This patch adds provision for register hdmi-audio as a alsa component and controlled bu ALSA core. Change-Id: Ic69a718c281f2dfdf00df273f8687cc7e0cd5428 Signed-off-by: Rahul Sharma <rahul.sharma@samsung.com> (cherry picked from commit a8a6034) Conflicts: drivers/gpu/drm/exynos/exynos_hdmi.c
to start when exynos5410 is configured
There is only clk-exynos5410 left to change.
…8000Hz. But the max98090 codec complains for other frequencies.
… CLK_IGNORE_UNUSED.
|
One note to be left here. If we do choose to keep on this kernel this commit "drm: remove the default DVI=true, and set hdmi audio plugin …" needs to be reverted this is done that way to keep compatibility with some bad monitors. |

commit 6623e3e upstream. The race is between lookup_get_idr_uobject and uverbs_idr_remove_uobj -> uverbs_uobject_put. We deliberately do not call sychronize_rcu after the idr_remove in uverbs_idr_remove_uobj for performance reasons, instead we call kfree_rcu() during uverbs_uobject_put. However, this means we can obtain pointers to uobj's that have already been released and must protect against krefing them using kref_get_unless_zero. ================================================================== BUG: KASAN: use-after-free in copy_ah_attr_from_uverbs.isra.2+0x860/0xa00 Read of size 4 at addr ffff88005fda1ac8 by task syz-executor2/441 CPU: 1 PID: 441 Comm: syz-executor2 Not tainted 4.15.0-rc2+ #56 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.7.5-0-ge51488c-20140602_164612-nilsson.home.kraxel.org 04/01/2014 Call Trace: dump_stack+0x8d/0xd4 print_address_description+0x73/0x290 kasan_report+0x25c/0x370 ? copy_ah_attr_from_uverbs.isra.2+0x860/0xa00 copy_ah_attr_from_uverbs.isra.2+0x860/0xa00 ? uverbs_try_lock_object+0x68/0xc0 ? modify_qp.isra.7+0xdc4/0x10e0 modify_qp.isra.7+0xdc4/0x10e0 ib_uverbs_modify_qp+0xfe/0x170 ? ib_uverbs_query_qp+0x970/0x970 ? __lock_acquire+0xa11/0x1da0 ib_uverbs_write+0x55a/0xad0 ? ib_uverbs_query_qp+0x970/0x970 ? ib_uverbs_query_qp+0x970/0x970 ? ib_uverbs_open+0x760/0x760 ? futex_wake+0x147/0x410 ? sched_clock_cpu+0x18/0x180 ? check_prev_add+0x1680/0x1680 ? do_futex+0x3b6/0xa30 ? sched_clock_cpu+0x18/0x180 __vfs_write+0xf7/0x5c0 ? ib_uverbs_open+0x760/0x760 ? kernel_read+0x110/0x110 ? lock_acquire+0x370/0x370 ? __fget+0x264/0x3b0 vfs_write+0x18a/0x460 SyS_write+0xc7/0x1a0 ?

commit e89d469 upstream. The below commit added a call to ->destroy() on init failure, but multiq still frees ->queues on error in init, but ->queues is also freed by ->destroy() thus we get double free and corrupted memory.

After commit 9406279 ("tcp: defer shutdown(SEND_SHUTDOWN) for TCP_SYN_RECV sockets"), the above causes the child to reach the accept syscall in FIN_WAIT1 status. Eric noted we can relax the existing assertion in __inet_accept() Reported-by: Christoph Paasch <cpaasch@apple.com> Closes: multipath-tcp/mptcp_net-next#490 Suggested-by: Eric Dumazet <edumazet@google.com> Fixes: 9406279 ("tcp: defer shutdown(SEND_SHUTDOWN) for TCP_SYN_RECV sockets") Reviewed-by: Eric Dumazet <edumazet@google.com> Link: https://lore.kernel.org/r/23ab880a44d8cfd967e84de8b93dbf48848e3d8c.1716299669.git.pabeni@redhat.com Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
