git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann: "As part of the cleanup of some remaining y2038 issues, I came to fs/compat_ioctl.c, which still has a couple of commands that need support for time64_t. In completely unrelated work, I spent time on cleaning up parts of this file in the past, moving things out into drivers instead. After Al Viro reviewed an earlier version of this series and did a lot more of that cleanup, I decided to try to completely eliminate the rest of it and move it all into drivers.

2019-11-26scsi: qla2xxx: unregister ports after GPN_FT failureMartin Wilck
When ports are lost due to unzoning them, and the initiator port is not part of any more zones, the GPN_FT command used for the fabric scan may fail. In this case, the current code simply gives up after a few retries. But if the zone is gone, all rports should actually be marked as lost. Fix this by jumping to the code that handles logout after GNN_FT after scan retries are exhausted.

2019-11-27nvme_fc: add module to ops template to allow module referencesJames Smart
In nvme-fc: it's possible to have connected active controllers and as no references are taken on the LLDD, the LLDD can be unloaded. The controller would enter a reconnect state and as long as the LLDD resumed within the reconnect timeout, the controller would resume. But if a namespace on the controller is the root device, allowing the driver to unload can be problematic. To reload the driver, it may require new io to the boot device, and as it's no longer connected we get into a catch-22 that eventually fails, and the system locks up. Fix this issue by taking a module reference for every connected controller (which is what the core layer did to the transport module). Reference is cleared when the controller is removed.

2019-11-21scsi: lpfc: size cpu map by last cpu id setJames Smart
Currently the lpfc driver sizes its cpu_map array based on num_possible_cpus(). However, that can be a value that is less than the highest cpu id bit that is set. As such, if a thread runs on a cpu with a larger cpu id, or for_each_possible_cpu() is used, the driver could index off the end of the array and return garbage or GPF. The driver maintains its own internal copy of the "num_possible" cpu value and sizes arrays by it. Fix by setting the driver's value to the value of the last cpu id bit set in the possible_mask - plus 1. Thus cpu_map will be sized to allow access by any cpu id possible.

If a faulty initiator fails to bind the socket to the iSCSI connection before emitting a command, for instance, a subsequent send_pdu, it will crash the kernel due to a null pointer dereference in sock_sendmsg(), as shown in the log below. This patch makes sure the bind succeeded before trying to use the socket.

2019-11-19scsi: pm80xx: Fix command issue sizingpeter chang
The commands to the controller are sent in fixed sized chunks which are set per-chip-generation and stashed in iomb_size. The driver fills in structs matching the register layout and memcpy this to memory shared with the controller. However, there are two problem cases: 1) Things like phy_start_req are too large because they share the sas_identify_frame definition with libsas, and it includes the crc word. This means that it's overwriting the start of the next command block, that's ok except if it happens at the end of the shared memory area. 2) Things like set_nvm_data_req which are shared between the HAL layers. This means that it's sending 'random' data for things that are in the reserved area. So far we haven't found a case where the controller FW cares, but sending possible gibberish (for most of the structures this is in the reserved area so previously zeroed) is not recommended.

As long as it's at least 500ms it doesn't matter what the scheduler is doing. The delay in the pm8001_exec_internal_task_abort does nothing, and theory is this is a delay to avoid a double-free.

2019-11-19scsi: ufs: Fix error handing during hibern8 enterSubhash Jadavani
During clock gating (ufshcd_gate_work()), we first put the link hibern8 by calling ufshcd_uic_hibern8_enter() and if ufshcd_uic_hibern8_enter() returns success (0) then we gate all the clocks. Now let’s zoom in to what ufshcd_uic_hibern8_enter() does internally: It calls __ufshcd_uic_hibern8_enter() and if failure is encountered, link recovery shall put the link back to the highest HS gear and returns success (0) to ufshcd_uic_hibern8_enter() which is the issue as link is still in active state due to recovery! Now ufshcd_uic_hibern8_enter() returns success to ufshcd_gate_work() and hence it goes ahead with gating the UFS clock while link is still in active state hence I believe controller would raise UIC error interrupts. But when we service the interrupt, clocks might have already been disabled! This change fixes for this by returning failure from __ufshcd_uic_hibern8_enter() if recovery succeeds as link is still not in hibern8, upon receiving the error ufshcd_hibern8_enter() would initiate retry to put the link state back into hibern8.
