Commit 8f84780b84d6 ("netfilter: flowtable: allow unidirectional rules") made unidirectional flow offload possible, while completely ignoring (and breaking) bidirectional flow offload for nftables.

2024-02-15netfilter: nat: restore default DNAT behaviorKyle Swenson1-1/+4
When a DNAT rule is configured via iptables with different port ranges, iptables -t nat -A PREROUTING -p tcp -d 10.0.0.2 -m tcp --dport 32000:32010 -j DNAT --to-destination 192.168.0.10:21000-21010 we seem to be DNATing to some random port on the LAN side. While this is expected if --random is passed to the iptables command, it is not expected without passing --random. The expected behavior (and the observed behavior prior to the commit in the "Fixes" tag) is the traffic will be DNAT'd to 192.168.0.10:21000 unless there is a tuple collision with that destination. In that case, we expect the traffic to be instead DNAT'd to 192.168.0.10:21001, so on so forth until the end of the range. This patch intends to restore the behavior observed prior to the "Fixes" tag.

2024-02-15kbuild: use 4-space indentation when followed by conditionalsMasahiro Yamada4-14/+14
GNU Make manual [1] clearly forbids a tab at the beginning of the conditional directive line: "Extra spaces are allowed and ignored at the beginning of the conditional directive line, but a tab is not allowed." This will not work for the next release of GNU Make, hence commit 82175d1f9430 ("kbuild: Replace tabs with spaces when followed by conditionals") replaced the inappropriate tabs with 8 spaces. However, the 8-space indentation cannot be visually distinguished. Linus suggested 2-4 spaces for those nested if-statements. [2] This commit redoes the replacement with 4 spaces.

2024-02-14lsm: fix integer overflow in lsm_set_self_attr() syscallJann Horn1-2/+5
security_setselfattr() has an integer overflow bug that leads to out-of-bounds access when userspace provides bogus input: `lctx->ctx_len + sizeof(*lctx)` is checked against `lctx->len` (and, redundantly, also against `size`), but there are no checks on `lctx->ctx_len`. Therefore, userspace can provide an `lsm_ctx` with `->ctx_len` set to a value between `-sizeof(struct lsm_ctx)` and -1, and this bogus `->ctx_len` will then be passed to an LSM module as a buffer length, causing LSM modules to perform out-of-bounds accesses. The following reproducer will demonstrate this under ASAN (if AppArmor is loaded as an LSM): ``` struct lsm_ctx { uint64_t id; uint64_t flags; uint64_t len; uint64_t ctx_len; char ctx[]; }; int main(void) { size_t size = sizeof(struct lsm_ctx); struct lsm_ctx *ctx = malloc(size); ctx->id = 104/*LSM_ID_APPARMOR*/; ctx->flags = 0; ctx->len = size; ctx->ctx_len = -sizeof(struct lsm_ctx); syscall( 460/*__NR_lsm_set_self_attr*/, /*attr=*/ 100/*LSM_ATTR_CURRENT*/, /*ctx=*/ ctx, /*size=*/ size, /*flags=*/ 0 ); } ``` Fixes: a04a1198088a ("LSM: syscalls for current process attributes") Signed-off-by: Jann Horn <[email protected]> Acked-by: Casey Schaufler <[email protected]> [PM: subj tweak, removed ref to ASAN splat that isn't included] Signed-off-by: Paul Moore <[email protected]>

2024-02-14tracing: Inform kmemleak of saved_cmdlines allocationSteven Rostedt (Google)1-0/+3
The allocation of the struct saved_cmdlines_buffer structure changed from: s = kmalloc(sizeof(*s), GFP_KERNEL); s->saved_cmdlines = kmalloc_array(TASK_COMM_LEN, val, GFP_KERNEL); to: orig_size = sizeof(*s) + val * TASK_COMM_LEN; order = get_order(orig_size); size = 1 << (order + PAGE_SHIFT); page = alloc_pages(GFP_KERNEL, order); if (!page) return NULL; s = page_address(page); memset(s, 0, sizeof(*s)); s->saved_cmdlines = kmalloc_array(TASK_COMM_LEN, val, GFP_KERNEL); Where that s->saved_cmdlines allocation looks to be a dangling allocation to kmemleak. That's because kmemleak only keeps track of kmalloc() allocations. For allocations that use page_alloc() directly, the kmemleak needs to be explicitly informed about it. Add kmemleak_alloc() and kmemleak_free() around the page allocation so that it doesn't give the following false positive: unreferenced object 0xffff8881010c8000 (size 32760): comm "swapper", pid 0, jiffies 4294667296 hex dump (first 32 bytes): ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ backtrace (crc ae6ec1b9): [<ffffffff86722405>] kmemleak_alloc+0x45/0x80 [<ffffffff8414028d>] __kmalloc_large_node+0x10d/0x190 [<ffffffff84146ab1>] __kmalloc+0x3b1/0x4c0 [<ffffffff83ed7103>] allocate_cmdlines_buffer+0x113/0x230 [<ffffffff88649c34>] tracer_alloc_buffers.isra.0+0x124/0x460 [<ffffffff8864a174>] early_trace_init+0x14/0xa0 [<ffffffff885dd5ae>] start_kernel+0x12e/0x3c0 [<ffffffff885f5758>] x86_64_start_reservations+0x18/0x30 [<ffffffff885f582b>] x86_64_start_kernel+0x7b/0x80 [<ffffffff83a001c3>] secondary_startup_64_no_verify+0x15e/0x16b Link: https://lore.kernel.org/linux-trace-kernel/[email protected]/ Link: https://lore.kernel.org/linux-trace-kernel/[email protected] Cc: Masami Hiramatsu <[email protected]> Cc: Mathieu Desnoyers <[email protected]> Cc: Catalin Marinas <[email protected]> Fixes: 44dc5c41b5b1 ("tracing: Fix wasted memory in saved_cmdlines logic") Reported-by: Kalle Valo <[email protected]> Tested-by: Kalle Valo <[email protected]> Signed-off-by: Steven Rostedt (Google) <[email protected]>

KVM x86 fixes for 6.8: - Make a KVM_REQ_NMI request while handling KVM_SET_VCPU_EVENTS if and only if the incoming events->nmi.pending is non-zero. If the target vCPU is in the UNITIALIZED state, the spurious request will result in KVM exiting to userspace, which in turn causes QEMU to constantly acquire and release QEMU's global mutex, to the point where the BSP is unable to make forward progress. - Fix a type (u8 versus u64) goof that results in pmu->fixed_ctr_ctrl being incorrectly truncated, and ultimately causes KVM to think a fixed counter has already been disabled (KVM thinks the old value is '0'). - Fix a stack leak in KVM_GET_MSRS where a failed MSR read from userspace that is ultimately ignored due to ignore_msrs=true doesn't zero the output as intended.

2024-02-14can: j1939: prevent deadlock by changing j1939_socks_lock to rwlockZiqi Zhao3-14/+14
The following 3 locks would race against each other, causing the deadlock situation in the Syzbot bug report: - j1939_socks_lock - active_session_list_lock - sk_session_queue_lock A reasonable fix is to change j1939_socks_lock to an rwlock, since in the rare situations where a write lock is required for the linked list that j1939_socks_lock is protecting, the code does not attempt to acquire any more locks. This would break the circular lock dependency, where, for example, the current thread already locks j1939_socks_lock and attempts to acquire sk_session_queue_lock, and at the same time, another thread attempts to acquire j1939_socks_lock while holding sk_session_queue_lock. NOTE: This patch along does not fix the unregister_netdevice bug reported by Syzbot; instead, it solves a deadlock situation to prepare for one or more further patches to actually fix the Syzbot bug, which appears to be a reference counting problem within the j1939 codebase.

Change the code to use consistent types here to address the warning and make it more robust against workqueue interface changes. Side note: the use of a delayed workqueue for cleaning up TX descriptors is probably a bad idea since this introduces a noticeable delay.

2024-02-14powerpc/pseries: fix accuracy of stolen timeShrikanth Hegde1-2/+6
powerVM hypervisor updates the VPA fields with stolen time data. It currently reports enqueue_dispatch_tb and ready_enqueue_tb for this purpose. In linux these two fields are used to report the stolen time. The VPA fields are updated at the TB frequency. On powerPC its mostly set at 512Mhz. Hence this needs a conversion to ns when reporting it back as rest of the kernel timings are in ns. This conversion is already handled in tb_to_ns function. So use that function to report accurate stolen time. Observed this issue and used an Capped Shared Processor LPAR(SPLPAR) to simplify the experiments. In all these cases, 100% VP Load is run using stress-ng workload. Values of stolen time is in percentages as reported by mpstat.

Commit e320a76db4b0 ("powerpc/cputable: Split cpu_specs[] out of cputable.h") moved the cpu_specs to separate header files. Previously PPC_FEATURE_BOOKE was enabled by CONFIG_PPC_BOOK3E_64. The definition in cpu_specs_e500mc.h for PPC64 no longer enables PPC_FEATURE_BOOKE. This breaks user space reading the ELF hwcaps and expect PPC_FEATURE_BOOKE. Debugging an application with gdb is no longer working on e5500/e6500 because the 64-bit detection relies on PPC_FEATURE_BOOKE for Book-E.

2024-02-14powerpc/kasan: Limit KASAN thread size increase to 32KBMichael Ellerman1-1/+1
KASAN is seen to increase stack usage, to the point that it was reported to lead to stack overflow on some 32-bit machines (see link). To avoid overflows the stack size was doubled for KASAN builds in commit 3e8635fb2e07 ("powerpc/kasan: Force thread size increase with KASAN"). However with a 32KB stack size to begin with, the doubling leads to a 64KB stack, which causes build errors: arch/powerpc/kernel/switch.S:249: Error: operand out of range (0x000000000000fe50 is not between 0xffffffffffff8000 and 0x0000000000007fff) Although the asm could be reworked, in practice a 32KB stack seems sufficient even for KASAN builds - the additional usage seems to be in the 2-3KB range for a 64-bit KASAN build. So only increase the stack for KASAN if the stack size is < 32KB.

2024-02-13ASoC: cs35l56: Workaround for ACPI with broken spk-id-gpios propertyRichard Fitzgerald1-0/+93
The ACPI in some SoundWire laptops has a spk-id-gpios property but it points to the wrong Device node. This patch adds a workaround to try to get the GPIO directly from the correct Device node. If the attempt to get the GPIOs from the property fails, the workaround looks for the SDCA node "AF01", which is where the GpioIo resource is defined. If this exists, a spk-id-gpios mapping is added to that node and then the GPIO is got from that node using the property.

2024-02-13selftests: net: more pmtu.sh fixesPaolo Abeni1-2/+2
The netdev CI is reporting failures for the pmtu test: [ 115.929264] br0: port 2(vxlan_a) entered forwarding state # 2024/02/08 17:33:22 socat[7871] E bind(7, {AF=10 [0000:0000:0000:0000:0000:0000:0000:0000]:50000}, 28): Address already in use # 2024/02/08 17:33:22 socat[7877] E write(7, 0x5598fb6ff000, 8192): Connection refused # TEST: IPv6, bridged vxlan4: PMTU exceptions [FAIL] # File size 0 mismatches exepcted value in locally bridged vxlan test The root cause is apparently a socket created by a previous iteration of the relevant loop still lasting in LAST_ACK state. Note that even the file size check is racy, the receiver process dumping the file could still be running in background Allow the listener to bound on the same local port via SO_REUSEADDR and collect file output file size only after the listener completion.

2024-02-13selftests: net: more strict check in net_helperPaolo Abeni1-4/+7
The helper waiting for a listener port can match any socket whose hexadecimal representation of source or destination addresses matches that of the given port. Additionally, any socket state is accepted. All the above can let the helper return successfully before the relevant listener is actually ready, with unexpected results. So far I could not find any related failure in the netdev CI, but the next patch is going to make the critical event more easily reproducible. Address the issue matching the port hex only vs the relevant socket field and additionally checking the socket state for TCP sockets.
