      GPIO: gpio-pxa: fix building without CONFIG_OF · f43e04ec
      Arnd Bergmann authored
      Commit 72121572 ("GPIO: gpio-pxa: fix devicetree functions") added an
      "xlate" function pointer to the irq_domain_ops, but this function is nor
      declared or defined anywhere when CONFIG_OF is disabled, causing the
      build error:
      
        drivers/gpio/gpio-pxa.c:532:11: error: 'irq_domain_xlate_twocell' undeclared here (not in a function)
      
      Extending the DT-only code section to cover the irq_domain_ops and the
      pxa_gpio_dt_ids solves this problem and makes it clearer which code is
      actually used without DT.

      af_packet: remove BUG statement in tpacket_destruct_skb · 7f5c3e3a
      danborkmann@iogearbox.net authored
      Here's a quote of the comment about the BUG macro from asm-generic/bug.h:
      
       Don't use BUG() or BUG_ON() unless there's really no way out; one
       example might be detecting data structure corruption in the middle
       of an operation that can't be backed out of.  If the (sub)system
       can somehow continue operating, perhaps with reduced functionality,
       it's probably not BUG-worthy.
      
       If you're tempted to BUG(), think again:  is completely giving up
       really the *only* solution?  There are usually better options, where
       users don't need to reboot ASAP and can mostly shut down cleanly.
      
      In our case, the status flag of a ring buffer slot is managed from both sides,
      the kernel space and the user space. This means that even though the kernel
      side might work as expected, the user space screws up and changes this flag
      right between the send(2) is triggered when the flag is changed to
      TP_STATUS_SENDING and a given skb is destructed after some time. Then, this
      will hit the BUG macro. As David suggested, the best solution is to simply
      remove this statement since it cannot be used for kernel side internal
      consistency checks. I've tested it and the system still behaves /stable/ in
      this case, so in accordance with the above comment, we should rather remove it.

      printk: Fix calculation of length used to discard records · e3756477
      Jeff Mahoney authored
      While tracking down a weird buffer overflow issue in a program that
      looked to be sane, I started double checking the length returned by
      syslog(SYSLOG_ACTION_READ_ALL, ...) to make sure it wasn't overflowing
      the buffer.
      
      Sure enough, it was.  I saw this in strace:
      
        11339 syslog(SYSLOG_ACTION_READ_ALL, "<5>[244017.708129] REISERFS (dev"..., 8192) = 8279
      
      It turns out that the loops that calculate how much space the entries
      will take when they're copied don't include the newlines and prefixes
      that will be included in the final output since prev flags is passed as
      zero.
      
      This patch properly accounts for it and fixes the overflow.
