* uss: disable memory accounting for the snapshot daemonRaghavendra Bhat2015-01-282-2/+3
| | | | | | | | | | | | | | | | | | * Bring in option to disable memory accounting for a glusterfs process This reverses the changes done by the commit 7fba3a88f1ced610eca0c23516a1e720d75160cd. * Change the key from "memory-accounting" to "no-memory-accounting", as by default all the glusterfs process enable memory accounting now. So to disable memory accounting for some process, "no-mem-accounting" argument has to be passed.

* api: versioned symbols in libgfapi.so for compatibilityKaleb S. KEITHLEY2015-01-1213-309/+818
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use versioned symbols to keep libgfapi at libgfapi.so.0.0.0 Revisited to address broken build on Mac OS X See http://review.gluster.org/9036 Rebased to include http://review.gluster.org/#/c/9376/ (glfs_resolve()) but note that gerrit's "Rebase Change" couldn't do it. N.B. noticed that glfs_get_volumeid() decl in glfs.h was missing the __THROW, added it. On systems using ELF and the GNU toolchain, symbol versions are created with a .symver asm operand in the .c source file. Clang is claimed to be compatible with gcc, so we'll pretend for now that this also works with clang. On Mac OS X, aliases are created with __asm "magic" in the .h header file. In the normal case, when both the decl and defn match, that's all that's needed. In our case though the decl and defn don't match --- we have, e.g. a defn such as 'int glfs_foo(...)' and the corresponding decl is 'int pub_glfs_foo(...)'. To make this work we create the necessary aliases in the library at link time with the -alias_list link option. Note that this results in there being pairs of symbols in the .dylib, e.g. _pub_glfs_foo and _glfs_foo$GFAPI_3.4.0. We could use another link option, -unexported_symbols_list to elide the _pub_glfs_* symbols. (And we probably should.) Linux symbol versioning was essentially copied from Solaris; in general I would expect this to "just work" on Solaris, but until someone tries we don't really know.

* gfapi: always close the fd in glfs_h_creat()Niels de Vos2014-12-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | When running stress and performance tests against nfs-ganesha, the number of open file descriptors increases continously. If the tests run long enough, the brick processes will eventually run out of file descriptors. This seems to be caused by glfs_h_creat() which allocates a 'struct glfs_fd', but does not release it. A normal glfs_creat() returns the file descriptor to the application, whereas glfs_h_creat() returns a handle (struct glfs_object). The file descriptor associated with the handle can not be release by glfapi-applications. This fd-leak can be prevented by destroying the 'struct glfs_fd' before returning the 'struct gfls_object' to the gfapi-application.

It stores this information in inode context. open and readv fop checks this flag from inode context. open and readv fop fails if split-brain flag is set for the file. USS uses gfapi to access snapshot volume. During open call gfapi internally calls glfs_resolve_component. glfs_resolve_component generates a new inode even if inode is present for the file.

* gNFS: Subdir mount does not work on UDP protoSantosh Kumar Pradhan2014-10-072-0/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After enabling nfs.mount-udp, mounting a subdir on a volume over NFS fails. Because mountudpproc3_mnt_3_svc() invokes nfs3_rootfh() which internally calls mnt3_mntpath_to_export() to resolve the mount path. mnt3_mntpath_to_export() just works if the mount path requested is volume itself. It is not able to resolve, if the path is a subdir inside the volume. MOUNT over TCP uses mnt3_find_export() to resolve subdir path but UDP can't use this routine because mnt3_find_export() needs the req data (of type rpcsvc_request_t) and it's available only for TCP version of RPC. FIX: (1) Use syncop_lookup() framework to resolve the MOUNT PATH by breaking it into components and resolve component-by-component. i.e. glfs_resolve_at () API from libgfapi shared object. (2) If MOUNT PATH is subdir, then make sure subdir export is not disabled. (3) Add auth mechanism to respect nfs.rpc-auth-allow/reject and subdir auth i.e. nfs.export-dir (4) Enhanced error handling for MOUNT over UDP Change-Id: I42ee69415d064b98af4f49773026562824f684d1 BUG: 1118311 Signed-off-by: Santosh Kumar Pradhan <spradhan@redhat.com> Reviewed-on: http://review.gluster.org/8346 Reviewed-by: soumya k <skoduri@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Niels de Vos <ndevos@redhat.com>

* make snapview-server more compatible with NFS serverRaghavendra Bhat2014-07-162-4/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * There was no handle based API for listxattr. With this change, glfs_h_getxattrs also handles the listxattr functionality by checking whether the name is NULL or not (like posix). But all the gfapi functions for listxattr (glfs_h_getxattrs AND glfs_listxattr AND glfs_flistxattr) returns the names of the xattrs in a buffer provided by the caller. But snapview-server has to return the list of xattrs in a dict itself (similar to posix xlator). But the buffer just contains the names of the xattrs. So for each xattr, a zero byte value is set (i.e. "") into the dict and sent back. Translators which do xattr caching (as of now md-cache which caches selinux and acl related xattrs) should not cache those xattrs whose value is a zero byte data (""). So made changes in md-cache to ignore zero byte values. * NFS server was not linking the inodes to inode table in readdirp. This was leading to applications getting errors. The below set of operations would lead to applications getting error 1) ls -l in one of the snaopshots (snapview-server would generate gfids for each entry on the fly and link the inodes associated with those entries) 2) NFS server upon getting readdirp reply would not link the inodes of the entries. But it used to generate filehandles for each entry and associate the gfid of that entry with the filehandle and send it as part of the reply to nfs client. 3) NFS client would send the filehandle of one of those entries when some activity is done on it. 4) NFS server would not be able to find the inode for the gfid present in the filehandle (as the inode was not linked) and would go for hard resolution by sending a lookup on the gfid by creating a new inode. 5) snapview-client will not able to identify whether the inode is a real inode existing in the main volume or a virtual inode existing in the snapshots as there would not be any inode context. 6) Since the gfid upon which lookup is sent is a virtual gfid which is not present in the disk, lookup would fail and the application would get an error. To handle above situation, now nfs server also does inode linking in readdirp.

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.

* log: enhance gluster log format with message ID and standardize errno reportingShyamsundarR2014-03-281-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there are quite a slew of logs in Gluster that do not lend themselves to trivial analysis by various tools that help collect and monitor logs, due to the textual nature of the logs. This FEAT is to make this better by giving logs message IDs so that the tools do not have to do complex log parsing to break it down to problem areas and suggest troubleshooting options. With this patch, a new set of logging APIs are introduced that take additionally a message ID and an error number, so as to print the message ID and the descriptive string for the error. New APIs: - gf_msg, gf_msg_debug/trace, gf_msg_nomem, gf_msg_callingfn These APIs follow the functionality of the previous gf_log* counterparts, and hence are 1:1 replacements, with the delta that, gf_msg, gf_msg_callingfn take additional parameters as specified above. Defining the log messages: Each invocation of gf_msg/gf_msg_callingfn, should provide an ID and an errnum (if available). Towards this, a common message id file is provided, which contains defines to various messages and their respective strings. As other messages are changed to the new infrastructure APIs, it is intended that this file is edited to add these messages as well. Framework enhanced: The logging framework is also enhanced to be able to support different logging backends in the future. Hence new configuration options for logging framework and logging formats are introduced. Backward compatibility: Currently the framework supports logging in the traditional format, with the inclusion of an error string based on the errnum passed in. Hence the shift to these new APIs would retain the log file names, locations, and format with the exception of an additional error string where applicable. Testing done: Tested the new APIs with different messages in normal code paths Tested with configurations set to gluster logs (syslog pending) Tested nomem variants, inducing the message in normal code paths Tested ident generation for normal code paths (other paths pending) Tested with sample gfapi program for gfapi messages Test code is stripped from the commit Pending work (not to be addressed in this patch (future)): - Logging framework should be configurable - Logging format should be configurable - Once all messages move to the new APIs deprecate/delete older APIs to prevent misuse/abuse using the same - Repeated log messages should be suppressed (as a configurable option) - Logging framework assumes that only one init is possible, but there is no protection around the same (in existing code) - gf_log_fini is not invoked anywhere and does very little cleanup (in existing code) - DOxygen comments to message id headers for each message Change-Id: Ia043fda99a1c6cf7817517ef9e279bfcf35dcc24 BUG: 1075611 Signed-off-by: ShyamsundarR <srangana@redhat.com> Reviewed-on: http://review.gluster.org/6547 Reviewed-by: Krutika Dhananjay <kdhananj@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Raghavendra G <rgowdapp@redhat.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>

This may not always be executed in same thread which executed [SYNCOP-1]) if (ret < 0) { if (errno != ENODATA) { loglevel = GF_LOG_ERROR; defrag->total_failures += 1; ..... } the function above could be executed by thread(t1) till [SYNCOP-1] and code from [ERRNO-2] can be executed by a different thread(t2) because of the way syncop-infra schedules the tasks. when the code is compiled with -O2 optimization this is the assembly code that is generated: [ERRNO-1] 1165 readdir_operrno = errno; <<---- errno gets expanded as *(__errno_location()) 0x00007fd149d48b60 <+496>: callq 0x7fd149d410c0 <address@hidden> 0x00007fd149d48b72 <+514>: mov %rax,0x50(%rsp) <<------ Address returned by __errno_location() is stored in a special location in stack for later use. 0x00007fd149d48b77 <+519>: mov (%rax),%eax 0x00007fd149d48b79 <+521>: mov %eax,0x78(%rsp) ....

So [ERRNO-2] ends up reading errno of t1 instead of errno of t2 even though t2 is executing [ERRNO-2] code section. When code is compiled without any optimization for [ERRNO-2]: 1281 if (errno != ENODATA) { 0x00007fd58e7a326f <+2237>: callq 0x7fd58e797300 <address@hidden><<--- As it is calling __errno_location() again it gets the location from t2 so it works as intended. 0x00007fd58e7a3274 <+2242>: mov (%rax),%eax 0x00007fd58e7a3276 <+2244>: cmp $0x3d,%eax 0x00007fd58e7a3279 <+2247>: je 0x7fd58e7a32a1 <gf_defrag_migrate_data+2287> Fix: Make syncop_xxx() return (-errno) value as the return value in case of errors and all the functions which make syncop_xxx() will need to use (-ret) to figure out the reason for failure in case of syncop_xxx() failures.

* build: Start using library versioning for various librariesHarshavardhana2014-01-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to libtool three individual numbers stand for CURRENT:REVISION:AGE, or C:R:A for short. The libtool script typically tacks these three numbers onto the end of the name of the .so file it creates. The formula for calculating the file numbers on Linux and Solaris is /path/to/library/<library_name>.(C - A).(A).(R) As you release new versions of your library, you will update the library's C:R:A. Although the rules for changing these version numbers can quickly become confusing, a few simple tips should help keep you on track. The libtool documentation goes into greater depth. In essence, every time you make a change to the library and release it, the C:R:A should change. A new library should start with 0:0:0. Each time you change the public interface (i.e., your installed header files), you should increment the CURRENT number. This is called your interface number. The main use of this interface number is to tag successive revisions of your API. The AGE number is how many consecutive versions of the API the current implementation supports. Thus if the CURRENT library API is the sixth published version of the interface and it is also binary compatible with the fourth and fifth versions (i.e., the last two), the C:R:A might be 6:0:2. When you break binary compatibility, you need to set AGE to 0 and of course increment CURRENT. The REVISION marks a change in the source code of the library that doesn't affect the interface-for example, a minor bug fix. Anytime you increment CURRENT, you should set REVISION back to 0.
