Until recently, the ovs-dpctl utility was used with a limited actions set and didn't need to have support for multiple similar actions. However, when adding support for tunnels, it will be important to support multiple set() actions in a single flow. When printing these actions, the existing code will be unable to print all of the sets - it will only print the first. Refactor this code to be easier to read and support multiple actions of the same type in an action list. Reviewed-by:

The OVS module can operate in conjunction with various types of tunnel ports. These are created as either explicit tunnel vport types, OR by creating a tunnel interface which acts as an anchor for the lightweight tunnel support. This patch adds the ability to add tunnel ports to an OVS datapath for testing various scenarios with tunnel ports. With this addition, the vswitch "plumbing" will at least be able to push packets around using the tunnel vports. Future patches will add support for setting required tunnel metadata for lwts in the datapath. The end goal will be to push packets via these tunnels, and will be used in an upcoming commit for testing the path MTU. Reviewed-by:

Patch #2 fixes a possible pointer leak to userspace due to insufficient validation of NFT_DATA_VALUE. Linus found this pointer leak to userspace via zdi-disclosures@ and forwarded the notice to Netfilter maintainers, he appears as reporter because whoever found this issue never approached Netfilter maintainers neither via security@ nor in private. netfilter pull request 24-06-27 * tag 'nf-24-06-27' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf: netfilter: nf_tables: fully validate NFT_DATA_VALUE on store to data registers netfilter: fix undefined reference to 'netfilter_lwtunnel_*' when CONFIG_SYSCTL=n ==================== Link: https://patch.msgid.link/20240626233845.151197-1-pablo@netfilter.orgSigned-off-by:

When SO_OOBINLINE is enabled on a socket, MSG_OOB can be recv()ed without MSG_OOB flag, and ioctl(SIOCATMARK) will behaves differently. This patch adds some test cases for SO_OOBINLINE. Note the new test cases found two bugs in TCP. 1) After reading OOB data with non-inline mode, we can re-read the data by setting SO_OOBINLINE. # RUN msg_oob.no_peek.inline_oob_ahead_break ... # msg_oob.c:146:inline_oob_ahead_break:AF_UNIX :world # msg_oob.c:147:inline_oob_ahead_break:TCP :oworld # OK msg_oob.no_peek.inline_oob_ahead_break ok 14 msg_oob.no_peek.inline_oob_ahead_break 2) The head OOB data is dropped if SO_OOBINLINE is disabled if a new OOB data is queued. # RUN msg_oob.no_peek.inline_ex_oob_drop ... # msg_oob.c:171:inline_ex_oob_drop:AF_UNIX :x # msg_oob.c:172:inline_ex_oob_drop:TCP :y # msg_oob.c:146:inline_ex_oob_drop:AF_UNIX :y # msg_oob.c:147:inline_ex_oob_drop:TCP :Resource temporarily unavailable # OK msg_oob.no_peek.inline_ex_oob_drop ok 17 msg_oob.no_peek.inline_ex_oob_drop Signed-off-by: -

While testing, I found some weird behaviour on the TCP side as well. For example, TCP drops the preceding OOB data when queueing a new OOB data if the old OOB data is at the head of recvq. # RUN msg_oob.no_peek.ex_oob_drop ... # msg_oob.c:146:ex_oob_drop:AF_UNIX :x # msg_oob.c:147:ex_oob_drop:TCP :Resource temporarily unavailable # msg_oob.c:146:ex_oob_drop:AF_UNIX :y # msg_oob.c:147:ex_oob_drop:TCP :Invalid argument # OK msg_oob.no_peek.ex_oob_drop ok 9 msg_oob.no_peek.ex_oob_drop # RUN msg_oob.no_peek.ex_oob_drop_2 ... # msg_oob.c:146:ex_oob_drop_2:AF_UNIX :x # msg_oob.c:147:ex_oob_drop_2:TCP :Resource temporarily unavailable # OK msg_oob.no_peek.ex_oob_drop_2 ok 10 msg_oob.no_peek.ex_oob_drop_2 This patch allows AF_UNIX's MSG_OOB implementation to produce different results from TCP when operations are guarded with tcp_incompliant{}.

Let's say a socket send()s "hello" with MSG_OOB and "world" without flags, >>> from socket import * >>> c1, c2 = socketpair(AF_UNIX) >>> c1.send(b'hello', MSG_OOB) 5 >>> c1.send(b'world') 5 and its peer recv()s "hell" and "o". >>> c2.recv(10) b'hell' >>> c2.recv(1, MSG_OOB) b'o' Now the consumed OOB skb stays at the head of recvq to return a correct value for ioctl(SIOCATMARK), which is broken now and fixed by a later patch. Then, if peer issues recv() with MSG_DONTWAIT, manage_oob() returns NULL, so recv() ends up with -EAGAIN. >>> c2.setblocking(False) # This causes -EAGAIN even with available data >>> c2.recv(5) Traceback (most recent call last): File "<stdin>", line 1, in <module> BlockingIOError: [Errno 11] Resource temporarily unavailable However, next recv() will return the following available data, "world". >>> c2.recv(5) b'world' When the consumed OOB skb is at the head of the queue, we need to fetch the next skb to fix the weird behaviour. Note that the issue does not happen without MSG_DONTWAIT because we can retry after manage_oob(). This patch also adds a test case that covers the issue.

After consuming OOB data, recv() reading the preceding data must break at the OOB skb regardless of MSG_PEEK. Currently, MSG_PEEK does not stop recv() for AF_UNIX, and the behaviour is not compliant with TCP. >>> from socket import * >>> c1, c2 = socketpair(AF_UNIX) >>> c1.send(b'hello', MSG_OOB) 5 >>> c1.send(b'world') 5 >>> c2.recv(1, MSG_OOB) b'o' >>> c2.recv(9, MSG_PEEK) # This should return b'hell' b'hellworld' # even with enough buffer. Let's fix it by returning NULL for consumed skb and unlinking it only if MSG_PEEK is not specified. This patch also adds test cases that add recv(MSG_PEEK) before each recv().

AF_UNIX's MSG_OOB functionality lacked thorough testing, and we found some bizarre behaviour. The new selftest validates every MSG_OOB operation against TCP as a reference implementation. This patch adds only a few tests with basic send() and recv() that do not fail. The following patches will add more test cases for SO_OOBINLINE, SIGURG, EPOLLPRI, and SIOCATMARK. Signed-off-by:

test_unix_oob.c does not fully cover AF_UNIX's MSG_OOB functionality, thus there are discrepancies between TCP behaviour. Also, the test uses fork() to create message producer, and it's not easy to understand and add more test cases. Let's remove test_unix_oob.c and rewrite a new test. Signed-off-by:

In the TRACE_EVENT(qdisc_reset) NULL dereference occurred from qdisc->dev_queue->dev <NULL> ->name This situation simulated from bunch of veths and Bluetooth disconnection and reconnection. During qdisc initialization, qdisc was being set to noop_queue. In veth_init_queue, the initial tx_num was reduced back to one, causing the qdisc reset to be called with noop, which led to the kernel panic. I've attached the GitHub gist link that C converted syz-execprogram source code and 3 log of reproduced vmcore-dmesg. https://gist.github.com/yskelg/cc64562873ce249cdd0d5a358b77d740 Yeoreum and I use two fuzzing tool simultaneously. One process with syz-executor : https://github.com/google/syzkaller $ ./syz-execprog -executor=./syz-executor -repeat=1 -sandbox=setuid \ -enable=none -collide=false log1 The other process with perf fuzzer: https://github.com/deater/perf_event_tests/tree/master/fuzzer $ perf_event_tests/fuzzer/perf_fuzzer I think this will happen on the kernel version. Linux kernel version +v6.7.10, +v6.8, +v6.9 and it could happen in v6.10. This occurred from 51270d57. I think this patch is absolutely necessary.

register store validation for NFT_DATA_VALUE is conditional, however, the datatype is always either NFT_DATA_VALUE or NFT_DATA_VERDICT. This only requires a new helper function to infer the register type from the set datatype so this conditional check can be removed. Otherwise, pointer to chain object can be leaked through the registers. Fixes: 96518518 ("netfilter: add nftables") Reported-by:

Merge tag 'asoc-fix-v6.10-rc5' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v6.10 A relatively large batch of updates, largely due to the long interval since I last sent fixes due to various travel and holidays. There's a lot of driver specific fixes and quirks in here, none of them too major, and also some fixes for recently introduced memory safety issues in the topology code.

The currently existing of_property_present check for interrupts does not cover all ways interrupts can be defined in a device tree, e.g. "interrupts-extended". In order to support all current and future ways that can be done, drop that check and call of_irq_parse_one to figure out if an interrupt is defined and irq_create_of_mapping for the actual mapping and let it be handled by the interrupt subsystem.

After being asked about support for WPA3 for BCM43224 chipset it was found that all it takes is setting the MFP_CAPABLE flag and mac80211 will take care of all that is needed [1]. Link: https://lore.kernel.org/linux-wireless/20200526155909.5807-2-Larry.Finger@lwfinger.net/ [1] Signed-off-by:

ath.git tree has moved to a new location. The old location will be an alias to the new location and will work at least until end of 2024, but best to update git trees already now. Signed-off-by:

We got sad news that Larry is not with us anymore. He was a long time Linux developer, his first commit was back in 2005 and he has maintained several wireless drivers over the years. He was known for patiently supporting Linux users with all sorts of problems they had. Larry's work helped so many people around the world and I always enjoyed working with him, even though I sadly never met him. Rest in Peace, Larry. You will be missed.
