[PATCH v7 02/12] i2c: rtl9300: ensure data length is within supported range

by Jonas Jelonek

Add an explicit check for the xfer length to 'rtl9300_i2c_config_xfer' to ensure the data length isn't within the supported range. In particular a data length of 0 is not supported by the hardware and causes unintended or destructive behaviour. This limitation becomes obvious when looking at the register documentation [1]. 4 bits are reserved for DATA_WIDTH and the value of these 4 bits is used as N + 1, allowing a data length range of 1 <= len <= 16. Affected by this is the SMBus Quick Operation which works with a data length of 0. Passing 0 as the length causes an underflow of the value due to: (len - 1) & 0xf and effectively specifying a transfer length of 16 via the registers. This causes a 16-byte write operation instead of a Quick Write. For example, on SFP modules without write-protected EEPROM this soft-bricks them by overwriting some initial bytes. For completeness, also add a quirk for the zero length.

[PATCH v7 01/12] i2c: rtl9300: fix channel number bound check

by Jonas Jelonek

Fix the current check for number of channels (child nodes in the device tree). Before, this was: if (device_get_child_node_count(dev) >= RTL9300_I2C_MUX_NCHAN) RTL9300_I2C_MUX_NCHAN gives the maximum number of channels so checking with '>=' isn't correct because it doesn't allow the last channel number. Thus, fix it to: if (device_get_child_node_count(dev) > RTL9300_I2C_MUX_NCHAN) Issue occured on a TP-Link TL-ST1008F v2.0 device (8 SFP+ ports) and fix is tested there.

[PATCH v2] scsi: lpfc: Fix buffer free/clear order in deferred receive path

by John Evans

Fix a use-after-free window by correcting the buffer release sequence in the deferred receive path. The code freed the RQ buffer first and only then cleared the context pointer under the lock. Concurrent paths (e.g., ABTS and the repost path) also inspect and release the same pointer under the lock, so the old order could lead to double-free/UAF. Note that the repost path already uses the correct pattern: detach the pointer under the lock, then free it after dropping the lock. The deferred path should do the same.

[regression] Wireguard fragmentation fails with VXLAN since 8930424777e4 ("tunnels: Accept PACKET_HOST skb_tunnel_check_pmtu().") causing network timeouts

by Salvatore Bonaccorso

Hi, Charles Bordet reported the following issue (full context in https://bugs.debian.org/1108860) > Dear Maintainer, > > What led up to the situation? > We run a production environment using Debian 12 VMs, with a network > topology involving VXLAN tunnels encapsulated inside Wireguard > interfaces. This setup has worked reliably for over a year, with MTU set > to 1500 on all interfaces except the Wireguard interface (set to 1420). > Wireguard kernel fragmentation allowed this configuration to function > without issues, even though the effective path MTU is lower than 1500. > > What exactly did you do (or not do) that was effective (or ineffective)? > We performed a routine system upgrade, updating all packages include the > kernel. After the upgrade, we observed severe network issues (timeouts, > very slow HTTP/HTTPS, and apt update failures) on all VMs behind the > router. SSH and small-packet traffic continued to work. > > To diagnose, we: > > * Restored a backup (with the previous kernel): the problem disappeared. > * Repeated the upgrade, confirming the issue reappeared. > * Systematically tested each kernel version from 6.1.124-1 up to > 6.1.140-1. The problem first appears with kernel 6.1.135-1; all earlier > versions work as expected. > * Kernel version from the backports (6.12.32-1) did not resolve the > problem. > > What was the outcome of this action? > > * With kernel 6.1.135-1 or later, network timeouts occur for > large-packet protocols (HTTP, apt, etc.), while SSH and small-packet > protocols work. > * With kernel 6.1.133-1 or earlier, everything works as expected. > > What outcome did you expect instead? > We expected the network to function as before, with Wireguard handling > fragmentation transparently and no application-level timeouts, > regardless of the kernel version. While triaging the issue we found that the commit 8930424777e4 ("tunnels: Accept PACKET_HOST in skb_tunnel_check_pmtu()." introduces the issue and Charles confirmed that the issue was present as well in 6.12.35 and 6.15.4 (other version up could potentially still be affected, but we wanted to check it is not a 6.1.y specific regression). Reverthing the commit fixes Charles' issue. Does that ring a bell? Regards, Salvatore

[PATCH] net: dsa: mv88e6xxx: Fix fwnode reference leaks in mv88e6xxx_port_setup_leds

by Miaoqian Lin

Fix multiple fwnode reference leaks: 1. The function calls fwnode_get_named_child_node() to get the "leds" node, but never calls fwnode_handle_put(leds) to release this reference. 2. Within the fwnode_for_each_child_node() loop, the early return paths that don't properly release the "led" fwnode reference. This fix follows the same pattern as commit d029edefed39 ("net dsa: qca8k: fix usages of device_get_named_child_node()") Fixes: 94a2a84f5e9e ("net: dsa: mv88e6xxx: Support LED control") Cc: stable(a)vger.kernel.org Signed-off-by: Miaoqian Lin <linmq006(a)gmail.com> --- drivers/net/dsa/mv88e6xxx/leds.c | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/drivers/net/dsa/mv88e6xxx/leds.c b/drivers/net/dsa/mv88e6xxx/leds.c index 1c88bfaea46b..dcc765066f9c 100644 --- a/drivers/net/dsa/mv88e6xxx/leds.c +++ b/drivers/net/dsa/mv88e6xxx/leds.c @@ -779,6 +779,8 @@ int mv88e6xxx_port_setup_leds(struct mv88e6xxx_chip *chip, int port) continue; if (led_num > 1) { dev_err(dev, "invalid LED specified port %d\n", port); + fwnode_handle_put(led); + fwnode_handle_put(leds); return -EINVAL; } @@ -823,17 +825,23 @@ int mv88e6xxx_port_setup_leds(struct mv88e6xxx_chip *chip, int port) init_data.devname_mandatory = true; init_data.devicename = kasprintf(GFP_KERNEL, "%s:0%d:0%d", chip->info->name, port, led_num); - if (!init_data.devicename) + if (!init_data.devicename) { + fwnode_handle_put(led); + fwnode_handle_put(leds); return -ENOMEM; + } ret = devm_led_classdev_register_ext(dev, l, &init_data); kfree(init_data.devicename); if (ret) { dev_err(dev, "Failed to init LED %d for port %d", led_num, port); + fwnode_handle_put(led); + fwnode_handle_put(leds); return ret; } } + fwnode_handle_put(leds); return 0; } -- 2.35.1

[PATCH 1/2] ALSA: hda: tas2781: fix tas2563 EFI data endianness

Before conversion to unify the calibration data management, the tas2563_apply_calib() function performed the big endian conversion and wrote the calibration data to the device.

[RFC 1/8] powerpc/mm: Fix SLB multihit issue during SLB preload

by Ritesh Harjani (IBM)

From: Donet Tom <donettom(a)linux.ibm.com> On systems using the hash MMU, there is a software SLB preload cache that mirrors the entries loaded into the hardware SLB buffer. This preload cache is subject to periodic eviction — typically after every 256 context switches — to remove old entry. To optimize performance, the kernel skips switch_mmu_context() in switch_mm_irqs_off() when the prev and next mm_struct are the same. However, on hash MMU systems, this can lead to inconsistencies between the hardware SLB and the software preload cache. If an SLB entry for a process is evicted from the software cache on one CPU, and the same process later runs on another CPU without executing switch_mmu_context(), the hardware SLB may retain stale entries. If the kernel then attempts to reload that entry, it can trigger an SLB multi-hit error. The following timeline shows how stale SLB entries are created and can cause a multi-hit error when a process moves between CPUs without a MMU context switch. CPU 0 CPU 1 ----- ----- Process P exec swapper/1 load_elf_binary begin_new_exc activate_mm switch_mm_irqs_off switch_mmu_context switch_slb /* * This invalidates all * the entries in the HW * and setup the new HW * SLB entries as per the * preload cache. */ context_switch sched_migrate_task migrates process P to cpu-1 Process swapper/0 context switch (to process P) (uses mm_struct of Process P) switch_mm_irqs_off() switch_slb load_slb++ /* * load_slb becomes 0 here * and we evict an entry from * the preload cache with * preload_age(). We still * keep HW SLB and preload * cache in sync, that is * because all HW SLB entries * anyways gets evicted in * switch_slb during SLBIA. * We then only add those * entries back in HW SLB, * which are currently * present in preload_cache * (after eviction). */ load_elf_binary continues... setup_new_exec() slb_setup_new_exec() sched_switch event sched_migrate_task migrates process P to cpu-0 context_switch from swapper/0 to Process P switch_mm_irqs_off() /* * Since both prev and next mm struct are same we don't call * switch_mmu_context(). This will cause the HW SLB and SW preload * cache to go out of sync in preload_new_slb_context. Because there * was an SLB entry which was evicted from both HW and preload cache * on cpu-1. Now later in preload_new_slb_context(), when we will try * to add the same preload entry again, we will add this to the SW * preload cache and then will add it to the HW SLB. Since on cpu-0 * this entry was never invalidated, hence adding this entry to the HW * SLB will cause a SLB multi-hit error. */ load_elf_binary continues... START_THREAD start_thread preload_new_slb_context /* * This tries to add a new EA to preload cache which was earlier * evicted from both cpu-1 HW SLB and preload cache. This caused the * HW SLB of cpu-0 to go out of sync with the SW preload cache. The * reason for this was, that when we context switched back on CPU-0, * we should have ideally called switch_mmu_context() which will * bring the HW SLB entries on CPU-0 in sync with SW preload cache * entries by setting up the mmu context properly. But we didn't do * that since the prev mm_struct running on cpu-0 was same as the * next mm_struct (which is true for swapper / kernel threads). So * now when we try to add this new entry into the HW SLB of cpu-0, * we hit a SLB multi-hit error. */ WARNING: CPU: 0 PID: 1810970 at arch/powerpc/mm/book3s64/slb.c:62 assert_slb_presence+0x2c/0x50(48 results) 02:47:29 [20157/42149] Modules linked in: CPU: 0 UID: 0 PID: 1810970 Comm: dd Not tainted 6.16.0-rc3-dirty #12 VOLUNTARY Hardware name: IBM pSeries (emulated by qemu) POWER8 (architected) 0x4d0200 0xf000004 of:SLOF,HEAD hv:linux,kvm pSeries NIP: c00000000015426c LR: c0000000001543b4 CTR: 0000000000000000 REGS: c0000000497c77e0 TRAP: 0700 Not tainted (6.16.0-rc3-dirty) MSR: 8000000002823033 <SF,VEC,VSX,FP,ME,IR,DR,RI,LE> CR: 28888482 XER: 00000000 CFAR: c0000000001543b0 IRQMASK: 3 <...> NIP [c00000000015426c] assert_slb_presence+0x2c/0x50 LR [c0000000001543b4] slb_insert_entry+0x124/0x390 Call Trace: 0x7fffceb5ffff (unreliable) preload_new_slb_context+0x100/0x1a0 start_thread+0x26c/0x420 load_elf_binary+0x1b04/0x1c40 bprm_execve+0x358/0x680 do_execveat_common+0x1f8/0x240 sys_execve+0x58/0x70 system_call_exception+0x114/0x300 system_call_common+0x160/0x2c4 >From the above analysis, during early exec the hardware SLB is cleared, and entries from the software preload cache are reloaded into hardware by switch_slb. However, preload_new_slb_context and slb_setup_new_exec also attempt to load some of the same entries, which can trigger a multi-hit. In most cases, these additional preloads simply hit existing entries and add nothing new. Removing these functions avoids redundant preloads and eliminates the multi-hit issue. This patch removes these two functions. We tested process switching performance using the context_switch benchmark on POWER9/hash, and observed no regression. Without this patch: 129041 ops/sec With this patch: 129341 ops/sec We also measured SLB faults during boot, and the counts are essentially the same with and without this patch.
