features/bitrot: add check for corrupted object in f{stat}

2016-01-10T12:43:28+00:00

Check for corrupted objects is done bt bitrot stub component
for data operations and such fops are denied processing by
returning EIO. These checks were not done for operations such
as get/set extended attribute, stat and the likes - IOW, stub
only blocked pure data operations.

However, its necessary to have these checks for certain other
fops, most importantly stat (and fstat). This is due to the
fact that clients could possibly get stale stat information
(such as size, {a,c,m}time) resulting in incorrect operation
of the application that rely on these fields. Note that, the
data that replication would take care of fetching good (and
correct) data, but the staleness of stat information could
lead to data inconsistencies (e.g., rebalance, tier).

features/bitrot: fix fd leak in truncate (stub)

2015-06-16T09:22:21+00:00

The need to perform object versioning in the truncate() code path
required an fd to reuse existing versioning infrastructure that's
used by fd based operations (such as writev(), ftruncate(), etc..).

This tempted the use of anonymous fd which was never ever unref()'d
after use resulting in fd and/or memory leak depending on the code
path taken. Versioning resulted in a dangling file descriptor left
open in the filesystem effecting the signing process of a given
object (no release() would be trigerred, hence no signing would be
performed). On the other hand, cases where the object need not be
versioned, the anonymous fd in still ref()'d resulting in memory
leak (NOTE: there's no "dangling" file descriptor in this case).

features/bitrot: tuanble object signing waiting time value for bitrot

2015-06-15T12:23:46+00:00

 Currently bitrot using 120 second waiting time for object to be signed
 after all fop's released. This signing waiting time value should be tunable.

 Command for changing the signing waiting time will be
 #gluster volume bitrot  signing-time

This is to prevent access to uninitialized variable in reconfigure()
that's currently getting inititlized on CHILD_UP.

    NOTE: This is a temporary fix and would not be needed when BZ

bitrot: Volfile generation should not proceed if node doesn't have any brick.

2015-05-10T05:25:15+00:00

glusterd crashes when bitrot is enabled on a distributed volume from a node
which doesn't host a brick.

While generating volfile glusterd should check number of brick on that node. If
node doesn't have any brick then graph generation for bitrot and scrubber should
not proceed further.
