2020-01-16netfilter: nat: fix ICMP header corruption on ICMP errorsEyal Birger
Commit 8303b7e8f018 ("netfilter: nat: fix spurious connection timeouts") made nf_nat_icmp_reply_translation() use icmp_manip_pkt() as the l4 manipulation function for the outer packet on ICMP errors. However, icmp_manip_pkt() assumes the packet has an 'id' field which is not correct for all types of ICMP messages. This is not correct for ICMP error packets, and leads to bogus bytes being written the ICMP header, which can be wrongfully regarded as 'length' bytes by RFC 4884 compliant receivers. Fix by assigning the 'id' field only for ICMP messages that have this semantic.

2020-01-16fuse: fix fuse_send_readpages() in the syncronous read caseMiklos Szeredi
Buffered read in fuse normally goes via: -> generic_file_buffered_read() -> fuse_readpages() -> fuse_send_readpages() ->fuse_simple_request() [called since v5.4] In the case of a read request, fuse_simple_request() will return a non-negative bytecount on success or a negative error value. A positive bytecount was taken to be an error and the PG_error flag set on the page. This resulted in generic_file_buffered_read() falling back to ->readpage(), which would repeat the read request and succeed. Because of the repeated read succeeding the bug was not detected with regression tests or other use cases. The FTP module in GVFS however fails the second read due to the non-seekable nature of FTP downloads. Fix by checking and ignoring positive return value from fuse_simple_request().

2020-01-15block: fix an integer overflow in logical block sizeMikulas Patocka
Logical block size has type unsigned short. That means that it can be at most 32768. However, there are architectures that can run with 64k pages (for example arm64) and on these architectures, it may be possible to create block devices with 64k block size. For exmaple (run this on an architecture with 64k pages): Mount will fail with this error because it tries to read the superblock using 2-sector access: device-mapper: writecache: I/O is not aligned, sector 2, size 1024, block size 65536 EXT4-fs (dm-0): unable to read superblock This patch changes the logical block size from unsigned short to unsigned int to avoid the overflow.

2020-01-15io_uring: clear req->result always before issuing a read/write requestBijan Mottahedeh
req->result is cleared when io_issue_sqe() calls io_read/write_pre() routines. Those routines however are not called when the sqe argument is NULL, which is the case when io_issue_sqe() is called from io_wq_submit_work(). io_issue_sqe() may then examine a stale result if a polled request had previously failed with -EAGAIN: if (ctx->flags & IORING_SETUP_IOPOLL) { if (req->result == -EAGAIN) return -EAGAIN; io_iopoll_req_issued(req); } and in turn cause a subsequently completed request to be re-issued in io_wq_submit_work().

2020-01-15scsi: mptfusion: Fix double fetch bug in ioctlDan Carpenter
Tom Hatskevich reported that we look up "iocp" then, in the called functions we do a second copy_from_user() and look it up again. The problem that could cause is: drivers/message/fusion/mptctl.c 674 /* All of these commands require an interrupt or 675 * are unknown/illegal. 676 */ 677 if ((ret = mptctl_syscall_down(iocp, nonblock)) != 0) ^^^^ We take this lock. 678 return ret; 679 680 if (cmd == MPTFWDOWNLOAD) 681 ret = mptctl_fw_download(arg); ^^^ Then the user memory changes and we look up "iocp" again but a different one so now we are holding the incorrect lock and have a race condition. 682 else if (cmd == MPTCOMMAND) 683 ret = mptctl_mpt_command(arg); The security impact of this bug is not as bad as it could have been because these operations are all privileged and root already has enormous destructive power. But it's still worth fixing. This patch passes the "iocp" pointer to the functions to avoid the second lookup. That deletes 100 lines of code from the driver so it's a nice clean up as well.

2020-01-15scsi: storvsc: Correctly set number of hardware queues for IDE diskLong Li
Commit 0ed881027690 ("scsi: storvsc: setup 1:1 mapping between hardware queue and CPU queue") introduced a regression for disks attached to IDE. For these disks the host VSP only offers one VMBUS channel. Setting multiple queues can overload the VMBUS channel and result in performance drop for high queue depth workload on system with large number of CPUs. Fix it by leaving the number of hardware queues to 1 (default value) for IDE disks.

2020-01-15riscv: make sure the cores stay looping in .Lsecondary_parkGreentime Hu
The code in secondary_park is currently placed in the .init section. The kernel reclaims and clears this code when it finishes booting. That causes the cores parked in it to go to somewhere unpredictable, so we move this function out of init to make sure the cores stay looping there. The instruction bgeu a0, t0, .Lsecondary_park may have "a relocation truncated to fit" issue during linking time. It is because that sections are too far to jump. Let's use tail to jump to the .Lsecondary_park.

2020-01-15Merge branch 'bpf-sockmap-tls-fixes'Daniel Borkmann
John Fastabend says: ==================== To date our usage of sockmap/tls has been fairly simple, the BPF programs did only well-defined pop, push, pull and apply/cork operations. Now that we started to push more complex programs into sockmap we uncovered a series of issues addressed here. Further OpenSSL3.0 version should be released soon with kTLS support so its important to get any remaining issues on BPF and kTLS support resolved. Additionally, I have a patch under development to allow sockmap to be enabled/disabled at runtime for Cilium endpoints. This allows us to stress the map insert/delete with kTLS more than previously where Cilium only added the socket to the map when it entered ESTABLISHED state and never touched it from the control path side again relying on the sockets own close() hook to remove it. To test I have a set of test cases in test_sockmap.c that expose these issues. Once we get fixes here merged and in bpf-next I'll submit the tests to bpf-next tree to ensure we don't regress again. Also I've run these patches in the Cilium CI with OpenSSL (master branch) this will run tools such as netperf, ab, wrk2, curl, etc. to get a broad set of testing. I'm aware of two more issues that we are working to resolve in another couple (probably two) patches. First we see an auth tag corruption in kTLS when sending small 1byte chunks under stress. I've not pinned this down yet. But, guessing because its under 1B stress tests it must be some error path being triggered. And second we need to ensure BPF RX programs are not skipped when kTLS ULP is loaded. This breaks some of the sockmap selftests when running with kTLS. I'll send a follow up for this. v2: I dropped a patch that added !0 size check in tls_push_record this originated from a panic I caught awhile ago with a trace in the crypto stack. But I can not reproduce it anymore so will dig into that and send another patch later if needed. Anyways after a bit of thought it would be nicer if tls/crypto/bpf didn't require special case handling for the !0 size. ==================== Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
2020-01-15bpf: Sockmap/tls, fix pop data with SK_DROP return codeJohn Fastabend
When user returns SK_DROP we need to reset the number of copied bytes to indicate to the user the bytes were dropped and not sent. If we don't reset the copied arg sendmsg will return as if those bytes were copied giving the user a positive return value. This works as expected today except in the case where the user also pops bytes. In the pop case the sg.size is reduced but we don't correctly account for this when copied bytes is reset. The popped bytes are not accounted for and we return a small positive value potentially confusing the user. The reason this happens is due to a typo where we do the wrong comparison when accounting for pop bytes. In this fix notice the if/else is not needed and that we have a similar problem if we push data except its not visible to the user because if delta is larger the sg.size we return a negative value so it appears as an error regardless.
