2011-01-14ARM: 6624/1: fix dependency for CONFIG_SMP_ON_UPNicolas Pitre

Commit d30e45e (ARM: pgtable: switch order of Linux vs hardware page tables) introduced a pre-increment addressing offset which is out of range for Thumb-2. Thumb-2 only permits offsets <256.

2011-01-11ARM: 6619/1: nommu: avoid mapping vectors page when !CONFIG_MMUWill Deacon
When running without an MMU, we do not need to install a mapping for the vectors page. Attempting to do so causes a compile-time error because install_special_mapping is not defined. This patch adds compile-time guards to the vector mapping functions so that we can build nommu configurations once more.

2011-01-11ARM: sched_clock: make minsec argument to clocks_calc_mult_shift() zeroRussell King
The purpose of the minsec argument is to prevent 64-bit math overflow when the number of cycles is multiplied up. However, the multipler is 32-bit, and in the sched_clock() case, the cycle counter is up to 32-bit as well. So the math can never overflow. With a value of 60, and clock rates greater than 71MHz, the calculated multiplier is unnecessarily reduced in value, which reduces accuracy by maybe 70ppt. It's almost not worth bothering with as the oscillator driving the counter won't be any more than 1ppm - unless you're using a rubidium lamp or caesium fountain frequency standard. So, set the minsec argument to zero. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-01-11ARM: sched_clock: allow init_sched_clock() to be called earlyRussell King
sched_clock is supposed to be initialized early - in the recently added init_early platform hook. However, in doing so we end up calling mod_timer() before the timer lists are initialized, resulting in an oops. Split the initialization in two - the part which the platform calls early which starts things off. The addition of the timer can be delayed until after we have more of the kernel initialized - when the normal time sources are initialized. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2011-01-10ARM: udelay: prevent math rounding resulting in short udelaysRussell King
We perform the microseconds to loops calculation using a number of multiplies and shift rights. Each shift right rounds down the resulting value, which can result in delays shorter than requested. Ensure that we always round up. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2011-01-06cassini: Use local-mac-address prom property for Cassini MAC addressRichard Mortimer
Fallback on the local-mac-address prom property if the Cassini device does not have an address programmed in the VPD ROM. This uses the same technique as implemented by the sungem driver. The problem was reported by Frans van Berckel using Debian kernel 2.6.34-7 on Sun Fire V440. udev was assigning a new eth<n> device name on each reboot because the cassini driver was using a random MAC address. Fix tested on 2.6.34-7 and 2.6.37 Sun Fire V440.

2011-01-06atyfb: Fix bootup hangs on sparc64.David S. Miller
After commit 25edd6946a1d74e5e77813c2324a0908c68bcf9e ("sparc64: Get rid of indirect p1275 PROM call buffer.") we can't pass virtual addresses >4GB to PROM calls. Largely this is never necessary in drivers because we have a copy of the entire PROM device tree in the kernel and a set of of_*() interfaces to access it. Unfortunately there were some lingering prom calls in the atyfb driver, in particular prom_finddevice() was being called with an on-stack address which could be anywhere. This code is actually probing for information we already have, the PROM choosen console output device is stored in of_console_device so all of this nasty code consolidates into a one-line comparison. Next we have some prom_getintdefault() calls which are trivially transformed into the equivalent of_getintprop_default(). Special thanks to Fabio, who figured out exactly where the bootup was hanging. That made this bug trivial to fix. Reported-by: Fabio M.

2011-01-06netfilter: fix export secctx error handlingPablo Neira Ayuso
In 1ae4de0cdf855305765592647025bde55e85e451, the secctx was exported via the /proc/net/netfilter/nf_conntrack and ctnetlink interfaces instead of the secmark. That patch introduced the use of security_secid_to_secctx() which may return a non-zero value on error. In one of my setups, I have NF_CONNTRACK_SECMARK enabled but no security modules. Thus, security_secid_to_secctx() returns a negative value that results in the breakage of the /proc and `conntrack -L' outputs. To fix this, we skip the inclusion of secctx if the aforementioned function fails. This patch also fixes the dynamic netlink message size calculation if security_secid_to_secctx() returns an error, since its logic is also wrong. This problem exists in Linux kernel >= 2.6.37.

RFC3168 (The Addition of Explicit Congestion Notification to IP) states : 5.3. Fragmentation ECN-capable packets MAY have the DF (Don't Fragment) bit set. Reassembly of a fragmented packet MUST NOT lose indications of congestion. In other words, if any fragment of an IP packet to be reassembled has the CE codepoint set, then one of two actions MUST be taken: * Set the CE codepoint on the reassembled packet. However, this MUST NOT occur if any of the other fragments contributing to this reassembly carries the Not-ECT codepoint. * The packet is dropped, instead of being reassembled, for any other reason. This patch implements this requirement for IPv4, choosing the first action : If one fragment had NO-ECT codepoint reassembled frame has NO-ECT ElIf one fragment had CE codepoint reassembled frame has CE Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2011-01-06net: add POLLPRI to sock_def_readable()Eric Dumazet
Leonardo Chiquitto found poll() could block forever on tcp sockets and Urgent data was received, if the event flag only contains POLLPRI. He did a bisection and found commit 4938d7e0233 (poll: avoid extra wakeups in select/poll) was the source of the problem. Problem is TCP sockets use standard sock_def_readable() function for their sk_data_ready() handler, and sock_def_readable() doesnt signal POLLPRI. Only TCP is affected by the problem. Adding POLLPRI to the list of flags might trigger unnecessary schedules, but URGENT handling is such a seldom used feature this seems a good compromise. Thanks a lot to Leonardo for providing the bisection result and a test program as well.
