[PATCH v2] drm/prime: fix extracting of the DMA addresses from a scatterlist

by Marek Szyprowski

Scatterlist elements contains both pages and DMA addresses, but one should not assume 1:1 relation between them. The sg->length is the size of the physical memory chunk described by the sg->page, while sg_dma_len(sg) is the size of the DMA (IO virtual) chunk described by the sg_dma_address(sg). The proper way of extracting both: pages and DMA addresses of the whole buffer described by a scatterlist it to iterate independently over the sg->pages/sg->length and sg_dma_address(sg)/sg_dma_len(sg) entries.

[PATCH v3 1/2] ACPI: PM: Add acpi_[un]register_wakeup_handler()

by Hans de Goede

Since commit fdde0ff8590b ("ACPI: PM: s2idle: Prevent spurious SCIs from waking up the system") the SCI triggering without there being a wakeup cause recognized by the ACPI sleep code will no longer wakeup the system. This works as intended, but this is a problem for devices where the SCI is shared with another device which is also a wakeup source. In the past these, from the pov of the ACPI sleep code, spurious SCIs would still cause a wakeup so the wakeup from the device sharing the interrupt would actually wakeup the system. This now no longer works. This is a problem on e.g. Bay Trail-T and Cherry Trail devices where some peripherals (typically the XHCI controller) can signal a Power Management Event (PME) to the Power Management Controller (PMC) to wakeup the system, this uses the same interrupt as the SCI. These wakeups are handled through a special INT0002 ACPI device which checks for events in the GPE0a_STS for this and takes care of acking the PME so that the shared interrupt stops triggering. The change to the ACPI sleep code to ignore the spurious SCI, causes the system to no longer wakeup on these PME events. To make things worse this means that the INT0002 device driver interrupt handler will no longer run, causing the PME to not get cleared and resulting in the system hanging. Trying to wakeup the system after such a PME through e.g. the power button no longer works. Add an acpi_register_wakeup_handler() function which registers a handler to be called from acpi_s2idle_wake() and when the handler returns true, return true from acpi_s2idle_wake(). The INT0002 driver will use this mechanism to check the GPE0a_STS register from acpi_s2idle_wake() and to tell the system to wakeup if a PME is signaled in the register.

[PATCH] net: dsa: mt7530: fix null pointer dereferencing in port5 setup

by Chuanhong Guo

The 2nd gmac of mediatek soc ethernet may not be connected to a PHY and a phy-handle isn't always available. Unfortunately, mt7530 dsa driver assumes that the 2nd gmac is always connected to switch port 5 and setup mt7530 according to phy address of 2nd gmac node, causing null pointer dereferencing when phy-handle isn't defined in dts. This commit fix this setup code by checking return value of of_parse_phandle before using it.

[PATCH] nvme-fc: Revert - add module to ops template to allow module references

by James Smart

This patch reverts the commit for nvme_fc: add module to ops template to allow module references The original patch was to resolve the lldd being able to be unloaded while being used to talk to the boot device of the system. However, the end result of the original patch is that any driver unload while a nvme controller is live via the lldd is now being prohibited. Given the module reference, the module teardown routine can't be called, thus there's no way, other than manual actions to terminate the controllers. -- james Fixes: 863fbae929c7 ("nvme_fc: add module to ops template to allow module references") Cc: <stable(a)vger.kernel.org> # v5.4+ Signed-off-by: James Smart <jsmart2021(a)gmail.com> Cc: Himanshu Madhani <himanshu.madhani(a)oracle.com> CC: Christoph Hellwig <hch(a)lst.de> CC: Keith Busch <kbusch(a)kernel.org> --- drivers/nvme/host/fc.c | 14 ++------------ drivers/nvme/target/fcloop.c | 1 - drivers/scsi/lpfc/lpfc_nvme.c | 2 -- drivers/scsi/qla2xxx/qla_nvme.c | 1 - include/linux/nvme-fc-driver.h | 4 ---- 5 files changed, 2 insertions(+), 20 deletions(-) diff --git a/drivers/nvme/host/fc.c b/drivers/nvme/host/fc.c index a8bf2fb1287b..7dfc4a2ecf1e 100644 --- a/drivers/nvme/host/fc.c +++ b/drivers/nvme/host/fc.c @@ -342,8 +342,7 @@ nvme_fc_register_localport(struct nvme_fc_port_info *pinfo, !template->ls_req || !template->fcp_io || !template->ls_abort || !template->fcp_abort || !template->max_hw_queues || !template->max_sgl_segments || - !template->max_dif_sgl_segments || !template->dma_boundary || - !template->module) { + !template->max_dif_sgl_segments || !template->dma_boundary) { ret = -EINVAL; goto out_reghost_failed; } @@ -2016,7 +2015,6 @@ nvme_fc_ctrl_free(struct kref *ref) { struct nvme_fc_ctrl *ctrl = container_of(ref, struct nvme_fc_ctrl, ref); - struct nvme_fc_lport *lport = ctrl->lport; unsigned long flags; if (ctrl->ctrl.tagset) { @@ -2043,7 +2041,6 @@ nvme_fc_ctrl_free(struct kref *ref) if (ctrl->ctrl.opts) nvmf_free_options(ctrl->ctrl.opts); kfree(ctrl); - module_put(lport->ops->module); } static void @@ -3074,15 +3071,10 @@ nvme_fc_init_ctrl(struct device *dev, struct nvmf_ctrl_options *opts, goto out_fail; } - if (!try_module_get(lport->ops->module)) { - ret = -EUNATCH; - goto out_free_ctrl; - } - idx = ida_simple_get(&nvme_fc_ctrl_cnt, 0, 0, GFP_KERNEL); if (idx < 0) { ret = -ENOSPC; - goto out_mod_put; + goto out_free_ctrl; } ctrl->ctrl.opts = opts; @@ -3232,8 +3224,6 @@ nvme_fc_init_ctrl(struct device *dev, struct nvmf_ctrl_options *opts, out_free_ida: put_device(ctrl->dev); ida_simple_remove(&nvme_fc_ctrl_cnt, ctrl->cnum); -out_mod_put: - module_put(lport->ops->module); out_free_ctrl: kfree(ctrl); out_fail: diff --git a/drivers/nvme/target/fcloop.c b/drivers/nvme/target/fcloop.c index 9861fcea39f6..f69ce66e2d44 100644 --- a/drivers/nvme/target/fcloop.c +++ b/drivers/nvme/target/fcloop.c @@ -875,7 +875,6 @@ fcloop_targetport_delete(struct nvmet_fc_target_port *targetport) #define FCLOOP_DMABOUND_4G 0xFFFFFFFF static struct nvme_fc_port_template fctemplate = { - .module = THIS_MODULE, .localport_delete = fcloop_localport_delete, .remoteport_delete = fcloop_remoteport_delete, .create_queue = fcloop_create_queue, diff --git a/drivers/scsi/lpfc/lpfc_nvme.c b/drivers/scsi/lpfc/lpfc_nvme.c index f6c8963c915d..db4a04a207ec 100644 --- a/drivers/scsi/lpfc/lpfc_nvme.c +++ b/drivers/scsi/lpfc/lpfc_nvme.c @@ -1985,8 +1985,6 @@ lpfc_nvme_fcp_abort(struct nvme_fc_local_port *pnvme_lport, /* Declare and initialization an instance of the FC NVME template. */ static struct nvme_fc_port_template lpfc_nvme_template = { - .module = THIS_MODULE, - /* initiator-based functions */ .localport_delete = lpfc_nvme_localport_delete, .remoteport_delete = lpfc_nvme_remoteport_delete, diff --git a/drivers/scsi/qla2xxx/qla_nvme.c b/drivers/scsi/qla2xxx/qla_nvme.c index bfcd02fdf2b8..941aa53363f5 100644 --- a/drivers/scsi/qla2xxx/qla_nvme.c +++ b/drivers/scsi/qla2xxx/qla_nvme.c @@ -610,7 +610,6 @@ static void qla_nvme_remoteport_delete(struct nvme_fc_remote_port *rport) } static struct nvme_fc_port_template qla_nvme_fc_transport = { - .module = THIS_MODULE, .localport_delete = qla_nvme_localport_delete, .remoteport_delete = qla_nvme_remoteport_delete, .create_queue = qla_nvme_alloc_queue, diff --git a/include/linux/nvme-fc-driver.h b/include/linux/nvme-fc-driver.h index 6d0d70f3219c..10f81629b9ce 100644 --- a/include/linux/nvme-fc-driver.h +++ b/include/linux/nvme-fc-driver.h @@ -270,8 +270,6 @@ struct nvme_fc_remote_port { * * Host/Initiator Transport Entrypoints/Parameters: * - * @module: The LLDD module using the interface - * * @localport_delete: The LLDD initiates deletion of a localport via * nvme_fc_deregister_localport().

Its filename was selftests-vm-fix-map_hugetlb-length-used-for-testing-read-and-write.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Christophe Leroy <christophe.leroy(a)c-s.fr> Subject: selftests/vm: fix map_hugetlb length used for testing read and write Commit fa7b9a805c79 ("tools/selftest/vm: allow choosing mem size and page size in map_hugetlb") added the possibility to change the size of memory mapped for the test, but left the read and write test using the default value. This is unnoticed when mapping a length greater than the default one, but segfaults otherwise. Fix read_bytes() and write_bytes() by giving them the real length. Also fix the call to munmap().

[merged] selftests-vm-drop-dependencies-on-page-flags-from-mlock2-tests.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: selftests: vm: drop dependencies on page flags from mlock2 tests has been removed from the -mm tree. Its filename was selftests-vm-drop-dependencies-on-page-flags-from-mlock2-tests.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Michal Hocko <mhocko(a)suse.com> Subject: selftests: vm: drop dependencies on page flags from mlock2 tests It was noticed that mlock2 tests are failing after 9c4e6b1a7027f ("mm, mlock, vmscan: no more skipping pagevecs") because the patch has changed the timing on when the page is added to the unevictable LRU list and thus gains the unevictable page flag. The test was just too dependent on the implementation details which were true at the time when it was introduced. Page flags and the timing when they are set is something no userspace should ever depend on. The test should be testing only for the user observable contract of the tested syscalls. Those are defined pretty well for the mlock and there are other means for testing them. In fact this is already done and testing for page flags can be safely dropped to achieve the aimed purpose. Present bits can be checked by /proc/<pid>/smaps RSS field and the locking state by VmFlags although I would argue that Locked: field would be more appropriate. Drop all the page flag machinery and considerably simplify the test. This should be more robust for future kernel changes while checking the promised contract is still valid.

[merged] slub-improve-bit-diffusion-for-freelist-ptr-obfuscation.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: slub: improve bit diffusion for freelist ptr obfuscation has been removed from the -mm tree. Its filename was slub-improve-bit-diffusion-for-freelist-ptr-obfuscation.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Kees Cook <keescook(a)chromium.org> Subject: slub: improve bit diffusion for freelist ptr obfuscation Under CONFIG_SLAB_FREELIST_HARDENED=y, the obfuscation was relatively weak in that the ptr and ptr address were usually so close that the first XOR would result in an almost entirely 0-byte value[1], leaving most of the "secret" number ultimately being stored after the third XOR. A single blind memory content exposure of the freelist was generally sufficient to learn the secret. Add a swab() call to mix bits a little more. This is a cheap way (1 cycle) to make attacks need more than a single exposure to learn the secret (or to know _where_ the exposure is in memory). kmalloc-32 freelist walk, before: ptr ptr_addr stored value secret ffff90c22e019020@ffff90c22e019000 is 86528eb656b3b5bd (86528eb656b3b59d) ffff90c22e019040@ffff90c22e019020 is 86528eb656b3b5fd (86528eb656b3b59d) ffff90c22e019060@ffff90c22e019040 is 86528eb656b3b5bd (86528eb656b3b59d) ffff90c22e019080@ffff90c22e019060 is 86528eb656b3b57d (86528eb656b3b59d) ffff90c22e0190a0@ffff90c22e019080 is 86528eb656b3b5bd (86528eb656b3b59d) ... after: ptr ptr_addr stored value secret ffff9eed6e019020@ffff9eed6e019000 is 793d1135d52cda42 (86528eb656b3b59d) ffff9eed6e019040@ffff9eed6e019020 is 593d1135d52cda22 (86528eb656b3b59d) ffff9eed6e019060@ffff9eed6e019040 is 393d1135d52cda02 (86528eb656b3b59d) ffff9eed6e019080@ffff9eed6e019060 is 193d1135d52cdae2 (86528eb656b3b59d) ffff9eed6e0190a0@ffff9eed6e019080 is f93d1135d52cdac2 (86528eb656b3b59d) [1] https://blog.infosectcbr.com.au/2020/03/weaknesses-in-linux-kernel-heap.html Link: http://lkml.kernel.org/r/202003051623.AF4F8CB@keescook Fixes: 2482ddec670f ("mm: add SLUB free list pointer obfuscation") Reported-by: Silvio Cesare <silvio.cesare(a)gmail.com> Signed-off-by: Kees Cook <keescook(a)chromium.org> Cc: Christoph Lameter <cl(a)linux.com> Cc: Pekka Enberg <penberg(a)kernel.org> Cc: David Rientjes <rientjes(a)google.com> Cc: Joonsoo Kim <iamjoonsoo.kim(a)lge.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> --- mm/slub.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/mm/slub.c~slub-improve-bit-diffusion-for-freelist-ptr-obfuscation +++ a/mm/slub.c @@ -259,7 +259,7 @@ static inline void *freelist_ptr(const s * freepointer to be restored incorrectly. */ return (void *)((unsigned long)ptr ^ s->random ^ - (unsigned long)kasan_reset_tag((void *)ptr_addr)); + swab((unsigned long)kasan_reset_tag((void *)ptr_addr))); #else return ptr; #endif _ Patches currently in -mm which might be from keescook(a)chromium.org are shmem-distribute-switch-variables-for-initialization.patch lib-test_stackinitc-xfail-switch-variable-init-tests.patch ubsan-add-trap-instrumentation-option.patch ubsan-split-bounds-checker-from-other-options.patch lkdtm-bugs-add-arithmetic-overflow-and-array-bounds-checks.patch ubsan-check-panic_on_warn.patch kasan-unset-panic_on_warn-before-calling-panic.patch ubsan-include-bug-type-in-report-header.patch

[merged] getdelays-fix-netlink-attribute-length.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: tools/accounting/getdelays.c: fix netlink attribute length has been removed from the -mm tree. Its filename was getdelays-fix-netlink-attribute-length.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: David Ahern <dsahern(a)kernel.org> Subject: tools/accounting/getdelays.c: fix netlink attribute length A recent change to the netlink code: 6e237d099fac ("netlink: Relax attr validation for fixed length types") logs a warning when programs send messages with invalid attributes (e.g., wrong length for a u32). Yafang reported this error message for tools/accounting/getdelays.c. send_cmd() is wrongly adding 1 to the attribute length. As noted in include/uapi/linux/netlink.h nla_len should be NLA_HDRLEN + payload length, so drop the +1.
