* posix: perform readdir filling in locked regionAnand Avati2011-07-161-77/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
