2019-03-24net: sched: fix cleanup NULL pointer exception in act_mirrJohn Hurley1-2/+5
A new mirred action is created by the tcf_mirred_init function. This contains a list head struct which is inserted into a global list on successful creation of a new action. However, after a creation, it is still possible to error out and call the tcf_idr_release function. This, in turn, calls the act_mirr cleanup function via __tcf_idr_release and __tcf_action_put. This cleanup function tries to delete the list entry which is as yet uninitialised, leading to a NULL pointer exception. Fix this by initialising the list entry on creation of a new action.

2019-03-23ext4: brelse all indirect buffer in ext4_ind_remove_space()zhangyi (F)1-4/+8
All indirect buffers get by ext4_find_shared() should be released no mater the branch should be freed or not. But now, we forget to release the lower depth indirect buffers when removing space from the same higher depth indirect block. It will lead to buffer leak and futher more, it may lead to quota information corruption when using old quota, consider the following case. - Create and mount an empty ext4 filesystem without extent and quota features, - quotacheck and enable the user & group quota, - Create some files and write some data to them, and then punch hole to some files of them, it may trigger the buffer leak problem mentioned above. - Disable quota and run quotacheck again, it will create two new aquota files and write the checked quota information to them, which probably may reuse the freed indirect block(the buffer and page cache was not freed) as data block. - Enable quota again, it will invoke vfs_load_quota_inode()->invalidate_bdev() to try to clean unused buffers and pagecache. Unfortunately, because of the buffer of quota data block is still referenced, quota code cannot read the up to date quota info from the device and lead to quota information corruption. This problem can be reproduced by xfstests generic/231 on ext3 file system or ext4 file system without extent and quota features. This patch fix this problem by releasing the missing indirect buffers, in ext4_ind_remove_space().

2019-03-23x86/gart: Exclude GART aperture from kcoreKairui Song3-7/+42
On machines where the GART aperture is mapped over physical RAM, /proc/kcore contains the GART aperture range. Accessing the GART range via /proc/kcore results in a kernel crash. vmcore used to have the same issue, until it was fixed with commit 2a3e83c6f96c ("x86/gart: Exclude GART aperture from vmcore")', leveraging existing hook infrastructure in vmcore to let /proc/vmcore return zeroes when attempting to read the aperture region, and so it won't read from the actual memory. Apply the same workaround for kcore. First implement the same hook infrastructure for kcore, then reuse the hook functions introduced in the previous vmcore fix. Just with some minor adjustment, rename some functions for more general usage, and simplify the hook infrastructure a bit as there is no module usage yet.

2019-03-23SMB3: Fix SMB3.1.1 guest mounts to SambaSteve French1-1/+4
Workaround problem with Samba responses to SMB3.1.1 null user (guest) mounts. The server doesn't set the expected flag in the session setup response so we have to do a similar check to what is done in smb3_validate_negotiate where we also check if the user is a null user (but not sec=krb5 since username might not be passed in on mount for Kerberos case). Note that the commit below tightened the conditions and forced signing for the SMB2-TreeConnect commands as per MS-SMB2. However, this should only apply to normal user sessions and not for cases where there is no user (even if server forgets to set the flag in the response) since we don't have anything useful to sign with. This is especially important now that the more secure SMB3.1.1 protocol is in the default dialect list. An earlier patch ("cifs: allow guest mounts to work for smb3.11") fixed the guest mounts to Windows.

2019-03-23fix incorrect error code mapping for OBJECTID_NOT_FOUNDSteve French1-1/+2
It was mapped to EIO which can be confusing when user space queries for an object GUID for an object for which the server file system doesn't support (or hasn't saved one). As Amir Goldstein suggested this is similar to ENOATTR (equivalently ENODATA in Linux errno definitions) so changing NT STATUS code mapping for OBJECTID_NOT_FOUND to ENODATA.

2019-03-23cifs: fix that return -EINVAL when do dedupe operationXiaoli Feng1-1/+1
dedupe_file_range operations is combiled into remap_file_range. But it's always skipped for dedupe operations in function cifs_remap_file_range. Example to test: Before this patch: # dd if=/dev/zero of=cifs/file bs=1M count=1 # xfs_io -c "dedupe cifs/file 4k 64k 4k" cifs/file XFS_IOC_FILE_EXTENT_SAME: Invalid argument After this patch: # dd if=/dev/zero of=cifs/file bs=1M count=1 # xfs_io -c "dedupe cifs/file 4k 64k 4k" cifs/file XFS_IOC_FILE_EXTENT_SAME: Operation not supported Influence for xfstests: generic/091 generic/112 generic/127 generic/263 These tests report this error "do_copy_range:: Invalid argument" instead of "FIDEDUPERANGE: Invalid argument". Because there are still two bugs cause these test failed. https://bugzilla.kernel.org/show_bug.cgi?id=202935 https://bugzilla.kernel.org/show_bug.cgi?id=202785 Signed-off-by: Xiaoli Feng <fengxiaoli0714@gmail.com> Signed-off-by: Steve French <stfrench@microsoft.com>

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent Pull perf/core improvements and fixes from Arnaldo: kernel: Stephane Eranian : - Restore mmap record type correctly when handling PERF_RECORD_MMAP2 events, as the same template is used for all the threads interested in mmap events, some may want just PERF_RECORD_MMAP, while some may want the extra info in MMAP2 records. perf probe: Adrian Hunter: - Fix getting the kernel map, because since changes related to x86 PTI entry trampolines handling, there are more than one kernel map. perf script: Andi Kleen: - Support insn output for normal samples, i.e.: perf script -F ip,sym,insn --xed Will fetch the sample IP from the thread address space and feed it to Intel's XED disassembler, producing lines such as: ffffffffa4068804 native_write_msr wrmsr ffffffffa415b95e __hrtimer_next_event_base movq 0x18(%rax), %rdx That match 'perf annotate's output. - Make the --cpu filter apply to PERF_RECORD_COMM/FORK/... events, in addition to PERF_RECORD_SAMPLE. perf report: - Add a new --samples option to save a small random number of samples per hist entry, using a reservoir technique to select a representative number of samples. Then allow browsing the samples using 'perf script' as part of the hist entry context menu. This automatically adds the right filters, so only the thread or CPU of the sample is displayed. Then we use less' search functionality to directly jump to the time stamp of the selected sample. It uses different menus for assembler and source display. Assembler needs xed installed and source needs debuginfo. - Fix the UI browser scripts pop up menu when there are many scripts available. perf report: Andi Kleen: - Add 'time' sort option.

A fix for our handling of CLOCK_MONOTONIC in the 64-bit VDSO. Changing the wall clock across the Y2038 boundary could cause CLOCK_MONOTONIC to jump forward and backward. Our spectre_v2 reporting was a bit confusing due to a bug I introduced. On some systems it was reporting that the count cache was disabled and also that we were flushing the count cache on context switch. Only the former is true, and given that the count cache is disabled it doesn't make any sense to flush it. No one reported it, so presumably the presence of any mitigation is all people check for. Finally a small build fix for zsmalloc on 32-bit.

2019-03-22x86/hw_breakpoints: Make default case in hw_breakpoint_arch_parse() return ↵Nathan Chancellor1-0/+1
an error When building with -Wsometimes-uninitialized, Clang warns: arch/x86/kernel/hw_breakpoint.c:355:2: warning: variable 'align' is used uninitialized whenever switch default is taken [-Wsometimes-uninitialized] The default cannot be reached because arch_build_bp_info() initializes hw->len to one of the specified cases. Nevertheless the warning is valid and returning -EINVAL makes sure that this cannot be broken by future modifications.

2019-03-22r8169: don't read interrupt mask register in interrupt handlerHeiner Kallweit1-2/+4
After the original patch network starts to crash on heavy load. It's not fully clear why this additional register read has such side effects, but removing it fixes the issue. Thanks also to Alex for his contribution and hints.
