truncated directory for some NFS servers. This turned out to
be because the size of a directory reported by an NFS server
can be smaller that the ufs-like directory created from the
RPC XDR in the client. This patch fixes the problem by changing
r248567 so that vnode_pager_setsize() is only done for regular files.

* Work around kernel bugs that cause a spurious [EINTR] return if a

* Write an error message if an error other than [EINTR] occurs.

with a read lock on the object containing it along with the swhash_mtx.
o Remove some duplicate assertions for swap_pager_freespace() and
swap_pager_unswapped() but keep the object locking references for
documentation.

Make use of Capsicum to protect kdump(1), as it might be used to parse data
from untrusted sources:
- Sandbox kdump(1) using capability mode.
- Limit stdin descriptor (where opened file is moved to) to only
CAP_READ and CAP_FSTAT rights.
- Limit stdout descriptor to only CAP_WRITE, CAP_FSTAT and CAP_IOCTL.
Plus limit allowed ioctls to TIOCGETA only, which is needed for
isatty() to work.
- Limit stderr descriptor to only CAP_WRITE and CAP_FSTAT. In addition
if the -s option is not given, grant CAP_IOCTL right, but allow for
TIOCGWINSZ ioctl only, as we need screen width to dump the data.
- Before entering capability mode call catopen("libc", NL_CAT_LOCALE),
which opens message catalogs and caches data, so that strerror(3)
and strsignal(3) can work in a sandbox.

Rearrange the code so we don't call ioctl(TIOCGWINSZ) if the -s option is given,
as the result won't be used then.

check_deferred_signal() returns twice, since handle_signal() emulates
the return from the normal signal handler by sigreturn(2)ing the
passed context. Second return is performed on the destroyed stack
frame, because __fillcontextx() has already returned. This causes
undefined and bad behaviour, usually the victim thread gets SIGSEGV.
Avoid nested frame and the need to return from it by doing direct call
to getcontext() in the check_deferred_signal() and using a new private
libc helper __fillcontextx2() to complement the context with the
extended CPU state if the deferred signal is still present.
The __fillcontextx() is now unused, but is kept to allow older
libthr.so to be used with the new libc.
Mark __fillcontextx() as returning twice [1].

The selection is made at compile-time, as I still compile a

While testing I out that (at least on my system) lpd has been

code took 120 times more clocktime than calling closefrom().
