However, the ownership is never acquired in the v6_dma_inv_range function when cleaning the first line and flushing the last one, in case the address is not aligned to D_CACHE_LINE_SIZE boundary. Fix this by reading/writing data if needed, before performing cache operations. While at it, fix v6_dma_flush_range to prevent RWFO outside the buffer.

At present, nwfpe contains assembly code which isn't Thumb-2 compatible, and for now it doesn't appear useful to port this code. All ARMv7-A/R platforms necessarily have VFPv3 hardware floating- point natively, making emulation unnecessary.

This will avoid accidentally configuring a broken kernel where the config otherwise would allow multiple architecture versions to coexist in the same kernel. Not adding !CPU_V5 etc., because the chance of anyone trying to put v5 and v7 in the same kernel is low, and I'm not aware of any mach which can do this. These could be added later if it matters. Note that the rules may need to be refined if support for the ARM1156J(F)-S processor is later added to the kernel, since this processor supports the rare ARMv6T2 extensions, which add support for Thumb-2 and a few other ARMv7 features.

This patch adds the icache_line_size macro which reads the CTR register. The main loop in v7_coherent_*_range is split in two independent loops or the D and I caches. This also has the performance advantage that the DSB is moved outside the main loop.

We end up violating this when we do prom console writes, because we use an on-stack buffer to translate '\n' into '\r\n'. So instead, do this translation into an intermediate buffer, which is in the kernel image and thus below 4GB, then pass that to the PROM console write calls. On the 32-bit side we don't have to deal with any of these issues, so the new prom_console_write_buf() uses the existing prom_nbputchar() implementation. However we can now mark those routines static. Since the 64-bit side completely uses new code we can delete the putchar bits as they are now completely unused. Signed-off-by: David S.

This bug causes the response of the system to certain attacks to be ineffective. It also prevents wpa_supplicant from getting scan results, as wpa_supplicant disables countermeasures on startup - preventing the hardware from scanning. wpa_supplicant works with ap_mode=2 despite this bug because the commit handler re-enables the port. The log tends to look like: State: DISCONNECTED -> SCANNING Starting AP scan for wildcard SSID Scan requested (ret=0) - scan timeout 5 seconds EAPOL: disable timer tick EAPOL: Supplicant port status: Unauthorized Scan timeout - try to get results Failed to get scan results Failed to get scan results - try scanning again Setting scan request: 1 sec 0 usec Starting AP scan for wildcard SSID Scan requested (ret=-1) - scan timeout 5 seconds Failed to initiate AP scan.

In these situations, you are usually trying to connect to a new AP, so keeping TKIP countermeasures active is confusing. This is already how the driver behaves (inadvertently). However, querying SIOCGIWAUTH may tell userspace that countermeasures are active when they aren't. Clear the setting so that the reporting matches what the driver has done..

To avoid copying the skb unnecessarily move the skb_copy call below the checks that don't need write access to the skb. Also, move the assignment of nh_pos and h_pos below the skb_copy to point to the correct skb. It would be possible to avoid another resize of the copied skb by using skb_copy_expand instead of skb_copy but that would make the patch more complex. Also, shared skbs are a corner case right now, so the resize shouldn't matter much.
