2024-05-10netfilter: nf_tables: allow clone callbacks to sleepFlorian Westphal
Sven Auhagen reports transaction failures with following error: ./main.nft:13:1-26: Error: Could not process rule: Cannot allocate memory percpu: allocation failed, size=16 align=8 atomic=1, atomic alloc failed, no space left This points to failing pcpu allocation with GFP_ATOMIC flag. However, transactions happen from user context and are allowed to sleep. One case where we can call into percpu allocator with GFP_ATOMIC is nft_counter expression. Normally this happens from control plane, so this could use GFP_KERNEL instead. But one use case, element insertion from packet path, needs to use GFP_ATOMIC allocations (nft_dynset expression). At this time, .clone callbacks always use GFP_ATOMIC for this reason. Add gfp_t argument to the .clone function and pass GFP_KERNEL or GFP_ATOMIC flag depending on context, this allows all clone memory allocations to sleep for the normal (transaction) case.

2024-05-10selftests: netfilter: add packetdrill based conntrack testsFlorian Westphal
Add a new test script that uses packetdrill tool to exercise conntrack state machine. Needs ip/ip6tables and conntrack tool (to check if we have an entry in the expected state). Test cases added here cover following scenarios: 1. already-acked (retransmitted) packets are not tagged as INVALID 2. RST packet coming when conntrack is already closing (FIN/CLOSE_WAIT) transitions conntrack to CLOSE even if the RST is not an exact match 3. RST packets with out-of-window sequence numbers are marked as INVALID 4. SYN+Challenge ACK: check that challenge ack is allowed to pass 5. Old SYN/ACK: check conntrack handles the case where SYN is answered with SYN/ACK for an old, previous connection attempt 6. Check SYN reception while in ESTABLISHED state generates a challenge ack, RST response clears 'outdated' state + next SYN retransmit gets us into 'SYN_RECV' conntrack state. Tests get run twice, once with ipv4 and once with ipv6. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2024-05-10netfilter: nft_set_pipapo: move cloning of match info to insert/removal pathFlorian Westphal
This set type keeps two copies of the sets' content, priv->match (live version, used to match from packet path) priv->clone (work-in-progress version of the 'future' priv->match). All additions and removals are done on priv->clone. When transaction completes, priv->clone becomes priv->match and a new clone is allocated for use by next transaction. Problem is that the cloning requires GFP_KERNEL allocations but we cannot fail at either commit or abort time. This patch defers the clone until we get an insertion or removal request. This allows us to handle OOM situations correctly. This also allows to remove ->dirty in a followup change: If ->clone exists, ->dirty is always true If ->clone is NULL, ->dirty is always false, no elements were added or removed (except catchall elements which are external to the specific set backend).

2024-05-10net: ipv6: fix wrong start position when receive hop-by-hop fragmentgaoxingwang
In IPv6, ipv6_rcv_core will parse the hop-by-hop type extension header and increase skb->transport_header by one extension header length. But if there are more other extension headers like fragment header at this time, the skb->transport_header points to the second extension header, not the transport layer header or the first extension header. This will result in the start and nexthdrp variable not pointing to the same position in ipv6frag_thdr_trunced, and ipv6_skip_exthdr returning incorrect offset and frag_off.Sometimes,the length of the last sharded packet is smaller than the calculated incorrect offset, resulting in packet loss. We can use network header to offset and calculate the correct position to solve this problem.

2024-05-10clocksource/drivers/renesas-ostm: Avoid reprobe after successful early probeGeert Uytterhoeven
The Renesas OS Timer (OSTM) driver contains two probe points, of which only one should complete: 1. Early probe, using TIMER_OF_DECLARE(), to provide the sole clocksource on (arm32) RZ/A1 and RZ/A2 SoCs, 2. Normal probe, using a platform driver, to provide additional timers on (arm64 + riscv) RZ/G2L and similar SoCs. The latter is needed because using OSTM on RZ/G2L requires manipulation of its reset signal, which is not yet available at the time of early probe, causing early probe to fail with -EPROBE_DEFER. It is only enabled when building a kernel with support for the RZ/G2L family, so it does not impact RZ/A1 and RZ/A2. Hence only one probe method can complete on all affected systems. As relying on the order of initialization of subsystems inside the kernel is fragile, set the DT node's OF_POPULATED flag after a succesful early probe. This makes sure the platform driver's probe is never called after a successful early probe.

2024-05-10clocksource/drivers/renesas-ostm: Allow OSTM driver to reprobe for RZ/V2H(P) SoCLad Prabhakar
The RZ/V2H(P) (R9A09G057) SoC is equipped with the Generic Timer Module, also known as OSTM. Similar to the RZ/G2L SoC, the OSTM on the RZ/V2H(P) SoC requires the reset line to be deasserted before accessing any registers. Early call to ostm_init() happens through TIMER_OF_DECLARE() which always fails with -EPROBE_DEFER, as resets are not available that early in the boot process. To address this issue on the RZ/V2H(P) SoC, enable the OSTM driver to be reprobed through the platform driver probe mechanism.

2024-05-10afs: Fix fileserver rotation getting stuckDavid Howells
Fix the fileserver rotation code in a couple of ways: (1) op->server_states is an array, not a pointer to a single record, so fix the places that access it to index it. (2) In the places that go through an address list to work out which one has the best priority, fix the loops to skip known failed addresses. Without this, the rotation algorithm may get stuck on addresses that are inaccessible or don't respond. This can be triggered manually by finding a server that advertises a non-routable address and giving it a higher priority, eg.: echo "add udp 192.168.0.0/16 3000" >/proc/fs/afs/addr_prefs if the server, say, includes the address 192.168.7.7 in its address list, and then attempting to access a volume on that server.

2024-05-10powerpc/fadump: setup additional parameters for dump capture kernelHari Bathini
For fadump case, passing additional parameters to dump capture kernel helps in minimizing the memory footprint for it and also provides the flexibility to disable components/modules, like hugepages, that are hindering the boot process of the special dump capture environment. Set up a dedicated parameter area to be passed to the capture kernel. This area type is defined as RTAS_FADUMP_PARAM_AREA. Sysfs attribute '/sys/kernel/fadump/bootargs_append' is exported to the userspace to specify the additional parameters to be passed to the capture kernel Signed-off-by: Hari Bathini <hbathini@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://msgid.link/20240509115755.519982-3-hbathini@linux.ibm.com
2024-05-10powerpc/pseries/fadump: add support for multiple boot memory regionsHari Bathini
Currently, fadump on pseries assumes a single boot memory region even though f/w supports more than one boot memory region. Add support for more boot memory regions to make the implementation flexible for any enhancements that introduce other region types. For this, rtas memory structure for fadump is updated to have multiple boot memory regions instead of just one. Additionally, methods responsible for creating the fadump memory structure during both the first and second kernel boot have been modified to take these multiple boot memory regions into account. Also, a new callback has been added to the fadump_ops structure to get the maximum boot memory regions supported by the platform.

2024-05-10fcntl: add F_DUPFD_QUERY fcntl()Linus Torvalds
Often userspace needs to know whether two file descriptors refer to the same struct file. For example, systemd uses this to filter out duplicate file descriptors in it's file descriptor store (cf. [1]) and vulkan uses it to compare dma-buf fds (cf. [2]). The only api we provided for this was kcmp() but that's not generally available or might be disallowed because it is way more powerful (allows ordering of file pointers, operates on non-current task) etc. So give userspace a simple way of comparing two file descriptors for sameness adding a new fcntl() F_DUDFD_QUERY.
