This is inconsistent since splice()-ing # from/to non-pipe file descriptors does take O_NONBLOCK into # consideration. # # Fix this by promoting O_NONBLOCK, when set on a pipe, to # SPLICE_F_NONBLOCK. # # Some context for how the current implementation of splice() leads to # inconsistent behavior. In the ongoing work[1] to add VM tracing # capability to trace-cmd we stream tracing data over named FIFOs or # vsockets from guests back to the host. # # When we receive SIGINT from user to stop tracing, we set O_NONBLOCK on # the input file descriptor and set SPLICE_F_NONBLOCK for the next call to # splice(). If splice() was blocked waiting on data from the input FIFO, # after SIGINT splice() restarts with the same arguments (no # SPLICE_F_NONBLOCK) and blocks again instead of returning -EAGAIN when no # data is available. # # This differs from the splice() behavior when reading from a vsocket or # when we're doing a traditional read()/write() loop (trace-cmd's # --nosplice argument). # # With this patch applied we get the same behavior in all situations after # setting O_NONBLOCK which also matches the behavior of doing a # read()/write() loop instead of splice(). # # This change does have potential of breaking users who don't expect # EAGAIN from splice() when SPLICE_F_NONBLOCK is not set. OTOH programs # that set O_NONBLOCK and don't anticipate EAGAIN are arguably buggy[2]. # # [1] https://github.com/skaslev/trace-cmd/tree/vsock # [2] https://github.com/torvalds/linux/blob/d47e3da1759230e394096fd742aad423c291ba48/fs/read_write.c#L1425 # # Signed-off-by: Slavomir Kaslev <kaslevs@vmware.com> # Reviewed-by: Steven Rostedt (VMware) <rostedt@goodmis.org> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /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 ee5e001196d1345b8fee25925ff5f1d67936081e # < make -s -j 10 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- randconfig KCONFIG_SEED=0x68EF8B66 WARNING: unmet direct dependencies detected for PINCTRL_IMX_SCU Depends on [n]: PINCTRL [=y] && IMX_SCU [=n] Selected by [y]: - PINCTRL_IMX8QXP [=y] && PINCTRL [=y] && ARCH_MXC [=y] && ARM64 [=y] WARNING: unmet direct dependencies detected for ARM64_ERRATUM_845719 Depends on [n]: COMPAT [=n] Selected by [y]: - ARCH_MXC [=y] WARNING: unmet direct dependencies detected for PINCTRL_IMX_SCU Depends on [n]: PINCTRL [=y] && IMX_SCU [=n] Selected by [y]: - PINCTRL_IMX8QXP [=y] && PINCTRL [=y] && ARCH_MXC [=y] && ARM64 [=y] WARNING: unmet direct dependencies detected for ARM64_ERRATUM_845719 Depends on [n]: COMPAT [=n] Selected by [y]: - ARCH_MXC [=y] # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # yes \n \| make -s -j 10 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 10 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- arch/arm64/Makefile:27: ld does not support --fix-cortex-a53-843419;
