If "posix" (or synonym "unix" for backward compatibility) specified on mount, and server advertises support for SMB3.11 POSIX negotiate context, then enable the new posix extensions on the tcon. This can be viewed by looking for "posix" in the mount options displayed by /proc/mounts for that mount (ie if posix extensions allowed by server and the experimental POSIX extensions also requested on the mount by specifying "posix" at mount time). Also add check to warn user if conflicting unix/nounix or posix/noposix specified on mount. Signed-off-by: NSteve French <smfrench@gmail.com>

Unlike CIFS where UNIX/POSIX extensions had been negotiatable, SMB3 did not have POSIX extensions yet. Add the new SMB3.11 POSIX negotiate context to ask the server whether it can support POSIX (and thus whether we can send the new POSIX open context). Signed-off-by: NSteve French <smfrench@gmail.com>

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. Also cleans up a few build warnings about globals for various module parms. Signed-off-by: NSteve French <smfrench@gmail.com>

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: NSteve French <stfrench@microsoft.com> Acked-by: NRonnie Sahlberg <lsahlber@redhat.com>

In SMB2/SMB3 unlike in cifs we unnecessarily open the root of the share over and over again in various places during mount and path revalidation and also in statfs. This patch cuts redundant traffic (opens and closes) by simply keeping the directory handle for the root around (and reopening it as needed on reconnect), so query calls don't require three round trips to copmlete - just one, and eases load on network, client and server (on mount alone, cuts network traffic by more than a third). Also add a new cifs mount parm "nohandlecache" to allow users whose servers might have resource constraints (eg in case they have a server with so many users connecting to it that this extra handle per mount could possibly be a resource concern).

Using module_init() is wrong. E.g. ACPI adds and onlines memory before our memory notifier gets registered. This makes sure that ACPI memory detected during boot up will not result in a kernel crash. Easily reproducible with QEMU, just specify a DIMM when starting up.

We have to free memory again when we cancel onlining, otherwise a later onlining attempt will fail.
