2020-05-28crypto: engine - do not requeue in case of fatal errorIuliana Prodan
Now, in crypto-engine, if hardware queue is full (-ENOSPC), requeue request regardless of MAY_BACKLOG flag. If hardware throws any other error code (like -EIO, -EINVAL, -ENOMEM, etc.) only MAY_BACKLOG requests are enqueued back into crypto-engine's queue, since the others can be dropped. The latter case can be fatal error, so those cannot be recovered from. For example, in CAAM driver, -EIO is returned in case the job descriptor is broken, so there is no possibility to fix the job descriptor. Therefore, these errors might be fatal error, so we shouldn’t requeue the request. This will just be pass back and forth between crypto-engine and hardware.

2020-05-28perf/x86/rapl: Make perf_probe_msr() more robust and flexibleStephane Eranian
This patch modifies perf_probe_msr() by allowing passing of struct perf_msr array where some entries are not populated, i.e., they have either an msr address of 0 or no attribute_group pointer. This helps with certain call paths, e.g., RAPL. In case the grp is NULL, the default sysfs visibility rule applies which is to make the group visible. Without the patch, you would get a kernel crash with a NULL group.

2020-05-28perf/x86/rapl: Flip logic on default events visibilityStephane Eranian
This patch modifies the default visibility of the attribute_group for each RAPL event. By default if the grp.is_visible field is NULL, sysfs considers that it must display the attribute group. If the field is not NULL (callback function), then the return value of the callback determines the visibility (0 = not visible). The RAPL attribute groups had the field set to NULL, meaning that unless they failed the probing from perf_msr_probe(), they would be visible. We want to avoid having to specify attribute groups that are not supported by the HW in the rapl_msrs[] array, they don't have an MSR address to begin with. Therefore, we intialize the visible field of all RAPL attribute groups to a callback that returns 0. If the RAPL msr goes through probing and succeeds the is_visible field will be set back to NULL (visible). If the probing fails the field is set to a callback that return 0 (not visible).

The Texas Instruments K3 Multicore SoC platforms have chipid module which is represented by CTRLMMR_xxx_JTAGID register and contains information about SoC id and revision. Bits: 31-28 VARIANT Device variant 27-12 PARTNO Part number 11-1 MFG Indicates TI as manufacturer (0x17) 1 Always 1 This patch adds corresponding driver to identify the TI K3 SoC family and revision, and registers this information with the SoC bus. It is available under /sys/devices/soc0/ for user space, and can be checked, where needed, in Kernel using soc_device_match(). Identification is done by: - checking MFG to be TI ID - retrieving Device variant (revision) - retrieving Part number and convert it to the family - retrieving machine from DT "/model" Example J721E: # cat /sys/devices/soc0/{machine,family,revision} Texas Instruments K3 J721E SoC J721E SR1.0 Example AM65x: # cat /sys/devices/soc0/{machine,family,revision} Texas Instruments AM654 Base Board AM65X SR1.0 Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Reviewed-by: Lokesh Vutla <lokeshvutla@ti.com> Reviewed-by: Tero Kristo <t-kristo@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@oracle.com>

This is a bug fix and one of two places where I have found that the result of calling security_bprm_repopulate_creds more than once on different bprm->files depends on all of the bprm->files not just the file bprm->file. I intend to fix both of those cases and then modify the code to only call security_bprm_repopulate_creds on the final bprm file. So merge this change in so I hopefully reduce conflicts for others and I make it possible to build on top of this change. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>

2020-05-27ice: Check UMEM FQ size when allocating bufsKrzysztof Kazimierczak
If a UMEM is present on a queue when an interface/queue pair is being enabled, the driver will try to prepare the Rx buffers in advance to improve performance. However, if fill queue is shorter than HW Rx ring, the driver will report failure after getting the last address from the fill queue. This still lets the driver process the packets correctly during the NAPI poll, but leads to a constant NAPI rescheduling. Not allocating the buffers in advance would result in a potential performance decrease. Commit d57d76428ae9 ("xsk: Add API to check for available entries in FQ") provides an API that lets drivers check the number of addresses that the fill queue holds. Notify the user if fill queue is not long enough to prepare all buffers before packet processing starts, and allocate the buffers during the NAPI poll. If the fill queue size is sufficient, prepare Rx buffers in advance.

2020-05-27net/mlx5: DR, Split RX and TX lock for parallel insertionAlex Vesker
Change the locking flow to support RX and TX locks, splitting the single lock to two will allow inserting rules in parallel for RX and TX parts of the FDB. Locking the dr_domain will be done by locking the RX domain and the TX domain locks, this is mostly used for control operations on the dr_domain. When inserting rules for RX or TX the single nic_doamin RX or TX lock will be used. Splitting the lock is safe since RX and TX domains are logically separated from each other, shared objects such the send-ring and memory pool are protected by locks.
