gfapi: async fops should unref in callbacks

2016-11-10T08:25:11+00:00

If fd is unref'd at the end of async call then the unref in cbks would
lead to double unref and possible crash. Removing duplicate unrefs.

Added unref only in failure cases.

A simple test case has been added to test async write case. Need to
extend the same for other async APIs too.

Details:
All glfd based calls in libgfapi, except for glfs_open and glfs_close,
behave in the same way. At the start of the operation, they take a ref
on glfd and fd. At the end of the operation, they unref it. Async calls
are a little different as they unref in the cbk function. A successfull
open call does not unref either the glfd or fd, thereby functioning as a
reference for a OPEN file object. glfs_close makes a syncop_flush call
sandwiched between a fd ref and unref(this can be removed, more on this
below), followed by a call to glfs_mark_glfd_for_deletion which unrefs
glfd and also calls glfs_fd_destroy as a release function thereby doing
a unref on fd too.

Functionally, there is no problem with how everything works when as
described above. However, it is a little non-intuitive that we need to
perform a fd_unref as a consequence of a implicit fd_ref that happens
within glfs_resolve_fd. As we perform a GF_REF_GET(glfd) at the start of
every operation, it would be worthwhile to remove the fd_ref that
glfs_resovle_fd takes and do away with explicit fd_unref()s at the end
of every operation. This is the same reason why we don't need the fd_ref
in glfs_close. This is however not in the scope of this patch.

compound fops: Fix file corruption issue

2016-10-25T04:14:54+00:00

        Backport of: http://review.gluster.org/#/c/15654/

1. Address of a local variable @args is copied into state->req
in server3_3_compound (). But even after the function has gone out of
scope, in server_compound_resume () this pointer is accessed and
dereferenced. This patch fixes that.

2. Compound fops, by virtue of NOT having a vector sizer (like the one
writev has), ends up having both the header and the data (in case one of
its member fops is WRITEV) in the same hdr_iobuf. This buffer was not
being preserved through the lifetime of the compound fop, causing it to
be overwritten by a parallel write fop, even when the writev associated
with the currently executing compound fop is yet to hit the desk, thereby
corrupting the file's data. This is fixed by associating the hdr_iobuf with
the iobref so its memory remains valid through the lifetime of the fop.

3. Also fixed a use-after-free bug in protocol/client in compound fops cbk,
missed by Linux but caught by NetBSD.

Finally, big thanks to Pranith Kumar K and Raghavendra Gowdappa for their
help in debugging this file corruption issue.

cluster/ec: set/unset dirty flag for data/metadata update

2016-10-13T20:04:11+00:00

Currently, for all the update operations, metadata or data,
we set the dirty flag at the end of the operation only if
a brick is down. This leads to delay in healing and in some
cases not at all.
In this patch we set (+1) the dirty flag
at the start of the metadata or data update operations and
after successfull completion of the fop, we unset (-1) it again.

cluster/ec: Implement heal info with lock

2016-10-13T14:35:46+00:00

Problem: Currently heal info command prints all
the files/directories if the index for the
file/directory is present in .glusterfs/indices folder.
After implementing patch http://review.gluster.org/#/c/13733/
indices of the file which is going through update fop
will also be present in .glusterfs/indices even
if the fop is successful on all the brick. At this time
if heal info command is being used, it will also display this
file which is actually healthy and does not require any heal.

Solution: Take lock on a file corresponding to the indices
and inspect xattrs to decide if the file needs heal or not.

gfapi: redesign the public interface for upcall consumers

2016-10-11T12:18:56+00:00

The glfs_callback_arg and glfs_callback_inode_arg were allocated by
gfapi, and expected to be free()'d by the application. However it is not
reasonable to expect that applications use the same memory allocator to
as the compiled libgfapi.so. For instance, it is possible that gfapi
uses glibc malloc/free, and an application like NFS-Ganesha the versions
from jemalloc. Mismatching of the malloc() and free() functions causes
segmentation faults at best.

In order to prevent problems like this in the future, the API for
applications that consume upcalls has been remodeled. Any of the
structures that gfapi allocates, should be free'd with glfs_free(). The
members of the structures can not be accessed directly anymore, each
has its own function to access now.

Correcting the naming of the functions, structures and constants is a
continuation of commit 2775dc64101ed37c8d9809bf9852dbf0746ee2b6. These
new improvements not only have correct prefixes for the functions and
structures, the naming also reflects more to the upcall framework and
does not use "callback" anymore.

cluster/ec: Add support for hardware acceleration

2016-09-10T02:19:13+00:00

This patch implements functionalities for fast encoding/decoding
using hardware support. Currently optimized x86_64, SSE and AVX is
added.

Additionally this patch implements a caching mecanism for inverse
matrices to reduce computation time, as well as a new method for
computing the inverse that takes quadratic time instead of cubic.

Finally some unnecessary memory copies have been eliminated to
further increase performance.
