2014-11-10statfs: fix compile error when UCLIBC_LINUX_SPECIFIC is not setAnthony G. Basile
statfs() is a Linux-specific function. When building without UCLIBC_LINUX_SPECIFIC set, libc_hidden_proto(statfs) in include/sys/statfs.h is unmatched with libc_hidden_def(statfs) in libc/sysdeps/linux/common/statfs.c, leading to a compile error. This patch fixes this, as well as adds statfs() to the list of Linux-specific functions in extra/Configs/Config.in. Signed-off-by: Anthony G.

2014-09-09libc: add fallocate() and fallocate64()Anthony G. Basile
We add the Linux-specific function fallocate() which allows the user to directly manipulate allocate space for a file. fallocate() can operate in different modes, but the default mode is equivalent to posix_fallocate() which is specified in POSIX.1.

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.

2014-04-23weak 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.

It is better than crashing but still wrong since errno handling is removed. With the patch, errno_location is restored back in test program. 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 <__GI_mmap+0x24> 8284: eb000010 bl 82cc <__errno_location> 8288: e3a03016 mov r3, #22 828c: e5803000 str r3, [r0] Cc: Christian Ruppert <christian.ruppert@abilis.com> CC: Francois Bedard <Francois.Bedard@synopsys.com> Cc: Anton Kolesov <Anton.Kolesov@synopsys.com> Cc: Joern Rennecke <joern.rennecke@embecosm.com> Cc: Jeremy Bennett <jeremy.bennett@embecosm.com> Cc: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Cc: Peter Korsgaard <peter@korsgaard.com> Cc: Khem Raj <raj.khem@gmail.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
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.

2014-02-15libc: Fix sync_file_range.c for MIPS64 N32 ABISteve Ellcey
The special sync_file_range handling is only needed for the O32 ABI (regardless of whether it is on mips32 or mips64). The N32 (and N64) ABI's should both use the standard code. This routine was using the special code for the N32 ABI because that ABI has a word size of 32 bits and that is wrong. This patch fixes it by checking the ABI used instead of checking the word size.

2013-11-06Fix weak/strong attribute of __errno_location and it's __GI aliasVineet Gupta
A simple statically linked hello world program was segfaulting for ARC in linuxthreads.old configuration (although the root casue applies cross-arch for NPTL as well as linuxthreads.old as described) The crash was due to branch to NULL in _stdio_init 0001026c <_stdio_init>: 1026c: push_s blink 1026e: st.a r13,[sp,-8] 10272: bl.d 0 --> supposed call to __errno_location The call was NOT getting patched to libc internal only alias __GI___errno_location, because it was weak while it's exported cousin, __errno_location was strong/normal. arc-linux-uclibc-nm libc/misc/internals/__errno_location.os 00000000 W __GI___errno_location 00000000 T __errno_location This is exactly opposite to what is expected. Quoting Peter S. Mazinger, commit 87936cd013041 "errno and *_init cleanup" | The rule adopted: | for enabled threads we make in libc the __GI_x() variants strong, x() weak | and (should) provide another strong x() in libpthread. | If threads are disabled, even the __GI_x() variants are weak. With the fix, we see the right settings as below 00000000 T __GI___errno_location 00000000 W __errno_location Note that problem won't show up in a static busybox build as it references errno and that seems to elide the issue. I can confirm the same/more issues with latest ARM buildroot builds w/o my fix.

2013-07-04libc/sysdeps/linux/common/sendfile.c: fix sendfile64 visibilityAnthony G. Basile
Commit a83ea57a50 introduces code for falling back on sendfile64 when the sendfile syscall is not available. However, as written, that code leads to sendfile64 being globally hidden in situations where __NR_sendfile and __USE_LARGEFILE64 are defined. In this case, the flow executes strong_alias_untyped(sendfile,sendfile64) in libc/sysdeps/linux/common/sendfile.c and libc_hidden_proto(sendfile64) in include/sys/sendfile.h, but nowhere does it do libc_hidden_def(sendfile64). This patch adds the needed libc_hidden_def(sendfile64). This breaks, for example, xfsprogs on x86_64. Reported by mardok4 in IRC. Signed-off-by: Anthony G.

2013-04-07linux: pread/write: fix 64bit handlingMike Frysinger
The syscall on 64bit ports takes 4 args as there is no need to split up the value into two args. Add support for that to the common code. Once we fix that, the mips code can now leverage it for its 64bit and 32bit needs. However, we can't just drop it entirely yet because its n32 ABI needs special handling to treat it like a 64bit port. This does change the existing behavior which treats the n32 like a 32bit port, but we want to do this. In the future, we'll probably have to introduce a define for this as it currently affects x86_64/x32 and mips/n32. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-04-01linux: pread/write: convert to SYSCALL_ALIGN_64BITMike Frysinger

SuperH is funky and also allows us to do this. We should be able to merge the mips version too, but that'll require someone to take a closer look as the current stuff doesn't look quite right.

2013-04-01libc: rename TRUNCATE64_HAS_4_ARGS to SYSCALL_ALIGN_64BITMike Frysinger

Since this alignment affects more than just truncate64, rename the define to properly document its purpose. This also allows us to expand it to the other impacted syscalls (which will be done in a follow up commit). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
