We walk # those bitmaps in chunks of 'unsigned long' in serveral cases, but even # when we don't, we use the regular kernel bitops that are defined to work # on arrays of 'unsigned long', not on some byte array. # # Now, the distinction between arrays of bytes and 'unsigned long' # normally only really ends up being noticeable on big-endian systems, but # Fedor Pchelkin and Alexey Khoroshilov reported that copy_fd_bitmaps() # could be called with an argument that wasn't even a multiple of # BITS_PER_BYTE. And then it fails to do the proper copy even on # little-endian machines. # # The bug wasn't in copy_fd_bitmap(), but in sane_fdtable_size(), which # didn't actually sanitize the fdtable size sufficiently, and never made # sure it had the proper BITS_PER_LONG alignment. # # That's partly because the alignment historically came not from having to # explicitly align things, but simply from previous fdtable sizes, and # from count_open_files(), which counts the file descriptors by walking # them one 'unsigned long' word at a time and thus naturally ends up doing # sizing in the proper 'chunks of unsigned long'. # # But with the introduction of close_range(), we now have an external # source of "this is how many files we want to have", and so # sane_fdtable_size() needs to do a better job. # # This also adds that explicit alignment to alloc_fdtable(), although # there it is mainly just for documentation at a source code level. The # arithmetic we do there to pick a reasonable fdtable size already aligns # the result sufficiently. # # In fact,clang notices that the added ALIGN() in that function doesn't # actually do anything, and does not generate any extra code for it. # # It turns out that gcc ends up confusing itself by combining a previous # constant-sized shift operation with the variable-sized shift operations # in roundup_pow_of_two(). And probably due to that doesn't notice that # the ALIGN() is a no-op. But that's a (tiny) gcc misfeature that doesn't # matter. Having the explicit alignment makes sense, and would actually # matter on a 128-bit architecture if we ever go there. # # This also adds big comments above both functions about how fdtable sizes # have to have that BITS_PER_LONG alignment. # # Fixes: 60997c3d45d9 ("close_range: add CLOSE_RANGE_UNSHARE") # Reported-by: Fedor Pchelkin <aissur0002@gmail.com> # Reported-by: Alexey Khoroshilov <khoroshilov@ispras.ru> # Link: https://lore.kernel.org/all/20220326114009.1690-1-aissur0002@gmail.com/ # Tested-and-acked-by: Christian Brauner <brauner@kernel.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa-linux/bin/hppa-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa-linux/bin/hppa-linux-ld --version # < git log --format=%s --max-count=1 1c24a186398f59c80adb9a967486b65c1423a59d # < make -s -j 10 ARCH=parisc O=/kisskb/build/linus_parisc-allmodconfig_parisc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa-linux/bin/hppa-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # < make -s -j 10 ARCH=parisc O=/kisskb/build/linus_parisc-allmodconfig_parisc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa-linux/bin/hppa-linux- help # make -s -j 10 ARCH=parisc O=/kisskb/build/linus_parisc-allmodconfig_parisc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa-linux/bin/hppa-linux- olddefconfig # make -s -j 10 ARCH=parisc O=/kisskb/build/linus_parisc-allmodconfig_parisc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa-linux/bin/hppa-linux- /kisskb/src/arch/parisc/kernel/vdso32/sigtramp.S: Assembler messages: /kisskb/src/arch/parisc/kernel/vdso32/sigtramp.S:39: Error: unknown pseudo-op: `.proc' /kisskb/src/arch/parisc/kernel/vdso32/sigtramp.S:40: Error: unknown pseudo-op: `.callinfo' /kisskb/src/arch/parisc/kernel/vdso32/sigtramp.S:41: Error: unknown pseudo-op: `.entry' /kisskb/src/arch/parisc/kernel/vdso32/sigtramp.S:44: Error: no such instruction: `ldi 0,%r25' /kisskb/src/arch/parisc/kernel/vdso32/sigtramp.S:45: Error: no such instruction: `ldi 173,%r20' /kisskb/src/arch/parisc/kernel/vdso32/sigtramp.S:46: Error: no such instruction: `ble 0x100(%sr2,%r0)' /kisskb/src/arch/parisc/kernel/vdso32/sigtramp.S:49: Error: no such instruction: `ldi 1,%r25' /kisskb/src/arch/parisc/kernel/vdso32/sigtramp.S:50: Error: no such instruction: `ldi 173,%r20' /kisskb/src/arch/parisc/kernel/vdso32/sigtramp.S:51: Error: no such instruction: `ble 0x100(%sr2,%r0)' /kisskb/src/arch/parisc/kernel/vdso32/sigtramp.S:54: Error: unknown pseudo-op: `.exit' /kisskb/src/arch/parisc/kernel/vdso32/sigtramp.S:55: Error: unknown pseudo-op: `.procend' /kisskb/src/arch/parisc/kernel/vdso32/sigtramp.S:76: Error: unknown pseudo-op: `.stringz' /kisskb/src/arch/parisc/kernel/vdso32/restart_syscall.S: Assembler messages: /kisskb/src/arch/parisc/kernel/vdso32/restart_syscall.S:16: Error: bad or irreducible absolute expression /kisskb/src/arch/parisc/kernel/vdso32/restart_syscall.S:16: Error: junk at end of line, first unrecognized character is `:' /kisskb/src/arch/parisc/kernel/vdso32/restart_syscall.S:26: Error: no such instruction: `ldw 0(%sp),%r31' /kisskb/src/arch/parisc/kernel/vdso32/restart_syscall.S:29: Error: no such instruction: `be 0x100(%sr2,%r0)' /kisskb/src/arch/parisc/kernel/vdso32/restart_syscall.S:30: Error: no such instruction: `ldi 0,%r20' /kisskb/src/arch/parisc/kernel/vdso32/restart_syscall.S:32: Error: .cfi_endproc without corresponding .cfi_startproc make[2]: * [/kisskb/src/arch/parisc/kernel/vdso32/Makefile:34: arch/parisc/kernel/vdso32/sigtramp.o] Error 1 make[2]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/arch/parisc/kernel/vdso32/Makefile:34: arch/parisc/kernel/vdso32/restart_syscall.o] Error 1 make[1]: * [/kisskb/src/arch/parisc/Makefile:177: vdso_prepare] Error 2 make: *** [Makefile:219: __sub-make] Error 2 Command 'make -s -j 10 ARCH=parisc O=/kisskb/build/linus_parisc-allmodconfig_parisc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/hppa-linux/bin/hppa-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/linus_parisc-allmodconfig_parisc-gcc8 # Build took: 0:00:10.114639
