| | | | | | | | | | Because variables are linked to fixed registers, there is a problem in : (*__errno_location())=(-_r0); As __errno_location() uses r0 to return the address of the errno location, the negated address will be assigned instead of the error code. Attached patch will resolve this.
* It turns out that asm/reg.h is missing from the 2.6.x kernel headers,Eric Andersen2004-04-231-2/+167

| | | | | | | | | | | | | | | | | | | | This patch adds code to uClibc to support a new ABI designed for the FR-V architecture, that enables text segments of executables and shared libraries to be shared by multiple processes on an OS such as uClinux, that can run on FR-V processors without an MMU. Patches for binutils and GCC have just been posted in the corresponding mailing lists. The binutils patch was approved, but there's one additional patch pending review, that I posted this week. An updated GCC patch will be posted to gcc-patches@gcc.gnu.org as soon as I complete testing (I used a known-good compiler to test the uClibc patch below). Since the existing dynamic loader code didn't support independent relocation of segments, it required changes that were somewhat extensive. I've added a number of new machine-specific macros to try to keep the platform and ABI-specific details outside the generic code. I hope this is not a problem.

* New stdio core. Should be more maintainable. Fixes a couple of bugs.Manuel Novoa III2004-02-113-391/+441
| | | | | | | | 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.
* Fix bug from the syscall reorganization, detected by python's test_poll.py.Manuel Novoa III2004-02-111-3/+3
| | | | | | | The #ifdef __NR_poll test was failing because it was done before any includes. Hence, the emulation was always being used. NOTE: The emulation fails a couple of tests in test_poll.py!

* Sigh. The 2.6.x kernel removed '__kernel_dev_t' and renamed it asEric Andersen2004-02-0614-0/+17
| | | | | | | | | '__kernel_old_dev_t'. And of course there is no good way to know which is in use except checking linux/version.h. Grumble. This is rather lame, but for now, define __kernel_old_dev_t to be the same as __kernel_dev_t. This will want to be revisited soon. -Erik

| | | | | | | | | | | | | | | | | | | 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

| | | | | | | The rt_sigprocmask syscall has broken error handling in 2.4.x kernels, while the sigprocmask syscall appears to get things right. Regardless we should be extra careful, and add these checks.

| | | | | | | | | | | | | | | | 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.
