* x86, amd: Check X86_FEATURE_OSVW bit before accessing OSVW MSRsAndreas Herrmann2010-05-141-5/+7
| | | | | | | | | | | If host CPU is exposed to a guest the OSVW MSRs are not guaranteed to be present and a GP fault occurs. Thus checking the feature flag is essential.

* x86: Fix fake apicid to node mapping for numa emulationDavid Rientjes2010-05-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With NUMA emulation, it's possible for a single cpu to be bound to multiple nodes since more than one may have affinity if allocated on a physical node that is local to the cpu. APIC ids must therefore be mapped to the lowest node ids to maintain generic kernel use of functions such as cpu_to_node() that determine device affinity. For example, if a device has proximity to physical node 1, for instance, and a cpu happens to be mapped to a higher emulated node id 8, the proximity may not be correctly determined by comparison in generic code even though the cpu may be truly local and allocated on physical node 1. When this happens, the true topology of the machine isn't accurately represented in the emulated environment; although this isn't critical to the system's uptime, any generic code that is NUMA aware benefits from the physical topology being accurately represented. This can affect any system that maps multiple APIC ids to a single node and is booted with numa=fake=N where N is greater than the number of physical nodes.

Skipping keyrings that have been reduced to a zero count seems the way to go. To this end, use atomic_inc_not_zero() to increment the usage count and skip the candidate keyring if that returns false. The following script _may_ cause the bug to happen, but there's no guarantee as the window of opportunity is small: #!/bin/sh LOOP=100000 USER=dummy_user /bin/su -c "exit;" $USER || { /usr/sbin/adduser -m $USER; add=1; } for ((i=0; i<LOOP; i++)) do /bin/su -c "echo '$i' > /dev/null" $USER done (( add == 1 )) && /usr/sbin/userdel -r $USER exit Note that the nominated user must not be in use. An alternative way of testing this may be: for ((i=0; i<100000; i++)) do keyctl session foo /bin/true || break done >&/dev/null as that uses a keyring named "foo" rather than relying on the user and user-session named keyrings.

This driver turns out to be a copy of dm9601.c with symbols renamed and my copyright stripped. That aside, it did contain 1 functional change in dm_write_shared_word(), and after checking the datasheet the original value was indeed wrong (read versus write bits). On Michaels HW, this change bumps receive speed from ~30KB/s to ~900KB/s. On other devices the difference is less spectacular, but still significant (~30%).

| * | | ppp_generic: handle non-linear skbs when passing them to pppdSimon Arlott2010-05-031-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Frequently when using PPPoE with an interface MTU greater than 1500, the skb is likely to be non-linear. If the skb needs to be passed to pppd then the skb data must be read correctly. The previous commit fixes an issue with accidentally sending skbs to pppd based on an invalid read of the protocol type. When that error occurred pppd was reading invalid skb data too.

If this happens and (proto >= 0xc000 || proto == PPP_CCPFRAG) then the packet is passed directly to pppd. This occurs frequently when using PPPoE with an interface MTU greater than 1500 because the skb is more likely to be non-linear. The next 2 bytes need to be pulled in ppp_input(). The pull of 2 bytes in ppp_receive_frame() has been removed as it is no longer required. Signed-off-by: Simon Arlott <simon@fire.lp0.eu> Signed-off-by: David S. Miller <davem@davemloft.net>

The problem is in sctp_process_unk_param: if (NULL == *errp) *errp = sctp_make_op_error_space(asoc, chunk, ntohs(chunk->chunk_hdr->length)); if (*errp) { sctp_init_cause(*errp, SCTP_ERROR_UNKNOWN_PARAM, WORD_ROUND(ntohs(param.p->length))); sctp_addto_chunk(*errp, WORD_ROUND(ntohs(param.p->length)), param.v); When we allocate an error chunk, we assume that the worst case scenario requires that we have chunk_hdr->length data allocated, which would be correct nominally, given that we call sctp_addto_chunk for the violating parameter. Unfortunately, we also, in sctp_init_cause insert a sctp_errhdr_t structure into the error chunk, so the worst case situation in which all parameters are in violation requires chunk_hdr->length+(sizeof(sctp_errhdr_t)*param_count) bytes of data. The result of this error is that a deliberately malformed packet sent to a listening host can cause a remote DOS, described in CVE-2010-1173: http://cve.mitre.org/cgi-bin/cvename.cgi?name=2010-1173 I've tested the below fix and confirmed that it fixes the issue. We move to a strategy whereby we allocate a fixed size error chunk and ignore errors we don't have space to report.

Some of them look like they may just be guesses at possible device IDs, but a few are definitely confirmed devices. This adds the nVidia-branded RF receiver and the X10 Lola Wireless Video Sender device (which contains an RF receiver) to the list of devices in ati_remote.

The clickpad flags are in cap[0]:4 and cap[1]:0 bits. When the device is detected, the driver now reports only the left button as the supported buttons so that X11 driver can detect that the device is Clickpad. A Clickpad device gives the button events only as the middle button. The kernel driver morphs to the left button. The real handling of Clickpad is done rather in X driver side.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 5e28d8eb68c12eab9c4a47b42ba993a6420d71d3 since the magic knock does not work for this model of the touchpad and the device stays in PS/2 compatibility mode.
