* Cygwin: strace: print windows and cygwin pid in event outputCorinna Vinschen2019-03-233-13/+42
| | | | | | | | | | | | | | strace only printed the Windows PID in event output so far. Especially now that Windows and Cygwin PID are decoupled, the strace user might like to see the Cygwin pid in event output as well. However, at process startup, the process might not have a Cygwin PID yet. To mitigate this, always print the Windows PID and only add the Cygwin pid if it exists.

* Cygwin: wcsxfrm_l: Only byte swap if dest size is > 0Corinna Vinschen2019-03-192-9/+15
| | | | | | | | | | | commit c0d7d3e1a2fa96db15613cbd68a68c96966bc402 removed the usage of the LCMAP_BYTEREV flag in the call to LCMapStringW to workaround a strange bug in LCMapStringW. This patch didn't take a userspace call of wcsxfrm{_l} with NULL buffer and 0 size to evaluate the required buffer size into account. This introduced a crash trying to byte swap the NULL buffer. This patch fixes that problem. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* AMD GCN: Implement circular buffering.Andrew Stubbs2019-03-181-17/+38
| | | | | | | | | | | | | | | | | | | The GCN port outputs stdout and stderr via a shared-memory interface. Previously the buffer was limited to 1000 write operations, which was enough for testing purposes, but easy to exhaust. This patch implements a new circular buffering system allowing a greater amount of output. The interface must allow hundreds of hardware threads to output simultaneously. The new limit is UINT32_MAX write operations. Unfortunately, there's no way to tell if the host side has also been updated. This code will misbehave unless the gcn-run from GCC is also updated (although it's fine the other way around), but that patch has already been committed. OK?

* Add semihosting docs for nios2 and m68kcygwin-3_0_4-releaseJeff Johnston2019-03-142-0/+411
| | | | | | | | | | | Author: Sandra Loosemore <sandra@codesourcery.com> Date: Wed Mar 13 20:22:16 2019 -0700 Add semihosting documentation for nios2 and m68k. QEMU maintainers have asked for a specification of the nios2 semihosting interface. Since it's essentially a copy of the m68k implementation, this patch adds a document for that target as well.

* Cygwin: ps: simplify codeCorinna Vinschen2019-03-121-47/+18
| | | | | | | | | Always use NtQuerySystemInformation(SystemProcessIdInformation). This drops two code paths calling NtQueryInformationProcess or GetModuleFileNameExW and only requires to open the process to fetch system time info. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Cygwin: ps: show *all* processes in ps -W outputCorinna Vinschen2019-03-121-32/+51
| | | | | | | | | | | | | | | There's a long-standing bug in ps -W. It only shows processes which ps can open with PROCESS_QUERY_LIMITED_INFORMATION permissions. However, that fails for a lot of system processes. Due to that, output is basically restricted to processes in the same session, as well as Cygwin processes... which isn't *quite* what ps -W was supposed to do. Basically we only need to open the process to fetch the image name. If that fails, utilize the undocumented SystemProcessIdInformation info class introduced with Windows Vista, which allows to fetch the image name by specifying the PID. Restructure the code a bit.

* Cygwin: loadavg: improve debugging of load_initCorinna Vinschen2019-03-122-17/+27
| | | | | | | | | | | | | | When logging in via ssh with an unprivileged account, PdhAddEnglishCounter returns with status 0x800007D0, PDH_CSTATUS_NO_MACHINE. We didn't find any workaround but the changes to improve debugging output may help in future. Using UNICODE instead of ANSI functions is a result of trying to fix this problem. Also drop the prototype workaround for PdhAddEnglishCounterA. It's not required anymore since Mingw-w64's pdh.h catched up. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Cygwin: proc: return more useful cmdlineCorinna Vinschen2019-03-121-6/+3
| | | | | | | | | | Creating /proc/<PID>/cmdline requires permissions to communicate with the target process via its signal pipe.

* Cygwin: posix timers: fix a deadlockcygwin-3_0_3-releaseCorinna Vinschen2019-03-082-0/+5
| | | | | | | | | | | | Canceling the timer thread runs under lock. The thread uses the same lock to guard its timer_tracker struct access. If the timing is bad, timer_settime or timer_delete grab the lock at the same time, the timer expires. In the end, cancel waits for the thread sync while the thread waits for ther lock to be released. Fix this by not waiting for the thread sync under lock.

| | | | | | | | | | | We don't support setting groups via /etc/groups anymore. Also, the initgroups group list is created via S4U, so we have "Interactive" vs. "Network" token, an artificial and entirely irrelevant difference.

| | | | | | | | | | | | | Per MSDN VirtualQueryEx requires PROCESS_QUERY_INFORMATION. Testing showed that PROCESS_QUERY_LIMITED_INFORMATION is sufficient since Windows 8.1. The assumption that Windows 8 is the same as Windows 8 was not correct, it requires PROCESS_QUERY_INFORMATION as well.

* Cygwin: load_user_profile: Don't give primary domain to ldapCorinna Vinschen2019-03-021-14/+7
| | | | | | | | If the user domain is the primary domain, LDAP is supposed to use the default naming context. This is accomplished by setting domain name to NULL in the call to cyg_ldap::fetch_ad_account. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

| | | | | | | | | | | cyg_ldap::fetch_ad_account creates a naming context from the incoming domain, if it's not NULL.

| | | | | | | | | | | | A sleep is required on Windows 10 64 bit only before calling RegisterClassW in the timerfd thread, and only when running under strace. One of the child processes inheriting the timerfd descriptor will get a STATUS_FLOAT_INEXACT_RESULT exception inside of msvcrt.dll. It's apparently some timing problem.

Move share handles into timerfd_tracker class. - Drop shared instance counter since it's not required anymore. timerfd_shared only stores the actual timer data. - Drop timerfd_shared::create, just set clock id. - Drop timerfd_shared::dtor, it's not required anymore. - Drop timerfd_tracker::close, just call dtor where required. - Rename timerfd_tracker::increment_instances to timerfd_tracker::dup. It's the only reason it exists... - timerfd_tracker::dtor now checks the non-shared pointers for NULL before attempting to close them. - timerfd_tracker::dtor handles decrementing the local instance count by itself. - Add a method timerfd_tracker::init_fixup_after_fork_exec to set non-shared pointers to NULL. Together with the dtor patches it fixes a problem with close_on_exec timerfd descriptors. - Fix a bug in handling the thread synchronization event. It's actually nice to create it before using it... - Drop using sec_none{_nih} in InitializeObjectAttributes. It's an unnecessary roundabout route just to get a NULL pointer. - Slightly rework timechange window handling. - Add more comments to explain what happens. fhandler_timerfd: - Drop cnew macro, it just hides what happens. - fhandler_timerfd::fixup_after_exec now calls timerfd_tracker::init_fixup_after_fork_exec first, so a subsequent call to timerfd_tracker::dtor only works on valid handles. - fhandler_timerfd::close directly calls timerfd_tracker::dtor now. - Drop dtor call in fhandler_timerfd destructor.
