2014-08-20fix for pipe() on sparcWaldemar Brodkorb
When using something like this: $ echo foo|grep foo|wc -l with mksh shell, you get an runtime error. Glibc and klibc does not do these extra check. After removing this check using double pipes work fine. Tested with Qemu 2.1.0.

2014-08-18libc: add issetugid()Anthony G. Basile
issetugid() returns 1 if the process environment or memory address space is considered tainted, and returns 0 otherwise. This happens, for example, when a process's privileges are elevated by the setuid or setgid flags on an executable belonging to root. This function first appeard in OpenBSD 2.0 and is needed for the LibreSSL. This patch follows the same logic as the equivalent musl commit.

2014-08-18lseek: Correct order of offset argumentsAnton Kolesov
There was a runtime error in systems without large file support. Call fseek(fd, 4096, SEEK_SET) has been failing with EINVAL, though it was succeeding for offset = 4092. This has been happening because llseek system call accepts 64-bit value as an offset argument and lseek function has been ordering 32-bits words that form this offset value, according to the endianness. However this ordering to match endianness is not required, because llseek doesn't accept one 64-bit offset argument, it accepts two 32-bit offset argument, then stitches them into one following its endianness. As a result on little endian system, order of words has been swapped two time: in libc and in kernel. Thus call to fseek with offset 4096 (0x1000) was doing a system call to llseek with offset 0x1000_0000_0000. I'm not entirely sure why then offset = 4092 hasn't been failing then. This patch removes malicious swap of words when calling llseek. Signed-off-by: Anton Kolesov <Anton.Kolesov@synopsys.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2014-08-18libc: posix_fadvise: Fix build breakage for !LFSVineet Gupta
commit 00571b43df2e "libc: posix_fadvise: restore implementation for xtensa" enabled posix_fadvise() for all arches (it was just not generated before). However this also unearthed an issue introduced by ee84b8b400 "linux: posix_fadvise: use new SYSCALL_ALIGN_64BIT" which is to referencing LFS'ish code (off64_t) w/o proper checks which causes build to break for !LFS. Fix this by calling posix_fadvise64() only for LFS case and open-code it's equivalent for !LFS.

2014-08-18ARC/NPTL: clone to set TP if CLONE_SETTLSVineet Gupta
Typically kernel would set the TP register of newly created thread in clone syscall with CLONE_SETTLS. However this implies that: * kernel knows of the exact TP register (which is already different for ARCompact and ARCv2) and is a detail which becomes part of the ABI * kernel also needs to handle the unlikely but possible case of !TLS userspace (e.g. Android libc) case where TP reg is not reserved and thus need not be mucked with (using ELF personality based detection) It is better to confine this detail to userspace runtime and set TP reg right after clone syscall returns.

2014-04-23weak symbols need to be "defined" weak but "declared" strongVineet Gupta
Patch "LT.old: Make __errno_location/__h_errno_location thread safe" uncovered yet another bug with static linking and errno (hopefully this is last of them all). Currently, __errno_location is declared weak but is defined strong. While this provides with the desired weak semantics in dso, it is subtly broken in static links. Quoting Joern Rennecke (ARC gcc expert): | I think the issue is that you declare the function as weak in the | header file. That is a rare instance where you want the reference | use declaration that differs a bit from the definition. | If the reference uses a weakly declared function, that creates a | weakref, i.e. the linker won't bother to look for this symbol at | all - if it gets linked in for some other reason, fine, | otherwise, it stays zero. So the solution to declare strong, define weak. Supporting data ----------------- orig code: ARM mmap wrapper (LT.old build + my prev patch for errno) _mmap: @ args = 8, pretend = 0, frame = 0 @ frame_needed = 0, uses_anonymous_args = 0 stmfd sp!, {r4, r5, r7, lr} ldr r5, [sp, #20] movs ip, r5, asl #20 beq .L2 bl __errno_location(PLT) mov r3, #22 str r3, [r0, #0] mvn r0, #0 ... ... .weak __errno_location A statically linked hello world program which uses mmap too. As we can see__errno_location is completely gone - which is semantically wrong - we need functional errno. 00008274 <__GI_mmap>: 8274: e92d40b0 push {r4, r5, r7, lr} 8278: e59d5014 ldr r5, [sp, #20] 827c: e1b0ca05 lsls ip, r5, #20 8280: 0a000004 beq 8298 8284: e320f000 nop {0} ^^^^^^^^^^ 8288: e3a03016 mov r3, #22 828c: e5803000 str r3, [r0] 8290: e3e00000 mvn r0, #0 This in turn is due to a fixup in ARM ld which transforms branch-to-null into a nop. It is better than crashing but still wrong since errno handling is removed.

2014-04-23LT.old: Make __errno_location/__h_errno_location thread safeVineet Gupta
WHY: errno in uClibc is not thread safe HOW: __errno_location and it's sibling __h_errno_location need to be called via PLT - even from within libc. That way when linked with pthread, intra-uClibc callers will also use the thread safe version. This is achieved by removing the GI alias for these functions, ensuring that they get called normally (via PLT) Verified with ARC LT.old and ARM cubieboard2 buildroot (LT.old) NPTL is unaffected by this bug. ------------ History behind this patch --------------------- This is a long standing bug (https://bugs.busybox.net/show_bug.cgi?id=2089) Others have tried to fix it in past (alteast Peter Korsgaard's patch in 2010), but somehow failed to be merged (or were backed out afterwards). http://lists.uclibc.org/pipermail/uclibc/2010-July/044176.html One of the causes could be side effect of atleast one more bug related to pthreads and static link which has now been fixed. http://lists.uclibc.org/pipermail/uclibc/2013-October/047958.html I have solved this w/o looking at other pacthes but would like to give credit to Peter and others for confirming that it makes sense.

2014-02-15mips: Remove duplicate macro definitionsSteve Ellcey
The INLINE_SYSCALL, INTERNAL_SYSCALL*, and internal_syscall* macros are defined for MIPS in both libc/sysdeps/linux/mips/sysdep.h and libc/sysdeps/linux/mips/bits/syscalls.h. The macros are the same in both cases except that syscalls.h defines internal_syscalls[567] the same for N32 and N64 ABIs and has a different definition for O32. I believe that is correct. The sysdep.h header uses the O32 versions for N32 and has different definitions for N64. I think that is wrong and that N32 and N64 should share the same definition (modulo the type 'long' vs. 'long long' for the arguments. This setup (from sysdep.h) now agrees with what glibc has. I am not positive about which header (sysdep.h vs syscalls.h) is really the right one to have these definitions in but using sysdep.h seems to work for all my builds.

2014-01-22libc: fix MIPS N64 forkWaldemar Brodkorb
fork() is broken for MIPS64 N64 ABI. You can check it with a simple C program statically linked with qemu-mips64 user emulation. Internally fork() is using the clone system call (at least with NPTL) with 5 arguments. See ./libpthread/nptl/sysdeps/unix/sysv/linux/i386/fork.c. The calling conventions for MIPS N32 and N64 allow to use up to 8 registers for that. See http://en.wikipedia.org/wiki/Calling_convention#MIPS This is correctly implemented in libc/sysdeps/linux/mips/bits/syscalls.h, but not in libc/sysdeps/linux/mips/sysdep.h. fork.c uses the later one. It seems that fork() works fine for MIPS64 N32 with just using the stack like with the O32 case. There is a user of INLINE_SYSCALL with 7 arguments in libc/sysdeps/linux/common/sync_file_range.c for MIPS64 N32, so I decided to only use the macros for the MIPS64 N64 case. With this patch my uClibc based Linux system boots up fine in qemu-system-mips64. Signed-off-by: Waldemar Brodkorb <wbx@openadk.org> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2013-11-12Make res_init() thread safe.Kenneth Soerensen
res_init() was not atomic, which could give undesired behaviour. Now res_init() is completely locked under one lock and the locking is removed from __res_vinit(). Signed-off-by: Kenneth Soerensen <kenneth.sorensen@spectralink.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2013-11-12Fix threaded use of res_ functions.Sørensen, Kenneth
Commit aab4df0fb51660300559f5f29290709db2f7bfee says that the line with after res_init() function. Commit 7f74de5d4d6d10baafab4b37bb3d472f5c5f0e8c moves the res_init() function below the line with #undef _res. This commit moves res_init() back above #undef _res.

2013-11-06prctl: fix system call wrapperBaruch Siach
The argument names used in the prctl wrapper collide with the internal variable names in syscall wrapper macros on some architecture. This currently breaks xtensa. grep for '\b_a[0-9]' indicates that metag and microblaze might also be affected. Prefix argument names with '_prctl' to avoid collision.
