Calling cma_declare_contiguous_nid() with false exact_nid for per-numa reservation can easily cause cma leak and various confusion. For example, mm/hugetlb.c is trying to reserve per-numa cma for gigantic pages. But it can easily leak cma and make users confused when system has memoryless nodes. In case the system has 4 numa nodes, and only numa node0 has memory. if we set hugetlb_cma=4G in bootargs, mm/hugetlb.c will get 4 cma areas for 4 different numa nodes. since exact_nid=false in current code, all 4 numa nodes will get cma successfully from node0, but hugetlb_cma[1 to 3] will never be available to hugepage will only allocate memory from hugetlb_cma[0]. In case the system has 4 numa nodes, both numa node0&2 has memory, other nodes have no memory. if we set hugetlb_cma=4G in bootargs, mm/hugetlb.c will get 4 cma areas for 4 different numa nodes. since exact_nid=false in current code, all 4 numa nodes will get cma successfully from node0 or 2, but hugetlb_cma[1] and [3] will never be available to hugepage as mm/hugetlb.c will only allocate memory from hugetlb_cma[0] and hugetlb_cma[2]. This causes permanent leak of the cma areas which are supposed to be used by memoryless node. Of cource we can workaround the issue by letting mm/hugetlb.c scan all cma areas in alloc_gigantic_page() even node_mask includes node0 only. that means when node_mask includes node0 only, we can get page from hugetlb_cma[1] to hugetlb_cma[3]. But this will cause kernel crash in free_gigantic_page() while it wants to free page by: cma_release(hugetlb_cma[page_to_nid(page)], page, 1 << order) On the other hand, exact_nid=false won't consider numa distance, it might be not that useful to leverage cma areas on remote nodes. I feel it is much simpler to make exact_nid true to make everything clear. After that, memoryless nodes won't be able to reserve per-numa CMA from other nodes which have memory.

The routine hpage_nr_pages() was incorrectly used to calculate the number of base pages in a hugetlb page. hpage_nr_pages is designed to be called for THP pages and will return HPAGE_PMD_NR for hugetlb pages of any size. Due to the context in which hpage_nr_pages was called, it is unlikely to produce a user visible error. The routine with the incorrect call is only exercised in the case of hugetlb memory error or migration. In addition, this would need to be on an architecture which supports huge page sizes less than PMD_SIZE. And, the vma containing the huge page would also need to smaller than PMD_SIZE.

On a Chromebook I'm working on I noticed a big (~1 second) delay during bootup where nothing was happening. Right around this big delay there were messages about the TPM: [ 2.311352] tpm_tis_spi spi0.0: TPM ready IRQ confirmed on attempt 2 [ 3.332790] tpm_tis_spi spi0.0: Cr50 firmware version: ... I put a few printouts in and saw that tpm_tis_spi_init() (specifically tpm_chip_register() in that function) was taking the lion's share of this time, though ~115 ms of the time was in cr50_print_fw_version(). Let's make a one-line change to prefer async probe for tpm_tis_spi. There's no reason we need to block other drivers from probing while we load. NOTES: * It's possible that other hardware runs through the init sequence faster than Cr50 and this isn't such a big problem for them. However, even if they are faster they are still doing _some_ transfers over a SPI bus so this should benefit everyone even if to a lesser extent. * It's possible that there are extra delays in the code that could be optimized out. I didn't dig since once I enabled async probe they no longer impacted me.

The tpm2_get_cc_attrs_tbl() call will result in TPM commands being issued, which will need the use of the internal command/response buffer. But, we're issuing this *before* we've waited to make sure that buffer is allocated. This can result in intermittent failures to probe if the hypervisor / TPM implementation doesn't respond quickly enough. I find it fails almost every time with an 8 vcpu guest under KVM with software emulated TPM. To fix it, just move the tpm2_get_cc_attrs_tlb() call after the existing code to wait for initialization, which will ensure the buffer is allocated.

During flow control we are just reading from the TPM, yet our spi_xfer has the tx_buf and rx_buf both non-NULL which means we're requesting a full duplex transfer. SPI is always somewhat of a full duplex protocol anyway and in theory the other side shouldn't really be looking at what we're sending it during flow control, but it's still a bit ugly to be sending some "random" data when we shouldn't. The default tpm_tis_spi_flow_control() tries to address this by setting 'phy->iobuf[0] = 0'. This partially avoids the problem of sending "random" data, but since our tx_buf and rx_buf both point to the same place I believe there is the potential of us sending the TPM's previous byte back to it if we hit the retry loop. Another flow control implementation, cr50_spi_flow_control(), doesn't address this at all. Let's clean this up and just make the tx_buf NULL before we call flow_control(). Not only does this ensure that we're not sending any "random" bytes but it also possibly could make the SPI controller behave in a slightly more optimal way. NOTE: no actual observed problems are fixed by this patch--it's was just made based on code inspection.

It has been reported that some TIS based TPMs are giving unexpected errors when using the O_NONBLOCK path of the TPM device. The problem is that some TPMs don't like it when you get and then relinquish a locality (as the tpm_try_get_ops()/tpm_put_ops() pair does) without sending a command. This currently happens all the time in the O_NONBLOCK write path. Fix this by moving the tpm_try_get_ops() further down the code to after the O_NONBLOCK determination is made. This is safe because the priv->buffer_mutex still protects the priv state being modified.

Since 5.7, we've been using task_work to trigger async running of requests in the context of the original task. This generally works great, but there's a case where if the task is currently blocked in the kernel waiting on a condition to become true, it won't process task_work. Even though the task is woken, it just checks whatever condition it's waiting on, and goes back to sleep if it's still false. This is a problem if that very condition only becomes true when that task_work is run. An example of that is the task registering an eventfd with io_uring, and it's now blocked waiting on an eventfd read. That read could depend on a completion event, and that completion event won't get trigged until task_work has been run. Use the TWA_SIGNAL notification for task_work, so that we ensure that the task always runs the work when queued. Cc: stable@vger.kernel.org # v5.7 Signed-off-by: Jens Axboe <axboe@kernel.dk>

The patch turns "bool notify" into 0,TWA_RESUME,TWA_SIGNAL enum, the new TWA_SIGNAL flag implies signal_wake_up(). However, it needs to avoid the race with recalc_sigpending(), so the patch also adds the new JOBCTL_TASK_WORK bit included in JOBCTL_PENDING_MASK.

You can copy the former to the latter instead of running dt-mk-schema twice. This saves the cpu time a lot when you do 'make dt_binding_check dtbs_check' because building the full schema takes a couple of seconds. If DT_SCHEMA_FILES is specified, processed-schema.yaml is generated based on the specified yaml files.

Currently, processed-schema.yaml is always built, but it is actually used only for 'make dtbs_check'. 'make dt_binding_check' uses processed-schema-example.yaml instead. Build processed-schema.yaml only for 'make dtbs_check'.

We are having more and more schema files. Commit 8b6b8021 ("dt-bindings: Fix command line length limit calling dt-mk-schema") fixed the 'Argument list too long' error of the schema checks, but the same error happens while cleaning too. 'make clean' after 'make dt_binding_check' fails as follows: $ make dt_binding_check [ snip ] $ make clean make[2]: execvp: /bin/sh: Argument list too long make[2]: *** [scripts/Makefile.clean:52: __clean] Error 127 make[1]: *** [scripts/Makefile.clean:66: Documentation/devicetree/bindings] Error 2 make: *** [Makefile:1763: _clean_Documentation] Error 2 'make dt_binding_check' generates so many .example.dts, .dt.yaml files, which are passed to the 'rm' command when you run 'make clean'. I added a small hack to use the 'find' command to clean up most of the build artifacts before they are processed by scripts/Makefile.clean Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Link: https://lore.kernel.org/r/20200625170434.635114-2-masahiroy@kernel.orgSigned-off-by: Rob Herring <robh@kernel.org>

Since commit e69f5dc6 ("dt-bindings: serial: Convert 8250 to json-schema"), the schema for "ns16550a" is checked. 'make dt_binding_check' emits the following warning: uart@5,00200000: $nodename:0: 'uart@5,00200000' does not match '^serial(@[0-9a-f,]+)*$' Rename the node to follow the pattern defined in Documentation/devicetree/bindings/serial/serial.yaml While I was here, I removed leading zeros from unit names.

Sync with upstream dtc primarily to pickup the I2C bus check fixes. The interrupt_provider check is noisy, so turn it off for now. This adds the following commits from upstream: 9d7888cbf19c dtc: Consider one-character strings as strings 8259d59f59de checks: Improve i2c reg property checking fdabcf2980a4 checks: Remove warning for I2C_OWN_SLAVE_ADDRESS 2478b1652c8d libfdt: add extern "C" for C++ f68bfc2668b2 libfdt: trivial typo fix 7be250b4d059 libfdt: Correct condition for reordering blocks 81e0919a3e21 checks: Add interrupt provider test 85e5d839847a Makefile: when building libfdt only, do not add unneeded deps b28464a550c5 Fix some potential unaligned accesses in dtc Signed-off-by: Rob Herring <robh@kernel.org>

It's better to use /bin/sh instead of /bin/bash in order to run the tests in the BusyBox shell.

The reverted commit illegitly uses tpm2-tools. External dependencies are absolutely forbidden from these tests. There is also the problem that clearing is not necessarily wanted behavior if the test/target computer is not used only solely for testing.
