[PATCH OLK-6.6] pinctrl: mcp23s08: Fix sleeping in atomic context due to regmap locking
by Pu Lehui 16 Jan '25

16 Jan '25

From: Evgenii Shatokhin <e.shatokhin(a)yadro.com> stable inclusion from stable-v6.6.70 commit 8c6fd5803b988a5e78c9b9e42c70a936d7cfc6ec category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBI4HE CVE: CVE-2024-57889 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a37eecb705f33726f1fb7cd2a67e514a15dfe693 upstream. If a device uses MCP23xxx IO expander to receive IRQs, the following bug can happen: BUG: sleeping function called from invalid context at kernel/locking/mutex.c:283 in_atomic(): 1, irqs_disabled(): 1, non_block: 0, ... preempt_count: 1, expected: 0 ... Call Trace: ... __might_resched+0x104/0x10e __might_sleep+0x3e/0x62 mutex_lock+0x20/0x4c regmap_lock_mutex+0x10/0x18 regmap_update_bits_base+0x2c/0x66 mcp23s08_irq_set_type+0x1ae/0x1d6 __irq_set_trigger+0x56/0x172 __setup_irq+0x1e6/0x646 request_threaded_irq+0xb6/0x160 ... We observed the problem while experimenting with a touchscreen driver which used MCP23017 IO expander (I2C). The regmap in the pinctrl-mcp23s08 driver uses a mutex for protection from concurrent accesses, which is the default for regmaps without .fast_io, .disable_locking, etc. mcp23s08_irq_set_type() calls regmap_update_bits_base(), and the latter locks the mutex. However, __setup_irq() locks desc->lock spinlock before calling these functions. As a result, the system tries to lock the mutex whole holding the spinlock. It seems, the internal regmap locks are not needed in this driver at all. mcp->lock seems to protect the regmap from concurrent accesses already, except, probably, in mcp_pinconf_get/set. mcp23s08_irq_set_type() and mcp23s08_irq_mask/unmask() are called under chip_bus_lock(), which calls mcp23s08_irq_bus_lock(). The latter takes mcp->lock and enables regmap caching, so that the potentially slow I2C accesses are deferred until chip_bus_unlock(). The accesses to the regmap from mcp23s08_probe_one() do not need additional locking. In all remaining places where the regmap is accessed, except mcp_pinconf_get/set(), the driver already takes mcp->lock. This patch adds locking in mcp_pinconf_get/set() and disables internal locking in the regmap config. Among other things, it fixes the sleeping in atomic context described above.

[PATCH OLK-6.6] bpf: Check size for BTF-based ctx access of pointer members
by Tengda Wu 16 Jan '25

16 Jan '25

From: Kumar Kartikeya Dwivedi <memxor(a)gmail.com> stable inclusion from stable-v6.6.67 commit c7e1962a3807d2a9e8c192f23cd3a55794d08f90 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBHYOV Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 659b9ba7cb2d7adb64618b87ddfaa528a143766e upstream. Robert Morris reported the following program type which passes the verifier in [0]: SEC("struct_ops/bpf_cubic_init") void BPF_PROG(bpf_cubic_init, struct sock *sk) { asm volatile("r2 = *(u16*)(r1 + 0)"); // verifier should demand u64 asm volatile("*(u32 *)(r2 +1504) = 0"); // 1280 in some configs } The second line may or may not work, but the first instruction shouldn't pass, as it's a narrow load into the context structure of the struct ops callback. The code falls back to btf_ctx_access to ensure correctness and obtaining the types of pointers. Ensure that the size of the access is correctly checked to be 8 bytes, otherwise the verifier thinks the narrow load obtained a trusted BTF pointer and will permit loads/stores as it sees fit. Perform the check on size after we've verified that the load is for a pointer field, as for scalar values narrow loads are fine. Access to structs passed as arguments to a BPF program are also treated as scalars, therefore no adjustment is needed in their case. Existing verifier selftests are broken by this change, but because they were incorrect. Verifier tests for d_path were performing narrow load into context to obtain path pointer, had this program actually run it would cause a crash. The same holds for verifier_btf_ctx_access tests.
