MIPS: BPF: Fix stack pointer allocation

Fix stack pointer offset which could potentially corrupt
argument registers in the previous frame. The calculated offset
reflects the size of all the registers we need to preserve so there
is no need for this erroneous subtraction.

[ralf@linux-mips.org: Fixed conflict due to only applying this fix part
of the entire series as part of 4.1 fixes.]

iscsi_ibft: filter null v4-mapped v6 addresses

I've had reports of UEFI platforms failing iSCSI boot in various
configurations, that ended up being caused by network initialization
scripts getting tripped up by unexpected null addresses (0.0.0.0) being
reported for gateways, dhcp servers, and dns servers.

The tianocore EDK2 iSCSI driver generates an iBFT table that always uses
IPv4-mapped IPv6 addresses for the NIC structure fields.  This results
in values that are "not present or not specified" being reported as
::ffff:0.0.0.0 rather than all zeros as specified.

The iscsi_ibft module filters unspecified fields from the iBFT from
sysfs, preventing userspace from using invalid values and making it easy
to check for the presence of a value.  This currently fails in regard to
these mapped null addresses.

In order to remain consistent with how the iBFT information is exposed,
we should accommodate the behavior of the tianocore iSCSI driver as it's
already in the wild in a large number of servers.

Tested under qemu using an OVMF build of tianocore EDK2.

cannot be locked while disabled. Once locked, the drivers

vfs: read file_handle only once in handle_to_path

We used to read file_handle twice.  Once to get the amount of extra
bytes, and once to fetch the entire structure.

This may be problematic since we do size verifications only after the
first read, so if the number of extra bytes changes in userspace between
the first and second calls, we'll have an incoherent view of
file_handle.

Instead, read the constant size once, and copy that over to the final
structure without having to re-read it again.

9 years agox86/asm/irq: Stop relying on magic JMP behavior for early_idt_handlers
Andy Lutomirski [Fri, 22 May 2015 23:15:47 +0000 (16:15 -0700)]
x86/asm/irq: Stop relying on magic JMP behavior for early_idt_handlers

The early_idt_handlers asm code generates an array of entry
points spaced nine bytes apart.  It's not really clear from that
code or from the places that reference it what's going on, and
the code only works in the first place because GAS never
generates two-byte JMP instructions when jumping to global
labels.

Clean up the code to generate the correct array stride (member size)
explicitly. This should be considerably more robust against
screw-ups, as GAS will warn if a .fill directive has a negative
count.  Using '. =' to advance would have been even more robust
(it would generate an actual error if it tried to move
backwards), but it would pad with nulls, confusing anyone who
tries to disassemble the code.  The new scheme should be much
clearer to future readers.

While we're at it, improve the comments and rename the array and
common code.

Binutils may start relaxing jumps to non-weak labels.  If so,
this change will fix our build, and we may need to backport this
change.

Revert "iommu/amd: Don't allocate with __GFP_ZERO in alloc_coherent"

This reverts commit 5fc872c7323534e8f7dc21bab635e7a9b9659e07.

The DMA-API does not strictly require that the memory
returned by dma_alloc_coherent is zeroed out. For that
another function (dma_zalloc_coherent) should be used. But
all other x86 DMA-API implementation I checked zero out the
memory, so that some drivers rely on it and break when it is
not.

It seems the (driver-)world is not yet ready for this
change, so revert it.
