them down. This hack still remains:
* 2. Illegal byte sequences in filenames are handled by treating them as
* single-byte characters with a values of such bytes of the sequence
* cast to wchar_t.
2) Reword the comment in the hack above to reflect implementation.
3) Protect signed wchar_t from sign extension when a signed char is assigned
to it in the hack above.
3) Corresponding backward hack in g_Ctoc() was not implemented, so all
pathes with illegal byte sequences are skipped as result, implement it now.
4) globtilde() forget to convert expanded user home dir from multibyte to
wchar.
5) Protect globtilde() from long expansion truncation.
6) Results was not sorted according to collate as POSIX requires.
If an encrypted install is attempted and fails for any reason, the disk
cannot be erased by the installer because the partition is in use by GELI
At the start of the installation process, all ZFS pools are exported and
all GELI instances are detached, to allow a restarted install to proceed

The pools are exported and reimported in order to write the bootcode
This causes an error when the bootpool is later mounted by common code
The bootpool is now imported with the -N flag to prevent mounting

There seems no hard limit on number of segments per packet in the chip,
and 20 appeared insufficient. Hope 64 will be enough, but if not -- add
check to report that and drop the packet instead of corrupting stack.
when importing collation support from Dragonfly/Illumos amdmi3@ tested the
collation branch and reported an issue with Russian collation. John Marino fixed
the issue in Dragonfly and I merged it back to FreeBSD.
Now that Illumos is working on merging our fixes they (Lauri Tirkkonen) found
issues with the commit that fixes the russian collation in UTF-8 that resulted
in a crash with strxfrm(3) and the ISO-8859-5 locale (fixed in FreeBSD r302916).
This small test was written to ensure we do not bring back the old issue with
russian collation while fixing the other issue.

The vmspace_free() operations might need to lock map, object etc on

done.

The root of the problem here is that TAILQ_FOREACH_FROM will default to
the head of the list if passed NULL, which will be the case if there are
no libraries loaded after this one. Thus all libraries, including the
current, were iterated in that case rather than none.
This was broken in r294373.

r295136 increased the value width from 14 to 32 without the corresponding

ptrace() now stores a mask of optional events in p_ptevents. Currently
this mask is a single integer, but it can be expanded into an array of
integers in the future.
Two new ptrace requests can be used to manipulate the event mask:
PT_GET_EVENT_MASK fetches the current event mask and PT_SET_EVENT_MASK
sets the current event mask.
The current set of events include:
- PTRACE_EXEC: trace calls to execve().
- PTRACE_SCE: trace system call entries.
- PTRACE_SCX: trace syscam call exits.
- PTRACE_FORK: trace forks and auto-attach to new child processes.
- PTRACE_LWP: trace LWP events.
The S_PT_SCX and S_PT_SCE events in the procfs p_stops flags have
been replaced by PTRACE_SCE and PTRACE_SCX. PTRACE_FORK replaces
P_FOLLOW_FORK and PTRACE_LWP replaces P2_LWP_EVENTS.
The PT_FOLLOW_FORK and PT_LWP_EVENTS ptrace requests remain for
compatibility but now simply toggle corresponding flags in the
event mask.
While here, document that PT_SYSCALL, PT_TO_SCE, and PT_TO_SCX both
modify the event mask and continue the traced process.

- Add a sigevent(3) manpage to give a general overview of the sigevent
structure and the available notification mechanisms.
- Document that AIO requests contain a nested sigevent structure that can
be used to request completion notification.
- Expand the sigevent details in other manuals to note details such as
the extra values stored in a queued signal's information or in a posted

This patch add new 'hardening' file responsible for new bsdinstall
'System Hardening' menu allowing users to set some sane and carefully
picked system security options (like random process id's, hiding
other users/groups processes and others).
All options are OFF by default in this patch due to POLA principle
with intention to turn change some of them to ON by default in future.

As was reported on http://seclists.org/oss-sec/2016/q3/68, tmpfs code
contains assertion that rdev != VNOVAL. On FreeBSD, there is no other
consequences except triggering the assert. To be compatible with
systems where device nodes have some significance, reject mknod(2)
call with dev == VNOVAL at the syscall level.
