2018-02-03bits/mman.h: consolidate header fileWaldemar Brodkorb
Sync with GNU C library and consolidate duplicate non architecture specific defines. MAP_UNINITIALIZED is only defined to 0x4000000 and used by the Linux kernel when CONFIG_MMAP_ALLOW_UNINITIALIZED is enabled. CONFIG_MMAP_ALLOW_UNINITIALIZED is only available for nommu. See Documentation/nommu-mmap.txt.
2017-11-25statfs.h: add f_flagsWaldemar Brodkorb
Add missing member in struct statfs. It is used by xfsprogs (f.e. 4.13.1). Reported-by: Joshua Kinard <kumba@gentoo.org>
2017-11-22remove misleading comment about f_frsize fieldEugene Rudoy
It is supported both in the sense of being contained in mips version of statfs/statfs64 structs and also in the sense that it's filled by the corresponding kernel syscalls. It is UNsupported in that sense that it's value is the same as that of f_bsize (at least on older kernel versions, the oldest version tested is 2.6.13), s.

2015-06-10siginfo: add signal info for seccomp related SIGSYSDaniel Golle
uClibc doesn't define signal info for the SIGSYS signal which is issued in case of hitting a syscall prohibited by seccomp. This is sad as it makes debugging seccomp filter policies impossible on some architectures (at least ARM and PowerPC, maybe also others) which do not coincidentally set si_value.sival_int as the syscall number. To fix this, import the definitions and macros needed from glibc. Signed-off-by: Daniel Golle <daniel@makrotopia.org> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2014-04-01Fix warnings in MIPS buildSteve Ellcey
This patch fixes the rest of the set-but-not-used warnings in the MIPS code by using attribute_unused and also fixes some conversion warnings by changing __arch_compare_and_exchange_xxx_[8|16]_int. Assigning __cmp (int type) to __prev (pointer type) generates a warning. Assigning zero to each separately avoids this warning without having to add a cast.

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.

2014-02-02libc: mips: Fix setjmp/longjmp for MIPS64 N64 ABIWaldemar Brodkorb
When booting a Linux system with qemu-system-mips64 the execution of $(pwd) in the ash shell triggers a segmentation fault. Ash uses setjmp/longjmp for exception handling. After looking at the glibc implementation, I found some differences, with this patch tries to resolve. Now the system boots up fine and no segmentation faults occur. The global pointer should be restored and the types for the register values should be wide enough.

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>

2013-04-07linux: 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: readahead: convert to SYSCALL_ALIGN_64BITMike Frysinger
The readahead syscall has the 64bit register align issue for all arches. Only mips was handling this though. Clean up the common readahead.c to use the SYSCALL_ALIGN_64BIT define so that we can throw away the mips version and make this work correctly on arm/ppc/xtensa. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-04-01mips: only define SYSCALL_ALIGN_64BIT for O32 ABIsMike Frysinger
The 64bit register alignment issue only affects the O32 ABI, so wrap the define accordingly. We don't want this being used for N32 ABIs. This doesn't directly affect the N64 ABI since these files wouldn't even be compiled for those targets (no need for the 32bit/64bit shim). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2013-04-01libc: rename TRUNCATE64_HAS_4_ARGS to SYSCALL_ALIGN_64BITMike Frysinger
The reason truncate64 takes 4 args on some arches is that their ABI requires 64bit values to be aligned on register pair boundaries. 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>
