set .destroy callback releases the references to other objects in maps. This is very late and it results in spurious EBUSY errors. Drop refcount from the preparation phase instead, update set backend not to drop reference counter from set .destroy path. Exceptions: NFT_TRANS_PREPARE_ERROR does not require to drop the reference counter because the transaction abort path releases the map references for each element since the set is unbound. The abort path also deals with releasing reference counter for new elements added to unbound sets.

Add a new state to deal with rule expressions deactivation from the newrule error path, otherwise the anonymous set remains in the list in inactive state for the next generation. Mark the set/chain transaction as unbound so the abort path releases this object, set it as inactive in the next generation so it is not reachable anymore from this transaction and reference counter is dropped.

Add bound flag to rule and chain transactions as in 6a0a8d10 ("netfilter: nf_tables: use-after-free in failing rule with bound set") to skip them in case that the chain is already bound from the abort path. This patch fixes an imbalance in the chain use refcnt that triggers a WARN_ON on the table and chain destroy path. This patch also disallows nested chain bindings, which is not supported from userspace. The logic to deal with chain binding in nft_data_hold() and nft_data_release() is not correct. The NFT_TRANS_PREPARE state needs a special handling in case a chain is bound but next expressions in the same rule fail to initialize as described by 1240eb93 ("netfilter: nf_tables: incorrect error path handling with NFT_MSG_NEWRULE"). The chain is left bound if rule construction fails, so the objects stored in this chain (and the chain itself) are released by the transaction records from the abort path, follow up patch ("netfilter: nf_tables: add NFT_TRANS_PREPARE_ERROR to deal with bound set/chain") completes this error handling. When deleting an existing rule, chain bound flag is set off so the rule expression .destroy path releases the objects. Fixes: d0e2c7de ("netfilter: nf_tables: add NFT_CHAIN_BINDING") Signed-off-by:

When using encapsulation the original packet's headers are copied to the inner headers. This preserves the space for an inner mac header, which is not used by the inner payloads for the encapsulation types supported by IPVS. If a packet is using GUE or GRE encapsulation and needs to be segmented, flow can be passed to __skb_udp_tunnel_segment() which calculates a negative tunnel header length. A negative tunnel header length causes pskb_may_pull() to fail, dropping the packet. This can be observed by attaching probes to ip_vs_in_hook(), __dev_queue_xmit(), and __skb_udp_tunnel_segment(): perf probe --add '__dev_queue_xmit skb->inner_mac_header \ skb->inner_network_header skb->mac_header skb->network_header' perf probe --add '__skb_udp_tunnel_segment:7 tnl_hlen' perf probe -m ip_vs --add 'ip_vs_in_hook skb->inner_mac_header \ skb->inner_network_header skb->mac_header skb->network_header' These probes the headers and tunnel header length for packets which traverse the IPVS encapsulation path. A TCP packet can be forced into the segmentation path by being smaller than a calculated clamped MSS, but larger than the advertised MSS. probe:ip_vs_in_hook: inner_mac_header=0x0 inner_network_header=0x0 mac_header=0x44 network_header=0x52 probe:ip_vs_in_hook: inner_mac_header=0x44 inner_network_header=0x52 mac_header=0x44 network_header=0x32 probe:dev_queue_xmit: inner_mac_header=0x44 inner_network_header=0x52 mac_header=0x44 network_header=0x32 probe:__skb_udp_tunnel_segment_L7: tnl_hlen=-2 When using veth-based encapsulation, the interfaces are set to be mac-less, which does not preserve space for an inner mac header. This prevents this issue from occurring. In our real-world testing of sending a 32KB file we observed operation time increasing from ~75ms for veth-based encapsulation to over 1.5s using IPVS encapsulation due to retries from dropped packets. This changeset modifies the packet on the encapsulation path in ip_vs_tunnel_xmit() and ip_vs_tunnel_xmit_v6() to remove the inner mac header offset. This fixes UDP segmentation for both encapsulation types, and corrects the inner headers for any IPIP flows that may use it.

In case the QCA7000 is not available via SPI (e.g. in reset), the driver will cause a high load. The reason for this is that the synchronization is never finished and schedule() is never called. Since the synchronization is not timing critical, it's safe to drop this from the scheduling condition. Signed-off-by:

If the core is left to remove the LEDs via devm_, it is performed too late, after the PHY driver is removed from the PHY. This results in dereferencing a NULL pointer when the LED core tries to turn the LED off before destroying the LED. Manually unregister the LEDs at a safe point in phy_remove.

When running workloads heavy unbalanced towards TX (high TX, low RX traffic), sfc driver can retain the CPU during too long times. Although in many cases this is not enough to be visible, it can affect performance and system responsiveness. A way to reproduce it is to use a debug kernel and run some parallel netperf TX tests. In some systems, this will lead to this message being logged: kernel:watchdog: BUG: soft lockup - CPU#12 stuck for 22s! The reason is that sfc driver doesn't account any NAPI budget for the TX completion events work. With high-TX/low-RX traffic, this makes that the CPU is held for long time for NAPI poll. Documentations says "drivers can process completions for any number of Tx packets but should only process up to budget number of Rx packets". However, many drivers do limit the amount of TX completions that they process in a single NAPI poll. In the same way, this patch adds a limit for the TX work in sfc. With the patch applied, the watchdog warning never appears. Tested with netperf in different combinations: single process / parallel processes, TCP / UDP and different sizes of UDP messages. Repeated the tests before and after the patch, without any noticeable difference in network or CPU performance.

XFRM core provides two callbacks to release resources, one is .xdo_dev_policy_delete() and another is .xdo_dev_policy_free(). This separation allows delayed release so "ip xfrm policy free" commands won't starve.

The kernel IRQ system needs the irq affinity notifier to be clear before attempting to free the irq, see WARN_ON log below. On a normal driver unload we don't have this issue since we do the complete cleanup of the irq resources.

Magali Lemes says: ==================== Check if FIPS mode is enabled when running selftests Some test cases from net/tls, net/fcnal-test and net/vrf-xfrm-tests that rely on cryptographic functions to work and use non-compliant FIPS algorithms fail in FIPS mode. In order to allow these tests to pass in a wider set of kernels, - for net/tls, skip the test variants that use the ChaCha20-Poly1305 and SM4 algorithms, when FIPS mode is enabled; - for net/fcnal-test, skip the MD5 tests, when FIPS mode is enabled; - for net/vrf-xfrm-tests, replace the algorithms that are not FIPS-compliant with compliant ones. v1: https://lore.kernel.org/netdev/20230607174302.19542-1-magali.lemes@canonical.com/ v2: https://lore.kernel.org/netdev/20230609164324.497813-1-magali.lemes@canonical.com/ v3: https://lore.kernel.org/netdev/20230612125107.73795-1-magali.lemes@canonical.com/ ==================== Link: https://lore.kernel.org/r/20230613123222.631897-1-magali.lemes@canonical.comSigned-off-by:

There are some MD5 tests which fail when the kernel is in FIPS mode, since MD5 is not FIPS compliant. Add a check and only run those tests if FIPS mode is not enabled. Fixes: f0bee1eb ("fcnal-test: Add TCP MD5 tests") Fixes: 5cad8bce ("fcnal-test: Add TCP MD5 tests for VRF") Reviewed-by:

The vrf-xfrm-tests tests use the hmac(md5) and cbc(des3_ede) algorithms for performing authentication and encryption, respectively. This causes the tests to fail when fips=1 is set, since these algorithms are not allowed in FIPS mode. Therefore, switch from hmac(md5) and cbc(des3_ede) to hmac(sha1) and cbc(aes), which are FIPS compliant. Fixes: 3f251d74 ("selftests: Add tests for vrf and xfrms") Reviewed-by:

TLS selftests use the ChaCha20-Poly1305 and SM4 algorithms, which are not FIPS compliant. When fips=1, this set of tests fails. Add a check and only run these tests if not in FIPS mode.

Before executing each test from a fixture, FIXTURE_SETUP is run once. When SKIP is used in FIXTURE_SETUP, the setup function returns early but the test still proceeds to run, unless another SKIP macro is used within the test definition, leading to some code repetition. Therefore, allow tests to be skipped directly from the setup function. Suggested-by:

Pull networking fixes from Jakub Kicinski: "Including fixes from wireless, and netfilter. Selftests excluded - we have 58 patches and diff of +442/-199, which isn't really small but perhaps with the exception of the WiFi locking change it's old(ish) bugs. We have no known problems with v6.4. The selftest changes are rather large as MPTCP folks try to apply Greg's guidance that selftest from torvalds/linux should be able to run against stable kernels. Last thing I should call out is the DCCP/UDP-lite deprecation notices. We are fairly sure those are dead, but if we're wrong reverting them back in won't be fun.

DCCP was marked as Orphan in the MAINTAINERS entry 2 years ago in commit 054c4610 ("MAINTAINERS: dccp: move Gerrit Renker to CREDITS"). It says we haven't heard from the maintainer for five years, so DCCP is not well maintained for 7 years now. Recently DCCP only receives updates for bugs, and major distros disable it by default. Removing DCCP would allow for better organisation of TCP fields to reduce the number of cache lines hit in the fast path. Let's add a deprecation notice when DCCP socket is created and schedule its removal to 2025. Signed-off-by:

Recently syzkaller reported a 7-year-old null-ptr-deref [0] that occurs when a UDP-Lite socket tries to allocate a buffer under memory pressure. Someone should have stumbled on the bug much earlier if UDP-Lite had been used in a real app. Also, we do not always need a large UDP-Lite workload to hit the bug since UDP and UDP-Lite share the same memory accounting limit. Removing UDP-Lite would simplify UDP code removing a bunch of conditionals in fast path. Let's add a deprecation notice when UDP-Lite socket is created and schedule its removal to 2025.
