stdio: prevent retries on fclose/fflush after write errors
Some test results:
The longer patch posted at Sun 14:46:24 +0100 made my target system
unbootable. I did not attempt to troubleshoot it, as we are focusing
our efforts on the shorter patch now.
The shorter patch posted at Mon 01:50:27 +0100 is a good start, but it
didn't completely fix the problem for me. I am posting an updated
version with a few changes at the end of this message; the patched
uClibc 0.9.32.1 tree passes both of my test cases.
My changes:
1) Need to break out of the loop on "hard" errors. Otherwise the
library call never returns:
open("/dev/null", O_RDONLY) = 4
dup2(4, 1) = 1
write(1, "hello world\n", 12) = -1 EBADF (Bad file descriptor)
write(1, "hello world\n", 12) = -1 EBADF (Bad file descriptor)
write(1, "hello world\n", 12) = -1 EBADF (Bad file descriptor)
write(1, "hello world\n", 12) = -1 EBADF (Bad file descriptor)
...
2) Move all of the error handling logic back into the "else" clause. In
particular, I believe we do not want to be checking errno unless
__WRITE() had indicated a failure, since the value may be undefined:
if (errno == EINTR
|| errno == EAGAIN
/* do we have other "soft" errors? */
) {
3) Whitespace/indentation consistency.
-- 8< --
From: Denys Vlasenko <vda.linux@googlemail.com>
Currently, uclibc retains buffered data on stdio write errors,
and subsequent fclose and fflush will try to write it out again
(in most cases, in vain).
Which results in something like this:

libc: fix signal handling in system()
When built without NPTL support (or for a sparc target), the system()
function doesn't conform to its specification. Namely, it uses signal()
to install/save/restore signal handlers, which may break applications
using custom handlers installed with sigaction(). In addition, it resets
the SIGCHLD handler to SIG_DFL instead of blocking the signal, which may
result in "lost" signals if a custom handler was installed.
Fix system() by replacing uses of signal() with appropriate calls to
sigaction() and sigprocmask().

libubacktrace: use -asynchronous-funwind-tables rather than -funwind-tables
From gcc documentation, we can read:

used for stack unwinding from asynchronous events (such as debugger or

libc: allow to backtrace out of abort call
Build raise and abort function with dwarf2 info by using
-fasynchronous-unwind-tables to make backtrace() working across a
call to abort.
A scenario where it could be useful is within a signal handler that
wants to dump a backtrace when catching some signal (i.e SIGABRT).
Without having abort & raise built with DWARF2 information, it is not
possible for the libgcc stack unwinder to walk through the call stack
out of the abort/raise function.
