2008-12-01 | fix 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). | |||
2008-11-20 | next portion of libc_hidden_proto removal | Denis Vlasenko | |
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. | |||
2008-07-23 | - trim any trailing whitespace | Bernhard Reutner-Fischer | |
2008-05-19 | Moving libc_hidden_proto's into #ifdef UCLIBC_INTERNAL block | Denis 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. | |||
2007-07-29 | Remove stray code alignment (.align 16 and .align 4 directives) | Denis Vlasenko | |
from i386 and x86_64. | |||
2006-02-02 | even the hidden version of the weaks in libc (as strong in libpthread) have ↵ | Peter S. Mazinger | |
to be weaks | |||
2006-01-26 | Get rid of missing prototype warnings | Peter S. Mazinger | |
2006-01-25 | Guard the use of sigreturn as in x86_64, thx blindvt | Peter S. Mazinger | |
2006-01-23 | make sigaction/raise/sigwait/siglongjmp/longjmp weak_alias, these are in ↵ | Peter S. Mazinger | |
libpthread as well | |||
2006-01-23 | Make i386 build w/ -std=c99 (almost) | Peter S. Mazinger | |
2006-01-15 | make gcc4 happy w/ hidden_def/proto, correct some typos | Peter S. Mazinger | |
2006-01-14 | hidden_def/hidden_proto: convert all users (I hope) termios split, add some ↵ | Peter S. Mazinger | |
missing headers, other jump relocs removed | |||
2005-12-10 | Merge from NPTL branch. Bring in the remaining changes for sigaction. | "Steven J. Hill" | |
2005-12-08 | Try to mimic glibc sigaction, sjhill, could you please test w/ this version? | Peter S. Mazinger | |
2005-12-03 | More hiding, including __mempcpy | Peter S. Mazinger | |
2005-12-01 | Hide mostly used functions | Peter S. Mazinger | |
2005-11-21 | tweak restore function definitions like glibc does it to get rid of warnings | Mike Frysinger | |
2003-02-03 | Oops. I'd left an extra invocation of sigaction in there... | Eric Andersen | |
2003-01-22 | Update sigaction syscall names to act more like glibc. Fix the x86 sigaction | Eric Andersen | |
implementation such that gdb can actually debug signal handlers. Gdb behaves much better now, for example, on multi-threaded apps. -Erik |
