[PATCH] seccomp: Fix build and operation on 32-bit musl targets
by Stefano Brivio 04 Dec '25

04 Dec '25

On 32-bit musl targets (for example, Alpine i386 / i586), we need to: - use the set of system calls already defined for i686. While Alpine's kernel supports i586 as well (Debian for example doesn't), it's the same architecture, so change i386/i486/i586 machine strings to i686 in seccomp.sh - allow clock_gettime64() as an alternative to clock_gettime() (not just added on top, rather replacing it), because clock_gettime() isn't available as a system call name at all in musl headers (while glibc aliases it to the kernel's clock_gettime64()) - similarly, allow timerfd_gettime64() as a name for timerfd_gettime() - allow timerfd_settime32() as a name for timerfd_settime(), even though there's no such system call declared in Linux kernel headers, as musl uses that name to distinguish it from timerfd_settime64() - unconditionally allow timerfd_settime64(), because musl uses it whenever the 'old' argument is non-NULL and sizeof(time_t) > 4, which happens to be the case in tcp_timer_handler() Reported-by: John D.

[PATCH v5 00/15] Reduce differences between inbound and outbound socket binding
by David Gibson 03 Dec '25

03 Dec '25

This series is based on my series fixing bug 176 (regression in auto forwarding). The fact that outbound forwarding sockets are bound to the loopback address, whereas inbound forwarding sockets are (by default) bound to the unspecified address leads to some unexpected differences between the paths setting up each of them. An idea for tackling bug 100 suggested a different approach which will also reduce some of those differences and allow more code to be shared between the two paths. I've since discovered that this approach doesn't help for bug 100, but I think it's still worthwhile for other reasons. v5: - Combine with SO_BINDTODEVICE and bug 113 patch series - Add fallback handling for kernels without SO_BINDTODEVICE - Add missing struct field documentation for no_bindtodevice v4: - Add cleanup patch removing unused structure field - Rebase, fixing conflicts with Laurent's changes - A bunch of spelling and other cosmetic fixes - Clarify relation to bug 100 and bug 113 v3: - A number of additional fixes covering the handling of IPV6_V6ONLY sockopt - Assorted trivial changes v2: - Some rearrangements and rewordings for clarity David Gibson (15): util: Correct error message on SO_BINDTODEVICE failure util: Extend sock_probe_mem() to sock_probe_features() conf: More useful errors for kernels without SO_BINDTODEVICE flow: Remove bogus @path field from flowside_sock_args inany: Let length of sockaddr_inany be implicit from the family util, flow, pif: Simplify sock_l4_sa() interface tcp: Merge tcp_ns_sock_init[46]() into tcp_sock_init_one() udp: Unify some more inbound/outbound parts of udp_sock_init() udp: Move udp_sock_init() special case to its caller util: Fix setting of IPV6_V6ONLY socket option tcp, udp: Remove fallback if creating dual stack socket fails tcp, udp: Bind outbound listening sockets by interface instead of address util: Rename sock_l4_dualstack() to sock_l4_dualstack_any() tcp: Always populate oaddr field for socket initiated flows fwd: Preserve non-standard loopback address when splice forwarding conf.c | 16 ++++- flow.c | 22 +++---- fwd.c | 4 +- icmp.c | 3 +- inany.h | 17 ++++++ passt.c | 2 +- passt.h | 2 + pif.c | 27 ++------- pif.h | 2 +- tcp.c | 162 +++++++++++++++++++++------------------------------ tcp.h | 5 +- tcp_splice.c | 5 +- udp.c | 122 +++++++++++++++++++++----------------- udp.h | 5 +- util.c | 102 +++++++++++++++++++++++++++----- util.h | 10 ++-- 16 files changed, 289 insertions(+), 217 deletions(-) -- 2.52.0

[PATCH v5 01/15] util: Correct error message on SO_BINDTODEVICE failure
by David Gibson 02 Dec '25

02 Dec '25

The warning message we print of SO_BINDTODEVICE fails is incorrect: we include EPOLL_TYPE_STR(proto), but the proto variable is not an epoll type so this will generate misleading garbage. This has been wrong ever since 340164445 but the message is rare enough that we never noticed. Correct that, and reword the message a bit for clarity while we're there.

[PATCH 0/3] More graceful handling of kernels without SO_BINDTODEVICE
by David Gibson 28 Nov '25

28 Nov '25

Kernels before v5.7 don't allow unprivileged processes to use the SO_BINDTODEVICE socket option, which is how we implement per-device listening (e.g. "-t ""%eth0/80"). Currently we detect this error quite late, and don't produce a particularly helpful error message. Improve error messages in this case by explicitly probing for support of the option early. More importantly this will allow me to implement fallback handling for older kernels in upcoming socket binding cleanups. Note: this series applies directly on the current main branch, I'm going to rebase my socket binding series on top of this, instead of the other way around.

[PATCH v2 0/6] vhost-user: Add multiqueue support
by Laurent Vivier 28 Nov '25

28 Nov '25

This series implements multiqueue support for vhost-user mode, allowing passt to utilize multiple queue pairs. There is no improved network performance because we keep using only one thread. The implementation introduces a --max-queues parameter to configure up to 16 queue pairs (32 virtqueues) in vhost-user mode. Packets are routed to the appropriate RX queue based on which TX queue they originated from, enabling the guest kernel to distribute network traffic across multiple queues and vCPUs. This series adds: - configuration support for multiqueue via --max-queues parameter - one packet pool per queue pair instead of shared pools - queue parameter threading throughout the network stack - a significant refactoring that propagates queue information through all protocol handlers (TCP, UDP, ICMP, ARP, DHCP, DHCPv6, NDP) - flow-aware queue routing that matches RX queue selection to the incoming TX queue, maintaining proper packet affinity - test coverage with VHOST_USER_MQ environment variable to validate multiqueue functionality across all protocols (TCP, UDP, ICMP) and services (DHCP, NDP) Current behavior: TX queue selection is controlled by the guest kernel, while RX packets are routed to queues based on their associated flows. Host-initiated flows currently default to queue 0. The RX queue of a flow is updated on each new packet from the TX queue to maintain affinity. The changes maintain backward compatibility - without --max-queues, behavior remains unchanged with single-queue operation. v2: - New patch: "tap: Remove pool parameter from tap4_handler() and tap6_handler()" to clean up unused parameters before adding queue pair parameter - Changed to one packet pool per queue pair instead of shared pools across all queue pairs - Split "multiqueue: Add queue-aware flow management..." into two patches: - "tap: Add queue pair parameter throughout the packet processing path" - "flow: Add queue pair tracking to flow management" - Updated test infrastructure patch with refined implementation Laurent Vivier (6): tap: Remove pool parameter from tap4_handler() and tap6_handler() vhost-user: Enable multiqueue vhost-user: Add queue pair parameter throughout the network stack tap: Add queue pair parameter throughout the packet processing path flow: Add queue pair tracking to flow management test: Add multiqueue support to vhost-user test infrastructure arp.c | 12 ++-- arp.h | 4 +- conf.c | 31 ++++++++- dhcp.c | 5 +- dhcp.h | 2 +- dhcpv6.c | 12 ++-- dhcpv6.h | 2 +- flow.c | 30 +++++++++ flow.h | 17 +++++ fwd.c | 4 +- icmp.c | 25 ++++--- icmp.h | 2 +- ndp.c | 32 +++++---- ndp.h | 5 +- passt.h | 2 + tap.c | 173 +++++++++++++++++++++++++++++-------------------- tap.h | 20 +++--- tcp.c | 66 +++++++++++-------- tcp.h | 11 ++-- tcp_vu.c | 8 ++- test/lib/setup | 58 +++++++++++++---- test/run | 23 +++++++ udp.c | 39 ++++++----- udp.h | 12 ++-- udp_flow.c | 8 ++- udp_flow.h | 2 +- udp_vu.c | 4 +- vhost_user.c | 38 ++++++----- virtio.h | 2 +- vu_common.c | 15 +++-- vu_common.h | 3 +- 31 files changed, 443 insertions(+), 224 deletions(-) -- 2.51.0

[PATCH] arp/ndp: don't send messages on uninitialized tap interface
by Jon Maloy 27 Nov '25

27 Nov '25

When running pasta without --config-net, the tap interface is opened and assigned a valid file descriptor, but intentionally not brought up in the namespace. This is the expected behavior when the user wants to configure the namespace manually. However, in PASTA mode the code is attempting to send ARP announcements and NDP messages (initial requests and unsolicited NAs) based solely on whether c->fd_tap is valid, without checking if the interface actually is up and ready to transmit. This results in send failures, and when debug is activated (pasta -d) we see error printouts for these early messages. We now add new function tap_is_ready() which checks both conditions: - Whether fd_tap is valid (all modes) - Whether the tap interface is up (pasta mode only). In this mode, we use the existing c->pasta_conf_ns flag, which indicates whether pasta_ns_conf() configured and brought up the interface. This test is simple, and good enough for now. We update all functions that send unsolicited ARP/NDP messages to check with the new function before making any send attempt. This eliminates spurious send errors when starting pasta without --config-net, while preserving correct behavior when the interface is properly initialized.

[PATCH] test: Fix IPv6 address/prefix mismatch error
by Yumei Huang 27 Nov '25

27 Nov '25

For IPv6 addresses within the same scope group, Linux kernel preserves insertion order, where the first inserted address appears last. As a result, the ordering inside pasta differs from the host, causing a few tests to fail when they compare only the first address on each side. Fix this by checking that the guest’s first address matches any of the host’s addresses.
