2011-05-24net: convert %p usage to %pKDan Rosenberg
The %pK format specifier is designed to hide exposed kernel pointers, specifically via /proc interfaces. Exposing these pointers provides an easy target for kernel write vulnerabilities, since they reveal the locations of writable structures containing easily triggerable function pointers. The behavior of %pK depends on the kptr_restrict sysctl. If kptr_restrict is set to 0, no deviation from the standard %p behavior occurs. If kptr_restrict is set to 1, the default, if the current user (intended to be a reader via seq_printf(), etc.) does not have CAP_SYSLOG (currently in the LSM tree), kernel pointers using %pK are printed as 0's. If kptr_restrict is set to 2, kernel pointers using %pK are printed as 0's regardless of privileges. Replacing with 0's was chosen over the default "(null)", which cannot be parsed by userland %p, which expects "(nil)". The supporting code for kptr_restrict and %pK are currently in the -mm tree. This patch converts users of %p in net/ to %pK. Cases of printing pointers to the syslog are not covered, since this would eliminate useful information for postmortem debugging and the reading of the syslog is already optionally protected by the dmesg_restrict sysctl.

2011-05-23sch_sfq: avoid giving spurious NET_XMIT_CN signalsEric Dumazet
While chasing a possible net_sched bug, I found that IP fragments have litle chance to pass a congestioned SFQ qdisc : - Say SFQ qdisc is full because one flow is non responsive. - ip_fragment() wants to send two fragments belonging to an idle flow. - sfq_enqueue() queues first packet, but see queue limit reached : - sfq_enqueue() drops one packet from 'big consumer', and returns NET_XMIT_CN. - ip_fragment() cancel remaining fragments. This patch restores fairness, making sure we return NET_XMIT_CN only if we dropped a packet from the same flow.

2011-05-23ehea: Fix multicast registration on semi-promiscuous modeBreno Leitao
Ehea will not register multicast groups in phyp if the physical interface is in promiscuous mode. But it should register if the logical port is in promiscuous mode, but the physical port is not. Ehea physical promiscuous mode is defined by ehea_port->promisc, while logical port is defined by IFF_PROMISC. So currently, if the user set the interface in promiscuous mode, IGMP will not be registred in PHYP, and PHYP will never pass the multicast packet to the logical port, which is bad So, this patch just fixes it, assuring that we register in phyp if the physical port is not on promiscuous mode.

Commit eac9eacee16 "perf tools: Check we are able to read the event size on mmap" brought a check to ensure we can read the size of the event before dereferencing it, and do a remap otherwise to move the buffer forward. However that remap was ommitting all the necessary work to update the new page offset, head, and to unmap previous pages, etc... To fix this, gather all the code that fetches the event in a seperate helper which does all the necessary checks about the header/event size and tells us anytime a remap is needed.

2011-05-23apm-emulation: apm_mutex breaks ACK; remove itPaul Parsons
apm_mutex is locked by a process (e.g. apm -s) at the start of apm_ioctl() and remains locked while pm_suspend() is called. Any subsequent process trying to ACK the suspend (e.g. apmd) is then blocked at the start of apm_ioctl(), causing the suspend to be delayed for 5 seconds in apm_suspend_notifier() while the ACK times out. In short, ACKs don't work. The driver's data structures are sufficiently protected by assorted locks. And pm_suspend() has its own mutex to prevent reentrancy. Consequently there is no obvious requirement for apm_mutex, which evolved from earlier BKL calls. So let's remove it. Signed-off-by: Paul Parsons <lost.distance@yahoo.com> Acked-by: Rafael J.

2011-05-23watchdog: Change the default timeout and configure nmi watchdog period based ↵Mandeep Singh Baines
on watchdog_thresh Before the conversion of the NMI watchdog to perf event, the watchdog timeout was 5 seconds. Now it is 60 seconds. For my particular application, netbooks, 5 seconds was a better timeout. With a short timeout, we catch faults earlier and are able to send back a panic. With a 60 second timeout, the user is unlikely to wait and will instead hit the power button, causing us to lose the panic info. This change configures the NMI period to watchdog_thresh and sets the softlockup_thresh to watchdog_thresh * 2. In addition, watchdog_thresh was reduced to 10 seconds as suggested by Ingo Molnar.

2011-05-22x86: setup_smep needs to be __cpuinitLinus Torvalds
The setup_smep function gets calle at resume time too, and is thus not a pure __init function. When marked as __init, it gets thrown out after the kernel has initialized, and when the kernel is suspended and resumed, the code will no longer be around, and we'll get a nice "kernel tried to execute NX-protected page" oops because the page is no longer marked executable.

2011-05-22Remove prefetch() from <linux/skbuff.h> and "netlabel_addrlist.h"Linus Torvalds
Commit e66eed651fd1 ("list: remove prefetching from regular list iterators") removed the include of prefetch.h from list.h. The skbuff list traversal still had them. Quoth David Miller: "Please just remove the prefetches. Those are modelled after list.h as I intend to eventually convert SKB list handling to "struct list_head" but we're not there yet. Therefore if we kill prefetches from list.h we should kill it from these things in skbuff.h too."

2011-05-22Add appropriate <linux/prefetch.h> include for prefetch usersPaul Gortmaker
After discovering that wide use of prefetch on modern CPUs could be a net loss instead of a win, net drivers which were relying on the implicit inclusion of prefetch.h via the list headers showed up in the resulting cleanup fallout. Give them an explicit include via the following $0.02 script. ========================================= #!/bin/bash MANUAL="" for i in `git grep -l 'prefetch(.*)' .` ; do grep -q '<linux/prefetch.h>' $i if [ $? = 0 ] ; then continue fi ( echo '?^#include <linux/?a' echo '#include <linux/prefetch.h>' echo . echo w echo q ) | ed -s $i > /dev/null 2>&1 if [ $? != 0 ]; then echo $i needs manual fixup MANUAL="$i $MANUAL" fi done echo ------------------- 8\<---------------------- echo vi $MANUAL ========================================= Signed-off-by: Paul <paul.gortmaker@windriver.com> [ Fixed up some incorrect #include placements, and added some non-network drivers and the fib_trie.c case - Linus ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
