If it # maps to memory, it is considered permanent and should not be deleted, # or bad things can happen. If it is not mapped to memory, then the # user is fine to delete it via rmdir from the instances directory. But # the ref counts assumed 0 was free to remove and greater than zero was # not. But this was not the case. When an instance is created, it # should have the reference of 1, and if it should not be removed, it # must be greater than 1. The boot up code set normal instances with a # ref count of 0, which could get removed if something accessed it and # then released it. And memory mapped instances had a ref count of 1 # which meant it could be deleted, and bad things happen. Keep normal # instances ref count as 1, and set memory mapped instances ref count # to 2. # # - Protect sub buffer size (order) updates from other modifications # # When a ring buffer is changing the size of its sub-buffers, no other # operations should be performed on the ring buffer. That includes # reading it. But the locking only grabbed the buffer->mutex that keeps # some operations from touching the ring buffer. It also must hold the # cpu_buffer->reader_lock as well when updates happen as other paths # use that to do some operations on the ring buffer. # # * tag 'trace-ringbuffer-v6.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: # ring-buffer: Fix reader locking when changing the sub buffer order # ring-buffer: Fix refcount setting of boot mapped buffers # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 2f87d0916ce0d2925cedbc9e8f5d6291ba2ac7b2 # make -s -j 160 ARCH=x86_64 O=/kisskb/build/linus_defconfig_x86_64-gcc8.1 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- defconfig # < make -s -j 160 ARCH=x86_64 O=/kisskb/build/linus_defconfig_x86_64-gcc8.1 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- help # make -s -j 160 ARCH=x86_64 O=/kisskb/build/linus_defconfig_x86_64-gcc8.1 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- olddefconfig # make -s -j 160 ARCH=x86_64 O=/kisskb/build/linus_defconfig_x86_64-gcc8.1 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- Completed OK # rm -rf /kisskb/build/linus_defconfig_x86_64-gcc8.1 # Build took: 0:03:08.576982
