an offset between ss_sp and struct sa_stackinfo_t (located in struct
__pthread_st) when calling sa_register. The kernel increments the
sast_gen counter in struct sastack when an upcall stack is used.
libpthread increments the sasi_stackgen counter in struct
sa_stackinfo_t when an upcall stack is freed. The kernel compares the
two counters to decide if a stack is free or in use.
- add struct sa_stackinfo_t with sasi_stackgen to count stack use in
userland
- add sast_gen to struct sastack to count stack use in kernel
- add SA_FLAG_STACKINFO to enable the stackinfo_offset argument in the
sa_register syscall
- add sa_stackinfo_offset to struct sadata for offset between ss_sp
and struct sa_stackinfo_t
- add ssize_t stackinfo_offset argument to sa_register, initialize
struct sadata's sa_stackinfo_offset from it if SA_FLAG_STACKINFO is
set
- add sa_getstack, sa_getstack0, sa_stackused and sa_setstackfree
functions to find/use/free upcall stacks and use these where
appropriate
- don't record stack for upcall in sa_upcall0
- pass sau to sa_switchcall instead of l2 (l2 = curlwp in sa_switchcall)
- add sa_vp_blocker to struct sadata to pass recently blocked lwp to
sa_switchcall
- delay finding a stack for blocked upcalls to sa_switchcall
- add sa_stacknext to struct sadata pointing to next most likely free
upcall stack; also g/c sa_stackslist in struct sadata and sast_list
in struct sastack
- add L_SA_WOKEN flag: LWP is on sa_woken queue
- add L_SA_RECYCLE flag: LWP should be recycled in sa_setwoken
- replace l_upcallstack with L_SA_WOKEN/L_SA_RECYCLE/L_SA_BLOCKING
flags
- g/c now unused sast_blocker in struct sastack
- make sa_switchcall, sa_upcall0 and sa_upcall_getstate static in
kern_sa.c
- call sa_upcall_userret only once in userret
- split sa_makeupcalls out of sa_upcall_userret and use to process
the sa_upcalls queue
- on process exit: mark LWPs sleeping in saunblock interruptible; also
there are no LWPs sleeping on l->l_upcallstack anymore; also clear
sa_wokenq_head to prevent unblocked upcalls
additional changes:
- cleanup timerupcall sa_vp == curlwp check
- add check in sa_yield if we didn't block on our way here and we
wouldn't any longer be the LWP on the VP
- invalidate sa_vp_ofaultaddr after resolving pagefault
(for rstartd.real) separate to the LIBDIR (for the configuration)
and install rstartd.real into /usr/X11R6/libexec.
(Installing binaries under /usr/X11R6/lib/X11 (which may be a
symlink to /etc/X11) is Bad.0
Override BINDIR after the .include of <bsd.own.mk>, so that rstartd.real
is installed in the correct location.
brief summary:
* Add NetBSD RCS Ids. Change to use a date based version number.
* Remove unused variables and functions.
* Move towards NetBSD code style.
* Add missing GNU options (except for --include, --exclude and
--line-buffered)
* Bug fixes
* Bug fixes and changes from OpenBSD's src/usr.bin/grep
A full list of changes can be viewed in the NetBSD CVS repository at
othersrc/usr.bin/grep. A ChangeLog is also available at:

- add PTHREAD_PID_DEBUG which prints the pid before each debuglog line
- output thread returned in pthread__next
- add asserts in pthread__sched akin to asserts in pthread__sched_bulk:
check if scheduled thread is at front/end of queue
- pthread__upcall: output event/interrupted LWP count instead of LWPid
of the first event/interrupted LWP (since unblock upcalls can have
multiple event LWPs).
- pthread__find_interrupted: output LWPid here

"Stable CVS 1.11.11 has been released. Stable releases contain only
bug fixes from previous versions of CVS. This release adds code to
the CVS server to prevent it from continuing as root after a user
login, as an extra failsafe against a compromise of the
CVSROOT/passwd file. Previously, any user with the ability to write
the CVSROOT/passwd file could execute arbitrary code as the root
user on systems with CVS pserver access enabled. We recommend this
upgrade for all CVS servers!"
