[PATCH 1/3] arm64: perf: Mark expected switch fall-through

by Anders Roxell

When fall-through warnings was enabled by default, commit d93512ef0f0e ("Makefile: Globally enable fall-through warning"), the following warnings was starting to show up: ../arch/arm64/kernel/hw_breakpoint.c: In function ‘hw_breakpoint_arch_parse’: ../arch/arm64/kernel/hw_breakpoint.c:540:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if (hw->ctrl.len == ARM_BREAKPOINT_LEN_1) ^ ../arch/arm64/kernel/hw_breakpoint.c:542:3: note: here case 2: ^~~~ ../arch/arm64/kernel/hw_breakpoint.c:544:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if (hw->ctrl.len == ARM_BREAKPOINT_LEN_2) ^ ../arch/arm64/kernel/hw_breakpoint.c:546:3: note: here default: ^~~~~~~ Rework so that the compiler doesn't warn about fall-through. Rework so the code looks like the arm code. Since the comment in the function indicates taht this is supposed to behave the same way as arm32 because it handles 32-bit tasks also.

Specifically, moving a software group to a hardware context would violate the exclusivity rules if both groups contain matching exclusive events. This attempt was, however, unsuccessful: the check that we have in the perf_event_open() syscall is both wrong (looks at wrong PMU) and insufficient (group leader may still be exclusive), as can be illustrated by running: $ perf record -e '{intel_pt//,cycles}' uname $ perf record -e '{cycles,intel_pt//}' uname ultimately successfully. Furthermore, we are completely free to trigger the exclusivity violation by: perf -e '{cycles,intel_pt//}' -e '{intel_pt//,instructions}' even though the helpful perf record will not allow that, the ABI will. The warning later in the perf_event_open() path will also not trigger, because it's also wrong. Fix all this by validating the original group before moving, getting rid of broken safeguards and placing a useful one to perf_install_in_context().

[PATCH] arm: perf: Mark expected switch fall-through

by Anders Roxell

When fall-through warnings was enabled by default, d93512ef0f0e ("Makefile: Globally enable fall-through warning"), we could see the following warnings was starting to show up. However, this was originally introduced in commit 6ee33c2712fc ("ARM: hw_breakpoint: correct and simplify alignment fixup code"). Commit d968d2b801d8 ("ARM: 7497/1: hw_breakpoint: allow single-byte watchpoints on all addresses") was written with the intent to allow single-byte watchpoints on all addresses but forgot to move 'case 1:' down below 'case 2:'. ../arch/arm/kernel/hw_breakpoint.c: In function ‘hw_breakpoint_arch_parse’: ../arch/arm/kernel/hw_breakpoint.c:609:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if (hw->ctrl.len == ARM_BREAKPOINT_LEN_2) ^ ../arch/arm/kernel/hw_breakpoint.c:611:3: note: here case 3: ^~~~ ../arch/arm/kernel/hw_breakpoint.c:613:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if (hw->ctrl.len == ARM_BREAKPOINT_LEN_1) ^ ../arch/arm/kernel/hw_breakpoint.c:615:3: note: here default: ^~~~~~~ Rework so 'case 1:' are next to 'case 3:' and also add '/* Fall through */' so that the compiler doesn't warn about fall-through.

WTF: patch "[PATCH] gpio: em: remove the gpiochip before removing the irq domain" was seriously submitted to be applied to the 5.2-stable tree?

by gregkh＠linuxfoundation.org

The patch below was submitted to be applied to the 5.2-stable tree. I fail to see how this patch meets the stable kernel rules as found at Documentation/process/stable-kernel-rules.rst. I could be totally wrong, and if so, please respond to <stable(a)vger.kernel.org> and let me know why this patch should be applied. Otherwise, it is now dropped from my patch queues, never to be seen again. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 19ec11a2233d24a7811836fa735203aaccf95a23 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski <bgolaszewski(a)baylibre.com> Date: Thu, 11 Jul 2019 10:29:35 +0200 Subject: [PATCH] gpio: em: remove the gpiochip before removing the irq domain In commit 8764c4ca5049 ("gpio: em: use the managed version of gpiochip_add_data()") we implicitly altered the ordering of resource freeing: since gpiochip_remove() calls gpiochip_irqchip_remove() internally, we now can potentially use the irq_domain after it was destroyed in the remove() callback (as devm resources are freed after remove() has returned).

[V1] mpt3sas: Use 63-bit DMA addressing on SAS35 HBA

by Suganath Prabu

Although SAS3 & SAS3.5 IT HBA controllers support 64-bit DMA addressing, as per hardware design, DMA address with all 64-bits set (0xFFFFFFFF-FFFFFFFF) results in a firmware fault. Fix: Driver will set 63-bit DMA mask to ensure the above address will not be used.

[PATCH] iommu: arm-smmu-v3: Mark expected switch fall-through

by Anders Roxell

When fall-through warnings was enabled by default, commit d93512ef0f0e ("Makefile: Globally enable fall-through warning"), the following warning was starting to show up: ../drivers/iommu/arm-smmu-v3.c: In function ‘arm_smmu_write_strtab_ent’: ../drivers/iommu/arm-smmu-v3.c:1189:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if (disable_bypass) ^ ../drivers/iommu/arm-smmu-v3.c:1191:3: note: here default: ^~~~~~~ Rework so that the compiler doesn't warn about fall-through. Make it clearer by calling 'BUG()' when disable_bypass is set, and always 'break;' Cc: stable(a)vger.kernel.org # v4.2+ Fixes: 5bc0a11664e1 ("iommu/arm-smmu: Don't BUG() if we find aborting STEs with disable_bypass") Signed-off-by: Anders Roxell <anders.roxell(a)linaro.org> --- drivers/iommu/arm-smmu-v3.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/drivers/iommu/arm-smmu-v3.c b/drivers/iommu/arm-smmu-v3.c index a9a9fabd3968..8e5f0565996d 100644 --- a/drivers/iommu/arm-smmu-v3.c +++ b/drivers/iommu/arm-smmu-v3.c @@ -1186,8 +1186,9 @@ static void arm_smmu_write_strtab_ent(struct arm_smmu_master *master, u32 sid, ste_live = true; break; case STRTAB_STE_0_CFG_ABORT: - if (disable_bypass) - break; + if (!disable_bypass) + BUG(); + break; default: BUG(); /* STE corruption */ } -- 2.20.1

FAILED: patch "[PATCH] vxlan: do not destroy fdb if register_netdevice() is failed" failed to apply to 4.19-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.19-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 7c31e54aeee517d1318dfc0bde9fa7de75893dc6 Mon Sep 17 00:00:00 2001 From: Taehee Yoo <ap420073(a)gmail.com> Date: Fri, 28 Jun 2019 14:07:25 +0900 Subject: [PATCH] vxlan: do not destroy fdb if register_netdevice() is failed __vxlan_dev_create() destroys FDB using specific pointer which indicates a fdb when error occurs. But that pointer should not be used when register_netdevice() fails because register_netdevice() internally destroys fdb when error occurs. This patch makes vxlan_fdb_create() to do not link fdb entry to vxlan dev internally. Instead, a new function vxlan_fdb_insert() is added to link fdb to vxlan dev. vxlan_fdb_insert() is called after calling register_netdevice(). This routine can avoid situation that ->ndo_uninit() destroys fdb entry in error path of register_netdevice(). Hence, error path of __vxlan_dev_create() routine can have an opportunity to destroy default fdb entry by hand.

[PATCH 10/27] drm/i915: Flush extra hard after writing relocations through the GTT

by Chris Wilson

Recently discovered in commit bdae33b8b82b ("drm/i915: Use maximum write flush for pwrite_gtt") was that we needed to our full write barrier before changing the GGTT PTE to ensure that our indirect writes through the GTT landed before the PTE changed (and the writes end up in a different page). That also applies to our GGTT relocation path.

[PATCH 2/2] drm/nouveau: Don't retry infinitely when receiving no data on i2c over AUX

by Lyude Paul

While I had thought I had fixed this issue in: commit 342406e4fbba ("drm/nouveau/i2c: Disable i2c bus access after ->fini()") It turns out that while I did fix the error messages I was seeing on my P50 when trying to access i2c busses with the GPU in runtime suspend, I accidentally had missed one important detail that was mentioned on the bug report this commit was supposed to fix: that the CPU would only lock up when trying to access i2c busses _on connected devices_ _while the GPU is not in runtime suspend_. Whoops. That definitely explains why I was not able to get my machine to hang with i2c bus interactions until now, as plugging my P50 into it's dock with an HDMI monitor connected allowed me to finally reproduce this locally. Now that I have managed to reproduce this issue properly, it looks like the problem is much simpler then it looks. It turns out that some connected devices, such as MST laptop docks, will actually ACK i2c reads even if no data was actually read: [ 275.063043] nouveau 0000:01:00.0: i2c: aux 000a: 1: 0000004c 1 [ 275.063447] nouveau 0000:01:00.0: i2c: aux 000a: 00 01101000 10040000 [ 275.063759] nouveau 0000:01:00.0: i2c: aux 000a: rd 00000001 [ 275.064024] nouveau 0000:01:00.0: i2c: aux 000a: rd 00000000 [ 275.064285] nouveau 0000:01:00.0: i2c: aux 000a: rd 00000000 [ 275.064594] nouveau 0000:01:00.0: i2c: aux 000a: rd 00000000 Because we don't handle the situation of i2c ack without any data, we end up entering an infinite loop in nvkm_i2c_aux_i2c_xfer() since the value of cnt always remains at 0. This finally properly explains how this could result in a CPU hang like the ones observed in the aforementioned commit. So, fix this by retrying transactions if no data is written or received, and give up and fail the transaction if we continue to not write or receive any data after 32 retries.

Later on, when the spapr XIVE init code handles xive=off, it disables XIVE and tries to fall back on the legacy mode XICS. This discrepency causes a kernel panic because the hypervisor is configured to provide the XIVE interrupt mode to the guest : kernel BUG at arch/powerpc/sysdev/xics/xics-common.c:135! ...

One exception though: if the host only supports XIVE, we still want to boot so we ignore xive=off. Similarly, have the spapr XIVE init code to looking at the interrupt mode negotiated during CAS, and ignore xive=off if the hypervisor only supports XIVE.

[PATCH] PCI: set BAR size bits correctly in Resize BAR control register

by Sumit Saxena

In Resize BAR control register, bits[8:12] represents size of BAR. As per PCIe specification, below is encoded values in register bits to actual BAR size table: Bits BAR size 0 1 MB 1 2 MB 2 4 MB 3 8 MB -- For 1 MB BAR size, BAR size bits should be set to 0 but incorrectly these bits are set to "1f". Latest megaraid_sas and mpt3sas adapters which support Resizable BAR with 1 MB BAR size fails to initialize during system resume from S3 sleep. Fix: Correctly set BAR size bits to "0" for 1MB BAR size.

When testing our MPTCP out-of-tree kernel[1] with KASAN last week-end, we saw some new warnings, always the same trace and looking like that: [ 16.464577] ================================================================== [ 16.465448] BUG: KASAN: slab-out-of-bounds in strscpy+0x49d/0x590 [ 16.466171] Read of size 8 at addr ffff88803525f788 by task confd/330 [ 16.467114] [ 16.467313] CPU: 0 PID: 330 Comm: confd Not tainted 4.14.133-mptcp+ #2 [ 16.468071] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 0.5.1 01/01/2011 [ 16.469016] Call Trace: [ 16.469318] dump_stack+0xa6/0x12e [ 16.469721] ? _atomic_dec_and_lock+0x1b2/0x1b2 [ 16.470255] ? radix_tree_lookup+0x10/0x10 [ 16.470764] ? strscpy+0x49d/0x590 [ 16.471299] print_address_description+0xa1/0x330 [ 16.471918] ? strscpy+0x49d/0x590 [ 16.472321] kasan_report+0x23f/0x350 [ 16.472751] strscpy+0x49d/0x590 [ 16.473135] ? strncpy+0xd0/0xd0 [ 16.473518] p9dirent_read+0x26b/0x510 [ 16.473977] ? unwind_next_frame+0xc97/0x1eb0 [ 16.474481] ? p9stat_read+0x440/0x440 [ 16.474945] ? entry_SYSCALL_64_after_hwframe+0x3d/0xa2 [ 16.475543] ? rcutorture_record_progress+0x10/0x10 [ 16.476123] ? kernel_text_address+0x111/0x120 [ 16.476656] ? __kernel_text_address+0xe/0x30 [ 16.477273] v9fs_dir_readdir_dotl+0x340/0x5b0 [ 16.477900] ? kasan_slab_free+0x12d/0x1a0 [ 16.478377] ? v9fs_dir_readdir+0x810/0x810 [ 16.478887] ? new_slab+0x29f/0x3b0 [ 16.479298] ? iterate_fd+0x300/0x300 [ 16.479728] ? do_filp_open+0x24a/0x3b0 [ 16.480177] ?

In this change backported by Sasha, strcpy() has been replaced by strscpy(). This is known to cause KASAN false-positives, see: 1a3241ff10d0 (lib/strscpy: Shut up KASAN false-positives in strscpy()). Note that this commit depends on the two parent ones. Could it then be possible to also backport these three commits please? The three commits apply without any issues. I followed the documention to propose these three commits to stable, the Option 3.

[PATCH] xhci: Fix crash if scatter gather is used with Immediate Data Transfer (IDT).

by Mathias Nyman

A second regression was found in the immediate data transfer (IDT) support which was added to 5.2 kernel IDT is used to transfer small amounts of data (up to 8 bytes) in the field normally used for data dma address, thus avoiding dma mapping. If the data was not already dma mapped, then IDT support assumed data was in urb->transfer_buffer, and did not take into accound that even small amounts of data (8 bytes) can be in a scatterlist instead. This caused a NULL pointer dereference when sg_dma_len() was used with non-dma mapped data. Solve this by not using IDT if scatter gather buffer list is used.

The logic in usb_amd_find_chipset_info currently checks for unaffected chipsets rather than affected ones. This broke once a new chipset was added in e788787ef. It makes more sense to reverse the logic so it won't need to be updated as new chipsets are added. Note that the core of the workaround in usb_amd_quirk_pll does correctly check the chipset.

[PATCH] media: vivid: fix device init when no_error_inj=1 and fb disabled

by Guillaume Tucker

Add an extra condition to add the video output control class when the device has some hdmi outputs defined. This is required to then always be able to add the display present control, which is enabled when there are some hdmi outputs. This fixes the corner case where no_error_inj is enabled and the device has no frame buffer but some hdmi outputs, as otherwise the video output control class would be added anyway. Without this fix, the sanity checks fail in v4l2_ctrl_new() as name is NULL.

[PATCH] sd_zbc: Fix report zones buffer allocation

by Damien Le Moal

commit b091ac616846a1da75b1f2566b41255ce7f0e0a6 upstream. During disk scan and revalidation done with sd_revalidate(), the zones of a zoned disk are checked using the helper function blk_revalidate_disk_zones() if a configuration change is detected (change in the number of zones or zone size). The function blk_revalidate_disk_zones() issues report_zones calls that are very large, that is, to obtain zone information for all zones of the disk with a single command. The size of the report zones command buffer necessary for such large request generally is lower than the disk max_hw_sectors and KMALLOC_MAX_SIZE (4MB) and succeeds on boot (no memory fragmentation), but often fail at run time (e.g. hot-plug event). This causes the disk revalidation to fail and the disk capacity to be changed to 0. This problem can be avoided by using vmalloc() instead of kmalloc() for the buffer allocation. To limit the amount of memory to be allocated, this patch also introduces the arbitrary SD_ZBC_REPORT_MAX_ZONES maximum number of zones to report with a single report zones command. This limit may be lowered further to satisfy the disk max_hw_sectors limit.

The function blk_revalidate_disk_zones() issues report_zones calls that are very large, that is, to obtain zone information for all zones of the disk with a single command. The size of the report zones command buffer necessary for such large request generally is lower than the disk max_hw_sectors and KMALLOC_MAX_SIZE (4MB) and succeeds on boot (no memory fragmentation), but often fail at run time (e.g. hot-plug event). This causes the disk revalidation to fail and the disk capacity to be changed to 0. This problem can be avoided by using vmalloc() instead of kmalloc() for the buffer allocation. To limit the amount of memory to be allocated, this patch also introduces the arbitrary SD_ZBC_REPORT_MAX_ZONES maximum number of zones to report with a single report zones command. This limit may be lowered further to satisfy the disk max_hw_sectors limit. Finally, to ensure that the vmalloc-ed buffer can always be mapped in a request, the buffer size is further limited to at most queue_max_segments() pages, allowing successful mapping of the buffer even in the worst case scenario where none of the buffer pages are contiguous.

[PATCH] block: Limit zone array allocation size

by Damien Le Moal

From: "gregkh(a)linuxfoundation.org" <gregkh(a)linuxfoundation.org> commit 26202928fafad8bda8b478edb7e62c885be623d7 upstream. Limit the size of the struct blk_zone array used in blk_revalidate_disk_zones() to avoid memory allocation failures leading to disk revalidation failure.

[PATCH 4.9 1/2] um: Allow building and running on older hosts

by Alessio Balsini

commit 0a987645672ebde7844a9c0732a5a25f3d4bb6c6 upstream. Commit a78ff1112263 ("um: add extended processor state save/restore support") and b6024b21fec8 ("um: extend fpstate to _xstate to support YMM registers") forced the use of the x86 FP _xstate and PTRACE_GETREGSET/SETREGSET. On older hosts, we would neither be able to build UML nor run it anymore with these two commits applied because we don't have definitions for struct _xstate nor these two ptrace requests. We can determine at build time which fp context structure to check against, just like we can keep using the old i387 fp save/restore if PTRACE_GETRESET/SETREGSET are not defined.

To avoid using the uninitialized struct page, immediately return with KPF_RESERVED at the beginning of stable_page_flags() if the page is reserved by ZONE_DEVICE driver.

[to-be-updated] mm-document-zone-device-struct-page-field-usage.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm: document zone device struct page field usage has been removed from the -mm tree. Its filename was mm-document-zone-device-struct-page-field-usage.patch This patch was dropped because an updated version will be merged ------------------------------------------------------ From: Ralph Campbell <rcampbell(a)nvidia.com> Subject: mm: document zone device struct page field usage Patch series "mm/hmm: fixes for device private page migration", v2. Testing the latest linux git tree turned up a few bugs with page migration to and from ZONE_DEVICE private and anonymous pages. Hopefully it clarifies how ZONE_DEVICE private struct page uses the same mapping and index fields from the source anonymous page mapping. This patch (of 3): Struct page for ZONE_DEVICE private pages uses the page->mapping and and page->index fields while the source anonymous pages are migrated to device private memory. This is so rmap_walk() can find the page when migrating the ZONE_DEVICE private page back to system memory. ZONE_DEVICE pmem backed fsdax pages also use the page->mapping and page->index fields when files are mapped into a process address space. Restructure struct page and add comments to make this more clear.

[PATCH v3 1/2] x86/purgatory: do not use __builtin_memcpy and __builtin_memset

by Nick Desaulniers

Implementing memcpy and memset in terms of __builtin_memcpy and __builtin_memset is problematic. GCC at -O2 will replace calls to the builtins with calls to memcpy and memset (but will generate an inline implementation at -Os). Clang will replace the builtins with these calls regardless of optimization level. $ llvm-objdump -dr arch/x86/purgatory/string.o | tail 0000000000000339 memcpy: 339: 48 b8 00 00 00 00 00 00 00 00 movabsq $0, %rax 000000000000033b: R_X86_64_64 memcpy 343: ff e0 jmpq *%rax 0000000000000345 memset: 345: 48 b8 00 00 00 00 00 00 00 00 movabsq $0, %rax 0000000000000347: R_X86_64_64 memset 34f: ff e0 Such code results in infinite recursion at runtime. This is observed when doing kexec. Instead, reuse an implementation from arch/x86/boot/compressed/string.c if we define warn as a symbol. Also, Clang may lower memcmp's that compare against 0 to bcmp's, so add a small definition, too.

[PATCH v3 3/3] mm/hmm: Fix bad subpage pointer in try_to_unmap_one

by Ralph Campbell

When migrating an anonymous private page to a ZONE_DEVICE private page, the source page->mapping and page->index fields are copied to the destination ZONE_DEVICE struct page and the page_mapcount() is increased. This is so rmap_walk() can be used to unmap and migrate the page back to system memory. However, try_to_unmap_one() computes the subpage pointer from a swap pte which computes an invalid page pointer and a kernel panic results such as: BUG: unable to handle page fault for address: ffffea1fffffffc8 Currently, only single pages can be migrated to device private memory so no subpage computation is needed and it can be set to "page". Fixes: a5430dda8a3a1c ("mm/migrate: support un-addressable ZONE_DEVICE page in migration") Signed-off-by: Ralph Campbell <rcampbell(a)nvidia.com> Cc: "Jérôme Glisse" <jglisse(a)redhat.com> Cc: "Kirill A.

The first part run() does the jobs that do not require the md threads. The second part start() does the jobs that require the md threads. Now it just does run() in adding new journal device. It needs to do the second part start() too.

[PATCH V3 0/2] block/scsi/dm-rq: fix leak of request private data in dm-mpath

by Ming Lei

Hi, When one request is dispatched to LLD via dm-rq, if the result is BLK_STS_*RESOURCE, dm-rq will free the request. However, LLD may allocate private data for this request, so this way will cause memory leak. Add .cleanup_rq() callback and implement it in SCSI for fixing the issue, since SCSI is the only driver which allocates private requst data in .queue_rq() path. Another use case of this callback is to free the request and re-submit bios during cpu hotplug when the hctx is dead, see the following link: https://lore.kernel.org/linux-block/f122e8f2-5ede-2d83-9ca0-bc713ce66d01@hu… V3: - run .cleanup_rq() from dm-rq because this issue is dm-rq specific, and even in future it should be still very unusual to free request in this way. If we call .cleanup_rq() in generic rq free code(fast path), cost will be introduced unnecessarily, also we have to consider related race. V2: - run .cleanup_rq() in blk_mq_free_request(), as suggested by Mike Ming Lei (2): blk-mq: add callback of .cleanup_rq scsi: implement .cleanup_rq callback drivers/md/dm-rq.c | 1 + drivers/scsi/scsi_lib.c | 13 +++++++++++++ include/linux/blk-mq.h | 13 +++++++++++++ 3 files changed, 27 insertions(+) Cc: Ewan D.

If the transfer buffer in the URB is already DMA mapped then IDT should not be used. urb->transfer_dma will already contain a valid dma address, and there is no guarantee the data in urb->transfer_buffer is valid. The IDT support patch used urb->transfer_dma as a temporary storage, copying data from urb->transfer_buffer into it. Issue was solved by preventing IDT if transfer buffer is already dma mapped, and by not using urb->transfer_dma as temporary storage.

The size of the report zones command buffer necessary for such large request generally is lower than the disk max_hw_sectors and KMALLOC_MAX_SIZE (4MB) and succeeds on boot (no memory fragmentation), but often fail at run time (e.g. hot-plug event). This causes the disk revalidation to fail and the disk capacity to be changed to 0. This problem can be avoided by using vmalloc() instead of kmalloc() for the buffer allocation. To limit the amount of memory to be allocated, this patch also introduces the arbitrary SD_ZBC_REPORT_MAX_ZONES maximum number of zones to report with a single report zones command. This limit may be lowered further to satisfy the disk max_hw_sectors limit. Finally, to ensure that the vmalloc-ed buffer can always be mapped in a request, the buffer size is further limited to at most queue_max_segments() pages, allowing successful mapping of the buffer even in the worst case scenario where none of the buffer pages are contiguous.

[PATCH 2/7] can: rcar_canfd: fix possible IRQ storm on high load

by Marc Kleine-Budde

From: Nikita Yushchenko <nikita.yoush(a)cogentembedded.com> We have observed rcar_canfd driver entering IRQ storm under high load, with following scenario: - rcar_canfd_global_interrupt() in entered due to Rx available, - napi_schedule_prep() is called, and sets NAPIF_STATE_SCHED in state - Rx fifo interrupts are masked, - rcar_canfd_global_interrupt() is entered again, this time due to error interrupt (e.g. due to overflow), - since scheduled napi poller has not yet executed, condition for calling napi_schedule_prep() from rcar_canfd_global_interrupt() remains true, thus napi_schedule_prep() gets called and sets NAPIF_STATE_MISSED flag in state, - later, napi poller function rcar_canfd_rx_poll() gets executed, and calls napi_complete_done(), - due to NAPIF_STATE_MISSED flag in state, this call does not clear NAPIF_STATE_SCHED flag from state, - on return from napi_complete_done(), rcar_canfd_rx_poll() unmasks Rx interrutps, - Rx interrupt happens, rcar_canfd_global_interrupt() gets called and calls napi_schedule_prep(), - since NAPIF_STATE_SCHED is set in state at this time, this call returns false, - due to that false return, rcar_canfd_global_interrupt() returns without masking Rx interrupt - and this results into IRQ storm: unmasked Rx interrupt happens again and again is misprocessed in the same way. This patch fixes that scenario by unmasking Rx interrupts only when napi_complete_done() returns true, which means it has cleared NAPIF_STATE_SCHED in state.

[PATCH 4.9] crypto: caam - limit output IV to CBC to work around CTR mode DMA issue

by Horia Geantă

From: Ard Biesheuvel <ard.biesheuvel(a)linaro.org> commit ed527b13d800dd515a9e6c582f0a73eca65b2e1b upstream. The CAAM driver currently violates an undocumented and slightly controversial requirement imposed by the crypto stack that a buffer referred to by the request structure via its virtual address may not be modified while any scatterlists passed via the same request structure are mapped for inbound DMA. This may result in errors like alg: aead: decryption failed on test 1 for gcm_base(ctr-aes-caam,ghash-generic): ret=74 alg: aead: Failed to load transform for gcm(aes): -2 on non-cache coherent systems, due to the fact that the GCM driver passes an IV buffer by virtual address which shares a cacheline with the auth_tag buffer passed via a scatterlist, resulting in corruption of the auth_tag when the IV is updated while the DMA mapping is live. Since the IV that is returned to the caller is only valid for CBC mode, and given that the in-kernel users of CBC (such as CTS) don't trigger the same issue as the GCM driver, let's just disable the output IV generation for all modes except CBC for the time being.

[PATCH] coda: pass the host file in vma->vm_file on mmap

by Jan Harkes

commit 7fa0a1da3dadfd9216df7745a1331fdaa0940d1c upstream. Various file systems expect that vma->vm_file points at their own file handle, several use file_inode(vma->vm_file) to get at their inode or use vma->vm_file->private_data. However the way Coda wrapped mmap on a host file broke this assumption, vm_file was still pointing at the Coda file and the host file systems would scribble over Coda's inode and private file data. This patch fixes the incorrect expectation and wraps vm_ops->open and vm_ops->close to allow Coda to track when the vm_area_struct is destroyed so we still release the reference on the Coda file handle at the right time. This patch differs from the original upstream patch because older stable kernels do not have the call_mmap vfs helper so we call f_ops->mmap directly.

patch "binder: prevent transactions to context manager from its own process." added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled binder: prevent transactions to context manager from its own process. to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 49ed96943a8e0c62cc5a9b0a6cfc88be87d1fcec Mon Sep 17 00:00:00 2001 From: Hridya Valsaraju <hridya(a)google.com> Date: Mon, 15 Jul 2019 12:18:04 -0700 Subject: binder: prevent transactions to context manager from its own process. Currently, a transaction to context manager from its own process is prevented by checking if its binder_proc struct is the same as that of the sender. However, this would not catch cases where the process opens the binder device again and uses the new fd to send a transaction to the context manager.

[PATCH AUTOSEL 5.2 001/249] ath10k: Check tx_stats before use it

by Sasha Levin

From: Yingying Tang <yintang(a)codeaurora.org> [ Upstream commit 9e7251fa38978b85108c44743e1436d48e8d0d76 ] tx_stats will be freed and set to NULL before debugfs_sta node is removed in station disconnetion process. So if read the debugfs_sta node there may be NULL pointer error. Add check for tx_stats before use it to resove this issue.

[PATCH 0/9] xfs: stable fixes for v4.19.y - circa ~ v4.19.58

by Luis Chamberlain

"Oyez Oyez..." its time for a stable update of fixes for XFS. 4 out of the 9 fixes here were recommended by Amir, and tested by both Amir and Sasha. I've found a few other fixes, and have tested all these changes with fstests against the following configurations in fstests sections as per oscheck [0] and found no regressions in comparsin to v4.19.58 and by running the full set of tests 3 times completely: * xfs * xfs_nocrc * xfs_nocrc_512 * xfs_reflink * xfs_reflink_1024 * xfs_logdev * xfs_realtimedev Known issues are listed on the expunges files, but its no different than the current baseline. Worth noting is a now known generic/388 crash on xfs_nocrc, xfs_reflink, and what may be a new section we should consider to track: "xfs_reflink_normapbt" with the following resulting filesystem: # xfs_info /dev/loop5 meta-data=/dev/loop5 isize=512 agcount=4, agsize=1310720 blks = sectsz=512 attr=2, projid32bit=1 = crc=1 finobt=1, sparse=1, rmapbt=0 = reflink=1 data = bsize=4096 blocks=5242880, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0, ftype=1 log =internal log bsize=4096 blocks=2560, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 Do we want to create a baseline and track this configuration for stable as well? There is a stable bug tracking this, kz#204223 [1], and a respective bug also present on upstream via kz#204049 [2] which Zorro reported. But, again, nothing changes from the baseline. I'd appreciate further reviews from the patches. I have some other fixes in mind as well, but I'd rather not delay this set and think this is a first good batch. This also goes out as the first set of stable fixes using oscheck's new devops infrastructure built on ansible / vagrant / terraform [3]. For this release I've used vagrant with KVM, perhaps the next one I'll try terraform on whatever cloud solution someone is willing to let me use. You can also find these changes on my 20190718-linux-xfs-4.19.y-v1 branch on kernel.org [4]. Lemme know if you see any issues or have any questions.

+ cgroup-kselftest-relax-fs_spec-checks.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: cgroup: kselftest: relax fs_spec checks has been added to the -mm tree. Its filename is cgroup-kselftest-relax-fs_spec-checks.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/cgroup-kselftest-relax-fs_spec-che… and later at http://ozlabs.org/~akpm/mmotm/broken-out/cgroup-kselftest-relax-fs_spec-che… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Chris Down <chris(a)chrisdown.name> Subject: cgroup: kselftest: relax fs_spec checks On my laptop most memcg kselftests were being skipped because it claimed cgroup v2 hierarchy wasn't mounted, but this isn't correct. Instead, it seems current systemd HEAD mounts it with the name "cgroup2" instead of "cgroup": % grep cgroup /proc/mounts cgroup2 /sys/fs/cgroup cgroup2 rw,nosuid,nodev,noexec,relatime,nsdelegate 0 0 I can't think of a reason to need to check fs_spec explicitly since it's arbitrary, so we can just rely on fs_vfstype. After these changes, `make TARGETS=cgroup kselftest` actually runs the cgroup v2 tests in more cases.

[PATCH 05/23] drm/i915: Flush extra hard after writing relocations through the GTT

by Chris Wilson

Recently discovered in commit bdae33b8b82b ("drm/i915: Use maximum write flush for pwrite_gtt") was that we needed to our full write barrier before changing the GGTT PTE to ensure that our indirect writes through the GTT landed before the PTE changed (and the writes end up in a different page). That also applies to our GGTT relocation path.

[PATCH 4.14, 4.19] crypto: caam - limit output IV to CBC to work around CTR mode DMA issue

by Horia Geantă

From: Ard Biesheuvel <ard.biesheuvel(a)linaro.org> commit ed527b13d800dd515a9e6c582f0a73eca65b2e1b upstream. The CAAM driver currently violates an undocumented and slightly controversial requirement imposed by the crypto stack that a buffer referred to by the request structure via its virtual address may not be modified while any scatterlists passed via the same request structure are mapped for inbound DMA. This may result in errors like alg: aead: decryption failed on test 1 for gcm_base(ctr-aes-caam,ghash-generic): ret=74 alg: aead: Failed to load transform for gcm(aes): -2 on non-cache coherent systems, due to the fact that the GCM driver passes an IV buffer by virtual address which shares a cacheline with the auth_tag buffer passed via a scatterlist, resulting in corruption of the auth_tag when the IV is updated while the DMA mapping is live. Since the IV that is returned to the caller is only valid for CBC mode, and given that the in-kernel users of CBC (such as CTS) don't trigger the same issue as the GCM driver, let's just disable the output IV generation for all modes except CBC for the time being.

This is generally fine and avoids future attempts to log it from having to do repeated work that brings no value. However, if we write data to a file, then evict its inode after all the dealloc was flushed (and ordered extents completed), rename the file and fsync it, we end up not logging the new extents, since the rename may result in logging that the inode exists in case the parent directory was logged before. The following reproducer shows and explains how this can happen: $ mkfs.btrfs -f /dev/sdb $ mount /dev/sdb /mnt $ mkdir /mnt/dir $ touch /mnt/dir/foo $ touch /mnt/dir/bar # Do a direct IO write instead of a buffered write because with a # buffered write we would need to make sure dealloc gets flushed and # complete before we do the inode eviction later, and we can not do that # from user space with call to things such as sync(2) since that results # in a transaction commit as well. $ xfs_io -d -c "pwrite -S 0xd3 0 4K" /mnt/dir/bar # Keep the directory dir in use while we evict inodes. We want our file # bar's inode to be evicted but we don't want our directory's inode to # be evicted (if it were evicted too, we would not be able to reproduce # the issue since the first fsync below, of file foo, would result in a # transaction commit. $ ( cd /mnt/dir; while true; do :; done ) & $ pid=$! # Wait a bit to give time for the background process to chdir. $ sleep 0.1 # Evict all inodes, except the inode for the directory dir because it is # currently in use by our background process. $ echo 2 > /proc/sys/vm/drop_caches # fsync file foo, which ends up persisting information about the parent # directory because it is a new inode. $ xfs_io -c fsync /mnt/dir/foo # Rename bar, this results in logging that this inode exists (inode item, # names, xattrs) because the parent directory is in the log. $ mv /mnt/dir/bar /mnt/dir/baz # Now fsync baz, which ends up doing absolutely nothing because of the # rename operation which logged that the inode exists only. $ xfs_io -c fsync /mnt/dir/baz <power failure> $ mount /dev/sdb /mnt $ od -t x1 -A d /mnt/dir/baz 0000000 --> Empty file, data we wrote is missing.

This is generally fine and avoids future attempts to log it from having to do repeated work that brings no value. However, if we write data to a file, then evict its inode after all the dealloc was flushed (and ordered extents completed), rename the file and fsync it, we end up not logging the new extents, since the rename may result in logging that the inode exists in case the parent directory was logged before. The following reproducer shows and explains how this can happen: $ mkfs.btrfs -f /dev/sdb $ mount /dev/sdb /mnt $ mkdir /mnt/dir $ touch /mnt/dir/foo $ touch /mnt/dir/bar # Do a direct IO write instead of a buffered write because with a # buffered write we would need to make sure dealloc gets flushed and # complete before we do the inode eviction later, and we can not do that # from user space with call to things such as sync(2) since that results # in a transaction commit as well. $ xfs_io -d -c "pwrite -S 0xd3 0 4K" /mnt/dir/bar # Keep the directory dir in use while we evict inodes. We want our file # bar's inode to be evicted but we don't want our directory's inode to # be evicted (if it were evicted too, we would not be able to reproduce # the issue since the first fsync below, of file foo, would result in a # transaction commit. $ ( cd /mnt/dir; while true; do :; done ) & $ pid=$! # Wait a bit to give time for the background process to chdir. $ sleep 0.1 # Evict all inodes, except the inode for the directory dir because it is # currently in use by our background process. $ echo 2 > /proc/sys/vm/drop_caches # fsync file foo, which ends up persisting information about the parent # directory because it is a new inode. $ xfs_io -c fsync /mnt/dir/foo # Rename bar, this results in logging that this inode exists (inode item, # names, xattrs) because the parent directory is in the log. $ mv /mnt/dir/bar /mnt/dir/baz # Now fsync baz, which ends up doing absolutely nothing because of the # rename operation which logged that the inode exists only. $ xfs_io -c fsync /mnt/dir/baz <power failure> $ mount /dev/sdb /mnt $ od -t x1 -A d /mnt/dir/baz 0000000 --> Empty file, data we wrote is missing. Fix this by not updating last_sub_trans of an inode when we are logging only that it exists and the inode was not yet logged since it was loaded from disk (full_sync bit set), this is enough to make btrfs_inode_in_log() return false for this scenario and make us log the inode.

[PATCH 4.19] kconfig: fix missing choice values in auto.conf

by Masahiro Yamada

commit 8e2442a5f86e1f77b86401fce274a7f622740bc4 upstream. Since commit 00c864f8903d ("kconfig: allow all config targets to write auto.conf if missing"), Kconfig creates include/config/auto.conf in the defconfig stage when it is missing. Joonas Kylmälä reported incorrect auto.conf generation under some circumstances. To reproduce it, apply the following diff: | --- a/arch/arm/configs/imx_v6_v7_defconfig | +++ b/arch/arm/configs/imx_v6_v7_defconfig | @@ -345,14 +345,7 @@ CONFIG_USB_CONFIGFS_F_MIDI=y | CONFIG_USB_CONFIGFS_F_HID=y | CONFIG_USB_CONFIGFS_F_UVC=y | CONFIG_USB_CONFIGFS_F_PRINTER=y | -CONFIG_USB_ZERO=m | -CONFIG_USB_AUDIO=m | -CONFIG_USB_ETH=m | -CONFIG_USB_G_NCM=m | -CONFIG_USB_GADGETFS=m | -CONFIG_USB_FUNCTIONFS=m | -CONFIG_USB_MASS_STORAGE=m | -CONFIG_USB_G_SERIAL=m | +CONFIG_USB_FUNCTIONFS=y | CONFIG_MMC=y | CONFIG_MMC_SDHCI=y | CONFIG_MMC_SDHCI_PLTFM=y And then, run: $ make ARCH=arm mrproper imx_v6_v7_defconfig You will see CONFIG_USB_FUNCTIONFS=y is correctly contained in the .config, but not in the auto.conf. Please note drivers/usb/gadget/legacy/Kconfig is included from a choice block in drivers/usb/gadget/Kconfig. So USB_FUNCTIONFS is a choice value. This is probably a similar situation described in commit beaaddb62540 ("kconfig: tests: test defconfig when two choices interact"). When sym_calc_choice() is called, the choice symbol forgets the SYMBOL_DEF_USER unless all of its choice values are explicitly set by the user. The choice symbol is given just one chance to recall it because set_all_choice_values() is called if SYMBOL_NEED_SET_CHOICE_VALUES is set. When sym_calc_choice() is called again, the choice symbol forgets it forever, since SYMBOL_NEED_SET_CHOICE_VALUES is a one-time aid. Hence, we cannot call sym_clear_all_valid() again and again. It is crazy to repeat set and unset of internal flags. However, we cannot simply get rid of "sym->flags &= flags | ~SYMBOL_DEF_USER;" Doing so would re-introduce the problem solved by commit 5d09598d488f ("kconfig: fix new choices being skipped upon config update"). To work around the issue, conf_write_autoconf() stopped calling sym_clear_all_valid(). conf_write() must be changed accordingly. Currently, it clears SYMBOL_WRITE after the symbol is written into the .config file. This is needed to prevent it from writing the same symbol multiple times in case the symbol is declared in two or more locations. I added the new flag SYMBOL_WRITTEN, to track the symbols that have been written. Anyway, this is a cheesy workaround in order to suppress the issue as far as defconfig is concerned. Handling of choices is totally broken. sym_clear_all_valid() is called every time a user touches a symbol from the GUI interface. To reproduce it, just add a new symbol drivers/usb/gadget/legacy/Kconfig, then touch around unrelated symbols from menuconfig. USB_FUNCTIONFS will disappear from the .config file. I added the Fixes tag since it is more fatal than before. But, this has been broken since long long time before, and still it is. We should take a closer look to fix this correctly somehow.

Biederman" <ebiederm(a)xmission.com> Date: Wed, 15 May 2019 22:54:56 -0500 Subject: [PATCH] signal: Correct namespace fixups of si_pid and si_uid The function send_signal was split from __send_signal so that it would be possible to bypass the namespace logic based upon current[1]. As it turns out the si_pid and the si_uid fixup are both inappropriate in the case of kill_pid_usb_asyncio so move that logic into send_signal. It is difficult to arrange but possible for a signal with an si_code of SI_TIMER or SI_SIGIO to be sent across namespace boundaries. In which case tests for when it is ok to change si_pid and si_uid based on SI_FROMUSER are incorrect. Replace the use of SI_FROMUSER with a new test has_si_pid_and_used based on siginfo_layout. Now that the uid fixup is no longer present after expanding SEND_SIG_NOINFO properly calculate the si_uid that the target task needs to read.

The patch below does not apply to the 4.4-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 70f1b0d34bdf03065fe869e93cc17cad1ea20c4a Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" <ebiederm(a)xmission.com> Date: Thu, 7 Feb 2019 19:44:12 -0600 Subject: [PATCH] signal/usb: Replace kill_pid_info_as_cred with kill_pid_usb_asyncio The usb support for asyncio encoded one of it's values in the wrong field. It should have used si_value but instead used si_addr which is not present in the _rt union member of struct siginfo. The practical result of this is that on a 64bit big endian kernel when delivering a signal to a 32bit process the si_addr field is set to NULL, instead of the expected pointer value. This issue can not be fixed in copy_siginfo_to_user32 as the usb usage of the the _sigfault (aka si_addr) member of the siginfo union when SI_ASYNCIO is set is incompatible with the POSIX and glibc usage of the _rt member of the siginfo union. Therefore replace kill_pid_info_as_cred with kill_pid_usb_asyncio a dedicated function for this one specific case. There are no other users of kill_pid_info_as_cred so this specialization should have no impact on the amount of code in the kernel. Have kill_pid_usb_asyncio take instead of a siginfo_t which is difficult and error prone, 3 arguments, a signal number, an errno value, and an address enconded as a sigval_t. The encoding of the address as a sigval_t allows the code that reads the userspace request for a signal to handle this compat issue along with all of the other compat issues. Add BUILD_BUG_ONs in kernel/signal.c to ensure that we can now place the pointer value at the in si_pid (instead of si_addr). That is the code now verifies that si_pid and si_addr always occur at the same location. Further the code veries that for native structures a value placed in si_pid and spilling into si_uid will appear in userspace in si_addr (on a byte by byte copy of siginfo or a field by field copy of siginfo). The code also verifies that for a 64bit kernel and a 32bit userspace the 32bit pointer will fit in si_pid. I have used the usbsig.c program below written by Alan Stern and slightly tweaked by me to run on a big endian machine to verify the issue exists (on sparc64) and to confirm the patch below fixes the issue. /* usbsig.c -- test USB async signal delivery */ #define _GNU_SOURCE #include <stdio.h> #include <fcntl.h> #include <signal.h> #include <string.h> #include <sys/ioctl.h> #include <unistd.h> #include <endian.h> #include <linux/usb/ch9.h> #include <linux/usbdevice_fs.h> static struct usbdevfs_urb urb; static struct usbdevfs_disconnectsignal ds; static volatile sig_atomic_t done = 0; void urb_handler(int sig, siginfo_t *info , void *ucontext) { printf("Got signal %d, signo %d errno %d code %d addr: %p urb: %p\n", sig, info->si_signo, info->si_errno, info->si_code, info->si_addr, &urb); printf("%s\n", (info->si_addr == &urb) ?

FAILED: patch "[PATCH] signal/usb: Replace kill_pid_info_as_cred with" failed to apply to 4.9-stable tree

The patch below does not apply to the 4.9-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 70f1b0d34bdf03065fe869e93cc17cad1ea20c4a Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" <ebiederm(a)xmission.com> Date: Thu, 7 Feb 2019 19:44:12 -0600 Subject: [PATCH] signal/usb: Replace kill_pid_info_as_cred with kill_pid_usb_asyncio The usb support for asyncio encoded one of it's values in the wrong field. It should have used si_value but instead used si_addr which is not present in the _rt union member of struct siginfo. The practical result of this is that on a 64bit big endian kernel when delivering a signal to a 32bit process the si_addr field is set to NULL, instead of the expected pointer value. This issue can not be fixed in copy_siginfo_to_user32 as the usb usage of the the _sigfault (aka si_addr) member of the siginfo union when SI_ASYNCIO is set is incompatible with the POSIX and glibc usage of the _rt member of the siginfo union. Therefore replace kill_pid_info_as_cred with kill_pid_usb_asyncio a dedicated function for this one specific case. There are no other users of kill_pid_info_as_cred so this specialization should have no impact on the amount of code in the kernel. Have kill_pid_usb_asyncio take instead of a siginfo_t which is difficult and error prone, 3 arguments, a signal number, an errno value, and an address enconded as a sigval_t. The encoding of the address as a sigval_t allows the code that reads the userspace request for a signal to handle this compat issue along with all of the other compat issues. Add BUILD_BUG_ONs in kernel/signal.c to ensure that we can now place the pointer value at the in si_pid (instead of si_addr). That is the code now verifies that si_pid and si_addr always occur at the same location. Further the code veries that for native structures a value placed in si_pid and spilling into si_uid will appear in userspace in si_addr (on a byte by byte copy of siginfo or a field by field copy of siginfo). The code also verifies that for a 64bit kernel and a 32bit userspace the 32bit pointer will fit in si_pid. I have used the usbsig.c program below written by Alan Stern and slightly tweaked by me to run on a big endian machine to verify the issue exists (on sparc64) and to confirm the patch below fixes the issue. /* usbsig.c -- test USB async signal delivery */ #define _GNU_SOURCE #include <stdio.h> #include <fcntl.h> #include <signal.h> #include <string.h> #include <sys/ioctl.h> #include <unistd.h> #include <endian.h> #include <linux/usb/ch9.h> #include <linux/usbdevice_fs.h> static struct usbdevfs_urb urb; static struct usbdevfs_disconnectsignal ds; static volatile sig_atomic_t done = 0; void urb_handler(int sig, siginfo_t *info , void *ucontext) { printf("Got signal %d, signo %d errno %d code %d addr: %p urb: %p\n", sig, info->si_signo, info->si_errno, info->si_code, info->si_addr, &urb); printf("%s\n", (info->si_addr == &urb) ?

Biederman" <ebiederm(a)xmission.com> Date: Thu, 7 Feb 2019 19:44:12 -0600 Subject: [PATCH] signal/usb: Replace kill_pid_info_as_cred with kill_pid_usb_asyncio The usb support for asyncio encoded one of it's values in the wrong field. It should have used si_value but instead used si_addr which is not present in the _rt union member of struct siginfo. The practical result of this is that on a 64bit big endian kernel when delivering a signal to a 32bit process the si_addr field is set to NULL, instead of the expected pointer value. This issue can not be fixed in copy_siginfo_to_user32 as the usb usage of the the _sigfault (aka si_addr) member of the siginfo union when SI_ASYNCIO is set is incompatible with the POSIX and glibc usage of the _rt member of the siginfo union. Therefore replace kill_pid_info_as_cred with kill_pid_usb_asyncio a dedicated function for this one specific case. There are no other users of kill_pid_info_as_cred so this specialization should have no impact on the amount of code in the kernel. Have kill_pid_usb_asyncio take instead of a siginfo_t which is difficult and error prone, 3 arguments, a signal number, an errno value, and an address enconded as a sigval_t. The encoding of the address as a sigval_t allows the code that reads the userspace request for a signal to handle this compat issue along with all of the other compat issues. Add BUILD_BUG_ONs in kernel/signal.c to ensure that we can now place the pointer value at the in si_pid (instead of si_addr). That is the code now verifies that si_pid and si_addr always occur at the same location. Further the code veries that for native structures a value placed in si_pid and spilling into si_uid will appear in userspace in si_addr (on a byte by byte copy of siginfo or a field by field copy of siginfo). The code also verifies that for a 64bit kernel and a 32bit userspace the 32bit pointer will fit in si_pid. I have used the usbsig.c program below written by Alan Stern and slightly tweaked by me to run on a big endian machine to verify the issue exists (on sparc64) and to confirm the patch below fixes the issue. /* usbsig.c -- test USB async signal delivery */ #define _GNU_SOURCE #include <stdio.h> #include <fcntl.h> #include <signal.h> #include <string.h> #include <sys/ioctl.h> #include <unistd.h> #include <endian.h> #include <linux/usb/ch9.h> #include <linux/usbdevice_fs.h> static struct usbdevfs_urb urb; static struct usbdevfs_disconnectsignal ds; static volatile sig_atomic_t done = 0; void urb_handler(int sig, siginfo_t *info , void *ucontext) { printf("Got signal %d, signo %d errno %d code %d addr: %p urb: %p\n", sig, info->si_signo, info->si_errno, info->si_code, info->si_addr, &urb); printf("%s\n", (info->si_addr == &urb) ?

This resulted in local_irq_restore() potentially modifying the value of PMR in undesired location due to the state of PSR.I upon flag saving [1]. In an attempt to solve this issue in a less hackish manner, introduce a bit (GIC_PRIO_IGNORE_PMR) for the PMR values that can represent whether PSR.I is being used to disable interrupts, in which case it takes precedence of the status of interrupt masking via PMR. GIC_PRIO_PSR_I_SET is chosen such that (<pmr_value> | GIC_PRIO_PSR_I_SET) does not mask more interrupts than <pmr_value> as some sections (e.g. arch_cpu_idle(), interrupt acknowledge path) requires PMR not to mask interrupts that could be signaled to the CPU when using only PSR.I.

Per Intel's SDM, a #MC during VM-Entry is handled in one of three ways, depending on when the #MC is recognoized. As it pertains to this bug fix, the third case explicitly states EXIT_REASON_MCE_DURING_VMENTRY is handled like any other VM-Exit during VM-Entry, i.e. sets bit 31 to indicate the VM-Entry failed. If a machine-check event occurs during a VM entry, one of the following occurs: - The machine-check event is handled as if it occurred before the VM entry: ... - The machine-check event is handled after VM entry completes: ... - A VM-entry failure occurs as described in Section 26.7. The basic exit reason is 41, for "VM-entry failure due to machine-check event". Explicitly handle EXIT_REASON_MCE_DURING_VMENTRY as a one-off case in vmx_vcpu_run() instead of binning it into vmx_complete_atomic_exit(). Doing so allows vmx_vcpu_run() to handle VMX_EXIT_REASONS_FAILED_VMENTRY in a sane fashion and also simplifies vmx_complete_atomic_exit() since VMCS.VM_EXIT_INTR_INFO is guaranteed to be fresh.

Joonas Kylmälä reported incorrect auto.conf generation under some circumstances. To reproduce it, apply the following diff: | --- a/arch/arm/configs/imx_v6_v7_defconfig | +++ b/arch/arm/configs/imx_v6_v7_defconfig | @@ -345,14 +345,7 @@ CONFIG_USB_CONFIGFS_F_MIDI=y | CONFIG_USB_CONFIGFS_F_HID=y | CONFIG_USB_CONFIGFS_F_UVC=y | CONFIG_USB_CONFIGFS_F_PRINTER=y | -CONFIG_USB_ZERO=m | -CONFIG_USB_AUDIO=m | -CONFIG_USB_ETH=m | -CONFIG_USB_G_NCM=m | -CONFIG_USB_GADGETFS=m | -CONFIG_USB_FUNCTIONFS=m | -CONFIG_USB_MASS_STORAGE=m | -CONFIG_USB_G_SERIAL=m | +CONFIG_USB_FUNCTIONFS=y | CONFIG_MMC=y | CONFIG_MMC_SDHCI=y | CONFIG_MMC_SDHCI_PLTFM=y And then, run: $ make ARCH=arm mrproper imx_v6_v7_defconfig You will see CONFIG_USB_FUNCTIONFS=y is correctly contained in the .config, but not in the auto.conf. Please note drivers/usb/gadget/legacy/Kconfig is included from a choice block in drivers/usb/gadget/Kconfig. So USB_FUNCTIONFS is a choice value. This is probably a similar situation described in commit beaaddb62540 ("kconfig: tests: test defconfig when two choices interact"). When sym_calc_choice() is called, the choice symbol forgets the SYMBOL_DEF_USER unless all of its choice values are explicitly set by the user. The choice symbol is given just one chance to recall it because set_all_choice_values() is called if SYMBOL_NEED_SET_CHOICE_VALUES is set. When sym_calc_choice() is called again, the choice symbol forgets it forever, since SYMBOL_NEED_SET_CHOICE_VALUES is a one-time aid. Hence, we cannot call sym_clear_all_valid() again and again. It is crazy to repeat set and unset of internal flags. However, we cannot simply get rid of "sym->flags &= flags | ~SYMBOL_DEF_USER;" Doing so would re-introduce the problem solved by commit 5d09598d488f ("kconfig: fix new choices being skipped upon config update"). To work around the issue, conf_write_autoconf() stopped calling sym_clear_all_valid(). conf_write() must be changed accordingly. Currently, it clears SYMBOL_WRITE after the symbol is written into the .config file. This is needed to prevent it from writing the same symbol multiple times in case the symbol is declared in two or more locations. I added the new flag SYMBOL_WRITTEN, to track the symbols that have been written. Anyway, this is a cheesy workaround in order to suppress the issue as far as defconfig is concerned. Handling of choices is totally broken. sym_clear_all_valid() is called every time a user touches a symbol from the GUI interface. To reproduce it, just add a new symbol drivers/usb/gadget/legacy/Kconfig, then touch around unrelated symbols from menuconfig. USB_FUNCTIONFS will disappear from the .config file. I added the Fixes tag since it is more fatal than before. But, this has been broken since long long time before, and still it is. We should take a closer look to fix this correctly somehow.

To reproduce it, apply the following diff: | --- a/arch/arm/configs/imx_v6_v7_defconfig | +++ b/arch/arm/configs/imx_v6_v7_defconfig | @@ -345,14 +345,7 @@ CONFIG_USB_CONFIGFS_F_MIDI=y | CONFIG_USB_CONFIGFS_F_HID=y | CONFIG_USB_CONFIGFS_F_UVC=y | CONFIG_USB_CONFIGFS_F_PRINTER=y | -CONFIG_USB_ZERO=m | -CONFIG_USB_AUDIO=m | -CONFIG_USB_ETH=m | -CONFIG_USB_G_NCM=m | -CONFIG_USB_GADGETFS=m | -CONFIG_USB_FUNCTIONFS=m | -CONFIG_USB_MASS_STORAGE=m | -CONFIG_USB_G_SERIAL=m | +CONFIG_USB_FUNCTIONFS=y | CONFIG_MMC=y | CONFIG_MMC_SDHCI=y | CONFIG_MMC_SDHCI_PLTFM=y And then, run: $ make ARCH=arm mrproper imx_v6_v7_defconfig You will see CONFIG_USB_FUNCTIONFS=y is correctly contained in the .config, but not in the auto.conf. Please note drivers/usb/gadget/legacy/Kconfig is included from a choice block in drivers/usb/gadget/Kconfig. So USB_FUNCTIONFS is a choice value. This is probably a similar situation described in commit beaaddb62540 ("kconfig: tests: test defconfig when two choices interact"). When sym_calc_choice() is called, the choice symbol forgets the SYMBOL_DEF_USER unless all of its choice values are explicitly set by the user. The choice symbol is given just one chance to recall it because set_all_choice_values() is called if SYMBOL_NEED_SET_CHOICE_VALUES is set. When sym_calc_choice() is called again, the choice symbol forgets it forever, since SYMBOL_NEED_SET_CHOICE_VALUES is a one-time aid. Hence, we cannot call sym_clear_all_valid() again and again. It is crazy to repeat set and unset of internal flags. However, we cannot simply get rid of "sym->flags &= flags | ~SYMBOL_DEF_USER;" Doing so would re-introduce the problem solved by commit 5d09598d488f ("kconfig: fix new choices being skipped upon config update"). To work around the issue, conf_write_autoconf() stopped calling sym_clear_all_valid(). conf_write() must be changed accordingly. Currently, it clears SYMBOL_WRITE after the symbol is written into the .config file. This is needed to prevent it from writing the same symbol multiple times in case the symbol is declared in two or more locations. I added the new flag SYMBOL_WRITTEN, to track the symbols that have been written. Anyway, this is a cheesy workaround in order to suppress the issue as far as defconfig is concerned. Handling of choices is totally broken. sym_clear_all_valid() is called every time a user touches a symbol from the GUI interface. To reproduce it, just add a new symbol drivers/usb/gadget/legacy/Kconfig, then touch around unrelated symbols from menuconfig. USB_FUNCTIONFS will disappear from the .config file. I added the Fixes tag since it is more fatal than before. But, this has been broken since long long time before, and still it is. We should take a closer look to fix this correctly somehow.

FAILED: patch "[PATCH] bcache: fix race in btree_flush_write()" failed to apply to 4.4-stable tree

The patch below does not apply to the 4.4-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 50a260e859964002dab162513a10f91ae9d3bcd3 Mon Sep 17 00:00:00 2001 From: Coly Li <colyli(a)suse.de> Date: Fri, 28 Jun 2019 19:59:58 +0800 Subject: [PATCH] bcache: fix race in btree_flush_write() There is a race between mca_reap(), btree_node_free() and journal code btree_flush_write(), which results very rare and strange deadlock or panic and are very hard to reproduce. Let me explain how the race happens. In btree_flush_write() one btree node with oldest journal pin is selected, then it is flushed to cache device, the select-and-flush is a two steps operation. Between these two steps, there are something may happen inside the race window, - The selected btree node was reaped by mca_reap() and allocated to other requesters for other btree node. - The slected btree node was selected, flushed and released by mca shrink callback bch_mca_scan(). When btree_flush_write() tries to flush the selected btree node, firstly b->write_lock is held by mutex_lock(). If the race happens and the memory of selected btree node is allocated to other btree node, if that btree node's write_lock is held already, a deadlock very probably happens here. A worse case is the memory of the selected btree node is released, then all references to this btree node (e.g. b->write_lock) will trigger NULL pointer deference panic. This race was introduced in commit cafe56359144 ("bcache: A block layer cache"), and enlarged by commit c4dc2497d50d ("bcache: fix high CPU occupancy during journal"), which selected 128 btree nodes and flushed them one-by-one in a quite long time period. Such race is not easy to reproduce before. On a Lenovo SR650 server with 48 Xeon cores, and configure 1 NVMe SSD as cache device, a MD raid0 device assembled by 3 NVMe SSDs as backing device, this race can be observed around every 10,000 times btree_flush_write() gets called. Both deadlock and kernel panic all happened as aftermath of the race. The idea of the fix is to add a btree flag BTREE_NODE_journal_flush. It is set when selecting btree nodes, and cleared after btree nodes flushed. Then when mca_reap() selects a btree node with this bit set, this btree node will be skipped. Since mca_reap() only reaps btree node without BTREE_NODE_journal_flush flag, such race is avoided. Once corner case should be noticed, that is btree_node_free(). It might be called in some error handling code path. For example the following code piece from btree_split(), 2149 err_free2: 2150 bkey_put(b->c, &n2->key); 2151 btree_node_free(n2); 2152 rw_unlock(true, n2); 2153 err_free1: 2154 bkey_put(b->c, &n1->key); 2155 btree_node_free(n1); 2156 rw_unlock(true, n1); At line 2151 and 2155, the btree node n2 and n1 are released without mac_reap(), so BTREE_NODE_journal_flush also needs to be checked here. If btree_node_free() is called directly in such error handling path, and the selected btree node has BTREE_NODE_journal_flush bit set, just delay for 1 us and retry again. In this case this btree node won't be skipped, just retry until the BTREE_NODE_journal_flush bit cleared, and free the btree node memory.

FAILED: patch "[PATCH] bcache: fix race in btree_flush_write()" failed to apply to 4.14-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.14-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 50a260e859964002dab162513a10f91ae9d3bcd3 Mon Sep 17 00:00:00 2001 From: Coly Li <colyli(a)suse.de> Date: Fri, 28 Jun 2019 19:59:58 +0800 Subject: [PATCH] bcache: fix race in btree_flush_write() There is a race between mca_reap(), btree_node_free() and journal code btree_flush_write(), which results very rare and strange deadlock or panic and are very hard to reproduce. Let me explain how the race happens. In btree_flush_write() one btree node with oldest journal pin is selected, then it is flushed to cache device, the select-and-flush is a two steps operation. Between these two steps, there are something may happen inside the race window, - The selected btree node was reaped by mca_reap() and allocated to other requesters for other btree node. - The slected btree node was selected, flushed and released by mca shrink callback bch_mca_scan(). When btree_flush_write() tries to flush the selected btree node, firstly b->write_lock is held by mutex_lock(). If the race happens and the memory of selected btree node is allocated to other btree node, if that btree node's write_lock is held already, a deadlock very probably happens here. A worse case is the memory of the selected btree node is released, then all references to this btree node (e.g. b->write_lock) will trigger NULL pointer deference panic. This race was introduced in commit cafe56359144 ("bcache: A block layer cache"), and enlarged by commit c4dc2497d50d ("bcache: fix high CPU occupancy during journal"), which selected 128 btree nodes and flushed them one-by-one in a quite long time period. Such race is not easy to reproduce before. On a Lenovo SR650 server with 48 Xeon cores, and configure 1 NVMe SSD as cache device, a MD raid0 device assembled by 3 NVMe SSDs as backing device, this race can be observed around every 10,000 times btree_flush_write() gets called. Both deadlock and kernel panic all happened as aftermath of the race. The idea of the fix is to add a btree flag BTREE_NODE_journal_flush. It is set when selecting btree nodes, and cleared after btree nodes flushed. Then when mca_reap() selects a btree node with this bit set, this btree node will be skipped. Since mca_reap() only reaps btree node without BTREE_NODE_journal_flush flag, such race is avoided. Once corner case should be noticed, that is btree_node_free(). It might be called in some error handling code path. For example the following code piece from btree_split(), 2149 err_free2: 2150 bkey_put(b->c, &n2->key); 2151 btree_node_free(n2); 2152 rw_unlock(true, n2); 2153 err_free1: 2154 bkey_put(b->c, &n1->key); 2155 btree_node_free(n1); 2156 rw_unlock(true, n1); At line 2151 and 2155, the btree node n2 and n1 are released without mac_reap(), so BTREE_NODE_journal_flush also needs to be checked here. If btree_node_free() is called directly in such error handling path, and the selected btree node has BTREE_NODE_journal_flush bit set, just delay for 1 us and retry again. In this case this btree node won't be skipped, just retry until the BTREE_NODE_journal_flush bit cleared, and free the btree node memory.

FAILED: patch "[PATCH] bcache: fix race in btree_flush_write()" failed to apply to 5.2-stable tree

The patch below does not apply to the 5.2-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 50a260e859964002dab162513a10f91ae9d3bcd3 Mon Sep 17 00:00:00 2001 From: Coly Li <colyli(a)suse.de> Date: Fri, 28 Jun 2019 19:59:58 +0800 Subject: [PATCH] bcache: fix race in btree_flush_write() There is a race between mca_reap(), btree_node_free() and journal code btree_flush_write(), which results very rare and strange deadlock or panic and are very hard to reproduce. Let me explain how the race happens. In btree_flush_write() one btree node with oldest journal pin is selected, then it is flushed to cache device, the select-and-flush is a two steps operation. Between these two steps, there are something may happen inside the race window, - The selected btree node was reaped by mca_reap() and allocated to other requesters for other btree node. - The slected btree node was selected, flushed and released by mca shrink callback bch_mca_scan(). When btree_flush_write() tries to flush the selected btree node, firstly b->write_lock is held by mutex_lock(). If the race happens and the memory of selected btree node is allocated to other btree node, if that btree node's write_lock is held already, a deadlock very probably happens here. A worse case is the memory of the selected btree node is released, then all references to this btree node (e.g. b->write_lock) will trigger NULL pointer deference panic. This race was introduced in commit cafe56359144 ("bcache: A block layer cache"), and enlarged by commit c4dc2497d50d ("bcache: fix high CPU occupancy during journal"), which selected 128 btree nodes and flushed them one-by-one in a quite long time period. Such race is not easy to reproduce before. On a Lenovo SR650 server with 48 Xeon cores, and configure 1 NVMe SSD as cache device, a MD raid0 device assembled by 3 NVMe SSDs as backing device, this race can be observed around every 10,000 times btree_flush_write() gets called. Both deadlock and kernel panic all happened as aftermath of the race. The idea of the fix is to add a btree flag BTREE_NODE_journal_flush. It is set when selecting btree nodes, and cleared after btree nodes flushed. Then when mca_reap() selects a btree node with this bit set, this btree node will be skipped. Since mca_reap() only reaps btree node without BTREE_NODE_journal_flush flag, such race is avoided. Once corner case should be noticed, that is btree_node_free(). It might be called in some error handling code path. For example the following code piece from btree_split(), 2149 err_free2: 2150 bkey_put(b->c, &n2->key); 2151 btree_node_free(n2); 2152 rw_unlock(true, n2); 2153 err_free1: 2154 bkey_put(b->c, &n1->key); 2155 btree_node_free(n1); 2156 rw_unlock(true, n1); At line 2151 and 2155, the btree node n2 and n1 are released without mac_reap(), so BTREE_NODE_journal_flush also needs to be checked here. If btree_node_free() is called directly in such error handling path, and the selected btree node has BTREE_NODE_journal_flush bit set, just delay for 1 us and retry again. In this case this btree node won't be skipped, just retry until the BTREE_NODE_journal_flush bit cleared, and free the btree node memory.

This may result in errors like alg: aead: decryption failed on test 1 for gcm_base(ctr-aes-caam,ghash-generic): ret=74 alg: aead: Failed to load transform for gcm(aes): -2 on non-cache coherent systems, due to the fact that the GCM driver passes an IV buffer by virtual address which shares a cacheline with the auth_tag buffer passed via a scatterlist, resulting in corruption of the auth_tag when the IV is updated while the DMA mapping is live. Since the IV that is returned to the caller is only valid for CBC mode, and given that the in-kernel users of CBC (such as CTS) don't trigger the same issue as the GCM driver, let's just disable the output IV generation for all modes except CBC for the time being.

But after successfully sending the FSF command we must not use the request-object anymore, as this might result in an use-after-free (see "zfcp: fix request object use-after-free in send path causing seqno errors" ).

[PATCH 1/2] iommu/vt-d: Don't queue_iova() if there is no flush queue

by Dmitry Safonov

Intel VT-d driver was reworked to use common deferred flushing implementation. Previously there was one global per-cpu flush queue, afterwards - one per domain. Before deferring a flush, the queue should be allocated and initialized. Currently only domains with IOMMU_DOMAIN_DMA type initialize their flush queue. It's probably worth to init it for static or unmanaged domains too, but it may be arguable - I'm leaving it to iommu folks. Prevent queuing an iova flush if the domain doesn't have a queue. The defensive check seems to be worth to keep even if queue would be initialized for all kinds of domains. And is easy backportable. On 4.19.43 stable kernel it has a user-visible effect: previously for devices in si domain there were crashes, on sata devices: BUG: spinlock bad magic on CPU#6, swapper/0/1 lock: 0xffff88844f582008, .magic: 00000000, .owner: <none>/-1, .owner_cpu: 0 CPU: 6 PID: 1 Comm: swapper/0 Not tainted 4.19.43 #1 Call Trace: <IRQ> dump_stack+0x61/0x7e spin_bug+0x9d/0xa3 do_raw_spin_lock+0x22/0x8e _raw_spin_lock_irqsave+0x32/0x3a queue_iova+0x45/0x115 intel_unmap+0x107/0x113 intel_unmap_sg+0x6b/0x76 __ata_qc_complete+0x7f/0x103 ata_qc_complete+0x9b/0x26a ata_qc_complete_multiple+0xd0/0xe3 ahci_handle_port_interrupt+0x3ee/0x48a ahci_handle_port_intr+0x73/0xa9 ahci_single_level_irq_intr+0x40/0x60 __handle_irq_event_percpu+0x7f/0x19a handle_irq_event_percpu+0x32/0x72 handle_irq_event+0x38/0x56 handle_edge_irq+0x102/0x121 handle_irq+0x147/0x15c do_IRQ+0x66/0xf2 common_interrupt+0xf/0xf RIP: 0010:__do_softirq+0x8c/0x2df The same for usb devices that use ehci-pci: BUG: spinlock bad magic on CPU#0, swapper/0/1 lock: 0xffff88844f402008, .magic: 00000000, .owner: <none>/-1, .owner_cpu: 0 CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.19.43 #4 Call Trace: <IRQ> dump_stack+0x61/0x7e spin_bug+0x9d/0xa3 do_raw_spin_lock+0x22/0x8e _raw_spin_lock_irqsave+0x32/0x3a queue_iova+0x77/0x145 intel_unmap+0x107/0x113 intel_unmap_page+0xe/0x10 usb_hcd_unmap_urb_setup_for_dma+0x53/0x9d usb_hcd_unmap_urb_for_dma+0x17/0x100 unmap_urb_for_dma+0x22/0x24 __usb_hcd_giveback_urb+0x51/0xc3 usb_giveback_urb_bh+0x97/0xde tasklet_action_common.isra.4+0x5f/0xa1 tasklet_action+0x2d/0x30 __do_softirq+0x138/0x2df irq_exit+0x7d/0x8b smp_apic_timer_interrupt+0x10f/0x151 apic_timer_interrupt+0xf/0x20 </IRQ> RIP: 0010:_raw_spin_unlock_irqrestore+0x17/0x39 Cc: David Woodhouse <dwmw2(a)infradead.org> Cc: Joerg Roedel <joro(a)8bytes.org> Cc: Lu Baolu <baolu.lu(a)linux.intel.com> Cc: iommu(a)lists.linux-foundation.org Cc: <stable(a)vger.kernel.org> # 4.14+ Fixes: 13cf01744608 ("iommu/vt-d: Make use of iova deferred flushing") Signed-off-by: Dmitry Safonov <dima(a)arista.com> --- drivers/iommu/intel-iommu.c | 3 ++- drivers/iommu/iova.c | 18 ++++++++++++++---- include/linux/iova.h | 6 ++++++ 3 files changed, 22 insertions(+), 5 deletions(-) diff --git a/drivers/iommu/intel-iommu.c b/drivers/iommu/intel-iommu.c index ac4172c02244..6d1510284d21 100644 --- a/drivers/iommu/intel-iommu.c +++ b/drivers/iommu/intel-iommu.c @@ -3564,7 +3564,8 @@ static void intel_unmap(struct device *dev, dma_addr_t dev_addr, size_t size) freelist = domain_unmap(domain, start_pfn, last_pfn);
