When some of group member has 0 overhead, it printed previous percentage instead of 0.00%. It's because passing integer 0 as a percent rather than double 0.0 so the remaining bits came from garbage. The TUI and GTK don't have this problem since they pass 0.0.

Don Zickus authored
Currently if a process creates a bunch of threads using pthread_create and then perf is run in system_wide mode, the mmaps for those threads are not captured with a synthesized mmap event. The reason is those threads are not visible when walking the /proc/ directory looking for /proc/<pid>/maps files. Instead they are discovered using the /proc/<pid>/tasks file (which the synthesized comm event uses). This causes problems when a program is trying to map a data address to a tid. Because the tid has no maps, the event is dropped. Changing the program to look up using the pid instead of the tid, finds the correct maps but creates ugly hacks in the program to carry the correct tid around. Fix this by moving the walking of the /proc/<pid>/tasks up a level (out of the comm function) based on Arnaldo's suggestion. Tweaked things a bit to special case the 'full' bit and 'guest' check.

Introduce futexes to perf-bench and add a program that stresses and measures the kernel's implementation of the hash table. This is a multi-threaded program that simply measures the amount of failed futex wait calls - we only want to deal with the hashing overhead, so a negative return of futex_wait_setup() is enough to do the trick. An example run: $ perf bench futex hash -t 32 Run summary [PID 10989]: 32 threads, each operating on 1024 [private] futexes for 10 secs. [thread 0] futexes: 0x19d9b10 ... 0x19dab0c [ 418713 ops/sec ] [thread 1] futexes: 0x19daca0 ... 0x19dbc9c [ 469913 ops/sec ] [thread 2] futexes: 0x19dbe30 ... 0x19dce2c [ 479744 ops/sec ] ...

Commit: 411cf180 perf/x86/uncore: fix initialization of cpumask introduced the function uncore_cpumask_init(), which is only called in __init intel_uncore_init(). But it is not marked with __init, which produces the following warning: WARNING: vmlinux.o(.text+0x2464a): Section mismatch in reference from the function uncore_cpumask_init() to the function .init.text:uncore_cpu_setup() The function uncore_cpumask_init() references the function __init uncore_cpu_setup(). This is often because uncore_cpumask_init lacks a __init annotation or the annotation of uncore_cpu_setup is wrong. This patch marks uncore_cpumask_init() with __init. Signed-off-by:

Adds support for HFSX 'HasFolderCount' flag and a corresponding 'folderCount' field in folder records. (For reference see HFS_FOLDERCOUNT and kHFSHasFolderCountBit/kHFSHasFolderCountMask in Apple's source code.) Ignoring subfolder count leads to fs errors found by Mac: ... Checking catalog hierarchy. HasFolderCount flag needs to be set (id = 105) (It should be 0x10 instead of 0) Incorrect folder count in a directory (id = 2) (It should be 7 instead of 6) ... Steps to reproduce: Format with "newfs_hfs -s /dev/diskXXX". Mount in Linux. Create a new directory in root. Unmount. Run "fsck_hfs /dev/diskXXX". The patch handles directory creation, deletion, and rename. Signed-off-by:

The expected logic of proc_map_files_get_link() is either to return 0 and initialize 'path' or return an error and leave 'path' uninitialized. By the time dname_to_vma_addr() returns 0 the corresponding vma may have already be gone. In this case the path is not initialized but the return value is still 0. This results in 'general protection fault' inside d_path().

We received several reports of bad page state when freeing CMA pages previously allocated with alloc_contig_range: BUG: Bad page state in process Binder_A pfn:63202 page:d21130b0 count:0 mapcount:1 mapping: (null) index:0x7dfbf page flags: 0x40080068(uptodate|lru|active|swapbacked) Based on the page state, it looks like the page was still in use. The page flags do not make sense for the use case though. Further debugging showed that despite alloc_contig_range returning success, at least one page in the range still remained in the buddy allocator. There is an issue with isolate_freepages_block. In strict mode (which CMA uses), if any pages in the range cannot be isolated, isolate_freepages_block should return failure 0. The current check keeps track of the total number of isolated pages and compares against the size of the range: if (strict && nr_strict_required > total_isolated) total_isolated = 0; After taking the zone lock, if one of the pages in the range is not in the buddy allocator, we continue through the loop and do not increment total_isolated. If in the last iteration of the loop we isolate more than one page (e.g. last page needed is a higher order page), the check for total_isolated may pass and we fail to detect that a page was skipped. The fix is to bail out if the loop immediately if we are in strict mode. There's no benfit to continuing anyway since we need all pages to be isolated. Additionally, drop the error checking based on nr_strict_required and just check the pfn ranges. This matches with what isolate_freepages_range does.

GFP_THISNODE is for callers that implement their own clever fallback to remote nodes. It restricts the allocation to the specified node and does not invoke reclaim, assuming that the caller will take care of it when the fallback fails, e.g. through a subsequent allocation request without GFP_THISNODE set. However, many current GFP_THISNODE users only want the node exclusive aspect of the flag, without actually implementing their own fallback or triggering reclaim if necessary. This results in things like page migration failing prematurely even when there is easily reclaimable memory available, unless kswapd happens to be running already or a concurrent allocation attempt triggers the necessary reclaim. Convert all callsites that don't implement their own fallback strategy to __GFP_THISNODE. This restricts the allocation a single node too, but at the same time allows the allocator to enter the slowpath, wake kswapd, and invoke direct reclaim if necessary, to make the allocation happen when memory is full.

Linus Torvalds authored
Our write() system call has always been atomic in the sense that you get the expected thread-safe contiguous write, but we haven't actually guaranteed that concurrent writes are serialized wrt f_pos accesses, so threads (or processes) that share a file descriptor and use "write()" concurrently would quite likely overwrite each others data. This violates POSIX.1-2008/SUSv4 Section XSI 2.9.7 that says: "2.9.7 Thread Interactions with Regular File Operations All of the following functions shall be atomic with respect to each other in the effects specified in POSIX.1-2008 when they operate on regular files or symbolic links: [...]" and one of the effects is the file position update. This unprotected file position behavior is not new behavior, and nobody has ever cared. Until now. Yongzhi Pan reported unexpected behavior to Michael Kerrisk that was due to this. This resolves the issue with a f_pos-specific lock that is taken by read/write/lseek on file descriptors that may be shared across threads or processes. Reported-by:

When trying to map a bunch of instruction addresses to their respective threads, I kept getting a lot of bogus entries [I forget the exact reason as I patched my code months ago]. Looking through ip__resolve_ams, I noticed the check for if (al.sym) and realized, most times I have an al.map definition but sometimes an al.sym is undefined. In the cases where al.sym is undefined, the loop keeps going even though a valid al.map exists. Modify this check to use the more reliable al.map. This fixed my bogus entries. Signed-off-by:
