2011-08-09slub: Fix partial count comparison confusionChristoph Lameter
deactivate_slab() has the comparison if more than the minimum number of partial pages are in the partial list wrong. An effect of this may be that empty pages are not freed from deactivate_slab(). The result could be an OOM due to growth of the partial slabs per node. Frees mostly occur from __slab_free which is okay so this would only affect use cases where a lot of switching around of per cpu slabs occur. Switching per cpu slabs occurs with high frequency if debugging options are enabled.

2011-08-09slub: fix check_bytes() for slub debuggingAkinobu Mita
The check_bytes() function is used by slub debugging. It returns a pointer to the first unmatching byte for a character in the given memory area. If the character for matching byte is greater than 0x80, check_bytes() doesn't work. Becuase 64-bit pattern is generated as below. value64 = value | value << 8 | value << 16 | value << 24; value64 = value64 | value64 << 32; The integer promotions are performed and sign-extended as the type of value is u8. The upper 32 bits of value64 is 0xffffffff in the first line, and the second line has no effect. This fixes the 64-bit pattern generation.

2011-08-09ARM: 7007/1: alignment: Prevent ignoring of faults with ARMv6 unaligned ↵Dave Martin
access model Currently, it's possible to set the kernel to ignore alignment faults when changing the alignment fault handling mode at runtime via /proc/sys/alignment, even though this is undesirable on ARMv6 and above, where it can result in infinite spins where an un-fixed- up instruction repeatedly faults. In addition, the kernel clobbers any alignment mode specified on the command-line if running on ARMv6 or above. This patch factors out the necessary safety check into a couple of new helper functions, and checks and modifies the fault handling mode as appropriate on boot and on writes to /proc/cpu/alignment. Prior to ARMv6, the behaviour is unchanged. For ARMv6 and above, the behaviour changes as follows: * Attempting to ignore faults on ARMv6 results in the mode being forced to UM_FIXUP instead. A warning is printed if this happened as a result of a write to /proc/cpu/alignment. The user's UM_WARN bit (if present) is still honoured. * An alignment= argument from the kernel command-line is now honoured, except that the kernel will modify the specified mode as described above. This is allows modes such as UM_SIGNAL and UM_WARN to be active immediately from boot, which is useful for debugging purposes.

The file mm/proc-arm946.S contains a typo and is missing a structure member in __arm946_proc_info. The former prevents compilation and the latter causes problems during boot. It is likely this file was manually copied from a similar file and not tested, then later updates to the *_proc_info structures missed this file. This patch will apply (with offset) with or without the recent macro unification work that has been done in this directory. This was verified against linux-next/stable last week.

2011-08-08autofs4: fix debug printk warning uncovered by cleanupLinus Torvalds

That thing should be some fixed well-defined size (preferably just 'unsigned int' or 'u32') but for unexplained reasons it is randomly either 'unsigned long' or 'unsigned int' depending on the architecture. For now, cast it to 'unsigned long' for printing, the way we do elsewhere. Somebody else can try to explain the typedef mess.

2011-08-08perf tools: do not look at ./config for configurationJonathan Nieder
In addition to /etc/perfconfig and $HOME/.perfconfig, perf looks for configuration in the file ./config, imitating git which looks at $GIT_DIR/config. If ./config is not a perf configuration file, it fails, or worse, treats it as a configuration file and changes behavior in some unexpected way. "config" is not an unusual name for a file to be lying around and perf does not have a private directory dedicated for its own use, so let's just stop looking for configuration in the cwd. Callers needing context-sensitive configuration can use the PERF_CONFIG environment variable.

2011-08-07dp83640: increase receive time stamp buffer sizeRichard Cochran
The dp83640 buffers receive time stamps from special PHY status frames, matching them to received PTP packets in a work queue. Because the timeout for orphaned time stamps is so long and the buffer is so small, the driver can drop time stamps under moderate PTP traffic. This commit fixes the issue by decreasing the timeout to (at least) one timer tick and increasing the buffer size.

2011-08-07gianfar: fix fiper alignment after resetting the timeRichard Cochran
After resetting the time, the PPS signals on the FIPER output channels are incorrectly offset from the clock time, as can be readily verified by a looping back the FIPER to the external time stamp input. Despite its name, setting the "Fiper Realignment Disable" bit seems to fix the problem, at least on the P2020. Also, following the example code from the Freescale BSP, it is not really necessary to disable and re-enable the timer in order to reprogram the FIPER. (The documentation is rather unclear on this point. It seems that writing to the alarm register also disables the FIPER.)

2011-08-07ipv4: use dst with ref during bcast/mcast loopbackJulian Anastasov
Make sure skb dst has reference when moving to another context. Currently, I don't see protocols that can hit it when sending broadcasts/multicasts to loopback using noref dsts, so it is just a precaution.

2011-08-07ipv4: route non-local sources for raw socketJulian Anastasov
The raw sockets can provide source address for routing but their privileges are not considered. We can provide non-local source address, make sure the FLOWI_FLAG_ANYSRC flag is set if socket has privileges for this, i.e. based on hdrincl (IP_HDRINCL) and transparent flags.

2011-08-07netfilter: TCP and raw fix for ip_route_me_harderJulian Anastasov
TCP in some cases uses different global (raw) socket to send RST and ACK. The transparent flag is not set there. Currently, it is a problem for rerouting after the previous change. Fix it by simplifying the checks in ip_route_me_harder and use FLOWI_FLAG_ANYSRC even for sockets. It looks safe because the initial routing allowed this source address to be used and now we just have to make sure the packet is rerouted. As a side effect this also allows rerouting for normal raw sockets that use spoofed source addresses which was not possible even before we eliminated the ip_route_input call.

2011-08-07net: Make userland include of netlink.h more sane.David S. Miller
Currently userland will barf when including linux/netlink.h unless it precisely includes sys/socket.h first. The issue is where the definition of "sa_family_t" comes from. We've been back and forth on how to fix this issue in the past, see: http://thread.gmane.org/gmane.linux.debian.devel.bugs.general/622621 http://thread.gmane.org/gmane.linux.network/143380 Ben Hutchings suggested we take a hint from how we handle the sockaddr_storage type. First we define a "__kernel_sa_family_t" to linux/socket.h that is always defined. Then if __KERNEL__ is defined, we also define "sa_family_t" as equal to "__kernel_sa_family_t". Then in places like linux/netlink.h we use __kernel_sa_family_t in user visible datastructures. Reported-by: Michel Machado <michel@digirati.com.br> Signed-off-by: David S.

2011-08-07ipv4: Fix ip_getsockopt for IP_PKTOPTIONSDaniel Baluta
IP_PKTOPTIONS is broken for 32-bit applications running in COMPAT mode on 64-bit kernels. This happens because msghdr's msg_flags field is always set to zero. When running in COMPAT mode this should be set to MSG_CMSG_COMPAT instead.
