2018-07-30media: v4l: vsp1: Fix deadlock in VSPDL DRM pipelinesLaurent Pinchart
The VSP uses a lock to protect the BRU and BRS assignment when configuring pipelines. The lock is taken in vsp1_du_atomic_begin() and released in vsp1_du_atomic_flush(), as well as taken and released in vsp1_du_setup_lif(). This guards against multiple pipelines trying to assign the same BRU and BRS at the same time. The DRM framework calls the .atomic_begin() operations in a loop over all CRTCs included in an atomic commit. On a VSPDL (the only VSP type where this matters), a single VSP instance handles two CRTCs, with a single lock. This results in a deadlock when the .atomic_begin() operation is called on the second CRTC. The DRM framework serializes atomic commits that affect the same CRTCs, but doesn't know about two CRTCs sharing the same VSPDL. Two commits affecting the VSPDL LIF0 and LIF1 respectively can thus race each other, hence the need for a lock. This could be fixed on the DRM side by forcing serialization of commits affecting CRTCs backed by the same VSPDL, but that would negatively affect performances, as the locking is only needed when the BRU and BRS need to be reassigned, which is an uncommon case. The lock protects the whole .atomic_begin() to .atomic_flush() sequence. The only operation that can occur in-between is vsp1_du_atomic_update(), which doesn't touch the BRU and BRS, and thus doesn't need to be protected by the lock. We can thus only take the lock around the pipeline setup calls in vsp1_du_atomic_flush(), which fixes the deadlock.

The repeat period is read from a static array. If a keydown event is reported from bpf with a high protocol number, we read out of bounds. This is unlikely to end up with a reasonable repeat period at the best of times, in which case no timely key up event is generated.

2018-07-30netfilter: nf_tables: Add native tproxy supportMáté Eckl
A great portion of the code is taken from xt_TPROXY.c There are some changes compared to the iptables implementation: - tproxy statement is not terminal here - Either address or port has to be specified, but at least one of them is necessary. If one of them is not specified, the evaluation will be performed with the original attribute of the packet (ie. target port is not specified => the packet's dport will be used). To make this work in inet tables, the tproxy structure has a family member (typically called priv->family) which is not necessarily equal to ctx->family. priv->family can have three values legally: - NFPROTO_IPV4 if the table family is ip OR if table family is inet, but an ipv4 address is specified as a target address. The rule only evaluates ipv4 packets in this case. - NFPROTO_IPV6 if the table family is ip6 OR if table family is inet, but an ipv6 address is specified as a target address. The rule only evaluates ipv6 packets in this case. - NFPROTO_UNSPEC if the table family is inet AND if only the port is specified. The rule will evaluate both ipv4 and ipv6 packets.

When building the kernel as Thumb-2 with binutils 2.29 or newer, if the assembler has seen the .type directive (via ENDPROC()) for a symbol, it automatically handles the setting of the lowest bit when the symbol is used with ADR. The badr macro on the other hand handles this lowest bit manually. This leads to a jump to a wrong address in the wrong state in the syscall return path: Internal error: Oops - undefined instruction: 0 [#2] SMP THUMB2 Modules linked in: CPU: 0 PID: 652 Comm: modprobe Tainted: G D 4.18.0-rc3+ #8 PC is at ret_fast_syscall+0x4/0x62 LR is at sys_brk+0x109/0x128 pc : [<80101004>] lr : [<801c8a35>] psr: 60000013 Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none Control: 50c5387d Table: 9e82006a DAC: 00000051 Process modprobe (pid: 652, stack limit = 0x(ptrval)) 80101000 <ret_fast_syscall>: 80101000: b672 cpsid i 80101002: f8d9 2008 ldr.w r2, [r9, #8] 80101006: f1b2 4ffe cmp.w r2, #2130706432 ; 0x7f000000 80101184 <local_restart>: 80101184: f8d9 a000 ldr.w sl, [r9] 80101188: e92d 0030 stmdb sp!, {r4, r5} 8010118c: f01a 0ff0 tst.w sl, #240 ; 0xf0 80101190: d117 bne.n 801011c2 <__sys_trace> 80101192: 46ba mov sl, r7 80101194: f5ba 7fc8 cmp.w sl, #400 ; 0x190 80101198: bf28 it cs 8010119a: f04f 0a00 movcs.w sl, #0 8010119e: f3af 8014 nop.w {20} 801011a2: f2af 1ea2 subw lr, pc, #418 ; 0x1a2 To fix this, add a new symbol name which doesn't have ENDPROC used on it and use that with badr.

2018-07-29net-next: mediatek: cleanup unnecessary get chip id and its userSean Wang
Since driver is devicetree-based, all device type and charateristic can be determined by the compatible string and its data. It's unnecessary to create another dependent function to check chip ID and then decide whether the specific funciton is being supported on a certain device. It can be totally replaced by the existing flag, so a cleanup is made by removing the function and the only user, HWLRO. MT2701 also have a missing HWLRO support in old code, so add it the same patch. Signed-off-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Gal, started with three cleanups to reflect the actual hardware vxlan state - reflect 4789 UDP port default addition to software database - check maximum number of vxlan UDP ports - cleanup an unused member in vxlan work Then Gal provides performance optimization by replacing the vxlan radix tree with a hash table. Measuring mlx5e_vxlan_lookup_port execution time: Radix Tree Hash Table --------------- ------------ ------------ Single Stream 161 ns 79 ns (51% improvement) Multi Stream 259 ns 136 ns (47% improvement) Measuring UDP stream packet rate, single fully utilized TX core: Radix Tree: 498,300 PPS Hash Table: 555,468 PPS (11% improvement) Next, from Saeed, vxlan refactoring to allow sharing the vxlan table between different mlx5 netdevice instances like PF and VF representors, this is done by making mlx5 vxlan interface more generic and decoupling it from PF netdevice structures and logic, then moving it into mlx5 core as a low level interface so it can be used by VF representors, which is illustrated in the last patch of the serious. ==================== Signed-off-by: David S.

2018-07-29selftests: mlxsw: qos_dscp_bridge: FixPetr Machata
There are two problems in this test case: - When indexing in bash associative array, the subscript is interpreted as string, not as a variable name to be expanded. - The keys stored to t0s and t1s are not DSCP values, but priority + base (i.e. the logical DSCP value, not the full bitfield value). In combination these two bugs conspire to make the test just work, except it doesn't really test anything and always passes. Fix the above two problems in obvious manner.
