      crypto: skcipher - Fix crash on zero-length input · 0cabf2af
      Herbert Xu authored
      The skcipher walk interface doesn't handle zero-length input
      properly as the old blkcipher walk interface did.  This is due
      to the fact that the length check is done too late.
      
      This patch moves the length check forward so that it does the
      right thing.

      crypto: shash - Fix a sleep-in-atomic bug in shash_setkey_unaligned · 9039f3ef
      Jia-Ju Bai authored
      The SCTP program may sleep under a spinlock, and the function call path is:
      sctp_generate_t3_rtx_event (acquire the spinlock)
        sctp_do_sm
          sctp_side_effects
            sctp_cmd_interpreter
              sctp_make_init_ack
                sctp_pack_cookie
                  crypto_shash_setkey
                    shash_setkey_unaligned
                      kmalloc(GFP_KERNEL)
      
      For the same reason, the orinoco driver may sleep in interrupt handler,
      and the function call path is:
      orinoco_rx_isr_tasklet
        orinoco_rx
          orinoco_mic
            crypto_shash_setkey
              shash_setkey_unaligned
                kmalloc(GFP_KERNEL)
      
      To fix it, GFP_KERNEL is replaced with GFP_ATOMIC.
      This bug is found by my static analysis tool and my code review.

      crypto: stm32 - Try to fix hash padding · 532f419c
      Arnd Bergmann authored
      gcc warns that the length for the extra unaligned data in the hash
      function may be used unaligned. In theory this could happen if
      we pass a zero-length sg_list, or if sg_is_last() was never true:
      
      In file included from drivers/crypto/stm32/stm32-hash.c:23:
      drivers/crypto/stm32/stm32-hash.c: In function 'stm32_hash_one_request':
      include/uapi/linux/kernel.h:12:49: error: 'ncp' may be used uninitialized in this function [-Werror=maybe-uninitialized]
       #define __KERNEL_DIV_ROUND_UP(n, d) (((n) + (d) - 1) / (d))
      
      Neither of these can happen in practice, so the warning is harmless.
      
      However while trying to suppress the warning, I noticed multiple
      problems with that code:
      
      - On big-endian kernels, we byte-swap the data like we do for
        register accesses, however this is a data stream and almost
        certainly needs to use a single writesl() instead of series
        of writel() to give the correct hash.
      
      - If the length is not a multiple of four bytes, we skip the
        last word entirely, since we write the truncated length
        using stm32_hash_set_nblw().
      
      - If we change the code to round the length up rather than
        down, the last bytes contain stale data, so it needs some
        form of padding.
      
      This tries to address all four problems, by correctly
      initializing the length to zero, using endian-safe copy
      functions, adding zero-padding and passing the padded length.
      
      I have done no testing on this patch, so please review
      carefully and if possible test with an unaligned length
      and big-endian kernel builds.

      firmware: Restore support for built-in firmware · df85b2d7
      Markus Trippelsdorf authored
      Commit 5620a0d1 ("firmware: delete in-kernel firmware") removed the
      entire firmware directory.  Unfortunately it thereby also removed the
      support for built-in firmware.
      
      This restores the ability to build firmware directly into the kernel by
      pruning the original Makefile to the necessary minimum.  The default for
      EXTRA_FIRMWARE_DIR is now the standard directory /lib/firmware/.

      The driver doesn't support events from address families other than IPv4
      and IPv6, so ignore them. Otherwise, we risk queueing a work item before
      it's initialized.
      
      This can happen in case a VRF is configured when MROUTE_MULTIPLE_TABLES
      is enabled, as the VRF driver will try to add an l3mdev rule for the
      IPMR family.
