When virtio-rng device was dropped by the hwrng core we were forced to wait the buffer to come back from the device to not have remaining ongoing operation that could spoil the buffer. But now, as the buffer is internal to the virtio-rng we can release the waiting loop immediately, the buffer will be retrieve and use when the virtio-rng driver will be selected again. This avoids to hang on an rng_current write command if the virtio-rng device is blocked by a lack of entropy. This allows to select another entropy source if the current one is empty. Signed-off-by:

hwrng core uses two buffers that can be mixed in the virtio-rng queue. If the buffer is provided with wait=0 it is enqueued in the virtio-rng queue but unused by the caller. On the next call, core provides another buffer but the first one is filled instead and the new one queued. And the caller reads the data from the new one that is not updated, and the data in the first one are lost. To avoid this mix, virtio-rng needs to use its own unique internal buffer at a cost of a data copy to the caller buffer. Signed-off-by:

For the devices which implement the get_vq_num_min callback, the driver should not negotiate with virtqueue size with the backend vdpa device if the value returned by get_vq_num_min equals to the value returned by get_vq_num_max.

No need to pre-allocate a big buffer for the IO SGL anymore. If a device has lots of deep queues, preallocation for the sg list can consume substantial amounts of memory. For HW virtio-blk device, nr_hw_queues can be 64 or 128 and each queue's depth might be 128. This means the resulting preallocation for the data SGLs is big. Switch to runtime allocation for SGL for lists longer than 2 entries. This is the approach used by NVMe drivers so it should be reasonable for virtio block as well. Runtime SGL allocation has always been the case for the legacy I/O path so this is nothing new. The preallocated small SGL depends on SG_CHAIN so if the ARCH doesn't support SG_CHAIN, use only runtime allocation for the SGL. Re-organize the setup of the IO request to fit the new sg chain mechanism. No performance degradation was seen (fio libaio engine with 16 jobs and 128 iodepth): IO size IOPs Rand Read (before/after) IOPs Rand Write (before/after) -------- --------------------------------- ---------------------------------- 512B 318K/316K 329K/325K 4KB 323K/321K 353K/349K 16KB 199K/208K 250K/275K 128KB 36K/36.1K 39.2K/41.7K Signed-off-by:

-F weight in perf script is broken. # ./perf mem record # ./perf script -F weight Samples for 'dummy:HG' event do not have WEIGHT attribute set. Cannot print 'weight' field. The sample type, PERF_SAMPLE_WEIGHT_STRUCT, is an alternative of the PERF_SAMPLE_WEIGHT sample type. They share the same space, weight. The lower 32 bits are exactly the same for both sample type. The higher 32 bits may be different for different architecture. For a new kernel on x86, the PERF_SAMPLE_WEIGHT_STRUCT is used. For an old kernel or other ARCHs, the PERF_SAMPLE_WEIGHT is used. With -F weight, current perf script will only check the input string "weight" with the PERF_SAMPLE_WEIGHT sample type. Because the commit ea8d0ed6 ("perf tools: Support PERF_SAMPLE_WEIGHT_STRUCT") didn't update the PERF_SAMPLE_WEIGHT_STRUCT sample type for perf script. For a new kernel on x86, the check fails. Use PERF_SAMPLE_WEIGHT_TYPE, which supports both sample types, to replace PERF_SAMPLE_WEIGHT Fixes: ea8d0ed6 ("perf tools: Support PERF_SAMPLE_WEIGHT_STRUCT") Reported-by:

When perf.data is not written cleanly, we would like to process existing data as much as possible (please see f_header.data.size == 0 condition in perf_session__read_header). However, perf.data with partial data may crash perf. Specifically, we see crash in 'perf script' for NULL session->header.env.arch. Fix this by checking session->header.env.arch before using it to determine native_arch. Also split the if condition so it is easier to read. Committer notes: If it is a pipe, we already assume is a native arch, so no need to check session->header.env.arch. Signed-off-by:

The Host Performance Buffer feature allows UFS read commands to carry the physical media addresses along with the LBAs, thus allowing less internal L2P-table switches in the device. HPB1.0 allowed a single LBA, while HPB2.0 increases this capacity up to 255 blocks. Carrying more than a single record, the read operation is no longer purely of type "read" but a "hybrid" command: Writing the physical address to the device in one operation and reading back the required payload in another. The JEDEC HPB spec defines two commands for this operation: HPB-WRITE-BUFFER (0x2) to write the physical addresses to device, and HPB-READ to read the payload. With the current HPB design the UFS driver has no alternative but to divide the READ request into 2 separate commands: HPB-WRITE-BUFFER and HPB-READ. This causes a great deal of aggravation to the block layer guys who demanded that we completely revert the entire HPB driver regardless of the huge amount of corporate effort already invested in it. As a compromise, remove only the pieces that implement the 2.0 specification. This is done as a matter of urgency for the final 5.15 release.

Testing revealed a problem with how the reference tag was handled for a WRITE_INSERT operation. The SCSI_PROT_REF_CHECK flag is not set when the controller is asked to generate the protection information (i.e. not DIX). And as a result the initial reference tag would not be set in the WRITE_INSERT case. Separate handling of the REF_CHECK and REF_INCREMENT flags to align with both the DIX spec and the MPI implementation.

When calling this function, all the shadow memory is already populated with kasan_early_shadow_pte which has PAGE_KERNEL protection. kasan_populate_early_shadow write-protects the mapping of the range of addresses passed in argument in zero_pte_populate, which actually write-protects all the shadow memory mapping since kasan_early_shadow_pte is used for all the shadow memory at this point. And then when using memblock API to populate the shadow memory, the first write access to the kernel stack triggers a trap. This becomes visible with the next commit that contains a fix for asan-stack. We already manually populate all the shadow memory in kasan_early_init and we write-protect kasan_early_shadow_pte at the end of kasan_init which makes the calls to kasan_populate_early_shadow superfluous so we can remove them.
