[ Upstream commit dcd9c76e ] When enabling IOMMU support, the following issue becomes visible in the AEAD zero-length case. Even though the output sequence length is set to zero, the crypto engine tries to prefetch 4 S/G table entries (since SGF bit is set in SEQ OUT PTR command - which is either generated in SW in case of caam/jr or in HW in case of caam/qi, caam/qi2). The DMA read operation will trigger an IOMMU fault since the address in the SEQ OUT PTR is "dummy" (set to zero / not obtained via DMA API mapping). 1. In case of caam/jr, avoid the IOMMU fault by clearing the SGF bit in SEQ OUT PTR command. 2. In case of caam/qi - setting address, bpid, length to zero for output entry in the compound frame has a special meaning (cf. CAAM RM): "Output frame = Unspecified, Input address = Y. A unspecified frame is indicated by an unused SGT entry (an entry in which the Address, Length, and BPID fields are all zero). SEC obtains output buffers from BMan as prescribed by the preheader." Since no output buffers are needed, modify the preheader by setting (ABS = 1, ADDBUF = 0): -"ABS = 1 means obtain the number of buffers in ADDBUF (0 or 1) from the pool POOL ID" -ADDBUF: "If ABS is set, ADD BUF specifies whether to allocate a buffer or not" 3. In case of caam/qi2, since engine: -does not support FLE[FMT]=2'b11 ("unused" entry) mentioned in DPAA2 RM -requires output entry to be present, even if not used the solution chosen is to leave output frame list entry zeroized.

[ Upstream commit 0c7aa329 ] The commit d790b7ed ("[media] vb2-dma-sg: move dma_(un)map_sg here") left dma_desc_nent unset. It previously contained the number of DMA descriptors as returned from dma_map_sg(). We can now (since the commit referred to above) obtain the same value from the sg_table and drop dma_desc_nent altogether. Tested on OLPC XO-1.75 machine. Doesn't affect the OLPC XO-1's Cafe driver, since that one doesn't do DMA.

[ Upstream commit e10b0edd ] Interrupt is set in ICM (ICR & ~IMV) rising trigger. As the driver masks the IRQ after clearing it, there can be a race where an additional spurious interrupt is triggered when the driver unmask the IRQ. This can happen in case HW triggers an interrupt after the clear and before the mask. To prevent the second spurious interrupt the driver needs to mask the IRQ before reading and clearing it.

[ Upstream commit 49ed34b8 ] For some SDIO chip, the peer id is 65535 for MPDU with error status, then test_bit will trigger buffer overflow for peer's memory, if kasan enabled, it will report error. Reason is when station is in disconnecting status, firmware do not delete the peer info since it not disconnected completely, meanwhile some AP will still send data packet to station, then hardware will receive the packet and send to firmware, firmware's logic will report peer id of 65535 for MPDU with error status. Add check for overflow the size of peer's peer_ids will avoid the buffer overflow access.

[ Upstream commit 5d6751ea ] The "ev->traffic_class" and "reply->ac" variables come from the network and they're used as an offset into the wmi->stream_exist_for_ac[] array. Those variables are u8 so they can be 0-255 but the stream_exist_for_ac[] array only has WMM_NUM_AC (4) elements. We need to add a couple bounds checks to prevent array overflows. I also modified one existing check from "if (traffic_class > 3) {" to "if (traffic_class >= WMM_NUM_AC) {" just to make them all consistent.

[ Upstream commit 7441be71 ] When MISC interrupt is triggered due to HALP bit, in parallel to mbox events handling by the MISC threaded IRQ, new mbox interrupt can be missed in the following scenario: 1. MISC ICR is read in the IRQ handler 2. Threaded IRQ is completed and all MISC interrupts are unmasked 3. mbox interrupt is set by FW 4. HALP is masked The mbox interrupt in step 3 can be missed due to constant high level of ICM. Masking all MISC IRQs instead of masking only HALP bit in step 4 will guarantee that ICM will drop to 0 and interrupt will be triggered once MISC interrupts will be unmasked. Signed-off-by:

[ Upstream commit 47300728 ] This fixes tx and bi-directional dma transfers on rk3399-gru-kevin. It seems the SPI fifo must have room for 2 bursts when the dma_tx_req signal is generated or it might skip some words. This in turn makes the rx dma channel never complete for bi-directional transfers. Fix it by setting tx burst length to fifo_len / 4 and the dma watermark to fifo_len / 2. However the rk3399 TRM says (sic): "DMAC support incrementing-address burst and fixed-address burst. But in the case of access SPI and UART at byte or halfword size, DMAC only support fixed-address burst and the address must be aligned to word." So this relies on fifo_len being a multiple of 16 such that the burst length (= fifo_len / 4) is a multiple of 4 and the addresses will be word-aligned.

[ Upstream commit 2b8066c3 ] If probe() fails anywhere beyond the point where sdma_get_firmware() is called, then a kernel oops may occur. Problematic sequence of events: 1. probe() calls sdma_get_firmware(), which schedules the firmware callback to run when firmware becomes available, using the sdma instance structure as the context 2. probe() encounters an error, which deallocates the sdma instance structure 3. firmware becomes available, firmware callback is called with deallocated sdma instance structure 4. use after free - kernel oops ! Solution: only attempt to load firmware when we're certain that probe() will succeed. This guarantees that the firmware callback's context will remain valid. Note that the remove() path is unaffected by this issue: the firmware loader will increment the driver module's use count, ensuring that the module cannot be unloaded while the firmware callback is pending or running.

[ Upstream commit aa69fb62 ] After r363059 and r363928 in LLVM, a build using ld.lld as the linker with CONFIG_RANDOMIZE_BASE enabled fails like so: ld.lld: error: relocation R_AARCH64_ABS32 cannot be used against symbol __efistub_stext_offset; recompile with -fPIC Fangrui and Peter figured out that ld.lld is incorrectly considering __efistub_stext_offset as a relative symbol because of the order in which symbols are evaluated. _text is treated as an absolute symbol and stext is a relative symbol, making __efistub_stext_offset a relative symbol. Adding ABSOLUTE will force ld.lld to evalute this expression in the right context and does not change ld.bfd's behavior. ld.lld will need to be fixed but the developers do not see a quick or simple fix without some research (see the linked issue for further explanation). Add this simple workaround so that ld.lld can continue to link kernels.

[ Upstream commit db13a5ba ] While trying to get the uart with parity working I found setting even parity enabled odd parity insted. Fix the register settings to match the datasheet of AR9331. A similar patch was created by 8devices, but not sent upstream. https://github.com/8devices/openwrt-8devices/commit/77c5586ade3bb72cda010afad3f209ed0c98ea7cSigned-off-by:

commit e52d484d upstream. System gets checkstop if RxFIFO overruns with more requests than the maximum possible number of CRBs in FIFO at the same time. The max number of requests per window is controlled by window credits. So find max CRBs from FIFO size and set it to receive window credits.

commit 58cdbc6d upstream. On SEC1, hash provides wrong result when performing hashing in several steps with input data SG list has more than one element. This was detected with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS: [ 44.185947] alg: hash: md5-talitos test failed (wrong result) on test vector 6, cfg="random: may_sleep use_finup src_divs=[<reimport>25.88%@+8063, <flush>24.19%@+9588, 28.63%@+16333, <reimport>4.60%@+6756, 16.70%@+16281] dst_divs=[71.61%@alignmask+16361, 14.36%@+7756, 14.3%@+" [ 44.325122] alg: hash: sha1-talitos test failed (wrong result) on test vector 3, cfg="random: inplace use_final src_divs=[<flush,nosimd>16.56%@+16378, <reimport>52.0%@+16329, 21.42%@alignmask+16380, 10.2%@alignmask+16380] iv_offset=39" [ 44.493500] alg: hash: sha224-talitos test failed (wrong result) on test vector 4, cfg="random: use_final nosimd src_divs=[<reimport>52.27%@+7401, <reimport>17.34%@+16285, <flush>17.71%@+26, 12.68%@+10644] iv_offset=43" [ 44.673262] alg: hash: sha256-talitos test failed (wrong result) on test vector 4, cfg="random: may_sleep use_finup src_divs=[<reimport>60.6%@+12790, 17.86%@+1329, <reimport>12.64%@alignmask+16300, 8.29%@+15, 0.40%@+13506, <reimport>0.51%@+16322, <reimport>0.24%@+16339] dst_divs" This is due to two issues: - We have an overlap between the buffer used for copying the input data (SEC1 doesn't do scatter/gather) and the chained descriptor. - Data copy is wrong when the previous hash left less than one blocksize of data to hash, implying a complement of the previous block with a few bytes from the new request. Fix it by: - Moving the second descriptor after the buffer, as moving the buffer after the descriptor would make it more complex for other cipher operations (AEAD, ABLKCIPHER) - Skip the bytes taken from the new request to complete the previous one by moving the SG list forward.

commit ac6639cd upstream. Current code sets the dsci to 0x00000080. Which doesn't make any sense, as the indicator area is located in the _left-most_ byte. Worse: if the dsci is the _shared_ indicator, this potentially clears the indication of activity for a _different_ device. tiqdio_thinint_handler() will then have no reason to call that device's IRQ handler, and the device ends up stalling.

commit e54e4785 upstream. When tiqdio_remove_input_queues() removes a queue from the tiq_list as part of qdio_shutdown(), it doesn't re-initialize the queue's list entry and the prev/next pointers go stale. If a subsequent qdio_establish() fails while sending the ESTABLISH cmd, it calls qdio_shutdown() again in QDIO_IRQ_STATE_ERR state and tiqdio_remove_input_queues() will attempt to remove the queue entry a second time. This dereferences the stale pointers, and bad things ensue. Fix this by re-initializing the list entry after removing it from the list. For good practice also initialize the list entry when the queue is first allocated, and remove the quirky checks that papered over this omission. Note that prior to commit e5218134 ("s390/qdio: fix access to uninitialized qdio_q fields"), these checks were bogus anyway. setup_queues_misc() clears the whole queue struct, and thus needs to re-init the prev/next pointers as well.
