2020-01-17net: systemport: Fixed queue mapping in internal ring mapFlorian Fainelli1-3/+4
We would not be transmitting using the correct SYSTEMPORT transmit queue during ndo_select_queue() which looks up the internal TX ring map because while establishing the mapping we would be off by 4, so for instance, when we populate switch port mappings we would be doing: switch port 0, queue 0 -> ring index #0 switch port 0, queue 1 -> ring index #1 ... switch port 0, queue 3 -> ring index #3 switch port 1, queue 0 -> ring index #8 (4 + 4 * 1) ... instead of using ring index #4. This would cause our ndo_select_queue() to use the fallback queue mechanism which would pick up an incorrect ring for that switch port. Fix this by using the correct switch queue number instead of SYSTEMPORT queue number.

With the implementation of the system reset controller we lost a setting that is currently applied by the bootloader and which configures the IMP port for 2Gb/sec, the default is 1Gb/sec.

2020-01-17net: hns: fix soft lockup when there is not enough memoryYonglong Liu1-3/+1
When there is not enough memory and napi_alloc_skb() return NULL, the HNS driver will print error message, and than try again, if the memory is not enough for a while, huge error message and the retry operation will cause soft lockup. When napi_alloc_skb() return NULL because of no memory, we can get a warn_alloc() call trace, so this patch deletes the error message. We already use polling mode to handle irq, but the retry operation will render the polling weight inactive, this patch just return budget when the rx is not completed to avoid dead loop.

2020-01-17USB: serial: suppress driver bind attributesJohan Hovold1-0/+3
USB-serial drivers must not be unbound from their ports before the corresponding USB driver is unbound from the parent interface so suppress the bind and unbind attributes. Unbinding a serial driver while it's port is open is a sure way to trigger a crash as any driver state is released on unbind while port hangup is handled on the parent USB interface level. Drivers for multiport devices where ports share a resource such as an interrupt endpoint also generally cannot handle individual ports going away.

2020-01-17net: avoid updating qdisc_xmit_lock_key in netdev_update_lockdep_key()Cong Wang1-12/+0
syzbot reported some bogus lockdep warnings, for example bad unlock balance in sch_direct_xmit(). They are due to a race condition between slow path and fast path, that is qdisc_xmit_lock_key gets re-registered in netdev_update_lockdep_key() on slow path, while we could still acquire the queue->_xmit_lock on fast path in this small window: CPU A CPU B __netif_tx_lock(); lockdep_unregister_key(qdisc_xmit_lock_key); __netif_tx_unlock(); lockdep_register_key(qdisc_xmit_lock_key); In fact, unlike the addr_list_lock which has to be reordered when the master/slave device relationship changes, queue->_xmit_lock is only acquired on fast path and only when NETIF_F_LLTX is not set, so there is likely no nested locking for it. Therefore, we can just get rid of re-registration of qdisc_xmit_lock_key.

The commit 91d2a812dfb9 ("locking/rwsem: Make handoff writer optimistically spin on owner") will allow a recently woken up waiting writer to spin on the owner. Unfortunately, if the owner happens to be RWSEM_OWNER_UNKNOWN, the code will incorrectly spin on it leading to a kernel crash. This is fixed by passing the proper non-spinnable bits to rwsem_spin_on_owner() so that RWSEM_OWNER_UNKNOWN will be treated as a non-spinnable target.

2020-01-16netfilter: nat: fix ICMP header corruption on ICMP errorsEyal Birger1-0/+13
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 Szeredi1-1/+3
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().

2020-01-15scsi: mptfusion: Fix double fetch bug in ioctlDan Carpenter1-163/+50
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.

2020-01-15Merge branch 'bpf-sockmap-tls-fixes'Daniel Borkmann9-25/+66
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>
