2019-04-22 On drivers which use MII(4) and have hook SIOC[GS]IFMEDIA which just pass tomsaitoh
ifmedia_ioctl(), the hook is not required because ether_ioctl has it (if_ethersubr.c rev. 1.160). These drivers don't return ENETRESET in ifmedia_ioctl(), so no functional change.
2019-01-22 Change MII PHY read/write API from:msaitoh
int (*mii_readreg_t)(device_t, int, int); void (*mii_writereg_t)(device_t, int, int, int); to: int (*mii_readreg_t)(device_t, int, int, uint16_t *); int (*mii_writereg_t)(device_t, int, int, uint16_t); Now we can test if a read/write operation failed or not by the return value. In 802.3 spec says that the PHY shall not respond to read/write transaction to the unimplemented register(22.2.4.3). Detecting timeout can be used to check whether a register is implemented or not (if the register conforms to the spec). ukphy(4) can be used this for MII_MMDACR and MII_MMDAADR. Note that I noticed that the following code do infinite loop in the read/wirte function. If it accesses unimplemented PHY register, it will hang. It should be fixed: arm/at91/at91emac.c arm/ep93xx/epe.c arm/omap/omapl1x_emac.c mips/ralink/ralink_eth.c arch/powerpc/booke/dev/pq3etsec.c(read) dev/cadence/if_cemac.c <- hkenken dev/ic/lan9118.c Tested with the following device: axe+ukphy axe+rgephy axen+rgephy (tested by Andrius V) wm+atphy wm+ukphy wm+igphy wm+ihphy wm+makphy sk+makphy sk+brgphy sk+gentbi msk+makphy sip+icsphy sip+ukphy re+rgephy bge+brgphy bnx+brgphy gsip+gphyter rtk+rlphy fxp+inphy (tested by Andrius V) tlp+acphy ex+exphy epic+qsphy vge+ciphy (tested by Andrius V) vr+ukphy (tested by Andrius V) vte+ukphy (tested by Andrius V) Not tested (MAC): arm:at91emac arm:cemac arm:epe arm:geminigmac arm:enet arm:cpsw arm:emac(omac) arm:emac(sunxi) arm:npe evbppc:temac macppc:bm macppc:gm mips:aumac mips:ae mips:cnmac mips:reth mips:sbmac playstation2:smap powerpc:tsec powerpc:emac(ibm4xx) sgimips:mec sparc:be sf ne(ax88190, dl10019) awge ep gem hme smsh mtd sm age alc ale bce cas et jme lii nfe pcn ste stge tl xi aue mue smsc udav url Not tested (PHY): amhphy bmtphy dmphy etphy glxtphy ikphy iophy lxtphy nsphyter pnaphy rdcphy sqphy tlphy tqphy urlphy
2018-06-26 Implement the BPF direction filter (BIOC[GS]DIRECTION). It provides backwardmsaitoh
compatibility with BIOC[GS]SEESENT ioctl. The userland interface is the same as FreeBSD. This change also fixes a bug that the direction is misunderstand on some environment by passing the direction to bpf_mtap*() instead of checking m->m_pkthdr.rcvif.
2017-05-23Apply deferred if_start to more driversozaki-r
And annotate some XXX_start as it runs in softint to clarify that it doesn't need deferred if_start.
2016-12-15Move bpf_mtap and if_ipackets++ on Rx of each driver to percpuq if_inputozaki-r
The benefits of the change are: - We can reduce codes - We can provide the same behavior between drivers - Where/When if_ipackets is counted up - Note that some drivers still update packet statistics in their own way (periodical update) - Moved bpf_mtap run in softint - This makes it easy to MP-ify bpf Proposed on tech-kern and tech-net

2016-06-10Introduce m_set_rcvif and m_reset_rcvifozaki-r
The API is used to set (or reset) a received interface of a mbuf. They are counterpart of m_get_rcvif, which will come in another commit, hide internal of rcvif operation, and reduce the diff of the upcoming change. No functional change.
2016-02-09Introduce softint-based if_inputozaki-r
This change intends to run the whole network stack in softint context (or normal LWP), not hardware interrupt context. Note that the work is still incomplete by this change; to that end, we also have to softint-ify if_link_state_change (and bpf) which can still run in hardware interrupt. This change softint-ifies at ifp->if_input that is called from each device driver (and ieee80211_input) to ensure Layer 2 runs in softint (e.g., ether_input and bridge_input). To this end, we provide a framework (called percpuq) that utlizes softint(9) and percpu ifqueues. With this patch, rxintr of most drivers just queues received packets and schedules a softint, and the softint dequeues packets and does rest packet processing. To minimize changes to each driver, percpuq is allocated in struct ifnet for now and that is initialized by default (in if_attach). We probably have to move percpuq to softc of each driver, but it's future work. At this point, only wm(4) has percpuq in its softc as a reference implementation. Additional information including performance numbers can be found in the thread at tech-kern@ and tech-net@: http://mail-index.netbsd.org/tech-kern/2016/01/14/msg019997.html Acknowledgment: riastradh@ greatly helped this work. Thank you very much!

2012-02-02Entropy-pool implementation move and cleanup.tls
1) Move core entropy-pool code and source/sink/sample management code to sys/kern from sys/dev. 2) Remove use of NRND as test for presence of entropy-pool code throughout source tree. 3) Remove use of RND_ENABLED in device drivers as microoptimization to avoid expensive operations on disabled entropy sources; make the rnd_add calls do this directly so all callers benefit. 4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might have lead to slight entropy overestimation for some sources. 5) Add new source types for environmental sensors, power sensors, VM system events, and skew between clocks, with a sample implementation for each. ok releng to go in before the branch due to the difficulty of later pullup (widespread #ifdef removal and moved files). Tested with release builds on amd64 and evbarm and live testing on amd64.

2010-01-19Redefine bpf linkage through an always present op vector, i.e.pooka
#if NBPFILTER is no longer required in the client. This change doesn't yet add support for loading bpf as a module, since drivers can register before bpf is attached. However, callers of bpf can now be modularized. Dynamically loadable bpf could probably be done fairly easily with coordination from the stub driver and the real driver by registering attachments in the stub before the real driver is loaded and doing a handoff. ... and I'm not going to ponder the depths of unload here. Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

2008-11-07*** Summary ***dyoung
When a link-layer address changes (e.g., ifconfig ex0 link 02:de:ad:be:ef:02 active), send a gratuitous ARP and/or a Neighbor Advertisement to update the network-/link-layer address bindings on our LAN peers. Refuse a change of ethernet address to the address 00:00:00:00:00:00 or to any multicast/broadcast address. (Thanks matt@.) Reorder ifnet ioctl operations so that driver ioctls may inherit the functions of their "class"---ether_ioctl(), fddi_ioctl(), et cetera---and the class ioctls may inherit from the generic ioctl, ifioctl_common(), but both driver- and class-ioctls may override the generic behavior. Make network drivers share more code. Distinguish a "factory" link-layer address from others for the purposes of both protecting that address from deletion and computing EUI64. Return consistent, appropriate error codes from network drivers. Improve readability. KNF. *** Details *** In if_attach(), always initialize the interface ioctl routine, ifnet->if_ioctl, if the driver has not already initialized it. Delete if_ioctl == NULL tests everywhere else, because it cannot happen. In the ioctl routines of network interfaces, inherit common ioctl behaviors by calling either ifioctl_common() or whichever ioctl routine is appropriate for the class of interface---e.g., ether_ioctl() for ethernets. Stop (ab)using SIOCSIFADDR and start to use SIOCINITIFADDR. In the user->kernel interface, SIOCSIFADDR's argument was an ifreq, but on the protocol->ifnet interface, SIOCSIFADDR's argument was an ifaddr. That was confusing, and it would work against me as I make it possible for a network interface to overload most ioctls. On the protocol->ifnet interface, replace SIOCSIFADDR with SIOCINITIFADDR. In ifioctl(), return EPERM if userland tries to invoke SIOCINITIFADDR. In ifioctl(), give the interface the first shot at handling most interface ioctls, and give the protocol the second shot, instead of the other way around. Finally, let compatibility code (COMPAT_OSOCK) take a shot. Pull device initialization out of switch statements under SIOCINITIFADDR. For example, pull ..._init() out of any switch statement that looks like this: switch (...->sa_family) { case ...: ..._init(); ... break; ... default: ..._init(); ... break; } Rewrite many if-else clauses that handle all permutations of IFF_UP and IFF_RUNNING to use a switch statement, switch (x & (IFF_UP|IFF_RUNNING)) { case 0: ... break; case IFF_RUNNING: ... break; case IFF_UP: ... break; case IFF_UP|IFF_RUNNING: ... break; } unifdef lots of code containing #ifdef FreeBSD, #ifdef NetBSD, and #ifdef SIOCSIFMTU, especially in fwip(4) and in ndis(4). In ipw(4), remove an if_set_sadl() call that is out of place. In nfe(4), reuse the jumbo MTU logic in ether_ioctl(). Let ethernets register a callback for setting h/w state such as promiscuous mode and the multicast filter in accord with a change in the if_flags: ether_set_ifflags_cb() registers a callback that returns ENETRESET if the caller should reset the ethernet by calling if_init(), 0 on success, != 0 on failure. Pull common code from ex(4), gem(4), nfe(4), sip(4), tlp(4), vge(4) into ether_ioctl(), and register if_flags callbacks for those drivers. Return ENOTTY instead of EINVAL for inappropriate ioctls. In zyd(4), use ENXIO instead of ENOTTY to indicate that the device is not any longer attached. Add to if_set_sadl() a boolean 'factory' argument that indicates whether a link-layer address was assigned by the factory or some other source. In a comment, recommend using the factory address for generating an EUI64, and update in6_get_hw_ifid() to prefer a factory address to any other link-layer address. Add a routing message, RTM_LLINFO_UPD, that tells protocols to update the binding of network-layer addresses to link-layer addresses. Implement this message in IPv4 and IPv6 by sending a gratuitous ARP or a neighbor advertisement, respectively. Generate RTM_LLINFO_UPD messages on a change of an interface's link-layer address. In ether_ioctl(), do not let SIOCALIFADDR set a link-layer address that is broadcast/multicast or equal to 00:00:00:00:00:00. Make ether_ioctl() call ifioctl_common() to handle ioctls that it does not understand. In gif(4), initialize if_softc and use it, instead of assuming that the gif_softc and ifp overlap. Let ifioctl_common() handle SIOCGIFADDR. Sprinkle rtcache_invariants(), which checks on DIAGNOSTIC kernels that certain invariants on a struct route are satisfied. In agr(4), rewrite agr_ioctl_filter() to be a bit more explicit about the ioctls that we do not allow on an agr(4) member interface. bzero -> memset. Delete unnecessary casts to void *. Use sockaddr_in_init() and sockaddr_in6_init(). Compare pointers with NULL instead of "testing truth". Replace some instances of (type *)0 with NULL. Change some K&R prototypes to ANSI C, and join lines.

2008-03-11Prepare for PMF self-suspension: in the if_stop() methods, cleardyoung
IFF_UP and IFF_RUNNING before running the 'disable' step, instead of after. Soon I will handle the 'disable' step by calling into PMF, which may call if_stop(, 0). Ordinarily, that is harmless. This change lets the if_stop() routines exit early when they find on entry that IFF_RUNNING is not set.
