[PATCH 0/3] Fixes for spliced connections
by Stefano Brivio 11 Oct '22

11 Oct '22

The most pressing problem fixed here is that spliced connections with a remapped destination port would be attempted on the wrong side. This is an old issue as indicated by the Fixes: tag. Patch 1/3 restores sanity in comments before we attempt to fix the issue, patch 2/3 fixes the actual issue, and patch 3/3 introduces a minor rework on top to fix another issue, where if the user explicitly configures a loopback address in a port binding we would still create a non-spliced socket stealing the … [View More]

[PATCH] netlink: Disable duplicate address detection for configured IPv6 address
by Stefano Brivio 11 Oct '22

11 Oct '22

With default options, when we pass --config-net, the IPv6 address is actually going to be recycled from the init namespace, so it is in fact duplicated, but duplicate address detection has no way to find out. With a different configured address, that's not the case, but anyway duplicate address detection will be unable to see this. In both cases, we're wasting time for nothing. Pass the IFA_F_NODAD flag as we configure globally scoped IPv6 addresses via netlink. Signed-off-by: Stefano … [View More]

[PATCH v3 0/7] Add support for log file and version display
by Stefano Brivio 11 Oct '22

11 Oct '22

Patches 1/7 to 4/7 add support for logging to a file, via -l/--log-file, with mandatory size limit and rotation. Patches 5/7 and 7/7 fix two minor details that came up while implementing the feature itself. Patch 6/7 adds a --version option with a version string generated by the Makefile using git, if available, and includes the version string in the log header. v3: - Further changes for 4/7 and 6/7 reported in change messages v2: - Drop patch adding new test from the series (8/8), … [View More]

[PATCH] udp: Fix port and address checks for DNS forwarder
by Stefano Brivio 11 Oct '22

11 Oct '22

First off, as we swap endianness for source ports in udp_fill_data_v{4,6}(), we want host endianness, not network endianness. It doesn't actually matter if we use htons() or ntohs() here, but the current version is confusing. In the IPv4 path, when we remap DNS answers, we already swapped the endianness as needed for the source port: don't swap it again, otherwise we'll not map DNS answers for IPv4. In the IPv6 path, when we remap DNS answers, we want to check that they came from our upstream … [View More]

[PATCH] packet: Fix off-by-one in packet_get_do() sanity checks
by Stefano Brivio 10 Oct '22

10 Oct '22

An n-sized pool, or a pool with n entries, doesn't include index n, only up to n - 1. I'm not entirely sure this sanity check actually covers any practical case, but I spotted this while debugging a hang in tap4_handler() (possibly due to malformed sequence entries from qemu).

[PATCH v2] conf, tcp, udp: Allow specification of interface to bind to
by Stefano Brivio 10 Oct '22

10 Oct '22

Since kernel version 5.7, commit c427bfec18f2 ("net: core: enable SO_BINDTODEVICE for non-root users"), we can bind sockets to interfaces, if they haven't been bound yet (as in bind()). Introduce an optional interface specification for forwarded ports, prefixed by %, that can be passed together with an address.

[PATCH] tap: Don't check sequence counts when adding packets to pool
by Stefano Brivio 10 Oct '22

10 Oct '22

This is a minor optimisation possibility I spotted while trying to debug a hang in tap4_handler(): if we run out of space for packet sequences, it's fine to add packets to an existing per-sequence pool. We should check the count of packet sequences only once we realise that we actually need a new packet sequence.
