cooperating with the callout code in working around the race
condition caused by the TCP code's use of the callout facility.
Instead of unconditionally releasing memory in tcp_close() and
SYN_CACHE_PUT(), check whether any of the related callout handlers
are about to be invoked (but have not yet done callout_ack()), and
if so, just mark the associated data structure (tcpcb or syn cache
entry) as "dead", and test for this (and release storage) in the
callout handler functions.
to make users of the callout facility able to cooperate to work around the
race caused by the callout code lowering interrupt priority level when
invoking callout handlers, something which allows other code to run before
the callout handler gets to it's spl*() call.
This is to enable the workaround for the TCP code found in PR#20390 to be
applied.
This should be backed out once a more comprehensive fix can be put in
place.
a non-zero exit value to indicate a missing file or non-symlink),

instead instead of unconditionally installing the link.
SYMLINKS: use stat -qf '%Y' $l to read a symlink's target (and rely upon
a non-zero exit value to indicate a missing file or non-symlink),
instead of test -h $l && ls -ld $l | awk '{print $NF}' , since
the former is quicker and more concise.

Don't ignore grotty's command line options if \X'tty: sgr ...' is
used to change the drawing scheme.
* src/devives/grotty/tty.cpp (bold_flag_option,
underline_flag_option, italic_flag_option, reverse_flag_option,
bold_underline_mode_option): New global variables.
(update_options): New function.
(tty_printer::special): Call update_options.
(main): Don't set xxx_flag but xxx_flag_option, then call
update_options.
According to lex(1) (the manual page for flex, which is what we use for lex):
Finally, note that you cannot put back EOF to attempt to mark the
input stream with an end-of-file.
Fixes PR bin/8707, which had been reclassified as a toolchain bug.
and sent in by Greg Hudson as seen in PR misc/3227. Basically what it
does is adds a flushall option which deletes all but localhost routes.
This is done by andoring in a flag called doall (1 means do all routes
including gateway, 0 means do a regular flush). I have seen some
platforms that do this. I tested it out on ipv4 only, it works as
advertised. Commit was approved by christos@.
pthread_attr_t objects, although most of the properties being set don't really
affect threads yet:
pthread_attr_{get,set}guardsize()
pthread_attr_{get,set}inheritsched()
pthread_attr_{get,set}scope()
pthread_attr_{get,set}stack()
pthread_attr_setstack{size,addr}()
Remove some useless assertions and error checks in the existing pthread_attr()
routines.
Implement pthread_attr_get_np(), to examine the attributes of an existing
thread. Idea and interface from FreeBSD.
Change PTHREAD_ERRORMODE environment variable to PTHREAD_DIAGASSERT, and
make it behave like libc's LIBC_DIAGASSERT. The way to disable error-checking
and aborting is now "PTHREAD_DIAGASSERT=AEL", rather than
"PTHREAD_ERRORMODE=ignore".
including (interface borrowed from FreeBSD) pthread_attr_get_np().
Remove a few limit-indicating symbols that don't actually need to be defined
(and if they did need to be defined, it would be in limits.h, not here).
