2005-11-15Undo hiding __libc_fcntl[64], CANCELABLE_SYSCALL is not grep friendly ;-(, ↵Peter S. Mazinger
have to find some other way to make it internal to libc and libpthread
2005-11-15Update copyright noticePeter S. Mazinger
2005-11-15Hide __libc_fcntl[64]. Change weak __libc_fcntl* fcntl* to strongPeter S. Mazinger
2005-10-29Hopefully correct undefined __libc_stack_end issuePeter S. Mazinger
2005-10-27Moved guard_setup to dl-osinfo.h (used commonly by ldso and libc). Renamed ↵Peter S. Mazinger
to _dl_setup_stack_chk_guard, as in glibc. SSP requires now binutils-2.16.1 and newer. Add NOT_IN_libc/IS_IN_libc. Began using -DSHARED in uClibc_main.c, there are more candidates in there. Move back dl_protect_relro to it's earlier place.
2005-10-12Remove /dev/erandom support, as [h]lfs does not use it in this form.Peter S. Mazinger
2005-10-08User strong_alias instead of initializing __guard separatelyPeter S. Mazinger
2005-10-03Enable attribute_relro on __guard and __stack_chk_guard now that ld.so ↵Peter S. Mazinger
supports it
2005-10-01Change the order in which '__uClibc_init' is called. In the case of NPTL, ↵"Steven J. Hill"
some auxillary TLS set up has to happen beforehand. This has been tested for almost two months now and I am tired of chasing it around in my merges. Look in the NPTL trunk if you want more information.
2005-10-01Add gcc-4.1 non-TLS __stack_chk_guard support. Run the guard setup only once.Peter S. Mazinger
2005-09-23New ssp code using syscalls where possible.Peter S. Mazinger
Moved guard_setup to __uClibc_main.c, the only place where it is called. Removed SIGKILL option, not usable with sigaction.
2005-09-21correct some typosPeter S. Mazinger
2005-09-08punt _DL_FINI_CRT_COMPAT option now that 0.9.28 has been releasedMike Frysinger
2005-09-08Fix by Martin Schlemmer:Mike Frysinger
If _DL_FINI_CRT_COMPAT is defined, _dl_fini is setup to run at exit via atexit(), but this makes it run _before_ the fini (__app_fini()) of the app, causing stuff like sandbox that frees structs, etc via its fini to segfault. http://bugs.gentoo.org/98187

2005-06-29Add __libc_stack_end to libc.Joakim Tjernlund
2005-05-28Add Peter Mazinger fini/crt compat patch. Select DL_FINI_CRT_COMPAT toJoakim Tjernlund
be able to run apps built with 0.9.27. This also renames __uClibc_start_main to __uClibc_main. This compat option should be removed some time after 0.9.28 is released. Let me know if you don't like this change.
2005-05-26This commit breaks the entire world (yet again). Calculate theEric Andersen
position of envp in C code based on argv and argp. No need to caclulate that in asm for N arches. This way, we better match what glibc does. All arches will need to be fixed to match up with this change.
2005-05-25Adapt startup code in x86 and PPC to almost match glibc. _init vs. ↵Joakim Tjernlund
__libc_csu_init and _fini vs. __libc_csu_fini remains to do.
2005-05-21Pass main function ptr from crt1 to __uClibc_start_main.Joakim Tjernlund
Kill old crt0/__uClibc_main. This breaks ABI. All apps and toolchain needs to be recompiled. All archs except x86 are now broken and need to be fixed as x86. PPC will be fixed shortly by me, the rest is left to the arch maintainers.
2005-03-20Prepare for moving ldso FINI handling into libc.Joakim Tjernlund
#define _DL_DO_FINI_IN_LIBC to enable(the arch specific part needs to be in place first).

2004-08-16Setup __pagesize from inside __uClibc_init(), or else when registeringEric Andersen
dtors via atexit(), atexit may need to call realloc with __pagesize still set to 0. ugh. -Erik
2004-08-16Be a bit more prominant about the fact that setuid handlingEric Andersen
is not quite there...
2004-08-16The variable used to store pagesize is not the same as theEric Andersen
_dl_pagesize variable in ldso, so avoid aliasing. -Erik

2004-08-04Add missing header file needed to define PAGE_SIZEEric Andersen
2004-08-03As Joakim Tjernlund rightly notes, I should have used PAGE_SIZEEric Andersen
not the hard coded value of 4096.
2004-07-28Do not grovel about in the ELF header for the page size whenEric Andersen
running on uClinux, which at runtime uses the FLAT file format.

2004-01-02Peter S. Mazinger writes:Eric Andersen
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
2003-12-27Handle the app_fini stuff in exit without requiring atexit().Manuel Novoa III
This avoids pulling in all the malloc/free code for a simple true/false app.
2003-06-30Yield to yet another glibc-ism and add __prognameEric Andersen
2003-01-23Making atexit weak does nothing for dynamicly linked apps. And forEric Andersen
staticly linked apps it entirely prevents destructors from running unless atexit is called for some other reason. So if they enabled ctor/dtor support we need to have a call to the real atexit for dtors to work properly. If people don't want the extra 4k or so of junk in their static apps, they should leave ctor/dtor support disabled. -Erik
2002-10-01This commit contains a patch from Stefan Allius <allius@atecom.com> to changeEric Andersen
how uClibc handles _init and _fini, allowing shared lib constructors and destructors to initialize things in the correct sequence. Stefan ported the SH architecture. I then ported x86, arm, and mips. x86 and arm are working fine, but I don't think I quite got things correct for mips.

2002-05-06New locale support (in development). Supports LC_CTYPE, LC_NUMERIC,Manuel Novoa III
LC_TIME, LC_MONETARY, and LC_MESSAGES for the SUSv3 items. Also, nl_langinfo() when real locale support is enabled. New implementation of ctype.h. New implementation of wctype.h. New implementation of most of the string functions (smaller). New implementation of the wcs/wmem functions. These are untested, but they're also just preprocessor-modified versions ot the corresponding str/mem functions. Tweaked qsort and new bsearch. Stuff still pending: stdlib.h and wchar.h mb<->wc functions. I actually have working versions of the stdlib ones, but the reentrant versions from wchar.h require some reworking. Basic replacement and translit support for wc->mb conversions. (groundwork laid). Simple-minded collate support such as was provided by the previous locale implementation. (mostly done -- 8-bit codesets only) Shared mmaping of the locale data and strerror message text.
2002-04-17Patch from Martin Proulx to remove weak_aliases for non ELF compilers inEric Andersen
__uClibc_main for the _stdio_init and _stdio_term functions. Since weak_aliases are defined as hard aliases for non ELF compilers, these 2 symbols ended up to be multiply defined, as those two are defined in stdio.c.
2002-04-01Patches from Yoshinori Sato <qzb04471@nifty.ne.jp> to fix h8300Eric Andersen
support for pthreads and update for the latest and greatest.
2002-03-15Fix non-elf support (in theory). Revert misguided change suggestedEric Andersen
by arcturusnetworks, since Miles Bader reports it is unnecessary. -Erik
