2011-11-10net: add wireless TX status socket optionJohannes Berg1-0/+3
The 802.1X EAPOL handshake hostapd does requires knowing whether the frame was ack'ed by the peer. Currently, we fudge this pretty badly by not even transmitting the frame as a normal data frame but injecting it with radiotap and getting the status out of radiotap monitor as well. This is rather complex, confuses users (mon.wlan0 presence) and doesn't work with all hardware. To get rid of that hack, introduce a real wifi TX status option for data frame transmissions. This works similar to the existing TX timestamping in that it reflects the SKB back to the socket's error queue with a SCM_WIFI_STATUS cmsg that has an int indicating ACK status (0/1). Since it is possible that at some point we will want to have TX timestamping and wifi status in a single errqueue SKB (there's little point in not doing that), redefine SO_EE_ORIGIN_TIMESTAMPING to SO_EE_ORIGIN_TXSTATUS which can collect more than just the timestamp; keep the old constant as an alias of course. Currently the internal APIs don't make that possible, but it wouldn't be hard to split them up in a way that makes it possible. Thanks to Neil Horman for helping me figure out the functions that add the control messages. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

2011-10-18m68k: merge the mmu and non-mmu traps.c filesGreg Ungerer1-0/+6
The code for handling traps in the non-mmu case is a subset of the mmu enabled case. Merge the non-mmu traps_no.c code back to a single traps.c. There is actually no code mmu specific here at all, and the processor specific code (for the more complex 68020/68030/68040/68060) is already proplerly conditionaly used. The format of console exception dump is a little different, but I don't think will cause any one problems, it is purely for debug purposes. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2011-10-18m68k: merge mmu and non-mmu include/asm/entry.h filesGreg Ungerer3-312/+252
The changes in the mmu version of entry.h (entry_mm.h) and the non-mmu version (entry_no.h) are not about the presence or use of an MMU at all. The main changes are to support the ColdFire processors. The code for trap entry and exit for all types of 68k processor outside coldfire is the same. So merge the files back to a single entry.h and share the common 68k entry/exit code. Some changes are required for the non-mmu entry handlers to adopt the differing macros for system call and interrupt entry, but this is quite strait forward. The changes for the ColdFire remove a couple of instructions for the separate a7 register case, and are no worse for the older single a7 register case. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2011-10-18m68knommu: fix problems with SPI/GPIO on ColdFire 520xPeter Turczak2-17/+17
The problem has its root in the calculation of the set-port offsets (macro MCFGPIO_SETR() in arch/m68k/include/asm/gpio.h), this assumes that all ports have the same offset from the base port address (MCFGPIO_SETR) which is defined in mcf520xsim.h as an alias of MCFGIO_PSETR_BUSCTL. Because the BUSCTL and BE port do not have a set-register (see MCF5208 Reference Manual Page 13-10, Table 13-3) the offset calculations went wrong. Because the BE and BUSCTL port do not seem useful in these parts, as they lack a set register, I removed them and adapted the gpio chip bases which are also used for the offset-calculations. Now both setting and resetting the chip selects works as expected from userland and from the kernelspace.

2011-07-30m68k/atari: Reserve some ST-RAM early on for device buffer useMichael Schmitz1-2/+1
Based on an original patch from Michael Schmitz: Because mem_init() is now called before device init, devices that rely on ST-RAM may find all ST-RAM already allocated to other users by the time device init happens. In particular, a large initrd RAM disk may use up enough of ST-RAM to cause atari_stram_alloc() to resort to __get_dma_pages() allocation. In the current state of Atari memory management, all of RAM is marked DMA capable, so __get_dma_pages() may well return RAM that is not in actual fact DMA capable. Using this for frame buffer or SCSI DMA buffer causes subtle failure. The ST-RAM allocator has been changed to allocate memory from a pool of reserved ST-RAM of configurable size, set aside on ST-RAM init (i.e. before mem_init()). As long as this pool is not exhausted, allocation of real ST-RAM can be guaranteed. Other changes: - Replace the custom allocator in the ST-RAM pool by the existing allocator in the resource subsystem, - Remove mem_init_done and its hook, as memory init is now done before device init, - Remove /proc/stram, as ST-RAM usage now shows up under /proc/iomem, e.g. 005f2000-006f1fff : ST-RAM Pool 005f2000-0063dfff : atafb 0063e000-00641fff : ataflop 00642000-00642fff : SCSI Signed-off-by: Michael Schmitz <schmitz@debian.org> [Andreas Schwab <schwab@linux-m68k.org>: Use memparse()] [Geert: Use the resource subsystem instead of a custom allocator] Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
2011-07-27atomic: cleanup asm-generic atomic*.h inclusionArun Sharma1-2/+0
After changing all consumers of atomics to include <linux/atomic.h>, we ran into some compile time errors due to this dependency chain: linux/atomic.h -> asm/atomic.h -> asm-generic/atomic-long.h where atomic-long.h could use funcs defined later in linux/atomic.h without a prototype. This patches moves the code that includes asm-generic/atomic*.h to linux/atomic.h.

2011-07-25m68k: merge and clean up delay.h filesGreg Ungerer3-136/+94
The real difference between the mmu and non-mmu varients of the delay.h files has nothing to do with having an mmu or not. It is processor family differences that means slightly different code. Merge the delay_mm.h and delay_no.h files back into a single file. The primarly difference we need to deal with is whether the processor supports a 32bit * 32bit -> 64bit multiply. Without it we need to do some shift scaling as well as use a 32bit * 32bit -> 32bit multiply. If building for a multi-CPU type kernel then we must use the simpler mult/shift scaling. This version of delay code allows the CPU32 family to use a 64bit mul, since it supports this instruction, the old code did not. The changes use macros where appropriate to try and optimize constant sized udelay times. And it removes the use of a fixed lib function for the non-mmu case. Code size on typical kernel configurations is similar, or only larger by a few tens of bytes. Also removed the unused muldiv() code from delay_mm.h. Build and run tested on ColdFire and ARAnyM. Build tested only on 68328 and 68360 (CPU32). Signed-off-by: Greg Ungerer <gerg@uclinux.org>
2011-07-25m68knommu: correctly use trap_initGreg Ungerer1-1/+0
Currently trap_init() is an empty function for m68knommu. Instead the vectors are being setup as part of the IRQ initialization. This is inconsistent with m68k and other architectures. Change the local init_vectors() to be trap_init(), and init the vectors at the correct time during startup. This will help merge of m68k and m68knommu trap code in the furture.

2011-07-25m68k: merge mmu and non-mmu bitops.hGreg Ungerer3-837/+528
The following patch merges the mmu and non-mmu versions of the m68k bitops.h files. Now there is a good deal of difference between the two files, but none of it is actually an mmu specific difference. It is all about the specific m68k/coldfire varient we are targeting. So it makes an awful lot of sense to merge these into a single bitops.h. There is a number of ways I can see to factor this code. The approach I have taken here is to keep the various versions of each macro/function type together. This means that there is some ifdefery with each to handle each CPU type. I have added some comments in a couple of appropriate places to try and make it clear what the differences we are dealing with are. Specifically the instruction and addressing mode differences we have to deal with. The merged form keeps the same underlying optimizations for each CPU type for all the general bit clear/set/change and find bit operations. It does switch to using the generic le operations though, instead of any local varients. Build tested on ColdFire, 68328, 68360 (which is cpu32) and 68020+. Run tested on ColdFire and ARAnyM.

The non-MMU m68k targets can use the same asm/system.h as the MMU targets. So switch the current system_mm.h to be system.h and remove system_no.h. The assembly support code for the non-MMU resume functions needs to be modified to match the now common switch_to() macro. Specifically this means correctly saving and restoring the status flags in the case of the ColdFire resume, and some reordering of the code to not use registers before they are saved or after they are restored.

2011-05-28ns: Wire up the setns system callEric W. Biederman1-1/+2
32bit and 64bit on x86 are tested and working. The rest I have looked at closely and I can't find any problems. setns is an easy system call to wire up. It just takes two ints so I don't expect any weird architecture porting problems. While doing this I have noticed that we have some architectures that are very slow to get new system calls. cris seems to be the slowest where the last system calls wired up were preadv and pwritev. avr32 is weird in that recvmmsg was wired up but never declared in unistd.h. frv is behind with perf_event_open being the last syscall wired up. On h8300 the last system call wired up was epoll_wait. On m32r the last system call wired up was fallocate. mn10300 has recvmmsg as the last system call wired up. The rest seem to at least have syncfs wired up which was new in the 2.6.39. v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com> v3: ported to v2.6.36-rc4 by: Eric W.

2011-05-27arch: add #define for each of optimized find bitopsAkinobu Mita2-0/+10
The style that we normally use in asm-generic is to test the macro itself for existence, so in asm-generic, do: #ifndef find_next_zero_bit_le extern unsigned long find_next_zero_bit_le(const void *addr, unsigned long size, unsigned long offset); #endif and in the architectures, write static inline unsigned long find_next_zero_bit_le(const void *addr, unsigned long size, unsigned long offset) #define find_next_zero_bit_le find_next_zero_bit_le This adds the #define for each of the optimized find bitops in the architectures.

2011-05-27m68knommu: fix build error due to the lack of find_next_bit_le()Akinobu Mita1-0/+44
m68knommu can't build ext4, udf, and ocfs2 due to the lack of find_next_bit_le(). This implements find_next_bit_le() on m68knommu by duplicating the generic find_next_bit_le() in lib/find_next_bit.c.

2011-05-24m68knommu: remove stubs for __ioremap() and iounmap()Greg Ungerer1-3/+5
The implementation of iounmap() and __ioremap() for non-mmu m68k is trivial. We can inline them in m68knommu headers and remove the trivial implementations. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

2011-05-19input/atari: Use the correct mouse interrupt hookMichael Schmitz1-2/+0
The Atari keyboard driver calls atari_mouse_interrupt_hook if it's set, not atari_input_mouse_interrupt_hook. Fix below. [geert] Killed off atari_mouse_interrupt_hook completely, after fixing another incorrect assignment in atarimouse.c.
