Thanks Roberto The following changes since commit 026e680b0a08a62b1d948e5a8ca78700bfac0e6e: Merge tag 'pwm/for-6.9-rc3-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux (2024-04-01 14:38:55 -0700) are available in the Git repository at: https://github.com/linux-integrity/linux.git tags/security-mknod-6.9-rc3 for you to fetch changes up to 12d665b7d3fa743ec58160ceda8421d64b63f272: security: Handle dentries without inode in security_path_post_mknod() (2024-04-02 10:01:19 +0200) ---------------------------------------------------------------- Here is a simple follow-up patch for the patch set to move IMA and EVM to the LSM infrastructure. It fixes a kernel panic in the newly introduced function security_path_post_mknod(), when trying to check if an inode is private. The panic occurs because not all dentries have an inode attached to them. I'm sending this PR as IMA/EVM co-maintainer, even if the patch also touches the LSM infrastructure itself (it is acked by Paul).
