As its implementation shows, this is synonimous with calling dsa_slave_dev_check followed by dsa_slave_to_port, so it is quite simple already and provides functionality which is already there. However there is now a need for these functions outside dsa_priv.h, for example in drivers that perform mirroring and redirection through tc-flower offloads (they are given raw access to the flow_cls_offload structure), where they need to call this function on act->dev. But simply exporting dsa_slave_to_port would make it non-inline and would result in an extra function call in the hotpath, as can be seen for example in sja1105: Before: 000006dc <sja1105_xmit>: { 6dc: e92d4ff0 push {r4, r5, r6, r7, r8, r9, sl, fp, lr} 6e0: e1a04000 mov r4, r0 6e4: e591958c ldr r9, [r1, #1420] ; 0x58c <- Inline dsa_slave_to_port 6e8: e1a05001 mov r5, r1 6ec: e24dd004 sub sp, sp, #4 u16 tx_vid = dsa_8021q_tx_vid(dp->ds, dp->index); 6f0: e1c901d8 ldrd r0, [r9, #24] 6f4: ebfffffe bl 0 <dsa_8021q_tx_vid> 6f4: R_ARM_CALL dsa_8021q_tx_vid u8 pcp = netdev_txq_to_tc(netdev, queue_mapping); 6f8: e1d416b0 ldrh r1, [r4, #96] ; 0x60 u16 tx_vid = dsa_8021q_tx_vid(dp->ds, dp->index); 6fc: e1a08000 mov r8, r0 After: 000006e4 <sja1105_xmit>: { 6e4: e92d4ff0 push {r4, r5, r6, r7, r8, r9, sl, fp, lr} 6e8: e1a04000 mov r4, r0 6ec: e24dd004 sub sp, sp, #4 struct dsa_port *dp = dsa_slave_to_port(netdev); 6f0: e1a00001 mov r0, r1 { 6f4: e1a05001 mov r5, r1 struct dsa_port *dp = dsa_slave_to_port(netdev); 6f8: ebfffffe bl 0 <dsa_slave_to_port> 6f8: R_ARM_CALL dsa_slave_to_port 6fc: e1a09000 mov r9, r0 u16 tx_vid = dsa_8021q_tx_vid(dp->ds, dp->index); 700: e1c001d8 ldrd r0, [r0, #24] 704: ebfffffe bl 0 <dsa_8021q_tx_vid> 704: R_ARM_CALL dsa_8021q_tx_vid Because we want to avoid possible performance regressions, introduce this new function which is designed to be public.

Manivannan Sadhasivam says: ==================== Add QRTR MHI client driver Here is the series adding MHI client driver support to Qualcomm IPC router protocol. MHI is a newly added bus to kernel which is used to communicate to external modems over a physical interface like PCI-E. This driver is used to transfer the QMI messages between the host processor and external modems over the "IPCR" channel. For QRTR, this driver is just another driver acting as a transport layer like SMD. Currently this driver is needed to control the QCA6390 WLAN device from ath11k. The ath11k MHI controller driver will take care of booting up QCA6390 and bringing it to operating state. Later, this driver will be used to transfer QMI messages over the MHI-IPCR channel. The second patch of this series removes the ARCH_QCOM dependency for QRTR. This is needed because the QRTR driver will be used with x86 machines as well to talk to devices like QCA6390. ==================== Signed-off-by: -

IPC Router protocol is also used by external modems for exchanging the QMI messages. Hence, it doesn't always depend on Qualcomm platforms. One such instance is the QCA6390 WLAN device connected to x86 machine. Reviewed-by:

This patch adds FLOW_ACTION_HW_STATS_DONT_CARE which tells the driver that the frontend does not need counters, this hw stats type request never fails. The FLOW_ACTION_HW_STATS_DISABLED type explicitly requests the driver to disable the stats, however, if the driver cannot disable counters, it bails out. TCA_ACT_HW_STATS_* maintains the 1:1 mapping with FLOW_ACTION_HW_STATS_* except by disabled which is mapped to FLOW_ACTION_HW_STATS_DISABLED (this is 0 in tc). Add tc_act_hw_stats() to perform the mapping between TCA_ACT_HW_STATS_* and FLOW_ACTION_HW_STATS_*. Fixes: 319a1d19 ("flow_offload: check for basic action hw stats type") Signed-off-by:

Jason A. Donenfeld says: ==================== wireguard fixes for 5.7-rc5 With Ubuntu and Debian having backported this into their kernels, we're finally seeing testing from places we hadn't seen prior, which is nice. With that comes more fixes: 1) The CI for PPC64 was running with extremely small stacks for 64-bit, causing spurious crashes in surprising places. 2) There's was an old leftover routing loop restriction, which no longer makes sense given the queueing architecture, and was causing problems for people who really did want nested routing. 3) Not yielding our kthread on CONFIG_PREEMPT_VOLUNTARY systems caused RCU stalls and other issues, reported by Wang Jian, with the fix suggested by Sultan Alsawaf. 4) Clang spewed warnings in a selftest for CONFIG_IPV6=n, reported by Arnd Bergmann. 5) A complicated if statement was simplified to an assignment while also making the likely/unlikely hinting more correct and simple, and increasing readability, suggested by Sultan. Patches (2) and (3) have Fixes: lines and are probably good candidates for stable. ==================== Signed-off-by: -

It's very unlikely that send will become true. It's nearly always false between 0 and 120 seconds of a session, and in most cases becomes true only between 120 and 121 seconds before becoming false again. So, unlikely(send) is clearly the right option here. What happened before was that we had this complex boolean expression with multiple likely and unlikely clauses nested. Since this is evaluated left-to-right anyway, the whole thing got converted to unlikely. So, we can clean this up to better represent what's going on. The generated code is the same. Suggested-by:

Users with pathological hardware reported CPU stalls on CONFIG_ PREEMPT_VOLUNTARY=y, because the ringbuffers would stay full, meaning these workers would never terminate. That turned out not to be okay on systems without forced preemption, which Sultan observed. This commit adds a cond_resched() to the bottom of each loop iteration, so that these workers don't hog the core. Note that we don't need this on the napi poll worker, since that terminates after its budget is expended. Suggested-by:

Jason A. Donenfeld authored
It's already possible to create two different interfaces and loop packets between them. This has always been possible with tunnels in the kernel, and isn't specific to wireguard. Therefore, the networking stack already needs to deal with that. At the very least, the packet winds up exceeding the MTU and is discarded at that point. So, since this is already something that happens, there's no need to forbid the not very exceptional case of routing a packet back to the same interface; this loop is no different than others, and we shouldn't special case it, but rather rely on generic handling of loops in general. This also makes it easier to do interesting things with wireguard such as onion routing. At the same time, we add a selftest for this, ensuring that both onion routing works and infinite routing loops do not crash the kernel. We also add a test case for wireguard interfaces nesting packets and sending traffic between each other, as well as the loop in this case too. We make sure to send some throughput-heavy traffic for this use case, to stress out any possible recursion issues with the locks around workqueues.

While at some point it might have made sense to be running these tests on ppc64 with 4k stacks, the kernel hasn't actually used 4k stacks on 64-bit powerpc in a long time, and more interesting things that we test don't really work when we deviate from the default (16k). So, we stop pushing our luck in this commit, and return to the default instead of the minimum. Signed-off-by:

This UAPI is needed for BroadR-Reach 100BASE-T1 devices. Due to lack of auto-negotiation support, we needed to be able to configure the MASTER-SLAVE role of the port manually or from an application in user space. The same UAPI can be used for 1000BASE-T or MultiGBASE-T devices to force MASTER or SLAVE role.

This solves the following issues observed during self test when CONFIG_CRYPTO_MANAGER_EXTRA_TESTS is enabled. 1. Added fallback for cbc, ctr and rfc3686 if req->nbytes is zero and for xts added a fallback case if req->nbytes is not multiple of 16. 2. In case of cbc-aes, solved wrong iv update. When chcr_cipher_fallback() is called, used req->info pointer instead of reqctx->iv. 3. In cbc-aes decryption there was a wrong result. This occurs when chcr_cipher_fallback() is called from chcr_handle_cipher_resp(). In the fallback function iv(req->info) used is wrongly updated. So use the initial iv for this case. 4)In case of ctr-aes encryption observed wrong result. In adjust_ctr_overflow() there is condition which checks if ((bytes / AES_BLOCK_SIZE) > c), where c is the number of blocks which can be processed without iv overflow, but for the above bytes (req->nbytes < 32 , not a multiple of 16) this condition fails and the 2nd block is corrupted as it requires the rollover iv. So added a '=' condition in this to take care of this. 5)In rfc3686-ctr there was wrong result observed. This occurs when chcr_cipher_fallback() is called from chcr_handle_cipher_resp(). Here also copying initial_iv in init_iv pointer for handling the fallback case correctly. Signed-off-by:

This patch fixes two issues observed during self tests with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS enabled. 1. gcm(aes) hang issue , that happens during decryption. 2. rfc4106-gcm-aes-chcr encryption unexpectedly succeeded. For gcm-aes decryption , authtag is not mapped due to sg_nents_for_len(upto size: assoclen+ cryptlen - authsize). So fix it by dma_mapping authtag. Also replaced sg_nents() to sg_nents_for_len() in case of aead_dma_unmap(). For rfc4106-gcm-aes-chcr, used crypto_ipsec_check_assoclen() for checking the validity of assoclen. Signed-off-by:
