2011-03-03remove ucontext.h and guard sigstack structure with SUSV4_LEGACY and ↵Peter S. Mazinger
STRICT_HEADERS Remove ucontext.h if SUSV4_LEGACY is not set and fix it's references. Guard sigstack structure with SUSV4_LEGACY and STRICT_HEADERS. Disable sigstack function prototype, it is not provided by uClibc. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net>
2011-03-03remove error handling from some syscallsPeter S. Mazinger
Remove error handling from getegid/getgid/geteuid/getuid/getppid/getpid/getpgrp Use strong_alias if fallbacks are needed Signed-off-by: Peter S. Mazinger <ps.m@gmx.net>
2011-03-03fix stubsPeter S. Mazinger
We use enosys_stub only in this file so make it static Signed-off-by: Peter S. Mazinger <ps.m@gmx.net>
2011-03-03Correct ssp codePeter S. Mazinger
Avoid using strong_alias in ssp, some archs dislike it. Make stack_chk_guard static. Export __stack_smash_handler only if compatibility option is enabled. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net>

2011-03-03use common sigthread.hPeter S. Mazinger
NPTL build did not use the correct bits/sigthread.h, use a common version avoiding this. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net>
2011-02-25nptl:arm: add a wrapper for .cfi_sections pseudo-opsCarmelo Amoroso
ARM disables by default the support for ASM CFI directives. Anyway using an old version of binutils that does not support some new pseudo-op, the build fails as below: AS libpthread/nptl/sysdeps/unix/sysv/linux/close.oS libpthread/nptl/sysdeps/unix/sysv/linux/close.S: Assembler messages: libpthread/nptl/sysdeps/unix/sysv/linux/close.S:9: Error: unknown pseudo-op: `.cfi_sections' The problem is that the .cfi_sections pseudo should be wrapped by a macro that expands to nothing when the CFI is off.

2011-02-22bfin: fix fp reference in _JMPBUF_UNWINDSMike Frysinger
We want to access the frame pointer, so do so directly rather than "overflowing" the pregs array and ending up at the fp member. This fixes the Blackfin build warnings: libpthread/linuxthreads.old/ptlongjmp.c: In function 'pthread_cleanup_upto': libpthread/linuxthreads.old/ptlongjmp.c:35: warning: array subscript is above array bounds libpthread/linuxthreads.old/ptlongjmp.c:56: warning: array subscript is above array bounds Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2011-02-21bfin: add support for new cacheflush syscallSteve Kilbane
Newer gcc's will generate a call to cacheflush when updating jump tables, and that has to be done in kernel space (to avoid hardware anomalies). So make sure uClibc provides that symbol. Signed-off-by: Steve Kilbane <steve@whitecrow.demon.co.uk> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2011-02-21bfin: fix sram/dma syscall definitionsSteve Kilbane
Once we pull in the header, we're forced to declare the syscall with all the right types. Signed-off-by: Steve Kilbane <steve@whitecrow.demon.co.uk> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2011-02-11Fix GNU make v3.80 compatibilityKevin Cernekee
Commits 1f6601a and 094d82d introduced the "else ifeq" construct, which requires GNU make v3.81 or higher. This breaks the build on RHEL4 hosts. Signed-off-by: Kevin Cernekee <cernekee@gmail.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2010-11-10microblaze: syscall interfaceSteven J. Magnani
Fix the microblaze syscall interface. Recent mainline kernels no longer carry userland code to invoke syscalls and microblaze can use the uClibc generic code. Signed-off-by: Steven J. Magnani <steve@digidescorp.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2010-11-10microblaze: Fix crt bootstrapSteven J. Magnani
Rework crt bootstrap to work with the new __uClibc_main(), and hardwire crt init/fini code since the awk approach to generating it on the fly doesn't work for microblaze. The output from the gcc 4.1.2 compiler is scrambled so that the tags expected by the awk script to bracket the init/fini entry and exit code no longer do. Signed-off-by: Steven J.

2010-10-27Fix msync() redefinition for noMMU buildBernhard Reutner-Fischer
An architecture that _may_ have a MMU (and thus implements the msync syscall), but for which the kernel and uClibc are built as noMMU, we have a stub for msync. Thanks to Steven J. Magnani for noticing. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2010-10-27mips: fix errno setting after syscallAlexander Gordeev
If there was an error during syscall then after it's completion a3 register holds a non-zero value and v0 holds an actual error code which should be saved in errno. This can be achieved by calling __syscall_error with the value from v0 as a parameter. So this value should be stored in a0, but the appropriate assembly instructions are missing. Fixed this now by adding "move a0, v0". I think it was once fixed by 58c5f8ba4cdf62342d05a546d15404cbbb3c4e07 but then something went wrong. Again...
