A quirk of # this interface is that the bind address will only be returned by the # first bind h-call and the subsequent calls will return # 0xFFFF_FFFF_FFFF_FFFF for the bind address. # # We currently do not save the address returned by the first h-call. As a # result we will use the junk address as the base of the bound region if # the hypervisor decides to split the bind across multiple h-calls. This # bug was found when testing with very large SCM volumes where the bind # process would take more time than they hypervisor's internal h-call time # limit would allow. This patch fixes the issue by saving the bind address # from the first call. # # Cc: stable@vger.kernel.org # Fixes: b5beae5e224f ("powerpc/pseries: Add driver for PAPR SCM regions") # Signed-off-by: Oliver O'Halloran <oohall@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 5a3840a470c41ec0b85cd36ca80370330656b163 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_52xx_cm5200_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 52xx/cm5200_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_52xx_cm5200_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:186:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:339:21: note: 'pdeo' was declared here /kisskb/src/drivers/i2c/i2c-core-base.c: In function 'i2c_generic_scl_recovery': /kisskb/src/drivers/i2c/i2c-core-base.c:235:5: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] INFO: Uncompressed kernel (size 0x4e0ca8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-5.0.0-rc1-g5a3840a470c4 Created: Tue Feb 5 22:26:42 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2491608 Bytes = 2433.21 KiB = 2.38 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-fixes_52xx_cm5200_defconfig_powerpc-gcc4.6 # Build took: 0:00:32.611499
