[PATCH v2 04/13] KVM: nSVM: Fix consistency checks for NP_ENABLE

by Yosry Ahmed

KVM currenty fails a nested VMRUN and injects VMEXIT_INVALID (aka SVM_EXIT_ERR) if L1 sets NP_ENABLE and the host does not support NPTs. On first glance, it seems like the check should actually be for guest_cpu_cap_has(X86_FEATURE_NPT) instead, as it is possible for the host to support NPTs but the guest CPUID to not advertise it. However, the consistency check is not architectural to begin with. The APM does not mention VMEXIT_INVALID if NP_ENABLE is set on a processor that does not have X86_FEATURE_NPT. Hence, NP_ENABLE should be ignored if X86_FEATURE_NPT is not available for L1. Apart from the consistency check, this is currently the case because NP_ENABLE is actually copied from VMCB01 to VMCB02, not from VMCB12. On the other hand, the APM does mention two other consistency checks for NP_ENABLE, both of which are missing (paraphrased): In Volume #2, 15.25.3 (24593—Rev. 3.42—March 2024): If VMRUN is executed with hCR0.PG cleared to zero and NP_ENABLE set to 1, VMRUN terminates with #VMEXIT(VMEXIT_INVALID) In Volume #2, 15.25.4 (24593—Rev. 3.42—March 2024): When VMRUN is executed with nested paging enabled (NP_ENABLE = 1), the following conditions are considered illegal state combinations, in addition to those mentioned in “Canonicalization and Consistency Checks”: • Any MBZ bit of nCR3 is set. • Any G_PAT.PA field has an unsupported type encoding or any reserved field in G_PAT has a nonzero value. Replace the existing consistency check with consistency checks on hCR0.PG and nCR3. Only perform the consistency checks if L1 has X86_FEATURE_NPT and NP_ENABLE is set in VMCB12. The G_PAT consistency check will be addressed separately. As it is now possible for an L1 to run L2 with NP_ENABLE set but ignored, also check that L1 has X86_FEATURE_NPT in nested_npt_enabled(). Pass L1's CR0 to __nested_vmcb_check_controls(). In nested_vmcb_check_controls(), L1's CR0 is available through kvm_read_cr0(), as vcpu->arch.cr0 is not updated to L2's CR0 until later through nested_vmcb02_prepare_save() -> svm_set_cr0(). In svm_set_nested_state(), L1's CR0 is available in the captured save area, as svm_get_nested_state() captures L1's save area when running L2, and L1's CR0 is stashed in VMCB01 on nested VMRUN (in nested_svm_vmrun()).

[PATCH] erspan: Initialize options_len before referencing options.

by Frode Nordahl

The struct ip_tunnel_info has a flexible array member named options that is protected by a counted_by(options_len) attribute. The compiler will use this information to enforce runtime bounds checking deployed by FORTIFY_SOURCE string helpers. As laid out in the GCC documentation, the counter must be initialized before the first reference to the flexible array member. In the normal case the ip_tunnel_info_opts_set() helper is used which would initialize options_len properly, however in the GRE ERSPAN code a partial update is done, preventing the use of the helper function. Before this change the handling of ERSPAN traffic in GRE tunnels would cause a kernel panic when the kernel is compiled with GCC 15+ and having FORTIFY_SOURCE configured: memcpy: detected buffer overflow: 4 byte write of buffer size 0 Call Trace: <IRQ> __fortify_panic+0xd/0xf erspan_rcv.cold+0x68/0x83 ? ip_route_input_slow+0x816/0x9d0 gre_rcv+0x1b2/0x1c0 gre_rcv+0x8e/0x100 ? raw_v4_input+0x2a0/0x2b0 ip_protocol_deliver_rcu+0x1ea/0x210 ip_local_deliver_finish+0x86/0x110 ip_local_deliver+0x65/0x110 ? ip_rcv_finish_core+0xd6/0x360 ip_rcv+0x186/0x1a0 Link: https://gcc.gnu.org/onlinedocs/gcc/Common-Variable-Attributes.html#index-co… Reported-at: https://launchpad.net/bugs/2129580 Fixes: bb5e62f2d547 ("net: Add options as a flexible array to struct ip_tunnel_info") Signed-off-by: Frode Nordahl <fnordahl(a)ubuntu.com> --- net/ipv4/ip_gre.c | 18 ++++++++++++++++-- net/ipv6/ip6_gre.c | 18 ++++++++++++++++-- 2 files changed, 32 insertions(+), 4 deletions(-) diff --git a/net/ipv4/ip_gre.c b/net/ipv4/ip_gre.c index 761a53c6a89a..285a656c9e41 100644 --- a/net/ipv4/ip_gre.c +++ b/net/ipv4/ip_gre.c @@ -330,6 +330,22 @@ static int erspan_rcv(struct sk_buff *skb, struct tnl_ptk_info *tpi, if (!tun_dst) return PACKET_REJECT; + /* The struct ip_tunnel_info has a flexible array member named + * options that is protected by a counted_by(options_len) + * attribute. + * + * The compiler will use this information to enforce runtime bounds + * checking deployed by FORTIFY_SOURCE string helpers. + * + * As laid out in the GCC documentation, the counter must be + * initialized before the first reference to the flexible array + * member. + * + * Link: https://gcc.gnu.org/onlinedocs/gcc/Common-Variable-Attributes.html#index-co… + */ + info = &tun_dst->u.tun_info; + info->options_len = sizeof(*md); + /* skb can be uncloned in __iptunnel_pull_header, so * old pkt_md is no longer valid and we need to reset * it @@ -344,10 +360,8 @@ static int erspan_rcv(struct sk_buff *skb, struct tnl_ptk_info *tpi, memcpy(md2, pkt_md, ver == 1 ?

[PATCH] vfs: fix EBUSY on FSCONFIG_CMD_CREATE retry

by Chen Linxuan via B4 Relay

From: Chen Linxuan <me(a)black-desk.cn> When using fsconfig(..., FSCONFIG_CMD_CREATE, ...), the filesystem context is retrieved from the file descriptor. Since the file structure persists across syscall restarts, the context state is preserved: // fs/fsopen.c SYSCALL_DEFINE5(fsconfig, ...) { ... fc = fd_file(f)->private_data; ... ret = vfs_fsconfig_locked(fc, cmd, &param); ... } In vfs_cmd_create(), the context phase is transitioned to FS_CONTEXT_CREATING before calling vfs_get_tree(): // fs/fsopen.c static int vfs_cmd_create(struct fs_context *fc, bool exclusive) { ... fc->phase = FS_CONTEXT_CREATING; ... ret = vfs_get_tree(fc); ... } However, vfs_get_tree() may return -ERESTARTNOINTR if the filesystem implementation needs to restart the syscall. For example, cgroup v1 does this when it encounters a race condition where the root is dying: // kernel/cgroup/cgroup-v1.c int cgroup1_get_tree(struct fs_context *fc) { ... if (unlikely(ret > 0)) { msleep(10); return restart_syscall(); } return ret; } If the syscall is restarted, fsconfig() is called again and retrieves the *same* fs_context. However, vfs_cmd_create() rejects the call because the phase was left as FS_CONTEXT_CREATING during the first attempt: if (fc->phase != FS_CONTEXT_CREATE_PARAMS) return -EBUSY; Fix this by resetting fc->phase back to FS_CONTEXT_CREATE_PARAMS if vfs_get_tree() returns -ERESTARTNOINTR.

Linux 6.18.1

by Greg Kroah-Hartman

I'm announcing the release of the 6.18.1 kernel. All users of the 6.18 kernel series must upgrade.

[PATCH 5.15.y] mmc: core: use sysfs_emit() instead of sprintf()

by Chen Yu

From: Sergey Shtylyov <s.shtylyov(a)omp.ru> [ Upstream commit f5d8a5fe77ce933f53eb8f2e22bb7a1a2019ea11 ] sprintf() (still used in the MMC core for the sysfs output) is vulnerable to the buffer overflow. Use the new-fangled sysfs_emit() instead. Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool.
