The new ACLs now store the POSIX ACL MASK/CLASS_OBJ permission mask, and they allow to inherit the S_ISGID bit. ACL inheritance now really works as desired, in a limited, but theoretically equivalent fashion even for non-Cygwin processes. To accommodate Windows default ACLs, the new code ignores SYSTEM and Administrators group permissions when computing the MASK/CLASS_OBJ permission mask on old ACLs, and it doesn't deny access to SYSTEM and Administrators group based on the value of MASK/CLASS_OBJ when creating the new ACLs. The new code now handles the S_ISGID bit on directories as on Linux: Setting S_ISGID on a directory causes new files and subdirs created within to inherit its group, rather than the primary group of the user who created the file. This only works for files and directories created by Cygwin processes. 2015-05-29 Corinna Vinschen <corinna@vinschen.de> Reapply POSIX ACL changes. * utils.xml (setfacl): Show new option output.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch adds strlen.S to contain the complementary preprocessor logic to strlen-stub.c intended to provide #inclusion of alternative .S implementations.

* Fix multilib libgloss selection.Marcus Shawcroft2015-11-122-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Regression testing newlib in conjunction with libgloss and --enable-multilib can result in incompatible multilib versions of newlib and libgloss being used during link. This manifests on ARM target when newlib regression is run using a GCC configured using --with-multilib-list=aprofile With this configuration many of the multilib variants built are mutually incompatible. The issue is that the newlib dejagnu foo iterates each multilib variant and correctly chooses the appropriate newlib variant but always chooses the root/base libgloss variant. The implementation of newlib/testsuite/lib/flags.exp contains the following fragment: set target_build_path "$objdir/$multibuildtop.." The effect of this fragment is to explicitly select the root version of libgloss, irrespective of the current multilib. Digging around in VC it appears that the original implementation of multlib magic came into the tree back in 2002 with: 6e9d950a (Thomas Fitzsimmons 2002-05-01 17:06:25 +0000 39) In this initial version of multilib support, newlib was multilib capable, but libgloss was not multilib capable, hence the necessity to explicitly select the root libgloss version. Subsequently flags.exp was modified to support out of tree testing: cec1d3b4 (Jeff Johnston 2005-07-05 00:11:50 +0000 25) This change is orthogonal to this issue, its effect is to exit early in none multilib configurations. Subsequently libgloss gained --enable-multilib support, the relevant change is: https://sourceware.org/ml/newlib/2006/msg00440.html commit 00a4b31ad08aef361c5d74125ece410b4c285975 Author: Jeff Johnston <jjohnstn@redhat.com> Date: Wed May 10 20:51:41 2006 +0000 This change enabled multilib support throughout libgloss, but ommitted to adjust the flag.exp behaviour which anchors the libgloss multilib selection to the base version. The attached patch adjusts flags.exp to select the current multilib variant of libgloss. 2015-11-06 Marcus Shawcroft <marcus.shawcroft@arm.com> * testsuite/lib/flags.exp (libgloss_link_flags): Drop multilibtop from target_build_path.
* makedoc: Don't interpret license text as a commandJon Turney2015-11-122-8/+16
| | | | | | | | | | | | | | | | | | | | | | | | Align makedoc's iscommand() with it's documentation, and don't allow commands to contain a space. A command is a line containing only a sequence of capital letters or '_', followed by optional spaces. This prevents "IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE" (the only line in the license text which consists of only capitals and spaces, without any punctuation) from being interepreted as a makedoc command, leading to: "Can't find IMPLIED" "warning, IMPLIED is not recognised" being emitted by makedoc, (which is normally un-noticed because makedoc's stderr is redirected to a .ref file) 2015-11-06 Jon Turney <jon.turney@dronecode.org.uk> * doc/makedoc.c (iscommand): Only allow commands to have trailing spaces, not space separated words.

* doc: Fix some inconsistent QUICKREF linesJon Turney2015-11-126-5/+18
| | | | | | | | | | | | | | | | | | | | | | makedoc defines a command as 'all upper case, and alone on a line'. A few QUICKREF lines currently violate this by having some additional text after the QUICKREF. So, currently, these lines are treated as an unknown command. This is benign as QUICKREF currently does nothing but produce some ignored output on stderr. I'm not sure what the intent of QUICKREF is. 2015-11-06 Jon Turney <jon.turney@dronecode.org.uk> * libm/mathfp/s_acos.c: Fix QUICKREF. * libm/mathfp/e_acosh.c: Ditto. * libm/math/w_asin.c: Ditto. * libm/mathfp/e_acosh.c: Ditto. * libm/mathfp/s_acos.c: Ditto.

* makedoc: Fix INTERNAL(|DEFINITION|FUNCTION) command definitionsJon Turney2015-11-122-4/+9
| | | | | | | | | | | | | | | | | | | | | The unused INTERNAL_DEFINITION, INTERNAL_FUNCTION and INTERNAL commands are defined in terms of the non-existent built-in 'func' This causes every single invocation of makedoc to output "Can't find func" three times, as it parses doc.str. This is normally un-noticed because makedoc's stderr is redirected to a .ref file. Fix these unused command definitions to something with equivalent lack of effect, but without generating an error. 2015-11-06 Jon Turney <jon.turney@dronecode.org.uk> * doc/doc.str: Fix INTERNAL_DEFINITION, INTERNAL_FUNCTION and INTERNAL.

* Avoid .eh_frame in ARM newlib.Joseph Myers2015-11-128-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | ARM newlib has various strcmp implementations that use .cfi_* directives to generate unwind information. The effect of this is that the generated objects contain .eh_frame sections. However, ARM uses its own unwind info format, not .eh_frame, which is generated by ARM-specific directives, not .cfi_*. The .eh_frame sections are useless, but also not removed by strip and may be loaded into memory at runtime. This patch fixes this by using .cfi_sections .debug_frame (as in glibc) so that the directives generate .debug_frame instead. .debug_frame is useful for the debugger, can be removed by strip, and is not loaded into memory at runtime. * libc/machine/arm/strcmp-arm-tiny.S: Use .cfi_sections .debug_frame. * libc/machine/arm/strcmp-armv4.S: Likewise. * libc/machine/arm/strcmp-armv4t.S: Likewise. * libc/machine/arm/strcmp-armv6.S: Likewise. * libc/machine/arm/strcmp-armv6m.S: Likewise. * libc/machine/arm/strcmp-armv7.S: Likewise. * libc/machine/arm/strcmp-armv7m.S: Likewise.

* Reorganize memchr selection.cygwin-2_3_0-releaseMarcus Shawcroft2015-11-067-124/+117
| | | | | | | | | | | | | | | | | | | | | The patch cleans up the auto configury mechanism used to select different implementations of memchr for various architecture versions. The approach here is to remove the selection of memchr within automake and instead use complimentary logic in memchr-stub.c and memchr.S to choose between the gerneric memchr.c implementation or one of the architecture specific implementations. This patch also changes the selection criteria inline with the previous proposal here: https://sourceware.org/ml/newlib/2015/msg00752.html but using the ACLE predefines. Regressed for armv7-a armv5 armv8-a, correct selection of memcpy implementation by manual inspection of a test program built for these three architectures.
