793a539 cxl: Explicitly initialize resources when media is not ready When media is not ready do not assume that the capacity information from the identify command is valid, i.e. ->total_bytes ->partition_align_bytes ->{volatile,persistent}_only_bytes. Explicitly zero out the capacity resources and exit early. Given zero-init of those fields this patch is functionally equivalent to the prior state, but it improves readability and robustness going forward.

47ee3f1 x86: re-introduce support for ERMS copies for user space accesses I tried to streamline our user memory copy code fairly aggressively in commit adfcf4231b8c ("x86: don't use REP_GOOD or ERMS for user memory copies"), in order to then be able to clean up the code and inline the modern FSRM case in commit 577e6a7fd50d ("x86: inline the 'rep movs' in user copies for the FSRM case"). We had reports [1] of that causing regressions earlier with blogbench, but that turned out to be a horrible benchmark for that case, and not a sufficient reason for re-instating "rep movsb" on older machines. However, now Eric Dumazet reported [2] a regression in performance that seems to be a rather more real benchmark, where due to the removal of "rep movs" a TCP stream over a 100Gbps network no longer reaches line speed. And it turns out that with the simplified the calling convention for the non-FSRM case in commit 427fda2c8a49 ("x86: improve on the non-rep 'copy_user' function"), re-introducing the ERMS case is actually fairly simple. Of course, that "fairly simple" is glossing over several missteps due to having to fight our assembler alternative code. This code really wanted to rewrite a conditional branch to have two different targets, but that made objtool sufficiently unhappy that this instead just ended up doing a choice between "jump to the unrolled loop, or use 'rep movsb' directly". Let's see if somebody finds a case where the kernel memory copies also care (see commit 68674f94ffc9: "x86: don't use REP_GOOD or ERMS for small memory copies"). But Eric does argue that the user copies are special because networking tries to copy up to 32KB at a time, if order-3 pages allocations are possible. In-kernel memory copies are typically small, unless they are the special "copy pages at a time" kind that still use "rep movs".

9828ed3 module: error out early on concurrent load of the same module file It turns out that udev under certain circumstances will concurrently try to load the same modules over-and-over excessively. This isn't a kernel bug, but it ends up affecting the kernel, to the point that under certain circumstances we can fail to boot, because the kernel uses a lot of memory to read all the module data all at once. Note that it isn't a memory leak, it's just basically a thundering herd problem happening at bootup with a lot of CPUs, with the worst cases then being pretty bad. Admittedly the worst situations are somewhat contrived: lots and lots of CPUs, not a lot of memory, and KASAN enabled to make it all slower and as such (unintentionally) exacerbate the problem. Luis explains: [1] "My best assessment of the situation is that each CPU in udev ends up triggering a load of duplicate set of modules, not just one, but *a lot*. Not sure what heuristics udev uses to load a set of modules per CPU." Petr Pavlu chimes in: [2] "My understanding is that udev workers are forked. An initial kmod context is created by the main udevd process but no sharing happens after the fork. It means that the mentioned memory pool logic doesn't really kick in. Multiple parallel load requests come from multiple udev workers, for instance, each handling an udev event for one CPU device and making the exactly same requests as all others are doing at the same time. The optimization idea would be to recognize these duplicate requests at the udevd/kmod level and converge them" Note that module loading has tried to mitigate this issue before, see for example commit 064f4536d139 ("module: avoid allocation if module is already present and ready"), which has a few ASCII graphs on memory use due to this same issue. However, while that noticed that the module was already loaded, and exited with an error early before spending any more time on setting up the module, it didn't handle the case of multiple concurrent module loads all being active - but not complete - at the same time. Yes, one of them will eventually win the race and finalize its copy, and the others will then notice that the module already exists and error out, but while this all happens, we have tons of unnecessary concurrent work being done. Again, the real fix is for udev to not do that (maybe it should use threads instead of fork, and have actual shared data structures and not cause duplicate work). That real fix is apparently not trivial. But it turns out that the kernel already has a pretty good model for dealing with concurrent access to the same file: the i_writecount of the inode. In fact, the module loading already indirectly uses 'i_writecount' , because 'kernel_file_read()' will in fact do ret = deny_write_access(file); if (ret) return ret; ... allow_write_access(file); around the read of the file data. We do not allow concurrent writes to the file, and return -ETXTBUSY if the file was open for writing at the same time as the module data is loaded from it. And the solution to the reader concurrency problem is to simply extend this "no concurrent writers" logic to simply be "exclusive access". Note that "exclusive" in this context isn't really some absolute thing: it's only exclusion from writers and from other "special readers" that do this writer denial. So we simply introduce a variation of that "deny_write_access()" logic that not only denies write access, but also requires that this is the _only_ such access that denies write access. Which means that you can't start loading a module that is already being loaded as a module by somebody else, or you will get the same -ETXTBSY error that you would get if there were writers around. [ It also means that you can't try to load a currently executing executable as a module, for the same reason: executables do that same "deny_write_access()" thing, and that's obviously where the whole ETXTBSY logic traditionally came from. This is not a problem for kernel modules, since the set of normal executable files and kernel module files is entirely disjoint. ] This new function is called "exclusive_deny_write_access()", and the implementation is trivial, in that it's just an atomic decrement of i_writecount if it was 0 before. To use that new exclusivity check, all we then do is wrap the module loading with that exclusive_deny_write_access()() / allow_write_access() pair. The actual patch is a bit bigger than that, because we want to surround not just the "load file data" part, but the whole module setup, to get maximum exclusion. So this ends up splitting up "finit_module()" into a few helper functions to make it all very clear and legible. In Luis' test-case (bringing up 255 vcpu's in a virtual machine [3]), the "wasted vmalloc" space (ie module data read into a vmalloc'ed area in order to be loaded as a module, but then discarded because somebody else loaded the same module instead) dropped from 1.8GiB to 474kB. Yes, that's gigabytes to kilobytes. It doesn't drop completely to zero, because even with this change, you can still end up having completely serial pointless module loads, where one udev process has loaded a module fully (and thus the kernel has released that exclusive lock on the module file), and then another udev process tries to load the same module again. So while we cannot fully get rid of the fundamental bug in user space, we _can_ get rid of the excessive concurrent thundering herd effect. A couple of final side notes on this all: - This tweak only affects the "finit_module()" system call, which gives the kernel a file descriptor with the module data. You can also just feed the module data as raw data from user space with "init_module()" (note the lack of 'f' at the beginning), and obviously for that case we do _not_ have any "exclusive read" logic. So if you absolutely want to do things wrong in user space, and try to load the same module multiple times, and error out only later when the kernel ends up saying "you can't load the same module name twice", you can still do that. And in fact, some distros will do exactly that, because they will uncompress the kernel module data in user space before feeding it to the kernel (mainly because they haven't started using the new kernel side decompression yet). So this is not some absolute "you can't do concurrent loads of the same module". It's literally just a very simple heuristic that will catch it early in case you try to load the exact same module file at the same time, and in that case avoid a potentially nasty situation. - There is another user of "deny_write_access()": the verity code that enables fs-verity on a file (the FS_IOC_ENABLE_VERITY ioctl). If you use fs-verity and you care about verifying the kernel modules (which does make sense), you should do it *before* loading said kernel module. That may sound obvious, but now the implementation basically requires it. Because if you try to do it concurrently, the kernel may refuse to load the module file that is being set up by the fs-verity code. - This all will obviously mean that if you insist on loading the same module in parallel, only one module load will succeed, and the others will return with an error. That was true before too, but what is different is that the -ETXTBSY error can be returned *before* the success case of another process fully loading and instantiating the module. Again, that might sound obvious, and it is indeed the whole point of the whole change: we are much quicker to notice the whole "you're already in the process of loading this module". So it's very much intentional, but it does mean that if you just spray the kernel with "finit_module()", and expect that the module is immediately loaded afterwards without checking the return value, you are doing something horribly horribly wrong. I'd like to say that that would never happen, but the whole _reason_ for this commit is that udev is currently doing something horribly horribly wrong, so ...

9db8985 Merge tag 'vfs/v6.4-rc3/misc.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull vfs fixes from Christian Brauner: - During the acl rework we merged this cycle the generic_listxattr() helper had to be modified in a way that in principle it would allow for POSIX ACLs to be reported. At least that was the impression we had initially. Because before the acl rework POSIX ACLs would be reported if the filesystem did have POSIX ACL xattr handlers in sb->s_xattr. That logic changed and now we can simply check whether the superblock has SB_POSIXACL set and if the inode has inode->i_{default_}acl set report the appropriate POSIX ACL name. However, we didn't realize that generic_listxattr() was only ever used by two filesystems. Both of them don't support POSIX ACLs via sb->s_xattr handlers and so never reported POSIX ACLs via generic_listxattr() even if they raised SB_POSIXACL and did contain inodes which had acls set. The example here is nfs4. As a result, generic_listxattr() suddenly started reporting POSIX ACLs when it wouldn't have before. Since SB_POSIXACL implies that the umask isn't stripped in the VFS nfs4 can't just drop SB_POSIXACL from the superblock as it would also alter umask handling for them. So just have generic_listxattr() not report POSIX ACLs as it never did anyway. It's documented as such. - Our SB_* flags currently use a signed integer and we shift the last bit causing UBSAN to complain about undefined behavior. Switch to using unsigned. While the original patch used an explicit unsigned bitshift it's now pretty common to rely on the BIT() macro in a lot of headers nowadays. So the patch has been adjusted to use that. - Add Namjae as ntfs reviewer. They're already active this cycle so let's make it explicit right now. * tag 'vfs/v6.4-rc3/misc.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: ntfs: Add myself as a reviewer fs: don't call posix_acl_listxattr in generic_listxattr fs: fix undefined behavior in bit shift for SB_NOUSER 25 May 2023, 18:03:58 UTC

edc0a2b x86/topology: Fix erroneous smp_num_siblings on Intel Hybrid platforms Traditionally, all CPUs in a system have identical numbers of SMT siblings. That changes with hybrid processors where some logical CPUs have a sibling and others have none. Today, the CPU boot code sets the global variable smp_num_siblings when every CPU thread is brought up. The last thread to boot will overwrite it with the number of siblings of *that* thread. That last thread to boot will "win". If the thread is a Pcore, smp_num_siblings == 2. If it is an Ecore, smp_num_siblings == 1. smp_num_siblings describes if the *system* supports SMT. It should specify the maximum number of SMT threads among all cores. Ensure that smp_num_siblings represents the system-wide maximum number of siblings by always increasing its value. Never allow it to decrease. On MeteorLake-P platform, this fixes a problem that the Ecore CPUs are not updated in any cpu sibling map because the system is treated as an UP system when probing Ecore CPUs. Below shows part of the CPU topology information before and after the fix, for both Pcore and Ecore CPU (cpu0 is Pcore, cpu 12 is Ecore). ... -/sys/devices/system/cpu/cpu0/topology/package_cpus:000fff -/sys/devices/system/cpu/cpu0/topology/package_cpus_list:0-11 +/sys/devices/system/cpu/cpu0/topology/package_cpus:3fffff +/sys/devices/system/cpu/cpu0/topology/package_cpus_list:0-21 ... -/sys/devices/system/cpu/cpu12/topology/package_cpus:001000 -/sys/devices/system/cpu/cpu12/topology/package_cpus_list:12 +/sys/devices/system/cpu/cpu12/topology/package_cpus:3fffff +/sys/devices/system/cpu/cpu12/topology/package_cpus_list:0-21 Notice that the "before" 'package_cpus_list' has only one CPU.

533ab73 io_uring: unlock sqd->lock before sq thread release CPU The sq thread actively releases CPU resources by calling the cond_resched() and schedule() interfaces when it is idle. Therefore, more resources are available for other threads to run. There exists a problem in sq thread: it does not unlock sqd->lock before releasing CPU resources every time. This makes other threads pending on sqd->lock for a long time. For example, the following interfaces all require sqd->lock: io_sq_offload_create(), io_register_iowq_max_workers() and io_ring_exit_work(). Before the sq thread releases CPU resources, unlocking sqd->lock will provide the user a better experience because it can respond quickly to user requests.

ad42a35 udplite: Fix NULL pointer dereference in __sk_mem_raise_allocated(). syzbot reported [0] a null-ptr-deref in sk_get_rmem0() while using IPPROTO_UDPLITE (0x88): 14:25:52 executing program 1: r0 = socket$inet6(0xa, 0x80002, 0x88) We had a similar report [1] for probably sk_memory_allocated_add() in __sk_mem_raise_allocated(), and commit c915fe13cbaa ("udplite: fix NULL pointer dereference") fixed it by setting .memory_allocated for udplite_prot and udplitev6_prot. To fix the variant, we need to set either .sysctl_wmem_offset or .sysctl_rmem. Now UDP and UDPLITE share the same value for .memory_allocated, so we use the same .sysctl_wmem_offset for UDP and UDPLITE.

aa015a2 Merge branch 'net-phy-mscc-support-vsc8501' David Epping says: ==================== net: phy: mscc: support VSC8501 this updated series of patches adds support for the VSC8501 Ethernet PHY and fixes support for the VSC8502 PHY in cases where no other software (like U-Boot) has initialized the PHY after power up. The first patch simply adds the VSC8502 to the MODULE_DEVICE_TABLE, where I guess it was unintentionally missing. I have no hardware to test my change. The second patch adds the VSC8501 PHY with exactly the same driver implementation as the existing VSC8502. The (new) third patch removes phydev locking from vsc85xx_rgmii_set_skews(), as discussed for v2 of the patch set. The (now) fourth patch fixes the initialization for VSC8501 and VSC8502. I have tested this patch with VSC8501 on hardware in RGMII mode only. https://ww1.microchip.com/downloads/aemDocuments/documents/UNG/ProductDocuments/DataSheets/VSC8501-03_Datasheet_60001741A.PDF https://ww1.microchip.com/downloads/aemDocuments/documents/UNG/ProductDocuments/DataSheets/VSC8502-03_Datasheet_60001742B.pdf Table 4-42 "RGMII CONTROL, ADDRESS 20E2 (0X14)" Bit 11 for each of them. By default the RX_CLK is disabled for these PHYs. In cases where no other software, like U-Boot, enabled the clock, this results in no received packets being handed to the MAC. The patch enables this clock output. According to Microchip support (case number 01268776) this applies to all modes (RGMII, GMII, and MII). Other PHYs sharing the same register map and code, like VSC8530/31/40/41 have the clock enabled and the relevant bit 11 is reserved and read-only for them. As per previous discussion the patch still clears the bit on these PHYs, too, possibly more easily supporting other future PHYs implementing this functionality. For the VSC8572 family of PHYs, having a different register map, no such changes are applied. ==================== Link: https://lore.kernel.org/r/20230523153108.18548-1-david.epping@missinglinkelectronics.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> 25 May 2023, 05:14:29 UTC

cb8b02f cifs: mapchars mount option ignored There are two ways that special characters (not allowed in some other operating systems like Windows, but allowed in POSIX) have been mapped in the past ("SFU" and "SFM" mappings) to allow them to be stored in a range reserved for special chars. The default for Linux has been to use "mapposix" (ie the SFM mapping) but the conversion to the new mount API in the 5.11 kernel broke the ability to override the default mapping of the reserved characters (like '?' and '*' and '\') via "mapchars" mount option. This patch fixes that - so can now mount with "mapchars" mount option to override the default ("mapposix" ie SFM) mapping.

335b422 x86/pci/xen: populate MSI sysfs entries Commit bf5e758f02fc ("genirq/msi: Simplify sysfs handling") reworked the creation of sysfs entries for MSI IRQs. The creation used to be in msi_domain_alloc_irqs_descs_locked after calling ops->domain_alloc_irqs. Then it moved into __msi_domain_alloc_irqs which is an implementation of domain_alloc_irqs. However, Xen comes with the only other implementation of domain_alloc_irqs and hence doesn't run the sysfs population code anymore. Commit 6c796996ee70 ("x86/pci/xen: Fixup fallout from the PCI/MSI overhaul") set the flag MSI_FLAG_DEV_SYSFS for the xen msi_domain_info but that doesn't actually have an effect because Xen uses it's own domain_alloc_irqs implementation.

04910d8 net: ethernet: mtk_eth_soc: fix QoS on DSA MAC on non MTK_NETSYS_V2 SoCs The commit c6d96df9fa2c ("net: ethernet: mtk_eth_soc: drop generic vlan rx offload, only use DSA untagging") makes VLAN RX offloading to be only used on the SoCs without the MTK_NETSYS_V2 ability (which are not just MT7621 and MT7622). The commit disables the proper handling of special tagged (DSA) frames, added with commit 87e3df4961f4 ("net-next: ethernet: mediatek: add CDM able to recognize the tag for DSA"), for non MTK_NETSYS_V2 SoCs when it finds a MAC that does not use DSA. So if the other MAC uses DSA, the CDMQ component transmits DSA tagged frames to the CPU improperly. This issue can be observed on frames with TCP, for example, a TCP speed test using iperf3 won't work. The commit disables the proper handling of special tagged (DSA) frames because it assumes that these SoCs don't use more than one MAC, which is wrong. Although I made Frank address this false assumption on the patch log when they sent the patch on behalf of Felix, the code still made changes with this assumption. Therefore, the proper handling of special tagged (DSA) frames must be kept enabled in all circumstances as it doesn't affect non DSA tagged frames. Hardware DSA untagging, introduced with the commit 2d7605a72906 ("net: ethernet: mtk_eth_soc: enable hardware DSA untagging"), and VLAN RX offloading are operations on the two CDM components of the frame engine, CDMP and CDMQ, which connect to Packet DMA (PDMA) and QoS DMA (QDMA) and are between the MACs and the CPU. These operations apply to all MACs of the SoC so if one MAC uses DSA and the other doesn't, the hardware DSA untagging operation will cause the CDMP component to transmit non DSA tagged frames to the CPU improperly. Since the VLAN RX offloading feature configuration was dropped, VLAN RX offloading can only be used along with hardware DSA untagging. So, for the case above, we need to disable both features and leave it to the CPU, therefore software, to untag the DSA and VLAN tags. So the correct way to handle this is: For all SoCs: Enable the proper handling of special tagged (DSA) frames (MTK_CDMQ_IG_CTRL). For non MTK_NETSYS_V2 SoCs: Enable hardware DSA untagging (MTK_CDMP_IG_CTRL). Enable VLAN RX offloading (MTK_CDMP_EG_CTRL). When a non MTK_NETSYS_V2 SoC MAC does not use DSA: Disable hardware DSA untagging (MTK_CDMP_IG_CTRL). Disable VLAN RX offloading (MTK_CDMP_EG_CTRL).

d6c36cb r8169: Use a raw_spinlock_t for the register locks. The driver's interrupt service routine is requested with the IRQF_NO_THREAD if MSI is available. This means that the routine is invoked in hardirq context even on PREEMPT_RT. The routine itself is relatively short and schedules a worker, performs register access and schedules NAPI. On PREEMPT_RT, scheduling NAPI from hardirq results in waking ksoftirqd for further processing so using NAPI threads with this driver is highly recommended since it NULL routes the threaded-IRQ efforts. Adding rtl_hw_aspm_clkreq_enable() to the ISR is problematic on PREEMPT_RT because the function uses spinlock_t locks which become sleeping locks on PREEMPT_RT. The locks are only used to protect register access and don't nest into other functions or locks. They are also not used for unbounded period of time. Therefore it looks okay to convert them to raw_spinlock_t. Convert the three locks which are used from the interrupt service routine to raw_spinlock_t.

368d3cb page_pool: fix inconsistency for page_pool_ring_[un]lock() page_pool_ring_[un]lock() use in_softirq() to decide which spin lock variant to use, and when they are called in the context with in_softirq() being false, spin_lock_bh() is called in page_pool_ring_lock() while spin_unlock() is called in page_pool_ring_unlock(), because spin_lock_bh() has disabled the softirq in page_pool_ring_lock(), which causes inconsistency for spin lock pair calling. This patch fixes it by returning in_softirq state from page_pool_producer_lock(), and use it to decide which spin lock variant to use in page_pool_producer_unlock(). As pool->ring has both producer and consumer lock, so rename it to page_pool_producer_[un]lock() to reflect the actual usage. Also move them to page_pool.c as they are only used there, and remove the 'inline' as the compiler may have better idea to do inlining or not.
