[PATCH OLK-6.6] bpf: Fix a sdiv overflow issue
by Xiaomeng Zhang 04 Nov '24

04 Nov '24

From: Yonghong Song <yonghong.song(a)linux.dev> mainline inclusion from mainline-v6.12-rc1 commit 7dd34d7b7dcf9309fc6224caf4dd5b35bedddcb7 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYRCO CVE: CVE-2024-49888 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Zac Ecob reported a problem where a bpf program may cause kernel crash due to the following error: Oops: divide error: 0000 [#1] PREEMPT SMP KASAN PTI The failure is due to the below signed divide: LLONG_MIN/-1 where LLONG_MIN equals to -9,223,372,036,854,775,808. LLONG_MIN/-1 is supposed to give a positive number 9,223,372,036,854,775,808, but it is impossible since for 64-bit system, the maximum positive number is 9,223,372,036,854,775,807. On x86_64, LLONG_MIN/-1 will cause a kernel exception. On arm64, the result for LLONG_MIN/-1 is LLONG_MIN. Further investigation found all the following sdiv/smod cases may trigger an exception when bpf program is running on x86_64 platform: - LLONG_MIN/-1 for 64bit operation - INT_MIN/-1 for 32bit operation - LLONG_MIN%-1 for 64bit operation - INT_MIN%-1 for 32bit operation where -1 can be an immediate or in a register. On arm64, there are no exceptions: - LLONG_MIN/-1 = LLONG_MIN - INT_MIN/-1 = INT_MIN - LLONG_MIN%-1 = 0 - INT_MIN%-1 = 0 where -1 can be an immediate or in a register. Insn patching is needed to handle the above cases and the patched codes produced results aligned with above arm64 result. The below are pseudo codes to handle sdiv/smod exceptions including both divisor -1 and divisor 0 and the divisor is stored in a register. sdiv: tmp = rX tmp += 1 /* [-1, 0] -> [0, 1] if tmp >(unsigned) 1 goto L2 if tmp == 0 goto L1 rY = 0 L1: rY = -rY; goto L3 L2: rY /= rX L3: smod: tmp = rX tmp += 1 /* [-1, 0] -> [0, 1] if tmp >(unsigned) 1 goto L1 if tmp == 1 (is64 ? goto L2 : goto L3) rY = 0; goto L2 L1: rY %= rX L2: goto L4 // only when !is64 L3: wY = wY // only when !is64 L4: [1] https://lore.kernel.org/bpf/tPJLTEh7S_DxFEqAI2Ji5MBSoZVg7_G-Py2iaZpAaWtM961… Reported-by: Zac Ecob <zacecob(a)protonmail.com> Closes: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… Signed-off-by: Yonghong Song <yonghong.song(a)linux.dev> Acked-by: Andrii Nakryiko <andrii(a)kernel.org> Link: https://lore.kernel.org/r/20240913150326.1187788-1-yonghong.song@linux.dev Signed-off-by: Alexei Starovoitov <ast(a)kernel.org> Conflicts: kernel/bpf/verifier.c [The conflicts were due to not merge the commits 74a7e76f8335e, c3a02b0607fda] Signed-off-by: Xiaomeng Zhang <zhangxiaomeng13(a)huawei.com> --- kernel/bpf/verifier.c | 93 +++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 89 insertions(+), 4 deletions(-) diff --git a/kernel/bpf/verifier.c b/kernel/bpf/verifier.c index d1041517a984..723edf37aa5a 100644 --- a/kernel/bpf/verifier.c +++ b/kernel/bpf/verifier.c @@ -18903,13 +18903,46 @@ static int do_misc_fixups(struct bpf_verifier_env *env) int i, ret, cnt, delta = 0; for (i = 0; i < insn_cnt; i++, insn++) { - /* Make divide-by-zero exceptions impossible. */ + /* Make sdiv/smod divide-by-minus-one exceptions impossible. */ + if ((insn->code == (BPF_ALU64 | BPF_MOD | BPF_K) || + insn->code == (BPF_ALU64 | BPF_DIV | BPF_K) || + insn->code == (BPF_ALU | BPF_MOD | BPF_K) || + insn->code == (BPF_ALU | BPF_DIV | BPF_K)) && + insn->off == 1 && insn->imm == -1) { + bool is64 = BPF_CLASS(insn->code) == BPF_ALU64; + bool isdiv = BPF_OP(insn->code) == BPF_DIV; + struct bpf_insn *patchlet; + struct bpf_insn chk_and_sdiv[] = { + BPF_RAW_INSN((is64 ?

[PATCH openEuler-22.03-LTS-SP1] gpiolib: fix memory leak in gpiochip_setup_dev()
by He Yujie 03 Nov '24

From: Zeng Heng <zengheng4(a)huawei.com> mainline inclusion from mainline-v6.1 commit ec851b23084b3a0af8bf0f5e51d33a8d678bdc49 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYRIL CVE: CVE-2022-48975 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Here is a backtrace report about memory leak detected in gpiochip_setup_dev(): unreferenced object 0xffff88810b406400 (size 512): comm "python3", pid 1682, jiffies 4295346908 (age 24.090s) backtrace: kmalloc_trace device_add device_private_init at drivers/base/core.c:3361 (inlined by) device_add at drivers/base/core.c:3411 cdev_device_add gpiolib_cdev_register gpiochip_setup_dev gpiochip_add_data_with_key gcdev_register() & gcdev_unregister() would call device_add() & device_del() (no matter CONFIG_GPIO_CDEV is enabled or not) to register/unregister device. However, if device_add() succeeds, some resource (like struct device_private allocated by device_private_init()) is not released by device_del(). Therefore, after device_add() succeeds by gcdev_register(), it needs to call put_device() to release resource in the error handle path. Here we move forward the register of release function, and let it release every piece of resource by put_device() instead of kfree().

[PATCH OLK-5.10] gpiolib: fix memory leak in gpiochip_setup_dev()

However, if device_add() succeeds, some resource (like struct device_private allocated by device_private_init()) is not released by device_del(). Therefore, after device_add() succeeds by gcdev_register(), it needs to call put_device() to release resource in the error handle path. Here we move forward the register of release function, and let it release every piece of resource by put_device() instead of kfree(). While at it, fix another subtle issue, i.e. when gc->ngpio is equal to 0, we still call kcalloc() and, in case of further error, kfree() on the ZERO_PTR pointer, which is not NULL. It's not a bug per se, but rather waste of the resources and potentially wrong expectation about contents of the gdev->descs variable.

Detect gso fraglist skbs with corrupted geometry (see below) and pass these to skb_segment instead of skb_segment_list, as the first can segment them correctly. Valid SKB_GSO_FRAGLIST skbs - consist of two or more segments - the head_skb holds the protocol headers plus first gso_size - one or more frag_list skbs hold exactly one segment - all but the last must be gso_size Optional datapath hooks such as NAT and BPF (bpf_skb_pull_data) can modify these skbs, breaking these invariants. In extreme cases they pull all data into skb linear. For UDP, this causes a NULL ptr deref in __udpv4_gso_segment_list_csum at udp_hdr(seg->next)->dest. Detect invalid geometry due to pull, by checking head_skb size. Don't just drop, as this may blackhole a destination. Convert to be able to pass to regular skb_segment.

But at that time, the work queue iwcm_wq was created via the function alloc_ordered_workqueue without the flag WQ_MEM_RECLAIM. Because the current process is trying to flush the whole iwcm_wq, if iwcm_wq doesn't have the flag WQ_MEM_RECLAIM, verify that the current process is not reclaiming memory or running on a workqueue which doesn't have the flag WQ_MEM_RECLAIM as that can break forward-progress guarantee leading to a deadlock.

It added one to uart_shutdown(), so the commit assumes, uport can be NULL in there. But right after that protection, there is an unprotected "uart_port_dtr_rts(uport, false);" call. That is invoked only if HUPCL is set, so I assume that is the reason why we do not see lots of these reports. Or it cannot be NULL at this point at all for some reason :P. Until the above is investigated, stay on the safe side and move this dereference to the if too. I got this inconsistency from Coverity under CID 1585130. Thanks.

[PATCH OLK-6.6] btrfs: fix uninitialized pointer free on read_alloc_one_name() error
by Baokun Li 02 Nov '24

02 Nov '24

From: Roi Martin <jroi.martin(a)gmail.com> stable inclusion from stable-v6.6.58 commit 7fc7c47b9ba0cf2d192f2117a64b24881b0b577f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB0EN2 CVE: CVE-2024-50087 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 2ab5e243c2266c841e0f6904fad1514b18eaf510 upstream. The function read_alloc_one_name() does not initialize the name field of the passed fscrypt_str struct if kmalloc fails to allocate the corresponding buffer. Thus, it is not guaranteed that fscrypt_str.name is initialized when freeing it. This is a follow-up to the linked patch that fixes the remaining instances of the bug introduced by commit e43eec81c516 ("btrfs: use struct qstr instead of name and namelen pairs").

Similar to ext4_split_extent_at(), we use *ppath directly as an input to ext4_ext_show_leaf(). Fix a spelling error by the way. Same problem in ext4_ext_handle_unwritten_extents(). Since 'path' is only used in ext4_ext_show_leaf(), remove 'path' and use *ppath directly. This issue is triggered only when EXT_DEBUG is defined and therefore does not affect functionality.

From: Tony Nguyen <anthony.l.nguyen(a)intel.com> stable inclusion from stable-v4.19.270 commit ef1d739dd1f362aec081278ff92f943c31eb177a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYRIW CVE: CVE-2022-48949 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit de5dc44370fbd6b46bd7f1a1e00369be54a041c8 upstream. When a MAC address is not assigned to the VF, that portion of the message sent to the VF is not set. The memory, however, is allocated from the stack meaning that information may be leaked to the VM.
