w.gluster.org/10808 Tested-by: Gluster Build System <jenkins@build.gluster.com> Tested-by: NetBSD Build System Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> * glusterd: Ping timer implmentationKrishnan Parthasarathi2014-04-291-0/+1 | | | | | | | | | | | | | | | | | | | | | | | | This patch refactors the existing client ping timer implementation, and makes use of the common code for implementing both client ping timer and the glusterd ping timer. A new gluster rpc program for ping is introduced. The ping timer is only started for peers that have this new program. The deafult glusterd ping timeout is 30 seconds. It is configurable by setting the option 'ping-timeout' in glusterd.vol . Also, this patch introduces changes in the glusterd-handshake path. The client programs for a peer are now set in the callback of dump_versions, for both the older handshake and the newer op-version handshake. This is the only place in the handshake process where we know what programs a peer supports.

This header contains the uid, gid and auxiliary groups of the user/process that accesses the Gluster Volume. The AUTH_GLUSTERFS_V2 structure allows up to 65535 auxiliary groups to be passed on. Unfortunately, the RPC/AUTH header is limited to 400 bytes by the RPC specification: http://tools.ietf.org/html/rfc5531#section-8.2 In order to not cause complete failures on the client-side when trying to encode a AUTH_GLUSTERFS_V2 that would result in more than 400 bytes, we can calculate the expected size of the other elements: 1 | pid 1 | uid 1 | gid 1 | groups_len XX | groups_val (GF_MAX_AUX_GROUPS=65535) 1 | lk_owner_len YY | lk_owner_val (GF_MAX_LOCK_OWNER_LEN=1024) ----+------------------------------------------- 5 | total xdr-units one XDR-unit is defined as BYTES_PER_XDR_UNIT = 4 bytes MAX_AUTH_BYTES = 400 is the maximum, this is 100 xdr-units. XX + YY can be 95 to fill the 100 xdr-units. Note that the on-wire protocol has tighter requirements than the internal structures. It is possible for xlators to use more groups and a bigger lk_owner than that can be sent by a GlusterFS-client. This change prevents overflows when allocating the RPC/AUTH header. Two new macros are introduced to calculate the number of groups that fit in the RPC/AUTH header, when taking the size of the lk_owner in account. In case the list of groups exceeds the maximum possible, only the first groups are passed over the RPC/GlusterFS protocol to the bricks. A warning is added to the logs, so that most system administrators will get informed. The reducing of the number of groups is not a new inventions. The RPC/AUTH header (AUTH_SYS or AUTH_UNIX) that NFS uses has a limit of 16 groups. Most, if not all, NFS-clients will reduce any bigger number of groups to 16. (nfs.server-aux-gids can be used to workaround the limit of 16 groups, but the Gluster NFS-server will be limited to a maximum of 93 groups, or fewer in case the lk_owner structure contains more items.)
