In test cases where an instance of the driver is detached and reattached, the driver will crash on reattachment. There is a compound if statement that will skip over the bar setup if the pci_resource_start call is not successful. The driver erroneously returns success to its bar setup in this scenario even though the bars aren't properly configured. Rework the offending code segment for proper initialization steps. If the pci_resource_start call fails, -ENOMEM is now returned.

XRI_ABORTED_CQE completions were not being handled in the fast path. They were being queued and deferred to the lpfc worker thread for processing. This is an artifact of the driver design prior to moving queue processing out of the isr and into a workq element. Now that queue processing is already in a deferred context, remove this artifact and process them directly.

Hardware queues are a fast staging area to push commands into the adapter. The adapter should drain them extremely quickly. However, under heavy io load, the host cpu is pushing commands faster than the drain rate of the adapter causing the driver to resource busy commands. Enlarge the hardware queue (wq & cq) to support a larger number of queue entries (4x the prior size) before backpressure. Enlarging the queue requires larger contiguous buffers (16k) per logical page for the hardware. This changed calling sequences that were expecting 4K page sizes that now must pass a parameter with the page sizes. It also required use of a new version of an adapter command that can vary the page size values.

There is no need to #define the license of the driver, just put it in the MODULE_LICENSE() line directly as a text string. This allows tools that check that the module license matches the source code license to work properly, as there is no need to unwind the unneeded dereference, especially when the string is defined in a .h file far away from the .c file it is used in.

The TW_IOCTL_GET_LOCK ioctl uses do_gettimeofday() to check whether a lock has expired. This can misbehave due to a concurrent settimeofday() call, as it is based on 'real' time, and it will overflow in y2038 on 32-bit architectures, producing unexpected results when used across the overflow time. This changes it to using monotonic time, using ktime_get() to simplify the code. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Adam Radford <aradford@gmail.com> Signed-off-by: Martin K.

The calculation of the number of seconds since Sunday 00:00:00 overflows in 2106, meaning that we instead will return the seconds since Wednesday 06:28:16 afterwards. Using 64-bit time stamps avoids this slight inconsistency, and the deprecated do_gettimeofday(), replacing it with the simpler ktime_get_real_seconds().

twl_aen_queue_event/twa_aen_queue_event, we use do_gettimeofday() to read the lower 32 bits of the current time in seconds, to pass them to the TW_IOCTL_GET_NEXT_EVENT ioctl or the 3ware_aen_read sysfs file. This will overflow on all architectures in year 2106, there is not much we can do about that without breaking the ABI. User space has 90 years to learn to deal with it, so it's probably ok. I'm changing it to use ktime_get_real_seconds() with a comment to document what happens when.

bfa_aen_entry_s is passed through a netlink socket that can be read by either 32-bit or 64-bit processes, but the data format is different between the two on current implementations. Originally, this was using a 'struct timeval', which also suffers from getting redefined with a new libc implementation. With this patch, the layout gets fixed to having two 64-bit members for the time, making it the same on 32-bit kernels and 64-bit kernels running either compat or native user space including x32. Provided that the new header file gets used to recompile any 32-bit application binaries, this will fix running those on a 64-bit kernel (with or without this patch) e.g. in a container environment, and it will make binaries work that will be built against a future 32-bit glibc that uses a 64-bit time_t, and avoid the y2038 overflow there. However, this also breaks compatibility with any existing 32-bit binary running on a native 32-bit kernel, those must be recompiled against the new header, which in turn makes them incompatible with older kernels unless the same change gets applied there. Obviously this patch should only be applied when the benefits outweigh the possible breakage. I'm posting it under the assumption that there are no open-source tools using the netlink interface, and that users of the binaries provided by qlogic for SLES10/11 and RHEL5/6 are not actually being used on new future systems with 32-bit x86 kernels.

bfa_aen_entry_s is passed to user space in a netlink message, but is defined using a 'struct timeval' and an 'enum' that are not only different between architectures, but also between 32-bit user space and 64-bit kernels they may run on, as well as depending on the particular C library that defines timeval. This changes the in-kernel definition to no longer use the timeval type directly but instead use two open-coded 'unsigned long' members. This keeps the existing ABI, but making the variable unsigned also helps make it work after y2038, until it overflows in 2106. Since the macro becomes overly complex at this point, I'm changing it to an inline function for readability. I'm not changing the 32-bit user-space ABI at this point, to keep the changes separate, I deally this would be defined using the same binary layout for all architectures.

The bfa_get_log_time() returns a 64-bit timestamp that does not suffer from the y2038 overflow on 64-bit systems. However, on 32-bit architectures the timestamp will jump from 0x000000007fffffff to 0xffffffff80000000 in y2038 and produce wrong results. The ktime_get_real_seconds() function does the same thing as bfa_get_log_time() without that problem, so we can simply remove the former use ktime_get_real_seconds() instead.

io_profile_start_time() gets read using do_gettimeofday() and passed down as a 32-bit value through multiple functions. This will overflow in y2038 or y2106, depending on whether it gets interpreted as unsigned in the end. This changes do_gettimeofday() to ktime_get_real_seconds() and pushes the point at which it overflows to where we actually assign it to the bfa_fcpim_del_itn_stats_s structure, with an appropriate comment.

In bfa_ioc_send_enable, we use the deprecated do_gettimeofday() function to read the current time. This is not a problem, since the firmware interface is already limited to 32-bit timestamps, but it's better to use ktime_get_seconds() and document what the limitation is. I noticed that I did the same change in commit a5af8392 ("bna: avoid writing uninitialized data into hw registers") for the ethernet driver. That commit also changed the "disable" funtion to initialize the data we pass to the firmware properly, so I'm doing the same thing here.

We use the deprecated do_gettimeofday() function to read the current time when resetting the statistics in both bfa_port and bfa_svc. This works fine because overflow is handled correctly, but we want to get rid of do_gettimeofday() and using a non-monotonic time suffers from concurrent settimeofday calls and other problems. This uses the ktime_get_seconds() function instead, which does what we need here.

BFA_TRC_TS() calculates a 32-bit microsecond timestamp using the deprecated do_gettimeofday() function. This overflows roughly every 71 minutes, so it's obviously not used as an absolute time stamp, but it seems wrong to use a time base for it that will jump during settimeofday() calls, leap seconds, or the y2038 overflow. This converts it to ktime_get_ts64(), which has none of those problems but is not synchronized to wall-clock time.

Pull powerpc fixes from Michael Ellerman: "A small batch of fixes, about 50% tagged for stable and the rest for recently merged code. There's one more fix for the >128T handling on hash. Once a process had requested a single mmap above 128T we would then always search above 128T. The correct behaviour is to consider the hint address in isolation for each mmap request. Then a couple of fixes for the IMC PMU, a missing EXPORT_SYMBOL in VAS, a fix for STRICT_KERNEL_RWX on 32-bit, and a fix to correctly identify P9 DD2.1 but in code that is currently not used by default.

Pull SCSI target updates from Nicholas Bellinger: "This series is predominantly bug-fixes, with a few small improvements that have been outstanding over the last release cycle. As usual, the associated bug-fixes have CC' tags for stable. Also, things have been particularly quiet wrt new developments the last months, with most folks continuing to focus on stability atop 4.x stable kernels for their respective production configurations. Also at this point, the stable trees have been synced up with mainline. This will continue to be a priority, as production users tend to run exclusively atop stable kernels, a few releases behind mainline. The highlights include: - Fix PR PREEMPT_AND_ABORT null pointer dereference regression in v4.11+ (tangwenji) - Fix OOPs during removing TCMU device (Xiubo Li + Zhang Zhuoyu) - Add netlink command reply supported option for each device (Kenjiro Nakayama) - cxgbit: Abort the TCP connection in case of data out timeout (Varun Prakash) - Fix PR/ALUA file path truncation (David Disseldorp) - Fix double se_cmd completion during ->cmd_time_out (Mike Christie) - Fix QUEUE_FULL + SCSI task attribute handling in 4.1+ (Bryant Ly + nab) - Fix quiese during transport_write_pending_qf endless loop (nab) - Avoid early CMD_T_PRE_EXECUTE failures during ABORT_TASK in 3.14+ (Don White + nab)" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (35 commits) tcmu: Add a missing unlock on an error path tcmu: Fix some memory corruption iscsi-target: Fix non-immediate TMR reference leak iscsi-target: Make TASK_REASSIGN use proper se_cmd->cmd_kref target: Avoid early CMD_T_PRE_EXECUTE failures during ABORT_TASK target: Fix quiese during transport_write_pending_qf endless loop target: Fix caw_sem leak in transport_generic_request_failure target: Fix QUEUE_FULL + SCSI task attribute handling iSCSI-target: Use common error handling code in iscsi_decode_text_input() target/iscsi: Detect conn_cmd_list corruption early target/iscsi: Fix a race condition in iscsit_add_reject_from_cmd() target/iscsi: Modify iscsit_do_crypto_hash_buf() prototype target/iscsi: Fix endianness in an error message target/iscsi: Use min() in iscsit_dump_data_payload() instead of open-coding it target/iscsi: Define OFFLOAD_BUF_SIZE once target: Inline transport_put_cmd() target: Suppress gcc 7 fallthrough warnings target: Move a declaration of a global variable into a header file tcmu: fix double se_cmd completion target: return SAM_STAT_TASK_SET_FULL for TCM_OUT_OF_RESOURCES ...
