NETFILTER: tcp conntrack: fix IP_CT_TCP_FLAG_CLOSE_INIT value

2007-03-24T20:22:57+00:00

IP_CT_TCP_FLAG_CLOSE_INIT is a flag and should have a value of 0x4 instead
of 0x3, which is IP_CT_TCP_FLAG_WINDOW_SCALE | IP_CT_TCP_FLAG_SACK_PERM.

NETFILTER: Fix iptables ABI breakage on (at least) CRIS

2007-03-24T20:22:09+00:00

With the introduction of x_tables we accidentally broke compatibility
by defining IPT_TABLE_MAXNAMELEN to XT_FUNCTION_MAXNAMELEN instead of
XT_TABLE_MAXNAMELEN, which is two bytes larger.

On most architectures it doesn't really matter since we don't have
any tables with names that long in the kernel and the structure
layout didn't change because of alignment requirements of following
members. On CRIS however (and other architectures that don't align
data) this changed the structure layout and thus broke compatibility
with old iptables binaries.

Changing it back will break compatibility with binaries compiled
against recent kernels again, but since the breakage has only been
there for three releases this seems like the better choice.

NETFILTER: arp_tables: fix userspace compilation

The included patch translates arpt_counters to xt_counters, making
userspace arptables compile against recent kernels.

make ppc64 current preempt-safe

2007-03-09T07:42:48+00:00

Repeated -j20 kernel builds on a G5 Quad running an SMP PREEMPT kernel
would often collapse within a day, some exec failing with "Bad address".
In each case examined, load_elf_binary was doing a kernel_read, but
generic_file_aio_read's access_ok saw current->thread.fs.seg as USER_DS
instead of KERNEL_DS.

objdump of filemap.o shows gcc 4.1.0 emitting "mr r5,r13 ... ld r9,416(r5)"
here for get_paca()->__current, instead of the expected and much more usual
"ld r9,416(r13)"; I've seen other gcc4s do the same, but perhaps not gcc3s.

So, if the task is preempted and rescheduled on a different cpu in between
the mr and the ld, r5 will be looking at a different paca_struct from the
one it's now on, pick up the wrong __current, and perhaps the wrong seg.
Presumably much worse could happen elsewhere, though that split is rare.

Other architectures appear to be safe (x86_64's read_pda is more limiting
than get_paca), but ppc64 needs to force "current" into one instruction.

hwmon: Refactor SENSOR_DEVICE_ATTR_2

2007-02-26T02:37:36+00:00

This patch refactors SENSOR_DEVICE_ATTR_2 macro, following pattern set by
SENSOR_ATTR.  First it creates a new macro SENSOR_ATTR_2() which expands
to an initialization expression, then it uses that in SENSOR_DEVICE_ATTR_2,
which declares and initializes a struct sensor_device_attribute_2.

hwmon: Allow sensor attributes arrays

2007-02-26T02:31:01+00:00

This patch refactors SENSOR_DEVICE_ATTR macro.  First it creates a new
macro SENSOR_ATTR() which expands to an initialization expression, then
it uses that in SENSOR_DEVICE_ATTR, which declares and initializes a
struct sensor_device_attribute.

IOW, SENSOR_ATTR() imitates __ATTR() in include/linux/device.h.

that at least on Supermicro H8SSL it uses non-standard SMBHSTCFG = 3

[TCP]: struct tcp_sack_block annotations

2007-02-14T12:58:42+00:00

Some of the instances of tcp_sack_block are host-endian, some - net-endian.
Define struct tcp_sack_block_wire identical to struct tcp_sack_block
with u32 replaced with __be32; annotate uses of tcp_sack_block replacing
net-endian ones with tcp_sack_block_wire.  Change is obviously safe since
for cc(1) __be32 is typedefed to u32.
