* multiple files: another attempt to remove includesYaniv Kaul2019-06-141-2/+0
| | | | | | | | | | | | | | | | | | 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.

* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* all: fix warnings on non 64-bits architecturesXavi Hernandez2018-10-101-2/+2
| | | | | | | | | | When compiling in other architectures there appear many warnings. Some of them are actual problems that prevent gluster to work correctly on those architectures.

* cluster/ec: fix selinux issues with mmap()Xavier Hernandez2017-02-021-11/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | EC uses mmap() to create a memory area for the dynamic code. Since the code is created on the fly and executed when needed, this region of memory needs to have write and execution privileges. This combination is not allowed by default by selinux. To solve the problem a file is used as a backend storage for the dynamic code and it's mapped into two distinct memory regions, one with write access and the other one with execution access. This approach is the recommended way to create dynamic code by a program in a more secure way, and selinux allows it. Additionally selinux requires that the backend file be stored in a directory marked with type bin_t to be able to map it in an executable area. To satisfy this condition, GLUSTERFS_LIBEXECDIR has been used. This fix also changes the error check for mmap(), that was done incorrectly (it checked against NULL instead of MAP_FAILED), and it also correctly propagates the error codes and makes sure they aren't silently ignored.

* cluster/ec: Add support for hardware accelerationXavier Hernandez2016-09-081-8/+22
| | | | | | | | | | | | | | | | | | | | | | | 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.

* ec: Removed SSE2 dependencyXavier Hernandez2014-09-111-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | This patch implements the Galois Field multiplications using pure C code without any assembler support. This makes the ec xlator portable to other architectures. In the future it will be possible to use an optimized implementation of the multiplications using architecture dependent facilities (it will be automatically detected and configured). To allow bricks with different machine word sizes to be able to work seamlessly in the same volume, the minimum fragment length to be stored in any brick has been fixed to 512 bytes. Otherwise, different implementations will corrupt the data (SSE2 used 128 bytes, while new implementation would have used 64). This patch also removes the '-msse2' option added on patch http://review.gluster.org/8395/ Change-Id: Iaf6e4ef3dcfda6c68f48f16ca46fc4fb61a215f4 BUG: 1125166 Signed-off-by: Xavier Hernandez <xhernandez@datalab.es> Reviewed-on: http://review.gluster.org/8413 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Dan Lambright <dlambrig@redhat.com>
