WORM-Xlator: Avoid performing fsetxattr if fd is NULL

2019-06-21T04:19:11+00:00

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 >= 0 . If an error happens we explicitly unwind

multiple files: another attempt to remove includes

2019-06-14T16:50:32+00:00

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.

WORM-Xlator: Maybe integer overflow when computing new atime

2019-03-07T12:04:12+00:00

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->ia_atime = time(NULL) + retention_state->ret_period;

stbuf->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.

libglusterfs: Move devel headers under glusterfs directory

2018-12-05T21:47:04+00:00

libglusterfs devel package headers are referenced in code using
include semantics for a program, this while it works can be better
especially when dealing with out of tree xlator builds or in
general out of tree devel package usage.

Towards this, the following changes are done,
- moved all devel headers under a glusterfs directory
- Included these headers using system header notation <> in all
code outside of libglusterfs
- Included these headers using own program notation "" within
libglusterfs

This change although big, is just moving around the headers and
making it correct when including these headers from other sources.

This helps us correctly include libglusterfs includes without
namespace conflicts.

Please review, it's not always just the comments that were fixed.
I've had to revert of course all calls to creat() that were changed
to create() ...

Only compile-tested!
