[PATCH] drm/i915/gem: Propagate error from cancelled submit due to context closure

by Chris Wilson

In the course of discovering and closing many races with context closure and execbuf submission, since commit 61231f6bd056 ("drm/i915/gem: Check that the context wasn't closed during setup") we started checking that the context was not closed by another userspace thread during the execbuf ioctl. In doing so we cancelled the inflight request (by telling it to be skipped), but kept reporting success since we do submit a request, albeit one that doesn't execute. As the error is known before we return from the ioctl, we can report the error we detect immediately, rather than leave it on the fence status. With the immediate propagation of the error, it is easier for userspace to handle.

[PATCH] powerpc/hotplug: assign hot added LMB to the right node

by Laurent Dufour

This patch applies to 5.9 and earlier kernels only. Since 5.10, this has been fortunately fixed by the commit e5e179aa3a39 ("pseries/drmem: don't cache node id in drmem_lmb struct"). When LMBs are added to a running system, the node id assigned to the LMB is fetched from the temporary DT node provided by the hypervisor. However, LMBs added are always assigned to the first online node. This is a mistake and this is because hot_add_drconf_scn_to_nid() called by lmb_set_nid() is checking for the LMB flags DRCONF_MEM_ASSIGNED which is set later in dlpar_add_lmb(). To fix this issue, simply set that flag earlier in dlpar_add_lmb(). Note, this code has been rewrote in 5.10 and thus this fix has no meaning since this version.

[PATCH v3] proc: use untagged_addr() for pagemap_read addresses

by Miles Chen

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 Cc: Andrew Morton <akpm(a)linux-foundation.org> 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 v2] proc: use untagged_addr() for pagemap_read addresses

by Miles Chen

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 usespace pointers in pagemap_read(). I tested with 5.10-rc4 and the issue remains. Explaination 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 baed 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 Cc: Andrew Morton <akpm(a)linux-foundation.org> 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.deacon(a)arm.com> Cc: Eric W.
