2025-12-24ecryptfs: Drop redundant NUL terminations after calling ecryptfs_to_hexThorsten Blum2-4/+0
ecryptfs_to_hex() already NUL-terminates the destination buffers. Drop the manual NUL terminations. Signed-off-by: Thorsten Blum <thorsten.blum@linux.dev> Signed-off-by: Tyler Hicks <code@tyhicks.com>
2025-12-24ecryptfs: Replace memcpy + NUL termination in ecryptfs_new_file_contextThorsten Blum1-7/+2
Use strscpy() to copy the NUL-terminated '->global_default_cipher_name' to the destination buffer instead of using memcpy() followed by a manual NUL termination. Remove the now-unused local variable 'cipher_name_len'. Signed-off-by: Thorsten Blum <thorsten.blum@linux.dev> Signed-off-by: Tyler Hicks <code@tyhicks.com>
2025-12-24ecryptfs: Replace strcpy with strscpy in ecryptfs_validate_optionsThorsten Blum1-4/+5
strcpy() has been deprecated [1] because it performs no bounds checking on the destination buffer, which can lead to buffer overflows. Replace it with the safer strscpy().

2025-12-24ecryptfs: Replace strcpy with strscpy in ecryptfs_cipher_code_to_stringThorsten Blum3-5/+12
strcpy() has been deprecated [1] because it performs no bounds checking on the destination buffer, which can lead to buffer overflows. Since the parameter 'char *str' is just a pointer with no size information, extend the function with a 'size' parameter to pass the destination buffer's size as an additional argument. Adjust the call sites accordingly.

2025-12-21scripts: coccicheck: filter *.cocci files by MODESongwei Chai1-1/+5
Enhance the coccicheck script to filter *.cocci files based on the specified MODE (e.g., report, patch). This ensures that only compatible semantic patch files are executed, preventing errors such as: "virtual rule report not supported" This error occurs when a .cocci file does not define a 'virtual <MODE>' rule, yet is executed in that mode. For example: make coccicheck M=drivers/hwtracing/coresight/ MODE=report In this case, running "secs_to_jiffies.cocci" would trigger the error because it lacks support for 'report' mode. With this change, such files are skipped automatically, improving robustness and developer experience.

2025-12-21x86/irqflags: Use ASM_OUTPUT_RM in native_save_fl()Eric Dumazet1-1/+1
clang is generating very inefficient code for native_save_fl() which is used for local_irq_save() in critical spots. Allowing the "pop %0" to use memory: 1) forces the compiler to add annoying stack canaries when CONFIG_STACKPROTECTOR_STRONG=y in many places. 2) Almost always is followed by an immediate "move memory,register" One good example is _raw_spin_lock_irqsave, with 8 extra instructions ffffffff82067a30 <_raw_spin_lock_irqsave>: ffffffff82067a30: ... ffffffff82067a39: 53 push %rbx // Three instructions to ajust the stack, read the per-cpu canary // and copy it to 8(%rsp) ffffffff82067a3a: 48 83 ec 10 sub $0x10,%rsp ffffffff82067a3e: 65 48 8b 05 da 15 45 02 mov %gs:0x24515da(%rip),%rax # <__stack_chk_guard> ffffffff82067a46: 48 89 44 24 08 mov %rax,0x8(%rsp) ffffffff82067a4b: 9c pushf // instead of pop %rbx, compiler uses 2 instructions. ffffffff82067a4c: 8f 04 24 pop (%rsp) ffffffff82067a4f: 48 8b 1c 24 mov (%rsp),%rbx ffffffff82067a53: fa cli ffffffff82067a54: b9 01 00 00 00 mov $0x1,%ecx ffffffff82067a59: 31 c0 xor %eax,%eax ffffffff82067a5b: f0 0f b1 0f lock cmpxchg %ecx,(%rdi) ffffffff82067a5f: 75 1d jne ffffffff82067a7e <_raw_spin_lock_irqsave+0x4e> // three instructions to check the stack canary ffffffff82067a61: 65 48 8b 05 b7 15 45 02 mov %gs:0x24515b7(%rip),%rax # <__stack_chk_guard> ffffffff82067a69: 48 3b 44 24 08 cmp 0x8(%rsp),%rax ffffffff82067a6e: 75 17 jne ffffffff82067a87 ... // One extra instruction to adjust the stack. ffffffff82067a73: 48 83 c4 10 add $0x10,%rsp ... // One more instruction in case the stack was mangled. ffffffff82067a87: e8 a4 35 ff ff call ffffffff8205b030 <__stack_chk_fail> This patch changes nothing for gcc, but for clang saves ~20000 bytes of text even though more functions are inlined. $ size vmlinux.gcc.before vmlinux.gcc.after vmlinux.clang.before vmlinux.clang.after text data bss dec hex filename 45565821 25005462 4704800 75276083 47c9f33 vmlinux.gcc.before 45565821 25005462 4704800 75276083 47c9f33 vmlinux.gcc.after 45121072 24638617 5533040 75292729 47ce039 vmlinux.clang.before 45093887 24638633 5536808 75269328 47c84d0 vmlinux.clang.after $ scripts/bloat-o-meter -t vmlinux.clang.before vmlinux.clang.after add/remove: 1/2 grow/shrink: 21/533 up/down: 2250/-22112 (-19862) Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Uros Bizjak <ubizjak@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Currently AMD IOMMU driver does not reserve domain ids programmed in the DTE while reusing the device table inside kdump kernel. This can cause reallocation of these domain ids for newer domains that are created by the kdump kernel, which can lead to potential IO_PAGE_FAULTs Hence reserve these ids inside pdom_ids.

The current validation 'wire_order[i] > ARRAY_SIZE(config_pins)' allows wire_order[i] to equal ARRAY_SIZE(config_pins), which causes out-of-bounds access when used as index in 'config_pins[wire_order[i]]'. Since config_pins has 4 elements (indices 0-3), the valid range for wire_order should be 0-3. Fix the off-by-one error by using >= instead of > in the validation check.

This causes a warning when perf registers a synthetic event and passes a NULL pointer to the tracepoint register function. Ideally synthetic events should be updated to work with perf, but as that's a feature and not a bug fix, simply now return -ENODEV when perf tries to register an event that has a NULL pointer for its function. This no longer causes a kernel warning and simply causes the perf code to fail with an error message. - Fix 32bit overflow in option flag test The option's flags changed from 32 bits in size to 64 bits in size. Fix one of the places that shift 1 by the option bit number to to be 1ULL. - Fix the output of printing the direct jmp functions The enabled_functions that shows how functions are being attached by ftrace wasn't updated to accommodate the new direct jmp trampolines that set the LSB of the pointer, and outputs garbage.
