  • With dynamic function tracer, by default, _mcount is defined as an
    "empty" function, it returns directly without any more action . When
    enabling it in user-space, it will jump to a real tracing
    function(ftrace_caller), and do the real job for us.

    Differ from the static function tracer, dynamic function tracer provides
    two functions ftrace_make_call()/ftrace_make_nop() to enable/disable the
    tracing of some indicated kernel functions(set_ftrace_filter).

    In the -v4 version, the implementation of this support is basically the same as
    X86 version does: _mcount is implemented as an empty function and ftrace_caller
    is implemented as a real tracing function respectively.

    But in this version, to support module tracing with the help of
    -mlong-calls in arch/mips/Makefile:

    MODFLAGS += -mlong-calls.

    The stuff becomes a little more complex. We need to cope with two
    different type of calling to _mcount.

    For the kernel part, the calling to _mcount(result of "objdump -hdr
    vmlinux"). is like this:

    108: 03e0082d move at,ra
    10c: 0c000000 jal 0
    10c: R_MIPS_26 _mcount
    10c: R_MIPS_NONE *ABS*
    10c: R_MIPS_NONE *ABS*
    110: 00020021 nop

    For the module with -mlong-calls, it looks like this:

    c: 3c030000 lui v1,0x0
    c: R_MIPS_HI16 _mcount
    c: R_MIPS_NONE *ABS*
    c: R_MIPS_NONE *ABS*
    10: 64630000 daddiu v1,v1,0
    10: R_MIPS_LO16 _mcount
    10: R_MIPS_NONE *ABS*
    10: R_MIPS_NONE *ABS*
    14: 03e0082d move at,ra
    18: 0060f809 jalr v1

    In the kernel version, there is only one "_mcount" string for every
    kernel function, so, we just need to match this one in mcount_regex of
    scripts/recordmcount.pl, but in the module version, we need to choose
    one of the two to match. Herein, I choose the first one with
    "R_MIPS_HI16 _mcount".

    and In the kernel verion, without module tracing support, we just need
    to replace "jal _mcount" by "jal ftrace_caller" to do real tracing, and
    filter the tracing of some kernel functions via replacing it by a nop
    instruction.

    but as we have described before, the instruction "jal ftrace_caller" only left
    32bit length for the address of ftrace_caller, it will fail when calling from
    the module space. so, herein, we must replace something else.

    the basic idea is loading the address of ftrace_caller to v1 via changing these
    two instructions:

    lui v1,0x0
    addiu v1,v1,0

    If we want to enable the tracing, we need to replace the above instructions to:

    lui v1, HI_16BIT_ftrace_caller
    addiu v1, v1, LOW_16BIT_ftrace_caller

    If we want to stop the tracing of the indicated kernel functions, we
    just need to replace the "jalr v1" to a nop instruction. but we need to
    replace two instructions and encode the above two instructions
    oursevles.

    Is there a simpler solution? Yes! Here it is, in this version, we put _mcount
    and ftrace_caller together, which means the address of _mcount and
    ftrace_caller is the same:

    _mcount:
    ftrace_caller:
    j ftrace_stub
    nop

    ...(do real tracing here)...

    ftrace_stub:
    jr ra
    move ra, at

    By default, the kernel functions call _mcount, and then jump to ftrace_stub and
    return. and when we want to do real tracing, we just need to remove that "j
    ftrace_stub", and it will run through the two "nop" instructions and then do
    the real tracing job.

    what about filtering job? we just need to do this:

    lui v1, hi_16bit_of_mcount b 1f (0x10000004)
    addiu v1, v1, low_16bit_of_mcount
    move at, ra
    jalr v1
    nop
    1f: (rec->ip + 12)

    In linux-mips64, there will be some local symbols, whose name are
    prefixed by $L, which need to be filtered. thanks goes to Steven for
    writing the mips64-specific function_regex.

    In a conclusion, with RISC, things becomes easier with such a "stupid"
    trick, RISC is something like K.I.S.S, and also, there are lots of
    "simple" tricks in the whole ftrace support, thanks goes to Steven and
    the other folks for providing such a wonderful tracing framework!

  • Despite being unused these should also get a CRC calculated.
    Primarily I view this as a consistency thing. But I also think this is
    one of the reasons why __crc_* need to be weak (which I think should be
    avoided, and hence we should have the goal to eliminate this so that
    failure to calculate a proper CRC for a symbol causes the build to fail).

  • Running "make deb-pkg" requires setting KBUILD_PKG_ROOTCMD or
    becoming root oneself or it errors out. Unless already running
    as root or KBUILD_PKG_ROOTCMD is already set, use fakeroot as a
    good default.

    With this patch applied, you can run "make oldconfig deb-pkg" as
    an ordinary user to build a binary package for an updated kernel
    tree and it should just work.

    fakeroot is too zealous by default in treating files as owned by
    root. Its wrapped stat() sets st_uid and st_gid to 0 for all
    files, which causes Git to go on a wild goose chase if
    CONFIG_LOCALVERSION_AUTO is set, checking if any file's content
    has changed along with its stat information. Avoid this by
    telling fakeroot to use the actual owner and group for
    preexisting files, by passing it the -u option.

  • Let the deb-pkg target acquire (fake) root privileges before
    running commands that need them. Without such privileges,
    deb-pkg errors out because chown fails.

    The new KBUILD_PKG_ROOTCMD variable, if defined, is used as a
    command to run other commands with possibly fake elevated
    privileges. Since this is not needed for the tar-pkg and rpm-pkg
    targets, it is only used by deb-pkg. If it is not defined, the
    behavior is as before, and the user will have to rerun make as
    root.

    In other words, as a shortcut, instead of running 'make oldconfig &&
    make && fakeroot -u make deb-pkg', one can use the single command
    'make oldconfig deb-pkg KBUILD_PKG_ROOTCMD="fakeroot -u"'.

  • The current code to generate usb modaliases from usb_device_id assumes
    that the device's bcdDevice descriptor will actually be in BCD format.
    While this should be a sane assumption, some devices don't follow spec
    and just use plain old hex. This causes drivers for these devices to
    generate invalid modalias lines which will never actually match for the
    hardware.

    The following patch adds hex support for bcdDevice in file2alias.c by
    detecting when a driver uses a hex formatted bcdDevice_(lo|hi) and
    adjusts the output to hex format accordingly.

    Drivers for devices which have bcdDevice conforming to BCD will have no
    change in modalias output. Drivers for devices which don't conform
    (i.e. ibmcam) should now generate valid modaliases.

  • The introduction of the new 'DECLARE_EVENT_CLASS()' obviates the
    need for the 'TRACE_EVENT()' macro in some cases. Thus, docbook
    style comments that used to live with 'TRACE_EVENT()' are now
    moved to 'DEFINE_EVENT()'. Thus, we need to make the docbook
    system understand the new 'DEFINE_EVENT()' macro. In addition
    I've tried to futureproof the patch, by also adding support for
    'DEFINE_SINGLE_EVENT()', since there has been discussion about
    renaming: TRACE_EVENT() -> DEFINE_SINGLE_EVENT().

    Without this patch the tracepoint docbook fails to build.

    I've verified that this patch correctly builds the tracepoint
    docbook which currently covers signals, and irqs.

    Changes in v2:
    - properly indent perl 'if' statements

  • If a permission name is long enough the selinux class definition generation
    tool will go into a infinite loop. This is because it's macro max() is
    fooled into thinking it is dealing with unsigned numbers. This patch makes
    sure the macro always uses signed number so 1 > -1.

  • When the output directory is something other than the kernel source,
    the streamline_config script gets confused. This patch passes in the
    source directory to the script so that it can find the proper files.

  • If the user has an older version of objcopy, that can not handle
    converting local symbols to global and vice versa, then some
    functions will not be part of the dynamic function tracer. The current
    code in recordmcount.pl will print a warning in this case. Unfortunately,
    there exists lots of files that may have this issue with older objcopys
    and this will cause a warning for every file compiled with this
    issue.

    This patch solves this overwhelming output by creating a
    .tmp_quiet_recordmcount file on the first instance the warning is
    encountered. The warning will not print if this file exists.

    The temp file is deleted at the beginning of the compile to ensure that
    the warning will happen once again on new compiles (because the issue
    is still present).
