           completely. With 'nosmt' being a popular option it's required to

      leds: trigger: netdev: use memcpy in device_name_store · 90934643
      Rasmus Villemoes authored
      If userspace doesn't end the input with a newline (which can easily
      happen if the write happens from a C program that does write(fd,
      iface, strlen(iface))), we may end up including garbage from a
      previous, longer value in the device_name. For example
      
      # cat device_name
      
      # printf 'eth12' > device_name
      # cat device_name
      eth12
      # printf 'eth3' > device_name
      # cat device_name
      eth32
      
      I highly doubt anybody is relying on this behaviour, so switch to
      simply copying the bytes (we've already checked that size is <
      IFNAMSIZ) and unconditionally zero-terminate it; of course, we also
      still have to strip a trailing newline.
      
      This is also preparation for future patches.

         allocations, so that dma-handles could be allocated in an exclusion
         range, leading to data corruption. Exclusion ranges have not been
         used by any firmware up to now, so this issue remained undiscovered
         for quite some time.

         tries to allocate the default domain for an iommu group and the

      LSM: Revive CONFIG_DEFAULT_SECURITY_* for "make oldconfig" · 2623c4fb
      Kees Cook authored
      Commit 70b62c25 ("LoadPin: Initialize as ordered LSM") removed
      CONFIG_DEFAULT_SECURITY_{SELINUX,SMACK,TOMOYO,APPARMOR,DAC} from
      security/Kconfig and changed CONFIG_LSM to provide a fixed ordering as a
      default value. That commit expected that existing users (upgrading from
      Linux 5.0 and earlier) will edit CONFIG_LSM value in accordance with
      their CONFIG_DEFAULT_SECURITY_* choice in their old kernel configs. But
      since users might forget to edit CONFIG_LSM value, this patch revives
      the choice (only for providing the default value for CONFIG_LSM) in order
      to make sure that CONFIG_LSM reflects CONFIG_DEFAULT_SECURITY_* from their
      old kernel configs.
      
      Note that since TOMOYO can be fully stacked against the other legacy
      major LSMs, when it is selected, it explicitly disables the other LSMs
      to avoid them also initializing since TOMOYO does not expect this
      currently.

      A new dir entry can be created in get_subdir and its 'header->parent' is
      set to NULL.  Only after insert_header success, it will be set to 'dir',
      otherwise 'header->parent' is set to NULL and drop_sysctl_table is called.
      However in err handling path of get_subdir, drop_sysctl_table also be
      called on 'new->header' regardless its value of parent pointer.  Then
      put_links is called, which triggers NULL-ptr deref when access member of
      header->parent.
      
      In fact we have multiple error paths which call drop_sysctl_table() there,
      upon failure on insert_links() we also call drop_sysctl_table().And even
      in the successful case on __register_sysctl_table() we still always call
      drop_sysctl_table().This patch fix it.
