9 years agoARM: force dcache flush if dcache_dirty bit set
Nitin Gupta [Mon, 12 Oct 2009 08:50:23 +0000]
ARM: force dcache flush if dcache_dirty bit set

On ARM, update_mmu_cache() does dcache flush for a page only if
it has a kernel mapping (page_mapping(page) != NULL). The correct
behavior would be to force the flush based on dcache_dirty bit only.

One of the cases where present logic would be a problem is when
a RAM based block device[1] is used as a swap disk. In this case,
we would have in-memory data corruption as shown in steps below:

do_swap_page()
{
    - Allocate a new page (if not already in swap cache)
    - Issue read from swap disk
        - Block driver issues flush_dcache_page()
        - flush_dcache_page() simply sets PG_dcache_dirty bit and does not
          actually issue a flush since this page has no user space mapping yet.
    - Now, if swap disk is almost full, this newly read page is removed
      from swap cache and corrsponding swap slot is freed.
    - Map this page anonymously in user space.
    - update_mmu_cache()
        - Since this page does not have kernel mapping (its not in page/swap
          cache and is mapped anonymously), it does not issue dcache flush
          even if dcache_dirty bit is set by flush_dcache_page() above.

    <user now gets stale data since dcache was never flushed>
}

Same problem exists on mips too.

[1] example:
 - brd (RAM based block device)
 - ramzswap (RAM based compressed swap device)

Linus Torvalds [Sun, 11 Oct 2009 22:57:57 +0000]
Revert "USB: Work around BIOS bugs by quiescing USB controllers earlier"

This reverts commit db8be50c4307dac2b37305fc59c8dc0f978d09ea, as per

http://bugzilla.kernel.org/show_bug.cgi?id=14374
http://marc.info/?l=linux-kernel&m=125446885705223&w=4

We simply can't do the USB handoff at FIXUP_HEADER time, since it will
often require us to have valid IO mappings etc.  But that in turn
requires a whole different approach, not this trivial one-liner.

Maybe we could teach all the USB quirk handoff handlers to only do the
quirk if the device has all its registers set up (since if it isn't
initialized, it's unlikely to be active), but regardless that will need
a whole lot more code than just saying "let's do it really early".

The proper fix is almost certainly to just leave the legacy IOMMU
mappings active until after all devices have been initialized.

pci: increase alignment to make more space for hidden code

As reported in

http://bugzilla.kernel.org/show_bug.cgi?id=13940

on some system when acpi are enabled, acpi clears some BAR for some
devices without reason, and kernel will need to allocate devices for
them.  It then apparently hits some undocumented resource conflict,
resulting in non-working devices.

Try to increase alignment to get more safe range for unassigned devices.

ARM: 5756/1: ep93xx: introduce clk parent

The clock generation system in the ep93xx uses two external oscillator's
and two internal PLLs to derive all the internal clocks.  Many of these
internal clocks can be stopped to save power.

This introduces a "parent" hierarchy for the clocks so that the users
count can be correctly tracked for power management.

The "parent" for the video clock can either be one of the PLL outputs
or the external oscillator.  In order to correctly track the "parent"
for the video clock calc_clk_div() needed to be modified.  It now
returns an error code if the desired rate cannot be generated.

Alan Stern [Tue, 6 Oct 2009 18:07:57 +0000]
USB: storage: When a device returns no sense data, call it a Hardware Error

This patch (as1294) fixes a problem that has plagued users for several
kernel releases.  Some USB mass-storage devices don't return any sense
data when they encounter certain kinds of errors.  The SCSI layer
interprets this to mean that the operation should be retried, and the
same thing happens -- over and over again with no limit.  In some
circumstances (such as when a bus reset occurs) that is the right
thing to do, but not here.

The patch checks for this condition (a transport failure with no sense
data) and changes the result code to DID_ERROR and the sense code to
Hardware Error.  This does get only a limited number of retries, and
so the command will fail relatively quickly instead of getting stuck
in an infinite loop.

This fixes a large part of Bugzilla #14118.

USB: ftdi_sio: re-implement read processing

- Re-structure read processing.
 - Kill obsolete work queue and always push to tty in completion handler.
 - Use tty_insert_flip_string instead of per character push when
   possible.
 - Fix stalled-read regression in 2.6.31 by using urb status to
   determine when port is closed rather than port count.
 - Fix race with open/close by checking ASYNCB_INITIALIZED in
   unthrottle.
 - Kill private rx_flag and lock and use throttle flags in
   usb_serial_port instead.

USB: ftdi_sio: clean up read completion handler

Remove superfluous error checks in completion handler:

 - No need to check private data and urb pointers as we check urb-status
   before dereferencing priv (which is not freed until urb has been killed
   on close).
 - No need to check tty as it is checked again when processing.
 - No need to check urb->number_of_packets on bulk urb.

Note that both private data and tty are checked again before processing
(possibly from work queue which also is cancelled on close).

Serge E. Hallyn [Wed, 16 Sep 2009 21:27:41 +0000]
Staging: p9auth: a few fixes

1. The memory into which we copy 'u1@u2' needs space for u1, @,
u2, and a final \0 which strcat copies in.
2. Strsep changes the value of its first argument.  So use a
temporary variable to pass to it, so we pass the original
value to kfree!
3. Allocate an extra char to user_buf, because we need a trailing \0
since we later kstrdup it.

I am about to send out an LTP testcase for this driver, but
in addition the correctness of the hashing can be verified as
follows:

 #include <stdio.h>
 #include <stdlib.h>
 #include <unistd.h>

int main(int argc, char *argv[])
{
        char in[41], out[20];
        unsigned int v;
        int i, ret;

        ret = read(STDIN_FILENO, in, 40);
        if (ret != 40)
                exit(1);
        in[40] = '\0';
        for (i = 0; i < 20; i++) {
                sscanf(&in[2*i], "%02x", &v);
                out[i] = v;
        }
        write(STDOUT_FILENO, out, 20);
}

IRQ: Change __softirq_pending to unsigned int in asm-generic/hardirq.h.

("asm-generic: add generic versions of common headers") the generic

Which is different from other architectures for no apparent good reason
