2024-05-13Merge tag 'slab-for-6.10' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab Pull slab updates from Vlastimil Babka: "This time it's mostly random cleanups and fixes, with two performance fixes that might have significant impact, but limited to systems experiencing particular bad corner case scenarios rather than general performance improvements. The memcg hook changes are going through the mm tree due to dependencies. - Prevent stalls when reading /proc/slabinfo (Jianfeng Wang) This fixes the long-standing problem that can happen with workloads that have alloc/free patterns resulting in many partially used slabs (in e.g. dentry cache). Reading /proc/slabinfo will traverse the long partial slab list under spinlock with disabled irqs and thus can stall other processes or even trigger the lockup detection. The traversal is only done to count free objects so that <active_objs> column can be reported along with <num_objs>. To avoid affecting fast paths with another shared counter (attempted in the past) or complex partial list traversal schemes that allow rescheduling, the chosen solution resorts to approximation - when the partial list is over 10000 slabs long, we will only traverse first 5000 slabs from head and tail each and use the average of those to estimate the whole list. Both head and tail are used as the slabs near head to tend to have more free objects than the slabs towards the tail. It is expected the approximation should not break existing /proc/slabinfo consumers. The <num_objs> field is still accurate and reflects the overall kmem_cache footprint. The <active_objs> was already imprecise due to cpu and percpu-partial slabs, so can't be relied upon to determine exact cache usage. The difference between <active_objs> and <num_objs> is mainly useful to determine the slab fragmentation, and that will be possible even with the approximation in place. - Prevent allocating many slabs when a NUMA node is full (Chen Jun) Currently, on NUMA systems with a node under significantly bigger pressure than other nodes, the fallback strategy may result in each kmalloc_node() that can't be safisfied from the preferred node, to allocate a new slab on a fallback node, and not reuse the slabs already on that node's partial list. This is now fixed and partial lists of fallback nodes are checked even for kmalloc_node() allocations. It's still preferred to allocate a new slab on the requested node before a fallback, but only with a GFP_NOWAIT attempt, which will fail quickly when the node is under a significant memory pressure. - More SLAB removal related cleanups (Xiu Jianfeng, Hyunmin Lee) - Fix slub_kunit self-test with hardened freelists (Guenter Roeck) - Mark racy accesses for KCSAN (linke li) - Misc cleanups (Xiongwei Song, Haifeng Xu, Sangyun Kim)" * tag 'slab-for-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab: mm/slub: remove the check for NULL kmalloc_caches mm/slub: create kmalloc 96 and 192 caches regardless cache size order mm/slub: mark racy access on slab->freelist slub: use count_partial_free_approx() in slab_out_of_memory() slub: introduce count_partial_free_approx() slub: Set __GFP_COMP in kmem_cache by default mm/slub: remove duplicate initialization for early_kmem_cache_node_alloc() mm/slub: correct comment in do_slab_free() mm/slub, kunit: Use inverted data to corrupt kmem cache mm/slub: simplify get_partial_node() mm/slub: add slub_get_cpu_partial() helper mm/slub: remove the check of !kmem_cache_has_cpu_partial() mm/slub: Reduce memory consumption in extreme scenarios mm/slub: mark racy accesses on slab->slabs mm/slub: remove dummy slabinfo functions

This allows pre-KCSAN code to be correctly (if approximately) instrumented withh very little effort, and also provides people reading the code a clear indication that the variable is in fact shared.

This topic came up again when Paul McKenney noticed that parts of the RCU code already rely on byte access and do not work on alpha EV5 reliably, so we decided on using my series to avoid the problem entirely. Al Viro did another series for alpha to address all the known build issues. I rebased his patches without any further changes and included it as a baseline for my work here to avoid conflicts and allow backporting the fixes to stable kernels for the now removed hardware support as well" [ I dearly loved alpha back in the days, but the lack of byte and word operations was a horrible mistake and made everything worse - including very much the crazy IO contortions that resulted from it.

2024-05-13dmaengine: idxd: add a write() method for applications to submit workNikhil Rao
After the patch to restrict the use of mmap() to CAP_SYS_RAWIO for the currently existing devices, most applications can no longer make use of the accelerators as in production "you don't run things as root". To keep the DSA and IAA accelerators usable, hook up a write() method so that applications can still submit work. In the write method, sufficient input validation is performed to avoid the security issue that required the mmap CAP_SYS_RAWIO check. One complication is that the DSA device allows for indirect ("batched") descriptors. There is no reasonable way to do the input validation on these indirect descriptors so the write() method will not allow these to be submitted to the hardware on affected hardware, and the sysfs enumeration of support for the opcode is also removed. Early performance data shows that the performance delta for most common cases is within the noise.

2024-05-13dmaengine: idxd: add a new security check to deal with a hardware erratumArjan van de Ven
On Sapphire Rapids and related platforms, the DSA and IAA devices have an erratum that causes direct access (for example, by using the ENQCMD or MOVDIR64 instructions) from untrusted applications to be a security problem. To solve this, add a flag to the PCI device enumeration and device structures to indicate the presence/absence of this security exposure. In the mmap() method of the device, this flag is then used to enforce that the user has the CAP_SYS_RAWIO capability. In a future patch, a write() based method will be added that allows untrusted applications submit work to the accelerator, where the kernel can do sanity checking on the user input to ensure secure operation of the accelerator.

2024-05-12bpf: make list_for_each_entry portableJose E. Marchesi
[Changes from V1: - The __compat_break has been abandoned in favor of a more readable can_loop macro that can be used anywhere, including loop conditions.] The macro list_for_each_entry is defined in bpf_arena_list.h as follows: #define list_for_each_entry(pos, head, member) \ for (void * ___tmp = (pos = list_entry_safe((head)->first, \ typeof(*(pos)), member), \ (void *)0); \ pos && ({ ___tmp = (void *)pos->member.next; 1; }); \ cond_break, \ pos = list_entry_safe((void __arena *)___tmp, typeof(*(pos)), member)) The macro cond_break, in turn, expands to a statement expression that contains a `break' statement. Compound statement expressions, and the subsequent ability of placing statements in the header of a `for' loop, are GNU extensions. Unfortunately, clang implements this GNU extension differently than GCC: - In GCC the `break' statement is bound to the containing "breakable" context in which the defining `for' appears. If there is no such context, GCC emits a warning: break statement without enclosing `for' o `switch' statement. - In clang the `break' statement is bound to the defining `for'. If the defining `for' is itself inside some breakable construct, then clang emits a -Wgcc-compat warning. This patch adds a new macro can_loop to bpf_experimental, that implements the same logic than cond_break but evaluates to a boolean expression. The patch also changes all the current instances of usage of cond_break withing the header of loop accordingly. Tested in bpf-next master. No regressions. Signed-off-by: Jose E.

2024-05-12bpf: disable strict aliasing in test_global_func9.cJose E. Marchesi
The BPF selftest test_global_func9.c performs type punning and breaks srict-aliasing rules. In particular, given: int global_func9(struct __sk_buff *skb) { int result = 0; [...] { const struct C c = {.x = skb->len, .y = skb->family }; result |= foo((const struct S *)&c); } } When building with strict-aliasing enabled (the default) the initialization of `c' gets optimized away in its entirely: [... no initialization of `c' ...] r1 = r10 r1 += -40 call foo w0 |= w6 Since GCC knows that `foo' accesses s->x, we get a "maybe uninitialized" warning. On the other hand, when strict-aliasing is disabled GCC only optimizes away the store to `.y': r1 = *(u32 *) (r6+0) *(u32 *) (r10+-40) = r1 ; This is .x = skb->len in `c' r1 = r10 r1 += -40 call foo w0 |= w6 In this case the warning is not emitted, because s-> is initialized. This patch disables strict aliasing in this test when building with GCC. clang seems to not optimize this particular code even when strict aliasing is enabled. Tested in bpf-next master.

GCC detects that cpumask is never initialized and reports an error. This patch removes the spurious non required definitions of cpumask. -- progs/dynptr_fail.c -- progs/dynptr_fail.c:1444:9: error: ‘ptr1’ may be used uninitialized [-Werror=maybe-uninitialized] 1444 | bpf_dynptr_clone(&ptr1, &ptr2); Many of the tests in the file are related to the detection of uninitialized pointers by the verifier. GCC is able to detect possible uninitialized values, and reports this as an error. The patch initializes all of the previous uninitialized structs. -- progs/test_tunnel_kern.c -- progs/test_tunnel_kern.c:590:9: error: array subscript 1 is outside array bounds of ‘struct geneve_opt[1]’ [-Werror=array-bounds=] 590 | *(int *) &gopt.opt_data = bpf_htonl(0xdeadbeef); | ^~~~~~~~~~~~~~~~~~~~~~~ progs/test_tunnel_kern.c:575:27: note: at offset 4 into object ‘gopt’ of size 4 575 | struct geneve_opt gopt; This tests accesses beyond the defined data for the struct geneve_opt which contains as last field "u8 opt_data[0]" which clearly does not get reserved space (in stack) in the function header. This pattern is repeated in ip6geneve_set_tunnel and geneve_set_tunnel functions. GCC is able to see this and emits a warning. The patch introduces a local struct that allocates enough space to safely allow the write to opt_data field. -- progs/jeq_infer_not_null_fail.c -- progs/jeq_infer_not_null_fail.c:21:40: error: array subscript ‘struct bpf_map[0]’ is partly outside array bounds of ‘struct <anonymous>[1]’ [-Werror=array-bounds=] 21 | struct bpf_map *inner_map = map->inner_map_meta; | ^~ progs/jeq_infer_not_null_fail.c:14:3: note: object ‘m_hash’ of size 32 14 | } m_hash SEC(".maps"); This example defines m_hash in the context of the compilation unit and casts it to struct bpf_map which is much smaller than the size of struct bpf_map. It errors out in GCC when it attempts to access an element that would be defined in struct bpf_map outsize of the defined limits for m_hash. This patch disables the warning through a GCC pragma.

The bpf_htons macro (and similarly the bpf_ntohs macro) expand to a ternary operation using either __builtin_bswap16 or ___bpf_swab16 to swap the bytes, depending on whether the expression is constant. For an expression, with 'value' as a u16, like: bpf_htons (value & 0xf000) The entire (value & 0xf000) is 'x' in the expansion of ___bpf_swab16 and we get as one part of the expanded swab16: ((__u16)(value & 0xf000) << 8 >> 8 << 8 This will always evaluate to 0, which is intentional since this subexpression deals with the byte guaranteed to be 0 by the mask. However, GCC warns because the precise reason this always evaluates to 0 is an overflow. Specifically, the plain 0xf000 in the expression is a signed 32-bit integer, which causes 'value' to also be promoted to a signed 32-bit integer, and the combination of the 8-bit left shift and down-cast back to __u16 results in a signed overflow (really a 'warning: overflow in conversion from int to __u16' which is propegated up through the rest of the expression leading to the ultimate overflow warning above), which is a valid warning despite being the intended result of this code. Clang does not warn on this case, likely because it performs constant folding later in the compilation process relative to GCC. It seems that by the time clang does constant folding for this expression, the side of the ternary with this overflow has already been discarded. Fortunately, this warning is easily silenced by simply making the 0xf000 mask explicitly unsigned. This has no impact on the result.

2024-05-12selftests/bpf: Migrate sendmsg deny test casesJordan Rife
This set of tests checks that sendmsg calls are rejected (return -EPERM) when the sendmsg* hook returns 0. Replace those in bpf/test_sock_addr.c with corresponding tests in prog_tests/sock_addr.c.

2024-05-12selftests/bpf: Handle SYSCALL_EPERM and SYSCALL_ENOTSUPP test casesJordan Rife
In preparation to move test cases from bpf/test_sock_addr.c that expect system calls to return ENOTSUPP or EPERM, this patch propagates errno from relevant system calls up to test_sock_addr() where the result can be checked.

2024-05-12selftests/bpf: Handle ATTACH_REJECT test casesJordan Rife
In preparation to move test cases from bpf/test_sock_addr.c that expect ATTACH_REJECT, this patch adds BPF_SKEL_FUNCS_RAW to generate load and destroy functions that use bpf_prog_attach() to control the attach_type. The normal load functions use bpf_program__attach_cgroup which does not have the same degree of control over the attach type, as bpf_program_attach_fd() calls bpf_link_create() with the attach type extracted from prog using bpf_program__expected_attach_type(). It is currently not possible to modify the attach type before bpf_program__attach_cgroup() is called, since bpf_program__set_expected_attach_type() has no effect after the program is loaded.

2024-05-12selftests/bpf: Use program name for skel load/destroy functionsJordan Rife
In preparation to migrate tests from bpf/test_sock_addr.c to sock_addr.c, update BPF_SKEL_FUNCS so that it generates functions based on prog_name instead of skel_name. This allows us to differentiate between programs in the same skeleton.

2024-05-12selftests/bpf: Migrate recvmsg* return code tests to verifier_sock_addr.cJordan Rife
This set of tests check that the BPF verifier rejects programs with invalid return codes (recvmsg4 and recvmsg6 hooks can only return 1). This patch replaces the tests in test_sock_addr.c with verifier_sock_addr.c, a new verifier prog_tests for sockaddr hooks, in a step towards fully retiring test_sock_addr.c.

2024-05-12riscv, bpf: make some atomic operations fully orderedPuranjay Mohan
The BPF atomic operations with the BPF_FETCH modifier along with BPF_XCHG and BPF_CMPXCHG are fully ordered but the RISC-V JIT implements all atomic operations except BPF_CMPXCHG with relaxed ordering. Section 8.1 of the "The RISC-V Instruction Set Manual Volume I: Unprivileged ISA" [1], titled, "Specifying Ordering of Atomic Instructions" says: | To provide more efficient support for release consistency [5], each | atomic instruction has two bits, aq and rl, used to specify additional | memory ordering constraints as viewed by other RISC-V harts. and | If only the aq bit is set, the atomic memory operation is treated as | an acquire access. | If only the rl bit is set, the atomic memory operation is treated as a | release access. | | If both the aq and rl bits are set, the atomic memory operation is | sequentially consistent. Fix this by setting both aq and rl bits as 1 for operations with BPF_FETCH and BPF_XCHG.
