Extract nifty FILE_LINE useful for printk style debugging: printk("%s\n", FILE_LINE); It should not be used en mass probably because __FILE__ string literals can be merged while FILE_LINE's won't. But for debugging it is what the doctor ordered. Don't add leading and trailing underscores, they're painful to type. Trust me, I've tried both versions.

With the help of newly changed function parse_crashkernel() and generic reserve_crashkernel_generic(), crashkernel reservation can be simplified by steps: 1) Add a new header file <asm/crash_core.h>, and define CRASH_ALIGN, CRASH_ADDR_LOW_MAX, CRASH_ADDR_HIGH_MAX and DEFAULT_CRASH_KERNEL_LOW_SIZE in <asm/crash_core.h>; 2) Add arch_reserve_crashkernel() to call parse_crashkernel() and reserve_crashkernel_generic(); 3) Add ARCH_HAS_GENERIC_CRASHKERNEL_RESERVATION Kconfig in arch/riscv/Kconfig.

Both crashk_res and crashk_low_res are used to mark the reserved crashkernel regions in iomem_resource tree. And later the generic crashkernel resrvation will be added into crash_core.c. So move crashk_res and crashk_low_res definition into crash_core.c to avoid compiling error if CONFIG_CRASH_CORE=on while CONFIG_KEXEC_CORE is unset. Meanwhile include <asm/crash_core.h> in <linux/crash_core.h> if generic reservation is needed. In that case, <asm/crash_core.h> need be added by ARCH. In asm/crash_core.h, ARCH can provide its own macro definitions to override macros in <linux/crash_core.h> if needed. Wrap the including into CONFIG_ARCH_HAS_GENERIC_CRASHKERNEL_RESERVATION ifdeffery scope to avoid compiling error in other ARCH-es which don't take the generic reservation way yet.

In architecture like x86_64, arm64 and riscv, they have vast virtual address space and usually have huge physical memory RAM. Their crashkernel reservation doesn't have to be limited under 4G RAM, but can be extended to the whole physical memory via crashkernel=,high support. Now add function reserve_crashkernel_generic() to reserve crashkernel memory if users specify any case of kernel pamameters, like crashkernel=xM[@offset] or crashkernel=,high|low. This is preparation to simplify code of crashkernel=,high support in architecutures. Link: https://lkml.kernel.org/r/20230914033142.676708-5-bhe@redhat.comSigned-off-by:

Patch series "kdump: use generic functions to simplify crashkernel reservation in arch", v3. In the current arm64, crashkernel=,high support has been finished after several rounds of posting and careful reviewing. The code in arm64 which parses crashkernel kernel parameters firstly, then reserve memory can be a good example for other ARCH to refer to. Whereas in x86_64, the code mixing crashkernel parameter parsing and memory reserving is twisted, and looks messy. Refactoring the code to make it more readable maintainable is necessary. Here, firstly abstract the crashkernel parameter parsing code into parse_crashkernel() to make it be able to parse crashkernel=,high|low. Then abstract the crashkernel memory reserving code into a generic function reserve_crashkernel_generic(). Finally, in ARCH which crashkernel=,high support is needed, a simple arch_reserve_crashkernel() can be added to call above two functions. This can remove the duplicated implmentation code in each ARCH, like arm64, x86_64 and riscv. crashkernel=512M,high crashkernel=512M,high crashkernel=256M,low crashkernel=512M,high crashkernel=0M,low crashkernel=0M,high crashkernel=256M,low crashkernel=512M crashkernel=512M@0x4f000000 crashkernel=1G-4G:256M,4G-64G:320M,64G-:576M crashkernel=0M This patch (of 9): In all call sites of __parse_crashkernel(), the parameter 'name' is hardcoded as "crashkernel=". So remove the unnecessary parameter 'name', add local varibale 'name' inside __parse_crashkernel() instead.

strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with sysfs_emit(). Direct replacement is safe here since its ok for `kernel_param_ops.get()` to return -errno [3].

In any case, this code does not look right in that the same thread can be accounted twice: taskstats_exit() can account the exiting thread in signal->stats and drop ->siglock but this thread is still on the thread-group list, so lock_task_sighand() can't help.

Use atomic_try_cmpxchg instead of atomic_cmpxchg (*ptr, old, new) == old in panic() and nmi_panic(). x86 CMPXCHG instruction returns success in ZF flag, so this change saves a compare after cmpxchg (and related move instruction in front of cmpxchg). Also, rename cpu variable to this_cpu in nmi_panic() and try to unify logic flow between panic() and nmi_panic(). No functional change intended.

Patch series "kill task_struct->thread_group". This patch (of 2): It could use list_is_singular() but this way it is cheaper. Plus the thread_group_leader() check makes it clear that thread_group_empty() can only return true if p is a group leader. This was not immediately obvious before this patch. task_struct->thread_group no longer has users, it can die.

This relies on fact that group leader is always the 1st entry in the signal->thread_head list.

Patch series "introduce __next_thread(), change next_thread()". After commit dce8f8ed ("document while_each_thread(), change first_tid() to use for_each_thread()") + this series 1. We have only one lockless user of next_thread(), task_group_seq_get_next(). I think it should be changed too. 2. We have only one user of task_struct->thread_group, thread_group_empty(). The next patches will change thread_group_empty() and kill ->thread_group. This patch (of 2): next_tid(start) does: rcu_read_lock(); if (pid_alive(start)) { pos = next_thread(start); if (thread_group_leader(pos)) pos = NULL; else get_task_struct(pos); it should return pos = NULL when next_thread() wraps to the 1st thread in the thread group, group leader, and the thread_group_leader() check tries to detect this case. But this can race with exec. To simplify, suppose we have a main thread M and a single sub-thread T, next_tid(T) should return NULL. Now suppose that T execs. If next_tid(T) is called after T changes the leadership and before it does release_task() which removes the old leader from list, then next_thread() returns M and thread_group_leader(M) = F. Lockless use of next_thread() should be avoided. After this change only task_group_seq_get_next() does this, and I believe it should be changed as well.
