[patch 2/4] mm/mmap.c: don't clobber partially overlapping VMA with MAP_FIXED_NOREPLACE

by akpm＠linux-foundation.org

From: Jann Horn <jannh(a)google.com> Subject: mm/mmap.c: don't clobber partially overlapping VMA with MAP_FIXED_NOREPLACE Daniel Micay reports that attempting to use MAP_FIXED_NOREPLACE in an application causes that application to randomly crash. The existing check for handling MAP_FIXED_NOREPLACE looks up the first VMA that either overlaps or follows the requested region, and then bails out if that VMA overlaps *the start* of the requested region. It does not bail out if the VMA only overlaps another part of the requested region. Fix it by checking that the found VMA only starts at or after the end of the requested region, in which case there is no overlap. Test case: user@debian:~$ cat mmap_fixed_simple.c #include <sys/mman.h> #include <errno.h> #include <stdio.h> #include <stdlib.h> #include <unistd.h> #ifndef MAP_FIXED_NOREPLACE #define MAP_FIXED_NOREPLACE 0x100000 #endif int main(void) { char *p; errno = 0; p = mmap((void*)0x10001000, 0x4000, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS|MAP_FIXED_NOREPLACE, -1, 0); printf("p1=%p err=%m\n", p); errno = 0; p = mmap((void*)0x10000000, 0x2000, PROT_READ, MAP_PRIVATE|MAP_ANONYMOUS|MAP_FIXED_NOREPLACE, -1, 0); printf("p2=%p err=%m\n", p); char cmd[100]; sprintf(cmd, "cat /proc/%d/maps", getpid()); system(cmd); return 0; } user@debian:~$ gcc -o mmap_fixed_simple mmap_fixed_simple.c user@debian:~$ ./mmap_fixed_simple p1=0x10001000 err=Success p2=0x10000000 err=Success 10000000-10002000 r--p 00000000 00:00 0 10002000-10005000 ---p 00000000 00:00 0 564a9a06f000-564a9a070000 r-xp 00000000 fe:01 264004 /home/user/mmap_fixed_simple 564a9a26f000-564a9a270000 r--p 00000000 fe:01 264004 /home/user/mmap_fixed_simple 564a9a270000-564a9a271000 rw-p 00001000 fe:01 264004 /home/user/mmap_fixed_simple 564a9a54a000-564a9a56b000 rw-p 00000000 00:00 0 [heap] 7f8eba447000-7f8eba5dc000 r-xp 00000000 fe:01 405885 /lib/x86_64-linux-gnu/libc-2.24.so 7f8eba5dc000-7f8eba7dc000 ---p 00195000 fe:01 405885 /lib/x86_64-linux-gnu/libc-2.24.so 7f8eba7dc000-7f8eba7e0000 r--p 00195000 fe:01 405885 /lib/x86_64-linux-gnu/libc-2.24.so 7f8eba7e0000-7f8eba7e2000 rw-p 00199000 fe:01 405885 /lib/x86_64-linux-gnu/libc-2.24.so 7f8eba7e2000-7f8eba7e6000 rw-p 00000000 00:00 0 7f8eba7e6000-7f8eba809000 r-xp 00000000 fe:01 405876 /lib/x86_64-linux-gnu/ld-2.24.so 7f8eba9e9000-7f8eba9eb000 rw-p 00000000 00:00 0 7f8ebaa06000-7f8ebaa09000 rw-p 00000000 00:00 0 7f8ebaa09000-7f8ebaa0a000 r--p 00023000 fe:01 405876 /lib/x86_64-linux-gnu/ld-2.24.so 7f8ebaa0a000-7f8ebaa0b000 rw-p 00024000 fe:01 405876 /lib/x86_64-linux-gnu/ld-2.24.so 7f8ebaa0b000-7f8ebaa0c000 rw-p 00000000 00:00 0 7ffcc99fa000-7ffcc9a1b000 rw-p 00000000 00:00 0 [stack] 7ffcc9b44000-7ffcc9b47000 r--p 00000000 00:00 0 [vvar] 7ffcc9b47000-7ffcc9b49000 r-xp 00000000 00:00 0 [vdso] ffffffffff600000-ffffffffff601000 r-xp 00000000 00:00 0 [vsyscall] user@debian:~$ uname -a Linux debian 4.19.0-rc6+ #181 SMP Wed Oct 3 23:43:42 CEST 2018 x86_64 GNU/Linux user@debian:~$ As you can see, the first page of the mapping at 0x10001000 was clobbered.

[PATCH v7 0/7] mm: Merge hmm into devm_memremap_pages, mark GPL-only

by Dan Williams

[ apologies for the resend, script error ] Changes since v6 [1]: * Rebase on next-20181008 and fixup conflicts with the xarray conversion and hotplug optimizations * It has soaked on a 0day visible branch for a few days without any reports. [1]: https://lkml.org/lkml/2018/9/13/104 --- Hi Andrew, Jérôme has reviewed the cleanups, thanks Jérôme. We still disagree on the EXPORT_SYMBOL_GPL status of the core HMM implementation, but Logan, Christoph and I continue to support marking all devm_memremap_pages() derivatives EXPORT_SYMBOL_GPL. HMM has been upstream for over a year, with no in-tree users it is clear it was designed first and foremost for out of tree drivers. It takes advantage of a facility Christoph and I spearheaded to support persistent memory. It continues to see expanding use cases with no clear end date when it will stop attracting features / revisions. It is not suitable to export devm_memremap_pages() as a stable 3rd party driver api. devm_memremap_pages() is a facility that can create struct page entries for any arbitrary range and give out-of-tree drivers the ability to subvert core aspects of page management. It, and anything derived from it (e.g. hmm, pcip2p, etc...), is a deep integration point into the core kernel, and an EXPORT_SYMBOL_GPL() interface. Commit 31c5bda3a656 "mm: fix exports that inadvertently make put_page() EXPORT_SYMBOL_GPL" was merged ahead of this series to relieve some of the pressure from innocent consumers of put_page(), but now we need this series to address *producers* of device pages. More details and justification in the changelogs. The 0day infrastructure has reported success across 152 configs and this survives the libnvdimm unit test suite. Aside from the controversial bits the diffstat is compelling at: 7 files changed, 126 insertions(+), 323 deletions(-) Note that the series has some minor collisions with Alex's recent series to improve devm_memremap_pages() scalability [2]. So, whichever you take first the other will need a minor rebase.
