The VSC73xx has a busy flag used during MDIO operations. It is raised when MDIO read/write operations are in progress. Without it, PHYs are misconfigured and bus operations do not work as expected. Fixes: 05bd97fc ("net: dsa: Add Vitesse VSC73xx DSA router driver") Reviewed-by:

According to the datasheet description ("Port Mode Procedure" in 5.6.2), the VSC73XX_MAC_CFG_WEXC_DIS bit is configured only for half duplex mode. The WEXC_DIS bit is responsible for MAC behavior after an excessive collision. Let's set it as described in the datasheet.

`ip_hdr(skb)->ihl << 2` is the same as `ip_hdrlen(skb)` Therefore, we should use a well-defined function not a bit shift to find the header length. It also compresses two lines to a single line. Signed-off-by:

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.

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().

Jakub Sitnicki says: ==================== Don't take HW USO path when packets can't be checksummed by device This series addresses a recent regression report from syzbot [1]. After enabling UDP_SEGMENT for egress devices which don't support checksum offload [2], we need to tighten down the checks which let packets take the HW USO path. The fix consists of two parts: 1. don't let devices offer USO without checksum offload, and 2. force software USO fallback in presence of IPv6 extension headers.

In commit 10154dbd ("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-g80ab5445 #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.

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.

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. Signed-off-by:Foster Snowhill <forst@pen.gy> Tested-by:

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:

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. Signed-off-by:

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:

Oliver Neukum authored
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. Signed-off-by:

Pull tracing fixes from Steven Rostedt: - Have reading of event format files test if the metadata still exists. When a event is freed, a flag (EVENT_FILE_FL_FREED) in the metadata is set to state that it is to prevent any new references to it from happening while waiting for existing references to close. When the last reference closes, the metadata is freed. But the "format" was missing a check to this flag (along with some other files) that allowed new references to happen, and a use-after-free bug to occur. - Have the trace event meta data use the refcount infrastructure instead of relying on its own atomic counters. - Have tracefs inodes use alloc_inode_sb() for allocation instead of using kmem_cache_alloc() directly. - Have eventfs_create_dir() return an ERR_PTR instead of NULL as the callers expect a real object or an ERR_PTR. - Have release_ei() use call_srcu() and not call_rcu() as all the protection is on SRCU and not RCU. - Fix ftrace_graph_ret_addr() to use the task passed in and not current. - Fix overflow bug in get_free_elt() where the counter can overflow the integer and cause an infinite loop. - Remove unused function ring_buffer_nr_pages() - Have tracefs freeing use the inode RCU infrastructure instead of creating its own. When the kernel had randomize structure fields enabled, the rcu field of the tracefs_inode was overlapping the rcu field of the inode structure, and corrupting it. Instead, use the destroy_inode() callback to do the initial cleanup of the code, and then have free_inode() free it. * tag 'trace-v6.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracefs: Use generic inode RCU for synchronizing freeing ring-buffer: Remove unused function ring_buffer_nr_pages() tracing: Fix overflow in get_free_elt() function_graph: Fix the ret_stack used by ftrace_graph_ret_addr() eventfs: Use SRCU for freeing eventfs_inodes eventfs: Don't return NULL in eventfs_create_dir() tracefs: Fix inode allocation tracing: Use refcount for trace_event_file reference counter tracing: Have format file honor EVENT_FILE_FL_FREED

Russell King reported that the arm cbc(aes) crypto module hangs when loaded, and Herbert Xu bisected it to commit 9b9879fc ("modules: catch concurrent module loads, treat them as idempotent"), and noted: "So what's happening here is that the first modprobe tries to load a fallback CBC implementation, in doing so it triggers a load of the exact same module due to module aliases. IOW we're loading aes-arm-bs which provides cbc(aes). However, this needs a fallback of cbc(aes) to operate, which is made out of the generic cbc module + any implementation of aes, or ecb(aes). The latter happens to also be provided by aes-arm-cb so that's why it tries to load the same module again" So loading the aes-arm-bs module ends up wanting to recursively load itself, and the recursive load then ends up waiting for the original module load to complete. This is a regression, in that it used to be that we just tried to load the module multiple times, and then as we went on to install it the second time we would instead just error out because the module name already existed. That is actually also exactly what the original "catch concurrent loads" patch did in commit 9828ed3f ("module: error out early on concurrent load of the same module file"), but it turns out that it ends up being racy, in that erroring out before the module has been fully initialized will cause failures in dependent module loading. See commit ac2263b5 (which was the revert of that "error out early") commit for details about why erroring out before the module has been initialized is actually fundamentally racy. Now, for the actual recursive module load (as opposed to just concurrently loading the same module twice), the race is not an issue. At the same time it's hard for the kernel to see that this is recursion, because the module load is always done from a usermode helper, so the recursion is not some simple callchain within the kernel. End result: this is not the real fix, but this at least adds a warning for the situation (admittedly much too late for all the debugging pain that Russell and Herbert went through) and if we can come to a resolution on how to detect the recursion properly, this re-organizes the code to make that easier.

As noted in the device errata [1-8], EEE support is not fully operational in the KSZ8567, KSZ9477, KSZ9567, KSZ9896, and KSZ9897 devices, causing link drops when connected to another device that supports EEE. The patch series "net: add EEE support for KSZ9477 switch family" merged in commit 9b0bf4f7 caused EEE support to be enabled in these devices. A fix for this regression for the KSZ9477 alone was merged in commit 08c6d8ba. This patch extends this fix to the other affected devices.

The 'at least one change' requirement is not applicable for context creation, skip the check in such case. This allows a command such as 'ethtool -X eth0 context new' to work. The command works by mistake when using older versions of userspace ethtool due to an incompatibility issue where rxfh.input_xfrm is passed as zero (unset) instead of RXH_XFRM_NO_CHANGE as done with recent userspace. This patch does not try to solve the incompatibility issue.

Both ethtool_ops.rxfh_max_context_id and the default value used when it's not specified are supposed to be exclusive maxima (the former is documented as such; the latter, U32_MAX, cannot be used as an ID since it equals ETH_RXFH_CONTEXT_ALLOC), but xa_alloc() expects an inclusive maximum. Subtract one from 'limit' to produce an inclusive maximum, and pass that to xa_alloc(). Increase bnxt's max by one to prevent a (very minor) regression, as BNXT_MAX_ETH_RSS_CTX is an inclusive max. This is safe since bnxt is not actually hard-limited; BNXT_MAX_ETH_RSS_CTX is just a leftover from old driver code that managed context IDs itself. Rename rxfh_max_context_id to rxfh_max_num_contexts to make its semantics (hopefully) more obvious. Fixes: 847a8ab1 ("net: ethtool: let the core choose RSS context IDs") Signed-off-by:

When l2tp tunnels use a socket provided by userspace, we can hit lockdep splats like the below when data is transmitted through another (unrelated) userspace socket which then gets routed over l2tp. This issue was previously discussed here: https://lore.kernel.org/netdev/87sfialu2n.fsf@cloudflare.com/ The solution is to have lockdep treat socket locks of l2tp tunnel sockets separately than those of standard INET sockets.

dwmac4 was decoding the duplex mode from the GMAC_PHYIF_CONTROL_STATUS register incorrectly, using GMAC_PHYIF_CTRLSTATUS_LNKMOD_MASK (value 1) rather than GMAC_PHYIF_CTRLSTATUS_LNKMOD (bit 16). Fix this. Fixes: 70523e63 ("drivers: net: stmmac: reworking the PCS code.") Reviewed-by:

Tony Nguyen says: ==================== idpf: fix 3 bugs revealed by the Chapter I Alexander Lobakin says: The libeth conversion revealed 2 serious issues which lead to sporadic crashes or WARNs under certain configurations. Additional one was found while debugging these two with kmemleak. This one is targeted stable, the rest can be backported manually later if needed. They can be reproduced only after the conversion is applied anyway. ==================== Link: https://patch.msgid.link/20240806220923.3359860-1-anthony.l.nguyen@intel.comSigned-off-by:
