* [MAC80211]: Improve sanity checks on injected packetsAndy Green2007-10-10
| | | | | | | | | | | | 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.

* [MAC80211]: implement ERP info change notificationsDaniel Drake2007-10-10
| | | | | | | | | | | | 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.

* [MAC80211]: improved short preamble handlingDaniel Drake2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | 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]: Add LONG_RETRY flag to ieee80211_tx_controlIvo van Doorn2007-10-10
| | | | | | | | | | | | | | | | | | | | | 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: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: Jiri Benc <jbenc@suse.cz> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* [MAC80211]: STA reassociation improvementsDaniel Drake2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Daniel Drake <dsd@gentoo.org> Signed-off-by: Jiri Benc <jbenc@suse.cz> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| * [TCP]: Fix fastpath_cnt_hint when GSO skb is partially ACKedIlpo Järvinen2007-10-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When only GSO skb was partially ACKed, no hints are reset, therefore fastpath_cnt_hint must be tweaked too or else it can corrupt fackets_out. The corruption to occur, one must have non-trivial ACK/SACK sequence, so this bug is not very often that harmful. There's a fackets_out state reset in TCP because fackets_out is known to be inaccurate and that fixes the issue eventually anyway. In case there was also at least one skb that got fully ACKed, the fastpath_skb_hint is set to NULL which causes a recount for fastpath_cnt_hint (the old value won't be accessed anymore), thus it can safely be decremented without additional checking.

|/ | | | | | | | | | | | | | 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: Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* | fix bogus reporting of signals by auditAl Viro2007-10-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Async signals should not be reported as sent by current in audit log. As it is, we call audit_signal_info() too early in check_kill_permission(). Note that check_kill_permission() has that test already - it needs to know if it should apply current-based permission checks. So the solution is to move the call of audit_signal_info() between those. Bogosity in question is easily reproduced - add a rule watching for e.g. kill(2) from specific process (so that audit_signal_info() would not short-circuit to nothing), say load_policy, watch the bogus OBJ_PID entry in audit logs claiming that write(2) on selinuxfs file issued by load_policy(8) had somehow managed to send a signal to syslogd...
