2016-04-08orangefs: remove unused variableMartin Brandenburg1-3/+1

2016-03-31orangefs: don't put readdir slot twiceMartin Brandenburg1-5/+3
This was quite an oversight. After a readdir, the module could not be unloaded, the number of slots is wrong, and memory near the slot bitmap is possibly corrupt. Oops. Signed-off-by: Martin Brandenburg <martin@omnibond.com>
2016-03-26orangefs: saner calling conventions for getting a slotAl Viro1-3/+3
just have it return the slot number or -E... - the caller checks the sign anyway Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Mike Marshall <hubcap@omnibond.com>
2016-03-26orangefs: get rid of readdir_handle_sAl Viro1-63/+30
no point, really - we couldn't keep those across the calls of getdents(); it would be too easy to DoS, having all slots exhausted. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Mike Marshall <hubcap@omnibond.com>
2016-03-09Orangefs: add a new gossip statementMike Marshall1-0/+4

2016-02-25orangefs: free readdir buffer index before the dir_emit loopMartin Brandenburg1-25/+9
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.

2016-02-19orangefs_readdir_index_put(): get rid of bufmap argumentAl Viro1-8/+7

2016-01-15Orangefs: add verification to decode_direntsMike Marshall1-25/+93
Also add comments to decode_dirents and make it more readable. Signed-off-by: Mike Marshall <hubcap@omnibond.com>
2016-01-05orangefs: Fix some more global namespace pollution.Martin Brandenburg1-9/+14
This only changes the names of things, so there is no functional change. Signed-off-by: Martin Brandenburg <martin@omnibond.com> Signed-off-by: Mike Marshall <hubcap@omnibond.com>
2015-12-04Orangefs: change pvfs2 filenames to orangefsMike Marshall1-2/+2
Also changed references within source files that referred to header files whose names had changed. Signed-off-by: Mike Marshall <hubcap@omnibond.com>
2015-12-03OrangeFS: Change almost all instances of the string PVFS2 to OrangeFS.Yi Liu1-43/+43
OrangeFS was formerly known as PVFS2 and retains the name in many places. I leave the device /dev/pvfs2-req since this affects userspace. I leave the filesystem type pvfs2 since this affects userspace. Further the OrangeFS sysint library reads fstab for an entry of type pvfs2 independently of kernel mounts. I leave extended attribute keys user.pvfs2 and system.pvfs2 as the sysint library understands these. I leave references to userspace binaries still named pvfs2. I leave the filenames.

2015-11-13orangefs: validate the response in decode_dirents()Al Viro1-5/+32
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Mike Marshall <hubcap@omnibond.com>
2015-11-13orangefs: get rid of dec_string and enc_stringAl Viro1-7/+8
The latter is never used, the former has one user and would be better off spelled out right there. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Mike Marshall <hubcap@omnibond.com>
2015-11-13orangefs: switch decode_dirents() to use of kcalloc()Al Viro1-1/+1
gets rid of multiplication overflow Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Mike Marshall <hubcap@omnibond.com>
2015-10-05Orangefs: fix some checkpatch.pl complaints that had creeped in.Mike Marshall1-1/+1
Signed-off-by: Mike Marshall <hubcap@omnibond.com>
2015-10-03Orangefs: fix dir_emit code in pvfs2_readdir.Mike Marshall1-82/+49
Al Viro glanced at readdir and surmised that getdents would misbehave the way it was written... and sure enough. Signed-off-by: Mike Marshall <hubcap@omnibond.com>
2015-10-03Orangefs: address problems found by static checkerMike Marshall1-16/+0
Don't check for negative rc from boolean. Don't pointlessly initialize variables, it short-circuits gcc's uninitialized variable warnings. And max_new_nr_segs can never be zero, so don't check for it. Preserve original kstrdup pointer for freeing later. Don't check for negative value in unsigned variable.
