* Revert "Remove inclusion of sys/select.h in sys/types.h for backward compat"Yaakov Selkowitz2016-03-171-0/+2
| | | | | | This BSDism is still in use (e.g. putty). This reverts commit 088f7a723962dd18dcae09e8e8fa168bbea6ed0b.
* Feature test macros overhaul: sys/time.hYaakov Selkowitz2016-03-171-5/+8
| | | | | | | The inclusion of <sys/select.h> is required also by POSIX.1-2001. setitimer is XSI, and futimesat is GNU. Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
* Feature test macros overhaul: sys/stat.hYaakov Selkowitz2016-03-171-10/+6

* Feature test macros overhaul: string.hYaakov Selkowitz2016-03-171-23/+15
| | | | | | | | | | | | | | Throughout, remove __STRICT_ANSI__ and use the proper internal macros. bcmp, bcopy, bzero, index, and rindex were in POSIX prior to 2008. memrchr is GNU. strdup and strndup are POSIX.1-2008. The int-returning form of strerror_r is POSIX.1-2001. Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
* Feature test macros overhaul: stdlib.hYaakov Selkowitz2016-03-175-54/+73
| | | | | | | | | | | | | | | | | | | | Throughout, simplify the C99/C11 conditionals, and replace __STRICT_ANSI__ with the proper internal POSIX macros. The _*_r reentrant functions need not be guarded (and most haven't been) because such names in the global scope are reserved to the implementation. atoff is unique to newlib. dtoa is not actually exported (_dtoa_r is used internally), is nonstandard, and the declaration conflicts with the code included in MySQL, NSPR, and SpiderMonkey. mktemp was removed in POSIX.1-2001. The qsort_r declarations are reordered so that the GNU version retains precedence. Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
* Feature test macros overhaul: stdio.hYaakov Selkowitz2016-03-172-33/+46
| | | | | | | | | | | | | | Throughout, remove references to __STRICT_ANSI__ and use the proper internal macros and versions for C99, POSIX, ATFILE for the various *at functions, or LARGEFILE for fseeko and ftello. [v]asprintf are GNU extensions, but the *iprintf, *iscanf, and *asnprintf functions are unique to newlib. getw and putw were removed from POSIX.1-2001. funopen is BSD, and fopencookie is GNU.

* Feature test macros overhaul: signal.hYaakov Selkowitz2016-03-172-15/+11
| | | | | | | | | | | | Use proper internal macros for BSD sig_t and GNU sighandler_t. sigaltstack and friends are XSI even in SUSv4 but in glibc are nonetheless handled as POSIX.1-2008 (not 2001). The requirement for the ucontext_t typedef in signal.h was XSI prior to POSIX.1-2008. Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
* Feature test macros overhaul: pwd.hYaakov Selkowitz2016-03-171-2/+2

* Feature test macros overhaul: math.hYaakov Selkowitz2016-03-171-20/+23
| | | | | | | | | Simplify the C99 conditionals. Mark the drem and gamma functions as BSD|SVID, the Bessel double functions also XSI and the floats also SUSv3. signgam is BSD|SVID|XSI, and matherr is SVID. Finally, use the internal macros to control the symbolic constants. Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>

* Feature test macros overhaul: fcntl.hYaakov Selkowitz2016-03-171-14/+14
| | | | | | | | | | Most of the !_POSIX_SOURCE code is BSD, although ironically some were added to POSIX.1-2001. Use the ATFILE conditional for most of the *at functions, except futimesat which is GNU. Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>
* Feature test macros overhaul: dirent.hYaakov Selkowitz2016-03-172-4/+12

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the complete rework of the feature tests macros for better compatibility with GNU libc, primarily based on the Linux man pages documentation: http://man7.org/linux/man-pages/man7/feature_test_macros.7.html The previous implementation was flawed in its approach that macros were often used to hide symbols if defined (e.g. !defined __STRICT_ANSI__ or !defined _POSIX_SOURCE), whereas the approach of glibc is that these macros make symbols available when defined (e.g. defined _BSD_SOURCE, or as used internally, #if __BSD_VISIBLE). As much open-source software is written with glibc in mind, this necessitated patching numerous packages just to compile. In particular, __STRICT_ANSI__ (which is defined by gcc -ansi or -std=c*) was given too much importance. This implementation limits the influence of __STRICT_ANSI__ to controlling the default when no other feature test macros are defined, and to the inclusion of <alloca.h> in <stdlib.h> as documented. These are the only places where __STRICT_ANSI__ should be tested. The following macros are now accepted: _ATFILE_SOURCE, _BSD_SOURCE, _DEFAULT_SOURCE, _ISOC99_SOURCE, _ISOC11_SOURCE, _LARGEFILE_SOURCE, _SVID_SOURCE, _XOPEN_SOURCE_EXTENDED. The existing __*_VISIBLE internal macros have been kept mostly compatible with the original BSD implementation, with some changes to the criteria which controls them. Several more macros in this style have been added where needed for concision or accuracy. Enabling C++11 or newer in the compiler also enables C99 and C11 functions. Doing so should help move away from the need to define _GNU_SOURCE in g++ for _GLIBCXX_USE_C99 support as on Linux: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=51749 Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>

* cygwin_getaddrinfo: workaround Winsock getaddrinfo issue with broken DNSCorinna Vinschen2016-03-141-1/+10
| | | | | | | | | | | | | | | | | | Add experimental code to workaround the issue described in the thread starting at https://cygwin.com/ml/cygwin/2015-07/msg00350.html There's a hint in https://communities.vmware.com/message/2577858#2577858 that this problem is related to using the AI_ALL flag. This patch checks if GetAddrInfoW returned with WSANO_RECOVERY and if the AI_ALL flag was set, it retries GetAddrInfo without the AI_ALL flag. * net.cc (cygwin_getaddrinfo): Add experimental code to retry GetAddrInfoW without AI_ALL flag if it returned with WSANO_RECOVERY.

* Don't write NULL SID ACE if it's not necessary.Corinna Vinschen2016-03-131-4/+17
| | | | | | | | | | | | | If the ACL is supposed to reflect only standard POSIX permissions, and if the permissions are so that user has more perms than group and group has more perms than other, we don't really need the NULL SID ACE. If the permissions are that simple, get_posix_access will not call AuthZ. * sec_acl.cc (set_posix_perms): Don't write NULL SID ACE if it's not required. Explain why.

* Update setvbuf to latest OpenBSD implementationCorinna Vinschen2016-03-121-42/+75
| | | | | | | | | | | | | | | | | | Newlib's setvbuf function is very old and has two bugs: - It sets the SRD/SWR flags incorrectly in case of files opened for reading and writing. See https://cygwin.com/ml/cygwin/2016-03/msg00180.html for a desription of the effect. - It always sets the buffer size to BUFSIZ if it's not provided by the application, independent of the optimal blocksize for the underlying IO device. Update setvbuf to latest code from OpenBSD to fix both problems. * libc/stdio/setvbuf.c (setvbuf): Import latest OpenBSD implementation. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

| | | | | | | | | | | | Per the preceeding comment this inline code is disabled since 1993(!) because of a bug in GCC at the time. This is long gone and the equivalent inline code is used in the BSDs for quite some time. Enable this code for newlib as well. * libc/include/stdio.h (__sputc_r): Enable GCC inline code.

* Fix reading/writing Samba ACLs using RFC2307 mappingCorinna Vinschen2016-03-123-18/+82
| | | | | | | | | | | | | | | | | | | | When using RFC2307 uid/gid-mapping on Samba shares, the POSIX ACL contains the Windows SIDs. When writing back such an ACL we have to map the Windows SIDs back to the corresponding Samba SIDs representing the UNIX uid/gid value. When reading Samba SIDs, make sure never to evaluate a UNIX user account as group. * sec_acl.cc (set_posix_access): Convert Windows SIDs to RFC2307-mapped Sambe UNIX SIDs. * sec_helper.cc (cygpsid::get_id): Skip UNIX user accounts when trying to evaluate a SID as group. Skip UNIX group accounts when trying to evaluate a SID as user. * cygheap.h (cygheap_ugid_cache::reverse_get): New method to get nfs id from cygwin id.

* Add cygsid methods to create SIDs from scratchCorinna Vinschen2016-03-123-23/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | So far creating cygsids requires to generate an "S-1-..." string which is then converted to a SID by cygsid::getfromstr. Add two new methods: - cygsid::create (DWORD auth, DWORD subauth_count, ...) ... is a variable length list of subauth_count DWORD values being the actual subauths. - cygsid::append (DWORD rid) allows to append a single RID to an alreaday constituted SID. * security.h (cygsid::create): Declare public. (cygsid::append): Ditto. * sec_helper.cc (cygsid::create): Implement. (cygsid::append): Implement. * uinfo.cc (pwdgrp::fetch_account_from_windows): Use both new methods as appropriate. Drop setting csid from string. Create SID strings for printing SIDs only. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
