[PATCH AUTOSEL 5.15 08/25] udmabuf: Set ubuf->sg = NULL if the creation of sg table fails

by Sasha Levin

From: Vivek Kasireddy <vivek.kasireddy(a)intel.com> [ Upstream commit d9c04a1b7a15b5e74b2977461d9511e497f05d8f ] When userspace tries to map the dmabuf and if for some reason (e.g. OOM) the creation of the sg table fails, ubuf->sg needs to be set to NULL. Otherwise, when the userspace subsequently closes the dmabuf fd, we'd try to erroneously free the invalid sg table from release_udmabuf resulting in the following crash reported by syzbot: general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] PREEMPT SMP KASAN KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007] CPU: 0 PID: 3609 Comm: syz-executor487 Not tainted 5.19.0-syzkaller-13930-g7ebfc85e2cd7 #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 07/22/2022 RIP: 0010:dma_unmap_sgtable include/linux/dma-mapping.h:378 [inline] RIP: 0010:put_sg_table drivers/dma-buf/udmabuf.c:89 [inline] RIP: 0010:release_udmabuf+0xcb/0x4f0 drivers/dma-buf/udmabuf.c:114 Code: 48 89 fa 48 c1 ea 03 80 3c 02 00 0f 85 2b 04 00 00 48 8d 7d 0c 4c 8b 63 30 48 b8 00 00 00 00 00 fc ff df 48 89 fa 48 c1 ea 03 <0f> b6 14 02 48 89 f8 83 e0 07 83 c0 03 38 d0 7c 08 84 d2 0f 85 e2 RSP: 0018:ffffc900037efd30 EFLAGS: 00010246 RAX: dffffc0000000000 RBX: ffffffff8cb67800 RCX: 0000000000000000 RDX: 0000000000000000 RSI: ffffffff84ad27e0 RDI: 0000000000000000 RBP: fffffffffffffff4 R08: 0000000000000005 R09: 0000000000000000 R10: 0000000000000000 R11: 000000000008c07c R12: ffff88801fa05000 R13: ffff888073db07e8 R14: ffff888025c25440 R15: 0000000000000000 FS: 0000555555fc4300(0000) GS:ffff8880b9a00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007fc1c0ce06e4 CR3: 00000000715e6000 CR4: 00000000003506f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Call Trace: <TASK> dma_buf_release+0x157/0x2d0 drivers/dma-buf/dma-buf.c:78 __dentry_kill+0x42b/0x640 fs/dcache.c:612 dentry_kill fs/dcache.c:733 [inline] dput+0x806/0xdb0 fs/dcache.c:913 __fput+0x39c/0x9d0 fs/file_table.c:333 task_work_run+0xdd/0x1a0 kernel/task_work.c:177 ptrace_notify+0x114/0x140 kernel/signal.c:2353 ptrace_report_syscall include/linux/ptrace.h:420 [inline] ptrace_report_syscall_exit include/linux/ptrace.h:482 [inline] syscall_exit_work kernel/entry/common.c:249 [inline] syscall_exit_to_user_mode_prepare+0x129/0x280 kernel/entry/common.c:276 __syscall_exit_to_user_mode_work kernel/entry/common.c:281 [inline] syscall_exit_to_user_mode+0x9/0x50 kernel/entry/common.c:294 do_syscall_64+0x42/0xb0 arch/x86/entry/common.c:86 entry_SYSCALL_64_after_hwframe+0x63/0xcd RIP: 0033:0x7fc1c0c35b6b Code: 0f 05 48 3d 00 f0 ff ff 77 45 c3 0f 1f 40 00 48 83 ec 18 89 7c 24 0c e8 63 fc ff ff 8b 7c 24 0c 41 89 c0 b8 03 00 00 00 0f 05 <48> 3d 00 f0 ff ff 77 35 44 89 c7 89 44 24 0c e8 a1 fc ff ff 8b 44 RSP: 002b:00007ffd78a06090 EFLAGS: 00000293 ORIG_RAX: 0000000000000003 RAX: 0000000000000000 RBX: 0000000000000007 RCX: 00007fc1c0c35b6b RDX: 0000000020000280 RSI: 0000000040086200 RDI: 0000000000000006 RBP: 0000000000000007 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000000000 R11: 0000000000000293 R12: 000000000000000c R13: 0000000000000003 R14: 00007fc1c0cfe4a0 R15: 00007ffd78a06140 </TASK> Modules linked in: ---[ end trace 0000000000000000 ]--- RIP: 0010:dma_unmap_sgtable include/linux/dma-mapping.h:378 [inline] RIP: 0010:put_sg_table drivers/dma-buf/udmabuf.c:89 [inline] RIP: 0010:release_udmabuf+0xcb/0x4f0 drivers/dma-buf/udmabuf.c:114 Reported-by: syzbot+c80e9ef5d8bb45894db0(a)syzkaller.appspotmail.com Cc: Gerd Hoffmann <kraxel(a)redhat.com> Signed-off-by: Vivek Kasireddy <vivek.kasireddy(a)intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20220825063522.801264-1-vivek.… Signed-off-by: Gerd Hoffmann <kraxel(a)redhat.com> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- drivers/dma-buf/udmabuf.c | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) diff --git a/drivers/dma-buf/udmabuf.c b/drivers/dma-buf/udmabuf.c index 38e8767ec371..bf11d32205f3 100644 --- a/drivers/dma-buf/udmabuf.c +++ b/drivers/dma-buf/udmabuf.c @@ -124,17 +124,20 @@ static int begin_cpu_udmabuf(struct dma_buf *buf, { struct udmabuf *ubuf = buf->priv; struct device *dev = ubuf->device->this_device; + int ret = 0; if (!ubuf->sg) { ubuf->sg = get_sg_table(dev, buf, direction); - if (IS_ERR(ubuf->sg)) - return PTR_ERR(ubuf->sg); + if (IS_ERR(ubuf->sg)) { + ret = PTR_ERR(ubuf->sg); + ubuf->sg = NULL; + } } else { dma_sync_sg_for_cpu(dev, ubuf->sg->sgl, ubuf->sg->nents, direction); } - return 0; + return ret; } static int end_cpu_udmabuf(struct dma_buf *buf, -- 2.35.1

[PATCH AUTOSEL 5.15 04/25] drm/komeda: Fix handling of atomic commits in the atomic_commit_tail hook

by Sasha Levin

From: Liviu Dudau <liviu.dudau(a)arm.com> [ Upstream commit eaa225b6b52233d45457fd33730e1528c604d92d ] Komeda driver relies on the generic DRM atomic helper functions to handle commits. It only implements an atomic_commit_tail hook for the mode_config_helper_funcs and even that one is pretty close to the generic implementation with the exception of additional dma_fence signalling. What the generic helper framework doesn't do is waiting for the actual hardware to signal that the commit parameters have been written into the appropriate registers. As we signal CRTC events only on the irq handlers, we need to flush the configuration and wait for the hardware to respond. Add the Komeda specific implementation for atomic_commit_hw_done() that flushes and waits for flip done before calling drm_atomic_helper_commit_hw_done(). The fix was prompted by a patch from Carsten Haitzler where he was trying to solve the same issue but in a different way that I think can lead to wrong event signaling to userspace.

[PATCH v2 00/16] slab: Introduce kmalloc_size_roundup()

by Kees Cook

Hi, The main details on this series are in patch #2's commit log. It's long, so I won't repeat it again here for the v2. As before, I've tried to trim the CC list. v2: - _keep_ ksize(), but remove instrumentation (makes patch series smaller) - reorganized skbuff logic to avoid yet more copy/paste code - added a WARN to a separate skbuff ksize usage - add new refactorings: bpf, openvswitch, devres, mempool, kasan - dropped "independent" patches: iwlwifi, x86/microcode/AMD (sent separately) v1: https://lore.kernel.org/lkml/20220922031013.2150682-1-keescook@chromium.org Notes: Originally when I was going to entirely remove ksize(), there were a handful for refactorings that just needed to do ksize -> __ksize. In the end, it was cleaner to actually leave ksize() as a real function, just without the kasan instrumentation. I wonder, however, if it should be converted into a static inline now? I dropped Jakub's Ack because I refactored that code a bunch more. The 2 patches that didn't need to call kmalloc_size_roundup() don't need to be part of this series. (One is already in -next, actually.) I'd like to land at least the first two patches in the coming v6.1 merge window so that the per-subsystem patches can be sent to their various subsystems directly. Vlastimil, what you think?
