2004-12-22Patch from psm, vapier, and solar, adding xattr syscallsEric Andersen
2004-12-20- Added support for 13 new syscalls to allow more things to compile when ↵Ned Ludd
using uClibc. mincore() and the ones for Extended Attributes setxattr(), lsetxattr(), fsetxattr(), getxattr(), lgetxattr(), fgetxattr(), listxattr(), llistxattr(), flistxattr(), removexattr(), lremovexattr(), fremovexattr() which are optional.

2004-12-08Kill off ancient unused cruftEric Andersen
2004-11-25update : $Ned Ludd
2004-11-11misc cleanups of __stack_smash_handler() function when ssp support is ↵Ned Ludd
enabled. syslog() support should now work both inside and outside of chroots. erandom code left in but remains #ifdef out by default. May remove erandom completely in the future for uClibc unless the LFS guys and gals want to keep it.

2004-11-02struct ipc_perm, as used by shmctl() when soing shared memory stuff,Eric Andersen
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
2004-10-31Revert Peter's __lib_gettimeofday patch. There's the minor issue ofManuel Novoa III
adding cruft to include/sys/time.h. But also, there's no sense in making changes like this until we decide how we're going to approach the hidden symbol transition.

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
2004-08-22Make the stub profiling stuff workEric Andersen
2004-08-21Attempt to support 'gcc -finstrument-functions', which seems muchEric Andersen
more sane than 'gcc -pg' and seems much easier to support. -Erik
2004-08-21Kill off all support for 'gcc -pg' / 'gprof' style profiling. There is both aEric Andersen
size and performance penalty to profiling applications this way, as well as Heisenberg effects, where the act of measuring changes what is measured. There are better tools for doing profiling, such as OProfile, that do not require gcc to instrument the application code. -Erik

2004-08-16The variable used to store pagesize is not the same as theEric Andersen
_dl_pagesize variable in ldso, so avoid aliasing. -Erik

2004-07-30Cleanup some dead wood in the header filesEric Andersen
2004-07-30s/___brk_addr/__curbrk/gEric Andersen
Some utilities, such as valgrind, have a legitimate reason to know the address of the current brk. Since we know such utils will peek under our skirt, we might as well give them what they expect and not use a gratuitously different symbol name. -Erik

2004-05-07Patch from Yoshinori Sato <ysato@users.sourceforge.jp>.Manuel Novoa III
2004-05-07Fix a couple of issues in configurations I hadn't tested.Manuel Novoa III
2004-04-20Cope with gcc 3.4's more aggressive persuit of attribute unusedEric Andersen
2004-04-14Fix typo.Manuel Novoa III
2004-03-19Per patch from Stefan Holst, do not try to compile theseEric Andersen
syscalls if they are not supported.
2004-03-19Based on a patch from Alexandre Oliva, allow uClibc to compileEric Andersen
with __NR_mmap is not available (i.e. only __NR_mmap2)
2004-03-18Based on a patch from Alexandre Oliva, remove all reference to 'bzero' (whichEric Andersen
is not a SuSv3 symbol). Rather than using __bzero internally per Alexandre's original patch, use memset instead.
2004-03-12Cope gracefully with missing module syscallsEric Andersen
2004-02-17Fixup fdatasync on alpha, thanks to Alan HourihaneEric Andersen
2004-02-11New stdio core. Should be more maintainable. Fixes a couple of bugs.Manuel Novoa III
Codepaths streamlined. Improved performance for nonthreaded apps when linked with a thread-enabled libc. Minor iconv bug and some locale/thread related startup issues fixed. These showed up in getting a gcj-compiled java helloworld app running. Removed some old extension functions... _stdio_fdout and _stdio_fsfopen.
2004-02-11Fix bug from the syscall reorganization, detected by python's test_poll.py.Manuel Novoa III
The #ifdef __NR_poll test was failing because it was done before any includes. Hence, the emulation was always being used. NOTE: The emulation fails a couple of tests in test_poll.py!
2004-02-10Do not include the create_module syscall if it is not presentEric Andersen

Here are some simple fixes for things that broke for PPC with the recent syscall cleanup. I am not sure they are correct but they seem pretty trivial.

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
2004-01-02The checking Erik added seems to be unnecessary. Without it, I am notManuel Novoa III

2003-12-31Add extra checks for sigprocmask and rt_sigprocmask syscalls.Eric Andersen
The rt_sigprocmask syscall has broken error handling in 2.4.x kernels, while the sigprocmask syscall appears to get things right. Regardless we should be extra careful, and add these checks.
2003-12-27Fix a long-standing bug with pthreads. A couple of linuxthreads filesManuel Novoa III
were including libc-lock.h which had a bunch of weak pragmas. Also, uClibc supplied a number of no-op weak thread functions even though many weren't needed. This combined result was that sometimes the functional versions of thread functions in pthread would not override the weaks in libc. While fixing this, I also prepended double-underscore to all necessary weak thread funcs in uClibc, and removed all unused weaks. I did a test build, but haven't tested this since these changes are a backport from my working tree. I did test the changes there and no longer need to explicitly add -lpthread in the perl build for perl to pass its thread self tests.
