With the # first flag-based extension to clone3() making use of the upper 32 bits # of the flag argument we've effectively made it possible for the legacy # clone() syscall to reach clone3() only flags on accident. The sign # extension scenario is just the odd corner-case that we needed to # figure this out. # # The reason we just realized this now and not already when we # introduced CLONE_CLEAR_SIGHAND was that CLONE_INTO_CGROUP assumes that # a valid cgroup file descriptor has been given - whereas # CLONE_CLEAR_SIGHAND doesn't need to verify anything. It just silently # resets the signal handlers to SIG_DFL. # # So the sign extension (or the user accidently passing garbage for the # upper 32 bits) caused the CLONE_INTO_CGROUP bit to be raised and the # kernel to error out when it didn't find a valid cgroup file # descriptor. # # Note, I'm also capping kernel_thread()'s flag argument mainly because # none of the new features make sense for kernel_thread() and we # shouldn't risk them being accidently activated however unlikely. If we # wanted to, we could even make kernel_thread() yell when an unknown # flag has been set which it doesn't do right now. But it's not worth # risking this in a bugfix imho" # # tag 'for-linus-2020-05-13' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: # fork: prevent accidental access to clone3 features # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux-ld --version # < git log --format=%s --max-count=1 8c1684bb81f173543599f1848c29a2a3b1ee5907 # < make -s -j 24 ARCH=nds32 O=/kisskb/build/linus_nds32-allmodconfig_nds32le-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- allmodconfig # < make -s -j 24 ARCH=nds32 O=/kisskb/build/linus_nds32-allmodconfig_nds32le-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- help # make -s -j 24 ARCH=nds32 O=/kisskb/build/linus_nds32-allmodconfig_nds32le-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- olddefconfig # make -s -j 24 ARCH=nds32 O=/kisskb/build/linus_nds32-allmodconfig_nds32le-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/nds32le-linux/bin/nds32le-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] In file included from /kisskb/src/drivers/net/phy/mdio-cavium.c:11: /kisskb/src/drivers/net/phy/mdio-cavium.c: In function 'cavium_mdiobus_set_mode': /kisskb/src/drivers/net/phy/mdio-cavium.h:114:37: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] #define oct_mdio_readq(addr) readq((void )addr) ^ /kisskb/src/drivers/net/phy/mdio-cavium.c:21:16: note: in expansion of macro 'oct_mdio_readq' smi_clk.u64 = oct_mdio_readq(p->register_base + SMI_CLK);
