from int to bool for boolean uses in kernel sources?

by Louis Langholtz

Hi Huang (and others on the lkp mailing list), Might you (or anyone else with a test lab) possibly be interested in testing my github 'bool' branch of the linux kernel sources (https://github.com/louis-langholtz/linux/tree/bool) with your test environment? It might prove interesting to Linux kernel development community. Like many, I prefer using the C-language 'bool' type ('_Bool') over the 'int' type for variables used as boolean. Denoted as bool, I get the idea that the variable is to be used - not surprisingly - in a boolean way that's arguably more encapsulated than an int. I realize though that historically the use of bool within the kernel sources hasn't been without drawbacks and its detractors (https://lkml.org/lkml/2013/8/31/138) too however. The negatives to using bool seem to be really entirely based on the C-language standard used and to the compiler's ability to make use of the bool type on the given hardware. Seems like some clever optimizations should be able to make bool faster than int without breaking things. I've been working in that branch to change code over to use the C-language 'bool' type instead of the 'int' type for variables that are used as booleans. I have so far avoided changing exported symbols but have changed many (if not most) of the internally used boolean variables particularly in the kernel directory. I haven't touched any driver code yet and have tried to stay away from changing arch dependent code. I'm sure I've missed a lot of places as I've just done these refactorings by hand using the Eclipse IDE. I'd like to know what performance changes that has beyond just noticing that the output of the 'size' command shows a space savings when using bool (which is not surprising since the size of a bool using gcc on my VM is 1 while the size of an int is 4). My test resources are much more limited than yours appear to be however. Here's the size output for the linux kernel code to compare with my bool branch (after I compiled the kernel using gcc version 4.8.2 for x86_64): size linux/vmlinux linux-bool/vmlinux text data bss dec hex filename 12009812 1550520 1077248 14637580 df5a0c linux/vmlinux 12009263 1550520 1077248 14637031 df57e7 linux-bool/vmlinux Thank you.

[mm] WARNING: CPU: 1 PID: 681 at mm/mmap.c:2858 exit_mmap()

by Fengguang Wu

Greetings, 0day kernel testing robot got the below dmesg and the first bad commit is git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master commit f7a7b53a90f7a489c4e435d1300db121f6b42776 Author: Kirill A. Shutemov <kirill.shutemov(a)linux.intel.com> AuthorDate: Fri Jan 23 10:11:34 2015 +1100 Commit: Stephen Rothwell <sfr(a)canb.auug.org.au> CommitDate: Fri Jan 23 10:11:34 2015 +1100 mm: account pmd page tables to the process Dave noticed that unprivileged process can allocate significant amount of memory -- >500 MiB on x86_64 -- and stay unnoticed by oom-killer and memory cgroup. The trick is to allocate a lot of PMD page tables. Linux kernel doesn't account PMD tables to the process, only PTE. The use-cases below use few tricks to allocate a lot of PMD page tables while keeping VmRSS and VmPTE low. oom_score for the process will be 0. #include <errno.h> #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <sys/mman.h> #include <sys/prctl.h> #define PUD_SIZE (1UL << 30) #define PMD_SIZE (1UL << 21) #define NR_PUD 130000 int main(void) { char *addr = NULL; unsigned long i; prctl(PR_SET_THP_DISABLE); for (i = 0; i < NR_PUD ; i++) { addr = mmap(addr + PUD_SIZE, PUD_SIZE, PROT_WRITE|PROT_READ, MAP_ANONYMOUS|MAP_PRIVATE, -1, 0); if (addr == MAP_FAILED) { perror("mmap"); break; } *addr = 'x'; munmap(addr, PMD_SIZE); mmap(addr, PMD_SIZE, PROT_WRITE|PROT_READ, MAP_ANONYMOUS|MAP_PRIVATE|MAP_FIXED, -1, 0); if (addr == MAP_FAILED) perror("re-mmap"), exit(1); } printf("PID %d consumed %lu KiB in PMD page tables\n", getpid(), i * 4096 >> 10); return pause(); } The patch addresses the issue by account PMD tables to the process the same way we account PTE. The main place where PMD tables is accounted is __pmd_alloc() and free_pmd_range(). But there're few corner cases: - HugeTLB can share PMD page tables. The patch handles by accounting the table to all processes who share it. - x86 PAE pre-allocates few PMD tables on fork. - Architectures with FIRST_USER_ADDRESS > 0. We need to adjust sanity check on exit(2). Accounting only happens on configuration where PMD page table's level is present (PMD is not folded). As with nr_ptes we use per-mm counter. The counter value is used to calculate baseline for badness score by oom-killer. Signed-off-by: Kirill A.
