| | | | | | | | | | | | | | | | When a lookup request comes in for (rootfh, ".."), we need to handle it in a way that returns the attributes and handle of the root dir. Not doing so crashes nfsx because the inode table is not able to find a inode for the root's parent. This inode was being referenced in nfs3_lookup_parentdir_resume when filling a loc for the lookup fop. For the record, such a lookup request is sent by vmkernel.

* performance/write-behind: explicitly enforce ordering of overlapping writes.Raghavendra G2010-05-261-128/+126
| | | | | | | | | | | | | | | | | - If there are non-contiguous offsets (offsets which do not start where previous write ended), wait for completion of previous writes to server before sending new ones. - Send flush call to server only when all writes are completed. - If a file is opened with O_APPEND, at any point of time a maximum only one write call to server should be in transit. This is to avoid reordering of writes in the presence of afr which can result in data corruption. See bug #934 for more details.

* nfs: Introduce trusted-write and trusted-sync optionsShehjar Tikoo2010-05-213-6/+183
| | | | | | | | | | | | | | | | | | | | | | | | Introduces two new options: 1. nfs3.*.trusted-write: Forces UNSTABLE writes to return STABLE to NFS clients to prevent the clients from sending a COMMIT. STABLE writes are still handled in a sync manner and so are COMMITs if they're sent at all. 2. nfs3.*.trusted-sync: Forces all WRITEs and COMMITs to return STABLE return flags to NFS clients to avoid the overhead of STABLE writes, and COMMITs that follow UNSTABLE writes. This includes the trusted-write functionality. In addition to the trusted-write, it also writes STABLE writes in an UNSTABLE manner. Both violate the NFS protocol but allow better write perf in most configurations. Use with caution. Signed-off-by: Shehjar Tikoo <shehjart@gluster.com> Signed-off-by: Anand V.
