commit 98375b86 upstream. The syzbot fuzzer provoked a general protection fault in the hid-prodikeys driver: kasan: CONFIG_KASAN_INLINE enabled kasan: GPF could be caused by NULL-ptr deref or user memory access general protection fault: 0000 [#1] SMP KASAN CPU: 0 PID: 12 Comm: kworker/0:1 Not tainted 5.3.0-rc5+ #28 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/01/2011 Workqueue: usb_hub_wq hub_event RIP: 0010:pcmidi_submit_output_report drivers/hid/hid-prodikeys.c:300 [inline] RIP: 0010:pcmidi_set_operational drivers/hid/hid-prodikeys.c:558 [inline] RIP: 0010:pcmidi_snd_initialise drivers/hid/hid-prodikeys.c:686 [inline] RIP: 0010:pk_probe+0xb51/0xfd0 drivers/hid/hid-prodikeys.c:836 Code: 0f 85 50 04 00 00 48 8b 04 24 4c 89 7d 10 48 8b 58 08 e8 b2 53 e4 fc 48 8b 54 24 20 48 b8 00 00 00 00 00 fc ff df 48 c1 ea 03 <80> 3c 02 00 0f 85 13 04 00 00 48 ba 00 00 00 00 00 fc ff df 49 8b The problem is caused by the fact that pcmidi_get_output_report() will return an error if the HID device doesn't provide the right sort of output report, but pcmidi_set_operational() doesn't bother to check the return code and assumes the function call always succeeds. This patch adds the missing check and aborts the probe operation if necessary. Reported-and-tested-by: syzbot+1088533649dafa1c9004@syzkaller.appspotmail.com Signed-off-by:

commit f794809a upstream. The upstream kernel commit cited below modified the workqueue in the new CQ API to be bound to a specific CPU (instead of being unbound). This caused ALL users of the new CQ API to use the same bound WQ. Specifically, MAD handling was severely delayed when the CPU bound to the WQ was busy handling (higher priority) interrupts. This caused a delay in the MAD "heartbeat" response handling, which resulted in ports being incorrectly classified as "down". To fix this, add a new "unbound" WQ type to the new CQ API, so that users have the option to choose either a bound WQ or an unbound WQ. For MADs, choose the new "unbound" WQ.

[ Upstream commit 6efb971b ] When tcf_block_get() fails in sfb_init(), q->qdisc is still a NULL pointer which leads to a crash in sfb_destroy(). Similar for sch_dsmark. Instead of fixing each separately, Linus suggested to just accept NULL pointer in qdisc_put(), which would make callers easier. (For sch_dsmark, the bug probably exists long before commit 6529eaba.)

This is a custom patch (no mainline equivalent) for stable backport only to address 0-Day kernel test infra ARC 4.x.y builds errors. The reason for this custom patch as that it is a single patch, touches only ARC, vs. atleast two 7c2c11b2, dc8635b7 which touch atleast 3 other arches (one long removed) and could potentially have a fallout.

[ Upstream commit 754265bc ] After the conversion to lock-less dma-api call the increase_address_space() function can be called without any locking. Multiple CPUs could potentially race for increasing the address space, leading to invalid domain->mode settings and invalid page-tables. This has been happening in the wild under high IO load and memory pressure. Fix the race by locking this operation. The function is called infrequently so that this does not introduce a performance regression in the dma-api path again. Reported-by:

[ Upstream commit 0f4cd769 ] When counting dispatched micro-ops with cnt_ctl=1, in order to prevent sample bias, IBS hardware preloads the least significant 7 bits of current count (IbsOpCurCnt) with random values, such that, after the interrupt is handled and counting resumes, the next sample taken will be slightly perturbed. The current count bitfield is in the IBS execution control h/w register, alongside the maximum count field. Currently, the IBS driver writes that register with the maximum count, leaving zeroes to fill the current count field, thereby overwriting the random bits the hardware preloaded for itself. Fix the driver to actually retain and carry those random bits from the read of the IBS control register, through to its write, instead of overwriting the lower current count bits with zeroes. Tested with: perf record -c 100001 -e ibs_op/cnt_ctl=1/pp -a -C 0 taskset -c 0 <workload> 'perf annotate' output before: 15.70 65: addsd %xmm0,%xmm1 17.30 add $0x1,%rax 15.88 cmp %rdx,%rax je 82 17.32 72: test $0x1,%al jne 7c 7.52 movapd %xmm1,%xmm0 5.90 jmp 65 8.23 7c: sqrtsd %xmm1,%xmm0 12.15 jmp 65 'perf annotate' output after: 16.63 65: addsd %xmm0,%xmm1 16.82 add $0x1,%rax 16.81 cmp %rdx,%rax je 82 16.69 72: test $0x1,%al jne 7c 8.30 movapd %xmm1,%xmm0 8.13 jmp 65 8.24 7c: sqrtsd %xmm1,%xmm0 8.39 jmp 65 Tested on Family 15h and 17h machines. Machines prior to family 10h Rev. C don't have the RDWROPCNT capability, and have the IbsOpCurCnt bitfield reserved, so this patch shouldn't affect their operation. It is unknown why commit db98c5fa ("perf/x86: Implement 64-bit counter support for IBS") ignored the lower 4 bits of the IbsOpCurCnt field; the number of preloaded random bits has always been 7, AFAICT.

[ Upstream commit f53a7ad1 ] get_registers() blindly copies the memory written to by the usb_control_msg() call even if the underlying urb failed. This could lead to junk register values being read by the driver, since some indirect callers of get_registers() ignore the return values. One example is: ocp_read_dword() ignores the return value of generic_ocp_read(), which calls get_registers(). So, emulate PCI "Master Abort" behavior by setting the buffer to all 0xFFs when usb_control_msg() fails. This patch is copied from the r8152 driver (v2.12.0) published by Realtek (www.realtek.com).

The length for such an OGM2 is BATADV_OGM2_HLEN + batadv_ogm2_packet->tvlv_len. The check must first check that at least BATADV_OGM2_HLEN bytes are available before it accesses tvlv_len (which is part of the header.

[ Upstream commit 90cf500e ] Currently, we are translating RPC level errors such as timeouts, as well as interrupts etc into EOPENSTALE, which forces a single replay of the open attempt. What we actually want to do is force the replay only in the cases where the returned error indicates that the file may have changed on the server. So the fix is to spell out the exact set of errors where we want to return EOPENSTALE. Signed-off-by:

[ Upstream commit 91b4db53 ] "p runtime/jit: pass > 32bit index to tail_call" fails when bpf_jit_enable=1, because the tail call is not executed. This in turn is because the generated code assumes index is 64-bit, while it must be 32-bit, and as a result prog array bounds check fails, while it should pass. Even if bounds check would have passed, the code that follows uses 64-bit index to compute prog array offset. Fix by using clrj instead of clgrj for comparing index with array size, and also by using llgfr for truncating index to 32 bits before using it to compute prog array offset.

[ Upstream commit bb2d267c ] "masking, test in bounds 3" fails on s390, because BPF_ALU64_IMM(BPF_NEG, BPF_REG_2, 0) ignores the top 32 bits of BPF_REG_2. The reason is that JIT emits lcgfr instead of lcgr. The associated comment indicates that the code was intended to emit lcgr in the first place, it's just that the wrong opcode was used. Fix by using the correct opcode. Fixes: 05462310 ("s390/bpf: Add s390x eBPF JIT compiler backend") Signed-off-by:

[ Upstream commit afd58b16 ] TRM says PWMSS_SYSCONFIG bit for SOFTRESET changes to zero when reset is completed. Let's configure it as otherwise we get warnings on boot when we check the data against dts provided data. Eventually the legacy platform data will be just dropped, but let's fix the warning first.

commit 7caac62e upstream. mwifiex_update_vs_ie(),mwifiex_set_uap_rates() and mwifiex_set_wmm_params() call memcpy() without checking the destination size.Since the source is given from user-space, this may trigger a heap buffer overflow. Fix them by putting the length check before performing memcpy(). This fix addresses CVE-2019-14814,CVE-2019-14815,CVE-2019-14816. Signed-off-by:

commit d2ace81b upstream. When half-duplex RS485 communication is used, after RX is started, TX tasklet still needs to be scheduled tasklet. This avoids console freezing when more data is to be transmitted, if the serial communication is not closed.

commit 9c801e31 upstream. The sequence of arguments which was passed to handle_lsr_errors() didn't match the parameters defined in that function, &lsr was passed to flag and &flag was passed to lsr, this patch fixed that.

commit b60fe990 upstream. The first/last indexes are typically shared with a user app. The app can change the 'last' index that the kernel uses to store the next result. This change sanity checks the index before using it for writing to a potentially arbitrary address. This fixes CVE-2019-14821.
