[ Upstream commit 3e82f2f3 ] During frame reception while the MCAN is in Error Passive state and the Receive Error Counter has thevalue MCAN_ECR.REC = 127, it may happen that MCAN_IR.MRAF is set although there was no Message RAM access failure. If MCAN_IR.MRAF is enabled, an interrupt to the Host CPU is generated. Work around: The Message RAM Access Failure interrupt routine needs to check whether MCAN_ECR.RP = '1' and MCAN_ECR.REC = '127'. In this case, reset MCAN_IR.MRAF. No further action is required. This affects versions older than 3.2.0 Errata explained on Sama5d2 SoC which includes this hardware block: http://ww1.microchip.com/downloads/en/DeviceDoc/SAMA5D2-Family-Silicon-Errata-and-Data-Sheet-Clarification-DS80000803B.pdf chapter 6.2 Reproducibility: If 2 devices with m_can are connected back to back, configuring different bitrate on them will lead to interrupt storm on the receiving side, with error "Message RAM access failure occurred". Another way is to have a bad hardware connection. Bad wire connection can lead to this issue as well. This patch fixes the issue according to provided workaround. Signed-off-by:

[ Upstream commit 8a3dca63 ] When fixing the skb leak introduced by the conversion to rbtree, I forgot about the special case of duplicate fragments. The condition under the 'insert_error' label isn't effective anymore as nf_ct_frg6_gather() doesn't override the returned value anymore. So duplicate fragments now get NF_DROP verdict. To accept duplicate fragments again, handle them specially as soon as inet_frag_queue_insert() reports them. Return -EINPROGRESS which will translate to NF_STOLEN verdict, like any accepted fragment. However, such packets don't carry any new information and aren't queued, so we just drop them immediately.

[ Upstream commit 1884c066 ] In commit 9a5ab8bf ("tools: bpftool: turn err() and info() macros into functions") one case of error reporting was special cased, so it could report a lookup error for a specific key when dumping the map element. What the code forgot to do is to wrap the key and value keys into a JSON object, so an example output of pretty JSON dump of a sockhash map (which does not support looking up its values) is: [ "key": ["0x0a","0x41","0x00","0x02","0x1f","0x78","0x00","0x00" ], "value": { "error": "Operation not supported" }, "key": ["0x0a","0x41","0x00","0x02","0x1f","0x78","0x00","0x01" ], "value": { "error": "Operation not supported" } ] Note the key-value pairs inside the toplevel array. They should be wrapped inside a JSON object, otherwise it is an invalid JSON. This commit fixes this, so the output now is: [{ "key": ["0x0a","0x41","0x00","0x02","0x1f","0x78","0x00","0x00" ], "value": { "error": "Operation not supported" } },{ "key": ["0x0a","0x41","0x00","0x02","0x1f","0x78","0x00","0x01" ], "value": { "error": "Operation not supported" } } ] Fixes: 9a5ab8bf ("tools: bpftool: turn err() and info() macros into functions") Cc: Quentin Monnet <quentin.monnet@netronome.com> Signed-off-by:

[ Upstream commit a0d56cb9 ] With commit 997dd964 ("net: IP6 defrag: use rbtrees in nf_conntrack_reasm.c"), nf_ct_frag6_reasm() is now called from nf_ct_frag6_queue(). With this change, nf_ct_frag6_queue() can fail after the skb has been added to the fragment queue and nf_ct_frag6_gather() was adapted to handle this case. But nf_ct_frag6_queue() can still fail before the fragment has been queued. nf_ct_frag6_gather() can't handle this case anymore, because it has no way to know if nf_ct_frag6_queue() queued the fragment before failing. If it didn't, the skb is lost as the error code is overwritten with -EINPROGRESS. Fix this by setting -EINPROGRESS directly in nf_ct_frag6_queue(), so that nf_ct_frag6_gather() can propagate the error as is.

[ Upstream commit 69ae4f6a ] A few places in mwifiex_uap_parse_tail_ies() perform memcpy() unconditionally, which may lead to either buffer overflow or read over boundary. This patch addresses the issues by checking the read size and the destination size at each place more properly. Along with the fixes, the patch cleans up the code slightly by introducing a temporary variable for the token size, and unifies the error path with the standard goto statement. Reported-by:

[ Upstream commit b3500b47 ] When we have a single image (same firmware image for INIT and OPERATIONAL), we couldn't load the driver and register to the stack if we had hardware RF-Kill asserted. Fix this. This required a few changes: 1) Run the firmware as part of the INIT phase even if its ucode_type is not IWL_UCODE_INIT. 2) Send the commands that are sent to the unified image in INIT flow even in RF-Kill. 3) Don't ask the transport to stop the hardware upon RF-Kill interrupt if the RF-Kill is asserted. 4) Allow the RF-Kill interrupt to take us out of L1A so that the RF-Kill interrupt will be received by the host (to enable the radio).

[ Upstream commit 1e692f09 ] In BPF, 32-bit ALU operations should zero-extend their results into the 64-bit registers. The current BPF JIT on RISC-V emits incorrect instructions that perform sign extension only (e.g., addw, subw) on 32-bit add, sub, lsh, rsh, arsh, and neg. This behavior diverges from the interpreter and JITs for other architectures. This patch fixes the bugs by performing zero extension on the destination register of 32-bit ALU operations.

[ Upstream commit bd95e678 ] Backlog work for psock (sk_psock_backlog) might sleep while waiting for memory to free up when sending packets. However, while sleeping the socket may be closed and removed from the map by the user space side. This breaks an assumption in sk_stream_wait_memory, which expects the wait queue to be still there when it wakes up resulting in a use-after-free shown below. To fix his mark sendmsg as MSG_DONTWAIT to avoid the sleep altogether. We already set the flag for the sendpage case but we missed the case were sendmsg is used. Sockmap is currently the only user of skb_send_sock_locked() so only the sockmap paths should be impacted. ================================================================== BUG: KASAN: use-after-free in remove_wait_queue+0x31/0x70 Write of size 8 at addr ffff888069a0c4e8 by task kworker/0:2/110 CPU: 0 PID: 110 Comm: kworker/0:2 Not tainted 5.0.0-rc2-00335-g28f9d1a3-dirty #14 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.10.2-2.fc27 04/01/2014 Workqueue: events sk_psock_backlog Call Trace: print_address_description+0x6e/0x2b0 ? remove_wait_queue+0x31/0x70 kasan_report+0xfd/0x177 ? remove_wait_queue+0x31/0x70 ? remove_wait_queue+0x31/0x70 remove_wait_queue+0x31/0x70 sk_stream_wait_memory+0x4dd/0x5f0 ? sk_stream_wait_close+0x1b0/0x1b0 ? wait_woken+0xc0/0xc0 ? tcp_current_mss+0xc5/0x110 tcp_sendmsg_locked+0x634/0x15d0 ? tcp_set_state+0x2e0/0x2e0 ? __kasan_slab_free+0x1d1/0x230 ? kmem_cache_free+0x70/0x140 ? sk_psock_backlog+0x40c/0x4b0 ? process_one_work+0x40b/0x660 ? worker_thread+0x82/0x680 ? kthread+0x1b9/0x1e0 ? ret_from_fork+0x1f/0x30 ? check_preempt_curr+0xaf/0x130 ? iov_iter_kvec+0x5f/0x70 ? kernel_sendmsg_locked+0xa0/0xe0 skb_send_sock_locked+0x273/0x3c0 ? skb_splice_bits+0x180/0x180 ? start_thread+0xe0/0xe0 ? update_min_vruntime.constprop.27+0x88/0xc0 sk_psock_backlog+0xb3/0x4b0 ? strscpy+0xbf/0x1e0 process_one_work+0x40b/0x660 worker_thread+0x82/0x680 ? process_one_work+0x660/0x660 kthread+0x1b9/0x1e0 ? __kthread_create_on_node+0x250/0x250 ret_from_fork+0x1f/0x30 Fixes: 20bf50de ("skbuff: Function to send an skbuf on a socket") Reported-by:

[ Upstream commit fe121ee5 ] When using 32-bit subregisters (ALU32), the RISC-V JIT would not clear the high 32-bits of the target register and therefore generate incorrect code. E.g., in the following code: $ cat test.c unsigned int f(unsigned long long a, unsigned int b) { return (unsigned int)a & b; } $ clang-9 -target bpf -O2 -emit-llvm -S test.c -o - | \ llc-9 -mattr=+alu32 -mcpu=v3 .text .file "test.c" .globl f .p2align 3 .type f,@function f: r0 = r1 w0 &= w2 exit .Lfunc_end0: .size f, .Lfunc_end0-f The JIT would not clear the high 32-bits of r0 after the and-operation, which in this case might give an incorrect return value. After this patch, that is not the case, and the upper 32-bits are cleared. Reported-by:

This fixes a NULL pointer de-reference with the code continuing without having a proper array of registers to use.

commit a1a42f84 upstream. The talitos driver has two ways to perform AEAD depending on the HW capability. Some HW support both. It is needed to give them different names to distingish which one it is for instance when a test fails. Signed-off-by:

commit 20a0f976 upstream. Commit c778f96b ("crypto: lrw - Optimize tweak computation") incorrectly reduced the alignmask of LRW instances from '__alignof__(u64) - 1' to '__alignof__(__be32) - 1'. However, xor_tweak() and setkey() assume that the data and key, respectively, are aligned to 'be128', which has u64 alignment. Fix the alignmask to be at least '__alignof__(be128) - 1'.

commit 5676234f upstream. WRITE SAME corrupts data on the block device behind iblock if the command is emulated. The emulation code issues (M - 1) * N times more bios than requested, where M is the number of 512 blocks per real block size and N is the NUMBER OF LOGICAL BLOCKS specified in WRITE SAME command. So, for a device with 4k blocks, 7 * N more LBAs gets written after the requested range. The issue happens because the number of 512 byte sectors to be written is decreased one by one while the real bios are typically from 1 to 8 512 byte sectors per bio.

commit 75f2d86b upstream. CONFIG_VALIDATE_FS_PARSER is a debugging tool to check that the parser tables are vaguely sane. It was set to default to 'Y' for the moment to catch errors in upcoming fs conversion development. Make sure it is not enabled by default in the final release of v5.1.

commit 4c89cc73 upstream. The "pending" variable was a u32 but we cast it to an unsigned long pointer when we do the for_each_set_bit() loop. The problem is that on big endian 64bit systems that results in an out of bounds read. Fixes: 4e4106f5 ("dmaengine: jz4780: Fix transfers being ACKed too soon") Signed-off-by:

commit 3f93a4f2 upstream. It is possible for an irq triggered by channel0 to be received later after clks are disabled once firmware loaded during sdma probe. If that happens then clearing them by writing to SDMA_H_INTR won't work and the kernel will hang processing infinite interrupts. Actually, don't need interrupt triggered on channel0 since it's pollling SDMA_H_STATSTOP to know channel0 done rather than interrupt in current code, just clear BD_INTR to disable channel0 interrupt to avoid the above case. This issue was brought by commit 1d069bfa ("dmaengine: imx-sdma: ack channel 0 IRQ in the interrupt handler") which didn't take care the above case.

commit 0b24cae4 upstream. Add a missing EHB (Execution Hazard Barrier) in mtc0 -> mfc0 sequence. Without this execution hazard barrier it's possible for the value read back from the KScratch register to be the value from before the mtc0. Reproducible on P5600 & P6600. The hazard is documented in the MIPS Architecture Reference Manual Vol. III: MIPS32/microMIPS32 Privileged Resource Architecture (MD00088), rev 6.03 table 8.1 which includes: Producer | Consumer | Hazard ----------|----------|---------------------------- mtc0 | mfc0 | any coprocessor 0 register Signed-off-by:

commit d6ed083f upstream. The bounds check used the uninitialized variable vaddr, it should use the given parameter kaddr instead. When using the uninitialized value the compiler assumed it to be 0 and optimized this function to just return 0 in all cases. This should make the function check the range of the given address and only do the page map check in case it is in the expected range of virtual addresses.
