  • dma_addr_t's can be either u32 or u64 depending on a CONFIG option.

    There are a few hundred dma_addr_t's printed via either cast to unsigned
    long long, unsigned long or no cast at all.

    Add %pad to be able to emit them without the cast.

    Update Documentation/printk-formats.txt too.

  • New formats: %p[dD][234]?. The next pointer is interpreted as struct dentry *
    or struct file * resp. ('d' => dentry, 'D' => file) and the last component(s)
    of pathname are printed (%pd => just the last one, %pd2 => the last two, etc.)

  • Now all 64-bit architectures have been converted to int-ll64.h in kernel
    space, casting to (unsigned) long long is no longer needed when formatting
    u64/s64.

    For backwards compatibility, alpha, ia64, mips64, and powerpc64 still use
    int-l64.h in userspace.

  • In order to avoid making code that deals with printing both, IPv4 and
    IPv6 addresses, unnecessary complicated as for example ...

    if (sa.sa_family == AF_INET6)
    printk("... %pI6 ...", ..sin6_addr);
    else
    printk("... %pI4 ...", ..sin_addr.s_addr);

    ... it would be better to introduce a format specifier that can deal
    with those kind of situations internally; just as we have a "struct
    sockaddr" for generic mapping into "struct sockaddr_in" or "struct
    sockaddr_in6" as e.g. done in "union sctp_addr". Then, we could
    reduce the above statement into something like:

    printk("... %pIS ..", &sockaddr);

    In case our pointer is NULL, pointer() then deals with that already at
    an earlier point in time internally. While we're at it, support for both
    %piS/%pIS, where 'S' stands for sockaddr, comes (almost) for free.

    Additionally to that, postfix specifiers 'p', 'f' and 's' are supported
    as suggested and initially implemented in 2009 by Joe Perches [1].
    Handling of those additional specifiers orientate on the initial RFC that
    was proposed. Also we support IPv6 compressed format specified by 'c' and
    various other IPv4 extensions as stated in the documentation part.

    Likely, there are many other areas than just SCTP in the kernel to make
    use of this extension as well.

  • Pull fixup for trivial branch from Jiri Kosina:
    "Unfortunately I made a mistake when merging into for-linus branch, and
    omitted one pre-requisity patch for a few other patches (which have
    been Acked by the appropriate maintainers) in the series. Mea culpa
    maxima, sorry for that."

    The trivial branch added %pSR usage before actually teaching vsnprintf()
    about the 'R' part of %pSR. The 'R' causes the symbol translation to do
    a "__builtin_extract_return_addr()" before symbol lookup.

    That said, on most architectures __builtin_extract_return_addr() isn't
    likely to do anything special, so it probably is not normally
    noticeable.

    * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/trivial:
    vsprintf: Add extension %pSR - print_symbol replacement

    Linus Torvalds
     
  • print_symbol takes a long and converts it to a function
    name and offset. %pS does something similar, but doesn't
    translate the address via __builtin_extract_return_addr.
    %pSR does the translation.

    This will enable replacing multiple calls like
    printk(...);
    printk_symbol(addr);
    printk("\n");
    with a single non-interleavable in dmesg
    printk("... %pSR\n", (void *)addr);

    Update documentation too.

  • Add the %pa format specifier for printing a phys_addr_t type and its
    derivative types (such as resource_size_t), since the physical address
    size on some platforms can vary based on build options, regardless of
    the native integer type.

  • There are many places in the kernel where the drivers print small buffers
    as a hex string. This patch adds a support of the variable width buffer
    to print it as a hex string with a delimiter. The idea came from Pavel
    Roskin here: http://www.digipedia.pl/usenet/thread/18835/17449/

    Sample output of
    pr_info("buf[%d:%d] %*phC\n", from, len, len, &buf[from]);
    could be look like this:
    [ 0.726130] buf[51:8] e8:16:b6:ef:e3:74:45:6e
    [ 0.750736] buf[59:15] 31:81:b8:3f:35:49:06:ae:df:32:06:05:4a:af:55
    [ 0.757602] buf[17:5] ac:16:d5:2c:ef
