EINJ parameter support is only usable for some specific BIOS. Originally, it is expected to have no harm for BIOS does not support it. But now, we found it will cause issue (memory overwriting) for some BIOS. So param support is disabled by default and only enabled when newly added module parameter named "param_extension" is explicitly specified. Signed-off-by:

memory_failure() is the entry point for HWPoison memory error recovery. It must be called in process context. But commonly hardware memory errors are notified via MCE or NMI, so some delayed execution mechanism must be used. In MCE handler, a work queue + ring buffer mechanism is used. In addition to MCE, now APEI (ACPI Platform Error Interface) GHES (Generic Hardware Error Source) can be used to report memory errors too. To add support to APEI GHES memory recovery, a mechanism similar to that of MCE is implemented. memory_failure_queue() is the new entry point that can be called in IRQ context. The next step is to make MCE handler uses this interface too. Signed-off-by:

printk is used by GHES to report hardware errors. Ratelimit is enforced on the printk to avoid too many hardware error reports in kernel log. Because there may be thousands or even millions of corrected hardware errors during system running. Currently, a simple scheme is used. That is, the total number of hardware error reporting is ratelimited. This may cause some issues in practice. For example, there are two kinds of hardware errors occurred in system. One is corrected memory error, because the fault memory address is accessed frequently, there may be hundreds error report per-second. The other is corrected PCIe AER error, it will be reported once per-second. Because they share one ratelimit control structure, it is highly possible that only memory error is reported. To avoid the above issue, an error record content based throttle algorithm is implemented in the patch. Where after the first successful reporting, all error records that are same are throttled for some time, to let other kinds of error records have the opportunity to be reported. In above example, the memory errors will be throttled for some time, after being printked. Then the PCIe AER error will be printked successfully. Signed-off-by:

Some APEI GHES recoverable errors are reported via NMI, but printk is not safe in NMI context. To solve the issue, a lock-less memory allocator is used to allocate memory in NMI handler, save the error record into the allocated memory, put the error record into a lock-less list. On the other hand, an irq_work is used to delay the operation from NMI context to IRQ context. The irq_work IRQ handler will remove nodes from lock-less list, printk the error record and do some further processing include recovery operation, then free the memory. Signed-off-by:

This version of the gen_pool memory allocator supports lockless operation. This makes it safe to use in NMI handlers and other special unblockable contexts that could otherwise deadlock on locks. This is implemented by using atomic operations and retries on any conflicts. The disadvantage is that there may be livelocks in extreme cases. For better scalability, one gen_pool allocator can be used for each CPU. The lockless operation only works if there is enough memory available. If new memory is added to the pool a lock has to be still taken. So any user relying on locklessness has to ensure that sufficient memory is preallocated. The basic atomic operation of this allocator is cmpxchg on long. On architectures that don't have NMI-safe cmpxchg implementation, the allocator can NOT be used in NMI handler. So code uses the allocator in NMI handler should depend on CONFIG_ARCH_HAVE_NMI_SAFE_CMPXCHG. Signed-off-by:

Huang Ying authored
Cmpxchg is used to implement adding new entry to the list, deleting all entries from the list, deleting first entry of the list and some other operations. Because this is a single list, so the tail can not be accessed in O(1). If there are multiple producers and multiple consumers, llist_add can be used in producers and llist_del_all can be used in consumers. They can work simultaneously without lock. But llist_del_first can not be used here. Because llist_del_first depends on list->first->next does not changed if list->first is not changed during its operation, but llist_del_first, llist_add, llist_add (or llist_del_all, llist_add, llist_add) sequence in another consumer may violate that. If there are multiple producers and one consumer, llist_add can be used in producers and llist_del_all or llist_del_first can be used in the consumer. This can be summarized as follow: | add | del_first | del_all add | - | - | - del_first | | L | L del_all | | | - Where "-" stands for no lock is needed, while "L" stands for lock is needed. The list entries deleted via llist_del_all can be traversed with traversing function such as llist_for_each etc. But the list entries can not be traversed safely before deleted from the list. The order of deleted entries is from the newest to the oldest added one. If you want to traverse from the oldest to the newest, you must reverse the order by yourself before traversing. The basic atomic operation of this list is cmpxchg on long. On architectures that don't have NMI-safe cmpxchg implementation, the list can NOT be used in NMI handler. So code uses the list in NMI handler should depend on CONFIG_ARCH_HAVE_NMI_SAFE_CMPXCHG. Signed-off-by:

Huang Ying authored
cmpxchg() is widely used by lockless code, including NMI-safe lockless code. But on some architectures, the cmpxchg() implementation is not NMI-safe, on these architectures the lockless code may need a spin_trylock_irqsave() based implementation. This patch adds a Kconfig option: ARCH_HAVE_NMI_SAFE_CMPXCHG, so that NMI-safe lockless code can depend on it or provide different implementation according to it. On many architectures, cmpxchg is only NMI-safe for several specific operand sizes. So, ARCH_HAVE_NMI_SAFE_CMPXCHG define in this patch only guarantees cmpxchg is NMI-safe for sizeof(unsigned long).

exit_mm() sets ->mm == NULL then it does mmput()->exit_mmap() which frees the memory. However select_bad_process() checks ->mm != NULL before TIF_MEMDIE, so it continues to kill other tasks even if we have the oom-killed task freeing its memory. Change select_bad_process() to check ->mm after TIF_MEMDIE, but skip the tasks which have already passed exit_notify() to ensure a zombie with TIF_MEMDIE set can't block oom-killer. Alternatively we could probably clear TIF_MEMDIE after exit_mmap(). Signed-off-by:

The first packet that gdb sends when the kernel is in kdb mode seems to change with every release of gdb. Instead of continuing to add many different gdb packets, change kdb to automatically look for any thing that looks like a gdb packet. Example 1 cold start test: echo g > /proc/sysrq-trigger $D#44+ Example 2 cold start test: echo g > /proc/sysrq-trigger $3#33 The second one should re-enter kdb's shell right away and is purely a test.

When switching from kdb mode to kgdb mode packets were getting lost depending on the size of the fifo queue of the serial chip. When gdb initially connects if it is in kdb mode it should entirely send any character buffer over to the gdbstub when switching connections. Previously kdb was zero'ing out the character buffer and this could lead to gdb failing to connect at all, or a lengthy pause could occur on the initial connect. Signed-off-by:
