This is done through recently # added helpers. # # - Fix a page leak if write_begin() fails. # # - Fix afs_write_begin() to not alter the dirty region info stored in # page->private, but rather do this in afs_write_end() instead when we # know what we actually changed. # # - Fix afs_invalidatepage() to alter the dirty region info on a page # when partial page invalidation occurs so that we don't inadvertantly # include a span of zeros that will get written back if a page gets # laundered due to a remote 3rd-party induced invalidation. # # We mustn't, however, reduce the dirty region if the page has been # seen to be mapped (ie. we got called through the page_mkwrite vector) # as the page might still be mapped and we might lose data if the file # is extended again. # # - Fix the dirty region info to have a lower resolution if the size of # the page is too large for this to be encoded (e.g. powerpc32 with 64K # pages). # # Note that this might not be the ideal way to handle this, since it # may allow some leakage of undirtied zero bytes to the server's copy # in the case of a 3rd-party conflict. # # To aid the last two fixes, two additional changes: # # - Wrap the manipulations of the dirty region info stored in # page->private into helper functions. # # - Alter the encoding of the dirty region so that the region bounds can # be stored with one fewer bit, making a bit available for the # indication of mappedness. # # * tag 'afs-fixes-20201029' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: # afs: Fix dirty-region encoding on ppc32 with 64K pages # afs: Fix afs_invalidatepage to adjust the dirty region # afs: Alter dirty range encoding in page->private # afs: Wrap page->private manipulations in inline functions # afs: Fix where page->private is set during write # afs: Fix page leak on afs_write_begin() failure # afs: Fix to take ref on page when PG_private is set # afs: Fix afs_launder_page to not clear PG_writeback # afs: Fix a use after free in afs_xattr_get_acl() # afs: Fix tracing deref-before-check # afs: Fix copy_file_range() # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 598a597636f8618a0520fd3ccefedaed9e4709b0 # < make -s -j 48 ARCH=arm64 O=/kisskb/build/linus_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- defconfig # < make -s -j 48 ARCH=arm64 O=/kisskb/build/linus_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- help # make -s -j 48 ARCH=arm64 O=/kisskb/build/linus_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- olddefconfig # make -s -j 48 ARCH=arm64 O=/kisskb/build/linus_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:25: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum arch/arm64/Makefile:37: LSE atomics not supported by binutils /kisskb/src/arch/arm64/boot/dts/broadcom/stingray/stingray-usb.dtsi:7.3-14: Warning (dma_ranges_format): /usb:dma-ranges: empty "dma-ranges" property but its #address-cells (1) differs from / (2) /kisskb/src/arch/arm64/boot/dts/broadcom/stingray/stingray-usb.dtsi:7.3-14: Warning (dma_ranges_format): /usb:dma-ranges: empty "dma-ranges" property but its #size-cells (1) differs from / (2) /kisskb/src/arch/arm64/boot/dts/broadcom/stingray/stingray-usb.dtsi:7.3-14: Warning (dma_ranges_format): /usb:dma-ranges: empty "dma-ranges" property but its #address-cells (1) differs from / (2) /kisskb/src/arch/arm64/boot/dts/broadcom/stingray/stingray-usb.dtsi:7.3-14: Warning (dma_ranges_format): /usb:dma-ranges: empty "dma-ranges" property but its #size-cells (1) differs from / (2) /kisskb/src/arch/arm64/boot/dts/broadcom/stingray/stingray-usb.dtsi:7.3-14: Warning (dma_ranges_format): /usb:dma-ranges: empty "dma-ranges" property but its #address-cells (1) differs from / (2) /kisskb/src/arch/arm64/boot/dts/broadcom/stingray/stingray-usb.dtsi:7.3-14: Warning (dma_ranges_format): /usb:dma-ranges: empty "dma-ranges" property but its #size-cells (1) differs from / (2) /kisskb/src/arch/arm64/boot/dts/qcom/ipq6018.dtsi:185.3-14: Warning (dma_ranges_format): /soc:dma-ranges: empty "dma-ranges" property but its #address-cells (1) differs from / (2) /kisskb/src/arch/arm64/boot/dts/qcom/ipq6018.dtsi:185.3-14: Warning (dma_ranges_format): /soc:dma-ranges: empty "dma-ranges" property but its #size-cells (1) differs from / (2) Completed OK # rm -rf /kisskb/build/linus_arm64-defconfig_arm64-gcc5.4 # Build took: 0:05:59.919521
