* libc/fts: Use O_CLOEXEC for internal file descriptors.Jilles Tjoelker2012-09-272-10/+14
| | | | | | | | | | | | Because fts keeps internal file descriptors open across calls, making such descriptors close-on-exec helps not only multi-threaded applications but also single-threaded applications. In particular, this prevents passing a temporary file descriptor for saving the current directory to processes created via find -exec. Notes: svn path=/head/; revision=241010
* Ensure that all cases that enqueue a netgraph item for delivery by aRyan Stone2012-09-271-1/+1
| | | | | | | | | | | | | | | | ngthread properly set the item's depth to 1. In particular, prior to this change if ng_snd_item failed to acquire a lock on a node, the item's depth would not be set at all. This fix ensures that the error code from rcvmsg/ rcvdata is properly passed back to the apply callback. For example, this fixes a bug where an error from rcvmsg/rcvdata would not previously propagate back to a libnetgraph consumer when the message was queued.

* sigaction(2),sigwait(2),sigwaitinfo(2): Remove [EFAULT] error condition.Jilles Tjoelker2012-09-273-16/+3
| | | | | | | | | | | | | | | | | Passing an invalid pointer results in undefined behaviour. The wrappers in libthr access some of the data pointed to by the arguments in userland, so that an invalid pointer will cause a signal and not an [EFAULT] error return. Furthermore, if the [EFAULT] error occurs when the kernel is writing, it is not a proper error in the sense that the call still commits (changing the signal disposition or accepting the signal).

* Revert r240931, as the previous comment was actually in sync with POSIX.Pawel Jakub Dawidek2012-09-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have to note that POSIX is simply stupid in how it describes O_EXEC/fexecve and friends. Yes, not only inconsistent, but stupid. In the open(2) description, O_RDONLY flag is described as: O_RDONLY Open for reading only. Taken from: http://pubs.opengroup.org/onlinepubs/9699919799/functions/open.html Note "for reading only". Not "for reading or executing"! In the fexecve(2) description you can find: The fexecve() function shall fail if: [EBADF] The fd argument is not a valid file descriptor open for executing. Taken from: http://pubs.opengroup.org/onlinepubs/9699919799/functions/exec.html As you can see the function shall fail if the file was not open with O_EXEC! And yet, if you look closer you can find this mess in the exec.html: Since execute permission is checked by fexecve(), the file description fd need not have been opened with the O_EXEC flag. Yes, O_EXEC flag doesn't have to be specified after all. You can open a file with O_RDONLY and you still be able to fexecve(2) it. Notes: svn path=/head/; revision=241000

* Kernel and modules have "set_vnet" linker set, where virtualizedMikolaj Golub2012-09-271-1/+98
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | global variables are placed. When a module is loaded by link_elf linker its variables from "set_vnet" linker set are copied to the kernel "set_vnet" ("modspace") and all references to these variables inside the module are relocated accordingly. The issue is when a module is loaded that has references to global variables from another, previously loaded module: these references are not relocated so an invalid address is used when the module tries to access the variable. The example is V_layer3_chain, defined in ipfw module and accessed from ipfw_nat. The same issue is with DPCPU variables, which use "set_pcpu" linker set. Fix this making the link_elf linker on a module load recognize "external" DPCPU/VNET variables defined in the previously loaded modules and relocate them accordingly. For this set_pcpu_list and set_vnet_list are used, where the addresses of modules' "set_pcpu" and "set_vnet" linker sets are stored. Note, archs that use link_elf_obj (amd64) were not affected by this issue. Reviewed by: jhb, julian, zec (initial version) MFC after: 1 month Notes: svn path=/head/; revision=240997

* Implementing pmap_kextract(va) as pmap_extract(kernel_pmap, va) isAlan Cox2012-09-273-51/+69
| | | | | | | | | | | | | | | | | problematic because some callers to pmap_kextract() expect its implementation to be lock-less. In particular, uma_dbg_alloc() implicitly requires this. Otherwise, lock-order reversals occur between pmap locks and UMA zone locks. So, this change introduces a lock-less implementation of pmap_kextract(). Disable recursion on the pvh global lock in the new armv6 pmap. While recursion on this locks occurs in the old arm pmap, it thankfully doesn't occur in the armv6 pmap.

After a whole bunch of hacking/testing, I discovered that they weren't being early-dropped by the stack (but I should look at ensuring that later..) but were even making to the hardware transmit queue. They were mostly even being received by the remote end. However, the remote end was completely ignoring them. This didn't happen under 150-170MBit TCP tests as I'm guessing the TX queue stayed very busy and the STA didn't do any scanning. However, when doing 100Mbit/s of TCP traffic, the STA would do background scanning - which involves it coming in and out of powersave mode with the AP. Now, this is a total and utter hack around the real problems, which are: * I need to implement proper power save handling and integrate it into the filtered frames support, so the driver/stack doesn't send frames whilst the station is actually in sleep; * .. but frames were actually making it to the STA (macbook pro) and the AP did receive an ACK; but a tcpdump on the receiving side showed the EAPOL frame never made it. So the stack was dropping it for some reason; * Importantly - the EAPOL frames are currently going into the non-QoS TID, which maps to the BE queue and is susceptible to that queue being busy doing other things, but; * There's other traffic going on in the non-QoS TID from other contexts when scanning is going on and it's possible there's some races causing sequence number/IV issues, but; * Importantly importantlly, I think the interaction with TID 16 multicast traffic in power save mode is causing issues - since I -believe- the sequence number space being used by the EAPOL frames on TID 16 overlaps with the multicast frames that have sequence numbers allocated and are then stuffed on the cabq. Since with EAPOL frames being in TID 16 and queued to the BE queue, it's going to be waiting to be serviced with all of the aggregate traffic going on - and if the CABQ gets emptied beforehand, those TID 16 multicast frames with sequence numbers will go out beforehand. Now, there's quite likely a bunch of "stuff happening slightly out of sequence" going on due to the nature of the TX path (read: lots of overlapping and concurrent ath_start() and ath_raw_xmit() calls going on, sigh) but I thought I had caught them all and stuffed each TID TX behind a lock (that lasted as long as it needed to in order to get the frame onto the relevant destination queue - thus keeping things in order.) Unfortunately the last problem is the big one and I'm going to stare at it some more. If it _is_ So this is a work around for now to ensure that EAPOL frames actually make it out before any other stuff in the non-QoS TID and HOPEFULLY before the CABQ gets active. I'm now going to spend a little time in the TX path figuring out exactly why the sender is rejecting things. There's two (well, three if you count EAPOL contents invalid) possibilities: * The sequence number is out of order (ie, something else like the multicast traffic on CABQ) is going out first on TID 16; * The CCMP IV is out of order (similar to above - but less likely, as the TX key for multicast traffic is different to unicast traffic); * EAPOL contents strangely invalid.
