In these # cases the node the LMB exists in may not match the node the device # tree indicates it belongs in. This can lead to a system crash # when trying to DLPAR remove the LMB after a migration or PRRN # event. The current code looks up the node in the device tree to # remove the LMB from, the crash occurs when we try to offline this # node and it does not have any data, i.e. node_data[nid] == NULL. # # 36:mon> e # cpu 0x36: Vector: 300 (Data Access) at [c0000001828b7810] # pc: c00000000036d08c: try_offline_node+0x2c/0x1b0 # lr: c0000000003a14ec: remove_memory+0xbc/0x110 # sp: c0000001828b7a90 # msr: 800000000280b033 # dar: 9a28 # dsisr: 40000000 # current = 0xc0000006329c4c80 # paca = 0xc000000007a55200 softe: 0 irq_happened: 0x01 # pid = 76926, comm = kworker/u320:3 # # 36:mon> t # [link register ] c0000000003a14ec remove_memory+0xbc/0x110 # [c0000001828b7a90] c00000000006a1cc arch_remove_memory+0x9c/0xd0 (unreliable) # [c0000001828b7ad0] c0000000003a14e0 remove_memory+0xb0/0x110 # [c0000001828b7b20] c0000000000c7db4 dlpar_remove_lmb+0x94/0x160 # [c0000001828b7b60] c0000000000c8ef8 dlpar_memory+0x7e8/0xd10 # [c0000001828b7bf0] c0000000000bf828 handle_dlpar_errorlog+0xf8/0x160 # [c0000001828b7c60] c0000000000bf8cc pseries_hp_work_fn+0x3c/0xa0 # [c0000001828b7c90] c000000000128cd8 process_one_work+0x298/0x5a0 # [c0000001828b7d20] c000000000129068 worker_thread+0x88/0x620 # [c0000001828b7dc0] c00000000013223c kthread+0x1ac/0x1c0 # [c0000001828b7e30] c00000000000b45c ret_from_kernel_thread+0x5c/0x80 # # To resolve this we need to track the node a LMB belongs to when # it is added to the system so we can remove it from that node instead # of the node that the device tree indicates it should belong to. # # Signed-off-by: Nathan Fontenot <nfont@linux.vnet.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-gcc --version # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-ld --version # < git log --format=%s --max-count=1 b2d3b5ee66f2a04a918cc043cec0c9ed3de58f40 # < make -s -j 120 ARCH=mips O=/kisskb/build/powerpc-next_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- defconfig # make -s -j 120 ARCH=mips O=/kisskb/build/powerpc-next_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- <stdin>:1478:2: warning: #warning syscall pidfd_send_signal not implemented [-Wcpp] <stdin>:1481:2: warning: #warning syscall io_uring_setup not implemented [-Wcpp] <stdin>:1484:2: warning: #warning syscall io_uring_enter not implemented [-Wcpp] <stdin>:1487:2: warning: #warning syscall io_uring_register not implemented [-Wcpp] <stdin>:1478:2: warning: #warning syscall pidfd_send_signal not implemented [-Wcpp] <stdin>:1481:2: warning: #warning syscall io_uring_setup not implemented [-Wcpp] <stdin>:1484:2: warning: #warning syscall io_uring_enter not implemented [-Wcpp] <stdin>:1487:2: warning: #warning syscall io_uring_register not implemented [-Wcpp] FIT description: Linux 5.1.0-rc3-gb2d3b5ee66f2 Created: Tue Apr 30 01:04:51 2019 Image 0 (kernel@0) Description: Linux 5.1.0-rc3-gb2d3b5ee66f2 Created: Tue Apr 30 01:04:51 2019 Type: Kernel Image Compression: gzip compressed Data Size: 4546659 Bytes = 4440.10 KiB = 4.34 MiB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x80867870 Hash algo: sha1 Hash value: 10312f9d8a531d83dccb58a1a030409a3178b46b Image 1 (fdt@boston) Description: img,boston Device Tree Created: Tue Apr 30 01:04:51 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 3793 Bytes = 3.70 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 4799f50d688573234da6e9d7701234d394759ef4 Image 2 (fdt@ni169445) Description: NI 169445 device tree Created: Tue Apr 30 01:04:51 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 1871 Bytes = 1.83 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 51b89b31605ee62038c8468c429af091dfc75ec7 Image 3 (fdt@xilfpga) Description: MIPSfpga (xilfpga) Device Tree Created: Tue Apr 30 01:04:51 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 2708 Bytes = 2.64 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 63d058b780f65e22da30f0a183433765f1807f1d Default Configuration: 'conf@default' Configuration 0 (conf@default) Description: Generic Linux kernel Kernel: kernel@0 Configuration 1 (conf@boston) Description: Boston Linux kernel Kernel: kernel@0 FDT: fdt@boston Configuration 2 (conf@ni169445) Description: NI 169445 Linux Kernel Kernel: kernel@0 FDT: fdt@ni169445 Configuration 3 (conf@xilfpga) Description: MIPSfpga Linux kernel Kernel: kernel@0 FDT: fdt@xilfpga Completed OK # rm -rf /kisskb/build/powerpc-next_mips-defconfig_mipsel # Build took: 0:01:01.472866
