2018-06-04CIFS: Fix signing for SMB2/3Aurelien Aptel3-10/+12
It seems Ronnie's preamble removal broke signing. the signing functions are called when: A) we send a request (to sign it) B) when we recv a response (to check the signature). On code path A, the smb2 header is in iov[1] but on code path B, the smb2 header is in iov[0] (and there's only one vector). So we have different iov indexes for the smb2 header but the signing function always use index 1. Fix this by checking the nb of io vectors in the signing function as a hint.

To improve security it may be helpful to have additional ways to restrict the ability to override the default dialects (SMB2.1, SMB3 and SMB3.02) on mount with old dialects (CIFS/SMB1 and SMB2) since vers=1.0 (CIFS/SMB1) and vers=2.0 are weaker and less secure. Add a module parameter "disable_legacy_dialects" (/sys/module/cifs/parameters/disable_legacy_dialects) which can be set to 1 (or equivalently Y) to forbid use of vers=1.0 or vers=2.0 on mount.

Although dmesg logs and wireshark network traces can be helpful, being able to dynamically enable/disable tracepoints (in this case via the kernel ftrace mechanism) can also be helpful in more quickly debugging problems, and more selectively tracing the events related to the bug report. This patch adds 12 ftrace tracepoints to cifs.ko for SMB3 events in some obvious locations. Subsequent patches will add more as needed. Example use: trace-cmd record -e cifs <run test case> trace-cmd show Various trace events can be filtered. See: trace-cmd list | grep cifs for the current list of cifs tracepoints. Sample output (from mount and writing to a file): root@smf:/sys/kernel/debug/tracing/events/cifs# trace-cmd show <snip> mount.cifs-6633 [006] .... 7246.936461: smb3_cmd_done: pid=6633 tid=0x0 sid=0x0 cmd=0 mid=0 mount.cifs-6633 [006] .... 7246.936701: smb3_cmd_err: pid=6633 tid=0x0 sid=0x3d9cf8e5 cmd=1 mid=1 status=0xc0000016 rc=-5 mount.cifs-6633 [006] .... 7246.943055: smb3_cmd_done: pid=6633 tid=0x0 sid=0x3d9cf8e5 cmd=1 mid=2 mount.cifs-6633 [006] .... 7246.943298: smb3_cmd_done: pid=6633 tid=0xf9447636 sid=0x3d9cf8e5 cmd=3 mid=3 mount.cifs-6633 [006] .... 7246.943446: smb3_cmd_done: pid=6633 tid=0xf9447636 sid=0x3d9cf8e5 cmd=11 mid=4 mount.cifs-6633 [006] .... 7246.943659: smb3_cmd_done: pid=6633 tid=0xe1b781a sid=0x3d9cf8e5 cmd=3 mid=5 mount.cifs-6633 [006] .... 7246.943766: smb3_cmd_done: pid=6633 tid=0xe1b781a sid=0x3d9cf8e5 cmd=11 mid=6 mount.cifs-6633 [006] .... 7246.943937: smb3_cmd_done: pid=6633 tid=0xe1b781a sid=0x3d9cf8e5 cmd=5 mid=7 mount.cifs-6633 [006] .... 7246.944020: smb3_cmd_done: pid=6633 tid=0xe1b781a sid=0x3d9cf8e5 cmd=16 mid=8 mount.cifs-6633 [006] .... 7246.944091: smb3_cmd_done: pid=6633 tid=0xe1b781a sid=0x3d9cf8e5 cmd=16 mid=9 mount.cifs-6633 [006] .... 7246.944163: smb3_cmd_done: pid=6633 tid=0xe1b781a sid=0x3d9cf8e5 cmd=16 mid=10 mount.cifs-6633 [006] .... 7246.944218: smb3_cmd_err: pid=6633 tid=0xf9447636 sid=0x3d9cf8e5 cmd=11 mid=11 status=0xc0000225 rc=-2 mount.cifs-6633 [006] .... 7246.944219: smb3_fsctl_err: xid=0 fid=0xffffffffffffffff tid=0xf9447636 sid=0x3d9cf8e5 class=0 type=393620 rc=-2 mount.cifs-6633 [007] .... 7246.944353: smb3_cmd_done: pid=6633 tid=0xe1b781a sid=0x3d9cf8e5 cmd=16 mid=12 bash-2071 [000] .... 7256.903844: smb3_cmd_done: pid=2071 tid=0xe1b781a sid=0x3d9cf8e5 cmd=5 mid=13 bash-2071 [000] .... 7256.904172: smb3_cmd_done: pid=2071 tid=0xe1b781a sid=0x3d9cf8e5 cmd=16 mid=14 bash-2071 [000] .... 7256.904471: smb3_cmd_done: pid=2071 tid=0xe1b781a sid=0x3d9cf8e5 cmd=17 mid=15 bash-2071 [000] .... 7256.904950: smb3_cmd_done: pid=2071 tid=0xe1b781a sid=0x3d9cf8e5 cmd=5 mid=16 bash-2071 [000] .... 7256.905305: smb3_cmd_done: pid=2071 tid=0xe1b781a sid=0x3d9cf8e5 cmd=17 mid=17 bash-2071 [000] .... 7256.905688: smb3_cmd_done: pid=2071 tid=0xe1b781a sid=0x3d9cf8e5 cmd=6 mid=18 bash-2071 [000] .... 7256.905809: smb3_write_done: xid=0 fid=0xd628f511 tid=0xe1b781a sid=0x3d9cf8e5 offset=0x0 len=0x1b Signed-off-by: Steve French <stfrench@microsoft.com> Acked-by: Ronnie Sahlberg <lsahlber@redhat.com>
