[PATCH v5 3/3] dm: prevent DAX mounts if not supported

by Ross Zwisler

Currently device_supports_dax() just checks to see if the QUEUE_FLAG_DAX flag is set on the device's request queue to decide whether or not the device supports filesystem DAX. Really we should be using bdev_dax_supported() like filesystems do at mount time. This performs other tests like checking to make sure the dax_direct_access() path works. We also explicitly clear QUEUE_FLAG_DAX on the DM device's request queue if any of the underlying devices do not support DAX. This makes the handling of QUEUE_FLAG_DAX consistent with the setting/clearing of most other flags in dm_table_set_restrictions(). Now that bdev_dax_supported() explicitly checks for QUEUE_FLAG_DAX, this will ensure that filesystems built upon DM devices will only be able to mount with DAX if all underlying devices also support DAX.

[PATCH v5 2/3] dax: bdev_dax_supported() check for QUEUE_FLAG_DAX

Add an explicit check for QUEUE_FLAG_DAX to __bdev_dax_supported(). This is needed for DM configurations where the first element in the dm-linear or dm-stripe target supports DAX, but other elements do not.

[PATCH 1/3] X.509: unpack RSA signatureValue field from BIT STRING

by David Howells

From: Maciej S. Szmigiero <mail(a)maciej.szmigiero.name> The signatureValue field of a X.509 certificate is encoded as a BIT STRING. For RSA signatures this BIT STRING is of so-called primitive subtype, which contains a u8 prefix indicating a count of unused bits in the encoding. We have to strip this prefix from signature data, just as we already do for key data in x509_extract_key_data() function. This wasn't noticed earlier because this prefix byte is zero for RSA key sizes divisible by 8. Since BIT STRING is a big-endian encoding adding zero prefixes has no bearing on its value. The signature length, however was incorrect, which is a problem for RSA implementations that need it to be exactly correct (like AMD CCP). Signed-off-by: Maciej S.

[PATCH v2] sched/rt: fix call to cpufreq_update_util

With commit 8f111bc357aa ("cpufreq/schedutil: Rewrite CPUFREQ_RT support") schedutil governor uses rq->rt.rt_nr_running to detect whether a RT task is currently running on the CPU and to set frequency to max if necessary. cpufreq_update_util() is called in enqueue/dequeue_top_rt_rq() but rq->rt.rt_nr_running as not been updated yet when dequeue_top_rt_rq() is called so schedutil still considers that a RT task is running when the last task is dequeued.

[PATCH 1/2] power: generic-adc-battery: fix out-of-bounds write when copying channel properties

by H. Nikolaus Schaller

We did have sporadic problems in the pinctrl framework during boot where a pin group name unexpectedly became NULL leading to a NULL dereference in strcmp. Detailled analysis of the failing cases did reveal that there were two devm allocated objects close to each other. The second one was the affected group_desc in pinmux and the first one was the psy_desc->properties buffer of the gab driver. Review of the gab code showed that the address calculation for one memcpy() is wrong. It does properties + sizeof(type) * index but C is defined to do the index multiplication already for pointer + integer additions. Hence the factor was applied twice and the memcpy() does write outside of the properties buffer. Sometimes it happened to be the pinctrl and triggered the strcmp(NULL). Anyways, it is overkill to use a memcpy() here instead of a simple assignment, which is easier to read and has less risk for wrong address calculations. So we change code to a simple assignment. If we initialize the index to the first free location, we can even remove the local variable 'properties'.

[PATCH V2 1/2] ata: Fix ZBC_OUT command block check

by Damien Le Moal

The block (LBA) specified must not exceed the last addressable LBA, which is dev->nr_sectors - 1. So fix the correct check is "if (block >= dev->n_sectors)" and not "if (block > dev->n_sectords)". Additionally, the asc/ascq to return for an LBA that is not a zone start LBA should be ILLEGAL REQUEST, regardless if the bad LBA is out of range.

[PATCH 0/2] ZBC_OUT command translation fixes

by Damien Le Moal

Tejun, These two patches fix problems with the checks of the ZBC_OUT command fields prior to its translation to ZAC MANAGEMENT OUT. The first patch fixes an incorrect out-of-range check and changes the returned asc/ascq to the ZBC defined INVALID FIELD IN CDB instead of (the more natural but incorrect) LBA OUT OF RANGE. The second patch disables the ZBC_OUT command block address check if the ALL bit is set, as defined by the ZBC specifications. Thank you for considering these patches for inclusion in 4.18 fixes (and CC stable).

Re: make a confirm for [usb: dwc3: gadget: skip Set/Clear Halt when invalid]

by liangshengjun

Hi balbi, Thanks for reponse. Now I fixed this case without check STALL status when clear-Halt request. BDW, I have meet other case: Run dwc3 for uvc function, the uvc video show video overlapping when windows 7 restart camera app. I debug the dwc3 drivers ,found : 1. when camera app close, the dwc3 ep_dequeue is call. Then giveback request with status: -ECONNRESET to uvc function layer. dep->trb_dequeue keep stable 2.when camera app reopen ,the dwc3 ep_queue is call. Then kick a transfer, fetch a new trb to dwc3 core. dep->trb_enqueue increment. 3.when one trb tranfter complete, handle event process function fetch one frb by current dep->trb_dequeue, and uvc function would get one request complete giveback, which have been dequeue. But in fact, current dep->trb_dequeue pointer buffer is "old", because stp1 have been dequeue it. Current dwc3 drivers: the correct enqueue req process is " ep enqueue > fetch a new trb by trb_enqueue > increase trb_enqueue > pack trb to dwc3 core", Right? For dequeue request process, now is " ep dequeue > stop started_list request > giveback request with -ECONNRESET status" Right ? To avoid getting a older request which has been dequeued, I think dequeue process necessary sync the trb_dequeue to trb_enqueue. Right ?

The weird thing here is that dwc3 has never suffered from this until we ran ADB against macOS. That was the only way to get any problems. Without clear halt, though, we have no means for syncing data toggle. -- balbi

Remove fpu lazy mode deadcode from 4.4.y

by Daniel Sangorrin

Hello Greg, #Forgot to add --compose Following up on our discussion during the review of kernel 4.4.138-stable, I have backported a few patches that remove the remaining FPU lazy mode deadcode from 4.4.y and 4.9.y. To avoid confusion I will send the explanation on separate e-mails: Patches for 4.4.y: [PATCH 1/4] KVM: x86: remove eager_fpu field of struct kvm_vcpu_arch - This is a git cherry-pick of 5a5fbdc0e3f1 ("KVM: x86: remove eager_fpu field of struct kvm_vcpu_arch"). It applies cleanly and is required for the next patch not to cause conflicts on arch/x86/kvm/cpuid.c [PATCH 2/4] x86/fpu: Remove use_eager_fpu() - The main conflict ocurred on fpu/core.c because commit bf15a8cf8d14 ("x86/fpu/xstate: Rename 'xstate_size' to 'fpu_kernel_xstate_size', to distinguish it from 'fpu_user_xstate_size'") is not on 4.4.y. That commit renames xstate_size to fpu_kernel_xstate_size but it also has its conflicts so I decided just to fix the conflict manually/ [PATCH 3/4] x86/fpu: Remove struct fpu::counter - caused one conflict because 4.4.y does not have commit d1898b733619 ("x86/fpu: Add tracepoints to dump FPU state at key points") I fixed it manually. [PATCH 4/4] x86/fpu: Finish excising 'eagerfpu' - caused a small conflict because 'nopku' is not in 4.4.y - sorry my editor might have removed a couple of trailing spaces automatically to Documentation/kernel-paramters.txt - cause one conflict in these files because they didn't exist arch/x86/include/asm/cpufeatures.h arch/x86/mm/pkeys.c tools/arch/x86/include/asm/cpufeatures.h - Instead I removed the X86_FEATURE_EAGER_FPU definition from arch/x86/include/asm/cpufeature.h Best regards, Daniel Sangorrin PS: Used git send-email --to stable(a)vger.kernel.org --cc-cmd="./scripts/get_maintainer.pl --norolestats" 2197a44..HEAD but it doesn't seem to work sorry...humm

The objtool and samples/bpf/ builds are disabled now that I'm switching from using the sources in a local volume to fetching them from a http server to build it inside the container, to make it easier to build in a container cluster. Those will come back later. Several are cross builds, the ones with -x-ARCH and the android one, and those may not have all the features built, due to lack of multi-arch devel packages, available and being used so far on just a few, like debian:experimental-x-{arm64,mipsel}. The 'perf test' one will perform a variety of tests exercising tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands with a variety of command line event specifications to then intercept the sys_perf_event syscall to check that the perf_event_attr fields are set up as expected, among a variety of other unit tests. Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/ with a variety of feature sets, exercising the build with an incomplete set of features as well as with a complete one.

Remove fpu lazy mode deadcode from 4.9.y

by Daniel Sangorrin

Hello Greg, Following up on our discussion during the review of kernel 4.4.138-stable, I have backported a few patches that remove the remaining FPU lazy mode deadcode from 4.4.y and 4.9.y. To avoid confusion I will send the explanation on separate e-mails: Patches for 4.9.y: [PATCH 1/4] x86/fpu: Remove use_eager_fpu() -> I only had to solve a small conflict caused by the fact that commit b22cbe404a9c ("x86/fpu: Fix invalid FPU ptrace state after execve()") had been applied before (it was supposed to come after) [PATCH 2/4] x86/fpu: Remove struct fpu::counter -> This is just a git cherry-pick of 3913cc350757 ("x86/fpu: Remove struct fpu::counter") which applies cleanly on 4.9.y. You can cherry-pick it instead of applying my patch. [PATCH 3/4] Revert "perf: sync up x86/.../cpufeatures.h" -> Sorry to revert your patch ;). This was just for the next patch to apply cleanly. [PATCH 4/4] x86/fpu: Finish excising 'eagerfpu' -> Again you can use a cherry pick of e63650840e8b ("x86/fpu: Finish excising 'eagerfpu'") instead of applying my patch. Tested on x86_64 only with: - ./runltp -f math (all tests pass) - IEEE 754 tests (no regressions seen) Ref: http://www.math.utah.edu/~beebe/software/ieee/ [Note] I could not prepare a x86 32-bit machine to test no387 [Note] If someone knows better about testing the FPU please let me know. Best regards, Daniel Sangorrin PS: Using git send-email --cc-cmd="scripts/get_maintainer.pl" for the first time. Apologies if this is not the right method.
