storage/posix: fill 'ia_ino' from 'ia_gfid' to preserve same ino number

2011-10-24T06:00:48+00:00

take the least significant 64bit from gfid and assign it to 'ia_ino',
hence for a given file (or directory), the 'ia_ino' number is always
same.

posix: perform readdir filling in locked region

2011-07-16T19:47:30+00:00

When two application threads share an open dir fd (DIR *) and issue
readdirs, storage/posix will receive separate readdir fops in separate
threads in parallel. This has two-fold issues

1. In the following pair of operations -

   entry = readdir(dir)
       and
   strcpy (gf_dirent->name, entry->d_name)

   @entry is a static buffer in libc which can get reused by another thread
   to get filled with a longer name. This can cause the second operation
   to overflow the buffer as the allocation was for the smaller name.

2. In the following pair of operations -

   seekdir (dir, offset)
      and
   entry = readdir(dir)

   If two threads are executing these sequence in parallel in separate
   threads, then one of them will end up reading wrong/unexpected entries.

It would be sufficient to fix 1. by using readdir_r but that still keeps
the second race open. Hence the patch moves all the set of operations to a
locked region which solves both races.

storage/posix: set all keys present in 'params' dict while creating an entry

2011-07-13T06:16:54+00:00

so, there is no need to do a 'setxattr()' after entry creation, which could now
fail due to ACL on server side.
