"Test WHS" Builder is back!

by Colin Finck

Hi all, Back in April, our server farm used for building had to leave its hosting site (cf. https://reactos.org/archives/public/ros-dev/2016-April/017775.html). A single server was set up at the new site and I estimated to have our old server farm back up by May or June. Unfortunately, this still hasn't happened. Our server farm is still at its old location and I cannot give a timeframe when it will finally be shipped to the new location. As we cannot wait forever for this to happen, I put up the old Windows Home Server VM on our single new server and reintegrated it into BuildBot ("Test WHS" builder). Its performance won't match the former one for sure. Instead of 4GB of RAM, it's currently at mere 1GB and it builds on HDD instead of RAM-Disk. Nevertheless, it should be fully operational at least. If this works out well, I'll see if I can also get our Win7 builder up again. This would give us "Build GCCWin_x86", "Build MSVC_x64" and "Build MSVC_x86". I cannot resurrect the VMware and VBox testers right now though. This will definitely need another machine. Will look after this in October. Maybe we can also get a RAM upgrade for the existing machine to enable building on RAM Disks again. Cheers, Colin

Fully agree with Thomas.. That is wrong.. Attributes are not handles. Further, this replicates the unacceptable behavior of the Windows shell, whereby an entire list of files is dropped when just one fail. I've argued, some years ago, that such lists should be continued, ideally adding failed files to a "failed" list to be presented to the user. You can *not* make any valid assumption of whether other files in the list will fail just because one of them doesn't exist, or cant be moved because it's locked, or whatever. That you are currently writing on this code gives you a good opportunity to make our shell better than Microsoft's in this regard.

Re: [ros-dev] [ros-diffs] [dchapyshev] 72655: [NtUser] Try to fix tests for user32:EnumDisplaySettings

by Thomas Faber

I've seen like 4 people change this stuff recently and not one of them got it 100% right. So here are the rules for how to use probes and SEH: * Probe pointers before accessing them. This ensures you're not reading kernel mode memory (and does pretty much nothing else) * Never access user mode pointers outside of SEH. The application controls its address space, so protection, physical memory mapping and contents can change out from under you at any point. For most purposes, MmProbeAndLockPages is the only way to get around this. * Sometimes there is no alternative to copying data to kernel memory. If there is a pointer stored in user mode memory, you need a copy of it because you can't rely on it not changing after your probe (even if you lock down the memory). * In case of an exception you usually want to return the exception code. There are exceptions (heh) to this rule, but if you think you've found one, better be sure and show it with a test. * If you make a pool allocation whose size is directly influenced by user mode input, there's a good chance you'll want to use ExAllocatePoolWithQuotaTag In particular this means: * Probing something or accessing it once does not save you from using SEH every single time you access the user mode memory * Probing UserModePointer->StructMemberPointer is never correct, you need to make a copy of the struct or that particular member, since the memory can change * The ProbeForReadUnicodeString function is not useful unless you use its return value Hope this helps. Thanks for hanging in there. -T On 2016-09-11 18:13, dchapyshev(a)svn.reactos.org wrote: > Author: dchapyshev > Date: Sun Sep 11 16:13:46 2016 > New Revision: 72655 > > URL: http://svn.reactos.org/svn/reactos?rev=72655&view=rev > Log: > [NtUser] Try to fix tests for user32:EnumDisplaySettings > > Modified: > trunk/reactos/win32ss/user/ntuser/display.c > > Modified: trunk/reactos/win32ss/user/ntuser/display.c > URL: http://svn.reactos.org/svn/reactos/trunk/reactos/win32ss/user/ntuser/displa… > ============================================================================== > --- trunk/reactos/win32ss/user/ntuser/display.c [iso-8859-1] (original) > +++ trunk/reactos/win32ss/user/ntuser/display.c [iso-8859-1] Sun Sep 11 16:13:46 2016 > @@ -443,7 +443,7 @@ > { > /* No device found */ > ERR("No PDEV found!\n"); > - return STATUS_UNSUCCESSFUL; > + return STATUS_INVALID_PARAMETER_1; > } > > *ppdm = ppdev->pdmwDev; > @@ -474,7 +474,7 @@ > { > /* No device found */ > ERR("No device found!\n"); > - return STATUS_UNSUCCESSFUL; > + return STATUS_INVALID_PARAMETER_1; > } > > iFoundMode = 0; > @@ -571,13 +571,18 @@ > > _SEH2_TRY > { > - ProbeForWrite(lpDevMode, sizeof(DEVMODEW), 1); > + ProbeForRead(lpDevMode, sizeof(DEVMODEW), 1); > + > + cbSize = lpDevMode->dmSize; > + cbExtra = lpDevMode->dmDriverExtra; > + > + ProbeForWrite(lpDevMode, cbSize + cbExtra, 1); > } > _SEH2_EXCEPT(EXCEPTION_EXECUTE_HANDLER) > { > _SEH2_YIELD(return _SEH2_GetExceptionCode()); > } > - _SEH2_END > + _SEH2_END; > > if (lpDevMode->dmSize != sizeof(DEVMODEW)) > { > @@ -586,31 +591,30 @@ > > if (pustrDevice) > { > - if (pustrDevice->Buffer == NULL || pustrDevice->Length == 0) > - { > - Status = STATUS_INVALID_PARAMETER_1; > - } > - > /* Initialize destination string */ > RtlInitEmptyUnicodeString(&ustrDevice, awcDevice, sizeof(awcDevice)); > > _SEH2_TRY > { > /* Probe the UNICODE_STRING and the buffer */ > - ProbeForRead(pustrDevice, sizeof(UNICODE_STRING), 1); > - ProbeForRead(pustrDevice->Buffer, pustrDevice->Length, 1); > + ProbeForReadUnicodeString(pustrDevice); > + > + if (!pustrDevice->Length || !pustrDevice->Buffer) > + ExRaiseStatus(STATUS_NO_MEMORY); > + > + ProbeForRead(pustrDevice->Buffer, pustrDevice->Length, sizeof(UCHAR)); > > /* Copy the string */ > RtlCopyUnicodeString(&ustrDevice, pustrDevice); > } > _SEH2_EXCEPT(EXCEPTION_EXECUTE_HANDLER) > { > - _SEH2_YIELD(return _SEH2_GetExceptionCode()); > - } > - _SEH2_END > + _SEH2_YIELD(return STATUS_INVALID_PARAMETER_1); > + } > + _SEH2_END; > > pustrDevice = &ustrDevice; > - } > + } > > /* Acquire global USER lock */ > UserEnterShared(); > @@ -642,11 +646,6 @@ > /* Copy some information back */ > _SEH2_TRY > { > - ProbeForRead(lpDevMode, sizeof(DEVMODEW), 1); > - cbSize = lpDevMode->dmSize; > - cbExtra = lpDevMode->dmDriverExtra; > - > - ProbeForWrite(lpDevMode, cbSize + cbExtra, 1); > /* Output what we got */ > RtlCopyMemory(lpDevMode, pdm, min(cbSize, pdm->dmSize)); > > @@ -663,13 +662,6 @@ > Status = _SEH2_GetExceptionCode(); > } > _SEH2_END; > - } > - else > - { > - if (Status == STATUS_UNSUCCESSFUL) > - { > - Status = STATUS_INVALID_PARAMETER_1; > - } > } > > return Status; > >

Infrastructure team application - Resending after subscribing

by Vyronas Tsingaras

Dear all, My name is Vyron Tsingaras a 23 year old currently employed as a Systems and Network Administrator at AMD Telecom S.A. My work duties involve maintainance and installation of Linux servers, XenSerevr hypervisors, networking equipment (Cisco ISR, Cisco ITP, Cisco ASA, Fortigate firewalls, Mikrotik routers, pfSense firewalls) and basic MySQL administration. I love using Ops automation tools (pref. Ansible) and have experience scripting and developing in Python. I have followed ReactOS for quite some time and me being an unqualified programmer for systems programming for contributing code to such a complex project I feel that this is a position I am better qualified for. I am from Greece (UTC+2) and my work hours are 9-5.30. I will be available after work hours and on weekends always providing notifcation if I will be unavailable. I feel excited at the prospect of contributing to an open source project of this scale and look forward to working with all of you should I be accepted. Best Regards, Vyron Tsingaras.
