8c5a9161d1 Save the last callout function executed on each CPU
Save the last callout function pointer (and its argument) executed
on each CPU for inspection by a debugger.  Add a ddb `show callout_last`
command to show these pointers.  Add a kernel module that I used
for testing that command.

Relocate `ce_migration_cpu` to reduce padding and therefore preserve
the size of `struct callout_cpu` (320 bytes on amd64) despite the
added members.

This should help diagnose reference-after-free bugs where the
callout's mutex has already been freed when `softclock_call_cc`
tries to unlock it.

You might hope that the pointer would still be available, but it
isn't.  The argument to that function is on the stack (because
`softclock_call_cc` uses it later), and that might be enough in
some cases, but even then, it's very laborious.  A pointer to the
callout is saved right before these newly added fields, but that
callout might have been freed.  We still have the pointer to its
associated mutex, and the name within might be enough, but it might
also have been freed.

4db78cacde Remove apparently unused 0-byte files that cause grief on Windows
r235274 added a sort regression test (it operates by comparing output
against GNU sort).  The commit included a number of 0-byte files, one
of which ends in a trailing . which reportedly breaks svn/git checkouts
on Windows.

It appears these were added accidentally, so just remove them.

8a16b7a18f General further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

bae28eaa8d Add a test for the listen queue using two test programs,
listen, and connect.  The listen program is a simple server that
accepts and closes sockets, until a fixed limit, then sets the listen
queue to 0 and counts how many remaining connections it processes.

The connect program repeatedly opens connections and closes them
serving as the driver for the listen program.

Some other highlights:
- Convert the testcases over to ATF
- Don't use hardcoded paths to /tmp (which violate the ATF/kyua samdbox); use
  mkstemp to generate temporary paths for non-SHM_ANON shm objects.

7a37b5fc17 Add a ${CP} alias for copying files in the build.
Some users build FreeBSD as non-root in Perforce workspaces.  By default,
Perforce sets files read-only unless they're explicitly being edited.
As a result, the -f argument must be used to cp in order to override the
read-only flag when copying source files to object directories.  Bare use of
'cp' should be avoided in the future.

Update all current users of 'cp' in the src tree.

0646c22afc Some DTrace tests (mostly in the pid provider directory) make use of
executable ksh scripts. These are currently not copied into the test
directory the way that compiled executables are, so the tests which make use
of them cannot work. This changes the test Makefile to copy the scripts into
the test directory.

0e7ed5d666 Update scripts to work around two sh(1) bugs found in stable/8:
1) _x=$((_x + 1)) does not work while x=$((x + 1)) does.
2) Parameter Expansion, esp. "${x%%bar}" does not work if quoted.

Correct typos and improve some details forwarding.sh already
had in initiator, esp. related to ipfw accepting if the default
is deny.

Add an extra stat call to the "delay" function in addition to the
touch which together is still a lot faster than sleep 1 but seems
to help a lot more to mitigate the unrelated kernel race seen.

d3373029e2 Add regression tests scripts for multi-IP FIBs exercising the send,
receive and forward path tagging packets with both the ifconfig fib
option or using ipfw, running ICMP6, TCP/v6 and UDP/v6 tests and
testing both setfib(2) as well as the SO_SETFIB socket option.

At 16 FIBs a total of over 64k return codes/replies/stati are checked,
sometimes multiple times (in different ways, e.g. the reflected request
as well as ipfw counter values).

The scripts need two or three machines to run and are thus not added
to the tools/regression framework but only to tools/test.

bcf205e1ee - Add two more iconv-related files, which were left out from previous commit
Approved by:	delphij (mentor)
2011-02-25 00:10:26 +00:00
Gabor Kovesdan
ad30f8e79b Add the BSD-licensed Citrus iconv to the base system with default off
setting. It can be built by setting the WITH_ICONV knob. While this
knob is unset, the library part, the binaries, the header file and
the metadata files will not be built or installed so it makes no impact
on the system if left turned off.

This work is based on the iconv implementation in NetBSD but a great
number of improvements and feature additions have been included:

- Some utilities have been added. There is a conversion table generator,
  which can compare conversion tables to reference data generated by
  GNU libiconv. This helps ensuring conversion compatibility.
- UTF-16 surrogate support and some endianness issues have been fixed.
- The rather chaotic Makefiles to build metadata have been refactored
  and cleaned up, now it is easy to read and it is also easier to add
  support for new encodings.
- A bunch of new encodings and encoding aliases have been added.
- Support for 1->2, 1->3 and 1->4 mappings, which is needed for
  transliterating with flying accents as GNU does, like "u.
- Lots of warnings have been fixed, the major part of the code is
  now WARNS=6 clean.
- New section 1 and section 5 manual pages have been added.
- Some GNU-specific calls have been implemented:
  iconvlist(), iconvctl(), iconv_canonicalize(), iconv_open_into()
- Support for GNU's //IGNORE suffix has been added.
- The "-" argument for stdin is now recognized in iconv(1) as per POSIX.
- The Big5 conversion module has been fixed.
- The iconv.h header files is supposed to be compatible with the
  GNU version, i.e. sources should build with base iconv.h and
  GNU libiconv. It also includes a macro magic to deal with the
  char ** and const char ** incompatibility.
- GNU compatibility: "" or "char" means the current local
  encoding in use
- Various cleanups and style(9) fixes.
