* Fix thread priority handlingCorinna Vinschen2016-05-201-9/+11
| | | | | | | | | | | | | | | So far pthread::postcreate() only sets the thread priority at all, only if the inherit-scheduler attribute is PTHREAD_EXPLICIT_SCHED. This completely ignores the PTHREAD_INHERIT_SCHED case, since in contrast to POSIX, a thread does not inherit its priority from the creating thread, but always starts with THREAD_PRIORITY_NORMAL. pthread_getschedparam() only returns what's stored in the thread attributes, not the actual thread priority. This patch fixes both problems. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Rewrite scheduler functions getting and setting process and thread priorityCorinna Vinschen2016-05-202-172/+173
| | | | | | | | | | | | | | | | So far the scheduler priority handling is not POSIX compatible. The priorities use a range of -14 up to +15, which means it's not clear if the POSIX-required return value of -1 in case of an error is *really* an error or just the valid priority value -1. Even more confusing, -14 is the *max* value and 15 is the *min* value. Last but not least this range doesn't match the POSIX requirement of at least 32 priority values. This patch cleans up scheduler priority handling and moves the valid priority range to 1 (min) - 32 (max). It also adds a function sched_get_thread_priority() which will help to make thread priority more POSIX-like. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Sync toplevel configure with upstream GCC.Anton Kolesov2016-05-202-46/+24
| | | | | | | | | | | | | | | | | | | | This fixes a problem, where libgloss wouldn't be built for ARC processors, even though it is actually supported. The original patch that introduced support for ARC in libgloss hasn't been submitted to GCC maillist, hence when top-level configure has been synced with GCC - this libgloss patch has been effectively reverted. Libgloss support for ARC has been accepted in GCC: https://gcc.gnu.org/ml/gcc-patches/2016-05/msg01148.html ChangeLog 2016-05-17 Anton Kolesov <Anton.Kolesov@synopsys.com> * configure.ac: Sync with upstream GCC. * configure: Regenerate.

Sure, I've attached the patch. Wilco Add a simple rawmemchr implementation. Use strlen for rawmemchr(s, '\0') as it is the fastest way to search for '\0', and use memchr with an infinite size for other cases. This is 3x faster for large sizes.

* Make sure to have full configuration info in sys/_types.h.Corinna Vinschen2016-05-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | The following testcase: $ cat > test.c <<EOF #include <sys/select.h> #include <sys/time.h> EOF $ gcc -c test.c emits the following error: /usr/include/sys/reent.h:276:3: error: expected specifier-qualifier-list befor e ‘_fpos64_t’ _fpos64_t _EXFNPTR(_seek64, (struct _reent *, _PTR, _fpos64_t, int)); ^ The reason is that the load order from sys/select.h includes sys/_types.h before sys/config.h has been included from anywhere else. sys/_types.h defines _fpos64_t only if __LARGE64_FILES is defined, but it never is in this scenario. So sys/_types.h has to make sure to get the configuration info by itself. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Fix support ARC processors without barrel-shifterJeff Johnston2016-05-021-1/+6
| | | | | | | | | | | | | | | | | crt0.S for ARC used to use instruction "asr.f lp_count, r3, 2" for all cores except ARC601. However instructions which shift more than 1 bit are optional, so this crt0.S didn't worked for all ARC cores. Luckily this is a shift just by 2 bits on all occassions, so fix is trivial - use two single-bit shifts. libgloss/ChangeLog 2016-04-29 Anton Kolesov <anton.kolesov@synopsys.com> * arc/crt0.S: Fix support for processors without barrel-shifter.

* Update crt0.S for ARC.Jeff Johnston2016-05-021-9/+23
| | | | | | | | | | | | | | | | | | | | | | | | | This is similar to commit 06537f05d4b6a0d2db01c6afda1d2a0ea2588126 to the newlib for ARC. GCC for ARC has been updated to provide consistent naming of preprocessor definitions for different optional architecture features: * __ARC_BARREL_SHIFTER__ instead of __Xbarrel_shifter for -mbarrel-shifter * __ARCEM__ instead of __EM__ for ARC EM cores * __ARCHS__ instead of __HS__ for ARC HS cores * etc (not used in libgloss) This patch updates crt0.S for ARC to use new definitions instead of a deprecated ones. To ensure compatibility with older compiler new definitions are also defined in crt0.S if needed, based on presence of deprecated preprocessor definitions. libgloss/ChangeLog 2016-04-29 Anton Kolesov <Anton.Kolesov@synopsys.com> * arc/crt0.S: Use new GCC defines to detect processor features.

* Don't test pthread objects for being already initialized at init timeCorinna Vinschen2016-04-201-12/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | For all pthread init functions, POSIX says Results are undefined if pthread_FOO_init() is called specifying an already initialized pthread_FOO object. So far our pthread init functions tested the incoming object if it's already an initialized object and, if so, returned EBUSY. That's ok *iff* the object was already initialized. However, as the example in https://cygwin.com/ml/cygwin/2016-04/msg00473.html shows, an uninitialized pthread object could also accidentally look like an initialized object and then returning EBUSY is not ok. Consequentially, all those tests are dangerous. Per POSIX, an application has to know what its doing when calling any of the pthread init functions anyway, and re-initializing the object is just as well as undefined behaviour as is returning EBUSY on already initialized objects. * thread.cc (pthread_attr_init): Drop check for already initialized object.

* Disallow S_ISGID on directories without default ACL entriesCorinna Vinschen2016-04-191-1/+13
| | | | | | | | | | | | | | | | | | | | We can't handle the S_ISGID bit if the child didn't inherit a NULL SID ACE with the S_ISGID bit set. On directories without default ACL entries we would have to add an inheritable NULL SID ACE and nothing else. This in turn results in permission problems when calling set_file_sd from set_created_file_access. That's fixable, but it would only work for files created from Cygwin while files created from native Windows tools end up with really ugly permissions. This patch only makes sure that the S_ISGID bit is reset for a directory if it has no inheritable ACEs. Still having the 's' bit shown in ls or getfacl output would be misleading. So, calling `setfacl -k' on a dir also removes the S_ISGID bit now. * sec_acl.cc (set_posix_access): Drop S_ISGID bit on directories without inheritable ACEs. Explain why.

* Handle permissions a bit closer to POSIX 1003.1eCorinna Vinschen2016-04-182-10/+10
| | | | | | | | | | | | | | | | | | | | So far we tweaked ACL_GROUP_OBJ and ACL_MASK values the same way when creating a file. We now do what POSIX requires, namely just change ACL_MASK if it's present, otherwise ACL_GROUP_OBJ. Note that we only do this at creation time. Chmod still tweaks both to create less surprising results for the unsuspecting user. Additionally make sure to take umask only into account if no ACL_MASK value is present. That has been missed so far. * sec_acl.cc (set_posix_access): Perform check for non-existant default ACEs earlier. Ignore umask also if ACL_MASK is present. Only set owner_eq_group if we're actually handling a user entry.
