>Description:

	The advent of netbsd-10 broke sysutils/tsm8, a linux binary
	that we have been running on NetBSD since NetBSD 2.

	A backup run will send a few dozen files, then stall until
	interrupted.

	After the last successfully submitted file, the ktrace has a
	lot of recvfrom and sendto calls, each followed by

  3873   3873 dsmc     RET   gettimeofday 0
  3873   3873 dsmc     CALL  futex(0x13fab14,FUTEX_WAIT_BITSET_PRIVATEFUTEX_CLOCK_REALTIME,0x183,0x7f7fffff24f0,0x13fc4c0,0xffffffff)
  3873  11319 dsmc     RET   futex -1 errno -110 Operation timed out
  3873  11319 dsmc     CALL  futex(0x142ed30,FUTEX_WAKE_PRIVATE,1,0x7f7ff2212bd0,0,0x142ed30)
  3873  11319 dsmc     RET   futex 0
  3873  11319 dsmc     CALL  futex(0x7f7fdc03d93c,FUTEX_WAKE_OP_PRIVATE,1,1,0x7f7fdc03d938,0x4000001)
  3873  23543 dsmc     RET   futex 0
  3873  23543 dsmc     CALL  futex(0x7f7fdc0413e0,FUTEX_WAIT_PRIVATE,2,0,0x7f7fdc0413e0,0xb4)
  3873  11319 dsmc     RET   futex 1
  3873  11319 dsmc     CALL  futex(0x7f7fdc0413e0,FUTEX_WAKE_PRIVATE,1,1,0,0x7f7fdc0413e0)
  3873  23543 dsmc     RET   futex 0
  3873  23543 dsmc     CALL  gettimeofday(0x1117310,0)
  3873  23543 dsmc     RET   gettimeofday 0

	(I can provide the entire humongous ktrace file on request)
	and I understand netbsd-10 brought changes to the linux compat
	system call.

	The tsm package works fine in emulation under netbsd-9 and
	(ftfoi) freebsd13.

	I am setting priority "high" since this bug stops a handful of
	servers here from an upgrade to netbsd-10.


>How-To-Repeat:

	Install sysutils/tsm8, attempt to backup a filesystem. The
	backup run will stall eventually.


>Fix:

	Yes, please.

 	pkgsrc/sysutils/tsm8: DESCR Makefile PLIST distinfo options.mk

 Log Message:
 sysutils/tsm8: Update to v8.1.27.0

 This is a patch release, upstream does not provide a changelog

 Product rename, update HOMEPAGE and DESCR

 Clean up NOT_FOR_PLATFORM, there is no supported suse_emul for NetBSD 1.5

 Point dsmj script to the selected JDK. Java support is currently
 broken; upstream went from a conservative jdk 8 straight to mandating
 their "semeru" fork of OpenJDK, which does not run on NetBSD

 XXX tsm still does not work on netbsd-10+, see PR kern/58677

 A ktrace.out from a dsmc backup run (amd64 netbsd-10 userland, 10.99.15=20
 kernel) is at

 Cheerio,
