[PATCH] dma-mapping: benchmark: Extract a common header file for map_benchmark definition

by Tian Tao

kernel/dma/map_benchmark.c and selftests/dma/dma_map_benchmark.c have duplicate map_benchmark definitions, which tends to lead to inconsistent changes to map_benchmark on both sides, extract a common header file to avoid this problem.

[PATCH v2 1/2] selftest/vm: Use correct PAGE_SHIFT value for ppc64

by Aneesh Kumar K.V

Keep it simple by using a #define and limiting hugepage size to 2M. This keeps the test simpler instead of dynamically finding the page size and huge page size. Without this tests are broken w.r.t reading /proc/self/pagemap if (pread(pagemap_fd, ent, sizeof(ent), (uintptr_t)ptr >> (PAGE_SHIFT - 3)) != sizeof(ent)) err(2, "read pagemap"); Cc: Shuah Khan <shuah(a)kernel.org> Cc: linux-kselftest(a)vger.kernel.org Signed-off-by: Aneesh Kumar K.V <aneesh.kumar(a)linux.ibm.com> --- tools/testing/selftests/vm/ksm_tests.c | 9 ++++++++- tools/testing/selftests/vm/transhuge-stress.c | 9 ++++++++- 2 files changed, 16 insertions(+), 2 deletions(-) diff --git a/tools/testing/selftests/vm/ksm_tests.c b/tools/testing/selftests/vm/ksm_tests.c index 1436e1a9a3d3..cae72872152b 100644 --- a/tools/testing/selftests/vm/ksm_tests.c +++ b/tools/testing/selftests/vm/ksm_tests.c @@ -22,7 +22,14 @@ #define KSM_MERGE_ACROSS_NODES_DEFAULT true #define MB (1ul << 20) -#define PAGE_SHIFT 12 +#ifdef __powerpc64__ +#define PAGE_SHIFT 16 +#else +#define PAGE_SHIFT 12 +#endif +/* + * On ppc64 this will only work with radix 2M hugepage size + */ #define HPAGE_SHIFT 21 #define PAGE_SIZE (1 << PAGE_SHIFT) diff --git a/tools/testing/selftests/vm/transhuge-stress.c b/tools/testing/selftests/vm/transhuge-stress.c index 5e4c036f6ad3..b1f8d98355c5 100644 --- a/tools/testing/selftests/vm/transhuge-stress.c +++ b/tools/testing/selftests/vm/transhuge-stress.c @@ -16,7 +16,14 @@ #include <string.h> #include <sys/mman.h> -#define PAGE_SHIFT 12 +#ifdef __powerpc64__ +#define PAGE_SHIFT 16 +#else +#define PAGE_SHIFT 12 +#endif +/* + * On ppc64 this will only work with radix 2M hugepage size + */ #define HPAGE_SHIFT 21 #define PAGE_SIZE (1 << PAGE_SHIFT) -- 2.34.1

[PATCH net-next] ipv6: Reject routes configurations that specify dsfield (tos)

by Guillaume Nault

The ->rtm_tos option is normally used to route packets based on both the destination address and the DS field. However it's ignored for IPv6 routes. Setting ->rtm_tos for IPv6 is thus invalid as the route is going to work only on the destination address anyway, so it won't behave as specified. Suggested-by: Toke Høiland-Jørgensen <toke(a)redhat.com> Signed-off-by: Guillaume Nault <gnault(a)redhat.com> --- The same problem exists for ->rtm_scope. I'm working only on ->rtm_tos here because IPv4 recently started to validate this option too (as part of the DSCP/ECN clarification effort). I'll give this patch some soak time, then send another one for rejecting ->rtm_scope in IPv6 routes if nobody complains. net/ipv6/route.c | 6 ++++++ tools/testing/selftests/net/fib_tests.sh | 13 +++++++++++++ 2 files changed, 19 insertions(+) diff --git a/net/ipv6/route.c b/net/ipv6/route.c index f4884cda13b9..dd98a11fbdb6 100644 --- a/net/ipv6/route.c +++ b/net/ipv6/route.c @@ -5009,6 +5009,12 @@ static int rtm_to_fib6_config(struct sk_buff *skb, struct nlmsghdr *nlh, err = -EINVAL; rtm = nlmsg_data(nlh); + if (rtm->rtm_tos) { + NL_SET_ERR_MSG(extack, + "Invalid dsfield (tos): option not available for IPv6"); + goto errout; + } + *cfg = (struct fib6_config){ .fc_table = rtm->rtm_table, .fc_dst_len = rtm->rtm_dst_len, diff --git a/tools/testing/selftests/net/fib_tests.sh b/tools/testing/selftests/net/fib_tests.sh index bb73235976b3..e2690cc42da3 100755 --- a/tools/testing/selftests/net/fib_tests.sh +++ b/tools/testing/selftests/net/fib_tests.sh @@ -988,12 +988,25 @@ ipv6_rt_replace() ipv6_rt_replace_mpath } +ipv6_rt_dsfield() +{ + echo + echo "IPv6 route with dsfield tests" + + run_cmd "$IP -6 route flush 2001:db8:102::/64" + + # IPv6 doesn't support routing based on dsfield + run_cmd "$IP -6 route add 2001:db8:102::/64 dsfield 0x04 via 2001:db8:101::2" + log_test $? 2 "Reject route with dsfield" +} + ipv6_route_test() { route_setup ipv6_rt_add ipv6_rt_replace + ipv6_rt_dsfield route_cleanup } -- 2.21.3
