* 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.

| | | | | | | | | | | | | | | | | | Since glusterfs uses xattr for storing gfid, and xattr support for symlinks and special files does not exist in solaris. The work around is provided by creating hidden files under export directory on solaris hosts only. the hidden files ares maintained in .glusterfs_xattr_inode directory, and all xattr ops on symlink and special files are redirected to respective inodes. All dir entries with name starting as .glusterfs (GF_HIDDEN_PATH) will not be shown in readdir ops. Signed-off-by: shishir gowda <shishirng@gluster.com> Signed-off-by: Anand V.
