<title>WORM-Xlator: Initial write of a file succeeds if auto-commit-period 0</title>

<content type='text'>
If worm-file-level enabled and auto-commit-period 0 an initial write
of a file (e.g. $ echo test &gt;&gt; file1.txt) would lead to an zero byte
file because the WORM xlator immediately WORMed the file when it was
created.

To avoid this we move the setting of trusted.worm_file from
worm_create_cbk to worm_release . This means that this xattr will set
when the filehandle is closed and all initial WRITE FOPs succeed.

Finally we also perform gf_worm_state_transition in worm_release to
ensure that the file will be immediately WORMed after the file handle
was closed.

We were cleaning xlator from botton to top, which might
lead to problems when upper xlators trying to access
the xlator object loaded below.

One such scenario is when fd_unref happens as part of the
fini call which might lead to calling the releasedir to
lower xlator. This will lead to invalid mem access

<title>WORM-Xlator: Avoid performing fsetxattr if fd is NULL</title>

If worm_create_cbk receives an error (op_ret == -1) fd will be NULL
and therefore performing fsetxattr would lead to a segfault and the
brick process crashes. To avoid this we allow setting fsetxattr only
if op_ret &gt;= 0 . If an error happens we explicitly unwind

There are many include statements that are not needed.
A previous more ambitious attempt failed because of *BSD plafrom
(see https://review.gluster.org/#/c/glusterfs/+/21929/ )

Now trying a more conservative reduction.
It does not solve all circular deps that we have, but it
does reduce some of them. There is just too much to handle
reasonably (dht-common.h includes dht-lock.h which includes
dht-common.h ...), but it does reduce the overall number of lines
of include we need to look at in the future to understand and fix
the mess later one.

<title>WORM-Xlator: Maybe integer overflow when computing new atime</title>

The structs worm_reten_state_t and read_only_priv_t from read-only.h are
using uint64_t values to store periods of retention and autocommmit.
This seems to be dangerous since in worm-helper.c the function
worm_set_state computes in line 97:

stbuf-&gt;ia_atime = time(NULL) + retention_state-&gt;ret_period;

stbuf-&gt;ia_atime is using int64_t because of the settings of struct
iattr. So if there is a very very high retention period stored, there
is maybe an integer overflow.

What can be the solution? Using int64_t instead if uint64_t may reduce
the probability of the occurance.
