NFS client, convert mount_clnt.c to be a permanent part of the NFS client, instead of built only when CONFIG_ROOT_NFS is enabled. In addition, we also replace the "struct sockaddr_in *" argument with something more generic, to help support IPv6 at some later point.

* [PATCH] nfsroot: do not silently stop parsing on an unknown optionJorn Dreyer2006-01-08
| | | | | | | | | | | | It would be helpful if the kernel did not silently stop parsing nfs options, but instead warned about any he does not recognize.

* NFS: support large reads and writes on the wireChuck Lever2006-01-06
| | | | | | | | | | | | | | | | | Most NFS server implementations allow up to 64KB reads and writes on the wire. The Solaris NFS server allows up to a megabyte, for instance. Now the Linux NFS client supports transfer sizes up to 1MB, too. This will help reduce protocol and context switch overhead on read/write intensive NFS workloads, and support larger atomic read and write operations on servers that support them. Test-plan: Connectathon and iozone on mount point with wsize=rsize>32768 over TCP. Tests with NFS over UDP to verify the maximum RPC payload size cap.

* [PATCH] NFS: Add support for NFSv3 ACLsAndreas Gruenbacher2005-06-22
| | | | | | | | | | | | | This adds acl support fo nfs clients via the NFSACL protocol extension, by implementing the getxattr, listxattr, setxattr, and removexattr iops for the system.posix_acl_access and system.posix_acl_default attributes. This patch implements a dumb version that uses no caching (and thus adds some overhead). (Another patch in this patchset adds caching as well.)

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
