Hello Miklos Szeredi,
This is a semi-automatic email about new static checker warnings.
The patch b9ac5c274b8c: "ovl: hash overlay non-dir inodes by copy up
origin" from Jul 4, 2017, leads to the following Smatch complaint:
fs/overlayfs/inode.c:603 ovl_get_inode()
warn: variable dereferenced before check 'lowerdentry' (see line 600)
fs/overlayfs/inode.c
599 if (!realinode)
600 realinode = d_inode(lowerdentry);
^^^^^^^^^^^
Old dereference.
601
602 if (!S_ISDIR(realinode->i_mode) &&
603 (upperdentry || (lowerdentry && ovl_indexdir(dentry->d_sb)))) {
^^^^^^^^^^^
New check added here.
604 struct inode *key = d_inode(lowerdentry ?: upperdentry);
605 unsigned int nlink;
regards,
dan carpenter
