A contact at Realtek has clarified what exactly the units of RGMII RX delay are. The answer is that the unit of RX delay is "about 0.3 ns". Take this into account when parsing rx-internal-delay-ps by approximating the closest step value. Delays of more than 2.1 ns are rejected. This obviously contradicts the previous assumption in the driver that a step value of 4 was "about 2 ns", but Realtek also points out that it is easy to find more than one RX delay step value which makes RGMII work.

Stephan Gerhold says: ==================== net: wwan: Add Qualcomm BAM-DMUX WWAN network driver The BAM Data Multiplexer provides access to the network data channels of modems integrated into many older Qualcomm SoCs, e.g. Qualcomm MSM8916 or MSM8974. This series adds a driver that allows using it. All the changes in this patch series are based on a quite complicated driver from Qualcomm [1]. The driver has been used in postmarketOS [2] on various smartphones/tablets based on Qualcomm MSM8916 and MSM8974 for more than a year now with no reported problems. It works out of the box with open-source WWAN userspace such as ModemManager.

The BAM Data Multiplexer provides access to the network data channels of modems integrated into many older Qualcomm SoCs, e.g. Qualcomm MSM8916 or MSM8974. It is built using a simple protocol layer on top of a DMA engine (Qualcomm BAM) and bidirectional interrupts to coordinate power control. The modem announces a fixed set of channels by sending an OPEN command. The driver exports each channel as separate network interface so that a connection can be established via QMI from userspace. The network interface can work either in Ethernet or Raw-IP mode (configurable via QMI). However, Ethernet mode seems to be broken with most firmwares (network packets are actually received as Raw-IP), therefore the driver only supports Raw-IP mode. Note that the control channel (QMI/AT) is entirely separate from BAM-DMUX and is already supported by the RPMSG_WWAN_CTRL driver. The driver uses runtime PM to coordinate power control with the modem. TX/RX buffers are put in a kind of "ring queue" and submitted via the bam_dma driver of the DMAEngine subsystem. The basic architecture looks roughly like this: +------------+ +-------+ [IPv4/6] | BAM-DMUX | | | [Data...] | | | | ---------->|wwan0 | [DMUX chan: x] | | [IPv4/6] | (chan: 0) | [IPv4/6] | | [Data...] | | [Data...] | | ---------->|wwan1 |--------------->| Modem | | (chan: 1) | BAM | | [IPv4/6] | ... | (DMA Engine) | | [Data...] | | | | ---------->|wwan7 | | | | (chan: 7) | | | +------------+ +-------+ Note that some newer firmware versions support QMAP ("rmnet" driver) as additional multiplexing layer on top of BAM-DMUX, but this is not currently supported by this driver.

The writer acquires dev_base_lock with disabled bottom halves. The reader can acquire dev_base_lock without disabling bottom halves because there is no writer in softirq context. On PREEMPT_RT the softirqs are preemptible and local_bh_disable() acts as a lock to ensure that resources, that are protected by disabling bottom halves, remain protected. This leads to a circular locking dependency if the lock acquired with disabled bottom halves (as in write_lock_bh()) and somewhere else with enabled bottom halves (as by read_lock() in netstat_show()) followed by disabling bottom halves (cxgb_get_stats() -> t4_wr_mbox_meat_timeout() -> spin_lock_bh()). This is the reverse locking order. All read_lock() invocation are from sysfs callback which are not invoked from softirq context. Therefore there is no need to disable bottom halves while acquiring a write lock. Acquire the write lock of dev_base_lock without disabling bottom halves. Reported-by:

Previously commit e02d494d ("l2tp: Convert rwlock to RCU") converted most, but not all, rwlock instances in the l2tp subsystem to RCU. The remaining rwlock protects the per-tunnel hashlist of sessions which is used for session lookups in the UDP-encap data path. Convert the remaining rwlock to rcu to improve performance of UDP-encap tunnels. Note that the tunnel and session, which both live on RCU-protected lists, use slightly different approaches to incrementing their refcounts in the various getter functions. The tunnel has to use refcount_inc_not_zero because the tunnel shutdown process involves dropping the refcount to zero prior to synchronizing RCU readers (via. kfree_rcu). By contrast, the session shutdown removes the session from the list(s) it is on, synchronizes with readers, and then decrements the session refcount. Since the getter functions increment the session refcount with the RCU read lock held we prevent getters seeing a zero session refcount, and therefore don't need to use refcount_inc_not_zero.

Maxime Chevallier says: ==================== net: mvneta: mqprio cleanups and shaping support This is the second version of the series that adds some improvements to the existing mqprio implementation in mvneta, and adds support for egress shaping offload. The first 3 patches are some minor cleanups, such as using the tc_mqprio_qopt_offload structure to get access to more offloading options, cleaning the logic to detect whether or not we should offload mqprio setting, and allowing to have a 1 to N mapping between TCs and queues. The last patch adds traffic shaping offload, using mvneta's per-queue token buckets, allowing to limit rates from 10Kbps up to 5Gbps with 10Kbps increments. This was tested only on an Armada 3720, with traffic up to 2.5Gbps. Changes since V1 fixes the build for 32bits kernels, using the right div helpers as suggested by Jakub. ==================== Signed-off-by: -
Maxime Chevallier authored
The mvneta controller is able to do some tocken-bucket per-queue traffic shaping. This commit adds support for setting these using the TC mqprio interface. The token-bucket parameters are customisable, but the current implementation configures them to have a 10kbps resolution for the rate limitation, since it allows to cover the whole range of max_rate values from 10kbps to 5Gbps with 10kbps increments.

The current mqprio implementation assumed that we are only using one queue per TC. Use the offset and count parameters to allow using multiple queues per TC. In that case, the controller will use a standard round-robin algorithm to pick queues assigned to the same TC, with the same priority. This only applies to VLAN priorities in ingress traffic, each TC corresponding to a vlan priority. Signed-off-by:

This series replaces it with small per-hash locks. 1st - 2nd : Misc refactoring 3rd - 8th : Separate BSD/abstract address logics 9th - 11th : Prep to save a hash in each socket 12th : Replace the big lock 13th : Speed up autobind() Note to maintainers: The 12th patch adds two kinds of Sparse warnings on patchwork: about unix_table_double_lock/unlock() We can avoid this by adding two apparent acquires/releases annotations, but there are the same kinds of warnings about unix_state_double_lock(). about unix_next_socket() and unix_seq_stop() (/proc/net/unix) This is because Sparse does not understand logic in unix_next_socket(), which leaves a spin lock held until it returns NULL. Also, tcp_seq_stop() causes a warning for the same reason. These warnings seem reasonable, but let me know if there is any better way. Please see [0] for details.

When we bind an AF_UNIX socket without a name specified, the kernel selects an available one from 0x00000 to 0xFFFFF. unix_autobind() starts searching from a number in the 'static' variable and increments it after acquiring two locks. If multiple processes try autobind, they obtain the same lock and check if a socket in the hash list has the same name. If not, one process uses it, and all except one end up retrying the _next_ number (actually not, it may be incremented by the other processes). The more we autobind sockets in parallel, the longer the latency gets. We can avoid such a race by searching for a name from a random number. These show latency in unix_autobind() while 64 CPUs are simultaneously autobind-ing 1024 sockets for each.

The hash table of AF_UNIX sockets is protected by the single lock. This patch replaces it with per-hash locks. The effect is noticeable when we handle multiple sockets simultaneously. Here is a test result on an EC2 c5.24xlarge instance. It shows latency (under 10us only) in unix_insert_unbound_socket() while 64 CPUs creating 1024 sockets for each in parallel.

To replace unix_table_lock with per-hash locks in the next patch, we need to save a hash in each socket because /proc/net/unix or BPF prog iterate sockets while holding a hash table lock and release it later in a different function. Currently, we store a real/pseudo hash in struct unix_address. However, we do not allocate it to unbound sockets, nor should we do just for that. For this purpose, we can use sk_hash. Then, we no longer use the hash field in struct unix_address and can remove it. Also, this patch does - rename unix_insert_socket() to unix_insert_unbound_socket() - remove the redundant list argument from __unix_insert_socket() and unix_insert_unbound_socket() - use 'unsigned int' instead of 'unsigned' in __unix_set_addr_hash() - remove 'inline' from unix_remove_socket() and unix_insert_unbound_socket().

In BSD and abstract address cases, we store sockets in the hash table with keys between 0 and UNIX_HASH_SIZE - 1. However, the hash saved in a socket varies depending on its address type; sockets with BSD addresses always have UNIX_HASH_SIZE in their unix_sk(sk)->addr->hash. This is just for the UNIX_ABSTRACT() macro used to check the address type. The difference of the saved hashes comes from the first byte of the address in the first place. So, we can test it directly. Then we can keep a real hash in each socket and replace unix_table_lock with per-hash locks in the later patch. Signed-off-by:

To terminate address with '\0' in unix_bind_bsd(), we add unix_create_addr() and call it in unix_bind_bsd() and unix_bind_abstract(). Also, unix_bind_abstract() does not return -EEXIST. Only kern_path_create() and vfs_mknod() in unix_bind_bsd() can return it, so we move the last error check in unix_bind() to unix_bind_bsd(). Signed-off-by:

Kuniyuki Iwashima authored
unix_mkname() tests socket address length and family and does some processing based on the address type. It is called in the early stage, and therefore some instructions are redundant and can end up in vain. The address length/family tests are done twice in unix_bind(). Also, the address type is rechecked later in unix_bind() and unix_find_other(), where we can do the same processing. Moreover, in the BSD address case, the hash is set to 0 but never used and confusing. This patch moves the address tests out of unix_mkname(), and the following patches move the other part into appropriate places and remove unix_mkname() finally. Signed-off-by:

The length of the AF_UNIX socket address contains an offset to the member sun_path of struct sockaddr_un. Currently, the preceding member is just sun_family, and its type is sa_family_t and resolved to short. Therefore, the offset is represented by sizeof(short). However, it is not clear and fragile to changes in struct sockaddr_storage or sockaddr_un. This commit makes it clear and robust by rewriting sizeof() with offsetof(). Signed-off-by:
