  • 881d966b4   [NET]: Make the device list and device lookups per namespace. ... Browse Code »

    This patch makes most of the generic device layer network
    namespace safe. This patch makes dev_base_head a
    network namespace variable, and then it picks up
    a few associated variables. The functions:
    dev_getbyhwaddr
    dev_getfirsthwbytype
    dev_get_by_flags
    dev_get_by_name
    __dev_get_by_name
    dev_get_by_index
    __dev_get_by_index
    dev_ioctl
    dev_ethtool
    dev_load
    wireless_process_ioctl

    were modified to take a network namespace argument, and
    deal with it.

    vlan_ioctl_set and brioctl_set were modified so their
    hooks will receive a network namespace argument.

    So basically anthing in the core of the network stack that was
    affected to by the change of dev_base was modified to handle
    multiple network namespaces. The rest of the network stack was
    simply modified to explicitly use &init_net the initial network
    namespace. This can be fixed when those components of the network
    stack are modified to handle multiple network namespaces.

    For now the ifindex generator is left global.

    Fundametally ifindex numbers are per namespace, or else
    we will have corner case problems with migration when
    we get that far.

    At the same time there are assumptions in the network stack
    that the ifindex of a network device won't change. Making
    the ifindex number global seems a good compromise until
    the network stack can cope with ifindex changes when
    you change namespaces, and the like.

    Make some offending drivers depend on it and set CONFIG_ARCH_NO_VIRT_TO_BUS
    for ppc64 so that we don't build those drivers.

    This gets PowerPC allmodconfig and allyesconfig much closer to building.

    lanai, change VENDOR to DEVICE

    There were 2 bad named macros in pci_ids (LANAI 2 and IHB). Rename it to
    DEVICE, because it's device id. Also make some cleanpu in pci_device_id
    table (use PCI_VDEVICE).

  • 44c10138f   PCI: Change all drivers to use pci_device->revision ... Browse Code »
    88

    Instead of all drivers reading pci config space to get the revision
    ID, they can now use the pci_device->revision member.

    This exposes some issues where drivers where reading a word or a dword
    for the revision number, and adding useless error-handling around the
    read. Some drivers even just read it for no purpose of all.

    In devices where the revision ID is being copied over and used in what
    appears to be the equivalent of hotpath, I have left the copy code
    and the cached copy as not to influence the driver's performance.

    Compile tested with make all{yes,mod}config on x86_64 and i386.

  • 0da2f0f16   potential compiler error, irqfunc caller sites update ... Browse Code »

    In 7d12e780e003f93433d49ce78cfedf4b4c52adc5 David Howells performed
    this evolution:
    "IRQ: Maintain regs pointer globally rather than passing to IRQ handlers"

    He correctly updated many of the function definitions that were using this
    extra regs pointer parameter but forgot to update some caller sites of
    those functions. The reason the modifications was not properly done on all
    drivers is that some drivers were rarely compiled because they are for
    AMIGA, or that some code sites were inside #ifdefs where the option is not
    set or inside #if 0.

    Here is the semantic patch that found the occurences
    and fixed the problem.

    @ rule1 @
    identifier fn;
    identifier irq, dev_id;
    typedef irqreturn_t;

  • 59faba1b3   Fix Kconfig dependency problems wrt boolean menuconfigs ... Browse Code »

    If one has a dependency chain (tristate)FOO depends on (bool)BAR depends on
    (tristate)BAZ, build problems will result. If BAZ=m, then BAR can be set
    y, which allows FOO=y. It's possible to have FOO=y && BAZ=m, which
    wouldn't be allowed if FOO depended directly on BAZ. In effect, the bool
    promotes the tristate from m to y.

    This ends up causing a problem with several menuconfigs that look like:

    menuconfig BAR
    bool
    depends on BAZ [tristate]
    if BAR
    config FOO
    tristate
    endif

    The solution used here is to add the dependencies of BAR to the if
    statement, so that items in the if block will gain a direct
    non-bool-promoted dependency on BAZ. This is how it would work if a menu
    was used instead of an if block.

  • b206a65d6   [ATM]: Fix warning. ... Browse Code »

    The compiler warning

    drivers/atm/firestream.c: In function ‘top_off_fp’:
    drivers/atm/firestream.c:1505: warning: cast to pointer from integer of different size

    does indicate a bug, albeit a minor one. Fixed, by using a 32-bit
    temporary prior to the call to bus_to_virt().

    The larger bug is still present: the entire driver assumes that machine
    pointers are 32-bit, as it stores pointers in 32-bit hardware registers.
    This is obvious to anyone who knows the driver well, but for the casual
    readers it is helpfully noted with FIXME.

  • 6473d160b   PCI: Cleanup the includes of <linux/pci.h> ... Browse Code »

    I noticed that many source files include while they do
    not appear to need it. Here is an attempt to clean it all up.

    In order to find all possibly affected files, I searched for all
    files including but without any other occurence of "pci"
    or "PCI". I removed the include statement from all of these, then I
    compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
    false positives manually.

    My tests covered 66% of the affected files, so there could be false
    positives remaining. Untested files are:

    arch/alpha/kernel/err_common.c
    arch/alpha/kernel/err_ev6.c
    arch/alpha/kernel/err_ev7.c
    arch/ia64/sn/kernel/huberror.c
    arch/ia64/sn/kernel/xpnet.c

    I would welcome test reports for these files. I am fine with removing
    the untested files from the patch if the general opinion is that these
    changes aren't safe. The tested part would still be nice to have.

    Note that this patch depends on another header fixup patch I submitted
    to LKML yesterday:

  • cd354f1ae   [PATCH] remove many unneeded #includes of sched.h ... Browse Code »

    After Al Viro (finally) succeeded in removing the sched.h #include in module.h
    recently, it makes sense again to remove other superfluous sched.h includes.
    There are quite a lot of files which include it but don't actually need
    anything defined in there. Presumably these includes were once needed for
    macros that used to live in sched.h, but moved to other header files in the
    course of cleaning it up.

    To ease the pain, this time I did not fiddle with any header files and only
    removed #includes from .c-files, which tend to cause less trouble.

    Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
    arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
    allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
    configs in arch/arm/configs on arm. I also checked that no new warnings were
    introduced by the patch (actually, some warnings are removed that were emitted
    by unnecessarily included header files).
