[ Upstream commit fdddc65a ] Current implementation does not guarantee packed pixel modes working with every dongle. There are some dongles, which require selecting the output mode explicitly. Write proper values to registers in packed_pixel mode, based on how it is done in vendor's code. Select output color space: RGB (no packed pixel) or YCBCR422 (packed pixel). This reverts commit e8b92efa ("drm/bridge/sii8620: fix display of packed pixel modes in MHL2"). Signed-off-by:

[ Upstream commit 1e8e18f6 ] There is a special case that the size is "(N << KASAN_SHADOW_SCALE_SHIFT) Pages plus X", the value of X is [1, KASAN_SHADOW_SCALE_SIZE-1]. The operation "size >> KASAN_SHADOW_SCALE_SHIFT" will drop X, and the roundup operation can not retrieve the missed one page. For example: size=0x28006, PAGE_SIZE=0x1000, KASAN_SHADOW_SCALE_SHIFT=3, we will get shadow_size=0x5000, but actually we need 6 pages. shadow_size = round_up(size >> KASAN_SHADOW_SCALE_SHIFT, PAGE_SIZE); This can lead to a kernel crash when kasan is enabled and the value of mod->core_layout.size or mod->init_layout.size is like above. Because the shadow memory of X has not been allocated and mapped. move_module: ptr = module_alloc(mod->core_layout.size); ... memset(ptr, 0, mod->core_layout.size); //crashed Unable to handle kernel paging request at virtual address ffff0fffff97b000 ......

[ Upstream commit 3b8d5735 ] The touch sensors on the 2nd-gen Intuos tablets don't use a 4096x4096 sensor like other similar tablets (3rd-gen Bamboo, Intuos5, etc.). The incorrect maximum XY values don't normally affect userspace since touch input from these devices is typically relative rather than absolute. It does, however, cause problems when absolute distances need to be measured, e.g. for gesture recognition. Since the resolution of the touch sensor on these devices is 10 units / mm (versus 100 for the pen sensor), the proper maximum values can be calculated by simply dividing by 10.

[ Upstream commit 4fb5f58e ] On 32-bit kernels, __flush_tlb_all() may have read the CR4 shadow before the initialization of CR4 shadow in cpu_init(). Fix it by adding an explicit cr4_init_shadow() call into start_secondary() which is the first function called on non-boot SMP CPUs - ahead of the __flush_tlb_all() call. ( This is somewhat of a layering violation, but start_secondary() does CR4 bootstrap in the PCID case anyway. ) Signed-off-by:

[ Upstream commit 5dc2d399 ] After we change the ipvlan mode from l3 to l2, or vice versa, we only reset IFF_NOARP flag, but don't flush the ARP table cache, which will cause eth->h_dest to be equal to eth->h_source in ipvlan_xmit_mode_l2(). Then the message will not come out of host. Here is the reproducer on local host: ip link set eth1 up ip addr add 192.168.1.1/24 dev eth1 ip link add link eth1 ipvlan1 type ipvlan mode l3 ip netns add net1 ip link set ipvlan1 netns net1 ip netns exec net1 ip link set ipvlan1 up ip netns exec net1 ip addr add 192.168.2.1/24 dev ipvlan1 ip route add 192.168.2.0/24 via 192.168.1.2 ping 192.168.2.2 -c 2 ip netns exec net1 ip link set ipvlan1 type ipvlan mode l2 ping 192.168.2.2 -c 2 Add the same configuration on remote host. After we set the mode to l2, we could find that the src/dst MAC addresses are the same on eth1: 21:26:06.648565 00:b7:13:ad:d3:05 > 00:b7:13:ad:d3:05, ethertype IPv4 (0x0800), length 98: (tos 0x0, ttl 64, id 58356, offset 0, flags [DF], proto ICMP (1), length 84) 192.168.2.1 > 192.168.2.2: ICMP echo request, id 22686, seq 1, length 64 Fix this by calling dev_change_flags(), which will call netdevice notifier with flag change info. v2: a) As pointed out by Wang Cong, check return value for dev_change_flags() when change dev flags. b) As suggested by Stefano and Sabrina, move flags setting before l3mdev_ops. So we don't need to redo ipvlan_{, un}register_nf_hook() again in err path. Reported-by:

[ Upstream commit 08b393d0 ] Since the following commit: cd77849a ("objtool: Fix GCC 8 cold subfunction detection for aliased functions") ... if the kernel is built with EXTRA_CFLAGS='-fno-reorder-functions', objtool can get stuck in an infinite loop. That flag causes the new GCC 8 cold subfunctions to be placed in .text instead of .text.unlikely. But it also has an unfortunate quirk: in the symbol table, the subfunction (e.g., nmi_panic.cold.7) is nested inside the parent (nmi_panic). That function overlap confuses objtool, and causes it to get into an infinite loop in next_insn_same_func(). Here's Allan's description of the loop: "Objtool iterates through the instructions in nmi_panic using next_insn_same_func. Once it reaches the end of nmi_panic at 0x534 it jumps to 0x528 as that's the start of nmi_panic.cold.7. However, since the instructions starting at 0x528 are still associated with nmi_panic objtool will get stuck in a loop, continually jumping back to 0x528 after reaching 0x534." Fix it by shortening the length of the parent function so that the functions no longer overlap. Reported-and-analyzed-by:

[ Upstream commit ae15a41a ] Originally in patch e6d20c55 ("openrisc: entry: Fix delay slot detection") I fixed delay slot detection, but only for QEMU. We missed that hardware delay slot detection using delay slot exception flag (DSX) was still broken. This was because QEMU set the DSX flag in both pre-exception supervision register (ESR) and supervision register (SR) register, but on real hardware the DSX flag is only set on the SR register during exceptions. Fix this by carrying the DSX flag into the SR register during exception. We also update the DSX flag read locations to read the value from the SR register not the pt_regs SR register which represents ESR. The ESR should never have the DSX flag set. In the process I updated/removed a few comments to match the current state. Including removing a comment saying that the DSX detection logic was inefficient and needed to be rewritten. I have tested this on QEMU with a patch ensuring it matches the hardware specification.

In such cases OS still see the link, which would result in undesirable functionalities such as re-generation of tx-timeouts. The patch addresses this issue by indicating the link-down to OS when tx-timeout is detected, and keeping the link in down state till the internal reload is successful.

[ Upstream commit 188f60ab ] Commit 9757235f, "nl80211: correct checks for NL80211_MESHCONF_HT_OPMODE value") relaxed the range for the HT operation field in meshconf, while also adding checks requiring the non-greenfield and non-ht-sta bits to be set in certain circumstances. The latter bit is actually reserved for mesh BSSes according to Table 9-168 in 802.11-2016, so in fact it should not be set. wpa_supplicant sets these bits because the mesh and AP code share the same implementation, but authsae does not. As a result, some meshconf updates from authsae which set only the NONHT_MIXED protection bits were being rejected. In order to avoid breaking userspace by changing the rules again, simply accept the values with or without the bits set, and mask off the reserved bit to match the spec. While in here, update the 802.11-2012 reference to 802.11-2016.

[ Upstream commit 9191fc2a ] In the case of Station connects to AP with narrower bandwidth at beginning. And later the AP changes the bandwidth to winder bandwidth, the AP will beacon with wider bandwidth IE, eg VHT20->VHT40->VHT80 or VHT40->VHT80. Since the supported BANDWIDTH will be limited by the PHYMODE, so while Station receives the bandwidth change request, it will also need to reconfigure the PHYMODE setting to firmware instead of just configuring the BANDWIDTH info, otherwise it'll trigger a firmware crash with non-support bandwidth. The issue was observed in WLAN.RM.4.4.1-00051-QCARMSWP-1, QCA6174 with below scenario: AP xxx changed bandwidth, new config is 5200 MHz, width 2 (5190/0 MHz) disconnect from AP xxx for new auth to yyy RX ReassocResp from xxx (capab=0x1111 status=0 aid=102) associated ....

[ Upstream commit ec348020 ] When I wrote the sigreturn test, I didn't realize that AMD's busted IRET behavior was different from Intel's busted IRET behavior: On AMD CPUs, the CPU leaks the high 32 bits of the kernel stack pointer to certain userspace contexts. Gee, thanks. There's very little the kernel can do about it. Modify the test so it passes. Signed-off-by:

[ Upstream commit a8d70a05 ] In smartnic env, if the host (PF) driver is not an e-switch manager, we are not allowed to apply eswitch ports setups such as vlan (VST), spoof-checks, min/max rate or state. Make sure we are eswitch manager when coming to issue these callbacks and err otherwise. Also fix the definition of ESW_ALLOWED to rely on eswitch_manager capability and on the vport_group_manger. Operations on the VF nic vport context, such as setting a mac or reading the vport counters are allowed to the PF in this scheme. The modify nic vport guid code was modified to omit checking the nic_vport_node_guid_modify eswitch capability. The reason for doing so is that modifying node guid requires vport group manager capability, and there's no need to check further capabilities. 1. set_vf_vlan - disallowed 2. set_vf_spoofchk - disallowed 3. set_vf_mac - allowed 4. get_vf_config - allowed 5. set_vf_trust - disallowed 6. set_vf_rate - disallowed 7. get_vf_stat - allowed 8. set_vf_link_state - disallowed Fixes: f942380c ('net/mlx5: E-Switch, Vport ingress/egress ACLs rules for spoofchk') Signed-off-by:
