This handle is generally captured at the time the error event was recorded. Due to delays in processing or cascading issues, it may happen that during firmware recovery multiple events are generated. When processing these events in order Linux may already have recovered an affected function making the event information stale. Fix this by doing an unconditional CLP List PCI function retrieving the current function handle with the zdev->state_lock held and ignoring the event if its function handle is stale.

[PATCH v3 0/3] m68k: Bug fix and cleanup for framebuffer debug console

by Finn Thain

This series has a bug fix for the early bootconsole as well as some related efficiency improvements and cleanup. The relevant code is subject to CONSOLE_DEBUG, which is presently only used with CONFIG_MAC. To test this series (in qemu-system-m68k, for example) it's helpful to enable CONFIG_EARLY_PRINTK and CONFIG_FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER and boot with kernel parameters 'console=ttyS0 earlyprintk keep_bootcon'. --- Changed since v1: - Solved problem with line wrap while scrolling. - Added two additional patches. Changed since v2: - Adopted addq and subq as suggested by Andreas. Finn Thain (3): m68k: Fix lost column on framebuffer debug console m68k: Avoid pointless recursion in debug console rendering m68k: Remove unused "cursor home" code from debug console arch/m68k/kernel/head.S | 73 +++++++++++++++++++++-------------------- 1 file changed, 37 insertions(+), 36 deletions(-) -- 2.45.3

[PATCH 6.15.y v2] mm/vmalloc: fix data race in show_numa_info()

by Jeongjun Park

commit 5c5f0468d172ddec2e333d738d2a1f85402cf0bc upstream. The following data-race was found in show_numa_info(): ================================================================== BUG: KCSAN: data-race in vmalloc_info_show / vmalloc_info_show read to 0xffff88800971fe30 of 4 bytes by task 8289 on cpu 0: show_numa_info mm/vmalloc.c:4936 [inline] vmalloc_info_show+0x5a8/0x7e0 mm/vmalloc.c:5016 seq_read_iter+0x373/0xb40 fs/seq_file.c:230 proc_reg_read_iter+0x11e/0x170 fs/proc/inode.c:299 .... write to 0xffff88800971fe30 of 4 bytes by task 8287 on cpu 1: show_numa_info mm/vmalloc.c:4934 [inline] vmalloc_info_show+0x38f/0x7e0 mm/vmalloc.c:5016 seq_read_iter+0x373/0xb40 fs/seq_file.c:230 proc_reg_read_iter+0x11e/0x170 fs/proc/inode.c:299 .... value changed: 0x0000008f -> 0x00000000 ================================================================== According to this report,there is a read/write data-race because m->private is accessible to multiple CPUs. To fix this, instead of allocating the heap in proc_vmalloc_init() and passing the heap address to m->private, vmalloc_info_show() should allocate the heap.
