2012-11-30ring-buffer: Fix race between integrity check and readersSteven Rostedt1-1/+6
The function rb_check_pages() was added to make sure the ring buffer's pages were sane. This check is done when the ring buffer size is modified as well as when the iterator is released (closing the "trace" file), as that was considered a non fast path and a good place to do a sanity check. The problem is that the check does not have any locks around it. If one process were to read the trace file, and another were to read the raw binary file, the check could happen while the reader is reading the file. The issues with this is that the check requires to clear the HEAD page before doing the full check and it restores it afterward. But readers require the HEAD page to exist before it can read the buffer, otherwise it gives a nasty warning and disables the buffer. By adding the reader lock around the check, this keeps the race from happening. Cc: [email protected] # 3.6 Signed-off-by: Steven Rostedt <[email protected]>
2012-11-30ring-buffer: Fix NULL pointer if rb_set_head_page() failsSteven Rostedt1-2/+7
The function rb_set_head_page() searches the list of ring buffer pages for a the page that has the HEAD page flag set. If it does not find it, it will do a WARN_ON(), disable the ring buffer and return NULL, as this should never happen. But if this bug happens to happen, not all callers of this function can handle a NULL pointer being returned from it. That needs to be fixed.

2012-11-19perf: Make perf build for x86 with UAPI disintegration appliedDavid Howells16-58/+78
Make perf build for x86 once the UAPI disintegration patches for that arch have been applied by adding the appropriate -I flags - in the right order - and then converting some #includes that use ../.. notation to find main kernel headerfiles to use <asm/foo.h> and <linux/foo.h> instead. Note that -Iarch/foo/include/uapi is present _before_ -Iarch/foo/include. This makes sure we get the userspace version of the pt_regs struct. Ideally, we wouldn't have the latter -I flag at all, but unfortunately we want asm/svm.h and asm/vmx.h in builtin-kvm.c and these aren't part of the UAPI - at least not for x86. I wonder if the bits outside of the __KERNEL__ guards *should* be transferred there. I note also that perf seems to do its dependency handling manually by listing all the header files it might want to use in LIB_H in the Makefile. Can this be changed to use -MD? Note that to do make this work, we need to export and UAPI disintegrate linux/hw_breakpoint.h, which I think should've been exported previously so that perf can access the bits. We have to do this in the same patch to maintain bisectability. Signed-off-by: David Howells <[email protected]>

2012-11-19tools: Honour the O= flag when tool build called from a higher MakefileDavid Howells2-6/+17
Honour the O= flag that was passed to a higher level Makefile and then passed down as part of a tool build. To make this work, the top-level Makefile passes the original O= flag and subdir=tools to the tools/Makefile, and that in turn passes subdir=$(O)/$(subdir)/foodir when building tool foo in directory $(O)/$(subdir)/foodir (where the intervening slashes aren't added if an element is missing). For example, take perf. This is found in tools/perf/. Assume we're building into directory ~/zebra/, so we pass O=~/zebra to make. Dependening on where we run the build from, we see: make run in dir $(OUTPUT) dir ======================= ================== linux ~/zebra/tools/perf/ linux/tools ~/zebra/perf/ linux/tools/perf ~/zebra/ and if O= is not set, we get: make run in dir $(OUTPUT) dir ======================= ================== linux linux/tools/perf/ linux/tools linux/tools/perf/ linux/tools/perf linux/tools/perf/ The output directories are created by the descend function if they don't already exist.

2012-10-30perf tools: Fix strbuf_addf() when the buffer needs to growNamhyung Kim1-4/+4
This was found during chasing down the header output regression. The strbuf_addf() was checking buffer length with a result of vscnprintf() which cannot be greater than that of strbuf_avail(). Since numa topology and pmu mapping info in header were converted to use strbuf, it sometimes caused uninteresting behaviors with the broken strbuf. Fix it by using vsnprintf() which returns desired output string length regardless of the available buffer size and grow the buffer if needed.

2012-10-30perf, powerpc: Fix hw breakpoints returning -ENOSPCMichael Neuling1-5/+7
I've been trying to get hardware breakpoints with perf to work on POWER7 but I'm getting the following: % perf record -e mem:0x10000000 true Error: sys_perf_event_open() syscall returned with 28 (No space left on device). /bin/dmesg may provide additional information. Fatal: No CONFIG_PERF_EVENTS=y kernel support configured? true: Terminated (FWIW adding -a and it works fine) Debugging it seems that __reserve_bp_slot() is returning ENOSPC because it thinks there are no free breakpoint slots on this CPU. I have a 2 CPUs, so perf userspace is doing two perf_event_open syscalls to add a counter to each CPU [1]. The first syscall succeeds but the second is failing. On this second syscall, fetch_bp_busy_slots() sets slots.pinned to be 1, despite there being no breakpoint on this CPU. This is because the call the task_bp_pinned, checks all CPUs, rather than just the current CPU. POWER7 only has one hardware breakpoint per CPU (ie. HBP_NUM=1), so we return ENOSPC. The following patch fixes this by checking the associated CPU for each breakpoint in task_bp_pinned. I'm not familiar with this code, so it's provided as a reference to the above issue.

Use rcu_read_lock_sched / rcu_read_unlock_sched / synchronize_sched instead of rcu_read_lock / rcu_read_unlock / synchronize_rcu. This is an optimization. The RCU-protected region is very small, so there will be no latency problems if we disable preempt in this region. So we use rcu_read_lock_sched / rcu_read_unlock_sched that translates to preempt_disable / preempt_disable. It is smaller (and supposedly faster) than preemptible rcu_read_lock / rcu_read_unlock.

2012-10-26VFS: don't do protected {sym,hard}links by defaultLinus Torvalds1-2/+2
In commit 800179c9b8a1 ("This adds symlink and hardlink restrictions to the Linux VFS"), the new link protections were enabled by default, in the hope that no actual application would care, despite it being technically against legacy UNIX (and documented POSIX) behavior. However, it does turn out to break some applications. It's rare, and it's unfortunate, but it's unacceptable to break existing systems, so we'll have to default to legacy behavior. In particular, it has broken the way AFD distributes files, see http://www.dwd.de/AFD/ along with some legacy scripts. Distributions can end up setting this at initrd time or in system scripts: if you have security problems due to link attacks during your early boot sequence, you have bigger problems than some kernel sysctl setting. Do: echo 1 > /proc/sys/fs/protected_symlinks echo 1 > /proc/sys/fs/protected_hardlinks to re-enable the link protections. Alternatively, we may at some point introduce a kernel config option that sets these kinds of "more secure but not traditional" behavioural options automatically.
