10 years agoword-at-a-time: avoid undefined behaviour in zero_bytemask macro
Will Deacon [Wed, 23 Apr 2014 16:52:52 +0000 (17:52 +0100)]
word-at-a-time: avoid undefined behaviour in zero_bytemask macro

The asm-generic, big-endian version of zero_bytemask creates a mask of
bytes preceding the first zero-byte by left shifting ~0ul based on the
position of the first zero byte.

Unfortunately, if the first (top) byte is zero, the output of
prep_zero_mask has only the top bit set, resulting in undefined C
behaviour as we shift left by an amount equal to the width of the type.
As it happens, GCC doesn't manage to spot this through the call to fls(),
but the issue remains if architectures choose to implement their shift
instructions differently.

An example would be arch/arm/ (AArch32), where LSL Rd, Rn, #32 results
in Rd == 0x0, whilst on arch/arm64 (AArch64) LSL Xd, Xn, #64 results in
Xd == Xn.

Rather than check explicitly for the problematic shift, this patch adds
an extra shift by 1, replacing fls with __fls. Since zero_bytemask is
never called with a zero argument (has_zero() is used to check the data
first), we don't need to worry about calling __fls(0), which is
undefined.

Btrfs: limit the path size in send to PATH_MAX

fs_path_ensure_buf is used to make sure our path buffers for
send are big enough for the path names as we construct them.
The buffer size is limited to 32K by the length field in
the struct.

But bugs in the path construction can end up trying to build
a huge buffer, and we'll do invalid memmmoves when the
buffer length field wraps.

This patch is step one, preventing the overflows.

10 years agomm: split 'tlb_flush_mmu()' into tlb flushing and memory freeing parts

mm: split 'tlb_flush_mmu()' into tlb flushing and memory freeing parts

The mmu-gather operation 'tlb_flush_mmu()' has done two things: the
actual tlb flush operation, and the batched freeing of the pages that
the TLB entries pointed at.

This splits the operation into separate phases, so that the forced
batched flushing done by zap_pte_range() can now do the actual TLB flush
while still holding the page table lock, but delay the batched freeing
of all the pages to after the lock has been dropped.

This in turn allows us to avoid a race condition between
set_page_dirty() (as called by zap_pte_range() when it finds a dirty
shared memory pte) and page_mkclean(): because we now flush all the
dirty page data from the TLB's while holding the pte lock,
page_mkclean() will be held up walking the (recently cleaned) page
tables until after the TLB entries have been flushed from all CPU's.

xhci: Switch Intel Lynx Point ports to EHCI on shutdown.

The same issue like with Panther Point chipsets. If the USB ports are
switched to xHCI on shutdown, the xHCI host will send a spurious interrupt,
which will wake the system. Some BIOS have work around for this, but not all.
One example is Compulab's mini-desktop, the Intense-PC2.

The bug can be avoided if the USB ports are switched back to EHCI on
shutdown.

10 years agousb: xhci: Prefer endpoint context dequeue pointer over stopped_trb
Julius Werner [Fri, 25 Apr 2014 16:20:13 +0000 (19:20 +0300)]
usb: xhci: Prefer endpoint context dequeue pointer over stopped_trb

We have observed a rare cycle state desync bug after Set TR Dequeue
Pointer commands on Intel LynxPoint xHCs (resulting in an endpoint that
doesn't fetch new TRBs and thus an unresponsive USB device). It always
triggers when a previous Set TR Dequeue Pointer command has set the
pointer to the final Link TRB of a segment, and then another URB gets
enqueued and cancelled again before it can be completed. Further
investigation showed that the xHC had returned the Link TRB in the TRB
Pointer field of the Transfer Event (CC == Stopped -- Length Invalid),
but when xhci_find_new_dequeue_state() later accesses the Endpoint
Context's TR Dequeue Pointer field it is set to the first TRB of the
next segment.

The driver expects those two values to be the same in this situation,
and uses the cycle state of the latter together with the address of the
former. This should be fine according to the XHCI specification, since
the endpoint ring should be stopped when returning the Transfer Event
and thus should not advance over the Link TRB before it gets restarted.
However, real-world XHCI implementations apparently don't really care
that much about these details, so the driver should follow a more
defensive approach to try to work around HC spec violations.

This patch removes the stopped_trb variable that had been used to store
the TRB Pointer from the last Transfer Event of a stopped TRB. Instead,
xhci_find_new_dequeue_state() now relies only on the Endpoint Context,
requiring a small amount of additional processing to find the virtual
address corresponding to the TR Dequeue Pointer. Some other parts of the
function were slightly rearranged to better fit into this model.

This patch should be backported to kernels as old as 2.6.31 that contain
the commit ae636747146ea97efa18e04576acd3416e2514f5 "USB: xhci: URB

introduced a fix for checking PJ4 cpuid to not use PJ4 specific

Unfortunately, this in turn broke Marvell Armada 370/XP, both

of only checking for cpuid, which may not be sufficient to

can be checked by enabling and reading the Coprocessor ID
register (wCID, register 0 of CP1).

Therefore this adds an explicit check for the presence and correct
wCID value, before enabling iWMMXt capabilities. As a bonus, also
print the iWMMXt version of a detected coprocessor.

This has been tested to properly detect iWMMXt presence/absence on:

- PJ4B, CPUID 0x561f5811: Marvell Armada 370, no iWMMXt
