* build: miscellaneous spelling fixesPatrick Matthäi2017-04-021-1/+1
| | | | | | | | | | | | | | | | | | Debian builds detected spelling issues with GlusterFS 3.10.1. Instead of carrying the patch in the Debian sources, let's include the fixes here too.

* posix: Fix creation of files with S_ISVTX on FreeBSDXavier Hernandez2017-02-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | On FreeBSD the S_ISVTX flag is completely ignored when creating a regular file. Since gluster needs to create files with this flag set, specialy for DHT link files, it's necessary to force the flag. This fix does this by calling fchmod() after creating a file that must have this flag set. > Change-Id: I51eecfe4642974df6106b9084a0b144835a4997a > BUG: 1411228 > Signed-off-by: Xavier Hernandez <xhernandez@datalab.es> > Reviewed-on: https://review.gluster.org/16417 > Smoke: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Raghavendra Bhat <raghavendra@redhat.com> > Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com> Change-Id: I2087516383bd132c59bbab98eda8f2243a2163fe BUG: 1424973 Signed-off-by: Xavier Hernandez <xhernandez@datalab.es> Reviewed-on: https://review.gluster.org/16686 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra Bhat <raghavendra@redhat.com> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com>
* cluster/ec: fix selinux issues with mmap()Xavier Hernandez2017-02-061-46/+175
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. > Change-Id: I71c2f88be4e4d795b6cfff96ab3799c362c54291 > BUG: 1402661 > Signed-off-by: Xavier Hernandez <xhernandez@datalab.es> > Reviewed-on: https://review.gluster.org/16405 > Smoke: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Jeff Darcy <jdarcy@redhat.com> Change-Id: I5c2dd51b1161505316c8f78b73e9a585d0c115d0 BUG: 1418650 Signed-off-by: Xavier Hernandez <xhernandez@datalab.es> Reviewed-on: https://review.gluster.org/16522 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com>
* cluster/ec: Add support for hardware accelerationXavier Hernandez2016-09-081-0/+904
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.
