2011-03-21matroxfb: remove incorrect Matrox G200eV supportGary Hade1-9/+0
Remove incorrect Matrox G200eV support that was previously added by commit e3a1938805d2e81b27d3d348788644f3bad004f2 A serious issue with the incorrect G200eV support that reproduces on the Matrox G200eV equipped IBM x3650 M2 is the total lack of text (login banner, login prompt, etc) on the console when X is not running and total lack of text on all of the virtual consoles after X is started. Any concerns that the incorrect code (upstream since October 2008) has been successfully used on non-IBM G200eV equipped system(s) appear to be unwarranted. In addition to the serious/non-intermittent nature of issues that have been spotted on IBM systems, complete removal of the incorrect code is clearly supported by the following Matrox (Yannick Heneault) provided input: "It impossible that this patch should have work on a system. The patch only declare the G200eV as a regular G200 which is not case. Many registers are different, including at least the PLL programming sequence. If the G200eV is programmed like a regular G200, it will not display anything." v1 - Initial patch that removed the incorrect code for _all_ G200eV equipped systems. v2 - Darrick Wong provided patch that blacklisted the incorrect code on G200eV equipped IBM systems leaving it enabled on all G200eV equipped non-IBM systems. v3 - Same code changes included with v1 plus additional justification for complete removal of the incorrect code.

2011-03-21Prevent rt_sigqueueinfo and rt_tgsigqueueinfo from spoofing the signal codeJulien Tinnes1-4/+12
Userland should be able to trust the pid and uid of the sender of a signal if the si_code is SI_TKILL. Unfortunately, the kernel has historically allowed sigqueueinfo() to send any si_code at all (as long as it was negative - to distinguish it from kernel-generated signals like SIGILL etc), so it could spoof a SI_TKILL with incorrect siginfo values. Happily, it looks like glibc has always set si_code to the appropriate SI_QUEUE, so there are probably no actual user code that ever uses anything but the appropriate SI_QUEUE flag. So just tighten the check for si_code (we used to allow any negative value), and add a (one-time) warning in case there are binaries out there that might depend on using other si_code values.

2011-03-21libceph: fix osd request queuing on osdmap updatesSage Weil2-135/+125
If we send a request to osd A, and the request's pg remaps to osd B and then back to A in quick succession, we need to resend the request to A. The old code was only calling kick_requests after processing all incremental maps in a message, so it was very possible to not resend a request that needed to be resent. This would make the osd eventually time out (at least with the current default of osd timeouts enabled). The correct approach is to scan requests on every map incremental. This patch refactors the kick code in a few ways: - all requests are either on req_lru (in flight), req_unsent (ready to send), or req_notarget (currently map to no up osd) - mapping always done by map_request (previous map_osds) - if the mapping changes, we requeue. requests are resent only after all map incrementals are processed. - some osd reset code is moved out of kick_requests into a separate function - the "kick this osd" functionality is moved to kick_osd_requests, as it is unrelated to scanning for request->pg->osd mapping changes Signed-off-by: Sage Weil <[email protected]>

Make the LM75/LM75A device detection faster: * Don't read the current temperature value when we don't use it. * Check for unused bits in the configuration register as soon as we have read its value. * Don't use word reads, not all devices support this, and some which don't misbehave when you try. * Check for cycling register values every 40 register addresses instead of every 8, it's 5 times faster and just as efficient. Some of these improvements come straight from the user-space sensors-detect script, so both detection routines are in line now.

2011-03-21bfs: fix bitmap size argument to find_first_zero_bit()Akinobu Mita1-1/+1
The usage of find_first_zero_bit() in bfs_create() is wrong for two reasons. The bitmap size argument to find_first_zero_bit() is info->si_lasti but the correct bitmap size is info->si_lasti + 1 as info->si_lasti is the last valid index in info->si_imap bitmap. Another problem is that it is impossible to detect that info->si_imap bitmap is full because there is an off-by-one bug in the return value check for find_first_zero_bit(). If no zero bits exist in info->si_imap, find_first_zero_bit() returns info->si_lasti. But the check can't catch it due to the off-by-one.
