2010-07-22ACPI: create "processor.bm_check_disable" boot paramLen Brown
processor.bm_check_disable=1" prevents Linux from checking BM_STS before entering C3-type cpu power states. This may be useful for a system running acpi_idle where the BIOS exports FADT C-states, _CST IO C-states, or _CST FFH C-states with the BM_STS bit set; while configuring the chipset to set BM_STS more frequently than perhaps is optimal. Note that such systems may have been developed using a tickful OS that would quickly clear BM_STS, rather than a tickless OS that may go for some time between checking and clearing BM_STS. Note also that an alternative for newer systems is to use the intel_idle driver, which always ignores BM_STS, relying Linux device drivers to register constraints explicitly via PM_QOS. https://bugzilla.kernel.org/show_bug.cgi?id=15886 Signed-off-by: Len Brown <len.brown@intel.com>
2010-07-22ACPI: skip checking BM_STS if the BIOS doesn't ask for itLen Brown
It turns out that there is a bit in the _CST for Intel FFH C3 that tells the OS if we should be checking BM_STS or not. Linux has been unconditionally checking BM_STS. If the chip-set is configured to enable BM_STS, it can retard or completely prevent entry into deep C-states -- as illustrated by turbostat: http://userweb.kernel.org/~lenb/acpi/utils/pmtools/turbostat/ ref: Intel Processor Vendor-Specific ACPI Interface Specification table 4 "_CST FFH GAS Field Encoding" Bit 1: Set to 1 if OSPM should use Bus Master avoidance for this C-state https://bugzilla.kernel.org/show_bug.cgi?id=15886 Signed-off-by: Len Brown <len.brown@intel.com>

2010-07-22net: Fix corruption of skb csum field in pskb_expand_head() of net/core/skbuff.cAndrea Shepard
Make pskb_expand_head() check ip_summed to make sure csum_start is really csum_start and not csum before adjusting it. This fixes a bug I encountered using a Sun Quad-Fast Ethernet card and VLANs. On my configuration, the sunhme driver produces skbs with differing amounts of headroom on receive depending on the packet size. See line 2030 of drivers/net/sunhme.c; packets smaller than RX_COPY_THRESHOLD have 52 bytes of headroom but packets larger than that cutoff have only 20 bytes. When these packets reach the VLAN driver, vlan_check_reorder_header() calls skb_cow(), which, if the packet has less than NET_SKB_PAD (== 32) bytes of headroom, uses pskb_expand_head() to make more. Then, pskb_expand_head() needs to adjust a lot of offsets into the skb, including csum_start. Since csum_start is a union with csum, if the packet has a valid csum value this will corrupt it, which was the effect I observed. The sunhme hardware computes receive checksums, so the skbs would be created by the driver with ip_summed == CHECKSUM_COMPLETE and a valid csum field, and then pskb_expand_head() would corrupt the csum field, leading to an "hw csum error" message later on, for example in icmp_rcv() for pings larger than the sunhme RX_COPY_THRESHOLD. On the basis of the comment at the beginning of include/linux/skbuff.h, I believe that the csum_start skb field is only meaningful if ip_csummed is CSUM_PARTIAL, so this patch makes pskb_expand_head() adjust it only in that case to avoid corrupting a valid csum value.

2010-07-22macvtap: Limit packet queue lengthHerbert Xu
Mark Wagner reported OOM symptoms when sending UDP traffic over a macvtap link to a kvm receiver. This appears to be caused by the fact that macvtap packet queues are unlimited in length. This means that if the receiver can't keep up with the rate of flow, then we will hit OOM. Of course it gets worse if the OOM killer then decides to kill the receiver. This patch imposes a cap on the packet queue length, in the same way as the tuntap driver, using the device TX queue length. Please note that macvtap currently has no way of giving congestion notification, that means the software device TX queue cannot be used and packets will always be dropped once the macvtap driver queue fills up. This shouldn't be a great problem for the scenario where macvtap is used to feed a kvm receiver, as the traffic is most likely external in origin so congestion notification can't be applied anyway. Of course, if anybody decides to complain about guest-to-guest UDP packet loss down the track, then we may have to revisit this. Incidentally, this patch also fixes a real memory leak when macvtap_get_queue fails. Chris Wright noticed that for this patch to work, we need a non-zero TX queue length. This patch includes his work to change the default macvtap TX queue length to 500.

2010-07-22perf annotate: Fix handling of goto labels that are valid hex numbersArnaldo Carvalho de Melo
When parsing the objdump disassembly output we can have goto labels that are valid hex numbers and thus get confused with lines with machine code. Handle the common case of a label that has nothing after it and other cases where there is just source code by validating the resulting "ip". It is still possible that we find goto labels that are in the function address range, but only if they are located before the real address we should be OK. A change in the objdump output to have a clear marker separating addresses from the disassembly would come handy, but we would still have to deal with older versions.

2010-07-22CIFS: Fix a malicious redirect problem in the DNS lookup codeDavid Howells
Fix the security problem in the CIFS filesystem DNS lookup code in which a malicious redirect could be installed by a random user by simply adding a result record into one of their keyrings with add_key() and then invoking a CIFS CFS lookup [CVE-2010-2524]. This is done by creating an internal keyring specifically for the caching of DNS lookups. To enforce the use of this keyring, the module init routine creates a set of override credentials with the keyring installed as the thread keyring and instructs request_key() to only install lookup result keys in that keyring. The override is then applied around the call to request_key(). This has some additional benefits when a kernel service uses this module to request a key: (1) The result keys are owned by root, not the user that caused the lookup. (2) The result keys don't pop up in the user's keyrings. (3) The result keys don't come out of the quota of the user that caused the lookup. The keyring can be viewed as root by doing cat /proc/keys: 2a0ca6c3 I----- 1 perm 1f030000 0 0 keyring .dns_resolver: 1/4 It can then be listed with 'keyctl list' by root. # keyctl list 0x2a0ca6c3 1 key in keyring: 726766307: --alswrv 0 0 dns_resolver: foo.bar.com Signed-off-by: David Howells <dhowells@redhat.com> Reviewed-and-Tested-by: Jeff Layton <jlayton@redhat.com> Acked-by: Steve French <smfrench@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2010-07-21x86: auditsyscall: fix fastpath return value after rescheduleRoland McGrath
In the CONFIG_AUDITSYSCALL fast-path for x86 64-bit system calls, we can pass a bad return value and/or error indication for the system call to audit_syscall_exit(). This happens when TIF_NEED_RESCHED was set as the system call returned, so we went out to schedule() and came back to the exit-audit fast-path. The fix is to reload the user return value register from the pt_regs before using it for audit_syscall_exit(). Both the 32-bit kernel's fast path and the 64-bit kernel's 32-bit system call fast paths work slightly differently, so that they always leave the fast path entirely to reschedule and don't return there, so they don't have the analogous bugs.

2010-07-20Input: twl40300-keypad - fix handling of "all ground" rowsDmitry Torokhov
The Nokia RX51 board code (arch/arm/mach-omap2/board-rx51-peripherals.c) defines a key map for the matrix keypad keyboard. The hardware seems to use all of the 8 rows and 8 columns of the keypad, although not all possible locations are used. The TWL4030 supports keypads with at most 8 rows and 8 columns. Most keys are defined with a row and column number between 0 and 7, except KEY(0xff, 2, KEY_F9), KEY(0xff, 4, KEY_F10), KEY(0xff, 5, KEY_F11), which represent keycodes that should be emitted when entire row is connected to the ground. since the driver handles this case as if we had an extra column in the key matrix. Unfortunately we do not allocate enough space and end up owerwriting some random memory.
