Today /proc/#/ctl offers a narrow subset of ptrace(2) commands and is not applicable for modern applications use beyond simplistic tracing scenarios. This removal will simplify kernel internals. Users will still be able to use all the other /proc files. This change won't affect other procfs files neither Linux compat features within mount_procfs(8). /proc/#/ctl isn't available on Linux. Remove: - /proc/#/ctl from mount_procfs(8) - P_FSTRACE note from the documentation of ps(1) - /proc/#/ctl and filesystem tracing documentation from mount_procfs(8) - KAUTH_REQ_PROCESS_PROCFS_CTL documentation from kauth(9) - source code file miscfs/procfs/procfs_ctl.c - PFSctl and procfs_doctl() from sys/miscfs/procfs/procfs.h - KAUTH_REQ_PROCESS_PROCFS_CTL from sys/sys/kauth.h - PSL_FSTRACE (0x00010000) from sys/sys/proc.h - P_FSTRACE (0x00010000) from sys/sys/sysctl.h Reduce code complexity after removal of this functionality. Update TODO.ptrace accordingly: remove two entries about /proc tracing. Do not keep legacy notes as comments in the headers about removed PSL_FSTRACE / P_FSTRACE, as this interface had little number of users (close or equal to zero). Proposed on tech-kern@@. All filesystem tracing utility users are encouraged to switch to ptrace(2).

Remove the filesystem tracing feature This is a legacy interface from 4.4BSD, and it was introduced to overcome shortcomings of ptrace(2) at that time, which are no longer relevant (performance). Today /proc/#/ctl offers a narrow subset of ptrace(2) commands and is not applicable for modern applications use beyond simplistic tracing scenarios. This removal will simplify kernel internals. Users will still be able to use all the other /proc files. This change won't affect other procfs files neither Linux compat features within mount_procfs(8). /proc/#/ctl isn't available on Linux. Remove: - /proc/#/ctl from mount_procfs(8) - P_FSTRACE note from the documentation of ps(1) - /proc/#/ctl and filesystem tracing documentation from mount_procfs(8) - KAUTH_REQ_PROCESS_PROCFS_CTL documentation from kauth(9) - source code file miscfs/procfs/procfs_ctl.c - PFSctl and procfs_doctl() from sys/miscfs/procfs/procfs.h - KAUTH_REQ_PROCESS_PROCFS_CTL from sys/sys/kauth.h - PSL_FSTRACE (0x00010000) from sys/sys/proc.h - P_FSTRACE (0x00010000) from sys/sys/sysctl.h Reduce code complexity after removal of this functionality. Update TODO.ptrace accordingly: remove two entries about /proc tracing. Do not keep legacy notes as comments in the headers about removed PSL_FSTRACE / P_FSTRACE, as this interface had little number of users (close or equal to zero). Proposed on tech-kern@@. All filesystem tracing utility users are encouraged to switch to ptrace(2). Sponsored by untangle the mess: - factor out common code - break each ptrace subcall to its own sub-function .. more to come ... - reduce ifdef ugliness by moving it up top. - factor out PT_IO and make PT_{READ,WRITE}_{I,D} use it - factor out PT_DUMPCORE - factor out sendsig code .. more to come ... handle siginfo requests for ptrace32 ptrace: Partially undo PT_{READ,WRITE}_{I,D} and unbreak these commands The refactored code did not work and was generating EFAULT. Sponsored by Merge the code back; the problem was that since we are reading/writing to a kernel address for PT_{READ,WRITE}_{I,D} we need the kernel vmspace. provide separate read and write functions to accomodate register functions that need a size argument. don't ignore error from copyout_piod Use the proper process (the tracee) to get information about lwps and registers and the tracer for vmspace. Add new sysctl(3) entry: security.models.extensions.user_set_dbregs Model this new sysctl(3) entry after "user_set_cpu_affinity" in the same level of sysctl(3) switches. Allow to read unconditionally Debug Registers (no change here). This is convenient as even if a user of a debugger does not use hardware assisted watchpoints/breakpoints, a debugger can still prompt these values to store in an internal cache with context of registers. Reading them should have no security concerns. Add a paranoid MI switch that prohibits by default setting these registers by a regular user (non-superuser). Make this switch disabled by default. There are enough reserved bits out there to allow using them unconditionally on hardened hosts. Features shipped with Debug Registers are optional features in debuggers. There is no reduction in elementary functionality.
