2024-05-31null_blk: Do not allow runt zone with zone capacity smaller then zone sizeDamien Le Moal1-0/+11
A zoned device with a smaller last zone together with a zone capacity smaller than the zone size does make any sense as that does not correspond to any possible setup for a real device: 1) For ZNS and zoned UFS devices, all zones are always the same size. 2) For SMR HDDs, all zones always have the same capacity. In other words, if we have a smaller last runt zone, then this zone capacity should always be equal to the zone size. Add a check in null_init_zoned_dev() to prevent a configuration to have both a smaller zone size and a zone capacity smaller than the zone size.

2024-05-30riscv: prevent pt_regs corruption for secondary idle threadsSergey Matyukevich2-3/+2
Top of the kernel thread stack should be reserved for pt_regs. However this is not the case for the idle threads of the secondary boot harts. Their stacks overlap with their pt_regs, so both may get corrupted. Similar issue has been fixed for the primary hart, see c7cdd96eca28 ("riscv: prevent stack corruption by reserving task_pt_regs(p) early"). However that fix was not propagated to the secondary harts. The problem has been noticed in some CPU hotplug tests with V enabled. The function smp_callin stored several registers on stack, corrupting top of pt_regs structure including status field. As a result, kernel attempted to save or restore inexistent V context.

2024-05-30x86/cpu: Provide default cache line size if not enumeratedDave Hansen1-0/+4
tl;dr: CPUs with CPUID.80000008H but without CPUID.01H:EDX[CLFSH] will end up reporting cache_line_size()==0 and bad things happen. Fill in a default on those to avoid the problem. Long Story: The kernel dies a horrible death if c->x86_cache_alignment (aka. cache_line_size() is 0. Normally, this value is populated from c->x86_clflush_size. Right now the code is set up to get c->x86_clflush_size from two places. First, modern CPUs get it from CPUID. Old CPUs that don't have leaf 0x80000008 (or CPUID at all) just get some sane defaults from the kernel in get_cpu_address_sizes(). The vast majority of CPUs that have leaf 0x80000008 also get ->x86_clflush_size from CPUID. But there are oddballs. Intel Quark CPUs[1] and others[2] have leaf 0x80000008 but don't set CPUID.01H:EDX[CLFSH], so they skip over filling in ->x86_clflush_size: cpuid(0x00000001, &tfms, &misc, &junk, &cap0); if (cap0 & (1<<19)) c->x86_clflush_size = ((misc >> 8) & 0xff) * 8; So they: land in get_cpu_address_sizes() and see that CPUID has level 0x80000008 and jump into the side of the if() that does not fill in c->x86_clflush_size. That assigns a 0 to c->x86_cache_alignment, and hilarity ensues in code like: buffer = kzalloc(ALIGN(sizeof(*buffer), cache_line_size()), GFP_KERNEL); To fix this, always provide a sane value for ->x86_clflush_size. Big thanks to Andy Shevchenko for finding and reporting this and also providing a first pass at a fix. But his fix was only partial and only worked on the Quark CPUs. It would not, for instance, have worked on the QEMU config. 1. https://raw.githubusercontent.com/InstLatx64/InstLatx64/master/GenuineIntel/GenuineIntel0000590_Clanton_03_CPUID.txt 2. You can also get this behavior if you use "-cpu 486,+clzero" in QEMU.

2024-05-30io_uring/rw: Free iovec before cleaning async dataBreno Leitao1-0/+5
kmemleak shows that there is a memory leak in io_uring read operation, where a buffer is allocated at iovec import, but never de-allocated. The memory is allocated at io_async_rw->free_iovec, but, then io_async_rw is kfreed, taking the allocated memory with it. I saw this happening when the read operation fails with -11 (EAGAIN). This is the kmemleak splat. unreferenced object 0xffff8881da591c00 (size 256): ... backtrace (crc 7a15bdee): [<00000000256f2de4>] __kmalloc+0x2d6/0x410 [<000000007a9f5fc7>] iovec_from_user.part.0+0xc6/0x160 [<00000000cecdf83a>] __import_iovec+0x50/0x220 [<00000000d1d586a2>] __io_import_iovec+0x13d/0x220 [<0000000054ee9bd2>] io_prep_rw+0x186/0x340 [<00000000a9c0372d>] io_prep_rwv+0x31/0x120 [<000000001d1170b9>] io_prep_readv+0xe/0x30 [<0000000070b8eb67>] io_submit_sqes+0x1bd/0x780 [<00000000812496d4>] __do_sys_io_uring_enter+0x3ed/0x5b0 [<0000000081499602>] do_syscall_64+0x5d/0x170 [<00000000de1c5a4d>] entry_SYSCALL_64_after_hwframe+0x76/0x7e This occurs because the async data cleanup functions are not set for read/write operations. As a result, the potentially allocated iovec in the rw async data is not freed before the async data is released, leading to a memory leak. With this following patch, kmemleak does not show the leaked memory anymore, and all liburing tests pass.

2024-05-30ASoC: SOF: ipc4-topology: Fix nhlt configuration blobMark Brown3-58/+115
Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>: The existing logic to pick a DMIC blob is based on several historical assumptions that the NHLT in BIOS always contains 32-bits per sample type (first patch, [1]). The other issue with the existing logic is that it was designed to care only about the bit depth of the format and fails to find the existing and correct blob when rate/channels are different on the FE side compared to what we should be using on the DAI side (we have components in path which can change rate/channel count). These issues have not been observed in past but with new MTL based (Windows) laptops and new topologies to enhance the audio quality, we started to see weird issues around how our assumptions of vendors failed. Since some NHLT blob handling cleanup has been done for 6.10, this series will complete that work to cover even cases that we don't anticipate to see.

2024-05-30powerpc/uaccess: Use YZ asm constraint for ldMichael Ellerman1-0/+11
The 'ld' instruction requires a 4-byte aligned displacement because it is a DS-form instruction. But the "m" asm constraint doesn't enforce that. Add a special case of __get_user_asm2_goto() so that the "YZ" constraint can be used for "ld". The "Z" constraint is documented in the GCC manual PowerPC machine constraints, and specifies a "memory operand accessed with indexed or indirect addressing". "Y" is not documented in the manual but specifies a "memory operand for a DS-form instruction". Using both allows the compiler to generate a DS-form "ld" or X-form "ldx" as appropriate. The change has to be conditional on CONFIG_PPC_KERNEL_PREFIXED because the "Y" constraint does not guarantee 4-byte alignment when prefixed instructions are enabled. No build errors have been reported due to this, but the possibility is there depending on compiler code generation decisions.

2024-05-30powerpc/uaccess: Fix build errors seen with GCC 13/14Michael Ellerman1-0/+16
Building ppc64le_defconfig with GCC 14 fails with assembler errors: CC fs/readdir.o /tmp/ccdQn0mD.s: Assembler messages: /tmp/ccdQn0mD.s:212: Error: operand out of domain (18 is not a multiple of 4) /tmp/ccdQn0mD.s:226: Error: operand out of domain (18 is not a multiple of 4) ...

A similar error is seen with GCC 13 and CONFIG_UBSAN_SIGNED_WRAP=y. The fix is to change the constraint on the memory operand to put_user(), from "m" which is a general memory reference to "YZ". The "Z" constraint is documented in the GCC manual PowerPC machine constraints, and specifies a "memory operand accessed with indexed or indirect addressing". "Y" is not documented in the manual but specifies a "memory operand for a DS-form instruction". Using both allows the compiler to generate a DS-form "std" or X-form "stdx" as appropriate. The change has to be conditional on CONFIG_PPC_KERNEL_PREFIXED because the "Y" constraint does not guarantee 4-byte alignment when prefixed instructions are enabled. Unfortunately clang doesn't support the "Y" constraint so that has to be behind an ifdef. Although the build error is only seen with GCC 13/14, that appears to just be luck. The constraint has been incorrect since it was first added.

2024-05-30ASoC: SOF: ipc4-topology: Adjust the params based on DAI formatsPeter Ujfalusi1-14/+57
Currently we only check the bit depth value among to DAI formats, but other parameters might be constant, like number of channels and/or rate. In capture we use the fe params as a reference to find the format and blob which should be used, but in the path we can have components which can handle expanding/narrowing number of channels or do a resample. In these cases the topology is expected to have 'fixed' parameter for channels/rates/bit depth and the conversion to the fe format is going to be done within the path. In practice this patch fixes issues like: All DMIC formats are fixed four channels We have a component which converts the four channel to stereo FE is opened with 2 channel Even if we have the correct bit depth format and blob (for four channel) we will still be looking for stereo configurations, which will fail. Note: the adjustment of params have switched order with the checking of single bit depth (needed for the NHLT blob fallback support). This change is non function, just that if the sof_ipc4_narrow_params_to_format() would fail, there is no point of checking the single bit depth.

2024-05-30ice: check for unregistering correct number of devlink paramsDave Ertman1-9/+22
On module load, the ice driver checks for the lack of a specific PF capability to determine if it should reduce the number of devlink params to register. One situation when this test returns true is when the driver loads in safe mode. The same check is not present on the unload path when devlink params are unregistered. This results in the driver triggering a WARN_ON in the kernel devlink code. The current check and code path uses a reduction in the number of elements reported in the list of params. This is fragile and not good for future maintaining. Change the parameters to be held in two lists, one always registered and one dependent on the check. Add a symmetrical check in the unload path so that the correct parameters are unregistered as well.

Two new functions, i40e_io_suspend() and i40e_io_resume(), have been introduced. These functions were factored out from the existing i40e_suspend() and i40e_resume() respectively.

2024-05-30e1000e: move force SMBUS near the end of enable_ulp functionHui Wang2-18/+22
The commit 861e8086029e ("e1000e: move force SMBUS from enable ulp function to avoid PHY loss issue") introduces a regression on PCH_MTP_I219_LM18 (PCIID: 0x8086550A). Without the referred commit, the ethernet works well after suspend and resume, but after applying the commit, the ethernet couldn't work anymore after the resume and the dmesg shows that the NIC link changes to 10Mbps (1000Mbps originally): [ 43.305084] e1000e 0000:00:1f.6 enp0s31f6: NIC Link is Up 10 Mbps Full Duplex, Flow Control: Rx/Tx Without the commit, the force SMBUS code will not be executed if "return 0" or "goto out" is executed in the enable_ulp(), and in my case, the "goto out" is executed since FWSM_FW_VALID is set. But after applying the commit, the force SMBUS code will be ran unconditionally. Here move the force SMBUS code back to enable_ulp() and put it immediately ahead of hw->phy.ops.release(hw), this could allow the longest settling time as possible for interface in this function and doesn't change the original code logic. The issue was found on a Lenovo laptop with the ethernet hw as below: 00:1f.6 Ethernet controller [0200]: Intel Corporation Device [8086:550a] (rev 20). And this patch is verified (cable plug and unplug, system suspend and resume) on Lenovo laptops with ethernet hw: [8086:550a], [8086:550b], [8086:15bb], [8086:15be], [8086:1a1f], [8086:1a1c] and [8086:0dc7].

2024-05-30net: fix __dst_negative_advice() raceEric Dumazet5-47/+30
__dst_negative_advice() does not enforce proper RCU rules when sk->dst_cache must be cleared, leading to possible UAF. RCU rules are that we must first clear sk->sk_dst_cache, then call dst_release(old_dst). Note that sk_dst_reset(sk) is implementing this protocol correctly, while __dst_negative_advice() uses the wrong order. Given that ip6_negative_advice() has special logic against RTF_CACHE, this means each of the three ->negative_advice() existing methods must perform the sk_dst_reset() themselves. Note the check against NULL dst is centralized in __dst_negative_advice(), there is no need to duplicate it in various callbacks. Many thanks to Clement Lecigne for tracking this issue. This old bug became visible after the blamed commit, using UDP sockets.

A new error path was added to the fwnode_for_each_available_node() loop in ltc2992_parse_dt(), which leads to an early return that requires a call to fwnode_handle_put() to avoid a memory leak in that case. Add the missing fwnode_handle_put() in the error path from a zero value shunt resistor.
