This code in uClibc would attempt to set the default facility if
none was specified. Except none being specified is 0, which is
also LOG_KERN, therefore klogd could never get kernel messages
logged as LOG_KERN.

instead. Based on an initial patch from Tobias Anderberg, but reworked. I
asked Tobias to look into doing something more like what is done in busybox,
but that proved to be a pain.
One possible concern is that these buffers will probably show up as
memory leaks i.e. with valgrind. Perhaps we should add in an atexit
call to free this memory right after we allocate it?

were returning). Anyway, also make them threadsafe and smaller. The
error.c file still needs work.

Codepaths streamlined. Improved performance for nonthreaded apps
when linked with a thread-enabled libc.
Minor iconv bug and some locale/thread related startup issues fixed.
These showed up in getting a gcj-compiled java helloworld app running.
Removed some old extension functions... _stdio_fdout and _stdio_fsfopen.

missing one in the glibc abi, and including a number of extras (which I
left in commented).
Unfortunately, this brings back the perl pthread bug. Fixing the incorrect
weaks in libpthread wasn't sufficient to escape the shared loader bug. :-(

Hello Erik!
I have made some cosmetical changes to the files, removed the added
SCRT=-fPIC option from building the crt0.S file (but it is a requirement
to build them with -fPIC), and changed some comments. I have left the
ldso.c patch with PIE_SUPPORT ifdefs, but consider applying it w/o them
(see some earlier comment from PaX Team on this issue, as it is considered
a bug). To have it work correctly, you'll also need removing
COMPLETELY_PIC.
One thing is missing: PIE_SUPPORT should be usable only for i386 (for
now).
Also added the support for propolice protection (that works for me and
catches memcpy/strcpy attacks (but needs a special gcc version).
Thanks, Peter

This avoids pulling in all the malloc/free code for a simple true/false app.

were including libc-lock.h which had a bunch of weak pragmas. Also,
uClibc supplied a number of no-op weak thread functions even though
many weren't needed. This combined result was that sometimes the
functional versions of thread functions in pthread would not override
the weaks in libc.
While fixing this, I also prepended double-underscore to all necessary
weak thread funcs in uClibc, and removed all unused weaks.
I did a test build, but haven't tested this since these changes are
a backport from my working tree. I did test the changes there and
no longer need to explicitly add -lpthread in the perl build for
perl to pass its thread self tests.

Normalize the tm_isdst value to -1, 0, or 1.
If no dst for this timezone, then reset tm_isdst to 0.

Also fix a dst-related bug which caused the use of uninitialized data.

Remove the ADD_LIBGCC_FUNCTIONS option and do things the right way.
Either we have a shared libgcc available, or the libgcc routines
aren't PIC and don't belong in the shared libc anyway.

ln.patch:
* Define $(LN) as ln in Rules.mak.
* Change all occurrences of ln into $(LN).
* Change all constructs like (cd path && ln -sf foo/file file)
into $(LN) -sf foo/file path/file. The latter construct is
already used in a number of places so it should not be
an additional compatibility problem.
|
|
rm.patch:
* Define $(RM) as rm -f in Rules.mak and test/Rules.mak
(this is the same definition as gmake uses by default).
* Change all occurrences of rm and rm -f into $(RM).

Here's a patch... Since they aren't SUSv3 functions, I don't know if
they'll ever get officially added, but it helps with BSD porting and
allows quite a few Gentoo ebuilds to compile without changing anything.

Also, disable the locale link_warnings for now, as they generate a
lot of noise when using libstd++.

Hack a fix for ctype support of 8-bit codeset locales.
Note: toupper/tolower mappings do not handle the special cases for the
tr_TR and az_AZ locales, since the wide versions currently handle them
either. That will be addressed when I rewrite the data generation tools
and the libc locale code.
|
|
I hate to add this stuff, but it is specified by SuSv3...
|
|
Move stub gettext functions to a stub libintl to make switching in
gnu gettext easier. Also add a few gnu-isms.
Change to using hidden names with global weak aliases for the extended
locale functions, as expected by libstd++.
Slightly rework the locale data generation stuff to allow pregenerated
locale data to be used with buildroot.

Should be standards compliant and with several optional features,
including support for hexadecimal float notation, locale awareness,
glibc-like locale-specific digit grouping with the `'' flag, and
positional arg support. I tested it pretty well (finding several
bugs in glibc's scanf in the process), but it is brand new so be
aware.
The *wprintf functions now support floating point output. Also, a
couple of bugs were squashed. Finally, %a/%A conversions are
now implemented.
Implement the glibc xlocale interface for thread-specific locale
support. Also add the various *_l(args, locale_t loc_arg) funcs.
NOTE!!! setlocale() is NOT threadsafe! NOTE!!!
The strto{floating point} conversion functions are now locale aware.
The also now support hexadecimal floating point notation.
Add the wcsto{floating point} conversion functions.
Fix a bug in mktime() related to dst. Note that unlike glibc's mktime,
uClibc's version always normalizes the struct tm before attempting
to determine the correct dst setting if tm_isdst == -1 on entry.
Add a stub version of the libintl functions. (untested)
Fixed a known memory leak in setlocale() related to the collation data.
Add lots of new config options (which Erik agreed to sort out :-),
including finally exposing some of the stripped down stdio configs.
Be careful with those though, as they haven't been tested in a
long time.
(temporary) GOTCHAs...
The ctype functions are currently incorrect for 8-bit locales. They
will be fixed shortly.
The ctype functions are now table-based, resulting in larger staticly
linked binaries. I'll be adding an option to use the old approach
in the stub locale configuration.

Add a few misc functions mentioned in time.h.
Revert davidm's change regarding using a define for the "/etc/TZ" path,
as this is eventually meant to be a configurable extension and not
unconditionally supported.

glob(...,pglob) used the GLOB_DOOFFS flag to reserve the first
pglob->gl_offs slots of pglob->gl_pathv, globfree(pglob) would attempt
to free the objects pointed to by those slots. If those objects were not
on the heap, the system would crash.
The attached patch fixes this.

It turns out that uClibc's syslog.c does not close sockets when
doing retries and when it exits due to errors. This patch fixes
it.
