commit 5f2779d upstream. The behavior of 'enum' types has changed in gcc-13, so now the UNBUSY_THR_PCT constant is interpreted as a 64-bit number because it is defined as part of the same enum definition as some other constants that do not fit within a 32-bit integer. This in turn leads to some inefficient code on 32-bit architectures as well as a link error: arm-linux-gnueabi/bin/arm-linux-gnueabi-ld: block/blk-iocost.o: in function `ioc_timer_fn': blk-iocost.c:(.text+0x68e8): undefined reference to `__aeabi_uldivmod' arm-linux-gnueabi-ld: blk-iocost.c:(.text+0x6908): undefined reference to `__aeabi_uldivmod' Split the enum definition to keep the 64-bit timing constants in a separate enum type from those constants that can clearly fit within a smaller type.

commit ff1cc97 upstream. Since gcc13, each member of an enum has the same type as the enum [1]. And that is inherited from its members. Provided: VTIME_PER_SEC_SHIFT = 37, VTIME_PER_SEC = 1LLU << VTIME_PER_SEC_SHIFT, ... AUTOP_CYCLE_NSEC = 10LLU * NSEC_PER_SEC, the named type is unsigned long. This generates warnings with gcc-13: block/blk-iocost.c: In function 'ioc_weight_prfill': block/blk-iocost.c:3037:37: error: format '%u' expects argument of type 'unsigned int', but argument 4 has type 'long unsigned int' block/blk-iocost.c: In function 'ioc_weight_show': block/blk-iocost.c:3047:34: error: format '%u' expects argument of type 'unsigned int', but argument 3 has type 'long unsigned int' So split the anonymous enum with large values to a separate enum, so that they don't affect other members.

Not upstream as this function is no longer around anymore. The function i40iw_manage_apbvt() has the wrong prototype match from the .h file to the .c declaration, so fix it up, otherwise gcc-13 complains (rightfully) that the type is incorrect. Signed-off-by: Greg Kroah-Hartman <[email protected]>

[ Upstream commit 0c331fd ] It is usually better to request all necessary resources (clocks, regulators, ...) before starting to make use of them. That way they do not change state in case one of the resources is not available yet and probe deferral (-EPROBE_DEFER) is necessary. This is particularly important for DMA channels and IOMMUs which are not enforced by fw_devlink yet (unless you use fw_devlink.strict=1). spi-qup does this in the wrong order, the clocks are enabled and disabled again when the DMA channels are not available yet. This causes issues in some cases: On most SoCs one of the SPI QUP clocks is shared with the UART controller. When using earlycon UART is actively used during boot but might not have probed yet, usually for the same reason (waiting for the DMA controller). In this case, the brief enable/disable cycle ends up gating the clock and further UART console output will halt the system completely. Avoid this by requesting the DMA channels before changing the clock state.

[ Upstream commit a27648c ] kafs incorrectly passes a zero mtime (ie. 1st Jan 1970) to the server when creating a file, dir or symlink because the mtime recorded in the afs_operation struct gets passed to the server by the marshalling routines, but the afs_mkdir(), afs_create() and afs_symlink() functions don't set it. This gets masked if a file or directory is subsequently modified. Fix this by filling in op->mtime before calling the create op.

[ Upstream commit 02c5ea5 ] L2CAP assumes that the locks conn->chan_lock and chan->lock are acquired in the order conn->chan_lock, chan->lock to avoid potential deadlock. For example, l2sock_shutdown acquires these locks in the order: mutex_lock(&conn->chan_lock) l2cap_chan_lock(chan) However, l2cap_disconnect_req acquires chan->lock in l2cap_get_chan_by_scid first and then acquires conn->chan_lock before calling l2cap_chan_del. This means that these locks are acquired in unexpected order, which leads to potential deadlock: l2cap_chan_lock(c) mutex_lock(&conn->chan_lock) This patch releases chan->lock before acquiring the conn_chan_lock to avoid the potential deadlock.

[ Upstream commit 24e2278 ] syzkaller found a repro that causes Hung Task [0] with ipset. The repro first creates an ipset and then tries to delete a large number of IPs from the ipset concurrently: IPSET_ATTR_IPADDR_IPV4 : 172.20.20.187 IPSET_ATTR_CIDR : 2 The first deleting thread hogs a CPU with nfnl_lock(NFNL_SUBSYS_IPSET) held, and other threads wait for it to be released. Previously, the same issue existed in set->variant->uadt() that could run so long under ip_set_lock(set). Commit 5e29dc3 ("netfilter: ipset: Rework long task execution when adding/deleting entries") tried to fix it, but the issue still exists in the caller with another mutex. While adding/deleting many IPs, we should release the CPU periodically to prevent someone from abusing ipset to hang the system. Note we need to increment the ipset's refcnt to prevent the ipset from being destroyed while rescheduling. [0]: INFO: task syz-executor174:268 blocked for more than 143 seconds.

[ Upstream commit a2f4c14 ] A remote DoS vulnerability of RPL Source Routing is assigned CVE-2023-2156. The Source Routing Header (SRH) has the following format: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Next Header | Hdr Ext Len | Routing Type | Segments Left | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | CmprI | CmprE | Pad | Reserved | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | . . . Addresses[1..n] . . . | | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ The originator of an SRH places the first hop's IPv6 address in the IPv6 header's IPv6 Destination Address and the second hop's IPv6 address as the first address in Addresses[1..n]. The CmprI and CmprE fields indicate the number of prefix octets that are shared with the IPv6 Destination Address. When CmprI or CmprE is not 0, Addresses[1..n] are compressed as follows: 1..n-1 : (16 - CmprI) bytes n : (16 - CmprE) bytes Segments Left indicates the number of route segments remaining. When the value is not zero, the SRH is forwarded to the next hop. Its address is extracted from Addresses[n - Segment Left + 1] and swapped with IPv6 Destination Address. When Segment Left is greater than or equal to 2, the size of SRH is not changed because Addresses[1..n-1] are decompressed and recompressed with CmprI. OTOH, when Segment Left changes from 1 to 0, the new SRH could have a different size because Addresses[1..n-1] are decompressed with CmprI and recompressed with CmprE. Let's say CmprI is 15 and CmprE is 0. When we receive SRH with Segment Left >= 2, Addresses[1..n-1] have 1 byte for each, and Addresses[n] has 16 bytes. When Segment Left is 1, Addresses[1..n-1] is decompressed to 16 bytes and not recompressed. Finally, the new SRH will need more room in the header, and the size is (16 - 1) * (n - 1) bytes. Here the max value of n is 255 as Segment Left is u8, so in the worst case, we have to allocate 3825 bytes in the skb headroom. However, now we only allocate a small fixed buffer that is IPV6_RPL_SRH_WORST_SWAP_SIZE (16 + 7 bytes). If the decompressed size overflows the room, skb_push() hits BUG() below [0]. Instead of allocating the fixed buffer for every packet, let's allocate enough headroom only when we receive SRH with Segment Left 1.

[ Upstream commit 1d99780 ] Only older NIC controller's firmware uses the PROC AP reset type. Firmware on 5731X/5741X and newer chips does not support this reset type.

[ Upstream commit 1a9e4f5 ] We need to call bnxt_hwrm_func_qcfg() on a VF to query the default VLAN that may be setup by the PF. If a default VLAN is enabled, the VF cannot support VLAN acceleration on the receive side and the VNIC must be setup to strip out the default VLAN tag. If a default VLAN is not enabled, the VF can support VLAN acceleration on the receive side. The VNIC should be set up to strip or not strip the VLAN based on the RX VLAN acceleration setting. Without this call to determine the default VLAN before calling bnxt_setup_vnic(), the VNIC may not be set up correctly. For example, bnxt_setup_vnic() may set up to strip the VLAN tag based on stale default VLAN information. If RX VLAN acceleration is not enabled, the VLAN tag will be incorrectly stripped and the RX data path will not work correctly.

[ Upstream commit 1eb4ef1 ] As per the new udp tunnel framework, drivers which need to know the details of a port entry (i.e. port type) when it gets deleted should use the .set_port / .unset_port callbacks. Implementing the current .udp_tunnel_sync callback would mean that the deleted tunnel port entry would be all zeros. This used to work on older firmware because it would not check the input when deleting a tunnel port. With newer firmware, the delete will now fail and subsequent tunnel port allocation will fail as a result.

commit abac3ac upstream. Syzkaller got a lot of crashes like: KASAN: use-after-free Write in *_timers* All of these crashes point to the same memory area: The buggy address belongs to the object at ffff88801f870000 which belongs to the cache kmalloc-8k of size 8192 The buggy address is located 5320 bytes inside of 8192-byte region [ffff88801f870000, ffff88801f872000) This area belongs to : batadv_priv->batadv_priv_dat->delayed_work->timer_list The reason for these issues is the lack of synchronization. Delayed work (batadv_dat_purge) schedules new timer/work while the device is being deleted. As the result new timer/delayed work is set after cancel_delayed_work_sync() was called. So after the device is freed the timer list contains pointer to already freed memory. Found by Linux Verification Center (linuxtesting.org) with syzkaller.

commit feee70f upstream. While doing my research to improve the xpad device names I noticed that the 1532:0037 VID/PID seems to be used by the DeathAdder 2013, so that Razer Sabertooth instance looked wrong and very suspect to me. I didn't see any mention in the official drivers, either. After doing more research, it turns out that the xpad list is used by many other projects (like Steam) as-is [1], this issue was reported [2] and Valve/Sam Lantinga fixed it [3]: [1]: https://github.com/libsdl-org/SDL/blob/dcc5eef0e2395854b254ea2873a4899edab347c6/src/joystick/controller_type.h#L251 [2]: https://steamcommunity.com/app/353380/discussions/0/1743392486228754770/ [3]: https://hg.libsdl.org/SDL/rev/29809f6f0271 (With multiple Internet users reporting similar issues, not linked here) After not being able to find the correct VID/PID combination anywhere on the Internet and not receiving any reply from Razer support I did some additional detective work, it seems like it presents itself as "Razer Sabertooth Gaming Controller (XBOX360)", code 1689:FE00. Leaving us with this: * Razer Sabertooth (1689:fe00) * Razer Sabertooth Elite (24c6:5d04) * Razer DeathAdder 2013 (1532:0037) [note: not a gamepad] So, to sum things up; remove this conflicting/duplicate entry: { 0x1532, 0x0037, "Razer Sabertooth", 0, XTYPE_XBOX360 }, As the real/correct one is already present there, even if the Internet as a whole insists on presenting it as the Razer Sabertooth Elite, which (by all accounts) is not: { 0x1689, 0xfe00, "Razer Sabertooth", 0, XTYPE_XBOX360 }, Actual change in SDL2 referencing this kernel issue: libsdl-org/SDL@e5e5416 For more information of the device, take a look here: xboxdrv/xboxdrv#59 You can see a lsusb dump here: https://github.com/xboxdrv/xboxdrv/files/76581/Qa6dBcrv.txt Fixes: f554f61 ("Input: xpad - sync device IDs with xboxdrv") Signed-off-by: Ismael Ferreras Morezuelas <[email protected]> Reviewed-by: Cameron Gutman <[email protected]> Cc: [email protected] Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Dmitry Torokhov <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

…phys [ Upstream commit 85d38d5 ] When booting with "intremap=off" and "x2apic_phys" on the kernel command line, the physical x2APIC driver ends up being used even when x2APIC mode is disabled ("intremap=off" disables x2APIC mode). This happens because the first compound condition check in x2apic_phys_probe() is false due to x2apic_mode == 0 and so the following one returns true after default_acpi_madt_oem_check() having already selected the physical x2APIC driver.

[ Upstream commit 9724160 ] When building a kernel with LLVM=1, LLVM_IAS=0 and CONFIG_KASAN=y, LLVM leaves DWARF tags for the "asan.module_ctor" & co symbols. In turn, pahole creates BTF_KIND_FUNC entries for these and this makes the BTF metadata validation fail because they contain a dot. In a dramatic turn of event, this BTF verification failure can cause the netfilter_bpf initialization to fail, causing netfilter_core to free the netfilter_helper hashmap and netfilter_ftp to trigger a use-after-free. The risk of u-a-f in netfilter will be addressed separately but the existence of "asan.module_ctor" debug info under some build conditions sounds like a good enough reason to accept functions that contain dots in BTF. Although using only LLVM=1 is the recommended way to compile clang-based kernels, users can certainly do LLVM=1, LLVM_IAS=0 as well and we still try to support that combination according to Nick. To clarify: - > v5.10 kernel, LLVM=1 (LLVM_IAS=0 is not the default) is recommended, but user can still have LLVM=1, LLVM_IAS=0 to trigger the issue - <= 5.10 kernel, LLVM=1 (LLVM_IAS=0 is the default) is recommended in which case GNU as will be used Fixes: 1dc9285 ("bpf: kernel side support for BTF Var and DataSec") Signed-off-by: Florent Revest <[email protected]> Signed-off-by: Daniel Borkmann <[email protected]> Acked-by: Andrii Nakryiko <[email protected]> Cc: Yonghong Song <[email protected]> Cc: Nick Desaulniers <[email protected]> Link: https://lore.kernel.org/bpf/[email protected] Signed-off-by: Sasha Levin <[email protected]>

This particular patch was taken from: https://gitlab.com/Queuecumber/linux-acs-override/-/blob/master/workspaces/5.4/acso.patch The only change I made is that we skip checking for devices with ACS Caps in pcie_acs_overrides(), since the PCI port may not support Upstream Forward, and might still support other capabilties, thus might return true while checking for PCI_EXT_CAP_ID_ACS presence, thus rendering the patch not usable in some platforms.

This simply introduces a tiny LED driver based on the MMIO GPIO registers described in user's manual. It would be nice to find a generic MMIO GPIO driver since it seems like there's a few that do this type of thing already (including the one for APU LEDs that was used as a prototype).
All of this is selectively taken from:
https://github.com/AaeonCM/meta-up-board/tree/warrior/recipes-kernel/linux/files
====================================================================================
Add a function to gpiolib to facilitate registering a pin controller for
a range of GPIO pins, but using ACPI resource references and without
claiming the GPIO resource.
====================================================================================
Add support for chaining pinctrl drivers controlling the same GPIO line.
This allows for hardware configurations where multiple controllers must
to be configured to change the function or electrical properties of the
line.
Such is the case of the UP board family. On these boards, GPIO and other
SoC functions are provided by a 40-pin Raspberry Pi compatible header,
plus custom headers on certain models. However, for added flexibility,
there is a FPGA between the SoC and these physical pins. In its default
configuration, this FPGA implements a pin controller for FPGA-connected
pins. This setup requires coordination between the SoC GPIO controller
and the FPGA-based controller, hence this patch.
====================================================================================
Expose regmap_writable function to check if a register is writable
====================================================================================
The UP Squared board <http://www.upboard.com> implements certain
features (pin control, onboard LEDs or CEC) through an on-board FPGA.
This mfd driver implements the line protocol to read and write registers
from the FPGA through regmap. The register address map is also included.
The UP boards come with a few FPGA-controlled onboard LEDs:
* UP Board: yellow, green, red
* UP Squared: blue, yellow, green, red
The UP Boards provide a few I/O pin headers (for both GPIO and
functions), including a 40-pin Raspberry Pi compatible header.
This patch implements support for the FPGA-based pin controller that
manages direction and enable state for those header pins.
