[merged] proc-use-untagged_addr-for-pagemap_read-addresses.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: proc: use untagged_addr() for pagemap_read addresses has been removed from the -mm tree. Its filename was proc-use-untagged_addr-for-pagemap_read-addresses.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Miles Chen <miles.chen(a)mediatek.com> Subject: proc: use untagged_addr() for pagemap_read addresses When we try to visit the pagemap of a tagged userspace pointer, we find that the start_vaddr is not correct because of the tag. To fix it, we should untag the userspace pointers in pagemap_read(). I tested with 5.10-rc4 and the issue remains. Explanation from Catalin in [1]: :Arguably, that's a user-space bug since tagged file offsets were never :supported. In this case it's not even a tag at bit 56 as per the arm64 :tagged address ABI but rather down to bit 47. You could say that the :problem is caused by the C library (malloc()) or whoever created the :tagged vaddr and passed it to this function. It's not a kernel :regression as we've never supported it. : :Now, pagemap is a special case where the offset is usually not generated :as a classic file offset but rather derived by shifting a user virtual :address. I guess we can make a concession for pagemap (only) and allow :such offset with the tag at bit (56 - PAGE_SHIFT + 3). My test code is based on [2]: A userspace pointer which has been tagged by 0xb4: 0xb400007662f541c8 === userspace program === uint64 OsLayer::VirtualToPhysical(void *vaddr) { uint64 frame, paddr, pfnmask, pagemask; int pagesize = sysconf(_SC_PAGESIZE); off64_t off = ((uintptr_t)vaddr) / pagesize * 8; // off = 0xb400007662f541c8 / pagesize * 8 = 0x5a00003b317aa0 int fd = open(kPagemapPath, O_RDONLY); ... if (lseek64(fd, off, SEEK_SET) != off || read(fd, &frame, 8) != 8) { int err = errno; string errtxt = ErrorString(err); if (fd >= 0) close(fd); return 0; } ... } === kernel fs/proc/task_mmu.c === static ssize_t pagemap_read(struct file *file, char __user *buf, size_t count, loff_t *ppos) { ... src = *ppos; svpfn = src / PM_ENTRY_BYTES; // svpfn == 0xb400007662f54 start_vaddr = svpfn << PAGE_SHIFT; // start_vaddr == 0xb400007662f54000 end_vaddr = mm->task_size; /* watch out for wraparound */ // svpfn == 0xb400007662f54 // (mm->task_size >> PAGE) == 0x8000000 if (svpfn > mm->task_size >> PAGE_SHIFT) // the condition is true because of the tag 0xb4 start_vaddr = end_vaddr; ret = 0; while (count && (start_vaddr < end_vaddr)) { // we cannot visit correct entry because start_vaddr is set to end_vaddr int len; unsigned long end; ... } ... } [1] https://lore.kernel.org/patchwork/patch/1343258/ [2] https://github.com/stressapptest/stressapptest/blob/master/src/os.cc#L158 Link: https://lkml.kernel.org/r/20201204024347.8295-1-miles.chen@mediatek.com Signed-off-by: Miles Chen <miles.chen(a)mediatek.com> Reviewed-by: Vincenzo Frascino <vincenzo.frascino(a)arm.com> Reviewed-by: Catalin Marinas <catalin.marinas(a)arm.com> Cc: Alexey Dobriyan <adobriyan(a)gmail.com> Cc: Andrey Konovalov <andreyknvl(a)google.com> Cc: Alexander Potapenko <glider(a)google.com> Cc: Vincenzo Frascino <vincenzo.frascino(a)arm.com> Cc: Andrey Ryabinin <aryabinin(a)virtuozzo.com> Cc: Catalin Marinas <catalin.marinas(a)arm.com> Cc: Dmitry Vyukov <dvyukov(a)google.com> Cc: Marco Elver <elver(a)google.com> Cc: Will Deacon <will(a)kernel.org> Cc: Eric W.

[PATCH] drm/rockchip: dsi: remove extra component_del() call

by Thomas Hebb

commit cf6d100dd238 ("drm/rockchip: dsi: add dual mipi support") added this devcnt field and call to component_del(). However, these both appear to be erroneous changes left over from an earlier version of the patch. In the version merged, nothing ever modifies devcnt, meaning component_del() runs unconditionally and in addition to the component_del() calls in dw_mipi_dsi_rockchip_host_detach(). The second call fails to delete anything and produces a warning in dmesg. If we look at the previous version of the patch[1], however, we see that it had logic to calculate devcnt and call component_add() in certain situations. This was removed in v6, and the fact that the deletion code was not appears to have been an oversight.

However, when optprobe decodes a target function it finds INT3 and gives up the jump optimization. Instead of giving up any INT3 detection, check whether the rest of the bytes to the end of the function are INT3. If all of them are INT3, those come from the linker. In that case, continue the optprobe jump optimization.

✅ PASS: Test report for kernel 5.9.14 (stable-queue)

by CKI Project

Hello, We ran automated tests on a recent commit from this kernel tree: Kernel repo: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git Commit: a6042d4761e7 - Kbuild: do not emit debug info for assembly with LLVM_IAS=1 The results of these automated tests are provided below. Overall result: PASSED Merge: OK Compile: OK Tests: OK All kernel binaries, config files, and logs are available for download here: https://arr-cki-prod-datawarehouse-public.s3.amazonaws.com/index.html?prefi… Please reply to this email if you have any questions about the tests that we ran or if you have any suggestions on how to make future tests more effective. ,-. ,-.
