Michael Wu noticed that the skb length checking is not taken care of enough when a packet is presented on the Monitor interface for injection. This patch improves the sanity checking and removes fake offsets placed into the skb network and transport header. Signed-off-by:

zd1211rw and bcm43xx are interested in being notified when ERP IE conditions change, so that they can reprogram a register which affects how control frames are transmitted. This patch adds an interface similar to the one that can be found in softmac. Signed-off-by:

Similarly to CTS protection, whether short preambles are used for 802.11b transmissions should be a per-subif setting, not device global. For STAs, this patch makes short preamble handling automatic based on the ERP IE. For APs, hostapd still uses the prism ioctls, but the write ioctl has been restricted to AP-only subifs. ieee80211_txrx_data.short_preamble (an unused field) was removed. Unfortunately, some API changes were required for the following functions: - ieee80211_generic_frame_duration - ieee80211_rts_duration - ieee80211_ctstoself_duration - ieee80211_rts_get - ieee80211_ctstoself_get Affected drivers were updated accordingly.

mac80211 informs the driver what the short and long retry values are through set_retry_limit(), but when packets are being transmitted it did not inform the driver which of the 2 retry limits should actually be used. Instead it sends the actual value, but for drivers that can only set the retry limit and the register and in the descriptor need to indicate which of the limits should be used this is not really useful. This patch will add a IEEE80211_TXCTL_LONG_RETRY_LIMIT flag to the ieee80211_tx_control structure. By default the short retry limit should be used but if the flag is set the long retry should be used. This does not prevent the driver to ignore the request for "no retry" packets, but at least those will be send out with the short retry limit. But there is no perfect cure for this problem.. :( Signed-off-by:

My cheapy D-Link AP behaves strangely w.r.t reassociations. The following sequence of commands causes me to lose association and to be unable to regain it: ifconfig eth8 down ifconfig eth8 up iwconfig eth8 essid <x> This is because mac80211 tries to reassociate, rather than just associate. My AP replies with an association response (not a reassociation response...) denying the association with code 12: "Association denied due to reason outside the scope of this standard" mac80211 tries this reassociation another 4 times or so before finally giving up. I see 2 problems here: 1. bringing the interface down and up again should be resetting interface state i.e. after the interface is brought down, it should have no memory of if or where it was previously associated 2. after the first reassociation fails, mac80211 should fall back to standard association for the next attempt Signed-off-by: -

The sta_info code has some awkward locking which prevents some driver callbacks from being allowed to sleep. This patch makes the locking more focused so code that calls driver callbacks are allowed to sleep. It also converts sta_lock to a rwlock. Signed-off-by:

The ieee80211_rx_h_check handler really does two things, it's a lot easier to understand if it's split into ieee80211_rx_h_check and ieee80211_rx_h_load_key, and it may be possible in the future to optimise the key loading to not do it for each interface. Signed-off-by:

The recent mv_fill_sg() rewrite, to fix a data corruption problem related to IOMMU virtual merging, forgot to account for the potentially-increased size of the scatter/gather table after its run. Additionally, the DMA boundary is reduced from 0xffffffff to 0xffff to more closely match the needs of mv_fill_sg(). Signed-off-by:

This patch fixes a wrong ifdef in the board setup code, leading to the GPIO pin not being pulled high, and thus the USB switch not being powered at all. This finishes the rename of CONFIG_USB_OHCI to CONFIG_USB_OHCI_HCD, which started in 2005 (before 2.6.12-rc2), then probably because things were working anyway for most people got forgotten. [Ralf: Paolo's original patch didn't fix the module case, Florian's patch only fixed MTX1 etc. so this is a combined patch plus some cleanups.] Cc: Giuseppe Patanè <giuseppe.patane@tvblob.com> Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by:

When building a custom keymap, after setting GENERATE_KEYMAP := 1 in drivers/char/Makefile, the kernel build fails like this: CC drivers/char/vt.o make[2]: *** No rule to make target `drivers/char/%.map', needed by `drivers/char/defkeymap.c'. Stop. make[1]: *** [drivers/char] Error 2 make: *** [drivers] Error 2 This was caused by commit af8b1287, which deleted a necessary colon from the Makefile rule that generates the keymap, since that rule contains both a target and a target-pattern. The following patch puts the colon back: Signed-off-by:Maarten Bressers <mbres@gentoo.org> Cc: Yoichi Yuasa <yoichi_yuasa@tripeaks.co.jp> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: Sam Ravnborg <sam@ravnborg.org> Signed-off-by:

All the current page_mkwrite() implementations also set the page dirty. Which results in the set_page_dirty_balance() call to _not_ call balance, because the page is already found dirty. This allows us to dirty a _lot_ of pages without ever hitting balance_dirty_pages(). Not good (tm). Force a balance call if ->page_mkwrite() was successful. Signed-off-by:

When the ICMPv6 Target address is multicast, Linux processes the redirect instead of dropping it. The problem is in this code in ndisc_redirect_rcv(): if (ipv6_addr_equal(dest, target)) { on_link = 1; } else if (!(ipv6_addr_type(target) & IPV6_ADDR_LINKLOCAL)) { ND_PRINTK2(KERN_WARNING "ICMPv6 Redirect: target address is not link-local.\n"); return; } This second check will succeed if the Target address is, for example, FF02::1 because it has link-local scope. Instead, it should be checking if it's a unicast link-local address, as stated in RFC 2461/4861 Section 8.1: - The ICMP Target Address is either a link-local address (when redirected to a router) or the same as the ICMP Destination Address (when redirected to the on-link destination). I know this doesn't explicitly say unicast link-local address, but it's implied. This bug is preventing Linux kernels from achieving IPv6 Logo Phase II certification because of a recent error that was found in the TAHI test suite - Neighbor Disovery suite test 206 (v6LC.2.3.6_G) had the multicast address in the Destination field instead of Target field, so we were passing the test. This won't be the case anymore. The patch below fixes this problem, and also fixes ndisc_send_redirect() to not send an invalid redirect with a multicast address in the Target field. I re-ran the TAHI Neighbor Discovery section to make sure Linux passes all 245 tests now. Signed-off-by:Brian Haley <brian.haley@hp.com> Acked-by:
