"Bounds Checking Projects... This project has been abandoned" for four years at least.

2008-12-01fix sigset_t size for mips (it's the only arch with 128 signals).Denis Vlasenko
fix _NSIG for it. better document what's going on in sigaction(). seems to not induce any actual code changes (sans mips).

2008-10-19- fix sigaction on older kernels (Michael Deutschmann)Bernhard Reutner-Fischer
In issue #5554 Michael wrote: The implementation of sigaction on i386 for older kernels makes the system call using an inline asm element with two flaws: 1. The asm is not marked as depending on the kact structure or modifying the koact structure. Thus, GCC is free to assume these structures need not be kept consistent, allowing it to remove all initialization of kact. 2. The asm allows the signal number to be provided as a memory reference. But this allows GCC to provide a stack-relative operand, which will break because the assembler saves %ebx on the stack before using that operand. 1 didn't use to be a problem in practice because GCC 4.2.* didn't seize the optimization opportunity. GCC 4.3.2, however, optimizes out the "kact.sa_flags = act->sa_flags | SA_RESTORER;" line, so that the kernel sees garbage in sa_flags. This can result in the kernel seeing the SA_RESETHAND flag, causing erratic behaviour in signal dependent programs. 2 becomes an issue if "-fomit-frame-pointer" is provided. In uClibc-0.9.29 it isn't, uClibc-0.9.30-rc2 does use the flag by default.

2008-06-01Rework smallint machinery so that it will reliably fail to compileDenis Vlasenko
even if arch overrides smallint size. Makes it easier to spot bugs on such arches.

2008-05-19Moving libc_hidden_proto's into #ifdef UCLIBC_INTERNAL blockDenis Vlasenko
in string.h and strings.h. This caught unguarded string ops in libc/inet/ethers.c __ether_line_w() function. I will wait for fallout reports for a week or so, then continue converting more libc_hidden_proto's.

2008-04-24- fixup asm. No object-code changesBernhard Reutner-Fischer
2008-01-17A patch from our Blackfin repository, originally from Jie Zhang. This fixesBernd Schmidt
a problem where the linker was trying to use the wrong symbol name for the init function. Define SYMBOL_PREFIX as _ in Rules.mak for h8300, bfin, i960, microblaze, and v850. Add -D__UCLIBC_UNDERSCORES__ in CFLAGS for targets which define SYMBOL_PREFIX as _. Remove defines and undefs from uClibc_arch_features.h of each target. Add $(SYMBOL_PREFIX) to __uClibc_init when passed by ld option -init.
2008-01-08change NO_UNDERSCORES to just UNDERSCORES so as to be less confusing when ↵Mike Frysinger

2008-01-05michael_d writes in #1874: Mike Frysinger
On an i386 platform with no rt_sigsuspend syscall (ie: Linux 2.0), compilation will halt on libc/sysdeps/linux/common/sigsuspend.os with a cryptic error message: "Error: non-constant expression in ".if" statement" I've investigated and found that the cause is that a literal '0' is being passed into a block of complex assembler macrology that is only prepared to deal with register names - '%eax', etc. In turn, that seems to be because of a typo in the GCC register constraints. The constraints for 2 and 3-argument syscalls includes a "C" constraint. To gcc, "C" means an SSE floating point constant -- an unlikely element in a syscall. I suspect the author meant to type "S" (%esi).
2007-07-29Remove stray code alignment (.align 16 and .align 4 directives)Denis Vlasenko
from i386 and x86_64.
2007-06-24- make sure to define _LIBC in libc-symbols.h before including anythingBernhard Reutner-Fischer
else. - internal_function is only used inside libc, so do not define it in uClibc_arch_features.h on i386 if we are outside of libc.
2007-03-13Using local variable 'result' caused problems with lseek64 syscall failing ↵Khem Raj
with gcc 4.2. Renaming to make it a bit uncommon name.
2007-03-06Add posix_fadvise posix_fadvise64 for arm.Khem Raj
Import INTERNAL_SYSCALL macro for i386 from glibc. Use above macro in posix_fadvise implementation if an arch defines it.
2007-02-28Add a hack for compiling a 32 bit user space with a 64 bit kernel on x86_64Eric Andersen
2006-12-08Take Mike Frysinger's comments into account -- make certain that userEric Andersen
applications stop using _syscall#() and use syscall() instead. Cleanup internal handling of syscall includes to use the correct header file.
