* perf top: Wait for a minimal set of events before reading first snapshotFrederic Weisbecker2009-06-071-5/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The first snapshot reading often occur before any events have been read in the mapped perfcounter files. Just wait until we have at least one event before starting the snapshot, or the delay before the first set of entries to be displayed may be long in case of low refresh rate. Note: we could also use a semaphore to wait before "print_entries" number of eveents is reached, but again this value is tunable and we can't ensure we will even reach it. Also we could base on a default mimimum set of entries for the first refresh, say 15, but again, the minimal sample is tunable, and we could end up displaying nothing until we have a minimal default set of events, which can take some time in case of high samples filters. Hence this simple solution which partially covers the default case.

* perf annotate: Automatically pick up vmlinux in the local directoryIngo Molnar2009-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | Right now kernel debug info does not get resolved by default, because we dont know where to look for the vmlinux. The -k option can be used for that - but if no option is given, pick up vmlinux files in the current directory - in case a kernel hacker runs profiling from the source directory that the kernel was built in. The real solution would be to embedd the location (and perhaps the date/timestamp) of the vmlinux file in /proc/kallsyms, so that tools can pick it up automatically.

Making the drm_crtc.c code recognize the DPMS property and invoke the connector->dpms function doesn't remove any capability from the driver while reducing code duplication. That just highlighted the problem with the existing DPMS functions which could turn off the connector, but failed to turn off any relevant crtcs. The new drm_helper_connector_dpms function manages all of that, using the drm_helper-specific crtc and encoder dpms functions, automatically computing the appropriate DPMS level for each object in the system. This fixes the current troubles in the i915 driver which left PLLs, pipes and planes running while in DPMS_OFF mode or even while they were unused.

Stracing dd reveals that it first does an mmap2, which makes 1GB worth of zero page mappings. Then it performs a read on those pages from /dev/zero, and finally it performs a write. The machine died during the reads. Looking at the code, it was noticed that /dev/zero's read operation had been changed by 557ed1fa2620dc119adb86b34c614e152a629a80 ("remove ZERO_PAGE") from giving zero page mappings to actually zeroing the page. The zeroing of the pages causes physical pages to be allocated to the process. But, when the process exhausts all the memory that it can, the kernel cannot kill it, as it is still in the kernel mode allocating more memory. Consequently, the kernel eventually crashes. To fix this, I propose that when a fatal signal is pending during /dev/zero read operation, we simply return and let the user process die.

When we execute 'tc filter add', tcf_proto is allocated, initialized by classifier's init(), and chained. After it's chained, tc_ctl_tfilter() calls classifier's change(). When classifier's change() fails, tc_ctl_tfilter() does not free and keeps tcf_proto. In addition, cls_cgroup is initialized in change() not in init(). It accesses unconfigured struct tcf_proto which is chained before change(), then hits Oops.

E1000 by default does two things: 1) Spans rx descriptors for packets that don't fit into 1 skb on recieve 2) Strips the crc from a frame by subtracting 4 bytes from the length prior to doing an skb_put Since the e1000 driver isn't written to support receiving packets that span multiple rx buffers, it checks the End of Packet bit of every frame, and discards it if its not set. This places us in a situation where, if we have a spanning packet, the first part is discarded, but the second part is not (since it is the end of packet, and it passes the EOP bit test). If the second part of the frame is small (4 bytes or less), we subtract 4 from it to remove its crc, underflow the length, and wind up in skb_over_panic, when we try to skb_put a huge number of bytes into the skb. This amounts to a remote DOS attack through careful selection of frame size in relation to interface MTU. The fix for this is already in the e1000e driver, as well as the e1000 sourceforge driver, but no one ever pushed it to e1000. This is lifted straight from e1000e, and prevents small frames from causing the underflow described above Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Tested-by: Andy Gospodarek <andy@greyhouse.net> Signed-off-by: David S.

Leaving the phy powered on is the safest default behavior. Users accustomed to seeing the link state reflect the interface state and/or wanting to minimize power consumption can set phy_power_down=1 if compatibility with other OSes is not an issue.

That resulted in xfs_fsr deadlocking itself on platforms, which don't handle double unlock of rw_semaphore nicely. It caused the count go negative, which represents the write holder, without really having one. ia64 is one of the platforms where deadlock was easily reproduced and the fix was tested.

Even though it would be better to explicitly have to sg entries for this, we need to support it for the existing users, in particular, IPsec. The new ahash sg walking code did try to handle this, but there was a bug where we didn't increment the page so kept on walking on the first page over an dover again. This patch fixes it.
