2025-02-21net: ipv4: Cache pmtu for all packet paths if multipath enabledVladimir Vdovin
[ Upstream commit 7d3f3b4367f315a61fc615e3138f3d320da8c466 ] Check number of paths by fib_info_num_path(), and update_or_create_fnhe() for every path. Problem is that pmtu is cached only for the oif that has received icmp message "need to frag", other oifs will still try to use "default" iface mtu. An example topology showing the problem: | host1 +---------+ | dummy0 | 10.179.20.18/32 mtu9000 +---------+ +-----------+----------------+ +---------+ +---------+ | ens17f0 | 10.179.2.141/31 | ens17f1 | 10.179.2.13/31 +---------+ +---------+ | (all here have mtu 9000) | +------+ +------+ | ro1 | 10.179.2.140/31 | ro2 | 10.179.2.12/31 +------+ +------+ | | ---------+------------+-------------------+------ | +-----+ | ro3 | 10.10.10.10 mtu1500 +-----+ | ======================================== some networks ======================================== | +-----+ | eth0| 10.10.30.30 mtu9000 +-----+ | host2 host1 have enabled multipath and sysctl net.ipv4.fib_multipath_hash_policy = 1: default proto static src 10.179.20.18 nexthop via 10.179.2.12 dev ens17f1 weight 1 nexthop via 10.179.2.140 dev ens17f0 weight 1 When host1 tries to do pmtud from 10.179.20.18/32 to host2, host1 receives at ens17f1 iface an icmp packet from ro3 that ro3 mtu=1500. And host1 caches it in nexthop exceptions cache. Problem is that it is cached only for the iface that has received icmp, and there is no way that ro3 will send icmp msg to host1 via another path. Host1 now have this routes to host2: ip r g 10.10.30.30 sport 30000 dport 443 10.10.30.30 via 10.179.2.12 dev ens17f1 src 10.179.20.18 uid 0 cache expires 521sec mtu 1500 ip r g 10.10.30.30 sport 30033 dport 443 10.10.30.30 via 10.179.2.140 dev ens17f0 src 10.179.20.18 uid 0 cache So when host1 tries again to reach host2 with mtu>1500, if packet flow is lucky enough to be hashed with oif=ens17f1 its ok, if oif=ens17f0 it blackholes and still gets icmp msgs from ro3 to ens17f1, until lucky day when ro3 will send it through another flow to ens17f0.

2025-02-21selftests: mptcp: connect: -f: no reconnectMatthieu Baerts (NGI0)
commit 5368a67307b3b2c347dc8965ac55b888be665934 upstream. The '-f' parameter is there to force the kernel to emit MPTCP FASTCLOSE by closing the connection with unread bytes in the receive queue. The xdisconnect() helper was used to stop the connection, but it does more than that: it will shut it down, then wait before reconnecting to the same address. This causes the mptcp_join's "fastclose test" to fail all the time. This failure is due to a recent change, with commit 218cc166321f ("selftests: mptcp: avoid spurious errors on disconnect"), but that went unnoticed because the test is currently ignored. The recent modification only shown an existing issue: xdisconnect() doesn't need to be used here, only the shutdown() part is needed.

2025-02-21udp: gso: do not drop small packets when PMTU reducesYan Zhai
[ Upstream commit 235174b2bed88501fda689c113c55737f99332d8 ] Commit 4094871db1d6 ("udp: only do GSO if # of segs > 1") avoided GSO for small packets. But the kernel currently dismisses GSO requests only after checking MTU/PMTU on gso_size. This means any packets, regardless of their payload sizes, could be dropped when PMTU becomes smaller than requested gso_size. We encountered this issue in production and it caused a reliability problem that new QUIC connection cannot be established before PMTU cache expired, while non GSO sockets still worked fine at the same time. Ideally, do not check any GSO related constraints when payload size is smaller than requested gso_size, and return EMSGSIZE instead of EINVAL on MTU/PMTU check failure to be more specific on the error cause.

In the case of a test that uses the special option ${KERNEL_VERSION} in one of its settings but has no configuration available in ${OUTPUT_DIR}, for example if it's a new empty directory, then the `make kernelrelease` call will fail and the subroutine will chomp an empty string, silently.

2025-02-01ipv6: Fix soft lockups in fib6_select_path under high next hop churnOmid Ehtemam-Haghighi
commit d9ccb18f83ea2bb654289b6ecf014fd267cc988b upstream. Soft lockups have been observed on a cluster of Linux-based edge routers located in a highly dynamic environment. Using the `bird` service, these routers continuously update BGP-advertised routes due to frequently changing nexthop destinations, while also managing significant IPv6 traffic. The lockups occur during the traversal of the multipath circular linked-list in the `fib6_select_path` function, particularly while iterating through the siblings in the list. The issue typically arises when the nodes of the linked list are unexpectedly deleted concurrently on a different core—indicated by their 'next' and 'previous' elements pointing back to the node itself and their reference count dropping to zero. This results in an infinite loop, leading to a soft lockup that triggers a system panic via the watchdog timer. Apply RCU primitives in the problematic code sections to resolve the issue. Where necessary, update the references to fib6_siblings to annotate or use the RCU APIs. Include a test script that reproduces the issue.

Address the issue explicitly waiting for all the relevant sockets to reach a closed status before performing the disconnect.

2024-12-27selftests/bpf: Use asm constraint "m" for LoongArchTiezhu Yang
commit 29d44cce324dab2bd86c447071a596262e7109b6 upstream. Currently, LoongArch LLVM does not support the constraint "o" and no plan to support it, it only supports the similar constraint "m", so change the constraints from "nor" in the "else" case to arch-specific "nmr" to avoid the build error such as "unexpected asm memory constraint" for LoongArch.

However, it is not the case and so other packets are filling the buffers as well. Therefore, the test sometimes fails because it is reading a maximum occupancy that is larger than expected.

However the filesystem image doesn't actually occupy 2MB on "disk" (actually RAM, due to tmpfs). On 4K kernels the ext4.img uses ~84KB of actual space (according to du), which just fits. However on 64K PAGE_SIZE kernels the ext4.img takes at least 256KB, which is too large to fit in the tmpfs, hence the errors. It seems fraught to rely on the ext4.img taking less space on disk than the allocated size, so instead create the tmpfs with a size of 2MB. With that all 21 tests pass on 64K PAGE_SIZE kernels.

The original commit that brought VDSO support into powerpc/64 has the following explanation: Note that the symbols exposed by the vDSO aren't "normal" function symbols, apps can't be expected to link against them directly, the vDSO's are both seen as if they were linked at 0 and the symbols just contain offsets to the various functions. This is done on purpose to avoid a relocation step (ppc64 functions normally have descriptors with abs addresses in them). When glibc uses those functions, it's expected to use it's own trampolines that know how to reach them. The descriptors it's talking about are the OPD function descriptors used on ABI v1 (big endian). But it would be more correct for a text symbol to have type function, even if there's no function descriptor for it. glibc has a special case already for handling the VDSO symbols which creates a fake opd pointing at the kernel symbol. So changing the VDSO symbol type to function shouldn't affect that. For ABI v2, there is no function descriptors and VDSO functions can safely have function type. So lets flag VDSO entry points as functions and revert the selftest change.

2024-12-14selftests/bpf: Fix backtrace printing for selftests crashesEduard Zingerman
[ Upstream commit 5bf1557e3d6a69113649d831276ea2f97585fc33 ] test_progs uses glibc specific functions backtrace() and backtrace_symbols_fd() to print backtrace in case of SIGSEGV. Recent commit (see fixes) updated test_progs.c to define stub versions of the same functions with attriubte "weak" in order to allow linking test_progs against musl libc. Unfortunately this broke the backtrace handling for glibc builds. As it turns out, glibc defines backtrace() and backtrace_symbols_fd() as weak: $ llvm-readelf --symbols /lib64/libc.so.6 \ | grep -P '( backtrace_symbols_fd| backtrace)$' 4910: 0000000000126b40 161 FUNC WEAK DEFAULT 16 backtrace 6843: 0000000000126f90 852 FUNC WEAK DEFAULT 16 backtrace_symbols_fd So does test_progs: $ llvm-readelf --symbols test_progs \ | grep -P '( backtrace_symbols_fd| backtrace)$' 2891: 00000000006ad190 15 FUNC WEAK DEFAULT 13 backtrace 11215: 00000000006ad1a0 41 FUNC WEAK DEFAULT 13 backtrace_symbols_fd In such situation dynamic linker is not obliged to favour glibc implementation over the one defined in test_progs.

2024-12-14selftests/resctrl: Protect against array overrun during iMC config parsingReinette Chatre
[ Upstream commit 48ed4e799e8fbebae838dca404a8527763d41191 ] The MBM and MBA tests need to discover the event and umask with which to configure the performance event used to measure read memory bandwidth. This is done by parsing the /sys/bus/event_source/devices/uncore_imc_<imc instance>/events/cas_count_read file for each iMC instance that contains the formatted output: "event=<event>,umask=<umask>" Parsing of cas_count_read contents is done by initializing an array of MAX_TOKENS elements with tokens (deliminated by "=,") from this file. Remove the unnecessary append of a delimiter to the string needing to be parsed. Per the strtok() man page: "delimiter bytes at the start or end of the string are ignored". This has no impact on the token placement within the array. After initialization, the actual event and umask is determined by parsing the tokens directly following the "event" and "umask" tokens respectively. Iterating through the array up to index "i < MAX_TOKENS" but then accessing index "i + 1" risks array overrun during the final iteration. Avoid array overrun by ensuring that the index used within for loop will always be valid.

[ Upstream commit 7e893dc81de3e342156389ea0b83ec7d07f25281 ] When printing the signal context's PC, we use a "%lx" format specifier, which matches the common userland (glibc's) definition of uint64_t as an "unsigned long". However the structure in question is defined in a kernel uapi header, which uses a self defined __u64 type, and the arm64 kernel headers define this using "int-ll64.h", so it becomes an "unsigned long long". This mismatch leads to the usual compiler warning. The common fix would be to use "PRIx64", but because this is defined by the userland's toolchain libc headers, it wouldn't match as well. Since we know the exact type of __u64, just use "%llx" here instead, to silence this warning. This also fixes a more severe typo: "$lx" is not a valid format specifier.

2024-11-22net/sched: taprio: extend minimum interval restriction to entire cycle tooVladimir Oltean
[ Upstream commit fb66df20a7201e60f2b13d7f95d031b31a8831d3 ] It is possible for syzbot to side-step the restriction imposed by the blamed commit in the Fixes: tag, because the taprio UAPI permits a cycle-time different from (and potentially shorter than) the sum of entry intervals. We need one more restriction, which is that the cycle time itself must be larger than N * ETH_ZLEN bit times, where N is the number of schedule entries. This restriction needs to apply regardless of whether the cycle time came from the user or was the implicit, auto-calculated value, so we move the existing "cycle == 0" check outside the "if "(!new->cycle_time)" branch. This way covers both conditions and scenarios. Add a selftest which illustrates the issue triggered by syzbot.

2024-11-14kselftest/arm64: Initialise current at build time in signal testsMark Brown
commit 6e4b4f0eca88e47def703f90a403fef5b96730d5 upstream. When building with clang the toolchain refuses to link the signals testcases since the assembly code has a reference to current which has no initialiser so is placed in the BSS: /tmp/signals-af2042.o: in function `fake_sigreturn': <unknown>:51:(.text+0x40): relocation truncated to fit: R_AARCH64_LD_PREL_LO19 against symbol `current' defined in .bss section in /tmp/test_signals-ec1160.o Since the first statement in main() initialises current we may as well fix this by moving the initialisation to build time so the variable doesn't end up in the BSS.
