	[n+obsd] fix syntax error
	 Corrected end of comment.
	 This change closes #138.
	 @albert-github reported this issue in #138,
	 and provided the fix in #140
	Don't ignore failures in test/Makefile
	 Tobias Geerinckx-Rice <me@tobias.gr> provides the fix.
	Update perl scripts for the past few decades of progress
	 Generally, perl is available on base systems - people who are manually
	 installing perl into /usr/local/bin are the exception rather than the
	 rule. In addition, Perl 5 was release in 1994, so Perl 4 isn't relevant
	 any more. We've also standardized on the .pl extension, rather than
	 .perl5 or whatever.
	 Provided by @dilinger (Andres Salomon) in #149.
	 A commit in the pull request includes work of Nicholas Bamber.
	Drop LSOF_CCDATE across all dialects to ensure reproducible builds
	 Simplify things for reproducible builds by just getting rid of
	 the embedded date/time string. With LSOF_CCDATE gone, keeping
	 SOURCE_DATE_EPOCH around doesn't make much sense, so drop that as
	 well. Folks doing reproducible builds should still override the
	 LSOF_HOST, LSOF_LOGNAME, LSOF_SYSINFO, and LSOF_USER variables (as
	 they were previously doing before SOURCE_DATE_EPOCH).
	 Provided by @dilinger (Andres Salomon) in #150.
	[FreeBSD] get the ISO9660 filesystem working again
	 The ISO9660 filesystem broke starting with FreeBSD 7 due to the header
	 location changing. Fix the header search path to get it to be detected
	 again. Fix the header inclusion order. Also add the new way of finding
	 dev_t on more recent FreeBSD versions.
	 Provided by Damjan Jovanovic in #151.
	[FreeBSD] add support for msdosfs on FreeBSD
	 Provided by Damjan Jovanovic in #151.
	Fix FD field description.
	 In 811dc78 the output format was changed to not printf the `f`
	 field by default, however the field description in `lsof_fields.h`,
	 as seen in `-F?` output still included the `(always selected)` text.
	 Provided by @algorythmic (Grisha Levit) in #158.
	Adjust alignment of buffer passed to stat().
	 The original code passes char[] buffer to stat(). This can be cause
	 a SIGBUS. #160 reported an actual crash on armv7a + glibc-2.33 platform.
	 See also https://sourceware.org/bugzilla/show_bug.cgi?id=27993.
	 Reported by @10ne1 in #160.
	Clean up source code and documentats.
	 - remove trailing whitespace,
	 - fix some issues in scripts found through shellcheck, and
	 - fix spelling
	 Provided by @a1346054 in #163.
	man page: fix hyphen issues
	 Properly use '-' and '\-' in the man page, ensuring that users
	 can cut & paste commandline options without issue. Original
	 patch from Raoul Gunnar Borenius <borenius@dfn.de>, and
	 submitted/expanded by @dilinger (Andres Salomon) in #168.
	[FreeBSD] update for FreeBSD 13 & 14, and various internal changes
	 submitted by @DmitryAndric & @emaste.
	[FreeBSD] remove various old FreeBSD versions from support
	 submitted by @emaste
	[FreeBSD] configure: suggest variable to set if FreeBSD sys not
	 found
	 submitted by @emaste
	Fix broken LSOF_CFLAGS_OVERRIDE.
	 Provided by Fabrice Fontaine in #172.
	[linux] Remove sysvlegacy function.
	 Provided by Fabrice Fontaine in #195.
	[linux] use close_range instead of calling close repeatedly
	 At the starting up, lsof closes its file descriptors greater
	 than 2 by calling close(2) repeatedly. As reported in #186,
	 it can take long time. Linux 5.9 introduced close_range(2).
	The new system call can close multiple file descriptors faster.
	 @qianzhangyl reported the original issue (#186).
	Add -Q option for adjusting exit status when failed to find a
	 search item (#129)
	In the original code, lsof returned 1 when it failed to find a
	 search item. With the new option, lsof returns 0 in the case.
	Document -Q option in manpage/00QUICKSTART, and adjust -h
	 output by @dilinger (Andres Salomon) in #129.
	Improve readability of complex adverbial clause by adding a
	 comma.
	Provided by Danny Fowler in #156.
   lsof-4.94.0-linux
	(All changes in this version are ported from
	 lsof-org/lsof-linux repository at GitHub).
	Introduced a new test harness. The harness can run
	 test cases specific to a dialect. It is designed for
	 running test cases on CI environment like Travis-CI.
	 However, it is runnable locally with following command
	 line:
		$ ./check.sh DIALECT
	 after making lsof executable.
	[linux] Fixed a bug +|-E options output for pipe.
	 If two processes use the same fd number for a pipe
	 connecting them, the option didn't print the
	 information about it.
	[linux] Fixed a bug +|-E options output for PTY.
	 If two processes use the same fd number for a PTY
	 connecting them, the option didn't print the
	 information about it.
	[linux] Fixed a bug +|-E options output for PTY.
	 The code for detecting a slave device was incorrect.
	[linux] Fixed a potential bug +|-E options output for
	 PTY. A structure field for the feature was not
	 initialized.
	[linux] Added a code for decoding O_PATH flag in +fg
	 option.
	[linux] Added a code for decoding O_CLOEXEC flag as CX
	 in +fg option.
	[linux] Added a code for decoding O_TMPFILE flag as
	 TMPF in +fg option.
	[linux] Added Linux display of INET socket endpoint
	 information with +|-E option. The option handles
	 INET sockets using IPC.
	[linux] Added support for POSIX MQ of Linux
	 implementation.  A POSIX message queue (MQ) is
	 represented in a fd on Linux.  lsof reported it as a
	 regular file. lsof with this change reports it as a
	 file with PSXMQ type if mqueue file system is mounted.
	[linux] Added Linux display of POSIX message queue
	 endpoint information with +|-E option. mqueue file system
	 must be mounted to display the information.
	[linux] Added Linux display of INET6 socket endpoint
	 information with +|-E option. The option handles
	 INET6 sockets using IPC.
	[FreeBSD] update to include <sys/_lock.h> on recent -CURRENT
	 since it is no longer implicitly included via header pollution.
	[linux] Added Linux display of eventfd endpoint information
	 with +|-E option. The option handles eventfd using IPC.
	[FreeBSD] include <stdbool.h> for recent change requiring
	 refcount(9).
	Enhanced -r option. With `c<N>' specifier, lsof can stop itself
	 when the number of iterations reaches at <N>.
	[linux] Fixed accessing an uninitialized local variable.
	 Detected by valgrind.
	[linux] fix a crash when printing the endpoint for unaccepted
	 unix socket with +E option.
	 This closes the github issue #74 reported by @jolmg.
	[linux] abort execution when failing in memory allocation for
	 socket private data.
	[linux] decode the name of DCCP socket type.
	[linux] decode more netlink protocol numbers (RDMA, CRYPTO, and
	 SMC).
	[linux] print the connection state of unix domain socket
	 Lsof can print the state of TCP socket like:
		 nc      22247 yamato    3u  IPv4 471409      0t0        TCP localhost:38802->localhost:9999 (ESTABLISHED)
	 This change exnteds this feature to support unix domain sockets.
	 LISTEN, UNCONNECTED, CONNECTING, CONNECTED, DISCONNECTING,
	 and UNKNOWN can be taken as a state.
	 An example of output:
		 evince    17333  yamato    1u  unix 0x0000000054183795      0t0  89141 type=STREAM (CONNECTED)
	 This feature is enabled by default.
	 To turn off printing state information, use -T option.
	 Don't display command usage even when a file (or directory) listed
	 in command line doesn't exist.
	 This closes the github issue #90 reported by @rowlap.
	[FreeBSD] merge all the FreeBSD specific fixes from the FreeBSD sysutils/lsof port
	[linux] allow reproducible builds
	 In a reproducible build all varied information is removed.  This
	 change does so, by checking if the standard SOURCE_DATE_EPOCH
	 variable is set.  If it is, we are attempting a reproducible build
	 and will strip varying information.
	 About the standard, see https://reproducible-builds.org/specs/source-date-epoch/
	 Provided in github pull request #93 by @T4cC0re.
	[freebsd] update for r363214
	 - no user visible changes
	Added the way to include (or exclude) all numbered file descriptors
	 in -d option. "fd" is a pseudo file descriptor name for the purpose.
	 See the following output on Linux; lsof doesn't print cwd, rtd, txt,
	 and mem files.
	  # ./lsof -p $$ -a -d fd
	  COMMAND    PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
	  bash    866421 root    0u   CHR  136,1      0t0    4 /dev/pts/1

	 The change is provided by Henry Peteet.
	[linux] handle ffff:ffff in ipv6 addr correctly
	 The listen address and port of an AF_INET6 socket were not display if
	 the socket listened at an ipv6 address including ffff:ffff.
	 Here is a command session demonstrating the bug:
	    # ip -6 addr add abcd:ef10:ffff:ffff:ffff:ffff:ffff:ff62 dev lo
	    # nc -6      -l  abcd:ef10:ffff:ffff:ffff:ffff:ffff:ff62 8888 &
	    [1] 6762
	    # ./lsof -p 6762 -a -d fd -P -n
	    COMMAND  PID   USER   FD   TYPE DEVICE SIZE/OFF    NODE NAME
	    nc      6762 yamato    0u   CHR  136,6      0t0       9 /dev/pts/6
	    nc      6762 yamato    1u   CHR  136,6      0t0       9 /dev/pts/6
	    nc      6762 yamato    2u   CHR  136,6      0t0       9 /dev/pts/6
	    nc      6762 yamato    3u  sock    0,9      0t0 5833594 protocol: TCPv6
	 The last line should be:
	    nc      6762 yamato    3u  IPv6 5833594      0t0  TCP [abcd:ef10:ffff:ffff:ffff:ffff:ffff:ff62]:8888 (LISTEN)
	 The original code decoding an ipv6 address uses UINT32_MAX constant
	 incorrect way.
	 @zhrf2020 reported this bug in #102.
	 @zhrf2020 provided the initial version of fix, #109.
	man page,[linux]: enumerate abbreviated flags printed with '+f g' option
	Make -Fo option work
	 -Fo option is for printing file offset. For regular files,
	 the option didn't work.
	 Here is a command session demonstrating the fix:
	    # ./lsof -Fo -o0| grep ^o | sort | uniq -c
	    90586 o0t0
	       87 o0t101
	       84 o0t103
	 ...
	 @JustAnotherArchivist reported this bug in #118.
	 man page: fix definition of the `o` field on programmatic output
	 The change is provided by @JustAnotherArchivist who reported
	 the original issue in #118.
	[linux]: show the pid monitored by a pidfd
	 With this change, lsof prints pidfd in the following form:
	    [pidfd:%d]
	 where %d represents the pid monitored by the pidfd.
	 Example output:
	    # ./lsof -p 12573 -p 12710 | grep pidfd
	    dbus-brok 12573  jet   11u  a_inode               0,13         0     13312 [pidfd:12575]
	    dbus-brok 12710  jet   10u  a_inode               0,13         0     13312 [pidfd:12711]
	 fd 11 of pid 12573 monitors pid 12575.
	 fd 10 of pid 12710 monitors pid 12711.
	 This change closed #116.
	 Don't select the file descriptor field by default.
	 The version 4.88 introduced the change for selecting the file
	 descriptor field by default. However, the change is not
	 suitable for users who wants to print only PID field.
	 @po5857 suggests the use case and the way to improve the man page.
	[linux]: enumerate fds monitored by an eventpoll fd
	 With this change, lsof prints an eventpoll fd in the following form:
	    [eventpoll:<fd0>,<fd1>,...,<fdn>...]
	 Here fdX is a file descriptor monitored by the eventpoll fd.
	 If an eventpoll fd monitors too many file descriptors, lsof
	 truncates the list of fds. "..." at the end of list implies
	 the truncation.
	 Example output:
		# sudo ./lsof -p 1 -a -d 10,11,12
		COMMAND PID USER   FD      TYPE DEVICE SIZE/OFF  NODE NAME
		systemd   1 root   10u  a_inode   0,13        0 11624 [eventpoll:11,12]
		systemd   1 root   11r      REG    0,4        0 17680 /proc/1/mountinfo
		systemd   1 root   12r  a_inode   0,13        0 11624 inotify
	 systemd monitors fd 11 and fd 12 via eventpoll fd 10.
	[linux]: implement "make check"
	 The target runs check.bash.
