      cxl: Explicitly initialize resources when media is not ready · 793a539a
      Dave Jiang authored
      
      
      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.

      x86: re-introduce support for ERMS copies for user space accesses · 47ee3f1d
      Linus Torvalds authored
      I tried to streamline our user memory copy code fairly aggressively in
      commit adfcf423 ("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 577e6a7f ("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 427fda2c ("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 68674f94: "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".

      module: error out early on concurrent load of the same module file · 9828ed3f
      Linus Torvalds authored
      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 064f4536 ("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

       - 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.

      x86/topology: Fix erroneous smp_num_siblings on Intel Hybrid platforms · edc0a2b5
      Zhang Rui authored
      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.  This
      means that userspace tools like lscpu will see a little laptop like
      an 11-socket system:
      
      -Core(s) per socket:  1
      -Socket(s):           11
      +Core(s) per socket:  16
      +Socket(s):           1
      
      This is also expected to make the scheduler do rather wonky things
      too.

      cpufreq: amd-pstate: Update policy->cur in amd_pstate_adjust_perf() · 3bf8c630
      Wyes Karny authored
      Driver should update policy->cur after updating the frequency.
      Currently amd_pstate doesn't update policy->cur when `adjust_perf`
      is used. Which causes /proc/cpuinfo to show wrong cpu frequency.
      Fix this by updating policy->cur with correct frequency value in
      adjust_perf function callback.
      
      - Before the fix: (setting min freq to 1.5 MHz)
      
      [root@amd]# cat /proc/cpuinfo | grep "cpu MHz" | sort | uniq --count
            1 cpu MHz         : 1777.016
            1 cpu MHz         : 1797.160
            1 cpu MHz         : 1797.270
          189 cpu MHz         : 400.000
      
      - After the fix: (setting min freq to 1.5 MHz)
      
      [root@amd]# cat /proc/cpuinfo | grep "cpu MHz" | sort | uniq --count
            1 cpu MHz         : 1753.353

            1 cpu MHz         : 1779.900
