2016-03-09orangefs: Avoid symlink upcall if target is too long.Martin Brandenburg
Previously the client-core detected this condition by sheer luck! Since we used strncpy, no NUL byte would be included on the name. The client-core would call strlen, which would read past the end of its buffer, but return a number large enough that the client-core would return ENAMETOOLONG.

2016-02-26orangefs: remove unused 'diff' functionArnd Bergmann
orangefs contains a helper function to calculate the difference between two timeval structures. We are trying to remove all instances of timespec from the kernel, and this one is not used at all, so let's remove it now. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Mike Marshall <hubcap@omnibond.com>
2016-02-26orangefs: avoid time conversion functionArnd Bergmann
The new orangefs code uses a helper function to read a time field to its private structures from struct iattr. This will conflict with the move to 64-bit timestamps in the kernel and is generally not necessary. This replaces the conversion with a simple cast to time64_t that shows what is going on. As the orangefs-internal representation already uses 64-bit timestamps, there should be no ambiguity to negative values, and the cast ensures that we treat them as times before 1970 on both 32-bit and 64-bit architectures, rather than times after 2038. This patch keeps that behavior. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Mike Marshall <hubcap@omnibond.com>
2016-02-24orangefs: clean up fill_default_sys_attrsMartin Brandenburg
Size and type are read-only and not in the mask. The times were left unset despite being in the mask. We zero-fill the times since the server will fill them in and we will get the correct time when we fill the inode with getattr.

2016-02-24orangefs: free readdir buffer index before the dir_emit loopMartin Brandenburg
We only need it while the service operation is actually in progress since it is only used to co-ordinate the client-core's memory use. The kernel allocates its own space. Also clean up some comments which mislead the reader into thinking the readdir buffers are shared memory.

* turn all those list_del(&op->list) into list_del_init() * don't pick ops that are already given up in control device ->read()/->write_iter(). * have orangefs_clean_interrupted_operation() notice if op is currently being copied to/from daemon (by said ->read()/->write_iter()) and wait for that to finish. * when we are done copying to/from daemon and find that it had been given up while we were doing that, wake the waiting ..._clean_interrupted_... As the result, we are guaranteed that orangefs_clean_interrupted_operation(op) doesn't return until nobody else can see op. Moreover, we don't need to play with op refcounts anymore.

2016-02-19orangefs: sanitize handling of request listAl Viro
* checking that daemon is running (to decide whether we want to limit the timeout) should be done *after* the damn thing is included into the list; doing that before means that if the daemon gets shut down in between, we'll end up waiting indefinitely (== up to kill -9). * cancels should go into the head of the queue - the sooner they are picked, the less work daemon has to do and the sooner we get to free the slot held by aborted operation.

2016-02-19orangefs: delay freeing slot until cancel completesAl Viro
Make cancels reuse the aborted read/write op, to make sure they do not fail on lack of memory. Don't issue a cancel unless the daemon has seen our read/write, has not replied and isn't being shut down. If cancel *is* issued, don't wait for it to complete; stash the slot in there and just have it freed when cancel is finally replied to or purged (and delay dropping the reference until then, obviously).
