csky: uaccess.h: Coding convention with asm generic

2021-04-28T15:02:23Z

Using asm-generic/uaccess.h to prevent duplicated code: - Add user_addr_max which mentioned in generic uaccess.h - Remove custom definitions of KERNEL/USER_DS, get/set_fs, uaccess_kerenl - Using generic extable.h instead of custom definitions in uaccess.h Change v2: - Fixup tinyconfig compile error, "__put_user_bad" - Add __get_user_asm_64 Signed-off-by: Guo Ren Link: https://lore.kernel.org/linux-csky/CAK8P3a1DvsXSEDoovLk11hzNHyJi7vqNoToU+n5aFi2viZO_Uw@mail.gmail.com/T/#mbcd58a0e3450e5598974116b607589afa16a3ab7 Cc: Arnd Bergmann

local64.h: make mandatory

2020-12-29T23:36:49Z

Make mandatory in include/asm-generic/Kbuild and remove all arch/*/include/asm/local64.h arch-specific files since they only #include . This fixes build errors on arch/c6x/ and arch/nios2/ for block/blk-iocost.c. Build-tested on 21 of 25 arch-es. (tools problems on the others) Yes, we could even rename to and change all #includes to use instead.

csky: Enable seccomp architecture tracking

2020-11-20T19:16:34Z

To enable seccomp constant action bitmaps, we need to have a static mapping to the audit architecture and system call table size. Add these for csky.

csky: Add SECCOMP_FILTER supported

2020-07-31T01:51:05Z

secure_computing() is called first in syscall_trace_enter() so that a system call will be aborted quickly without doing succeeding syscall tracing if seccomp rules want to deny that system call.

asm-generic: make more kernel-space headers mandatory

2020-04-02T16:35:25Z

Change a header to mandatory-y if both of the following are met: [1] At least one architecture (except um) specifies it as generic-y in arch/*/include/asm/Kbuild [2] Every architecture (except um) either has its own implementation (arch/*/include/asm/*.h) or specifies it as generic-y in arch/*/include/asm/Kbuild This commit was generated by the following shell script. ----------------------------------->8----------------------------------- arches=$(cd arch; ls -1 | sed -e '/Kconfig/d' -e '/um/d') tmpfile=$(mktemp) grep "^mandatory-y +=" include/asm-generic/Kbuild > $tmpfile find arch -path 'arch/*/include/asm/Kbuild' | xargs sed -n 's/^generic-y += $.*$/\1/p' | sort -u | while read header do mandatory=yes for arch in $arches do if ! grep -q "generic-y += $header" arch/$arch/include/asm/Kbuild && ! [ -f arch/$arch/include/asm/$header ]; then mandatory=no break fi done if [ "$mandatory" = yes ]; then echo "mandatory-y += $header" >> $tmpfile for arch in $arches do sed -i "/generic-y += $header/d" arch/$arch/include/asm/Kbuild done fi done sed -i '/^mandatory-y +=/d' include/asm-generic/Kbuild LANG=C sort $tmpfile >> include/asm-generic/Kbuild ----------------------------------->8----------------------------------- One obvious benefit is the diff stat: 25 files changed, 52 insertions(+), 557 deletions(-) It is tedious to list generic-y for each arch that needs it. So, mandatory-y works like a fallback default (by just wrapping asm-generic one) when arch does not have a specific header implementation. See the following commits: def3f7cefe4e81c296090e1722a76551142c227c a1b39bae16a62ce4aae02d958224f19316d98b24 It is tedious to convert headers one by one, so I processed by a shell script.

asm-generic: Make dma-contiguous.h a mandatory include/asm header

2020-02-04T10:38:59Z

dma-continuguous.h is generic for all architectures except arm32 which has its own version.

arch: remove dangling asm-generic wrappers

2019-05-18T02:49:52Z

These generic-y defines do not have the corresponding generic header in include/asm-generic/, so they are definitely invalid. Signed-off-by: Masahiro Yamada
