* stripe: fix use-after-freeJeff Darcy2015-06-021-4/+10
| | | | | | | | | | | | | | | | Pretty much a classic case. STRIPE_STACK_UNWIND frees the "local" structure. In the "virtual xattr" path, used for lock recovery among other things, we were calling STRIPE_STACK_UNWIND and then continuing to clean up "our" parts of the just-freed structure. Oops.

* stripe: set ENOENT when a READ hits EOFNiels de Vos2015-05-071-0/+5
| | | | | | | | | | | | | | | | | | | | | | | The NFS-server sets EOF only in the READ reply when op_errno is set to ENOENT. Xlators are expected to set op_errno to ENOENT when EOF is reached, op_ret will contain the number of bytes returned by the READ. When an NFS-client (like VMware ESXi) do a READ that exceeds the size of the file, errno should be set to EOF and the return value contains the number of bytes that are read (from the requested offset, until the end of the file). Not setting EOF on a correct short READ, can result in errors on the NFS-client. This is not an issue with the Linux NFS-client (or VFS). Linux is smart enough to not try to read more bytes than the file contains.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-041-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

* NFS: stripe-xlator should pass EOF at end of READDIRNiels de Vos2014-08-191-11/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | NFS READDIR replies are made of a header, a sequence of entries, and a EOF flag. When GlusterFS's NFS server is used along with stripe xlator, it fails to set the EOF flag, which violates NFS RFC and confuses some clients. The bug is caused because nfs xlator sets EOF if it gets op_errno set to ENOENT. That value is produced in storage xlator and propagated through server, client, and other xlators until stripe xlator handles it. stripe only passed op_errno if op_ret < 0, which is not the case here. This change set adds a special case for that situation to fix the problem.

| | | | | | | | | | | | | | | | | | Write operations on directories with quota enabled used to fail with EINVAL on stripe volumes. This was due to assert failure in stripe_lookup(), meant to ensure loc->path is not NULL. However, in nameless lookup (in this particular case triggered by quotad, which has stripe xlator in its graph), loc->path can be legitimately NULL. The fix involves removing this check in stripe_lookup().

Zerofill writes zeroes to a file in the specified range. This fop will be useful when a whole file needs to be initialized with zero (could be useful for zero filled VM disk image provisioning or during scrubbing of VM disk images). Client/application can issue this FOP for zeroing out. Gluster server will zero out required range of bytes ie server offloaded zeroing. In the absence of this fop, client/application has to repetitively issue write (zero) fop to the server, which is very inefficient method because of the overheads involved in RPC calls and acknowledgements. WRITESAME is a SCSI T10 command that takes a block of data as input and writes the same data to other blocks and this write is handled completely within the storage and hence is known as offload . Linux ,now has support for SCSI WRITESAME command which is exposed to the user in the form of BLKZEROOUT ioctl. BD Xlator can exploit BLKZEROOUT ioctl to implement this fop. Thus zeroing out operations can be completely offloaded to the storage device , making it highly efficient. The fop takes two arguments offset and size. It zeroes out 'size' number of bytes in an opened file starting from 'offset' position. This patch adds zerofill support to the following areas: - libglusterfs - io-stats - performance/md-cache,open-behind - quota - cluster/afr,dht,stripe - rpc/xdr - protocol/client,server - io-threads - marker - storage/posix - libgfapi Client applications can exloit this fop by using glfs_zerofill introduced in libgfapi.FUSE support to this fop has not been added as there is no system call for this fop. Changes from previous version 3: * Removed redundant memory failure log messages Changes from previous version 2: * Rebased and fixed build error Changes from previous version 1: * Rebased for latest master TODO : * Add zerofill support to trace xlator * Expose zerofill capability as part of gluster volume info Here is a performance comparison of server offloaded zeofill vs zeroing out using repeated writes.

| | | | | | | | | | | | | | | | | | | | | | | cluster/stripe write callback handling is broken in the event of server side errors and short writes due to crudely summing up the return values from each node. This can produce incorrect results or cause an application to rewrite the wrong portions of a buffer in an attempt to handle this condition. Modify cluster/stripe writev handling to record the requested size of each write and use this data to return the number of consecutive bytes written from the original request. This allows an application to retry a write at the point of error (and potentially consume said error).

| | | | | | | | | | | | | | | | | | | | | | | | A crash occurs when attempting to link a named pipe on a striped, replicated volume. The cause for this crash is attempting to deref a NULL inode pointer in stripe_link_cbk(). The RCA for this bug uncovered a couple of problems: - AFR ignores the inode pointer it receives on failure (returning NULL). - stripe assumes the inode pointer is valid on failure. Either one of these changes addresses the crash, but this patch includes both changes. AFR is modified to pass along the inode pointer it receives (which could still be NULL). stripe is modified to not assume the inode pointer is valid on fop failure.

* cluster/stripe: implement the coalesce stripe file formatBrian Foster2012-06-073-78/+407
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The coalesce file format for cluster/stripe condenses the striped files to a contiguous layout. The elimination of holes in striped files eliminates space wasted via local filesystem preallocation heuristics and significantly improves read performance. Coalesce mode is implemented with a new 'coalesce' xlator option, which is user-configurable and disabled by default. The format of newly created files is marked with a new 'stripe-coalesce' xattr. Cluster/stripe handles/preserves the format of files regardless of the current mode of operation (i.e., a volume can simultaneously consist of coalesced and non-coalesced files). Files without the stripe-coalesce attribute are assumed to have the traditional format to provide backward compatibility. extras/stripe-merge: support traditional and coalesce stripe formats Update the stripe-merge recovery tool to handle the traditional and coalesced file formats. The format of the file is detected automatically (and verified) via the stripe-coalesce attributes.
