this function does the same thing as add build_path_from_dentry() but takes a boolean parameter to decide whether or not to prefix the path with the tree name. we cannot rely on tcon->Flags & SMB_SHARE_IS_IN_DFS for SMB2 as smb2 code never sets tcon->Flags but it sets tcon->share_flags and it seems the SMB_SHARE_IS_IN_DFS has different semantics in SMB2: the prefix shouldn't be added everytime it was in SMB1.

since the DFS payload is not tied to the SMB version we can: * isolate the DFS payload in its own struct, and include that struct in packet structs * move the function that parses the response to misc.c and make it work on the new DFS payload struct (add payload size and utf16 flag as a result).

The recent changes that added SMB3 encryption support introduced a possible use after free in the demultiplex thread. When we process an encrypted packed we obtain a pointer to SMB session but do not obtain a reference. This can possibly lead to a situation when this session was freed before we copy a decryption key from there. Fix this by obtaining a copy of the key rather than a pointer to the session under a spinlock.

Currently all the p_paddr of PT_LOAD headers are assigned to 0, which is not true and could be misleading, since 0 is a valid physical address. User space tools like makedumpfile needs to know physical address for PT_LOAD segments of direct mapped regions. Therefore this patch updates paddr for such regions. It also sets an invalid paddr (-1) for other regions, so that user space tool can know whether a physical address provided in PT_LOAD is correct or not. I do not know why it was 0, which is a valid physical address. But certainly, it might break some user space tools, and those need to be fixed. For example, see following code from kexec-tools kexec/kexec-elf.c:build_mem_phdrs() if ((phdr->p_paddr + phdr->p_memsz) < phdr->p_paddr) { /* The memory address wraps */ if (probe_debug) { fprintf(stderr, "ELF address wrap around\n"); } return -1; } We do not need to perform above check for an invalid physical address. I think, kexec-tools and makedumpfile will need fixup. I already have those fixup which will be sent upstream once this patch makes through. Pro with this approach is that, it will help to calculate variable like page_offset, phys_base from PT_LOAD even when they are randomized and therefore will reduce many variable and version specific values in user space tools. Having an ASLR offset information can help to translate an identity mapped virtual address to a physical address. But that would be an additional field in PT_LOAD header structure and an arch dependent value. Moreover, sending a valid physical address like 0 does not seem right. So, IMHO it is better to fix that and send valid physical address when available (identity mapped).

GUI environments seem to be becoming more agressive at scanning filesystems, to the point where autofs cannot expire mounts at all. This is one key reason the update of the autofs dentry info last_used field is done in the expire system when the dentry is seen to be in use. But somewhere along the way instances of the update has crept back into the autofs path walk functions which, with the more aggressive file access patterns, is preventing expiration. Changing the update in the path walk functions allows autofs to at least make progress in spite of frequent immediate re-mounts from file accesses.
