2024-08-10ALSA: timer: Relax start tick time check for slave timer elementsTakashi Iwai1-1/+1
The recent addition of a sanity check for a too low start tick time seems breaking some applications that uses aloop with a certain slave timer setup. They may have the initial resolution 0, hence it's treated as if it were a too low value. Relax and skip the check for the slave timer instance for addressing the regression.

2024-08-10irqchip/riscv-aplic: Retrigger MSI interrupt on source configurationYong-Xuan Wang1-7/+25
The section 4.5.2 of the RISC-V AIA specification says that "any write to a sourcecfg register of an APLIC might (or might not) cause the corresponding interrupt-pending bit to be set to one if the rectified input value is high (= 1) under the new source mode." When the interrupt type is changed in the sourcecfg register, the APLIC device might not set the corresponding pending bit, so the interrupt might never become pending. To handle sourcecfg register changes for level-triggered interrupts in MSI mode, manually set the pending bit for retriggering interrupt so it gets retriggered if it was already asserted.

2024-08-10irqchip/xilinx: Fix shift out of boundsRadhey Shyam Pandey1-1/+1
The device tree property 'xlnx,kind-of-intr' is sanity checked that the bitmask contains only set bits which are in the range of the number of interrupts supported by the controller. The check is done by shifting the mask right by the number of supported interrupts and checking the result for zero. The data type of the mask is u32 and the number of supported interrupts is up to 32. In case of 32 interrupts the shift is out of bounds, resulting in a mismatch warning. The out of bounds condition is also reported by UBSAN: UBSAN: shift-out-of-bounds in irq-xilinx-intc.c:332:22 shift exponent 32 is too large for 32-bit type 'unsigned int' Fix it by promoting the mask to u64 for the test.

2024-08-09net/mlx5e: Correctly report errors for ethtool rx flowsCosmin Ratiu1-1/+1
Previously, an ethtool rx flow with no attrs would not be added to the NIC as it has no rules to configure the hw with, but it would be reported as successful to the caller (return code 0). This is confusing for the user as ethtool then reports "Added rule $num", but no rule was actually added. This change corrects that by instead reporting these wrong rules as -EINVAL.

2024-08-09net/mlx5e: SHAMPO, Increase timeout to improve latencyDragos Tatulea4-14/+17
During latency tests (netperf TCP_RR) a 30% degradation of HW GRO vs SW GRO was observed. This is due to SHAMPO triggering timeout filler CQEs instead of delivering the CQE for the packet. Having a short timeout for SHAMPO doesn't bring any benefits as it is the driver that does the merging, not the hardware. On the contrary, it can have a negative impact: additional filler CQEs are generated due to the timeout. As there is no way to disable this timeout, this change sets it to the maximum value. Instead of using the packet_merge.timeout parameter which is also used for LRO, set the value directly when filling in the rest of the SHAMPO parameters in mlx5e_build_rq_param().

2024-08-09udp: Fall back to software USO if IPv6 extension headers are presentJakub Sitnicki1-0/+6
In commit 10154dbded6d ("udp: Allow GSO transmit from devices with no checksum offload") we have intentionally allowed UDP GSO packets marked CHECKSUM_NONE to pass to the GSO stack, so that they can be segmented and checksummed by a software fallback when the egress device lacks these features. What was not taken into consideration is that a CHECKSUM_NONE skb can be handed over to the GSO stack also when the egress device advertises the tx-udp-segmentation / NETIF_F_GSO_UDP_L4 feature. This will happen when there are IPv6 extension headers present, which we check for in __ip6_append_data(). Syzbot has discovered this scenario, producing a warning as below: ip6tnl0: caps=(0x00000006401d7869, 0x00000006401d7869) WARNING: CPU: 0 PID: 5112 at net/core/dev.c:3293 skb_warn_bad_offload+0x166/0x1a0 net/core/dev.c:3291 Modules linked in: CPU: 0 PID: 5112 Comm: syz-executor391 Not tainted 6.10.0-rc7-syzkaller-01603-g80ab5445da62 #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 06/07/2024 RIP: 0010:skb_warn_bad_offload+0x166/0x1a0 net/core/dev.c:3291 [...] Call Trace: <TASK> __skb_gso_segment+0x3be/0x4c0 net/core/gso.c:127 skb_gso_segment include/net/gso.h:83 [inline] validate_xmit_skb+0x585/0x1120 net/core/dev.c:3661 __dev_queue_xmit+0x17a4/0x3e90 net/core/dev.c:4415 neigh_output include/net/neighbour.h:542 [inline] ip6_finish_output2+0xffa/0x1680 net/ipv6/ip6_output.c:137 ip6_finish_output+0x41e/0x810 net/ipv6/ip6_output.c:222 ip6_send_skb+0x112/0x230 net/ipv6/ip6_output.c:1958 udp_v6_send_skb+0xbf5/0x1870 net/ipv6/udp.c:1292 udpv6_sendmsg+0x23b3/0x3270 net/ipv6/udp.c:1588 sock_sendmsg_nosec net/socket.c:730 [inline] __sock_sendmsg+0xef/0x270 net/socket.c:745 ____sys_sendmsg+0x525/0x7d0 net/socket.c:2585 ___sys_sendmsg net/socket.c:2639 [inline] __sys_sendmmsg+0x3b2/0x740 net/socket.c:2725 __do_sys_sendmmsg net/socket.c:2754 [inline] __se_sys_sendmmsg net/socket.c:2751 [inline] __x64_sys_sendmmsg+0xa0/0xb0 net/socket.c:2751 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xf3/0x230 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x77/0x7f [...] </TASK> We are hitting the bad offload warning because when an egress device is capable of handling segmentation offload requested by skb_shinfo(skb)->gso_type, the chain of gso_segment callbacks won't produce any segment skbs and return NULL.

2024-08-09net: Make USO depend on CSUM offloadJakub Sitnicki1-9/+17
UDP segmentation offload inherently depends on checksum offload. It should not be possible to disable checksum offload while leaving USO enabled. Enforce this dependency in code. There is a single tx-udp-segmentation feature flag to indicate support for both IPv4/6, hence the devices wishing to support USO must offer checksum offload for both IP versions.

2024-08-09binfmt_flat: Fix corruption when not offsetting data startKees Cook1-1/+3
Commit 04d82a6d0881 ("binfmt_flat: allow not offsetting data start") introduced a RISC-V specific variant of the FLAT format which does not allocate any space for the (obsolete) array of shared library pointers. However, it did not disable the code which initializes the array, resulting in the corruption of sizeof(long) bytes before the DATA segment, generally the end of the TEXT segment. Introduce MAX_SHARED_LIBS_UPDATE which depends on the state of CONFIG_BINFMT_FLAT_NO_DATA_START_OFFSET to guard the initialization of the shared library pointer region so that it will only be initialized if space is reserved for it.

2024-08-10rust: x86: remove `-3dnow{,a}` from target featuresMiguel Ojeda1-2/+2
LLVM 19 is dropping support for 3DNow! in commit f0eb5587ceeb ("Remove support for 3DNow!, both intrinsics and builtins. (#96246)"): Remove support for 3DNow!, both intrinsics and builtins. (#96246) This set of instructions was only supported by AMD chips starting in the K6-2 (introduced 1998), and before the "Bulldozer" family (2011). They were never much used, as they were effectively superseded by the more-widely-implemented SSE (first implemented on the AMD side in Athlon XP in 2001). This is being done as a predecessor towards general removal of MMX register usage. Since there is almost no usage of the 3DNow! intrinsics, and no modern hardware even implements them, simple removal seems like the best option. Thus we should avoid passing these to the backend, since otherwise we get a diagnostic about it: '-3dnow' is not a recognized feature for this target (ignoring feature) '-3dnowa' is not a recognized feature for this target (ignoring feature) We could try to disable them only up to LLVM 19 (not the C side one, but the one used by `rustc`, which may be built with a range of LLVMs). However, to avoid more complexity, we can likely just remove them altogether. According to Nikita [2]: > I don't think it's needed because LLVM should not generate 3dnow > instructions unless specifically asked to, using intrinsics that > Rust does not provide in the first place. Thus do so, like Rust did for one of their builtin targets [3]. For those curious: Clang will warn only about trying to enable them (`-m3dnow{,a}`), but not about disabling them (`-mno-3dnow{,a}`), so there is no change needed there.

When calling the `rust_is_available.sh` script, we need to make the jobserver available to it, as commit ecab4115c44c ("kbuild: mark `rustc` (and others) invocations as recursive") explains and did for the others. Otherwise, we get a warning from `rustc` when calling `make rust-analyzer` with parallel jobs, e.g. `-j8`. Using several jobs for that target does not really matter, but developers may call `make` with jobs enabled in all cases. Thus fix it.

2024-08-10kbuild: rust: skip -fmin-function-alignment in bindgen flagsZehui Xu1-1/+1
GCC 14 recently added -fmin-function-alignment option and the root Makefile uses it to replace -falign-functions when available. However, this flag can cause issues when passed to the Rust Makefile and affect the bindgen process. Bindgen relies on libclang to parse C code, and currently does not support the -fmin-function-alignment flag, leading to compilation failures when GCC 14 is used. This patch addresses the issue by adding -fmin-function-alignment to the bindgen_skip_c_flags in rust/Makefile. This prevents the flag from causing compilation issues.

What would happen is the following: When ring_buffer_read_page() returns -1 (no data) then a check is made to see if the buffer is empty (as happens when the page is not full), it will call wait_on_pipe() to wait until the ring buffer has data. When it is it will try again to read data (unless O_NONBLOCK is set). The issue happens when there's a reader and the file descriptor is closed. The wait_on_pipe() will return when that is the case. But this loop will continue to try again and wait_on_pipe() will again return immediately and the loop will continue and never stop. Simply check if the file was closed before looping and exit out if it is.

2024-08-09module: make waiting for a concurrent module loader interruptibleLinus Torvalds1-15/+25
The recursive aes-arm-bs module load situation reported by Russell King is getting fixed in the crypto layer, but this in the meantime fixes the "recursive load hangs forever" by just making the waiting for the first module load be interruptible. This should now match the old behavior before commit 9b9879fc0327 ("modules: catch concurrent module loads, treat them as idempotent"), which used the different "wait for module to be ready" code in module_patient_check_exists(). End result: a recursive module load will still block, but now a signal will interrupt it and fail the second module load, at which point the first module will successfully complete loading.

2024-08-09usbnet: ipheth: fix carrier detection in modes 1 and 4Foster Snowhill1-2/+3
Apart from the standard "configurations", "interfaces" and "alternate interface settings" in USB, iOS devices also have a notion of "modes". In different modes, the device exposes a different set of available configurations. Depending on the iOS version, and depending on the current mode, the length and contents of the carrier state control message differs: * 1 byte (seen on iOS 4.2.1, 8.4): * 03: carrier off (mode 0) * 04: carrier on (mode 0) * 3 bytes (seen on iOS 10.3.4, 15.7.6): * 03 03 03: carrier off (mode 0) * 04 04 03: carrier on (mode 0) * 4 bytes (seen on iOS 16.5, 17.6): * 03 03 03 00: carrier off (mode 0) * 04 03 03 00: carrier off (mode 1) * 06 03 03 00: carrier off (mode 4) * 04 04 03 04: carrier on (mode 0 and 1) * 06 04 03 04: carrier on (mode 4) Before this change, the driver always used the first byte of the response to determine carrier state. From this larger sample, the first byte seems to indicate the number of available USB configurations in the current mode (with the exception of the default mode 0), and in some cases (namely mode 1 and 4) does not correlate with the carrier state. Previous logic erroneously counted `04 03 03 00` as "carrier on" and `06 04 03 04` as "carrier off" on iOS versions that support mode 1 and mode 4 respectively. Only modes 0, 1 and 4 expose the USB Ethernet interfaces necessary for the ipheth driver. Check the second byte of the control message where possible, and fall back to checking the first byte on older iOS versions.

2024-08-09usbnet: ipheth: do not stop RX on failing RX callbackFoster Snowhill1-1/+0
RX callbacks can fail for multiple reasons: * Payload too short * Payload formatted incorrecly (e.g. bad NCM framing) * Lack of memory None of these should cause the driver to seize up. Make such failures non-critical and continue processing further incoming URBs. Signed-off-by: Foster Snowhill <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2024-08-09usbnet: ipheth: drop RX URBs with no payloadFoster Snowhill1-0/+6
On iPhone 15 Pro Max one can observe periodic URBs with no payload on the "bulk in" (RX) endpoint. These don't seem to do anything meaningful. Reproduced on iOS 17.5.1 and 17.6. This behaviour isn't observed on iPhone 11 on the same iOS version. The nature of these zero-length URBs is so far unknown. Drop RX URBs with no payload.

2024-08-09usbnet: ipheth: remove extraneous rx URB length checkFoster Snowhill1-6/+2
Rx URB length was already checked in ipheth_rcvbulk_callback_legacy() and ipheth_rcvbulk_callback_ncm(), depending on the current mode. The check in ipheth_rcvbulk_callback() was thus mostly a duplicate. The only place in ipheth_rcvbulk_callback() where we care about the URB length is for the initial control frame. These frames are always 4 bytes long. This has been checked as far back as iOS 4.2.1 on iPhone 3G. Remove the extraneous URB length check. For control frames, check for the specific 4-byte length instead. Signed-off-by: Foster Snowhill <[email protected]> Tested-by: Georgi Valkov <[email protected]> Signed-off-by: David S.

2024-08-09usbnet: ipheth: race between ipheth_close and error handlingOliver Neukum1-1/+1
ipheth_sndbulk_callback() can submit carrier_work as a part of its error handling. That means that the driver must make sure that the work is cancelled after it has made sure that no more URB can terminate with an error condition. Hence the order of actions in ipheth_close() needs to be inverted.
