* fuse/md-cache: add support for the 'fopen-keep-cache' mount optionBrian Foster2012-07-132-1/+19
| | | | | | | | | | | | | | | | | | | | | | fopen-keep-cache disables unconditional page-cache invalidations on file open in fuse (via FOPEN_KEEP_CACHE) and replaces that behavior with detection of remote changes and explicit invalidations from mount/fuse. This option improves local caching through the page cache and native client. This change defines a new 'invalidate' translator callback to identify when an inode's cache mapping has been determined to be invalid. md-cache implements the policy to detect and invoke inode invalidations. fuse-bridge and io-cache implement invalidate handlers to invalidate the respective caches (page cache in the case of fuse).

* calls to dict_allocate_and_serialize() are not 64-bit cleanKaleb S. KEITHLEY2012-07-121-7/+7
| | | | | | | | | | | | | | | | | | | | | | | All calls to dict_allocate_and_serialize() pass the address of a 32-bit type, but must cast it to the 64-bit pointer type (size_t *). This happens to work on LE machines, but even if it's apparently benign, it's still a bug. On BE machines it is not benign. GF_PROTOCOL_DICT_SERIALIZE() hacks around it by creating a size_t temp var, but that's, well, a hack, IMO when you consider that all the callers are actually passing &<u_int>; the param should just be a u_int * and eliminate the buggy casts and the temp var in the macro. Nobody apparently uses the Fedora/EPEL PPC RPMs, but they might. People are trying to build gluster.org bits on SPARC and tripping over this.

* glusterfsd: don't ignore tmpfile write failure (2x)Jim Meyering2012-07-111-0/+7
| | | | | | | | | | | | | | | | | | | In both glusterfs_volfile_reconfigure and mgmt_getspec_cbk, we fwrite to a temporary file, fflush the stream, and then rewind and read from it. However, if either the fwrite or fflush were to fail, we would have ignored a write failure and would then read and process corrupt or incomplete input. In each case, add a test of ferror so that we don't ignore the write failure. Found by inspection.

* localtime and ctime are not MT-SAFEKaleb S. KEITHLEY2012-06-291-17/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a number of nit-level issues throughout the source with the use of localtime and ctime. While they apparently aren't causing too many problems, apart from the one in bz 828058, they ought to be fixed. Among the "real" problems that are fixed in this patch: 1) general localtime and ctime not MT-SAFE. There's a non-zero chance that another thread calling localtime (or ctime) will over-write the static data about to be used in another thread 2) localtime(& <64-bit-type>) or ctime(& <64-bit-type>) generally not a problem on 64-bit or little-endian 32-bit. But even though we probably have zero users on big-ending 32-bit platforms, it's still incorrect. 3) multiple nested calls passed as params. Last one wins, i.e. over- writes result of prior calls. 4) Inconsistent error handling. Most of these calls are for logging, tracing, or dumping. I submit that if an error somehow occurs in the call to localtime or ctime, the log/trace/dump still should still occur. 5) Appliances should all have their clocks set to UTC, and all log entries, traces, and dumps should use GMT. 6) fix strtok(), change to strtok_r() Other things this patch fixes/changes (that aren't bugs per se): 1) Change "%Y-%m-%d %H:%M:%S" and similar to their equivalent shorthand, e.g. "%F %T" 2) change sizeof(timestr) to sizeof timestr. sizeof is an operator, not a function. You don't use i +(32), why use sizeof(<var>). (And yes, you do use parens with sizeof(<type>).) 3) change 'char timestr[256]' to 'char timestr[32]' where appropriate. Per-thread stack is limited. Time strings are never longer than ~20 characters, so why waste 220+ bytes on the stack? Things this patch doesn't fix: 1) hodgepodge of %Y-%m-%d %H:%M:%S versus %Y/%m/%d-%H%M%S and other variations. It's not clear to me whether this ever matters, not to mention 3rd party log filtering tools may already rely on a particular format. Still it would be nice to have a single manifest constant and have every call to localtime/strftime consistently use the same format.

* fuse, glusterfsd: mount logic fixesCsaba Henk2012-05-211-5/+5

This patch fixes these issues by a refactor that merges the approaches sported by commits 7d0397c2 fuse: allow requests during mount (needed for SELinux labels) c5d781e0 upon daemonizing, wait on mtab update to terminate in parent Original daemonized libfuse event flow is as follows: try: fd = open("/dev/fuse") mount("-oopts,fd=%s" % fd ...) mount(8) -f # manipulate mtab except: sp = socketpair() env _FUSE_COMMFD=sp fusermount -oopts fd = receive_fd(sp) where fusermount(1) does: fd = open("/dev/fuse") mount("-oopts,fd=%d" % fd ...) sp = atoi(getenv("_FUSE_COMMFD")) send_fd(sp, fd) daemonize( # in child fuse_loop(fd) ) # in parent exit() As of 013850c9 (instead of adopting FUSE's 47e61004¹), we went for async mtab manipulation, and as of c5d781e0, still wanted keep that in sync with termination of daemon parent, so we changed it to: try: fd = open("/dev/fuse") mount("-oopts,fd=%s" % fd ...) pid = fork( # in child mount(8) -f ) except: sp = socketpair() env _FUSE_COMMFD=sp fusermount -oopts fd = receive_fd(sp) daemonize( fuse_loop(fd) ) waitpid(pid) exit() (Note the new approch came only to direct [privileged] mount, so fusermount based mounting was already partially broken.) As of 7d0397c2, with the purpose of facilitating async mount, the event flow was practically reduced to: fd = open("/dev/fuse") fork( mount("-oopts,fd=%s" % fd ...) fork( mount(8) -n ) ) daemonize( fuse_loop(fd) ) exit() Thus fusermount based mounting become defunct; however, the dead code was still kept around. So, we should either drop it or fix it. Also, the mtab manipulator is forked into yet another child with no purpose, while syncing with it in daemon parent is broken. mount(2) is neither synced with parent. Now we are coming to the following scheme: fd = open("/dev/fuse") pid = fork( try: mount("-oopts,fd=%s" % fd ...) mount(8) -n except: env _FUSE_DEVFD=fd fusermount -oopts ) where fusermount(1) does: fd = getenv("_FUSE_DEVFD") mount("-oopts,fd=%s" % fd ...) daemonize( fuse_loop(fd) ) waitpid(pid) exit() Nb.: - We can't help losing compatibility with upstream fusermount, as it sends back the fd only when mount(2) is completed, thus defeating the async mount approach. The 'getenv("_FUSE_DEVFD")' mechanism is specfic to glusterfs' fusermount (at the moment -- sure we can talk about it with upstream) - fusermount opens /dev/fuse at same privilege level as of original process², so we can bravely go on with doing the open unconditionally in original process - Original mounting code actually tries to mount through fusermount _twice_: if first attempt fails, then, assuming subtype support is missing in kernel, it tries again subtype stripped. However, this is redundant, as fusermount internally also performs the subtype check³. Therefore we simplified the logic to have just a single fusermount call. - we revert the changes to mount.glusterfs as of 7d0397c2, as now there is no issue with glusterfs to work around in that scope ¹ http://fuse.git.sourceforge.net/git/gitweb.cgi?p=fuse/fuse;a=blobdiff;f=ChangeLog;h=47e61004;hb=4c3d9b19;hpb=e61b775a ² http://fuse.git.sourceforge.net/git/gitweb.cgi?p=fuse/fuse;a=blob;f=util/fusermount.c;h=b2e87d95#l1023 ³ http://fuse.git.sourceforge.net/git/gitweb.cgi?p=fuse/fuse;a=blob;f=util/fusermount.c;h=b2e87d95#l839 Change-Id: I0c4ab70e0c5ad7b27337228749b266bcd0ba941d BUG: 811217 Signed-off-by: Csaba Henk <csaba@redhat.com> Reviewed-on: http://review.gluster.com/3341 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com> Reviewed-by: Anand Avati <avati@redhat.com>

* cli, glusterd, nfs: "volume status|profile|top" for nfs serversKaushal M2012-03-141-3/+244
| | | | | | | | | | | | | | | | | | | | | | Enables usage of volume monitoring operations "volume status", "volume top" and "volume profile" for nfs servers. These operations can be performed on nfs-servers by passing "nfs" as an option in cli. The output is similar to the normal brick outputs for these commands. The new syntaxes for the changed commands are as below, #gluster volume profile <VOLNAME> {start|info|stop} [nfs] #gluster volume top <VOLNAME> {[open|read|write|opendir|readdir [nfs]] |[read-perf|write-perf [nfs|{bs <size> count <count>}]]} [brick <brick>] [list-cnt <count>] #gluster volume status [all | <VOLNAME> [nfs|<BRICK>]] [detail|clients|mem|inode|fd|callpool] Change-Id: Ia6eb50c60aecacf9b413d3ea993f4cdd90ec0e07 BUG: 795267 Signed-off-by: Kaushal M <kaushal@redhat.com> Reviewed-on: http://review.gluster.com/2820 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Krishnan Parthasarathi <kp@gluster.com>
