Events: Socket creation after getaddrinfo and IPv4 and IPv6 packet capture

2020-09-14T20:01:45+00:00

Issue: Currently, the socket creation is done
prior to getaddrinfo function being invoked. This
can cause mismatch in the protocol and address
families of the created socket and the result
of the getaddrinfo api. Also, the glustereventsd
UDP server by default only captures IPv4 packets
hence IPv6 packets are not even captured.

Code Changes:
1. Modified the socket creation in such a way that
the parameters taken in are dependent upon the
result of the getaddrinfo function.
2. Created a subclass for adding address family
in glustereventsd.py for both AF_INET and AF_INET6.
3. Modified addresses in the eventsapiconf.py.in

Reasoning behind the approach:
1. If we are using getaddrinfo function then
socket creation should happen only after we
check if we received back valid addresses.
Hence socket creation should come after the call
to getaddrinfo
2. The listening server which pushes the events
to the webhook has to listen for both IPv4
and IPv6 messages as we would not be sure as to
what address family is picked in _gf_event.

glusterd: cksum mismatch on upgrading to latest gluster

2020-09-14T19:50:06+00:00

Issue:
In gluster versions less than 7, the checksums were calculated
whether or not the quota is enabled or not, and that cksum value
was also getting stored in the quota.cksum file. But, from gluster
7 version onwards cksum was calculated only if the quota is enabled.
Due to this, the cksums in quota.cksum files differ after upgrading.

Fix:
Added a check to see if the OP_VERSION is less than 7 then, follow
the previous method otherwise, move as per the latest changes for
cksum calculation.

This changes for the cksum calculation was done in
this commit : https://github.com/gluster/glusterfs/commit/3b5eb592f5

open-behind: implement create fop

2020-09-14T19:45:26+00:00

Open behind didn't implement create fop. This caused that files created
were not accounted for the number of open fd's. This could cause future
opens to be delayed when they shouldn't.

This patch implements the create fop. It also fixes a problem when
destroying the stack: when frame->local was not NULL, STACK_DESTROY()
tried to mem_put() it, which is not correct.

tests: provide an option to mark tests as 'flaky'

2020-09-14T19:41:21+00:00

* also add some time gap in other tests to see if we get things properly
* create a directory 'tests/000/', which can host any tests, which are flaky.
* move all the tests mentioned in the issue to above directory.
* as the above dir gets tested first, all flaky tests would be reported quickly.
* change `run-tests.sh` to continue tests even if flaky tests fail.

libglusterfs: fix dict leak

2020-09-07T04:52:58+00:00

Problem:
gf_rev_dns_lookup_cached() allocated struct dnscache->dict if it was null
but the freeing was left to the caller.

Fix:
Moved dict allocation and freeing into corresponding init and fini
routines so that its easier for the caller to avoid such leaks.
