bugs/riscv: Concatenate 'cond_str' with 'FILE' in __BUG_FLAGS(), to extend WARN_ON/BUG_ON output

2025-07-28T06:06:06Z

Extend WARN_ON and BUG_ON style output from: WARNING: CPU: 0 PID: 0 at kernel/sched/core.c:8511 sched_init+0x20/0x410 to: WARNING: CPU: 0 PID: 0 at [idx < 0 && ptr] kernel/sched/core.c:8511 sched_init+0x20/0x410 Note that the output will be further reorganized later in this series.

riscv/bug: Add ARCH_WARN_ASM macro for BUG/WARN asm code sharing with Rust

2025-07-22T22:04:53Z

Add new ARCH_WARN_ASM macro for BUG/WARN assembly code sharing with Rust to avoid the duplication. No functional changes.

bugs/core: Extend __WARN_FLAGS() with the 'cond_str' parameter

2025-06-13T08:20:52Z

Push the new parameter down into every architecture that defines __WARN_FLAGS(): arm64 loongarch parisc powerpc riscv s390 sh x86 Don't pass anything substantial down yet, just propagate the new parameter with empty strings, without generating it or using it. ( The string is never NULL, so it can be concatenated at the preprocessor level. ) Signed-off-by: Ingo Molnar Acked-by: Peter Zijlstra Cc: Linus Torvalds Cc: linux-arch@vger.kernel.org Link: https://lore.kernel.org/r/20250515124644.2958810-2-mingo@kernel.org

bug: Use normal relative pointers in 'struct bug_entry'

2022-05-19T21:46:10Z

With CONFIG_GENERIC_BUG_RELATIVE_POINTERS, the addr/file relative pointers are calculated weirdly: based on the beginning of the bug_entry struct address, rather than their respective pointer addresses. Make the relative pointers less surprising to both humans and tools by calculating them the normal way.

Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace

2019-07-09T04:48:15Z

Pull force_sig() argument change from Eric Biederman: "A source of error over the years has been that force_sig has taken a task parameter when it is only safe to use force_sig with the current task. The force_sig function is built for delivering synchronous signals such as SIGSEGV where the userspace application caused a synchronous fault (such as a page fault) and the kernel responded with a signal. Because the name force_sig does not make this clear, and because the force_sig takes a task parameter the function force_sig has been abused for sending other kinds of signals over the years. Slowly those have been fixed when the oopses have been tracked down. This set of changes fixes the remaining abusers of force_sig and carefully rips out the task parameter from force_sig and friends making this kind of error almost impossible in the future" * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (27 commits) signal/x86: Move tsk inside of CONFIG_MEMORY_FAILURE in do_sigbus signal: Remove the signal number and task parameters from force_sig_info signal: Factor force_sig_info_to_task out of force_sig_info signal: Generate the siginfo in force_sig signal: Move the computation of force into send_signal and correct it. signal: Properly set TRACE_SIGNAL_LOSE_INFO in __send_signal signal: Remove the task parameter from force_sig_fault signal: Use force_sig_fault_to_task for the two calls that don't deliver to current signal: Explicitly call force_sig_fault on current signal/unicore32: Remove tsk parameter from __do_user_fault signal/arm: Remove tsk parameter from __do_user_fault signal/arm: Remove tsk parameter from ptrace_break signal/nds32: Remove tsk parameter from send_sigtrap signal/riscv: Remove tsk parameter from do_trap signal/sh: Remove tsk parameter from force_sig_info_fault signal/um: Remove task parameter from send_sigtrap signal/x86: Remove task parameter from send_sigtrap signal: Remove task parameter from force_sig_mceerr signal: Remove task parameter from force_sig signal: Remove task parameter from force_sigsegv ...
