* pkg/mgrconfig, prog, sys/linux: add automatic_helper attributePimyn Girgis2024-09-091-2/+2
| | | | | Add automatic_helper attribute and enable it for system calls that are required to properly run automatically generated descriptions. Enable these system calls when descriptions_mode = `Auto`.
* sys/linux: use nested flag definitions where sensiblePaul Chaignon2023-12-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All flags that are subset of other flags were identified with the following Bash script [1]. Only a small set of flags identified by the script were rewritten to use nested flag definitions, after manually checking if it makes sense (based on syzkaller context and man pages). For example, msgget_flags was rewritten as follows: -msgget_flags = IPC_CREAT, IPC_EXCL, S_IRUSR, S_IWUSR, S_IXUSR, S_IRGRP, S_IWGRP, S_IXGRP, S_IROTH, S_IWOTH, S_IXOTH +msgget_flags = IPC_CREAT, IPC_EXCL, open_mode According to the msgget(2) man page: Upon creation, the least significant bits of the argument msgflg define the permissions of the message queue. These permission bits have the same format and semantics as the permissions specified for the mode argument of open(2). So it is correct to use open_mode directly in the definition of the flags for msgget(2). 1 - #!/bin/bash regexp_flags="^(\w+)\s*=\s+([a-zA-Z\"][^=]*)$" is_subset() { local -n subset=$1 local -n superset=$2 for element in "${subset[@]}"; do if [[ !

* sys/linux: remove references to DECnetHrutvik Kanabar2022-10-271-2/+2
| | | | | This was removed from the upstream kernel in: torvalds/linux@1202cdd665315c525b5237e96e0bedc76d7e754f
* executor: add NIC PCI pass-through VF supportGeorge Kennedy2022-09-211-1/+1
| | | | | | | | | | | | | | | Add support for moving a NIC PCI pass-through VF into Syzkaller's network namespace so that it will tested. As DEVLINK support is triggered by setting the pass-through device to "addr=0x10", NIC PCI pass-through VF support will be triggered by setting the device to "addr=0x11". If a NIC PCI pass-through VF is detected in do_sandbox, setup a staging namespace before the fork() and transfer the NIC VF interface to it. After the fork() and in the child transfer the NIC VF interface to Syzkaller's network namespace and rename the interface to netpci0 so that it will be tested.

* sys/linux: add IGMP (SOCK_RAW/IPPROTO_IGMP) descriptionsDmitry Vyukov2022-06-141-1/+1
| | | | | | Add descriptions for: https://elixir.bootlin.com/linux/v5.19-rc1/source/include/uapi/linux/mroute.h https://elixir.bootlin.com/linux/v5.19-rc1/source/include/uapi/linux/mroute6.h
* sys/linux: don't use len/flags/const/proc types in out fieldsDmitry Vyukov2022-01-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Remove all uses of len/flags/const/proc types in explicitly marked out fields. Use of these types for out fields does not make sense: a len[b, int32] (out) b flags[foo, int32] (out) Since kernel fills these fields, that's unnecessary details or bugs in descriptions. In particular all of these are actually bugs: ioctl$TUNSETQUEUE(fd fd_tun, cmd const[TUNSETQUEUE], arg ptr[in, ifreq_t[flags[tun_queue_flags, int16]]]) ioctl$TUNSETIFF(fd fd_tun, cmd const[TUNSETIFF], arg ptr[in, ifreq_t[flags[tun_setiff_flags, int16]]]) ioctl$SIOCSIFHWADDR(fd fd_tun, cmd const[SIOCSIFHWADDR], arg ptr[in, ifreq_t[mac_addr]]) ioctl$sock_inet_SIOCSIFADDR(fd sock, cmd const[SIOCSIFADDR], arg ptr[inout, ifreq_t[sockaddr_in]]) ioctl$sock_inet_SIOCSIFBRDADDR(fd sock, cmd const[SIOCSIFBRDADDR], arg ptr[inout, ifreq_t[sockaddr_in]]) ioctl$sock_inet_SIOCSIFNETMASK(fd sock, cmd const[SIOCSIFNETMASK], arg ptr[inout, ifreq_t[sockaddr_in]]) ioctl$sock_inet_SIOCSIFDSTADDR(fd sock, cmd const[SIOCSIFDSTADDR], arg ptr[inout, ifreq_t[sockaddr_in]]) ioctl$sock_inet_SIOCSIFPFLAGS(fd sock, cmd const[SIOCSIFPFLAGS], arg ptr[inout, ifreq_t[int32]]) ioctl$SIOCSIFMTU(fd sock_pppl2tp, cmd const[SIOCSIFMTU], arg ptr[in, ifreq_t[int32]]) ioctl$sock_SIOCETHTOOL(fd sock, cmd const[SIOCETHTOOL], arg ptr[inout, ifreq_t[ptr[inout, ethtool_cmd_u]]]) We pretend that we pass in some flags or addresses, but the ifreq field was marked as (out), so we actually did not pass anything in.
* sys/linux: regenerate consts, remove ipxDmitry Vyukov2021-10-131-4/+2
| | | | | | Regenerate const files on the latest upstream tree. Remove IPX support since it was removed from the kernel in 7a2e838d28 ("staging: ipx: delete it from the tree").
* sys/linux: add ieee802154 descriptionsDmitry Vyukov2021-02-121-1/+2

* sys/linux: enhance ifreq_dev_t definition by setting attribute directionsAleksandr Nogikh2020-09-221-3/+3
| | | | | This modification allows to remove [opt] modified for all uses of ifreq_dev_t and ifreq_t
* all: integrate with mac80211_hwsimAleksandr Nogikh2020-09-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two virtual wireless devices are instantiated during network devices initialization. A new flag (-wifi) is added that controls whether these virtual wifi devices are instantiated and configured during proc initialization. Also, two new pseudo syscalls are added: 1. syz_80211_inject_frame(mac_addr, packet, packet_len) -- injects an arbitrary packet into the wireless stack. It is injected as if it originated from the device identitied by mac_addr. 2. syz_80211_join_ibss(interface_name, ssid, ssid_len, mode) -- puts a specific network interface into IBSS state and joins an IBSS network. Arguments of syz_80211_join_ibss: 1) interface_name -- null-terminated string that identifies a wireless interface 2) ssid, ssid_len -- SSID of an IBSS network to join to 3) mode -- mode of syz_80211_join_ibss operation (see below) Modes of operation: JOIN_IBSS_NO_SCAN (0x0) -- channel scan is not performed and syz_80211_join_ibss waits until the interface reaches IF_OPER_UP. JOIN_IBSS_BG_SCAN (0x1) -- channel scan is performed (takes ~ 9 seconds), syz_80211_join_ibss does not await IF_OPER_UP. JOIN_IBSS_BG_NO_SCAN (0x2) -- channel scan is not performed, syz_80211_join_ibss does not await IF_OPER_UP. Local testing ensured that these syscalls are indeed able to set up an operating network and inject packets into mac80211.
* sys/linux: add descriptions for qrtr socketNecip Fazil Yildiran2020-06-231-2/+4
| | | | | Added descriptions to test Qualcomm's IPC router protocol for sockets. Update #533.
* pkg/compiler: refactor attribute handlingDmitry Vyukov2020-04-191-2/+2
| | | | | | | | | | | | Introduce common infrastructure for describing and parsing attribute instead of custom per-attribute code scattered across several locations. Change align attribute syntax from the weird align_N to align[N]. This also allows to use literal constants as N. Introduce notion of builtin constants. Currently we have only PTR_SIZE, which is needed to replace align_ptr with align[PTR_SIZE].
* pkg/compiler: check that const values fit into base typeDmitry Vyukov2020-03-171-2/+2
| | | | | const[0x12345678, int8] is always an error, detect these cases. Found some bugs in mptcp, socket proto and fuchsia fidl descriptions.
* pkg/compiler: ensure consistency of syscall argument typesDmitry Vyukov2020-03-171-2/+2
| | | | | | | | | | | | | | | | | | Ensure that we don't have conflicting sizes for the same argument of the same syscall, e.g.: foo$1(a int16) foo$2(a int32) This is useful for several reasons: - we will be able avoid morphing syscalls into other syscalls - we will be able to figure out more precise sizes for args (lots of them are implicitly intptr, which is the largest type on most important arches) - found few bugs in linux descriptions Update #477 Update #502
* wireguard: use wg0, wg1, wg2Jason A. Donenfeld2020-02-101-1/+1
| | | | | This matches more closely what people are used to dealing with. We also add one additional device for interesting multi-interface effects.

* sys/linux: fix SIOCGIFINDEXDmitry Vyukov2020-01-031-1/+1
| | | | | | | Mark ifindex as opt in SIOCGIFINDEX. Otherwise it's considered inout and SIOCGIFINDEX can't be used to produce ifindex'es on its own. It requires an input ifindex first and only then it can output own ifindex.
* executor: connect virt_wifi to vethDmitry Vyukov2020-01-031-1/+1
| | | | | | virt_wifi docs say that the enslaved device won't be usable on itself. It's probably not a good idea to make lo unusable. Enslave a dedicated veth instead.
