* struct ipc_perm, as used by shmctl() when soing shared memory stuff,Eric Andersen2004-11-021-1/+1
| | | | | | | | | was incorrect in uClibc, and was 2 bytes too short. This caused uClibc shared memory stuff to not behave correctly since struct ipc_perm was included as the first member of, i.e. struct msqid_ds, so the content of that struct were all shifted by two bytes. ugh. Apparently, few people have used shared memory, msgctl(), etc with uClibc thus far, -Erik

Hmm... I found a old fix in uClibc ML archive. http://www.uclibc.org/lists/uclibc/2002-September/004459.html But it seems somewhat broken. How about this fix instead? I tested mmap with syscall() in mips. mips64 is not tested.

| | | | | | | | | | | Hello! Would the attached patch be acceptable (maybe instead of __libc_gettimeofday using __gettimeofday) We have some issues, see http://bugs.gentoo.org/show_bug.cgi?id=65892

| | | | | | | | | In a recent post to linux-mips ML (and libc-alpha ML), a problem with inline syscalls was reported. http://www.linux-mips.org/archives/linux-mips/2004-10/msg00142.html It seems uClibc should be fixed also for newer gcc. Here is a patch.

| | | | | | | | | | | | | | | The attached patch generalizes the use of PIE (all archs are brought in sync that use/mention it: x86/ppc/frv) and makes use of it building the target utils. Tested on x86, ppc should be tested, frv uses -fPIE at one location, but at another place -fpie, I don't know which is correct (could be both) and misses the target addition in Config.in. The test for ppc (requires the earlier sent crt-correction patch to work correctly): enable UCLIBC_PIE_SUPPORT, build uClibc and utils, check: file ./utils/ldd, it should show shared object (instead of executable)

| | | | | | | | | | | | | | | | | | | | | | | Hi. I found a mismatch between uClibc and kernel in semctl definition. In uClibc/libc/misc/sysvipc/sem.c: static inline _syscall4(int, __semctl, int, semid, int, semnum, int, cmd, union semun *, arg); ... int semctl(int semid, int semnum, int cmd, ...) ... arg = va_arg (ap, union semun); ... return __semctl(semid, semnum, cmd, &arg); But kernel's semctl is: asmlinkage long sys_semctl (int semid, int semnum, int cmd, union semun arg) The last argument is an union semun itself, not a pointer to the union. Here is a patch.

* Add a couple of mips-specific string funcs.Manuel Novoa III2004-09-0234-2/+3706
| | | | | | | | | Port the generic optimized string funcs from glibc, with some tweaks to cut their size a little. The main change is making memmove call memcpy for forward copying to trim redundant code. Make use of both the generic and arch-specific speed-optimized string funcs configurable. Arch-specific take precedence over generic, and generic takes precedence over basic size-optimized uClibc funcs.

| | | | | | | | | | | | i sent this earlier but perhaps people missed it the first time around :) http://www.uclibc.org/lists/uclibc/2004-August/009544.html basically if you try to #include <sys/ucontext.h> on arm it'll fail because ucontext.h utilizes typedefs found in bits/sigcontext.h ... i386 already has this fix in uClibc find attached a trivial patch to fix this -mike
* Patch by Carl SHAW <carl.shaw@st.com>...Manuel Novoa III2004-08-252-1/+107
| | | | | | | | | | | | Below is a patch to make the pread and pwrite calls work on the SH architecture. I've only tested this on the SH4 with a 2.4.24 kernel - a fairly recent kernel is required as the problem is partially fixed in the kernel itself. For more information (in relation to glibc, but the problem is the same) see the thread at http://sourceforge.net/mailarchive/message.php?msg_id=2375908 Someone should really test this on the SH2/3...
