* tests/rpm: always run ./autogen.sh to create missing filesNiels de Vos2014-05-232-7/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | In some occasions 'install-sh' seems to be missing in the 'make dist' tarball when ./autogen.sh has not been run (skipped when 'configure' exists). With this changes, 'autogen.sh' is always run so that missing files should get added to the tarball. Also write the logs from mock to a known location, and copy them to the '/var/log/' directory that Jenkins archives after a regression test failure. This makes it easier to find build issues that mock detects.

* rpc: implement server.manage-gids for group resolving on the bricksNiels de Vos2014-05-238-15/+254
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new volume option 'server.manage-gids' can be enabled in environments where a user belongs to more than the current absolute maximum of 93 groups. This option triggers the following behavior: 1. The AUTH_GLUSTERFS structure sent by GlusterFS clients (fuse, nfs or libgfapi) will contain only one (1) auxiliary group, instead of a full list. This reduces network usage and prevents problems in encoding the AUTH_GLUSTERFS structure which should fit in 400 bytes. 2. The single group in the RPC Calls received by the server is replaced by resolving the groups server-side. Permission checks and similar in lower xlators are applied against the full list of groups where the user belongs to, and not the single auxiliary group that the client sent.

* rpc: warn and truncate grouplist if RPC/AUTH can not hold everythingNiels de Vos2014-05-225-9/+160
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GlusterFS protocol currently uses AUTH_GLUSTERFS_V2 in the RPC/AUTH header. 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.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glfs object. Defined new APIs in the libgfapi module, given a glfs object, * to send handshake RPC call to glusterd process to fetch UUID of the volume * store it in the glusterfs_context linked to the glfs object. * to parse UUID from its cannonical string format into 16-byte array before sending it to the libgfapi users. Defined a RPC call in glusterd which can be used to query volume related info by other processes using 'clnt_handshake_procs'. Note - Currently this RPC call to glusterd process is used only to fetch UUID. But it can be extended to get other volume related structures as well. In addition to the above, defined a new variable to keep track of such handshake RPCs still in progress to make sure all the corresponding RPC callbacks have been processed before libgfapi returns the glfs object initialized. Also bumping up the GFAPI current version number since there is a new API "glfs_get_volume_id" defined and exposed by libgfapi as part of these changes.

* write-behind: track filesize when doing extending writesNiels de Vos2014-05-093-4/+301
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A program that calls mmap() on a newly created sparse file, may receive a SIGBUS signal. If SIGBUS is not handled, a segmentation fault will occur and the program will exit. A bug in the write-behind translator can cause the creation of a sparse file created with open(), seek(), write() to be cached. The last write() may not be sent to the server, until write-behind deems this necessary. * open(.., O_TRUNC, ...)/creat() the file, it is 0 bytes big * seek() into the file, use offset 31 * write() 1 byte to the file * the range from byte 0-30 are unwritten so called 'sparse' The following illustration tries to capture this: Legend: [ = start of file _ = unallocated/unwritten bytes # = allocated bytes in the file ] = end of file [_______________#] | | '- byte 0 '- byte 31 Without this change, reading from byte 0-30 will return an error, and reading the same area through an mmap()'d pointer will trigger a SIGBUS. Reading from this range did not trigger the outstanding write() to be flushed. The brick that receives the read() (translated over the network from mmap()) does not know that the file has been extended, and returns -EINVAL. This error gets transported back from the brick to the glusterfs-fuse client, and translated by the Linux kernel/VFS into SIGBUS triggered by mmap(). In order to solve this, a new attribute to the wb_inode structure is introduced; the current size of the file. All FOPs that can modify the size, are expected to update wb_inode->size. This makes it possible for extending writes with an offset bigger than EOF to mark the unwritten area as modified/pending.

A direntry is a dynamically sized structure, because the structure contains the name of the entry. The client sends a maximum size in the READDIR(P) Call to the server, and the server uses this size to limit the number of direntries to return. In case the server can pack more direntries in the requested maximum size (due to alignment differences between the architectures), it can happen that the client unpacks the list of direntries into a buffer that exceeds the maximum size that was given in the initial fuse-request. This change introduces a check for the maximum requested size of the fuse-response in fuse_readdir_cbk() and fuse_readdirp_cbk(). When the conversion from gluster-direntries to the fuse-direntry format takes place, the maximum size is checked, and the 'extra' direntries are discarded. The next readdir()/getdents() that is done, will fetch the just discarded direntries again. In addition to this bugfix, some extra logging in send_fuse_iov() and send_fuse_data() has been added to help diagnosing similar issues. This change combines two commits from master: > Commit: 20e317011af7c0f075819bf0648b225f6dc42350 > Change-Id: If2eecfcdf9c248f3820035601446d2c89ff9d1a1 > BUG: 1074023 > Signed-off-by: Niels de Vos <ndevos@redhat.com> > Reviewed-on: http://review.gluster.org/7278 > Tested-by: Gluster Build System <jenkins@build.gluster.com> > Reviewed-by: Xavier Hernandez <xhernandez@datalab.es> > Reviewed-by: Anand Avati <avati@redhat.com> > > Commit: 76ab97169f63da78c9e83daf040d7b09766497cf > Change-Id: Ic62d9d729a86a1a6a53ed1354fce153bac01d860 > BUG: 1074023 > Reported-by: Kaleb S.

| | | | | | | | | | | | | | | | | | | | | | Problem: Under the entry self heal, readlink is done at the source and sink. When readlink is done at the sink, because link is not present at the sink, afr expects ENOENT. AFR translator takes decisions for new link creation based on ENOENT but server translator is modified to return ESTALE because of which afr xlator is not able to heal. Fix: The check for inode absence at server includes ESTALE as well.

* rpcsvc: Ignore INODELK/ENTRYLK/LK for throttlingPranith Kumar K2014-05-081-16/+54
| | | | | | | | | | | | | | | | | | | | | | Problem: When iozone is in progress, number of blocking inodelks sometimes becomes greater than the threshold number of rpc requests allowed for that client (RPCSVC_DEFAULT_OUTSTANDING_RPC_LIMIT). Subsequent requests from that client will not be read until all the outstanding requests are processed and replied to. But because no more requests are read from that client, unlocks on the already granted locks will never come thus the number of outstanding requests would never come down. This leads to a ping-timeout on the client.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | posix_handle_mkdir_hashes() Whenever a new directory is created, its corresponding gfid file must also be created. This was done first calling MAKE_HANDLE_PATH() to get the path of the gfid file, then calling posix_handle_mkdir_hashes() to create the parent directories of the gfid, and finally creating the soft-link. In normal circumstances, the gfid we want to create won't exist and MAKE_HANDLE_PATH() will return a simple path to the new gfid. However if the volume is damaged and a self-heal is running, it is possible that we try to create an already existing gfid. In this case, MAKE_HANDLE_PATH() will return a path to the directory instead of the path to the gfid. To solve this problem, every time a path to a gfid is needed, a call to MAKE_HANDLE_ABSPATH() is made instead of the call to MAKE_HANDLE_PATH().

| | | | | | | | | | | | | | | | | | | | | | | Problem: For determining whether data-self-heal is needed afr takes blocking locks. So if self-heal is indeed in progress on the file, this leads to hangs. heal info hung for almost 50 minutes when a 50G file is undergoing heal. Fix: When self-heal is in progress there is a live self-heal-domain lock. In this stage if a non-blocking inodelk for self-heal-domain lock is performed it will fail with EAGAIN. For heal info we can use this logic to determing that the file is possibly undergoing heal and inform it to user instead of waiting for the completion of self-heal.
