2018-06-18Put file descriptors on shared data structures when they are completelyMartin Pieuchot
setup, take 3. LARVAL fd still exist, but they are no longer marked with a flag and no longer reachable via `fd_ofiles[]' or the global linked list. This allows us to simplifies a lot code grabbing new references to fds. All of this is now possible because dup2(2) refuses to clone LARVAL fds. Note that the `fdplock' could now be release in all open(2)-like syscalls, just like it is done in accept(2).

2017-02-09Teach pstat -d to also print untyped kernel symbols.Jeremie Courreges-Anglas
Storage defined in assembly code often doesn't define its type and size, thus the nlist interface can't present it as N_DATA. Instead of fixing all the assembly by adding .type pseudo ops, work around the problem in pstat. Let's hope that allowing N_COMM is sufficient. This makes ''pstat -d u cpuid_level'' useful. Reported by mikeb@, "looks sane" mikeb@ guenther@

2016-09-25Make a move towards ending 4 decades of kernel snooping.Theo de Raadt
Add sysctl kern.allowkmem (default 0) which controls the ability to open /dev/mem or /dev/kmem at securelevel > 0. Over 15 years we converted 99% of utilities in the tree to operate on sysctl-nodes (either by themselves or via code hiding in the guts of -lkvm). pstat -d and -v & procmap are affected and continued use of them will require kern.allowkmem=1 in /etc/sysctl.conf. acpidump (and it's buddy sendbug) are affected, but we'll work out a solution soon. There will be some impact in ports. ok kettenis guenther
2016-09-19Add pledge support to pstatTheo Buehler
The filemode(), ttymode() and vnodemode() functions can be split into two pieces. The *_prep() piece must be hoisted to before pledge and the rest can run under pledge "stdio rpath vminfo". The magic block that decides which ones of the *_prep() pieces must be run with which combination of command line switches is quite impressive. Patch from Rob Pierce, thanks! ok deraadt
2016-09-19Fix pstat -ft. In presence of the -f flag, a logic error in ttymode()Theo Buehler

2016-06-03correct synopsis to make -d usage clearer.Theo de Raadt
The shed fell over because 15 layers of paint exceeded engineering margins.
2016-05-27W^X violations are no longer permitted by default. A kernel log messageTheo de Raadt
is generated, and mprotect/mmap return ENOTSUP. If the sysctl(8) flag kern.wxabort is set then a SIGABRT occurs instead, for gdb use or coredump creation. W^X violating programs can be permitted on a ffs/nfs filesystem-basis, using the "wxallowed" mount option. One day far in the future upstream software developers will understand that W^X violations are a tremendously risky practice and that style of programming will be banished outright. Until then, we recommend most users need to use the wxallowed option on their /usr/local filesystem. At least your other filesystems don't permit such programs. ok jca kettenis mlarkin natano

2016-04-12The -T flag consumes the same data as the -f flag so it requiresTodd C. Miller

2015-08-28Rework the UNIX domain socket garbage collector, including ideas fromPhilip Guenther
{Free,Net}BSD - when a socket is closed with fds in its input, defer closing them to a task to avoid recursing. This eliminates the complicated extra reference taking which had a 37 line(!) comment explanation - move flags, counts, and links only needed for this from struct file to struct unpcb - document the flow of the mark/sweep collector much help from claudio@ who made me explain the GC to him until we trusted it ok claudio@ mpi@ deraadt@

2015-01-16Replace <sys/param.h> with <limits.h> and other less dirty headers whereTheo de Raadt
possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)

2014-11-19delete the KERN_VNODE sysctl. it fails to provide any isolation from theTed Unangst

2014-03-19Pull in FreeBSD r37363 and r37887:Philip Guenther
-- Sync timestamp changes for inodes of special files to disk as late as possible (when the inode is reclaimed). Temporarily only do this if option UFS_LAZYMOD configured and softupdates aren't enabled. UFS_LAZYMOD is intentionally left out of /sys/conf/options. This is mainly to avoid almost useless disk i/o on battery powered machines. It's silly to write to disk (on the next sync or when the inode becomes inactive) just because someone hit a key or something wrote to the screen or /dev/null. -- Made lazy syncing of timestamps for special files non-optional. -- Also, include support in 'pstat -v' to display the IN_LAZYMOD flag. ok tedu@ millert@
