* rpc: fix transport add/remove race on port probingMilind Changire2017-05-031-165/+196
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Spurious __gf_free() assertion failures seen all over the place with header->magic being overwritten when running port probing tests with 'nmap' Solution: Fix sequence of: 1. add accept()ed socket connection fd to epoll set 2. add newly created rpc_transport_t object in RPCSVC service list Correct sequence is #2 followed by #1. Reason: Adding new fd returned by accept() to epoll set causes an epoll_wait() to return immediately with a POLLIN event. This races ahead to a readv() which returms with errno:104 (Connection reset by peer) during port probing using 'nmap'. The error is then handled by POLLERR code to remove the new transport object from RPCSVC service list and later unref and destroy the rpc transport object. socket_server_event_handler() then catches up with registering the unref'd/destroyed rpc transport object. This is later manifest as assertion failures in __gf_free() with the header->magic field botched due to invalid address references. All this does not result in a Segmentation Fault since the address space continues to be mapped into the process and pages still being referenced elsewhere. As a further note: This race happens only in accept() codepath. Only in this codepath, the notify will be referring to two transports: 1, listener transport and 2. newly accepted transport All other notify refer to only one transport i.e., the transport/socket on which the event is received. Since epoll is ONE_SHOT another event won't arrive on the same socket till the current event is processed. However, in the accept() codepath, the current event - ACCEPT - and the new event - POLLIN/POLLER - arrive on two different sockets: 1. ACCEPT on listener socket and 2. POLLIN/POLLERR on newly registered socket. Also, note that these two events are handled different thread contexts. Cleanup: Critical section in socket_server_event_handler() has been removed. Instead, an additional ref on new_trans has been used to avoid ref/unref race when notifying RPCSVC.

* Halo Replication feature for AFR translatorKevin Vigor2017-05-022-2/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Halo Geo-replication is a feature which allows Gluster or NFS clients to write locally to their region (as defined by a latency "halo" or threshold if you like), and have their writes asynchronously propagate from their origin to the rest of the cluster. Clients can also write synchronously to the cluster simply by specifying a halo-latency which is very large (e.g. 10seconds) which will include all bricks. In other words, it allows clients to decide at mount time if they desire synchronous or asynchronous IO into a cluster and the cluster can support both of these modes to any number of clients simultaneously. There are a few new volume options due to this feature: halo-shd-latency: The threshold below which self-heal daemons will consider children (bricks) connected. halo-nfsd-latency: The threshold below which NFS daemons will consider children (bricks) connected. halo-latency: The threshold below which all other clients will consider children (bricks) connected. halo-min-replicas: The minimum number of replicas which are to be enforced regardless of latency specified in the above 3 options. If the number of children falls below this threshold the next best (chosen by latency) shall be swapped in. New FUSE mount options: halo-latency & halo-min-replicas: As descripted above. This feature combined with multi-threaded SHD support (D1271745) results in some pretty cool geo-replication possibilities. Operational Notes: - Global consistency is gaurenteed for synchronous clients, this is provided by the existing entry-locking mechanism. - Asynchronous clients on the other hand and merely consistent to their region. Writes & deletes will be protected via entry-locks as usual preventing concurrent writes into files which are undergoing replication. Read operations on the other hand should never block. - Writes are allowed from _any_ region and propagated from the origin to all other regions. The take away from this is care should be taken to ensure multiple writers do not write the same files resulting in a gfid split-brain which will require resolution via split-brain policies (majority, mtime & size). Recommended method for preventing this is using the nfs-auth feature to define which region for each share has RW permissions, tiers not in the origin region should have RO perms. TODO: - Synchronous clients (including the SHD) should choose clients from their own region as preferred sources for reads. Most of the plumbing is in place for this via the child_latency array. - Better GFID split brain handling & better dent type split brain handling (i.e. create a trash can and move the offending files into it). - Tagging in addition to latency as a means of defining which children you wish to synchronously write to Test Plan: - The usual suspects, clang, gcc w/ address sanitizer & valgrind - Prove tests Reviewers: jackl, dph, cjh, meyering Reviewed By: meyering Subscribers: ethanr Differential Revision: https://phabricator.fb.com/D1272053 Tasks: 4117827 Change-Id: I694a9ab429722da538da171ec528406e77b5e6d1 BUG: 1428061 Signed-off-by: Kevin Vigor <kvigor@fb.com> Reviewed-on: http://review.gluster.org/16099 Reviewed-on: https://review.gluster.org/16177 Tested-by: Pranith Kumar Karampuri <pkarampu@redhat.com> 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: Pranith Kumar Karampuri <pkarampu@redhat.com>
* rpc: add options to manage socket keepalive lifespanMilind Changire2017-04-122-42/+98
| | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Default values for handling socket timeouts for brick responses are insufficient for aggressive applications such as databases. Solution: Add 1:1 gluster options for keepalive, keepalive-idle, keepalive-interval and keepalive-timeout as per the socket level options available as per tcp(7) man page. Default values for options are NOT agressive and continue to be values which result in default timeout when only the keep alive option is turned on. These options are Linux specific and will not be applicable to the *BSDs.

* socket: retry connect immediately if it failsJeff Darcy2017-02-021-2/+36
| | | | | | | | | | | | | | | | | | | | | | Previously we relied on a complex dance of setting flags, shutting down the socket, tearing stuff down, getting an event, tearing more stuff down, and waiting for a higher-level retry. What we really need, in the case where we're just trying to connect prematurely e.g. to a brick that hasn't fully come up yet, is a simple retry of the connect(2) call. This was discovered by observing failures in ec-new-entry.t with multiplexing enabled, but probably fixes other random failures as well.

* core: run many bricks within one glusterfsd processJeff Darcy2017-01-301-2/+0
| | | | | | | | | | | | | | | | | | | | | | | This patch adds support for multiple brick translator stacks running in a single brick server process. This reduces our per-brick memory usage by approximately 3x, and our appetite for TCP ports even more. It also creates potential to avoid process/thread thrashing, and to improve QoS by scheduling more carefully across the bricks, but realizing that potential will require further work. Multiplexing is controlled by the "cluster.brick-multiplex" global option. By default it's off, and bricks are started in separate processes as before. If multiplexing is enabled, then *compatible* bricks (mostly those with the same transport options) will be started in the same process.

We barely support netbsd7 as it is. Note 2. Why is/was libgfxdr.so (.../rpc/xdr/src/...) linked with libglusterfs? A cut-and-paste mistake? It has no references to symbols in libglusterfs. Note3. "/#ifndef\|#define\|#endif/" (note the '\'s) is a _basic_ regex that matches the same lines as the _extended_ regex "/#(ifndef|define|endif)/". To match the extended regex sed needs to be run with -r on Linux; with -E on *BSD. However NetBSD's and FreeBSD's sed helpfully also provide -r for compatibility. Using a basic regex avoids having to use a kludge in order to run sed with the correct option on OS X. Note 4. Not copying the bit of xdrgen that inserts copyright/license boilerplate. AFAIK it's silly to pretend that machine generated files like these can be copyrighted or need license boilerplate. The XDR source files have their own copyright and license; and their copyrights are bound to be more up to date than old boilerplate inserted by a script. From what I've seen of other Open Source projects -- e.g. gcc and its C parser files generated by yacc and lex -- IIRC they don't bother to add copyright/license boilerplate to their generated files. It appears that it's a long-standing feature of make (SysV, BSD, gnu) for out-of-tree builds to helpfully pretend that the source files it can find in the VPATH "exist" as if they are in the $cwd. rpcgen doesn't work well in this situation and generates files with "bad" #include directives. E.g. if you `rpcgen ../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.x`, you get an #include directive in the generated .c file like this: ... #include "../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.h" ... which (obviously) results in compile errors on out-of-tree build because the (generated) header file doesn't exist at that location. Compared to `rpcgen ./glusterfs3-xdr.x` where you get: ... #include "glusterfs3-xdr.h" ... Which is what we need. We have to resort to some Stupid Make Tricks like the addition of various .PHONY targets to work around the VPATH "help". Warning: When doing an in-tree build, -I$(top_builddir)/rpc/xdr/... looks exactly like -I$(top_srcdir)/rpc/xdr/... Don't be fooled though. And don't delete the -I$(top_builddir)/rpc/xdr/... bits Change-Id: Iba6ab96b2d0a17c5a7e9f92233993b318858b62e BUG: 1330604 Signed-off-by: Kaleb S KEITHLEY <kkeithle@redhat.com> Reviewed-on: http://review.gluster.org/14085 Tested-by: Niels de Vos <ndevos@redhat.com> 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: Niels de Vos <ndevos@redhat.com>

* glusterd: add defence mechanism to avoid brick port clashesPrasanna Kumar Kalever2016-05-041-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intro: Currently glusterd maintain the portmap registry which contains ports that are free to use between 49152 - 65535, this registry is initialized once, and updated accordingly as an then when glusterd sees they are been used. Glusterd first checks for a port within the portmap registry and gets a FREE port marked in it, then checks if that port is currently free using a connect() function then passes it to brick process which have to bind on it. Problem: We see that there is a time gap between glusterd checking the port with connect() and brick process actually binding on it. In this time gap it could be so possible that any process would have occupied this port because of which brick will fail to bind and exit. Case 1: To avoid the gluster client process occupying the port supplied by glusterd : we have separated the client port map range with brick port map range more @ http://review.gluster.org/#/c/13998/ Case 2: (Handled by this patch) To avoid the other foreign process occupying the port supplied by glusterd : To handle above situation this patch implements a mechanism to return EADDRINUSE error code to glusterd, upon which a new port is allocated and try to restart the brick process with the newly allocated port. Note: Incase of glusterd restarts i.e. runner_run_nowait() there is no way to handle Case 2, becuase runner_run_nowait() will not wait to get the return/exit code of the executed command (brick process). Hence as of now in such case, we cannot know with what error the brick has failed to connect. This patch also fix the runner_end() to perform some cleanup w.r.t return values.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: when bind-insecure is 'off', all the clients bind to secure ports, if incase all the secure ports exhaust the client will no more bind to secure ports and tries gets a random port which is obviously insecure. we have seen the client obtaining a port number in the range 49152-65535 which are actually reserved as part of glusterd's pmap_registry for bricks, hence this will lead to port clashes between client and brick processes. Solution: If we can define different port ranges for clients incase where secure ports exhaust, we can avoid the maximum port clashes with in gluster processes. Still we are prone to have clashes with other non-gluster processes, but the chances being very low in the rhgs Env, but that's a different story on its own, which will be handled in upcoming patches.

* socket: Don't cleanup encrypted transport in socket_connect()Kaushal M2016-04-071-12/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ..instead cleanup only in socket_poller() With commit d117466 socket_poller() wasn't launched from socket_connect (for encrypted connections), if connect() failed. This was done to prevent the socket private data from being double unreffed, from the cleanups in both socket_poller() and socket_connect(). This allowed future reconnects to happen successfully. If a socket reconnects is sort of decided by the rpc notify function registered. The above change worked with glusterd, as the glusterd rpc notify function (glusterd_peer_rpc_notify()) continuously allowed reconnects on failure. mgmt_rpc_notify(), the rpc notify function in glusterfsd, behaves differently. For a DISCONNECT event, if more volfile servers are available or if more addresses are available in the dns cache, it allows reconnects. If not it terminates the program. For a CONNECT event, it attempts to do a volfile fetch rpc request. If sending this rpc fails, it immediately terminates the program. One side effect of commit d117466, was that the encrypted socket was registered with epoll, unintentionally, on a connect failure. A weird thing happens because of this. The epoll notifier notifies mgmt_rpc_notify() of a CONNECT event, instead of a DISCONNECT as expected. This causes mgmt_rpc_notify() to attempt an unsuccessful volfile fetch rpc request, and terminate. (I still don't know why the epoll raises the CONNECT event) Commit 46bd29e fixed some issues with IPv6 in GlusterFS. This caused address resolution in GlusterFS to also request of IPv6 addresses (AF_UNSPEC) instead of just IPv4. On most systems, this causes the IPv6 addresses to be returned first. GlusterD listens on 0.0.0.0:24007 by default. While this attaches to all interfaces, it only listens on IPv4 addresses. GlusterFS daemons and bricks are given 'localhost' as the volfile server. This resolves to '::1' as the first address. When using management encryption, the above reasons cause the daemon processes to fail to fetch volfiles and terminate. Solution -------- The solution to this is simple. Instead of cleaning up the encrypted socket in socket_connect(), launch socket_poller() and let it cleanup the socket instead. This prevents the unintentional registration with epoll, and socket_poller() sends the correct events to the rpc notify functions, which allows proper reconnects to happen.

The idea is with proper glusterd.vol configuration, 1. glusterd needs to listen on default port (240007) as IPv6 TCP listner. 2. Volume creation/deletion/mounting/add-bricks/delete-bricks/peer-probe needs to work using ipv6 addresses. 3. Bricks needs to listen on ipv6 addresses. All the above functionality is needed to say that glusterd supports ipv6 transport and this is broken. Fix: When "option transport.address-family inet6" option is present in glusterd.vol file, it is made sure that glusterd creates listeners using ipv6 sockets only and also the same information is saved inside brick volume files used by glusterfsd brick process when they are starting.

* build: fix ecdh.h and dh.h depsMilind Changire2015-11-162-7/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | openssl.ecdh.h and openssl/dh.h are not available on all platforms. This patch adds check to autoconf and updates relevant source files. Add missing #include "config.h" to socket.c to make HAVE_OPENSSL_DH_H and HAVE_OPENSSL_ECDH_H macros available. Definitions for UTIME_OMIT and UTIME_NOW in contrib/qemu/util/oslib-posix.c have been selected from /usr/include/bits/stat.h on Fedora 22 SSL context options SSL_OP_NO_TICKET and SSL_OP_NO_COMPRESSION are now conditionally set by testing their presence. glusterfs.spec.in file now adds CFLAGS=-DUSE_INSECURE_OPENSSL for RHEL < 6 in the %build section.

* build: install and package header files more conventionallyKaleb S. KEITHLEY2015-11-161-2/+0
| | | | | | | | | | | | | | The current way we install and package header files for the -devel package is a hack. This patch uses more conventional autoconf, libtool, and rpmbuild idioms to package -devel headers and libraries.

* core: use syscall wrappers instead of direct syscalls - miscellaneousKaleb S. KEITHLEY2015-10-281-22/+23
| | | | | | | | | | | | | | | various xlators and other components are invoking system calls directly instead of using the libglusterfs/syscall.[ch] wrappers. If not using the system call wrappers there should be a comment in the source explaining why the wrapper isn't used.

* all: reduce "inline" usageJeff Darcy2015-09-012-17/+17
| | | | | | | | | | | | | | | | | | | | | | | | | There are three kinds of inline functions: plain inline, extern inline, and static inline. All three have been removed from .c files, except those in "contrib" which aren't our problem. Inlines in .h files, which are overwhelmingly "static inline" already, have generally been left alone. Over time we should be able to "lower" these into .c files, but that has to be done in a case-by-case fashion requiring more manual effort. This part was easy to do automatically without (as far as I can tell) any ill effect. In the process, several pieces of dead code were flagged by the compiler, and were removed.
