2021-11-05smb3: add dynamic trace points for socket connectionSteve French
In debugging user problems with ip address/DNS issues with smb3 mounts, we sometimes needed additional info on the hostname and ip address. Add two tracepoints, one to show socket connection success and one for failures to connect to the socket. Sample output: mount.cifs-14551 [005] ..... 7636.547906: smb3_connect_done: conn_id=0x1 server=localhost addr=127.0.0.1:445 mount.cifs-14558 [004] ..... 7642.405413: smb3_connect_done: conn_id=0x2 server=smfrench.file.core.windows.net addr=52.239.158.232:445 mount.cifs-14741 [005] ..... 7818.490716: smb3_connect_done: conn_id=0x3 server=::1 addr=[::1]:445/0%0 mount.cifs-14810 [000] ..... 7966.380337: smb3_connect_err: rc=-101 conn_id=0x4 server=::2 addr=[::2]:445/0%0 mount.cifs-14810 [000] ..... 7966.380356: smb3_connect_err: rc=-101 conn_id=0x4 server=::2 addr=[::2]:139/0%0 mount.cifs-14818 [003] ..... 7986.771992: smb3_connect_done: conn_id=0x5 server=127.0.0.9 addr=127.0.0.9:445 mount.cifs-14825 [008] ..... 8008.178109: smb3_connect_err: rc=-115 conn_id=0x6 server=124.23.0.9 addr=124.23.0.9:445 mount.cifs-14825 [008] ..... 8013.298085: smb3_connect_err: rc=-115 conn_id=0x6 server=124.23.0.9 addr=124.23.0.9:139 cifsd-14553 [006] ..... 8036.735615: smb3_reconnect: conn_id=0x1 server=localhost current_mid=32 cifsd-14743 [010] ..... 8036.735644: smb3_reconnect: conn_id=0x3 server=::1 current_mid=29 cifsd-14743 [010] ..... 8039.921740: smb3_connect_err: rc=-111 conn_id=0x3 server=::1 addr=[::1]:445/0%0 cifsd-14553 [008] ..... 8042.993894: smb3_connect_err: rc=-111 conn_id=0x1 server=localhost addr=127.0.0.1:445 cifsd-14743 [010] ..... 8042.993894: smb3_connect_err: rc=-111 conn_id=0x3 server=::1 addr=[::1]:445/0%0 cifsd-14553 [008] ..... 8046.065824: smb3_connect_err: rc=-111 conn_id=0x1 server=localhost addr=127.0.0.1:445 cifsd-14743 [010] ..... 8046.065824: smb3_connect_err: rc=-111 conn_id=0x3 server=::1 addr=[::1]:445/0%0 cifsd-14553 [008] ..... 8049.137796: smb3_connect_done: conn_id=0x1 server=localhost addr=127.0.0.1:445 cifsd-14743 [010] ..... 8049.137796: smb3_connect_done: conn_id=0x3 server=::1 addr=[::1]:445/0%0 Reviewed-by: Paulo Alcantara (SUSE) <pc@cjr.nz> Signed-off-by: Steve French <stfrench@microsoft.com>

2021-11-05thermal: Fix NULL pointer dereferences in of_thermal_ functionsSubbaraman Narayanamurthy
of_parse_thermal_zones() parses the thermal-zones node and registers a thermal_zone device for each subnode. However, if a thermal zone is consuming a thermal sensor and that thermal sensor device hasn't probed yet, an attempt to set trip_point_*_temp for that thermal zone device can cause a NULL pointer dereference. Fix it. console:/sys/class/thermal/thermal_zone87 # echo 120000 > trip_point_0_temp ... Unable to handle kernel NULL pointer dereference at virtual address 0000000000000020 ...
