2024-12-07headers/cleanup.h: Remove the if_not_guard() facilityIngo Molnar
Linus noticed that the new if_not_guard() definition is fragile: "This macro generates actively wrong code if it happens to be inside an if-statement or a loop without a block. IOW, code like this: for (iterate-over-something) if_not_guard(a) return -BUSY; looks like will build fine, but will generate completely incorrect code." The reason is that the __if_not_guard() macro is multi-statement, so while most kernel developers expect macros to be simple or at least compound statements - but for __if_not_guard() it is not so: #define __if_not_guard(_name, _id, args...) \ BUILD_BUG_ON(!__is_cond_ptr(_name)); \ CLASS(_name, _id)(args); \ if (!__guard_ptr(_name)(&_id)) To add insult to injury, the placement of the BUILD_BUG_ON() line makes the macro appear to compile fine, but it will generate incorrect code as Linus reported, for example if used within iteration or conditional statements that will use the first statement of a macro as a loop body or conditional statement body. [ I'd also like to note that the original submission by David Lechner did not contain the BUILD_BUG_ON() line, so it was safer than what we ended up committing. Mea culpa. ] It doesn't appear to be possible to turn this macro into a robust single or compound statement that could be used in single statements, due to the necessity to define an auto scope variable with an open scope and the necessity of it having to expand to a partial 'if' statement with no body. Instead of trying to work around this fragility, just remove the construct before it gets used.

2024-12-06Merge branch 'net-convert-some-udp-tunnel-drivers-to-netdev_pcpu_stat_dstats'Jakub Kicinski
Guillaume Nault says: ==================== net: Convert some UDP tunnel drivers to NETDEV_PCPU_STAT_DSTATS. VXLAN, Geneve and Bareudp use various device counters for managing RX and TX statistics: * VXLAN uses the device core_stats for RX and TX drops, tstats for regular RX/TX counters and DEV_STATS_INC() for various types of RX/TX errors. * Geneve uses tstats for regular RX/TX counters and DEV_STATS_INC() for everything else, include RX/TX drops. * Bareudp, was recently converted to follow VXLAN behaviour, that is, device core_stats for RX and TX drops, tstats for regular RX/TX counters and DEV_STATS_INC() for other counter types. Let's consolidate statistics management around the dstats counters instead. This avoids using core_stats in VXLAN and Bareudp, as core_stats is supposed to be used by core networking code only (and not in drivers). This also allows Geneve to avoid using atomic increments when updating RX and TX drop counters, as dstats is per-cpu. Finally, this also simplifies the code as all three modules now handle stats in the same way and with only two different sets of counters (the per-cpu dstats and the atomic DEV_STATS_INC()). Patch 1 creates dstats helper functions that can be used outside of VRF (until then, dstats was VRF-specific). Then patches 2 to 4, convert VXLAN, Geneve and Bareudp, one by one. ==================== Link: https://patch.msgid.link/cover.1733313925.git.gnault@redhat.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2024-12-06bareudp: Handle stats using NETDEV_PCPU_STAT_DSTATS.Guillaume Nault
Bareudp uses the TSTATS infrastructure (dev_sw_netstats_*()) for RX packet counters. It was also recently converted to use the device core stats (dev_core_stats_*()) for RX and TX drops (see commit 788d5d655bc9 ("bareudp: Use pcpu stats to update rx_dropped counter.")). Since core stats are to be avoided in drivers, and for consistency with VXLAN and Geneve, let's convert packet stats handling to DSTATS, which can handle RX/TX stats and packet drops. Statistics that don't fit DSTATS are still updated atomically with DEV_STATS_INC().

2024-12-06vrf: Make pcpu_dstats update functions available to other modules.Guillaume Nault
Currently vrf is the only module that uses NETDEV_PCPU_STAT_DSTATS. In order to make this kind of statistics available to other modules, we need to define the update functions in netdevice.h. Therefore, let's define dev_dstats_*() functions for RX and TX packet updates (packets, bytes and drops). Use these new functions in vrf.c instead of vrf_rx_stats() and the other manual counter updates. While there, update the type of the "len" variables to "unsigned int", so that there're aligned with both skb->len and the new dstats update functions.

2024-12-06Merge branch 'lan78xx-preparations-for-phylink'Jakub Kicinski
Oleksij Rempel says: ==================== lan78xx: Preparations for PHYlink This patch set is part of the preparatory work for migrating the lan78xx USB Ethernet driver to the PHYlink framework. During extensive testing, I observed that resetting the USB adapter can lead to various read/write errors. While the errors themselves are acceptable, they generate excessive log messages, resulting in significant log spam. This set improves error handling to reduce logging noise by addressing errors directly and returning early when necessary. Key highlights of this series include: - Enhanced error handling to reduce log spam while preserving the original error values, avoiding unnecessary overwrites. - Improved error reporting using the `%pe` specifier for better clarity in log messages. - Removal of redundant and problematic PHY fixups for LAN8835 and KSZ9031, with detailed explanations in the respective patches. - Cleanup of code structure, including unified `goto` labels for better readability and maintainability, even in simple editors. ==================== Link: https://patch.msgid.link/20241204084142.1152696-1-o.rempel@pengutronix.de Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2024-12-06net: usb: lan78xx: Remove KSZ9031 PHY fixupOleksij Rempel
Remove the KSZ9031RNX PHY fixup from the lan78xx driver. The fixup applied specific RGMII pad skew configurations globally, but these settings violate the RGMII specification and cause more harm than benefit. Key issues with the fixup: 1. **Non-Compliant Timing**: The fixup's delay settings fall outside the RGMII specification requirements of 1.5 ns to 2.0 ns: - RX Path: Total delay of **2.16 ns** (PHY internal delay of 1.2 ns + 0.96 ns skew). - TX Path: Total delay of **0.96 ns**, significantly below the RGMII minimum of 1.5 ns. 2. **Redundant or Incorrect Configurations**: - The RGMII skew registers written by the fixup do not meaningfully alter the PHY's default behavior and fail to account for its internal delays. - The TX_DATA pad skew was not configured, relying on power-on defaults that are insufficient for RGMII compliance. 3. **Micrel Driver Support**: By setting `PHY_INTERFACE_MODE_RGMII_ID`, the Micrel driver can calculate and assign appropriate skew values for the KSZ9031 PHY. This ensures better timing configurations without relying on external fixups. 4. **System Interference**: The fixup applied globally, reconfiguring all KSZ9031 PHYs in the system, even those unrelated to the LAN78xx adapter. This could lead to unintended and harmful behavior on unrelated interfaces. While the fixup is removed, a better mechanism is still needed to dynamically determine the optimal combination of PHY and MAC delays to fully meet RGMII requirements without relying on Device Tree or global fixups. This would allow for robust operation across different hardware configurations. The Micrel driver is capable of using the interface mode value to calculate and apply better skew values, providing a configuration much closer to the RGMII specification than the fixup. Removing the fixup ensures better default behavior and prevents harm to other system interfaces.

2024-12-06net: usb: lan78xx: Remove LAN8835 PHY fixupOleksij Rempel
Remove the PHY fixup for the LAN8835 PHY in the lan78xx driver due to the following reasons: - There is no publicly available information about the LAN8835 PHY. However, it appears to be the integrated PHY used in the LAN7800 and LAN7850 USB Ethernet controllers. These PHYs use the GMII interface, not RGMII as configured by the fixup. - The correct driver for handling the LAN8835 PHY functionality is the Microchip PHY driver (`drivers/net/phy/microchip.c`), which properly supports these integrated PHYs. - The PHY ID `0x0007C130` is actually used by the LAN8742A PHY, which only supports RMII. This interface is incompatible with the LAN78xx MAC, as the LAN7801 (the only LAN78xx version without an integrated PHY) supports only RGMII. - The mask applied for this fixup is overly broad, inadvertently covering both Microchip LAN88xx PHYs and unrelated SMSC LAN8742A PHYs, leading to potential conflicts with other devices. - Testing has shown that removing this fixup for LAN7800 and LAN7850 does not result in any noticeable difference in functionality, as the Microchip PHY driver (`drivers/net/phy/microchip.c`) handles all necessary configurations for these integrated PHYs. - Registering this fixup globally (not limited to USB devices) risks conflicts by unintentionally modifying other interfaces whenever a LAN7801 adapter is connected to the system. Note that both LAN7800 and LAN7850 USB Ethernet controllers use an integrated PHY with the ID `0x0007C132`. Additionally, the LAN7515, a specialized part for Raspberry Pi, includes an integrated LAN7800 USB Ethernet controller and USB hub in a multifunctional chip design, and it also uses the same PHY ID (`0x0007C132`).

See a relevant issue fixed in : ac888d58869b ("net: do not delay dst_entries_add() in dst_release()") A fix is to queue the 'struct net' to be freed after one another cleanup_net() round (and existing rcu_barrier()) [1] BUG: KASAN: slab-use-after-free in dst_destroy (net/core/dst.c:112) Read of size 8 at addr ffff8882137ccab0 by task swapper/37/0 Dec 03 05:46:18 kernel: CPU: 37 UID: 0 PID: 0 Comm: swapper/37 Kdump: loaded Not tainted 6.12.0 #67 Hardware name: Red Hat KVM/RHEL, BIOS 1.16.1-1.el9 04/01/2014 Call Trace: <IRQ> dump_stack_lvl (lib/dump_stack.c:124) print_address_description.constprop.0 (mm/kasan/report.c:378) ?

2024-12-06net: tipc: remove one synchronize_net() from tipc_nametbl_stop()Eric Dumazet
tipc_exit_net() is very slow and is abused by syzbot. tipc_nametbl_stop() is called for each netns being dismantled. Calling synchronize_net() right before freeing tn->nametbl is a big hammer. Replace this with kfree_rcu(). Note that RCU is not properly used here, otherwise tn->nametbl should be cleared before the synchronize_net() or kfree_rcu(), or even before the cleanup loop. We might need to fix this at some point. Also note tipc uses other synchronize_rcu() calls, more work is needed to make tipc_exit_net() much faster.

2024-12-06bnxt_en: Fix potential crash when dumping FW log coredumpHongguang Gao
If the FW log context memory is retained after FW reset, the existing code is not handling the condition correctly and zeroes out the data structures. This potentially will cause a division by zero crash when the user runs ethtool -w. The last_type is also not set correctly when the context memory is retained. This will cause errors because the last_type signals to the FW that all context memory types have been configured.

The existing code is using RSS profile to determine IPV4/IPV6 GSO type on all chips older than 5760X. This won't work on 5750X chips that may be using modified RSS profiles. This commit from 2018 has updated the driver to not use RSS profile for HW GRO packets on newer chips: 50f011b63d8c ("bnxt_en: Update RSS setup and GRO-HW logic according to the latest spec.") However, a recent commit to add support for the newest 5760X chip broke the logic. If the GRO packet needs to be re-segmented by the stack, the wrong GSO type will cause the packet to be dropped. Fix it to only use RSS profile to determine GSO type on the oldest 5730X/5740X chips which cannot use the new method and is safe to use the RSS profiles. Also fix the L3/L4 hash type for RX packets by not using the RSS profile for the same reason. Use the ITYPE field in the RX completion to determine L3/L4 hash types correctly.

Petr Machata says: ==================== selftests: mlxsw: Add few fixes for sharedbuffer test Danielle Ratson writes: Currently, the sharedbuffer test fails sometimes because it is reading a maximum occupancy that is larger than expected on some different cases. This is happening because the test assumes that the packet it is sending is the only packet being passed to the device. In addition, some duplications on one hand, and redundant test cases on the other hand, were found in the test. Add egress filters on h1 and h2 that will guarantee that the packets in the buffer are sent in the test, and remove the redundant test cases. ==================== Link: https://patch.msgid.link/cover.1733414773.git.petrm@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2024-12-06selftests: mlxsw: sharedbuffer: Ensure no extra packets are countedDanielle Ratson
The test assumes that the packet it is sending is the only packet being passed to the device. However, it is not the case and so other packets are filling the buffers as well. Therefore, the test sometimes fails because it is reading a maximum occupancy that is larger than expected. Add egress filters on $h1 and $h2 that will guarantee the above.

2024-12-06selftests: mlxsw: sharedbuffer: Remove h1 ingress test caseDanielle Ratson
The test is sending only one packet generated with mausezahn from $h1 to $h2. However, for some reason, it is testing for non-zero maximum occupancy in both the ingress pool of $h1 and $h2. The former only passes when $h2 happens to send a packet. Avoid intermittent failures by removing unintentional test case regarding the ingress pool of $h1.
