[ Upstream commit b3d0db7 ] Now that we have open file cache, it is possible that another client deletes the file and DP will not know about it. Then IO to MDS would fail with BADSTATEID and knfsd would start state recovery, which should fail as well and then nfs read/write will fail with EBADF. And it triggers a WARN() in nfserrno(). -----------[ cut here ]------------ WARNING: CPU: 0 PID: 13529 at fs/nfsd/nfsproc.c:758 nfserrno+0x58/0x70 [nfsd]() nfsd: non-standard errno: -9 modules linked in: nfsv3 nfs_layout_flexfiles rpcsec_gss_krb5 nfsv4 dns_resolver nfs fscache ip6t_rpfilter ip6t_REJECT nf_reject_ipv6 xt_connt pata_acpi floppy CPU: 0 PID: 13529 Comm: nfsd Tainted: G W 4.1.5-00307-g6e6579b compulab-yokneam#7 Hardware name: VMware, Inc.

[ Upstream commit 1947b92464c3268381604bbe2ac977a3fd78192f ] Parallel testing appears to show a race between allocating and setting evsel ids. As there is a bounds check on the xyarray it yields a segv like: ``` AddressSanitizer:DEADLYSIGNAL ================================================================= ==484408==ERROR: AddressSanitizer: SEGV on unknown address 0x000000000010 ==484408==The signal is caused by a WRITE memory access. ==484408==Hint: address points to the zero page. #0 0x55cef5d4eff4 in perf_evlist__id_hash tools/lib/perf/evlist.c:256 compulab-yokneam#1 0x55cef5d4f132 in perf_evlist__id_add tools/lib/perf/evlist.c:274 compulab-yokneam#2 0x55cef5d4f545 in perf_evlist__id_add_fd tools/lib/perf/evlist.c:315 compulab-yokneam#3 0x55cef5a1923f in store_evsel_ids util/evsel.c:3130 compulab-yokneam#4 0x55cef5a19400 in evsel__store_ids util/evsel.c:3147 compulab-yokneam#5 0x55cef5888204 in __run_perf_stat tools/perf/builtin-stat.c:832 compulab-yokneam#6 0x55cef5888c06 in run_perf_stat tools/perf/builtin-stat.c:960 compulab-yokneam#7 0x55cef58932db in cmd_stat tools/perf/builtin-stat.c:2878 ... ``` Avoid this crash by early exiting the perf_evlist__id_add_fd and perf_evlist__id_add is the access is out-of-bounds.

[ Upstream commit f8bbc07ac535593139c875ffa19af924b1084540 ] vhost_worker will call tun call backs to receive packets. If too many illegal packets arrives, tun_do_read will keep dumping packet contents. When console is enabled, it will costs much more cpu time to dump packet and soft lockup will be detected. net_ratelimit mechanism can be used to limit the dumping rate.

Hi all, is it possible to add CIFS fileshare by default in the kernel?
I tried to build my own kernel for v3.0 and it worked according to this instruction: https://github.com/compulab-yokneam/Documentation/blob/master/etc/linux_kernel_deployment.md#create-deb-package
But after every reboot the old kernel version is still active.
Is it possible that this section is not correct for my plan?
