This will allow change GlusterFS to operate via IPv6 instead of IPv4 for all internal operations while still being able to serve (FUSE or NFS) clients via IPv4. - The changes apply to NFS as well. - This diff ports D1892990, D1897341 & D1896522 to the 3.8 branch.

| | | | | | | | | | | | | | | | | | | Problem: Commit ff075a3d6f9b142911d25c27fd209838782bfff0 disabled loading client-io-threads for replicate volumes (it was set to on by default in commit e068c1997314046658dd502e9118dab32decf879) due to performance issues but in doing so, inadvertently failed to load the xlator even if the user explicitly enabled the option using the volume set command. This was despite returning returning sucess for the volume set.

* event/epoll: don't call handler for events received after a pollerrRaghavendra G2017-09-061-6/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | we register socket with EPOLLONESHOT, which means it has to be explicitly added back through epoll_ctl to receive more events. Normally we do this once the handler completes processing of current event. But event_select_on_epoll is one asynchronous codepath where socket can be added back for polling while an event on the same socket is being processed. event_select_on_epoll has a check whether an event is being processed in the form of slot->in_handler. But this check is not sufficient enough to prevent parallel events as slot->in_handler is not atomically incremented with respect to reception of the event. This means following imaginary sequence of events can happen: * epoll_wait returns with a POLLERR - say POLLERR1 - on a socket (sock1) associated with slot s1. socket_event_handle_pollerr is yet to be invoked. * an event_select_on called from __socket_ioq_churn which was called in request/reply/msg submission codepath (as opposed to __socket_ioq_churn called as part of POLLOUT handling - we cannot receive a POLLOUT due to EPOLLONESHOT) adds back sock1 for polling. * since sock1 was added back for polling in step 2 and our polling is level-triggered, another thread picks up another POLLERR event - say POLLERR2. socket_event_handler is invoked as part of processing POLLERR2 and it completes execution setting priv->sock to -1. * event_unregister_epoll called as part of __socket_reset due to POLLERR1 would receive fd as -1 resulting in assert failure. Also, since the first pollerr event has done rpc_transport_unref, subsequent parallel events (not just pollerr, but other events too) could be acting on a freed up transport too.

This patch also fixes a race in dict_get_with_ref. Fix: Use dict_get_with_ref to retrieve the file contents.

These pid files should be seperate from configuration files. Deletion of the configuration file directory might result into serious problems. Also, /var/run/gluster is the default placeholder directory for pid files. So, with this fix Gluster will keep all process pid information of all processes in /var/run/gluster/* directory.

Solution: memcpy the setxattr value to the gluster buffer.

The behaviour for pthread_getspecific() is not defined in this case. This can happen when applications use mem-pools from libglusterfs.so, but did not call mem_pools_init_early(). By tracking the status of the mem-pools initialization, it is now possible to prevent calling pthread_getspecific() in case the pthread_key_t is not initialized. In future, we might want to exend this more to faciliate debugging.

* libglusterfs: the global_xlator should have valid cbksNiels de Vos2017-07-271-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a case where Gluster/NFS needs to resolve a path outside of the nfs-xlator itself. While resolving the path to fetch the GFID for creating the NFS-filehandle, gfapi may set an inode-ctx through glfs_resolve_at(). This inode-ctx is linked with the global_xlator. Because the global_xlator does not have any cbks, loc_wipe() will cause a segfault when it calls inode_unref() and xl->cbks->forget(). It is assumed that all xlators have a cbks symbol, otherwise loading of the xlator will fail. The global_xlator is not loaded in the same way, so there is no failure noticed when the instance is created. By adding an empty `struct xlator_cbks`, the global_xlator behaves similat to other xlators that do not implement all callbacks. I would have preferred to keep the inode-ctx setting through glfs_resolve_at() contained within Gluster/NFS. Unfortunately Gluster/NFS also uses the inode-ctx, and is not prepared to see the values that glfs_resolve_at() stores there. This problem is not easily reproducible because it involves mounting over WebNFS (like Solaris 10 can do). The segfault will also not be immediate, unless the following is done: 1. create a subdir on a volume 2. mount the volume/subdir over WebNFS 3. unmount the volume/subdir 4. mount the root of the volume 5. delete the subdir on the volume -> segfault of Gluster/NFS Change-Id: I2bd71d033e97edc07ba93b2d4ada558f65d68999 BUG: 1468291 Signed-off-by: Niels de Vos <ndevos@redhat.com> Reviewed-on: https://review.gluster.org/17897 Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Amar Tumballi <amarts@redhat.com> Reviewed-by: jiffin tony Thottan <jthottan@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Jeff Darcy <jeff@pl.atyp.us>
