Dave Martin [Catalin Marinas] Add tagged address ABI control prctls (arm64) Add documentation for the the PR_SET_TAGGED_ADDR_CTRL and PR_GET_TAGGED_ADDR_CTRL prctls added in Linux 5.4 for arm64. setns.2 Michael Kerrisk Document the use of PID file descriptors with setns() Starting with Linux 5.8, setns() can take a PID file descriptor as an argument, and move the caller into or more of the namespaces of the thread referred to by that descriptor. capabilities.7 Michael Kerrisk Document CAP_BPF Michael Kerrisk Add CAP_PERFMON symlink.7 Aleksa Sarai Document magic links more completely Changes to individual pages --------------------------- iopl.2 Thomas Piekarski [victorm007@yahoo.com] Updating description of permissions and disabling interrupts Update description of permissions for port-mapped I/O set per-thread and not per-process. Mention that iopl() can not disable interrupts since Linux 5.5 anymore and is in general deprecated and only provided for legacy X servers. See https://bugzilla.kernel.org/show_bug.cgi?id=205317 pidfd_open.2 Michael Kerrisk Add the setns(2) use case for PID file descriptors prctl.2 Michael Kerrisk The parent death signal is cleared on some credential changes See kernel/cred.c::commit_creds() in the Linux 5.6 source code. seccomp.2 Andy Lutomirski Improve x32 and nr truncation notes sync.2 Jeff Layton syncfs() now returns errors if writeback fails capabilities.7 Saikiran Madugula CAP_SYS_RESOURCE: add two more items for POSIX message queues CAP_SYS_RESOURCE also allows overriding /proc/sys/fs/mqueue/msg_max and /proc/sys/fs/mqueue/msgsize_max. ld.so.8 Florian Weimer [Michael Kerrisk] List more places in which dynamic string tokens are expanded This happens for more than just DT_RPATH/DT_RUNPATH.
