https://bugzilla.kernel.org/show_bug.cgi?id=199185 Eric Biggers (ebiggers3@xxxxxxxxx) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ebiggers3@xxxxxxxxx --- Comment #4 from Eric Biggers (ebiggers3@xxxxxxxxx) --- The above patch is wrong; it makes ext4_get_acl() always fail with ERANGE, because ext4_get_acl() uses buffer=NULL and buffer_size=0 to get the size of the xattr. Likewise getxattr(..., NULL, 0) is broken. I think we should check 'size' against XATTR_SIZE_MAX in the !buffer case instead. Also checking 'size < 0' is unnecessary since 'size' is unsigned. -- You are receiving this mail because: You are watching the assignee of the bug.
