      null_blk: suppress invalid partition info · 227290b4
      Jens Axboe 提交于
      null_blk is partitionable, but it doesn't store any of the info. When
      it is loaded, you would normally see:
      
      [1226739.343608]  nullb0: unknown partition table
      [1226739.343746]  nullb1: unknown partition table
      
      which can confuse some people. Add the appropriate gendisk flag
      to suppress this info.

      brd: Request from fdisk 4k alignment · c8fa3173
      Boaz Harrosh 提交于
      Because of the direct_access() API which returns a PFN. partitions
      better start on 4K boundary, else offset ZERO of a partition will
      not be aligned and blk_direct_access() will fail the call.
      
      By setting blk_queue_physical_block_size(PAGE_SIZE) we can communicate
      this to fdisk and friends.
      
      The call to blk_queue_physical_block_size() is harmless and will
      not affect the Kernel behavior in any way. It is only for
      communication to user-mode.
      
      before this patch running fdisk on a default size brd of 4M
      the first sector offered is 34 (BAD), but after this patch it
      will be 40, ie 8 sectors aligned. Also when entering some random
      partition sizes the next partition-start sector is offered 8 sectors
      aligned after this patch. (Please note that with fdisk the user
      can still enter bad values, only the offered default values will
      be correct)
      
      Note that with bdev-size > 4M fdisk will try to align on a 1M
      boundary (above first-sector will be 2048), in any case.

      brd: Fix all partitions BUGs · 937af5ec
      Boaz Harrosh 提交于
      This patch fixes up brd's partitions scheme, now enjoying all worlds.
      
      The MAIN fix here is that currently, if one fdisks some partitions,
      a BAD bug will make all partitions point to the same start-end sector
      ie: 0 - brd_size And an mkfs of any partition would trash the partition
      table and the other partition.
      
      Another fix is that "mount -U uuid" will not work if show_part was not
      specified, because of the GENHD_FL_SUPPRESS_PARTITION_INFO flag.
      We now always load without it and remove the show_part parameter.
      
      [We remove Dmitry's new module-param part_show it is now always
       show]
      
      So NOW the logic goes like this:
      * max_part - Just says how many minors to reserve between ramX
        devices. In any way, there can be as many partition as requested.
        If minors between devices ends, then dynamic 259-major ids will
        be allocated on the fly.
        The default is now max_part=1, which means all partitions devt(s)
        will be from the dynamic (259) major-range.
        (If persistent partition minors is needed use max_part=X)
        For example with /dev/sdX max_part is hard coded 16.
      
      * Creation of new devices on the fly still/always work:
        mknod /path/devnod b 1 X
        fdisk -l /path/devnod
        Will create a new device if [X / max_part] was not already
        created before. (Just as before)
      
        partitions on the dynamically created device will work as well
        Same logic applies with minors as with the pre-created ones.
      
      TODO: dynamic grow of device size. So each device can have it's
            own size.

      According to hda specification stream tag must be unique throughout the

      which is already in use by an input stream. This change is necessary
      to support HW which provides a total of more than 15 stream DMA engines
      which with legacy implementation causes an overflow on SDxCTL.STRM
      field (and the whole SDxCTL register) and as a result usage of
      Reserved value 0 in the SDxCTL.STRM field which confuses HDA controller.

      A regression was caused by commit 780a7654:
      	 audit: Make testing for a valid loginuid explicit.
      (which in turn attempted to fix a regression caused by e1760bd5)
      
      When audit_krule_to_data() fills in the rules to get a listing, there was a
      missing clause to convert back from AUDIT_LOGINUID_SET to AUDIT_LOGINUID.
      
      This broke userspace by not returning the same information that was sent and
      expected.
      
      The rule:
      	auditctl -a exit,never -F auid=-1
      gives:
      	auditctl -l
      		LIST_RULES: exit,never f24=0 syscall=all
      when it should give:
      		LIST_RULES: exit,never auid=-1 (0xffffffff) syscall=all
      
      Tag it so that it is reported the same way it was set.  Create a new
      private flags audit_krule field (pflags) to store it that won't interact with
      the public one from the API.

      arm64: kernel: fix __cpu_suspend mm switch on warm-boot · f43c2718
      Lorenzo Pieralisi 提交于
      On arm64 the TTBR0_EL1 register is set to either the reserved TTBR0
      page tables on boot or to the active_mm mappings belonging to user space
      processes, it must never be set to swapper_pg_dir page tables mappings.
      
      When a CPU is booted its active_mm is set to init_mm even though its
      TTBR0_EL1 points at the reserved TTBR0 page mappings. This implies
      that when __cpu_suspend is triggered the active_mm can point at
      init_mm even if the current TTBR0_EL1 register contains the reserved
      TTBR0_EL1 mappings.
      
      Therefore, the mm save and restore executed in __cpu_suspend might
      turn out to be erroneous in that, if the current->active_mm corresponds
      to init_mm, on resume from low power it ends up restoring in the
      TTBR0_EL1 the init_mm mappings that are global and can cause speculation
      of TLB entries which end up being propagated to user space.
      
      This patch fixes the issue by checking the active_mm pointer before
      restoring the TTBR0 mappings. If the current active_mm == &init_mm,
      the code sets the TTBR0_EL1 to the reserved TTBR0 mapping instead of
      switching back to the active_mm, which is the expected behaviour
      corresponding to the TTBR0_EL1 settings when __cpu_suspend was entered.
